Description

Technical Field

[0001] The present invention belongs to the technical field of tunnel ventilation equipment, and in particular relates to a tunnel ventilation device with a drainage function. Background Art

[0002] Tunnels are relatively enclosed spaces, and their internal air quality is directly related to driving safety, equipment lifespan, and personnel health. Motor vehicles operating in tunnels emit harmful gases such as carbon monoxide and nitrogen oxides. Furthermore, the heat and dust generated by vehicle travel, as well as the humid environment within the tunnel, can lead to equipment corrosion and reduced visibility. The core goal of tunnel ventilation systems is to continuously replace fresh air, dilute pollutant concentrations, and regulate temperature and humidity to ensure safe tunnel operation. Currently, tunnel ventilation primarily relies on a combination of natural and mechanical ventilation, leveraging pressure differences caused by temperature differences inside and outside the tunnel, elevation differences at the tunnel entrance, and piston wind generated by trains passing through to drive air flow. When there is an altitude difference between the two ends of a tunnel, air flows from high-pressure areas to low-pressure areas. When trains travel at high speeds, the piston effect forces polluted air out of the tunnel. This method is suitable for short tunnels, offering advantages such as energy savings and minimal equipment maintenance. However, it is significantly affected by climate and topography, and wind flow direction can be erratic. When natural ventilation is insufficient, mechanical ventilation equipment is used for active ventilation.

[0003] In existing technology, when a vehicle travels in a tunnel, compressed air at the front creates a high-pressure area, which diverts air to the sides. The rapid movement of the rear creates a low-pressure area, which draws air from behind to fill the area, forming a wake. This wake carries dust along with it, spreading in the direction of the vehicle's movement. Simultaneously, the vehicle's exhaust follows its movement, causing the dust and exhaust mixture to move forward and impact the blades of the ventilation equipment. This impact causes grooves to form on the blades, and the acidic substances in the exhaust further corrode the blades, shortening the fan's service life. Summary of the Invention

[0040] Specifically, when large vehicles enter the inside of tunnel main body 1, the body shape of large vehicles is larger, so that the air above the inside of tunnel main body 1 is rapidly flowed, at this time, the air driven by large vehicles impacts sliding plate 84, sliding plate 84 slides on sliding rod 83, and third spring 85 contracts at the same time, at the same time, driven rod 86 above sliding plate 84 moves along with sliding plate 84, driven rod 86 drives moving plate 9 to move, moving plate 9 moves and drives gear slot 91 to move, gear slot 91 drives fixed gear 93 to engage, and then take-up reel 92 rotates, take-up reel 92 rotates and tightens cable, cable pulls lifting plate 7, and lifting plate 7 descends, and return spring 71 elongates;

[0041] It should be noted that the fan inside exhaust fan 20 ventilates the inside of the tunnel, when large vehicles pass, the dust and exhaust gas rolled will impact the blades of the fan, so that the blades of the fan are damaged, affecting the normal use of the fan, at this time, the air flow driven by large vehicles will impact sliding plate 84, so that the air inside exhaust fan 20 passes through the inside of shell 22 and then enters spoiler pipe 24 through air outlet 23, spoiler pipe 24 is arranged in front of exhaust fan 20, so that when exhaust fan 20 works, the air sprayed by spoiler pipe 24 can blow the mixture of dust and exhaust gas to other positions, preventing the mixture from damaging the fan blades;

[0042] It should be noted that, according to the size of the vehicle, the speed of the air flow driven is different, so the distance of the sliding plate 84 moving is different, so that the device can automatically adapt to the different speed of the air flow driven by the vehicle, and the speed of the air flow ejected by the spoiler 24 is also changed, thereby realizing the self-adaptive function and improving the flexibility of the device.

[0046] Specifically, when the exhaust fan 20 is working, it drives the air flow, and then the rotation of the blade 34 drives the rotation of the rotating shaft 33, and the rotation of the rotating shaft 33 drives the rotation of the impact rod 35;

[0047] It should be noted that when the impact rod 35 rotates, it will contact the impact plate 44, so that the lifting rod 42 drives the sealing plate 45 to descend, and the first spring 43 reciprocates, through the above-mentioned mode, the external air enters the inside of the fixed pipe 4 through the air inlet hole 41, and then the air is pressed downward by the sealing plate 45, the air passes through the one-way valve 47, the air charging pipe 46, and finally enters the inside of the dust removal cavity 57 through the air inlet pipe 52 to be pressurized, so that the subsequent atomizing nozzle 65 sprays the atomized water, and the inside of the tunnel is dusted;

