Detailed Implementation

[0025] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] like Figures 1-7 As shown, the grounding wire monitoring device of this embodiment includes a grounding component 1, a monitoring component 2, and a data acquisition component 3. The grounding component 1 includes a grounding wire 11, a grounding clamp 12, and a grounding plug 13. Both ends of the grounding wire 11 are electrically connected to the grounding clamp 12 and the grounding plug 13, respectively. The grounding plug 13 is used to connect to the ground, and the grounding clamp 12 is used to connect to electrical equipment. The monitoring component 2 includes a first detection element 21 and a second detection element 22. The first detection element 21 is disposed on the grounding clamp 12 and is used to detect the connection status between the grounding clamp 12 and the electrical equipment. The second detection element 22 is disposed on the grounding plug 13 and is used to detect the connection status between the grounding wire 11 and the grounding plug 13. The data acquisition component 3 is connected to the monitoring component 2 and is used to acquire the detection signals of the monitoring component 2 and transmit them externally.

[0027] The grounding wire monitoring device of this invention upgrades the traditional manual inspection method of visual inspection and torque wrench tightening to automatic sensor detection through the coordinated work of the grounding clamp, grounding plug, first detection element, second detection element, and acquisition component. This solves the problems of low efficiency and easy omissions in manual inspection. The first and second detection elements monitor the connection status between the grounding clamp and the cable and the connection status between the grounding wire and the grounding plug in real time, which can detect loose or disconnected connections in time, avoiding the risk of injury from induced voltage and malfunction of protection caused by increased grounding circuit impedance. The acquisition component transmits the detection signal outward, realizing remote data feedback of the grounding status.

[0028] Specifically, in grounding assembly 1, the two ends of grounding wire 11 are electrically connected to grounding clamp 12 and grounding plug 13 respectively. Grounding plug 13 is inserted into the ground, and grounding clamp 12 is clamped on the cable of the power equipment, forming a temporary grounding loop from the power equipment to the ground. In monitoring assembly 2, the first detection element 21 detects the connection status between grounding clamp 12 and cable in real time, and the second detection element 22 detects the connection status between grounding wire 11 and grounding plug 13 in real time. Acquisition assembly 3 acquires the detection signals of the first detection element 21 and the second detection element 22 and sends them outward, thereby realizing real-time monitoring and remote transmission of the grounding connection status.

[0029] In some embodiments, the grounding clamp 12 includes a fixed clamp body 121, a movable pressure plate 122, and an adjusting screw 123. The movable pressure plate 122 is slidably connected within the fixed clamp body 121 to clamp the cable of the power equipment between the movable pressure plate 122 and the fixed clamp body 121. The adjusting screw 123 passes through one end of the fixed clamp body 121 and is threadedly connected to the fixed clamp body 121. One end of the adjusting screw 123 located within the fixed clamp body 121 is fixedly connected to the movable pressure plate 122. The adjusting screw 123 is used to adjust the distance between the movable pressure plate 122 and the fixed clamp body 121 to accommodate cables of different sizes.

[0030] The grounding wire monitoring device of this invention, through the cooperation of a fixed clamp, a movable pressure plate, and an adjusting screw, achieves adaptive clamping of cables of different sizes, solving the problem of insecure clamping and poor contact caused by different cable specifications in traditional grounding clamps; through the threaded cooperation between the adjusting screw and the fixed clamp, the movement of the movable pressure plate is controllable and self-locking, ensuring stable and lasting clamping force, avoiding loosening of the clamp due to vibration or external force, and improving the reliability of the grounding connection.

[0031] Specifically, in the grounding clamp 12, the adjusting screw 123 passes through one end of the fixed clamp 121 and is threadedly connected to the fixed clamp 121. The end of the adjusting screw 123 located inside the fixed clamp 121 is fixedly connected to the movable pressure plate 122. The movable pressure plate 122 is slidably connected inside the fixed clamp 121. When the adjusting screw 123 is rotated, the adjusting screw 123 moves axially relative to the fixed clamp 121, causing the movable pressure plate 122 to slide inside the fixed clamp 121, thereby adjusting the distance between the movable pressure plate 122 and the fixed clamp 121, and clamping cables of different sizes between the movable pressure plate 122 and the fixed clamp 121.

[0032] In some embodiments, a cable inlet 124 is provided on one side of the fixed clamp 121, the cable inlet 124 being used to allow the cable to enter between the movable pressure plate 122 and the fixed clamp 121.

[0033] The grounding wire monitoring device of this invention, through the setting of the inlet, allows the cable to directly enter the clamping area from the side of the fixed clamp, without having to pass it through from the end, which simplifies the cable installation operation and improves the convenience of on-site operation, and is especially suitable for operation scenarios with limited space or limited cable length.

