Description

Refuge device for emergency life support

Technical Field

The utility model relates to a safety protection field, concretely relates to device of taking refuge of emergent life support of proruption.

Background

With the rapid development of economy and the improvement of life quality of people, buildings are forced to develop into high-rise and multi-storey basements, once a fire disaster happens, the escape direction can not be found immediately and the building leaves the scene often due to the diffusion of high temperature and dense smoke in a fire scene, and the situation can not be imagined later. At present, the known fire-fighting facilities mainly comprise the following: first, fire extinguishing (extinguisher); secondly, alarming (fire detector, alarm); thirdly, fire hydrants; fourthly, an automatic water spraying system and the like. The above facilities play a certain role in the aspect of fire fighting. However, after a fire occurs, the fire is large or the fire spreads quickly, and under the condition that personnel or materials on the fire scene cannot escape or evacuate from the fire scene in time, most of the facilities have no obvious or even no function. For the situation that the fire and smoke are too fast suddenly, self rescue is difficult, and the situation that 'the fire cannot go out and the smoke cannot go in' is easily caused, great difficulty is also caused for the rescue of the fire department. Only when the fire disappears or the fire extinguishes, the fire fighters can enter the fire fighting equipment, but when the fire fighters enter the fire fighting equipment, the fire fighters die and the objects are burnt, so that the tragedy of family damage and death is usually caused, and the loss is very large.

After a fire disaster occurs, the fire is large or the fire spreads fast, people or materials on the fire scene cannot escape or evacuate from the fire scene in time, smoke is dense, external rescue personnel cannot arrive or approach in time, the fire cannot go out of the fire scene, the existing refuge device cannot move, the fire can only wait in situ for being diminished or being extinguished, the trapped people can be greatly psychologically obstructed, and in case of the fire disaster, explosion or collapse and the like can possibly bring harm to the trapped people.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the problem that the traditional refuge device can not move.

In order to achieve the purpose, the basic scheme of the utility model provides a refuge device for emergency life support, which comprises a shell, a refuge cavity, a power mechanism arranged at one end of the lower part of the shell and a steering mechanism arranged at the other end of the lower part of the shell, wherein a heat insulation layer is arranged between the power mechanism and the refuge cavity, and a heat insulation layer is arranged between the steering mechanism and the refuge cavity;

The principle and effect of this basic scheme lie in:

1. the principle of a steam engine is adopted, when a fire disaster happens, people hide in a refuge bin, water in a water storage tank is heated at high temperature of the fire disaster to generate steam, the steam enters a cylinder through a slide valve chamber, a piston is pushed to move inwards, the piston pushes air on the inner side to move upwards, a slide valve moves forwards to plug a channel, the channel where the steam enters is changed, the steam enters the cylinder from the other side again, the piston is pushed to move outwards, and a crank is driven to move through the left-right movement of the piston, so that a power wheel is driven to start to move. The device can be moved by utilizing the existing conditions without adding an additional power source, so that the cost is reduced.

2. When the power wheel moves, the driven wheel and the universal wheels move along with the power wheel, the steering mechanism controls the two front universal wheels, when the steering wheel is rotated, the rotating rod rotates along with the power wheel, the driving bevel gear at the lower end of the rotating rod also rotates along with the rotating rod, the driven bevel gear meshed with the driving bevel gear rotates to drive the gear coaxially connected with the driving bevel gear to rotate, and the gear drives the rack to move leftwards or rightwards, so that the moving direction of the universal wheels is changed, and the moving direction of the whole device can be changed.

3. The outside environment can be seen from the observation window on the sealing door when the trapped person controls the direction to be moved, and the escape route can be recognized.

4. The casing includes flame retardant coating, thermal insulation layer, resistance to compression inlayer, resistance to compression skin and sealing door, and the life can obtain furthest's guarantee when stranded personnel hide in the device, can not suffer the injury of high temperature and explosion.

5. Compared with the prior art, the device can remove, and when the intensity of a fire was too big, stranded personnel can't escape, rescue personnel also can't get into, the device just can play a role, and stranded personnel can select control device to reach the escape door that has not been fired yet, perhaps the window that rescue personnel conveniently rescued, and the scene of a fire that leaves is faster can prevent other unexpected condition from appearing when waiting in situ.

Furthermore, the flame retardant coating is coated on the resistance to compression skin, and the internal surface of resistance to compression inlayer uses fire-resistant software material, and the equipartition has damping spring between resistance to compression inlayer and the resistance to compression skin. The trapped people who are sheltered in the device can be better protected from high temperature, explosion or falling objects.

Furthermore, fire extinguishing equipment is arranged in the refuge cavity. When the fire is not great or reduced, the trapped people can use the fire extinguishing equipment to extinguish the fire by themselves to ensure the life safety after confirming the safety of the surrounding environment.

Further, a rattle is arranged on the shell. The rescue positioning device is used for asking for help, and can quickly find the position of a trapped person when a rescuer enters a house to help the person.

Further, a compass is arranged in the refuge cavity. When the trapped person with excessive fire cannot observe the external environment from the observation window but wants to leave the scene, the compass can be used for distinguishing the movement of the direction control device.

Furthermore, the observation window adopts fire-proof, high temperature resistant and explosion-proof double-layer glass. The trapped person can safely observe the external environment in the device, and can accurately find the escape route when moving.

Further, the housing height is less than the height of the home door, and the housing width is less than the width of the home door. The device can be removed from the room to a more convenient or safe location for escape.
