Multi-core-driven multistage-pressurization combined type fire-fighting and smoke-exhausting device

Abstract

The invention discloses a multi-core-driven multi-stage pressurized combined fire-fighting smoke exhaust device, comprising a carrier, a rotary lifting mechanism is arranged on the carrier, a combined smoke exhaust unit is fixedly installed on the rotary lifting mechanism, and a control device is also arranged on the carrier. The system, the control system is connected with the combined smoke exhaust unit. The combined smoke exhaust unit is fixedly installed by a combination of 6 smoke exhausters. Each row is set with 3 smoke exhausters, and two rows of sets are set up and down. The hood is installed with a shared cover air duct, water supply pipeline and fine water mist nozzle. The multi-core-driven multi-stage pressurized combined fire-fighting and smoke-exhausting device of the present invention has a large exhaust air volume when the volume of the fire-fighting and smoke-exhausting device is constant.

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...

AI Technical Summary

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 largest smoke-exhausting fire truck in the world, its exhaust air volume does not exceed 280,000m3 / 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
