Description

Technical Field

[0001] The present invention belongs to the technical field of wind turbines, and specifically refers to an energy-saving and environment-friendly wind turbine that prevents overloading and damage. Background Art

[0002] With the intensification of the global energy crisis and the increasingly serious environmental pollution problems, the development and utilization of renewable energy have received more and more attention. As a clean and renewable energy, wind power generation has been widely used globally due to its environmental friendliness and cost-effectiveness. However, during the operation of wind turbines, overloading problems caused by excessive wind force may occur, which will not only reduce the power generation efficiency but also may damage the equipment and affect its service life.

[0003] Traditional wind turbines often lack effective protection mechanisms to prevent damage caused by excessive rotation speed when facing strong winds. Some wind turbines use simple speed-limiting devices, but these devices often have slow response speeds and limited adjustment ranges, and cannot adapt to rapidly changing wind speeds, resulting in the inability to effectively protect the power generation equipment under extreme wind speeds. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides an energy-saving and environment-friendly wind turbine that prevents overloading and damage. By setting a primary speed-limiting structure and a compensation speed-limiting structure, the structure is adjusted adaptively according to the rotation speed of the rotating shaft of the wind turbine, so that the resistance received by the rotating shaft during rotation is adjusted correspondingly, thereby ensuring that the rotation speed of the rotating shaft always remains within the appropriate range, avoiding the overload of the wind turbine when the external wind force is large, and effectively solving the problem that the existing wind turbines lack effective protection mechanisms to prevent damage caused by excessive rotation speed proposed by the present invention.

[0005] The technical solution adopted by the present invention is as follows: The present invention provides an energy-saving and environment-friendly wind turbine that prevents overloading and damage, including a fixed support device, a wind power generation component, a primary speed-limiting structure, and a compensation speed-limiting structure. The wind power generation component is arranged at the top of the fixed support device. The primary speed-limiting structure is arranged inside the wind power generation component. The compensation speed-limiting structure is arranged inside the wind power generation component and is arranged on one side of the primary speed-limiting structure. The primary speed-limiting structure includes a sliding bracket, and the compensation speed-limiting structure includes a movable fulcrum. The sliding bracket is connected to the movable fulcrum.

[0006] Furthermore, the primary speed-limiting structure includes a driving gear, a driven gear, a rotating shaft, a rotating block, an adjusting block, an adjusting spring, a first fixed bracket, a sliding extrusion block, a first reset spring, a damping block, a sliding bracket, and a second reset spring. The driving gear is fixedly connected to the wind power generation assembly. The driven gear is meshed with the driving gear. The rotating shaft is fixedly connected to the driven gear. The rotating block is fixedly connected to one end of the rotating shaft away from the driven gear. An activity chute is formed on the outer surface of the rotating block. The adjusting block is slidably connected to the activity chute. One end of the adjusting spring is fixedly connected to the adjusting block, and the other end of the adjusting spring is fixedly connected to the rotating block. The first fixed bracket is fixedly connected to the wind power generation assembly. A first horizontal chute is formed on the inner surface of the first fixed bracket.

One end of the first reset spring is fixedly connected to the sliding extrusion block, and the other end of the first reset spring is fixedly connected to the first fixed bracket. The damping block is fixedly connected to the sliding extrusion block. The sliding bracket is slidably connected to the wind power generation assembly. One end of the second reset spring is fixedly connected to the sliding bracket, and the other end of the second reset spring is fixedly connected to the wind power generation assembly, so that the primary speed-limiting structure can effectively limit the rotation speed of the rotating shaft.

[0007] Furthermore, the compensation speed-limiting structure includes a first adjusting hydraulic cylinder, a telescopic rod, a connecting plate, a lever, a connecting groove, a movable fulcrum, a second fixed bracket, a fixed shaft, a convex block, a transmission rod, and a second adjusting hydraulic cylinder. The first adjusting hydraulic cylinder is fixedly connected to the wind power generation assembly. The telescopic rod penetrates and is slidably connected to the first adjusting hydraulic cylinder. One end of the connecting plate is hinged to the end of the telescopic rod away from the first adjusting hydraulic cylinder. One end of the lever is hinged to the end of the connecting plate away from the telescopic rod. A connecting groove is formed on the lever. The movable fulcrum is slidably connected to the connecting groove. The second fixed bracket is fixedly connected to the wind power generation assembly. The fixed shaft penetrates and is rotatably connected to the second fixed bracket. The convex block is fixedly connected to the fixed shaft. One end of the transmission rod is hinged to one end of the convex block. The second adjusting hydraulic cylinder is hinged to the other end of the transmission rod, so that the compensation speed-limiting structure can help the primary speed-limiting structure to limit the rotation speed of the rotating shaft together.

