Description

Technical Field

[0001] The invention relates to the technical field of wind power generation equipment, in particular to self-locking wind power generation hydraulic equipment. Background Art

[0002] In the field of wind power generation, the performance of wind power hydraulic equipment is directly related to the power generation efficiency and the safety and stability of equipment operation. Currently, this type of equipment faces many challenges in braking and pressure control. It is difficult for existing wind power hydraulic equipment to achieve reliable self-locking function during braking, which makes the internal pressure of the hydraulic equipment easily fluctuate. Therefore, when the shaft of the wind power generation equipment stalls due to factors such as strong winds, it is difficult for traditional braking devices to stably and effectively apply uniform braking force, resulting in safety hazards for the equipment. Traditional equipment is also more prone to pressure leakage during braking. At this time, the pressure drop of the hydraulic equipment not only reduces the braking effect, but may also cause the equipment to lose control and cause accidents. Due to the lack of a reasonable pressure limiting mechanism, during continuous braking, the hydraulic equipment without a locking structure will be subjected to excessive hydraulic oil pressure, which is likely to cause damage to the internal components of the hydraulic equipment, and then oil leakage will occur. This not only increases the maintenance cost of the equipment, but also affects the power generation efficiency due to failure shutdown, restricting the development of the wind power industry.

The rolling groove 113 is arranged on the outer wall of the wrapping tube 111, and cooperates with the rolling wheel 34 of the shock absorbing device 3, which is conducive to the smooth rotation and shock absorption of the equipment during operation. The connecting device 1 provides a stable power input foundation for the whole equipment, ensuring that the rotating shaft of the wind power generation equipment can accurately transmit power to the subsequent device. The outer shell device 12 provides protection and support for the internal device.

When the shaft stalls and needs to be braked, the pushing ring 23 squeezes the brake disc 112 to achieve preliminary braking. At the same time, the linkage device 26 is driven by squeezing the pushing ring 23 to enter the interior of the limit device 22 to achieve the braking process. The pushing rod 261 moves under the drive of the pushing ring 23. During the movement of the pushing rod 261, the compression spring 262 provides elastic force for the locking block 263. When the locking block 263 moves to the pipeline position where the magnetic ring 224 is located, the locking block 263 will pop out under the action of the compression spring 262, enter the position of the inclined slide bar 225 and contact the inclined slide bar 225, and push the top of the inclined slide bar 225 out of the fixed tube 221, so that the locking block 263 is engaged in the fixed tube 221, thereby realizing the self-locking operation of the equipment.

[0036] The side wall inside the connecting sleeve 121 is rotatably connected to the outer wall of the wrapping tube 111, the side wall inside the limiting ring 123 is fixedly connected to the outer wall of the connecting sleeve 121, the outer wall of the sliding protrusion 266 is fixedly connected to the outer wall of the limiting rod 27, the outer wall of the pushing ring 23 is fixedly connected to the outer wall of the pushing rod 261, the inner wall of the positioning block 21 is fixedly connected to the outer wall of the protective tube 122, and the sealing block 264 is pushed toward the direction of the limiting tube 222, thereby driving the limiting rod 27 to move. In actual use, in the fixed tube 221, the space surrounded by the limiting tube 222, the sliding protrusion 266 and the sliding sleeve 258 is filled with hydraulic oil. Since the position of the limiting tube 222 is fixed, when the limiting rod 27 moves, it will squeeze the hydraulic oil space, thereby pushing the sliding sleeve 258 to move downward, and at the same time the reaction force will be exerted through the action Used on the sliding protrusion 266. Similarly, hydraulic oil is also filled in the sliding protrusion 266 and the sealing block 264. At this time, the sliding protrusion 266 moves inside the sealing block 264 and squeezes the compression spring 262. At the same time, the hydraulic oil will flow to the position of the rotating block 269 through the oil groove 265 and the oil outlet groove 268. Since the extended part of the rotating block 269 slides in the oil outlet groove 268, the hydraulic oil at this time will push the rotating block 269 to move and rotate it on the sealing block 264, thereby causing the rotating block 269 to expand outward. At this time, the push rod 261 is in the process of moving. Since the expanded rotating block 269 cooperates with the locking groove 223 position of the fixed tube 221, the expanded rotating block 269 is blocked by the locking groove 223, thereby blocking the further movement of the linkage device 26 as a whole.

