Description

Technical Field

[0001] This utility model relates to the technical field of lightning protection devices, specifically a center-mounted lightning protection grounding lightning rod for base stations. Background Technology

[0002] GNSS (Global Navigation Satellite System) is a system that uses artificial Earth satellites for positioning, navigation, and timing. It is widely used in surveying, transportation, communication, agriculture, and many other fields. The basic principle of GNSS positioning is to determine the receiver's position by measuring the distance between the receiver and multiple satellites, combining this with known satellite positions, and using three-dimensional coordinate calculation methods. Therefore, depending on the specific application scenario, such as in surveying and geographic information systems (GIS), agriculture, and geological hazard detection, GNSS fixed base stations are commonly installed on poles in the field. They play a particularly important role in geological hazard detection systems for mine tailings ponds and are widely used.

[0003] Tailings dams are crucial facilities for storing mine waste (tailings). Due to their large size and complex structure, tailings dams are prone to accidents such as landslides and tailings leaks. Geological safety monitoring of tailings dams can be effectively achieved by integrating GNSS base stations with equipment and technologies such as lidar and digital twins. However, since tailings dams are often located in exposed, open environments, placing fixed GNSS base stations nearby makes them susceptible to lightning strikes, leading to equipment damage, data loss, and even safety threats to inspection personnel. Designing a novel center-aligned lightning protection grounding device is key to ensuring the safe operation of GNSS base stations.

[0004] Referring to the lightning protection practices of installing aviation obstruction lights on rooftops in the "12YD10 Lightning Protection and Grounding Engineering" drawing set, designing an equipotential lightning protection grounding device with lights based on the existing lightning rod can improve lightning protection efficiency.

[0005] Currently, most GNSS fixed base stations installed in the field use a separate structure with separately installed lightning rods and grounding. When the lightning rod is struck by lightning, a large amount of lightning enters the grounding grid through the grounding conductor, causing a sudden rise in ground potential. The base station equipment suffers backflash damage due to the excessive potential difference. Unequal grounding systems are prone to generating high-frequency stray currents, which can lead to electromagnetic interference and signal quality degradation. Therefore, multi-stage, selective surge protection devices are often required, increasing costs. Furthermore, when the potentials of the two grounding grids are inconsistent, a person touching the metal components spanning between them can experience ground voltages as high as hundreds or even thousands of volts, posing a serious risk of electric shock.

[0006] Based on this, this utility model designs a center-mounted lightning protection grounding rod for base stations to solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide a center-mounted lightning protection grounding rod for base stations to solve the above-mentioned technical problems.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a center-mounted lightning protection grounding rod for a base station, comprising an equipotential bonding plate, a control box, and four sets of vertical grounding bodies. A GNSS base station is connected to the top side of the equipotential bonding plate. A mounting base is also provided on the equipotential bonding plate, and a column is fixedly installed on the mounting base. A lightning rod is fixedly connected to the top of the column, and four sets of lead wires are connected to the bottom of the lightning rod. The four sets of lead wires are respectively connected to the equipotential bonding plate through the four sets of vertical grounding bodies.

[0009] By adopting the above technical solution, the lightning current is diverted and neutralized. The lightning rod attracts the charge of the thundercloud and introduces the large current into the vertical grounding body and the equipotential bonding plate through the lead wire. Then, the current is quickly dissipated to the grounding grid, thereby protecting GNSS base stations and other equipment from direct lightning strikes. At the same time, the equipotential bonding significantly reduces the risk of step voltage and backflash voltage.

[0010] Preferably, an installation plate is fixedly connected to the column near the lightning rod, and an aviation obstruction light is provided on one side of the top of the installation plate.

[0011] By adopting the above technical solution, mounting plates and aviation obstruction lights are installed on the column, which improves visibility under low visibility conditions, facilitates the positioning and maintenance of inspection personnel, and enhances safety.

[0012] Preferably, the control box is provided with a bracket, and a solar panel is provided on one side of the bracket.

[0013] By adopting the above technical solution, a bracket and solar panel are installed on the control box to utilize solar energy for power, realize green energy utilization, support the communication and status monitoring functions of the control box, and improve the system's sustainability.

[0014] Preferably, the four sets of lead wires are installed at equal angles at the bottom of the lightning rod.

[0015] By adopting the above technical solutions, the current is evenly distributed, improving the reliability and consistency of lightning protection capabilities and reducing the risk of local overload.

[0016] In summary, this application has the following beneficial technical effects: by integrating multi-level surge protection through integrated design, it reduces step voltage and electromagnetic interference, and achieves low impedance and fast current dissipation; the modular structure simplifies construction, saves space and cost, meets industry standards, improves the reliability, safety and ease of operation and maintenance of base station lightning protection, and is suitable for various base station environments in the field and urban areas.

[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0022] A center-mounted lightning protection grounding rod for a base station includes an equipotential bonding plate 1, a control box 2, and four sets of vertical grounding electrodes 3. The four sets of vertical grounding electrodes 3 are distributed around the equipotential bonding plate 1. The equipotential bonding plate 1 is a metal plate connected to the grounding grid. The vertical grounding electrodes 3 and the equipotential bonding plate 1 are buried in locations with low resistivity, selected according to the actual field conditions. The control box 2 adopts a modular design, integrating grounding, communication, and many other functions. A GNSS base station 4 is connected to the top side of the equipotential bonding plate 1. The GNSS base station 4 is used for... In the communication system, an mounting base 5 is also provided on the equipotential bonding plate 1. A column 6 is fixedly installed on the mounting base 5. A lightning rod 7 is fixedly connected to the top of the column 6. Four sets of lead wires 10 are connected to the bottom of the lightning rod 7. The four sets of lead wires 10 are respectively connected to the equipotential bonding plate 1 through four sets of vertical grounding bodies 3. The lightning rod attracts or neutralizes small-charge thunderclouds, and introduces large-charge thunderclouds into the equipotential bonding plate 1 through the lead wires 10. Then, the thunderclouds are quickly diverted to the grounding grid through the equipotential bonding, thereby protecting the base station equipment from direct lightning strike damage.

[0023] Furthermore, an installation plate 8 is fixedly connected to the column 6 near the lightning rod 7, and an aviation obstruction light 9 is installed on one side of the top of the installation plate 8 to improve visibility under low visibility conditions and facilitate the positioning of inspection personnel.

[0024] Furthermore, a bracket 11 is installed on the control box 2, and a solar panel 12 is installed on one side of the bracket 11 to provide power to the control box 2, thereby enabling some daily communication and status monitoring.

[0025] Furthermore, four sets of lead wires 10 are installed at equal angles at the bottom of the lightning rod 7 to enhance lightning protection capabilities.

[0026] The implementation principle of this embodiment is as follows: When a thundercloud approaches, the lightning rod 7 acts as a lightning arrester to attract lightning charges. Small charges in the thundercloud are neutralized, while large charges are conducted through four sets of lead wires 10 to the equipotential bonding plate 1. Since the equipotential bonding plate 1 is connected to the ground grid, the potential is quickly equalized, and the current is dissipated to the ground through the vertical grounding body 3 with low impedance, thereby preventing damage to the base station equipment. At the same time, the aviation obstruction light 9 improves visibility at night or in severe weather, and the solar panel 12 provides auxiliary power to the control box 2 to achieve automated monitoring. The entire system simplifies construction and improves lightning protection efficiency through modular design.
