Wind driven generator with telescopic blade

Abstract

The invention discloses a wind driven generator with a telescopic blade. The wind driven generator with the telescopic blade comprises a support, wherein a fan rotary shaft, a rotary unit, a generation unit and the telescopic blade are arranged on the support; the fan rotary shaft is connected with the generation unit; the telescopic blade is rotatably connected with the fan rotary shaft through the rotary unit; a control unit is arranged in the support; and the generation unit, the rotary unit and the telescopic blade are connected with the control unit. According to the wind driven generatorwith the telescopic blade provided by the invention, through designing the telescopic blade and the rotary unit, the problems of transportation and installation are solved; meanwhile, during use, thelength of the telescopic blade can be adjusted according to the air volume, so that the rotation speed of the blade is prevented from being too fast; and meanwhile, under a high wind and even a typhoon, the telescopic blade can be rotated until a plane of the telescopic blade to be parallel to a wind direction through the rotary unit, so that a wind area is reduced, the blade and the wind drivengenerator are prevented from being damaged by the high wind, the service life of the wind driven generator is prolonged, and the wind driven generator has a broad market prospect and a broad application prospect.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generator with telescopic blades. Background technique [0002] With the development of society, the depletion of traditional energy, and the increasing environmental pollution, we urgently need some new energy to solve the human energy crisis. As a clean energy, wind energy has the advantages of being environmentally friendly, non-polluting, and inexhaustible. The wind power generator is a power device that converts wind energy into mechanical energy and mechanical energy into electrical energy. The existing wind power generator has the following disadvantages: the blades are too long, and it is difficult to transport and install. Even in typhoon weather, the area exposed to the wind is too large, causing damage to the blades and even the entire wind turbine. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the presen...
