Abstract
The utility model provides an air curtain system for a mining movable hard refuge compartment, and aims to solve the problem that as the miners who survives the disaster opens the door of the refuge compartment to enter, toxic gases follow with the miners into the compartment, which are fatal to the miners. The key point of the air curtain system is that an outlet of a high pressure air cylinder, a pressure relief valve, a mechanical valve and a device forming the air curtain are sequentially connected through a pipeline; the device forming the air curtain is a rectangle formed by an air pipe and fixed on a door frame of an explosion-proof compartment door; a plurality of air outlets are uniformly arranged on the wall of the air pipe and face to the explosion-proof compartment door; and one end of a connecting rod is hinged with an air valve switch, while the other end of the connecting rod is hinged with the explosion-proof compartment door. The air curtain system for the mining movable hard refuge compartment is used for isolating the flow of the gases inside and outside the compartment door.
Description
Technical field
The utility model relates to and a kind ofly can discharge air and make the air of release form the system of curtain wall, is on being applied in around the doorframe of mining packaged type hardware survival capsule specifically, the air curtain system of the inside and outside gas flow of isolated hatch door.
Background technology
At present, mining packaged type hardware survival capsule is provided with the down-hole.When mine disaster took place, whole tunnel may be full of poisonous, flammable explosive gas.When wrecked personnel opened the lifesaving hatch door and enter in the cabin, toxic gas can enter in the cabin along with the hatch door of holding, and jeopardizes the life of personnel in the cabin.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of air curtain system of mining packaged type hardware survival capsule, and it can completely cut off toxic and harmful out of my cabin.
The purpose of this utility model is achieved in that the device of high pressure air bottle outlet, reducing valve, mechanical air valve, formation air curtain connects successively by pipeline; The device that forms air curtain is that tracheae surrounds rectangle, is fixed on the doorframe of explosion-proof hatch door, and several gas outlets evenly are set on tracheal wall, and open towards explosion-proof hatch door mouth all gas outlets; One end and the air valve switch of connecting rod are hinged, and the other end of connecting rod is hinged on the explosion-proof hatch door, and air valve is for opening state when explosion-proof hatch door is opened, and air valve is an off status when explosion-proof hatch door closes.After explosion proof door is drawn back, the connecting rod drive air valve that is connected on the explosion-proof hatch door is opened, by the device of reducing valve and formation air curtain, the gas with certain pressure sprays to the doorway from all gas outlets on the tracheae that surrounds rectangle air in the high pressure air bottle, forms air curtain successively.
Compared with prior art, the beneficial effects of the utility model are: it is simple in structure, is convenient to make, and saves cost; Secondly its residual high pressure air can also be the personnel's oxygen supply of taking refuge in the survival capsule in case of necessity as a kind of oxygen supply source.
Description of drawings
Further specify the utility model below in conjunction with accompanying drawing.
Accompanying drawing is a schematic diagram of the present utility model.
The specific embodiment
The device 5 of high pressure air bottle 1 outlet, reducing valve 2, mechanical air valve 7, formation air curtain connects successively by pipeline 3; The device that forms air curtain is that tracheae surrounds rectangle, is fixed on the doorframe of explosion-proof hatch door 6, and several gas outlets evenly are set on tracheal wall, and open towards explosion-proof hatch door mouth all gas outlets.The tracheae that surrounds rectangle can be one or more layers, and when one deck was above, tracheae was to form the number of plies on the direction perpendicular to the accompanying drawing paper; One end and the air valve switch of connecting rod 4 are hinged, and the other end of connecting rod is hinged on the explosion-proof hatch door, and air valve is for opening state when explosion-proof hatch door is opened, and air valve is an off status when explosion-proof hatch door closes.After explosion proof door is drawn back, the connecting rod that is connected on the explosion-proof hatch door is opened air valve, by the device of reducing valve and formation air curtain, the gas with certain pressure sprays to the doorway from all gas outlets on the tracheae that surrounds rectangle air in the high pressure air bottle, forms air curtain successively.
Claims (2)
1. the air curtain system of a mining packaged type hardware survival capsule is characterized in that: high pressure air bottle outlet, reducing valve, mechanical air valve, the device that forms air curtain connect successively by pipeline; The device that forms air curtain is that tracheae surrounds rectangle, is fixed on the doorframe of explosion-proof hatch door, and several gas outlets evenly are set on tracheal wall, and open towards explosion-proof hatch door mouth all gas outlets; One end and the air valve switch of connecting rod are hinged, and the other end of connecting rod is hinged on the explosion-proof hatch door, and air valve is for opening state when explosion-proof hatch door is opened, and air valve is an off status when explosion-proof hatch door closes.
2. according to the air curtain system of the described mining packaged type hardware survival capsule of claim 1, it is characterized in that: the tracheae that surrounds rectangle is one or more layers, and when one deck was above, tracheae was to form the number of plies on the direction perpendicular to the accompanying drawing paper.
