Description

Technical Field

[0001] This utility model relates to the field of power safety protection technology, and in particular to a grounding wire installation auxiliary device. Background Technology

[0002] Grounding wires are used in power systems to conduct electrical charges from equipment or lines to the ground, and are an important facility for ensuring electrical safety. During grounding wire installation, auxiliary devices are often used to drive the grounding rod into the ground and establish a conductive connection between the grounding wire and the grounding rod to ensure smooth charge conduction. However, in existing technologies, some auxiliary devices manually drive the grounding rod into the ground, which is not only laborious and inefficient, but also makes it difficult to accurately control the driving depth. Furthermore, the grounding wire and grounding rod often rely on simple clamps, which are prone to loosening due to vibration or external forces, leading to poor conductive contact. Therefore, those skilled in the art provide a grounding wire installation auxiliary device to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a grounding wire installation auxiliary device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A grounding wire installation auxiliary device includes an insulating tube and a grounding wire lug. The top of the insulating tube is fixedly connected to a junction box, and a grounding rod is provided inside the junction box. A groove is opened on one side of the junction box, and a conductive pad is fixedly installed on the inner wall of the groove. A spiral spring cable is connected to the bottom of the conductive pad. The insulating tube is provided with a drive assembly, which includes a planetary roller nut that is rotatably disposed inside the insulating tube and a planetary roller screw that is slidably disposed inside the insulating tube. The two are dynamically engaged with the planetary rollers through a helical raceway, and the bottom end of the planetary roller screw is fixedly connected to the top end of the grounding rod. The helical spring cable passes through the planetary roller screw and is connected to the grounding rod; The junction box has a hinged sealing cover at the groove, and a pressing component is provided on its inner side. When the sealing cover is closed, the pressing component presses the grounding wire copper lug between the conductive gasket and the sealing cover. The sealing cover is provided with a fixing component for locking the position of the sealing cover when it is closed.

[0005] As a further embodiment of this utility model, the drive assembly also includes a drive box sleeved on the outer wall of the insulating tube, inside which a drive gear and a motor for driving the drive gear are rotatably arranged; the outer wall of the planetary roller nut is fixed with a driven gear, which meshes with the drive gear.

[0006] As a further embodiment of this utility model, a limiting post is fixed at the top of the planetary roller screw, and a limiting rod is axially provided on the inner wall of the insulating tube; a sliding groove is opened on the outer wall of the limiting post to slide in cooperation with the limiting rod.

[0007] As a further improvement of this utility model, a lithium battery for powering the motor is fixedly installed on the drive box.

[0008] As a further embodiment of this utility model, the pressing assembly includes a pressing block that slides within a groove opened inside the sealing cover, and an arc-shaped spring sheet with one end fixed to the inner wall of the groove and the other end slidably connected to clearance grooves opened on both sides of the inner wall of the groove; the arc surface of the spring sheet abuts against the bottom of the pressing block, driving it to press against the copper lug of the grounding wire. As a further embodiment of this utility model, a horn tube is fixed to the bottom of the insulating tube, and two foot pedals are symmetrically hinged thereto. A torsion spring is sleeved on the foot pedal shaft, and the two ends of the torsion spring abut against the shaft and the outer wall of the horn tube, respectively.

[0009] As a further embodiment of this utility model, the fixing component includes two pins slidably disposed in the sliding cavity of the sealing cover, with a spring abutting between the two pins; a sliding opening communicating with the sliding cavity is opened on the side wall of the sealing cover, and a toggle block connected to the corresponding pin is slidably disposed in the sliding opening; pin holes that cooperate with the pins are opened on the inner walls of both sides of the groove, and when the sealing cover is closed, the two pins are respectively inserted into the corresponding pin holes.

[0010] As a further improvement of this utility model, a cone head is fixed at the bottom end of the grounding rod.

[0011] The beneficial effects of this utility model are as follows: 1. The motor in the drive box drives the drive gear to rotate, which in turn drives the driven gear fixed to the planetary roller nut, thereby causing the planetary roller nut to rotate. This efficiently converts the rotational motion into the powerful linear downward pressure of the planetary roller screw, which allows the grounding rod to be easily, effortlessly, and controllably inserted into the ground to the required depth. This significantly reduces the operational burden, improves installation efficiency and depth accuracy, and ensures that the grounding rod can be reliably embedded in the ground to achieve effective grounding.

