Description

Technical Field

[0001] The present invention relates to the field of electrical safety technology, and in particular to a grounding wire device and a use method thereof. Background Art

[0002] When performing on-site maintenance tasks on the distribution network, in order to prevent someone from accidentally supplying power and the static electricity generated by the equipment itself from causing harm to the maintenance personnel, it is necessary to hang a ground wire.

[0003] At present, the conventional way to hang the ground wire is to use a tester to confirm that the line is without electricity before hanging the ground wire. However, most of the existing methods of electricity testing are contact testing, that is, it is necessary to touch the charged object with a tester pen to determine whether it is energized, but if a sudden reverse power supply occurs at this time, it is very likely to cause the risk of electric shock to personnel. In addition, the traditional combined grounding wire and the phase-splitting grounding wire need to be fixed to the ground with a special grounding clamp during operation. The connection status is judged only by the naked eye, which is easy to cause misjudgment and cause serious personal safety accidents and equipment damage. The existing intelligent grounding wire has a certain function of monitoring the connection status of the grounding wire, but it lacks data recording and support for subsequent operation and maintenance management. The on-site work supervisor and work guardian cannot grasp the actual situation of the on-site grounding wire disassembly and installation operations, and cannot grasp the reliability of the grounding wire hanging and grounding in real time.

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0039] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0041] In the description of this embodiment, the terms "upper", "lower", "right", etc., directions or positional relationships are based on the directions or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] like Figures 1 to 7As shown, this embodiment provides a grounding wire device, which includes an integrated device 1, a clamping device 2 and a grounding wire. Among them, the integrated device 1 includes a non-contact inductive probe 11, an alarm mechanism 12, an inductive module, a pressure detection module and a display module 13. The inductive module is electrically connected to the non-contact inductive probe 11 and the alarm mechanism 12 respectively. The inductive module can sense the charged state of the device to be inspected through the non-contact inductive probe 11, and the alarm mechanism 12 can alarm when the inductive module senses that the device to be inspected is charged. The clamping device 2 is used to clamp the wire of the device to be inspected, the pressure detection module is electrically connected to the display module 13, the pressure detection module can detect the clamping force when the clamping device 2 clamps the wire of the device to be inspected, and the display module 13 is used to display and record the clamping force in real time. One end of the grounding wire is conductively connected to the wire of the device to be inspected through the clamping device 2, and the other end of the grounding wire can be grounded.

[0043] By using a non-contact inductive probe 11 and an electric induction module to detect the current in the environment, it is possible to achieve electrical detection without directly contacting the device to be tested that may be energized, and an alarm can be sounded through the alarm mechanism 12 when detecting the current, thereby effectively preventing the operator from accidentally touching the live wire with the grounding wire, thereby enhancing the safety and reliability of on-site operations. The connection status of the grounding wire is also recorded and saved in real time in the form of data through the pressure detection module and the display module 13, which not only ensures that the entire grounding operation process is safe, reliable, efficient and orderly, but also facilitates the subsequent operation and maintenance management of the grounding wire device.

[0044] Optionally, the alarm mechanism 12 in this embodiment adopts an audible and visual alarm. When the electric induction module detects the current, the audible and visual alarm will emit a continuous "beeping" alarm sound, accompanied by a strong red light prompt, to ensure that the operator can be reminded in time, and enhance the safety and reliability of the on-site operation. It is understandable that in some other embodiments, the alarm mechanism 12 can also adopt other forms of alarm devices according to actual needs, such as a buzzer, etc., which is not limited here.

[0045] Furthermore, the integrated device 1 also includes a voice module. When the clamping force detected by the pressure detection module is less than the set value, the voice module can issue a voice warning, thereby realizing a comprehensive and efficient on-site safety protection mechanism. Specifically, the above-mentioned set value refers to the minimum pressure value required to ensure that the clamping device 2 clamps the wire of the equipment to be inspected. When the clamping state of the clamping device 2 becomes loose, the pressure detection module can quickly capture this change and immediately display the detection data on the display module 13. At the same time, the voice module issues a voice to warn the operator. After hearing the warning voice, the operator promptly adjusts the clamping state of the clamping device 2, thereby ensuring the tightness and stability of the grounding wire connection, thereby ensuring that the entire grounding operation process is safe, reliable, efficient and orderly.

