Streamline wind collection device

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.
