[0049] The application will be further described below in conjunction with the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the application, and not to limit the application. In addition, it should be noted that, for the convenience of description, only the parts related to the application are shown in the drawings, not all the structures.

[0050] In the description of the application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the application can be understood according to the specific circumstances.

[0051] In the present application, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature "on", "above" and "over" the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the first feature is higher in horizontal height than the second feature. The first feature "under", "below" and "under" the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the first feature is lower in horizontal height than the second feature.

[0052] In the description of the present embodiment, the terms "upper", "lower", "right", "left", and other orientation or position relationships are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0053] With the rapid development of science and technology, electrical equipment is increasingly used, and people's demand for electricity is increasingly widespread. The maintenance and normal maintenance of lines and equipment also increase accordingly. In order to ensure the safety of personnel, the line to be maintained or maintained needs to be grounded at one end. However, in the actual operation process, the length of the original grounding wire 30 is usually limited, and the range it can reach is limited, especially in urban areas, the line is mostly hard ground 20 such as cement ground, and the grounding wire is limited by the environment, so the wire cannot be normally connected to the ground.

[0054] In order to solve the above problems, as shown in Figure 1 The grounding device provided by the present embodiment includes a support 1, a grounding needle 2 and a winding disc 3. The support 1 is movably arranged, the grounding needle 2 is configured to be capable of being inserted into the muddy ground 10, the winding disc 3 is rotatably arranged on the support 1, the extension grounding wire 31 is wound on the winding disc 3, the first end of the extension grounding wire 31 is capable of being electrically connected with the original grounding wire 30, and the second end of the extension grounding wire 31 is capable of being electrically connected with the grounding needle 2.

[0055] In use, the first end of the extension grounding wire 31 is electrically connected with the original grounding wire 30, the second end of the extension grounding wire 31 is electrically connected with the grounding needle 2, then the support 1 and the grounding needle 2 are dragged to move, so that the winding disc 3 continuously unwinds the first end of the extension grounding wire 31, until the grounding needle 2 is inserted into the suitable muddy ground 10 after moving, so that the grounding of the wire can be realized. As can be seen, the grounding device provided by the present embodiment can accommodate a sufficient length of the extension grounding wire 31 by arranging the winding disc 3, so that the extension grounding wire 31 can be extended to the muddy ground 10 suitable for the grounding needle 2 to be inserted, and is not limited by the environment.

[0056] In an optional embodiment, as shown in Figure 1 The grounding device further comprises a motor 32, which is powered by a power supply 50. The main body of the motor 32 is fixed to the support 1, and the output shaft of the motor 32 is connected to the winding reel 3. In this way, the winding reel 3 can be driven to rotate by the motor 32, so as to realize automatic winding and unwinding of the grounding wire 31, improve the degree of automation, and save time and effort.

[0057] In actual use, the soil composition of some clay ground 10 may not meet the standard or the soil is too dry, so that the grounding pin 2 cannot be fully in contact with the ground after grounding, and the grounding resistance is often higher than the standard requirement. Since maintenance or maintenance is a matter of seconds to complete the work, the site generally does not make grounding resistance test. Once the grounding resistance is too large, it will bring safety hazards to the on-site workers.

[0058] Therefore, as shown in Figure 2 In this embodiment, a resistance reducing agent 22 is arranged in the grounding pin 2. The resistance reducing agent 22 can effectively reduce the grounding resistance. When the grounding pin 2 is inserted into the clay ground 10, the resistance reducing agent 22 is released into the soil, so that the grounding pin 2 is fully in contact with the ground, thereby reducing the grounding resistance to meet the grounding resistance requirement and reducing the safety hazard problem.

[0059] Further, as shown in Figure 1 The support 1 comprises a first mounting frame 11 and a second mounting frame 12. The first mounting frame 11 is U-shaped with the opening upward, and the winding reel 3 is horizontally and rotatably arranged on the first mounting frame 11. The second mounting frame 12 is also U-shaped and has an installation cavity 121 inside. The opening end of the second mounting frame 12 is connected to the bottom of the first mounting frame 11, and the grounding pin 2 is arranged at the bottom of the second mounting frame 12.