[0008] Furthermore, the wind power generation assembly includes a fixed frame, a movable closing plate, fastening bolts, a power generation device, a rotating shaft, and blades. The fixed frame is fixedly connected to the fixed support device. The movable closing plate is detachably connected to the fixed frame. The fastening bolts penetrate and are slidably connected to the movable closing plate. The fastening bolts are threadedly connected to the fixed frame. The power generation device is fixedly connected to the inside of the fixed frame. The rotating shaft is fixedly connected to the output end of the power generation device. The rotating shaft penetrates and is rotatably connected to the movable closing plate. The blades are fixedly connected to the end of the rotating shaft away from the power generation device, so that the device can achieve wind power generation.

[0009] Further, the fixed support device includes a mounting base, a fixed column, and a reinforcing plate. The fixed column is fixedly connected to the upper surface of the mounting base. The reinforcing plates are evenly distributed on the outer surface of the fixed column, and the reinforcing plates are fixedly connected to the fixed column.

[0010] Further, the rotating shaft penetrates and is rotatably connected to the fixed frame, and the fixed frame is fixedly connected to the top end of the fixed column.

[0011] Further, the thrust generated by the first adjusting hydraulic cylinder is the same as the thrust generated by the second adjusting hydraulic cylinder, and the initial position of the movable fulcrum is located at the middle position of the lever.

[0012] Further, the sliding bracket is slidably connected within the fixed frame. The adjusting block is arc-shaped, and one end of the sliding bracket away from the power generation device is fixedly connected to the movable fulcrum.

[0013] Further, the diameter dimension of the surface of the damping block is the same as the diameter dimension of the outer surface of the rotating shaft. The surface of the damping block in contact with the rotating shaft has a relatively large surface roughness.

[0014] The beneficial effects achieved by the present invention with the above structure are as follows:

[0015] (1) In order to solve the problem that the existing wind turbines in the present invention lack an effective protection mechanism to prevent damage caused by excessive rotation speed, the present invention sets a primary speed limiting structure and a compensation speed limiting structure, and adaptively adjusts the structure according to the rotation speed of the rotating shaft of the wind turbine, so that the resistance received by the rotating shaft during rotation is adjusted accordingly, thereby ensuring that the rotation speed of the rotating shaft always remains within the appropriate range and avoiding overload of the wind turbine when the external wind force is large;

[0016] (2) Among them, the primary speed limiting structure includes a damping block and an adjusting block. The change in the rotation speed of the rotating shaft can adjust the position of the centrifugal force received by the adjusting block, and the position movement of the adjusting block drives the damping block to fit with the rotating shaft, increasing the resistance received by the rotating shaft during rotation, thereby reducing the rotation speed of the rotating shaft and preventing overload;

[0017] (3) In addition, the compensation speed limiting structure includes a lever and a movable fulcrum. The position of the movable fulcrum can be displaced under the drive of the adjusting block. The change in the position of the movable fulcrum causes corresponding changes in the forces at both ends of the lever, and the convex block included in the compensation speed limiting structure rotates, thereby realizing the control of the damping block, further increasing the resistance received by the rotating shaft, so that the rotation speed of the rotating shaft always remains within the appropriate range, ensuring the safe operation of the wind power generation device, avoiding the situation of overload of the wind turbine, and at the same time preventing the primary speed limiting structure from being unable to effectively reduce the rotation speed of the rotating shaft to the appropriate range.

[0034] Among them, the wind power generation component 2 includes a fixed frame 201, a movable closing plate 202, fastening bolts 203, a power generation device 204, a rotating shaft 205 and blades 206. The fixed frame 201 is fixedly connected to the fixed support device 1. The movable closing plate 202 is detachably connected to the fixed frame 201. The fastening bolts 203 penetrate and slidably connect the movable closing plate 202, and the fastening bolts 203 are threadedly connected to the fixed frame 201. The power generation device 204 is fixedly connected inside the fixed frame 201. The rotating shaft 205 is fixedly connected to the output end of the power generation device 204. The rotating shaft 205 penetrates and rotatably connects the movable closing plate 202. The blades 206 are fixedly connected to one end of the rotating shaft 205 away from the power generation device 204.

