Water outlet pressurization fire prevention and antifreeze device for fire protection

Abstract

The invention discloses a water outlet pressurizing fireproof anti-icer for firefighting and relates to the technical field of firefighting equipment application. The water outlet pressurizing fireproof anti-icer comprises a firefighting water pipe, a pressurizing pump and a cooling fan. One end of the firefighting water pipe is connected with a water outlet, and the other end of the firefighting water pipe is connected with the pressurizing pump. The part, close to the water outlet, of the firefighting water pipe is connected with cooling fins which are distributed in the radial direction of the water pipe. A closed heat conduction slice is arranged on the exterior of the pressurizing pump, the cooling fan is fixed to the outer wall of a heat conduction box, a speed regulating motor is arranged on the cooling fan, the left side of the cooling fan is connected with an air inlet pipe, and the right side of the cooling fan is connected with a heat transferring box. The water outlet pressurizing fireproof anti-icer effectively solves the problem that the water pressure of the firefighting water pipe is not enough, it is guaranteed that the water outlet cannot be frozen through heat dissipated by the pressurizing pump, it is guaranteed that the water outlet supplies water for firefighting in time, and fire spreading is prevented.

Description

technical field [0001] The invention relates to the technical application field of fire-fighting equipment, in particular to a fire-proof and antifreeze device for pressurizing a water outlet for fire-fighting. Background technique [0002] In the field of fire-fighting equipment application technology, fire-fighting water pipes are widely used, but in cold climates, the outlet of fire-fighting water pipes is easy to freeze, and in the actual fire-fighting process, the timing of fire extinguishing is very important, so it is often necessary to stick to fire-fighting water pipes If necessary, it needs to be thawed by heating with hot water. These preparations are very cumbersome and take a lot of time, which has a serious impact on emergency firefighting tasks; When using a fire hose to extinguish a fire, the problem of water pressure is often difficult to control.

Problems solved by technology

[0002] In the field of fire-fighting equipment application technology, fire-fighting water pipes are widely used, but in cold climates, the outlet of fire-fighting water pipes is easy to freeze, and in the actual fire-fighting process, the timing of fire extinguishing is very important, so it is often necessary to stick to fire-fighting water pipes If necessary, it needs to be thawed by heating with hot water. These preparations are very cumbersome and take a lot of time, which has a serious impact on emergency firefighting tasks; When using a fire hose to extinguish a fire, the problem of water pressure is often difficult to control. If the pressure pump is too far away from the water outlet, the pressure reaching the water outlet will be insufficient. However, if the pressure of the pressure pump is increased, it will greatly shorten the fire fighting time. The service life of the water pipe has brought great troubles to the fire protection application; in a relatively complicated fire scene, when the firefighters hold the water outlet of the fire water pipe to extinguish the fire, the fire may spread to the water outlet of the fire water pipe, which may affect the firefighters. impact on life safety