[0038] The extrusion device 24 includes a rotating handle 241, the outer wall of which is fixedly connected to a driving gear 242, a driven gear 243 is arranged outside the rotating handle 241, an extrusion groove 244 is opened in the wall of the driven gear 243, the outer wall of the driving gear 242 is rotatably connected to the outer wall of the protective tube 122, the outer wall of the driving gear 242 is meshed with the outer wall of the driven gear 243, the outer wall of the driven gear 243 is rotatably connected to the outer wall of the fixed tube 221, the outer wall of the driven gear 243 is slidably connected to the outer wall of the inclined sliding rod 225 through the extrusion groove 244, and the extrusion device 24 During the action, the driving gear 242 drives the driven gear 243 to rotate, and the driven gear 243 pushes the inclined slide bar 225 to slide in the magnetic ring 224 through the extrusion groove 244. The upper and lower ends of the inclined slide bar 225 are attracted to the magnetic ring 224. Previously, due to the ejection of the locking block 263, the bottom of the inclined slide bar 225 and the magnetic ring 224 were attracted. The extrusion of the extrusion groove 244 makes the inclined slide bar 225 enter the fixed tube 221. At the same time, the top of the inclined slide bar 225 is attracted to the magnetic ring 224, thereby pressing down the locking block 263 to release the lock of the linkage device 26.

One end of the spring 256 is fixedly connected to the outer wall of the sliding block 257, and the other end of the tension spring 256 is fixedly connected to the outer wall of the wrapping ring 254. The fixed block 251 is fixed on the limit ring 123 and the positioning sleeve 124. The arc block 252 can rotate around the fixed block 251, and the friction plate 253 is fixed on the outer wall of the arc block 252. Both the arc block 252 and the sliding block 257 are magnetic. When the linkage device 26 inside the limit device 22 is activated, the sliding block 257 moves downward under the hydraulic action of the sliding sleeve 258. At this time, the damping rod 255 and the tension spring 256 are fixed at the top and the wrapping ring 254. At this time, the damping rod 255 and the tension spring 256 are both stretched. The moving sliding block 257 will drive the arc block 252 to rotate, so that the friction plate 253 contacts the connecting sleeve 121, generates friction, and realizes the braking of the shaft rod.

[0040] Example 2: Please refer to Figure 1-Figure 11 The present invention provides a technical solution: on the basis of the first embodiment, the shock absorbing device 3 includes a hollow connecting disk 31, the inner wall of the hollow connecting disk 31 is fixedly connected with an elastic frame 32, the inner wall of the elastic frame 32 is plugged with an elastic sheet 33, the inner wall of the hollow connecting disk 31 is fixedly connected with a connecting shaft 36, the outer wall of the connecting shaft 36 is rotatably connected with a diamond-shaped movable frame 35, the end of the diamond-shaped movable frame 35 away from the connecting shaft 36 is rotatably connected with a rolling wheel 34, the outer wall of the hollow connecting disk 31 is fixedly connected with the outer wall of the protective tube 122, the outer wall of the diamond-shaped movable frame 35 is in contact with the outer wall of the diamond-shaped movable frame 35, and the rolling wheel 34 is rollingly connected to the outer wall of the wrapping tube 111 through the rolling groove 113, the hollow connecting plate 31 is fixed on the outer wall of the protective tube 122, the elastic frame 32 and the elastic sheet 33 play a role in buffering vibration, the diamond-shaped movable frame 35 and the rolling wheel 34 rotatably connected on the connecting shaft 36 are rollingly connected to the outer wall of the wrapping tube 111 through the rolling groove 113. When the equipment shaft stalls and causes excessive vibration during operation, the diamond-shaped movable frame 35 will be deformed through the rolling wheel 34 according to the vibration direction, and at the same time, the vibration energy will be converted into kinetic energy and transmitted to the elastic frame 32, and further buffered by the elastic frame 32 and the elastic sheet 33.

