Vertical-axis wind power generation apparatus

Abstract

The invention discloses a vertical-axis wind power generation apparatus. The vertical-axis wind power generation apparatus comprises a fan rod, wherein a power generator is arranged on the top end of the fan rod; a pneumatic device is arranged on the top end of a power generator rotor of the power generator; the pneumatic device comprises an impeller shaft connected with the top end of the power generator rotor; two upper supporting plates which are perpendicular to each other are arranged on the upper end of the impeller shaft; two lower supporting plates which are perpendicular to each other are arranged on the lower end of the impeller shaft; blades are arranged between the upper supporting plates and the lower supporting plates, and the blades are connected with the upper supporting plates and the lower supporting plates through a blade adjusting shaft; the blade adjusting shaft comprises an adjusting shaft cover and an adjusting column fixed on the lower end surface of the adjusting shaft cover; a pawl-and-ratchet mechanism is arranged on the power generator rotor and comprises a pawl arranged on the power generator rotor and a ratchet which is engaged with the pawl and provided with a gear; a gear which is engaged with the ratchet is arranged outside the ratchet and is connected with a driving shaft of a driving motor through keys. The vertical-axis wind power generator apparatus is simple in structure, capable of realizing the controllability of the pneumatic device and high in power generation efficiency, and the impeller and the wind direction angle are adjustable.

Description

technical field [0001] The invention relates to a wind power generating device, in particular to a vertical axis wind power generating device. Background technique [0002] Utilizing the inexhaustible and inexhaustible wind energy in nature to generate electricity is the most economical and feasible power supply method in windy areas, especially remote areas. With the development of modernization in all countries in the world, the demand for energy is increasing, while the supply of energy is becoming more and more tense. Governments of various countries are also starting to develop new energy sources, hoping to change from traditional energy sources to green energy sources, while wind power and Solar power is an economical and environmentally friendly green energy, which is increasingly recognized and accepted by people. [0003] Wind turbines are divided into horizontal and vertical types according to the installation direction of the impeller shaft. The horizontal wind t...

AI Technical Summary

Problems solved by technology

[0003] Wind turbines are divided into horizontal and vertical types according to the installation direction of the impeller shaft. The horizontal wind turbine has a complex structure but high power generation efficiency. The vertical wind turbine has a relatively simple structure and high overall structural stability but low power generation efficiency.

In the current wind power generation device, the positional relationship between the impeller and the wind direction is fixed, which cannot be adjusted artificially, and the power generation efficiency is low
