Description

Technical Field

[0001] The invention relates to the field of rail transportation, and in particular to a safe automatic induction door based on rail transportation. Background Art

[0002] In rail transit systems, automatic induction doors are important equipment to ensure passenger safety and efficient train operation. Induction doors are usually installed between platforms and trains to isolate passengers from track areas and prevent passengers from entering dangerous areas. With the rapid development of rail transit and the increasing passenger flow, the frequency and load of induction doors are also increasing. However, during the long-term operation of induction doors, dust, debris and other impurities are easily accumulated in the slide rails. These impurities will affect the normal opening and closing of the induction doors and even cause equipment failure, thus affecting passenger safety and train operation efficiency. Therefore, how to efficiently clean impurities in the slide rails has become a technical problem that needs to be solved in the field of rail transit.

[0003] At present, the cleaning of the slide rails mainly relies on manual operation, that is, the staff regularly use tools to clean the slide rails. However, manual cleaning has the problems of low efficiency and inconvenient operation, especially in the process of frequent opening and closing of the induction door, the cleaning work is difficult to implement. In addition, manual cleaning cannot remove impurities in the slide rails in real time, which easily leads to the accumulation of impurities, thus affecting the normal operation of the induction door. This defect not only increases the equipment maintenance cost, but also may pose a potential threat to passenger safety and train operation efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a safe automatic induction door based on rail transit to solve the problems raised in the above background technology.

Specific implementation manner

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0028] As Figures 1-6 shown, the present invention provides a technical solution:

[0029] A safety automatic induction door based on rail transit includes an embedded base 1. In the middle of the top end of the embedded base 1, a slide rail 2 is provided. The upper end of the slide rail 2 is movably provided with an induction door body 3. A translation mechanism is provided between the slide rail 2 and the induction door body 3. The translation mechanism includes a motor 6. A motor 6 is vertically provided on one side of the middle of the bottom end of the induction door body 3. The output shaft of the motor 6 is fixedly installed with a gear 7. A tooth groove 8 meshing with the gear 7 is provided on the inner wall of the upper end of the slide rail 2. A control box 9 is provided at the top end of the induction door body 3. An installation groove 10 is opened on the inner side of the middle top end of the control box 9. An infrared sensor 11 is detachably provided inside the installation groove 10. A controller 12 is provided in the middle of the inner side of the control box 9 and below the infrared sensor 11. A sound and light alarm 13 is provided at the upper end of the middle of the front of the induction door body 3. The sound and light alarm 13 is electrically connected to the infrared sensor 11 through the controller 12;

[0030] In this embodiment, an infrared sensor 11 and a sound and light alarm 13 are provided at the top end of the induction door body 3, which can detect in real time whether there is a passenger trying to climb over the induction door. When an abnormal situation is detected, the controller 12 will immediately activate the sound and light alarm 13 to send an alarm signal to remind the staff or passengers to pay attention to safety. This intelligent safety protection mechanism not only reduces the risk of passengers climbing over the induction door, but also improves the overall safety in the rail transit environment. In addition, during the cleaning process, impurities are effectively collected in the collection box 26 of the side box 25, avoiding the potential harm of impurity scattering to passengers and equipment, and further ensuring the safety of passengers and equipment.

[0031] As shown in Figure 2 , Figure 3 , Figure 4 and Figure 5 the figure, rotating tubes 4 are movably arranged on both sides of the bottom end of the induction door body 3. Guide mechanisms are arranged at the upper and lower ends of the rotating tubes 4. The guide mechanisms include guide disks 14. Guide disks 14 are respectively arranged at the upper and lower ends outside the rotating tubes 4. The guide disks 14 are movably connected to the rotating tubes 4 through bearings. Guide grooves 15 are symmetrically arranged on both sides of the inner wall below the slide rail 2. The bottom guide disks 14 are slidably connected to the guide grooves 15. A plurality of horn-shaped nozzles 27 are arranged at equal arcs on the outer wall of the guide disks 14. A plurality of air holes 16 communicating with the horn-shaped nozzles 27 are arranged at equal arcs on the outer walls of the upper and lower ends of the rotating tubes 4. The bottoms of the two guide mechanisms are communicated with a tee pipe 5. A blowing mechanism is arranged in the middle of the bottom end of the tee pipe 5. The blowing mechanism includes a rotary joint II 17. The rotary joint II 17 is arranged in the middle of the bottom end of the tee pipe 5. The bottom end of the rotary joint II 17 is communicated with a fixed pipe 18 through an elbow. The other end of the fixed pipe 18 is movably sleeved with a sleeve 19. One end of the sleeve 19 away from the fixed pipe 18 is communicated with an air inlet 20. Rotating shafts 21 are arranged at the upper and lower ends of the air inlet 20. A retaining net II 22 is arranged on the front surface of the air inlet 20. A retaining ring 23 is arranged outside the fixed pipe 18 near the elbow. A spring 24 is arranged between the retaining ring 23 and the sleeve 19 and outside the fixed pipe 18. Both sides of the top end of the tee pipe 5 are communicated with the rotating tube 4 through rotary joints I 31. Side boxes 25 are communicated on both sides of the slide rail 2. A collection box 26 is movably arranged inside the side boxes 25. An exhaust port 28 is arranged in the middle of the top end of the collection box 26. A retaining net I 29 is arranged at the upper end inside the exhaust port 28. A handle 30 is arranged outside the upper end of the collection box 26;

