Description

Technical Field

[0001] The present invention relates to the technical field of wind power protection devices, and particularly to a wind power generation device with a safety protection function. Background Art

[0002] Wind power generation has significant advantages in terms of environmental protection. No harmful substances are generated during the power generation process, and wind energy, as a renewable resource, is inexhaustible. Therefore, wind turbines are becoming more and more widely distributed in our country. Therefore, it is very important to take certain protective measures for these generators to ensure their long-term normal operation.

[0003] Referring to the patent of CN202010456665.9, which relates to a wind power generation group with protective performance for wind power generation, including a main pole, a wind direction and wind speed measuring instrument, and a hydraulic rod. A secondary pole is arranged at the top of the main pole, and a base body is arranged at the bottom end of the main pole. The base body is connected to the main pole by bolts, and the main pole and the secondary pole are fixedly connected. A fixing ring is arranged at the lower end of the outer wall of the secondary pole, and a connecting piece is connected to the outside of the fixing ring. A reserved groove is opened on the inner side of the outer wall of the connecting piece. The beneficial effects of the present invention are: through the setting of the hydraulic rod, the connecting shaft, the connecting piece, the elastic piece and the fixing ring, and the hydraulic rod and the connecting piece form a movable structure through the connecting shaft. When the humidity at the connection of the main pole and the secondary pole formed by welding is relatively high, the hydraulic rod can be started, and under the action of the connecting shaft, the connecting piece is driven to perform a closing operation, reducing the contact area between the connection of the main pole and the secondary pole and the outside air, and extending the service life of the device.

[0004] Based on the retrieval of the above patent and combined with the current usage situation of wind turbines, it is found that wind turbines still have the following disadvantages:

[0005] Wind turbines are also threatened by lightning. Although some lightning protection measures have been taken, such as installing lightning rods and lightning arresters above the motor nacelle to prevent lightning from penetrating the nacelle and damaging the equipment, the current lightning rods have poor stability and will shake violently in strong wind weather, which will affect the normal operation of the lightning rods.

[0006] In response to the violent shaking of the entire wind turbine in strong wind weather, it is necessary to strengthen the overall safety protection measures of the wind turbine. Summary of the Invention

[0019] The electromagnetic generator is fixed inside the outer shell of the motor cabin. The front end of the electromagnetic generator is connected to the first coupling in a driving manner.

The sensor monitors the rotational speed data of the second coupling and sends the rotational speed data to the controller;

[0020] The motor cabin component further includes a clamp driving mechanism and a pair of clamping plates. The clamp driving mechanism drives the clamping plates to clamp or loosen the second coupling;

[0021] The controller is fixed inside the outer shell of the motor cabin. The controller adjusts the rotational speed of the second coupling by controlling the clamp driving mechanism.

[0024] The driving motor is fixed on the fixing frame. The driving motor is in driving connection with the bidirectional lead screw. The bidirectional lead screw is rotatably connected to the fixing frame;

[0025] The sliding plate is in threaded connection with the bidirectional lead screw and is slidably connected to the transverse chute. An arc-shaped clamping plate is installed on the upper end surface of each sliding plate.

[0026] Furthermore, a fixing sleeve is provided on the outside of the second coupling. Resistance strips are circumferentially and evenly distributed on the outside of the fixing sleeve.

[0036] The lifting sleeve is sleeved outside the fixed rod, and the left and right ends of the sliding rod are respectively slidably connected to the corresponding second connecting rod and the first connecting rod, so that the distance between the adjustable sliding sleeve and the lifting sleeve can be adjusted. The sliding sleeve will move up and down under the blowing of the wind, which can reduce the shaking amplitude of the lightning rod and prevent damage caused by excessive shaking amplitude of the lightning rod. When the sliding sleeve moves up and down, the distance between the sliding sleeve and the lifting sleeve will also change accordingly, ensuring the smooth movement of the sliding sleeve. In this way, for strong wind weather, the stability of the lightning rod can be improved. Avoid severe shaking of the lightning rod in strong wind weather and ensure the normal operation of the lightning rod. BRIEF DESCRIPTION OF THE DRAWINGS

The fixing block 6 is fixedly installed on the upper end face of the base 1, and a lightning rod 601 is fixedly installed on the upper end face of the fixing block 6.

