[0002] This application claims priority to Chinese patent application No. 202310080642.6, filed on January 16, 2023, entitled “Grounding Wire Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to the field of grounding wire equipment technology, and in particular to a grounding wire device. Background Technology

[0004] Grounding wires are a safety tool frequently used in electrical work. When electrical equipment is shut down for maintenance or inspection, grounding wires must be installed on all sides where power may be supplied, on electrical equipment that may generate induced current or store charge, in order to prevent damage from sudden power surges, induced current, and residual charge. This ensures that a short circuit can be safely conducted and the current can be introduced to the ground in the event of a sudden power surge.

[0005] The existing old substations mostly use ordinary mechanical grounding stakes. When grounding the grounding wire, tools can only be used to wrap the grounding wire around the mechanical grounding stake. If the grounding wire is too taut, it is easy to fall off the mechanical grounding stake. Therefore, it is urgent to modify the existing mechanical grounding stakes to ensure that the grounding wire is firmly connected to the mechanical grounding stake. Summary of the Invention

[0006] The main objective of this invention is to provide a grounding wire device that facilitates the retrofitting of existing grounding stakes.

[0007] To achieve the above objectives, the present invention proposes a grounding wire device, comprising a passive grounding wire stake lock and an intelligent grounding wire connector; wherein, the passive grounding wire stake lock is fixedly installed on the grounding wire stake, and includes a support base and a control module, an unlocking / locking module, two wireless charging modules, and an energy storage module installed on the support base. The energy storage module is electrically connected to the control module, the unlocking / locking module, and the two wireless charging modules. The unlocking / locking module has a locked state and an unlocked state. The two wireless charging modules are spaced apart at a first position and a second position on the support base. The intelligent grounding wire connector is fixedly connected to the grounding end of the temporary grounding wire, and includes a grounding wire connector body and a main control module and a wireless power supply module installed on the grounding wire connector body. The grounding wire connector body is movably connected to the support base, and the main control module is connected to the control module, the unlocking / locking module, and the wireless charging module. The wireless power supply module is electrically connected and can communicate with the control module. Before the smart ground wire is plugged into the ground wire stake, when the wireless power supply module overlaps with the wireless charging module at the first position, the main control module controls the wireless power supply module to supply power to the wireless charging module at the corresponding position and can control the unlocking / locking module to switch to the unlocked state. After the smart ground wire is plugged into the ground wire stake, when the wireless power supply module overlaps with the wireless charging module at the second position, the main control module controls the wireless power supply module to supply power to the wireless charging module at the corresponding position and controls the unlocking / locking module to switch to the locked or unlocked state. When the wireless power supply module overlaps with any of the wireless charging modules, the energy storage module acquires and stores enough electrical energy to support the unlocking / locking module to lock at least once.

[0008] In some embodiments of the present invention, the energy storage module stores energy when the wireless power supply module supplies power to any of the wireless charging modules, the control module and the unlocking / locking module operate under the power supply of the energy storage module, and the control module controls the unlocking / locking module to switch states so that the passive grounding stake lock returns to the locked state after the smart grounding head is removed or accidentally disengaged in the first position.

[0009] In some embodiments of the present invention, when the main control module detects that the wireless power supply module is supplying power, the main control module controls the energy storage module to store energy, and the control module is also used to control the unlocking module to switch states.

[0010] After the unlocking module has been in the unlocked state for a certain period of time, the control module controls the energy storage module to supply power to the unlocking module. The control module also controls the unlocking module to switch to the locked state.

[0011] In some embodiments of the present invention, the passive grounding stake lock further includes a timing module, which is electrically connected to the control module and is used to detect the unlocking duration when the unlocking module switches to the unlocking state;

[0012] When the smart grounding head is installed on the passive grounding stake lock, when the timing module detects that the unlocking time of the unlocking module switching to the unlocking state is greater than the first preset unlocking time, the control module controls the energy storage module to supply power to the unlocking module, and the control module also controls the unlocking module to switch to the locked state;

[0013] When the smart ground wire head is removed from the passive ground wire stake lock, when the timing module detects that the unlocking time of the unlocking module switching to the unlocked state is greater than the second preset unlocking time, the control module controls the energy storage module to supply power to the unlocking module, and the control module also controls the unlocking module to switch to the locked state.

[0014] In some embodiments of the present invention, the energy storage module is an energy storage capacitor.

[0015] In some embodiments of the present invention, the support base is provided with a code chip, and the smart ground wire head is provided with a code reading module electrically connected to the main control module. The code reading module is used to read the identity information of the code chip.

[0016] When the wireless power supply module overlaps with any of the wireless charging modules, the main control module controls the code reading module to read the identity information of the code chip;

[0017] When the identity information matches the preset identity information, the main control module controls the wireless power supply module to supply power to the corresponding wireless charging module.

[0018] In some embodiments of the present invention, the support base includes a fixing part and a connecting part. The fixing part extends vertically, one end of the connecting part is connected to the fixing part, and the other end of the connecting part extends horizontally away from the fixing part.

[0019] The fixing part is detachably connected to the grounding stake. The control module and the unlocking module are both located in the fixing part. The two wireless charging modules are located in the connecting part. The two wireless charging modules are also arranged at intervals along the extension direction of the connecting part. The grounding head body can move relative to the connecting part along the extension direction of the connecting part.

[0020] In some embodiments of the present invention, the passive grounding stake lock further includes a clamping member, which is detachably connected to the fixing part, and the clamping member and the fixing part are used to jointly fix and clamp the grounding stake.

[0021] In some embodiments of the present invention, the clamping member has a recessed receiving groove on the surface facing the fixing part, and one wall of the receiving groove forms a clearance opening. The receiving groove is used to receive one end of the grounding stake, and the clearance opening is used to allow the other end of the grounding stake to extend out.

A plug-in boss is provided at one end of the conductive copper sleeve adjacent to the stake hole. The plug-in boss is used to plug into and cooperate with the stake hole. The end of the lock rod away from the grounding wire head body can pass through the conductive copper sleeve and the stake hole.

[0024] In some embodiments of the present invention, the inner diameter of the conductive copper sleeve is smaller than the diameter of the pile hole, and the outer diameter of the locking rod is adapted to the inner diameter of the conductive copper sleeve; and / or, the end of the conductive copper sleeve away from the pile hole of the ground wire is folded outward to form a flange that abuts against the outer edge of the first clearance hole.

[0025] In some embodiments of the present invention, the grounding device further includes a butterfly nut for threaded connection with one end of the locking rod passing through the first clearance hole and the pile hole.

[0026] In some embodiments of the present invention, the fixing part is provided with a mounting cavity and a first clearance hole, the mounting cavity is located on the periphery of the first clearance hole, the first clearance hole is used to connect the mounting cavity and the first clearance hole, and the outer peripheral wall of the locking rod is provided with an upper locking part;

[0027] The unlocking and locking module is installed in the mounting cavity. When the unlocking and locking module is in the locked state, the unlocking and locking module extends at least partially into the first clearance hole and applies a constraint to the upper locking part. When the unlocking and locking module is in the unlocked state, the unlocking and locking module located in the first clearance hole can be partially withdrawn from the first clearance hole to remove the constraint on the upper locking part.

