[0003] The transmission device in a wind turbine mostly refers to the gearbox inside it. When the existing transmission device in a wind turbine is in use, a sealed bearing is arranged at the connection between the transmission device and the main shaft for support. Due to continuous use and wear, the lubricating grease on the sealed bearing will decrease. The lubrication system in the wind turbine can supplement the lubricating grease for the sealed bearing. However, when the existing transmission device is in use, when the lubrication system fails, the lack of lubricating grease in the sealed bearing cannot be replenished in time, resulting in increased wear inside the sealed bearing and continuous increase in temperature, leading to overheating of the sealed bearing and damage to the sealed bearing.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] The present invention provides a wind power transmission device with feedback regulation function, such as Figures 1 to 9 As shown, it includes a transmission device body 1, the interior of the transmission device body 1 is connected to a main shaft 2, and sealed bearings 3 are provided at both ends of the transmission device body 1. The outer ring of the sealed bearing 3 is fixedly connected to the inner wall of the transmission device body 1, and the inner ring of the sealed bearing 3 is fixedly connected to the outside of the main shaft 2. Openings 4 are equidistantly arranged around the outside of the sealed bearing 3, a filter screen 5 is provided in the opening 4, and a vibration component for driving the filter screen 5 to vibrate is provided inside the sealed bearing 3. A cover plate 6 corresponding to the opening 4 is provided on the outside of the sealed bearing 3, and a rotating shaft 7 is fixedly installed at one end of the cover plate 6 away from the main shaft 2, and connecting plates are rotatably installed at both ends of the rotating shaft 7. 8. The connecting plate 8 is fixed to the outside of the sealed bearing 3. Both ends of the rotating shaft 7 are sleeved with a first torsion spring 9. The two ends of the first torsion spring 9 are fixedly connected to the connecting plate 8 and the rotating shaft 7 respectively. The inner side of the sealed bearing 3 is fixedly installed with an electric push rod 10 corresponding to the filter 5. The telescopic end of the electric push rod 10 is fixedly installed with a bracket 11. The multiple brackets 11 are fixedly connected by a ring plate 12. A push rod 13 is fixedly installed on the side of the bracket 11 close to the cover plate 6. The push rod 13 passes through the sealed bearing 3 and extends to the cover plate 6 to contact it. A temperature sensor 31 that cooperates with the electric push rod 10 is provided on the side of the sealed bearing 3 away from the cover plate 6.

[0030] During use, the temperature value of the temperature sensor 31 can be set. When a fault occurs in the lubrication system of the transmission equipment body 1, the lubricating grease in the sealed bearing 3 is lacking, resulting in increased internal friction and temperature rise. The temperature is transmitted to the temperature sensor 31 through the side wall of the sealed bearing 3. When the temperature reaches the set temperature value, the temperature sensor 31 controls the electric push rod 10 to shorten, causing the bracket 11, the ring plate 12, and the ejector rod 13 to move towards the cover plate 6, making the ejector rod 13 push against the cover plate 6 to rotate, gradually opening the opening 4. When the cover plate 6 rotates, it drives the rotating shaft 7 to rotate, twisting the first torsion spring 9 to generate a force. At the same time, the vibration assembly continuously drives the filter screen 5 to vibrate, shaking off the lubricating grease on the surface of the filter screen 5, making the filter screen 5 unobstructed. Finally, the cover plate 6 opens, and the opening angle between the cover plate 6 and the sealed bearing 3 is 60 degrees. Subsequently, the heat inside the sealed bearing 3 is dissipated outward through the filter screen 5 and the opening 4, reducing the temperature of the sealed bearing 3 and preventing the situation where the internal temperature of the sealed bearing 3 cannot be dissipated, causing damage to the sealed bearing 3 due to excessive internal temperature. The setting of the filter screen 5 can prevent external dust and impurities from entering the sealed bearing 3. When the lubrication system returns to normal and lubricating grease is injected into the sealed bearing 3, its temperature drops below the set temperature value. At this time, the temperature sensor 31 controls the electric push rod 10 to extend and reset, making the ejector rod 13 reset. After the cover plate 6 loses the support of the ejector rod 13, the first torsion spring 9 releases the force, driving the rotating shaft 7 and the cover plate 6 to reset, closing the opening 4 and preventing the subsequent lubricating grease inside the sealed bearing 3 from moving outside the sealed bearing 3.

[0031] As Figures 2 to 7 shown, the vibration assembly includes sliders 14 fixedly connected to both sides of the filter screen 5. The inner wall of the opening 4 is provided with sliding grooves that cooperate with the sliders 14. The sliders 14 are slidably arranged in the sliding grooves. A spring 15 is fixedly installed on the side of the slider 14 away from the cover plate 6. On the side of the filter screen 5 away from the cover plate 6, pull plates 16 are symmetrically and fixedly installed. On the side of the pull plate 16 away from the main shaft 2, there is a toggle plate 17. A round shaft is fixedly installed at the end of the toggle plate 17 close to the pull plate 16. Both ends of the round shaft are rotatably installed with side plates, and the side plates are fixed outside the pull plate 16. A stop block 18 is fixedly installed on the side of the pull plate 16 away from the main shaft 2. The stop block 18 is in contact with the side of the toggle plate 17 away from the cover plate 6. An arc end is provided on the side of the toggle plate 17 close to the pull plate 16. Second torsion springs 19 are sleeved on both ends of the round shaft, and both ends of the second torsion springs 19 are fixedly connected to the round shaft and the side plates respectively. Inside the sealed bearing 3, there is a driving assembly for toggling the toggle plate 17 to move it away from the opening 4.

