Description

Technical Field

[0001] This invention relates to the field of subway platform screen door technology, specifically a novel particulate-proof, energy-saving, adjustable-vent subway platform screen door. Background Technology

[0002] The platform screen doors currently in use in domestic subways are divided into two types: one with air vents and the other without air vents.

[0003] The "Air Purification System Applicable to Subway Platform Levels" disclosed in application number "CN210345770U" is an increasingly mature technology. It "includes a fresh air system and an exhaust system. The fresh air system includes a fresh air fan, fresh air duct, platform air outlet, air quality detector, and lead wires. The exhaust system includes an exhaust fan, upper hot air duct, rail top hot air vent, lower hot air duct, rail bottom hot air vent, and platform exhaust outlet." This utility model addresses the current situation of excessive inhalable particulate matter in subway platform levels by providing an air purification system suitable for subway platform levels. This utility model can provide 5-30 m³ / s of fresh air to the platform level according to the size of the subway and the air quality conditions of the platform. Utilizing a top-to-bottom airflow organization, it isolates particulate matter from the track area generated by wheel-rail friction and vehicle operation. Simultaneously, using the rail top and rail bottom hot air vents, particulate matter in the track area is discharged into the exhaust shaft by the exhaust fan, protecting the health of personnel.

[0004] Traditional platform screen doors without vents have both advantages and disadvantages compared to those with vents. Without vents, they better isolate the tunnel from the subway station, preventing the transfer of cool air from the station into the tunnel during summer, thus reducing the energy consumption of the station's air conditioning. Simultaneously, they reduce the dispersion of particulate matter from the tunnel into the station, protecting the health of passengers and subway staff. Studies show that particulate matter in tunnels contains a large number of metal particles due to rail friction and arc discharge, and its toxicity is eight times higher than that of particulate matter from surface traffic. While platform screen doors without vents can reduce the use of air conditioning in the subway station during summer and isolate particulate matter from the tunnel, they cannot utilize piston-like airflow to cool the station during transitional seasons and winter. Furthermore, the use of platform screen doors leads to higher temperatures inside the tunnel in summer, inevitably increasing the energy consumption of tunnel ventilation fans and train air conditioning, thereby increasing the subway company's operating costs. Reducing energy consumption and saving operating costs without ensuring the health and comfort of passengers and staff is a problem that subway environmental control systems must consider.

[0005] Platform screen doors with vents can reduce the energy consumption of tunnel fans during transitional seasons and winter by utilizing piston-like airflow. However, this also increases the chance of particulate matter entering the subway station with the airflow, posing a health threat to waiting passengers and staff. Furthermore, the angle of currently used platform screen doors with vents is fixed and cannot be adjusted. Summary of the Invention

[0006] This invention aims to solve the problem of controlling heavy metal particles in subway stations and the problem that existing screen doors with vents cannot effectively utilize piston air by adjusting their angle, thereby reducing energy consumption in subway stations and reducing the risk of passengers inhaling harmful particles in the station.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a novel energy-saving adjustable vent subway platform screen door for preventing particulate matter, comprising a subway platform, wherein several left-side perforated screen doors and right-side perforated screen doors are fixedly installed on both sides of the subway platform, and a rotating mechanism is movably connected to one side of each of the left-side and right-side perforated screen doors, and a rotating baffle is provided on one side of the rotating mechanism. An automatic control system is fixedly connected to one side of one of the left-side perforated screen doors, and a left tunnel and a right tunnel are correspondingly provided on one side of each of the left-side and right-side perforated screen doors. Filter screens are provided inside the left-side and right-side perforated screen doors, and screen door holes are provided at corresponding positions of the left-side and right-side perforated screen doors. Left tunnel trains and right tunnel trains are provided inside the left-side and right-side tunnels, and control lines are provided at the bottom of each of the left-side and right-side perforated screen doors.

[0008] Preferably, the rotating mechanism includes a fixed column fixedly connected to the top of the left and right perforated shielding doors, a first worm gear fixedly connected to one end of the fixed column, a worm wheel meshing with the bottom end of the first worm gear, a main conical tooth fixedly connected to one end of the first worm gear, a secondary conical tooth meshing with one side of the main conical tooth, a rotating shaft fixedly connected to the middle of the secondary conical tooth, a small drive motor fixedly connected to the top of the rotating shaft, and a rotating baffle fixedly connected to the bottom end of the rotating shaft.

