Description

Technical Field

[0001] This utility model relates to the field of conductive pile technology, specifically to a power grounding pile structure. Background Technology

[0002] A power grounding stake is a device used to safely conduct current from electrical equipment or systems into the ground. Its main functions include lightning protection, static electricity dissipation, and fault current conduction. It is typically made of conductive materials such as copper or steel and is installed vertically into the ground, relying on the conductivity of the metal in contact with the soil to achieve grounding.

[0003] Traditional grounding stakes require tools to drive them into the ground for installation. Then, cables are installed on the exposed upper part of the grounding stake, and the other end of the cable is electrically connected to the power equipment. However, current grounding stakes are mostly rods with smooth outer surfaces and limited contact area with the soil. They are prone to loosening due to soil shrinkage, frost heave, or mechanical vibration, which affects the conductivity. Utility Model Content

[0004] The purpose of this utility model is to provide a power grounding pile structure to solve the above problems, as detailed below.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This utility model provides a power grounding pile structure, including a pipe, a cone head fixedly connected to the lower end of the pipe, several layers of soil-inserting plates that can move radially along the lower side of the pipe, and several soil-inserting plates in each layer, a top partition plate fixedly connected to the upper end of the pipe, and a top support structure for driving several layers of soil-inserting plates to extend simultaneously on the top partition plate, and a clamping structure for fixing the conductor at the upper end of the pipe.

[0007] Preferably, each layer has three soil-insertion plates, which are evenly divided around the axis of the insertion tube, and the end of each soil-insertion plate is designed with an arc edge that matches the curvature of the circumference of the insertion tube.

[0008] Preferably, an insertion plate groove is provided through the side wall of the insertion tube, and the soil insertion plate is slidably connected in the insertion plate groove, which is opened radially along the insertion tube.

[0009] Preferably, a fixing block is fixedly connected in the insertion plate groove, and a movable groove that slides through the insertion plate to adapt to the fixing block is provided.

[0010] Preferably, the supporting structure includes a triangular prism located in the middle of the insertion tube. Each of the three side walls of the triangular prism is fixedly connected with a slope block that wedges with the inner end of the insertion plate. A threaded rod is rotatably connected between the inner bottom of the insertion tube and the top partition plate. A threaded hole is threaded through the triangular prism and threadedly connected to the threaded rod.

[0011] Preferably, the inner wall of the insertion tube is fixedly connected with three limiting strips to restrict the rotation of the triangular prism, and the limiting strips are located between two adjacent slope blocks.

[0012] Preferably, a magnetic plate is fixedly connected to the upper end of the triangular prism, and the magnetic plate is magnetically connected to the iron soil insertion plate.

[0013] Preferably, the top partition and the upper end of the insertion tube cooperate to form a storage cavity, and the clamping structure includes U-shaped grooves on both sides of the storage cavity, and the upper end of the insertion tube is threaded with an end cap.

[0014] Preferably, the upper end of the threaded rod extends to the top partition plate and is fixedly connected to a hexagonal nut head. An internal hexagonal fixing sleeve is fitted on the outside of the hexagonal nut head. A positioning pin is fixedly connected to one side of the internal hexagonal fixing sleeve. Several positioning holes for inserting the positioning pin are opened through the top partition plate.

[0015] Preferably, the length of the positioning pin is adapted to the depth of the storage cavity.

[0016] The beneficial effects are:

[0017] Rotating the hexagonal nut head causes the threaded rod to drive the triangular prism to rise vertically along the limiting strip. The inclined surface of the slope block engages with the wedge-shaped inner end of the soil insertion plate, pushing the three layers of soil insertion plates to extend radially synchronously. The grounding wire is embedded in the U-shaped groove, and the end cap is tightened to secure the wire, ensuring a low-resistance connection. After the soil insertion plate unfolds, the radial expansion increases the soil contact area, which improves the firmness of the insertion and prevents loosening after insertion into the soil. At the same time, the U-shaped groove integrates wire fixation and protection to prevent joint corrosion and improve practicality. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] See Figures 1-3 As shown, this utility model provides a power grounding pile structure, including a pipe 1, a cone head 3 fixedly connected to the lower end of the pipe 1, several layers of soil insertion plates 2 that can move radially along the lower side of the pipe 1, and several soil insertion plates 2 in each layer, the upper end of the pipe 1 is fixedly connected to a top partition plate 10, and the top partition plate 10 is provided with a support structure for driving several layers of soil insertion plates 2 to extend simultaneously, and the upper end of the pipe 1 is provided with a clamping structure for fixing the conductor.

[0026] As an optional implementation, each layer of soil-inserting plates 2 consists of three plates, which are evenly divided around the axis of the insertion tube 1. The end of each soil-inserting plate 2 has an arc edge design that matches the curvature of the circumference of the insertion tube 1. A plate groove 201 is provided through the side wall of the insertion tube 1, and the soil-inserting plates 2 are slidably connected in the plate groove 201. The plate groove 201 is opened radially along the insertion tube 1, which can push the three layers of soil-inserting plates 2 to extend radially at the same time (3 plates per layer, 9 plates in total). After the soil-inserting plates 2 are unfolded, the contact area is increased, and the radial expansion increases the soil contact surface. The arc edge of the soil-inserting plate 2 can be designed as a thin edge to improve the soil breaking effect when it extends.

