Shoulder supporting type high-pressure fine mist firefighting lance

Abstract

The invention discloses a shoulder-supporting high-pressure fine-mist fire-fighting water gun, which comprises a water gun tube, a fire-fighting nozzle, a control handle, a water chamber, a shoulder rest, a side pressure relief pipe, a safety pressure relief valve and a connecting hinge; one end of the water gun tube is provided with a A fire sprinkler head is provided with water outlet pores inside the fire sprinkler head. The other end of the water gun tube is provided with a water chamber, and a water pipe interface is provided on the side wall of the water chamber. The water gun tubes are connected through a connecting hub, one end of the water chamber is fixedly connected to a shoulder rest, the top of the water chamber communicates with the middle of the water gun tube through a side pressure relief pipe, and a safety relief valve is arranged at the water inlet of the side pressure relief pipe , the outside of the side pressure relief pipe is provided with a threshold adjustment mechanism for the safety relief valve, and the bottom of the water gun pipe is provided with a control handle. During the working process of the present invention, the side pressure relief pipe cooperates with the safety relief valve to prevent sudden The effect of permanent high-pressure water flow and pulse jet on the damage of fire sprinklers improves the service life of fire sprinklers.

[0002] At present, fire protection work is a highly social work. Only by relying on the strength of the whole society can it be done well with the care, attention, support, and participation of members of the whole society. The social nature of fire fighting tools; fire management should penetrate into In all areas of human life and harvest, it determines the social nature of fire protection work; fire safety management involves all walks of life, and even thousands of households. In the process of production, work and life, people have little omissions in fire safety management A momentary loss of focus, loss of control, or mistakes in production may cause a fire, which determines the regularity of firefighting work; looking at the lessons learned from fire accidents over the years, although the causes of disasters are complicated, it can be seen that the vast majority of fires are caused by Due to the mistakes of one person, one thing, and one moment, this makes us further clarify a truth that only the active participation of the people can control and eliminate the occurrence of fire accidents, which determines the mass nature of fire protection work. However, the existing technology , there are often some defects in the fire fighting process, and it is impossible to quickly and effectively extinguish the fire

[0003] For this reason, Chinese patent CN205042014U discloses a kind of high-pressure water mist fire-fighting water gun with LED lamp, including water gun tube, fire-fighting nozzle, switch handle, connecting part, shoulder rest, LED lamp and connecting hub, and one end of described water gun tube is provided with There is a fire sprinkler head and a water outlet hole arranged inside the fire sprinkler head. The other end of the water gun tube is provided with a connecting part and a water pipe interface arranged on the connecting part. The connecting part and the water gun tube are connected through a connecting hub. One end of the connection part is provided with a shoulder rest, the bottom of the water gun tube is provided with a switch handle, and the inside of the water gun tube is provided with an inner cavity. This invention can realize long-term spraying of water mist and reduce the working pressure of firefighters; but in the actual application process Among them, the invention cannot have good elimination or preventive measures for sudden high-pressure water inlet jets or pulse jets, resulting in very uniform structural damage to fire sprinklers, which in turn affects the overall service life of fire sprinklers