[0028] In some embodiments of the present invention, the locking / unlocking module includes an electronic lock cylinder, a transmission shaft, an elastic reset element, and a locking pin; wherein,

[0029] The locking pin has a locking end and a limiting end that are disposed opposite to each other. The locking pin is movably installed in the mounting cavity. The locking end of the locking pin can extend from the first clearance hole into the first clearance hole or retract from the first clearance hole.

[0030] The elastic reset member is installed in the mounting cavity, and the elastic reset member acts on the locking pin so that the locking end of the locking pin always remains in the state of extending from the first clearance hole into the first clearance hole.

[0031] The transmission shaft is located on the side of the locking pin away from the first clearance hole. The transmission shaft includes a connecting section and a supporting section. The connecting section is rotatably installed in the mounting cavity. The supporting section protrudes laterally from the connecting section. As the connecting section rotates, the supporting section has a locked position that abuts against the limiting end of the locking pin and an unlocked position that is misaligned with the limiting end of the locking pin.

[0032] The electronic lock cylinder is installed in the mounting cavity, and the output end of the electronic lock cylinder is connected to the connecting section of the transmission shaft to drive the connecting section of the transmission shaft to rotate.

[0033] In some embodiments of the present invention, the fixing part is provided with a second clearance hole communicating with the mounting cavity, and the unlocking and locking module further includes a mechanical lock cylinder, which is installed in the mounting cavity. The keyhole of the mechanical lock cylinder is exposed from the second clearance hole, and the output end of the mechanical lock cylinder is connected to the connecting section of the transmission shaft to drive the connecting section of the transmission shaft to rotate.

[0034] In some embodiments of the present invention, the passive grounding stake lock further includes a dust cover, which is connected to the fixing part and is also used to cover the second clearance hole.

[0035] In some embodiments of the present invention, the passive grounding stake lock further includes a sealing gasket, which is disposed between the fixing part and the dust cover. The sealing gasket is used to cover the second clearance hole and also to seal the gap between the dust cover and the support base.

[0036] In some embodiments of the present invention, a sliding groove is recessed on the upper surface of the connecting part, the sliding groove extends along the extending direction of the connecting part, and two tactile beads are provided on the groove wall of the sliding groove, the distance between the two tactile beads in the extending direction of the connecting part is equal to the distance between the two wireless charging modules in the extending direction of the connecting part.

[0037] The ground wire head body is slidably connected to the sliding groove. The ground wire head body has a positioning hole recessed on the surface of the two tactile beads. When the positioning hole is engaged with any of the two tactile beads, the wireless power supply module is overlapped with the wireless charging module at the corresponding position.

[0038] In some embodiments of the present invention, two signal transmitting devices are provided on the upper surface of the connecting part, the two signal transmitting devices are arranged at intervals along the extension direction of the connecting part, and the distance between the two signal transmitting devices in the extension direction of the connecting part is equal to the distance between the two wireless charging modules in the extension direction of the connecting part.

[0039] The ground wire head body is equipped with a signal receiving device electrically connected to the main control module. After the signal receiving device is aligned with any of the two signal transmitting devices, it can receive the activation signal emitted by the corresponding signal transmitting device. After the signal receiving device receives the activation signal, the main control module controls the wireless power supply module to supply power to the corresponding wireless charging module.

[0040] In some embodiments of the present invention, the intelligent grounding head further includes an activation button, which is electrically connected to the main control module and is used to activate the main control module.

[0041] In this invention, a passive grounding stake lock is fixedly connected to a grounding stake, and a smart grounding head is electrically connected to a grounding wire. The passive grounding stake lock can lock or unlock the smart grounding head, allowing it to be fixed to or removed from the lock. This facilitates the connection or disassembly of the grounding wire and the grounding stake. Furthermore, existing grounding stakes can be modified by adding the grounding device of this invention, simplifying the connection between the existing grounding stake and the grounding wire. In addition, the smart grounding head in this application is located above the support base. This design allows the operator to hold the smart grounding head during assembly or disassembly, facilitating locking and unloading. In the grounding device of this embodiment, the passive grounding stake lock included in the grounding device is a passive device. Therefore, it is not necessary to connect the passive grounding stake lock to a power supply line or replace the battery. The energy storage module included in the passive grounding stake lock stores electrical energy to support the unlocking and locking module to lock at least once. While ensuring that the passive grounding stake lock can perform at least one unlocking and locking operation, it does not need to be connected to a power supply structure, making the passive grounding stake lock more suitable for outdoor environments and ensuring its durability. In the grounding device of this embodiment, two wireless charging modules are spaced apart at the first and second positions of the support base. When it is necessary to install the smart grounding head onto the passive grounding stake lock, the grounding head body first moves until the wireless power supply module overlaps with the wireless charging module at the first position. The main control module controls the unlocking and locking module to switch to the unlocked state, facilitating the subsequent movement of the grounding head body towards the unlocking and locking module. Subsequently, when the grounding head moves to the point where the wireless power supply module and the wireless charging module at the second position overlap, the main control module controls the unlocking / locking module to switch to the locked state, thereby enabling the smart grounding head to be installed onto the passive grounding stake lock. During this process, when the wireless power supply module overlaps with the wireless charging modules at the first and second positions, the main control module performs identity verification respectively, and controls the unlocking / locking module to switch states differently when the wireless charging modules at different positions are triggered, ensuring the accuracy of installing the smart grounding head onto the passive grounding stake lock.

[0058] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0060] Furthermore, the use of terms such as "first" and "second" in this invention is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art.

[0061] Please see Figure 1 This invention proposes a grounding wire device 1000, which includes a passive grounding stake lock 100 and a smart grounding head 200. The passive grounding stake lock 100 is used for detachable connection with the grounding stake, and the smart grounding head 200 is used for electrical connection with the grounding wire. In this embodiment, the smart grounding head 200 is fixedly connected to the grounding end of the temporary grounding wire. The passive grounding stake lock 100 and the smart grounding head 200 cooperate to lock or unlock the smart grounding head 200, thereby realizing the electrical connection between the grounding wire and the grounding stake. With this configuration, the existing grounding stake can be modified by adding the lock.

[0062] Please refer to the following: Figure 2 and Figure 9 In some embodiments, the passive grounding stake lock 100 is fixedly installed on the grounding stake. The passive grounding stake lock 100 includes a support base 110, a control module (not shown), an unlocking / locking module 120, and two wireless charging modules 130. The control module, the unlocking / locking module 120, and the wireless charging modules 130 are all mounted on the support base 110. The support base 110 is used to electrically connect to the grounding stake. The control module is electrically connected to the unlocking / locking module 120 and the two wireless charging modules 130. The unlocking / locking module 120 has a locked state and an unlocked state. The two wireless charging modules 130 are also spaced apart in the horizontal direction.

