Description

Technical Field

[0001] This invention relates to the field of high-speed railway catenary technology, and more specifically, to a special intelligent grounding wire and monitoring system for high-speed railway catenary. Background Technology

[0002] The overhead contact system of high-speed railway refers to 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 plays a vital role in the safe and stable operation of high-speed trains. During the maintenance of the contact system, installing grounding wires is an important measure to ensure the safety of personnel. In order to achieve comprehensive monitoring of the grounding wire during its use, an intelligent grounding wire and its control system have been designed. This system can accurately monitor the installation position of the grounding wire and whether the grounding wire is reliably suspended on the contact system, while realizing the full life cycle control of the grounding wire.

[0003] According to patent document CN108425932A, a self-locking device for high-speed railway contact networks is disclosed, comprising a main bolt, a main nut, a washer, and a locking nut. The main bolt has a first thread and a second thread sequentially arranged from the outside to the inside on the side wall of the end furthest from the bolt head. The first and second threads rotate in opposite directions. The locking nut, washer, and main nut are sequentially fitted onto the main bolt from the outside to the inside. The locking nut and main nut are threadedly connected to the first and second threads, respectively. The washer abuts against the locking nut and main nut on both sides, with spikes evenly distributed on the side abutting the main nut. The purpose of this invention is to provide a special spiked self-locking fastening device for high-speed railway contact networks. It uses a ratchet-toothed locking nut with the opposite rotation direction to the main nut and a spiked washer to jointly achieve anti-loosening locking of the main nut. The main nut and locking nut adopt a "reverse-locking" structure with opposite threads, which can prevent the main nut from loosening in case the washer mechanism fails.

[0004] When a high-speed rail overhead contact system malfunctions, it is usually necessary to safely release the high-voltage electricity through a grounding wire to ensure the safety of maintenance personnel and the smooth progress of maintenance work. However, under normal circumstances, the grounding wire connected to the high-speed rail overhead contact system is directly connected to the ground, and there is no device in the grounding wire section to stabilize its tilt amplitude and angle. This may cause the grounding wire to sway or shift due to external factors such as wind and vibration during the release of high-voltage electricity, thereby affecting the grounding effect and even potentially damaging the grounding wire itself or the overhead contact system. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, this invention provides a dedicated intelligent grounding wire and monitoring system for high-speed railway contact networks. The technical problem to be solved by this invention is that the grounding wire connected to the high-speed railway contact network is directly connected to the ground, and there is no device for stabilizing its tilt amplitude and angle within the grounding wire section. This may cause the grounding wire to sway or deviate due to external factors such as wind and vibration during the release of high-voltage electricity, thereby affecting the grounding effect and potentially damaging the grounding wire itself or the contact network.

[0009] As a further aspect of the present invention: both positioning components include sliders, the rear sides of both sliders are slidably connected to the outer walls of two guide rods, L-shaped blocks are fixedly connected to the outer sides of both sliders, sleeves are fixedly connected to the inner walls of both sliders and the inner walls of the two L-shaped blocks, the outer walls of the two sleeves that are far apart from each other are slidably connected to the inner walls of two convex guide blocks, and the inner walls of the two sleeves are fitted onto both sides of the outer wall of the grounding wire.

[0010] As a further embodiment of the present invention: L-shaped sliding rods are fixedly connected to the left and right sides of the two sliders, and the rear sides of the two sets of L-shaped sliding rods away from the sliders are slidably connected to the top and bottom of the inner wall of the guide groove opened on the front side of the two side plates. Rotating rod connecting blocks are fixedly connected to the front sides of the two sliders, and rotating rods are rotatably connected to the left and right sides of the two rotating rod connecting blocks. V-shaped rotating blocks are rotatably connected to the inner sides of the top two rotating rods and the bottom two rotating rods.

[0011] As a further embodiment of the present invention: the middle part of the outer wall of the two V-shaped rotating blocks is rotatably connected to the inner side of the two top L-shaped side plates and the two bottom L-shaped side plates, the inner wall of the outer side of the two V-shaped rotating blocks is fixedly connected to a positioning connecting block, and the rear side of the two positioning connecting blocks is fixedly connected to a C-shaped positioning block.

