A ground anchor assembly for power grounding grid

Abstract

This utility model relates to the field of grounding equipment technology and discloses a ground anchor assembly for power grounding grids. It includes a grounding plate, a support frame welded to the top of the grounding plate, a hammer plate welded to the top of the support frame, and an anchor cylinder fixedly installed at the bottom of the grounding plate. The bottom end of the anchor cylinder is conical, and the interior of the anchor cylinder is hollow. Reinforcing components are movably installed on the side walls of the anchor cylinder. During installation, rotating the adjusting screw drives the lifting sleeve and the pressing cone block downwards, pushing two reinforcing protrusions out from the opening position, thereby enhancing the friction and stability between the anchor cylinder and the ground. When disassembling the entire ground anchor assembly later, rotating the adjusting screw in the opposite direction retracts the reinforcing protrusions into the anchor cylinder, reducing the friction between the anchor cylinder and the ground, thus facilitating the removal of the ground anchor assembly from the ground, avoiding damage to the ground anchor assembly, and meeting the needs for rapid disassembly and reuse of the ground anchor assembly.

Description

Technical Field

[0001] This utility model relates to the field of grounding equipment technology, and more specifically to a ground anchor component for power grounding grids. Background Technology

[0002] A power grounding grid, also known as a grounding electrode, is a metal conductor that is in direct contact with the earth. A grounding network connects multiple grounding electrodes using grounding trunk lines, offering reliable grounding and low grounding resistance. It is suitable for grounding a large number of electrical devices. During the installation of a power grounding grid, ground anchors are required for electrical connection between the grounding grid and the anchors.

[0003] Currently, when using ground anchors to connect to the grounding grid, simple positioning pins are often used. To improve the stability of the positioning pins when inserted into the ground, several protrusions are arranged on the surface of the positioning pins to enhance the tightness between the positioning pins and the ground. However, for some temporary grounding grid structures, after the grounding grid is assembled and connected using positioning pins, when it is necessary to disassemble and relocate the ground anchors later, it is often only possible to remove them by force. This method has the disadvantages of high labor intensity and slow removal speed. Furthermore, the ground anchors are easily damaged during the forceful removal process, affecting the secondary use of the ground anchor components.

[0004] In view of this, the present invention proposes a ground anchor assembly for power grounding grids to solve this problem. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a ground anchor assembly for power grounding grids to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a ground anchor assembly for a power grounding grid, including a grounding plate, a support frame welded to the top of the grounding plate, a hammer plate welded to the top of the support frame, an anchor cylinder fixedly installed at the bottom of the grounding plate, the bottom of the anchor cylinder being conical, the interior of the anchor cylinder being hollow, and a reinforcing component being movably provided on the side wall of the anchor cylinder.

[0007] The reinforcement component includes two symmetrical openings on the side wall of the anchor cylinder. The inner wall of the anchor cylinder is rotatably connected to a reinforcement protrusion via a pin. The reinforcement protrusion corresponds to the position of the opening. An adjusting screw is rotatably connected to the surface of the grounding plate. The bottom end of the adjusting screw extends into the interior of the anchor cylinder and is threadedly connected to a lifting sleeve. A pressing cone is fixedly installed at the bottom end of the lifting sleeve. The inclined surface of the pressing cone overlaps with the surface of the reinforcement protrusion.

[0008] Furthermore, a guide slide post is fixedly installed at the bottom end of the grounding plate, and a guide sleeve is fixedly installed on the surface of the lifting screw sleeve, with the guide sleeve slidably connected to the surface of the guide slide post.

[0009] As a further description of the above technical solution: by setting guide slides and guide sleeves, it is possible to prevent the lifting screw sleeve from rotating on the surface of the adjusting screw, thus ensuring that the lifting screw sleeve can move smoothly up and down.

