[0034] Example

[0035] Please refer to Figure 1-Figure 6 , Figure 1-Figure 6 An embodiment of the present application is shown.

[0036] This embodiment provides a grounding rod, such as Figures 1 to 4 As shown, it includes a wire clamp 1, a shell seat 301 is inserted into the side of the wire clamp 1, and the bottom of the shell seat 301 is embedded in the groove on the side of the wire clamp 1. A trigger block 302 is rotatably connected to the shell seat 301 through a rotating shaft 3021. The trigger block 302 is integrally connected with a pressing column 303, and the pressing column 303 abuts against a pressing plate of a pressing power generation module 304. For example, the pressing power generation module 304 uses the brand LISM and the model is PM4250. The pressing power generation module 304 is connected to the communication module 306 through a wire. The pressing power generation module 304 and the communication module 306 are both inserted into the shell seat 301 through a card slot integrally provided in the shell seat 301, and are fixed by hot melt adhesive.

[0037] When in use, when the cable enters the wire clamp 1, the trigger block 302 is squeezed to make it rotate. The rotation of the trigger block 302 drives the pressing column 303 to squeeze the pressing power generation module 304. The working principle of the pressing power generation module 304 is to use energy collection technology to convert the trace kinetic energy generated by the cable squeezing the trigger block 302 into electrical energy and supply it to the communication module 306 through the wire. After the communication module 306 is powered on, it collects information from other supporting data acquisition equipment (such as attitude sensors, pyroelectric infrared sensors, millimeter wave radar sensors, etc.) and then transmits it to the management background server through the APN wireless private network to complete the process monitoring of power outage maintenance.

[0038] It should be noted that the communication module 306 is set according to the Q / GDW 12242-2022 technical standard, and no separate description or specific limitation is given here; the press-to-power generation module 304 is mainly used to generate micro-kinetic energy generated by the trigger block 302 when the wire clamp 1 changes from a hooked state to a non-hooked state, and does not involve the power supply of other data acquisition equipment.

[0039] Through the above technical solution, the press power generation module 304 is used to provide a long-life, maintenance-free power supply for the communication module 306 of the ground rod, thereby improving the convenience of carrying and using for workers.

[0040] As a preferred implementation method, Figure 1 and Figure 4 As shown, the shell seat 301 abuts against the outside of the wire clamp 1, and the opening of the shell seat 301 abuts against the shell cover 305, which is integrally provided with two connecting columns 3051, and the connecting columns 3051 are connected to the threaded holes 101 drilled on the side wall of the wire clamp 1 by screws.

[0041] When in use, first connect the press-to-generate power module 304 and the communication module 306 through a wire, insert them into the shell base 301, then insert the connecting column 3051 into the two through holes of the shell base 301, and finally use two screws to pass through the connecting column 3051 to install the shell cover 305 and the shell base 301 together on the side wall of the wire clamp 1.

[0042] Through the above technical solution, the shell cover 305 is pressed against the shell base 301 and directly connected to the side wall of the wire clamp 1, which reduces the number of connection holes and avoids reducing the rigidity of the side wall of the wire clamp 1. At the same time, the shell cover 305 can protect the internal components of the shell base 301.

[0043] As a preferred implementation method, Figure 3 and Figure 4 As shown, the wire clamp 1 is riveted with a plug-in tube 1 401 , the plug-in tube 1 401 is detachably connected with a plug-in tube 2 410 , and the plug-in tube 2 410 is riveted with an insulating rod 2 .

[0044] Through the above technical solution, a combination of two plug-in barrels is adopted to realize the detachability of the wire clamp 1 and the insulating rod 2, thereby improving the convenience of outdoor carrying and the interchangeability after damage.

[0045] As a preferred implementation method, Figure 3 and Figure 6As shown, the outer side of the plug-in tube 410 is slidably sleeved with a clamping tube 406, and the side wall of the plug-in tube 410 is provided with four evenly distributed grooves, and a steel ball 408 is movably connected in each groove, and the diameter of one end of the groove is larger than the diameter of the steel ball 408 and the diameter of the other end is smaller than the diameter of the steel ball 408. The plug-in tube 401 is provided with an annular limiting groove 402, and the clamping tube 406 moves up and its side wall pushes the steel ball 408 to slide from the large opening end of the groove to the small opening end and abuts against the limiting groove 402, and the clamping tube 406 moves down and its side wall is separated from the steel ball 408, and the steel ball 408 exits the limiting groove 402. Figure 3 As shown, the inner side of the clamping tube 406 is divided into four layers, and the upper three layers are stepped with decreasing diameters from top to bottom, wherein the first layer allows the steel ball 408 to exit, and the second layer pushes the steel ball 408 in.

[0046] Through the above technical solution, the connection and separation of the plug-in tube are realized by the displacement of the steel ball 408 relative to the limiting groove 402, which makes the structure simpler and the operation more convenient.

[0047] As a preferred implementation method, Figure 3 and Figure 6 As shown, a spring 407 is installed between the fourth layer on the inner side of the above-mentioned clamping cylinder 406 and the second plug-in cylinder 410, one end of the spring 407 abuts against the bottom surface of the third layer on the inner side of the clamping cylinder 406 and the other end abuts against the step of the second plug-in cylinder 410. The spring 407 pushes the clamping cylinder 406 to move away along the axial direction of the second plug-in cylinder 410, and the top end of the second plug-in cylinder 410 is clamped with an open elastic clamping ring 405, and the diameter of the clamping ring 405 is larger than the diameter of the second layer on the inner side of the clamping cylinder 406 to form a limit for the clamping cylinder 406.

[0048] When in use, the spring 407 is inserted into the second plug-in tube 410 , and then into the clamping tube 406 , the clamping tube 406 is pressed down to reveal the groove, and four steel balls 408 are placed in the groove, and then the clamping ring 405 is clamped into the top of the second plug-in tube 410 .

[0049] Through the above technical solution, the clamping ring 405 is used to limit the clamping tube 406, which makes it easy to disassemble the clamping tube 406 and replace the steel ball 408, making maintenance more convenient.

[0050] As a preferred implementation method, Figure 3 As shown, the second plug-in tube 410 is plugged with a plug pin 409 , and the plug pin 409 abuts against the first plug-in tube 401 .

[0051] Through the above technical solution, the insertion depth of the plug-in tube 401 is limited by the latch 409, which makes the operation more convenient.

[0052] As a preferred implementation method, Figure 3 and Figure 6As shown, the above-mentioned plug-in tube 1 401 is connected to an anti-rotation head 403, and the anti-rotation head 403 and the latch pin 409 abut against each other.

[0053] Through the above technical solution, the latch 409 and the anti-rotation head 403 are used to stabilize the relative angle between the first plug-in tube 401 and the second plug-in tube 410, thereby improving the stability of the wire clamp 1 during connection.

[0054] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