[0012] As a further embodiment of the present invention: the inner sides of the left and right sets of side upright connecting rods are fixedly connected to the top and bottom of the outer sides of the two side plates, the top and bottom of the two side uprights are rotatably connected to bidirectional hinge blocks, the outer sides of the left and right sets of bidirectional hinge blocks are rotatably connected to arc-shaped rod shaft blocks, and the outer sides of the arc-shaped rod shaft blocks on both sides are fixedly connected to arc-shaped rods.

[0013] As a further embodiment of the present invention: the rear sides of the left and right sets of arc-shaped rods are rotatably connected to a second bidirectional hinge block, the inner sides of the left and right sets of the second bidirectional hinge blocks are rotatably connected to a push block, and the inner sides of the left and right sets of push blocks are rotatably connected to the rear sides of the outer sides of the upper and lower sets of L-shaped slide rods.

[0014] As a further embodiment of the present invention: an L-shaped warning plate is fixedly connected to the front side of each of the left and right sets of arc-shaped rods, and a warning light is fixedly connected to the middle of the front side of each of the left and right sets of L-shaped warning plates.

[0015] In addition, the present invention also relates to a monitoring system for a special intelligent grounding wire for high-speed railway catenary, comprising the following steps: Step 1: Monitor the operating status of the high-speed railway catenary in real time. By installing various sensors at key parts of the catenary, continuously collect parameter information such as current, voltage, and temperature of the catenary, and transmit this data to the data analysis module of the monitoring system in real time. Step 2: The data analysis module analyzes and processes the received real-time data, compares the collected parameters with the preset normal operating parameter range, and determines whether the contact network has a fault or potential risk. If the parameters exceed the normal range, it is determined that the contact network may have a fault. Step 3: When the data analysis module determines that a fault has occurred in the overhead contact line, it immediately triggers the emergency response mechanism, sending a start command to the system's actuators to activate the bidirectional electric actuator. Step 4: The bidirectional electric push rod pushes the convex connecting block forward, which in turn moves the two columnar connecting rods and the middle connecting block forward together, causing the sliders in the two positioning components to slide on the guide rods, while the L-shaped slide rod slides in the guide groove, ensuring that the entire movement process is smooth and accurate. Step 5: As the slider moves, the rotating rod connecting block drives the rotating rod to rotate, causing the V-shaped rotating block to rotate inside the L-shaped side plate. This allows the positioning connecting block and the C-shaped positioning block to gradually approach and adhere to the grounding wire, ensuring that the angle between the grounding wire and the contact network tends to be perpendicular, preventing poor contact or detachment of the grounding wire due to angle deviation. Step Six: While the positioning connecting block and the C-shaped positioning block support the outer wall of the grounding wire on both sides, the two sleeves slide outward on the outer wall of the grounding wire to expand and protect the raised outer wall of the grounding wire. Step 7: As the L-shaped sliding rod moves, the push block pushes the second bidirectional hinge block, causing the arc-shaped rod to rotate around the arc-shaped rod axis block, thereby unfolding the L-shaped warning plate and illuminating the warning light to send a clear warning signal to the surrounding personnel. Step 8: The monitoring system continuously tracks the fault handling status of the overhead contact line. After the fault is resolved, it receives a manual reset command or, based on the system's automatic judgment that the fault has been resolved, controls the bidirectional electric push rod to move in the reverse direction, so that each component returns to its initial state, and at the same time turns off the warning light.

[0016] The beneficial effects of this invention are as follows: This invention, by incorporating a grounding wire connector, a grounding wire, and a warning mechanism, enables rapid response and precise handling of faults in the high-speed railway overhead contact system. Through intelligent mechanical structure design, it ensures a stable and reliable connection between the grounding wire and the contact system, effectively preventing safety accidents that may be caused by poor grounding. Furthermore, the system integrates a warning function, promptly alerting surrounding personnel when a fault occurs, improving the timeliness and safety of fault handling. Overall, this invention provides an efficient and intelligent solution for the maintenance and repair of high-speed railway overhead contact systems. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, the present invention provides a special intelligent grounding wire for high-speed rail contact network, including a grounding wire connector 1, a grounding wire 2 provided on the inner wall of the grounding wire connector 1, and warning mechanisms 3 fixedly connected to both the left and right sides of the grounding wire connector 1.