[0046] It is also necessary to explain that Figure 7 As shown, in this embodiment, the integrated device 1 is internally integrated with a data acquisition terminal and a data receiving terminal, and the data acquisition terminal includes an electric induction module, a first communication module, an acoustic and optical module, a pressure detection module, a first power module and a firmware module; the data receiving terminal includes a second communication module, a display module 13, a voice module, a GPS module and a second power module. Among them, the first power module supplies power to the remaining modules in the data acquisition terminal, and the functions of the electric induction module, the acoustic and optical module and the pressure detection module in the data acquisition terminal have been described in detail above, and will not be repeated here. The first communication module is connected to the second communication module for communication, and then the data of the data acquisition terminal is transmitted to the data receiving terminal. The firmware module is a prior art and will not be repeated here; the second power module supplies power to the remaining modules in the data receiving terminal, and the functions of the display module 13 and the voice module in the data acquisition terminal have been described in detail above, and will not be repeated here. The GPS module is used to obtain the alarm location. By integrating multiple functional modules into the integrated device 1, the grounding wire device realizes multiple functions while greatly simplifying its structure quantity and improving the intelligence of the grounding wire device.

[0047] Furthermore, if Figure 3 As shown, in this embodiment, a charging port 14 is also provided on the integrated device 1, so as to facilitate charging of the first power module and the second power module in the integrated device 1.

[0048] Furthermore, if Figure 3 As shown, in this embodiment, a plurality of function buttons 15 are further provided on the integrated device 1 , and the plurality of function buttons 15 are connected to a plurality of function modules inside the integrated device 1 , thereby facilitating maintenance personnel to operate the integrated device 1 .

[0049] Optionally, to achieve a stable electrical connection between the wire of the device to be tested and the ground wire, as Figure 3 As shown, the clamping device 2 in this embodiment includes a clamping frame 21 and a clamping block 23. The clamping block 23 is movably disposed in the clamping frame 21. A clamping space is formed between the clamping block 23 and the clamping frame 21. The clamping block 23 is conductively connected to one end of the grounding wire. Optionally, the integrated device 1 is fixed on the clamping frame 21.

[0050] In one embodiment, the clamping frame 21 is U-shaped, and includes two upper and lower parallel cover plates and a side plate connecting the two cover plates on the same side. The integrated device 1 is fixedly set on the upper cover plate, and the clamping block 23 is roughly a square structure. The clamping block 23 can be raised and lowered between the upper cover plate and the lower cover plate. A clamping space is formed between the clamping block 23 and the upper cover plate, and the clamping block 23 is conductively connected to one end of the grounding wire.

[0051] The wire of the device to be inspected is stably clamped by the clamp block 23 and the clamp frame 21, and the clamp block 23 is conductively connected to one end of the grounding wire, so that the wire of the device to be inspected and the grounding wire can be stably electrically connected. At the same time, the integrated device 1 is fixedly set on the clamp frame 21, so that the maintenance personnel no longer need to hold the integrated device 1 separately, which is more convenient for the maintenance personnel to operate, and the clamp block 23 can be raised and lowered in the clamp frame 21, which can clamp wires of different diameters, thereby increasing the application range of the grounding wire device.

[0052] It is understandable that in some other embodiments, the clamping device 2 may also adopt other types of clamping structures according to actual needs, as long as a stable electrical connection between the wire end of the device to be inspected and the ground wire can be achieved, and there is no limitation here.

