Description

Technical Field

[0002] Offshore wind power generation technology mainly utilizes the abundant wind energy resources in the ocean and converts wind energy into electrical energy through wind turbines, and has huge development potential.

[0003] Auxiliary anodes for offshore wind power generation are key components in impressed current cathodic protection systems, primarily used to prevent corrosion of wind turbine foundation structures. Existing auxiliary anode structures consist of an anode body and a shell surrounding the anode body. The anode body is centrally located within the shell and connected to a power cable at one end. During installation, to ensure centering, a positioning block is required within the shell to secure the anode body. Traditional positioning blocks are mostly made of carbon steel and welded to the inner wall of the shell. Since the shell is typically made of 80-gauge pipe with a small diameter, welding is difficult.

[0004] In addition, an insulating pad is required on the carbon steel positioning block to ensure effective insulation between the anode body and the positioning block, which greatly increases the difficulty of assembly; and if the assembly is poor, insulation damage is likely to occur, affecting the use effect.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0024] Reference Figure 1As shown, an embodiment of the internal structure of a marine anti-corrosion auxiliary anode of the present invention includes a shell 1 and an anode body 2 arranged in the shell. Insulation positioning blocks 3 are provided at both ends of the anode body. An annular groove is provided on the outer periphery of the insulation positioning block. A sealing ring 4 is provided in the annular groove. The sealing ring is used to seal and fix the insulation positioning block inside the shell. A flow hole 5 is provided on the shell surface corresponding to the anode body. The flow hole can be elliptical to effectively increase the flow area. A glue cavity is formed between the insulation positioning block and the end of the shell. The glue cavity is filled with a first sealant 7. A plastic spray layer is provided on the surface of the shell to play an anti-corrosion role. A flange 13 is provided on the shell for fixed installation during use.

[0025] During assembly, first install the sealing ring in the annular groove of the insulating positioning block, and then fix the insulating positioning block to the two ends of the anode body. Specifically, pass the screws at both ends of the anode body through the through holes on the insulating positioning block, and then lock it with a lock nut. After fixing, insert the whole into the shell directly and force it to the specified position. The sealing ring deforms during the insertion process, so that the insulating positioning block is tightened in the shell, but not completely fixed, so it can be pushed with force. While playing a fixing role, the sealing ring also fills the gap between the insulating positioning block and the shell, playing a sealing role. Subsequently, the first sealant is poured into the two glue cavities at both ends, and the whole is formed after solidification.

[0026] Among them, a wiring nose 11 is provided on the threaded rod at the head end of the anode body, and one end of the wiring nose needs to extend out of the shell. In order to ensure the stability of the connection, an end cover 10 is provided on the top of the glue filling cavity on the head end side of the anode body. The end cover is used to fix the wiring nose, and the end cover is fixed to one side of the shell end by the first sealant.

[0027] A step hole 8 is provided in the middle of the above-mentioned insulating positioning block, and the inner wall of the step hole can cooperate with the outer wall of the anode body to form an effective positioning effect. The insulating positioning block is sleeved on the end of the anode body through the step hole and locked by a nut. In order to ensure a better sealing effect, a glue storage tank 9 is provided in the step hole of the insulating positioning block, and a second sealant 6 is provided in the glue storage tank. When the insulating positioning block is fixed to the anode body, the second sealant fills the gap between the two and also plays a connecting effect after curing.

[0028] In one embodiment, a positioning protrusion may be provided on the inner wall of the glue potting cavity at one side of the tail end of the anode body to determine the position of the anode body after it is inserted into the shell.

[0029] Specifically, the positioning protrusion is a metal positioning bar 12, which is welded and fixed on the inner wall of the glue filling cavity. The number of metal positioning bars can be 2, which are symmetrically distributed. When welding and fixing, it is only necessary to perform spot welding at a position that is convenient for welding. The operation is convenient. The set length of the metal positioning bar can locate the position of the anode body after installation, and there is no need to use experience to judge whether it is installed in place.

[0030] In one embodiment, the positioning protrusion can also be designed as an external threaded ring, which is threadedly connected to the inner wall of the glue filling cavity. The screwing method is easy to operate and can also meet the positioning effect.

[0031] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by those skilled in the art based on the present invention shall fall within the protection scope of the present invention.
