Problems solved by technology
[0002] At present, with the development of the offshore oil industry, offshore oil development has gradually moved from near-shore shallow water to deep water. Under deep water conditions, underwater facilities are difficult to maintain, and severe corrosion will cause failure of underwater products and systems.
Under deep water conditions, the anti-corrosion measures of underwater facilities are mainly the combined anti-corrosion method of coating and sacrificial anode cathodic protection, but this anti-corrosion measure cannot be controlled

Embodiment Construction
[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.
[0025] Such as figure 1 , figure 2 and Figure 6 As shown, an external anode protection device for underwater facilities is used to supplement the original anode (not shown in the figure) consumed underwater by connecting the underwater steel structure, including a spare anode 1, a conductive male connector 2, and a female connector 3 One end of the joint female head 3 is connected to the underwater steel structure, and the other end of the joint female head 3 is provided with an engaging groove 31. The joint male head 2 includes a pivotal connection part 21 and an engaging part 22 connected to each other. The engaging part 22 Adapted to the engaging groove 31 , the pivotal con...

The invention discloses an external anode protection device for an underwater facility. An underwater consumed original anode is supplemented by being connected with an underwater steel structure. Thedevice comprises a conductive joint male part, a joint female part and a standby anode. One end of the joint female part is connected with the underwater steel structure, and the other end of the joint female part is provided with a clamping groove. The joint male part comprises a pivot connection part and a clamping part which are connected with each other, the clamping part is matched with theclamping groove, and the pivot connection part is connected with the standby anode used for consumption through a cable. Under the condition that corrosion prevention of the underwater facility failsdue to coating failures, excessively quick cathodic protection anode consuming and other reasons, the standby anode is provided for continuing cathodic protection of the underwater facility, the maintenance cost of an underwater cathodic protection system is reduced, and the integrity and stability of an underwater production system are guaranteed.
Description
technical field [0001] The invention relates to the technical field, in particular to an external anode protection device for underwater facilities. Background technique [0002] At present, with the development of the offshore oil industry, offshore oil development has gradually moved from near-shore shallow water to deep water. Under deep water conditions, underwater facilities are difficult to maintain, and severe corrosion will cause failure of underwater products and systems. Under deep water conditions, the anti-corrosion measures of underwater facilities are mainly the combined anti-corrosion method of coating and sacrificial anode cathodic protection, but this anti-corrosion measure cannot be controlled. In order to prevent corrosion failure caused by coating failure and cathodic protection anode consumption too fast, etc., the electrical connection interface can be reserved in the design of underwater facilities, and the quick electrical connector can be used to con...