[0034] Specifically, a cable inlet 124 is provided on one side of the fixed clamp 121. The cable enters between the movable pressure plate 122 and the fixed clamp 121 through the cable inlet 124, so that the cable can enter the clamping area from the side of the fixed clamp 121.

[0035] In some embodiments, the grounding clamp 12 further includes a first terminal 125, and a terminal 14 is provided at the end of the grounding wire 11. The terminal 14 is sleeved on the first terminal 125 and fixed by a first locking nut 15. A second terminal 16 is provided on the grounding plug 13, and the terminal 14 provided at the end of the grounding wire 11 is sleeved on the second terminal 16 and fixed by a second locking nut 17.

[0036] The grounding wire monitoring device of this invention achieves a detachable and fixed connection between the grounding wire, the grounding clamp, and the grounding plug through the cooperation of the first terminal, the second terminal, the terminal block, and the locking nut, which facilitates quick installation and disassembly on site. The threaded engagement between the locking nut and the terminal ensures a tight fit between the terminal block and the terminal, avoiding increased contact resistance due to loose connection and ensuring the electrical continuity of the grounding circuit.

[0037] Specifically, the grounding clamp 12 is provided with a first terminal 125, the grounding plug 13 is provided with a second terminal 16, the terminal 14 at the end of the grounding wire 11 is sleeved on the first terminal 125 and fixed by the first locking nut 15, and the terminal 14 at the end of the grounding wire 11 is sleeved on the second terminal 16 and fixed by the second locking nut 17, so as to realize the electrical connection between the grounding wire 11, the grounding clamp 12 and the grounding plug 13.

[0038] In some embodiments, the first detection element 21 includes an electronic displacement gauge 211 and a first proximity sensor 212. The electronic displacement gauge 211 is disposed on the grounding clamp 12, with its detection end facing the movable pressure plate 122 to clamp the cable between the movable pressure plate 122 and the electronic displacement gauge 211. The electronic displacement gauge 211 is used to monitor the displacement of the cable. The first proximity sensor 212 is disposed on the grounding clamp 12, with its detection end facing the terminal block 14. The first proximity sensor 212 is used to detect the presence of the terminal block 14.

[0039] The grounding wire monitoring device of this invention, through the cooperation of an electronic displacement meter and a first proximity sensor, achieves dual real-time monitoring of the cable clamping state and the terminal connection state. The electronic displacement meter converts the mechanical displacement of the cable into an electrical signal, which can immediately sense and output the change when the cable is loose, avoiding poor contact caused by loose clamping. The first proximity sensor detects the presence of the terminal and can output a signal in time when the terminal falls off, avoiding the interruption of the grounding circuit caused by the terminal falling off, and eliminating hidden faults that cannot be detected in traditional grounding methods.

[0040] Specifically, the first detection component 21 includes an electronic displacement gauge 211 and a first proximity sensor 212. The electronic displacement gauge 211 is mounted on the grounding clamp 12, with its detection end facing the movable pressure plate 122. The cable is clamped between the movable pressure plate 122 and the electronic displacement gauge 211. The first proximity sensor 212 is mounted on the grounding clamp 12, with its detection end facing the terminal block 14. The electronic displacement gauge 211 monitors the displacement of the cable, and the first proximity sensor 212 detects the presence of the terminal block 14.

[0041] Furthermore, the electronic displacement gauge 211 and the first proximity sensor 212 are existing technologies and will not be described in detail here.

[0042] In some embodiments, the second detection element 22 includes a second proximity sensor 221, the detection end of which faces the terminal 14 connected to the grounding plug 13, and the second proximity sensor 221 is used to detect the presence of the terminal 14.

[0043] The grounding wire monitoring device of this invention, through the setting of a second proximity sensor, performs non-contact real-time monitoring of the wiring terminals at the connection between the grounding wire and the grounding plug. It can immediately output a signal when the wiring terminals fall off due to vibration, external force or loose nut, avoiding the grounding circuit being broken due to the loosening of the grounding wire end, ensuring the connection reliability of the grounding plug side, and realizing all-round monitoring of the connection status of both ends of the grounding device.

[0044] Specifically, the second detection element 22 includes a second proximity sensor 221. The detection end of the second proximity sensor 221 faces the terminal 14 connected to the grounding plug 13. The second proximity sensor 221 detects whether the terminal 14 exists in order to determine the connection status between the grounding wire 11 and the grounding plug 13.

[0045] Furthermore, the second proximity sensor 221 is existing technology and will not be described in detail here.

[0046] In some embodiments, the acquisition component 3 includes a first wireless acquisition unit 31 and a second wireless acquisition unit 32. The first wireless acquisition unit 31 is disposed on the grounding clamp 12 and is connected to the first detection element 21. The second wireless acquisition unit 32 is disposed on the grounding plug 13 and is connected to the second detection element 22.

