[0027] Working principle: When a subway platform gap protection device is used, in the initial state, the subway lane 101 is first set on one side of the subway platform body 1. The track 102 is fixed on the subway lane 101 using the fixing block 103. At the same time, the protective door 2 is fixed on the upper surface of the subway platform body 1, and the opening and closing of the two movable doors 202 in a single set is controlled by the slide rail 201 to block passengers and prevent passengers from accidentally falling into the subway lane 101. The movable groove 301 and inner groove 306 opened on one side of the subway platform body 1 are respectively equipped with a protective plate 303 and a telescopic cylinder 308. The hinge joint 309 at the top of the telescopic cylinder 308 is connected to the connecting rod 305 on the inner side of the protective plate 303 through the push arm 310, so as to control the protective plate 303 to rotate up and down to expand or retract to fill the gap between the subway platform body 1 and the subway vehicle.
[0028] When it is necessary to prevent passengers' feet or items from falling through the gap between the subway platform body 1 and the subway car, firstly, after the subway car stops and the car door is aligned with the movable door 202, the telescopic cylinder 308 extends and pushes the push arm 310 upward using the hinge joint 309. The upward-moving push arm 310 pushes the protective plate 303 upward under the limit of the rotating rod 302 through the connecting rod 305, so that the outer wall of the protective plate 303 contacts the outer wall of the subway car, blocking the gap between the subway platform body 1 and the car. Then, the movable door 202 is opened to allow passengers to get on and off the car. After getting on and off the car and the movable door 202 is closed, the telescopic cylinder 308 retracts and uses the hinge joint 309 to pull the push arm 310 downward and drive the protective plate 303 to rotate downward and retract into the movable slot 301. This device is convenient for preventing passengers' feet or items from falling through the gap between the subway platform body 1 and the subway car.