[0063] In this invention, the passive grounding stake lock 100 is fixedly connected to the grounding stake, and the intelligent grounding head 200 is electrically connected to the grounding wire. The passive grounding stake lock 100 can lock or unlock the intelligent grounding head 200, so that the intelligent grounding head 200 can be fixed to the passive grounding stake lock 100 or removed from the passive grounding stake lock 100. This facilitates the connection or disassembly between the grounding wire and the grounding stake. Furthermore, the existing grounding stake can be modified by adding the grounding wire device of this invention, making the cooperation between the existing grounding stake and the grounding wire simpler.

[0064] Meanwhile, the wireless power supply modules 130 in this application are spaced out, and the smart ground wire head 200 stops moving when it reaches a certain fixed position, so that the wireless power supply module 130 can stably supply power to the wireless power receiving module 230, thereby ensuring stable power reception of the wireless power receiving module 230. In addition, with the two wireless power receiving modules 230 spaced out, the passive ground wire stake lock 100 does not need to be in a constantly energized state. The unlocking and locking module can still remain unlocked for a certain period of time when the power is off, thereby ensuring that the smart ground wire head 200 can be successfully locked on the passive ground wire stake lock 100.

[0065] Furthermore, the intelligent grounding head 200 in this application is located above the support base 110 of the passive grounding stake lock 100. This arrangement makes it convenient for the operator to hold the intelligent grounding head 200 during the process of assembling the intelligent grounding head 200 to the support base 110 or removing the intelligent grounding head 200 from the support base 110, thereby facilitating the locking and unlocking of the intelligent grounding head 200.

[0066] Please refer to the following: Figure 2 The intelligent grounding head 200 includes a grounding head body 210, a main control module 220, and a wireless power supply module 230. The grounding head body 210 is used to electrically connect to the grounding wire. The grounding head body 210 is also movably connected to the support base 110. The grounding head body 210 can be locked or unlocked by the unlocking module 120. The main control module 220 and the wireless power supply module 230 are both installed on the grounding head body 210. The main control module 220 is electrically connected to the wireless power supply module 230. The main control module 220 can also communicate with the unlocking module 120.

[0067] In this embodiment, the grounding device 1000 includes a passive grounding stake lock 100 and a smart grounding head 200. The passive grounding stake lock 100 includes a support base 110 and a control module, an unlocking / locking module 120, two wireless charging modules 130, and an energy storage module 300 mounted on the support base 110. The energy storage module 300 is electrically connected to the control module, the unlocking / locking module 120, and the two wireless charging modules 130. The unlocking / locking module 120 has a locked state and an unlocked state. The two wireless charging modules 130 are spaced apart at a first position and a second position on the support base 110. The smart grounding head 200 includes a grounding head body 210 and a main control module 220 and a wireless power supply module 230 mounted on the grounding head body 210. The grounding head body 210 is movably connected to the support base 110. The main control module 220 is electrically connected to the wireless power supply module 230. The main control module 220 can also communicate with the control module.

[0068] Before the smart grounding head 200 is plugged into the grounding stake, the grounding head body 210 moves horizontally relative to the support base 110 until the wireless power supply module 230 overlaps with the wireless charging module 130 at the first position. Then, the main control module 220 controls the wireless power supply module 230 to supply power to the wireless charging module 130 at the corresponding position, and can control the unlocking module 120 to switch to the unlocked state.

[0069] After the smart grounding head 200 is plugged into the grounding stake, the grounding head body 210 moves horizontally relative to the support base 110 until the wireless power supply module 230 overlaps with the wireless charging module 130 at the second position. Then, the main control module 220 controls the wireless power supply module 230 to supply power to the wireless charging module 130 at the corresponding position, and controls the locking / unlocking module 120 to switch to the locked or unlocked state.

[0070] In this embodiment, when the wireless power supply module 230 overlaps with any wireless charging module 130, the energy storage module 300 acquires and stores enough electrical energy to support the unlocking module 120 to perform at least one lockout.

[0071] In this embodiment, the energy storage module 300 is an energy storage capacitor.

[0072] In the grounding device 1000 of this embodiment, the passive grounding stake 100 included in the grounding device 1000 is a passive device. Therefore, it is not necessary to connect the passive grounding stake 100 to a power supply line or replace the battery. The energy storage module 300 included in the passive grounding stake 100 stores electrical energy to support the locking / unlocking module 120 to lock at least once. While ensuring that the passive grounding stake 100 can perform at least one locking / unlocking operation, it is not necessary to connect to a power supply structure, making the passive grounding stake 100 more suitable for outdoor environments and ensuring the durability of the passive grounding stake 100. In the grounding device 1000 of this embodiment, two wireless charging modules 130 are spaced apart at the first and second positions of the support base 110. When the smart grounding head 200 needs to be installed onto the passive grounding lock 100, the grounding head body 210 first moves until it overlaps with the wireless power supply module 230 and the wireless charging module 130 at the first position. The main control module 220 then controls the unlocking module 120 to switch to the unlocked state, facilitating the subsequent movement of the grounding head body 210 towards the unlocking module 120. Afterward, when the grounding head body 210 moves until it overlaps with the wireless power supply module 230 and the wireless charging module 130 at the second position, the main control module 220 controls the unlocking module 120 to switch to the locked state, thereby enabling the smart grounding head 200 to be installed onto the passive grounding lock 100. During the above process, when the wireless power supply module 230 overlaps with the wireless charging module 130 at the first and second positions, the main control module 220 performs identity verification respectively, and performs different state switching control on the unlocking and locking module 120 when the wireless charging module 130 at different positions is triggered, so as to ensure the accuracy of installing the smart ground wire head 200 onto the passive ground wire stake lock 100.

[0073] After the ground wire head body 210 is placed on the support base 110, it can also move horizontally relative to the support base 110. For ease of description, the position of one of the two wireless charging modules 130 is defined as the first position, and the position of the other wireless charging module 130 is defined as the second position. When the ground wire head body 210 moves to the first position or the second position, the wireless power supply module 230 on the ground wire head body 210 coincides with the wireless charging module 130 at the corresponding position.

[0074] Please see Figure 3 and Figure 4When it is necessary to lock the smart ground wire head 200 to the passive ground wire stake lock 100, a horizontal force is applied to the ground wire head body 210 to drive the ground wire head body 210 to move relative to the support base 110 to the first position. At this time, the wireless power supply module 230 coincides with the wireless charging module 130 located in the first position. The main control module 220 controls the wireless power supply module 230 to supply power to the wireless charging module 130 located in the first position. At this time, both the control module and the unlocking module 120 are activated. The main control module 220 also establishes a wireless communication connection (Bluetooth, WiFi, etc.) with the activated control module. The main control module 220 sends an unlocking command to the control module. After receiving the unlocking command, the control module controls the unlocking module 120 to switch to the unlocked state. At this time, the ground wire head body 210 is not constrained by the unlocking module 120 and can continue to move horizontally relative to the support base 110.

