Description

Technical Field

[0001] This utility model relates to the technical field of busbar grounding rods, specifically multi-angle busbar grounding rods. Background Technology

[0002] Busbar grounding rod is an important grounding device used in power systems. Its main function is to safely connect power equipment to the ground, ensuring the normal operation of the equipment and the safety of personnel.

[0003] For example, Chinese Patent CN105226412B (Multifunctional Grounding Wire Insulating Rod) includes a grounding wire clamp and an insulating rod. The grounding wire clamp includes a fixed part and a movable part. The fixed part includes an upper clamping plate, which is a cavity with an open bottom surface and an arc-shaped notch in its middle. A longitudinal support rod and a movable rod are installed inside the cavity. An elastic conductor is placed between the support rod and the movable rod. The middle part of the elastic conductor is located in the arc-shaped notch. At least three fixing rings are evenly spaced along the arc length of the elastic conductor. The upper side of the fixing rings is connected to the lower end of a tension spring, and the upper end of the tension spring is fixed to the upper clamping plate along the radial direction of the arc-shaped notch. The elastic conductor is composed of multiple parallel conductive copper wires. One end of the conductive copper wire is fixed to the support rod, and the other end is fixed to the movable rod and can be wound around the outer circumference of the movable rod. This invention has a wide range of applications, is easy to use, and the grounding wire clamp has good clamping force on the charged body, ensuring a firm contact and the safety of the user.

[0004] However, most existing multi-angle busbar grounding rods rely on a single rod for handling, which can easily cause hand injuries when used in confined spaces, resulting in low safety. Furthermore, the handling method is limited, lacking flexibility and applicability. Therefore, they do not meet current needs. In response, we have proposed the multi-angle busbar grounding rod. Utility Model Content

[0005] The purpose of this utility model is to provide a multi-angle busbar grounding rod to solve the problems mentioned in the background art, which are that most of the existing multi-angle busbar grounding rods rely on a single rod for picking up, which can easily cause hand damage when used in a confined space, resulting in low safety, and the picking method is singular, with poor flexibility and applicability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle busbar grounding rod, comprising: a rod, a clamp assembly at the top of the rod, an insulating sleeve on the outside of the rod, a protective assembly on one side of the insulating sleeve, the protective assembly comprising a protective plate and a connecting frame, the connecting frame being located at both ends of the protective plate, one end of the connecting frame being provided with an embedded groove, and the connecting frame being fitted over the outside of the insulating sleeve through the embedded groove and rotating along the insulating sleeve.

[0007] Preferably, a ball bearing is embedded inside the recessed groove, and the inner wall of the ball bearing is in close contact with the outer wall of the insulating sleeve.

[0008] Preferably, the outer wall of the rod near the bottom end is provided with an external thread, a positioning sleeve is provided on the outer side of the rod near the bottom end, the inner wall of the positioning sleeve is provided with an internal thread, and the positioning sleeve is threadedly connected to the external thread through the internal thread, and a limit ring seat is provided on the top surface of the insulating sleeve.

[0009] Preferably, the clamp assembly includes an adjusting frame and an upper clamping plate, with the upper clamping plate located inside the adjusting frame. A lower clamping plate is provided at the lower end of the upper clamping plate, and the lower clamping plate moves up and down along the upper clamping plate.

[0010] Preferably, one end of the adjusting frame is provided with a connecting shaft, and one end of the connecting shaft passes through the adjusting frame and the upper clamping plate, and the upper clamping plate rotates along the connecting shaft, and the protruding end of the connecting shaft is threadedly connected to a locking nut.

[0011] Preferably, the upper end of the upper clamping plate is provided with a terminal block, and there are multiple terminal blocks, and the terminal blocks are threadedly connected to the upper clamping plate.

[0012] Preferably, the insulating sleeve, protective plate, connecting frame, and positioning sleeve are all made of rubber.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model sets a protective component on the outside of the insulating sleeve. The protective component rotates along the insulating sleeve. The worker can hold the insulating sleeve and move the whole thing. The protective plate protects the back of the worker's hand and avoids injury to the back of the hand when using it in a confined space. This improves the safety and protection of the worker. In addition, by holding the protective plate, the rotation of the protective component and the insulating sleeve can prevent the clamp component from getting tangled with the wire when adjusting the angle of the protective component. This improves the convenience and stability of picking up the grounding rod. This makes it more convenient to use the busbar grounding rod. It solves the problem that most of the existing multi-angle busbar grounding rods rely on a single rod for picking up. When used in a confined space, they are easy to cause hand injury, have low safety, and have a single picking method with poor flexibility and applicability.

