110 yuan to solve the world's problems
Chinese engineers have developed the national invention patent technology "Residential Emergency Water Supply Scheme".
Stop! 110 yuan to solve the world's problemsAs the saying goes, what can be solved with money is not a big deal, and now 110 yuan can't even afford a decent lunch, and you still have a "world problem"? This hasn't even started blowing you, the cowhide is already broken. First of all, what is the "world problem"?
Don't get excited, listen to me. There was a power outage, there was an emergency power supply, and there were emergency lights at home. But what about the water stopping? Do you have an emergency water source at home? At present, there is no timely and effective emergency water supply device in the residential water supply system. Even if they are notified before the water is stopped, residents can only use temporary water storage: use buckets and other containers to store a small amount of water for later use, which is inconvenient to store and use. If there is a sudden emergency water outage, there is nothing you can do. When I wake up in the morning and prepare to wash, I find that the water has stopped, and many people have experienced similar experiences. And the pressure and urgency of a sudden water outage is much greater than that of a power outage and food shortage. The tsunami caused by Tonga on January 15, 2022, Fukushima on March 16, 2022, and the Russia-Ukraine conflict are all emergencies. This is followed by food, electricity and communications. The first batch of supplies that China shipped to Tonga with 20 was bottled drinking water.
From July 29, 2023 to August 2, 2023, there was a flood in Fangshan, Beijing, and the first thing the victims needed was drinking water.
At that time, the municipal government can only send water trucks for emergency. The scene of residents queuing up to carry buckets and basins has happened from time to time in news reports and in reality. Even if the neighbor is decorating, it is very annoying and inconvenient to temporarily cut off the water for a few hours. Can you imagine what will happen to those who are lonely, disabled, old and weak, and will someone bring them water to their doors? This is also a real problem that countries around the world are currently facing.
In fact, from a purely technical point of view, the city's tap water technology has been mature for more than 100 years. Through the efforts of several generations of technical workers, there are many existing technologies that can effectively solve the problem of residential emergency water supply. It's not too difficult, but the aforementioned dilemma of emergency water cuts that is prevalent all over the world. Why can't it be solved so far?
There are purely technical problems here, as well as cognitive problems of humanistic concepts. When it comes to emergency response, the traditional use of water tanks is the simplest and most effective way. As long as it is not an extreme situation (Sima Guang incident, smashing the water tank), there will be no emergency problem. But with the water pipeline, after the water supply to the home, the water tank is redundant - the water in the water tank (water tank) is inconvenient to use, and it needs to be cleaned and maintained frequently. Water quality and sanitation are difficult to guarantee, and it occupies a lot of space indoors. Therefore, except in areas where the tap water supply is unstable, this method is naturally eliminated, and many old things, ideas, and objects are abandoned, but at the same time, the emergency water supply function is also abandoned. With the development of the economy and the progress of society, people have moved into modern living in high-rise buildings, and their lifestyles have changed.
Even under the condition that the tap water supply is relatively stable, the prior art also has a method of emergency water supply, that is, an emergency water tank is set up in the water supply system. The tanks in this technique are mostly open, and there are also problems with cleaning, maintenance, and water sanitation, as well as taking up space. This has led to the creation of closed water tanks, which have eliminated cleaning, maintenance and water quality issues. However, in order to achieve the function of emergency water supply, it is necessary to set up complex control elements for the emergency closed water tank, such as automatic valves, and even sensors and other components with complex and sophisticated technology. This kind of technology is an automatic emergency water supply method, which allows users to use up the water in the emergency water tank unconsciously (and this function itself also has a misunderstanding of application rationality, in the case of emergency water outage, the small amount of precious drinking water that is fortunate to be preserved is easily discharged and used unknowingly. Emergency tanks generally don't hold much water, and may last for several days in emergency use mode. If you use it normally, the water will be gone after a bath. Therefore, this form of technology seems to be very technological, but in fact, it cannot eliminate the problem of being caught off guard in an emergency. For example: the water is stopped just after taking a bath, and the person taking the bath does not know, the emergency system supplies water as usual, and the water in the water tank of the half-bath is also used up, and there is no water at all, how embarrassing.