[0058] The fixing ring 7 includes a ring sleeved outside the lightning rod 601 at intervals, and the ring is fixedly connected to the lightning rod 601.

An inclined fixing rod 7012 is fixed to the lower end face of the sleeve 701, and the lower ends of all the fixing rods 7012 are fixed to the upper end face of the fixing block 6. The base 1 and the fixing block 6 fix the bottom end of the lightning rod 601, and the fixing ring 7 is used to stabilize the position of the bottom end of the lightning rod 601 at a position slightly above the bottom end near the bottom end.

[0059] Preferably, the fixing ring 7 is located outside above the fixing block 6, and all the fixing rods 7012 expand from bottom to top. The lower ends of all the fixing rods 7012 extend inwards and downwards to be fixed to the upper end face of the fixing block 6. The fixing ring 7 restricts the movement range of the lightning rod 601 near the bottom end position.

[0060] Preferably, a reinforcing rod 7011 is installed on the inner end face of the fixing ring 7, and the other end of the reinforcing rod 7011 is fixedly connected to the lightning rod 601, which can improve the stability of the fixing ring 7.

[0061] The sliding sleeve 8 is slidably sleeved outside the lightning rod 601, and a plurality of first connecting rods 801 are circumferentially and evenly distributed on the sliding sleeve 8; the lifting sleeve 9 is slidably sleeved outside each fixing rod 7012, and a second connecting rod 901 is fixedly installed on the inner end surface of the lifting sleeve 9. A sliding rod 10 is connected between each second connecting rod 901 and each first connecting rod 801, and the two ends of the sliding rod 10 are respectively slidably connected to the corresponding second connecting rod 901 and first connecting rod 801. The first connecting rod 801, the sliding rod 10, and the second connecting rod 901 are horizontally arranged and arranged along the radial direction of the fixed ring 7.

[0062] Preferably, the middle of the sliding rod 10 is a round rod, and sliding blocks 1001 with a diameter larger than that of the round rod are arranged at both ends of the round rod. The second connecting rod 901 is provided with a second sliding hole 9011 that can be slidably matched with the sliding block 1001, and the first connecting rod 801 is provided with a first sliding hole that can be slidably matched with the sliding block 1001. The two sliding blocks 1001 respectively extend into the corresponding second sliding hole 9011 and first sliding hole. The inner walls of the adjacent ends of the second connecting rod 901 and the first connecting rod 801 are necked down to prevent the sliding blocks 1001 from separating from the second connecting rod 901 and the first connecting rod 801 respectively. The sliding block 1001 at the left end of the sliding rod 10 slides inside the first sliding hole, and the sliding block 1001 at the right end of the sliding rod 10 slides inside the second sliding hole 9011.

The round rod in the middle of the sliding rod 10 can pass through the two necked-down holes. That is, the first sliding hole and the second sliding hole 9011 are stepped holes.

[0063] Embodiment 2: In strong wind weather, the rotation speed of the wind turbine 1101 will become faster and faster. When the rotation speed exceeds the mechanical strength of the blades and the entire equipment, it is easy to cause the phenomenon of blade fracture, resulting in equipment failure and inability to generate electricity normally. Therefore, the structure of the nacelle component 11 is optimized to improve the safety protection function. See Figure 11-14 .

[0064] Specifically, a support column 1102 is fixed to the lower end surface of the nacelle housing.

