Folding hydraulic power auto- swing fire nozzle

Abstract

The invention discloses a folding hydraulic power auto-swing fire nozzle, comprising a nozzle, a handle operating mechanism, an outlet bend pipe, a positioning locking mechanism, a inflow bend pipe, a vertical shaft, a connecting rod base I, a connecting rod I, a butterfly bolt, a connecting rod II, a connecting rod base II, a sliding block locking mechanism, a sliding block, a round driving disc, a impeller, a driving shell, a cone gear I, a cone gear II, a chassis, a horizontal locking mechanism, a mother board, a stabilizer positioning mechanism and a stabilizer. The impeller is driven by press water to rotate, a pair of cone gears which are meshed with each other are driven by the impeller to pass a horizontal rotating to a vertical direction and the nozzle is driven to swing by a crank connecting link mechanism which is composed of the sliding block, the round driving disc, the connecting rod and the inflow bend pipe. The spraying with a certain of pitch angle and swing frequency can be realized by the fire nozzle in a broad coverage area; the operation is flexible without human intervention; the folded floor area of the invention is small, thus applicable to storing and moving. The invention is especially suitable to the extinguishing situation in which people are difficult to approach and the fire nozzle needs strong mobility.

Description

Technical field [0001] The invention relates to fire fighting equipment, in particular to a foldable hydraulic self-swinging fire fighting water cannon. Background technique [0002] The fire-fighting water cannon is a fire-fighting equipment that converts water with a certain pressure and a certain flow rate into kinetic energy through energy conversion, and sprays it from the nozzle of the nozzle at a high speed to form a jet to extinguish a fire at a certain distance. It has the characteristics of long-distance fire extinguishing, cooling protection, high fire extinguishing efficiency and high power in safe areas outside the fire radiant heat, explosion hazard, and toxic smoke areas. It is the most widely used fire extinguishing equipment in actual fire fighting. [0003] Classified according to different power sources, fire water monitors can generally be divided into three categories: hydraulic control fire water monitors, electric control fire water monitors and hydrau...

AI Technical Summary

Problems solved by technology

This structure is characterized by a large swing angle, but it is heavy and inconvenient to move, so it is not suitable for flexible firefighting needs.
