Problems solved by technology

For extra-large fires, especially petrochemical fires, such as blowouts, natural gas leakage and other large-scale accidents, the existing smoke exhausters are not effective because of insufficient exhaust air volume.
[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, which will make the power unit hinder the air intake, so that the power unit has to be increased. The diameter of the air duct of the smoke exhauster is large, but because the height and width of the mobile smoke exhaust equipment are restricted by national regulations, its height must not exceed 4 meters and its width must not exceed 2.5 meters, thus greatly limiting the exhaust performance of the smoke exhaust machine. air volume
[0004] In addition, hydraulic motors, various engines and conventional motors are generally used as power devices for driving smoke exhausters at present. With the increase of power, the weight and volume of hydraulic motors, engines or conventional motors are also doubled, and even a heavy vehicle can't fit
[0005] Therefore, looking at the various types of vehicle-mounted fire-fighting and smoke-exhausting equipment currently produced at home and abroad, including the smoke-exhausting fire truck MVU280, which is currently known as the world's largest smoke-exhaust fire truck, its exhaust air volume cannot exceed 280,000m 3 / h, it is difficult to meet the needs of fast and effective ventilation, smoke exhaust, cooling, dust removal, and changing the direction of the fire scene for large-scale fires and major petrochemical accidents

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] The overall structure of the combined fire-fighting and smoke-exhausting device of the present invention, such as figure 1 As mentioned above, the combined fire-fighting and smoke exhaust device 1 includes a combined smoke exhaust unit 2 , a rotary lifting mechanism 3 and a control system 4 . The combined smoke exhaust unit 2 is fixedly installed on the rotary lifting mechanism 3, and the upper part of the rotary lifting mechanism 3 is hinged with the combined smoke exhaust unit 2, so that the combined smoke exhaust unit 2 can realize the functions of rotation, pitching and lifting; the rotary lifting The bottom of the mechanism 3 is fixedly installed on a mobile or fixed carrier 5 . A control system 4 is also arranged on the carrier 5. The control system 4 can be a wireless control system or a wired control system. The present invent...

Abstract

The invention discloses a multi-core-driven multi-stage booster combined fire-extinguishing and smoke-controlling device which comprises a carrier. The carrier is provided with a rotating lifting mechanism which is fixedly provided with a combined exhaust blower group, the carrier is also provided with a control system which is connected with the combined exhaust blower group formed by assemblingand fixedly mounting six exhaust blowers together, and the six exhaust blowers are arranged up and down and integrally combined in two rows with three exhaust blowers in a row and share an outer air duct, a water supply pipeline and a water mist nozzle. The multi-core-driven multi-stage booster combined fire-extinguishing and smoke-controlling device of the invention has great exhaust air rate incase of a certain volume.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting devices, and relates to a multi-stage pressurized combined fire-fighting and smoke-exhausting device driven by multiple cores. Background technique [0002] Due to the urbanization process and the continuous acceleration of the modern industrial revolution, various large-scale fires and leakage accidents of dangerous chemicals have occurred from time to time. This type of accident is often accompanied by a large amount of flammable, explosive and toxic gases and smoke, which causes great harm to the on-site personnel and the surrounding environment, and brings great difficulties and risks to fire fighting and on-site rescue. According to statistics, more than 85% of the people in the fire died due to inhalation of toxic fumes, far more than the people burned to death in the fire. At present, the most effective fire fighting measure is to use positive pressure or negative pressure smoke exha...