[0009] Preferably, the automatic control system includes a fixed plate, a wireless signal receiver is fixedly connected to the top of the fixed plate, a wireless signal transmitter is provided on one side of the wireless signal receiver, a signal data processing module is provided on one side of the wireless signal transmitter, a sensing control module is provided on one side of the signal data processing module, a drive control module is provided on one side of the sensing control module, and a controller is provided on one side of the drive control module.

[0010] Preferably, the wireless signal receiver, wireless signal transmitter, signal data processing module, sensing control module, drive control module, and small drive motor are all electrically connected to an external power supply through a controller.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] This invention provides a novel energy-saving adjustable air vent subway platform screen door that prevents particulate matter pollution:

[0013] 1. The perforated platform screen doors on the left and right sides are ordinary perforated platform screen doors. The subway station platform screen doors have openings at the top, and the rotating baffles are composed of ordinary louvered baffles, which serve to block airflow and particulate matter. The automatic control system can control the opening angle of the rotating baffles through the control circuit. The filter screen is composed of PM2.5 filtering devices, which serve to filter particulate matter in the tunnel, while allowing the filtered airflow to pass through.

[0014] 2. The automatic control system adjusts the angle of the rotating baffle through the control circuit to close the openings on both sides of the platform screen door. On the one hand, the filter screen will filter out coarse particles, and on the other hand, the platform screen door will block fine particles such as PM2.5, thereby reducing the dispersion of particulate matter from the tunnel into the platform. In summer, due to the closure of the openings of the platform screen door, the loss of cool air from the platform into the tunnel is reduced, saving energy.

[0015] 3. During the transitional season, when a train departs from the right-hand tunnel, the automatic control system adjusts the angle of the rotating baffle via the control lines, closing the opening on the left-hand platform screen door while keeping the opening on the right-hand platform screen door open. As the train departs, the pressure inside the right-hand tunnel is negative compared to the subway platform. The train creates a suction effect, drawing fluid from the platform into the tunnel through the opening on the right-hand platform screen door. Simultaneously, air from the subway concourse replenishes the platform, and air from the subway entrances enters the concourse and then flows into the platform. This eliminates the need for air conditioning to cool the subway station, thus saving energy.

[0016] 4. Platform screen doors with vents can reduce the energy consumption of tunnel fans by using piston air during transitional seasons and winter. However, this also increases the chance of particulate matter entering the subway station with the airflow, posing a health threat to waiting passengers and staff. In addition, the angle of the platform screen doors without vents currently in use can be adjusted to ensure the cleanliness of the subway station. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] like Figures 1-9 As shown, the present invention proposes a novel energy-saving adjustable vent subway platform screen door for preventing particulate matter pollution. It includes a subway platform 1, with several perforated left-side screen doors 2 and perforated right-side screen doors 10 fixedly installed on both sides of the platform 1. A rotating mechanism 4 is movably connected to one side of each perforated left-side screen door 2 and perforated right-side screen door 10. A rotating baffle 401 is provided on one side of each perforated left-side screen door 2. An automatic control system 3 is fixedly connected to one side of each perforated left-side screen door 2 and perforated right-side screen door 10. A left tunnel 7 and a right tunnel 12 are correspondingly provided on one side of each perforated left-side screen door 2 and perforated right-side screen door 10. A filter screen 6 is provided inside each of the left tunnel 7 and right tunnel 12. Screen door holes 8 are provided at corresponding positions on each of the perforated left-side screen doors 2 and perforated right-side screen doors 10. A left tunnel train 5 and a right tunnel train 11 are provided inside each of the left tunnel 7 and right tunnel 12. A control line 9 is provided at the bottom of each perforated left-side screen door 2 and perforated right-side screen door 10.

[0032] The perforated platform screen door 2 on the left and the perforated platform screen door 10 on the right are ordinary perforated platform screen doors, specifically, they have openings on the platform screen doors of the subway station. The rotating baffle 401 is composed of ordinary louvered baffles, which serve to block airflow and particulate matter. The automatic control system 3 can control the opening angle of the rotating baffle 401 through the control line 9. The filter screen 6 is composed of a PM2.5 filtering device, which serves to filter particulate matter in the tunnel, while allowing the filtered airflow to pass through.

[0033] The operation of this plan will be explained below in two scenarios: subway arrivals in summer and subway departures during the transitional season.

