[0001] The invention belongs to the technical field of wind turbines, and in particular relates to an energy-saving and environment-friendly wind turbine that can prevent overload damage. Background Art

[0002] With the intensification of the global energy crisis and the increasing severity of environmental pollution, the development and utilization of renewable energy have received more and more attention. Wind power generation, as a clean and renewable energy source, has been widely used worldwide due to its environmental friendliness and cost-effectiveness. However, wind turbines may encounter overload problems caused by excessive wind during operation, which will not only reduce the power generation efficiency, but also may cause damage to the equipment and affect its service life.

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

[0034] Among them, the wind power generation component 2 includes a fixed frame 201, a movable closing plate 202, a fastening bolt 203, a power generation device 204, a rotating shaft 205 and a blade 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 bolt 203 penetrates and is slidably connected to the movable closing plate 202, the fastening bolt 203 is threadedly connected to the fixed frame 201, the power generation device 204 is fixedly connected to the inside of 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 is rotatably connected to the movable closing plate 202, and the blade 206 is fixedly connected to the 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, a fixed column 102 and a reinforcing plate 103, the fixed column 102 is fixedly connected to the upper surface of the mounting base 101, the reinforcing plate 103 is evenly distributed on the outer surface of the fixed column 102, and the reinforcing plate 103 is fixedly connected to the fixed column 102.

[0036] The rotating shaft 303 penetrates and is rotatably connected to the fixed frame 201 , and 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 in the middle position of the lever 404 .

[0037] The sliding bracket 313 is slidably connected in the fixed frame 201, the adjustment block 306 is in the shape of an arc, the end of the sliding bracket 313 away from the power generation equipment 204 is fixedly connected to the movable fulcrum 406, the diameter of the surface of the damping block 312 is the same as the diameter of the outer surface of the rotating shaft 205, and 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, and the blades 206 drive the rotating shaft 205 to rotate, so that the power generation equipment 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, and the driven gear 302 rotates through the rotating shaft 303 to drive the rotating block 304 to rotate. When the rotation speed of the rotating shaft 205 is normal, the position of the adjusting block 306 remains unchanged, and the wind turbine 204 operates normally at this time.

[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 on the adjusting block 306 set on the rotating block 304 increases, and the adjusting block 306 overcomes the supporting force provided by the adjusting spring 307 and begins to move outward. As the adjusting block 306 moves outward, the adjusting block 306 will drive the sliding bracket 313 and the sliding extrusion block 310 to move. The sliding extrusion block 310 is provided with two groups. The sliding extrusion block 310 overcomes the supporting force provided by the return spring 311 and moves along the horizontal slide groove 309 under the push of the adjusting block 306. As the sliding extrusion block 310 moves, the sliding extrusion block 310 drives the damping block 312 to stick to the rotating shaft 205. At this time, the friction force on the rotating shaft 205 increases, causing the rotating shaft 205 to initially slow down.

[0040] The sliding bracket 313 is displaced under the drive of the adjustment block 306 to overcome the supporting force provided by the return spring 2 314. The displacement of the sliding bracket 313 drives the movable fulcrum 406 to displace. After the movable fulcrum 406 starts to move, the position of the movable fulcrum 406 shifts. At this time, the forces at both ends of the lever 404 are no longer balanced. At this time, the telescopic rod 402 contracts and drives the connecting groove 405 to rotate around the movable fulcrum 406 through the connecting plate 403. As the lever 404 rotates, the lever 404 drives the protrusion 409 to rotate around the fixed shaft 408. The sliding extrusion block 310 abutting against the protrusion 409 moves to the outer surface of the rotating shaft 205 under the drive of the rotation of the protrusion 409, so that the resistance to the rotation of the rotating shaft 205 is further increased, thereby ensuring that the rotation speed of the rotating shaft 205 will automatically slow down when it is too fast.

[0041] After the rotation speed of the rotating shaft 205 is decelerated to a normal range, the sliding bracket 313 is reset to the initial position under the action of the reset spring 2 314, and the movable fulcrum 406 is reset to the initial position driven by the sliding bracket 313. During the resetting process of the movable fulcrum 406, the adjusting hydraulic cylinder 2 411 pushes the protrusion 409 through the transmission rod 410 to overcome the supporting force of the adjusting hydraulic cylinder 1 401 and reset. At the same time, the adjusting block 306 shrinks back to the initial device, and the two sets of sliding extrusion blocks 310 are reset to the initial position under the action of the reset spring 1 311. The above is the overall working process of the present invention. You can repeat this step when you use it next time. The actual operation process is very simple and easy.

[0042] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
