Wind-driven generator blade provided with buffering mechanism and electric braking mechanism

Abstract

The invention discloses a wind-driven generator blade provided with a buffering mechanism and an electric braking mechanism, and belongs to the technical field of wind-driven generators with vertical shafts. According to the technical scheme, the wind-driven generator blade comprises a frame assembly, and a blade assembly arranged in the frame assembly, wherein a buffering mechanism assembly comprising slide block rails is arranged between the frame assembly and the blade assembly; slide rod bases are arranged on the slide block rails, and slide rods are arranged on the slide rod bases; elastic parts pass through the two ends of the slide rods; slide blocks are arranged between the elastic parts; pull rod bases are arranged on side frames of the frame assembly; a pull rod is arranged between each pull rod base and the corresponding slide block. The wind-driven generator blade provided with the buffering mechanism and the electric braking mechanism has the beneficial effects that the blade rotating range can be limited through the buffering mechanism, so that blades and a frame can be prevented from being impacted and deformed, and the noise pollution can be reduced; if the wind speed is beyond the speed for generating electricity, a solenoid valve can perform braking to control some blades to stop doing work and enable the blades to be kept in fixed wind releasing positions.

Description

technical field [0001] The invention relates to the technical field of vertical axis wind power generation, in particular to a wind generator blade with a buffer mechanism and an electric control brake mechanism. Background technique [0002] When the blades of the vertical-axis resistance wind turbine are rotated by the wind to do work, they often collide with the frame, causing deformation of the frame or blades, and the sound generated by the collision will cause noise pollution. When the wind speed reaches the limit wind speed set by the blades, if the blades without protection mechanism continue to work at full load, there will be safety hazards and easy damage, which will reduce the power generation efficiency of the wind turbine. Contents of the invention [0003] In order to solve the deficiencies of the above-mentioned technology that has never been used in the world, the purpose of the present invention is to provide a windshield with a buffer mechanism that can ...