[0053] Furthermore, in order to achieve stable lifting of the clamping block 23 in the clamping frame 21, as Figure 3 As shown, in this embodiment, the clamping device 2 further includes a first screw 22 and a first bearing 24. A screw hole 211 is provided on the lower cover plate of the clamping frame 21. The first screw 22 is screwed to the screw hole 211. The first bearing 24 is fixedly arranged on the clamping block 23. One end of the first screw 22 extending into the clamping frame 21 is inserted into the first bearing 24. With this arrangement, when the first screw 22 rotates, the clamping block 23 can be driven to freely rise and fall in the clamping frame 21. At the same time, due to the stability of the threaded lifting, the clamping block 23 can be stably lifted and lowered in the clamping frame 21.

[0054] Alternatively, if Figure 3 As shown, in this embodiment, a slide rail 212 is further provided on the side plate of the clamping frame 21, and a slider 231 is provided on the clamping block 23 opposite to the slide rail 212. The slider 231 is provided with a slide groove, and the slider 231 is slidably connected to the slide rail 212 through the slide groove. When the clamping block 23 is raised and lowered in the clamping frame 21, the slider 231 can slide on the slide rail 212, and then can guide the clamping block 23. Through this arrangement, the lifting and lowering of the clamping block 23 in the clamping frame 21 is more stable.

[0055] It is understandable that in some other embodiments, other forms of sliding structures may also be used, such as providing a slide groove on the side panel of the clamping frame 21, and allowing the slider 231 to slide in the slide groove, which can also make the lifting and lowering of the clamping block 23 in the clamping frame 21 more stable, and there is no limitation here.

[0056] Furthermore, in order to facilitate maintenance personnel to rotate the first screw 22, as shown in FIG. Figure 3As shown, a rotating grip member 221 is further provided at one end of the first screw rod 22 outside the clamping frame 21. Thus, the operator can rotate the first screw rod 22 by rotating the rotating grip member 221, which is more convenient for maintenance personnel to operate. Optionally, in this embodiment, the rotating grip member 221 is a rotating rod, which has a simple structure and low cost. Further optionally, there are multiple rotating rods, and the multiple rotating rods are arranged at intervals in the circumferential direction of the first screw rod 22. Of course, in some other embodiments, the rotating grip member 221 can also be of other structures, as long as it is convenient for maintenance personnel to operate, and no limitation is made here.

[0057] Further, as Figure 3 shown, in this embodiment, a handle 7 is further connected to the side plate of the clamping frame 21, and an insulating sleeve 8 is sleeved on the handle 7. Through this setting, the maintenance personnel only need to hold the handle 7 with one hand to lift the integrated device 1 and the clamping device 2, which is more convenient for the maintenance personnel to perform inspections. At the same time, when the maintenance personnel hold the insulating sleeve 8, it can not only prevent electric shock and improve safety, but also make the holding feel more comfortable.

[0058] Further, as Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, in this embodiment, the grounding wire device further includes a wire winding device 3. By using the wire winding device 3 to wind part of the grounding wire, the effective length of the grounding wire can be adjusted and it is convenient for storage. Optionally, the grounding wire includes a first grounding wire 5 and a second grounding wire 6. The wire winding device 3 includes a support frame 31, a first housing 32, a second housing 33, a conductive ring 38 and a rotatable conductive shaft 34. The conductive ring 38 is sleeved outside the conductive shaft 34 and is in conductive contact with the conductive shaft 34. One end of the first grounding wire 5 is conductively connected to the clamping device 2, and the other end is conductively connected to the conductive ring 38. The second grounding wire 6 is wound around the conductive shaft 34. One end of the second grounding wire 6 is conductively connected to the conductive shaft 34, and the other end of the second grounding wire 6 can be grounded. The first housing 32 covers the conductive shaft 34, the second housing 33 covers the conductive ring 38, and the support frame 31 is used to support the first housing 32 and the second housing 33.

