Description

Technical Field

[0001] The present invention relates to the technical field of subway platform screen doors, and particularly to a new type of particulate matter-proof, energy-saving and adjustable air outlet subway platform screen door. Background Art

[0002] The existing domestic subway platform screen doors in use are divided into two types. One is the screen door with air outlets, and the other is the screen door without air outlets.

[0003] Among them, the "Air purification system applicable to subway platform layer" disclosed in the patent application No. "CN210345770U" is also a technology that is becoming increasingly mature. It "comprises a fresh air system and an exhaust air system. The fresh air system includes a fresh air fan, a fresh air pipe, a platform air supply outlet, an air quality detector, and a lead wire. The exhaust air system includes an exhaust fan, an upper exhaust hot air duct, a rail top exhaust hot air hole, a lower exhaust hot air duct, a rail bottom exhaust hot air hole, and a platform exhaust air outlet. In view of the current situation of excessive inhalable particulate matter in the subway platform layer, the present invention provides an air purification system applicable to the subway platform layer. The present invention can provide 5-30 m3 / s of fresh air for the platform layer according to the size of the subway scale and the air quality condition of the platform layer, and use the air flow organization from top to bottom to isolate the particulate matter generated by the friction between the wheels and the rails and the vehicle operation in the track area. At the same time, by using the rail top exhaust hot air hole and the rail bottom exhaust hot air hole, the particulate matter in the track area is discharged to the exhaust air shaft through the exhaust fan to protect the health of personnel.

[0004] The traditional screen door without air outlets has both advantages and disadvantages compared with the screen door with air outlets. The screen door without air outlets can better isolate the tunnel from the subway station, avoiding the transmission of cold air in the subway station to the tunnel in summer and reducing the energy consumption of the air conditioner in the subway station in summer. At the same time, the screen door without air outlets can reduce the dispersion of particulate matter in the tunnel into the subway station and protect the health of passengers and subway staff. Research shows that the particulate matter in the tunnel contains a large amount of metal particles due to reasons such as rail friction and arc discharge, and its toxicity is 8 times higher than that of particulate matter in surface transportation in terms of carcinogenicity. Although the use of the screen door without air outlets can reduce the use of air conditioners in the subway station in summer and isolate the particulate matter in the tunnel, it cannot use the piston wind to cool the subway station in the transitional season and winter. At the same time, the use of the screen door makes the temperature in the tunnel higher in summer, which will inevitably increase the ventilation energy consumption of the tunnel fan and the energy consumption of the train air conditioner, and further increase the operating cost of the subway company. It is a problem that must be considered in the subway environmental control system to reduce energy consumption and save operating costs without ensuring the health and comfort of passengers and staff.

[0005] The platform screen door with air vents can reduce the energy consumption of tunnel fans in the transitional season and winter by utilizing piston air due to the presence of air vents. However, it will also increase the chance of particulate matter in the tunnel entering the subway station with the airflow, posing a health threat to waiting passengers and staff. Moreover, the angle of the currently used platform screen door with air vents is fixed and cannot be adjusted. Summary of the Invention

[0006] The present invention aims to solve the problem of controlling heavy metal particulate matter in subway stations and the problem that the existing platform screen door with air vents cannot adjust the angle to effectively utilize piston air, reduce the energy consumption of subway stations, and reduce the risk of passengers inhaling harmful particulate matter in the station.

[0007] To achieve the above object, the present invention provides the following technical solution: a new type of anti-particulate energy-saving adjustable air vent subway platform screen door, including a subway station platform. On both sides of the subway station platform, a number of left perforated screen doors and right perforated screen doors are fixedly installed respectively. One side of each left perforated screen door and right perforated screen door is movably connected with a rotating mechanism. One side of the rotating mechanism is provided with a rotating baffle. One side of one of the left perforated screen doors is fixedly connected with an automatic control system. The left tunnel and the right tunnel are correspondingly arranged on one side of the left perforated screen door and the right perforated screen door. A filter screen is arranged inside the left tunnel and the right tunnel. A screen door hole is arranged between the two corresponding left perforated screen doors and right perforated screen doors. A left tunnel train and a right tunnel train are arranged inside the left tunnel and the right tunnel. Control lines are arranged at the bottom of the left perforated screen door and the right perforated screen door.

