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 streamlined wind collection device, which is characterized in that it comprises: a hub; support rods, M support rods are radially evenly distributed on the outer circumference of the hub; wind buckets are arranged on each support rod from outside to inside N wind buckets are provided to form N wind bucket groups, each wind bucket is a hollow, streamlined curved surface structure with a wind-facing opening in the circumferential direction of the hub, and the streamlined curved surface gradually shrinks from the wind-facing opening to a closed curved surface, wherein, M≥3, N≥1. The invention proposes a streamlined wind collection device, which replaces the wind cup with a composite streamlined wind bucket, which can reduce the resistance of wind force acting on the back of the wind bucket in all directions, increase the driving force of the device, and reduce the overall wind resistance, thereby improving the wind collection efficiency.

Description

technical field [0001] The invention relates to the field of wind energy utilization, in particular to a streamlined wind collecting 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...