[0041] When in use, the self-locking wind power hydraulic equipment realizes effective connection, braking and shock absorption of the rotating shaft of the wind power equipment through the coordinated work of the connecting device 1, the braking device 2 and the shock absorbing device 3, thereby ensuring the stable operation of the equipment under different working conditions.

[0042] The connecting device 1 serves as the connecting part between the equipment and the rotating shaft of the wind power generation equipment, and plays a role of protection and transmission. The wrapping tube 111 is used to connect the rotating shaft of the wind power generation equipment. The brake disc 112 is fixed on the outer wall of the wrapping tube 111. The brake component arranged on the protective tube 122 plays a braking role when the shaft stalls. The rolling groove 113 is arranged on the outer wall of the wrapping tube 111, and cooperates with the rolling wheel 34 of the shock absorbing device 3, which is conducive to the smooth rotation and shock absorption of the equipment during operation. The connecting device 1 provides a stable power input foundation for the entire equipment, ensuring that the rotating shaft of the wind power generation equipment can accurately transmit power to the subsequent device. The outer shell device 12 provides protection and support for the internal device. The connecting sleeve 121 is rotatably connected with the wrapping tube 111, so that the equipment maintains a stable connection relationship during the rotation process. The protective tube 122 enhances the protection of the internal device and prevents external debris from interfering with the operation of the equipment. The limit ring 123 and the positioning sleeve 124 further locate the position of the component to ensure the accurate position of each component during the working process and improve the overall stability of the equipment.

[0043] The brake device 2 is a part that realizes the braking and self-locking functions of the equipment. The positioning block 21 is fixed to the outer wall of the protective tube 122. At the same time, the positioning block 21 is connected to the ground or a fixed component such as a frame to ensure that the position is difficult to deviate during use. When the shaft stalls and needs to be braked, the push ring 23 squeezes the brake disc 112 to achieve preliminary braking. At the same time, the linkage device 26 is driven by squeezing the push ring 23 to enter the interior of the limit device 22 to achieve the braking process. The push rod 261 moves under the drive of the push ring 23. During the movement of the push rod 261, due to the compression spring 26 2 provides elastic force for the locking block 263. When the locking block 263 moves to the pipe position where the magnetic ring 224 is located, the locking block 263 will pop out under the action of the compression spring 262, enter the position where the inclined sliding bar 225 is located and contact the inclined sliding bar 225, and push the top of the inclined sliding bar 225 out of the fixed pipe 221, so that the locking block 263 is engaged in the fixed pipe 221, thereby realizing the self-locking operation of the equipment. When locked, since the braking process needs to maintain pressure for a long time, this self-locking function can effectively prevent the pressure drop caused by pressure leakage;

[0044] Prior to this, the sealing block 264 is pushed toward the direction of the limiting cylinder 222, thereby driving the limiting rod 27 to move. In actual use, in the fixed tube 221, the space surrounded by the limiting cylinder 222, the sliding protrusion 266 and the sliding sleeve 258 is filled with hydraulic oil. Since the position of the limiting cylinder 222 is fixed, when the limiting rod 27 moves, it will squeeze the hydraulic oil space, thereby pushing the sliding sleeve 258 to move downward. At the same time, the reaction force will act on the sliding protrusion 266. Similarly, the sliding protrusion 266 and the sealing block 264 are also filled with hydraulic oil. At this time, the sliding protrusion 266 moves inside the sealing block 264 and squeezes the compression spring 262. At the same time, the hydraulic oil will flow to the position of the rotating block 269 through the oil groove 265 and the oil outlet groove 268. The hydraulic oil at this time will push the rotating block 269 to move and rotate it on the sealing block 264, thereby causing the rotating block 269 to expand outward. At this time, during the movement of the push rod 261, the expanded rotating block 269 cooperates with the locking groove 223 of the fixed tube 221, thereby causing the expanded rotating block 269 to be blocked by the locking groove 223, thereby blocking the further movement of the linkage device 26 as a whole. This design makes the pressure on the sliding sleeve 258 have an upper limit, and it stops when it is pushed to the farthest point during continuous pushing, thereby preventing the hydraulic oil pressure from being too high, causing damage to the components of the friction device 25 and oil leakage. The design of the linkage device 26 makes the braking and self-locking processes of the braking device 2 more reliable, can respond quickly according to actual needs, and improve the safety and stability of the equipment.