[0012] 2. By using a horn-shaped tube at the bottom of the insulating tube in conjunction with a hinged foot pedal and torsion spring, the device can adapt to different ground angles and maintain stable support. The foot pedal, under the action of the torsion spring, adheres to the ground, providing a stable footing point, effectively ensuring the overall stability of the device when operating on slopes or irregular ground, improving operational safety and adaptability to complex environments.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. It should be noted that, unless otherwise expressly specified and limited, the terms "installation", "connection", and "setting" should be interpreted broadly. For those skilled in the art, the specific meaning of the above terms in this patent can be understood according to the specific circumstances.

[0016] Reference Figures 1-6 A grounding wire installation auxiliary device includes an insulating tube 1 and a grounding wire lug 14. The insulating tube 1, as the supporting body of the overall device, is made of insulating material to effectively avoid the risk of leakage during operation. A junction box 4 is fixedly connected to the top of the insulating tube 1, and the junction box 4 is connected to the interior of the insulating tube 1 to form an integral structure. A grounding rod 5 is provided inside the insulating tube 1. The grounding rod 5 can move along the axial direction of the insulating tube 1, and a cone 24 is fixedly connected to its bottom end. The cone 24 is sharp, which can more easily penetrate the ground when the grounding rod 5 moves downward, reducing insertion resistance. A groove is opened on one side of the junction box 4 for placing the grounding wire lug 14. A conductive pad 12 is fixedly provided on the inner wall of one side of the groove. The conductive pad 12 is made of a material with good conductivity to ensure smooth current conduction.

[0017] A helical spring cable 13 is fixedly connected to the bottom of the conductive pad 12. The helical spring cable 13 is elastic and can extend and retract with the movement of the grounding rod 5. One end of the cable passes through the planetary roller screw 7 (mentioned later) and is fixedly connected to the grounding rod 5, thereby ensuring a good electrical path is always maintained between the grounding rod 5 and the conductive pad 12, preventing wire breakage or poor contact due to the movement of the grounding rod 5. An insulating tube 1 is equipped with a drive assembly for inserting a grounding rod 5 into the ground. The drive assembly includes a drive housing 2, which is fixedly sleeved on the outer wall of the insulating tube 1, providing protection and support for the internal components. A lithium battery 3 is installed on the drive housing 2, providing power to the motor 10 in the drive assembly to ensure its normal operation. Inside the drive housing 2, a drive gear 9 is rotatably mounted, and the motor 10 is fixedly mounted. The output end of the motor 10 is connected to the drive gear 9; when the motor 10 is started, it drives the drive gear 9 to rotate. A planetary roller nut 6 is rotatably mounted inside the insulating tube 1. A driven gear 8 is fixedly sleeved on the outer wall of the planetary roller nut 6. The driven gear 8 meshes with the drive gear 9. When the drive gear 9 rotates under the drive of the motor 10, it drives the driven gear 8 to rotate synchronously, thereby causing the planetary roller nut 6 to rotate within the insulating tube 1. A planetary roller screw 7 is also slidably installed inside the insulating tube 1. The helical raceway of the planetary roller screw 7 dynamically meshes with the planetary rollers of the planetary roller nut 6. Through this meshing relationship, the rotation of the planetary roller nut 6 can efficiently convert the rotational motion into the linear motion of the planetary roller screw 7, causing the planetary roller screw 7 to generate a strong linear downward pressure. A limit post 11 is fixedly installed at the top of the planetary roller screw 7, and a limit rod 1101 is axially installed on the inner wall of the insulating tube 1. The outer wall of the limit post 11 has a groove corresponding to the limit rod 1101 and is slidably connected to the limit rod 1101. This structure can effectively prevent the planetary roller screw 7 from rotating with the planetary roller nut 6, ensuring that the planetary roller screw 7 only moves axially. The bottom end of the planetary roller screw 7 is fixedly connected to the grounding rod 5. When the planetary roller screw 7 moves downward in a straight line, it will drive the grounding rod 5 to move downward synchronously, so that the grounding rod 5 can be easily, effortlessly and controllably inserted into the ground to the required depth, significantly reducing the operating burden, improving installation efficiency and depth accuracy, and ensuring that the grounding rod 5 can be reliably embedded in the ground to achieve effective grounding.

[0018] A horn tube 21 is fixedly fitted to the bottom of the insulating tube 1. The horn tube 21 increases the contact area with the ground, improving the stability of the device during placement. Two foot pedals 22 are symmetrically rotatably mounted on the horn tube 21. Each foot pedal 22 has a torsion spring 23 mounted on its pivot shaft. The two ends of the torsion springs 23 abut against the pivot shaft of the corresponding foot pedal 22 and the outer wall of the horn tube 21, respectively. Under the action of the torsion springs 23, the foot pedals 22 can adjust their angle according to the ground conditions, making them fit the ground and providing stable support for the device. They also provide a stable footing point for the operator, effectively ensuring the overall stability of the device when operating on slopes or irregular ground, improving operational safety and adaptability to complex environments.

