Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0021] Embodiment one: please refer to the drawings Figure 1 -Appendix Figure 4 A subway platform shielding door prevents sundry baffle, including platform surface 2, one side of platform surface 2 is equipped with train body 1, the two ends of the side of platform surface 2 close to train body 1 are fixedly installed with protective panel 3, two groups of protective doors 4 are equipped between two groups of protective panel 3, the inside of train body 1 is equipped with two groups of shielding doors 6, locking device 5 is equipped between two groups of protective doors 4 and two groups of protective panel 3, and protective device 7 is equipped between the bottom of two groups of protective panel 3, locking device 5 includes servo motor 501 fixedly installed in the inside of left protective panel 3, two groups of stable sliding blocks 504 are connected with servo motor 501 through bidirectional screw rod 502, guide groove 503 is fixedly installed between the upper end of two groups of protective panel 3, two groups of limit sliding blocks 505 are fixedly installed on the inner side upper end of two groups of protective doors 4, protective baffle 508 is fixedly installed on the inner wall of the opposite side of two groups of protective doors 4, the end of bidirectional screw rod 502 away from servo motor 501 is rotationally connected to the inside of right protective panel 3, two groups of stable sliding blocks 504 are respectively screw-connected on the circumferential surface of the two ends of bidirectional screw rod 502, and the other end of two groups of stable sliding blocks 504 is respectively fixedly connected with the inner wall of two groups of protective doors 4, limit sliding block 505 is slidingly connected in the inside of guide groove 503, the upper and lower two ends of left protective door 4 close to the side of right protective door 4 are provided with insertion hole 506, and the surface of the upper and lower two ends of right protective door 4 is fixedly installed with insertion column 507 matched with insertion hole 506, the inner wall of insertion hole 506 and the top of insertion column 507 are fixedly installed with sensing probe, the side of protective baffle 508 away from protective door 4 is close to the outside of shielding door 6, and protective baffle 508 does not contact with shielding door 6.

[0022] Insertion column 507 is inserted in insertion hole 506, whether protective door 4 is tightly closed is detected through sensing probe, if not, two groups of protective baffles 508 are not completely attached, indicating that sundry or passenger clothes and other articles are clamped, at this time, staff can be informed in the first time, when shielding door 6 and protective door 4 are closed, protective baffle 508 moves synchronously with protective door 4, and always keeps the same position with shielding door 6, so that the gap between protective door 4 and shielding door 6 is always blocked.

[0023] Specifically, the servo motor 501 drives the bidirectional screw 502 to rotate, and the two sets of stabilizing sliders 504 move towards or away from each other on the bidirectional screw 502, thereby controlling the two sets of protective doors 4 to move simultaneously, thus opening and closing the protective doors 4. When the protective door 4 is closed, the insert 507 is inserted into the insertion hole 506. At this time, the two sets of protective baffles 508 approach each other and fit together. The protective baffles 508 block the gap between the protective door 4 and the shielding door 6, preventing passengers from crowding when the doors are closed, which could cause clothing or personal belongings to be caught between the shielding door 6 and the protective door 4.

[0024] Example 2: Please refer to the appendix. Figure 1 - Appendix Figure 2 and appendix Figure 5 Furthermore, based on Embodiment 1, the protective device 7 includes a stable base plate 701 fixedly installed at the bottom of the two sets of protective panels 3. The surface of the stable base plate 701 is provided with a directional slide rail 702 adapted to the protective door 4. The bottom of the stable base plate 701 is provided with an installation groove 703 on the side near the shielding door 6. An electric telescopic baffle 704 is slidably connected inside the installation groove 703, and the electric telescopic baffle 704 does not contact the train body 1.

[0025] The electric telescopic barrier 704 can automatically extend and retract. When the platform screen door 6 and the protective door 4 are opened, the electric telescopic barrier 704 extends automatically. When closed, the electric telescopic barrier 704 retracts automatically into the stable base plate 701. The extension and retraction of the electric telescopic barrier 704 can be controlled by the hydraulic rod. The electric telescopic barrier 704 is installed under the platform surface 2, so it is not easy for passengers to step on the electric telescopic barrier 704.

[0026] Specifically, when the platform screen door 6 and the protective door 4 are in the open state, passengers enter the train body 1. The electric telescopic baffle 704 at the bottom extends from the mounting groove 703 of the stable base plate 701 and gets very close to the train body 1. The electric telescopic baffle 704 blocks the bottom gap between the train body 1 and the platform surface 2, preventing debris from falling from the gap to the bottom of the train body 1 and causing damage to the track equipment.

[0027] Working principle of this utility model: This utility model is a debris-proof baffle for subway platform screen doors. First, the servo motor 501 drives the bidirectional screw 502 to rotate, and the two sets of stabilizing sliders 504 move towards or away from each other on the bidirectional screw 502, thereby controlling the simultaneous movement of the two sets of protective doors 4, which play the role of opening and closing the protective doors 4. When the protective doors 4 are closed, the insert 507 is inserted into the insert hole 506. The sensor probe detects whether the protective doors 4 are completely closed. After closing, the two sets of protective baffles 508 approach each other and stick together. The protective baffles 508 block the gap between the protective doors 4 and the screen door 6. After the screen door 6 and the protective doors 4 are opened, the electric telescopic baffle 704 at the bottom extends out from the mounting groove 703 of the stabilizing base plate 701 and approaches the train body 1. The electric telescopic baffle 704 blocks the bottom gap between the train body 1 and the platform surface 2. At this point, the entire process is completed.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
