Description

Technical Field

[0001] This utility model relates to the field of high-speed railway catenary technology, specifically a safety status monitoring device for high-speed railway catenary. Background Technology

[0002] The overhead contact system of high-speed railways is a special type of power transmission line that is erected above the railway line to supply power to electric locomotives. It consists of several parts, including contact suspension, support devices, positioning devices, pillars, and foundations. It can transmit electrical energy obtained from traction substations to electric locomotives. However, bird-related accidents in high-speed railway contact systems are increasing daily. Flocks of birds not only nest and breed on the contact system, but also indiscriminately defecate, causing contamination of insulators. This greatly increases the probability of accidents such as phase-to-phase short circuits and flashovers, making it difficult to maintain a safe condition for the contact system and threatening the safe operation of high-speed railways.

[0003] Existing high-speed railway catenary safety status monitoring devices typically rely on manual inspections along the route to detect bird damage. Staff identify severely bird-infested areas based on inspection data and then set up bird-repelling devices in these areas to drive away flocks of birds. However, this monitoring method is cumbersome to implement, cannot accurately pinpoint the location of birds, affecting the actual deterrent effect of the bird-repelling devices, and cannot promptly transmit data on the damage to the high-speed railway catenary to staff, impacting their judgment of the catenary's condition. This is detrimental to the monitoring work of the high-speed railway catenary. Summary of the Invention

One end of each fastening bolt 24 extends through to the outside of the second arc-shaped clip 23 and is screwed with a locking nut 25. Figure 1 , Figure 2 As shown, by setting the first arc-shaped clip 22 and the second arc-shaped clip 23, and cooperating with the locking nut 25 as a fastener, this utility model can be easily installed on the outside of the contact wire support, so that the bird deterrent component 8 is at a suitable height.

[0028] The monitoring component 16 includes a detection radar 161 fixed to one end of the boss 10, and a processor 162 fixedly mounted on the outside of the integrated motherboard 12. The detection radar 161 is connected to the processor 162 via a data cable, and the processor 162 is connected to the integrated motherboard 12 via a data cable. Figure 3 , Figure 4 As shown, the detection radar 161 can detect the activity of bird flocks on the overhead contact line of the high-speed railway in real time. Then, the processor 162 processes the data from the detection radar 161 to determine the location of the bird flock. The integrated motherboard 12 then controls the first drive component 9 and the second drive component 15 to adjust the angle and orientation of the bird deterrent component 8 so that it faces the bird flock. This targeted approach effectively drives away the bird flock and improves the bird deterrent effect.

[0029] The wireless component 19 includes a wireless transceiver 191 fixed to the top of the pole 18, and a timer 192 fixedly mounted on the outside of the integrated motherboard 12. Both the timer 192 and the wireless transceiver 191 are connected to the terminals of the integrated motherboard 12 via data cables. Figure 3 , Figure 4 As shown, in actual use, the integrated motherboard 12 controls the timer 192 to start together with the bird deterrent component 8. When the timer 192 reaches its preset threshold, it will send a signal to the integrated motherboard 12. This indicates that the bird damage in the area is serious and requires manual intervention, or that the bird deterrent component 8 has malfunctioned and requires manual inspection and maintenance. The integrated motherboard 12 will control the wireless transceiver 191 to send data to the nearest locomotive depot, so that the locomotive depot staff can understand the safety status of the high-speed railway catenary and go out to investigate and eliminate the threat.

[0030] Working principle: First, the installer 2 facilitates the installation of this utility model on the outside of the overhead contact line support, thus placing the bird deterrent component 8 at a suitable height. Then, the monitoring component 16 can detect the activity of bird flocks on the high-speed railway overhead contact line within the range in real time, thereby determining the location of the bird flock. After determining the location of the bird flock, the first drive component 9 and the second drive component 15 can quickly adjust the angle and orientation of the bird deterrent component 8 according to the actual location of the bird flock, thus specifically driving away the bird flock and effectively improving the bird deterrence effect. At the same time, the wireless component 19 can transmit data to the nearest locomotive depot when the monitoring component 16 detects serious bird damage to the high-speed railway overhead contact line within the range. This allows the locomotive depot staff to understand the safety status of the high-speed railway overhead contact line and dispatch personnel to investigate and eliminate the threat, realizing the monitoring of the safety status of the high-speed railway overhead contact line.
