Problems solved by technology

[0002] The fire extinguishing nozzle of the current wind fire extinguisher can only be used for wind fire extinguishing. This fire extinguishing method can only extinguish fire in a small area, and the fire extinguishing effect is relatively poor. When the wind speed is low, it cannot play the role of fire extinguishing.

Abstract

The invention discloses a multi-function fire-fighting air duct with wind power, spraying and foam fire-fighting functions. When atomization fire fighting is required, the water source in a chamber (6) is sprayed and dispersed out through the spraying of a plurality of nozzles (9) and the air power function of an air duct body (1), and the dispersed and sprayed water can be further refined to mistthrough the collision of an impeller (10); and when foam spraying for firefighting is needed, the impeller (10) is removed, the water source is induced into the chamber (6), meanwhile, air exhaust isconducted from an air outlet in a fan volute and the air outlet end (4) of the air duct body (1), the water source containing a foam agent in the chamber (6) is sprayed and dispersed out through thespraying of the nozzles (9) and the air power function of the air duct body (1), and the dispersed and sprayed water source passes through a filter net (12) and then form foam spraying for firefighting.

Description

technical field [0001] The invention relates to a multifunctional fire-extinguishing air duct with wind, spray and foam fire-extinguishing. Background technique [0002] The fire-extinguishing nozzle of the current wind-powered fire extinguisher can only be used for wind-powered fire-extinguishing. This fire-extinguishing method can only be used for fire-extinguishing in a small area, and the fire-extinguishing effect is relatively poor. When the wind speed is low, the fire-extinguishing effect cannot be achieved. SUMMARY OF THE INVENTION [0003] The invention provides a multifunctional fire-extinguishing air duct with wind power, spray and foam fire extinguishing, which can effectively combine wind power, spray and foam, so that a device in fire-fighting operation can use wind power to extinguish fire, or can The use of spray and foam to extinguish fire greatly improves the fire extinguishing effect and convenience. [0004] The invention adopts the following technical ...
