When there is no wind, the standby solar suction fan is activated, and the gas in the indoor air stagnation area can also be sucked out through the standby exhaust pipe. In this way, the shortcomings of the prior art are avoided.

Technical solution of the present invention:

An energy-saving ventilation device for indoor air stagnation areas, characterized in that it includes an air inlet, adjustable blades, a rotating shaft, a blade opening adjustment valve, a contraction section, an air inlet channel direction positioning mechanism, and an exhaust mechanism; the adjustable The blade is connected to one end of the contraction section through the rotating shaft, and the blade opening adjustment valve is connected with the rotating shaft through a connecting line to adjust the opening of the adjustable blade; the air inlet channel direction positioning mechanism includes a wind vane, a vertical shaft, wind direction positioning pointer and positioning valve, the upper end of the vertical shaft is connected with the wind vane, and the lower end of the vertical shaft is connected with the wind direction positioning pointer; Located in the constriction section on the upper part of the standpipe, the diffuser section of the air outlet is connected to the other end of the constriction section; a sleeve is arranged under the constriction section, and the positioning valve is arranged on the sleeve for Adjust the angle of rotation of the shrinkage section on the standpipe.

A spare exhaust pipe is also arranged in the air outlet, the rear end of the spare exhaust pipe is placed at the front of the spare solar suction fan, and the spare solar suction fan is placed at the rear of the diffusion section of the air outlet.

The constricted section has an enlarged section at both ends and a throat with a gradual cross-section in the middle, and the air outlet is located below the position of the throat with a gradual change.

The structure of the device of the present invention is composed of two parts: an air inlet channel mechanism and an air exhaust channel mechanism. In the mechanism part of the air inlet, there are air inlets, adjustable blades, blade opening adjustment valves, wind vanes and positioning valves. The valve adjusts the opening of the adjustable blades to ensure that the air flow at the air inlet is at an optimal value. In the mechanism part of the exhaust duct, set the constriction section, the air exhaust port, the diffuser section of the air outlet, the spare exhaust pipe and the spare solar suction fan. , so that the air pressure in the indoor air stagnation area is higher than the air pressure in the contraction section, so that the gas in the indoor air stagnation area flows to the diffuser section of the air outlet; when there is no wind, the spare solar suction fan is activated, and the indoor air stagnation area can also be discharged through the spare exhaust pipe. Air is sucked out. Advantages of the present invention: Compared with the prior art, the present invention utilizes its own structure to realize natural ventilation, significantly saves electricity, has a better discharge effect of indoor trapped air, lower use cost, is suitable for ventilation of indoor air stagnant areas, and has a large space for promotion larger.

detailed description

Referring to accompanying drawing 1, air inlet 1, adjustable blade 2, rotating shaft 5, upper part of connection line 6, air outlet 7, contraction section 8, wind vane 9, upper part of vertical shaft 10, diffuser section 13 of air outlet, spare exhaust pipe 14 and the spare solar suction fan 15 are placed on the roof 16; the casing 3 and the vertical pipe 17 are located below the contraction section 8; the lower part of the casing 3, the blade opening adjustment valve 4, the lower part of the connecting line 6, the wind direction positioning pointer 11, and the positioning valve 12 and the lower part of the vertical pipe 17 are placed indoors; the adjustable blade 2 is rotationally connected with the rotating shaft 5, the blade opening regulating valve 4 is fixed at the lower end of the vertical pipe 17, the blade opening regulating valve 4 is connected with the rotating shaft 5 through the connecting line 6, and the wind vane 9 Located at the top of the vertical shaft 10, the wind direction positioning pointer 11 is located at the bottom of the vertical shaft 10, the positioning valve 12 is arranged on the bottom side wall of the casing 3, and the positioning valve 12 is in snap contact with the vertical pipe 17.

Working process: When there is wind, the wind vane 9 rotates and transmits it to the wind direction positioning pointer 11 through the vertical axis 10. According to the wind direction displayed by the wind direction positioning pointer 11, the vertical pipe 17 is rotated to drive the upper structure to rotate. The valve 12 is positioned so that the direction of the air inlet 1 is consistent with the wind direction of the wind vane 9; through the blade opening adjustment valve 4, the connecting line 6 and the rotating shaft 5 at the bottom of the standpipe 17, the adjustable blade 2 is adjusted to adjust the air flow rate of the air inlet 1. Adjust to the best; when there is a breeze, adjust the opening of the adjustable blade 2 to collect more wind energy, so that the wind speed at the contraction section 8 is fast enough, the kinetic energy increases, and the corresponding pressure energy decreases. When the contraction section 8 When the wind pressure is lower than the air pressure in the indoor air stagnation area, the gas in the indoor air stagnation area is discharged to the air outlet diffusion section 13 through the air outlet 7; The air duct 14 can also suck out the gas in the indoor air stagnation area to complete the discharge of the gas in the indoor air stagnation area.