[0034] like Figure 2 As shown, due to the friction between subway wheels and rails, the subway tunnel is filled with a large amount of particulate matter. When the train 5 in the left tunnel enters the station, the automatic control system 3 adjusts the angle of the rotating baffle 401 through the control line 9 to close the openings on both sides of the platform screen doors. On the one hand, the filter screen 6 filters out coarse particles, and on the other hand, the platform screen doors block fine particles such as PM2.5, thereby reducing the dispersion of particulate matter from the tunnel into the platform. In summer, the closure of the platform screen door openings 8 reduces the loss of cool air from the platform into the tunnel, saving energy.

[0035] like Figure 3 As shown, during the transitional season, when train 11 in the right tunnel departs, the automatic control system 3 adjusts the angle of the rotating baffle 401 via control line 9, closing the opening on the left platform screen door while keeping the opening on the right platform screen door open. When train 11 in the right tunnel departs, the pressure inside the right tunnel 12 is negative compared to the subway platform 1, causing the train to create a suction effect. Fluid in the platform will enter the tunnel through the opening on the right perforated platform screen door 10. Simultaneously, air from the subway concourse will replenish the platform, and air from the subway entrances and exits will enter the concourse and then the platform. This allows for cooling of the subway station without the need for air conditioning, thus saving energy.

[0036] The rotating mechanism 4 includes a fixed post 402 fixedly connected to the top of the left perforated shielding door 2 and the right perforated shielding door 10. A first worm gear 403 is fixedly connected to one end of the fixed post 402. A worm wheel 404 is meshed with the bottom end of the first worm gear 403. A main bevel tooth 405 is fixedly connected to one end of the first worm gear 403. A secondary bevel tooth 406 is meshed with one side of the main bevel tooth 405. A rotating shaft 407 is fixedly connected to the middle of the secondary bevel tooth 406. A small drive motor 408 is fixedly connected to the top of the rotating shaft 407. The bottom end of the rotating shaft 407 is fixedly connected to the rotating baffle 401.

[0037] In practical use, when adjusting the angle of the rotating baffle 401, the rotation of the small drive motor 408 drives the rotating shaft 407 to rotate. The rotation of the rotating shaft 407 facilitates the rotation of the bevel gear 406. At the same time, in order to control the angle of the rotating baffle 409, the rotation of the worm gear 404 meshes with the first worm 403 to rotate. During the rotation of the first worm 403, the main bevel gear 405 is controlled to rotate and the speed of the bevel gear 406 is controlled, thus making it easier to control the opening and closing angle of the rotating baffle 401.

[0038] The automatic control system 3 includes a fixed plate 301. A wireless signal receiver 302 is fixedly connected to the top of the fixed plate 301. A wireless signal transmitter 303 is provided on one side of the wireless signal receiver 302. A signal data processing module 304 is provided on one side of the wireless signal transmitter 303. A sensing control module 305 is provided on one side of the signal data processing module 304. A drive control module 306 is provided on one side of the sensing control module 305. A controller 307 is provided on one side of the drive control module 306.

[0039] In practical use, when treating pollutants arriving at subway stations and departing during transitional seasons, the wireless signal receiver 302 and wireless signal transmitter 303 work together to analyze the arrival and departure signals of trains 2 and 11 in the left tunnel 7 and right tunnel 12, respectively. This facilitates the transmission and reception of these signals, enabling control and regulation of pollutant treatment during arrival and departure. The signal data processing module 304 and sensing control module 305 detect and analyze particulate matter in the airflow, and then the copper drum automatically controls the process. System 3 can control the opening angle of the rotating baffle 401 via control line 9. The filter screen 6 is composed of a PM2.5 filtering device, which filters particulate matter in the tunnel and allows filtered airflow to pass through. At the same time, the amount of PM2.5 filtered emissions is acquired by the sensing control module 305, and the opening and closing of the rotating baffle 401 is controlled. The opening and closing of the rotating baffle 401 will replenish the air in the subway station hall to the platform. The air from the subway entrance will enter the hall and then enter the platform. The subway station can be cooled without the need to turn on the air conditioner, thus saving energy.

[0040] The wireless signal receiver 302, wireless signal transmitter 303, signal data processing module 304, sensing control module 305, drive control module 306, and small drive motor 408 are all electrically connected to an external power supply through controller 307.
