Description

Vertical rod type jet arm support

Technical Field

The utility model belongs to the technical field of fire safety, and particularly relates to a vertical rod type jet boom.

Background

The fire disaster of the outer facade of the high-rise building is always a difficult problem of fire control disposal, and the main reason of the fire disaster is that the surface of the building is provided with a combustible heat insulation material, after the outer heat insulation material is on fire, the fire prevention and extinguishing system of the building cannot play a role due to the condition constraints such as position, angle and barriers, and the fire disaster is influenced by factors such as chimney effect, so that the spreading speed of the fire disaster is extremely high, and the fire disaster is easy to spread from outdoor fire to indoor three-dimensional fire, thereby causing more serious consequences. In addition, the high-rise building using the combustible heat-insulating material has huge stock, huge fire hazard and similar accidents in recent years, causes great economic loss and casualties, and generates extremely bad social influence.

Fire protection safety of high-rise buildings is highly dependent on the fire resistance of the building itself and the fixed fire extinguishing facilities. When facing high-rise building facade conflagration, the fire fighting equipment of attacking outward such as high-rise jet car that is commonly used is because lifting height is insufficient, range is not enough, and from the bottom up the stream easily receives molten drop thing, fire plume influence, so can not very effectively function.

The 202310202719.2 high-rise building outer facade movable jet fire extinguishing equipment is special fire extinguishing equipment for the high-rise building outer facade designed for fire rescue workers, is movable and can be communicated with a high-rise building hydrant water source. When the fire extinguishing device is used, the water spraying channel and the jet device are rapidly arranged on the quick-mounting base, and more preferably, the water spraying channel can stretch out and draw back, the jet device can rotate, a distance is extended above a fire floor, water is sprayed back downwards, the coverage area is large, the fire extinguishing effect is good, and the problems that the range and angle are insufficient, the lifting height is insufficient, jet is easily influenced by molten drop, fire plume and other external influences when external attack and rescue equipment such as a lifting jet car is used in the fire extinguishing process of the outer facade of the high-rise building at present can be solved.

The fire extinguishing equipment can be detached and carried, is fast assembled and fixed on site, is convenient to carry and assemble and disassemble, can be flexibly arranged at the position near a firing layer, can be synchronously arranged at multiple points, and forms multiple paths of jet water to cooperatively extinguish a fire. However, when the optimal fire extinguishing frame setting point of the fire extinguishing equipment is the building opening position such as a common window of a high-rise building after a fire disaster occurs, the effective building structure on which the support frame of the fire extinguishing device depends is less, and the support frame is difficult to well find the single-point fixing position, so that quick assembly is formed, and fire extinguishing is performed. Therefore, in order to achieve better fire extinguishing effect, a special supporting frame structure needs to be further designed for the situation that the optimal fire extinguishing frame setting point of the fire extinguishing equipment is positioned at the opening position of a building such as a common window of a high-rise building.
