The technical field is as follows:

the invention relates to the technical field of fire fighting, in particular to a rotary fire extinguisher.

Background art:

the grassland fire refers to a disaster caused by fire burning in grasslands, grasshills and grasslands due to natural or artificial reasons. Because of large grassland area, flat terrain and inflammable combustible materials, once a fire disaster happens, the grassland has the characteristics of high spreading speed, large fire field area, easy change, serious loss and the like.

As the grassland is generally rugged and the soil is soft, the traditional large fire truck and the water tank truck are difficult to enter the fire scene. At present, the fire disaster in the grassland generally adopts a manual fire extinguishing mode, and the fire is usually extinguished by a manual shoulder-back wind fire extinguisher or a hand-held shovel or a broom in a beating mode. Often, because of big wind power in the fire scene, the fire scene condition is complicated, has the shortcoming such as fire extinguishing efficiency is low, intensity of labour is big, personnel can be burnt at any time.

The invention content is as follows:

the invention aims to provide a rotary fire extinguisher which realizes fire extinguishing by realizing the beating action through machinery.

The invention is implemented by the following technical scheme: the rotary fire extinguisher comprises two telescopic arms, a fire baffle plate, a cantilever, a rotating shaft, a driving device, a bracket plate, a supporting rod and a fire extinguishing sheet; the fire baffle is vertically and fixedly arranged between the top ends of the telescopic rods of the two telescopic arms which are arranged in parallel; two parallel cantilevers are arranged on the fire baffle plate; the rotating shaft which is horizontally arranged is rotatably arranged between the top ends of the two cantilevers; the cantilever is provided with the driving device in transmission connection with the rotating shaft; the rotating shaft is fixedly provided with two bracket discs with the same shape, and each bracket disc consists of more than two bracket rods which are arranged along the radial direction of the rotating shaft; the bracket rods of the two bracket plates are correspondingly arranged in parallel, the supporting rod parallel to the rotating shaft is arranged between the bracket rods which are correspondingly parallel, and more than one fire extinguishing piece is arranged on the supporting rod in a rotating manner.

Preferably, the telescopic arm is a hydraulic cylinder; the top end of a piston rod of the hydraulic cylinder is provided with the fire baffle.

Preferably, the driving device is any one of a hydraulic motor and an electric motor.

Preferably, the fire extinguishing sheet is made of flexible fireproof materials.

Preferably, a fireproof cover is arranged at the top of the fireproof plate.

The invention has the advantages that: compared with the prior art, the mechanical mode is adopted to replace the traditional manual beating mode for fire extinguishing, the beating fire extinguishing range in the grassland fire extinguishing process is effectively enlarged, and the efficiency of the grassland fire extinguishing work is further improved while the beating dead angle generated in the fire extinguishing process is effectively prevented; the labor intensity of fire-fighting personnel is reduced, and the safety of the personnel is effectively protected; the physical way is adopted for extinguishing fire, which does not cause pollution to the grassland which is over fire and does not destroy the regenerated root system of the pasture.
