Description

TECHNICAL FIELD

[0001] The application relates to the technical field of grounding piles, in particular to a grounding pile for electric power engineering. BACKGROUND

[0002] In the implementation process of electric power engineering, it is a crucial safety measure to ensure the effective grounding of electrical equipment or high-voltage power grids, aiming to significantly reduce the risk of lightning strikes and the probability of electric leakage accidents. As a key component to achieve this safety goal, the grounding pile traditionally completes the grounding task by driving a metal rod deep into the ground and forming an electrical connection with the soil. Subsequently, a grounding wire is wound and fixed on the grounding pile to build a complete grounding system.

[0003] For a long time, the installation of grounding piles mainly relies on the method of external force hammering, that is, directly hammering the grounding pile into the soil. However, this method has significant defects: the interaction force between the grounding pile and the soil is limited, resulting in insufficient stability of the grounding pile, which is easily pulled out under external force, thereby affecting the grounding effect. In order to solve this problem, the industry generally tries to add multiple protruding parts (such as spiral threads, conical spikes, etc.) to the outer surface of the grounding pile, aiming to improve the stability and grounding efficiency of the grounding pile by increasing the contact area and friction with the soil.

[0004] Although this design enhances the grounding performance of the grounding pile to some extent, it also brings new problems. The presence of protruding parts significantly increases the resistance that needs to be overcome by the grounding pile during insertion into the soil, making the installation process more difficult, consuming a lot of manpower and resources, and possibly damaging the protruding parts due to improper operation, thereby affecting the overall structure and grounding effect of the grounding pile. Therefore, how to ensure good grounding performance of the grounding pile while optimizing its design to improve installation convenience and durability has become a key problem in the current grounding technology of electric power engineering. CONTENT OF THE INVENTION

[0005] In order to improve the convenience and stability of the installation of the grounding pile on the ground, the application provides a grounding pile for electric power engineering.

[0006] The grounding pile for electric power engineering provided by the application adopts the following technical scheme:

[0007] A grounding pile for electric power engineering, comprising a pile body and a deployment assembly, the pile body has a movable cavity, the movable cavity movably installs a movable plate, the movable plate is installed with a plurality of insertion rods; all the outer walls of the movable plates are collectively sleeved with an elastic rope, the elastic rope is used to make all the movable plates fold towards each other; the pile body is provided with an insertion slot in communication with the movable cavity, and the deployment assembly is used to drive the insertion rods to be exposed outside the pile body.

[0008] By adopting the technical scheme, the insertion rod can be kept in a folded state under the action of the elastic rope, facilitating the insertion operation of the grounding pile. Meanwhile, the unfolding assembly can effectively drive the insertion rod to extend out of the pile body from the insertion slot, realizing automatic unfolding of the insertion rod after the grounding pile is inserted into the ground, thereby increasing the contact area and the acting force between the grounding pile and the soil, significantly improving the overall stability of the grounding pile, and avoiding the situation that the grounding pile is easily pulled out due to external force.

[0009] Optionally, an end of the insertion rod away from the movable plate is provided as a pointed end.

[0010] By adopting the technical scheme, the insertion rod can be kept in a folded state under the action of the elastic rope, facilitating the insertion operation of the grounding pile. Meanwhile, the unfolding assembly can effectively drive the insertion rod to extend out of the pile body from the insertion slot, realizing automatic unfolding of the insertion rod after the grounding pile is inserted into the ground, thereby increasing the contact area and the acting force between the grounding pile and the soil, significantly improving the overall stability of the grounding pile, and avoiding the situation that the grounding pile is easily pulled out due to external force.

[0011] Optionally, the movable plate is provided in two groups, the unfolding assembly comprises a rotating rod, a mounting piece and a driving piece, the mounting piece is mounted in the movable cavity, and the mounting piece is located between the two movable plates; the rotating rod is rotatably mounted on the mounting piece, and the two ends of the rotating rod are used to abut against the sides of the two movable plates away from each other; and the driving piece is used to drive the rotating rod to rotate.

[0012] By adopting the technical scheme, when it is necessary to unfold the insertion rod to enhance the stability of the grounding pile, the driving piece can effectively drive the rotating rod to rotate. With the rotation of the rotating rod, the two ends thereof gradually push the two movable plates away from each other, so that the insertion rod extends out of the pile body from the insertion slot.