[0060] In this embodiment, the grounding device further comprises a hammering assembly 4 arranged in the installation cavity 121. The hammering assembly 4 comprises a vibration hammer 41, a vibration coil 42, and a return spring 43. The vibration hammer 41 is arranged at the bottom of the installation cavity 121. The vibration coil 42 is annularly arranged on the side of the vibration hammer 41 and is electrically connected to the power supply 50. One end of the return spring 43 is in abutment with the vibration hammer 41, and the other end is in abutment with the first mounting frame 11. After the power supply 50 supplies power to the vibration coil 42, the vibration hammer 41 repeatedly performs up-and-down hammering action under the magnetic force of the vibration coil 42 and the elastic force of the return spring 43, thereby generating downward pressing power to the grounding pin 2 at the bottom of the second support 1, and automatically driving the grounding pin 2 into the clay ground 10, saving time and effort.

[0061] Further, as shown in Figure 1 and Figure 2As shown, the grounding device further comprises a metal detection assembly 5, which comprises a metal sensor 51 arranged in the tip of the grounding pin 2 and an induction switch 52 connected between the vibration coil 42 and the power supply 50 and capable of controlling the circuit between the vibration coil 42 and the power supply 50, and the induction switch 52 is in communication connection with the metal sensor 51, specifically wireless connection.

[0062] The metal sensor 51 can sense the presence of underground metal. After inserting the grounding pin 2 at a suitable position, place the support 1 on the top of the grounding pin 2, and turn on the switch of the power supply 50. If the metal sensor 51 senses the presence of metal underground, the induction switch 52 is triggered to open, the circuit between the power supply 50 and the vibration coil 42 is disconnected, and the insertion of the grounding pin 2 into the ground is stopped. At this time, the grounding position needs to be changed. If the metal sensor 51 senses that there is no metal underground, the induction switch 52 remains closed, the circuit between the power supply 50 and the vibration coil 42 remains connected, and the vibration hammer 41 continues to drive the grounding pin 2 into the ground. In this way, it can effectively avoid the grounding pin 2 from hitting hard objects (water supply pipes) underground or piercing possible power circuits or communication circuits, causing secondary accidents and injuries.

[0063] As shown in Figure 1 , Figure 3 and Figure 4 , the bottom of the second mounting bracket 12 is provided with a limiting cavity 122 and a slot 123 communicating with the limiting cavity 122, and the top of the grounding pin 2 is provided with a limiting pin 21 which can be inserted into the limiting cavity 122 from the slot 123 and be limited in the limiting cavity 122 by rotating. The limiting cavity 122 can be a cylindrical cavity, the slot 123 is a long strip, the limiting pin 21 is matched with the shape of the slot 123, and the depth of the limiting cavity 122 is greater than the height of the limiting pin 21. During assembly, first insert the grounding pin 2 at a suitable position, then place the support 1 on the top of the grounding pin 2, first ensure that the limiting pin 21 is opposite to the slot 123, so that the limiting pin 21 can be inserted into the limiting cavity 122 from the slot 123, which is convenient for disassembly.

[0064] Further, as shown in Figure 1 , the bottom of the support 1 is provided with a pin pulling head 6, which can be an electric cylinder. The cylinder body 61 of the pin pulling head 6 is fixed to the bottom of the support 1, and the output rod 62 of the pin pulling head 6 can extend out of the cylinder body 61 and abut against the soil surface 10. After completing the grounding work, the output rod 62 of the pin pulling head 6 gradually extends out of the cylinder body 61 until it abuts against the soil surface 10, and then the output rod 62 of the pin pulling head 6 continues to extend. At this time, due to the reaction force of the ground, the pin pulling head 6 lifts the support 1, the support 1 drives the grounding pin 2 to pull out of the ground, easily completing the disassembly work of the grounding pin 2, avoiding the situation that the grounding pin 2 cannot be pulled out or is bent due to the non-perpendicular human force, saving time and effort.