[0059] In one embodiment, the support frame 31 is generally in a "U" - shaped structure, which includes two vertical side walls and a bottom plate. Both the first housing 32 and the second housing 33 are cylindrical housings. The first housing 32 is arranged inside the two vertical side walls of the support frame 31, and the two circular side walls of the first housing 32 are respectively opposite to the inner wall surfaces of the two vertical side walls. The second housing 33 is arranged outside one of the vertical walls of the support frame 31, and one circular side wall of the second housing 33 is opposite to the outer wall surface of this vertical side wall.

[0060] The two ends of the conductive shaft 34 pass through the two circular side walls of the first shell 32 respectively, and one end of the conductive shaft 34 continues to pass through the vertical side wall of the support frame 31 and the circular side wall of the second shell 33 toward the second shell 33, that is, the conductive shaft 34 is disposed in the first shell 32 and the second shell 33.

[0061] One end of the first grounding wire 5 is electrically connected to the clamping block 23, and the other end of the first grounding wire 5 is electrically connected to the conductive ring 38, wherein a second wire hole 331 is provided on the second shell 33, and the first grounding wire 5 can pass through the second wire hole 331 to be electrically connected to the conductive ring 38. The second grounding wire 6 is arranged in the first shell 32, and the second grounding wire 6 is coiled on the conductive shaft 34, one end of the second grounding wire 6 is electrically connected to the conductive shaft 34, and the other end of the second grounding wire 6 can be grounded, wherein a first wire hole 321 is provided on the first shell 32, and the second grounding wire 6 can pass through the first wire hole 321 to be grounded.

[0062] Through the above arrangement, the grounding wire is divided into a first grounding wire 5 and a second grounding wire 6, and the second grounding wire 6 is coiled in the first housing 32, thereby preventing a large number of grounding wires from being scattered on the ground during maintenance, thereby reducing the possibility of maintenance personnel accidentally touching the grounding wires, and further improving the safety of on-site operations. At the same time, the second grounding wire 6 is coiled in the first housing 32, which can effectively protect the grounding wire while extending the service life of the grounding wire device and reducing maintenance costs.

[0063] To facilitate the rotation of the conductive shaft 34, Figure 5 As shown, the conductive shaft 34 passes through the through holes of the two circular side walls of the first shell 32 , and the second bearings 35 are arranged. The conductive shaft 34 is inserted into the second bearings 35 , so that the conductive shaft 34 can rotate more smoothly.

[0064] To realize automatic recovery of the second grounding wire 6, the second grounding wire 6 is wound on the conductive shaft 34. Figure 5 As shown, the winding device 3 also includes a coil spring 36, which is sleeved outside the conductive shaft 34, and one end of the coil spring 36 is connected to the conductive shaft 34, and the other end of the coil spring 36 is connected to the first housing 32. When the second grounding wire 6 is pulled outward by an external force, it will drive the conductive shaft 34 to rotate. At this time, the coil spring 36 can accumulate elastic force. When the external force on the second grounding wire 6 disappears, the coil spring 36 can drive the conductive shaft 34 to reset and rotate through its own accumulated elastic force, and while the second grounding wire 6 is recovered to the first housing 32, the second grounding wire 6 is directly wound on the conductive shaft 34. Through this arrangement, it is greatly convenient for maintenance personnel to recover the grounding wire after the inspection is completed, and the labor intensity of maintenance personnel is reduced.

[0065] Alternatively, if Figure 3As shown, in this embodiment, two disc springs 36 are provided, and are respectively provided on both sides of the second grounding wire 6. Such a configuration can make the conductive shaft 34 more stable when it is reset and rotated, and prevent the shaft from being stuck when the second grounding wire 6 is recovered. Of course, in some other implementations, the number of disc springs 36 can also be set according to actual needs, and is not limited here.

[0066] Furthermore, if Figure 5 As shown, the winding device 3 also includes an insulating limiting structure 37, which is arranged between the coil spring 36 and the second grounding wire 6. While limiting the second grounding wire 6, the coil spring 36 is prevented from being in conductive contact with the second grounding wire 6, thereby further improving the safety of the grounding wire device. Optionally, in this embodiment, the insulating limiting structure 37 is an insulating ring.

