Description

Technical Field

[0001] This utility model relates to the field of ventilation technology for subway tunnels, and more specifically, to a ventilation device for subway tunnels. Background Technology

[0002] A subway tunnel ventilation system is a specialized airflow regulation device used inside subway tunnels. Its main function is to guide and control airflow through precise duct adjustment, ensuring that fresh air is evenly distributed to every corner of the tunnel while promptly expelling exhaust gases. This device is crucial for maintaining air quality and reducing pollutant accumulation within subway tunnels. Current subway tunnel ventilation technology primarily relies on exhaust fans to draw outside air into the tunnel. However, this process inevitably involves the intake of dust, posing a threat to air quality. Therefore, dust filters are typically installed inside the tunnel ducts to prevent dust from entering. However, after prolonged use, these filters accumulate a large amount of dust, and due to their location within the duct, disassembly and cleaning become extremely difficult. This not only renders the filters ineffective but may also obstruct airflow, reducing the efficiency of air intake into the tunnel. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 As shown, this utility model provides a subway tunnel ventilation device, including an air duct 1. The air duct 1 has a groove 10 inside. A dustproof net 13 is movably installed inside the groove 10. A connecting block 2 9 is fixedly installed at the bottom of the dustproof net 13. A connecting block 1 8 is fixedly installed at one end of the connecting block 2 9. The air duct 1 is fixedly installed at one end of the connecting block 1 8.

[0023] Both sides of the evolution box 1 have limit slots 11, and limit blocks 7 are movably installed inside the limit slots 11. A spring 12 is fixedly installed inside the evolution box 1.

[0024] After prolonged use, the staff disassembled and installed the dustproof net 13. By holding the dustproof net 13, the staff squeezed the spring 12 in the slide groove 10, causing the limiting block 7 to slowly disengage from the limiting groove 11. The dustproof net 13 was then slowly removed from the inside of the box 2, and a new dustproof net 13 was installed inside the evolution box 1. By holding the dustproof net 13 again, the staff moved it inside the slide groove 10, causing the connecting block 2 9 and connecting block 1 8 to move simultaneously to the outer surface of the evolution box 1. The dustproof net 13 squeezed the spring 12, causing the limiting block 7 at one end of connecting block 1 8 to slowly enter the limiting groove 11. The limiting groove 11 then fixed the limiting block 7, thus completing the disassembly and installation of the rotating shaft 3.

[0025] The dustproof net 13 needs to be disassembled and installed. The dustproof net 13 presses against the spring 12 in the slide groove 10, causing the limiting block 7 to slowly disengage from the limiting groove 11. The dustproof net 13 is then slowly removed from the inside of the box 2, and a new dustproof net 13 is installed inside the evolution box 1. By holding the dustproof net 13, it is moved within the slide groove 10, causing connecting block 2 9 and connecting block 1 8 to move simultaneously towards the outer surface of the evolution box 1. The dustproof net 13 then presses against the spring 12, causing the limiting block 7 at one end of connecting block 1 8 to slowly enter the limiting groove 11. The limiting groove 11 then presses against the limiting block 7. Compared to traditional air guiding devices, this air guiding device, through the cooperation between the spring 12 limiting groove 11 and the limiting block 7, facilitates the replacement of the dustproof net 13, enabling rapid replacement of the dustproof net 13 and significantly reducing maintenance time and costs. This design also lowers maintenance costs, avoiding the complex tools and cumbersome steps required for replacing traditional fixed dustproof nets. More importantly, it ensures that the dustproof net is always in optimal condition, thereby improving the reliability and stability of the subway tunnel air guiding device, reducing malfunctions and downtime caused by dustproof net issues, and providing strong support for the safe and stable operation of the subway system.

[0026] Among them, a rotating shaft 3 is fixedly installed on the top of the evolution box 1, a tooth 16 is fixedly installed on one end of the rotating shaft 3, and the tooth 16 is movably installed inside the box 2. A motor 14 is fixedly installed inside the box 2, and a tooth 17 is fixedly installed on the output end of the motor 14, and the tooth 17 and the tooth 16 are engaged.

[0027] A connecting column 15 is fixedly installed on the top of the tooth 16, and one end of the connecting column 15 completely penetrates the interior of the box 2. Pipes 21 are fixedly installed on the front and back of the evolution box 1. A support block 20 is fixedly installed inside the pipe 21. A fan 19 is fixedly installed on the top of the support block 20. A fan 18 is fixedly installed at the output end of the fan 19.

[0028] To ensure fresh air is evenly distributed throughout the subway tunnel, workers need to adjust the angle of pipe 21. First, a fan 19 is turned on inside pipe 21, which drives a fan 18 to rotate, drawing outside air into the tunnel. Then, a motor 14 is turned on inside housing 2, which drives tooth 17 to rotate. The teeth of tooth 17 and tooth 16 mesh, causing tooth 17 to rotate, which in turn drives tooth 16 to rotate. Tooth 16 then drives connecting column 15 and rotating shaft 3 to rotate simultaneously, which in turn drives air exchange box 1 to rotate, which in turn drives pipe 21 to rotate, thus completing the ventilation of the subway tunnel.

