Steel rope retaining device for blade based on wind power generation

Abstract

The invention provides a steel rope retaining device for a blade based on wind power generation, relates to the technical field of wind power generation blade protection, and solves the problems that when the wind receiving degree of the blade is controlled in the prior art, the turning direction of the blade is adjusted or a speed reduction set is adopted to avoid the galloping phenomenon caused by wind receiving of the blade mostly, although the rotating speed of the blade can be controlled, the problem of blade self swing caused by air blowing cannot be avoided. A bottom plate is embedded into the bottom end of a main body, side plates are further fixedly connected to the front side and the rear side of the top end face of the bottom plate, rotating shafts are further rotatably connected to the interiors of the side plates, and the two rotating shafts are fixedly connected to the bottom side positions of the front end face and the rear end face of a supporting column correspondingly; and the supporting column is rotationally connected to the inner sides of the two side plates through the rotating shafts fixedly connected to the front side and the rear side, the top end of the supporting column is connected with the top end face of the interior of the main body, the fixed connecting end of the supporting column and the main body is the end, away from a generator body, of the wind power blade, and the bottom end of the supporting column is further of a structure hinged to the bottom plate.

Description

technical field [0001] The invention belongs to the technical field of blade protection for wind power generation, and more specifically relates to a steel rope holding device for blades based on wind power generation. Background technique [0002] Wind power generation refers to the conversion of wind kinetic energy into electrical energy, and the setting of blades directly affects the conversion efficiency of wind energy and its annual power generation. It is an important part of wind energy utilization. Blades will sway violently in bad weather, and blades The violent swing of the blade will cause tearing of the blade, resulting in economic loss The existing wind power blade protection devices still have the following deficiencies: 1. When controlling the degree of wind exposure of the blades, it is mostly to adjust the steering of the blades or use a deceleration group to avoid the speeding phenomenon of the blades caused by the wind. Although it can control the rotat...

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides a steel rope holding device for blades based on wind power generation, so as to solve the problem of adjusting the steering of the blades or adopting a deceleration group to avoid the The speeding phenomenon caused by the wind can control the rotation speed of the blades, but it cannot avoid the self-swaying of the blades caused by the wind. The self-swaying of the blades will not only cause damage to the body of the wind turbine, but also cause damage to the blades The problem of damage caused by swinging to the blade body
