Underwater installation of flow pushers is an important underwater salvage and rescue work for divers, which can help divers quickly locate and salvage shipwrecks and people overboard in an emergency. This article will introduce in detail the steps and precautions for installing a flow pusher underwater to help divers better complete underwater salvage and rescue work.
1. Understand the underwater environment.
Before installing the flow pusher, divers need to understand the underwater environment, including water current, water depth, water temperature, water quality, etc. This information can help divers assess the feasibility and safety of installing a flow pusher.
2. Choose the right flow pusher.
According to the underwater environment and mission requirements, choose the appropriate flow pusher. Factors such as the power, size, and weight of the flow pusher all need to be considered. Divers need to choose a flow pusher that can adapt to the underwater environment to ensure that it can work properly underwater.
3. Prepare tools and materials.
Divers need to prepare the tools and materials needed to install the flow pusher, including the flow pusher, batteries, cables, screwdrivers, pliers, paint, etc. These tools and materials need to ensure quality and safety.
4. Install the flow pusher.
1.Locate shipwrecks or people overboard.
Before installing the flow pusher, divers need to locate the wreck or person who has fallen overboard. The diver can locate the target by sonar, optical equipment, or the diver's own observation.
2.Prepare the flow pusher.
Before installing the flow pusher, the diver needs to check the integrity of the flow pusher to ensure that there is no visible damage or defects. At the same time, divers need to be prepared with the required tools and materials.
3.Install the flow pusher.
According to the position and attitude of the target, the diver needs to choose the appropriate installation position and method. Divers need to clean the surface of the target and apply the right amount of paint to increase the adhesion of the flow pusher. The diver then needs to mount the flow pusher to the target surface and secure it using a tool such as a screwdriver. Finally, divers need to check the installation of the flow pusher to make sure there are no problems such as loosening or leaking.
4.Check the working condition of the flow pusher.
After the installation is completed, the diver needs to check the operation of the flow pusher, including parameters such as water flow and current. If any problems are found, the diver needs to deal with it or replace the parts in a timely manner.
5. Precautions.
1.Before installing the flow pusher, divers need to conduct a full safety assessment to ensure the reliability of the underwater environment and equipment.
2.During installation, divers need to be stable and balanced to avoid accidents due to water currents or equipment issues.
3.After installation, divers need to inspect and maintain the equipment in time to ensure its proper operation and working life. At the same time, divers need to maintain communication with the surface command and report any problems or anomalies in a timely manner.
4.Throughout the underwater salvage and rescue process, divers need to follow relevant safety regulations and technical operating procedures to ensure their own safety and the safety of others. At the same time, divers need to keep the equipment clean and hygienic to avoid pollution or other hazards to the underwater environment.