[0065] The nacelle component 11 further includes a speed increaser 12, a first coupling 1201, an electromagnetic generator 13, a second coupling 14, and a controller 16 that are sequentially arranged inside the nacelle housing. The speed increaser 12 is fixed at the front position inside the nacelle component 11. The input shaft at the front end of the speed increaser 12 is fixedly connected to the wind turbine 1101, and a first coupling 1201 is arranged at the rear end of the speed increaser 12.

[0066] The electromagnetic generator 13 is fixed inside the motor cabin component 11. The front end of the electromagnetic generator 13 is in driving connection with the first coupling shaft 1201, and a second coupling shaft 14 is provided at the rear end of the electromagnetic generator 13. A sensor is provided on the second coupling shaft 14, and the sensor monitors the rotational speed data of the second coupling shaft 14 and sends the rotational speed data to the controller 16.

[0067] The motor cabin component 11 further includes a clamp driving mechanism and a pair of clamping plates 1901. The clamp driving mechanism drives the clamping plates 1901 to clamp or loosen the second coupling shaft 14.

[0068] The controller 16 is fixed inside the motor cabin component 11, and the controller 16 adjusts the rotational speed of the second coupling shaft 14 by controlling the clamp driving mechanism.

[0069] Preferably, the clamp driving mechanism includes a fixing frame 17, a driving motor 18, a bidirectional lead screw 1801, and a pair of sliding plates 19.

[0070] The main body of the fixing frame 17 is of a U-shaped structure, including a bottom plate and two vertical plates. The fixing frame 17 is fixed inside the motor cabin housing. The fixing frame 17 is located between the electromagnetic generator 13 and the controller 16, and a transverse sliding groove 1701 is provided on the surface of the bottom plate of the fixing frame 17.

[0071] The driving motor 18 is fixed on the fixing frame 17, and the driving motor 18 is in driving connection with the bidirectional lead screw 1801. The bidirectional lead screw 1801 is rotationally connected to the fixing frame 17. The sliding plate 19 is threadedly connected to the bidirectional lead screw 1801 and is slidably connected to the transverse sliding groove 1701. An arc-shaped clamping plate 1901 is installed on the upper end surface of each sliding plate 19.

[0072] The controller 16 is fixedly installed at the rear position inside the motor cabin housing. The end of the second coupling shaft 14 is rotationally connected inside the housing of the controller 16. Monitoring the rotational speed of the second coupling shaft 14 by using a sensor is prior art and will not be elaborated here.

[0073] The driving motor 18 is fixedly installed on the outer end surface of a vertical plate of the fixing frame 17. The driving motor 18 is in driving connection with a bidirectional lead screw 1801. The two ends of the length of the bidirectional lead screw 1801 are rotationally connected to the two vertical plates of the fixing frame 17. There are two groups of symmetrically arranged sliding plates 19, and the sliding plates 19 are threadedly connected to the bidirectional lead screw 1801. The driving motor 18 drives the bidirectional lead screw 1801 to rotate, so as to realize the mutual approach or separation of the two sliding plates 19. The direction of the bidirectional lead screw 1801 is perpendicular to the direction of the second coupling shaft 14.

[0074] The end of the second coupling shaft 14 extends into the interior of the housing of the controller 16. The controller 16 can monitor the rotational speed of the second coupling shaft 14. When the controller 16 monitors that the rotational speed of the second coupling shaft 14 is too fast, the driving motor 18 drives the bidirectional lead screw 1801 to rotate. Through the setting that the bidirectional lead screw 1801 is threadedly connected to the two sliding plates 19, the two sliding plates 19 will move inward simultaneously. At this time, the clamping plates 1901 at the upper ends of the two sliding plates 19 will fit against the outer surface of the second coupling shaft 14, thereby reducing the rotational speed of the second coupling shaft 14 and playing a role in braking and reducing the speed of the wind wheel 1101.

