This device is mainly used to monitor the current and voltage signals in the track circuit, promptly detect short - circuit faults, and issue early warning signals to ensure the safe operation of rail transit. When abnormal signals such as a sudden increase in current or abnormal voltage fluctuations are detected, the detection circuit board will immediately transmit the signals to the main control circuit board. The main control circuit board analyzes these signals, confirms the type and location of the fault, and activates the early warning system to issue an alarm through the warning light and buzzer, reminding maintenance personnel to conduct inspections and repairs.
[0003] Currently, there are some defects in the track circuit short - circuit detection and early warning device. The device usually does not have a maintenance - assisting device with automatic lighting, resulting in the need for maintenance personnel to carry additional lighting tools for operation at night or in a dark environment. When the overall control system of the existing device fails, it usually cannot provide backup power support, resulting in the inability of auxiliary devices such as LED light strips to continue working. This situation is particularly disadvantageous during emergency maintenance, which may cause maintenance personnel to fail to promptly detect and handle faults, delay the troubleshooting time, and increase the safety risks of the track system.
[0004] Therefore, a track circuit short - circuit detection and early warning device is needed to solve the above - mentioned technical deficiencies. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Embodiment 1: Please refer to Figures 1-4, An orbit circuit short - circuit detection and early warning device, including a housing 1 and an installation groove 14. A main control circuit board 13 is installed inside the housing 1. A panel 2 is arranged at the front end of the housing 1. The bottom end of the housing 1 is fixedly connected with a cavity 4. A battery assembly 9 is arranged inside the cavity 4, and the battery assembly 9 is fixed inside the cavity 4. A through - slot 8 is opened at the connection between the housing 1 and the cavity 4. An LED light strip 16 is installed on the inner wall of the through - slot 8 close to the housing 1 side. A micro - switch 10 is installed on one side of the bottom end of the inner wall of the housing 1. Two groups of antennas 15 are arranged at the top of the housing 1. The housing 1 is wirelessly connected to the railway control center through the antennas 15. Two groups of connecting wires 11 are connected to the left side of the housing 1. The housing 1 is connected to the orbit circuit through the connecting wires 11. A display screen and control buttons 18 are arranged at the front end of the panel 2. A buzzer, control buttons, voltage and current indicator lights are arranged at the display screen and control buttons 18;
[0025] Specifically, as Figure 1 , Figure 2 and Figure 3 shown, the housing 1 is provided with an opening - cover lighting mechanism inside the cavity 4 at the bottom. When the maintenance personnel horizontally pull out the panel 2 to the right to open the inside of the housing 1, the contact spring of the panel 2 and the micro - switch 10 is released. The micro - switch 10 sends a signal to the main control circuit board 13, and the main control circuit board 13 instructs the LED light strip 16 to light up, emitting light upward from the through - slot 8. So that in case of a circuit failure at night, it can automatically light up to assist in maintenance in the absence of light. When closing the cover, the panel 2 presses the contact spring of the micro - switch 10, then the light is automatically turned off. The micro - switch 10 is electrically connected to the battery assembly 9 inside the cavity 4. At the same time, the battery assembly 9 provides a backup power supply. Even in the case of the overall control system failure, the LED light strip 16 can still continue to illuminate, ensuring the smooth progress of emergency maintenance, and solving the problem of insufficient light during equipment maintenance at night or in the absence of light.
[0026] Embodiment 2: Two groups of heat - dissipation slots 6 are opened at the bottom end of the cavity 4. One group of negative - pressure fans 5 is fixed at each position of the heat - dissipation slots 6 of the cavity 4. A filter screen 7 is arranged above the negative - pressure fans 5. Two groups of insertion rods 17 are arranged on both sides of the filter screen 7. The filter screen 7 is horizontally inserted at the insertion rods 17;
[0027] Specifically, as Figure 1 and Figure 3 shown, two groups of negative - pressure fans 5 are arranged inside the cavity 4. The heat generated by the long - term operation inside the housing 1 is sucked by the negative - pressure fans 5 from the through - slot 8 and blown towards the heat - dissipation slots 6, preventing equipment failures caused by overheating and achieving efficient heat exchange. The use of the filter screen 7 can not only prevent dust from entering the equipment, but also protect the fans and other electronic components from the influence of dust, ensuring the twenty - four - hour early - warning operation of the device.
[0028] Embodiment 3: An installation groove 14 is provided at the front side edge of the inner wall of the housing 1. The panel 2 is inserted into the installation groove 14. Two groups of elastic buckles 3 are installed on the right side of the panel 2. Two positioning holes 12 are welded on the left side inner wall of the housing 1. Grooves matching the positioning holes 12 are provided at the corresponding positions on the left side of the panel 2.
[0029] Specifically, as Figure 1 and Figure 4 shown, the installation groove 14 in the housing 1 serves as a limiting member for the panel 2 to ensure smooth opening and closing of the panel 2. When opening the cover, open the elastic buckle 3 to release the buckling between the panel 2 and the housing 1, and then move the panel 2 to the right. When closing the cover, the positioning hole 12 is fitted with the groove of the panel 2 in place, and then the elastic buckle 3 is buckled tightly to the housing 1 to complete the closing of the cover, realizing quick opening and closing for maintenance. Without tools, the internal situation of the device can be quickly checked.
[0030] Working principle: The detection circuit board in the housing 1 continuously monitors the current and voltage signals in the track circuit. Once abnormal signals are detected, such as a sudden increase in current or abnormal voltage fluctuation, the detection circuit board will immediately send a signal to the main control circuit board 13. The main control circuit board 13 analyzes these signals to confirm whether there is a short-circuit fault. When a short-circuit fault is confirmed, the main control circuit board 13 activates the warning system, lights up the warning light and activates the buzzer to send out an alarm signal to remind the maintenance personnel to check and repair. For the convenience of maintenance at night or in low-light environments, when the maintenance personnel horizontally pull out the panel 2 to the right to open the housing 1, the contact spring of the micro switch 10 is released from the panel 2. The micro switch 10 sends a signal to the main control circuit board 13. The main control circuit board 13 instructs the LED light strip 16 to light up, emitting light upward from the through groove 8 to illuminate the internal structure for convenient maintenance. Inside the housing 1, the negative pressure fan 5 sucks the heat inside the housing 1, filters the dust through the filter screen 7, and then discharges the heat through the heat dissipation slot 6 to ensure that the device maintains a stable temperature during 24-hour operation and prevent equipment failures caused by overheating.
