Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering, in particular to an electric power engineering grounding pile. Background Art

[0002] Power transmission lines and related equipment are mostly located outdoors and are easily struck by lightning. Line tripping due to lightning strikes often occurs. In order to prevent lightning strikes, grounding devices need to be installed on the transmission lines to guide the current generated by lightning strikes to the ground to prevent the wires or transmission equipment from being damaged by lightning voltage. The grounding device needs to be reliably grounded, usually using metal grounding piles.

[0003] For example, patent publication number CN213816445U is a power grounding pile used in power engineering. After the inverted "concave" shaped support block is placed on the ground, the support block supports the main body of the power grounding pile to avoid shaking of the main body of the power grounding pile during the knocking and installation process. At the same time, it avoids the need for workers to support it with their hands, which may cause injuries during the knocking process, thereby improving overall safety.

[0004] Although the above-mentioned device supports the main body of the power grounding pile by placing an inverted "concave" shaped support block on the ground, the stability of the grounding pile when inserted into the ground is relatively poor, and the work intensity of inserting the grounding pile into the ground is relatively large. The operation of inserting the grounding pile into the ground is relatively inconvenient, and the grounding pile cannot be limited after being inserted into the ground. Therefore, we propose a new type of power engineering grounding pile. Utility Model Content

[0029] like Figure 2As shown, it should be noted that: by setting the fixing rod 2, before grounding, the fixing rod 2 first penetrates into the ground to stabilize the device body on the ground, and at the same time limits the device theme, and is threadedly connected with the drill bit 1 and the top cover 10 through the fixing tube 5, which facilitates the disassembly and replacement of various parts of the device, thereby improving the practicability of the device.

[0030] The limiting mechanism 8 comprises:

[0031] A bearing 803 is installed on the inner side of the top of the drill bit 1, a threaded rod 806 is installed on the inner wall of the bearing 803, a fixed disk 802 is installed on the outer wall of the top of the threaded rod 806, a rotating block 801 is installed on the top of the fixed disk 802, and a bearing 803 is installed on the outer wall of the threaded rod 806 near the top, and the bearing 803 is located on the inner side of the top cover 10.

[0032] A mounting seat 810 is installed on the outer wall of the threaded rod 806, and multiple clamps 809 are installed on the outer wall of the mounting seat 810.

[0033] like Figure 4 As shown, it should be noted that: when the fixed cylinder 5 enters below the ground, rotating the rotating block 801 can drive the fixed disk 802 to rotate, and the fixed disk 802 drives the threaded rod 806 to rotate during the rotation, and the threaded rod 806 drives the mounting seat 810 to move up and down during the rotation.
