Windmill and wind power generator composed of the same

Abstract

The invention relates to a windmill, comprising a wind wheel which is formed from a horizontal rotating shaft (1) and vanes (3). The vane is swingly borne on a vane shaft (2) which is vertically fixed on the horizontal rotating shaft. The vane shaft leans to a side of the vane. A vane swinging limit apparatus is arranged on the horizontal rotating shaft or on the vane shaft. The vane shaft is perforated in the vane shaft hole. A radial convex (5) is arranged on the vane shaft. A radial groove (6) or a limit block (4) is arranged on the corresponding vane shaft hole. The limit block (4) is fixed on the horizontal rotating shaft or on the vane shaft and protrudes into both sides of the vane. The vane and the vane shaft are slidingly matched and connected with each other through an extension spring (10). The vane can automatically swing to proper obliquity according to wind from the front or from the back, so that the windmill bears homodromous torque whether the wind blows to the vane from the front or from the back. In the wind power generation device comprising the windmill, a plurality of windmills are arranged the corresponding numbers of horizontal air holes (8) on a vertical wall (7). The vertical wall integrates the wind power, increases the wind power passing the wind tunnel, and improves the power generation capability of the windmill.

Description

technical field [0001] The invention relates to a windmill and a wind power generating device composed of the windmill. Background technique [0002] A windmill, also called a wind turbine, is a power machine that uses wind as energy without fuel. Wind turbines are mainly composed of wind energy receiving devices, control mechanisms, transmissions, supports, etc. Conventional wind turbines with wind rotors as wind energy receiving devices can be divided into two types: horizontal axis structure and vertical axis structure. The wind wheel is mainly composed of a rotating shaft and a blade group. The blades of the existing horizontal rotating shaft wind wheel are mostly directly fixed on the horizontal rotating shaft. The blades are not in the same plane, but slightly inclined to the vertical plane, with a fixed inclination angle. In this way, the windmill can only rotate against the wind, and the direction of inclination determines the direction of rotation of the windmill w...

Problems solved by technology

The disadvantage of this fixed-inclination blade is that when the wind blows from the rear, the torque on the windmill is opposite to the direction in which the windmill rotates against the wind. If the upper side is tilted backward, the windmill will turn clockwise when the wind blows from front to back; if the tilt angle is reversed, the steering will also be reversed, but at the same tilt angle, if the wind blows from back to front, the windmill will turn counterclockwise. When the windmill is clockwise

In addition, due to the uneven wind speed caused by the wind force, the generator will be affected to a certain extent.