[0008] Preferably, the rotating mechanism includes a fixed column fixedly connected to the top of the left perforated screen door and the right perforated screen door. One end of the fixed column is fixedly connected with a first worm. The bottom end of the first worm is meshed with a turbine. One end of the first worm is fixedly connected with a main conical gear. The main conical gear is meshed with a secondary conical gear on one side. A rotating shaft is fixedly connected to the middle of the secondary conical gear. A small driving motor is fixedly connected to the top of the rotating shaft. The bottom end of the rotating shaft is fixedly connected with the rotating baffle.

[0009] Preferably, the automatic control system includes a fixing plate. A wireless signal receiver is fixedly connected to the top of the fixing plate. A wireless signal transmitter is arranged on one side of the wireless signal receiver. A signal data processing module is arranged on one side of the wireless signal transmitter. An induction control module is arranged on one side of the signal data processing module. A driving control module is arranged on one side of the induction control module. A controller is arranged on one side of the driving control module.

[0010] Preferably, the wireless signal receiver, wireless signal transmitter, signal data processing module, induction 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] The present invention provides a new type of particulate matter-proof, energy-saving, and adjustable air vent subway platform screen door:

[0013] 1. The left perforated screen door and the right perforated screen door are ordinary perforated screen doors. There are openings at the upper part of the subway platform screen door. The rotating baffle is composed of ordinary louver baffles, which play a role in blocking air flow and particulate matter. The automatic control system can control the opening angle of the rotating baffle through control lines. The filter screen is composed of a PM2.5 prevention and filtration device, which plays a role in filtering particulate matter in the tunnel and allows the filtered air flow to pass through at the same time.

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

[0015] 3. In the transitional season, when a train leaves the station on the right side of the tunnel, the automatic control system adjusts the angle of the rotating baffle through control lines to close the opening on the left screen door, and the opening on the right screen door remains open. When a train leaves the station on the right side of the tunnel, the pressure in the right tunnel is negative compared to the subway platform. The train will generate a suction effect, and the fluid in the platform will enter the tunnel through the opening on the right screen door. At the same time, the air in the subway concourse will supplement the air in the platform, and the air at the subway entrance will enter the concourse and then enter the platform, cooling the subway station without turning on the air conditioner, thus playing a role in saving energy.

[0016] 4. The screen door with air vents can reduce the energy consumption of the fans in the tunnel in the transitional season and winter due to the piston wind, but at the same time, it will increase the chance of particulate matter in the tunnel entering the subway station with the air flow, posing a health threat to waiting passengers and staff. Moreover, the angle of the currently used non-air vent screen door can be adjusted to ensure the purification of the subway station. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "set" should be understood in a broad sense. For example, it can be fixedly connected and set, or detachably connected and set, or integrally connected and set. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] As Figures 1-9 shown, a novel particulate matter-proof, energy-saving and adjustable air outlet subway screen door proposed by the present invention includes a subway station platform 1. On both sides of the subway station platform 1, a number of left perforated screen doors 2 and right perforated screen doors 10 are fixedly installed respectively. On one side of each left perforated screen door 2 and right perforated screen door 10, a rotating mechanism 4 is movably connected. On one side of the rotating mechanism 4, a rotating baffle 401 is provided. On one side of one of the left perforated screen doors 2, an automatic control system 3 is fixedly connected. On one side of the left perforated screen door 2 and right perforated screen door 10, a left tunnel 7 and a right tunnel 12 are correspondingly provided. Inside the left tunnel 7 and right tunnel 12, a filter screen 6 is provided. Between the two corresponding left perforated screen doors 2 and right perforated screen doors 10, a screen door hole 8 is provided. Inside the left tunnel 7 and right tunnel 12, a left tunnel train 5 and a right tunnel train 11 are provided. At the bottom of the left perforated screen door 2 and right perforated screen door 10, a control line 9 is provided.