[0015] (2) By setting a positioning sleeve on the outside of the bottom end of the rod, the protective component is put on the outside of the insulating sleeve. Then the positioning sleeve is connected to the external thread through the internal thread. The positioning sleeve and the limiting ring seat limit the protective component to prevent it from falling off, improve stability, and facilitate quick disassembly and installation of the protective component, thus improving flexibility.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4This utility model provides an embodiment of a multi-angle busbar grounding rod, comprising: a rod 1, a clamp assembly 3 at the top of the rod 1, an insulating sleeve 2 on the outside of the rod 1, a protective assembly 9 on one side of the insulating sleeve 2, the protective assembly 9 including a protective plate 15 and a connecting frame 16, the connecting frame 16 being located at both ends of the protective plate 15, one end of the connecting frame 16 having an embedded groove 17, the connecting frame 16 being fitted over the outside of the insulating sleeve 2 through the embedded groove 17 and rotating along the insulating sleeve 2, the clamp assembly 3 including an adjusting frame 4 and an upper clamping plate 5, the upper clamping plate 5 being located inside the adjusting frame 4, a lower clamping plate 6 being provided at the lower end of the upper clamping plate 5, the lower clamping plate 6 moving up and down along the upper clamping plate 5, a connecting shaft 8 being provided at one end of the adjusting frame 4, one end of the connecting shaft 8 passing through the adjusting frame 4 and the upper clamping plate 5, the upper clamping plate 5 rotating along the connecting shaft 8, the protruding end of the connecting shaft 8 being threadedly connected to a locking nut 11, and a terminal block 7 being provided at the upper end of the upper clamping plate 5, and the terminal block 7 being provided with... There are multiple terminals 7 and the upper clamping plate 5 are threaded together. The inner groove 17 is embedded with a ball bearing 18, and the inner wall of the ball bearing 18 is in close contact with the outer wall of the insulating sleeve 2. The ball bearing 18 improves the stability and flexibility of the rotation of the protective plate 15. When using the busbar grounding rod, the wire is connected through the terminal 7, and then the lower clamping plate 6 moves up and down along the upper clamping plate 5 to form a busbar clamping space. This is existing technology and will not be described in detail. The worker can hold the insulating sleeve 2 and move the whole thing. The protective plate 15 protects the back of the worker's hand and prevents injury to the back of the hand when using it in a confined space, thus improving the safety and protection of the worker. Furthermore, by holding the protective plate 15, the protective component 9 and the insulating sleeve 2 rotate, preventing the clamping component 3 from getting tangled with the wire when adjusting the angle of the protective component 9, thus improving the convenience and stability of picking up the wire. This makes it more convenient to use the busbar grounding rod.

[0023] When the angle of the clamp assembly 3 needs to be adjusted, loosen the locking nut 11. Since one end of the connecting shaft 8 passes through the adjusting frame 4 and the upper clamping plate 5, the upper clamping plate 5 rotates along the connecting shaft 8 to adjust the angle. It has flexible and changeable installation angle characteristics, which can adapt to complex electrical equipment layout and space constraints, improve flexibility and applicability. After adjusting the angle, tighten the locking nut 11 to squeeze and lock the clamp assembly 3.

[0024] The outer wall of the rod 1 near the bottom end is provided with an external thread 12, and a positioning sleeve 10 is provided on the outer side of the rod 1 near the bottom end. The inner wall of the positioning sleeve 10 is provided with an internal thread 13, and the positioning sleeve 10 is threadedly connected to the external thread 12 through the internal thread 13. The top surface of the insulating sleeve 2 is provided with a limit ring seat 14. The protective component 9 is fitted on the outside of the insulating sleeve 2. At this time, the inner wall of the ball bearing 18 is in close contact with the outer wall of the insulating sleeve 2. Then, the positioning sleeve 10 is threadedly connected to the external thread 12 through the internal thread 13. The positioning sleeve 10 and the limit ring seat 14 limit the protective component 9 to prevent it from falling and improve stability. Since the insulating sleeve 2, the protective plate 15, the connecting frame 16 and the positioning sleeve 10 are all made of rubber material, electric shock is avoided and safety is improved.