[0013] Optionally, the driving piece comprises a driving rod and a positioning portion, the rotating rod is provided with a sliding slot, a sliding block is mounted in the sliding slot, one end of the driving rod is hingedly connected with the sliding block, a driving slot is formed in the upper surface of the pile body and is in communication with the movable cavity, the other end of the driving rod is arranged to protrude out of the driving slot to the outside, and the positioning portion is used to fix the rotating rod and the inner wall of the driving slot.

[0014] By adopting the technical scheme, one end of the driving rod is hingedly connected with the sliding block, and the other end thereof protrudes out of the driving slot to the outside. When it is necessary to unfold the insertion rod to enhance the stability of the grounding pile, an operator can pull the driving rod through external action, drive the sliding block to move in the sliding slot, and thus push the rotating rod to rotate. The rotation of the rotating rod will cause the two ends thereof to abut against the two movable plates and apply a pushing force, so that the movable plates are opened outward against the constraint of the elastic rope, and thus the insertion rod extends out of the pile body from the insertion slot. Meanwhile, the positioning portion can fix the rotating rod to the inner wall of the driving slot, so as to ensure that the rotating rod remains in a stable state, realize effective unfolding of the insertion rod, and improve the stability of the grounding pile.

[0015] Optionally, the positioning part comprises a first threaded part arranged in the driving slot and a second threaded part arranged on the outer wall of the driving rod, and the first threaded part is matched with the second threaded part.

[0016] By using the above technical scheme, the matching of the first threaded part and the second threaded part can realize the stable fixation between the rotating rod and the inner wall of the driving slot. Specifically, during the operation, the user can rotate the driving rod to make the first threaded part and the second threaded part engage or separate from each other, so as to conveniently complete the locking or unlocking action of the position of the rotating rod. This design not only improves the overall stability of the structure, but also simplifies the operation process, so that the operation of the unfolding assembly is more convenient and reliable.

[0017] Optionally, the positioning part comprises a fixing block and a spring, the outer wall of the driving rod is provided with a first movable slot, the fixing block is movably installed in the first movable slot, the inner wall of the driving slot is provided with a second movable slot for inserting the fixing block; the two ends of the spring are connected with the fixing block and the first movable slot respectively, and the elastic force of the spring is used to drive the fixing block to move away from the first movable slot.

[0018] By using the above technical scheme, the spring is arranged to enable the fixing block to automatically reset and be clamped into the second movable slot after the movement of the driving rod, so as to realize the quick locking of the position of the driving rod and improve the operation convenience.

[0019] Optionally, when the movable plate is in the folded state, the end of the insertion rod away from the movable plate is partially located in the movable slot.

[0020] By using the above technical scheme, when the pile body is inserted into the ground, the end of the insertion rod away from the movable plate is partially kept in the movable slot, which can effectively prevent the insertion rod from being completely pulled out of the insertion slot due to external force, thereby ensuring the structural stability.

[0021] Optionally, the outer wall of the insertion rod is provided with a groove.

[0022] By using the above technical scheme, the groove arranged on the outer wall of the insertion rod can increase the contact area between the insertion rod and the soil. When the insertion rod is inserted into the soil, the groove structure can effectively improve the friction between the soil and the insertion rod, thereby enhancing the overall stability of the grounding pile and reducing the possibility of accidental pulling out of the grounding pile.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] 1. By setting the elastic rope and the unfolding assembly, the insertion rod can be kept in the retracted state under the action of the elastic rope, facilitating the insertion operation of the grounding pile; the unfolding assembly can effectively drive the insertion rod to extend out of the insertion slot to the outside of the pile body, increase the contact area and force between the grounding pile and the soil, and significantly improve the overall stability of the grounding pile, avoiding the situation that the grounding pile is easily pulled out due to external force;

[0025] 2. By setting the groove, the contact area between the insertion rod and the soil can be increased, and when the insertion rod is inserted into the soil, the groove structure can effectively increase the friction between the soil and the insertion rod. BRIEF DESCRIPTION OF DRAWINGS