[0032] The second torsion spring 19 can keep the round shaft and the dialing plate 17 in a vertical state without external force. When the electric push rod 10 shortens, it cooperates with the driving component to dial the dialing plate 17 to rotate away from the opening 4. At this time, due to the existence of the stopper 18, the dialing plate 17 cannot rotate and remains in the vertical state. As the driving component dials the dialing plate 17, the round shaft, the side plate, the pulling plate 16, the filter screen 5, and the slider 14 move away from the cover plate 6. The slider 14 compresses the spring 15 to deform it and generate a force. Subsequently, the driving component cancels the dialing of the dialing plate 17, and the spring 15 releases the force to drive the slider 14 and the filter screen 5 to quickly reset, causing the slider 14 to impact the inner wall of the chute to generate vibration, so that the lubricating grease on the filter screen 5 is shaken off, making the filter screen 5 unblocked. Subsequently, the driving component continuously dials the dialing plate 17 and then cancels the dialing, enabling the filter screen 5 to continuously vibrate, so that the residual lubricating grease on its surface can be shaken off more thoroughly.

[0033] As Figure 3 and Figure 5 shown, the driving component includes multiple pairs of carrier plates 20. The number of pairs of carrier plates 20 corresponds to the number of openings 4. The carrier plates 20 are symmetrically fixed inside the sealed bearing 3. A cylinder 21 is rotatably installed between each pair of carrier plates 20. The outer side of the cylinder 21 is equidistantly and circumferentially fixedly installed with abutting blocks 22 that cooperate with the dialing plate 17. The middle part of the cylinder 21 is circumferentially provided with first teeth 23, and the outer side of the bracket 11 is provided with second teeth 24 that mesh with the first teeth 23.

[0034] When the electric push rod 10 shortens and drives the bracket 11 to move, it cooperates with the second teeth 24 and the first teeth 23 to drive the cylinder 21 to rotate forward, thereby driving the abutting block 22 to move. After the abutting block 22 abuts against the dialing plate 17, at this time, due to the existence of the stopper 18, the dialing plate 17 cannot rotate and remains in the vertical state. The abutting block 22 abuts against the dialing plate 17, causing the round shaft, the side plate, the pulling plate 16, the filter screen 5, and the slider 14 to move away from the cover plate 6. The slider 14 compresses the spring 15 to deform it and generate a force. As the abutting block 22 moves, it separates from the dialing plate 17. At this time, the spring 15 releases the force to drive the slider 14 and the filter screen 5 to quickly reset, causing the slider 14 to impact the inner wall of the chute to generate vibration, so that the lubricating grease on the filter screen 5 is shaken off. Subsequently, the next abutting block 22 abuts against the dialing plate 17 and then separates. Similarly, continuous vibration of the filter screen 5 can be achieved. When the electric push rod 10 extends and resets, the bracket 11 resets and cooperates with the second teeth 24 and the first teeth 23 to drive the cylinder 21 to rotate in reverse, and the abutting block 22 moves accordingly. The abutting block 22 abuts against the dialing plate 17, causing it to abut against the dialing plate 17 to drive the round shaft to rotate, so that the second torsion spring 19 is twisted to deform and generate a force. The dialing plate 17 rotates away from the stopper 18 to make way for the abutting block 22. When the abutting block 22 separates from the dialing plate 17, the second torsion spring 19 releases the force to drive the round shaft and the dialing plate 17 to reset, ensuring that the subsequent abutting block 22 can be reset smoothly.

[0035] like Figure 1 、 Figure 3 、 Figure 6 、 Figure 8 As shown, a cavity 25 is provided inside the cover plate 6, and a plurality of air holes 26 are provided on the side of the cover plate 6 close to the filter 5. A one-way valve 27 is provided in the air hole 26, and an injection component for injecting air into the cavity 25 is provided on the outside of the transmission device body 1.

[0036] When the cover 6 is opened, the temperature sensor 31 controls the injection assembly to inject air into the cavity 25, and then the air pushes the one-way valve 27 to open it. Then the air blows through the air hole 26 to the opening 4, blowing air into the sealed bearing 3, so that the internal hot air is squeezed outward and flows to the outside, thereby accelerating the dissipation of internal heat. The one-way valve 27 can prevent lubricating grease from entering the cavity 25 when no air flow is injected.

[0037] like Figure 1 、 Figure 3 、 Figure 6 、 Figure 8 As shown, the injection assembly includes an annular tube 28, which is fixedly mounted on both ends of the transmission device body 1. The annular tube 28 is connected to the cavity 25 through a hose 29. A fan 30 is fixedly installed on the top of the transmission device body 1, and the output end of the fan 30 is connected to the annular tube 28 through a conduit.

