Description

Technical Field

[0001] This utility model relates to the field of power maintenance tools, specifically a portable grounding hammer. Background Technology

[0002] A grounding rod is a power device used for grounding protection. Grounding rods are mainly used in power systems for grounding operations. By guiding the current in the system to the ground, they achieve safe current dispersion and voltage control, ensuring personal safety and the normal operation of equipment. A grounding rod is typically a long, rod-shaped conductor made of conductive material, with one end connected to the power system and the other end in contact with the ground. In existing designs, grounding rods require workers to use a hammer to drive them into the ground. This is difficult in dry, hard, sticky, or frozen soil, often resulting in insufficient burial depth and inadequate grounding resistance, increasing operational safety risks. Furthermore, when removing grounding rods, because the burial depth exceeds 0.6m, they are difficult to pull out, and when they cannot be pulled out, they must be discarded, resulting in waste.

[0003] For example, the portable safety grounding rod with patent publication number CN204189972U includes a rod body in the shape of a T, with a pointed bottom end. A sleeve is fitted over the pointed end, and a strap is provided at the upper end of the sleeve to connect to the upper end of the rod body. Using the portable safety grounding rod described in this invention, the T-shaped rod body increases the contact area of ​​the striking part at the top of the grounding rod, strengthens the force point, concentrates the force, improves work efficiency, and enhances worker safety; the sleeve at the pointed end prevents injury; and the strap makes it easy to carry.

[0004] A manual impact-type grounding rod device, such as the one disclosed in patent publication number CN216488553U, includes a striking rod, a striking hammer, a limiting nut, a connecting nut, a grounding rod, and a grounding wire connecting plate. The striking rod and the grounding rod are connected by the connecting nut, and the connecting nut and the grounding rod are positioned by a pin. The limiting nut is installed on the upper part of the striking rod, and the striking hammer is slidably connected to the striking rod between the limiting nut and the connecting nut. The grounding wire connecting plate is fixed to the grounding rod, and the bottom end of the grounding rod is a pointed tip. This utility model facilitates the embedding of the grounding rod and makes it easy to extract. The striking rod and the grounding rod are separate structures, and the striking rod can be used for the installation of multiple grounding rods. The burial depth marking line makes it easy to identify the burial depth. The installation of the grounding wire is time-saving, labor-saving, and material-saving. It is convenient for outdoor use in winter, low-cost, convenient, and practical, and can significantly reduce the risk of unreliable grounding.

[0005] However, during the use of the above-mentioned and similar equipment, due to the structure of connecting the upper and lower parts of the sleeve rod with the hammer block, the structure is not reliable enough under the action of impact force. The sleeve rod and the pin are easily deformed and not durable under the action of impact force, and the large size of the hammer block hinders the operator from grasping and applying force. When the grounding rod is driven into the ground under force, it is easy to bend and become unstable, and it is also not easy to pull it out, which affects the work efficiency. Therefore, in view of this situation, we propose a more convenient and practical grounding rod that meets the usage requirements. Utility Model Content

[0006] The purpose of this invention is to provide a convenient floating grounding rod to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a convenient movable grounding rod, comprising a grounding electrode, a vibration mechanism, a movable grounding body, and a sliding rod. The vibration mechanism includes a first vibration block and a second vibration block. The grounding electrode, the first vibration block, the second vibration block, and the sliding rod are firmly connected by welding. The movable grounding body is fitted onto the sliding rod with a clearance fit. The movable grounding body is a solid metal cylinder.

[0008] Furthermore, the grounding electrode, the first shock block, the second shock block, and the sliding rod are firmly connected by welding, and the lower end of the second shock block is fixedly connected to the grounding electrode.

[0009] Furthermore, there is a nut between the second shock block and the grounding electrode. One side of the nut is welded to the second shock block, and the other side is welded to the grounding electrode.

[0010] Furthermore, the main body of the swing hammer is a solid steel metal cylinder, sphere, or rugby ball with a through hole in the center and anti-slip patterns and textures on the surface.

[0011] Furthermore, the diameter of the through hole in the movable hammer body is larger than that of the slide rod, and it is in clearance fit with the movable hammer body, with a clearance of 0.2-0.5mm. The movable hammer body can slide freely up and down on the slide rod without resistance.

[0012] Furthermore, the grounding electrode is equipped with a handle on the radial side near the shock mechanism, and the handle is vertically fixed to the outer wall of the grounding electrode.

[0013] Furthermore, the upper part of the grounding electrode, near the shock mechanism, has at least one wiring hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This portable grounding bar with a sliding hammer has a sturdy structure. The second impact block is welded to the grounding electrode with a nut to increase the connection strength and make the grounding bar strong and durable. The sliding hammer is a solid steel body with a certain weight, which increases the impact force. The surface of the column has anti-slip texture, which makes it easy for operators to grasp and apply force, and can quickly save working time.

