[0002] Electricity is an energy source that uses electrical energy as its power source. The discovery and application of electricity sparked the second wave of industrialization. The power system is one of the most important achievements in the history of human engineering science. It is an electricity production and consumption system composed of power generation, transmission, transformation, distribution and consumption. It converts primary energy from nature into electricity through mechanical energy devices, and then supplies the electricity to users through transmission, transformation and distribution. At present, grounding devices are required in power construction. However, the existing grounding devices are too long and cannot be disassembled and carried, which is not conducive to people's use.

[0019] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.

[0020] Example:

[0021] like Figure 1 and Figure 2As shown, this embodiment provides a portable grounding device for power construction, including an insulating rod 1, a threaded rod 2, a mounting box 3, and a mounting box 3 detachably connected to the upper end of the mounting box 3. A grounding wire 5 is fixedly connected to one side of a connecting frame 4. The connection method between the connecting frame 4 and the mounting box 3 can remain unchanged, facilitating quick assembly and disassembly of the connecting frame 4 and solving the problem of the inconvenience of carrying the power construction grounding device. In addition, a connector 6 is fixed to the lower end of the mounting box 3. The threaded rod 2 is threaded vertically into the insulating rod 1, and the upper part of the threaded rod 2 penetrates the top surface of the insulating rod 1 and is detachably connected to the connector 6, facilitating the assembly and disassembly of the mounting box 3 and thus improving flexibility. An installation groove is opened in the middle of the insulating rod 1, and a handwheel 7 is rotatably installed in the installation groove. The middle of the handwheel 7 is provided with a threaded hole that is threadedly connected to the middle of the threaded rod 2. By rotating the handwheel 7, the threaded rod 2 can be raised or lowered relative to the insulating rod 1, thereby adjusting the height of the grounding wire 5.

[0022] This utility model allows for detachable connection between the connector 6 at the lower end of the mounting box 3 and the threaded rod 2, facilitating the loading and unloading of the mounting box 3 and thus improving flexibility. By rotating the handwheel 7 into the mounting groove, the height of the handwheel 7 remains constant. When the handwheel 7 is rotated, the threaded rod 2 can be raised or lowered, ultimately adjusting the height of the grounding wire 5, making adjustment simpler.

[0023] As a preferred embodiment of this invention, it should be further explained that the insulating rod 1 includes an insulating rod body 101 and an inverted U-shaped bracket 102 fixed to the upper end of the insulating rod body 101. Arc-shaped limiting grooves 1021 are provided on the inner walls of both sides of the inverted U-shaped bracket 102. The two arc-shaped limiting grooves 1021 are coaxially arranged and cooperate to form the mounting groove. The handwheel 7 is installed inside the inverted U-shaped bracket 102, and both ends of the handwheel 7 slide within the two arc-shaped limiting grooves 1021. The two arc-shaped limiting grooves 1021 limit the handwheel 7, allowing it to rotate but not move up or down. The threaded rod 2 is threadedly connected to the insulating rod body 101 and / or the inverted U-shaped bracket 102, thereby ensuring stable control of the threaded rod 2's spiral movement when the handwheel 7 is rotated.

[0024] As a preferred embodiment of this invention, it should be further explained that the handwheel 7 includes a central connecting ring 701 and multiple operating levers 702. The central connecting ring 701 is threaded to the outside of the threaded rod 2, realizing the threaded connection between the handwheel 7 and the threaded rod 2. All the operating levers 702 are evenly distributed on the outer wall of the central connecting ring 701. The end of the operating lever 702 away from the central connecting ring 701 is a spherical head structure that matches the arc-shaped limiting groove 1021. At least one operating lever 702 is slidably arranged in each arc-shaped limiting groove 1021. When the handwheel 7 is rotated, at least one end of the operating lever 702 will always be located in the arc-shaped limiting groove 1021 to ensure that the arc-shaped limiting groove 1021 always limits the handwheel 7.

[0025] As a preferred embodiment of this invention, it should be further noted that the distance between the inner top surface of the inverted U-shaped bracket 102 and the upper end of the insulating rod body 101 is S1, and the height of the middle connecting ring 701 is S2, where S1 > S2; the arc-shaped limiting groove 1021 is located in the middle of both sides of the inverted U-shaped bracket 102, making the rotation of the handwheel 7 easier.

[0026] As a preferred embodiment of this invention, it should be further noted that there are 6-8 operating levers 702. While ensuring convenient adjustment, it is sufficient to ensure that at least one end of the operating lever 702 is always located within the arc-shaped limiting groove 1021. The number of operating levers 702 is not specifically limited.

[0027] As a preferred embodiment of this invention, it should be further explained that the connecting piece 6 is a connecting nut, and the upper end of the threaded rod 2 is threadedly connected to the connecting piece 6. Therefore, in practice, when the threaded rod 2 rises, the mounting box 3, connecting frame 4, and grounding wire 5 can be driven to rise with the help of the connecting piece 6. When it is necessary to disassemble the mounting box 3, it is only necessary to control the connecting piece 6 to not rotate, and simultaneously rotate the handwheel 7 to disengage the threaded rod 2 from the connecting piece 6. It should be noted that in practice, an operator can use a wrench or other tools to limit the connecting piece 6 to prevent it from rotating. If possible, when the lower end of the connecting piece 6 contacts the top surface of the inverted U-shaped bracket 102, the friction between the connecting piece 6 and the inverted U-shaped bracket 102 can be used to prevent the connecting piece 6 from rotating. In this case, both contact surfaces can be rough surfaces to increase friction, ensuring that the threaded rod 2 can rotate even when the connecting piece 6 is not rotating, thus making the disassembly of the connecting piece 6 more convenient.

[0028] As a preferred embodiment of this invention, it should be further explained that the connector 6 is a sleeve, the upper end of the threaded rod 2 is inserted into the connector 6, and the connector 6 and the upper end of the threaded rod 2 are detachably connected by a pin. The installation and removal method is simple and convenient. In the actual installation and removal process, the upper end of the threaded rod 2 only needs to pass through the top surface of the entire insulating rod 1 to realize the quick installation and removal of the pin, and then realize the connection and disconnection of the connector 6 at the upper end of the threaded rod 2.

[0029] As a preferred embodiment of this invention, it should be further noted that positioning plates 8 are fixed on both sides of the bottom of the insulating rod 1, and mounting holes 801 are opened in the middle of the two positioning plates 8 to facilitate the installation of the insulating rod 1. Of course, the positioning plates 8 are also made of insulating material, just like in the prior art.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