[0067] Furthermore, if Figure 4 As shown, a third wire hole 311 is also provided on the bottom plate of the support frame 31, and the second grounding wire 6 passes through the first wire hole 321 and then passes through the third wire hole 311. The second grounding wire 6 is straightened in advance through the third wire hole 311, which makes it easier to ground or recycle the second grounding wire 6.

[0068] To facilitate grounding the ground wire, Figure 1 , Figure 2 and Figure 6 As shown, the grounding wire device also includes a grounding device 4, which includes a third shell 41, a driving mechanism 42, a connecting structure and a cone head 46. Optionally, the third shell 41 is roughly a long cylindrical structure with three sections of different diameters, and the driving mechanism 42, the connecting structure and the cone head 46 are sequentially arranged in the third shell 41 from top to bottom, and the cone tip of the cone head 46 protrudes from the outside of the third shell 41. The driving mechanism 42 is connected to the cone head 46 through the connecting structure, and the driving mechanism 42 can drive the cone head 46 to move, and the other end of the grounding wire is connected to the cone head 46. The cone head 46 is driven by the driving mechanism 42 to drill into the ground, and at the same time, the cone head 46 drives the grounding wire to drill under the ground, thereby achieving grounding of the grounding wire.

[0069] Specifically, in this embodiment, the second grounding wire 6 extending from the wire winding device 3 is connected to the cone head 46 .

[0070] Alternatively, if Figure 6As shown, in this embodiment, the output end of the driving mechanism 42 can output rotational motion, and the connection structure includes a nut 43, a connecting rod 44, and a second screw 45. One end of the connecting rod 44 is fixedly connected to the output end of the driving mechanism 42, and the other end of the connecting rod 44 is fixedly connected to the nut 43. The second screw 45 is screwed to the nut 43, and one end of the second screw 45 away from the driving mechanism 42 is fixedly connected to the cone head 46. It should be noted that the length of the thread on the second screw 45 is less than the length of the connecting rod 44, so as to avoid the second screw 45 and the output end of the driving mechanism 42 from touching and causing damage to both.

[0071] The grounding device 4 is placed vertically with the cone head 46 facing the ground. When the output end of the driving mechanism 42 rotates, the nut 43 can be driven to rotate synchronously. At this time, the second screw 45 moves up and down relative to the nut 43, and the cone head 46 on the second screw 45 moves up and down with the second screw 45, thereby realizing the recovery or grounding of the cone head 46. This setting further improves the automation of the grounding wire device and reduces the labor intensity of maintenance personnel.

[0072] Optionally, the driving mechanism 42 in this embodiment is a driving motor. It is understandable that in some other embodiments, the output end of the driving mechanism 42 can also output linear motion, for example, the output end of the driving mechanism 42 can be retracted, and the connection structure between the driving mechanism 42 and the cone head 46 can be adaptively adjusted according to the output type of the driving mechanism 42, as long as the grounding and recovery of the cone head 46 can be achieved, and no limitation is made here.

[0073] Furthermore, since the cone head 46 will cause the entire grounding device 4 to vibrate during the grounding process, in order to prevent the second screw rod 45 from tilting during the movement process, resulting in the occurrence of a jam between the screw rod 45 and the nut 43, as shown in FIG. Figure 6 As shown, in this embodiment, the grounding device 4 further includes a plurality of guide rods 47, which are spaced apart in the circumferential direction of the second screw rod 45, and the two ends of the guide rods 47 are bent toward the third housing 41 and fixed on the third housing 41. A plurality of sliding sleeves 48 are spaced apart in the circumferential direction of the second screw rod 45, and the plurality of sliding sleeves 48 are slidably sleeved with the plurality of guide rods 47 in a one-to-one correspondence. Through this arrangement, the second screw rod 45 is guided and limited by the sliding sleeves 48 during the movement, thereby making the movement of the second screw rod 45 more stable and preventing the screw from getting stuck with the nut 43. In one embodiment, there are two guide rods 47 and two sliding sleeves 48.