[0065] Further, as Figure 1 shown, the grounding device further comprises a wire arranging assembly 7, the wire arranging assembly 7 comprising a transmission shaft 71 and a wire arranging device 73, the transmission shaft 71 being rotatably arranged on the first mounting frame 11 of the support 1, the reel 3 being in transmission connection with the transmission shaft 71 through a gear set 72, a helical guide groove 711 being formed on the outer side wall of the transmission shaft 71, the wire arranging device 73 being sleeved on the transmission shaft 71, the inner side wall of the wire arranging device 73 being protruded with a protruding tooth, the protruding tooth being in cooperation with the guide groove 711, the first end of the extension grounding wire 31 being arranged through the wire arranging device 73. After the grounding pin 2 is pulled out after the grounding maintenance work is completed, the reel 3 is reeled up by rotating, at the same time, the reel 3 drives the transmission shaft 71 to rotate through the gear set 72, when the transmission shaft 71 rotates, the wire arranging device 73 moves left and right through the cooperation of the guide groove 711 and the protruding tooth in the wire arranging device 73, thereby driving the extension grounding wire 31 to be reeled up on the reel 3 layer by layer in order, and the extension grounding wire 31 is arranged in order during the reeling process.

[0066] Specifically, as Figure 5 shown, the gear set 72 comprises a first gear 721, a second gear 722, a third gear 723 and a fourth gear 724, the first gear 721 being sleeved on the rotating shaft of the reel 3 and being connected through a key, the first gear 721 being in transmission with the second gear 722, the second gear 722 being in transmission with the third gear 723, the third gear 723 being in transmission with the fourth gear 724, the fourth gear 724 being sleeved on the transmission shaft 71 and being connected through a key. Thus, the rotation of the transmission shaft 71 is realized through the meshing transmission of the plurality of gears. The gear transmission mode is stable in transmission, accurate in transmission ratio, reliable in work, compact in structure and high in efficiency.

[0067] The grounding device is used outdoors, thus the connection point 60 of the extension grounding wire 31 and the original grounding wire 30 or the grounding pin 2 is easy to be collided by people or animals, and then the grounding is not firm, which brings safety hazards to the on-site workers.

[0068] Therefore, as Figure 1As shown, in the embodiment, the grounding device further comprises a position detection assembly 8, which comprises a first position detection piece 81, a second position detection piece 82, an alarm transmitting module 83 and a mobile alarm 84. The first position detection piece 81 is arranged at the connecting point 60 of the extended grounding wire 31 and the original grounding wire 30, for detecting whether the position of the connecting point 60 changes. The second position detection piece 82 is arranged beside the grounding pin 2, for detecting whether the position of the grounding pin 2 changes. The alarm transmitting module 83 is installed on the grounding pin 2 and is in communication connection with the first position detection piece 81 and the second position detection piece 82. The mobile alarm 84 is in communication connection with the alarm transmitting module 83 and is carried by the on-site person in charge 40.

[0069] After the grounding pin 2 reaches the specified depth, the second position detection piece 82 is placed beside the grounding pin 2, the first position detection piece 81 is placed at the connecting point 60 of the extended grounding wire 31 and the original grounding wire 30, the alarm transmitting module 83 is turned on, and the mobile alarm 84 is handed to the on-site person in charge 40 to be carried. When the position of either the grounding pin 2 or the connecting point 60 changes, the corresponding first position detection piece 81 and second position detection piece 82 will send a signal to the alarm transmitting module 83. The alarm transmitting module 83 sends the signal to the mobile alarm 84 wirelessly, so that the on-site person in charge 40 can be warned in time through the mobile alarm 84, so as to avoid the situation that the connecting point 60 of the extended grounding wire 31 and the original grounding wire 30 or the grounding pin 2 is collided by people or animals, and the grounding is not firm, and the safety hazard is eliminated in time.

[0070] It should be noted that the first position detection piece 81 and the second position detection piece 82 can be selected as position sensors. The alarm transmitting module 83 can be in wired connection or wireless connection with the first position detection piece 81 and the second position detection piece 82. The mobile alarm 84 can be in wireless connection with the alarm transmitting module 83. The wired connection and the wireless connection are both prior art, and will not be described here.