[0075] Please see Figure 3 and Figure 4 During the movement of the ground wire head body 210 from the first position to the second position, the wireless power supply module 230 and the two wireless charging modules 130 are misaligned. At this time, the unlocking module 120 is still in the unlocked state. When the ground wire head body 210 moves to the second position, the wireless power supply module 230 coincides with the wireless charging module 130 located in the second position. The main control module 220 controls the wireless power supply module 230 to supply power to the wireless charging module 130 located in the second position. At this time, both the control module and the unlocking module 120 are activated. The main control module 220 also establishes a wireless communication connection with the activated control module. The main control module 220 sends a locking command to the control module. After receiving the locking command, the control module controls the unlocking module 120 to switch to the locked state. At this time, the ground wire head body 210 is locked on the support base 110. At the same time, the ground wire head body 210 is also electrically connected to the ground wire stake, thereby realizing the electrical connection between the ground wire and the passive ground wire stake lock 100.

[0076] When the smart grounding head 200 needs to be unlocked from the passive grounding stake lock 100, since the grounding head body 210 is locked on the support base 110 and is in the second position, the wireless power supply module 230 and the wireless charging module 130 in the second position are overlapped. The main control module 220 controls the wireless power supply module 230 to supply power to the wireless charging module 130 in the second position. At this time, both the control module and the unlocking module 120 are activated. A wireless communication connection is established between the main control module 220 and the control module. The main control module 220 sends an unlocking command to the control module. At this time, the control module controls the unlocking module 120 to switch to the unlocked state. At this time, the grounding head body 210 is not constrained by the unlocking module 120 and can move horizontally relative to the support base 110.

[0077] During the movement of the ground wire head 210 from the second position to the first position, the wireless power supply module 230 and the two wireless charging modules 130 are misaligned. At this time, the unlocking module 120 is still in the unlocked state. When the ground wire head 210 moves to the first position, the wireless power supply module 230 and the wireless charging module 130 located in the first position are overlapped. The main control module 220 controls the wireless power supply module 230 to supply power to the wireless charging module 130 located in the first position. At this time, both the control module and the unlocking module 120 are activated. A wireless communication connection is established between the main control module 220 and the control module. The main control module 220 sends a locking command to the control module. At this time, the control module controls the unlocking module 120 to switch to the locked state. At this time, the ground wire head 210 is no longer constrained by the unlocking module 120 and completes the unlocking. At the same time, when the unlocking module 120 switches to the locked state, it also ensures that the mismatched smart ground wire head 200 cannot be used with it.

[0078] Considering that when the wireless power supply module 230 supplies power to the wireless charging module 130, the wireless charging module 130 may experience unstable power supply to the control module and the unlocking / locking module 120 at the same time, in some embodiments of the present invention, the grounding device 1000 further includes an energy storage module 300, which may be a capacitor, a battery, etc., and is electrically connected to the control module, the unlocking / locking module 120, and the two wireless charging modules 130.

[0079] In some embodiments, the energy storage module 300 stores energy when the wireless power supply module 230 supplies power to any wireless charging module 130. The control module and the unlocking / locking module 120 operate under the power supply of the energy storage module 300. The control module controls the unlocking / locking module 120 to switch states so that the passive grounding stake lock 100 can be restored to the locked state after the smart grounding head 200 is removed or accidentally dislodged in the first position.

[0080] The energy storage module 300 can directly supply power to the control module and the unlocking / locking module 120. That is, the two wireless charging modules 130 are electrically connected to the main control module 220 and the unlocking / locking module 120 through the energy storage module 300. When the wireless power supply module 230 supplies power to the two wireless charging modules 130, the energy storage module 300 first stores energy, and then the energy storage module 300 supplies power to the control module and the unlocking / locking module 120. This setting ensures that the control module and the unlocking / locking module 120 can work under a stable voltage, thereby avoiding the problem of abnormal operation of the control module and the unlocking / locking module 120 due to insufficient power supply.

[0081] The energy storage module 300 can also serve as a backup power source to supply power to the control module and the unlocking / locking module 120. That is, the two wireless charging modules 130 are directly electrically connected to the control module, the unlocking / locking module 120, and the energy storage module 300. The energy storage module 300 is also electrically connected to the control module and the unlocking / locking module 120. When the two wireless charging modules 130 overlap with the wireless power supply module 230, they can directly supply power to the control module, the unlocking / locking module 120, and the energy storage module 300.

[0082] The specific control process is as follows: When the main control module 220 detects that the wireless power supply module 230 is supplying power to the overlapping wireless charging module 130, the control module is activated under the power supply of the wireless charging module 130. At this time, the main control module 220 can establish a wireless communication connection with the control module. The main control module 220 sends an energy storage command to the control module. After receiving the energy storage command, the control module controls the energy storage module 300 to store energy.

[0083] Based on the technical solution of using the energy storage module 300 as a backup power source to supply power to the control module and the unlocking / locking module 120, after the unlocking / locking module 120 has been in the unlocked state for a certain period of time, the control module controls the energy storage module 300 to supply power to the unlocking / locking module 120. That is to say, at this time, regardless of whether the wireless charging module 130 overlaps with the wireless power supply module 230, the unlocking / locking module 120 is in the activated state, and the control module controls the unlocking / locking module 120 to switch to the locked state. This avoids the passive grounding stake lock 100 being in a state where other smart grounding heads can be inserted. At the same time, limiting the time that the unlocking / locking module 120 is in the unlocked state also helps to ensure the efficiency of installing and removing smart grounding heads.

[0084] Furthermore, the passive grounding stake lock 100 also includes a timing module (not shown), which is electrically connected to the control module and the energy storage module 300. The timing module can be directly connected to the energy storage module 300, or it can be connected to the energy storage module 300 through the control module to ensure that the timing module remains operational when the wireless charging module 130 and the wireless power supply module 230 are misaligned, in order to record the unlocking duration of the unlocking module 120 in the unlocked state.

[0085] It should be noted that the locking / unlocking module 120 needs to be switched to the unlocked state during both the process of the smart ground wire head locking onto the passive ground wire stake lock 100 and the process of the smart ground wire head being disassembled from the passive ground wire stake lock 100. For ease of understanding, the following two specific embodiments will be used to illustrate this in detail:

[0086] When the smart grounding head is installed onto the passive grounding stake lock 100, that is, when the smart grounding head is locked onto the passive grounding stake lock 100, the unlocking module needs to switch from the locked state to the unlocked state. The timing module starts timing when the unlocking module switches to the unlocked state. When the timing module detects that the unlocking time of the unlocking module in the unlocked state is longer than a first preset time, the control module controls the energy storage module 300 to supply power to the unlocking module 120, and the control module also controls the unlocking module 120 to switch back to the locked state. In some embodiments, when the smart grounding head is installed onto the passive grounding stake lock 100, the smart grounding head can obtain the identity information of the grounding stake through wireless communication with the grounding stake.

