Sealed mounting mechanism of ship cathode protection system

Abstract

The invention provides a sealed mounting mechanism of a ship cathode protection system, and relates to the field of ship corrosion prevention. The problems that defects still exist in the sealing effect, during sealing of the sealed mounting mechanism, only a single-layer sealing method can be adopted for sealing during sealing of the position of a cover plate, the operation of reducing water pressure and improving the sealing effect by reducing the pressed area cannot be achieved, the time consumed during fixing is long, and firmness is poor are solved. The sealed mounting mechanism of the ship cathode protection system comprises an anode bed; and the anode bed is of a hollow frame structure with the bottom being open, and an anode seat is fixedly connected in the anode bed through bolts.The structure of a sealing cover is improved, when the sealing cover is tightened, an annular rubber pad C is compressed, the top of the sealing cover is of a conic structure, and therefore comparedwith the application number CN201821494803.7., on one hand, the sealing effect can be further improved by the compressed annular rubber pad C, and on the other hand, the pressed area can be reduced bythe sealing cover of a columnar structure.

Description

technical field [0001] The invention belongs to the technical field of ship anticorrosion sealing assembly structure, and more specifically relates to a seal installation mechanism of a ship cathodic protection system. Background technique [0002] The hull and steel structure in the marine environment have serious electrochemical corrosion in the seawater medium, and certain corrosion protection measures need to be taken. Paint protection technology uses paint to form a film on the surface of the protected component to play a role in corrosion protection. It is an effective method of corrosion protection and is widely used. However, due to the influence of the integrity of the film-forming coating itself, such as coating defects, collision damage, aging, capillary penetration of the coating, etc., there is still a certain corrosion effect, which endangers the safety of the hull and steel structures, and affects the follow-up maintenance costs. Therefore, further additiona...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a seal installation mechanism of a marine cathodic protection system to solve one problem in the existing patented technology that the sealing effect still has defects. When the above application is sealed, on the one hand, when the position of the cover plate is sealed Only a single-layer sealing method can be used for sealing, and the effect is poor; on the other hand, the sealing structure is single, and the method of reducing the pressure area cannot be used to reduce the water flow pressure and improve the sealing effect; moreover, the fixing is convenient and firm. The above-mentioned applications and existing devices are mostly fixed by multiple bolts when they are installed and fixed, which takes a long time to fix and has poor firmness.