[0071] Further, as Figure 1As shown, the electrical connection between the extension grounding wire 31 and the grounding needle 2 is achieved through the connecting assembly 9, which includes a connecting disc 91, a connecting module 92, and a lead-out wire 93. The connecting disc 91 is arranged at the end of the reel 3 away from the motor 32 and is connected to the second end of the extension grounding wire 31. The connecting module 92 is connected to the connecting disc 91. One end of the lead-out wire 93 is connected to the connecting module 92, and the other end of the lead-out wire 93 is connected to the grounding needle 2. The second end of the extension grounding wire 31 is connected to the grounding needle 2 through the connecting disc 91, the connecting module 92, and the lead-out wire 93 in sequence, achieving the transmission of electrical energy. When the reel 3 is winding or unwinding, the second end of the extension grounding wire 31 must also rotate. Therefore, by arranging the connecting assembly 9, the second end of the extension grounding wire 31 is connected to the connecting disc 91. When the reel 3 rotates, the connecting disc 91 rotates with the reel 3 and the second end of the extension grounding wire 31, avoiding the second end of the extension grounding wire 31 from being twisted and protecting the extension grounding wire 31.

[0072] The connecting module 92 can be a carbon brush, which has a built-in sliding contact for transmitting electrical energy and effectively prolonging the service life of the device.

[0073] The working process of the grounding device provided in the embodiment is as follows:

[0074] 1) Electrically connecting the first end of the extension grounding wire 31 to the original grounding wire 30 and connecting the second end of the extension grounding wire 31 to the grounding needle 2 through the connecting disc 91, the connecting module 92, and the lead-out wire 93 in sequence;

[0075] 2) Moving the support 1 and the grounding needle 2 and driving the reel 3 to continuously unwind the first end of the extension grounding wire 31 through the motor 32 until the appropriate soil surface 10 is reached. After inserting the grounding needle 2 at the appropriate position, placing the support 1 on top of the grounding needle 2, and turning on the switch of the power supply 50. If the metal sensor 51 senses that there is metal underground, the sensing switch 52 is triggered to open, disconnecting the circuit between the power supply 50 and the vibration coil 42, stopping the grounding needle 2 from being driven into the ground, and requiring a change of grounding position. If the metal sensor 51 senses that there is no metal underground, the sensing switch 52 remains closed, keeping the circuit between the power supply 50 and the vibration coil 42 connected, and the vibration hammer 41 continues to drive the grounding needle 2 into the ground.

[0076] 3) When the grounding needle 2 reaches the designated depth, a second position detection piece 82 is placed beside it, a first position detection piece 81 is placed at the connection between the extended grounding wire 31 and the original grounding wire 30, the alarm transmitting module 83 is turned on, and the mobile alarm 84 is handed to the on-site responsible person 40 to carry. In use, when the position of any one of the grounding needle 2 and the connection point 60 changes, the corresponding first position detection piece 81 and second position detection piece 82 will send a signal to the alarm transmitting module 83, and the alarm transmitting module 83 will send a signal to the mobile alarm 84 through wireless transmission. The on-site responsible person 40 can be warned through the mobile alarm 84, and the on-site responsible person 40 needs to check in time.

[0077] 4) When the grounding work is completed, the output rod 62 of the needle pulling top 6 gradually extends from the cylinder body 61 until it abuts against the soil surface 10, and then the output rod 62 of the needle pulling top 6 continues to extend. At this time, due to the reaction force of the ground, the needle pulling top 6 lifts the support 1, and the support 1 drives the grounding needle 2 to pull out of the ground, thus easily completing the disassembly work of the grounding needle 2.

[0078] 5) After the grounding needle 2 is pulled out, the winding disc 3 is driven to rotate by the motor 32 to store the extended grounding wire 31. At the same time, the winding disc 3 drives the transmission shaft 71 to rotate through the gear set 72, and when the transmission shaft 71 rotates, the left and right movement of the wire arranging device 73 is realized through the cooperation of the guide groove 711 and the protruding teeth in the wire arranging device 73, so as to drive the extended grounding wire 31 to be neatly wound layer by layer on the winding disc 3, and the extended grounding wire 31 is arranged in order during the winding process.