[0087] When the smart ground wire head is removed from the passive ground wire lock 100, the unlocking module also needs to switch from the locked state to the unlocked state. The timing module starts timing when the unlocking module switches to the unlocked state. When the timing module detects that the unlocking time of the unlocking module in the unlocked state is greater than the second preset time, the control module controls the energy storage module 300 to supply power to the unlocking module 120. The control module also controls the unlocking module 120 to switch to the locked state.

[0088] It should be noted that the passive grounding stake lock 100 typically needs to be used with a matching smart grounding head 200. To avoid using the passive grounding stake lock 100 with an incompatible smart grounding head 200, in some embodiments of the present invention, the grounding device 1000 is further provided with a chip (not shown) and a code reading module (not shown), the chip being disposed on the support base 110. In this embodiment, the chip is a radio frequency identification (RFID) chip; in other embodiments, the chip may be a chip employing other identification technologies. The chip carries identification information, and the code reading module is disposed on the grounding head body 210. The code reading module can read the identification information on the chip, which may be nameplate information, QR code, serial number, barcode, etc. The main control module 220 is also electrically connected to the code reading module, and the main control module 220 can control the operation of the code reading module.

[0089] Specifically, when the wireless power supply module 230 overlaps with any wireless charging module 130, the main control module 220 controls the code reading module to read the identity information on the code chip. When the identity information read by the code reading module matches the preset identity information, the main control module 220 controls the wireless power supply module 230 to supply power to the corresponding wireless charging module 130. At this time, both the control module and the unlocking / locking module 120 are activated, which facilitates the main control module 220 to send control commands to the control module and execute subsequent work. This setting avoids the connection of the smart grounding head 200 that is incompatible with the passive grounding stake lock 100.

[0090] It should be noted that when the grounding device 1000 is equipped with an energy storage module 300, a timing module, a chip, and a code reading module, when the smart grounding head is locked onto the passive grounding stake lock 100, the main control module 220 first controls the code reading module to read the identity information on the chip. When the identity information read by the code reading module matches the preset identity information, the main control module 220 controls the wireless power supply module 230 to supply power to the corresponding wireless charging module 130. At this time, the control module, the unlocking module 120, the energy storage module 300, and the timing module are all activated. The main control module 220 establishes a wireless communication connection with the control module. The control module controls the unlocking module 120 to switch to the unlocked state. The timing module starts timing when the unlocking module switches to the unlocked state. When the timing module detects that the unlocking time of the unlocking module in the unlocked state is greater than the first preset time, the control module controls the energy storage module 300 to supply power to the unlocking module 120. The control module also controls the unlocking module 120 to switch to the locked state.

[0091] When the smart ground wire is removed from the passive ground wire lock 100, the main control module 220 first controls the wireless power supply module 230 to supply power to the wireless charging module 130 at the corresponding position. The control module, the unlocking / locking module 120, the energy storage module 300, and the timing module are all activated at this time. The main control module 220 establishes a wireless communication connection with the control module. The control module controls the unlocking / locking module 120 to switch to the unlocked state. The timing module starts timing when the unlocking module switches to the unlocked state. When the timing module detects that the unlocking time of the unlocking module in the unlocked state is greater than the second preset time, the control module controls the energy storage module 300 to supply power to the unlocking / locking module 120. The control module also controls the unlocking / locking module 120 to switch to the locked state.

[0092] It should be noted that the support base 110 has many possible structures. It can be T-shaped, L-shaped, or other shapes, which will not be listed here. Please refer to some embodiments of the present invention. Figure 1 The support base 110 includes a fixing part 111 and a connecting part 112. The fixing part 111 extends vertically, one end of the connecting part 112 is connected to the fixing part 111, and the other end of the connecting part 112 extends horizontally away from the fixing part 111. That is, the overall outline of the support base 110 is L-shaped.

[0093] The fixing part 111 and the connecting part 112 can be connected by welding, or they can be connected by screws, bolts or other connectors. The fixing part 111 is detachably connected to the grounding stake. The control module and the unlocking module 120 are located on the fixing part 111. Two wireless charging modules 130 are located on the connecting part 112. The two wireless charging modules 130 are also arranged at intervals along the extension direction of the connecting part 112. The connecting part 112 is movably connected to the grounding head body 210. With this configuration, only a force needs to be applied to the grounding head body 210 in the horizontal direction to push the grounding head body 210 to move relative to the connecting part 112, which facilitates the movement of the grounding head body 210 relative to the connecting part 112.

[0094] It is worth noting that there are many ways to connect the fixing part 111 to the ground wire stake. The fixing part 111 and the ground wire stake can be connected by bolts, clamps, or other methods. These will not be listed here, as long as a detachable connection between the fixing part 111 and the ground wire stake is achieved. For some embodiments of the present invention, please refer to... Figure 1 , Figure 2 as well as Figure 5 The passive grounding stake lock 100 also includes a clamping member 400, which is detachably connected to the fixing part 111. The clamping member 400 and the fixing part 111 are used to clamp the grounding stake together.

[0095] There are various ways to connect the clamping member 400 and the fixing part 111. The clamping member 400 and the fixing part 111 can be connected by bolts and nuts. The clamping member 400 and the fixing part 111 can also be connected by clamps, bolts and nuts. The clamping member 400 and the fixing part 111 can also be detachably connected by other structural components, which will not be listed here.

[0096] Furthermore, the clamping member 400 has a recessed receiving groove 410 on the surface facing the fixing part 111. One wall of the receiving groove 410 extends to form a relief opening 420. The receiving groove 410 is used to receive one end of the grounding stake, and the relief opening 420 is used to allow the other end of the grounding stake to protrude. With this arrangement, the grounding stake can be hidden between the fixing part 111 and the clamping member 400, thus avoiding the grounding stake from being exposed to the outside, which would cause the grounding stake to be disturbed or damaged by other external factors.

[0097] It should be noted that for the grounding stake and the grounding head body 210 to achieve electrical connection, it is only necessary to ensure that the grounding stake and the grounding head body 210 are in contact. For some embodiments of the present invention, please refer to... Figure 2The fixing part 111 extends through the connecting part 112 to form a first clearance hole 1111. The grounding stake is provided with a stake hole communicating with the first clearance hole 1111, that is, the stake hole is located on the axial direction of the first clearance hole 1111. It is worth noting that if the grounding stake is fixed and clamped by the fixing part 111 and the clamping member 400, the clamping member 400 is also provided with a second clearance hole 430 communicating with the stake hole.

[0098] The intelligent grounding head 200 also includes a locking rod 240, which is electrically connected to the grounding head body 210, thus realizing the electrical connection between the locking rod 240 and the grounding wire. One end of the locking rod 240 is connected to the grounding head body 210, and the other end of the locking rod 240 extends along the extension direction of the connecting part 112. The end of the locking rod 240 away from the grounding head body 210 can pass through the first clearance hole 1111 and the pile hole. If the grounding pile is fixedly clamped by the fixing part 111 and the clamping member 400, the end of the locking rod 240 away from the grounding head body 210 can also pass through the second clearance hole 430.

