Electric grounding pile for electric power engineering

[0022] The technical solution of the present invention will be further specifically described below in conjunction with the drawings.

[0023] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, a power grounding pile for power engineering includes a grounding pile body 1, a cavity 2, a plugging head 3, a push rod 4, an accommodation groove 5, a rotating shaft 6, a gear 7, a groove 8, a spring 9, and a limiter. Bit plate 10, rack plate 11 and elastic plate 12.

[0024] Wherein, the bottom of the grounding pile body 1 can be set to have an inverted conical structure, and the grounding pile body 1 is provided with a cylindrical cavity 2 passing through its height direction. The cavity 2 can also be set from top to bottom. The stepped cylindrical structure with the lower diameter sequentially reduced is convenient for limiting the position. The plugging head 3 is provided on the top of the grounding pile body 1, and the plugging head 3 is provided with a wiring hole 13 penetrating through its thickness direction. The cavity 2 is provided with a push rod 4, the upper part of the push rod 4 is fixedly connected with a wiring tube 15, the top of the push rod 4 is provided with a moving plate 14, and the moving plate 14 is provided with a wiring hole 13, And the wiring hole 13 communicates with the wiring hole 13 on the plug 3, and the two wiring holes 13 are arranged coaxially. The movable plate 14 is slidably arranged in the cavity 2, and the movable plate 14 is A sliding block is provided on the side surface where the inner side wall of the cavity 2 is in contact, and a sliding groove is arranged on the side wall of the cavity 2, and the movable plate 14 and the cavity 2 are slidably connected up and down through the sliding block and the sliding groove. The moving plate 14 is arranged in the upper half of the stepped cylindrical cavity 2. The steps inside the cavity 2 can limit the up and down movement of the moving plate 14. The lower part of the inner side wall of the cavity 2 is provided with The opening faces the accommodating groove 5 inside the cavity 2. A rotating shaft 6 is fixedly arranged in the accommodating groove 5, the rotating shaft 6 is rotatably connected with the gear 7, and the meshing teeth of the gear 7 face the cavity 2 , The push rod 4 is fixedly provided with a rack plate 11 meshingly connected with the gear 7, and the top of the containing groove 5 is provided with a groove 8 with an open bottom end, and the groove 8 is close to the side of the cavity 2 A transversely arranged spring 9 is fixedly connected to the wall, the other end of the spring 9 is fixedly connected to the limiting plate 10, and the other side of the limiting plate 10 is closely connected to the side wall of the groove 8 away from the cavity 2, and The bottom end of the limiting plate 10 extends between two adjacent meshing teeth, the top wall of the groove 8 is provided with a sliding groove, the top of the limiting plate 10 is provided with a slider, and the limiting plate 10 and the top wall of the groove 8 are slidably connected to the left and right through a sliding groove and a sliding block. The bottom end of the push rod 4 is hinged with the elastic plate 12, and the elastic plate 12 can be set in two, which are respectively hinged on the push rod. Both sides of the bottom end of the rod 4 are distributed in a roughly figure eight shape. A spring 9 can be fixed between the two elastic plates 12, and the bottom end of the elastic plate 12 can be a cone-shaped structure for easy penetration. In the soil.

[0025] In the specific implementation of the present invention, when the plugging head 3 is provided at the top of the grounding pile body 1, the push rod 4 and the grounding pile body 1 are driven down synchronously by external force. After the grounding pile body 1 penetrates the ground, the plugging is removed The head 3 strikes the push rod 4 again with an external force, so that the push rod 4 moves downward, the rack plate 11 on the push rod 4 meshes with the gear 7, and the gear 7 rotates in the positive direction, ie image 3 As shown in the figure, the meshing teeth on the gear 7 positively push the limit plate 10, and the limit plate 10 moves in the direction of the cavity in the groove 8, compressing the spring 9 until the current meshing tooth is out of the limit position. After the limit of the plate 10, the limit plate 10 loses the thrust given by the current meshing tooth, the spring 9 drives the limit plate 10 to return to the original position, the next meshing tooth repeatedly pushes the limit plate 10 positively, and when the gear 7 performs When rotating in the opposite direction, that is, as image 3 As shown in the figure, when rotating counterclockwise, the meshing tooth exerts a reverse thrust on the limit plate 10, and the groove 8 is far away from the side wall of the cavity to limit the limit plate 10, and the two fit more closely. The bit plate 10 blocks the movement of the meshing teeth, and the gear 7 cannot rotate, which can effectively prevent the gear 7 from rotating in the opposite direction, thereby preventing the push rod 4 from moving upwards and being pulled out; the push rod 4 moves downwards to drive the elastic plate 12 to move downwards, elastic The plate 12 loses the restraint of the side wall of the cavity 2 and moves to the two sides of the grounding pile body 1 under the thrust of the spring 9 and is inserted into the soil to form a roughly eight-shaped structure, which can further fix the grounding pile body 1 , The fixing effect is better, it can effectively avoid the theft of the grounding stake and reduce the maintenance cost.

[0026] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection of the present invention. Within range.
