[0022] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods:

[0023] like Figure 1-5 As shown, the utility model provides a retractable anti-stepping device for a subway platform, comprising a mounting plate 4, one end of which is fixedly connected to a platform body 1, and a protection component 2 is arranged on the top of the platform body 1, the protection component 2 is arranged on the top of the platform body 1, the protection component 2 comprises a protection door 201, a transmission mechanism 3 is arranged on one end of the mounting plate 4, the transmission mechanism 3 comprises a driving component 30 and a driving component 31, a warning component 5 and a cleaning component 6 are arranged on one side of the mounting plate 4, the warning component 5 comprises a rotating shaft 501, a cylinder 502 and a warning plate 503, a fluorescent plate is installed on the top of the warning plate 503, the driving component 30 drives the warning plate 503 to rotate through the protection door 201 and the rotating shaft 501, the cylinder 502 can drive the warning plate 503 to reciprocate, the cleaning component 6 comprises a nozzle 601, the transmission component 31 drives the nozzle 601 to rotate through the rotating shaft 501, when the warning plate 503 rotates, the nozzle 601 also rotates accordingly, and the two rotate in opposite directions.

[0024] Before the train arrives at the station, the two protective doors 201 are attached and in working state, and can achieve the protective effect, reducing the probability of passengers falling into the track. After the train arrives at the station, the control terminal in the station can control the two protective doors 201 to move back and forth, and slide in their respective mounting frames 202. When one of the protective doors 201 moves, the driving component 30 drives the rotating shaft 501 to rotate. After the rotating shaft 501 rotates, it drives the cylinder 502 and the warning plate 503 to rotate. Since a fluorescent plate is installed on the top of the warning plate 503, when the two protective doors 201 are retracted, the warning component 5 can work. By setting the fluorescent plate, passengers can pay attention to the distance between the platform body 1 and the train when stepping on the train. At the same time, the linkage method is adopted. After the two protective doors 201 are retracted, the warning component 5 can directly remind passengers, reduce the probability of passengers stepping into the air, and improve the safety protection function. When the distance of the fluorescent plate is too low, the cylinder 502 is started, and the output end of the cylinder 502 extends to push the fluorescent plate to move vertically upward, so as to be applicable to scenes of different heights, further improving the applicability;

[0025] When the driving component 30 is in operation, it cooperates with the transmission component 31, so that the transmission component 31 drives the nozzle 601 to rotate, and the nozzle 601 sprays clean water. At this time, the fluorescent plate and the nozzle 601 can both rotate, so that the clean water sprayed by the nozzle 601 can clean the dust on the surface of the fluorescent plate, improve the cleanliness of the fluorescent plate, and then improve the warning effect and safety. When the train arrives at the station, the fluorescent plate can be automatically cleaned without manual operation, which further improves the applicability;

[0026] When the protection door 201 is closed again, the nozzle 601 and the fluorescent plate are reversed to the initial position through the transmission mechanism 3, so as to achieve the effect of repeated use and further improve the applicability.

[0027] In one embodiment, the warning component 5 also includes a support member 504, the rotating shaft 501 is rotatably connected to the mounting plate 4, the support member 504 is fixedly sleeved on the rotating shaft 501, and is fixedly connected to the cylinder 502, the warning plate 503 is fixedly connected to the output end of the cylinder 502, the rotating shaft 501 drives the cylinder 502 to rotate through the rotating shaft 501, and the support member 504 drives the warning plate 503 to move linearly.

[0028] When the rotating shaft 501 rotates, it first drives the supporting member 504 to rotate. When the supporting member 504 rotates, it drives the cylinder 502 and the fluorescent plate to rotate. When the fluorescent plate is too low, the cylinder 502 is started, and the output end of the cylinder 502 extends to push the fluorescent plate to move vertically upward, so that it is suitable for scenes at different heights, further improving applicability.

[0029] In one embodiment, the driving assembly 30 includes a connecting rod 301, a rack 302, a driving gear 303 and a push rod 304. One end of the connecting rod 301 is fixedly connected to the rack 302, and the other end is slidably matched with the mounting plate 4. The push rod 304 is fixedly installed at one end of one of the protective doors 201. The driving gear 303 is fixedly sleeved on the rotating shaft 501 and meshes with the rack 302.

[0030] When one of the protective doors 201 moves, it drives the push rod 304 to move. After the push rod 304 moves a certain distance, the push rod 304 presses against the connecting rod 301 and moves horizontally. When the connecting rod 301 moves, it drives the rack 302 to move horizontally. When the rack 302 moves, it engages with the driving gear 303 to drive the driving gear 303 to rotate. When the driving gear 303 rotates, it drives the rotating shaft 501 to rotate. After the rotating shaft 501 rotates, it drives the cylinder 502 and the warning plate 503 to rotate through the support 504, so that the fluorescent plate can be unfolded when the protective door 201 is closed, thereby improving applicability.