[0045] The friction device 25 achieves braking through the contact between the friction plate 253 and the connecting sleeve 121. The fixed block 251 is fixed on the limiting ring 123 and the positioning sleeve 124. The arc block 252 can rotate around the fixed block 251. The friction plate 253 is fixed on the outer wall of the arc block 252. The arc block 252 and the sliding block 257 are both magnetic. When the linkage device 26 inside the limiting device 22 is activated, the sliding block 257 moves downward under the hydraulic action of the sliding sleeve 258. At this time, the damping rod 255 and the tension spring 256 are fixed at the top and the wrapping ring 254. At this time, the damping rod 255 and the tension spring 256 are both stretched. The moving sliding block 257 will drive the arc block 252 to rotate, so that the friction plate 253 contacts the connecting sleeve 121, generating friction force, and realizing the braking of the shaft rod. When the pushing ring 23 stops pushing, the elastic force generated by the stretching spring 256 will drive the sliding block 257 to move upward, and then push back the hydraulic oil, so that the limit rod 27 moves toward the linkage device 26. The structural design of the friction device 25 can adjust the friction force according to the braking demand, and cooperate with the pushing ring 23 to complete the double braking, so that the braking is stable and effective. The setting of the damping rod 255 and the stretching spring 256 makes the braking process more stable and reduces the impact.

[0046] The fixed tube 221 of the limiting device 22 is fixed to the inner wall of the positioning block 21, and the limiting tube 222 limits the limiting rod 27. The magnetic ring 224 and the inclined sliding rod 225 cooperate with each other. When the extrusion device 24 is actuated, the active gear 242 drives the driven gear 243 to rotate, and the driven gear 243 pushes the inclined sliding rod 225 to slide in the magnetic ring 224 through the extrusion groove 244. The upper and lower ends of the inclined sliding rod 225 are attracted to the magnetic ring 224. Previously, due to the ejection of the locking block 263, the bottom of the inclined sliding rod 225 was attracted to the magnetic ring 224, and the extrusion of the extrusion groove 244 made the inclined sliding rod 225 enter the fixed tube 221. At the same time, the top of the inclined sliding rod 225 is attracted to the magnetic ring 224, thereby pressing down the locking block 263 to release the lock of the linkage device 26.

[0047] The shock absorbing device 3 is used to reduce the vibration during the operation of the equipment. The hollow connecting plate 31 is fixed on the outer wall of the protective tube 122. The elastic frame 32 and the elastic sheet 33 play a role in buffering vibration. The diamond-shaped movable frame 35 and the rolling wheel 34 rotatably connected on the connecting shaft 36 are rollingly connected to the outer wall of the wrapping tube 111 through the rolling groove 113. When the equipment shaft stalls and causes excessive vibration during operation, the diamond-shaped movable frame 35 will deform through the rolling wheel 34 according to the direction of vibration, and at the same time convert the vibration energy into kinetic energy and transmit it to the elastic frame 32, which is further buffered by the elastic frame 32 and the elastic sheet 33, thereby effectively reducing the vibration of the equipment, improving the stability of the equipment operation, and extending the service life of the equipment.
