Vertical-axis wind-driven generator

Abstract

The invention provides a vertical-axis wind-driven generator and belongs to the technical field of wind power generation. The vertical-axis wind-driven generator comprises a base, a generator body arranged in the base, a stand column arranged on the upper side of the base and blade assemblies. A round disk is arranged at the center of the top of the stand column. A plurality of connection rods arearranged around the center of the round disk and penetrate through the round disk. Each blade assembly is in an arc curved face and comprises an upper blade, a lower blade and a connection portion, wherein the upper end and the lower end of the connection portion are fixedly connected with the upper blade and the lower blade correspondingly, the end, far away from the connection portion, of the upper blade and the end, far away from the connection portion, of the lower blade are provided with an upper sliding block and a lower sliding block correspondingly, the upper sliding block and the lower sliding block are connected with the upper end and the lower end of the corresponding connection rod in a sliding manner, and the upper sliding block and the lower sliding block are fixedly connected with the connection portion through soft elastic rubber pieces. The vertical-axis wind-driven generator is simple in structure, convenient to use and capable of reducing the air resistance and resisting strong wind force, the efficiency of the vertical-axis wind-driven generator is improved, and the service life of the vertical-axis wind-driven generator can be prolonged.

Description

Technical field [0001] This application relates to the technical field of wind power generation, and in particular to a vertical axis wind power generator. Background technique [0002] Wind energy is a kind of resource-rich, green and environmentally friendly renewable energy. Its utilization conditions are relatively less restricted and its prospects are broad. In the current situation where the demand for electric energy is constantly tight, wind power generation will be an important way for mankind to obtain electric energy. Compared with thermal power, water power, and solar power generation, wind power has many advantages such as economy and easy realization. However, because the wind energy utilization technology is not mature enough and the wind energy utilization rate and conversion rate are not high, the main constraint is the low energy efficiency ratio of wind turbine blades. Therefore, the scientific design of the wind turbine blade determines the efficiency of the...
