Portable heat flow insulating device for actual fire scenes

Abstract

The invention discloses a portable heat flow insulating device for actual fire scenes. The device solves the problem that firefighters and trapped persons in a fire scene have life risk in a high heatradiation environment. The device comprises a trolley, a water tank and a heat flow insulating mechanism, wherein the heat flow insulating mechanism comprises a steel wire net rack, a water conveyinghose, a water pump and a water spraying assembly, wherein the steel wire net rack is placed in the fire scenes to generate water curtains to reduce radiation heat flow, the water conveying hose is connected with the water tank, the water pump is arranged on the water conveying hose, and the water spraying assembly is arranged in the steel wire net rack, connected with the water conveying hose andused for spraying the sector-shaped water curtains onto the steel wire net rack; and the water pump is fixed at the top of the water tank, the water pump pumps clean water in the water tank to the water spraying assembly through the water conveying hose, and the water spraying assembly sprays the clean water conveyed by the water conveying hose onto the steel wire net rack in a sector shape and makes the steel wire net rack continuously generate uniform water curtains to reduce the radiation heat flow of the fire scenes. The device can be used in fire scene rescue equipment, and has the characteristics of heat flow insulation, light weight, movable performance, long fire resistance time, good heat resistance effect and the like.

Description

technical field [0001] The invention relates to a portable heat flow blocking device for actual combat on the fire scene. Background technique [0002] When a fire breaks out, the thermal radiation generated by the high-temperature flame and high-temperature smoke will accelerate the spread of the fire and threaten the lives of fire rescuers. In fire protection engineering, fire separation technology is usually used to block heat radiation and prevent fire from spreading. [0003] At present, the main fire partitions include firewalls, fire doors and fire shutters. Firewalls, fire shutters, and fire doors may fail in the event of a fire, and once the fire shutters and fire doors are closed, it will be difficult to evacuate personnel and prevent firefighters from entering the fire scene for disaster relief. [0004] Firewall is an important separation component to prevent the spread of fire between buildings. It can effectively confine the fire to a certain space in the ini...

Problems solved by technology

Due to factors such as the weight and fire-resistant time of the fire door, it cannot be directly applied to the fire scene to achieve heat flow barrier
