Power-driven pneumatic extinguisher

Abstract

The invention discloses a power-driven pneumatic extinguisher, comprising a machine body capable of generating high speed airflow and an exhaust pipeline connected with the machine body, wherein the machine body comprises a shell, an electric drive system arranged in the shell, and a centrifugal fan which is driven by the electric drive system and generates the high speed airflow. The power-driven pneumatic extinguisher has the advantages of being good in controllability, simple in structure, energy-saving, environment-friendly, high in efficiency, safe, reliable and the like, and can be used for fire extinction and debris cleaning.

Description

technical field [0001] The invention relates to a wind fire extinguishing device, in particular to a rechargeable electric wind fire extinguisher in the field of new energy technology. Background technique [0002] At present, the existing wind-powered fire extinguishing devices usually use a fuel engine to drive a centrifugal fan fixedly connected to its output shaft to rotate at high speed. Creates a powerful high-speed air jet for extinguishing fires and clearing debris. [0003] Since the traditional wind fire extinguisher uses a fuel engine as the power component, the related fuel, fuel tank, carburetor, spark plug, manual oil pump, etc. must be equipped, which makes the traditional wind fire extinguisher not only complicated in structure and difficult to maintain, but also difficult to start ( It will even be difficult to start at low temperature), and it is not easy to operate, so it takes too long before it is put into work, or even cannot be put into use normally,...

Problems solved by technology

[0003] Since the traditional wind fire extinguisher uses a fuel engine as the power component, the related fuel, fuel tank, carburetor, spark plug, manual oil pump, etc. must be equipped, which makes the traditional wind fire extinguisher not only complicated in structure and difficult to maintain, but also difficult to start ( It will even be difficult to start at low temperature), and it is not easy to operate, so it takes too long before it is put into work, or even cannot be put into use normally, which is very likely to delay the timing of fire extinguishing and cause greater losses; in addition, because the fuel engine is used as a power component, in At the scene of a fire, the traditional wind fire extinguisher may spontaneously ignite and cause personal injury; in addition, when the fuel engine works as a power component, it is not only inefficient, but also produces strong vibration, noise and exhaust gas pollution. Traditional fire extinguishing device fire extinguishing costs increase
