Abstract
Description
Technical Field
[0001] This application relates to the field of meteorological monitoring equipment, and in particular to a lightning protection structure for an outdoor tower-type meteorological monitoring station. Background Technology
[0002] Tower-type supports are mostly used in outdoor meteorological monitoring stations where terrain and size requirements are stringent. Their smaller footprint and higher space utilization allow for better support of various meteorological monitoring components. To prevent lightning damage to these stations, lightning protection structures are installed, including lightning rods, down conductors, and grounding devices. The down conductors are typically mounted on the tower-type support using clamps.
[0003] When a lightning arrester is struck by lightning, a magnetic field and high temperature will be generated on the down conductor. To avoid the influence of the magnetic field and high temperature, the down conductor is usually wrapped with a multi-layer structure, including a plastic or rubber layer, a flame-retardant layer and an insulating layer. These layers are wrapped around the down conductor to protect other meteorological monitoring components during the lightning strike.
[0004] However, the high temperature on the down conductor can also cause plastic deformation of the rubber or plastic body, resulting in a shift in its position relative to the tower support. Over time, the down conductor is prone to deformation, and its service life is relatively short in areas with frequent thunderstorms. Utility Model Content
[0005] This application provides a lightning protection structure for an outdoor tower-type meteorological monitoring station, which improves the safety and stability of the down conductor and extends its service life.
[0006] This application provides a lightning protection structure for an outdoor tower-type meteorological monitoring station, including a tower-type support, meteorological monitoring elements, a lightning rod, a down conductor, a grounding device, a quartz sleeve, and a shielding mesh. The tower-type support has a vertical cavity in the middle, which extends through the tower-type support. Multiple meteorological monitoring elements are arranged and distributed on the tower-type support. The lightning rod is fixedly installed at the top of the tower-type support and located on the upper side of the vertical cavity. The down conductor is electrically connected to the lightning rod, vertically installed on the tower-type support and located within the vertical cavity, with both ends of the down conductor extending through the vertical cavity. The grounding device is fixedly installed underground, and the lightning rod is electrically connected to the grounding device. The quartz sleeve is installed within the vertical cavity and is fitted over the down conductor. The shielding mesh is made of a high-permeability material and is installed outside the quartz sleeve.
[0007] The down conductor in this application is vertically installed and directly connected to the lightning arrester and grounding device, which minimizes the length of the down conductor, facilitates installation, and reduces costs. The down conductor is installed inside the tower-type bracket and is wrapped with a quartz sleeve and a shielding mesh. The quartz sleeve prevents the down conductor from igniting or melting other components, thus providing fire safety. The shielding mesh can shield the magnetic field generated when lightning strikes the down conductor, preventing short-term high-intensity magnetic fields from damaging sensitive components in the meteorological monitoring elements.
[0008] In some embodiments of this application, the tower-shaped support includes multiple vertical columns, which are spaced apart circumferentially around a vertical cavity, forming a vertical cavity between the columns. The vertical cavity between the columns facilitates the installation of the down conductor and also facilitates the installation of the tower-shaped support.
[0009] In some embodiments of this application, the lightning protection structure of the outdoor tower-type meteorological monitoring station further includes multiple fixing clips. These clips are spaced apart along the axial direction of the down conductor, and are fixedly connected to at least one of the multiple vertical columns. The multiple fixing clips can fix the down conductor to the vertical column, i.e., to the tower-type support, ensuring a stable connection and conductivity between the down conductor and the lightning arrester.
[0010] In some embodiments of this application, the quartz sleeve is configured as multiple segments, with each segment located between two adjacent fixing clips. Multiple segments of the quartz sleeve facilitate fixing of the clips and also simplify the fabrication and installation of the quartz sleeve.
[0011] In some embodiments of this application, the shielding mesh is wrapped around multiple vertical posts. Wrapping the shielding mesh around the vertical posts allows for independent installation; that is, the shielding mesh is installed only after all the down conductors have been configured, thus facilitating the installation of the shielding mesh.
[0012] In some embodiments of this application, the lightning protection structure of the outdoor tower-type meteorological monitoring station further includes a stepped base, which is fixedly installed on the top of the tower-type support. A mounting hole is formed in the middle of the stepped base, communicating with a vertical cavity. The lightning arrester is fixedly installed on the stepped base and at least partially located within the mounting hole. The stepped base facilitates the connection between the lightning arrester and the tower-type support.
[0013] In some embodiments of this application, the lightning protection structure of the outdoor tower-type meteorological monitoring station also includes threaded components, and the stepped base and the tower-type support are fixedly connected by the threaded components. The threaded components can ensure a stable connection between the stepped base and the tower-type support.