[0032] In this embodiment, by utilizing the airflow generated during the train operation and combining the designs of the blowing mechanism and the guide mechanism, automatic cleaning of the guide grooves 15 and the tooth grooves 8 in the slide rail 2 is achieved. The airflow is ejected through the horn-shaped nozzles 27, efficiently removing impurities and avoiding the problems of low efficiency and inconvenient operation of manual cleaning. At the same time, the arrangements of the fixed pipe 18, the sleeve 19, the spring 24 and the rotary joint II 17 ensure the stable connection of the pipeline when the induction door moves, further improving the continuity and reliability of cleaning. This design effectively prevents the influence of impurity accumulation on the normal opening and closing of the induction door, significantly improving the operation stability and service life of the induction door.

[0033] Working principle: When the train arrives at or departs from the station, the airflow generated during the train operation enters the blowing mechanism through the air inlet 20. The airflow passes through the sleeve 19, the fixed pipe 18, and the tee pipe 5 in sequence, and finally enters the rotating pipe 4 through the rotary joint 31. The guide disks 14 at the upper and lower ends of the rotating pipe 4 are slidably connected to the guide grooves 15 below the slide rail 2. At the same time, the horn-shaped nozzles 27 on the outer wall of the guide disk 14 are communicated with the air holes 16 on the rotating pipe 4. When the induction door body 3 moves, the motor 6 drives the gear 7 to rotate, and the gear 7 meshes with the tooth grooves 8 on the slide rail 2, so that the induction door body 3 moves smoothly along the slide rail 2. At this time, the guide disk 14 rotates in the guide groove 15, driving the horn-shaped nozzle 27 to rotate synchronously, and the airflow is ejected through the horn-shaped nozzle 27 to efficiently clean the guide groove 15 and the tooth grooves 8. In the blowing mechanism, the fixed pipe 18 and the sleeve 19 are telescopically connected through the spring 24 and the retaining ring 23, ensuring that when the tee pipe 5 moves horizontally, the fixed pipe 18 and the sleeve 19 can flexibly expand and contract to maintain the connectivity of the pipeline. The setting of the rotary joint 17 further enhances the flexibility of the pipeline, so that the tee pipe 5 will not affect the stable transportation of the airflow during the movement, ensuring that the blowing mechanism can work continuously and efficiently when the induction door moves, and at the same time avoiding the problems of disconnection or leakage of the pipeline due to movement. During the cleaning process, some impurities are ejected from the upper end of the slide rail 2 by the airflow, and the other part of the impurities are carried by the airflow into the side boxes 25 on both sides of the slide rail 2. A collection box 26 is movably arranged inside the side box 25. The impurities enter the collection box 26, and the air is discharged through the exhaust port 28. The first retaining net 29 prevents the impurities from escaping. The handle 30 at the upper end of the collection box 26 is convenient for regularly cleaning the impurities to ensure the long-term stable operation of the induction door. In addition, the infrared sensor 11 is installed in the control box 9 at the top of the induction door body 3 to detect whether there is a passenger trying to climb over the induction door. When an abnormality is detected, the controller 12 will activate the sound and light alarm 13 to send an alarm signal to remind the staff or passengers to pay attention to safety.

[0034] It should be noted that a rubber corrugated pipe is provided outside the sleeve 19 and the retaining ring 23 of the device, and an opening is provided between the side box 25 and the embedded seat 1 for impurities to enter the collection box 26.
