As an important part of modern agricultural facilities, the glass greenhouse outdoor shading system has the functions of adjusting light, temperature and humidity to provide a suitable environment for plant growth. This article will detail the various components of a glass greenhouse outdoor shading system and their role.
1. External sunshade skeleton.
The external shading skeleton is an important part of the glass greenhouse, which is mainly used to support and fix the shading net. The outer sunshade skeleton is generally made of lightweight, durable materials, such as aluminum alloy, steel, etc. Its structural design is reasonable, easy to install, and can be customized according to different needs. The existence of the external shading skeleton can effectively prevent direct sunlight, reduce the internal temperature of the greenhouse, and reduce the evaporation of water in the greenhouse, so as to achieve the effect of energy saving and emission reduction.
2. The shade net is made of high-quality black external shade net.
The shade net is the core component of the outdoor shading system of the glass greenhouse, which mainly plays the role of adjusting the light intensity. When choosing a shade net, you should consider its material, color, durability and other factors. Black outer shade net is a high-quality shade net, made of high-density polyethylene material, which has the characteristics of wear resistance, aging resistance, high temperature resistance, etc. Its color is black, which effectively absorbs heat from the sun and lowers the temperature in the greenhouse. In addition, the black outer shade net also has an anti-UV function, which can protect the plant from UV rays.
3. Curtain line.
The curtain line is the link connecting the outer sunshade skeleton and the sunshade net, and its main function is to fix the sunshade net on the skeleton and keep it flat. The material and specifications of the curtain line need to be selected according to the specific greenhouse structure and the size of the shade net. When installing, it is necessary to pay attention to the length and tension of the curtain line to ensure that the shade net can be spread out smoothly while preventing it from causing damage to the plants.
Fourth, the transmission mechanism.
The transmission mechanism is the power to realize the automatic deployment and retraction of the sunshade net**. The motor drives the transmission shaft to run through the transmission mechanism, and the transmission shaft drives the driving rod to move in parallel on the curtain through the connector, and the driving rod pulls one end of the curtain to slowly expand. This transmission method ensures a smooth and accurate unfolding and retracting process of the shade net, and can also be manually controlled as needed. The control box is equipped with a manual control button, if you need to stop in the middle of the stop, you can press the stop button to stop the operation. In addition, the transmission mechanism also has a stroke limiter switch, when the sunshade net is all unfolded or retracted, the motor automatically stops running, and the stroke runs at the end. This design can effectively protect the motor and transmission system and extend its service life.
To sum up, the glass greenhouse outdoor shading system has significant advantages and characteristics as a modern agricultural facility. By reasonably selecting and configuring components such as external sunshade frame, sunshade net, curtain line and transmission mechanism, the adjustment of light, temperature and humidity in the greenhouse can be realized, and the best environment for plant growth can be provided. In addition, the external shading system can also effectively reduce the energy consumption in the greenhouse, reduce the burden on the environment, and have good economic and social benefits. In the future, with the continuous progress of technology and the expansion of application fields, glass greenhouse outdoor shading systems will play an important role in more fields.
