Abstract
Description
Technical Field
[0001] This utility model relates to the field of subway platform screen doors, specifically to a self-cleaning device for subway platform screen doors. Background Technology
[0002] Platform screen doors (PSM) are glass curtain walls that enclose the railway platform and train boarding / alighting area on a subway platform. These doors are installed along the track side of the subway platform to separate the platform area from the track area. When a train arrives, the sliding doors in the glass curtain wall open to allow passengers to board and alight. Because dust raised by the trains accumulates on the inner surfaces of the PSM doors, and these surfaces cannot be cleaned during normal subway operation, a significant amount of dust on the sliding doors can cause excessive dust to be stirred up at the train entrances and exits when the doors are opened, negatively impacting the passenger experience. Utility Model Content
[0003] The purpose of this invention is to provide a self-cleaning device for subway platform screen doors. This device uses a rotating rod to enable the cleaning section and the liquid absorption section to clean and dry the inside of the moving door in sequence, thereby reducing the amount of dust generated when the moving door is opened and improving the passenger's riding experience.

[0018] The components include a rotating rod 1, a cavity 11, a liquid outlet 12, a first roller 13, a second roller 14, an insertion rod 15, a limiting rod 16, a liquid inlet 17, a sealing cover 18, an anti-slip sleeve 19, a liquid outlet 2, a liquid suction part 3, a movable door 4, a support base 41, a slot 42, an arc groove 43, and an anti-slip pad 5. Detailed Implementation
[0019] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.
[0020] See Figures 1-5 This embodiment discloses a self-cleaning device for subway platform screen doors, comprising a rotating rod 1, a liquid outlet 2, and a liquid suction part 3. The upper and lower ends of the rotating rod 1 are respectively rotatably mounted in the upper and lower support seats 41 of the movable door 4. The liquid outlet 2 is located on one side of the rotating rod 1 and is used to output cleaning liquid. The liquid suction part 3 is located on the other side of the rotating rod 1 and is used to absorb the liquid. When the rotating rod 1 rotates, the liquid outlet 2 and the liquid suction part 3 respectively come into contact with the inner side of the movable door 4.
[0021] This invention is installed on both sides of the entrance and exit of a subway platform screen door, with the liquid outlet 2 fitting against the inner surface of the movable door 4. When the movable door 4 moves to open, the liquid outlet 2 on the rotating rod 1 fits against the inner surface of the movable door 4, keeping the liquid outlet 2 stationary while the inner surface of the movable door 4 moves, thus applying cleaning fluid to the inner surface of the movable door 4 for cleaning. When the movable door 4 moves to close, the rotating rod 1 rotates, causing the liquid suction 3 to fit against the inner surface of the movable door 4, keeping the liquid suction 3 stationary while the inner surface of the movable door 4 moves, thus absorbing the cleaning fluid adhering to the inner surface of the movable door 4 and keeping the movable door 4 dry. Therefore, this invention achieves cleaning of the movable door 4 by sequentially cleaning and drying the inner surface of the movable door 4 through the cleaning part and the liquid suction part 3, thereby reducing the amount of dust generated when the movable door 4 is opened and improving the passenger's riding experience.
[0022] See Figures 2-4 The rotating rod 1 is provided with a plurality of first rollers 13 and a plurality of second rollers 14. The plurality of first rollers 13 are arranged coaxially on the side where the liquid outlet 2 is located, and the plurality of second rollers 14 are arranged coaxially on the side where the liquid suction 3 is located. The first rollers 13 and the second rollers 14 are rotatably mounted on the rotating rod 1 through one-way bearings with opposite rotation directions.
[0023] In this embodiment, under the action of the one-way bearing, the first roller 13 can only rotate counterclockwise, and the second roller 14 can only rotate clockwise.
[0024] When the liquid outlet 2 is attached to the inner side of the movable door 4, the first roller 13 can only rotate counterclockwise. At this time, the movable door 4 moves to the left relative to the rotating rod 1 to open, and the first roller 13 rotates normally. The liquid outlet 2 cleans the movable door 4. Then, when the movable door 4 moves to the right to close, since the first roller 13 cannot rotate clockwise, the friction between the first roller 13 and the movable door 4 drives the rotating rod 1 to rotate clockwise, so that the liquid suction part 3 is attached to the movable door 4. The second roller 14 can only rotate clockwise. When the movable door 4 moves to the right to close, the second roller 14 rotates normally, and the liquid suction part 3 absorbs the cleaning liquid. When the movable door 4 opens again, it moves to the left. Since the second roller 14 cannot rotate counterclockwise, the friction between the second roller 14 and the movable door 4 drives the rotating rod 1 to rotate counterclockwise, so that the liquid outlet 2 is attached to the movable door 4. By repeating the above steps, the cleaning operation of the movable door 4 can be achieved.
