Problems solved by technology

However, in the process of actually using the fire water cannon, the speed of water spraying from the nozzle is very high. Changing the number of the gun barrel when the nozzle sprays water may cause the sprayed water column to cause injury to the firefighters. Spraying water and then adjusting the number of barrels will affect the fire extinguishing efficiency

Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] like figure 1 Shown, a kind of fire-fighting water cannon with adjustable firing range comprises cannon body 4, is used to support the supporting base 2 of cannon body 4 and the annular handrail 3 and gun barrel 1 that are fixedly arranged on the cannon body 4, and the cannon body 4 and support The seat 2 is ball-hinged, and the support seat 2 is provided with several bolt holes 21 . The gun barrel 1 includes a fixed pipe 11 fixedly connected to the gun body 4, a gathering water pipe 13 of the water outlet, and several adjustment pipes 12 connecting the fixed pipe 11 and the gathering water pipe 13. Here, it is set as an adjustment pipe 12, and the outer wall of the adjustment pipe 12 is fixedly arranged There is a first adjustment handle 121 .

[0034] like figure 2 As shown, the above-mentioned fixed pipe 11 and the gathering water pipe 13 are re...

Abstract

The invention relates to a fire water monitor with an adjustable range. The fire water monitor with the adjustable range comprises a gun body, a supporting seat for supporting the gun body, handrailsand a gun barrel, wherein the handrails and a gun barrel are fixedly arranged on the gun body, wherein the gun body is in spherical hinge connection with the supporting seat; the gun barrel comprisesa plurality of adjusting pipes which are rotatably connected; and a plurality of water blocking stopping-blocks which are arranged at intervals are arranged in the circumferential direction of the inner walls of the adjusting pipes. Due to the arrangement of the adjusting pipes, when the adjusting pipes are relatively rotated, the water blocking stopping-blocks of different adjusting pipes can bestaggered with one another, so that the function of adjusting the cross-sectional area of water flowing of the gun barrel is achieved. When the water yield of a fire fighting truck is a certain value,the water flowing area of the gun barrel changes, so that the change of the water flow speed of a water column sprayed from the gun barrel is achieved, and the purpose of adjusting the water sprayingdistance of the fire water monitor in the water spraying process of the fire water monitor is achieved.

Description

technical field [0001] The invention relates to the field of fire-fighting equipment, in particular to a fire-fighting water cannon with an adjustable shooting range. Background technique [0002] Because of the advantages of long range and high fire extinguishing efficiency, fire water cannon is an important tool for quickly extinguishing large fires, and is widely used in various occasions. As an indispensable and important part of the fire water monitor, the nozzle head is the last link in the energy conversion of pressure water, which determines the final spraying mode of the fire water monitor, and its performance directly affects the performance of the water jet of the fire water monitor. Modern fires have the characteristics of fast burning speed, fierce fire intensity, high fire scene temperature, and difficulty for firefighters to approach, which requires spraying fire extinguishing agent from as far away as possible. The high-performance gun head can not only impr...