[0047] The grounding wire monitoring device of this invention, through the setting of a first wireless collector and a second wireless collector, realizes distributed acquisition and wireless transmission of sensor signals from the grounding clamp side and the grounding plug side, avoiding the inconvenience of wired wiring in temporary grounding scenarios; by connecting the wireless collector to the sensor nearby, the signal transmission distance is shortened, improving the reliability and anti-interference capability of signal acquisition; the wireless collector sends the detection signal outward, providing a foundation for subsequent data aggregation and remote monitoring, enabling the grounding device to interface with an intelligent operation and maintenance system.

[0048] Specifically, the acquisition component 3 includes a first wireless acquisition unit 31 and a second wireless acquisition unit 32. The first wireless acquisition unit 31 is mounted on the grounding clamp 12 and connected to the first detection element 21. The second wireless acquisition unit 32 is mounted on the grounding plug 13 and connected to the second detection element 22. The first wireless acquisition unit 31 acquires the detection signal of the first detection element 21, and the second wireless acquisition unit 32 acquires the detection signal of the second detection element 22, and transmits them outwards respectively.

[0049] In some embodiments, the acquisition component 3 further includes a mounting base 33, which is snapped onto the grounding clamp 12 and is used to mount the first detection element 21 and the first wireless acquisition device 31.

[0050] The grounding wire monitoring device of this invention provides a unified installation base for the first detection component and the first wireless data collector through the setting of the mounting base, which simplifies the assembly process of the sensor and the data collector on the grounding clamp; the connection method of the mounting base snapping into the grounding clamp enables the rapid assembly and disassembly of the detection and data acquisition modules, which is convenient for deployment or disassembly on site according to the operation requirements, and improves the flexibility of use and the convenience of maintenance of the device.

[0051] Specifically, the acquisition component 3 also includes a mounting base 33, which is snapped onto the grounding clamp 12. The first detection element 21 and the first wireless acquisition device 31 are mounted on the mounting base 33, and the first detection element 21 and the first wireless acquisition device 31 are fixed to the grounding clamp 12 by the mounting base 33.

[0052] In some embodiments, the mounting base 33 includes a fixed base body 331, a clamping plate 332, and an adjusting bolt 333. The clamping plate 332 is slidably installed in the fixed base body 331. One end of the adjusting bolt 333 passes through the fixed base body 331 and abuts against the fixed clamp 121. The adjusting bolt 333 is threadedly connected to the fixed base body 331.

[0053] The grounding wire monitoring device of this invention achieves an adjustable clamping connection between the mounting base and the fixed clamp through the cooperation of the fixed base, the clamping plate and the adjusting bolt; by adjusting the thread of the adjusting bolt, the clamping force is controllable and adjustable, which can adapt to fixed clamps of different sizes or shapes, avoiding the mounting base shaking due to excessively loose clamping or the clamp being damaged due to excessively tight clamping, thus improving the adaptability and fixing reliability of the mounting base.

[0054] Specifically, the mounting base 33 includes a fixed base body 331, a clamping plate 332, and an adjusting bolt 333. The clamping plate 332 is slidably installed inside the fixed base body 331. One end of the adjusting bolt 333 passes through the fixed base body 331 and abuts against the fixed clamp 121. The adjusting bolt 333 is threadedly connected to the fixed base body 331. When the adjusting bolt 333 is rotated, the adjusting bolt 333 moves axially relative to the fixed base body 331, pushing the clamping plate 332 to move towards the fixed clamp 121, so that the mounting base 33 is clamped on the fixed clamp 121.

[0055] In some embodiments, the grounding wire monitoring device further includes a fixing clamp 4, which is sleeved on the insulating operating rod 5. The insulating operating rod 5 is fixedly connected to the adjusting screw 123 of the grounding clamp 12. A wireless receiver 6 is installed on the fixing clamp 4, and the wireless receiver 6 is connected to the first wireless collector 31 and the second wireless collector 32.

[0056] The grounding wire monitoring device of this invention provides a convenient installation position for the wireless receiver through the setting of fixing clamps and insulating operating rods, allowing the wireless receiver to move together with the insulating operating rods for easy on-site deployment; through the wireless connection between the wireless receiver and the first and second wireless collectors, the detection signals are collected and converged without the need for additional wiring, meeting the rapid deployment requirements of temporary grounding operations; the centralized reception of signals by the wireless receiver provides a data interface for subsequent data uploading to a remote platform.

[0057] Specifically, the fixing clamp 4 is sleeved on the insulating operating rod 5, and the insulating operating rod 5 is fixedly connected to the adjusting screw 123 of the grounding clamp 12. The wireless receiver 6 is installed on the fixing clamp 4 and is connected to the first wireless collector 31 and the second wireless collector 32. The wireless receiver 6 receives the detection signals sent by the first wireless collector 31 and the second wireless collector 32.

[0058] Furthermore, the wireless receiver 6 is existing technology and will not be described in detail.