As this type of technology increases the complexity of the system, it also increases the maintenance of the system, which is necessary to prevent the installation from being concealed. Therefore, the problem of occupying space cannot be resolved.
For the above reasons, although the existing technology can solve the problem of water supply emergency. But in the case that the operation of the modern water supply system is more and more stable (countries in the world provide various safeguards for safe water supply), the utilization rate of the residential emergency water supply device is not high, and a large number of necessary and high-use kitchenware, sanitary ware, gas water heater, electric water heater, gas meter, electricity meter, water meter and other facilities are installed in the bathroom and kitchen of the modern residence, so the device that the utilization rate is not high and occupies a certain amount of space is set up in the remaining very limited space, which will make people unwilling to accept. This makes it difficult to implement and promote existing emergency water supply technologies.
Although the current water supply system is becoming more and more stable and reliable, the incidence of emergency situations specific to the terminal (each household) is low. However, due to the huge size of the system, the absolute emergency workload for municipal emergencies is very huge. Therefore, in the social aspect, the practical problems and embarrassments described above will frequently occur. In this case, the emergency water supply truck has become the main way for the municipal department to explain to the public. For example, according to the official website of Beijing Water Supply Group, in 2003, the maintenance department dispatched 350 emergency water supply trucks, an average of 35 trips; In another example, the water affairs department of Fengtai District, Beijing recorded that from the beginning of the epidemic (December 8, 2019) to February 18, 2020, nearly 30 emergency water trucks were on duty; For another example, during the National Day in Beijing, 19 water trucks were on duty every day; According to Beijing** news: On July 23, 2021, the Beijing water supply department set off from Huairou that night to help Jiaozuo City, Henan Province, and dispatched water trucks and professional teams to provide 120 cubic meters of basic water per day (4 liters of water per person per day) for 30,000 local people. The efforts and costs of urgently organizing the mobilization of personnel, equipment, materials, and thousands of miles to help are unimaginable, however, for the local victims, it is still miserable, because the emergency response method that the international community mainly relies on and commonly uses obviously lacks sufficient timeliness, let alone comprehensive effectiveness. In addition, the transportation volume is large, the cost is high, and the social disturbance is large, so the economic and social costs are very high. This is actually a kind of helplessness, and it is better than nothing. On the one hand, the existing technology is difficult to implement and promote, and people are reluctant to use it, on the other hand, the municipal sector may be under great pressure at any time, which is the problem faced by residents and the world.
Following the launch of two innovative technologies, "passive exoskeleton weight-bearing walking device" and "shoulder-mounted cane-type moped", Chinese engineers have recently launched the national invention technology "Residential Emergency Water Supply Scheme" in order to solve the emergency problem of emergency water outage. In the Patent Gazette of the State Intellectual Property Office, Vol. 38, No. 1002, 2022, it was published on March 11. Publication number: CN114164892A
Patent No.: 2021114184763 (see figure: patent paper single book).
The main content of this invention:
The emergency water supply system is connected in series between the water supply line and the water supply valve (faucet, faucet) of the water equipment. The main body of the system is an emergency water tank, and the water tank is a sealed pressure vessel. A water inlet is provided at the top of the front end of the water tank, which is connected with the water supply network pipeline. At the bottom of the rear end of the water tank, a water outlet is set up (this setting is set to ensure that the water body entering the water tank can flow smoothly without dead lag) and is connected with the water supply cut-off door (faucet) of the water equipment, and the emergency water supply inlet and outlet pipe interface is set at the top of the water tank. And make the connected emergency water supply inlet and outlet air pipe connected with the emergency water supply air pipe cut door (water nozzle) that is arranged above the water supply cut-off door (faucet, water nozzle) of the water use equipment. The whole of the water tank and the whole of the emergency water supply inlet and outlet pipes, and the horizontal height of the water supply inlet and outlet door (water nozzle) outlet of the emergency water supply inlet and outlet should be higher than the horizontal height of the water supply door (faucet) outlet of the water supply equipment, so that a certain water level difference is formed, and this drop is the minimum value of the water outlet pressure of the water supply door (faucet) of the water supply equipment in the emergency water supply state (the water outlet pressure when the emergency water supply mode is started).