[0099] During the process of locking the smart grounding head 200 to the support base 110, when the grounding head body 210 is located in the first position away from the second position, the locking rod 240 is spaced apart from the first clearance hole 1111 and the pile hole, and the first clearance hole 1111 is locked by the unlocking module 120. When the grounding head body 210 is in the first position, the locking rod 240 is still spaced apart from the first clearance hole 1111 and the pile hole, and the unlocking module 120 is in the unlocked state, that is, the first clearance hole 1111 is in the open state, and the locking rod 240 can pass through the first clearance hole 1111. When the grounding head body 210 is in the second position, the locking rod 240 passes through the first clearance hole 1111 and the pile hole, and the locking rod 240 is electrically connected to the grounding pile. The unlocking module 120 switches from the unlocked state to the locked state and applies a constraint to the locking rod 240, so that the locking rod 240 cannot move relative to the fixed part 111.

[0100] During the process of removing the smart grounding head 200 from the support base 110, when the grounding head body 210 is in the second position, the locking rod 240 cannot move relative to the fixed part 111 because it is constrained by the unlocking module 120. Therefore, it is necessary to first switch the unlocking module 120 from the locked state to the unlocked state. After the unlocking module 120 removes the constraint, the locking rod 240 can move relative to the fixed part 111. When the grounding head body 210 moves from the second position to the first position, the locking rod 240 exits from the pile hole and the first clearance hole 1111, which realizes the disconnection of the locking rod 240 from the grounding pile. At the same time, the unlocking module 120 switches to the locked state.

[0101] Furthermore, please refer to the following: Figure 6The passive grounding stake lock 100 also includes a conductive copper sleeve 500, which is installed in the first clearance hole 1111. The two can be connected by plugging, threading, etc. A plugging boss 510 is provided at one end of the conductive copper sleeve 500 adjacent to the stake hole. The plugging boss 510 can extend circumferentially along the conductive copper sleeve 500 in an arc or ring shape, and is used for plugging into the stake hole. With this configuration, as long as the locking rod 240 is inserted into the conductive copper sleeve 500, the locking rod 240 can move along the conductive copper sleeve 500 and plug into the stake hole on the grounding stake, thus ensuring the electrical connection between the locking rod 240 and the grounding stake.

[0102] Furthermore, since the conductive copper sleeve 500 itself has good conductivity, and the conductive copper sleeve 500 is also in contact with the grounding stake, that is, the conductive copper sleeve 500 is conductive to the grounding stake. When the conductive copper sleeve 500 is in contact with the locking rod 240, it can also achieve electrical connection between the locking rod 240 and the grounding stake. With this setting, when the conductive copper sleeve 500 is in contact with the locking rod 240, even if the locking rod 240 is not in direct contact with the grounding stake, the electrical connection between the locking rod 240 and the grounding stake can still be ensured.

[0103] Furthermore, the end of the conductive copper sleeve 500 away from the pile hole of the ground wire stake is turned outward to form a flange 520. When the conductive copper sleeve 500 is inserted into the first clearance hole 1111, the insertion boss 510 of one axial end of the conductive copper sleeve 500 is inserted into the pile hole on the ground wire stake, and the flange 520 of the other axial end of the conductive copper sleeve 500 abuts against the outer edge of the first clearance hole 1111. This arrangement facilitates the assembly of the conductive copper sleeve 500 onto the fixing part 111.

[0104] Furthermore, the inner diameter of the conductive copper sleeve 500 is smaller than the hole diameter of the grounding stake, and the inner diameter of the locking rod 240 is adapted to the inner diameter of the conductive copper sleeve 500. This arrangement ensures that the passive grounding stake lock 100 can only be used with a matching smart grounding head 200, thereby avoiding the problem of a smart grounding head 200 that is not compatible with the passive grounding stake lock 100 being connected in series with the passive grounding stake lock 100.

[0105] Based on the above embodiments, please refer to Figures 2 to 4The grounding device 1000 also includes a butterfly nut 600, which is used for threaded connection with the locking rod 240. When the intelligent grounding head 200 is locked onto the passive grounding stake lock 100, and the grounding head body 210 is in the second position, the end of the locking rod 240 away from the sliding seat passes through the first clearance hole 1111 and the stake hole. The butterfly nut 600 is then threadedly connected to the end of the locking rod 240 that passes through the first clearance hole 1111 and the stake hole. When the intelligent grounding head 200 needs to be removed from the passive grounding stake lock 100, the butterfly nut 600 needs to be removed from the locking rod 240 first. This design ensures that the intelligent grounding head 200 is not easily detached from the passive grounding stake lock 100 when it is locked onto it.

[0106] For a scheme where the fixing part 111 is provided with a first clearance hole 1111, and the first clearance hole 1111 communicates with the pile hole of the ground wire stake, please refer to [reference needed]. Figure 2 and Figure 7 The fixing part 111 is also provided with a mounting cavity 1112 and a first clearance hole 1113. The mounting cavity 1112 is located on the periphery of the first clearance hole 1111. The first clearance hole 1113 is used to connect the mounting cavity 1112 and the first clearance hole 1111. The unlocking module 120 is installed in the mounting cavity 1112. The unlocking module 120 can at least partially extend into the first clearance hole 1111 or retract from the first clearance hole 1111.

[0107] The outer peripheral wall of the locking rod 240 is provided with a locking part 241, which is used to cooperate with the unlocking and locking module 120. That is, when the unlocking and locking module 120 is in the locked state, the unlocking and locking module 120 extends at least partially into the first clearance hole 1111. At this time, the unlocking and locking module 120 cooperates with the locking part 241 on the locking rod 240, thereby constraining the locking rod 240 and restricting the movement of the locking rod 240 relative to the fixed part 111. When the unlocking and locking module 120 is in the unlocked state, the part of the unlocking and locking module 120 located in the first clearance hole 1111 exits from the first clearance hole 1111, thereby removing the constraint on the locking rod 240, which allows the locking rod 240 to move relative to the fixed part 111.

[0108] Please refer to the following: Figure 8 The locking / unlocking module 120 includes an electronic lock cylinder 121, an elastic reset member 122, a transmission shaft 123, and a locking pin 124. The locking pin 124 is elongated and has a locking end and a limiting end that are disposed opposite to each other. The locking pin 124 is movably installed in the mounting cavity 1112. The locking end of the locking pin 124 can extend from the first clearance hole 1113 into the first clearance hole 1111 or retract from the first clearance hole 1111.

[0109] The elastic reset member 122 can be a spring, a spring sheet, or other structural components that can generate elastic force. The elastic reset member 122 is installed in the mounting cavity 1112. The elastic reset member 122 acts on the locking pin 124 so that the locking end of the locking pin 124 always remains in the state of extending from the first clearance hole 1113 into the first clearance hole 1111.

