Embodiment 1

[0023] Such as figure 1 As shown, the fire-fighting water gun for the outer wall of a high-rise building designed in this embodiment is composed of a gun head 1 and a gun barrel 2, the gun barrel 2 and the gun head 1 can be separated, and the gun head 1 and the gun barrel 2 are connected together by an interface 3, Gun barrel 2 length is 0.3 meters, and gun barrel 2 lengths are not enough to connect one or several again, until the water that water gun sprays can spray water to high-rise building exterior wall. The water gun head 1 is designed to have an adjustable bending angle of 40°-90°, which can be adjusted according to the position of the ignition point when extinguishing the fire. The diameter of the water gun barrel 2 is 25mm. The front end of the water gun head 1 is the nozzle 4, and the front end of the nozzle 4 is the water nozzle. 5. The water spray port 5 is a flat mouth shape, the length of the water spray port 5 is 50mm, and the net water discharge thickness of t...

Embodiment 2

[0025] Such as Figure 4 As shown, the fire-fighting water gun for the outer wall of a high-rise building in this embodiment, the gun head 1 and the gun barrel 2 are integrated, the angle of the broken line of the gun head 1 is designed to be 60 °, which is a fixed angle, the diameter of the water gun gun barrel 2 is 65mm, and the water gun gun head 1 The front end is the nozzle 4, the front end of the nozzle 4 is the water spray port 5, the water spray port 5 is flat, the length of the water spray port 5 is 150mm, the net water thickness of the water spray port 5 is 35mm, the rear end of the nozzle 4 is cylindrical, and the cylinder Diameter is identical with gun barrel 2 diameters, and the distance of water spout 4 and nozzle 2 rear ends is 100mm, and the material of whole water gun is aluminum alloy, and present embodiment design structure is simple, and cost is lower, easy to use.

Abstract

The invention relates to the technical field of fire engineering and machinery manufacturing, in particular to a fire-fighting lance for outer walls of high-rise buildings, which comprises a lance head and a lance tube, wherein the lance head is a broken line with an angle of 40-90 DEG; the angle of the lance can be an adjustable angle or fixed angle; the lance head and the lance tube are integrated or connected together through a port; the front end and the rear end of the lance tube are provided with ports, the diameter of the lance tube is 10-150 mm, the length of the lance tube is 0.22 m; the front end of the lance head is provided with a nozzle, the rear end of the lance head is provided with a port, the front end of the nozzle is provided with a water injection nozzle which is shaped as a flat opening, the length of the water injection nozzle is 30-300 mm, the purified water thickness of the water injection nozzle is 5-80 mm, the rear end of the nozzle is shaped as a cylinder, the diameter of the cylinder is equal to the diameter of the lance tube, and the distance from the water injection nozzle to the rear end of the nozzle is 30-300 mm. The lance head is designed to be of a broken line hooked towards the lance tube, thus the purpose of spraying water on the outer walls of the high-rise buildings for fighting fire from the inside of the high-rise buildings is achieved.

Description

technical field [0001] The invention relates to the technical field of fire protection engineering and machinery manufacturing, in particular to a fire-fighting water nozzle for the outer wall of a high-rise building. Background technique [0002] The fire water gun is a water jet tool for fire extinguishing. When it is connected with a hose, it will spray dense and substantial water flow. It has the advantages of long range and large water volume. According to different jet forms and characteristics, it can be divided into: direct current water gun, spray water gun, multi-purpose water gun and multi-functional fire water gun. The commonly used water guns are direct current and spray water guns. [0003] DC water gun: The water jetted by the DC water gun is columnar, with long range, large flow rate and strong impact. It is used for extinguishing general solid material fires and auxiliary cooling when extinguishing fires. Generally can be divided into ordinary DC water gu...