In order to make full use of the space, facilitate concealed installation, and increase the water storage capacity, the emergency water tank can be a special-shaped monomer, or a multi-body combination of series and parallel. The multi-body combination of emergency water tanks also needs to ensure the smooth flow of internal water bodies without stagnation. The top of each water tank that constitutes a multi-body water tank is provided with an inlet and outlet air pipe interface. And all the connecting pipes are gathered at the top of the water tank at the highest position to form an emergency water supply inlet and outlet pipe, and are connected with the emergency water supply inlet and outlet air pipe section door (water nozzle). So that the emergency water tank can be filled with water and the water supply can be emptied.
How this scenario works:
1. Under normal circumstances: operate according to the traditional water supply mode, the whole system is sealed, and the water supply is continuously pressurized.
2. In the event of an emergency water outage: the water supply system loses the water supply pressure, and there is no water available when the water equipment opens the door. At this time, open the "emergency water pipe cut-off door", and the water in the emergency water tank will automatically supply water to the water equipment below under the action of gravity, until the water in the water tank is used up, and then close the "emergency water pipe cut-off door" and the water equipment cut-off door. Wait for the system to restore water supply. It doesn't matter if the water goes out and the power goes out, the emergency water supply system can still work properly.
3. After the main water supply system restores the water supply, first open the "emergency water pipe cut-off door" to release the gas in the system, and close it immediately when the "emergency water pipe cut-off door" has water flowing out stably. The whole system can provide normal water supply.
How it works:
The principle of operation of this system is not a new concept of high technology. The ancient Chinese have long used it, and the current primary and secondary school students can understand it as soon as they hear it, and they can understand it at a glance, that is, the inkstone drop of the purple sand teapot or the inkstone filled with ink in the study, after the container is filled with water, block the vent hole on the container (the small hole on the lid of the pot) with your hand, and the water will not flow out, and you can control the water flow by controlling the opening and closing of the vent (equivalent to the "emergency water pipe cut-off door" of this device). Therefore, when the system is filled with water, the "emergency water pipe cut-off door" should be opened to discharge the air in the water tank and fill the water tank with water; When the water supply system loses water pressure (i.e. when there is an emergency water outage), the "emergency water pipe cut-off door" must be opened to release the water in the tank. As long as the "emergency water pipe cut-off door" is closed, the whole system becomes a fully sealed pressure vessel, without other control devices, sensors, etc., just like ordinary water pipelines, without special maintenance and cleaning, with the water supply, the water quality is automatically updated, and the use characteristics are no different from the existing ordinary water supply system. When the water supply system suddenly stops water and loses pressure, and there is no water outflow when the water valve is opened, the user will know that the water is stopped, and at this time, the water storage capacity of the residence and the prospect of water outage can be evaluated, and appropriate water use strategies can be adopted to prevent the ineffective waste of a small amount of drinking water retained in an emergency, which is also an important difference from the prior art, and can effectively avoid the occurrence of unexpected water use. Advantages of this scenario:
1. The whole system is sealed, and the water supply is normal under continuous pressure; The emergency water supply mode activated after the system loses pressure does not need external power, and relies on the water in the tank to supply water by gravity. The water body in the system (including the water in the water tank) is all connected to the operation, with the water supply, updated at any time, there is no dead lag, so its safety, hygiene, reliability and technical characteristics are no different from the traditional water supply system, no need to increase the repair and maintenance work. The operation of the emergency water supply is simple and convenient to use, and it is no different from the normal water supply method.
