Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, in particular to a safety screen door for rail transportation. Background Art

[0002] With the acceleration of urbanization and the increase in population density, rail transit has become the primary mode of public transportation in many large cities. However, this has also brought with it a significant increase in passenger traffic and increased safety risks, particularly the potential safety hazards of the gap between platforms and trains. The widespread use of safety screen doors for rail transit has not only effectively reduced the incidence of passenger accidents, but also improved train arrival and departure punctuality and operational efficiency, providing a solid guarantee for the safe and efficient operation of urban rail transit.

[0003] Existing rail transit safety screen doors primarily serve as physical barriers, ensuring passengers don't stray onto the tracks while waiting for their train. However, these screen doors offer limited functionality and fail to meet the practical needs of passengers waiting during peak hours. During busy periods, passengers often gather in front of the screen doors on the platform, but it's difficult for them to accurately assess the passenger flow within each car. In this situation, passengers rely solely on their subjective perception of where to stand, without timely information on the train's passenger flow.

[0004] When a train arrives at a station, if a particular car is overcrowded, passengers on the platform often face a problem: they may misjudge their chosen car, preventing them from boarding the train quickly. Passengers rush to switch to a more available car, but time pressure often leads to congestion and even safety hazards. This hasty transfer during peak hours can easily lead to disruptions on the platform and affect overall operational efficiency.

[0005] Therefore, it is necessary to provide a rail transit safety screen door to solve the above technical problems. Utility Model Content

[0006] The purpose of the utility model is to provide a safety screen door for rail transportation to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A safety screen door for rail transit, comprising:

[0009] A fixed door and a movable door, wherein a protective glass is fixedly mounted on the movable door, and mounting brackets are fixedly mounted on both sides of the protective glass above the back of the movable door, a display is fixedly mounted between the two mounting brackets, a horizontal plate is fixedly mounted on the top of the two mounting brackets, a slide is provided at the bottom of the horizontal plate, and an adjusting screw is rotatably mounted inside the slide;

[0010] An adjusting block is sleeved on the outer wall of the adjusting screw rod, and the adjusting block is slidably connected to the slideway. A cleaning plate is fixedly installed on the bottom of the adjusting block, a second brush is fixedly installed on the front of the cleaning plate, and a first brush is fixedly installed on the back of the cleaning plate. A driving mechanism is provided on one side of the horizontal plate.

[0011] Preferably, a support plate is fixedly installed on the back of the movable door below the protective glass, a limiting groove is provided on the top of the support plate, a slider is fixedly installed on the bottom of the cleaning plate, and the slider is slidably connected to the limiting groove.

[0012] Preferably, a plurality of mounting grooves are provided on the sliding contact surface between the adjusting block and the slideway, balls are movably mounted on the mounting grooves, and the balls are in rolling contact with the inner wall of the slideway.

[0013] Preferably, the cleaning plate is located between the display and the movable door, and the position of the first brush corresponds to the display.

[0014] Preferably, the slider is in a T-shaped structure, and the slider is adapted to the limiting groove.

[0015] Preferably, a threaded hole adapted to the adjusting screw is provided on the adjusting block, and the adjusting block is threadedly connected to the adjusting screw through the threaded hole provided thereon.

[0016] Preferably, the first brush and the second brush are both made of microfiber material.

[0017] Preferably, the driving mechanism includes a motor, and the motor is fixedly mounted on one side of the transverse plate, and the driving end of the motor passes through one side of the transverse plate and extends to the interior of the slideway and is fixedly connected to one end of the adjusting screw rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. The utility model uses fixed doors, movable doors, protective glass and displays in conjunction with each other. Before the train arrives at the station, the camera inside the car analyzes the passenger flow in this car in real time and transmits the data to the rail transit control center. The control center then transmits this data to the main controller at the next station to be arrived at. The main controller displays the relevant information in the form of data on the display of each safety shield door, reminding waiting passengers of the passenger flow situation in this car and indicating which cars are relatively empty. In this way, passengers can quickly adjust to the corresponding car before the train arrives at the station, ensuring that they can get on the train smoothly and safely when it arrives, thereby avoiding the chaos and potential safety hazards caused by rushing to change cars due to time constraints. This intelligent solution not only improves the passengers' riding experience, but also effectively reduces congestion and chaos while waiting, thereby improving the operational efficiency and safety of the entire rail transit system.

[0020] 2. This utility model utilizes the mounting bracket, horizontal plate, cleaning plate, motor, adjustment screw, slide, first brush, second brush, and adjustment block to automatically clean the display screen and the inner surface of the protective glass. This ensures excellent clarity when reading information on the display from the outer surface of the protective glass. This automatic cleaning function eliminates the need for manual cleaning of the inner surface of the protective glass and the display, improving safety and overall usability, ensuring passengers always receive clear information during use.

