Description

[0002] A wind turbine is a device that converts wind energy into electrical energy. It is mainly composed of blades, generators, mechanical components and electrical components. Before maintaining and inspecting the wind turbine, the main shaft needs to be stopped and the high-speed shaft brake disc is usually rotated manually. This operation of rotating the high-speed shaft brake disc is called "cranking". As the capacity of a single machine continues to increase, the cranking resistance increases, and manual cranking is more laborious.

[0003] At present, the high-speed shaft brake disc is made into an external meshing gear, and an external meshing pinion is used to make the driving motor drive the high-speed brake disc to rotate, thereby driving the impeller to rotate.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] Embodiment 1 further describes an electric winch device for a direct-drive wind turbine generator proposed by the present invention, including a wind turbine generator set 100, a brake disc 101 fixedly connected to the main shaft of the wind turbine generator set 100, a sleeve 102 fixedly connected to the brake disc 101, the sleeve 102 surrounds the main shaft of the wind turbine generator set 100, mounting frames 103 fixedly connected to both sides of the outer wall of the sleeve 102, geared discs 104 are arranged in the mounting frames 103 on both sides, the geared discs 104 include a geared disc 105 and a geared disc 2 106, a locking mechanism 300 is arranged in the mounting frame 103, a positioning mechanism 400 is arranged on the geared disc 105 and the geared disc 2 106, a driving mechanism 200 is arranged on the outer wall of the wind turbine generator set 100, a pinion 107 is arranged in the driving mechanism 200, and the pinion 107 is meshed with the geared disc 105 and the geared disc 2 106 correspondingly;

[0036] The prior art installs a gear plate on the brake disc 101, and drives the gear plate on the brake disc 101 to rotate through a motor, thereby driving the impeller to rotate. However, this method usually requires the coupling connected between the brake disc 101 and the generator to be removed before the gear plate can be coaxially installed on the brake disc 101.

[0037] The present invention further improves the prior art by fixing an installation frame 103 on both sides of the outer wall of the brake disc 101, wherein a sprocket 105 and a sprocket 2 106 are installed in the installation frame 103, and the sprocket 105 and the sprocket 2 106 have the same structure and correspond to each other. The sprocket 105 and the sprocket 2 106 are quickly locked by the internal structure of the installation frame 103, so that the sprocket 105 and the sprocket 2 106 form an integral structure, and a driving mechanism 200 and a pinion 107 are provided on the side of the sprocket member 104, and the pinion 107 is correspondingly meshed with the sprocket 105 and the sprocket 2 106. Therefore, when the driving mechanism 200 drives the pinion 107 to rotate, the sprocket member 104 rotates synchronously, and the cranking operation can be performed at this time, so that there is no need to remove the coupling between the brake disc 101 and the driving end of the generator, thereby greatly improving the work efficiency.

[0038] The driving mechanism 200 includes a supporting member 201 disposed on the wind turbine generator set 100, a sliding member 202 is disposed in the supporting member 201, a driving member 203 is disposed in the sliding member 202, a cleaning mechanism 500 is disposed at the bottom of the supporting member 201, a locking mechanism 300 includes an abutting member 301 disposed in the mounting frame 103, a separating member 302 is disposed in the mounting frame 103, an elastic member 303 is disposed in the separating member 302, a fixing member 304 is further disposed on the separating member 302, and an auxiliary member 305 cooperating with the fixing member 304 is disposed in the toothed disc 1 105 and the toothed disc 2 106;

[0039] Depend on Figures 1 to 4 It can be known that the present invention fixes a support member 201 on the outer wall of the wind turbine generator set 100 by bolts, a sliding member 202 is arranged in the support member 201, and a driving member 203 is arranged in the sliding member 202, so that the position of the driving member 203 can be adjusted, so that the wind turbine generator set 100 of the device will not produce motion interference with the driving mechanism 200 when in normal use, and the present invention further refines the structure of the support member 201, and a cleaning mechanism 500 is arranged at the bottom of the support member 201. When the driving member 203 is in operation, the cleaning mechanism 500 processes the waste oil on the surface of the brake disc 101 to remove the oil stains and other impurities on the outside of the brake disc 101;

[0040] The positioning mechanism 400 includes an inserting member 401 disposed on the first toothed disc 105, a positioning member 402 matching the inserting member 401 is disposed on the second toothed disc 106, an unlocking member 403 is disposed on the outer wall of the positioning member 402, the inserting member 401 and the positioning member 402 are in conflict with each other, and the unlocking member 403 releases the conflicting state between the inserting member 401 and the positioning member 402;

[0041] The present invention further simplifies the installation method of the toothed disc 105 and the toothed disc 2 106. The positioning mechanism 400 is used to preliminarily position the positions of the toothed disc 105 and the toothed disc 2 106. Specifically, the device is positioned by the cooperation of the inserting member 401 and the positioning member 402, so that the staff has better stability during installation. Then, the locking mechanism 300 is used to completely lock the toothed disc 105 and the toothed disc 2 106. The displacement of the bolt in the vertical direction drives the abutting member 301 to squeeze the separating member 302, and the separating member 302 drives the fixing member 304 to cooperate with the auxiliary member 305, so as to realize the overall fixing of the toothed disc 105 and the toothed disc 2 106. This not only improves the installation efficiency, but also ensures the stability of the toothed disc member 104.

[0042] The cleaning mechanism 500 includes a movable member 501 disposed in the support member 201, an extrusion member 502 is disposed on one side of the sliding member 202, a cleaning member 503 is disposed in the movable member 501, and the movable member 501 and the extrusion member 502 cooperate to enable the cleaning member 503 to clean the outer wall of the brake disc 101;

[0043] Depend on Figures 2 to 5 It can be seen that a movable part 501 that can move in the vertical direction is provided in the support part 201, and a cleaning part 503 is provided on one side of the sliding part 202. When the pinion 107 in the driving mechanism 200 is engaged with the gear plate 105 and the gear plate 2 106, the extrusion part 502 on the side wall of the sliding part 202 abuts against the movable part 501, so that the movable part 501 and the extrusion part 502 cooperate to enable the cleaning part 503 to clean the outer wall of the brake disc 101.

[0044] Working principle: When the device is used, firstly, the toothed disc 105 and the toothed disc 2 106 are installed, and the toothed disc 104 is fixed by the positioning mechanism 400 and the locking mechanism 300, so that the toothed disc 105 and the toothed disc 2 106 form a complete gear structure, and then the driving member 203 in the sliding member 202 is moved, so that the pinion 107 is meshed with the toothed disc 104, and at the same time, the extruding member 502 on the side wall of the sliding member 202 abuts against the movable member 501, so that the bottom end of the cleaning member 503 contacts the surface of the brake disc 101, and then Start the driving member 203 to rotate the pinion 107. Since the pinion 107 engages the toothed disc member 104, the brake disc 101 in the toothed disc member 104 is driven to rotate, so that the cranking operation can be performed. When the brake disc 101 rotates, the cleaning member 503 cleans the outer surface of the brake disc 101, thereby removing oil and other impurities on the outside of the brake disc 101. In summary, the device can realize the rapid installation of the toothed disc member 104 without removing the coupling, thereby driving the brake disc 101 to rotate, thereby improving work efficiency.
