Problems solved by technology

At present, the single-blade horizontal-axis wind turbine is the most widely used in the market. In order to improve the utilization rate of energy, obtain more power generation in the same wind environment, and make full use of energy, but in fact, the single-blade horizontal-axis Wind turbines are still not efficient in generating electricity, so a new technology is needed to improve the efficiency of wind power

Abstract

The invention discloses a double-impeller type horizontal-axis wind turbine. The double-impeller type horizontal-axis wind turbine comprises two impellers, a supporting base, a tower, a hollow shaft, a solid shaft and two electric generators. The two impellers are symmetrically installed on the left side face and the right side face of the supporting base through bearings. The solid shaft is installed inside the hollow shaft through a bearing. The periphery of the hollow shaft is installed inside the tower through a bearing. The supporting base is installed at the top of the tower, and the tower serves as a supporting piece of the whole device. The top of the hollow shaft and the top of the solid shaft are installed at the inner bottom and the top of the supporting base through bearings correspondingly. The top of the hollow shaft and the top of the solid shaft are each provided with a big bevel gear. An impeller shaft of each impeller is provided with a small bevel gear which are in engaged transmission with the two big bevel gears at the same time. The hollow shaft and the solid shaft are connected with the corresponding electric generators at the bottom of the tower. According to the double-impeller type horizontal-axis wind turbine, the front impeller and the rear impeller generate electricity at the same time, wind capturing capacity of the wind turbine is improved, generated power is greatly increased, the utilization rate of wind energy is also increased, and the application prospects are good.

Description

technical field [0001] The invention belongs to the field of wind power generation, and relates to a horizontal-axis wind power generator, in particular to a double-blade horizontal-axis wind power generator. Background technique [0002] With the rapid development of the social economy, the demand for energy is also increasing rapidly. The current energy structure is still dominated by fossil energy. Hope to find a clean energy to replace fossil energy. As a renewable clean energy, wind energy is inexhaustible, and wind energy reserves are abundant in our country, so wind power generation has also developed rapidly. The currently used wind turbines mainly include horizontal-axis wind turbines and vertical-axis wind turbines. Compared with vertical-axis wind turbines, horizontal-axis wind turbines have more mature technology, greater power generation, and higher wind energy conversion efficiency. At present, the single-blade horizontal-axis wind turbine is the most widely ...
