Embodiment 1

[0037] Such as Figure 1~6 As shown, the device provided by this embodiment to facilitate the replacement of underwater auxiliary anodes includes a waterproof cable 1, a lifting mechanism for lifting the waterproof cable 1 and several anodes 2, wherein the anodes 2 are spaced apart and detachable It is fixed on the waterproof cable 1 and electrically connected to the internal wires of the waterproof cable 1, and the waterproof cable 1 is detachably fixed on the lifting end of the lifting mechanism.

[0038] Such as figure 1 As shown, the description of the specific structure of the device that facilitates the replacement of the underwater auxiliary anode is carried out below:

[0039] The anode 2 is used as a protective electrode of the steel structure in the shaft to protect the steel structure from corrosion; the waterproof cable 1 is used to fix the anode 2, and connect the power supply to the anode 2 so that the current passes through the anode The surface of 2 flows int...

Embodiment 2

[0073] The difference between this embodiment and the first embodiment is that this embodiment provides a replacement method for the anode 2 .

Abstract

The invention belongs to the technical field of anti-corrosion of underwater steel components, and discloses a device and a replacement method for facilitating the replacement of underwater auxiliary anodes. Among them, a device for facilitating the replacement of underwater auxiliary anodes includes a waterproof cable, a waterproof cable for lifting The lifting mechanism and several anodes, wherein, the anodes are spaced and detachably fixed on the waterproof cable, and are electrically connected to the internal wires of the waterproof cable, and the waterproof cable is detachably fixed on the lifting The lifting end of the mechanism. The invention has the advantages of convenient anode replacement and convenient maintenance.

Description

technical field [0001] The invention relates to the technical field of anticorrosion of underwater steel components, in particular to a device and a replacement method for facilitating the replacement of auxiliary anodes. Background technique [0002] In the construction of underground oil storage depots, the service life of the steel structures in the underground oil storage depot's inlet and outlet shafts is generally more than 60 years. Because the inlet and outlet shafts are very deep, often reaching 100m or even 200m, so the steel structures in the shaft Corrosion protection has very high demands. [0003] At present, the anticorrosion of steel buildings generally adopts sacrificial anode cathodic protection method and forced current cathodic protection method, but because the sacrificial anode cathodic protection method can not protect the steel structures in the shaft for the required number of years, so, In the existing shaft, the forced current cathodic protection ...