[0032] The left perforated screen door 2 and the right perforated screen door 10 are ordinary perforated screen doors. Specifically, openings are made in the subway station screen doors. The rotating baffle 401 is composed of ordinary louvre baffles, which play a role in blocking air flow 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 prevention filtering device, which plays a role in filtering particulate matter in the tunnel and at the same time allows the filtered air flow to pass through.

[0033] The operation of this solution will be explained separately in the following two situations: when the subway arrives at the station in summer and when the subway departs in the transitional season;

[0034] As Figure 2 shown, due to the friction between the subway wheels and the rails, a large amount of particulate matter will fill the subway tunnel. 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 screen door. On the one hand, the filter screen 6 will filter out coarse particulate matter, and on the other hand, the screen door will block fine particulate matter such as PM2.5, thereby reducing the dispersion of particulate matter in the tunnel into the platform. In summer, due to the closing of the holes 8 in the screen door, the loss of cold air in the platform into the tunnel is reduced, saving energy.

[0035] As Figure 3 shown, in the transitional season, when the train 11 in the right tunnel departs, the automatic control system 3 adjusts the angle of the rotating baffle 401 through the control line 9 to close the opening on the left screen door, and the opening on the right screen door remains open. When the train 11 in the right tunnel departs, the pressure in the right tunnel 12 is negative compared to the subway station platform 1, and the train will generate a suction effect. The fluid in the platform will enter the tunnel through the opening on the right perforated screen door 10. At the same time, the air in the subway concourse will replenish the platform, and the air at the subway entrance will enter the concourse and then enter the platform, cooling the subway station without turning on the air conditioner, thus playing a role in saving energy.

[0036] The rotating mechanism 4 includes a fixed column 402 fixedly connected to the tops of the left perforated screen door 2 and the right perforated screen door 10. One end of the fixed column 402 is fixedly connected to a first worm 403. The bottom end of the first worm 403 is meshed with a turbine 404. One end of the first worm 403 is fixedly connected to a main bevel gear 405. One side of the main bevel gear 405 is meshed with a driven bevel gear 406. The middle of the driven bevel gear 406 is fixedly connected to a rotating shaft 407. The top of the rotating shaft 407 is fixedly connected to a small drive motor 408. The bottom end of the rotating shaft 407 is fixedly connected to the rotating baffle 401.

[0037] During specific use, when adjusting the angle of the rotating baffle 401, the rotation of the small driving motor 408 drives the rotation of the rotating shaft 407. Through the rotation of the rotating shaft 407, it is convenient to drive the rotation of the driven bevel gear 406. At the same time, in order to control the angle of the rotating baffle 409, the rotation of the turbine 404 meshes to drive the rotation of the first worm 403. When the first worm 403 rotates, it controls the rotation of the main bevel gear 405 and the speed of the driven bevel gear 406, so as to more conveniently control the opening and closing angle of the rotating baffle 401.

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

[0039] During specific use, when dealing with the pollutants when the subway arrives at the station and when the subway departs during the transitional season, through the cooperation of the set wireless signal receiver 302 and wireless signal transmitter 303, it is convenient to analyze the situation of the left tunnel train 2 and the right tunnel train 11 entering the station inside the left tunnel 7 and the right tunnel 12, and to transmit or receive the signals of entering and leaving the station, so as to facilitate the control and regulation of the pollutants when the subway arrives at the station and when the subway departs during the transitional season. The signal data processing module 304 and the induction control module 305 are used to detect and analyze the particulate matter in the air flow. Then, the automatic control system 3 can control the opening angle of the rotating baffle 4 through the control line 9. The filter net 6 is composed of a PM2.5 prevention and filtering device, which filters the particulate matter in the tunnel and allows the filtered air flow to pass through. At the same time, the induction control module 305 obtains the amount of PM2.5 filtered and discharged, controls the opening and closing of the rotating baffle 401, and at the same time controls and regulates the opening and closing of the rotating baffle 401, so that the air in the subway concourse will supplement the platform, the air at the subway entrance will enter the concourse, and then enter the platform through the concourse, and the subway station can be cooled without turning on the air conditioner, thus playing a role in saving energy.

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