Problems solved by technology

Therefore, this kind of wind generator must be installed with a set of complicated regulators to control the wind speed, which will seriously affect the utilization of wind energy.
This is due to the installation of a regulator to control the wind speed, which increases the load on the wind turbine and reduces the efficiency of wind power generation.

Embodiment Construction

[0018] As shown in the accompanying drawings, the size of the required power generation and the size of its blades are determined according to the surrounding environment of the wind power generator. The wind consumption windows 3 are provided with 10 pieces (also can be more), are arranged in sequence to form a trapezoidal shape, and are installed in the middle area of ​​the fan blade frame 2 . Both side edges of each wind consumption window are connected with the blade frame by springs or elastic sheets. Choose a spring or elastic sheet with appropriate elastic force. The area ratio of the area of ​​the wind consumption window 3 and the fan blade is 3 / 6-5 / 6 better. 2-4 blades are installed on the generator wind wheel 1 at equal angles, and the generator 6 is fixed on the fan column frame 8 by connecting the wind vane 5 and the rotating bearing 7, and the column frame is fixed on the ground.

Abstract

The invention relates to a blade of airscrew wind generator, which is in the structure of wind-consumption window formed by a plurality of blades and the wind-consumption window is connected to the blade frame via spring (plate). The inventive wind blade generator can automatically adjust the rotational speed to balance the output voltage, and even the wind power is weaker, it can rotate the airscrew. Its minimum start wind force is 1.5 level and the maximum bearing wind is 11 level.

Description

technical field [0001] The present invention relates to yet another wind power generation device, in particular to a wind blade structure for automatically adjusting the size of the windward section of a propeller type wind power generator. Background technique [0002] The propeller type wind generator utilizes the wind energy in nature to convert it into electrical energy, and the wind blades can be rotated to generate electricity when the wind is strong or weak. At present, the voltage generated by propeller-type wind generators on the market increases or decreases with the change of wind energy, and the output voltage is unstable. When the wind speed is low, the propeller type wind impeller rotates slowly, or even does not rotate. And when the wind speed is high, the wind impeller rotates very fast, so the voltages sent out are just very different. Therefore, this kind of wind generator will be installed with a set of complicated regulators to control the wind speed, w...
