Wind energy conversion device for pasturing area

Abstract

The invention discloses a wind energy conversion device for a pasturing area. The wind energy conversion device comprises a supporting table and a folding unit. Mounting holes are formed in the top and the bottom of the supporting table in an equidistant circumferential array mode, a circular through groove is formed in the center of the supporting table, an air duct unit is arranged over the circular through groove, a rotating unit is fixedly installed at the top of the air duct unit, and a first wind energy conversion unit is arranged in the air duct unit; the wind energy conversion device for the pasturing area is small in occupied area, convenient to install, low in practical cost and high in wind energy conversion efficiency, small wind power can be pressurized and utilized, the operation quality of the wind energy conversion device is greatly improved, meanwhile, flying animals are not prone to being hurt, ice layers and ice blocks covering the fan blades can be cleaned in winter with the low air temperature, and the wind energy conversion device is convenient to use. And meanwhile, the fan blades can be retracted into the device, so that the fan blades and the wind energy conversion device can be effectively protected.

Description

technical field [0001] The invention relates to the technical field of wind energy conversion, in particular to a wind energy conversion device for pastoral areas. Background technique [0002] Wind energy is the kinetic energy generated by a large amount of air flow on the earth's surface. Due to the different changes in temperature and the content of water vapor in the air after the ground is irradiated by the sun, the air pressure in different places is different, and the high-pressure air flows in the horizontal direction to the low-pressure area. form wind; [0003] The main application areas of wind energy conversion devices are in rural areas, pastoral areas, mountainous areas, large, medium and small cities under development or near commercial areas to meet the needs of local users. Wind power generation technology has the characteristics of clean and pollution-free. The development strategy has a driving effect. However, most of the existing wind energy conversion ...

AI Technical Summary

Problems solved by technology

[0003] Wind energy conversion devices are mainly used in rural areas, pastoral areas, mountainous areas, and built near developing large, medium, and small cities or commercial areas to meet the electricity demand of local users. The development strategy has a driving effect. However, most of the existing wind energy conversion devices used in pastoral areas use horizontal axis wind energy conversion devices, and some large horizontal axis wind energy conversion devices have a relatively complicated structure and occupy a large area. The blade structure is relatively large, and the installation cost is high. The blades on the wind energy conversion device are exposed high-speed rotating parts. The larger blades are easy to hurt some flying animals such as birds. Some small horizontal axis wind energy conversion devices are heavier Small, easy to be blown down or even blown away by strong winds, and it is not easy for the wind energy conversion device to operate due to the small wind force;

[0004] When using wind energy conversion devices in pastoral areas with higher altitudes and latitudes, the local temperature is low and the humidity is high in winter, which may easily lead to ice-covered blades of the wind energy conversion device. When the blades are covered with ice, The height of the blade surface is uneven, which will easily increase the load and resistance of the blade, thus affecting the operation quality of the wind power conversion device. When the ice is severe or encounters some extreme weather, the wind blade cannot be effectively protected, and the wind energy conversion The blades of the device and the conversion device are damaged. Therefore, we propose a wind energy conversion device for pastoral areas
