Fire-fighting waterway heating equipment for fire-fighting vehicles in cold regions

Abstract

The invention belongs to the technical field of fire protection, in particular to a fire-fighting waterway heating equipment for fire trucks in cold regions, which includes a plurality of waterway pipes. The joints are connected to form the whole fixed waterway in the fire truck. The outer wall of the waterway pipeline is fixed with a thermal insulation shell, and a heat exchange chamber is formed between the thermal insulation shell and the outer wall of the waterway pipeline, and a circulation cavity is arranged inside the waterway pipeline. The present invention makes the air flow in the middle of the circulation cavity recoil to both ends, so as to realize the rapid disturbance of the air flow in the flow cavity through the heat exchange rate difference and improve the actual heating efficiency, and cooperate with the air pressure difference caused by heating and the swaying of the fire truck when driving The resulting expansion and contraction of the first spring drives the reciprocating motion between the two piston rings, improving the actual heating efficiency of the water pipeline.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a fire-fighting waterway heating device for fire-fighting vehicles in cold regions. Background technique [0002] Fire trucks, also known as fire trucks, refer to vehicles that are designed and manufactured to be suitable for firefighters, equipped with various fire-fighting equipment or fire-extinguishing agents, and used by fire-fighting forces for fire-fighting, auxiliary fire-fighting or fire-fighting rescue. Modern fire trucks usually It will be equipped with steel ladders, water guns, portable fire extinguishers, self-contained breathing apparatus, protective clothing, rescue tools, first aid tools and other equipment, and some will also be equipped with large fire extinguishing equipment such as water tanks, water pumps, and foam fire extinguishing devices.

Problems solved by technology

[0003] In addition to the hoses used to connect the waterway externally, the fire trucks used today are often connected with fixed water pipes between the body and the pump body, especially in fire trucks equipped with water tanks and pumps. However, when this type of fire truck is used in a cold area, when the fire truck is not used, the inner and outer walls of the fixed pipe are often caused by residual water or contact with the water tank or external air. Membranes are not used for water delivery and firefighting, or because of the direct passage of a large amount of water, it is easy to cause damage to the fixed waterway pipeline, which often needs to be heated before use. In the prior art, the waterway pipeline composed of fixed steel pipes is heated, or in the The periphery of the water pipe is completely wrapped with a heating sleeve for heating, but the energy loss of the heating sleeve is too large when it is completely wrapped around the water pipe, or it is heated at multiple single points, but the poor heating and thawing effect will take time and will affect the emergency. fire fighting effect, so the existing technology has poor emergency heating effect on the waterway of fire trucks
