Embodiment Construction

[0005] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0006] Such as figure 1 As shown, the wind fire extinguisher of the present embodiment includes three very light duct fans 5, air jet cylinder 7, movable connection 6, guard plate and handle 8, battery 2, electric adjustment 1, speed control switch 4, Wire 3. Working principle: Firefighters wear protective equipment, carry battery 2 and ESC 1 on their backs, lift the handle with one hand, and adjust the angles of the three air jet tubes with the other hand, aiming the upper one at the upper wind, the middle one at the waist wind, and the lower one Ground, and then turn on the speed control switch, three ducted fans work at the same time, spray violently, and quickly extinguish the fire. A firefighter using the wind fire extinguisher of this embodiment can support three firefighters who use a single nozzle wind fire extinguisher, because the ...

Abstract

The invention provides a pneumatic fire extinguisher. The pneumatic fire extinguisher comprises three light duct draught fans 5, airflow jet barrels 7, live connections 6, a guard plate and handle 8, a battery 2, an electronic speed controller 1, a speed control switch 4 and wires 3. The working principle of the pneumatic fire extinguisher is characterized in that a fireman puts on a protective device, carries the battery 2 and the electronic speed controller 1 on the back, holds the handle with one hand, and adjusts the angles of the three airflow jet barrels with the other hand, the upper airflow jet barrel is aligned with upstream wind, the middle airflow jet barrel is aligned with peripheral wind, and the lower airflow jet barrel is aligned with the ground; and the speed control switch is turned on, the three duct draught fans work simultaneously and violently jet to quickly extinguish fire. One fireman using the pneumatic fire extinguisher can replace three firemen using single-nozzle pneumatic fire extinguishers; and due to the fact that the firemen using the three single-nozzle pneumatic fire extinguishers need to cooperate, one single-nozzle pneumatic fire extinguisher is pressed towards the upstream wind, one single-nozzle pneumatic fire extinguisher is pressed towards the peripheral wind, and the remaining single-nozzle pneumatic fire extinguisher is aligned with the ground for fire extinguishment. The pneumatic fire extinguisher is small in weight, strong in wind power, and capable of replacing three single-nozzle pneumatic fire extinguishers and greatly improving efficiency of fire extinguishment.

Description

technical field [0001] The invention relates to the technical field of making a fire extinguisher, in particular to a wind-powered fire extinguisher. Background technique [0002] Existing a kind of patent No. is that 92106498.5 name is called " a kind of forest fire extinguisher " Chinese invention patent discloses a kind of forest fire extinguisher, and weight is bigger, can increase the portable burden of fireman, causes fireman's activity inconvenience, and fire extinguishing efficiency is low. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a light fire extinguisher with a reasonable and light structure, three ducted fans and three injection ports, high jet force and good fire extinguishing effect. The technical scheme adopted by the present invention to solve the above-mentioned technical problems is based on the wind fire extinguisher, which includes three ducted fans, air jet cylinder, movable connection,...
