Alloy ribbon heater for freezing prevention of tunnel fire-fighting pipeline

Abstract

The invention discloses an alloy ribbon heater for freezing prevention of a tunnel fire-fighting pipeline. The alloy ribbon heater comprises an anti-freezing device, a connecting device and an external device, the connecting device is fixedly connected to the outer surface of the anti-freezing device, and the external device is fixedly connected to the outer surface of the connecting device. The anti-freezing device comprises a fire-fighting pipeline, a sponge layer, a waterproof layer, a first hook-and-loop fastener, a second hook-and-loop fastener, a clamping groove, a clamping plate, a first extrusion ball and a second extrusion ball, and the second hook-and-loop fastener is arranged on the outer surface of the fire-fighting pipeline. The anti-freezing device and the connecting device are arranged, so that the sponge layer, the waterproof layer, the alloy woven layer and the heating layer are tightly fixed to the outer surface of the fire-fighting pipeline, the anti-freezing effect of the fire-fighting pipeline in winter is improved, water in the fire-fighting pipeline is prevented from being frozen, the fire-fighting pipeline can be normally used when a fire breaks out, and potential safety hazards are avoided.

Description

technical field [0001] The invention belongs to the technical field of fire-fighting pipeline protection, in particular to an alloy electric heating belt for anti-freezing of tunnel fire-fighting pipelines. Background technique [0002] Due to the special environment inside the tunnel, fires are prone to occur and spread very quickly and cause great harm. If a fire occurs if it is not dealt with in time, if it cannot be discovered and extinguished in time, the fire will spread rapidly along the longitudinal direction of the tunnel, causing passengers in the tunnel to Asphyxiation, burns, poisoning and even death of the staff, the fire in the tunnel often ends in causing a large number of casualties. However, in the severe winter, the problem of the pipeline is particularly prominent. The water freezes, so that the fire pipes can be used normally in winter. However, the existing antifreeze devices for fire pipes simply wrap sponge on the outer surface of the fire pipes. The a...

[0002] Due to the special environment inside the tunnel, fires are prone to occur and spread very quickly and cause great harm. If a fire occurs if it is not dealt with in time, if it cannot be discovered and extinguished in time, the fire will spread rapidly along the longitudinal direction of the tunnel, causing passengers in the tunnel to Asphyxiation, burns, poisoning and even death of the staff, the fire in the tunnel often ends in causing a large number of casualties. However, in the severe winter, the problem of the pipeline is particularly prominent. The water freezes, so that the fire pipes can be used normally in winter. However, the existing antifreeze devices for fire pipes simply wrap sponge on the outer surface of the fire pipes. The antifreeze effect is not good, and it cannot prevent the fire pipes from The water inside freezes, causing the fire pipes to fail to work normally and causing safety hazards
