Visible universal fire-fighting lance

Abstract

The invention discloses a visible universal fire-fighting lance which comprises a nozzle, a high pressure steel wire hose, a ball valve, a lance base and a direction adjusting rod. The two ends of the high pressure steel wire hose are provided with connectors correspondingly. The two connectors are in threaded connection with the nozzle and the ball valve correspondingly. The end, away from the corresponding connector, of the ball valve is in threaded connection with the lance base. The end, close to the nozzle, of the corresponding connector is provided with a first rotating shaft. The end, close to the ball valve, of the connector is provided with a second rotating shaft. The visible universal fire-fighting lance has the beneficial effects that when a fire of jet flow dead corners below a room beam, a window and the like needs to be put out by a firefighter on a fire field, the firefighter only needs to stand on a door or window, the wall of a building is used as a shield, the bending degree of the high pressure steel wire hose of the fire-fighting lance is adjusted through front-back pulling and retraction of the a handle, the water flow direction is changed, dead-corner-free fire extinction is achieved, safety of the firefighter is protected, meanwhile, a wireless camera collects images in real time and transmits the images to the firefighter, and the accurate position and fire intensity of a fire point are commanded.

Description

technical field [0001] The invention mainly relates to the field of fire-fighting technical equipment, in particular to a visible universal fire-fighting water gun. Background technique [0002] Fire-fighting water guns are water jetting tools for fire-fighting. According to different jet forms and characteristics, fire-fighting water guns can be divided into: DC water guns, spray water guns, multi-water guns, etc. Among them, the commonly used water guns are DC water guns. The water flow sprayed by the DC water gun is columnar and has a strong impact, but it cannot change the direction of the water flow during use. When a fire occurs, there are many places that firefighters cannot directly enter. However, if the existing fire-fighting water gun is used to extinguish the fire on the beams and under the windows of the house, the water flow cannot be directly hit, and there will be a dead angle of the jet flow, which cannot exert the maximum effect of the water gun to extingui...

Problems solved by technology

The water flow sprayed by the DC water gun is columnar and has a strong impact, but it cannot change the direction of the water flow during use. When a fire occurs, there are many places that firefighters cannot directly enter. However, if the existing fire-fighting water gun is used to extinguish the fire on the beams and under the windows of the house, the water flow cannot be directly hit, and there will be a dead angle of the jet flow, which cannot exert the maximum effect of the water gun to extinguish the fire. Improvements have been made, and a direction-changing elbow is installed at the front end of the fire water gun to realize the direction-changing of water flow, so that firefighters can extinguish fire or cool down places with jet dead angles without entering the room, but the angle of the direction-changing elbow is fixed. Due to the lack of a special direction adjustment device, it is impossible to extinguish the fire at any angle indoors due to the limitation of the rotation angle. In addition, the direct-current water nozzle and the direction-changing water nozzle cannot be directly switched and used. Firefighters need to disassemble and replace the direction-changing elbow on site, which may delay fire extinguishing If the fire in the dead corner is relatively large, firefighters need to enter the room to extinguish the fire. Once they encounter collapse or explosion during the fire fighting process, the lives of firefighters will be endangered. If the fire in the dead corner is small, the firefighters will not Small fires that can lead to jet dead ends can grow into major fires with serious consequences, found

[0003] In addition, firefighters cannot directly observe the fire situation and grasp the exact location of the fire when they are extinguishing the fire in places with jet blind spots outdoors.
