Description

Technical Field

[0001] This utility model relates to the field of grounding wire technology, and in particular to a grounding wire with a warning device. Background Technology

[0002] Grounding wires are critical devices for ensuring electrical safety. They consist of a conductor, equipment clamps (such as alligator clips), and a grounding terminal (connected to a grounding rod / ground bar / metal pole). By reliably connecting the metal casing of electrical equipment to the earth, leakage current or static current is directly conducted into the ground, preventing electric shock to personnel and damage to equipment. They are commonly used in power maintenance and temporary power supply at construction sites, and are a fundamental protective measure against electric shock accidents.

[0003] In scenarios without a fixed grounding system, such as outdoor power maintenance and temporary power supply at construction sites, portable grounding wires (consisting of a conductor, end clamps, and a grounding rod) are typically inserted into the soil to achieve temporary grounding protection. However, because these three parts are rather scattered, they are not only inconvenient to store and time-consuming to organize, but also prone to scratches and bumps during transport. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to provide a grounding wire with a warning device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A grounding wire with a warning device includes a grounding rod, a conductor, and an end clamp. A horizontally arranged reel is fixedly connected to the upper end of the grounding rod. An annular storage groove is provided on the outer wall of the reel. The conductor is wound around the inner wall of the storage groove, with one end of the conductor passing through the reel and fixedly connected to the upper end of the grounding rod. The end clamp is fixedly connected to the end of the conductor away from the grounding rod. A connecting piece is fixedly connected to the bottom inner wall of the storage groove. The end of the end clamp away from the conductor is held in place by the connecting piece. A connecting block is fixedly connected to the upper end of the reel, near its left edge. The upper end of the connecting block has a storage groove. The upper end of the reel is provided with a horizontally arranged connecting plate. Warning signs are fixedly connected to both the upper and lower sides of the connecting plate. The left end of the connecting plate extends into the storage groove and is fixedly connected to a vertically arranged connecting post. A vertically arranged connecting rod is fixedly inserted into the connecting post.

[0014] 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.

[0015] Reference Figure 1-3A grounding wire with a warning device includes a grounding rod 2, a conductor 3, and an end clamp 4, used to form a grounding wire to achieve grounding operation. A fixing ring 5 is fixedly sleeved on the upper end of the grounding rod 2 to improve the firmness between the grounding rod 2 and the winding reel 1. The upper end of the fixing ring 5 is fixedly connected to the lower end of the winding reel 1. A horizontally arranged winding reel 1 is fixedly connected to the upper end of the grounding rod 2 to cooperate with the storage groove to store the conductor 3. The material of the winding reel 1 is polyimide to ensure strength and provide insulation. A ring-shaped storage groove is provided on the outer side wall of the winding reel 1. A rubber pad 7 is fixedly connected to the inner side wall of the storage groove to prevent the conductor 3 from abrading the inner wall of the storage groove. The conductor 3 is wound around the inner wall of the storage groove. One end of the conductor 3 passes through the winding reel 1 and is fixedly connected to the upper end of the grounding rod 1. The end clamp 4 is fixedly connected to the end of the conductor 3 away from the grounding rod 2. A connecting piece 6 is fixedly connected to the inner bottom of the storage groove to connect the end clamp 4. The end of the end clamp 4 away from the conductor 3 is clamped on the connecting piece 6. In this embodiment, a connecting block 8 is fixedly connected to the upper end of the cable reel 1 near the left edge for mounting the connecting rod 14. The upper end of the connecting block 8 is provided with a storage groove. The upper end of the cable reel 1 is provided with a horizontally arranged connecting plate 10 for mounting the warning sign 11. A U-shaped handle 12 is fixedly connected to the upper side wall of the connecting plate 10 for easy lifting of the connecting plate 10 by the user. A rubber sleeve is fixedly fitted to the upper end of the handle 12 to improve the grip. A rubber block 13 is fixedly connected to the lower end of the connecting plate 10 near the right edge to prevent the lower end of the connecting plate 10 from colliding with the upper end of the cable reel 1. Warning signs 11 are fixedly connected to both the upper and lower sides of the connecting plate 10 for safety warning purposes. In this embodiment, the left end of the connecting plate 10 extends into the storage groove and is fixedly connected to a longitudinally arranged connecting post 15 for supporting the connecting plate 10. A longitudinally arranged connecting rod 14 is fixedly inserted into the connecting post 15 for supporting the connecting post 15. The front and rear ends of the connecting rod 14 pass through the connecting post 15 and are rotatably connected to the inner sidewall of the storage groove.

[0016] In this embodiment, the connecting plate 10 is first pressed down to move the reel 1 and the grounding rod 2 downwards, so that the grounding rod 2 is inserted into the ground. Then, the end clip 4 is removed, and the wire 3 is taken out from the storage groove. The end clip 4 is then clamped onto the conductive parts such as the metal shell and frame of the grounded equipment to complete the grounding operation. In addition, the locking screw 9 is unscrewed, and the connecting plate 10 is manually rotated and lifted to make it vertical. The warning signs 11 on both sides of the connecting plate 10 play a safety warning role and enhance the safety of use. Finally, the locking screw 9 is screwed into the slot to prevent the support 15 from loosening, thereby preventing the connecting plate 10 from loosening. When storing, the wire 3 is wound into the annular storage groove of the reel 1. The storage groove structure is used to realize the winding and storage of the wire 3. Then, the end clip 4 is clamped on the connecting piece 6 to prevent it from loosening. Finally, the connecting plate 10 is reset, thereby improving the portability.
