Description

Technical Field

[0001] This invention relates to the field of high-voltage maintenance, and in particular to an intelligent anti-misoperation interlocking system and method for high-voltage maintenance grounding rods. Background Technology

[0002] 110kV overhead power lines are among the most commonly used high-voltage power lines in urban and rural power distribution networks in my country. They are responsible for transmitting electricity to industrial, commercial and residential users and are characterized by long transmission line mileage and numerous nodes.

[0003] To ensure the stable operation of 110kV distribution lines, regular inspections and maintenance are required. On-site maintenance and repair work must strictly adhere to standardized procedures for power outages, voltage testing, grounding, hanging warning signs, and installing barriers. This is primarily achieved through various monitoring terminals and the coordination of the person in charge of live-line work for on-site implementation and remote safety management. Currently, the main voltage testing and grounding protection tools have low levels of digitalization and intelligence, allowing for only relatively crude use and management. Existing grounding rod structures are also relatively simple, failing to establish mutual supervision with hooks, easily leading to problems such as hanging grounding wires while energized, omitting grounding rods during power supply, and false grounding. Therefore, a high-voltage maintenance grounding rod intelligent anti-misoperation interlocking system and method are proposed to address these issues. Summary of the Invention

[0004] To overcome the above deficiencies, this invention provides an intelligent anti-misoperation interlocking system and method for high-voltage maintenance grounding rods, aiming to improve the problem in the prior art that "the structure of the grounding rod in the prior art is relatively simple and cannot form mutual supervision with the hook".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent anti-misoperation interlocking system for high-voltage maintenance grounding rods, comprising:

[0006] A mounting device is mounted on the outside of a cable. The mounting device includes a housing, which is U-shaped. A cover plate is installed on the upper surface of the housing.

[0008] A copper wire is used to transmit current. One end of the copper wire is fixedly connected to the outer wall of the hook, and the other end of the copper wire is fixedly connected to the outer wall of the fixing frame.

[0009] A workstation for receiving signals, the workstation being connected to circuit board one via signal connection, and the workstation being connected to circuit board two via signal connection;

[0010] The grounding rod is installed on the front surface of the hook.

[0011] As a further description of the above technical solution:

[0012] The mounting device also includes an elastic element, which is installed at one end of the electromagnetic lock near the enclosure plate.

[0013] As a further description of the above technical solution:

[0014] The outer walls of the sealing plate and the hook are provided with protrusions, the left and right surfaces of the fixing sleeve are fixedly connected with sliders, and the inner wall of the housing is provided with a slide rail.

[0015] As a further description of the above technical solution:

[0016] The grounding device also includes a coil, which is installed on the inner wall of the housing, and the copper wire passes through the center of the coil.

[0017] As a further description of the above technical solution:

[0018] The locking assembly includes a locking wheel, which is rotatably connected to the inner wall of the housing. The movable clamp has a toothed groove at one end near the locking wheel, and the toothed groove meshes with the locking assembly.

[0019] As a further description of the above technical solution:

[0020] A ratchet is fixedly connected to the upper surface of the locking wheel, and a pawl is rotatably connected to the inner wall of the housing.

[0021] As a further description of the above technical solution:

[0022] The pawl is elastically connected to the inner wall of the housing by a spring.

[0023] As a further description of the above technical solution:

[0024] A motor is installed on the inner wall of the housing, and a cam is fixedly connected to the outer wall of the motor output shaft.

[0025] As a further description of the above technical solution:

[0026] A pressure block is mounted on the rear surface of the movable clamp.

