[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present invention.

The orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "top", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0025] As Figures 1 to 4 shown, an intelligent grounding wire device includes a rod body 1, a hook 2 is provided at the end of the rod body 1, a positioning device 3 is detachably installed on the rod body 1, an insertion leg 4 is provided on the positioning device 3, and a clamping mechanism for clamping the insertion leg 4 is provided inside the rod body 1. The clamping mechanism includes an extrusion block 5 slidably connected to the rod body 1 and two pressing blocks 6 with adjustable relative distance. Adjusting the extrusion block 5 drives the pressing blocks 6 to clamp or release the insertion leg 4.

[0026] By providing the insertion leg 4 inserted inside the rod body 1 and cooperating with the clamping mechanism, the detachable connection of the positioning device 3 is realized. The clamping and fixing are convenient for disassembling and installing the positioning device 3, thus facilitating maintenance and improving the inspection efficiency. The clamping mechanism is arranged inside the rod body 1 to avoid damage caused by collision of the clamping mechanism or foreign objects entering and affecting the normal use of the positioning device 3. The extrusion block 5 and the pressing blocks 6 are linked, which is convenient for operating and controlling the state of the clamping mechanism from the outside of the rod body 1, improving the practicability.

[0027] In the intelligent grounding wire device of this embodiment, the insertion leg 4 is arranged perpendicular to the rod body 1, and pressing blocks 6 are respectively arranged on the upper and lower sides of the insertion leg 4. The pressing blocks 6 are slidably connected in the sliding cavity.

[0028] Specifically, a plug-in groove matching the plug-in leg 4 is provided in the rod body 1. The plug-in groove communicates with the sliding cavity. The pressing blocks 6 on the upper and lower sides slide in the sliding cavity and approach each other to press and fix the plug-in leg 4, realizing the installation of the positioning device 3 on the rod body 1; when the pressing blocks 6 move away from each other, the plug-in leg 4 is released, facilitating the sliding of the plug-in leg 4 in the plug-in groove for disassembly.

[0029] Preferably, there are two plug-in legs 4, and correspondingly, there are two extrusion blocks 5. Only when the two plug-in legs 4 are simultaneously released by the pressing blocks 6 can the positioning device 3 be disassembled, improving the installation stability of the positioning device 3 and preventing the plug-in leg 4 from detaching from the rod body 1 due to the movement of the extrusion block 5 caused by accidental collision.

[0030] Preferably, the extrusion block 5 is flush with the surface of the rod body 1 to avoid being easily damaged by collision due to protrusion. At the same time, the two extrusion blocks 5 are oppositely arranged on the rod body 1, facilitating the simultaneous pressing of the extrusion blocks 5 into the rod body to improve the operation convenience.

[0031] Preferably, a rubber layer is provided on the surface of the pressing block 6 in contact with the plug-in leg 4 to increase the friction between the pressing block 6 and the plug-in leg 4, thereby ensuring the installation and fixing effect of the positioning device 3.

[0032] In the intelligent grounding wire device of this embodiment, the pressing block 6 slides along the extension direction of the rod body 1. A spring 7 is connected between the two pressing blocks 6, and the spring 7 pulls the two pressing blocks 6 to clamp and limit the plug-in leg 4.

[0033] Specifically, the spring 7 is a compression spring. The length of the spring 7 in its initial state is less than the height of the plug-in leg 4, thereby tightening the pressing blocks 6 on the upper and lower sides to press and fix the plug-in leg 4.

[0034] In the intelligent grounding wire device of this embodiment, there are two springs 7. The two springs 7 are respectively arranged on both sides of the plug-in leg 4 and are symmetrically arranged with respect to the plug-in leg 4.

[0035] Preferably, the springs 7 are symmetrically arranged with respect to the plug-in leg 4 to ensure uniform force on the pressing block 6 and simultaneously stably press the plug-in leg 4, improving the installation stability of the positioning device 3.

[0036] In the intelligent grounding wire device of this embodiment, a first inclined surface is provided on the side of the pressing block 6 close to the surface of the rod body 1. The first inclined surfaces on the two pressing blocks 6 are oppositely arranged, and a pushing block 8 is arranged between the two first inclined surfaces.

[0037] By setting the opposite first inclined surfaces and the pushing block 8, the movement of the pushing block 8 is used to push the pressing blocks 6 away from each other, thereby stretching the spring 7 and removing the pressing force on the plug-in leg 4 for disassembling the positioning device 3, facilitating maintenance and replacement.

[0038] In the intelligent grounding wire device of this embodiment, the upper and lower ends of the pushing block 8 are provided with second inclined surfaces, the angles of the second inclined surfaces are the same as those of the first inclined surfaces, and the second inclined surfaces and the first inclined surfaces are arranged to be relatively slidable.

[0039] Specifically, as Figure 4 , the longitudinal section of the pushing block 8 is trapezoidal. Moving the pushing block 8 horizontally, the two pressing blocks 6 are pushed away from each other through the cooperation of the second inclined surface and the first inclined surface, so as to release the fixation of the insertion leg 4; when the force on the pushing block 8 disappears, the spring 7 contracts to pull the two pressing blocks 6 closer, and at this time, the first inclined surface drives the pushing block 8 to reset through the second inclined surface.

[0040] In the intelligent grounding wire device of this embodiment, the pushing block 8 is slidably connected in the pushing cavity, the pushing cavity is perpendicular to the sliding cavity and communicates with the sliding cavity, and the pushing block 8 is fixedly connected to the extrusion block 5.

[0041] Through the above settings, pressing the extrusion block 5 on the surface of the rod body 1 can drive the pushing block 8 to move, realizing linkage.

[0042] In the intelligent grounding wire device of this embodiment, limiting blocks are respectively fixedly connected to the upper and lower sides of the extrusion block 5, the limiting blocks are slidably connected in the limiting grooves 9, and the outer surface of the extrusion block 5 matches the surface of the rod body 1.

[0043] The cooperation of the limiting blocks and the limiting grooves 9 is set to guide the sliding of the extrusion block 5, and at the same time, to prevent the extrusion block 5 from being pushed out of the pushing cavity by the pressing block 6 when the spring 7 contracts, ensuring that the first inclined surface and the second inclined surface remain in contact.

[0044] In the intelligent grounding wire device of this embodiment, the side of the positioning device 3 close to the rod body 1 fits the surface of the rod body 1, and a GPS positioning module, a GPRS communication module, a wireless transmission module and a central processor are installed in the positioning device 4.

[0045] Through the above structure, with the cooperation of the circuit board, through the capabilities of the GPS positioning module, the GPRS communication module, the wireless transmission module and the central processor, it can have GPS or Beidou positioning functions, can be remotely accessed on the web interface to query the longitude and latitude information of the grounding wire and the working status information, and at the same time, supports the GPRS communication mode and can communicate remotely, thus achieving the purpose of high intelligence.

[0046] In the intelligent grounding wire device of this embodiment, the positioning device 4 and the hook 2 are located on the same side of the rod body 1, a double-tongue grounding wire head 10 is arranged between the hook 2 and the rod body 1, and a wiring terminal is installed on the rod body 1.

[0047] Through the above structure, the positioning device 4 is located inside the rod body 1, reducing the possibility of being collided. A double-tongue grounding wire head 10 is fixedly connected to the end of the rod body 1, and a grounding wire connection terminal is arranged at the left end of the bottom of the double-tongue grounding wire head 10.

For example, it can be a fixed connection, a detachable connection, or integrated; 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 communication of two components or the interaction relationship between two components. Unless otherwise clearly defined, for those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0049] Although the embodiments of the present utility model have been shown and described in detail, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