[0031] In one embodiment, the cleaning assembly 6 also includes a driven shaft 602 and a water tank 603. The driven shaft 602 is rotatably connected to one end of the mounting plate 4. The water tank 603 is fixedly installed on the driven shaft 602. The water tank 603 has a built-in water pump. The nozzle 601 is fixedly installed on the water outlet end of the water tank 603.

[0032] When the rotating shaft 501 rotates, the rotating shaft 501 drives the driven shaft 602 and the water tank 603 to rotate through the transmission assembly 31. When the water tank 603 rotates, it drives the rear nozzle 601 to rotate, so that the dust on the fluorescent plate can be cleaned when the fluorescent plate rises, thereby improving the fluorescent effect.

[0033] In one embodiment, the transmission assembly 31 includes a transmission shaft 311, a transmission gear 312, a pulley 313 and a belt 314.

The two pulleys 313 are respectively fixedly sleeved on the transmission shaft 311 and the driven shaft 602, and the belt 314 is sleeved on the two pulleys 313.

[0034] When the driving gear 303 rotates, it drives the transmission gear 312 to rotate by meshing with the transmission gear 312. After the transmission gear 312 rotates, it drives the transmission shaft 311 to rotate. After the transmission shaft 311 rotates, it drives the driven shaft 602 to rotate through the pulley 313 and the belt 314. When the driven shaft 602 rotates, it drives the water tank 603 and the nozzle 601 to rotate. At this time, the nozzle 601 is started, and the built-in water pump of the water tank 603 sprays clean water from the nozzle 601, so that the fluorescent plate and the nozzle 601 can both rotate. At this time, the clean water sprayed by the nozzle 601 can clean the dust on the surface of the fluorescent plate, thereby improving the fluorescent effect and warning effect.

[0035] In one embodiment, the protection component 2 further includes a mounting frame 202 , which is fixedly connected to the top of the platform body 1 , and the protection door 201 is disposed in the mounting frame 202 and slidably cooperates with the mounting frame 202 .

[0036] The mounting frame 202 is used to hide the protective door 201 .

[0037] In one embodiment, a plurality of mounting holes are formed on the top of the warning plate 503 .

[0038] The mounting holes are used to install the fluorescent panel to improve applicability.

[0039] The following is a detailed description of the working principle of the retractable anti-stepping device in the subway platform gap.

[0040] Before the train arrives at the station, the two protective doors 201 are fitted and in working condition, and can achieve the protective effect, reducing the probability of passengers falling into the track. After the train arrives at the station, the control terminal in the station can control the two protective doors 201 to move back and forth, and slide in their respective mounting frames 202. When one of the protective doors 201 moves, it drives the push rod 304 to move. After the push rod 304 moves a certain distance, the push rod 304 moves horizontally against the connecting rod 301. When the connecting rod 301 moves, it drives the rack 302 to move horizontally. When the rack 302 moves, it can drive the driving gear 303 by meshing with the driving gear 303. The wheel 303 rotates, and the driving gear 303 rotates, driving the rotating shaft 501 to rotate. After the rotating shaft 501 rotates, the cylinder 502 and the warning plate 503 are driven to rotate through the support 504. Since a fluorescent plate is installed on the top of the warning plate 503, when the two protective doors 201 are retracted, the warning component 5 can work. By setting the fluorescent plate, passengers can pay attention to the distance between the platform body 1 and the train when stepping on the train. At the same time, the warning component 5 adopts a linkage method. After the two protective doors 201 are retracted, the warning component 5 can directly remind the passengers, reduce the probability of passengers stepping on empty space, and improve the safety protection function;

[0041] When the driving gear 303 rotates, it meshes with the transmission gear 312 to drive the transmission gear 312 to rotate. After the transmission gear 312 rotates, it drives the transmission shaft 311 to rotate. After the transmission shaft 311 rotates, it drives the driven shaft 602 to rotate through the pulley 313 and the belt 314. When the driven shaft 602 rotates, it drives the water tank 603 and the nozzle 601 to rotate. At this time, the nozzle 601 is started, and the built-in water pump of the water tank 603 sprays clean water from the nozzle 601, so that the fluorescent plate and the nozzle 601 can both rotate. At this time, the clean water sprayed by the nozzle 601 can clean the dust on the surface of the fluorescent plate, improve the cleanliness of the fluorescent plate, and then improve the warning effect and safety. When the train arrives at the station, the fluorescent plate can be automatically cleaned without manual operation, which further improves the applicability;

[0042] When the protective door 201 is closed again, the push rod 304 no longer applies force to the connecting rod 301. At this time, the support member 504 drives the rotating shaft 501 to rotate under the action of its own gravity. After the rotating shaft 501 reverses, the transmission mechanism 3 drives the nozzle 601 to reverse to the initial position, thereby achieving the effect of reuse and further improving applicability.

[0043] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
