Description

Technical Field

[0002] Subway platform doors, also known as screen doors or safety doors, are a system installed at the edge of subway platforms to isolate passengers from the track area, improve safety, save energy and improve the station environment.

[0003] At present, when traditional subway platform doors are in use, when the subway runs to one side of the platform door and stops steadily, the staff will start to open the platform door and the subway car door. After opening, the staff can get on and off the subway. After the people get on and off the subway, the staff will start to close the platform door and the subway car door, and the subway will start to run, so that people can transfer in the subway.

[0004] When the subway stops at one side of the platform door and there is a gap between the two doors after they are opened, people need to step over the gap when passing through, otherwise they may easily step on empty space, causing their legs and feet to be stuck in the gap, thus affecting the normal operation of the subway. Especially when adults and children are taking the subway, children may step on empty space because their steps are smaller. At this time, if the legs and feet are not pulled out of the gap in time, they may be pinched by the closed platform door, affecting the operation of the subway. Utility Model Content

[0036] Embodiment 3

[0037] like Figure 1-Figure 6 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0038] The cleaning assembly 5 includes a cleaning plate 51, which is installed in the cleaning tank 4. A cleaning cotton 52 is fixedly connected to one side of the cleaning plate 51. The upper part of one side of the cleaning plate 51 contacts one side of the infrared sensor 3. The top surface of the cleaning plate 51 is fixedly connected to an extruded damping rod 53, and one end of the extruded damping rod 53 is fixedly connected to an L-shaped plate 54.

[0039] By opening and closing the platform door, one side of the door can be brought into contact with the cleaning cotton 52, so that one side of the door can be cleaned. When replacing it later, first, move the cleaning plate 51 upward so that the cleaning plate 51 squeezes the squeezed damping rod 53, and then make the locking column 55 withdraw from the locking hole 56. After withdrawing, the cleaning plate 51 is tilted and removed from the cleaning tank 4, which is convenient for later cleaning and replacement.

[0040] The working principle and use process of this utility model:

[0041] In use:

[0042] The infrared sensor uses GP2Y0A41SK0F infrared sensor;

[0043] When in use, first, before the subway arrives at the subway station, the infrared sensor 3 is used to check whether there are people stranded at the passage 2. If there are people, the external controller controls the alarm light 10 to prompt the surrounding staff to come and deal with it;

[0044] When the subway arrives at the station, the staff controls the servo motor 69 through the external controller. When the servo motor 69 works, it will drive the bidirectional threaded rod 64 to rotate. When the bidirectional threaded rod 64 rotates, it will drive the left block 65 and the right block 65 to move, thereby driving the left sliding door 67 and the right sliding door 68 to move. When the left sliding door 67 and the right sliding door 68 move, the door can be opened. When the left sliding door 67 and the right sliding door 68 move, the left slider 613 and the right slider 614 will also be driven to move. When the left slider 613 and the right slider 614 move, the U-shaped frame 92 and the moving wheel 95 will be driven to move, thereby moving the moving wheel 95 from one side of the arc-shaped extension plate 94. At this time, the arc-shaped extension plate 94 will be moved out of the storage slot 91 under the action of the reset damping rod 93, and extend to one side of the subway to prevent people from stepping into the air when getting on and off the train.

[0045] As the left sliding door 67 and the right sliding door 68 move, they will contact one side of the cleaning cotton 52, so that one side of the left sliding door 67 and the right sliding door 68 can be cleaned;

[0046] When closing the door, first, the infrared sensor 3 checks whether there is anyone passing through the passage 2. If there is someone passing through, the servo motor 69 is started by the external controller to open the door to avoid the situation of pinching people. At the same time, the alarm light 10 is started to remind the staff to come and check;

[0047] When the cleaning component 5 needs to be replaced later, first put your finger into the disassembly groove 57. At this time, move the cleaning plate 51 upward to squeeze the squeezed damping rod 53. At this time, the locking column 55 will also be disengaged from the locking hole 56. After disengagement, tilt the lower cleaning plate 51. At this time, the cleaning plate 51 can be taken out of the cleaning groove 4, which is convenient for the later replacement of the cleaning plate 51 or the cleaning of the cleaning cotton 52.

[0048] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
