[0032] Embodiment one:

[0033] A leaking tool for seawater desalination reverse osmosis (RO) membrane shell PV water inlet and outlet joint, like Figures 1-4As shown, the plugging tool 1 comprises a top plate 101 and a bottom plate 102, and a gas bag ring 107 is arranged between the top plate 101 and the bottom plate 102. A valve core 106 is arranged on one side of the top of the top plate 101 and is in communication with the gas bag ring 107. The top plate 101 and the bottom plate 102 are made of hard rubber, and the gas bag ring 107 is made of flexible rubber. The top plate 101 and the bottom plate 102 of the plugging tool 1 are designed to be made of hard rubber, which ensures the firmness and stability of the tool during the plugging process. The gas bag ring 107 arranged between the top plate 101 and the bottom plate 102 is made of flexible rubber and can tightly fit the surface of the seawater desalination reverse osmosis RO membrane shell PV water inlet and outlet joint after being inflated through the valve core 106, thereby forming an effective seal to prevent water leakage. This design of combining rigidity and flexibility not only ensures the reliability of plugging but also improves the adaptability of the tool.

[0034] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , a handle 105 is arranged at the top axial center of the top plate 101, and two side ears 103 are arranged on both sides of the handle 105. The handle 105 arranged at the top axial center of the top plate 101 and the two side ears 103 on both sides of the handle 105 provide stable gripping points for the operator. This design not only makes the plugging tool 1 easier to operate and control, especially in emergency or high-altitude operations, but also effectively reduces the physical exertion of the operator, improving the safety and efficiency of the work.

[0035] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , a bolt 108 is threaded through the two side ears 103 and extends to the bottom of the bottom plate 102. The bolt 108 threaded through the two side ears 103 not only tightly connects the top plate 101 and the bottom plate 102 together but also enhances the overall structural strength of the plugging tool 1 through the threaded design. The extension of the bolt 108 to the bottom of the bottom plate 102 ensures that the tool will not loosen or fall off during the plugging process, thereby improving the stability and durability of the plugging.

[0036] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , a bolt head 104 is arranged at the top of the bolt 108, and a gasket 110 is sleeved on the bolt 108. The bolt head 104 arranged at the top of the bolt 108 facilitates the operator to use the tool for fastening or disassembly, and the gasket 110 sleeved on the bolt 108 can disperse the pressure generated during the tightening of the bolt, thereby protecting the top plate 101 from being crushed. This design not only improves the durability of the plugging tool 1 but also ensures the tightness of the bolt connection.

The nut 109 provided below the gasket 110 is screwed to the bolt 108. By tightening the nut 109, the top plate 101 and the bottom plate 102 can be firmly fixed together. This design not only enhances the structural stability of the leak-sealing tool 1, but also makes the tool easier and faster to disassemble, reducing maintenance costs and time costs.

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 After the nut 109 and bolt 108 are screwed together, the handle 105 can be fixed to the top of the top plate 101. This design prevents the handle 105 from loosening or falling off during use, improves the stability and safety of operation, and makes the leak-sealing tool 1 more stable and reliable when carried and stored.

[0040] See Figure 1 , Figure 2 , Figure 3 , Figure 4 Figure 1 Figure 2 Figure 3 Figure 4 The leak-sealing tool 1 can be plugged into the PV inlet and outlet water connector of the external seawater desalination reverse osmosis membrane housing. The plug-in design allows the leak-sealing tool 1 to easily adapt to connectors of different sizes and shapes. Operators only need to simply insert the tool into the connector to perform the leak-sealing operation, which greatly improves the efficiency and convenience of the work. At the same time, this design also enhances the versatility and adaptability of the leak-sealing tool 1.

[0041] The implementation principle of this utility model is as follows: First, ensure that all components of the leak-sealing tool 1 are intact, including the top plate 101, bottom plate 102, airbag ring 107, handle 105, side lug 103, bolt 108, bolt head 104, washer 110, and nut 109, etc. Then, align the bottom plate 102 of the leak-sealing tool 1 with the leaking part of the PV inlet / outlet water connector of the seawater desalination reverse osmosis membrane housing, ensuring that the two fit tightly together. By adjusting the tightness of the bolt 108, the top plate 101 and the bottom plate 102 are fixed together using the washer 110 and nut 109, while ensuring that the leak-sealing tool can be firmly stuck on the connector. Hold the handle 105 to ensure that the leak-sealing tool remains stable during installation.

[0042] The air bag ring is inflated by inflating the air valve core 106 into the air bag ring 107, the air bag ring is tightly adhered to the outer wall of the joint, the inflation of the air bag ring is observed, and it is ensured that the air bag ring forms an effective seal and blocks the water leakage point.