[0110] The transmission shaft 123 is located on the side of the locking pin 124 away from the first clearance hole 1113. The transmission shaft 123 includes a connecting section 1231 and abutting section 1232. The extending direction of the connecting section 1231 is consistent with the axial direction of the locking pin 124. The connecting section 1231 is rotatably installed in the mounting cavity 1112. The abutting section 1232 is laterally protruding from the connecting section 1231. As the connecting section 1231 rotates, the abutting section 1232 has a locked position that abuts against the limiting end of the locking pin 124 and an unlocked position that is misaligned with the limiting end of the locking pin 124.

[0111] The electronic lock cylinder 121 is installed in the mounting cavity 1112. The electronic lock cylinder 121 is electrically connected to two wireless charging modules 130. The electronic lock cylinder 121 is also electrically connected to the control module, that is, the control module is used to control the electronic lock cylinder 121 to switch between locking and unlocking. The output end of the electronic lock cylinder 121 is connected to the connecting section 1231 of the transmission shaft 123. When the electronic lock cylinder 121 switches between locking and unlocking, it can drive the connecting section 1231 of the transmission shaft 123 to rotate.

[0112] Based on the above technical solution, when the electronic lock cylinder 121 is locked, the electronic lock cylinder 121 drives the connecting section 1231 of the transmission shaft 123 to rotate to the locked position. At this time, the abutting section 1232 of the transmission shaft 123 is aligned with the limiting end of the locking pin 124 and abuts against the limiting end of the locking pin 124, thereby restricting the locking end of the locking pin 124 from retracting from the first clearance hole 1111 into the first clearance hole 1113.

[0113] When the electronic lock cylinder 121 is unlocked, the electronic lock cylinder 121 drives the connecting section 1231 of the transmission shaft 123 to rotate to the unlock position. At this time, the abutting section 1232 of the transmission shaft 123 is misaligned with the limiting end of the locking pin 124, thereby releasing the constraint on the locking pin 124. At this time, the locking pin 124 can be retracted from the first clearance hole 1111 to the first clearance hole 1113 by the action of external force. That is to say, at this time, only a force along the axial direction of the locking rod 240 needs to be applied to the locking rod 240 to drive the locking rod 240 to move relative to the fixed part 111.

[0114] It is worth noting that please refer to the following as well. Figure 2 and Figure 6When the conductive copper sleeve 500 is installed in the first clearance hole 1111, the conductive copper sleeve 500 is provided with a third clearance hole 530. The third clearance hole 530 is aligned with the first clearance hole 1113 so that the locking end of the locking pin 124 can pass through the third clearance hole 530 and extend into the interior of the conductive copper sleeve 500, thereby cooperating with the locking part 241 on the locking rod 240 to lock or unlock the locking rod 240.

[0115] Furthermore, the elastic reset member 122 includes two sets of springs, and the limiting end of the locking pin 124 is provided with two positioning protrusions 1241. One end of each set of springs is sleeved with the corresponding positioning protrusion 1241, and the other end of each set of springs extends away from the limiting end of the locking pin 124. The other end of each set of springs abuts against the cavity wall of the mounting cavity 1112 facing the limiting end of the locking pin 124. This arrangement facilitates the assembly between the elastic reset member 122 and the locking pin 124.

[0116] It is worth noting that the arrangement of the two positioning protrusions 1241 can easily affect the cooperation between the abutting section 1232 of the transmission shaft 123 and the limiting end of the locking pin 124. Therefore, the limiting end of the locking pin 124 is also provided with a limiting protrusion 1242. The limiting protrusion 1242 is spaced apart from the two positioning protrusions 1241. That is, the limiting protrusion 1242 can be located between the two positioning protrusions 1241, or the limiting protrusion 1242 can be located on the same side of the two positioning protrusions 1241. No specific limitation is made here. When the transmission shaft 1233 is in the locked position, the abutting section 1232 abuts against the limiting protrusion 1242. When the transmission shaft 123 is in the unlocked position, the abutting section 1232 is misaligned with the limiting protrusion 1242.

[0117] Considering that the locking / unlocking module 120 has many components, in order to facilitate the quick assembly of the locking / unlocking module 120 onto the fixing part 111, in some embodiments of the present invention, please refer to... Figure 2 and Figure 9 The locking / unlocking module 120 also includes a locking cover 125 and a locking shell 126. Both the locking cover 125 and the locking shell 126 are installed in the mounting cavity 1112. The locking cover 125 and the locking shell 126 are connected and jointly define the assembly cavity. The locking cover 125 is provided with a first through hole 1251, and the locking shell 126 is provided with a second through hole 1261.

[0118] The locking pin 124 and the elastic reset member 122 are both installed in the assembly cavity. The locking end of the locking pin 124 can extend out from the first through hole 1251. One end of the connecting section 1231 of the transmission shaft 123 extends into the assembly cavity from the second through hole 1261. The other end of the connecting section 1231 of the transmission shaft 123 is located outside the assembly cavity and is connected to the output end of the electronic lock core 121. The abutting section 1232 of the transmission shaft 123 is located inside the assembly cavity.

[0119] Since the locking pin 124 and the elastic reset member 122 of the locking / unlocking module 120 are integrated into the locking housing 126 and the locking cover 125, the locking pin 124, the elastic reset member 122, the locking housing 126, and the locking cover 125 can be modularly configured. When assembling the locking / unlocking module 120 onto the support base 110, it is only necessary to assemble the electronic lock cylinder 121, the transmission shaft 123, and the modularly configured locking pin 124, elastic reset member 122, locking housing 126, and locking cover 125 onto the fixing part 111, which facilitates the assembly of the locking / unlocking module 120 and the fixing part 111.

[0120] Furthermore, the mounting cavity 1112 is also provided with a second clearance hole 1114. The locking and unlocking module 120 also includes a mechanical lock cylinder 127, which is installed in the mounting cavity 1112. The keyhole of the mechanical lock cylinder 127 is exposed from the second clearance hole 1114. The output end of the mechanical lock cylinder 127 is connected to the connecting section 1231 of the transmission shaft 123. When the mechanical lock cylinder 127 switches between locking and unlocking, it can drive the connecting section 1231 of the transmission shaft 123 to rotate.

[0121] This configuration allows the mechanical lock cylinder 127 to be used to unlock or lock the locking pin 124 whether the electronic lock cylinder 121 is working normally or malfunctioning. This increases the unlocking and locking methods for the locking pin 124, thereby preventing the problem of the locking pin 124 being unable to lock or unlock due to malfunction of the electronic lock cylinder 121.

[0122] Further, please refer to Figure 2 and Figure 7 The passive grounding stake lock 100 also includes a dust cover 700, which is connected to the fixing part 111. The dust cover 700 is also used to cover the second clearance hole 1114. This setting can effectively prevent dust, paper scraps and other small particles from entering the keyhole of the mechanical lock cylinder 127, thereby preventing the keyhole of the mechanical lock cylinder 127 from being blocked.

[0123] It should be noted that there are many ways to connect the dust cover 700 and the fixing part 111. For example, the dust cover 700 and the fixing part 111 can be connected by a snap fastener. Specifically, the dust cover 700 has hooks at both ends that are arranged opposite to each other, and the surface of the support base 110 is recessed with two buckle holes. The two buckle holes are located on the two opposite sides of the second clearance hole 1114, and the two buckle holes are engaged with the corresponding hooks.

