Self-variable blade angle wind turbine

Abstract

A wind power generator with a self-variable fan blade angle comprises mandrel flanges, torsion springs, conical mandrels, fan blades, fan blade rib plates, assembly holes, torsion spring fixing end holes, torsion spring movable end screw holes, bearing lock caps and lock cap dowels; the fan blades are connected to a main mandrel of the wind power generator by the mandrel flanges, the torsion springs are arranged at the ends, close to the mandrel flanges, of the conical mandrels, a fan blade root part conical roller bearing is arranged at the front end of each torsion spring, one torsion spring fixing end hole is formed in the front end part of the conical mandrel slightly behind each fan blade root part conical roller bearing, one torsion spring movable end screw hole is formed in the conical mandrel at the rear end of each torsion spring, one fan blade rib plate is connected to the outer end of each conical mandrel, and one assembly hole is formed in each fan blade rib plate. A fan blade tail end conical roller bearing is arranged at the position of the rear end, close to the inside, of the conical mandrel behind each fan blade rib plate; one bearing lock cap is arranged at the outer end port of each fan blade tail end conical roller bearing. The wind power generator with the self-variable fan blade angle is simple in integral structure, convenient to mount, use and operate, good in stability and high in reliability.

Description

technical field [0001] The invention relates to a wind power generator device, in particular to a self-variable wind blade angle wind power generator. Background technique [0002] In the wind generator of known technology, the angle of the blades is fixed. In order to resist super-strong wind, the area and angle of the wind blades for collecting wind are greatly restricted. Therefore, the power generation capacity of the fan is reduced, and the ability to resist strong winds is also limited. restricted to a certain extent. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a self-variable blade angle wind generator, which is a wind generator that can automatically change the blade angle according to the wind speed. Under certain conditions, the windward angle of the wind blades will automatically increase, so more wind energy can be obtained; under high wind speed conditions, the windward a...
