[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] With the rapid development of science and technology, the application of electrical equipment is increasing, and people's demand for electricity is becoming more and more extensive. The inspection and normal maintenance of lines and equipment have also increased accordingly. In order to ensure the safety of personnel, one end of the line to be inspected or maintained needs to be grounded. However, in the actual operation process, the length of the original grounding wire 30 is usually limited. In the range it can reach, especially in urban areas, most of the lines are hard ground such as cement ground 20. Due to environmental restrictions, the grounding wire cannot be normally connected to the ground.

[0054] In order to solve the above problems, Figure 1 As shown, this embodiment provides a grounding device, including a bracket 1, a grounding pin 2 and a winding reel 3, the bracket 1 is movably arranged, the grounding pin 2 is configured to be inserted into the mud ground 10, the winding reel 3 is rotatably arranged on the bracket 1, and an extended grounding wire 31 is wound on the winding reel 3, the first end of the extended grounding wire 31 can be electrically connected to the original grounding wire 30, and the second end of the extended grounding wire 31 can be electrically connected to the grounding pin 2.

[0055] When in use, the first end of the extended grounding wire 31 is electrically connected to the original grounding wire 30, and the second end of the extended grounding wire 31 is electrically connected to the grounding pin 2, and then the bracket 1 and the grounding pin 2 are dragged to move, so that the winding drum 3 continuously unwinds the first end of the extended grounding wire 31 until it moves to a suitable muddy ground 10 and then inserts the grounding pin 2, so that the wire can be grounded. It can be seen that the grounding device provided in this embodiment can accommodate an extended grounding wire 31 of sufficient length by setting the winding drum 3, so that the extended grounding wire 31 can be extended to the muddy ground 10 suitable for the grounding pin 2 to be connected, without being restricted by the environment.

[0056] In an optional embodiment, if Figure 1 As shown, the grounding device further includes a motor 32, the motor 32 is powered by a power supply 50, the main body of the motor 32 is fixed on the bracket 1, and the output shaft of the motor 32 is connected to the winding drum 3. In this way, the winding drum 3 can be driven to rotate by the motor 32 to realize the automatic reeling and unreeling of the extended grounding wire 31, thereby improving the degree of automation and saving time and labor.

[0057] In actual use, the soil composition of some dirt floors 10 may not meet the standards or the soil may be too dry, so that the grounding pin 2 fails to fully contact the earth after being grounded, and the grounding resistance is often higher than the standard requirements. Since inspection or maintenance is completed in a race against time, grounding resistance tests are generally not performed on site. Once the grounding resistance is too large, it will bring safety hazards to on-site workers.

[0058] For this reason, Figure 2 As shown, in this embodiment, a resistance reducing agent 22 is provided in the grounding needle 2. The resistance reducing agent 22 can effectively reduce the grounding resistance. When the grounding needle 2 is inserted into the muddy ground 10, the resistance reducing agent 22 is released into the soil, so that the grounding needle 2 is fully in contact with the ground and integrated, thereby reducing the grounding resistance to meet the grounding resistance requirements and reducing safety hazards.

[0059] Furthermore, if Figure 1 As shown, the bracket 1 includes a first mounting frame 11 and a second mounting frame 12. The first mounting frame 11 is U-shaped and has an opening facing upward. The winding reel 3 is arranged across and rotatably on the first mounting frame 11. The second mounting frame 12 is U-shaped and has a mounting cavity 121 inside. The open 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 also includes a hammering assembly 4 located in the installation cavity 121, and the hammering assembly 4 includes a vibration hammer 41, a vibration coil 42 and a reset spring 43. The vibration hammer 41 is located at the bottom of the installation cavity 121, and the vibration coil 42 is arranged around the peripheral side of the vibration hammer 41 and is electrically connected to the power supply 50. One end of the reset spring 43 abuts against the vibration hammer 41, and the other end abuts against the first mounting bracket 11. After the power supply 50 energizes the vibration coil 42, the vibration hammer 41 repeatedly performs an up and down hammering action under the action of the magnetic force of the vibration coil 42 and the elastic force of the reset spring 43, thereby generating a downward pressing force on the grounding pin 2 at the bottom of the second bracket 1, and automatically driving the grounding pin 2 into the muddy ground 10, saving time and effort.

[0061] Furthermore, if Figure 1 and Figure 2As shown, the grounding device also includes a metal detection component 5, which includes a metal sensor 51 and a sensing switch 52. The metal sensor 51 is arranged at the end of the grounding pin 2, and the sensing switch 52 is connected between the vibration coil 42 and the power supply 50 through a wire, and can control the on and off of the circuit between the vibration coil 42 and the power supply 50. The sensing switch 52 is communicatively connected to the metal sensor 51, specifically a wireless connection.

