Problems solved by technology

[0009] 1. Simply using air supply to exhaust smoke cannot effectively improve the visibility of the fire scene
[0010] 2. The water mist fire extinguishing device installed in a fixed field and using the pressure of the pipe network to provide fire extinguishing water has a fixed position and a limited range of action, so it cannot exert its due effect

Embodiment Construction

[0026] see figure 1 , the present embodiment takes the fire truck 1 as the carrier.

[0027] see figure 1 , figure 2 and image 3 , at the tail of the fire engine 1, a vehicle-mounted air duct 2 is arranged, and an axial flow fan 3 is arranged in the air duct 2. At the mouth of the air duct 2, an annular water channel 4 is arranged along the outer periphery of the air duct 2, and the inlet of the annular water channel 4 The water pipe mouth 6 is located on the outer wall of the air duct at the location of the annular water channel 4 .

[0028] figure 2 , image 3 and Figure 4 As shown, the fine water mist nozzles 5 are evenly distributed along the annular water channel 4 , and each fine water mist nozzle 5 is arranged obliquely, and the jet axis 7 of each obliquely arranged fine water mist nozzle 5 forms a cone shape in front of the air cylinder 2 .

[0029] In specific implementation:

[0030] Through calculation and test, when the water supply pressure provided by...

Abstract

The present invention relates to a fire-fighting vehicle mounted water mist fire-suppressing and smoke-removing equipment. It is characterized by that it uses the fire-fighting vehicle as carrier, on the fire-fighting vehicle an air barrel is set, in the air barrel interior an axial-flow blower is set; in the barrel mouth position of said air barrel, along the periphery of said air barrel a ring-shaped conduit is set, along said ring-shaped conduit uniformly distributed are water mist nozzles. Said invention integrates vehicle mounting, fire-fighting, ventilation, smoke-removing and dust-removing functions into one body, and can quickly eliminate smoke, lower temperature and remove dust.

Description

Technical field: [0001] The invention relates to a fire-extinguishing and smoke-exhausting device, more specifically a vehicle-mounted fire-extinguishing and smoke-exhausting device. Background technique: [0002] The use of air supply and smoke exhaust devices at the fire extinguishing site has the following functions: [0003] 1. The high-power positive pressure air supply on the fire site can change the burning direction of the flame, which is beneficial to protect flammable and explosive and key places and areas. [0004] 2. For fires in petroleum, chemical and other industries, it can effectively dilute toxic and harmful gases, and change the diffuse direction of toxic and harmful gases according to different locations. [0005] 3. In the fire scene of subways and tunnels, the fire can be divided into different areas, which is convenient for organizing the attack and cover retreat of firefighters. [0006] 4. Before and after the fire is extinguished, proper air suppl...
