Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3 The utility model provides a new technical solution: a quick-connect wind power slip ring, comprising a wind power slip ring 1 and a brush signal connection terminal 3, a connection sleeve 2 is fixedly connected to the brush signal connection terminal 3, a quick connection component is arranged on the connection sleeve 2, the quick connection component is evenly arranged in a circular array, and is used for locking the wind power slip ring 1 and the brush signal connection terminal 3, and the quick connection component comprises a push ring 11, an inclined top block 15, a top block spring 16 and a clamping block 17;

[0025] A connection locking assembly is provided on the connection sleeve 2, and the connection locking assembly is used for rotational connection between the wind power slip ring 1 and the brush signal connection end 3. The connection locking assembly is evenly arranged in a circular array, and the connection locking assembly includes a rotating plate 7, a pulley shaft 9, two pulleys 10 and two pulley springs 12;

[0026] The connection locking assembly also includes a fixed seat 6, a rotating plate 7 is rotatably connected in the fixed seat 6, a fixed frame 8 is fixedly connected to the outer surface of the rotating plate 7, a pulley shaft 9 is fixedly connected in the fixed frame 8, and two pulleys 10 are sleeved on the outer surface of the pulley shaft 9;

[0027] The two pulley springs 12 are both sleeved on the outer surface of the pulley shaft 9, and the two pulley springs 12 are respectively located between the corresponding pulley 10 and the vertical plate of the fixed frame 8. One end of the wind turbine slip ring 1 is fixedly connected to the transmission shaft 4, and the outer surface of the transmission shaft 4 is provided with two V-shaped fixing grooves 5 adapted to the pulley 10.

[0028] Furthermore, the clamping block 17 in the connection and locking assembly is fixedly connected to the outer surface of the fixing frame 8 , and the end surface of the wind power slip ring 1 is provided with a first movable groove 13 corresponding to the clamping block 17 .

[0029] Furthermore, a spring groove 14 is provided in the first movable groove 13 , a tilted lift block 15 is slidably connected in the spring groove 14 , the tilted lift block 15 is adapted to the clamping block 17 , and a lift block spring 16 is arranged between the tilted lift block 15 and the bottom wall of the spring groove 14 .

[0030] Furthermore, a protrusion is integrally formed on the inclined lift block 15, and the protrusion extends out of the outer surface of the wind turbine slip ring 1. The outer surface sliding sleeve of the wind turbine slip ring 1 is provided with a push ring 11, and the push ring 11 is fixedly connected to the protrusion of the inclined lift block 15 in the quick connection assembly.

[0031] Furthermore, the outer surface of the transmission shaft 4 is provided with a brush slot 18 for transmitting signals, and the brush signal connection terminal 3 is provided with a brush matching the brush slot 18 .

[0032] Furthermore, when in use, the connecting sleeve 2 is manually sleeved on the transmission shaft 4, and the fixing frame 8 is rotated at this time. The fixing frame 8 can drive the components carried on the pulley shaft 9 to rotate together until the block 17 on the fixing frame 8 can enter the first movable groove 13. The block 17 entering the first movable groove 13 will apply a force to the inclined surface of the inclined top block 15, so that the inclined top block 15 can compress and deform the top block spring 16 until the block 17 is separated from the inclined top block 15 and the inclined top block 15 pops up. At this time, the inclined top block 15 limits the position of the block 17, and when the block 17 completes the locking, the pulley 10 in the connection locking assembly can adapt to the corresponding V-shaped fixing groove 5. In this adaptation process, the two pulleys 10 will drive the corresponding pulley spring 12 to compress and deform, so that The pulley 10 is located exactly in the center of the inner wall of the V-shaped fixed groove 5. At this time, the brush on the brush signal connection terminal 3 will adapt to the brush groove 18 to complete the installation and connection of the wind power slip ring. This avoids the traditional installation method that requires multiple screws, bolts or other fasteners to fix the connecting parts, which is time-consuming and labor-intensive, and is also prone to unstable or damaged connections due to improper fastening. This design simplifies the installation process and improves the installation efficiency through a simple rotation and automatic locking mechanism. After the card block 17 enters the first movable groove 13, the pulley 10 is automatically and accurately positioned in the center of the inner wall of the V-shaped fixed groove 5 through the interaction of the inclined top block 15 and the top block spring 16, ensuring the accurate adaptation of the brush signal connection terminal 3 and the brush groove 18, and improving the stability and reliability of the connection.

[0033] Furthermore, when disassembly is required, it is only necessary to push the push ring 11 backwards. The push ring 11 can drive the inclined top block 15 to retract backwards through the protrusion of the inclined top block 15 in the quick connection assembly, until the block 17 can break away from the restriction of the inclined top block 15, so that the brush slot 18 can be indirectly rotated out. At this time, the wind turbine slip ring 1 and the brush signal connection terminal 3 can be quickly disassembled, avoiding the need to loosen multiple fasteners one by one during the disassembly process in the traditional way, which is cumbersome and time-consuming. This design can quickly release the locking mechanism by pushing the push ring 11, so that the connecting parts can be easily separated, which greatly simplifies the disassembly process. The quick disassembly design allows rapid replacement or maintenance of components such as the brush signal connection terminal 3, reduces downtime, and improves the maintenance efficiency and convenience of the equipment.

[0034] Working principle: When in use, the connecting sleeve 2 is manually mounted on the transmission shaft 4, and the fixing frame 8 is rotated at this time. The fixing frame 8 can drive the components carried on the pulley shaft 9 to rotate together until the block 17 on the fixing frame 8 can enter the first movable groove 13. The block 17 entering the first movable groove 13 will apply a force to the inclined surface of the inclined top block 15, so that the inclined top block 15 can compress and deform the top block spring 16 until the block 17 is separated from the inclined top block 15 and the inclined top block 15 pops out. At this time, the inclined top block 15 limits the position of the block 17, and when the block 17 completes the locking, the pulley 10 in the connection locking assembly can be adapted to the corresponding V-shaped fixed groove 5. In this adaptation process, the two pulleys 10 will drive the corresponding pulley spring 12 to compress and deform, so that the pulley 10 can be located just in the center of the inner wall of the V-shaped fixed groove 5. At this time, the brush on the brush signal connection terminal 3 will adapt to the brush groove 18 to complete the installation and connection of the wind power slip ring.

[0035] Furthermore, when disassembly is required, the push ring 11 only needs to be pushed backwards. The push ring 11 can drive the inclined top block 15 to retract backwards through the protrusion of the inclined top block 15 in the quick connection assembly, until the clamping block 17 can be freed from the restriction of the inclined top block 15, so that the brush slot 18 can be indirectly rotated out. At this time, the wind turbine slip ring 1 and the brush signal connection terminal 3 can be quickly disassembled.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