[0010] Furthermore, two tension springs are fixedly installed on the inner bottom wall of the anchor cylinder, and the other end of the tension springs is fixed to the surface of the reinforcing protrusion, with the two tension springs being misaligned with each other.

[0011] As a further description of the above technical solution: when the squeezing effect of the squeezing cone on the reinforcing protrusion is eliminated, the reinforcing protrusion can be smoothly retracted into the anchor cylinder under the tension of the tension spring.

[0012] Furthermore, the inner wall of the anchor cylinder is fixedly equipped with a stop bar for limiting the position of the reinforcing protrusion.

[0013] As a further description of the above technical solution: by setting a stop bar, the position of the reinforcing protrusion in the retracted state can be limited, so as to avoid the difficulty of the extrusion cone in pushing the reinforcing protrusion out smoothly in the later stage.

[0014] Furthermore, two take-up drums are provided along the lower edge of the hammer plate, and grounding wires are provided on the surface of the take-up drums.

[0015] As a further description of the above technical solution: by setting up a take-up drum and a grounding wire, the grounding wire is bolted to the surface of the external equipment that needs to be grounded, which facilitates the electrical connection between the overall ground anchor assembly and the external equipment.

[0016] Furthermore, a take-up shaft is rotatably connected to the bottom end of the take-up drum. The take-up shaft extends into the interior of the take-up drum and a take-up reel is fixedly installed thereon. The grounding wire is wound around the surface of the take-up reel, and the end of the grounding wire is fixed to the take-up reel.

[0017] As a further description of the above technical solution: the grounding wire can be easily wound and wound up using a winding shaft and a take-up reel, and can be put away when not in use to achieve portability.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. Compared with existing technologies, this ground anchor assembly for power grounding grid uses an external hammer to drive a hammer plate, inserting the anchor cylinder into the ground for installation. During installation, rotating the adjusting screw drives the lifting sleeve and the pressing cone to move downwards, pushing out two reinforcing protrusions from the opening position. This enhances the friction and stability between the anchor cylinder and the ground. When the entire ground anchor assembly needs to be disassembled later, the adjusting screw can be rotated in the opposite direction to retract the reinforcing protrusions into the anchor cylinder, reducing the friction between the anchor cylinder and the ground. This facilitates the removal of the ground anchor assembly from the ground, preventing damage and meeting the needs for quick disassembly and reuse of the ground anchor assembly.

[0020] 2. Compared with existing technologies, this ground anchor assembly for power grounding grids, by setting guide slides and guide sleeves, can prevent the lifting screw sleeve from rotating on the surface of the adjusting screw, ensuring that the lifting screw sleeve can move smoothly up and down; by setting tension springs, when the squeezing effect of the extrusion cone on the reinforcing protrusion is eliminated, the reinforcing protrusion can be smoothly retracted into the anchor cylinder under tension; by setting stop bars, the position of the reinforcing protrusion in the retracted state can be limited, preventing the extrusion cone from having difficulty pushing the reinforcing protrusion out smoothly later; by setting take-up drums and grounding wires, the grounding wires can be bolted to the surface of the external equipment to be grounded, facilitating the electrical connection between the entire ground anchor assembly and the external equipment; by setting take-up shafts and take-up reels, the grounding wires can be easily wound and wound up, and can be retracted when not in use, achieving the purpose of portability.

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The ground anchor component for power grounding grid involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Reference Figures 1 to 4 This utility model provides a ground anchor assembly for power grounding grids, including a grounding plate 1, a support frame 2 welded to the top of the grounding plate 1, a hammer plate 3 welded to the top of the support frame 2, and an anchor cylinder 4 fixedly installed at the bottom of the grounding plate 1, the bottom end of the anchor cylinder 4 being conical.

[0028] During installation, the ground anchor assembly for the power grounding grid is installed by inserting the anchor cylinder 4 into the reserved hole of the externally laid grounding grid plate. Then, the external hammer body actuates the hammer plate 3 to insert the anchor cylinder 4 into the ground for installation. The grounding plate 1 is pressed against the external grounding grid plate to achieve the effect of installing and fixing the grounding grid plate.

