The load of the lifting lug 13 can reach 90 kg, and the materials of the lifting lug 13 can include but not be limited to galvanized carbon steel.

[0041] Combined with Figures 3 to 6, in some embodiments, the anode 22 includes a housing 221, which is mounted on the anode shielding plate 21, and a through hole 2211 is provided on the side of the housing 221 opposite to the anode shielding plate 21. An anode working plate 222 is provided inside the housing 221, and the anode working plate 222 is disposed opposite to the through hole 2211. The housing 221 may be generally in a rectangular columnar structure, the through hole 2211 is generally rectangular, and the size of the through hole 2211 is smaller than the size of the anode working plate 222. The anode working plate 222 may be welded inside the housing 221 or fixed by screws or bolts, etc. The housing 221 may be made of polyvinyl chloride. The anode working plate 222 may be an MMO plate or a platinum-plated anode on a titanium substrate. The maximum current output of the MMO plate can be 36.3A.

[0042] Further, the anode 22 further includes a cable 224 connected to the anode working plate 222, and the cable 224 extends out of the housing 221. One end of the cable 224 is connected to the anode working plate 222 through an electrical connection fastener 225. Connection columns or bolts may be provided on the anode working plate 222, and the electrical connection fastener 225 may include nuts, etc. One end of the cable 224 is connected to the connection column or bolt of the anode working plate 222 through a nut. The end of the cable 224 far from the anode working plate 222 is connected to a common wire groove for conducting electricity.

[0043] In some embodiments, the housing 221 is filled with an insulating filler 223, which may include but is not limited to epoxy resin. The insulating filler 223 fills and solidifies the housing 221. In addition to providing waterproof protection for the electrical connection fastener 225, the anode working plate 222 is tightly pressed against the inner surface of the housing 221 to control the anode working surface area.

[0044] As Figure 3 shown, in some embodiments, one end of the housing 221 is connected with a protection tube 226, the protection tube 226 is communicated with the inner cavity of the housing 221, and the cable 224 is disposed through the protection tube 226.

It can be understood that by providing the limiting plate 17 and the clamp 18, the situation of damage caused by the anode root cable shaking due to wind and waves can be avoided.

[0045] Understandably, the steel pipe pile anode device can install the anode assembly 20 on the first steel pipe pile 100 through the installation assembly 10. The tension ropes 40 (which can be two tension ropes 40 on the left and right) are used to increase the firmness of the anode assembly 20 and reduce the stress on the installation assembly 10 at the same time. Through the combination of the installation assembly 10 and the tension ropes 40, the whole steel pipe pile anode device increases the firmness of the installation of the anode assembly 20 and the durability against wind and wave impacts, and also greatly simplifies the fixing structure of the anode assembly 20, significantly reducing the amount of welding work and installation. The use of the anode shielding plate 21 realizes the pre-assembly of the anode 22, and at the same time avoids the influence of the over-negative protection potential of the steel pipe pile near the anode 22, achieving the cathodic protection effect of the underwater steel pipe pile.

[0046] Understandably, the steel pipe pile anode device is simpler in structure and the cost is greatly reduced. The components of the anode assembly 20 can be pre-assembled, reducing the amount of work at the construction site and the complex auxiliary components on the steel pipe pile. Therefore, while the economy is improved, there are no safety risks and impacts on the surrounding facilities of the nuclear power plant.
