Description

Technical Field

[0001] This utility model relates to the field of sound and light alarm technology, and in particular to a safety early warning device for trains entering and leaving railway stations. Background Technology

[0002] With the continuous upgrading of the railway transportation system, the safety management standards for train platforms are becoming increasingly stringent. Although existing platforms are equipped with basic protective facilities, there are still shortcomings in terms of dynamic risk early warning. To strengthen safety control in platform areas, modern railway systems generally adopt intelligent early warning technology, deploying audible and visual alarm devices at key locations on the platform to build a dynamic perception and real-time warning system for train arrivals. When a train approaches the platform, the system relies on track sensors and intelligent recognition modules to accurately capture the train's position information, immediately triggering the audible and visual alarms to issue clear voice prompts and flashing warning signals, effectively guiding platform personnel to avoid dangerous areas.

[0003] As per existing technology, patent CN220338052U discloses an audible and visual alarm, comprising a main body, a monitoring frame disposed on the lower rear side of the main body, an upper mounting slot provided on the monitoring frame, a mounting plate disposed on the lower inner side of the main body, the mounting plate being inserted into the inner side of the mounting slot, a monitoring sensor disposed inside the monitoring frame, one end of the monitoring sensor being located inside a monitoring through hole; the length of the monitoring frame is the same as the length of the main body, and the monitoring through hole penetrates the monitoring frame, with both ends of the monitoring through hole connected to a detection tube; a fixing plate disposed on the rear side of the main body, with screw holes provided at each of the four corners of the fixing plate; the monitoring frame is designed so that, in use, the monitoring frame is installed on one side of the lower end of the main body by the engagement of the mounting plate and the mounting slot, and the monitoring frame can be easily and quickly removed as needed to disassemble and replace the monitoring sensor inside.

[0004] Although the audible and visual alarm in the aforementioned patent allows for convenient and quick removal and replacement of the internal monitoring sensors, it still has certain drawbacks:

[0005] Existing audible and visual alarms have significant deficiencies in vibration resistance. Low-frequency vibrations of 5-50Hz generated when trains enter or leave the station, transient impact loads caused by track settlement, and resonance effects accumulated during long-term service can all lead to equipment failure. Specifically, this manifests as decreased reliability of internal components, such as buzzer solder joints detaching due to vibration fatigue and poor contact in LED bead pins; fatigue fracture of structural components, typically cracks or even breakage at the mounting lugs of the outer casing; and vibration also accelerates the wear of sealing rings, leading to a decrease in the equipment's waterproof rating and severely affecting the stability of the platform safety warning function. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a safety early warning device for trains entering and leaving railway stations. The specific technical solution is as follows:

[0007] A railway station train entry and exit safety early warning device includes an alarm body. An upper connecting plate is fixedly connected to the upper end of the back of the alarm body. A fixing plate is provided on the back of the alarm body. An inverted U-shaped groove is opened on the fixing plate. A lower connecting plate is slidably connected to the lower end of the fixing plate. Dampers are installed at both ends of the top of the lower connecting plate. The upper end of the damper is installed with the upper connecting plate. A buffer elastic element is sleeved on the outside of the damper. The upper end of the buffer elastic element is fixedly connected to the upper end of the damper. The lower end of the buffer elastic element is fixedly connected to the lower connecting plate.

[0008] In some embodiments, both ends of the upper connecting plate are provided with upper connecting grooves, and an upper connecting block is slidably connected inside the upper connecting groove. The upper connecting block is fixedly connected to the damper. An upper horizontal slot is provided in the middle of the upper connecting plate, and an upper horizontal insert rod is slidably connected inside the upper horizontal slot. The upper horizontal insert rod matches the upper connecting block. Both sides of the upper end of the fixed plate are provided with end connecting grooves that match the upper horizontal insert rod. Buffer pads are fixedly connected to the inner walls of the upper connecting groove and the end connecting groove.

