The working principle of the invention is as follows: the principle of air exhaust: the motor 5 is connected into a circuit, the motor 5 is started, and the motor 5 rotates to drive the motor bevel gear 5-1 to rotate. The left side of the motor bevel gear 5-1 is meshed with the right bevel gear 2-4, and the right bevel gear 2-4 rotates along with the motor bevel gear 5-1. The right bevel gear 2-4 is fixed at the right end of the horizontal shaft 2, and the horizontal shaft 2 rotates. The left bevel gear 2-1 is fixed to the left end of the horizontal shaft 2 so that the left bevel gear 2-1 rotates. The left bevel gear 2-1 is meshed with the vertical shaft bevel gear 9-6, and the vertical shaft bevel gear 9-6 rotates along with the left bevel gear 2-1. The vertical shaft bevel gear 9-6 is fixed in the middle of the vertical shaft 9, so the vertical shaft 9 rotates, and the impellers 9-2 are fixed at two ends of the vertical shaft 9, so the impellers 9-2 rotate. The air exhaust direction of the impeller 9-2 on the upper side of the vertical shaft 9 is upward; the air exhaust direction of the impeller 9-2 below the vertical shaft 9 is lower.

Principle of change of air outlet opening degree: the hydraulic cylinder 10 is connected to the hydraulic system. When oil is supplied to the left lower oil hole I10-3-3, oil enters the left side of the piston 10-2, and as the oil increases, the pressure on the left side of the piston 10-2 is about the pressure on the right side, and the piston 10-2 moves to the right. The hydraulic cylinder 10 is shortened, the piston rod 10-2-1 drives the lower air baffle 6-6 to rotate clockwise around the rotating pin, the opening of the air port is increased, and the air outlet quantity is increased; the upper hydraulic cylinder contracts to drive the air inlet baffle 6-1 to rotate anticlockwise, and the opening degree of the air inlet is reduced.

Wind and water filtration: the impeller 9-2 rotates to generate negative pressure on the right side of the air box 6, and fresh air enters the air box 6 from the rain baffle 4. The water content in the air is increased in rainy days, and a part of the air passing through the rain baffle 4 is blocked by the rain baffle 4 and stays on the rain baffle 4. The air continues to move to the left and, when it meets the screen 3, a part of the water is filtered out through the filtering stop of the screen 3.