[0027] As a further description of the above technical solution:

[0028] A method for using an intelligent anti-misoperation interlocking system for high-voltage maintenance grounding rods includes the following steps;

[0029] S1: Preparation steps: Before mounting the mounting device, the grounding device needs to be fixed to the grounding line or the outer wall of the grounding bracket. The specific method is to first attach the fixing bracket to the outer wall of the bracket, and then press the moving clamp to move the pressure block closer to the bracket. The pressure block will squeeze the outer wall of the bracket. In this way, the housing two can be fixed to the outer wall of the bracket with the help of the fixing bracket and the pressure block. Then the moving clamp can be released. When the moving clamp moves, it will drive the locking component to rotate. When the moving clamp is released, the pawl will be driven by the spring to engage with the inner wall of the ratchet. At this time, the locking wheel will be restricted from rotating in the opposite direction. In this way, the moving clamp will be restricted from moving away from the bracket. After the fixing bracket and the bracket are fixed, the grounding device can send a signal to the workstation through the second circuit board. The workstation will then send a signal to the first circuit board. The first circuit board will control the electromagnetic lock to unlock. Then the elastic component will push the fixing sleeve to move the protrusion away from the U-shaped recess of the housing one.

[0030] S2: Installation steps: After the mounting device is unlocked, it can be mounted on the outer wall of the cable. Then, the housing can be pushed to move the electromagnetic lock to re-fit onto the outer wall of the latch. In this way, the latch can be re-fixed with the help of the electromagnetic lock. At the same time, the U-shaped recess of the sealing plate will cover the outer wall of the protrusion again, so that the mounting device will not be able to detach from the outer wall of the cable.

[0031] S3: Current alarm. When current flows through the cable, the current will be conducted to the copper wire through the mounting device. When current flows inside the copper wire, the coil will send a signal to the second circuit board to remind the operator to be careful of residual current.

[0032] S4: Disassembly steps. When the entire device needs to be removed, the control workstation must first send a signal to circuit board one. This will unlock the electromagnetic lock. After the electromagnetic lock is unlocked, the spring will push the fixing sleeve away from the cable, thus unlocking the mounting device. Then the mounting device can be removed. After the mounting device leaves the outer wall of the cable, it will send a signal to the workstation. The workstation will then send a signal to circuit board two. After receiving the signal, circuit board two will control the motor to rotate. The rotation of the motor will cause the cam to squeeze the pawl, thus causing the pawl to disengage from the outer wall of the ratchet. At this time, the rotation of the locking wheel will no longer be restricted. Then the moving clamp can be moved outward to move it away from the bracket. After that, the grounding device can be removed from the outside of the bracket.

[0033] The present invention has the following beneficial effects:

[0034] 1. In this invention, by setting up a mounting device and a grounding device with communication functions, when mounting is required, the grounding device must first be fixed to the outside of the grounding bracket so that the grounding device can send a signal to control the mounting component to unlock. When the grounding device needs to be removed, the mounting component must first be removed from the outside of the cable so that the grounding device can be unlocked and then removed. Through the mutual supervision between the mounting device and the grounding device, problems such as hanging the grounding wire while it is energized, failing to remove the grounding rod and energizing, and false grounding can be prevented, thereby increasing work safety.

[0035] 2. In this invention, by setting a coil, the grounding device can detect the copper wire. When there is residual current inside the copper wire, the coil can react and send a signal to the second circuit board. The second circuit board will then send a signal to the workstation, thus alerting the operator to the residual current inside the copper wire and preventing the copper wire from becoming electrified and harming the operator.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0047] Reference Figures 1-3 One embodiment of the present invention provides: an intelligent anti-misoperation interlocking system for high-voltage maintenance grounding rods, comprising:

[0048] The mounting device 1 is mounted on the outside of the cable. The mounting device 1 includes a housing 11, which is U-shaped. During mounting, the housing 11 can be mounted on the outer wall of the cable by means of the U-shaped recess. At the same time, the housing 11 can also protect the internal structure of the mounting device 1. The upper surface of the housing 11 is equipped with a cover plate 15 for sealing the housing 11. The inner wall of the housing 11 is slidably connected to a fixing sleeve 12. A hook 16 is inserted into the inner wall of the fixing sleeve 12. The fixing sleeve 12 can be used to protect the hook 16. An electromagnetic lock 19 is installed on the inner wall of the housing 11 near the rear end. The electromagnetic lock 19 is existing technology. When energized, the locking block protrudes to achieve locking. The rear surface of the fixing sleeve 12 is provided with a locking tongue 18. The upper surface of the electromagnetic lock 19 is equipped with a circuit board 13 for controlling the operation of the internal structure of the mounting device 1. The upper surface of the fixing sleeve 12 is equipped with a sealing plate 14 for sealing the opening above the fixing sleeve 12.

