The axial outer wall of the grounding column body 10 is annularly provided with multiple layers of evenly distributed telescopic holes 25, and the inside of the telescopic hole 25 is elastically and telescopically provided with a transverse reinforcement rod 22, and when the transverse reinforcement rod 22 is in a free state, the transverse reinforcement rod 22 is controlled to be The outer end of the horizontal reinforcement rod 22 is received in the telescopic hole 25, and the inner end of the horizontal reinforcement rod 22 is provided with a group of lifting and lowering push components. The top of the lifting and lowering push components extends into the connecting tube 12. When the lifting and lowering push components move up and down, radial thrust is applied to the inner end of the horizontal reinforcement rod 22 in contact with the horizontal reinforcement rod 22, and then cooperates with the elastic effect of the horizontal reinforcement rod 22 itself to realize the outer end of the horizontal reinforcement rod 22 moving outward along the telescopic hole 25, thereby applying a vertical limiting force to the grounding column body 10, thereby increasing the difficulty of pulling up the grounding column body 10, and improving the anti-theft ability of the grounding column body 10 after installation.
[0018] In the embodiment of the present invention, the diameter of the limiting ring 11 is larger than the top diameter of the grounding column body 10, and is used to limit the depth range of the grounding column body 10 inserted downward into the soil, and a plurality of plug rods are installed at equal intervals in a ring at the bottom of the limiting ring 11. After the grounding column body 10 is fully inserted into the ground, the limiting ring 11 is synchronously lowered to drive the plug rods to be inserted into the ground until the bottom surface of the limiting ring 11 contacts the ground surface, and then, under the restriction of the plug rods, the axial rotation of the grounding column body 10 is prevented and the stability of the grounding column body 10 after being plugged into the ground is enhanced; the outer end of the horizontal reinforcement rod 22 is also set to a conical structure, which is convenient for reducing the plug-in resistance between the ground and the soil and improving the smoothness of movement; it extends into the connecting tube 12 A reinforcement control port 13 is provided on the side wall of the connection tube 12 on one side of the lifting push assembly at the bottom. The reinforcement control port 13 is convenient for the staff to directly control the lifting push assembly, so as to control the movement of the horizontal reinforcement rod 22. An opening and closing plate 14 is hinged on one side of the reinforcement control port 13. The opening and closing of the reinforcement control port 13 is controlled by the opening and closing plate 14. A locking device is provided on the opening and closing plate 14 for arbitrarily opening the opening and closing plate 14 to affect the anti-theft strength. After controlling the lifting push assembly and moving the horizontal reinforcement rod 22 radially to the inside of the soil, the opening and closing plate 14 is welded in the reinforcement control port 13 to fully close the reinforcement control port 13, that is, to increase the full sealing of the inside of the connection tube 12;
[0019] Specifically, the locking device can be fixed with a lock to ensure safe closure while facilitating subsequent opening.