2. Simple structure, easy to make and install. It can be installed on the building structure in the ceiling structure of the water equipment room such as the kitchen, bathroom and other water equipment rooms of the residence, and can even be installed and laid in the same way as the commonly used water supply pipelines, power supply, heating and communication pipelines, and the installation and laying methods can be done in the wall without taking up additional indoor space, and the appearance effect of this scheme is compared with the appearance effect of the water supply equipment device that is now commonly used, but an extra section door (water faucet) is set up on the wall or cabinet next to the current faucet, Considering that existing sinks and sinks themselves may also have more than one faucet, this approach could easily be embraced and promoted, or could become a norm.
3. It has good economic and social benefits. Due to the simple structure and easy production and installation, the investment is small. According to the ceiling 5 square meters (ceiling area) * 01 meter (height of the space in the ceiling) gauge, 05 cubic meter water tank. It can provide two days of normal water consumption for a family of three residents in Beijing. In order to reduce the difficulty of installation and ensure the safety of the system structure, only 0The 1 cubic meter emergency water tank can also provide emergency water for a family of three in Beijing for two days. Each building has about 100 dwellings, and the water storage capacity can reach 10 cubic meters, which is equivalent to the capacity of a large emergency water truck. If this scheme is widely applied in cities and residential clusters, our houses can become "sponge houses", and cities will become real "sponge cities". If this technology is widely used in the house (this technology can provide at least two days of emergency drinking water for a family of three), the city can achieve at least two days of drinking water emergency capacity for the whole city without large-scale investment in construction, let alone special planning land, and without unified organization, scheduling and special operation and maintenance. Emergency drinking water can be stored in each house for more than two days. When the emergency is met, it is released by each household itself, just like a sponge automatically (without external power) water absorption and storage, and can be used randomly (if you need to use it, you will continue to store it with confidence) when you use it. This method not only realizes the emergency function, but also eliminates the social contradictions, disputes and transportation and management costs caused by the dispatch and allocation of precious water resources in emergency situations. In addition, each house can effectively reduce the waste of water and fully improve the efficiency of the use of precious drinking water in emergency situations. If you actively promote this technology, encourage residents to apply it when decorating their rooms, and apply measures such as the application of new residential buildings in the country, you don't have to plan land on a large scale, and you don't have to increase large capital investment.
Urban housing that implements this technology can achieve a sufficient, timely, comprehensive and effective response capability in emergency situations. This is something that has not been achieved in the current state of affairs in all countries of the world.
In the event of an emergency (emergency, natural disaster, war, etc.), two days of emergency water supply capacity is of great significance to a city. It has been reported that in the current Palestinian-Israeli conflict, Palestinian refugees in the war can only drink contaminated water from flush toilets, and if this technology is adopted, the same situation can ensure that refugees can get clean drinking water in the remaining water supply system.
According to the above technical scheme, the author installed a temporary and simple "emergency water supply system" in his own kitchen (see screenshot of the demonstration).
Reliable operation, easy to use, daily water use is the same as before, and completely solves the dilemma caused by sudden water outage.
The parts purchased for installation are as follows:
liter drinking water tank (can seal the pressure water supply) a 30 yuan.
Meter connection hose + connector three sets 70 yuan.
3. Emergency water pipe cut-off door (water nozzle) is 10 yuan.
A total of 110 yuan (these materials are available in supermarkets).
In case of an emergency water outage, 10 liters of spare water is enough to wash hands and vegetables, and it is enough to cook a meal.
It doesn't cost much, it's simple to install, it's easy to use, and it solves big problems. Lao Tzu said: The road is simple. This is a small invention, a big picture. The Chinese solutions provided by Chinese engineers to face the world's problems are important technologies of strategic significance for the construction and transformation of modern cities. Mass entrepreneurship and innovation. Today's move is related to people's livelihood and well-being, social stability, and the benefit of the country and the people.
