Fire gun of high-rising building outer wall

Abstract

The invention provides a fire gun of a high-rising building outer wall, which comprises a handle pipe and a sparge pipe, wherein the sparge pipe is installed at one end of the handle pipe, and a blow hole is arranged on the sparge pipe. The fire gun is characterized in that: the fire gun has a simple structure, is low in cost, and adopts the telescopic spray extinguishment, so the extinguishment scope is increased, the vertical spreading fire of an outer wall surface can be effectively stopped, the functions of cooling and extinguishment are obtained, during the initial fire period, personnel in a high-rising building connect the fire gun through a water hose in a wall fire hydrant for initial arrangement, so precious time for successful fire suppression is obtained, because the fire gun is provided with the handle pipe, an operator does not need to lean out of a window to operate, so the personnel safety of the operator is ensured, a switch which is arranged on the handle pipe brings more convenience to the operation, and only one person can complete the operation.

Description

technical field [0001] The invention relates to a fire-fighting equipment, in particular to a high-rise outer wall fire extinguishing gun. Background technique [0002] In recent years, with the development of cities, high-rise buildings have sprung up like mushrooms after a spring rain. However, high-rise fires are also emerging one after another. Especially, the exterior walls and facades of high-rise buildings are not included in the protection scope of internal fire protection facilities. Once a fire occurs, the fire spreads quickly. It is very difficult to fight fires. At present, traditional fire extinguishing methods are used for fires on the outer walls of high-rise buildings: for example, firefighters at the bottom of high-rise buildings use fire-fighting ladders, vehicle-mounted water cannons and other fire-fighting equipment to extinguish the fire. However, this fire-fighting method is subject to many limitations. Equipment such as fire ladders The climbing abilit...

[0002] In recent years, with the development of cities, high-rise buildings have sprung up like mushrooms after a spring rain. However, high-rise fires are also emerging one after another. Especially, the exterior walls and facades of high-rise buildings are not included in the protection scope of internal fire protection facilities. Once a fire occurs, the fire spreads quickly. It is very difficult to fight fires. At present, traditional fire extinguishing methods are used for fires on the outer walls of high-rise buildings: for example, firefighters at the bottom of high-rise buildings use fire-fighting ladders, vehicle-mounted water cannons and other fire-fighting equipment to extinguish the fire. However, this fire-fighting method is subject to many limitations. Equipment such as fire ladders The climbing ability is limited, it is not easy to get close to the high-rise fire point, and it is impossible to extinguish the fire above the fire ladder's climbing limit, and this method is to extinguish the fire from the bottom up, and the firefighters cannot see the fire point above at all, and cannot accurately extinguish the flames; For example, firefighters in high-rise buildings use the indoor fire hydrant fire extinguishing system in the high-rise to spray water from the inside to the outside to stop the fire. The range is small, and it is impossible to spray fire effectively, and some even cannot spray to the fire area. Moreover, due to the structural limitation of the gun, the operator must stick his head and body out of the window for operation. Under the fierce fire and thick smoke, personal safety pose a great threat