[0016] It also facilitates personnel support and solves the problem of grounding rods easily tilting when subjected to impact loads. During the pulling process, the moving weight applies force to the first impact block. When the grounding rod becomes loose, the handle can be gripped and upward force applied, making it easier to pull out the grounding rod. Furthermore, the wiring hole is directly located on the grounding electrode, resulting in a simple structure and saving materials. Attached Figure Description

[0022] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] During power maintenance, grounding rods are required. The grounding rod provided by this utility model is specifically designed for power maintenance. When using this equipment for power maintenance, it is necessary to ensure that the grounding rod is in good contact with the soil before operation to ensure the grounding effect. When using a vibrating hammer for vibration, the force should be moderate to avoid excessive impact that could damage the equipment or injure personnel. The integrity of the grounding rod and its accessories should be checked regularly, and any damage or wear should be replaced in time.

[0024] like Figures 1-4As shown, this utility model provides a technical solution: a convenient moving hammer grounding rod, including a grounding electrode 1, a shock mechanism 2, a moving hammer body 3 and a sliding rod 5. The shock mechanism 2 includes a first shock block 21 and a second shock block 22. The grounding electrode 1, the first shock block 21, the second shock block 22 and the sliding rod 5 are firmly connected by welding. The moving hammer body 3 is fitted onto the sliding rod 5 with a clearance fit. The moving hammer body 3 is a solid metal column.

[0025] In Example 1, the grounding electrode 1, the first shock block 21, the second shock block 22 and the slide rod 5 are firmly connected by welding. The lower end of the second shock block 22 is fixedly connected to the grounding electrode 1. There is a nut between the second shock block 22 and the grounding electrode 1. One side of the nut is welded to the second shock block 22 and the other side is welded to the grounding electrode 1.

[0026] It should be noted that when the operator lifts and releases the movable hammer body 3, the movable hammer body 3 will slide down the slide bar 5 under the action of gravity and impact the first impact block 21 of the impact mechanism 2. This impact will generate an impact force, causing the second impact block 22 of the impact mechanism 2 to exert a downward thrust on the grounding electrode 1. Since the grounding electrode 1, the first impact block 21, the second impact block 22 and the slide bar 5 are firmly connected by welding, this thrust can be stably transmitted to the grounding electrode 1, allowing it to be inserted into the soil. This effectively resists repeated impacts and wear caused by long-term use, ensuring that the grounding rod always maintains a good working condition during use. At the same time, the firm connection between the components also avoids accidents caused by unstable connections, improving operational safety.

[0027] Example 2: The movable hammer body 3 is a solid steel metal cylinder, sphere, or rugby ball with a through hole 31 in the center. The surface has anti-slip patterns and textures. The diameter of the through hole 31 of the movable hammer body 3 is larger than that of the slide rod 5, and it is in clearance fit with the movable hammer body 3. The clearance is 0.2-0.5mm, and the movable hammer body 3 can slide freely up and down on the slide rod 5 without resistance.

[0028] It is important to note that the pendulum body 3 is designed as a solid steel metal cylinder, sphere, or rugby ball. This design not only ensures the weight and strength of the pendulum body 3 but also provides it with good impact resistance. A through hole 31 is formed in the center of the pendulum body 3. The diameter of this through hole 31 is larger than the diameter of the slide rod 5, creating a clearance fit between the pendulum body 3 and the slide rod 5. The clearance is controlled between 0.2-0.5mm. This design ensures that the pendulum body 3 can slide freely up and down on the slide rod 5 without resistance, while avoiding the wobbling problem of the pendulum body 3 during sliding due to excessive clearance.

[0029] Example 3: A handle 4 is installed on the radial side of the grounding electrode 1 near the shock mechanism 2. The handle 4 is vertically fixed to the outer wall of the grounding electrode 1. There is at least one wiring hole 11 on the upper part of the grounding electrode 1 near the shock mechanism 2.

[0030] It should be noted that a handle 4 is installed on the radial side of the grounding electrode 1 near the vibration mechanism 2. This handle 4 is vertically fixed to the outer wall of the grounding electrode 1. Operators can easily carry and operate the grounding rod by holding the handle 4, greatly improving the convenience of use. At the same time, at least one wiring hole 11 is designed on the upper part of the grounding electrode 1 near the vibration mechanism 2. The wiring hole 11 is designed to connect the grounding wire, ensuring that the grounding rod can effectively conduct current into the earth, thereby achieving the purpose of grounding protection.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