[0021] like Figure 2-8As shown, the grounding wire connector 1 includes a connecting plate 11. Positioning components 12 are provided at the top and bottom of the front side of the connecting plate 11. The connecting plate 11 includes a connecting upright plate 111.

Both sides of the front of the central connecting block 117 are fixedly connected with columnar connecting rods 119. The front ends of the two columnar connecting rods 119 are fixedly connected with convex connecting blocks 1110. The middle of the front side of the convex connecting block 1110 is fixedly connected with a bidirectional electric push rod 1111. The middle of the front side of the central connecting block 117 is fixedly connected with a central sleeve 118. Both positioning components 12 include sliders 121. The rear sides of the two sliders 121 are slidably connected to the outer walls of the two guide rods 116. The outer sides of the two sliders 121 are fixedly connected with L-shaped blocks 122. The inner walls of the two sliders 121 and the inner walls of the two L-shaped blocks 122 are fixedly connected with sleeves 123. The outer walls of the two sleeves 123 that are far apart from each other are slidably connected to the inner sides of the two convex guide blocks 114. The inner walls of the two sleeves 123 are fitted onto both sides of the outer wall of the grounding wire 2. L-shaped sliding rods 128 are fixedly connected to the left and right sides of the two sliders 121. The rear sides of the two sets of L-shaped sliding rods 128, away from the sliders 121, are slidably connected to the top and bottom of the inner walls of the guide grooves 113 opened on the front sides of the two side plates 112. Rotating rod connecting blocks 124 are fixedly connected to the front sides of the two sliders 121. Rotating rods 125 are rotatably connected to the left and right sides of the two rotating rod connecting blocks 124. V-shaped rotating blocks 126 are rotatably connected to the inner sides of the top two rotating rods 125 and the bottom two rotating rods 125. The middle of the outer walls of the two V-shaped rotating blocks 126 are rotatably connected to the inner sides of the top two L-shaped side plates 115 and the bottom two L-shaped side plates 115. Each V-shaped rotating block 126 has a positioning connecting block 127 fixedly connected to its outer inner wall. Each of the two positioning connecting blocks 127 has a C-shaped positioning block 129 fixedly connected to its rear side. The warning mechanism 3 includes two side uprights 31. The top and bottom of the outer sides of each side upright 31 are fixedly connected to side upright connecting rods 32. The inner sides of the left and right sets of side upright connecting rods 32 are fixedly connected to the top and bottom of the outer sides of the two side plates 112. The top and bottom of each side upright 31 are rotatably connected to bidirectional hinge blocks 33. The outer sides of each of the left and right sets of bidirectional hinge blocks 33 are rotatably connected to arc-shaped rod shaft blocks 34. The outer sides of the left and right arc-shaped rod shaft blocks 34 are fixedly connected to arc-shaped rods 35. The rear sides of each of the left and right sets of arc-shaped rods 35 are rotatably connected to second bidirectional hinge blocks 36.Both sets of left and right second bidirectional hinge blocks 36 have push blocks 37 rotatably connected to their inner sides. The inner sides of both sets of push blocks 37 are rotatably connected to the rear sides of the outer sides of the upper and lower sets of L-shaped slide rods 128. L-shaped warning plates 38 are fixedly connected to the front sides of both sets of left and right arc-shaped rods 35. Warning lights 39 are fixedly connected to the center of the front sides of both sets of left and right L-shaped warning plates 38. When a high-speed rail overhead contact system malfunctions, the system will immediately trigger the preset emergency response procedure. As one of the core execution components, the bidirectional electric push rod 1111 starts first, precisely pushing the convex connecting block 1110 forward. This action is transmitted to the two columnar connecting rods 119, and further drives the middle connecting block 117 to move forward in coordination, thereby causing the sliders 121 in the two positioning components 12 to slide smoothly along the guide rod 116. At the same time, the L-shaped slide rod 128 performs constrained movement in the guide groove 113, effectively ensuring the stability and trajectory accuracy of the entire transmission process. As the slider 121 continues to move, the rotating rod connecting block 124 pushes the rotating rod 125 to rotate, which in turn drives the V-shaped rotating block 126 to rotate inside the L-shaped side plate 115. This mechanical action causes the positioning connecting block 127 and the C-shaped positioning block 129 to gradually approach the grounding wire 2, eventually achieving a tight fit. This also causes the angle between the grounding wire and the contact network to be adjusted to a near-vertical state. This adjustment effectively avoids poor grounding or accidental detachment due to angle deviation, greatly improving the reliability of the connection. While the positioning structure is in place, the two sleeves 123 slide outward synchronously along the outer wall of the grounding wire, forming an expanded protective structure. This not only prevents the grounding wire from being damaged by external foreign objects, but also further enhances its integrity and safety during fault handling. On the other hand, as the L-shaped slide bar 128 moves, the push block 37 begins to push the second bidirectional hinge block 36, causing the arc-shaped rod 35 to rotate around the arc-shaped rod axis block 34. This movement ultimately drives the L-shaped warning plate 38 to unfold, and at the same time triggers the warning light 39 to light up, forming a clearly visible warning signal. This visual warning mechanism can effectively remind surrounding personnel to pay attention to the high-voltage danger area and avoid accidental approach, thereby ensuring the safety of maintenance personnel and equipment. The entire system relies on high-precision coordination and intelligent control logic among multiple components to achieve rapid and accurate response and multiple safety protections in emergency situations where the high-speed rail catenary malfunctions, significantly improving the safety and reliability of high-speed rail operation.

