[0025] In the embodiment of the present invention, in the initial state, the extension plate 105 is retracted in the extension plate 104, the extension plate 104 is in the installation slot 102, the grounding electrode cylinder 101 is inserted into the ground, the connecting component 5 makes the extension plate 104 and the extension plate 2 105 fixedly connected, the flipping mechanism 2 drives the extension plate 2 105 to rotate upward, and the extension plate 2 105 drives the extension plate 104 to rotate upward synchronously, thereby increasing the contact range between the grounding electrode cylinder 101 and the soil, the connecting component 5 releases the fixed connection between the extension plate 104 and the extension plate 2 105 by rotating the extension plate 104 relative to the fixed shaft 103, the flipping mechanism 2 drives the extension plate 2 105 to slide out of the extension plate 104, thereby increasing the length of the extension plate 104, thereby further increasing the contact range between the grounding electrode cylinder 101 and the soil, thereby improving the surface pressure equalization effect of the grounding electrode cylinder 101.

[0026] like Figure 1-Figure 4As shown, as a preferred embodiment of the present invention, the flip mechanism 2 includes two sliding sleeves 202 slidably connected in the grounding electrode cylinder 101, a threaded sleeve 201 is arranged between the two sliding sleeves 202, the two ends of the threaded sleeve 201 are respectively fixedly connected to the two sliding sleeves 202, and the side walls of the sliding sleeves 202 are provided with guide ribs 203. The inner wall of the grounding electrode cylinder 101 is provided with a guide groove 204 slidingly matched with the guide ribs 203 along the length direction. A connecting rod 205 is rotatably connected to the side wall of the threaded sleeve 201, and the end of the connecting rod 205 is rotatably connected to a connecting seat 206.

The shielding plate 301 seals the guide groove 106 to prevent soil from entering the guide groove 106 and hindering the extension plate 2 105 from sliding into the extension plate 1 104.

[0030] like Figure 1-Figure 6 As shown, as a preferred embodiment of the present invention, the connecting component 5 includes a connecting lock groove 501 provided on the extension plate 105, and a slide groove 502, a wire hole 506 and a winding groove 508 provided on the extension plate 104, a slider 503 is slidably connected in the slide groove 502, a locking block 504 is fixed at one end of the slider 503, and a spring 505 is connected to the other end of the slider 503, the spring 505 is provided in the slide groove 502, the spring 505 pushes the slider 503 to move, and the slider 503 drives the locking block 504 to move toward the extension plate 105, a rope 507 is provided in the wire hole 506, one end of the rope 507 is connected to one end of the slider 503 close to the spring 505, and the other end of the rope 507 is connected to the fixed shaft 103, the winding groove 508 is located in the middle of the fixed shaft 103, and the other end of the rope 507 is located in the winding groove 508.

The slider 503 drives the locking block 504 to insert into the connecting lock slot 501, so that the first extension plate 104 is fixedly connected with the second extension plate 105. A tool such as a wrench is used to connect with the regular hexagonal protrusion 403. The regular hexagonal protrusion 403 is rotated by the tool. The regular hexagonal protrusion 403 drives the screw rod 401 to rotate. When the screw rod 401 drives the threaded sleeve 201 to move downward by thread transmission with the threaded sleeve 201, the threaded sleeve 201 pushes the second extension plate 104 through the connecting rod 205. 05 and extension plate 104 flip upward, thereby increasing the contact range between the grounding electrode cylinder 101 and the soil. As the extension plate 104 rotates, the extension plate 104 rotates relative to the fixed shaft 103, and the fixed shaft 103 reels the rope 507, so that the rope 507 gradually overcomes the elastic force of the spring 505 and pulls the slider 503 away from the extension plate 2 105, until the slider 503 drives the locking block 504 to disengage from the slide groove 502, and the extension plate 104 and the extension plate 2 105 are in a sliding connection state, and the connecting rod 205 pushes the extension plate 2 105 out of the extension plate 104, thereby increasing the length of the extension plate 104, thereby further increasing the contact range between the grounding electrode cylinder 101 and the soil, thereby improving the surface pressure equalization effect of the grounding electrode cylinder 101.
