Weathercock-less windmill

Abstract

The purpose of the patent of the present invention is to provide a new windmill without a wind vane. Its principle is to mechanically fix four cross arms extending out to the four sides with the same length at positions equally divided on a main vertical shaft. In the same direction of each cross arm, fix the vertical shafts of the fan blades with the same spacing, the same number, and the same specifications, and fix the rotatable fan blades on the vertical shafts of the fan blades. The range of motion of the fan blades is controlled by the buffer to be horizontal and vertical to the cross arm. 1 / 4 of the arc range. All movable fan blades accept the pressure of wind on the front when meeting wind coming from different directions, some slopes accept the pressure of wind, and some go along with the wind. At the same time, according to the size of the wind force, the wind blade surface on the wind blade can be expanded or closed, so that a controllable wind turbine with strong wind-catching ability and capable of being put into practical use can be obtained. The rotatable and controllable wind blades of the non-weather windmill increase the practicability of the non-weather windmill and avoid the situation that the windmill cannot be controlled due to excessive wind force.

Description

Technical field: [0001] The patent of the present invention relates to a power device utilizing wind energy. Because of its special working method, it can utilize wind energy from different directions, and at the same time, it can effectively control the captured wind energy and improve the utilization rate of wind energy. Background technique: [0002] At present, the wind turbines used in my country's existing wind power generation all adopt traditional three-blade or two-blade wind turbines with wind vanes to drive power generation equipment. As everyone knows, the best way for windmills to improve the utilization rate of wind energy is: (1) the incoming wind from any side can be utilized; 3) The wind-capturing capacity of the windmill should be effectively controlled. However, the traditional windmills commonly used now must use wind vanes to find the direction of the wind, consuming part of the wind energy. The wind-receiving surface of the blade must have an included...
