[0002] Mine air window is also called regulation air window, and is an important component in a mine ventilation system, mainly used for cutting off air flow, and creating conditions for on-demand distribution of mine air flow. By reasonably setting the regulation air window, the air volume of different areas inside the mine can be effectively controlled to ensure that each working face obtains the required air volume, thereby maintaining the ventilation balance inside the mine. The regulation air window not only has the function of cutting off air flow, but also provides convenience for pedestrians and transportation in the mine; under the premise of not affecting the ventilation effect, the regulation air window also enables the staff and equipment to pass through conveniently.

[0003] The mine air window anti-backflow device is a safety protection device specially used in a coal mine, and its main function is to prevent gas backflow in the air cylinder of the air supply system when a mine outburst occurs, thereby improving the safety of the mine ventilation system. The mine outburst usually refers to the coal and gas outburst occurring during the mining process in the coal mine; it is a serious geological disaster, and specifically refers to the sudden emission of a large amount of coal and gas from the coal and rock mass under the action of coal and ground stress, and is therefore also commonly referred to as "coal and gas outburst".

[0007] The utility model discloses a working principle lies in: when the mine is in the outburst accident, owing to the wind flow counter current, the spacing plate is slipped on the bolt through the strip-shaped through -hole, and simultaneously drives the window sash to move, makes the sealing washer close to the window frame, when the window sash and the wedge -shaped block contact spring is driven, and then under the action of spring, drives the wedge -shaped block reset, and the window sash can be closed.

[0008] The utility model discloses the beneficial effect lies in: the utility model discloses a spacing plate drive window sash sliding mode for realizing the effect that the window sash can be closed in time when the outburst accident occurs, and this design is not only simple structure convenient operation, can effectively block the wind flow and prevent the wind flow reverse, reduce the disaster area, enhance the mine disaster -resistant capacity.

[0009] Scheme two, this is the preferred basis scheme, one side on the window frame is equipped with the sliding slot, the louver is slidably connected on the sliding slot, the sliding block is fixedly connected on the louver, and the sliding block is slidably connected in the sliding slot.

[0010] Scheme three, this is the preferred basis scheme, the window frame on the one side of hinged window sash is equipped with self -locking mechanism, the self -locking mechanism includes the mounting plate, the spring is fixedly connected on the mounting plate, and the wedge -shaped block is fixedly connected on the other end of spring.

[0011] Scheme four, this is the preferred basis scheme, the sealing washer is equipped on the one side of window sash and window frame contact.

[0012] Scheme five, this is the preferred basis scheme, the other side of window sash is equipped with the reinforcing rod. DRAWINGS