[0020] In one embodiment of the present invention, the lifting and pushing assembly includes a lifting and reinforcing rod 18 that is lifted and lowered along the axis of the grounding column body 10. A thrust slot 19 is provided on the outer wall of the lifting and reinforcing rod 18 corresponding to each vertical row of telescopic holes 25. The inner side of the thrust slot 19 is set to an inclined structure (distributed in a shallow upper and deep lower direction in the radial direction). When the transverse reinforcing rod 22 is in a free state, its inner end moves to the deepest position at the lower end of the thrust slot 19. As the lifting and reinforcing rod 18 descends, the inner end of the transverse reinforcing rod 22 is gradually subjected to a radial outward thrust, thereby pushing the transverse reinforcing rod 22 to extend outward. A spring positioning ring 23 is installed on the outer wall of the rod 22 close to the inner wall of the grounding column body 10, and a sleeve spring 24 is elastically sleeved between the spring positioning ring 23 and the inner wall of the grounding column body 10, that is, when the sleeve spring 24 is used to keep the transverse reinforcement rod 22 in a free state, the outer end extends to the inside of the telescopic hole 25, and when the thrust of the thrust slide groove 19 is lost, the transverse reinforcement rod 22 can be automatically reset, thereby achieving that after the grounding column body 10 is completely plugged into the ground, the transverse reinforcement rod 22 is controlled to be radially plugged into the soil by the downward movement of the lifting reinforcement rod 18, thereby preventing the grounding column body 10 from moving in the vertical direction;
[0021] A connecting block 20 is installed on the top of the lifting reinforcement rod 18, and a rotating groove is provided inside the connecting block 20. A rotating block 21 is limitedly connected in the rotating groove. A threaded rod 17 is connected to the top of the rotating block 21 through a connecting rod. An internal threaded hole that runs through the grounding column body 10 and the connecting tube 12 is provided in the middle of the limiting ring 11. The threaded rod 17 is placed in the internal threaded hole and connected by threads. A hexagonal rod 15 is fixedly connected to the top of the threaded rod 17. The rotating connection between the rotating block 21 and the rotating groove, and the threaded connection of the threaded rod 17 in the internal threaded hole are matched with the hexagonal rod 15 placed at the reinforcement control port 13, so as to control the hexagonal rod 15 to drive the threaded rod 17 to rotate, thereby controlling the threaded rod 17 to move up and down, and then driving the lifting reinforcement rod 18 to move vertically inside the grounding column body 10, so as to realize the radial movement control of the horizontal reinforcement rod 22;
[0022] The bottom end of the lifting reinforcement rod 18 is set to a conical structure that cooperates with the bottom of the grounding column body 10, in order to control the lifting reinforcement rod 18 when lifting and lowering, and expand its lifting range inside the grounding column body 10;
[0023] The diameter of the spring positioning ring 23 is smaller than the width of the thrust slot 19 , that is, when the transverse reinforcement rod 22 is subjected to radial thrust, the sleeve spring 24 is compressed and the spring positioning ring 23 moves radially synchronously, and the spring positioning ring 23 can also enter the thrust slot 19 at this time.
[0024] As a preferred embodiment of the present invention, in order to prevent the lifting reinforcement rod 18 from rotating when moving up and down and affecting the smooth and accurate contact between the inner end of the horizontal reinforcement rod 22 and the thrust groove 19, a limited rotation rod 26 is installed on the outer wall of the lifting reinforcement rod 18 between adjacent thrust grooves 19, and a slide rail is provided on the inner wall of the grounding column body 10 corresponding to the end of the limited rotation rod 26. The limited rotation rod 26 moves along the slide rail, thereby preventing the lifting reinforcement rod 18 from rotating and deviating.
[0025] The working principle of the utility model is: in the idle position of the device, all the driving parts mentioned above, which refer to the power elements, electrical components and the adapted power supply, are connected through wires, and the electrical connection between the electrical components is completed in a sequential working order. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process, and does not explain the electrical control. When in use, the grounding column body 10 is pre-inserted under the ground to be used until the bottom plug of the limit ring 11 is inserted into the soil, and then the opening and closing plate 14 is opened, and the hexagonal rod 15 is controlled to rotate to drive the threaded rod 17 rotates and moves downward, and then under the connection between the rotating block 21 and the rotating groove, the lifting reinforcement rod 18 is driven to move downward. As the lifting reinforcement rod 18 moves, the thrust slide groove 19 contacts the inner end of the horizontal reinforcement rod 22, gradually pushing the horizontal reinforcement rod 22 to extend outward and insert it into the soil outside the telescopic hole 25. At this time, the grounding column body 10 is fixed in the vertical direction, and then the grounding column body 10 is completely fixed by the insertion of the plug rod and the grounding column body 10 itself, and then the reinforcement control port 13 is closed to ensure the full anti-theft ability of the grounding column.
[0026] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