[0038] After the cover plate 6 stops moving, the temperature sensor 31 controls the fan 30 to operate, so that the air is injected into the annular tube 28 through the conduit and then injected into the cavity 25 through the hose 29, thereby injecting air into the cavity 25.

[0039] like Figure 1 and Figure 2 As shown, the top of the sealed bearing 3 and the transmission device body 1 are both provided with corresponding oil filling ports, which are connected to the lubrication system.

[0040] The lubrication system is a lubrication system built into the wind turbine, which is a prior art. Lubricating grease can be injected into the sealed bearing 3 through the lubrication system in conjunction with the oil filling port to lubricate it.

[0041] like Figure 2 As shown, the material of the side wall of the sealed bearing 3 is iron.

[0042] This allows the temperature inside the sealed bearing 3 to be better transferred to the temperature sensor 31 through its side wall.

[0043] like Figure 1 As shown, the transmission device body 1 is specifically a gear box inside a wind turbine.

[0044] Working principle: When in use, the temperature value of the temperature sensor 31 can be set. When the lubrication system of the transmission equipment body 1 fails, the sealed bearing 3 lacks lubricating grease, which increases the internal friction and the temperature. The temperature is transmitted to the temperature sensor 31 through the side wall of the sealed bearing 3. When the temperature reaches the set temperature value, the temperature sensor 31 controls the electric push rod 10 to shorten, so that it moves with the bracket 11, the ring plate 12, and the push rod 13 in the direction close to the cover plate 6, so that the push rod 13 rotates against the cover plate 6, so that the opening 4 is gradually opened. When the cover plate 6 rotates, it rotates with the rotating shaft 7, so that the first torsion spring 9 is twisted to cause its torsional deformation to generate a force. At the same time, the electric push rod 10 shortens and moves with the bracket 11, so that the second gear is matched. 24 and the first tooth 23 drive the cylinder 21 to rotate forward, thereby moving the block 22. After the block 22 contacts the toggle plate 17, the toggle plate 17 cannot rotate due to the presence of the stopper 18 and remains in a vertical state. The block 22 contacts the toggle plate 17, causing the shaft, side plate, pull plate 16, filter screen 5, and slider 14 to move in a direction away from the cover plate 6. The slider 14 compresses the spring 15 to deform and generate a force. As the block 22 moves, it separates from the toggle plate 17. At this time, the spring 15 releases the force and quickly resets the slider 14 and the filter screen 5, causing the slider 14 to hit the inner wall of the chute to generate vibration, which shakes off the lubricating grease on the filter screen 5. Then the next block 22 contacts the toggle plate 17 and then separates again. The same can be achieved. The continuous vibration of the filter 5 causes the lubricating grease on the filter 5 to fall off, making the filter 5 unobstructed. Finally, the cover 6 is opened, and the opening angle between the cover 6 and the sealed bearing 3 is 60 degrees. Then the heat in the sealed bearing 3 is dissipated outward through the filter 5 and the opening 4, so that the temperature of the sealed bearing 3 can be reduced, avoiding the situation where the internal temperature of the sealed bearing 3 cannot be dissipated and the internal temperature is too high to damage the sealed bearing 3. The setting of the filter 5 can prevent external dust and impurities from entering the sealed bearing 3. When the lubrication system returns to normal and the sealed bearing 3 is injected with lubricating grease, its temperature drops below the set temperature value. At this time, the temperature sensor 31 controls the electric push rod 10 to extend and reset, so that the push rod 13 is reset, and the cover 6 loses the push rod. After the support 13, the first torsion spring 9 releases its force and brings the rotating shaft 7 and the cover plate 6 back to their original position, so that the cover plate 6 closes the opening 4, so that the lubricating grease inside the subsequent sealed bearing 3 will not move to the outside of the sealed bearing 3. When the electric push rod 10 is extended and reset, the bracket 11 is reset and cooperates with the second tooth 24 and the first tooth 23 to drive the cylinder 21 to reverse, and the block 22 moves accordingly. The block 22 contacts the toggle plate 17, so that it rotates with the circular shaft against the toggle plate 17, so that the second torsion spring 19 is twisted to deform and generate a force, and the toggle plate 17 rotates away from the stopper 18, so as to make way for the block 22. When the block 22 separates from the toggle plate 17, the second torsion spring 19 releases its force and brings the circular shaft and the toggle plate 17 back to their original position, so as to ensure that the subsequent block 22 can be smoothly reset.After the cover plate 6 is opened, the temperature sensor 31 controls the blower 30 to make it work, so that the air is injected into the annular pipe 28 through the conduit, and then injected into the cavity 25 through the hose 29, realizing the injection of air flow into the cavity 25. Subsequently, the air flow pushes open the one-way valve 27 to make it open. Then, the air flow blows towards the opening 4 through the air holes 26, so as to blow air into the sealed bearing 3, squeezing the internal hot air outwards, making the hot air flow to the outside, thereby accelerating the dissipation of the internal heat faster. The one-way valve 27 can prevent the lubricating grease from entering the cavity 25 when no air flow is injected.;

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
