When the wind power generation device is used, the fan blades 1 are blown by outdoor wind power to drive the fan blades 1 to rotate, the fan blades 1 drive the large rotating rods 6 to rotate, the large rotating rods 6 change the speed through the speed change gear box 7, so that the slow rotation of the large rotating rods 6 is transmitted to the high-speed rotation of the small rotating rods 8 and is connected to the generator 9, the generator 9 generates electricity, meanwhile, typhoon is scraped outdoors, when the wind power is too strong, the rotating speed transmitted to the small rotating rods 8 is too high to exceed the working load of the generator 9, at the moment, the fixed disk 301 on the outer wall of the small rotating rods 8 is synchronously driven by the small rotating rods 8 to rotate at a high speed, meanwhile, the sliding blocks 305 inside the fixed disk 301 are thrown out by the centrifugal force of the high-speed rotation, so that the sliding blocks 305 slide on the inner wall of the fixed disk 301 and extend to the inside of the hollow circular ring 302, and at the moment, the magnet pressing blocks 309 inside the fixed disk 301 are in contact with the inner wall of the hollow circular ring 302, therefore, the magnet pressing block 309 begins to incline on the inclined surface inside the hollow circular ring 302, the magnet pressing block

block 309 cannot be damaged, but the magnet pressing block 309 can be prevented from being driven to rotate by the sliding block 305 and the fixed disc 301 to the small rotating rod 8, so that the problem that the rotating speed of the small rotating rod 8 is not too high, the generator 9 is subjected to overload work, internal parts are damaged at high temperature, the service life of the generator 9 is prolonged, the condition that power supply is insufficient due to faults is avoided, through automatic speed limitation, the time and energy consumed by workers for continuously checking are reduced, the work load is reduced, the work efficiency is improved, and when the rotating speed of the small rotating rod 8 is too high and the generator 9 starts to work at high intensity and generate heat, the sliding block 305 drives the magnet pressing block 309 to be separated from the inside of the fixed disc 301, so that the magnet pressing block 309 is separated from the magnetic attraction of the magnet sliding plate 401, therefore, the magnet sliding plate 401 is quickly rebounded by the rebounding force of the elastic plate 403 to push the hinge rod 404 to the small sliding block 405 to slide on the inner wall of the fixed disk 301, and pushes the small fan blade 406 to extend out of the fixed disk 301, so that when the small rotating rod 8 drives the fixed disk 301 to rotate at a high speed, the small fan blade 406 can extend out of the fixed disk 301, so as to perform fanning to blow air on the generator 9, and perform air blowing circulation through the air inlet and the air outlet formed in the outer wall of the box body 2 to dissipate heat of the generator 9, and further, when the generator 9 is kept to work with high strength and high efficiency, the generator 9 is automatically blown to dissipate heat, internal damage of the generator 9 caused by high temperature is avoided, and simultaneously, when the generator 9 is dissipated heat by extending out of the small fan blade 406 during high-load work of the generator 9, the rotating speed of the fixed disk 301 is greatly reduced by the wind resistance caused by the small fan blade 406, therefore, the rotating speed of the small rotating rod 8 can be further limited, the small rotating rod 8 can rotate smoothly and stably under medium and small wind to provide power for the generator 9 to generate power, when the small rotating rod 8 meets strong wind, the wind resistance generated by the small fan blades 406 can automatically limit the rotating speed of the small rotating rod 8, the maximization of wind power resource utilization is further ensured while no overload is ensured, meanwhile, when the magnet pressing block 309 is pushed into the hollow circular ring 302 to be in contact with the projection 303 to be shifted, the magnet pressing block 309 pushes the sliding plate 307 to the elastic ball 306 to rebound and deform through the connecting rod 308, so that the magnet pressing block 309 can vibrate and slide left and right back and forth, the extrusion block 501 in the magnet pressing block 309 can continuously slide left and right in the magnet pressing block 309 through the inertia of left and right back and forth vibration and forth in the left and right direction through the air injection groove 503, and the small sliding plate 504 is pushed to continuously move back and forth in the up and down direction on the outer wall of the hollow circular ring 302 through the air injection groove 503 Sliding friction, the air of extrusion piece 501 opposite side then inhales through the thin air channel of magnet briquetting 309 inner wall and discharges, guarantee that extrusion piece 501 can normally carry out the horizontal slip work, thereby make can further slide from top to bottom through little slide 504 when magnet briquetting 309 stirs with lug 303, make little slide 504 of hugging closely with hollow ring 302 inner wall can carry out the promotion of further frictional force to hollow ring 302 inner wall, avoided because long-time the back of using, the condition that frictional force descends after the wearing and tearing that leads to of the same position friction that leads to appears, then promote the braking to 8 rotational speeds of little bull stick and guarantee the stability and the permanence of braking through the friction in different positions.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical scope of the present invention and the equivalent alternatives or modifications according to the technical solution and the inventive concept of the present invention within the technical scope of the present invention.
