During maintenance, the entrances and exits of the depot are critical areas for personnel and equipment access, representing both a key focus and a challenge in management. Traditional security measures at depot entrances and exits primarily rely on static isolation facilities, such as guardrails and warning signs. However, these measures only provide basic visual cues and cannot effectively prevent personnel or equipment from accidentally entering. Furthermore, because the high-speed train maintenance depot is a high-risk working environment, if personnel forcibly cross the isolation area or equipment is misoperated and enters the maintenance area, it could lead to serious safety accidents.

[0003] To enhance safety, some high-speed train maintenance depots have introduced technologies such as video surveillance and electronic access control. However, these devices rely heavily on manual monitoring and backend analysis, lacking sufficient real-time performance and automation to fully meet the high-efficiency safety management needs of high-speed train maintenance depots. Furthermore, these systems lack physical isolation capabilities, limiting their effectiveness in accident prevention. In addition, existing technologies for managing the maintenance process largely depend on manual recording, resulting in scattered, incomplete, and difficult-to-trace data, hindering comprehensive control over the maintenance process.

[0004] Therefore, it is necessary to provide an alert device that can comprehensively provide physical isolation, protective monitoring, warning prompts, and data management functions. Utility Model Content

[0022] The embodiments described below are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0023] See Figures 1-3This embodiment provides a warning device for a high-speed train maintenance depot, installed at the entrance and exit of the depot. It includes a fixed base 10, a fixed rod 20, a traveling rod 30, a telescopic rod unit 40, at least one telescopic isolation belt 50, a detection sensor 60, a warning unit 70, a processor, and a management system 80. The fixed base 10 and the fixed rod 20 are fixedly connected by a connecting rod. The fixed base 10 is located on one side of the entrance and exit of the high-speed train maintenance depot, and the traveling rod 30 is located on the side of the fixed rod 20 away from the fixed base 10. The traveling rod 30 and... The telescopic pole unit 40 and the telescopic isolation belt 50 are connected between the fixed poles 20. The telescopic pole unit 40 is used to drive the walking pole 30 away from or towards the fixed pole 20. The detection sensor 60 is provided on the side of the walking pole 30 away from the fixed pole 20. The warning unit 70 is provided around the walking pole 30. The processor and the management system 80 are both provided on the fixed base 10. The processor is connected to the telescopic pole unit 40, the detection sensor 60, the warning unit 70, and the management system 80.

[0024] Preferably, the telescopic rod unit 40 includes an electric telescopic rod, which includes a drive unit connected to the processor. Specifically, the electric telescopic rod in this application includes a main body, a multi-stage telescopic rod body, and a drive unit for driving the multi-stage telescopic rod body to perform telescopic movements. The drive unit includes a geared motor, a telescopic isolation belt 50 steel belt, and a passive pressure roller installed in the main body. The output end of the geared motor is provided with an active pressure roller. One end of the telescopic isolation belt 50 steel belt is wound in a reel, and the other end is vertical and extends out of the main body and is fixedly connected to the upper end of the multi-stage telescopic rod. The reel is fixedly installed in the housing. The active pressure roller and the passive pressure roller are set at the same height. The active pressure roller and the passive pressure roller are respectively set on both sides of the vertical end of the telescopic isolation belt 50 steel belt and simultaneously press the telescopic isolation belt 50 steel belt. The telescopic isolation belt (50mm steel belt) is driven by a drive unit, which in turn drives the telescopic pole to extend and retract. Users only need to control the forward and reverse switches of the geared motor to automatically extend or retract the pole. It should be noted that an electric telescopic pole using a lead screw and nut in conjunction with a motor can also be used, but this will not be elaborated upon here.

[0025] Preferably, the telescopic isolation belt 50 comprises two telescopic isolation belts 50 disposed at different heights. In this application, the telescopic isolation belt 50 can be made of nylon rope or steel wire rope, etc. Preferably, one end of the telescopic isolation belt 50 is connected to the walking pole 30, and the other end of the telescopic isolation belt 50 is connected to a winding assembly inside the fixed pole 20. The winding assembly includes a rotating shaft, a torsion spring, a turntable, a limiting rod, a sliding groove, and a spring sheet. The outer surface of the rotating shaft is connected to the torsion spring, and both ends of the torsion spring are connected to the turntable. The limiting rod is disposed below the turntable, and the lower surface of the limiting rod is slidably connected to the sliding groove. When the telescopic rod unit 40 extends, it pulls out the telescopic isolation belt 50. The rollers make the telescopic isolation belt 50 extend more smoothly. The telescopic isolation belt 50 pulls the turntable to rotate, which in turn drives the torsion spring connected to it to rotate, causing the torsion spring to tighten. When it is necessary to retract, the torsion spring drives the turntable to return to its original position, retracting the telescopic isolation belt 50, thus realizing the extension and retraction of the telescopic isolation belt 50. As another preferred embodiment, the winding assembly is a winding motor. The telescopic isolation belt 50 is fixedly connected to the output end of the winding motor. The forward and reverse rotation of the winding motor realizes the unwinding and winding of the telescopic isolation belt 50.

