Abstract
Description
Technical Field
[0001] The present application relates to the field of heat preservation of fire extinguishing boxes, and in particular to a fire extinguishing box with electric heating. Background Art
[0002] The fire extinguisher box is a fixed fire-fighting equipment, and its main function is to control combustibles, isolate combustion-supporting materials, and eliminate ignition sources. Due to the relatively low ambient temperature in the north in winter, various liquid delivery pipes are frozen to varying degrees, and even burst, which has a serious impact on people's work and life. Fire-fighting pipes are closely related to people's lives and are of even greater significance. As an effective antifreeze solution for fire-fighting pipes, electric heating cables have been widely used in fire-fighting pipelines and underground garage sprinkler systems. Its working principle is to compensate for the heat loss of the heated pipes through direct or indirect heat exchange through the heat dissipated by the electric heating cables, so as to meet the requirements of antifreeze and heat preservation, and ensure the normal use of fire-fighting pipes in severe winter.

The extension height of the top of the heating cable is higher than the top of the fire pipe, and it is turned back and laid at the height of the fire hydrant head. When turning back, it passes through the top of the side pipe of the fire pipe and turns back again, and returns to the side of the fire pipe close to the box body. The heating cables are evenly laid on the fire pipe, and the turning back laying method is adopted, which reduces the number of heating cables and reduces the possibility of their entanglement. A fire box with electric heating according to the present application can not only meet the stable insulation of the pipes in the fire box, but also ensure that the electric heating belt is not entangled, thereby facilitating the operation and maintenance of the fire box.