[0025] In this invention, the rotation of the rotating rod 1 is achieved by the action of the first roller 13 and the second roller 14, eliminating the need for an additional drive device to drive the rotating rod 1 to rotate. This reduces the production and use costs of this invention and also reduces the complexity of its structure, thereby lowering the failure rate of this invention.
[0026] See Figure 2 , Figure 5 The upper and lower ends of the rotating rod 1 are provided with insertion rods 15 and limiting rods 16. The upper and lower support seats 41 of the movable door 4 are provided with slots 42 and arc grooves 43. The insertion rods 15 are adapted to be rotatably inserted into the slots 42. The limiting rods 16 are adapted to be slidably disposed in the arc grooves 43. When the liquid outlet 2 and the liquid suction 3 are respectively in contact with the movable door, the limiting rods 16 abut against the horizontal ends of the arc grooves 43.
[0027] The rotating rod 1 is rotatably installed in the support seats 41 on the upper and lower sides of the movable door 4 by the cooperation of the insertion rod 15 and the slot 42. The rotation angle of the rotating rod 1 is limited by the limiting rod 16 and the arc groove 43, so that the liquid outlet 2 and the liquid suction 3 can remain parallel and close to the movable door 4, which can increase the contact area between the liquid outlet 2 and the liquid suction 3 and the movable door 4, thereby improving the cleaning and drying effect of the liquid outlet 2 and the liquid suction 3.
[0028] See Figure 4 The rotating rod 1 is provided with a cavity 11 for storing cleaning fluid, and a plurality of outlet holes 12 for connecting the cavity 11 and the outlet part 2 are provided on the side of the rotating rod 1.
[0029] In this invention, the liquid outlet 2 is made of a material that can absorb water and moisten. The cleaning liquid in the cavity 11 comes into contact with the liquid absorption part 3 through the liquid outlet 12 and wets the liquid absorption part 3. Thus, when the liquid absorption part 3 is attached to the inner side of the movable door 4 and moves, the cleaning liquid can be evenly applied to the movable door 4 to clean the movable door 4. At the same time, the liquid outlet 2 can realize the slow and continuous output of cleaning liquid, reducing the risk of excessive disinfectant adhering to the movable door 4 and causing disinfectant dripping, which affects the normal operation of the movable door 4, and ensuring the normal operation of the subway train.
[0030] See Figure 4 The rotating rod 1 is provided with a liquid inlet hole 17 that communicates with the cavity 11, and the outer end of the liquid inlet hole 17 is connected to a sealing cap 18 by a threaded seal.
[0031] By unscrewing the sealing cap 18, it is easy to inject cleaning fluid into the cavity 11, which improves the convenience of using this utility model; by screwing on the sealing cap 18, the risk of disinfectant leakage from the cavity 11 is reduced, which improves the stability of using this utility model.
[0032] See Figure 4 The outer surfaces of the first roller 13 and the second roller 14 are both covered with anti-slip sleeves 19.
[0033] The anti-slip sleeve 19 reduces the probability of slippage when the first roller 13 and the second roller 14 interact with the movable door 4, ensuring that the movable door 4 can be driven to rotate clockwise by the first roller 13 when it moves to the right, and can be driven to rotate counterclockwise by the second roller 14 when it moves to the left, thus improving the stability of the operation of this utility model.
[0034] In this invention, the anti-slip sleeve 19 is made of elastic material. When the rotating rod 1 rotates, the anti-slip sleeve 19 is compressed and undergoes elastic deformation, which prevents the first roller 13 and the second roller 14 from hindering the rotation of the rotating rod 1 and ensures that the rotating rod 1 can rotate smoothly.
[0035] In addition, an anti-slip pad 5 is provided on the rotating rod 1 located between the first roller 13 and the second roller 14. When the first roller 13 is separated from the movable door 4, the rotating part 1 can still rotate clockwise until the second roller 14 contacts the movable door 4 through the friction between the anti-slip pad 5 and the movable door 4. And when the second roller 14 is separated from the movable door 4, the rotating part 1 can still rotate counterclockwise until the first roller 13 contacts the movable door 4 through the friction between the anti-slip pad 5 and the movable door 4, thus ensuring the normal operation of this utility model.
[0036] The above description in this specification is merely illustrative of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
