Description

Technical Field

[0001] This utility model relates to the field of direct lightning protection technology, and in particular to a small lightning suppression device. Background Technology

[0002] Currently, both domestic and international approaches to direct lightning strike protection rely on the "lightning-to-ground" theory invented by American scientist Benjamin Franklin in 1752. This involves designing and installing lightning protection devices based on the shape, type, and usage of the protected object, attracting the lightning current to the device and guiding it to the ground to protect the object. However, this method still poses risks such as backflashover, step voltage, contact voltage, lightning impulse induced overvoltage, and secondary electromagnetic radiation. In particular, the surge sources released during lightning strikes can damage electronic equipment within buildings.

[0003] Furthermore, non-"lightning-to-ground" lightning protection technologies have continued to develop, resulting in various "lightning-blocking, lightning-rejecting, lightning-resisting, and lightning-suppressing" devices. These devices are mostly based on the theory of "ionizing air and neutralizing thundercloud charges." When the spatial electric field changes during the development of a thundercloud, the probe attracts the thundercloud charge, generating a high-intensity electric field between the upper and lower electrodes. This ionizes the air between the upper and lower electrodes, producing a large number of positive and negative ions. These positive and negative ions diffuse outward and rapidly drift and conduct towards the area of ​​strong charge accumulation at the bottom of the thundercloud and the area of ​​strong opposite charge accumulation induced on the ground, respectively, and neutralize the charge. This cuts off the lightning path, reduces the spatial potential, blocks the development of the lightning path, and prevents lightning strikes. However, these devices are generally large in size and weight, and have low ionization efficiency. Further improvements are needed to miniaturize and lighten the devices and improve air ionization efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing lightning protection equipment is too large, too heavy and has low ionization efficiency, so it cannot be applied to small or independent buildings and equipment.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a small lightning suppression device, comprising a base and an equipotential body, wherein a support column is fixedly connected to the top outer wall of the base, a slot is provided on the inner wall of the support column, a connector is inserted into the slot, and four first threaded holes are provided on the top outer wall of the connector.

[0006] The inner wall of the equipotential body has four second threaded holes, which are threadedly connected to the first threaded holes. The outer wall of the top of the equipotential body has four third threaded holes, which are circumferentially distributed and symmetrically positioned. The inner wall of the third threaded holes is threadedly connected to the side-drawing needle.

[0007] As a preferred embodiment of the small lightning suppression device of this utility model, the base has mounting holes on its bottom outer wall.

[0008] In a preferred embodiment of the small lightning suppression device described in this utility model, the connecting body is made of insulating material.

[0009] As a preferred embodiment of the small lightning suppression device described in this utility model, the upper end of the equipotential body is a solid hemisphere, and the lower end is a hollow cylindrical sleeve.

[0010] As a preferred embodiment of the small lightning suppression device of this utility model, the top outer wall of the equipotential body is provided with a fourth threaded hole, which is located in the middle of the four third threaded holes.

[0011] In a preferred embodiment of the small lightning suppression device described in this utility model, the fourth threaded hole is threadedly connected to the top-pull pin.

[0012] As a preferred embodiment of the small lightning suppression device described in this utility model, the side-drawing needle is 160mm long.

[0013] As a preferred embodiment of the small lightning suppression device described in this utility model, the top attracting needle is 100mm long.

[0014] The beneficial effects of this utility model are as follows: This utility model attracts and conducts the charge at the bottom of the thundercloud to the equipotential body through the side-attracting and top-attracting needles. Since the equipotential body and the support column on the base are connected by a connecting body made of insulating material, and the base is connected to the ground wire through the mounting hole, as the amount of charge accumulates, a significant potential difference will exist between the equipotential body sleeve and the support column on the base, thereby forming a discharge space, ionizing the air and generating charged ions. The equipotential body sleeve is the upper electrode, and the support column on the base is the lower electrode. Due to the special structural design, the amount of charge accumulated is large and the speed is fast, which can significantly improve the efficiency of air ionization, generate more charged ions, and more effectively suppress direct lightning strikes in the protected area. Due to the small size and light weight of the equipment, it can effectively achieve lightning protection and is suitable for various small buildings and independent equipment. Through the miniaturized and lightweight design, the lightning protection is more flexible and efficient, providing a reliable lightning protection solution for small buildings and independent equipment.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Example

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 8 This embodiment provides a small lightning suppression device, including a base 1 and an equipotential body 3. A support column 2 is fixedly connected to the top outer wall of the base 1. A slot 201 is opened on the inner wall of the support column 2. The slot 201 is inserted into the connector 202. The top outer wall of the connector 202 is provided with four first threaded holes 203.