[0049] Reference Figure 1 , Figure 6 and Figure 7The grounding device 2 is used to release current. The grounding device 2 includes a housing 21, which can protect the entire grounding device 2. A cover plate 23 is installed on the upper surface of the housing 21. A fixing frame 24 for conducting current is installed on the upper surface of the cover plate 23. A sliding frame 27 for supporting the movable clamp 25 is fixedly connected to the inner wall of the housing 21. A movable clamp 25 for squeezing the support is slidably connected to the outer wall of the sliding frame 27. The movable clamp 25 can be clamped and fixed by moving back and forth with the fixing frame 24. A circuit board 26 is installed on the inner wall of the housing 21. Communication elements are installed inside both the circuit board 13 and the circuit board 26, which can realize remote signal transmission. A locking component 28 is provided on the inner wall of the fixing frame 24 for locking the movable clamp 25.

[0050] Copper wire 3 is used to transmit current. One end of copper wire 3 is fixedly connected to the outer wall of hook 16. When the surface of hook 16 is energized, the current will be conducted to copper wire 3. The other end of copper wire 3 is fixedly connected to the outer wall of fixing frame 24. When the current is conducted to copper wire 3, copper wire 3 will transmit the current to fixing frame 24. Hook 16 and fixing frame 24 are both made of conductive materials.

[0051] Workstation 4 is used to receive signals. Workstation 4 is connected to circuit board 13 and circuit board 26. Workstation 4 is equipped with a sound-emitting element. When circuit board 13 and circuit board 26 send signals to workstation 4, workstation 4 can prompt the operator through the sound-emitting element.

[0052] Grounding rod 5 is installed on the front surface of hook 16.

[0053] Reference Figures 4-6 The mounting device 1 also includes a spring element 17 for pushing the fixed sleeve 12 to move. The spring element 17 is installed at one end of the electromagnetic lock 19 near the sealing plate 14. When the fixed sleeve 12 moves toward the electromagnetic lock 19, the fixed sleeve 12 will squeeze the spring element 17 to shrink it. The outer walls of the sealing plate 14 and the hook 16 are provided with protrusions 141. When the protrusions 141 are in the U-shaped recess of the housing 11, the electric chain will be restricted and cannot be disengaged from the U-shaped recess of the housing 11. The left and right surfaces of the fixed sleeve 12 are fixedly connected with sliders 121. The inner wall of the housing 11 is provided with a slide rail 111 for supporting the movement of the sliders 121. The grounding device 2 also includes a coil 22 for detecting the current inside the copper wire 3. The coil 22 is installed on the inner wall of the housing 21. The copper wire 3 passes through the center of the coil 22. When the copper wire 3 is charged, a magnetic field will be generated inside the coil 22 due to the principle of electromagnetic induction. Thus, it can be determined whether there is residual current inside the copper wire 3.

[0054] Reference Figures 6-8The locking assembly 28 includes a locking wheel 281 for restricting the movement of the movable clamp 25. The locking wheel 281 is rotatably connected to the inner wall of the housing 11. The movable clamp 25 is provided with a toothed groove 252 at one end near the locking wheel 281. The toothed groove 252 meshes with the locking assembly 28. When the movable clamp 25 moves back and forth, it will squeeze the locking wheel 281 through the toothed groove 252, thus driving the locking wheel 281 to rotate. A ratchet 282 is fixedly connected to the upper surface of the locking wheel 281. When the locking wheel 281 rotates, it will drive the ratchet 282 to rotate synchronously. A pawl 283 for restricting the unidirectional rotation of the ratchet 282 is rotatably connected to the inner wall of the housing 11.

