Description

Technical Field

[0001] The present invention relates to the technical field of wind power generation devices, and in particular to a deceleration buffer mechanism of a wind power generation device capable of tracking wind direction. Background Art

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. During operation, the speed of a wind turbine increases with the increase of wind speed. When the wind speed is too high, the generator may generate too much electricity, causing the coil temperature to rise and burn the generator, or the current to be too large and damage the downstream equipment.

[0003] In order to prevent the generator from being damaged when the wind is strong, it is necessary to protect the generator. The current protection method is generally to set a brake device inside the wind turbine. When the existing brake device decelerates the rotating wind turbine, the wind turbine will hit the brake device. The brake device is easily damaged and loosened after being hit for a long time, thereby reducing the deceleration performance of the brake device. Summary of the invention

[0032] The brake component 7 includes a brake ring 10 which is fixedly connected to the inner wall of the protective frame 3. A friction ring 12 is fixedly connected to the surface of the rotating rod 6. Positioning blocks 16 are arranged at the ends of the brake ring 10 and the friction ring 12 which are close to each other. A round rod 14 is slidably connected to the inner wall of the positioning block 16. One end of the round rod 14 away from the positioning block 16 is a brake pad 13. A spring 11 is fixedly connected to the surface of the positioning block 16. An arc-shaped frame 15 is hinged to the surface of the brake pad 13. An elastic piece 19 is fixedly connected to the inner wall of the arc-shaped frame 15. When the present invention needs to decelerate and protect the generator 5, the extrusion component 8 is used to push the brake pad 13 to move towards the surface of the brake ring 10. When the brake pad 13 moves, it squeezes the arc-shaped frame 15 to deform. When the arc-shaped frame 15 contracts, it pulls the two brake pads 13 to move closer to each other. At the same time, it squeezes the round rod 14 to move towards the inside of the positioning block 16. The round rod 14 is used to improve the stability of the brake pad 13 when squeezing the friction ring 12. When the brake pad 13 moves, it pushes the friction plate 18 to contact the surfaces of the brake ring 10 and the friction ring 12, so as to frictionally squeeze the rotating rod 6 by the friction ring 12 to achieve the purpose of decelerating the generator 5. The method of using friction deceleration can avoid the impact of the rotating rod 6 and prevent the brake component 7 from being damaged. At the same time, the force of the extrusion component 8 can be used to push the brake pad 13 to slowly contact the friction ring 12 to avoid the brake pad 13 being violently impacted during operation. Circular grooves 20 are respectively formed at the ends of the brake ring 10 and the friction ring 12 which are close to each other.

[0036] The extrusion member 8 includes a fixed disk 30, which is fixedly connected to the inner wall of the protective frame 3. A circular hole 31 is formed on the surface of the fixed disk 30, and an electric push rod 32 is fixedly connected to the inner wall of the circular hole 31. When the present invention needs to decelerate the generator 5, the electric push rod 32 is used to push the brake pad 13 towards the surface of the brake ring 10, thereby improving the convenience of the brake member 7 during operation. A plurality of brake pads 13 are arranged inside the brake ring 10, and the four electric push rods 32 can simultaneously push the plurality of brake pads 13 to work synchronously. The plurality of brake pads 13 are used to squeeze and rub the friction ring 12, and at the same time, the impact force received by the brake pads 13 can be dispersed, improving the use effect of the brake pads 13. The output end of the electric push rod 32 is fixedly connected to the surface of the brake pad 13.

[0037] The fixed disk 30 is arranged at one end close to the generator 5, the circular hole 31 is located at one end of the fixed disk 30 away from the generator 5, and the number of electric push rods 32 is four. The four electric push rods 32 are arranged in a circumferential manner with the fixed disk 30 as the center.

[0038] The deceleration member 9 includes a rotating ring 40. The number of rotating rings 40 is two. The mutually remote ends of the two rotating rings 40 are respectively fixedly connected to the fixed disk 30 and the brake pad 13. A triangular frame 42 is slidably connected to the surface of the rotating ring 40. A vertical frame 41 is hinged at the center of the triangular frame 42. An elastic rod 46 is fixedly connected to the end of the vertical frame 41. The end of the elastic rod 46 away from the vertical frame 41 is fixedly connected to a bent frame 43. When the brake pad 13 of the present invention moves, the triangular frame 42 is pulled by the rotating ring 40 to deform. At the same time, the triangular frame 42 will push the elastic rod 46 towards the surface of the rotating rod 6 through the vertical frame 41. When the elastic rod 46 moves, it will push the arc pressure block 45 through the bent frame 43 to squeeze the surface of the rotating rod 6, and further improve the deceleration and protection effect on the generator 5 through the arc pressure block 45. An arc pressure block 45 is fixedly connected to the end of the bent frame 43 away from the elastic rod 46, and a deep groove 44 is formed on the surface of the rotating rod 6.

[0040] When in use, when deceleration protection is required for the generator 5, the squeezing member 8 is used to push the brake pad 13 to move towards the surface of the brake ring 10.

At the same time, it squeezes the round rod 14 to move towards the inside of the positioning block 16. The round rod 14 is used to improve the stability of the brake pad 13 when squeezing the friction ring 12. When the brake pad 13 moves, it pushes the friction plate 18 to contact the surfaces of the brake ring 10 and the friction ring 12, so as to use the friction ring 12 to frictionally squeeze the rotating rod 6, achieving the purpose of decelerating the generator 5. The method of using friction deceleration can avoid the impact of the rotating rod 6 and prevent the brake component 7 from being damaged. At the same time, the strength of the squeezing member 8 can be used to push the brake pad 13 to slowly contact the friction ring 12, avoiding the brake pad 13 from being violently impacted during operation. When deceleration is required for the generator 5, the electric push rod 32 is used to push the brake pad 13 to move towards the surface of the brake ring 10, thereby improving the convenience of the brake component 7 during operation. A plurality of brake pads 13 are arranged inside the brake ring 10, and the four electric push rods 32 can simultaneously push the plurality of brake pads 13 to work synchronously. The plurality of brake pads 13 are used to squeeze and friction the friction ring 12, and at the same time, the impact force received by the brake pads 13 can be dispersed, improving the use effect of the brake pads 13. When the brake pad 13 moves, it pulls the triangular frame 42 to deform through the rotating ring 40. At the same time, the triangular frame 42 will push the elastic rod 46 towards the surface of the rotating rod 6 through the vertical frame 41.
