Blade damping device for wind driven generator

Abstract

The invention provides a blade damping device for a wind driven generator. The blade damping device comprises a fixed seat, a telescopic base, a front transmission shaft, telescopic guide plates, a supporting frame, a bracket, a damping clamp, a rear chain wheel set and a driving device, wherein wherein the fixed seat is fixedly connected to the upper portion of a consigning table; the bottom faceof the telescopic base is fixedly connected with the upper surface of the consigning table; the front transmission shaft is rotationally connected to the rear side of the upper portion of the telescopic base through a bearing; the two ends of the rear chain wheel set are rotationally connected to the front side of the upper portion of the telescopic base through bearings; driving chain wheels onthe two sides of the front transmission shaft are connected with chain wheels on the rear chain wheel set through chains; the two telescopic guide plates are movably connected into sliding rails on the two sides of the telescopic base; the lower end of the bracket is movably connected to the front ends of the telescopic guide plates through hinge pieces; and an adjusting claw plate clamps the tailor the middle position of a wind power blade, the wind power blade is clamped in an assisted manner, and the situation that due to the too large vibration amplitude, the wind power blade is prone toswinging violently, and accidental scratching or breaking is prone to happening is reduced.

Description

technical field [0001] The invention belongs to the technical field of wind power blade transportation, and more specifically relates to a blade damping device for a wind power generator. Background technique [0002] A wind turbine is a device that converts wind energy into electrical energy, and is mainly composed of blades, generators, mechanical components and electrical components. According to the different rotation axes, wind turbines are mainly divided into two types: horizontal axis wind turbines and vertical axis wind turbines. At present, horizontal axis wind turbines occupy the mainstream position in the market. The principle of wind power generation is to use the wind to drive the windmill blades to rotate. , and then increase the speed of rotation through the speed increaser to promote the generator to generate electricity. According to the current windmill technology, power generation can start at a breeze speed of about three meters per second. The function ...

Problems solved by technology

[0005] In order to solve the above technical problems, the present invention provides a blade damping device for wind power generators to solve the problem that the similar wind power blade vehicles in the above patents lack equipment for fixing the tail ends of the blades, and the transport vehicles are transported on mountain roads during the transportation of wind power blades. Due to the factors of the road surface, it is very easy to vibrate. If the vibration amplitude is too large, it will easily cause the wind turbine blade to swing violently, and it is easy to accidentally scratch or break the problem.