[0014] In some embodiments of this application, the lightning protection structure of the outdoor tower-type meteorological monitoring station also includes a magnetic shield. The magnetic shield is disposed between the tower support and the grounding device, buried underground, and the down conductor passes through the magnetic shield. The magnetic shield can prevent the magnetic field generated by the grounding device when conducting lightning into the ground from affecting the meteorological monitoring elements.
[0015] In some embodiments of this application, the tower-shaped support includes a three-layer tower body. The three-layer tower body is easy to manufacture and can accommodate a larger number of meteorological monitoring elements. Attached Figure Description

[0026] Tower-type supports are mostly used in outdoor meteorological monitoring stations where terrain and size requirements are stringent. Their smaller footprint and higher space utilization allow for better support of various meteorological monitoring components. To prevent lightning damage to these stations, lightning protection structures are installed, including lightning rods, down conductors, and grounding devices. The down conductors are typically mounted on the tower-type support using clamps.
[0027] When a lightning arrester is struck by lightning, a magnetic field and high temperature will be generated on the down conductor. To avoid the influence of the magnetic field and high temperature, the down conductor is usually wrapped with a multi-layer structure, including a plastic or rubber layer, a flame-retardant layer and an insulating layer. These layers are wrapped around the down conductor to protect other meteorological monitoring components during the lightning strike.
[0028] However, the high temperature on the down conductor can also cause plastic deformation of the rubber or plastic body, resulting in a shift in its position relative to the tower support. Over time, the down conductor is prone to deformation, and its service life is relatively short in areas with frequent thunderstorms.
[0029] Therefore, please refer to Figure 1 and Figure 2This application provides a lightning protection structure for an outdoor tower-type meteorological monitoring station, including a tower-type support 1, a meteorological monitoring element 2, a lightning arrester 3, a down conductor 4, a grounding device 5, a quartz sleeve 7, and a shielding mesh 6.
[0030] Please refer to Figure 1 and Figure 2 The tower-shaped support 1 has a vertical cavity 11 in the middle, which runs through the tower-shaped support 1. The tower-shaped support 1 can be made of high-strength aluminum alloy. Aluminum alloy has the characteristics of low density and high strength. Compared with traditional steel, it can effectively reduce the weight of the tower body, making it easier to transport and install. At the same time, its good strength is sufficient to support the meteorological monitoring equipment and withstand a certain intensity of natural wind.
[0031] Please refer to Figure 1 and Figure 2 In addition, aluminum alloys possess excellent corrosion resistance, enabling them to maintain structural integrity for extended periods in complex outdoor environments, thus reducing maintenance costs. Their surface undergoes anodizing treatment, further enhancing corrosion resistance and effectively preventing erosion from rainwater, wind, and sand, thereby extending the service life of the tower support 1.
[0032] Please refer to Figure 1 and Figure 2 The tower support 1 can adopt a segmented truss structure design. Each truss segment consists of multiple triangular structural units. The triangular structure has the characteristic of strong stability, which can effectively enhance the tower's load-bearing capacity and wind resistance in all directions. The tower gradually tapers from bottom to top. This gradual structural design not only conforms to the principles of mechanics, but also allows the tower to better distribute its own weight and external wind and lightning impacts, while also reducing material costs to a certain extent.
[0033] Reinforcing ribs are installed at key parts of the tower, such as the connection nodes of each truss section, to further improve the stability and strength of the structure. At the same time, reasonable space is reserved inside the tower for wiring and equipment installation, ensuring convenient equipment installation and wiring safety.
[0034] High-strength bolts can be used to connect the various truss sections, facilitating on-site assembly and subsequent maintenance. Locating pins are used at the connection points for precise positioning, ensuring accurate placement of each truss section during connection and preventing misalignment that could affect structural strength. Both bolts and locating pins are made of stainless steel to guarantee excellent corrosion resistance in outdoor environments.
[0035] In addition, sealant is applied between the joint surfaces to prevent rainwater and other substances from entering the joint gaps and to avoid loosening due to corrosion. For some parts subjected to high stress, in addition to bolt connections, welding is used for auxiliary reinforcement to further improve the reliability of the connection.
[0036] Before installing the tower support 1, the foundation can be constructed first. The foundation can be made of reinforced concrete. The depth and dimensions of the foundation should be designed reasonably according to the size and weight of the tower to ensure that the foundation can provide stable support for the tower. During the foundation pouring process, anchor bolts are pre-embedded. The specifications and quantity of the anchor bolts are determined according to the load-bearing requirements of the tower.
