Problems solved by technology

This type of structure is not limited by the wind direction, and the rotation is relatively stable, but there are problems of small driving force and large overall wind resistance, so it is generally used for sensing wind speed, but not for power output.

Abstract

The invention provides a streamline wind collection device. The streamline wind collection device is characterized by comprising a hub, M supporting rods and N wind buckets, wherein the M supporting rods are uniformly arranged on the outer periphery of the hub in a radial mode, N wind buckets are sequentially arranged on each supporting rod from outside to inside and form N wind bucket sets, each wind bucket is of a hollow and streamline curved surface structure with a windward port in the peripheral direction of the hub, streamline curved surfaces are gradually contracted to form closed curved surfaces from the windward ports, M is greater than or equal to 3, and N is greater than or equal to 1. According to the streamline wind collection device, the compound streamline wind buckets replace wind cups, and therefore the resistance of wind power in various directions acting on the back surfaces of the wind buckets can be reduced, the driving force of the device can be increased, the whole wind resistance can be lowered, and the wind collection efficiency can be improved.

Description

technical field [0001] The invention relates to the field of wind energy utilization, in particular to a streamlined wind collection device. Background technique [0002] There are mainly two ways to convert wind energy into rotating mechanical energy in the world, namely horizontal axis type and vertical axis type. The horizontal axis type adopts propeller blades, which face the wind direction and push the blades to rotate under the action of wind. This method has a relatively high utilization rate of wind energy, but this method must be equipped with a wind rudder so that the propeller blades face the incoming wind. When the wind direction is unstable, it will have a greater impact on the collection effect of wind energy. The most typical structural type of the vertical axis type is the three-cup anemometer, which uses the rotational driving force generated by the difference between the thrust of the concave surface facing the wind and the resistance of the convex surface...
