Abstract
The invention provides a wind door for positive wind and opposite wind of a mine. A positive wind door and an opposite wind door are connected into a whole through a connecting board and are arranged on a special door frame. When having the positive wind, the positive wind door is closely closed under the pressure of the positive wind; and when having the opposite wind, the opposite wind pushes the positive wind door to be closed and drives the opposite wind door to be automatically closed. When recovering the positive wind, the positive wind pushes the opposite wind door to be opened and closes the positive wind door. With the force of the wind flow and the wind pressure of the mine, the wind door can be switched between the positive wind door and the opposite wind door, thereby achieving the aim that the direction of the wind flow has to be changed within 10min specified by coal mine safety regulation.
Description
Affiliated technical field
Automatic wind door for positive wind and opposite wind of mine relates to a kind of air door of controlling mine ventilation, belongs to the mine ventilation structure.
Technical background
The mine ventilation air door adopts horizontal sliding twice air door at present.The per pass air door also must be equipped with reverse throttle except that joining the forward air door, use during in order to the disaster inverted ventilation.When the generation disaster needed inverted ventilation, mine tens road air doors must manually remove to switch the inverted ventilation door.Taking place under the situation of disaster, changing the wind direction in the tunnel in 10 minutes that manual switching does not realize not only that " safety regulations in coal mine " require, and entering the disaster district, to remove to switch air door also be unsafe.Even so main ventilating fan can be in 10 minutes the anti-wind of crossing, underground air door can not in time switch, and must cause down-hole ventilation system confusion, can not realize safe inverted ventilation.
Summary of the invention
Solution of the present invention is: the righteous style and practice air door of automatic wind door for positive wind and opposite wind of mine and door for air reversing are assembled into integral body with junction plate by the angle greater than 90 degree.Axis hole in order to the air door rotation is arranged, in order to insert on the axis of rotation on the doorframe on the junction plate.During righteous style and practice, the righteous style and practice air door under positive wind pressure by tight closing; During inverted ventilation, the distinguished and admirable righteous style and practice air door of pushing open of inverted ventilation promotes door for air reversing simultaneously and closes automatically.When recovering righteous style and practice, same, righteous style and practice is distinguished and admirable can be pushed door for air reversing open again, and the righteous style and practice air door is closed.This air door structure is simple, and ventilation system is safe and reliable in the time of can guaranteeing righteous style and practice and inverted ventilation, no matter the righteous style and practice inverted ventilation can both be closed automatically.Simultaneously, the flexible square tube of caulking gum is housed in air door doorframe periphery inboard, the flexible square tube of door-plate compression seal rubber when air door is closed, square tube can be stretched, and can realize that air door is close to doorframe, reduces air door and leaks out.
Beneficial effect
The present invention has following advantage:
1, simple in structure, close tight, reduce leak out, dependable performance.
2, realized closing automatically, avoided the manual switching air door, guaranteed the requirement of 10 minutes realization inverted ventilation.
3, close, switch only by the wind direction blast, without other power.
Do following detailed description the in detail below in conjunction with accompanying drawing and specific implementation method

Concrete implementation example
Illustrated automatic wind door for positive wind and opposite wind of mine, righteous style and practice air door (1) mutually is interconnected into integral body with upper junction plate (3) with lower connecting plate (4) by the angle greater than 90 degree with door for air reversing (2), upper shaft hole (5) and lower shaft hole (6) are arranged respectively on upper junction plate (3) and the lower connecting plate (4), insert respectively in the doorframe upper ledge axis of rotation (8) and lower frame axis of rotation (9) of doorframe (7).Because righteous style and practice air door (1) door for air reversing (2) can cover air door doorframe (4) completely, during righteous style and practice, under the promotion of just distinguished and admirable (5), righteous style and practice air door (1) is closed, and door for air reversing (2) is opened under the drive of righteous style and practice air door (1).During inverted ventilation, inverted ventilation distinguished and admirable (6) drum is opened righteous style and practice air door (1), promotes door for air reversing (2) simultaneously and closes.The flexible square tube (11) of caulking gum is housed in the peripheral inboard of air door doorframe (7), the flexible square tube (11) of door-plate compression seal rubber when air door is closed, square tube can be stretched, and can realize that air door is close to doorframe, reduces air door and leaks out.
Claims (1)
1. automatic wind door for positive wind and opposite wind of mine, it is characterized in that: righteous style and practice air door (1) mutually is interconnected into integral body with upper junction plate (3) with lower connecting plate (4) by the angle greater than 90 degree with door for air reversing (2), upper shaft hole (5) and lower shaft hole (6) are arranged respectively on upper junction plate (3) and the lower connecting plate (4), insert respectively in the doorframe upper ledge axis of rotation (8) and lower frame axis of rotation (9) of doorframe (7), the flexible square tube (11) of caulking gum is housed in the peripheral inboard of air door doorframe (7), make air door be close to doorframe, reduce air door and leak out.