[0037] The vertical cavity 11 in the middle of the tower-shaped support 1 can be a circular cavity, a square cavity, or a cavity formed by three or four circular cylinders and composed of multiple concave arc surfaces.
[0038] Please refer to Figure 1 The meteorological monitoring element 2 is configured in multiple ways, and the various meteorological monitoring elements 2 are distributed on the tower-shaped support 1. The meteorological monitoring element 2 may include wind direction sensor, wind speed sensor, temperature and humidity sensor, rain gauge, etc.
[0039] The wind direction sensor can be mounted on the upper part of the tower bracket 1 to obtain more accurate wind direction data. A specially designed mounting bracket is used, which is bolted to the pre-installed mounting platform at the top of the tower bracket 1. The mounting bracket can be angle-adjustable to ensure that the sensing element of the wind direction sensor is horizontal, guaranteeing measurement accuracy.
[0040] During installation, a level can be used for calibration to ensure the wind direction sensor is installed horizontally. Simultaneously, the signal transmission line of the wind direction sensor should be routed along a pre-laid wiring channel inside the tower to avoid exposing the wiring and reduce the risk of damage due to external factors.
[0041] Wind speed sensors can be integrated into wind direction sensors so that both can detect wind at the same time and save space.
[0042] The temperature and humidity sensor can be installed on the equipment platform in the middle of the tower bracket 1. This platform provides a relatively stable installation environment for the sensor, avoiding extreme effects from excessively high or low temperatures and humidity. The mounting box of the temperature and humidity sensor is fixed to the equipment platform using screws. The mounting box has good protective performance, being waterproof and dustproof.
[0043] Inside the mounting box, the temperature and humidity sensor is connected to the signal conditioning module. The signal conditioning module amplifies and filters the signal output from the sensor before transmitting it to the data acquisition device via a shielded cable. The shielded cable is laid along the internal wiring channels of the tower, effectively preventing external electromagnetic interference.
[0044] The rain gauge is installed in an open and relatively low-lying location around the tower bracket 1 to ensure that rainwater can flow smoothly into the rain gauge's collection inlet and to prevent the tower or other obstacles from affecting rainwater collection. The rain gauge is fixed to the ground using a custom-made galvanized steel mounting bracket, which offers excellent rust resistance and stability. The bottom of the mounting bracket is securely connected to the ground with expansion bolts to ensure that the rain gauge will not sway or shift during windy or rainy weather.
[0045] The rain gauge's signal transmission line uses a waterproof cable, which runs from the ground along a pre-installed cable tray on the tower into the equipment room. The cable tray is sealed to prevent rainwater from seeping in and causing short circuits. Before entering the equipment room, the signal transmission line passes through a signal isolation module. This module effectively prevents interference signals caused by factors such as lightning strikes from entering the data acquisition system, ensuring the accuracy of rainfall data transmission.
[0046] Please refer to Figure 1 The lightning rod 3 is fixedly installed on the top of the tower support 1 and located on the upper side of the vertical cavity 11. The lightning rod 3 can be a single lightning rod or multiple lightning rods. A single lightning rod can be installed on the top of the meteorological monitoring station tower. The lightning rod can be made of stainless steel, which has good conductivity and corrosion resistance. Its tip adopts a special discharge tip design, which can effectively reduce the initiation discharge voltage of lightning and increase the probability of lightning interception.
[0047] Alternatively, multiple lightning rods can be arranged in a ring. The main lightning rod is taller than the auxiliary lightning rods, forming a three-dimensional lightning interception space. The main lightning rod is made of stainless steel, which has good conductivity and corrosion resistance. Its tip features a special discharge tip design, which can effectively reduce the initiation voltage of lightning and increase the probability of lightning interception. The auxiliary lightning rods are used to expand the lightning interception range and capture lightning that may bypass the main lightning rod.
[0048] At this point, multiple lightning protection strips can be installed along the side of the tower. These strips, made of copper, are welded to the lightning rod at the top of the tower to ensure reliable electrical connection of the entire lightning arrester system. The lightning protection strips guide the lightning current rapidly downwards along the side of the tower, reducing the impact on internal equipment.
[0049] Please refer to Figure 2 The down conductor 4 is electrically connected to the lightning arrester 3. The down conductor 4 is vertically mounted on the tower-shaped support 1 and located within the vertical cavity 11, with both ends of the down conductor 4 penetrating the vertical cavity 11. The down conductor 4 can be made of a copper alloy with high conductivity and low magnetic permeability. This material generates a weaker magnetic field when conducting large currents, minimizing electromagnetic interference to surrounding sensitive components. For example, a copper-silver alloy with a high silver content has higher conductivity than ordinary pure copper and provides better suppression of magnetic fields.