[0075] Preferably, a fixing sleeve 15 is arranged outside the second coupling shaft 14, and resistance strips 1501 are circumferentially and evenly distributed on the outer circumference of the fixing sleeve 15. At this time, the clamping plates 1901 at the upper ends of the two sliding plates 19 will tightly hold the fixing sleeve 15 outside the second coupling shaft 14. Resistance strips 1501 are evenly installed on the outer circumference of the fixing sleeve 15, which increases the friction between the fixing sleeve 15 and the clamping plates 1901 and improves the braking effect. The limit blocks 1902 at the lower ends of the sliding plates 19 are slidably fitted in the transverse sliding grooves 1701 on the surface of the fixing frame 17, so that the sliding plates 19 will not deflect during movement.

[0076] Among them, a fixing sleeve 15 is installed outside the second coupling shaft 14, resistance strips 1501 are evenly installed on the outer circumference of the fixing sleeve 15, the controller 16 is electrically connected to the driving motor 18, a limit block 1902 is installed on the lower end surface of the sliding plate 19, and the limit block 1902 slides and is slidably fitted in the transverse sliding groove 1701 on the surface of the bottom plate of the fixing frame 17. Two arc-shaped clamping plates 1901 are installed on the upper end surface of the sliding plate 19.

[0077] By adopting the above solution, the technical effects are as follows: When the wind turbine 1101 rotates, due to its relatively slow rotation speed, through the setting of the speed increaser 12, the rotation speed of the first coupling shaft 1201 and the second coupling shaft 14 can be increased. After the rotation speed of the first coupling shaft 1201 is increased, the power generation efficiency of the electromagnetic generator 13 can be improved. The controller 16 can monitor the rotation speed of the second coupling shaft 14. In case of strong wind weather, the rotation speed of the wind turbine 1101 increases greatly. When the rotation speed of the wind turbine 1101 exceeds the warning value, it will cause the blades to break. At this time, when the controller 16 monitors that the rotation speed of the second coupling shaft 14 is too fast, it can transmit a signal to the driving motor 18. After receiving the signal, the driving motor 18 will drive the bidirectional lead screw 1801 to rotate. Through the setting that the bidirectional lead screw 1801 is threadedly connected to the two sliding plates 19, the two sliding plates 19 will move inward simultaneously. At this time, the clamping plates 1901 at the upper ends of the two sliding plates 19 will closely fit with the fixed sleeve 15 outside the second coupling shaft 14, thereby reducing the rotation speed of the second coupling shaft 14 and playing a role in braking the speed reduction of the wind turbine 1101. Resistance strips 1501 are evenly installed on the outer circumference of the fixed sleeve 15, which increases the friction force between the fixed sleeve 15 and the clamping plate 1901 and improves the braking effect. The limit blocks 1902 at the lower ends of the sliding plates 19 are slidably fitted in the horizontal sliding grooves 1701 on the surface of the fixed frame 17.

[0085] The limiting blocks 501 can be commonly inserted into one of the first card slot 3011 and the second card slot 401. The upper end of the cover plate 5 serves to protect the fixing screw 4, and the limiting blocks 501 serve to prevent the fixing screw 4 from rotating.

[0086] Preferably, the bottom ends of the two sides of the limiting block 501 facing the first card slot 3011 and the second card slot 401 are inclined planes, so that the bottom end of the limiting block 501 becomes thinner, which facilitates the insertion of the limiting block 501 into the first card slot 3011 and the second card slot 401, and the limiting block 501 is clamped inside the first card slot 3011 and the second card slot 401.

[0092] A fixing screw 4, the fixing screw 4 is clamped in the connecting hole 301 on the surface of the connecting plate 3. The fixing screw 4 is threadedly connected to the motor nacelle housing.

[0093] A cover plate 5, the main body of the cover plate 5 is located on the upper end surface of the fixing screw 4. A fixing box 502 is installed on the upper end surface of the main body, and a limiting block 501 is installed on the lower end surface of the cover plate 5. The fixing box 502 has a dust cap, and lubricating oil can be introduced into the fixing box 502 after the dust cap is opened.