[0026] Preferably, the detection sensor 60 is an infrared sensor or a millimeter-wave radar sensor. Using an infrared sensor or millimeter-wave radar sensor allows for rapid detection of the presence of personnel ahead. When personnel are detected, the sensor promptly sends a signal to the processor, which immediately controls the telescopic rod unit 40 to stop moving, effectively preventing collisions with personnel during device operation. This design not only improves the real-time performance and response speed of the detection but also further enhances the safety of the device, providing reliable protection for personnel and equipment operation at the entrance and exit of the EMU maintenance depot, and significantly reducing the risk of safety accidents. It should be noted that the processor in this application incorporates a known program to implement the above process, which will not be elaborated upon here.

[0027] Preferably, the warning unit 70 is an audible and visual warning unit 70. Using an audible and visual warning unit 70 as the warning unit allows for effective alerting of maintenance personnel to safety through both sound and light. When the equipment detects potential risks or abnormalities (such as high-voltage line energization / de-energization during maintenance, or entry / exit signals), the audible and visual warning unit 70 can promptly emit a bright flashing light signal and a warning sound, thereby attracting personnel's attention and preventing accidents.

[0028] Preferably, the management system 80 includes a touch-screen all-in-one computer. This touch-screen all-in-one computer enables intuitive interaction and convenient control of the equipment. It supports switching between manual and automatic modes, allowing users to choose the appropriate operating method based on actual needs. In manual mode, it flexibly controls the extension length of the telescopic unit or isolation belt to meet specific operational scenarios. Simultaneously, the management system 80 also features maintenance information input and query functions. Users can directly input relevant data or retrieve historical records on the touch-screen all-in-one computer, supporting precise management and subsequent traceability of the maintenance process. This design effectively improves the intelligence and practicality of the device, optimizing the overall management efficiency of the EMU maintenance depot.

[0029] Preferably, a pulley 100 is provided at the bottom of the traveling rod 30. The pulley 100 effectively reduces the frictional resistance of the traveling rod 30 during movement, ensuring its smooth and flexible operation. Driven by the telescopic rod unit 40, the pulley 100 assists the traveling rod 30 to move smoothly along a predetermined path, thereby improving the working efficiency and reliability of the device. Furthermore, the design of the pulley 100 reduces mechanical wear during device operation, extends the service life of the equipment, and lowers maintenance costs, providing technical support for the efficient and safe management of the entrance and exit of the EMU maintenance depot.

[0030] Preferably, the mounting base 10 is also provided with an emergency stop button 90, which can be pressed to immediately stop operation in case of an emergency. Preferably, the processor is a programmable logic controller with a built-in known program.

[0031] It should be noted that the management system 80 of this application can adjust the extension and retraction of the telescopic rod unit 40, ensuring flexible setup and real-time control of the isolation area. Furthermore, the management system 80 supports comprehensive collection and recording of relevant data during the maintenance process, including key data such as maintenance time, date, maintenance personnel identification information, maintenance start time, maintenance duration, and maintenance end time. Through these functions, the management system 80 can provide detailed digital support for the operational status of the EMU maintenance depot, facilitating subsequent data analysis and traceability, significantly improving the standardization, transparency, and safety of the maintenance process, while providing important decision-making basis for management personnel, effectively improving the overall management level and work efficiency of the EMU maintenance depot.

[0032] This utility model provides a warning device for EMU maintenance depots. Through the telescopic adjustment of the telescopic rod unit 40, the distance between the traveling rod 30 and the fixed rod 20 can be dynamically adjusted, allowing for flexible setting of isolation zones to meet the needs of different work scenarios. This achieves efficient and flexible physical isolation of the EMU maintenance depot. Secondly, the detection sensor 60 installed on the traveling rod 30 can monitor the presence of people in front in real time. When a person is detected, the telescopic rod unit 40 stops moving, effectively avoiding potential collisions with workers during operation and further improving safety. The warning unit 70 installed on the traveling rod 30 can remind maintenance personnel to pay attention to safety, reducing the risk of accidents. Simultaneously, the management system 80 controls the device's operating status and records and stores operational data, facilitating subsequent data analysis and traceability, and helping to improve the safety management level and work efficiency at the entrances and exits of the EMU maintenance depot. Therefore, this warning device for EMU maintenance depots effectively ensures the smooth progress of EMU maintenance operations through dynamic adjustment, real-time monitoring, safety prompts, and data management.

[0033] The above-disclosed embodiments are merely some preferred embodiments of the present utility model, and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model patent application shall still fall within the scope of the present utility model.
