Description

Multifunctional life-saving fire-extinguishing device for high building

Technical Field

The invention relates to the field of fire-fighting, fire-extinguishing and life-saving, in particular to a multifunctional high-rise life-saving and fire-extinguishing device.

Background

In recent years, high-rise building fire casualties become a social problem, because of the high building, people evacuation and fire suppression are very difficult, the serious consequences of crowd death and crowd injury are often caused, huge losses are brought to the country and lives and properties of people, and at present, the limiting factors of high-rise building fire suppression are mainly concentrated on three major aspects: firstly, the lifting height of a lifting vehicle is limited, the existing best fire fighting lifting vehicle can only reach the height within 100 meters, and for trapped people on floors higher than the limit height, firefighters cannot utilize the lifting vehicle to rescue, and the effect of using a water gun or a water cannon to attack jet flow outwards can be greatly reduced, so that for higher floors, no reason can be given for the fire fighting lifting vehicle; secondly, the ability of the firemen to ascend is limited, the firemen at least climb up 20 kg of equipment, a large amount of physical power is consumed, and the fighting capacity is reduced due to the fact that the physical power is overdrawn after the firemen reach a fire layer; and thirdly, the limit of the ascending path is that when the power supply of the fire elevator is turned off and the elevating vehicle cannot reach the height of a fire layer, a fireman can only select to ascend along the internal evacuation stairs upwards, and at the moment, the fireman is influenced by the smoke-proof performance of the evacuation stairs, and can collide with the crowd evacuated downwards, so that the evacuation speed of the crowd is influenced, and the climbing speed of the fireman is prevented from being delayed.

Existing fire fighting equipment and techniques: firstly, the aerial ladder vehicle is used for fighting fire, the hidden danger is poor in stability, for example, after the working bucket reaches a certain height, the swing amplitude can reach two meters or three meters, under the condition, a fireman needs to control a water cannon to extinguish the fire, and needs to rescue people into the working bucket by means of a platform capable of extending out, so that the danger is great; the escape slideway mainly has two types, one type is a movable type, namely a product matched with the fire-fighting aerial ladder vehicle, is mainly suitable for being mounted on a holder of a climbing vehicle to rescue high-altitude trapped people, and is an auxiliary rescue mode for aerial rescue of the aerial ladder vehicle; the other type is fixed type, is suitable for people in high-rise buildings to quickly escape, and is generally fixed outside or inside the high-rise buildings (a safety channel is reserved); thirdly, the fire extinguishing bomb for the high building adopts a plurality of advanced technologies such as infrared laser composite detection, fire extinguishing bomb delivery, missile launching control and the like, the fire extinguishing bomb loaded with the high-efficiency dry powder extinguishing agent is delivered to a specified place quickly, accurately, safely and reliably, and the fire extinguishing bomb has the characteristics of no fire, no flame, no smoke, low noise and the like, and has the problem that the fire extinguishing bomb launched by the fire extinguishing bomb can break a window and enter the interior of the high building to spray the high-efficiency extinguishing agent for extinguishing fire only under the condition that personnel in the building with fire evacuate; fourthly, the household life-saving descent control device and the life-saving parachute are difficult to popularize at home, and people of all ages and both sexes need to learn to use and operate; fifthly, the plane eliminates the fire of the high-rise building, but in fact, the water quantity which can be carried by the plane is limited, and the plane is usually a water salary for the big fire of the high-rise building with complex situation; the escape compartment is arranged on a roof platform (or a refuge floor) of a high-rise building, the building structure is not damaged when the escape compartment is installed and used, the overall appearance of the building is not affected, when emergency conditions such as fire occur, a moving-out system of the escape compartment moves the moving platform out of the building body, trapped people can take A, B escape compartments in the equipment to slowly descend and escape to the ground, other preset floors can be subjected to rescue of the escape compartment, and if each building unit is provided with the escape compartment, the investment is too large; seventhly, a combined lifting device has the defects that guide rails must be installed on the outer wall of a high-rise building in advance, the cost of the guide rails of each 20-storey building is about 3 thousands of units, and the fire fighting equipment has the problems of single function, high operation difficulty, low lifesaving and fire extinguishing efficiency, high cost, difficulty in popularization and the like.
