Problems solved by technology
[0003] However, when a fire breaks out, a large amount of smoke and dust will be generated due to a fire, so removing the smoke through the fresh air system can reduce the concentration of the smoke and prevent a large amount of smoke from being inhaled by the user; but when the fresh air system is used , the pipe opens upward to facilitate the discharge of the gas generated by the fire. When the pipe is not in use, the pipe opens upward, which will cause some debris to enter the pipe, affecting the use of the device in an emergency

The invention discloses a novel fire-fighting smoke exhaust fresh air system. The novel fire-fighting smoke exhaust fresh air system comprises a mounting base, an air outlet mechanism, an air outlet pipe, a connecting pipe, a cleaning mechanism, a protection mechanism, an adjusting mechanism, a second motor, a first gear and a second gear. The novel fire-fighting smoke exhaust fresh air system hasthe beneficial effects that the second motor is sleeved with the first gear, the air outlet pipe is sleeved with the second gear, and the second gear is engaged with the first gear, so that the second motor drives the air outlet pipe sleeved with the second gear to rotate, the opening direction of the air outlet pipe is adjusted, the interior of a pipeline is protected, chippings are prevented from entering the pipeline. the fresh air system is convenient to maintain at ordinary times, and the device is also convenient to use during fire protection and smoke exhausting; the air inlet pipe isrotationally connected to the mounting base, the air inlet pipe is conveniently supported and mounted through the mounting base, and operation of the device is facilitated; and the protection mechanism is mounted on the air outlet pipe, so that the device can be conveniently used in rainy days.
Description
technical field [0001] The invention relates to a fresh air system, in particular to a novel smoke exhaust fresh air system for fire fighting, which belongs to the technical field of fire fighting. Background technique [0002] Fresh air is the air outside the building, or air that has not been circulated by the HVAC system before entering the building. The fresh air outlets of air-conditioning units, fresh air units and variable air volume air-conditioning units are directly connected to the external space of the building to introduce fresh air. The main function of the fresh air unit is to provide constant temperature and humidity air or fresh air to the air conditioning area. Fresh air unit control includes supply air temperature control, supply air relative humidity control, antifreeze control, carbon dioxide concentration control, and various interlock controls. [0003] However, when a fire breaks out, a large amount of smoke and dust will be generated due to a fire,...
