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

[0006] Furthermore, one end of the rotating rod away from the generator passes through the protective frame and extends to the outer end of the protective frame, and the fan blade is arranged at the outer end of the protective frame.

[0007] Furthermore, two slides are provided on the surface of the positioning block, and the two slides are symmetrically arranged with the positioning block as the center. The surface of the slide is slidably connected to the inner wall of the annular groove, the center of the arc frame is hinged, and the end of the spring away from the positioning block is fixedly connected to the surface of the brake pad.

[0008] Furthermore, the end of the round rod passes through the positioning block and extends to the outer end of the positioning block. Two round rods are arranged on the surface of the positioning block, and the two round rods are symmetrically arranged with the positioning block as the center.

[0009] Furthermore, the extrusion component includes a fixed plate, which is fixedly connected to the inner wall of the protective frame. A circular hole is opened on the surface of the fixed plate, and an electric push rod is fixedly connected to the inner wall of the circular hole. The output end of the electric push rod is fixedly connected to the surface of the brake pad.

[0010] Furthermore, the fixing disk is arranged at one end close to the generator, the circular hole is located at one end of the fixing disk away from the generator, and the number of the electric push rods is four, and the four electric push rods are arranged in a circle with the fixing disk as the center.

[0011] Furthermore, the deceleration component includes a rotating ring, and there are two rotating rings. The ends of the two rotating rings that are away from each other are respectively fixedly connected to the fixed disk and the brake pad. The surface of the rotating ring is slidably connected to a tripod, and the center of the tripod is hinged with a vertical frame. The end of the vertical frame is fixedly connected to an elastic rod, and the end of the elastic rod away from the vertical frame is fixedly connected to a bent frame, and the end of the bent frame away from the elastic rod is fixedly connected to an arc pressure block, and a deep groove is provided on the surface of the rotating rod.

A plurality of brake pads are arranged inside the brake ring, and four electric push rods can simultaneously push the plurality of brake pads to work synchronously. The friction ring is squeezed and rubbed by the plurality of brake pads, and the impact force on the brake pad can be dispersed at the same time, thereby improving the use effect of the brake pad. When the brake pad of the present invention moves, the tripod is pulled by the rotating ring to produce deformation. At the same time, the tripod pushes the elastic rod to move toward the surface of the rotating rod through the vertical frame. When the elastic rod moves, the arc pressure block is pushed by the curved frame to squeeze the surface of the rotating rod. The arc pressure block further improves the deceleration protection effect on the generator. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
