Auxiliary anode structure for water environment

Technical Field

The utility model relates to the technical field of cathode protection devices of underwater metal structures, in particular to an auxiliary anode structure for a water environment.

Background

Cathodic protection is the most economical and effective corrosion control measure for buried pipelines and underground metal structures. The cathodic protection technology is a corrosion control method for preventing an underground metal structure from being corroded by reducing corrosion potential of the metal structure in soil and even leading the corrosion current to be zero by introducing a sufficient amount of direct cathodic current to the underground metal structure to be protected and carrying out cathodic polarization on the outer surface of the metal structure. The cathodic protection technology is divided into two technical methods, namely sacrificial anode cathodic protection and impressed current cathodic protection, according to the source of direct current. An important component of impressed current cathodic protection systems is the auxiliary anode, which functions to transfer the protective current through the medium to the surface of the structure being protected.

In order to avoid the anode breakage, a high-strength nylon rope is usually laid in parallel to protect and fix the tubular anode, which results in the difficulty of operation of the whole project, and the technical scheme is similar to the utility model with the application number of "92885968.9".

Still there is a technical scheme among the prior art, like the utility model patent of application number "201720179484. X", the name is "metal structure cathodic protection device under water seal airtight environment", the material of supplementary positive pole adopts the positive pole wire among this technical scheme, compare in bar-shaped positive pole, be difficult to produce the fracture, the practicality is stronger, its concrete technical scheme is fixed cable and positive pole wire, then sets up inside an insulation housing, forms a cathodic protection device with insulation housing protection device. However, in the manufacturing process, the anode metal wire needs to be fixed on the cable first, and then the cable and the anode metal wire are integrally fixed inside the insulating shell, so that the manufacturing process is slightly complicated; because it fixes the cable in insulating housing, insulating housing need guarantee still to be longer than the cable, and whole supplementary positive pole structure is more complicated, and laying process cable and positive pole metal wire can receive the restriction of other side moreover, and the construction degree of difficulty is bigger.

Therefore, the auxiliary anode structure which is simpler in structure and lower in construction difficulty is provided, and has important significance in protecting underwater metal parts.

In the embodiment, the insulating tube 2 is only provided with the anode metal wire 1 and is connected with the anode metal wire 1 at intervals, so that the integral structure is simpler and the manufacture is more convenient; moreover, compared with the prior art, the auxiliary anode structure in the embodiment is connected with the cable 4 during construction, so that during construction, the cable 4 and the insulating tube 2 can be constructed independently without influencing each other, and the using amount of the insulating tube 2 can be reduced correspondingly; and the anode metal wire 1 and the cable 4 are electrically connected to be used, so that the construction is more convenient. In addition, the auxiliary anode material in this embodiment is a metal wire with a smaller diameter, which has better toughness and is not easily broken, so that the construction scheme has more options and the construction difficulty is further reduced.

The connection method of the anode wire 1 and the cable 2 is well known to those skilled in the art, and thus the specific connection method and the structure of the connector 3 at the end of the anode wire 1 are not particularly limited in this embodiment.

In the embodiment, the inner diameter of the insulating tube 2 is larger than that of the anode metal wire 1, and a certain interval is left between the inner wall of the insulating tube 2 and the side wall of the anode metal wire 1, so that water can conveniently flow into the insulating tube 2 to carry out potential transmission; therefore, the discharge channel in this embodiment includes a plurality of through holes 5 formed in the wall of the insulating tube 2, and also includes the space between the insulating tube 2 and the anode wire 1; the purpose of arranging the through holes 5 on the insulating tube 2 is to further facilitate the uniform distribution of the liquid medium in the water environment around the anode metal wire 1, so that the current during working is timely dissipated to the surrounding environment, and the anode metal wire 1 is ensured to have a good cathode protection effect.
