本发明提供了一种风力发电机的限速冷却装置。具备以下有益效果:The present invention provides a speed-limiting cooling device for a wind turbine generator, which has the following beneficial effects:

(1)、一种风力发电机的限速冷却装置,通过设置缓速降温冷却机构,从而使得螺纹推块旋转推出至转块处位置时,被转块阻挡停止,同时此时的螺纹推块转动四十五度,小扇叶处于四十五度的旋转角度,从而通过小扇叶四十五度角度继而吹动更多的风力对发电机进行散热降温,并且可以在低转速时通过小扇叶较小的倾斜角度,保证对发电机进行小幅的吹风散热降温,继而针对小转杆不同转速与发电机不同的工作负荷下自动调整转速对发电机进行降温冷却工作。(1) A speed-limited cooling device for a wind turbine generator, which is provided with a slow-speed cooling mechanism so that when the threaded push block is rotated and pushed out to the position of the rotating block, it is blocked and stopped by the rotating block. At the same time, the threaded push block is rotated by 45 degrees, and the small fan blade is at a rotation angle of 45 degrees, so that more wind can be blown by the 45-degree angle of the small fan blade to dissipate heat and cool the generator. At a low speed, the small fan blade can be tilted at a smaller angle to ensure a small amount of wind blowing to dissipate heat and cool the generator, and then the speed is automatically adjusted according to different speeds of the small rotating rod and different working loads of the generator to cool the generator.

(2)、一种风力发电机的限速冷却装置,通过设置缓速降温冷却机构,在小扇叶被推出后处于四十五度角度的时候,在对发电机进行吹风散热的同时,小扇叶也会受到较大的风阻,从而通过圆盘带动小转杆进行制动,对小转杆与扇叶进行一定的减速作用,对小转杆进行了限速,同时也对发电机的工作负荷进行了稳定,保证了发电机的工作稳定性,避免过热损毁的情况出现。(2) A speed limiting cooling device for a wind turbine generator is provided with a slow cooling mechanism. When the small fan blades are pushed out and are at an angle of 45 degrees, while the generator is cooled by blowing air, the small fan blades will also be subject to greater wind resistance, thereby driving the small rotating rod to brake through the disc, decelerating the small rotating rod and the fan blades to a certain extent, limiting the speed of the small rotating rod, and stabilizing the working load of the generator, thereby ensuring the working stability of the generator and avoiding overheating damage.

(3)、一种风力发电机的限速冷却装置,通过设置摩擦缓速制动机构,从而使得螺纹推块不断的向转块处靠近,磁铁铰接块则开始逐渐带动摩擦块向固定块靠近并接触,从而通过摩擦块与固定块接触并摩擦,使得在小转杆转速过快使得螺纹推块拨动连接杆A较大角度的时候,自动通过摩擦块与固定块的摩擦对圆盘进行制动,圆盘同时对小转杆进行限速,进一步提升了对小转杆在超高转速下的自动限速效果,极大保护了发电机,避免了发电机长时间高负荷工作过热的问题出现。(3) A speed limiting cooling device for a wind turbine generator, which is provided with a friction slowing braking mechanism so that the threaded push block continuously approaches the rotating block, and the magnet hinge block gradually drives the friction block to approach and contact the fixed block, so that the friction block contacts and rubs with the fixed block, so that when the speed of the small rotating rod is too fast and the threaded push block moves the connecting rod A to a large angle, the disc is automatically braked by the friction between the friction block and the fixed block, and the disc limits the speed of the small rotating rod at the same time, further improving the automatic speed limiting effect of the small rotating rod at ultra-high speed, greatly protecting the generator, and avoiding the problem of overheating of the generator due to long-term high-load operation.

(4)、一种风力发电机的限速冷却装置,通过设置摩擦缓速制动机构,在磁铁铰接块靠近固定块的时候,通过磁铁铰接块与之间的磁吸力相吸,从而使得磁铁铰接块靠近磁铁并且通过磁性摆正磁铁铰接块正对固定块,保证了摩擦块与固定块贴合的紧密性以及摩擦的均匀度,进一步保证了对圆盘的制动效果。(4) A speed limiting cooling device for a wind turbine generator, which is provided with a friction slow-speed braking mechanism. When the magnet hinge block approaches the fixed block, the magnet hinge block is attracted by the magnetic attraction between the magnet hinge block and the fixed block, so that the magnet hinge block approaches the magnet and is aligned with the fixed block by magnetism, thereby ensuring the tightness of the fit between the friction block and the fixed block and the uniformity of the friction, and further ensuring the braking effect on the disc.