[0029] To ensure fresh air is evenly distributed throughout the subway tunnel, the angle of pipe 21 needs to be adjusted. First, a fan 19 is activated inside pipe 21, driving a fan 18 to rotate and draw outside air into the tunnel. Then, a motor 14 is activated inside housing 2, driving a toothed gear 17 to rotate. This gear 17 then drives a toothed gear 16, which in turn drives the connecting column 15 and the rotating shaft 3 to rotate simultaneously. The rotating shaft 3 then drives the air purification box 1 to rotate, which in turn drives pipe 21 to rotate. Compared with traditional air guiding devices, this air guiding device, through the cooperation between tooth 17 and tooth 16, facilitates the left and right adjustment of the duct 21 inside the subway tunnel, effectively guiding and controlling the airflow direction, ensuring uniform distribution of fresh air and timely discharge of exhaust gas, significantly improving ventilation efficiency, reducing humidity, temperature and concentration of harmful gases in the tunnel, and creating a more comfortable and safe environment for passengers and staff. At the same time, optimizing airflow also reduces unnecessary energy consumption, lowers the operating load of the fan 19, and achieves energy-saving goals. In emergency situations, the air guiding device can be quickly adjusted to guide airflow away from the danger zone, facilitating rescue efforts.

[0030] Among them, a fixing block 5 is fixedly installed on the front of the box 2, and a positioning hole 6 is opened inside the fixing block 5.

[0031] By holding the steel nail, slowly insert the steel nail into the positioning hole 6, and fix it by the steel nail fixing block 5 and the positioning hole 6. The cooperation between the positioning holes 6 and the positioning hole 6 makes it easy to fix the box 2 to the wall, thus improving the fixing efficiency of the box 2.

[0032] Among them, a support column 4 is movably installed between the top of the evolution box 1 and the bottom of the box body 2, and the support column 4 presents four identical shapes.

[0033] Since the four identical shapes of the support columns 4 are located on the top of the evolution box 1 and the top of the box 2, they facilitate the support of the box 2, ensuring the stability of the motor 14 inside the box 2, extending the service life of the motor 14, and improving the operating efficiency of the motor 14.

[0034] Among them, the limiting block 7 and the connecting block 1 8 are paired up, and there are two pairs at one end of the connecting block 2 9.

[0035] Since connecting block 18 and connecting block 29 are paired up, there are two sets at one end of connecting block 29. Through the cooperation between limiting block 7 and connecting block 18, the dustproof net 13 is fixed more stably, which improves the fixing efficiency of rotating shaft 3.

[0036] Among them, spring 12 has two identical shapes inside the evolution box 1, and spring 12 is made of stainless steel.

[0037] Because the spring 12 is made of stainless steel and has two identical shapes inside the evolution box 1, and the rotating shaft 3 is made of stainless steel with high strength, it can withstand a large load when the dustproof net 13 squeezes the spring 12. At the same time, it can provide stable elastic support for various forms of forces such as torsion, tension and compression, ensuring the stability and reliability of the spring in various application scenarios.

[0038] Working principle and usage process of this utility model:

[0039] After prolonged use, the staff disassembled and installed the dustproof net 13. By holding the dustproof net 13, the staff squeezed the spring 12 in the slide groove 10, causing the limiting block 7 to slowly disengage from the limiting groove 11. The dustproof net 13 was then slowly removed from the inside of the box 2, and a new dustproof net 13 was installed inside the evolution box 1. By holding the dustproof net 13 again, the staff moved it inside the slide groove 10, causing the connecting block 2 9 and connecting block 1 8 to move simultaneously to the outer surface of the evolution box 1. The dustproof net 13 squeezed the spring 12, causing the limiting block 7 at one end of connecting block 1 8 to slowly enter the limiting groove 11. The limiting groove 11 then fixed the limiting block 7, thus completing the disassembly and installation of the rotating shaft 3.

[0040] To ensure fresh air is evenly distributed throughout the subway tunnel, workers need to adjust the angle of pipe 21. First, a fan 19 is turned on inside pipe 21, which drives a fan 18 to rotate, drawing outside air into the tunnel. Then, a motor 14 is turned on inside housing 2, which drives tooth 17 to rotate. The teeth of tooth 17 and tooth 16 mesh, causing tooth 17 to rotate, which in turn drives tooth 16 to rotate. Tooth 16 then drives connecting column 15 and rotating shaft 3 to rotate simultaneously, which in turn drives air exchange box 1 to rotate, which in turn drives pipe 21 to rotate, thus completing the ventilation of the subway tunnel.
