Description

Technical Field

[0001] This utility model belongs to the field of lightning protection technology, specifically a shovel-type lightning protection grounding electrode. Background Technology

[0002] The shovel-type lightning protection grounding electrode is a grounding device commonly used in lightning protection grounding systems. It has a large contact area and good conductivity, which can effectively conduct lightning current into the ground through the grounding electrode to reduce grounding resistance, thereby improving the lightning protection effect. It performs outstandingly in occasions that require a large grounding area and low grounding resistance.

[0003] Existing shovel-type lightning protection systems typically use directly inserted grounding electrodes. Most operations rely on manual sledgehammering or mechanical hammering to drive them into the ground. This method is labor-intensive, inefficient, and requires specific site conditions and space for machinery operation. It is also difficult to work in hard soil or gravel layers, making it impossible to reach the preset depth and resulting in substandard grounding resistance. Furthermore, the grounding electrodes are mostly fixed structures, making storage and transportation inconvenient. Traditional grounding electrodes are often designed with a sharp point at one end to facilitate driving, further hindering transport. Another fundamental limitation of traditional directly inserted grounding electrodes is the limited contact area with the soil during installation. This is because, during driving, especially in cohesive soils, the hammering violently compresses and disturbs the soil, causing the soil around the grounding electrode to become denser, creating voids and increasing contact resistance, leading to poor grounding resistance stability. Therefore, improvements are needed. Summary of the Invention

[0004] This invention provides a shovel-type lightning protection grounding electrode, solving the problems of inconvenience during storage and transportation, limited contact area with soil during installation, and poor stability of grounding resistance. To achieve the above objectives, this utility model provides the following technical solution: a shovel-type lightning protection grounding electrode, comprising a shell-shaped column, a movable component movably connected to the inner cavity of the shell-shaped column, a connecting component provided at the lower end of the shell-shaped column, a soil-breaking rod fixedly installed at the bottom of the movable component, the connecting component comprising a shovel-shaped wing, a connecting rod hinged to the upper end of the inner side of the shovel-shaped wing, a movable rod hinged to the middle of one side of the connecting rod, the end of the movable rod away from the connecting rod hinged to the movable component, and the lower end of the shell-shaped column hinged to the upper end of the shovel-shaped wing.

[0005] Preferably, the moving component includes a moving main rod, with moving rods movably connected to both sides of the moving main rod, and the lower end of the moving rods movably connected to the shell-shaped column.

[0006] Preferably, the outer wall of the moving rod is threaded and threadedly connected to the moving main rod and the shell-shaped column, and the upper end of the moving rod is provided with a grip plate.

[0007] Preferably, a groove is provided at the lower end of the inner cavity of the shell-shaped column, and a slider is provided on the outer wall of the soil-breaking rod, and the shell-shaped column and the soil-breaking rod are movably connected.

[0008] Preferably, the lower end of the soil-breaking rod is tapered, and the top of the soil-breaking rod is fixedly connected to the bottom of the movable main rod.

[0009] Preferably, the lower end of the connecting rod is hinged to the shell-shaped column, and the shell-shaped column and the moving main rod are provided with fixing ears at both ends.

[0010] Preferably, both the shell-shaped column and the moving component are made of copper-clad steel, and the inner diameter of the shell-shaped column is larger than the outer diameter of the moving main rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: Through the cooperation of structures such as the moving component and the connecting component, the connecting rod rotates when the moving rod moves downward. The rotating connecting rod abuts against the shovel-shaped wing, causing the shovel-shaped wing to flip. The flipping of the shovel-shaped wing increases the contact area with the ground. After moving a certain distance, the moving main rod drives the soil-breaking rod to gradually move downward when it moves downward. The tip of the soil-breaking rod will not be exposed, making it more convenient for storage and transportation. It also achieves the goal of increasing the contact area with the soil during installation, resulting in better stability of the grounding resistance. Attached Figure Description

[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. 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.

[0016] like Figures 1 to 4 As shown, this utility model provides a shovel-type lightning protection grounding electrode, including a shell-shaped column 1, a movable component 2 movably connected to the inner cavity of the shell-shaped column 1, and a connecting component 3 provided at the lower end of the shell-shaped column 1.