[0050] The down conductor 4 and the tower bracket 1 can be insulated, that is, the gap is filled with a material with poor conductivity such as quartz to avoid direct contact between the down conductor 4 and the tower bracket 1. The down conductor 4 and the lightning arrester 3 can be fixedly connected, that is, fixed by welding or other methods according to the lightning protection engineering specifications.
[0051] Please refer to Figure 1 The grounding device 5 is fixedly installed underground, and the lightning arrester 3 is electrically connected to the grounding device 5. The grounding device 5 can adopt a composite grounding form combining horizontal and vertical grounding electrodes. The horizontal grounding electrode is made of hot-dip galvanized flat steel, laid in a ring around the tower base, and welded to the vertical grounding electrode. The vertical grounding electrode is made of galvanized angle steel, driven vertically into the ground, with the depth determined according to the soil resistivity and local lightning protection requirements, generally not less than 2.5 meters. This composite grounding form can effectively reduce grounding resistance and improve grounding effect.
[0052] A resistance-reducing agent can be added around the grounding device 5. This agent improves the conductivity of the soil and further reduces the grounding resistance. Simultaneously, the agent exhibits good stability and long-lasting effectiveness, ensuring the lightning protection performance of the grounding device 5 during long-term use.
[0053] The down conductor 4 and the grounding device 5 can also be welded together to give them better conductivity and connection stability.
[0054] Please refer to Figure 2 The quartz sleeve 7 is disposed inside the vertical cavity 11 and is fitted outside the down conductor 4. The quartz sleeve 7 is made of quartz material, and the quartz sleeve can be fitted onto the down conductor 4 at the position in the tower-shaped support 1. The quartz sleeve 7 and the down conductor 4 can be connected by abutment or by a gap.
[0055] Please refer to Figure 1 The shielding mesh 6 is made of a high-permeability material and is installed outside the quartz sleeve 7. The shielding mesh 6 can be made of a high-permeability metal material, such as permalloy, which can effectively shield the magnetic field generated by the current in the down conductor 4.
[0056] Please refer to Figure 1 The two ends of the shielding mesh 6 can be reliably connected to the grounding device 5 to form an equipotential, preventing secondary hazards caused by the accumulation of induced charges in the shielding layer. At the same time, in some sensitive areas of the down conductor 4, an insulating sleeve needs to be installed outside the shielding layer to prevent the down conductor 4 from being electrically short-circuited with surrounding objects.
[0057] Please refer to Figure 1 and Figure 2In this application, the down conductor 4 is vertically installed and directly connects to the lightning arrester 3 and the grounding device 5, which minimizes the length of the down conductor 4, facilitates installation, and reduces costs. The down conductor 4 is installed inside the tower bracket 1 and is wrapped by a quartz sleeve 7 and a shielding mesh 6. The quartz sleeve 7 can prevent the down conductor 4 from igniting or melting other components, thus playing a role in fire safety. The shielding mesh 6 can shield the magnetic field generated on the down conductor 4 when lightning strikes, preventing short-term high-intensity magnetic fields from damaging the sensitive elements in the meteorological monitoring element 2.
[0058] Please refer to Figure 3 In some examples, the tower-shaped support 1 includes multiple vertical columns 12, which are circumferentially spaced around a vertical cavity 11, forming a vertical cavity 11 between the columns 12. The vertical cavity 11 formed between the columns 12 facilitates the installation of the down conductor 4 and also facilitates the installation of the tower-shaped support 1.
[0059] In some examples, the vertical column 12 can be an aluminum alloy column, which can be fixedly connected to the tower bracket 1 body, for example, by welding or by threaded connection. The vertical column 12 can be a circular column or a prism; the number of vertical columns 12 can be 3 to 6, preferably 3.
[0060] Please return to the reference. Figure 2 In some examples, the lightning protection structure of the outdoor tower-type meteorological monitoring station also includes multiple fixing clips 13, which are spaced apart along the axis of the down conductor 4. The fixing clips 13 fix the down conductor 4 to at least one of the multiple vertical columns 12. The multiple fixing clips 13 can fix the down conductor 4 to the vertical column 12, that is, fix it to the tower-type support 1, so that the connection between the down conductor 4 and the lightning arrester 3 is stable and the conductivity is stable.
