A self-peeling nail fastening system protection device for ships

Abstract

The invention discloses a self-peeling type marine nail fastening system protection device, belonging to the field of nailing fastening devices, and a self-peeling marine nailing fastening system protection device. Under the action of the corrosion source, the shell is partially corroded and penetrated to form through holes, and a plurality of three-dimensional helical fibers in the filling cavity will be extruded from the through holes. The pollution source further corrodes the anti-corrosion rubber shell. On the other hand, a protective layer of a three-dimensional space structure formed by a plurality of three-dimensional helical fibers is formed at the penetration point, which is not prone to excessive corrosion. As the number of exposed three-dimensional helical fibers increases , the tension caused by the sea breeze will also increase, so that the outermost peeling part and the connecting part are easily separated from the protective structure, so that the corrosion source is separated from the protective structure, and excessive corrosion is not easy to occur, prolonging the protection structure. service life.

Description

technical field [0001] The invention relates to the field of nail fastening devices, in particular to a self-peeling nail fastening system protection device for ships. Background technique [0002] Nail shooting refers to the use of gunpowder gas generated by firing empty shells as power to drive a nail into a building. It usually consists of a nail plus a gear ring or a plastic positioning collar. The role of the gear ring and the plastic positioning collar is to hold the nail The body of the nail gun is fixed in the barrel of the nail gun to avoid sideways deviation when firing. The function of the nail is to drive the nail into the matrix such as concrete or steel plate to fasten the connection. [0003] As a construction device, nails are widely used in various construction fields. For different targets, nails usually need to be improved accordingly. The most important consideration for marine nails is sea water. Corrosion, because seawater is rich in various ions, its ...

AI Technical Summary

Problems solved by technology

[0004] Existing anti-corrosion methods mainly include coating anti-corrosion paint and electrochemical anti-corrosion. Among them, anti-corrosion paint mainly uses paint to coat the hull and key parts to isolate it from contact with seawater and air. To achieve the purpose of anti-corrosion, while electrochemical anti-corrosion is to connect the active metal block for the hull and other targets, and transfer the corrosion of the hull and other targets to the active metal block, thereby achieving the purpose of anti-corrosion, and for nailing , the main anti-corrosion method is to apply anti-corrosion paint. However, the anti-corrosion paint will be worn out during use, and the nail will be exposed. Once the corrosive substance adheres to the nail, it is easy to cause continuous damage to the nail. Sexual corrosion affects the fastening effect of the nail
