Abstract
The utility model discloses a cofferdam in an escape capsule, wherein the interior of the escape capsule is separated into a main capsule and at least one cofferdam; the cofferdam is arranged between a main capsule door and the main capsule and provided with a cofferdam door. In the utility model, as the cofferdam is arranged between the main capsule door and the main capsule, the external toxic gas or permeable water can not enter the capsule, thus being capable of preventing secondary damage.
Description
Technical field
The utility model relates to the setting in a kind of survival capsule, relates in particular to the cofferdam that is provided with in a kind of survival capsule.
Background technology
Survival capsule provides the place of taking refuge to people when disaster takes place, be generally the cabin body with certain intensity.If but survival capsule is only established a cabin body, then can cause the poorly sealed and extraneous poison gas of main hatch door to enter in the cabin easily during greater than pressure out of my cabin when the cabin internal pressure, perhaps personnel pass in and out survival capsule under the permeable environment of mine laneway, water out of my cabin is easy to enter even fill in the cabin, thereby brings the possibility of secondary harm for the refugee in the cabin.
The utility model content
The purpose of this utility model is to provide the cofferdam in a kind of survival capsule, to overcome the defective that exists in the known technology.
For achieving the above object, the cofferdam in the survival capsule that the utility model provides is to be isolated into main cabin and at least one cofferdam in the survival capsule, and cofferdam is arranged between the main hatch door and main cabin of survival capsule, and cofferdam is provided with the isolation hatch door.
Cofferdam in the described survival capsule, wherein the main hatch door of survival capsule is to open to the outside of survival capsule.
Cofferdam in the described survival capsule, wherein isolating hatch door is to open to the inboard of survival capsule.
Cofferdam in the described survival capsule, wherein main hatch door and isolation hatch door are provided with weather strip, or are provided with weather strip with main hatch door and the corresponding doorframe of isolation hatch door.
Cofferdam in the described survival capsule is equipped with the rotational lock handle on wherein main hatch door and the isolation hatch door.
The cofferdam that the utility model provides makes extraneous toxic gas or permeable can't entering in the cabin between main hatch door and main cabin, thereby can prevent secondary harm.
Description of drawings
Fig. 1 is the generalized section of the utility model survival capsule, has shown main cabin and cofferdam in the survival capsule;
Fig. 2 is another angle schematic diagram of Fig. 1;
The specific embodiment
Please in conjunction with illustrated in figures 1 and 2, Fig. 1 and Fig. 2 have shown structure of the present utility model from different perspectives.Survival capsule of the present utility model cabin body is to adopt the steel plate calendering formation can bear powerful vibrations, impact force and pressure that general accident of mine disaster produces, weld reinforcing rib then as one section, again with the closed structure of the band door that couples together with bolt and sealing ring between each section.Be isolated into main cabin 10 and at least one cofferdam 11 in survival capsule 1, cofferdam 11 is between main hatch door 12 and main cabin 10.And main hatch door 12 is designed to outwards (cabin is external) unlatching, isolates inwardly (in the body of cabin) unlatching of hatch door 13.Rotating handles 14 was tight with main hatch door and cofferdam door lock after personnel entered in the survival capsule, and the handle of installing on main hatch door of the present utility model and the isolation hatch door is the handle of known rotational lock.
The utility model is to consider that the cabin internal pressure is greater than pressure out of my cabin.When being provided with cofferdam, the cabin internal pressure acts on to isolate on the hatch door 13 it is sealed more, even extraneous pernicious gas enters under the situation that main hatch door is not closed completely and also isolated hatch door in the main hatch door and be blocked in cofferdam and can not enter in the survival capsule.Equally, when mine was permeable, extraneous hydraulic action sealed it on main hatch door more.Therefore increase cofferdam and can play the effect that inside and outside hatch door seals more.If have the people to enter the cabin simultaneously, also just pour into a part of water in the cofferdam, the safety in the main cabin is out of question.And the pollution that also can reduce in the cofferdam air ambient in the cabin is set.
On main hatch door of the present utility model and isolation hatch door, a circle weather strip can also be set, perhaps on the doorframe of main hatch door and isolation hatch door correspondence, a circle weather strip be set with increase sealing effectiveness (the sealing strip material is a known technology).
Need to prove that survival capsule of the present utility model can be isolated into several cofferdams as required, the structure of each cofferdam is all identical, and specific embodiment of the utility model and accompanying drawing are only enumerated a cofferdam and described.
Claims (6)