[0035] In addition, the fixed support device 1 includes a mounting base 101, fixed columns 102 and reinforcing plates 103. The fixed columns 102 are fixedly connected to the upper surface of the mounting base 101. The reinforcing plates 103 are evenly distributed on the outer surface of the fixed columns 102, and the reinforcing plates 103 are fixedly connected to the fixed columns 102.

[0036] The rotating shaft 303 penetrates and rotatably connects the fixed frame 201. The fixed frame 201 is fixedly connected to the top of the fixed column 102. The thrust generated by the adjusting hydraulic cylinder 1 401 is the same as the thrust generated by the adjusting hydraulic cylinder 2 411. The initial position of the movable fulcrum 406 is located at the middle position of the lever 404.

[0037] The sliding bracket 313 is slidably connected inside the fixed frame 201. The shape of the adjusting block 306 is arc-shaped. One end of the sliding bracket 313 away from the power generation device 204 is fixedly connected to the movable fulcrum 406. The diameter dimension of the surface of the damping block 312 is the same as the diameter dimension of the outer surface of the rotating shaft 205. The surface of the damping block 312 in contact with the rotating shaft 205 has a relatively large surface roughness.

[0038] During specific use, the external wind force acts on the blades 206. The blades 206 drive the rotating shaft 205 to rotate, so that the power generation device 204 generates electricity. While the rotating shaft 205 rotates, the rotating shaft 205 drives the driven gear 302 to rotate through the driving gear 301. The rotation of the driven gear 302 drives the rotating block 304 to rotate through the rotating shaft 303. When the rotation speed of the rotating shaft 205 is normal, the position of the adjusting block 306 remains unchanged, and at this time the power generation device 204 operates normally.

[0039] When the external wind force increases, the rotation speed of the rotating shaft 205 increases. At the same time, the rotation speed of the driven gear 302 also increases. As the speed of the driven gear 302 increases, the centrifugal force received by the adjusting block 306 provided on the rotating block 304 increases. The adjusting block 306 overcomes the supporting force provided by the adjusting spring 307 and begins to displace outward. As the adjusting block 306 displaces outward, the adjusting block 306 drives the sliding bracket 313 and the sliding extrusion block 310 to displace. There are two groups of sliding extrusion blocks 310. The sliding extrusion block 310 displaces along the horizontal sliding groove 309 by overcoming the supporting force provided by the first reset spring 311 under the push of the adjusting block 306. As the sliding extrusion block 310 displaces, the sliding extrusion block 310 drives the damping block 312 to stick to the rotating shaft 205. At this time, the frictional force received by the rotating shaft 205 increases, causing the rotating shaft 205 to decelerate initially.

[0040] The sliding bracket 313 displaces by overcoming the supporting force provided by the second reset spring 314 under the drive of the adjusting block 306. The displacement of the sliding bracket 313 drives the movable fulcrum 406 to displace. After the movable fulcrum 406 starts to displace, the position of the movable fulcrum 406 shifts. At this time, the forces on both ends of the lever 404 are no longer in a balanced state. At this time, the telescopic rod 402 contracts and drives the connecting groove 405 to rotate with the movable fulcrum 406 as the fulcrum through the connecting plate 403. As the lever 404 rotates, the lever 404 drives the convex block 409 to rotate around the fixed shaft 408. The sliding extrusion block 310 in contact with the convex block 409 moves to the outer surface of the rotating shaft 205 under the drive of the rotation of the convex block 409, further increasing the resistance received by the rotating shaft 205 during rotation, so as to ensure that the rotation speed of the rotating shaft 205 will automatically decelerate when it is too fast.

[0041] After the rotation speed of the rotating shaft 205 decelerates to the normal range, the sliding bracket 313 resets to the initial position under the action of the second reset spring 314. The movable fulcrum 406 resets to the initial position under the drive of the sliding bracket 313. During the reset process of the movable fulcrum 406, the adjusting hydraulic cylinder 411 pushes the convex block 409 through the transmission rod 410 to reset by overcoming the supporting force of the adjusting hydraulic cylinder 401. At the same time, the adjusting block 306 retracts to the initial device, and both groups of sliding extrusion blocks 310 reset to the initial position under the action of the first reset spring 311. The above is the overall working process of the present invention. Just repeat this step when using it next time. The actual operation process is very simple and easy.
