Obviously, the described embodiments are some but not all of the embodiments of the present utility model.

[0031] As Figures 1-7As shown in the figure, this embodiment proposes a grounding device for an electrical equipment distribution cabinet, including a distribution cabinet 1, a ground wire 2, and a grounding rod 4. One end of the ground wire 2 is connected to the distribution cabinet 1. The top of the grounding rod 4 is threadedly connected with a wiring component 9 that cooperates with the ground wire 2. A protection component is provided outside the wiring component 9. The protection component includes a first protection shell 5 and a second protection shell 6 that are detachably connected by bolts. A plurality of sealing sleeves 3 that communicate with the inside of the first protection shell 5 are installed on the first protection shell 5. An adjustable clamp 10 is installed outside the sealing sleeve 3. By setting the sealing sleeve 3 and the adjustable clamp 10, during use, by adjusting the adjustable clamp 10, one end of the sealing sleeve 3 can be contracted to closely adhere to the surface of the ground wire 2, preventing water from entering the inside of the protection component through the gap between the ground wire 2 and the wiring hole, and facilitating the use with ground wires 2 of different diameters; an inspection opening is provided on the second protection shell 6. A sealing cover 7 for closing the inspection opening is detachably installed on the outer wall of the second protection shell 6. An observation window 8 is inlaid at the center of the sealing cover 7. By setting the sealing cover 7, the observation window 8, and the inspection opening, when maintenance or installation of the ground wire 2 is required, only the screws at the four corners of the sealing cover 7 need to be unscrewed to remove the sealing cover 7. At this time, through the inspection opening, maintenance of the wiring component 9 inside the protection component or installation and disassembly operations of the ground wire 2 can be carried out without disassembling the entire protection component. At the same time, during daily use, through the transparent observation window 8, it is also possible to directly check whether the wiring component 9 or the ground wire 2 connected to it is corroded; a first installation groove 17 is provided at the center of the top of the grounding rod 4. A connecting block 19 is slidably installed inside the first installation groove 17. Two first connecting rods 15 that are rotatably connected to the outer wall of the connecting block 19 are symmetrically installed on the outer wall of the connecting block 19. One end of the first connecting rod 15 away from the connecting block 19 is hinged to a second connecting rod 16. One end of the second connecting rod 16 away from the first connecting rod 15 is rotatably connected to the grounding rod 4. A second installation groove 18 that cooperates with the first connecting rod 15 and the second connecting rod 16 is provided on the grounding rod 4. A top rod 20 that cooperates with the connecting block 19 is movably installed inside the first installation groove 17. Through the setting of the first connecting rod 15, the second connecting rod 16, the connecting block 19, and the top rod 20, after the grounding rod 4 is inserted into the soil layer, the top rod 20 is inserted into the first installation groove 17, and then the top rod 20 is hammered to drive the connecting block 19 to descend. During the descent of the connecting block 19, the first connecting rod 15 and the second connecting rod 16 that are retracted inside the second installation groove 18 will open, and both will be inserted into the soil, thereby improving the overall grip of the grounding rod 4 and avoiding the problem of loosening of the grounding rod 4 during use.

[0032] As Figure 4As shown, as a preferred embodiment, on the basis of the above method, further, an installation hole 11 that cooperates with the grounding rod 4 is provided at the bottom of the protection component, and a washer 12 is installed inside the installation hole 11. It should be noted that through the setting of the installation hole 11, the top of the grounding rod 4 can be conveniently inserted into the interior of the protection component, and through the setting of the washer 12, the gap between the grounding rod 4 and the installation hole 11 can be sealed.

[0033] As Figure 3 and Figure 4 shown, as a preferred embodiment, on the basis of the above method, further, a plurality of wiring holes that cooperate with the sealing sleeve 3 are provided on the first protective shell 5, and a plug 14 is threadedly connected to the inside of the wiring holes. It should be noted that through the setting of the plug 14, the unused wiring holes can be closed during use to prevent water from entering the wiring holes.

It should be noted that through the setting of the annular groove 13, the installation of the adjustable clamp 10 can be facilitated.

[0035] As Figure 1 , Figure 2 and Figure 6 shown, as a preferred embodiment, on the basis of the above method, further, the adjustable clamp 10 includes a first clamping plate 101 and a second clamping plate 102 that are symmetrically arranged, and the first clamping plate 101 and the second clamping plate 102 are movably connected by two oppositely arranged first adjusting screws 103. It should be noted that during use, by rotating the first adjusting screw 103, the distance between the first clamping plate 101 and the second clamping plate 102 can be adjusted, so that it can adapt to the use of ground wires 2 with different diameters.

[0036] As Figure 3 and Figure 5 shown, as a preferred embodiment, on the basis of the above method, further, the wiring component 9 includes a bottom plate 901 fixedly connected to the top of the grounding rod 4. A plurality of uniformly distributed grooves 903 are provided on the top of the bottom plate 901, and a wiring post 902 installed on the bottom plate 901 is provided inside the grooves 903.

A plurality of second adjusting screws 905 are threadedly connected to the frame 904. The bottom end of the second adjusting screw 905 is rotatably installed with a pressing block 906 located above the groove 903. The bottom of the pressing block 906 is provided with an arc-shaped depression. It should be noted that when in use, rotating the second adjusting screw 905 can drive the pressing block 906 to descend, so as to press the part of the ground wire 2 inside the groove 903 through the pressing block 906, thereby being able to fix the ground wire 2 again and prevent the ground wire 2 from falling off the terminal 902 when being pulled.

[0038] As Figures 1-4 shown, as a preferred embodiment, on the basis of the above method, further, a gasket is provided inside the sealing cover 7, and screws for connecting the second protective shell 6 are provided at the four corners of the sealing cover 7. It should be noted that through the setting of the gasket, the sealing performance between the sealing cover 7 and the second protective shell 6 can be improved, and through the setting of the screws, the installation and disassembly of the sealing cover 7 can be facilitated.

[0039] Specifically, the working principle of the grounding device of the electrical equipment distribution cabinet is as follows: Before use, insert the grounding rod 4 into the ground, insert the ejector rod 20 into the inside of the first installation groove 17, and then hammer the ejector rod 20 to drive the connecting block 19 to descend. During the descent of the connecting block 19, the first connecting rod 15 and the second connecting rod 16 retracted inside the second installation groove 18 will be driven to open, so that both are inserted into the soil, thereby improving the overall grip of the grounding rod 4. Then, install the wiring assembly 9 on the top of the grounding rod 4. When connecting the ground wire 2, first insert one end of the ground wire 2 into the inside of the protection assembly through the sealing sleeve 3 and the wire passing hole, and then connect one end of it to the wiring assembly 9. After connection, adjust the adjustable clamp 10 to contract one end of the sealing sleeve 3 so that it closely adheres to the surface of the ground wire 2 to prevent water from entering the inside of the protection assembly through the gap between the ground wire 2 and the wiring hole. When maintenance or installation of the ground wire 2 is required, just unscrew the screws at the four corners of the sealing cover 7 to remove the sealing cover 7. At this time, the wiring assembly 9 inside the protection assembly can be maintained or the installation and disassembly operation of the ground wire 2 can be carried out through the inspection port.
