Strong wind resisting type vertical-axis wind-driven generator

Abstract

The invention provides a strong wind resisting type vertical-axis wind-driven generator, and belongs to the technical field of wind-driven generation. The strong wind resisting type vertical-axis wind-driven generator comprises a base, a generator body which is arranged in the base, a vertical column and a blade assembly, wherein the vertical column and the blade assembly are arranged above the base; the blade assembly is a circular arc shaped curved surface; a disc is arranged in the center of the top part of the vertical column; a plurality of connecting rods are arranged around the center of the disc in a penetrating manner; an upper sliding block and a lower sliding block correspondingly sleeve the upper end and the lower end of each connecting rod and are correspondingly hinged with the upper end and the lower end of the blade assembly; the upper sliding blocks and the lower sliding blocks are correspondingly fixedly connected to the middle part of the blade assembly through softelastic rubber parts; an upper stopping block and a lower stopping block are correspondingly arranged at the upper end and the lower end of each connecting rod; three sliding chutes are uniformly formed in the outer side surfaces of the connecting rods; lubricating oil devices which communicate with the sliding chutes are arranged in the upper stopping blocks; bumps which are corresponding to thesliding chutes are arranged on the upper sliding blocks and the lower sliding blocks. The strong wind resisting type vertical-axis wind-driven generator is capable of reducing air resistance, resisting strong wind, improving the efficiency, and prolonging the service life.

Description

technical field [0001] The present application relates to the technical field of wind power generation, in particular to a vertical axis wind power generator resistant to strong winds. Background technique [0002] Wind energy is a resource-rich, green and environmentally friendly renewable energy with relatively few restrictions on its utilization conditions and broad prospects. In the current situation where the demand for electric energy is constantly tense, wind power generation will be an important way for human beings to obtain electric energy. Compared with thermal power, hydraulic power, and solar power, wind power generation has many advantages such as economy and easy realization. However, due to the immaturity of wind energy utilization technology, the utilization rate and conversion rate of wind energy are not high, and the main constraint factor is the low energy efficiency ratio of wind turbine blades. Therefore, the scientific design of fan blades determines...
