Description

technical field [0001] The invention belongs to the technical field of fire-fighting devices, and relates to a combined automatic stair-climbing fire-fighting and smoke-exhausting robot. Background technique [0002] Due to the continuous acceleration of the urbanization process, various entertainment venues, office buildings, super shopping malls, basements, high-rise buildings, etc. continue to appear, coupled with the further improvement of urban infrastructure, the subway has gradually become the main transportation facility in large and medium-sized cities, and various The continuous construction of large petrochemical plants, warehouses, roads and railway tunnels is accompanied by more and more transportation of dangerous chemicals, and various fires and leakage accidents occur from time to time, which are often accompanied by a large number of The flammable, explosive, poisonous and harmful gases and smoke will cause great harm to the on-site personnel and the surroun...

AI Technical Summary

Problems solved by technology

[0003] As we all know, in order to increase the exhaust air volume of the smoke exhauster, the driving power of the smoke exhauster must be increased, so the power of the power device driving the smoke exhauster must also be increased accordingly, but as the power increases, its power The volume and weight of the device are also multiplied, and all smoke extractors are equipped with a power unit at present, and the fan is installed on the output shaft of the power unit, so that the power unit will hinder the air intake, so the power unit has to be increased. The diameter of the air duct of the smoke exhauster is large, but because the width of the mobile smoke exhaust equipment is restricted by national regulations, in order to ensure its safety when walking, its width must not exceed 2.5 meters, which greatly limits the exhaust of the smoke exhaust machine. air volume

[0004] In addition, hydraulic motors, engines or conventional motors are generally used as power devices for driving smoke exhausters at present, and as the power increases, the weight and volume of engines or conventional motors also double, and even a heavy vehicle cannot be loaded; The system that uses hydraulic motor as the driving force of the fan, because its power source is provided by the original vehicle motor through the power take-off, coupled with its own power loss and the secondary energy loss generated by converting it into hydraulic energy, greatly limits the exhaust. Increased smoke machine power

[0005] Therefore, looking at the various types of vehicle-mounted fire-fighting and smoke-exhausting equipment currently produced at home and abroad, including the MVU280 smoke-exhaust fire truck made in France, which is currently known as "the smoke-exhaust fire truck with the largest exhaust air volume in the world today", its exhaust air volume is not high. More than 280000 m 3 / h, it is difficult to meet the needs of rapid and effective ventilation, smoke exhaust, cooling, dust removal, and changing the direction of the fire scene for large-scale fires and major petrochemical accidents.

Therefore, first of all, the exhaust air volume of the existing fire-fighting and smoke exhaust equipment is insufficient

[0006] The second is that the fine water mist sprayed with the strong wind does not have the function of decontaminating and neutralizing the toxic gas; the third is that all the high-power vehicle-mounted fire-fighting and smoke-exhausting equipment in the world do not have the function of climbing stairs, even if the smoke emission is small The "Land Rover 60" smoke exhaust robot can only crawl a certain ramp, but cannot go up and down stairs, so it is powerless to fight fires in high-rise buildings, subways and basements

Fourth, none of the above-mentioned smoke exhausters have self-protection devices in case of emergency, so there is no good solution when it encounters an emergency

[0007] At present, all robots used in climbing stairs in the world are intelligent and toy robots, so their volume and weight are small, and they can only carry a small amount of load. No more than 100kg, and because there is no stability and anti-overturning device, it needs the help of accompanying personnel when climbing stairs; and the most advanced German-made "Land Rover 60" smoke exhaust robot in the world, because it uses It is the traditional structural form of the engine-driven hydraulic system, so it is complicated to operate, has a high failure rate, lacks flexibility, and especially cannot be miniaturized. 3 The flow width of the air jet per hour exceeds 1.3 meters, which is far greater than the standard of ordinary building stairs, and due to the limitation of its own volume, the power of the installed engine is small, so its load does not exceed 250kg, and it is impossible to climb stairs at all.
