Novel fire-fighting lance capable of spraying fire extinguishment balls

Abstract

The invention discloses a novel fire-fighting lance capable of spraying fire extinguishment balls. The novel fire-fighting lance comprises a lance barrel. A lance tail sealing ring is arranged at theupper left end of the lance barrel and is connected with the lance barrel in a nested manner. A lance barrel sealing ring is arranged at the upper left end of the lance tail sealing ring and is connected with the lance tail sealing ring in a nested manner. A muzzle sealing ring is arranged at the upper left end of the lance barrel sealing ring and is connected with the lance barrel sealing ring ina nested manner. A lance sleeve is arranged at the left end of the muzzle sealing ring and is fixedly connected with the muzzle sealing ring. A valve box is arranged at the rear end of the lance barrel and is fixedly connected with the lance barrel. According to the fire-fighting lance capable of spraying the fire extinguishment balls, the fire extinguishment balls are adopted for fire extinguishment, when ignited, the fire extinguishment balls quickly expand and burst in a shell, a dry powder extinguishing agent is rapidly sprayed to a protection area and is quickly diffused around, a totalflooding fire extinguishing state is formed, and therefore both quick fire extinguishing and large-area extinguishing can be achieved.

Description

technical field [0001] The invention relates to the technical field of a fire-fighting water gun capable of spraying fire-extinguishing balls, in particular to a fire-fighting water gun capable of spraying fire-extinguishing balls. Background technique [0002] The development of fire-fighting water guns that can spray fire-extinguishing balls. In the early days, there were no water pipes and water pumps. When a fire broke out, people usually used containers, such as buckets, to manually carry water from the water source to the fire. At that time, this was the only way to extinguish fire. Way, in 1518, Antony Blatner, a craftsman who made metal crafts, made the world's first fire engine. In 1666, someone in England invented the world's first fire engine with a hand pump. In 1673, Jan Bendel Hayden invents a water hose made of leather for fire fighting. At the end of the 19th century, the internal combustion engine gradually replaced the steam engine, and fire trucks appeare...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a fire-fighting water gun capable of spraying fire-extinguishing balls to solve the problem in the above-mentioned background technology that different fire-fighting water guns are selected corresponding to different fire scenes, which are not portable enough, inconvenient to transport, and the fire-extinguishing speed is slow and cannot be used in large areas. For fire extinguishing, the spraying distance is not far enough, and there may be insufficient water supply, so that the flames cannot be completely extinguished, and even the traditional water gun is used rashly without knowing the cause of the fire, causing secondary disasters.