[0022] In addition, the present invention also relates to a monitoring system for a special intelligent grounding wire for high-speed railway catenary, comprising the following steps: Step 1: Monitor the operation status of the high-speed railway catenary in real time. By installing various sensors such as current sensors, voltage sensors, and temperature sensors at key parts of the catenary, continuously collect parameter information such as current, voltage, and temperature of the catenary, and transmit this data to the data analysis module of the monitoring system in real time. Step 2: The data analysis module analyzes and processes the received real-time data, compares the collected parameters with the preset normal operating parameter range, and determines whether the contact network has a fault or potential risk. If the parameters exceed the normal range, it is determined that the contact network may have a fault. Step 3: When the data analysis module determines that a fault has occurred in the overhead contact line, it immediately triggers the emergency response mechanism, sending a start command to the system's actuator to activate the bidirectional electric actuator 1111. Step 4: The bidirectional electric push rod 1111 pushes the convex connecting block 1110 forward, which drives the two columnar connecting rods 119 and the middle connecting block 117 to move forward together, causing the sliders 121 in the two positioning components 12 to slide on the guide rod 116, while the L-shaped slide rod 128 slides in the guide groove 113, ensuring that the entire movement process is smooth and accurate. Step 5: As the slider 121 moves, the rotating rod connecting block 124 drives the rotating rod 125 to rotate, causing the V-shaped rotating block 126 to rotate inside the L-shaped side plate 115, so that the positioning connecting block 127 and the C-shaped positioning block 129 gradually approach and stick to the grounding wire 2, ensuring that the angle between the grounding wire and the contact network tends to be perpendicular, and preventing the grounding wire from having poor contact or falling off due to angle deviation; Step 6: While the positioning connection block 127 and the C-shaped positioning block 129 support the outer wall of the grounding wire on both sides, the two sleeves 123 slide outward on the outer wall of the grounding wire to expand and protect the raised outer wall of the grounding wire. Step 7: As the L-shaped slide bar 128 moves, the push block 37 pushes the second bidirectional hinge block 36, causing the arc-shaped rod 35 to rotate around the arc-shaped rod axis block 34, thereby allowing the L-shaped warning plate 38 to unfold and the warning light 39 to light up, sending a clear warning signal to the surrounding personnel. Step 8: The monitoring system continuously tracks the fault handling status of the overhead contact line. After the fault is resolved, it receives a manual reset command or, based on the system's automatic judgment that the fault has been resolved, controls the bidirectional electric push rod 1111 to move in the reverse direction, so that each component returns to its initial state, and at the same time turns off the warning light 39.

