[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figures 1 to 4 This is the first embodiment of the present invention, which provides a technical solution: a wind turbine generator coolant circulation filtration device, comprising...

[0024] The filter box body 1 is connected to the wind turbine generator set 2 through two pipes 21, and the circulation pump 4 is installed on the top of the filter box body 1;

[0025] The filter box body 1 is equipped with a filter frame top plate 3. Two rectangular filter frames 31 are fixed on the bottom surface of the filter frame top plate 3. The two rectangular filter frames 31 are a magnetic filter element and a PP filter element, respectively. The magnetic filter element can directly remove iron oxide from the wastewater using a magnetic filter. The polypropylene PP filter element is also a commonly used filter element. It can effectively remove suspended solids, silt, rust and other impurities from the water. The top surface of the filter box body 1 has two rectangular slots 11 for the rectangular filter frames 31 to be inserted. In actual operation, the circulation pump 4 can draw the coolant inside the wind turbine generator 2 into the filter box body 1 through the pipe 21. The coolant is filtered out by the two rectangular filter frames 31 and then sent back to the inside of the wind turbine generator 2 through the pipe 21. This can filter out rust and other impurities in the coolant and reduce the waste of coolant. The model of the circulation pump 4 is KQDP25-2S.

[0026] And the limiting mechanism 5 set on both sides of the filter box body 1 includes a side seat 51 welded and fixed to the side of the filter box body 1, a cylindrical through hole 56 opened on the surface of the side seat 51, a cylindrical movable cylinder seat 57 movably installed at the bottom of the inner side of the cylindrical through hole 56, and a movable round rod 52 rotatably installed on the top of the cylindrical movable cylinder seat 57. The top end of the movable round rod 52 extends through to the top of the side seat 51 and is welded and fixed with a triangular pressure block 53. The triangular pressure block 53 presses on the top surface of the filter frame top plate 3, which can press and limit the filter frame top plate 3 to ensure the installation stability of the filter frame top plate 3. Afterwards, only the movable round rod 52 needs to be moved. By lifting and rotating the triangular pressure block 53 away from the top of the filter frame top plate 3, the pressure limit on the filter frame top plate 3 can be quickly released, allowing the filter frame top plate 3 to be lifted, which facilitates the subsequent disassembly and replacement of the rectangular filter frame 31. The limiting mechanism 5 also includes a side sliding groove 59 opened on the side wall of the cylindrical perforation 56. A side slider 58 and a spring 510 are provided in the side sliding groove 59. The side slider 58 slides in the side sliding groove 59, and one end of the side slider 58 is fixed to the cylindrical movable cylinder seat 57. Under the pushing of the spring 510, the triangular pressure block 53 can be stably pressed on the top of the filter frame top plate 3 for pressure limit during daily use.

[0027] In this embodiment, preferably, a strip-shaped guide block 54 is welded and fixed to one side surface of the movable round rod 52. A strip-shaped guide groove 55 corresponding to the strip-shaped guide block 54 is opened on the top surface of the side seat 51, and the strip-shaped guide groove 55 communicates with the top end of the cylindrical through hole 56. The bottom end of the strip-shaped guide block 54 is inserted into the strip-shaped guide groove 55. Under the limiting action of the strip-shaped guide block 54, the movable round rod 52 will not rotate on its own during daily use. If the filter frame top plate 3 and the rectangular filter frame 31 need to be removed later, first... Lift the movable rod 52, causing the cylindrical movable base 57 to move upward along with the side slider 58 and compress the spring 510 until the bottom end of the strip guide block 54 moves out of the strip guide groove 55, thus releasing the limit on the movable rod 52. At this point, the operator can rotate the movable rod 52, allowing the triangular pressure block 53 to rotate away from the top of the filter frame top plate 3. Once the triangular pressure block 53 is no longer blocking the filter frame, the filter frame top plate 3 can be lifted directly, allowing the rectangular filter frame 31 to be pulled out for maintenance and replacement.

[0028] In this embodiment, preferably, a top groove is provided on the inner wall of the top of the side sliding groove 59 for the spring 510 to be inserted, so that the top of the spring 510 can be limited after being inserted into the top groove to prevent deviation.

[0029] In this embodiment, preferably, a shaft is fixed to the bottom surface of the movable round rod 52, and the cylindrical movable sleeve 57 is rotatably sleeved on the shaft, so that the cylindrical movable sleeve 57 can be smoothly rotatably connected to the movable round rod 52.

[0030] In this embodiment, preferably, a lifting block is welded and fixed to the top surface of the movable round rod 52 to facilitate the subsequent lifting and rotation of the movable round rod 52 by the operator.

[0031] In this embodiment, preferably, a rectangular handle is welded and fixed to the top surface of the filter frame top plate 3 to facilitate the subsequent lifting of the filter frame top plate 3 by the operator.

[0032] Example 2

[0033] Please see Figures 1 to 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that a U-shaped sealing ring 32 is also installed on the bottom surface of the filter frame top plate 3, and the two rectangular filter frames 31 are located inside the U-shaped sealing ring 32. A U-shaped sealing groove 12 corresponding to the U-shaped sealing ring 32 is opened on the top surface of the filter box body 1, and the U-shaped sealing ring 32 is embedded in the U-shaped sealing groove 12. The U-shaped sealing ring 32 is made of rubber material, which can play a certain sealing effect and prevent coolant leakage.

[0034] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