[0029] The interior of the anchor tube 4 is hollow, and the sidewalls of the anchor tube 4 are movably equipped with reinforcement components.

[0030] The reinforcement component includes two symmetrical openings on the side wall of the anchor cylinder 4. The inner wall of the anchor cylinder 4 is rotatably connected to a reinforcement protrusion 5 via a pin. The reinforcement protrusion 5 corresponds to the position of the opening. The surface of the grounding plate 1 is rotatably connected to an adjusting screw 6. The bottom end of the adjusting screw 6 extends into the interior of the anchor cylinder 4 and is threadedly connected to a lifting sleeve 7. The bottom end of the lifting sleeve 7 is fixedly installed with a pressing cone 8. The inclined surface of the pressing cone 8 overlaps with the surface of the reinforcement protrusion 5.

[0031] During the installation of the overall ground anchor assembly, by rotating the adjusting screw 6, the lifting screw sleeve 7 and the pressing cone block 8 can be driven to move down, pushing the two reinforcing protrusions 5 out of the opening position, thereby enhancing the friction between the anchor cylinder 4 and the ground and improving the stability of the installation.

[0032] A guide slide post 9 is fixedly installed at the bottom of the grounding plate 1, and a guide sleeve 10 is fixedly installed on the surface of the lifting screw sleeve 7. The guide sleeve 10 is slidably connected to the surface of the guide slide post 9.

[0033] By setting guide slide 9 and guide sleeve 10, it is possible to prevent the lifting screw sleeve 7 from rotating on the surface of the adjusting screw 6, thus ensuring that the lifting screw sleeve 7 can move smoothly up and down.

[0034] Two tension springs 11 are fixedly installed on the inner bottom wall of the anchor cylinder 4. The other end of the tension spring 11 is fixed to the surface of the reinforcing protrusion 5, and the two tension springs 11 are offset from each other.

[0035] It is worth noting that when the entire ground anchor assembly needs to be disassembled later, the adjusting screw 6 can be rotated in the opposite direction. When the squeezing cone 8 is removed from the squeezing effect on the reinforcing protrusion 5, the reinforcing protrusion 5 can be smoothly retracted into the anchor cylinder 4 under the tension of the tension spring 11, reducing the friction between the anchor cylinder 4 and the ground. This makes it easier to remove the ground anchor assembly from underground, avoids damage to the ground anchor assembly, and meets the needs for quick disassembly and reuse of the ground anchor assembly.

[0036] The inner wall of the anchor cylinder 4 is fixedly equipped with a stop bar 12 for limiting the position of the reinforcing protrusion 5.

[0037] Furthermore, by setting the stop bar 12, the position of the reinforcing protrusion 5 in the retracted state can be limited, so as to prevent the squeezing cone 8 from having difficulty pushing the reinforcing protrusion 5 out smoothly when it is used again later.

[0038] Two take-up drums 13 are provided along the lower edge of the hammer plate 3, and a grounding wire 15 is provided on the surface of the take-up drum 13.

[0039] It is worth noting that by setting up the take-up drum 13 and the grounding wire 15, the grounding wire 15 is bolted to the surface of the external equipment that needs to be grounded, which facilitates the electrical connection between the overall ground anchor assembly and the external equipment.

[0040] The bottom end of the take-up drum 13 is rotatably connected to a take-up shaft 16. The take-up shaft 16 extends into the interior of the take-up drum 13 and is fixedly mounted on a take-up reel 14. A grounding wire 15 is wound around the surface of the take-up reel 14, and the end of the grounding wire 15 is fixed to the take-up reel 14.

[0041] Furthermore, the grounding wire 15 can be easily wound and wound up using the winding shaft 16 and the take-up reel 14, and can be put away when not in use to achieve portability.

[0042] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
