Description

Technical Field

[0001] The utility model relates to the field of fire protection, and more specifically, to a smoke exhaust device for fire protection. Background Art

[0002] Firefighting means eliminating hidden dangers and preventing disasters. Its narrow meaning in the early stage of people's understanding is: putting out the fire. Usually when a fire just occurs, a large amount of thick smoke will be produced, which will hinder people from escaping from the fire scene. Existing smoke exhaust devices usually discharge the thick smoke directly into the atmosphere, and the smoke exhaust speed is slow. A large amount of thick smoke will reduce the firefighters' sight. In addition, there are a large amount of toxic gases and toxic particles in the thick smoke produced by the burning flame. Directly discharging it into the atmosphere will cause a lot of pollution to the atmosphere. In addition, the installation steps of the existing smoke exhaust device are very cumbersome, which brings great trouble to the installers and is not convenient for disassembly and cleaning.

[0003] The utility model with authorization announcement number CN213713385U relates to the field of fire fighting technology, and discloses a smoke exhaust device for fire fighting, including a smoke exhaust box, the bottom of the inner wall of the smoke exhaust box is fixedly connected to the bottom of the motor through a fixed block, one end of the motor is fixedly connected to one end of a rotating rod, the other end of the rotating rod is fixedly connected to one side of a bevel gear, the bevel gear is meshed with the bevel gear, the bottom of the bevel gear is fixedly connected to one end of the rotating rod, the outer surface of the middle part of the rotating rod is fixedly connected to the inner ring of the bearing, and the outer ring of the bearing is fixedly connected to one end of the fixed rod. The smoke exhaust device for fire fighting drives the rotating rod to rotate through the motor, so that the bevel gear drives the bevel gear to rotate, drives the rotating rod to rotate, and drives the exhaust fan to rotate, quickly sucking the thick smoke generated by the burning flame into the smoke pipe, achieving a faster smoke exhaust speed, preventing a large amount of thick smoke from reducing the sight of the firefighters, and solving the problem that the smoke exhaust speed is slow and a large amount of thick smoke will reduce the sight of the firefighters.

[0004] In the above disclosed structure, a single spraying method is used to treat the flue gas, and the flue gas cannot be directly passed into water for purification. It has poor adaptability and cannot be installed and adjusted separately, which affects the smoke exhaust efficiency. In addition, the complex structure is not conducive to combined installation and needs to be improved. Utility Model Content