[0021] 3. The utility model uses a supporting plate, a slider and a limiting groove in coordination. During the process of cleaning the display and the protective glass with the cleaning plate, the lateral movement of the cleaning plate drives the slider to slide into contact with the limiting groove on the supporting plate. The supporting plate supports and limits the cleaning plate through the slider, thereby improving the stability of the cleaning plate during daily use. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] See also Figure 1-Figure 5 , an embodiment provided by the utility model:

[0033] A safety screen door for rail transit, comprising:

[0034] A fixed door 1 and a movable door 2, with a protective glass 3 fixedly mounted on the movable door 2, mounting brackets 5 fixedly mounted on both sides of the protective glass 3 above the back of the movable door 2, a display 4 fixedly mounted between the two mounting brackets 5, a horizontal plate 6 fixedly mounted on the top of the two mounting brackets 5, a slide 14 is provided at the bottom of the horizontal plate 6, and an adjusting screw 10 is rotatably mounted inside the slide 14;

[0035] An adjusting block 18 is sleeved on the outer wall of the adjusting screw rod 10, and the adjusting block 18 is slidably connected to the slide 14. A cleaning plate 7 is fixedly installed on the bottom of the adjusting block 18, a second brush 17 is fixedly installed on the front of the cleaning plate 7, and a first brush 16 is fixedly installed on the back of the cleaning plate 7. A driving mechanism is provided on one side of the horizontal plate 6.

[0036] A support plate 8 is fixedly installed on the back of the movable door 2 below the protective glass 3, and a limiting groove 15 is provided on the top of the support plate 8. A slider 11 is fixedly installed on the bottom of the cleaning plate 7, and the slider 11 is slidably connected to the limiting groove 15.

[0037] In one embodiment, the sliding contact surface between the adjustment block 18 and the slideway 14 is provided with a plurality of mounting grooves 13. Ball bearings 12 are movably mounted in these grooves. These balls 12 roll against the inner wall of the slideway 14, effectively reducing friction as the adjustment block 18 moves within the slideway 14, making the adjustment process smoother and more stable. Furthermore, the provision of balls 12 enhances the durability of the entire structure, reduces wear, and ensures stability and reliability over long-term use.

[0038] In one preferred embodiment, the cleaning plate 7 is located between the display 4 and the movable door 2, and the position of the first brush 16 corresponds to the display 4, so that the cleaning plate 7 can effectively clean the display 4 and the inner surface of the protective glass 3 at the same time through the first brush 16 and the second brush 17.

[0039] In one embodiment, the slider 11 is in a T-shaped structure, and the slider 11 is adapted to the limiting groove 15. The T-shaped slider 11 not only provides a stable positioning, but also ensures the smoothness and accuracy of the lateral movement of the cleaning plate 7.

[0040] In one preferred embodiment, a threaded hole adapted to the adjusting screw 10 is provided on the adjusting block 18 , and the adjusting block 18 is threadedly connected to the adjusting screw 10 through the threaded hole provided thereon.

[0041] In one embodiment, both first brush 16 and second brush 17 are made of microfiber, a material with excellent cleaning properties that effectively removes dirt and dust from the display screen 4 and the inner surface of the protective glass 3 without damaging these surfaces. The choice of microfiber ensures an efficient and safe cleaning process, providing passengers with a clear and comfortable visual experience.

[0042] In one of the preferred embodiments, the driving mechanism includes a motor 9, and the motor 9 is fixedly mounted on one side of the transverse plate 6. The driving end of the motor 9 passes through one side of the transverse plate 6 and extends to the interior of the slide 14 and is fixedly connected to one end of the adjusting screw 10.

[0043] The working principle of the present invention is as follows: the electrical components mentioned herein are all electrically connected to a main controller and a power supply. The main controller can be a conventional known device such as a computer that functions as a control device, and the display 4 can realize data transmission with the train's internal camera through wireless communication (such as Wi-Fi and 5G) and Internet of Things technology. The existing disclosed power connection technology is not described in detail herein. The parts not involved in the device are the same as the existing technology or can be implemented using the existing technology. Before the train arrives at the station, the internal camera of each car on the train analyzes the passenger flow in the car and transmits the data in real time to the rail transit control center. The control center transmits this data to the main controller of the next station the train is about to arrive at. The main controller displays this information in the form of data on the display 4 of each movable door 2, reminding waiting passengers to enter the station immediately to check the passenger flow of the train car and reminding passengers which cars have less passenger flow, so that passengers can quickly adjust to the corresponding car before the train arrives. In this way, after the train arrives at the station, passengers can enter the train quickly and safely, avoiding the confusion and potential safety hazards caused by rushing to change cars due to time pressure. This intelligent solution not only improves passengers' riding experience, but also effectively reduces congestion and chaos while waiting for the train, thereby improving the operational efficiency and safety of the entire rail transit system.

[0044] When the display 4 accumulates dust and affects its clarity after prolonged use, the motor 9 is activated. The drive end of the motor 9 rotates the adjustment screw 10. Through the threaded connection between the adjustment screw 10 and the adjustment block 18, and the sliding relationship between the adjustment block 18 and the slideway 14, the adjustment block 18 is caused to move laterally in a stable manner. The movement of the adjustment block 18 drives the cleaning plate 7, which in turn drives the first brush 16 and the second brush 17. The first brush 16 and the second brush 17 automatically clean the screen of the display 4 and the inner surface of the protective glass 3, ensuring that the information on the display 4 remains clear when viewed from the outer surface of the protective glass 3. This automatic cleaning function eliminates the need for manual cleaning of the inner surface of the protective glass 3 and the display 4, improving safety and overall user experience, ensuring that passengers always receive clear information during use.