[0124] For example, one end of the dust cover 700 is rotatably connected to the fixing part 111, and the other end of the dust cover 700 can rotate relative to the support base 110. When the dust cover 700 covers the support base 110, the dust cover 700 seals the second clearance hole 1114. After the dust cover 700 rotates a certain angle relative to the support base 110, the dust cover 700 opens the second clearance hole 1114, thereby facilitating the operator to unlock or lock the mechanical lock cylinder 127 with a key.

[0125] Furthermore, the passive grounding stake lock 100 also includes a sealing gasket 800 made of silicone material. The sealing gasket 800 is positioned between the dust cover 700 and the support base 110, sealing the gap between them. It also covers the second clearance hole 1114. This arrangement further ensures that fine particles such as dust, dirt, and paper scraps cannot enter the keyhole of the mechanical lock cylinder 127 through the second clearance hole 1114.

[0126] To facilitate identification of the ground wire head body 210 moving to the first or second position, in some embodiments of the present invention, please refer to... Figure 1 and Figure 9 The upper surface of the connecting part 112 is recessed with a sliding groove 1121. The sliding groove 1121 extends along the extending direction of the connecting part 112. The ground wire head body 210 is slidably connected to the sliding groove 1121 so that it can slide relative to the connecting part 112 along the extending direction of the sliding groove 1121.

[0127] Two tactile beads 1122 are provided on the wall of the sliding groove 1121. The distance between the two tactile beads 1122 in the extension direction of the connecting part 112 is equal to the distance between the two wireless charging modules 130 in the extension direction of the connecting part 112. The ground wire head body 210 has a positioning hole 211 recessed on its surface facing the two tactile beads 1122. When the positioning hole 211 is engaged with either of the two tactile beads 1122, the wireless power supply module 230 is aligned with the corresponding wireless charging module 130. This arrangement facilitates the determination of the position of the ground wire head body 210, thereby facilitating subsequent operations.

[0128] Obviously, in order to facilitate the identification of the ground wire head body 210 moving to the first position or the second position, other technical means can also be used. In some embodiments of the present invention, the ground wire device 1000 further includes two signal transmitting devices and a signal receiving device. Specifically, the two signal transmitting devices are disposed on the upper surface of the connecting part 112. The two signal transmitting devices are arranged at intervals along the extension direction of the connecting part 112. The distance between the two signal transmitting devices in the extension direction of the connecting part 112 is equal to the distance between the two wireless charging modules 130 in the extension direction of the connecting part 112.

[0129] The signal receiving device is mounted on the ground wire head 210 and is electrically connected to the main control module 220. After the signal receiving device is aligned with either of the two signal transmitting devices, it can receive the activation signal emitted by the corresponding signal transmitting device. After the signal receiving device receives the activation signal, the main control module 220 controls the wireless power supply module 230 to supply power to the corresponding wireless charging module 130. This configuration facilitates the main control module 220 in controlling the wireless power supply module 230 to supply power to the wireless charging module 130.

[0130] It should be noted that there are many types of signal transmitting devices, and correspondingly, many types of signal receiving devices. For example, if the signal transmitting device is an optical signal transmitting device, such as a laser transmitting device or an infrared light transmitting device, the corresponding signal receiving device is an optical signal receiving device. As another example, if the signal transmitting device is a magnetic signal transmitting device, such as a magnet or an electromagnet, the corresponding signal receiving device is a magnetic signal receiving device. Yet another example is a contact device, and the corresponding signal receiving device is a microswitch.

[0131] Based on the above embodiments, please refer to Figure 1 , Figure 2 as well as Figure 9 The wireless power supply module 230 is a power supply coil, and the wireless charging module 130 is a power receiving coil. When the power supply coil and the power receiving coil coincide, the power supply coil supplies power to the power receiving coil, thereby enabling the power receiving coil to supply power to the control module and the unlocking / locking module 120. When the power supply coil and the power receiving coil are completely misaligned, the power supply coil stops supplying power to the power receiving coil, and at this time the power receiving coil also stops supplying power to the control module and the unlocking / locking module 120.

[0132] Furthermore, the connecting part 112 includes a connecting body 1123 and a connecting cover 1124. The connecting body 1123 and the connecting cover 1124 are detachably connected. The connecting body 1123 and the connecting cover 1124 together form a receiving cavity. The surface of the connecting body 1123 is recessed with two mounting holes 1125 that communicate with the receiving cavity. One of the two mounting holes 1125 is located at a first position, and the other of the two mounting holes 1125 is located at a second position.

[0133] The connecting part 112 also includes a mounting box 1126, which is installed inside the receiving cavity. The mounting box 1126 has two mounting protrusions 1126a corresponding to the two mounting holes 1125. The two mounting protrusions 1126a are inserted into the two mounting holes 1125 in a one-to-one correspondence. Two wireless charging modules 130 are installed inside the mounting box 1126, with each wireless charging module 130 corresponding to one of the two mounting protrusions 1126a. This design allows the two wireless charging modules 130 to be hidden within the connecting body, thus preventing interference from external factors. Furthermore, the modular design of the two wireless charging modules 130 facilitates their replacement and maintenance.

[0134] Furthermore, the connecting part 112 also includes two sealing rings 1127. The two sealing rings 1127 are used to seal the gap between the corresponding mounting protrusion 1126a and the corresponding mounting hole 1125. This not only prevents dust, insects and other small objects from entering the receiving cavity, but also provides a waterproof effect, thus preventing external water from entering the receiving cavity and affecting the normal operation of the wireless charging module 130.

[0135] It is worth noting that the locking rod 240 is electrically connected to the grounding wire. The locking rod 240 can be directly connected to the grounding wire, or it can be connected to the grounding wire via a conductive element. For some embodiments of this invention, please refer to... Figure 10 The ground wire head body 210 is made of conductive metal. A wiring hole 212 is provided on the side of the ground wire head body 210 away from the locking rod 240. The wiring hole 212 is used to connect to the ground wire. This arrangement facilitates the electrical connection between the ground wire and the locking rod 240, while also preventing the ground wire from affecting the locking rod 240 passing through the pile hole on the ground wire stake.

[0136] It should be noted that if the main control module 220 does not receive a new control command within a certain period of time after the locking / unlocking module 120 locks the locking bar 240, the main control module 220 enters a sleep state. To facilitate activation of the main control module 220, please refer to [the relevant documentation] in some embodiments of the present invention. Figure 11 The intelligent grounding head 200 also includes an activation button 250, which is located on the grounding head body 210. The activation button 250 is electrically connected to the main control module 220. When the activation button 250 is pressed, the main control module 220 is activated. Thus, when the grounding device 1000 needs to be unlocked, the main control module 220 is activated first through the activation button 250, and then the main control module 220 sends a control command to the unlocking module 120.

[0137] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