[0027] Furthermore, a fixing block 202 is fixedly connected in the insertion plate groove 201, and a movable groove 203 that is slidably adapted to the fixing block 202 is provided through the soil insertion plate 2. The movable groove 203 and the fixing block 202 are slidably adapted to each other, which can prevent the soil insertion plate 2 from detaching from the insertion plate groove 201, and at the same time make the movement of the soil insertion plate 2 more stable.

[0028] Reference Figure 2 As shown, the supporting structure includes a triangular prism 4 located in the middle of the insertion tube 1. Slope blocks 5, which wedge with the inner end of the insertion plate 2, are fixedly connected to the three side walls of the triangular prism 4. A threaded rod 8 is rotatably connected between the inner bottom of the insertion tube 1 and the top partition plate 10. A threaded hole 7, threaded to the threaded rod 8, is opened through the triangular prism 4. Rotating the hexagonal nut head 11 causes the threaded rod 8 to drive the triangular prism 4 to rise vertically along the limiting strip 6. Through the wedge-shaped engagement of the slope block 5 with the inner end of the insertion plate 2, the three layers of insertion plates 2 are pushed to extend radially synchronously. The thread on the threaded rod 8 consists of three segments, with the remaining portion of the three segments being a smooth axis. This configuration ensures that when the triangular prism 4 moves to the end of the threaded segment on the threaded rod 8 (i.e., the junction with the smooth axis), the threaded rod 8 cannot continue to rotate, thus indicating that the threaded rod 8 has reached its designated position.

[0029] Specifically, three limiting strips 6 are fixedly connected to the inner wall of the insertion tube 1 to restrict the rotation of the triangular prism 4, and the limiting strips 6 are located between two adjacent slope blocks 5. The limiting strips 6 can restrict the rotation of the triangular prism 4 and the three slope blocks 5, so that the threaded rod 8 can stably drive the triangular prism 4 to rise when rotating.

[0030] Furthermore, a magnetic plate 9 is fixedly connected to the upper end of the triangular prism 4. The magnetic plate 9 is magnetically connected to the iron soil insertion plate 2. The magnetic plate 9 can attract and fix the soil insertion plate 2, ensuring that the soil insertion plate 2 is in a retracted state when the insertion tube 1 is inserted into the ground.

[0031] As an optional implementation, the top partition 10 and the upper end of the insertion tube 1 cooperate to form a receiving cavity. The clamping structure includes U-shaped grooves 12 opened on both sides of the receiving cavity. The upper end of the insertion tube 1 is threadedly connected to an end cap 13, which can embed the grounding wire into the U-shaped groove 12. Tightening the end cap 13 can press the wire to ensure a low-resistance connection. At the same time, the end cap 13 can be installed during the piling process to protect the upper end of the insertion tube 1 and prevent damage to the receiving cavity during the piling process.

[0032] As an optional implementation, the upper end of the threaded rod 8 extends to the top partition plate 10 and is fixedly connected to a hexagonal nut head 11. An internal hexagonal fixing sleeve 14 is fitted on the outside of the hexagonal nut head 11. A positioning pin 15 is fixedly connected to one side of the internal hexagonal fixing sleeve 14. Several positioning holes 16 are opened through the top partition plate 10 to be inserted into the positioning pin 15. After the threaded rod 8 rotates to a suitable number of turns, the internal hexagonal fixing sleeve 14 is fitted on the outside of the hexagonal nut head 11, and at the same time, the positioning pin 15 is inserted into the positioning hole 16 to lock the threaded rod 8 and prevent reverse rotation.

[0033] Specifically, the length of the positioning pin 15 is adapted to the depth of the receiving cavity. By setting a longer positioning pin 15, the upward movement range of the internal hexagonal fixing sleeve 14 is limited after the end cover 13 is installed, so that the positioning pin 15 cannot be pulled out of the positioning hole 16, thus achieving the locking effect of the positioning pin 15 and the internal hexagonal fixing sleeve 14 on the threaded rod 8.

[0034] The working principle of this utility model:

[0035] Insert the insertion tube 1 vertically into the ground. The cone head 3 breaks through the hard surface soil and guides the pile to the target depth. The outer wall of the insertion tube 1 naturally adheres to the soil, forming a foundation grounding path. Rotate the hexagonal nut head 11 to make the threaded rod 8 drive the triangular prism 4 to rise vertically along the limiting strip 6. Through the inclined surface of the slope block 5 and the wedge-shaped engagement of the inner end of the soil insertion plate 2, push the three layers of soil insertion plates 2 to extend radially synchronously (3 pieces per layer, 9 pieces in total). Embed the grounding wire into the U-shaped groove 12, tighten the end cap 13 to press the wire, and ensure a low resistance connection. Insert the positioning pin 15 into the positioning hole 16 of the top partition plate 10 to lock the hexagonal nut head 11 to prevent reverse rotation.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