[0017] Among them, the bottom of the mobile component 2 is fixedly installed with a soil-breaking rod 4.

[0018] The connecting component 3 includes a shovel-shaped wing 31, a connecting rod 32 is hinged to the upper end of the inner side of the shovel-shaped wing 31, a movable rod 33 is hinged to the middle of one side of the connecting rod 32, the end of the movable rod 33 away from the connecting rod 32 is hinged to the moving component 2, and the lower end of the shell-shaped column 1 is hinged to the upper end of the shovel-shaped wing 31.

[0019] The movable component 2 includes a movable main rod 21, with movable rods 22 movably connected to both sides of the movable main rod 21. The lower end of the movable rods 22 is threadedly connected to the shell-shaped column 1.

[0020] Using the above scheme: Through the cooperation of the moving component 2 and the connecting component 3, when it is necessary to install the shovel-type lightning protection grounding electrode, the bottom of the moving main rod 21 is fixed in contact with the ground. Then, the moving rod 22 is rotated, which drives the moving main rod 21, the breaking rod 4, and the movable rod 33 to move downwards. When the movable rod 33 moves downwards, the connecting rod 32 rotates. The rotation of the connecting rod 32 abuts against the shovel-shaped wing 31, causing the shovel-shaped wing 31 to flip. The flipping of the shovel-shaped wing 31 increases the contact area with the ground. After moving a certain distance, the shovel-shaped wing 31 is fully opened, and the moving main rod 2... 1. When moving downwards, the soil-breaking rod 4 gradually moves downwards and drills into the soil, thus fixing the lightning protection grounding body. At the same time, the cooperation of the shovel-shaped wing 31 increases the contact area with the ground, which can effectively reduce the grounding resistance, disperse the lightning current, improve the system stability, and enhance the adaptability to different soil conditions and lightning strike intensities. When not in use, the soil-breaking rod 4 is located in the inner cavity of the shell-shaped column 1, and the tip of the soil-breaking rod 4 will not be exposed, making it more convenient for storage and transportation. It also achieves the goal of increasing the contact area with the soil during installation, resulting in better stability of the grounding resistance.

[0021] like Figure 3 , Figure 4As shown, the outer wall of the moving rod 22 is threaded and is threadedly connected to the moving main rod 21 and the shell-shaped column 1. The upper end of the moving rod 22 is provided with a grip plate, and the lower end of the connecting rod 32 is hinged to the shell-shaped column 1. The shell-shaped column 1 and the moving main rod 21 are provided with fixing ears at both ends. The shell-shaped column 1 and the moving assembly 2 are both made of copper-clad steel. The inner diameter of the shell-shaped column 1 is larger than the outer diameter of the moving main rod 21.

[0022] The above scheme is adopted: through the cooperation of the moving rod 22 and the main moving rod 21, and the design of the thread on the outer wall of the moving rod 22, when the moving rod 22 is rotated, due to the threaded cooperation between the moving rod 22 and the shell-shaped column 1 and the constraint at its lower end, the rotational motion of the moving rod 22 is converted into the downward linear motion of the main moving rod 21. The design of the handle at the upper end of the moving rod 22 makes it easier to rotate. The connecting rod 32 is hinged to the shell-shaped column 1, so that when the main moving rod 21 drives the movable rod 33 to move downward, the connecting rod 32 will flip, thereby causing the shovel-shaped wing 31 to... The design of the fixed ears at both ends of the shell-shaped column 1 and the movable main rod 21 makes it more convenient to move or install the lightning protection grounding body. Due to the material limitations of the shell-shaped column 1 and the movable component 2, the copper-clad steel material has a significant improvement in the conductivity of the grounding system, thereby enhancing the discharge capacity of lightning current, protecting the equipment from lightning strikes, maintaining a long service life, reducing maintenance frequency, and resisting greater tensile force and soil deformation, reducing the risk of breakage. The design of the inner diameter of the shell-shaped column 1 being larger than the outer diameter of the movable main rod 21 allows the movable main rod 21 to move within the cavity of the shell-shaped column 1.