[0074] Furthermore, since the cone head 46 generates a reverse force during the grounding process, causing the entire grounding device 4 to move upward, in order to solve this problem, Figure 1 and Figure 2As shown, in this embodiment, a pedal 411 is further provided on the third housing 41. During the grounding process of the cone head 46, the maintenance personnel can step on the pedal 411 to prevent the grounding device 4 from moving upward, so that the cone head 46 can be stably drilled into the ground.

[0075] The grounding wire device provided by the present invention integrates a non-contact inductive probe 11, an alarm mechanism 12, an inductive module, a pressure detection module and a display module 13 into an integrated device 1, so that it has multiple functions, simplifies the overall structure of the grounding wire device, and improves the intelligence of the grounding wire device. The grounding wire device detects the current in the environment through the non-contact inductive probe 11 and the inductive module, realizes the electric detection without directly contacting the charged body, and can alarm through the alarm mechanism 12 when detecting the current, thereby enhancing the safety and reliability of on-site operations. The hooking state of the grounding wire is also recorded and saved in real time in the form of data through the pressure detection module and the display module 13, and a warning is issued through the voice module when there is a problem with the hooking state of the grounding wire, which can not only ensure that the entire grounding operation process is safe, reliable, efficient and orderly, but also the saved data is convenient for the subsequent operation and maintenance management of the grounding wire device. In addition, by setting the winding device 3 and the grounding device 4, not only the safety of on-site operations is further improved, but also the labor intensity of maintenance personnel on site is greatly reduced, so that maintenance personnel can perform maintenance work more safely and conveniently.

[0076] The present invention also provides a method for using a grounding wire device, comprising the following steps:

[0077] S1: Move the grounding wire device to the vicinity of the device to be inspected, and the non-contact inductive probe 11 performs an inductive test on the device to be inspected. If the alarm mechanism 12 does not sound an alarm, proceed to S2; if the alarm mechanism 12 sounds an alarm, the device to be inspected is powered off, and S1 is repeated until the alarm mechanism 12 no longer sounds an alarm.

[0078] S2: The clamping device 2 clamps the wire of the device to be inspected, and one end of the grounding wire is conductively connected to the wire through the clamping device 2, and the other end of the grounding wire can be grounded;

[0079] S3: Using the pressure detection module to detect the clamping force of the clamping device 2 on the wire, using the display module 13 to monitor the clamping force in real time, if the clamping force displayed on the display module 13 is less than the set value, adjusting the clamping device 2 to clamp the wire.

[0080] It should be noted that, in step S1, before the grounding wire device is grounded, the electric induction module is first turned on to perform an induction test. If the alarm mechanism 12 does not sound an alarm, S2 is performed; if the alarm mechanism 12 sounds an alarm, the maintenance personnel checks whether the equipment to be tested is powered off. After confirming that the power is off, S1 is repeated again until the alarm mechanism 12 no longer sounds an alarm.

[0081] In step S2, after the grounding wire device is grounded, the pressure detection module is turned on, and the maintenance personnel conducts real-time monitoring at the display module 13. When the clamping force displayed on the display module 13 changes, the maintenance personnel promptly checks whether the clamping device 2 clamps the wire. If the wire is loose, the wire is clamped again, and it is confirmed whether the displayed clamping force returns to normal. After returning to normal, the maintenance personnel continue to monitor until the maintenance is completed.

[0082] By adopting the above-mentioned method of use, the grounding wire can be effectively prevented from accidentally touching the live wire, significantly enhancing the safety and reliability of on-site operations, allowing maintenance personnel to conduct real-time monitoring safely and efficiently, thereby significantly reducing operational risks, effectively ensuring the safety of maintenance personnel, and improving work efficiency.

[0083] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
