DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, but they do not constitute a limitation of the present invention and are only used as examples to help those skilled in the art to more clearly understand the content and advantages of the present invention.

[0022] See also Figure 1-3An embodiment of the utility model provides an underwater flexible electrode cleaning device for a fish loading loss prevention and control system, comprising a cleaning block 2, a pull rope ring 3 fixed to the top of the cleaning block 2 and a counterweight ring 4 at the bottom of the cleaning block 2, a cleaning brush 6 fixed inside the cleaning block 2, and a clamp 8 for locking the cleaning block 2, and the pull rope ring 3 is used to connect with the pull rope 11.

[0023] There are two cleaning blocks 2, which are arranged in a symmetrical mutually coupled structure. The cleaning block 2 is a semi-cylindrical shape with a semi-conical bottom. After the two cleaning blocks 2 are combined, the main body is a cylinder with a cone at the bottom that can follow the water flow.

[0024] A semicircular limiting hole is provided at the top center of each cleaning block 2 . After the two cleaning blocks 2 are combined, the diameter of the flexible electrode limiting hole 5 formed by the combination of the two semicircular limiting holes is slightly larger than the diameter of the flexible electrode 1 .

[0025] Around the flexible electric limit hole 5 , four cleaning brush fixing screw holes 7 are arranged at the top center of the combined cleaning block, two of which are arranged for each cleaning block 2 , and the cleaning brush 6 is fixed to the cleaning brush fixing screw holes 7 .

[0026] like Figure 2 As shown, the cleaning brush 6 can be made of stainless steel, nylon or other materials with appropriate hardness according to the material of the flexible electrode 1 and the cleaning force requirements, and fixed in the center of the cleaning block 2. When the cleaning block 2 is assembled, the cleaning brush 6 forms a wrapping effect on the flexible electrode 1.

[0027] like Figure 3 As shown, two symmetrically coupled cleaning blocks 2 are connected together by upper and lower clamps 8 , and the clamps 8 are fixed by fasteners 9 .

[0028] The counterweight ring 4 can be equipped with a counterweight block on the original basis, which can ensure that when the friction is too large and the cleaning block cannot slide down by its own weight, the overall weight of the cleaning block is increased to achieve the purpose of sliding down at a uniform speed along the flexible electrode.

[0029] Please also read Figure 4 and Figure 5 The present utility model also provides a method for cleaning an underwater flexible electrode of a fish loading loss prevention and control system, which is carried out using the above-mentioned device. The method includes the following steps:

[0030] Step S1: Install the cleaning brush 6 to the cleaning brush fixing screw hole 7;

[0031] Specifically, an embedded design is adopted between two cleaning blocks 2, and a total of four cleaning brushes 6 are fixed on both sides of the inside of the cleaning block 2 in a symmetrical arrangement, and screws are passed through the cleaning brush fixing screw holes 7 to fix the cleaning brushes 6.

[0032] Step S2: Fix the traction rope to the pull rope ring 3;

[0033] Specifically, a traction rope 11 for binding the pull rope ring 3 is fixed to each of the two pull rope rings 3 on both sides of the top of the cleaning device.

[0034] Step S3: using the clamp 8 to symmetrically fix the cleaning block 2 to the flexible electrode 1;

[0035] Specifically, two cleaning blocks 2 are combined and symmetrically fixed to the flexible electrode 1 , and the cleaning blocks 2 are fixed at both ends by upper and lower clamps 8 through fasteners 9 .

[0036] Step S4: determining whether to add a counterweight according to the inclination of the flexible electrode 1;

[0037] Specific, combined Figure 3 According to the inclination angle of the flexible electrode 1 arrangement plan on site, an appropriate amount of counterweight blocks are installed at the counterweight ring 4 of the cleaning device, and the weight of the counterweight blocks is slowly increased step by step to achieve the effect of increasing the descending speed of the cleaning device and preventing the cleaning device from getting stuck when moving on the flexible electrode 1.

[0038] Step S5: repeatedly lifting or releasing the pull rope 11 to drive the cleaning device to slide along the flexible electrode 1 in the water by friction;

[0039] Specifically, along the arrangement direction of the flexible electrode 1, the pull rope 11 is manually pulled to lift the cleaning device so that it can be translated upward in a direction parallel to the flexible electrode 1; then the pull rope 11 is released, and the cleaning device slowly slides down in the water along the flexible electrode 1 under the action of its own weight and the counterweight. Repeated operations are performed to clean the flexible electrode with the help of friction and water flow.

[0040] Step S6: Unlock the clamp 8 and recycle the cleaning device or move to the next flexible electrode 1.

[0041] Specifically, loosen the clamp fastener 9, unfasten the clamp 8, and recycle the cleaning device; or move the cleaning device to the next flexible electrode 1, reassemble it, and carry out the cleaning operation.
