Based on the neck bundle effect, the air inlet is a positive pressure area, the air outlet is a negative pressure area, a speed-increasing fluid channel is formed in the air collecting pipe 1, and the air speed is increased after the air passes through the air collecting pipe bundle.

The air outlet is connected with one end of the air guide cover 3, a wind collecting tube bundle and the air guide cover 3 are welded, the air outlets of the adjacent wind collecting pipes 1 are connected through connecting plates 14, a plurality of wind guide cones 13 are arranged in the air guide cover 3, the axes of the wind guide cones 13 are parallel to the axes of the wind collecting pipes 1, the wind guide cones 13 comprise cones, the bottoms of the cones are connected with wind guide parts, and the outer side faces of the wind guide parts are parallel to the axes of the wind collecting pipes 1.