[0023] Working principle of this invention: The operator securely installs the entire device around the insulator on the insulating arm of the grounding wire connector 1 at the designated location on the contact network using standard screws and nuts. This ensures a tight fit between the grounding wire connector 1 and the insulator on the insulating arm, with no loosening at any connection point, providing a reliable foundation for subsequent grounding operations. When a fault occurs in the high-speed rail contact network, the system quickly activates the emergency response mechanism. The bidirectional electric push rod 1111 begins operation, pushing the convex connecting block 1110 forward, which in turn moves the two columnar connecting rods 119 and the central connecting block 117 forward. This action causes the sliders 121 in the two positioning components 12 to slide on the guide rod 116, while the L-shaped sliding rod 128 also slides within the guide groove 113, ensuring the smoothness and accuracy of the entire movement process. As the slider 121 moves, the rotating rod connecting block 124 drives the rotating rod 125 to rotate, which in turn causes the V-shaped rotating block 126 to rotate inside the L-shaped side plate 115. This rotation causes the positioning connecting block 127 and the C-shaped positioning block 129 to gradually approach and adhere to the grounding wire 2, ensuring that the angle between the grounding wire and the contact network tends to be perpendicular, preventing poor contact or detachment of the grounding wire due to angle deviation. While the positioning connecting block 127 and the C-shaped positioning block 129 support the outer wall of the grounding wire on both sides, the two sleeves 123 slide outward on the outer wall of the grounding wire, causing the two sleeves 123 to expand and protect the raised outer wall of the grounding wire. At the same time, as the L-shaped sliding rod 128 moves, the push block 37 pushes the second bidirectional hinge block 36, which in turn causes the arc-shaped rod 35 to rotate around the arc-shaped rod axis block 34. This rotation causes the L-shaped warning plate 38 to unfold and the warning light 39 to light up, sending a clear warning signal to the surrounding personnel.

The inner sides of the left and right sets of push blocks (37) are rotatably connected to the rear sides of the outer sides of the upper and lower sets of L-shaped slide rods (128).

9. A smart grounding wire for high-speed railway contact network according to claim 8, characterized in that: Both sets of arc-shaped rods (35) are fixedly connected to the front side of an L-shaped warning plate (38), and both sets of L-shaped warning plates (38) are fixedly connected to the middle of the front side of a warning light (39).

10. A special intelligent grounding wire for high-speed railway catenary, and a monitoring system for a special intelligent grounding wire for high-speed railway catenary according to any one of claims 1-9, characterized in that: Includes the following steps: Step 1: Monitor the operating status of the high-speed railway catenary in real time. By installing various sensors at key parts of the catenary, continuously collect parameter information such as current, voltage, and temperature of the catenary, and transmit this data to the data analysis module of the monitoring system in real time. Step 2: The data analysis module analyzes and processes the received real-time data, compares the collected parameters with the preset normal operating parameter range, and determines whether the contact network has a fault or potential risk. If the parameters exceed the normal range, it is determined that the contact network may have a fault. Step 3: When the data analysis module determines that a fault has occurred in the overhead contact line, it sends a start command to the system's actuator, causing the bidirectional electric actuator (1111) to begin operation. Step 4: The bidirectional electric push rod (1111) pushes the convex connecting block (1110) forward, causing the two columnar connecting rods (119) and the middle connecting block (117) to move forward together, causing the sliders (121) in the two positioning components (12) to slide on the guide rod (116), while the L-shaped slide rod (128) slides in the guide groove (113), ensuring that the entire movement process is smooth and accurate; Step 5: As the slider (121) moves, the rotating rod connecting block (124) drives the rotating rod (125) to rotate, so that the V-shaped rotating block (126) rotates inside the L-shaped side plate (115), allowing the positioning connecting block (127) and the C-shaped positioning block (129) to gradually approach and adhere to the grounding wire (2), ensuring that the angle between the grounding wire and the contact network tends to be perpendicular, and preventing the grounding wire from having poor contact or falling off due to angle deviation; Step 6: While the positioning connecting block (127) and the C-type positioning block (129) support the outer wall of the grounding wire on both sides, the two sleeves (123) slide outward on the outer wall of the grounding wire to expand and protect the raised outer wall of the grounding wire. Step 7: As the L-shaped slide bar (128) moves, the push block (37) pushes the second bidirectional hinge block (36), causing the arc-shaped rod (35) to rotate around the arc-shaped rod axis block (34), thereby allowing the L-shaped warning plate (38) to unfold and the warning light (39) to light up, sending a clear warning signal to the surrounding personnel. Step 8: The monitoring system continuously tracks the fault handling status of the contact network. After the fault is resolved, it receives a manual reset command or controls the bidirectional electric push rod (1111) to move in the reverse direction based on the system's automatic judgment that the fault has been resolved, so that each component returns to its initial state and the warning light (39) is turned off.