[0019] Junction box 4 has a hinged sealing cover 15 at the recessed area. The sealing cover 15 can rotate around the hinge to open and close the recess. A fixing component is provided on the sealing cover 15 to fix its position when closed. The fixing component includes two pins 16, which are slidably disposed within a sliding cavity on the sealing cover 15. The sides of the two pins 16 that are close to each other abut against the same spring 17. Pin holes corresponding to the pins 16 are provided on both inner walls of the recess. A sliding opening communicating with the sliding cavity is provided on one side of the sealing cover 15. Two actuating blocks 18 are slidably disposed within the sliding opening, both extending into the sliding cavity and fixedly connected to their corresponding pins 16. When the sealing cover 15 is closed, the two pins 16 are inserted into their corresponding pin holes under the elastic force of the spring 17, locking the sealing cover 15 in place. To open the sealing cover 15, the actuating blocks 18 drive the pins 16 to compress the spring 17, causing the pins 16 to retract from their pin holes.

[0020] A clamping assembly is provided inside the sealing cover 15. When the sealing cover 15 is closed, the grounding copper lug 14 is clamped between the conductive pad 12 and the clamping assembly. The clamping assembly includes a groove formed inside the sealing cover 15, a pressing block 19 slidably connected in the groove, and an arc-shaped spring plate 20 provided in the groove. One end of the spring plate 20 is fixedly connected to the inner walls of both sides of the groove, and the other end is slidably connected to the clearance grooves formed in the inner walls of both sides of the groove. The arc surface of the spring plate 20 abuts against the bottom of the pressing block 19. During the closure of the sealing cover 15, the arc-shaped spring plate 20 is compressed and deformed. Its arc surface continuously pushes the pressing block 19, causing the pressing block 19 to move towards the conductive pad 12, thereby tightly pressing the grounding copper lug 14 between the two onto the conductive pad 12, ensuring a good electrical connection between the grounding copper lug 14 and the conductive pad 12.

[0021] Working Principle: During operation, the device is placed at the target position, with the horn tube 21 contacting the ground. Depending on the ground conditions, the foot pedal 22 can be adjusted in angle under the action of the torsion spring 23, providing stable support. The motor 10 inside the drive box 2 is started, driving the drive gear 9 to rotate. The drive gear 9 meshes with the driven gear 8 fixed on the planetary roller nut 6, driving the planetary roller nut 6 to rotate within the insulating tube 1. The rotation of the planetary roller nut 6 is converted into a powerful linear downward movement of the planetary roller screw 7 through the dynamic meshing of its planetary rollers and the helical raceway of the planetary roller screw 7. The limiting post 11 is slidably connected to the limiting rod 1101 on the inner wall of the insulating tube 1 via its outer wall groove, effectively preventing the rotation of the planetary roller screw 7 and ensuring that it only moves axially. The planetary roller screw 7 drives the grounding rod 5, fixed to its bottom end, to forcefully insert downwards into the ground. The helical spring 13 connects the conductive pad 12 and the grounding rod 5, ensuring electrical continuity and accommodating the movement of the grounding rod 5.

[0022] After the grounding rod 5 is inserted into place, the grounding wire lug 14 is placed on the conductive pad 12 in the groove of the junction box 4. The hinged sealing cover 15 is then closed. During the closing process of the sealing cover 15, its inner pressing component operates: the pressing block 19 slides in the inner groove of the sealing cover 15, and its bottom is pushed by the arc surface of the arc spring 17, which is fixed at one end and slides in the relief groove at the other end. As the sealing cover 15 closes, the arc spring 17 is deformed by pressure, and its arc surface continues to push the pressing block 19, causing it to move strongly towards the conductive pad 12, thereby tightly pressing the grounding wire lug 14 between the two onto the conductive pad 12. At this time, the lug is reliably clamped between the conductive pad 12 and the pressing block 19, forming a stable electrical connection. At the same time, the two pins 16 are inserted into the pin holes on the inner walls of the groove under the action of elasticity, realizing the position locking after the two sealing covers 15 are closed. The grounding wire achieves a reliable electrical connection with the top of the grounding rod 5, which has been firmly driven into the ground, through the lug. The cone 24 at the bottom of the grounding rod 5 helps to penetrate the ground.

[0023] In this application, the structures and connections not described in detail are all prior art, and their structures and principles are well known, so they will not be described again here.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
