Abstract
The utility model discloses a coal mine movable life saving capsule with a heat insulation and thermal preservation structure, which comprises a transition capsule, a main capsule and an equipment capsule, wherein the heat insulation and thermal preservation structure is arranged in a gap between the outer wall and the inner wall of a capsule body and comprises a vacuum layer, a vitrified micro bubble layer is filled in the vacuum layer, and an air pumping device communicated with the vacuum layer is also arranged on the outer wall or the inner wall of the capsule body. A 50mm space is formed between the outer wall of the life saving capsule and the inner wall of the life saving capsule and carries out vacuum pumping. The air heat conduction is effectively prevented, the vitrified micro bubble layer is uniformly placed in the vacuum layer, and the introduction of the radiation heat outside the capsule is effectively solved. In order to maintain a high vacuum degree of the vacuum heat insulation layer and process air remained in the vacuum layer and air molecules subsequently generated by various materials, porous sintering type air absorption agents are placed in the vacuum sandwich layer. Therefore, the remained air in the sandwich layer is eliminated, and simultaneously, the vacuum degree can be maintained for a long time.
Description
Technical field
The utility model relates to a kind of mining disaster-resistant rescue capsule, is a kind of portable survival capsule in colliery with heat-insulation and heat-preservation structure specifically, belongs to mining lifesaving appliance technical field.
Background technology
The portable survival capsule in colliery is arranged on the confined space in each dangerous work zone under the mine, is generally the steel cavity, can accomplish airtightly in the global design, and can resist certain external impacts.Inside has air handling system, oxygen feed system, carbon monoxide (CO) and carbon dioxide (CO2) cleaning system, electric power system and communication system usually, and corresponding monitor, safeguard procedures, also have enough water and food simultaneously.After mine disaster takes place, the personnel that can't directly transfer to the safety zone can enter the survival capsule space, it is isolated to close hatch door and extraneous hostile environment, inner each life saving system of operation subsequently, temperature in the control cabinet produces oxygen, and handles pernicious gases such as CO, CO2, detect all kinds of ambient parameters in the confined space, environment in the space is maintained the suitable condition of human survival.Survival capsule will guarantee take refuge personnel existence of inside, just must guarantee in the cabin temperature in the regular hour, continually and steadily in certain temperature range, normally in the cabin average temperature less than 30 degrees centigrade.Might be in out of my cabin under the catastrophe state in the lasting hot environment, this situation can cause that temperature rises in the survival capsule, causes in the cabin personnel because of the too high appearance that various dangerous situations take place of temperature in the cabin.Though aircondition is installed in the survival capsule, owing to be subjected to environmental constraints not have enough big power to eliminate the intrusion of external heat source fully.Coefficient of thermal conductivity is made up of four parts; λ=λ solid conductive heat coefficient+λ gas conduction+λ radiation+λ convection current.And the coefficient of thermal conductivity of air accounts for 50% of the total coefficient of thermal conductivity of material, even higher.Reducing the air coefficient of thermal conductivity is an important step that reduces temperature intrusion out of my cabin.
China's utility model patent 201020245549.4 discloses a kind of escape capsule that is applied to emergency escape in mine or the deep water, the cabin body that comprises tubular, the cross section of described cabin body comprises rectangle or square outer ring and is inscribed within the oval or circular inner ring of described outer ring, the side of described cabin body is provided with hatch door, and the space between described outer ring and the inner ring is provided with the configuration storehouse.Above-mentioned utility model adopts asbestos material that the cabin body is incubated and is heat insulation, and its heat insulating effect is poor, for the infringement of long period pressure and high temperature, can not keep the scope that temperature suits the survivor in the cabin in rescue time.
The utility model content
Deficiency at the prior art existence, technical problem to be solved in the utility model is, a kind of heat insulation, high insulating effect is provided, effectively stop in the external heat source invasion cabin, guarantee the portable survival capsule in the continual and steady within a certain period of time colliery that has the heat-insulation and heat-preservation structure in certain temperature range of temperature in the cabin.
For solving the problems of the technologies described above; technical solution adopted in the utility model is: a kind of portable survival capsule in colliery that has the heat-insulation and heat-preservation structure; comprise transfer chamber, main cabin, equipment compartment; in the space between external wall in described cabin and the inwall heat-insulation and heat-preservation structure is set; described heat-insulation and heat-preservation structure comprises vacuum layer; in vacuum layer, fill the glass bead layer, on external wall in cabin or inwall, also be provided with the air extractor that is communicated with vacuum layer.
The portable survival capsule in the above-mentioned colliery that has the heat-insulation and heat-preservation structure, described air extractor comprises exhaust tube, connects vacuum meter on exhaust tube, and described exhaust tube one end connects vacuum layer, and the other end connects evacuating valve.
Above or below the portable survival capsule in the above-mentioned colliery that has the heat-insulation and heat-preservation structure, the glass bead layer in the described vacuum layer getter layer is set.
The portable survival capsule in the above-mentioned colliery that has the heat-insulation and heat-preservation structure, the thickness of described vacuum layer is set to 50mm.
The advantage that the utility model has the portable survival capsule in colliery of heat-insulation and heat-preservation structure is: the space of 50mm is arranged then to its extracting vacuum between the outer wall of survival capsule and survival capsule inwall.Stoped the heat conduction of air effectively.The coefficient of thermal conductivity of glass bead own is extremely low to have good heat-insulating property, evenly places the glass bead layer in vacuum layer, efficiently solves photothermal importing into out of my cabin.In order to make vacuum heat-insulating layer keep higher vacuum and to handle remaining gas in the vacuum layer, and the gas molecule of the follow-up generation of various materials, porous sintered type getter in vacuum interlayer, placed.So both eliminated the vacuum that residual air in the interlayer can guarantee the long period simultaneously.Simultaneously, the air extractor of setting can be bled to vacuum layer at any time, and gas clean-up prolongs temperature retention time.