[0094] A fixing block 6, the fixing block 6 is fixedly installed at the middle position of the upper end surface of the base 1, and a lightning rod 601 is fixedly installed on the upper end surface of the fixing block 6.

[0095] The fixed ring 7 is located outside the lightning rod 601. Four sleeves 701 are annularly installed on the outer circumference of the fixed ring 7. An inclined fixed rod 7012 is installed on the lower end surface of the sleeve 701, and the lower end of the fixed rod 7012 is installed on the upper end surface of the fixed block 6.

[0096] The sliding sleeve 8 is sleeved outside the lightning rod 601. Four first connecting rods 801 are annularly installed on the outer circumference of the sliding sleeve 8.

[0097] The lifting sleeve 9 is sleeved outside the fixed rod 7012. A second connecting rod 901 is fixedly installed on the inner end surface of the lifting sleeve 9.

[0098] The sliding rod 10 is provided with a sliding block 1001 at each of its left and right ends. The sliding block 1001 is of a circular plate structure.

[0099] Among them, the connection hole 301 is preferably of a convex structure, that is, thinner at the top and thicker at the bottom. A plurality of first card slots 3011 are evenly opened on the surface of the upper part of the connection hole 301. A second card slot 401 is opened on the surface of the fixed screw 4. The widths of the first card slot 3011 and the second card slot 401 are the same. The lower end surface of the limiting block 501 is of an inclined structure on both left and right sides. The limiting block 501 is clamped inside the first card slot 3011 and the second card slot 401.

[0100] By adopting the above scheme, the technical effects brought are as follows: A second card slot 401 is opened on the outside of the fixed screw 4, and a first card slot 3011 is opened on the inner surface of the upper part of the connection hole 301. When the worker clamps the fixed screw 4 inside the connection hole 301, the first card slot 3011 and the second card slot 401 can be aligned. Then, the limiting block 501 at the lower end of the cover plate 5 is clamped in the first card slot 3011 and the second card slot 401, which can prevent the fixed screw 4 from rotating in the connection hole 301, improve the stability of the fixed screw 4. The main body of the cover plate 5 is located on the fixed screw 4, which can prevent some external impurities from entering the gap between the fixed screw 4 and the connection hole 301, playing a role in protecting the fixed screw 4.

[0101] Among them, a drainage groove 5011 is formed inside the limit block 501. The upper end of the drainage groove 5011 communicates with the fixed box 502. The bottom plate surface of the fixed box 502 is of a funnel-shaped structure. During use, the fixed box 502 is installed at the top end of the cover plate 5, and the drainage groove 5011 is formed inside the limit block 501. When disassembling the fixing screw 4, lubricating oil can be poured into the fixed box 502, and then the lubricating oil will enter between the fixing screw 4 and the connection hole 301 through the drainage groove 5011, playing a lubricating role, enabling the worker to more easily remove the fixing screw 4. In actual operation, the worker can set a plug plate or a dust cap at the upper end of the fixed box 502 to prevent foreign objects or rainwater from entering the fixed box 502.

[0102] A first sliding hole is formed inside the first connecting rod 801, and a second sliding hole 9011 is formed inside the second connecting rod 901. The sliding block 1001 at the left end of the sliding rod 10 is slidably clamped inside the first sliding hole, and the sliding block 1001 at the right end of the sliding rod 10 is slidably clamped inside the second sliding hole 9011.