[0061] In some examples, the retaining clip 13 for securing the down conductor 4 can be made of a high-strength insulating engineering plastic, such as polyetheretherketone (PEEK). The retaining clip 13 can be semi-encircling, thus closely fitting the circular or elliptical cross-section of the down conductor 4 to provide a stable clamping force.
[0062] The inner side of the fixing clip 13 may have anti-slip texture to increase the friction between it and the down conductor 4, preventing the down conductor 4 from shifting under severe conditions such as strong winds and lightning strikes. The fixing clip 13 can be fixedly connected to one or more vertical columns 12 by stainless steel screws.
[0063] During installation, first partially wrap the fixing clip 13 around the downlead 4, align it with the installation point, and then tighten the screws. The operation is simple and the result is secure and reliable. The number of fixing clips 13 can be designed according to needs. For example, it can be set to install one fixing clip 13 at intervals of 0.5m to 1m.
[0064] Please refer to Figure 2 In some examples, the quartz sleeve 7 is configured as a multi-segment quartz sleeve, with each segment of the quartz sleeve 7 located between two adjacent fixing clips 13. The multi-segment quartz sleeve 7 facilitates the fixing of the fixing clips 13 and also makes the manufacture and installation of the quartz sleeve 7 easier.
[0065] In some examples, the quartz sleeve 7 should cover most of the area of the downleader 4 within the tower bracket 1, that is, except for the portion used to install the fixing clip 13, the quartz sleeve 7 should cover the downleader 4. In this case, the distance between two adjacent fixing brackets is the length of one quartz sleeve 7.
[0066] Please return to the reference. Figure 1 In some examples, the shielding mesh 6 is wrapped around multiple vertical posts 12. Wrapping the shielding mesh 6 around the vertical posts 12 allows it to be installed independently, that is, the shielding mesh 6 is installed after the down conductor 4 is fully configured, thus making the installation of the shielding mesh 6 convenient.
[0067] In some examples, the shielding mesh 6 can be directly wrapped around multiple vertical posts 12 and can be fixed by bolts on the fixing clips 13.
[0068] Please refer to Figure 2 In some examples, the lightning protection structure of the outdoor tower-type meteorological monitoring station also includes a step seat 8, which is fixedly installed on the top of the tower-type support 1. A mounting hole 81 is formed in the middle of the step seat 8, which communicates with the vertical cavity. The lightning arrester 3 is fixedly installed on the step seat 8 and is at least partially located in the mounting hole 81. The step seat 8 facilitates the connection between the lightning arrester 3 and the tower-type support 1.
[0069] In some examples, the step base 8 can be made of high-strength stainless steel, which has good corrosion resistance and mechanical strength, and can withstand harsh outdoor environmental conditions. The step base 8 has an overall stepped structure, consisting of multiple platforms of different heights.
[0070] Please refer to Figure 2 In some examples, the lightning protection structure of the outdoor tower-type meteorological monitoring station also includes a threaded component 82, which securely connects the stepped seat 8 to the tower-type support 1. The threaded component 82 ensures a stable connection between the stepped seat 8 and the tower-type support 1.
[0071] In some examples, the bottom platform can be securely connected to the top of the tower support 1 by welding or high-strength bolts (i.e., threaded parts 82), ensuring a stable connection between the step seat 8 and the tower body. The number of bolts can be 3 to 6.
[0072] Please refer to Figure 2In some examples, the lightning protection structure of the outdoor tower-type meteorological monitoring station also includes a magnetic shield 9, which is installed between the tower support 1 and the grounding device 5. The magnetic shield 9 is buried underground, and the down conductor 4 runs through the magnetic shield 9. The magnetic shield 9 can prevent the magnetic field generated by the grounding device 5 when conducting lightning into the ground from affecting the meteorological monitoring element 2.
[0073] In some examples, the magnetic shield 9 can be the same as the shielding mesh 6, only requiring that part of it be positioned above the lightning arrester 3. The magnetic shield 9 can be electrically connected to the lightning arrester 3 to prevent the magnetic shielding mesh 6 from generating a strong magnetic field itself.
[0074] Alternatively, when the magnetic shielding mesh 6 is buried deep, it can simply be buried underground.
[0075] In some examples, the tower support 1 comprises a three-layer tower. The three-layer tower design offers significant advantages in terms of mechanical performance, space utilization, and lightning protection. From a mechanical perspective, it better disperses stress; in terms of space utilization, it allows for the rational arrangement of different monitoring components; and in terms of lightning protection, it provides more targeted protection for equipment on each layer.
[0076] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
[0077] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
