Abstract
The utility model relates to an automatic infrared telecontrol device for an air door, which is suitable for the automatic open and close of the air door of the downhole of a mine; the air door can be automatically opened in advance for 3-5 seconds when the personnel, vehicles, etc. pass the air door, and is automatically closed after the personnel or the vehicles pass the air door. The W [3] C [20] branch of a delay circuit of the utility model is connected in series with an anti-back discharge diode D [5], and the malfunction of the air door can be prevented when the electricity stops transferring. The automatic infrared telecontrol device for an air door is provided with a continuous discharge switch of the bicycles and pedestrians, and the continuous passing through the air door of vehicles and pedestrians can be ensured; the air door is not closed. The mutually latching of the wires of an alternating current contactor CJ [1], CJ [2] can be realized; the short circuit of the dynamic force power can be prevented when the control circuit generates malfunction.
Description
The utility model relates to a kind of infrared remote controller, particularly a kind ofly controls the device that the mine underground air door opens and closes automatically, and belongs to the mine ventilation field.
At present, the coal mine lower wind door overwhelming majority all is manual air door, and what some was called self closing door also all is the driving automatic door, promptly utilizes mine car direct collision formula.This so-called self closing door, also be hand push during the pedestrian or draw back air door, automaticity is extremely low, and application life is short, the spoilage height, maintenance load is big, so most of mine is still established the door trapper, even like this, also keeping away unavoidable air door is opened wide and is not related to or breaks the phenomenon of air door so that cause distinguished and admirable short circuit directly to jeopardize the ventilation safety of mine.
The purpose of this utility model is a kind of self closing door of design, when vehicle or personnel need be by air doors, it can shift to an earlier date for 3～5 seconds air door is opened automatically, when vehicle or personnel are arranged continuously by air door, air door will continue to open, treat that air door is just closed automatically after car, the people's all-pass, and can be manually when having a power failure.
Solution of the present utility model is: the W of delay circuit
3, C
20The branch road string has anti-reverse discharge diode D
5, A.C. contactor CJ
1And CJ
2Wiring realize mutual locking.This device is provided with special explosion-resistant enclosure.Position during the air door contract fully is provided with location switch DK
1Position when air door is opened entirely is provided with limit switch GK
1
Because underground air door adopts this device, so vehicle and pedestrian can accurately opening and closing by air door.Owing to adopted continuous delay circuit, accomplished not close by vehicle and personnel's air door continuously.After treating that car, people's all-pass are crossed air door, the ability self-closing damper.When having a power failure or certain fault occurring, can be manually opened or close air door.