[0062] The metal sensor 51 can sense the presence of metal underground. After inserting the grounding pin 2 at the appropriate position, the bracket 1 is placed on the top of the grounding pin 2, and the switch of the power supply 50 is turned on. If the metal sensor 51 senses the presence of metal underground, the induction switch 52 is triggered to disconnect, so that the circuit between the power supply 50 and the vibration coil 42 is disconnected, and the grounding pin 2 is stopped from being driven into the ground. 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, so that 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. This can effectively prevent the grounding pin 2 from hitting underground hard objects (water supply iron pipes) or piercing possible power circuits or communication circuits when it is driven into the ground, causing secondary accidents and injuries.

[0063] like Figure 1 , Figure 3 and Figure 4 As shown, the bottom of the second mounting bracket 12 is provided with a limiting cavity 122 and a slot 123 connected to the limiting cavity 122, and a limiting pin 21 is provided on the top of the grounding pin 2. The limiting pin 21 can be inserted into the limiting cavity 122 from the slot 123, and is limited in the limiting cavity 122 by rotation. The limiting cavity 122 can be a cylindrical cavity, and the slot 123 is a long strip. The limiting pin 21 is adapted to 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, the grounding pin 2 is first inserted into the appropriate position, and then the bracket 1 is placed on the top of the grounding pin 2. First, ensure that the limiting pin 21 is aligned with the slot 123, so that the limiting pin 21 can be inserted into the limiting cavity 122 from the slot 123, and the disassembly and assembly are more convenient.

[0064] Furthermore, if Figure 1 As shown, the two ends of the bottom of the bracket 1 are provided with a needle puller 6, which can be an electric cylinder. The cylinder body 61 of the needle puller 6 is fixed to the bottom of the bracket 1, and the output rod 62 of the needle puller 6 can extend from the cylinder body 61 and abut against the muddy ground 10. After the grounding work is completed, the output rod 62 of the needle puller 6 gradually extends from the cylinder body 61 until it abuts against the muddy ground 10, and then the output rod 62 of the needle puller 6 continues to extend. At this time, due to the reaction force of the ground, the needle puller 6 lifts the bracket 1, and the bracket 1 drives the grounding pin 2 to be pulled out of the ground, and the removal of the grounding pin 2 is easily completed, avoiding the situation where the grounding pin 2 cannot be pulled out or is bent due to the artificial force not being perpendicular to the ground, saving time and effort.

[0065] Furthermore, if Figure 1 As shown, the grounding device also includes a wire arrangement assembly 7, which includes a transmission shaft 71 and a wire arrangement device 73. The transmission shaft 71 is rotatably arranged on the first mounting frame 11 of the bracket 1. The winding drum 3 is connected to the transmission shaft 71 through a gear set 72. A spiral guide groove 711 is provided on the outer wall of the transmission shaft 71. The wire arrangement device 73 is sleeved on the transmission shaft 71. A convex tooth is convexly provided on the inner wall of the wire arrangement device 73. The convex tooth cooperates with the guide groove 711. The first end of the extended grounding wire 31 is passed through the wire arrangement device 73. After completing the grounding maintenance work and pulling out the grounding pin 2, the winding drum 3 is rotated to store the extended grounding wire 31. At the same time, the winding drum 3 drives the transmission shaft 71 to rotate through the gear set 72. When the transmission shaft 71 rotates, the guide groove 711 cooperates with the convex teeth in the wire arranger 73 to realize the left and right movement of the wire arranger 73, thereby driving the extended grounding wire 31 to be neatly wound up layer by layer on the winding drum 3, and the extended grounding wire 31 is arranged in order during the winding process.

[0066] Specifically, Figure 5 As shown, the gear set 72 includes a first gear 721, a second gear 722, a third gear 723 and a fourth gear 724. The first gear 721 is sleeved on the rotating shaft of the winding drum 3 and connected by a key. The first gear 721 is meshed with the second gear 722 for transmission, the second gear 722 is meshed with the third gear 723 for transmission, the third gear 723 is meshed with the fourth gear 724 for transmission, and the fourth gear 724 is sleeved on the transmission shaft 71 and connected by a key. Thus, the rotation of the transmission shaft 71 is realized through the meshing transmission of multiple gears. This gear transmission method has stable transmission, accurate transmission ratio, reliable operation, compact structure and high efficiency.

[0067] Since the grounding device is used outdoors, the connection point 60 between the extended grounding wire 31 and the original grounding wire 30 or the grounding pin 2 is easily hit by humans or animals, resulting in unstable grounding, which will bring potential safety hazards to on-site workers.

[0068] For this reason, Figure 1As shown, in this embodiment, the grounding device also includes a position detection component 8, which includes a first position detection component 81, a second position detection component 82, an alarm transmitting module 83 and a mobile alarm 84. The first position detection component 81 is arranged at the connection point 60 between the extended grounding wire 31 and the original grounding wire 30, and is used to detect whether there is a position change at the connection point 60. The second position detection component 82 is arranged beside the grounding pin 2, and is used to detect whether there is a position change at the grounding pin 2. The alarm transmitting module 83 is installed on the grounding pin 2, and is communicated with the first position detection component 81 and the second position detection component 82. The mobile alarm 84 is communicated with the alarm transmitting module 83 and is carried by the on-site responsible person 40.

