Specific embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, the detailed implementation method and specific operation process are given, but protection scope of the present invention is not limited to
Following embodiments.
Embodiment
As shown in Figure 1, a kind of non-maintaining power quality controlling device in open air, the electric energy matter including cabinet and in cabinet
Amount administers circuit and fan 10, and cabinet is equipped with thermovent 2, thermovent 2 and fan 10 two sides that be respectively arranged on cabinet opposite
On face, it is oppositely arranged the convection current that can increase air in cabinet；Power quality controlling circuit includes central controller 8 and connection center
The temperature sensor 9 of controller 8；The baffle 1 of openable closure thermovent 2 is equipped on the inside of thermovent 2, baffle 1 passes through driver
Structure connects motor 5, and motor 5 and fan 10 connect central controller 8.
Transmission mechanism includes the gear 6 and rack gear 7 to match, and gear 6 connects the output shaft of motor 5 and is set to 1 water of baffle
Square to side, rack gear 7 it is horizontal it is fixed is located at 1 inside of baffle, the downside of baffle 1 is equipped with the sliding rail 3 of groove-like, and baffle 1 exists
It is translated in groove.In the present embodiment, rack gear 7 and gear 6 are all straight-tooth, and motor 5 is stepper motor, and gear 6 is located at thermovent 2
It is greater than the length in the horizontal direction of baffle 1 at a distance from right side, with thermovent 2, guarantees that baffle 1 can fully open thermovent 2.Motor
5 are fixed on cabinet, drive the rotation of gear 6 to drive baffle 1 to right translation by output shaft.
In the present embodiment, it is designed with the smooth polytetrafluoroethylene ethylene layer in surface on the contact surface of baffle 1 and sliding rail 3, is dropping
While low gear 1 mobile frictional force of plate, avoid using the isostructural complexity of pulley.
