Said air-intake device comprises blast pipe and is installed on and is used to impel air inlet to rotate on the blast pipe air inlet to guarantee the first wind-guiding appearance that air inlet facings the wind.
Saidly go out wind apparatus and comprise discharge pipe and be installed on and be used to impel air inlet to rotate on the discharge pipe air outlet to guarantee the second leeward wind-guiding appearance of air inlet.
The air inlet of said blast pipe and the air outlet of discharge pipe are horn-like.
Said blower fan comprises that blower fan reaches the operating circuit for the blower fan power supply.
Said air inlet and air outlet are positioned at the diverse location of two apart from each others of said ventilation unit installation site, so that reach ventilation effect preferably.
When no natural wind, said blast switch device makes said blower fan work; When natural wind was arranged, air got into from said air-intake device, and said blast switch device is closed said blower fan, and the air after being circulated throughout goes out wind apparatus row from said again.
The utlity model has following advantage: (1) cost of manufacture is lower, and ventilated energy-saving is respond well; (2) working method does not need human intervention very flexibly; (3) through utilizing natural wind, cut down the consumption of energy very energy-conserving and environment-protective greatly; (4) applied range not only can be applicable to basement, can also be applied in the environment such as tunnel, and it is extensive to be suitable for prospect.
Figure of description
Accompanying drawing 1 is the overall structure figure of the utility model.
The specific embodiment
In order to make those skilled in the art can cross the content of understanding the utility model better, the utility model is done further elaboration below in conjunction with accompanying drawing.
This ventilation unit is provided with air-intake device, goes out wind apparatus, blast switch device, blower fan;
Air-intake device, go out the top that wind apparatus is installed in this ventilation unit installation site, blower fan is installed in the bottom of this ventilation unit installation site;
The blast switch device is installed on the air-intake device, and is electrically connected to blower fan, the work of control blower fan;
Air-intake device comprises blast pipe and is installed on and is used to impel air inlet to rotate on the blast pipe air inlet to guarantee the first wind-guiding appearance that air inlet facings the wind.
Going out wind apparatus comprises discharge pipe and is installed on and be used to impel air inlet rotate to guarantee the second leeward wind-guiding appearance of air inlet on the discharge pipe air outlet.
The air inlet of blast pipe and the air outlet of discharge pipe are horn-like.
Blower fan comprises that blower fan reaches the operating circuit for the blower fan power supply.
The blast switch device comprise a U type as blast pipe branch road air intake bend pipe that is connected in blast pipe and the normally closed blast contact switch that is connected to above-mentioned operating circuit.
Metal spring and sheet metal that normally closed blast contact switch comprises stay cord, stressed piston and is connected in operating circuit as blower fan work contactor; Metal spring one end is fixed in the air intake tube wall; A wherein end in contact of the other end and said sheet metal; The other end of sheet metal is fixed in the air intake tube wall, and two end points that metal spring and sheet metal are fixed in tube wall are connected into said operating circuit as the two ends of switch respectively, and stay cord one end is connected on the metal spring; The other end connects stressed piston, and stressed piston places the blast pipe body.
Said air inlet and air outlet are positioned at the diverse location of two apart from each others of said ventilation unit installation site, so that reach ventilation effect preferably.
As shown in Figure 1, this ventilation unit is provided with the first wind-guiding appearance 1, the second wind-guiding appearance 2, air inlet 3, air outlet 4, blast pipe 5, discharge pipe 6, air intake bend pipe, normally closed blast contact switch 8, fan wind inleting tube 9 blower fan 10 and operating circuits thereof;
