A protective fire hose

Abstract

The invention discloses a protective fire-fighting water gun. The high-pressure nozzle assembly is a butterfly valve set at the water outlet of the rigid pipe section of the water flow state adjustment mechanism, and the butterfly valve is connected with a valve hand wheel; the water flow state adjustment mechanism includes a water pipe, three fixed pipe seats and three detachable pipe sleeves, and the flexible pipe section In the pressure relief mechanism, the water inlet of the flexible pipe section is connected to the outlet end of the water inlet ball valve, and the water outlet of the flexible pipe section is connected to the water inlet of the rigid pipe section. There is a movable gap between it and the end face of the fixed pipe seat, and the rigid pipe wall corresponding to the gap has a plurality of through holes evenly distributed along the circumference; the water inlet ball valve includes a valve body, a valve core, a handle, and an upper grip. The invention has multiple protection functions, can guarantee personal safety, realizes the elimination of the recoil force of the water gun device, and helps to improve rescue efficiency.

Description

technical field [0001] The invention relates to a water gun structure in the technical field of fire-fighting equipment, in particular to a protective fire-fighting water gun. Background technique [0002] The level of social urbanization is constantly improving, but people's awareness of fire protection is not strong enough, resulting in frequent fires. Especially in the hazardous chemical industry, once a fire and explosion accident occurs, it will often lead to secondary disasters based on the potential domino effect, making the fire last longer, the scope of influence wider, and the consequences of the accident more serious. threaten their personal safety. Therefore, it is of great practical significance to use fire-fighting equipment that includes a "protective" function. [0003] Some fire water guns are disclosed in the prior art, including the fire water gun body, angle adjustment mechanism, and fire water gun shooting aids. This invention can adjust the shooting a...

Problems solved by technology

[0003] Some fire water guns are disclosed in the prior art, including the fire water gun body, angle adjustment mechanism, and fire water gun shooting aids. This invention can adjust the shooting angle and operating state of the fire water gun body, and increase the range of the fire water gun. However, these technologies exist The problems are: 1. The shooting angle can be adjusted directly by changing the hand-held direction, which has no practical significance; 2. The overall design of the fire water gun is relatively large in height and width, and the handheld position does not conform to ergonomic principles; 3. When the water volume is violent When it increases, it will produce strong recoil force, and it will fall left and right, which will affect the stability of the shooting direction and has no protective function.
