Portable heat flow barrier device for fire scene combat

Abstract

The invention discloses a portable heat flow blocking device for actual combat on the fire scene, which solves the problem that the life of firefighters and trapped persons in the fire field is in danger of life in a high heat radiation environment. The invention includes a cart, a water tank and a heat flow blocking mechanism; the heat flow blocking mechanism includes a steel wire grid frame for placing on a fire scene to generate a water curtain to reduce radiant heat flow, a water delivery hose connected to the water tank, and a water delivery hose The water pump on the top, and the water spray assembly installed in the wire mesh frame and connected with the water delivery hose to spray fan-shaped water curtain to the wire mesh frame, the water pump is fixed on the top of the water tank, and the water pump sends the clean water in the water tank through the The water hose is pumped to the water spray assembly, and the water spray assembly sprays the clean water delivered by the water delivery hose onto the steel wire mesh frame in a fan shape, so that the steel wire mesh frame continues to produce a uniform water curtain to reduce the radiant heat flow at the fire site. It can be equipped and used at the scene of fire rescue, and has the characteristics of blocking heat flow, light weight, mobility, long fire resistance time, and good heat resistance effect.

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
