Fire-fighting smoke exhaust fan capable of achieving multi-angle adjustment and independent control

Abstract

The invention relates to the technical field of smoke exhaust fans, and discloses a fire-fighting smoke exhaust fan capable of achieving multi-angle adjustment and independent control. The fire-fighting smoke exhaust fan capable of achieving multi-angle adjustment and independent control comprises a machine body, six sets of air outlet devices distributed in an annular array are arranged on the output end face of the right side of the machine body, the air outlet devices comprise first air ducts, second air ducts, third air ducts and fourth air ducts, the six sets of first air ducts are fixedly installed on the output end face of the right side of the first air ducts in an annular array mode. According to the fire-fighting smoke exhaust fan capable of achieving multi-angle adjustment and independent control, the air outlet devices are arranged, and the effect that the second air ducts, the third air ducts and the fourth air ducts are driven by output of respective servo motors is achieved, so that the second air ducts, the third air ducts and the fourth air ducts are matched with one another for use, and all the six sets of air outlet devices can blow air at multiple angles and inmultiple directions independently; and compared with single air outlet of a machine body in the prior art, the working efficiency of the machine body is improved, meanwhile, the fire-fighting smoke exhaust efficiency is improved, the height adjustment or angle adjustment does not need to be carried out on the output end of the machine body, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the technical field of smoke exhaust fans, in particular to a multi-angle adjustable and individually controlled fire smoke exhaust fan. Background technique [0002] As the name suggests, the fire smoke exhaust fan is used for fire smoke exhaust. It uses the fan to rotate and blow out the wind to exhaust the air, so as to achieve the effect of smoke exhaust. However, the wind power output end of the existing fire-fighting smoke exhaust machine is generally designed in a single way, which can only discharge air from a single outlet, and cannot achieve multi-angle, multi-direction and independent control of the effect of the size of the wind. When it comes to the smoke exhaust machine, the defects of the prior art are fully exposed, and it is impossible to simultaneously discharge air and smoke from multiple angles and directions. Therefore, the existing technology has certain defects and disadvantages in the actual use process....

However, the wind power output end of the existing fire-fighting smoke exhaust machine is generally designed in a single way, which can only discharge air from a single outlet, and cannot achieve multi-angle, multi-direction and independent control of the effect of the size of the wind. When it comes to the smoke exhaust machine, the defects of the existing technology are fully exposed, and it is impossible to realize simultaneous air and smoke exhaust from multiple angles and directions. Therefore, the existing technology has certain defects and disadvantages in the actual use process.
