Fire-fighting truck capable of supplying water in long distance

Abstract

The invention discloses a fire-fighting truck capable of supplying water in long distance. The fire-fighting truck capable of supplying water in long distance comprises a fire-fighting truck body, wherein a water channel structure on the fire-fighting truck comprises a water pump; discharged water of the water pump is divided into two paths; one path is connected with a washing water tank, and the other path is connected with a fire fighting water hose; a water inlet pipeline connected with a water inlet of the water pump is divided into a pipeline A and a pipeline B; the water inlet pipeline A comprises a check valve A, a water discharging ball valve A and a vacuum pump; the water inlet pipeline B comprises an automatic backwashing filter, a check valve B and a butterfly valve which are sequentially connected with one another in series. The fire-fighting truck body is also provided with an automatic water hose winding and unwinding device, a hose winding guiding device and a foldable step ladder. By virtue of the fire-fighting truck capable of supplying water in long distance, the requirements on a water source for long-distance fire-fighting water supply and winding, unwinding and washing of the fire-fighting water hose can be effectively met, and the long-distance fire-fighting water supply requirements are met; the fire-fighting truck capable of supplying water in long distance has a significant industrial application value and can be widely popularized and applied.

Description

technical field [0001] The invention relates to a fire truck capable of long-distance water supply and belongs to the technical field of fire fighting equipment. Background technique [0002] With the increase of natural disasters (such as droughts, earthquakes) and the frequent occurrence of large-scale fires, the distance between the accident area and the water source is often long, and the water cannot be transported to the accident area in time. The water source is transported to the long-distance water supply fire truck in the accident area. [0003] Because the waterway structure of fire trucks in the prior art usually has only one water suction booster mode, which is to install a filter screen at the inlet of the water pump, it is only suitable for relatively clean water sources. If the water source is not very clean, blockage may occur during use, and when stones or other large particles of hard debris enter the pipeline, the water pump will be damaged; in addition,...

AI Technical Summary

Problems solved by technology

If the water source is not very clean, blockage may occur during use, and when stones or other large particles of hard debris enter the pipeline, the water pump will be damaged; in addition, long-distance water supply requires the laying of long-distance fire hoses, In the prior art, the laying of the fire hose is mainly done manually; and at the end of each firefighting operation, the fire hose needs to be cleaned and reeled again for transportation and next use, while the prior art The cleaning and reeling of fire hoses are mainly done manually; if this long-distance firefighting operation still relies on manual cleaning and rewinding of long-distance fire hoses, the following difficulties will inevitably occur: 1) combat personnel The manual labor intensity is very high, and the operation efficiency is low; 2) Since the fire hose is very long, it is easy to change the direction of the hose repeatedly during the reel process, which not only makes the operation of the reel difficult, but also has high labor intensity, time-consuming and labor-intensive work. Low, and affect the quality and appearance of the tape; 3) Since the surface of the fire hose after the remote firefighting operation is usually covered with a lot of weeds, sludge, stones and other debris, manual cleaning is also very troublesome
