Abstract
A linking apparatus for air curtains of a cabin door is provided hereby. An exhaust duct is arranged at one side of the cabin door and the exhaust duct is provided with air outlets thereon; the exhaust duct is connected with a compressed air pipe through a ventilating duct; when the cabin door is closed, the cabin door presses the switch of the linking apparatus, which retains air in the exhaust duct. When the cabin door is opened, the switch of the linking apparatus is made open and the air blown out of the exhaust duct forms an air shield wall, which prevents poisonous air from entering the cabin but does not bother when rescue workers come in and go out of the cabin. Thereby, the linking apparatus for air curtain of the utility model can effectively prevent people in the cabin from being poisoned and at the same time does not cause inconvenience to people who enter and leave the cabin.
Description
Technical field
The utility model relates to a kind of hatch door air curtain linkage, relates to a kind of hatch door air curtain linkage that is used for survival capsule particularly.
Background technology
Survival capsule is to use under the situation of environment very abominable (such as mine disaster takes place) around, often produces a large amount of pernicious gases during mine generation disaster.Therefore enter when taking refuge in the survival capsule when people open hatch door, pernicious gas out of my cabin also just is brought in the cabin thereupon, can cause personnel's poisoning in the cabin.
The utility model content
The purpose of this utility model is to provide a kind of hatch door air curtain linkage, when opening hatch door pernicious gas is kept off outside hatch door.
For achieving the above object, the hatch door air curtain linkage that the utility model provides, primary structure is: a side that is positioned at hatch door is equipped with exhaust duct, offers vent on this exhaust duct, and exhaust duct is connected to pressure ventilation pipe by ventilation duct.
Described hatch door air curtain linkage, wherein pressure ventilation pipe is connected on the air accumulator that is provided with in the survival capsule.
Described hatch door air curtain linkage, wherein air accumulator is connected with the pressure air pipe of down-hole.
Described hatch door air curtain linkage wherein is equipped with the linked switch that this air curtain of control opens and closes on the hatch door.
Described hatch door air curtain linkage, wherein exhaust duct is installed in any side or the many sides (upside, downside, left side are or/and the right side) in the hatch door.
The hatch door air curtain linkage that the utility model provides, when hatch door was closed, hatch door was pushed down linked switch, and exhaust duct does not have air to discharge.When hatch door was opened, linked switch was opened, and the air that exhaust duct blows out forms the shroud of gas wall, stop pernicious gas out of my cabin to enter in the cabin, but not influence personnel pass in and out survival capsule, therefore can avoid personnel's poisoning in the cabin, can not influence the inside and outside personnel in cabin again and pass in and out survival capsule.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
See also shown in Figure 1, hatch door air curtain linkage of the present utility model, be in a side that is positioned at hatch door 1 exhaust duct 3 to be installed, exhaust duct of the present utility model can be installed in any side or the many sides in the hatch door 1, the schematic diagram that is mounted in a side that Fig. 1 provides.Offer vent on this exhaust duct 3, exhaust duct 3 is connected to pressure ventilation pipe 4 by ventilation duct 5, pressure ventilation pipe is connected to (air accumulator that the utility model adopts is a known technology, and the air accumulator of operating air pressure is provided to brakes such as the storage compressed air that uses on the automobile) on the air accumulator that is provided with in this survival capsule.Compressed air in this air accumulator is that the pressure air pipe by the down-hole provides.The linked switch 2 that this air curtain of control opens and closes is installed, by the unlatching of these linked switch 2 control pressure ventilation pipes 4 on hatch door 1.This linked switch 2 can be a known mechanically controlled valve, is serially connected between pressure ventilation pipe 4 and the ventilation duct 5.Linked switch 2 is unlocked when hatch door 1 is opened; pressure ventilation pipe 4 is ventilated and is entered exhaust duct 3 by ventilation duct 5, and the air that the steam vent on the exhaust duct 3 blows out makes one air curtain of whole hatch door interruption-forming, separating in the cabin Yu out of my cabin; prevent that pernicious gas out of my cabin from entering in the cabin, plays a protective role.When hatch door was closed, hatch door was pushed down linked switch 2, and exhaust duct 3 stops to blow.
In sum, when the utility model is opened when hatch door, the air curtain linked switch is opened, the shroud of gas wall of one outside blowing of hatch door interruption-forming this moment, stop pernicious gas out of my cabin to enter in the cabin, but not influence personnel pass in and out survival capsule, therefore can avoid personnel's poisoning in the cabin, can not influence the inside and outside personnel in cabin again and pass in and out survival capsule.
Claims (5)