[0055] Reference Figures 6-8 The pawl 283 is elastically connected to the inner wall of the housing 11 by a spring 284. The spring 284 can pull the pawl 283 into the ratchet 282 through its own elastic deformation. A motor 285 is installed on the inner wall of the housing 11. A cam 286 is fixedly connected to the outer wall of the output shaft of the motor 285. By starting the motor 285, the cam 286 can be rotated, which can push the pawl 283 to rotate. This can cause the pawl 283 to overcome the tension of the spring 284 and disengage from the outer wall of the ratchet 282. A pressure block 251 is installed on the rear surface of the moving clamp 25. The pressure block 251 is made of rubber and has elastic deformation capability, which can eliminate the locking gap between the pawl 283 and the locking wheel 281.

[0056] This invention also provides a method for using an intelligent anti-misoperation interlocking system for high-voltage maintenance grounding rods, comprising the following steps;

[0057] S1: Preparation steps: Before mounting the mounting device 1, the grounding device 2 needs to be fixed to the grounding line or the outer wall of the grounding bracket. Specifically, first, attach the fixing bracket 24 to the outer wall of the bracket, then press the movable clamp 25 to move the pressure block 251 closer to the bracket. The pressure block 251 will squeeze the outer wall of the bracket, thus fixing the housing 21 to the outer wall of the bracket with the help of the fixing bracket 24 and the pressure block 251. Then, the movable clamp 25 can be released. When the movable clamp 25 moves, it will drive the locking component 28 to rotate through 252. When the movable clamp is released... After 25, the pawl 283 will be driven by the spring 284 to engage with the inner wall of the ratchet 282. At this time, the locking wheel 281 will be restricted from rotating in the opposite direction. Thus, the moving clamp 25 will be restricted from moving away from the bracket. After the fixing bracket 24 is fixed to the bracket, the grounding device 2 can send a signal to the workstation 4 through the second circuit board 26. In this way, the workstation 4 will send a signal to the first circuit board 13. The first circuit board 13 will control the electromagnetic lock 19 to unlock. Then the elastic element 17 will push the fixing sleeve 12 to drive the protrusion 141 to disengage from the U-shaped recess of the housing 11.

[0058] S2: Installation steps: After the mounting device 1 is unlocked, the mounting device 1 can be mounted on the outer wall of the cable. Then, the housing 11 can be pushed to drive the electromagnetic lock 19 to re-fit onto the outer wall of the lock tongue 18. In this way, the lock tongue 18 can be re-fixed with the help of the electromagnetic lock 19. At the same time, the U-shaped recess of the sealing plate 14 will cover the outer wall of the protrusion 141 again, so that the mounting device 1 will not be able to detach from the outer wall of the cable.

[0059] S3: Current alarm. When current flows through the cable, the current will be conducted to the copper wire 3 through the mounting device 1. When current flows inside the copper wire 3, the coil 22 will send a signal to the circuit board 26 to remind the operator to be careful of residual current.

[0060] S4: Disassembly steps. When the entire device needs to be disassembled, the control workstation 4 needs to send a signal to circuit board 13 first, which will unlock the electromagnetic lock 19. After the electromagnetic lock 19 is unlocked, the spring element 17 will push the fixing sleeve 12 away from the cable, thus unlocking the mounting device 1. Then the mounting device 1 can be removed. After the mounting device 1 leaves the outer wall of the cable, it will send a signal to the workstation 4. The workstation 4 will then send a signal to circuit board 26 second. After receiving the signal, circuit board 26 second will control the motor 285 to rotate. The rotation of the motor 285 will drive the cam 286 to squeeze the pawl 283, thus causing the pawl 283 to disengage from the outer wall of the ratchet 282. At this time, the rotation of the locking wheel 281 will no longer be restricted. Then the moving clamp 25 can be moved outward to move it away from the bracket. After that, the grounding device 2 can be removed from the outside of the bracket.

[0061] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