[0048] It should be noted that when the small vehicle passes, the vehicle drives the surrounding air to flow quickly, and the air impacts the trigger plate 63, and the trigger plate 63 rotates around the fixed shaft 61, at this time one end of the trigger plate 63 pulls the blocking plate 68 through the cable, the blocking plate 68 moves outward, the second spring 69 is elongated, the blocking plate 68 is separated from the sealing groove 67, so that the spraying pipe 64 is opened, the internal pressure of the dust removal cavity 57 is high, so that the water is quickly atomized through the atomizing nozzle 65, and the atomized water vapor converges to the tail of the vehicle along the air flow formed by the vehicle, so that the dust generated when the vehicle passes is reduced, and the water vapor can also neutralize part of the pollutants in the vehicle exhaust;

[0049] It should be noted that when the vehicle is driving, the front compressed air forms a high pressure area, and the air is divided to both sides; the tail of the vehicle forms a low pressure area due to rapid movement, and attracts the air behind to fill, forming a wake. This wake will wrap dust and spread in the direction of the vehicle, so that the front air flow of the vehicle drives the trigger plate 63 to rotate, and the water vapor is sprayed out and quickly moves to the tail end of the vehicle to dust the tail end of the vehicle and neutralize part of the pollutants in the exhaust gas.

[0050] Please refer to Figure 8 and Figure 9 , the drainage and dust removal assembly 5 comprises a fixed box 50 installed on the inner wall of both sides of the tunnel body 1, a collecting groove 51 is formed in the top of the fixed box 50, an air inlet pipe 52 is installed on the top of the fixed box 50, one end of the air inlet pipe 52 communicates with one end of the air charging pipe 46, a drive motor 53 is installed on the outer wall of the fixed box 50, the output end of the drive motor 53 extends into the inside of the fixed box 50, a pressing wheel 54 is installed on the output end of the drive motor 53, a driven wheel 55 is installed on the inner wall of the fixed box 50, and the driven wheel 55 is close to the pressing wheel 54, the pressing wheel 54 and the transmission wheel 12 are transmissionally connected through the cleaning belt 13, the inner wall of the fixed box 50 is separated into a waste water cavity 56 and a dust removal cavity 57 by a partition plate, the pressing wheel 54 and the driven wheel 55 are located in the inside of the waste water cavity 56, a water level sensor 58 is installed on the inner wall of the waste water cavity 56, and a drainage pump 59 is installed on the inner wall of the waste water cavity 56.

[0051] Specifically, after the moisture-absorbing cotton absorbs the moisture on the inner wall of the tunnel, the moisture-absorbing cotton enters the waste water cavity 56, the driving motor 53 rotates the extrusion wheel 54 and the cleaning belt 13, so that the moisture-absorbing cotton after absorbing water passes between the extrusion wheel 54 and the driven wheel 55, and is discharged by extrusion, thereby realizing the drainage function of the tunnel. When the sewage in the waste water cavity 56 reaches the water level sensor 58, the sewage in the waste water cavity 56 is discharged by the drainage pump 59, thereby realizing the drainage function.

[0052] The working principle is as follows: first, the fan inside the exhaust fan 20 ventilates the inside of the tunnel. When a large vehicle passes, the rolled-up dust and exhaust gas will rush to the blades of the fan, causing the blades of the fan to be damaged and affecting the normal use of the fan. At this time, the air flow driven by the large vehicle will impact the sliding plate 84, so that the air inside the exhaust fan 20 passes through the inside of the shell 22 and then enters the spoiler pipe 24 through the exhaust port 23. The spoiler pipe 24 is arranged in front of the exhaust fan 20, so that when the exhaust fan 20 is working, the air sprayed by the spoiler pipe 24 can blow the dust and exhaust gas mixture to other positions, preventing the mixture from damaging the fan blades. Then, when a small vehicle passes, the air around the vehicle flows rapidly, and the air impacts the trigger plate 63. The trigger plate 63 rotates around the fixed shaft 61. At this time, one end of the trigger plate 63 pulls the blocking plate 68 through the cable, the blocking plate 68 moves outward, the second spring 69 is elongated, the blocking plate 68 is separated from the sealing groove 67, so that the spraying pipe 64 is opened, the air pressure in the dust removal cavity 57 is high, so that the water is quickly atomized by the atomizing nozzle 65. The atomized water vapor converges to the rear of the vehicle along the air flow formed by the vehicle, thereby reducing the dust generated when the vehicle passes. The water vapor can also neutralize part of the pollutants in the vehicle exhaust. Finally, after the moisture-absorbing cotton absorbs the moisture on the inner wall of the tunnel, the moisture-absorbing cotton enters the waste water cavity 56, the driving motor 53 rotates the extrusion wheel 54 and the cleaning belt 13, so that the moisture-absorbing cotton after absorbing water passes between the extrusion wheel 54 and the driven wheel 55, and is discharged by extrusion, thereby realizing the drainage function of the tunnel. When the sewage in the waste water cavity 56 reaches the water level sensor 58, the sewage in the waste water cavity 56 is discharged by the drainage pump 59, thereby realizing the drainage function.