在使用时,在风吹动扇叶5带动转杆1进行转动的时候,转杆1在箱体2内壁转动并通过变速器6将低转速转换为高转速的小转杆7,高转速的小转杆7通过发电机8进行发电,同时在风力较大的时候,扇叶5的转速加快,小转杆7进行超高转速,从而使得发电机8进行超负荷工作,开始发热,此时,小转杆7外壁的圆盘301内部的螺纹推块303会因为小转杆7的超高速转速将其通过离心力甩出,并且此时甩动螺纹推块303的离心力大于弹性绳302的拉力,从而使得螺纹推块303会甩动并且通过螺纹推块303外壁的螺纹与圆盘301内壁的内螺纹螺纹进行旋转,从而在圆盘301内壁旋转并推出,从而使得螺纹推块303旋转推出至转块403处位置时,被转块403阻挡停止,同时此时的螺纹推块303转动四十五度,小扇叶304处于四十五度的旋转角度,从而通过小扇叶304四十五度角度继而吹动更多的风力对发电机8进行散热降温,并且可以在低转速时通过小扇叶304较小的倾斜角度,保证对发电机8进行小幅的吹风散热降温,继而针对小转杆7不同转速与发电机8不同的工作负荷下自动调整转速对发电机8进行降温冷却工作,同时在小扇叶304被推出后处于四十五度角度的时候,在对发电机8进行吹风散热的同时,小扇叶304也会受到较大的风阻,从而通过圆盘301带动小转杆7进行制动,对小转杆7与扇叶5进行一定的减速作用,对小转杆7进行了限速,同时也对发电机8的工作负荷进行了稳定,保证了发电机8的工作稳定性,避免过热损毁的情况出现,同时在螺纹推块303在圆盘301内壁旋转推出至转块403的时候,螺纹推块303会拨动连接杆A401,连接杆A401被拨动通过转块403带动连接杆B404旋转,弹性板402发生形变,连接杆B404拨动并且带动磁铁铰接块405至摩擦块407靠近固定块408,随着螺纹推块303不断的接触并拨动连接杆A401,从而使得螺纹推块303不断的向转块403处靠近,磁铁铰接块405则开始逐渐带动摩擦块407向固定块408靠近并接触,从而通过摩擦块407与固定块408接触并摩擦,使得在小转杆7转速过快使得螺纹推块303拨动连接杆A401较大角度的时候,自动通过摩擦块407与固定块408的摩擦对圆盘301进行制动,圆盘301同时对小转杆7进行限速,进一步提升了对小转杆7在超高转速下的自动限速效果,极大保护了发电机8,避免了发电机8长时间高负荷工作过热的问题出现,同时在磁铁铰接块405被连接杆B404带动旋转的时候,会被限位绳406进行拉动限位,避免其在旋转运动的时候磁铁铰接块405在连接杆B404一端旋转导致摩擦块407无法正对固定块408,同时在磁铁铰接块405靠近固定块408的时候,通过磁铁铰接块405与309之间的磁吸力相吸,从而使得磁铁铰接块405靠近磁铁409并且通过磁性摆正磁铁铰接块405正对固定块408,保证了摩擦块407与固定块408贴合的紧密性以及摩擦的均匀度,进一步保证了对圆盘301的制动效果,并且在小转杆7不进行超负荷工作的时候,连接杆A401被弹性板402的反弹力推回原位,从而使得磁铁铰接块405带动摩擦块407脱离固定块408,从而停止对固定块408的摩擦制动,最终完成对其的减速以及降温冷却效果。When in use, when the wind blows the fan blades 5 to drive the rotating rod 1 to rotate, the rotating rod 1 rotates on the inner wall of the box body 2 and converts the low speed into a high-speed small rotating rod 7 through the transmission 6. The high-speed small rotating rod 7 generates electricity through the generator 8. At the same time, when the wind is strong, the speed of the fan blades 5 is accelerated, and the small rotating rod 7 rotates at an ultra-high speed, so that the generator 8 is overloaded and starts to heat up. At this time, the threaded push block 303 inside the disk 301 on the outer wall of the small rotating rod 7 will be rotated at an ultra-high speed due to the ultra-high speed of the small rotating rod 7. The threaded push block 303 is quickly thrown out by centrifugal force, and at this time, the centrifugal force of the threaded push block 303 is greater than the pulling force of the elastic rope 302, so that the threaded push block 303 is swung and rotated through the threads of the outer wall of the threaded push block 303 and the internal threads of the inner wall of the disk 301, so that the inner wall of the disk 301 rotates and pushes out, so that when the threaded push block 303 is rotated and pushed out to the position of the rotating block 403, it is blocked by the rotating block 403 and stops. At the same time, the threaded push block 303 rotates forty-five degrees at this time, and the small fan blade 304 At a rotation angle of 45 degrees, more wind can be blown by the small fan blades 304 at a 45-degree angle to dissipate heat and cool the generator 8, and at a low speed, a small inclination angle of the small fan blades 304 can be used to ensure a small amount of blowing and cooling of the generator 8, and then the speed can be automatically adjusted according to the different speeds of the small rotating rod 7 and