Description

Technical Field

[0001] The present invention belongs to the technical field of anti-fouling devices for seawater of surface ships, and particularly relates to an on-line replacement device and method for seawater anti-fouling electrodes. Background Art

[0002] When a ship operates in the marine environment for a long time, a large amount of marine organisms and other non-destructive conditions will occur on the sea pipeline. At present, electrolytic copper rods and other methods are usually used to generate copper ions for anti-fouling of marine organisms. Since the electrolytic copper rod is a consumable, the electrode needs to be replaced regularly. At present, when replacing the electrode, the equipment needs to be isolated, and then a new electrode is replaced. If the equipment is not isolated, seawater will overflow during the replacement process. Therefore, the electrode cannot be replaced during the operation of the equipment. A small amount uses a rubber one-way valve for sealing. Since the electrode rod needs to rub against the rubber one-way valve during the installation process, the rubber one-way valve is particularly prone to wear. After wear, the seal is not tight, resulting in a risk of seawater leakage. Summary of the Invention

In addition, it should be noted that only parts related to the present invention rather than all structures are shown in the drawings for the convenience of description.

[0023] A seawater anti-fouling electrode on-line replacement device provided in the technical solution of the present invention includes:

[0024] A sleeve structure is provided on the hull or the equipment body 1, and a circulation hole 7 is radially opened in the middle of the sleeve structure.

[0025] An electrode holder 4 is detachably arranged at the top opening of the sleeve structure, and an electrode rod 8 is fixed inside the sleeve structure through the electrode holder 4.

[0026] A movable sealing device 3 is movably arranged on the sleeve structure, and the circulation hole 7 on the sleeve structure can be blocked by moving the movable sealing device 3.

[0027] A top sealing device 5 is arranged between the sleeve structure and the electrode holder 4 to seal the connection surface between the sleeve structure and the electrode holder 4.

[0028] In an embodiment of the present invention, the sleeve structure includes a fixed sleeve 2 connected to the hull or the equipment body 1 and an electrode sleeve 6 arranged inside the fixed sleeve 2. Circulation holes 7 are radially opened at corresponding positions of the fixed sleeve 2 and the electrode sleeve 6.

[0029] In an embodiment of the present invention, the electrode sleeve 6 is used as the movable sealing device. The electrode sleeve 6 is slidably connected to the fixed sleeve 2, and the circulation hole 7 on the fixed sleeve 2 is blocked by sliding the electrode sleeve 6.

[0030] As a further optimization of the above embodiment, the movable sealing device 3 is a sealing cylindrical structure slidably sleeved outside the fixed sleeve 2. The circulation hole 7 on the fixed sleeve 2 is blocked by sliding the movable sealing device 3. The movable sealing device 3 can allow seawater to flow in and not flow into the electrode sleeve 6, realizing the online replacement of the electrode rod 8.

[0031] As Figure 1 shown, in an embodiment of the present invention, the fixed sleeve 2 is axially provided with a guide groove, the movable sealing device 3 is arranged in the guide groove, and the movable sealing device 3 can move up and down along the axial guide groove of the fixed sleeve 2. In this embodiment, the movable sealing device 3 includes a partition plate and an elastic diaphragm. A locking device is also arranged on the movable sealing device 3.

[0032] In the technical solution of the present invention, in addition to providing an on-line replacement device for seawater anti-pollution electrodes, a method for replacing seawater anti-pollution electrodes by using the above on-line replacement device for seawater anti-pollution electrodes is further provided.