[0023] like Figure 2 , Figure 4 As shown, a groove is provided at the lower end of the inner cavity of the shell-shaped column 1, and a slider is provided on the outer wall of the soil-breaking rod 4. The shell-shaped column 1 and the soil-breaking rod 4 are movably connected. The lower end of the soil-breaking rod 4 is tapered, and the top of the soil-breaking rod 4 is fixedly connected to the bottom of the moving main rod 21. The soil-breaking rod 4 is fixedly connected to the moving main rod 21, and the moving main rod 21 moves within the shell-shaped column 1. Therefore, the slider on the soil-breaking rod 4 and the groove on the shell-shaped column 1 constitute a guiding mechanism, which prevents the soil-breaking rod 4 and the moving main rod 21 assembly from rotating during descent, ensuring that they only perform linear motion.

[0024] The above scheme employs the following: through the cooperation of the shell-shaped column 1 and the ground-breaking rod 4, and the design of the sliding groove of the shell-shaped column 1 and the slider of the ground-breaking rod 4, the shell-shaped column 1 limits the ground-breaking rod 4 during movement, making the ground-breaking rod 4 more stable during movement. The tapered design at the lower end of the ground-breaking rod 4 provides better stability and adaptability in different types of soil, making the installation process simpler and faster, allowing it to be more stably embedded in the soil, providing strong tensile strength, reducing the displacement or loosening of the grounding electrode under external forces, and ensuring long-term stable grounding performance. The ground-breaking rod 4 and the moving main rod 21 are fixedly connected, so that the movement of the moving main rod 21 drives the movement of the ground-breaking rod 4, embedding the ground-breaking rod 4 into the soil, thereby fixing and installing the lightning protection grounding electrode.

[0025] The initial state of this utility model is as follows: the shovel-shaped wing 31 is retracted and closely attached to the shell-shaped column 1, the soil-breaking rod 4 is retracted into the inner cavity of the shell-shaped column 1, and the entire grounding body forms a compact columnar structure.

[0026] The specific working process of this utility model is as follows: Step S1: The operator rotates the grip at the upper end of the moving rod 22. Since the moving rod 22 is connected to the shell-shaped column 1 by a thread, the rotational motion is converted into the linear downward motion of the moving main rod 21.

[0027] Step S2: The main moving rod 21 moves downward, causing the soil breaking rod 4 at its bottom to move downward as well. The conical head at the lower end of the soil breaking rod 4 begins to cut into the soil. At the same time, the slider on the soil breaking rod 4 slides along the groove on the inner wall of the shell-shaped column 1, ensuring that the entire moving assembly moves downward in a straight line without rotating.

[0028] Step S3: When the main moving rod 21 moves downward, it will push the movable rod 33, which is hinged to it, to move downward together. The downward linear movement of the movable rod 33 will generate a downward pulling force on the connecting rod 32.

[0029] Step S4: At this time, the connecting rod 32 is a lever with the fulcrum being the part where the lower end is hinged to the shell-shaped column 1, the middle part is hinged to the movable rod 33 and subjected to a downward force, and its upper end is hinged to the inner side of the shovel-shaped wing 31. According to the lever principle, when the force point of the movable rod 33 is pulled downward, the connecting rod 32 will rotate outward around the fulcrum at its lower end.

[0030] Step S5: As the upper end of the connecting rod 32 rotates outward, it pushes the shovel-shaped wing 31 that is hinged to it, forcing the shovel-shaped wing 31 to flip outward and downward around its hinge point with the upper end of the shell-shaped column 1.

[0031] Step S6: As the main moving rod 21 continues to move downwards, the movable rod 33 continues to pull down, and the connecting rod 32 continues to rotate until the shovel-shaped wing 31 is fully deployed, forming a shovel-shaped wing surface in contact with the soil. At this point, the soil resistance and the force inside the mechanism reach equilibrium, the grounding electrode is firmly installed in the ground, and the maximum contact area is achieved.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
