[0058] Preferably, the ventilation assembly 200 also includes a filter cartridge 206; the filter cartridge 206 is fixed on the ventilation pipe 203. During construction, there will be many dust particles floating in the air. The filter cartridge 206 is used to filter large dust particles in the air to prevent larger dust particles from entering the ventilation pipe 203 and causing the filter screen 101 to be blocked when the air is discharged from the exhaust pipe 207; there are multiple filter cartridges 206, and a filter cartridge 206 is fixed on each section of the ventilation pipe 203. The filter cartridge 206 connects the ventilation pipe 203 and the inside of the shaft, and the filter cartridges 206 are fixed on the ventilation pipe 203 in a uniform array.

[0059] Preferably, both ends of the air inlet pipe 201 and the exhaust pipe 207 are rotatably connected with the filter 101 respectively; the air inlet fan 302 and the exhaust fan 303 are driven by a double-headed motor, which can accelerate the air flow speed when ventilating the vertical shaft, thereby accelerating the air exchange between the inside of the vertical shaft and the outside, ensuring the air quality inside the vertical shaft, and leaving a gap between the fan blades of the air inlet fan 302 and the exhaust fan 303 and the filter 101; the filter 101 is rotatably connected to the air inlet cavity 202 and the exhaust cavity 204 at one end close to the ventilation pipe 203.

[0060] Preferably, openings are provided at the tops of the air inlet chamber 202 and the exhaust chamber 204, and the air inlet chamber 202 and the exhaust chamber 204 are connected to the water tank 102 through the openings, respectively. When the air humidity is low, the dust generated during the construction in the shaft will diffuse in the air. When the air humidity is high, the dust generated during the construction will be absorbed by the water droplets in the air. When the air humidity entering the air inlet chamber 202 or the exhaust chamber 204 is low, water is sprayed into the air inlet chamber 202 or the exhaust chamber 204; the diameters of the air inlet chamber 202 and the exhaust chamber 204 are larger than the diameter of the ventilation pipe 203; the air inlet chamber 202 and the exhaust chamber 204 are rotatably connected to the ventilation pipe 203, respectively.

[0061] Preferably, a scraper 107 is fixed on the blades of the exhaust fan 303, and the scraper 107 is located inside the exhaust chamber 204; when the air in the shaft is discharged through the exhaust pipe 207, there will be many dust particles mixed in the air, and these dust particles will adhere to the filter 101.

[0062] Preferably, the ventilation pipes 203 are fixedly connected by connecting pipes 108; the connecting pipes 108 are rotatably connected to the ventilation pipes 203 by threads; the ventilation pipes 203 are multiple cylindrical pipes, and the ventilation pipes 203 extend into the interior of the vertical shaft.

[0063] Preferably, a support frame 109 is fixed in the ventilation pipe 203, and a ventilation fan 305 is fixed on the support frame 109; the ventilation fan 305 is used to drive the air to flow in the ventilation pipe 203 under the control of the central processor 301; there are multiple ventilation fans 305, and a ventilation fan 305 is respectively fixed in each section of the ventilation pipe 203. The ventilation fan 305 can speed up the flow of air in the ventilation pipe 203. When there is a lot of dust generated by the construction in the shaft or the air quality in the shaft is poor, the ventilation fan 305 is operated to speed up the air flow rate, thereby quickly restoring the air quality in the shaft.

[0064] Preferably, an opening connected to the storage box 103 is opened at the bottom of the exhaust cavity 204, and the storage cavity is used to store dust cleaned from the filter screen 101.

[0065] Preferably, a circular hole is opened on the side wall of the ventilation duct 203; a humidity sensor 307 is fixed in the circular hole on the side wall of the ventilation duct 203, and the humidity sensor 307 can detect the humidity in the ventilation duct 203. The central processing unit 301 can control the operating speeds of the intake fan 302 and the exhaust fan 303 according to the detection of the humidity sensor 307. When the humidity is low, the intake fan 302 can be controlled to accelerate to allow more humid air to enter the ventilation duct 203. When the air humidity is high, the operating speed of the intake fan 302 can be controlled to decrease.

[0066] Preferably, a water inlet 104 is connected to the top of the storage box 103, and the water inlet 104 is used to add water to the storage box 103; the air inlet pipe 201 and the exhaust pipe 207 are parallel to each other, and the air inlet pipe 201 and the exhaust pipe 207 are fixed at the mouth of the shaft.

The ventilation pipe 203 is attached to the side wall of the shaft and extends to the bottom of the shaft. The ventilation pipe 203 is connected by an elastic hose at the bottom of the shaft to connect the air inlet pipe 201 and the exhaust pipe 207.

[0067] In actual use, a shaft intelligent ventilation system according to an embodiment of the present application:

[0068] First, the humidity sensor 306 detects the humidity of the air entering the air intake pipe 201 and transmits the detection signal to the central processor 301. When construction is carried out in the shaft, the central processor 301 sends a signal to control the operation of the air intake fan 302 and the exhaust fan 303. The nozzle 205 connected to the air intake chamber 202 is driven by the driving pump 304 to operate, so that the air entering the ventilation pipe 203 remains moist. At the same time, the humidity sensor 306 can detect the humidity of the air discharged from the exhaust pipe 207. When the air is relatively dry, the nozzle 205 leading to the exhaust chamber 204 is driven by the driving pump 304 to operate the dust discharged from the exhaust pipe 207 to adhere to the water droplets, so as to prevent the dust generated during construction from being discharged into the air. Each section of the ventilation pipe 203 can control the air circulation speed by the ventilation fan 305 according to the signal detected by the humidity sensor 306, thereby ensuring that the dust generated during construction can be discharged in time.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
