TECHNICAL FIELD

[0001] The application relates to the technical field of underground garage smoke exhaust, and in particular to an underground garage vertical ventilation and smoke prevention and exhaust safety system. BACKGROUND

[0002] An underground garage is often in a semi-closed state, which makes it difficult for carbon monoxide, nitrogen oxides and other exhaust gases emitted by vehicles in the garage to diffuse. Therefore, an underground garage usually needs to be provided with a ventilation and smoke prevention system to exhaust the exhaust gases and reduce the concentration of harmful gases in the underground garage.

[0003] In the related art, a Chinese patent document with the publication number CN113983597A discloses an underground garage vertical ventilation and smoke prevention and exhaust safety system, which comprises a smoke prevention device arranged inside a safety passage and a smoke exhaust device arranged inside the garage. The smoke exhaust device comprises a first air treatment mechanism and a second air treatment mechanism arranged in sequence in the vertical direction. The smoke exhaust device further comprises a smoke exhaust duct arranged on one side of the first air treatment mechanism, a smoke exhaust fan arranged at the smoke exhaust end of the smoke exhaust duct, a first shell of the first air treatment mechanism, an upper smoke inlet arranged on one side of the first shell, an upper smoke inlet fan arranged at the upper smoke inlet, a treatment pool arranged inside the first shell, and a connecting pipe connecting the upper smoke inlet and the treatment pool. The treatment pool is filled with a treatment dissolving solution, which can be a sodium hydroxide solution, a calcium hydroxide solution, etc. The outlet end of the connecting pipe is closed and a plurality of through holes are formed in the side wall thereof. The outlet end of the connecting pipe extends into the treatment pool. The side of the first shell, which is away from the upper smoke inlet, is in communication with the smoke exhaust duct.

[0045] The implementation principle of the embodiment of the present application is as follows: when the smoke exhaust work is performed, the first filter plate 11 is located at the first magnet 19 between the input pipe 5 and the through hole 4. The second filter plate 13 is leveled with the first filter plate 11 under the action of the transmission member 16. Under the adsorption action of the first magnet 19, the second magnet 20 drives the first adjusting plate 17 to move towards the direction close to the first magnet 19, so that the second magnet 20 is adsorbed and matched with the first magnet 19. At this time, the first adjusting hole 18 is aligned with the corresponding first filter hole 12, and the first filter hole 12 is in an open state. The fourth magnet 25 and the fifth magnet 26 are in a disengaged state. The second spring 27 drives the second adjusting plate 23 to slide towards the direction away from the fourth magnet 25, so that the second adjusting hole 24 is aligned with the corresponding second filter hole 14, and the opening of the second filter hole 14 is realized. At this time, the water level of the treatment solution is located below the first filter plate 11 and above the through hole 4. The pH sensor 9 collects the pH value of the treatment solution and sends it to the controller 10. The controller 10 receives the pH value of the treatment solution and compares it with the preset value.

[0046] When the pH value of the treatment solution is lower than the preset value, it proves that the treatment solution does not meet the requirement of the pH value after long-term use. The controller 10 controls the second electromagnetic valve 8 to open, so that the treatment solution that does not meet the requirement in the treatment tank 2 is discharged from the treatment tank 2. At this time, the motor 153 is started, the motor 153 drives the screw rod 151 to rotate, the screw rod 151 drives the threaded sleeve 152 to move downwards, the second filter plate 13 is synchronously moved through the adsorption matching between the sixth magnet 161 and the seventh magnet 162, then the first magnet 19 and the second magnet 20 are disengaged, the first spring 22 in tension drives the first adjusting plate 17 to slide towards the direction away from the first magnet 19, the first adjusting hole 18 is misaligned with the corresponding first filter hole 12, so that the first filter hole 12 is closed. At this time, the fourth magnet 25 is close to the connecting pipe 3, the fourth magnet 25 adsorbs the fifth magnet 26 to drive the second adjusting plate 23 to slide towards the direction close to the fourth magnet 25, so that the second adjusting hole 24 is misaligned with the corresponding second filter hole 14, and the second filter hole 14 is closed.

[0047] Then the first electromagnetic valve 7 is opened, the clean treatment solution from the input pipe 5 enters the first filter plate 11 above the treatment tank 2, as the unsatisfactory treatment solution is discharged and the first filter plate 11 is lowered, the first filter plate 11 is gradually located below the through hole 4, so that the exhaust gas entering the connecting pipe 3 can be purified by the clean treatment solution above the first filter plate 11 and then discharged, until the unsatisfactory treatment solution is completely discharged from the treatment tank 2, and the first filter plate 11 is completely located below all through holes 4, at this time the first filter plate 11 moves to the third magnet 21, then the second electromagnetic valve 8 is closed, the third magnet 21 attracts the second magnet 20 to slide towards the third magnet 21, so that the first filter hole 12 is opened, the fourth magnet 25 is separated from the fifth magnet 26, the second filter hole 14 is opened by sliding the second adjusting plate 23 driven by the second spring 27, then the motor 153 is started in reverse, the screw rod 151 rotates to drive the threaded sleeve 152 to move the first filter plate 11 upwards for resetting, the second magnet 20 drives the third magnet 21 to move upwards, so that the first filter hole 12 and the second filter hole 14 remain open, until the first filter plate 11 moves to the first magnet 19 between the input pipe 5 and the through hole 4, at this time the second magnet 20 is separated from the third magnet 21, the third spring 36 drives the third magnet 21 to reset, after the treatment solution in the treatment tank 2 reaches the required amount, the first electromagnetic valve 7 is closed, so as to realize the timely replacement of the treatment solution, which helps to ensure the purification of the exhaust gas during the replacement process and is not easy to cause secondary pollution to the environment.
