Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ship manufacturing, in particular to a grounding copper plate assembly tooling. Background Art
[0002] Due to the non-conductive characteristics of composite fiber materials, ships with composite fiber material structures are very different from ordinary metal ships in electrical grounding. Specifically, ships with composite fiber material structures must use special grounding copper plates at the part where the hull contacts the water body to complete the electrical grounding of the whole ship.
[0003] However, there is currently no unified installation standard for installing such grounding copper plates on ships with composite fiber material structures. The common practice is to embed the grounding copper plates on the outer side of the hull and use artificial glue coating to fixedly connect the grounding copper plates with the hull. The whole process is time-consuming and laborious, and the construction efficiency cannot be improved. In addition, large-area opening will damage the hull. After long-term use, the glue is corroded by seawater and gradually peeled off, and the grounding copper plates will become loose due to the failure of the glue. Seawater will also slowly seep into the hull along the gaps, making maintenance very difficult. Summary of the Utility Model
[0004] To solve the above technical problems, the purpose of the utility model is to provide a grounding copper plate assembly tooling, which realizes the effective connection between the grounding copper plate and the ship with composite fiber material structure by improving the grounding copper plate and its accessory structures, and ensures the long-term use of the grounding copper plate.
[0005] Based on this, the utility model provides a grounding copper plate assembly tooling, which includes a copper backplate, a grounding stud and a grounding copper plate. The copper backplate is attached to the inner side of the hull and is welded to the grounding stud. A first connection hole is opened on the copper backplate. The hull is provided with an assembly hole communicating the inside and outside of the hull. The grounding stud passes through the first connection hole and the assembly hole and extends outside the hull. The grounding copper plate is attached to the outside of the hull and is welded to one end of the grounding stud. The other end of the grounding stud is fixedly connected to the copper backplate through a grounding nut. The first connection hole and the assembly hole are filled with sealant.
[0006] In some embodiments of the present application, a first filling block is filled in the assembly hole, and the first filling block is provided with a through hole for the grounding stud to pass through.
[0007] In some embodiments of the present application, the first filling block is a fiberglass block.
[0008] In some embodiments of the present application, a reinforcing groove is provided on the inner side of the hull. A second connection hole is formed in the copper backplane. A connection stud passes through the second connection hole and is disposed in the reinforcing groove. The connection stud is fixedly connected to the copper backplane through a connection nut, and the reinforcing groove is filled with sealant.
[0009] In some embodiments of the present application, a second filling block is filled in the reinforcing groove. The second filling block is provided with a through hole for the connection stud to pass through.
[0010] In some embodiments of the present application, the second filling block is a fiberglass block.
[0011] In some embodiments of the present application, the thickness of the copper backplane is 6 mm.

The other end of the grounding stud 3 is fixedly connected to the copper backplane 2 through a grounding nut. The first connection hole 21 and the assembly hole 11 are filled with sealant 8.
[0023] Based on the above structure, before use, a grounding copper plate 4 is installed at an appropriate position below the waterline of the main hull. First, assembly holes 11 are set in the corresponding area, and then a copper backplane 2 is laid on the inner side of the hull 1. A grounding stud 3 connected to the grounding copper plate 4 passes through the hull 1 from the outside of the hull 1 along the assembly hole 11 and is inserted into the first connection hole 21 of the copper backplane 2. Then, sealant 8 is filled into the assembly hole 11 and the first connection hole 21 to block the assembly hole 11. Finally, a grounding nut is set to fix the grounding stud 3.