[0009] In some embodiments, a baffle is fixedly connected to one end of the upper horizontal insert rod, a gripping plate is fixedly connected to the side of the baffle away from the fixed plate, a slot is opened at the end of the upper horizontal insert rod away from the baffle, a stop block is slidably connected inside the slot, and elastic blocks are fixedly connected to both sides of the bottom of the stop block, the elastic blocks matching the upper horizontal insert rod.

[0010] In some embodiments, both ends of the lower connecting plate are provided with lower connecting grooves, and a lower connecting block is slidably connected inside the lower connecting groove. The lower connecting block is fixedly connected to the bottom of the damper. The upper end of the lower connecting plate is provided with a lower horizontal slot. A lower horizontal insert rod that matches the lower connecting block is slidably connected inside the lower horizontal slot. One end of the lower horizontal insert rod is fixedly connected to an end plate, and a gripping groove is provided on the side of the end plate away from the lower horizontal insert rod.

[0011] In some embodiments, both ends of the bottom of the lower connecting plate are slidably connected to a sliding plate, and the bottom of the fixing plate is provided with a groove that matches the sliding plate.

[0012] In some embodiments, a magnetic block is provided at the top end of the skateboard away from the lower connecting plate, and the magnetic block is fixedly connected to the skateboard.

[0013] In some embodiments, the end of the slide is trapezoidal, and a pusher block is fixed to the bottom of the slide.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] Firstly, since the main body of the alarm is connected and fixed to the fixed plate through a damper, when the train enters or leaves the station, the vertical vibration generated by it will be dissipated by the damper, thereby significantly reducing the vibration amplitude of the main body of the alarm and reducing the risk of damage to the internal components of the alarm.

[0016] Secondly, when a train enters or leaves a station, the horizontal vibration energy it generates is relatively small. Therefore, when the main body of the alarm vibrates, the buffer pad undergoes reversible deformation under pressure, converting the vibration kinetic energy into elastic potential energy, thus dissipating the vibration energy and reducing the risk of damage to the main body of the alarm from horizontal vibration.

[0032] like Figures 1 to 7 As shown, a railway station train entry and exit safety early warning device includes an alarm body 1. An upper connecting plate 3 is fixedly connected to the upper end of the back of the alarm body 1. A fixing plate 2 is provided on the back of the alarm body 1. An inverted U-shaped groove is opened on the fixing plate 2. A lower connecting plate 10 is slidably connected to the lower end of the fixing plate 2. Dampers 6 are installed at both ends of the top of the lower connecting plate 10. The upper end of the damper 6 is installed with the upper connecting plate 3. A buffer elastic member 9 is sleeved on the outside of the damper 6. The upper end of the buffer elastic member 9 is fixedly connected to the upper end of the damper 6, and the lower end of the buffer elastic member 9 is fixedly connected to the lower connecting plate 10.

[0033] The railway station train entry and exit safety warning device of this utility model has an alarm body 1 connected and fixed to a fixed plate 2 via an upper connecting plate 3 and a damper 6. Therefore, the vertical vibration generated when the train enters or leaves the station will be dissipated by the damper 6, thereby significantly reducing the vertical vibration amplitude of the alarm body 1 and reducing the risk of damage to the internal components of the alarm body 1. At the same time, the buffer elastic element 9 helps the damper 6 to return to its original length after vibration reduction, so that the damper 6 can continue to play the role of vibration reduction for the alarm body 1. In addition, since the alarm body 1 and the damper 6 in this utility model are existing mature products, they will not be described in detail here.

[0034] In some embodiments, both ends of the upper connecting plate 3 are provided with upper connecting grooves 4, and an upper connecting block 7 is slidably connected inside the upper connecting groove 4. The upper connecting block 7 is fixedly connected to the damper 6. An upper horizontal slot 12 is provided in the middle of the upper connecting plate 3. An upper horizontal insertion rod 13 is slidably connected inside the upper horizontal slot 12. The upper horizontal insertion rod 13 matches the upper connecting block 7. Both sides of the upper end of the fixing plate 2 are provided with end connecting grooves 19 that match the upper horizontal insertion rod 13. Buffer pads 5 are fixedly connected to the inner walls of the upper connecting groove 4 and the end connecting groove 19.