the different workloads of the generator 8 to cool the generator 8. At the same time, when the small fan blades 304 are pushed out and are at a 45-degree angle, while blowing and cooling the generator 8, the small fan blades 304 will also be subject to a large wind resistance, so that the small rotating rod 7 is driven by the disc 301 to brake, and the small rotating rod 7 and the fan blades 5 are decelerated to a certain extent, and the speed of the small rotating rod 7 is limited. At the same time, the workload of the generator 8 is stabilized, ensuring the working stability of the generator 8 and avoiding overheating and damage. At the same time, when the threaded push block 303 is rotated and pushed out to the rotating block 403 on the inner wall of the disc 301, the threaded push block 303 will toggle the connection Rod A401, connecting rod A401 is moved through the rotating block 403 to drive connecting rod B404 to rotate, the elastic plate 402 is deformed, and the connecting rod B404 moves and drives the magnet hinge block 405 to the friction block 407 close to the fixed block 408. As the threaded push block 303 continuously contacts and moves the connecting rod A401, the threaded push block 303 continuously approaches the rotating block 403, and the magnet hinge block 405 gradually drives the friction block 407 to approach and contact the fixed block 408, thereby When the rotation speed of the small rotating rod 7 is too fast and the threaded push block 303 moves the connecting rod A401 to a large angle, the friction between the friction block 407 and the fixed block 408 automatically brakes the disc 301, and the disc 301 limits the speed of the small rotating rod 7 at the same time, further improving the automatic speed limiting effect of the small rotating rod 7 at ultra-high rotation speed, greatly protecting the generator 8, and avoiding the problem of overheating of the generator 8 due to long-term high-load operation. When the magnet hinge block 405 is driven to rotate by the connecting rod B404, it will be pulled and limited by the limit rope 406 to prevent the magnet hinge block 405 from rotating at one end of the connecting rod B404 during the rotational movement, causing the friction block 407 to be unable to face the fixed block 408. At the same time, when the magnet hinge block 405 is close to the fixed block 408, the magnet hinge block 405 and 309 are attracted to each other through the magnetic attraction force between them, so that the magnet hinge block 405 is close to the magnet 409 and the magnet hinge is aligned by magnetic force. Block 405 is directly opposite to the fixed block 408, ensuring the tightness of the fit between the friction block 407 and the fixed block 408 and the uniformity of friction, further ensuring the braking effect on the disc 301, and when the small rotating rod 7 is not overloaded, the connecting rod A401 is pushed back to its original position by the rebound force of the elastic plate 402, so that the magnet hinge block 405 drives the friction block 407 to separate from the fixed block 408, thereby stopping the friction braking of the fixed block 408, and finally completing the deceleration and cooling effect on it.