[0069] After the grounding needle 2 reaches the specified depth, the second position detection member 82 is placed beside it, the first position detection member 81 is placed at the connection point 60 between the extended grounding wire 31 and the original grounding wire 30, the alarm transmission module 83 is turned on, and the mobile alarm 84 is handed over to the on-site responsible person 40 to carry with him. When the position of any one of the grounding needle 2 and the connection point 60 changes, the corresponding first position detection member 81 and second position detection member 82 will send a signal to the alarm transmission module 83, and the alarm transmission module 83 will send the signal to the mobile alarm 84 via wireless. The mobile alarm 84 can send a warning message to the on-site responsible person 40 to avoid the situation where the connection point 60 between the extended grounding wire 31 and the original grounding wire 30 or the grounding needle 2 is not grounded after being hit by humans or animals, and eliminate safety hazards in time.

[0070] It should be noted that the first position detection component 81 and the second position detection component 82 can be optionally selected as position sensors, the alarm transmitting module 83 and the first position detection component 81 and the second position detection component 82 can be connected by wire or wirelessly, and the mobile alarm 84 and the alarm transmitting module 83 can be connected by wirelessly, wherein both wired connection and wireless connection methods are existing technologies and will not be repeated here.

[0071] Furthermore, if Figure 1As shown, the extended ground wire 31 is electrically connected to the ground pin 2 through the connection assembly 9, and the connection assembly 9 includes a connection disk 91, a connection module 92 and a lead wire 93. The connection disk 91 is arranged at one end of the winding drum 3 away from the motor 32 and is connected to the second end of the extended ground wire 31. The connection module 92 is connected to the connection disk 91, one end of the lead wire 93 is connected to the connection module 92, and the other end of the lead wire 93 is connected to the ground pin 2. The second end of the extended ground wire 31 is connected to the ground pin 2 through the connection disk 91, the connection module 92 and the lead wire 93 in sequence to realize the transmission of electric energy. When the winding drum 3 is reeled and unreeled, the second end of the extended ground wire 31 must also rotate with it. Therefore, by setting the connection assembly 9, the second end of the extended ground wire 31 is connected to the connection disk 91. When the winding drum 3 rotates, the connection disk 91 will rotate with the winding drum 3 and the second end of the extended ground wire 31 to avoid the second end of the extended ground wire 31 from twisting and protect the extended ground wire 31.

[0072] The connection module 92 may be a carbon brush with a built-in sliding contact for transmitting electrical energy, thereby effectively extending the life of the device.

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

[0074] 1) The first end of the extended grounding wire 31 is electrically connected to the original grounding wire 30, and the second end of the extended grounding wire 31 is connected to the grounding pin 2 through the connection plate 91, the connection module 92 and the lead wire 93 in sequence;

[0075] 2) Drag the bracket 1 and the grounding pin 2 to move, and drive the winding reel 3 through the motor 32 to continuously unwind and extend the first end of the grounding wire 31 until it moves to a suitable muddy ground 10. After inserting the grounding pin 2 at a suitable position, place the bracket 1 on 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 triggering induction switch 52 is disconnected, so that the circuit between the power supply 50 and the vibration coil 42 is disconnected, and the grounding pin 2 is stopped from being driven into the ground. 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, so that 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.

[0076] 3) After the grounding pin 2 reaches the specified depth, the second position detection member 82 is placed beside it, the first position detection member 81 is placed at the connection between the extended grounding wire 31 and the original grounding wire 30, the alarm transmission module 83 is turned on, and the mobile alarm 84 is handed over to the on-site responsible person 40 to carry with him. During use, when the position of any one of the grounding pin 2 and the connection point 60 changes, the corresponding first position detection member 81 and second position detection member 82 will send a signal to the alarm transmission module 83, and the alarm transmission module 83 will send the signal to the mobile alarm 84 via wireless, so that the mobile alarm 84 can send a warning message to the on-site responsible person 40, and the on-site responsible person 40 needs to go to the site for inspection in time.

[0077] 4) After the grounding work is completed, the output rod 62 of the needle puller 6 gradually extends out of the cylinder body 61 until it abuts against the mud ground 10, and then the output rod 62 of the needle puller 6 continues to extend. At this time, due to the reaction force of the ground, the needle puller 6 lifts the bracket 1, and the bracket 1 drives the grounding pin 2 to be pulled out of the ground, and the removal of the grounding pin 2 is easily completed.

[0078] 5) After the grounding pin 2 is pulled out, the motor 32 drives the winding drum 3 to rotate to store the extended grounding wire 31. At the same time, the winding drum 3 drives the transmission shaft 71 to rotate through the gear set 72. When the transmission shaft 71 rotates, the guide groove 711 cooperates with the convex teeth in the wire arranger 73 to realize the left and right movement of the wire arranger 73, thereby driving the extended grounding wire 31 to be neatly wound up layer by layer on the winding drum 3, and the extended grounding wire 31 is arranged in order during the winding process.