[0035] In some embodiments, a baffle 14 is fixedly connected to one end of the upper horizontal insertion rod 13, and a gripping plate 15 is fixedly connected to the side of the baffle 14 away from the fixed plate 2. A slot 16 is opened at the end of the upper horizontal insertion rod 13 away from the baffle 14. A stop block 17 is slidably connected inside the slot 16. Elastic blocks 18 are fixedly connected to both sides of the bottom of the stop block 17, and the elastic blocks 18 match the upper horizontal insertion rod 13.

[0036] In some embodiments, both ends of the lower connecting plate 10 are provided with lower connecting grooves 11, and a lower connecting block 8 is slidably connected inside the lower connecting groove 11. The lower connecting block 8 is fixedly connected to the bottom of the damper 6. A lower horizontal slot 20 is provided at the upper end of the lower connecting plate 10. A lower horizontal insert rod 21 that matches the lower connecting block 8 is slidably connected inside the lower horizontal slot 20. An end plate 22 is fixedly connected to one end of the lower horizontal insert rod 21. A gripping groove 23 is provided on the side of the end plate 22 away from the lower horizontal insert rod 21.

[0037] Furthermore, damper 6 may be damaged during long-term use, requiring replacement and repair. To replace damper 6, first move the elastic locking block 18 away from the upper horizontal insert rod 13, then remove the stop block 17 from above the upper horizontal insert rod 13. Next, pull the upper horizontal insert rod 13 out from one side of the fixing plate 2. Then, remove the lower connecting plate 10 from the bottom of the fixing plate 2 and pull the lower horizontal insert rod 21 out from the lower connecting plate 10. This allows the damper 6 to be removed. Then, the bottom of the new damper 6... Insert the end connecting block 8 into the lower connecting groove 11, then insert the lower horizontal insert rod 21 into the lower horizontal slot 20. Next, move the alarm body 1 so that the upper connecting plate 3 is at the upper end of the inverted U-shaped slot of the fixing plate 2. Then, reinsert the lower connecting plate 10 into the fixing plate 2 until the upper connecting block 7 at the top of the new damper 6 is inserted into the upper connecting groove 4. Then, insert the upper horizontal insert rod 13 into the upper horizontal slot 12. Finally, insert the stop block 17 into the slot 16 so that the elastic block 18 is locked in the upper horizontal insert rod 13. The whole replacement process is relatively simple and convenient and easy to operate.

[0038] In some embodiments, both ends of the bottom of the lower connecting plate 10 are slidably connected to a slide plate 24, and the bottom of the fixing plate 2 is provided with a groove 26 that matches the slide plate 24.

[0039] Furthermore, after the lower connecting plate 10 is inserted into the fixed plate 2, the sliding plate 24 can be inserted into the sliding groove 26 to restrict and fix the lower connecting plate 10, preventing the lower connecting plate 10 from detaching from the fixed plate 2.

[0040] In some embodiments, a magnetic block 27 is provided at the top of the slide plate 24 away from the lower connecting plate 10, and the magnetic block 27 is fixedly connected to the slide plate 24.

[0041] Furthermore, the slide plate 24 is fixed to the fixed plate 2 by magnetic block 27, making it difficult for the slide plate 24 to move on its own.

[0042] In some embodiments, the end of the slide plate 24 is trapezoidal, and a push block 25 is fixedly connected to the bottom of the slide plate 24.

[0043] Furthermore, the trapezoidal slide 24 has a better limiting effect, and pushing the slide 24 by the push block 25 is more effortless and convenient.

[0044] It is worth noting that: the buffer pad 5 can be made of rubber or silicone or other materials that can effectively absorb low-frequency vibrations. The buffer elastic element 9 is preferably made of stainless steel or piano wire, which has a high fatigue limit and is suitable for long-term reciprocating motion. Its surface is nickel-plated or coated to have strong corrosion resistance. The specific elastic force value should be changed according to the needs of the actual application. The magnetic block 27 can be made of neodymium iron boron magnet.

[0045] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