[0103] By adopting the above solution, the technical effects brought are as follows: Since the installation positions of wind turbines are mostly in places with strong wind such as mountaintops, the lightning rod 601 will shake violently under the blowing of the wind, which is likely to reduce the stability of the base 1. The sliding sleeve 8 is sleeved outside the lightning rod 601, the lifting sleeve 9 is movably sleeved outside the fixed rod 7012, and the sliding blocks 1001 at the left and right ends of the sliding rod 10 are respectively slidably clamped in the first sliding hole and the second sliding hole 9011, so that the sliding sleeve 8 will move up and down under the blowing of the wind. When the sliding sleeve 8 moves up and down, the shaking amplitude of the lightning rod 601 can be reduced, preventing the lightning rod 601 from being damaged due to excessive shaking amplitude, and reducing the influence on the base 1. When the sliding sleeve 8 moves up and down, the distance between the first connecting rod 801 and the second connecting rod 901 will also change accordingly, ensuring the smooth movement of the sliding sleeve 8.

[0104] The two side surfaces of the motor nacelle housing are of an arc structure, so that rainwater will not accumulate on the surface of the motor nacelle housing. A first through hole 101 is formed on the surface of the base 1. The worker can pass a bolt through the first through hole 101 to fix the base 1 above the motor nacelle component 11. A rocker plate 2 is rotatably connected in the device groove 102 at the lower end of the base 1. A connecting plate 3 is fixedly installed at the end of the rocker plate 2. The connecting plate 3 is connected to the motor nacelle component 11 through a fixing screw 4, which can improve the stability of the base 1 on the upper end of the motor nacelle housing.

[0105] The connecting plate 3 is connected to the outer shell of the motor compartment through the fixing screw 4. When the lightning rod 601 is shaken by the wind, it is easy to cause the fixing screw 4 to become loose. By providing a second card slot 401 on the outside of the fixing screw 4 and a first card slot 3011 on the inner surface of the upper part of the connection hole 301, when the worker snaps the fixing screw 4 into the connection hole 301, the first card slot 3011 can be aligned with the second card slot 401. Then, the limiting block 501 at the lower end of the cover plate 5 is snapped into the first card slot 3011 and the second card slot 401, which can prevent the fixing screw 4 from rotating in the connection hole 301. The main body of the cover plate 5 is a circular plate and can be located outside the fixing screw 4, which can prevent some external impurities from entering the gap between the fixing screw 4 and the connection hole 301, playing a role in protecting the fixing screw 4. A fixing box 502 is installed on the top surface of the main body of the cover plate 5. A drainage groove 5011 is provided inside the limiting block 501. When disassembling the fixing screw 4, lubricating oil can be poured into the fixing box 502, and then the lubricating oil will enter between the fixing screw 4 and the connection hole 301 through the drainage groove 5011, playing a lubricating role, making it easier for the worker to remove the fixing screw 4. Since most of the installation positions of wind turbines are in places with strong winds such as mountaintops, the lightning rod 601 will shake violently under the blowing of the wind, which is likely to reduce the stability of the lightning rod 601. The sliding sleeve 8 is sleeved outside the lightning rod 601, the lifting sleeve 9 is sleeved outside the fixing rod 7012, and the sliding blocks 1001 at the left and right ends of the sliding rod 10 are respectively slidably clamped in the first sliding hole and the second sliding hole 9011. When the sliding sleeve 8 moves up and down under the blowing of the wind, the shaking amplitude of the lightning rod 601 can be reduced, avoiding damage to the lightning rod 601 due to excessive shaking amplitude. When the sliding sleeve 8 moves up and down, the distance between the first connecting rod 801 and the second connecting rod 901 will also change accordingly, ensuring the smooth movement of the sliding sleeve 8. The surface of the base 1 is evenly provided with first through holes 101. The base 1 can be fixed to the upper surface of the outer shell of the motor compartment by passing screws through the first through holes 101. The rocker plate 2 is rotatably connected to the device slot 102 on the lower surface of the base 1, and a connecting plate 3 is fixedly installed on the outer end surface of the rocker plate 2. The worker can also pass the fixing screw 4 through the connection hole 301 and install the connecting plate 3 on the top surface of the outer shell of the motor compartment, so as to double-fix the lightning rod 601, thereby improving the stability.