[0027] The inner wall of the equipotential body 3 has four second threaded holes 301, which are threaded to the first threaded hole 203. The outer wall of the top of the equipotential body 3 has four third threaded holes 302, which are circumferentially distributed and symmetrically positioned. The inner wall of the third threaded hole 302 is threaded to the side-gathering needle 4.

[0028] Specifically, in this embodiment, the side-attracting needle 4 and the top-attracting needle 5 are connected to the equipotential body 3 through the third threaded hole 202 and the fourth threaded hole 303, respectively. The upper end of the equipotential body 3 is a solid hemisphere, and the lower end is a hollow cylindrical sleeve. The equipotential body 3 is connected to the support column 2 on the base 1 through the connecting body 202. The side-attracting needle 4 and the top-attracting needle 5 attract and conduct the charge at the bottom of the thundercloud to the equipotential body 3. Since the equipotential body 3 and the support column 2 on the base 1 are connected by the connecting body 202, the connecting body 202 is made of insulation. Made of materials, the base 1 is connected to the ground wire through the mounting hole 101. As the amount of charge accumulates, there will be a significant potential difference between the equipotential body 3 sleeve and the base support column 2, thus forming a discharge space, ionizing the air to generate charged ions. The equipotential body 3 sleeve is the upper electrode, and the support column on the base 1 is the lower electrode. Due to the special structural design, the amount of charge accumulated is large and the speed is fast, which can significantly improve the efficiency of air ionization, generate more charged ions, and more effectively suppress direct lightning strikes in the protected area.

[0029] Reference Figures 4-8 The base 1 has an installation hole 101 on its bottom outer wall. The connector 202 is made of insulating material. The upper end of the equipotential body 3 is a solid hemisphere and the lower end is a hollow cylindrical sleeve. The top outer wall of the equipotential body 3 has a fourth threaded hole 303. The fourth threaded hole 303 is located in the middle of the four third threaded holes 302. The fourth threaded hole 303 is threaded to the top lead-gathering pin 5. The side lead-gathering pin 4 is 160mm long and the top lead-gathering pin 5 is 100mm long.

[0030] Specifically, in this embodiment, if independent towers equipped with surveillance cameras are used on both sides of the road, lightning rods may be used for lightning protection. However, during lightning strikes, lightning surge currents may occur, causing overvoltage and damaging the surveillance equipment. Existing "non-grounding" lightning protection devices are generally large and heavy, and are inconvenient to install on towers due to load-bearing capacity and space occupation. They are not suitable for lightning protection of small independent objects or independent towers. The small and lightweight lightning suppression device provided by this utility model can perfectly solve this problem. It is compact, lightweight, and highly efficient, and is suitable for lightning protection of various small or independent buildings and equipment.

[0031] Working principle: The side-attracting needle 4 and the top-attracting needle 5 are connected to the equipotential body 3 through the third threaded hole 202 and the fourth threaded hole 303, respectively. The upper end of the equipotential body 3 is a solid hemisphere, and the lower end is a hollow cylindrical sleeve. The equipotential body 3 is connected to the support column 2 on the base 1 through the connector 202. The side-attracting needle 4 and the top-attracting needle 5 attract and conduct the charge at the bottom of the thundercloud to the equipotential body 3. Since the equipotential body 3 and the support column 2 on the base 1 are connected by the connector 202, which is made of insulating material, the base 1 is connected to the ground wire through the mounting hole 101. As the amount of charge accumulates, a significant potential difference will exist between the sleeve of the equipotential body 3 and the support column 2 of the base, thus forming a discharge space, ionizing the air and generating charged ions. The sleeve of the equipotential body 3 is the upper electrode. The support column 1 on the base is the lower electrode. Due to its special structural design, it accumulates a large number of charges at a fast speed, which can significantly improve the efficiency of air ionization, generate more charged ions, and more effectively suppress direct lightning strikes within the protected area. If there are independent towers with monitoring camera equipment on both sides of the road, using lightning rods for lightning protection may result in lightning surge currents during lightning strikes, causing overvoltage damage to the monitoring equipment. Existing "non-lightning-to-ground" lightning protection devices are generally large and heavy, and are inconvenient to install on towers due to load-bearing and space occupation. They are not suitable for lightning protection of small independent objects or independent towers. The small and lightweight lightning suppression device provided by this utility model can perfectly solve this problem. It is compact, lightweight, and highly efficient, and is suitable for lightning protection of various small or independent buildings and equipment.
