Abstract
Description
Technical Field
[0001] This utility model relates to the intersection of satellite navigation and positioning technology and disaster prevention and mitigation engineering, and in particular to a lightning protection device and an integrated continuous observation room for outdoor lightning protection. Background Technology
[0002] The integrated continuous field observation chamber is a crucial component of the base station, constructed of metal and permanently placed in the field. It houses vital observation equipment such as GNSS receivers, meteorological equipment, power supply systems, and network equipment, providing a safe and secure environment for these instruments. However, due to the chamber's materials and the surrounding environment, it is highly susceptible to lightning strikes, which could damage the power supply and equipment. Therefore, lightning protection devices are essential for preventing lightning damage to the equipment in the integrated continuous field observation chamber.
[0003] Traditional lightning protection systems involve constructing independent lightning rods around the observation room. These rods primarily consist of a concrete base, the main body of the lightning rod, a support structure, and a grounding grid. To ensure 45° coverage of the integrated observation room, the total height of the lightning rod is generally the height of the observation room plus the distance between the observation room and the lightning rod. The construction of the lightning rod involves building a concrete base and support structure, which requires waiting for the concrete to solidify, thus the construction period is generally about one week. If the lightning rod is too tall and requires a larger base, the construction period will be longer. Furthermore, the main body of the lightning rod needs to meet certain height requirements due to technical constraints, necessitating more metal material. This leads to the need for a larger base and more reliable support structures, all of which incur significant additional costs. Utility Model Content

The grounding stakes are connected to the vertical conductor, and one end of the vertical conductor is connected to the lightning rod. The lightning rod is a stainless steel pipe with a closed needle-shaped tip. The tail end of the lightning rod is fixed to the top of the integrated continuous field observation room. The lightning rod is used to receive lightning strikes and guide the lightning current into the lightning protection device. The grounding stake is made of flat copper and is used to discharge the lightning current to the ground, achieving effective grounding. The vertical conductor is made of round steel and is used to connect the lightning rod and the grounding stake, forming a complete lightning current discharge channel.

[0013] In the intersection of satellite navigation and positioning technology and disaster prevention and mitigation engineering, Global Navigation Satellite System (GNSS) reference stations are typically deployed in outdoor environments, exposed to the risk of lightning strikes for extended periods. To ensure equipment safety, lightning protection devices (such as lightning rods, down conductors, and grounding systems) are widely used. Independent lightning rods are constructed around the observation room. These lightning rods mainly consist of a concrete base, the main body of the lightning rod, a support structure, and a grounding grid. To ensure 45° coverage of the integrated observation room, the total height of the lightning rod is generally the height of the observation room plus the distance between the observation room and the lightning rod. To address or improve the aforementioned technical problems, this utility model provides a lightning protection device for use in an integrated continuous field observation room. The device includes a lightning rod, a vertical conductor, and one or more grounding stakes.

The tail end of the lightning rod is fixed to the top of the integrated continuous field observation room. The lightning rod is used to receive lightning strikes and guide the lightning current into the lightning protection device. The grounding stakes are made of flat copper and are used to discharge the lightning current to the ground, achieving effective grounding. The vertical conductors are made of round steel and are used to connect the lightning rod and the grounding stakes, forming a complete lightning current discharge channel. This integration of the integrated continuous field observation room and the lightning protection device significantly shortens the construction cycle and reduces construction costs.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.
[0023] This utility model relates to a lightning protection device for use in an integrated continuous observation room in the field. It mainly consists of three parts: a lightning rod, a vertical conductor, and a grounding stake. Figure 1 As shown, Figure 1 This is a schematic diagram of the connection structure of a lightning protection device provided in an embodiment of the present utility model.
[0024] refer to Figure 1The lightning protection device includes: a lightning rod 101, a vertical lead wire, and one or more grounding stakes 102. The grounding stakes 102 are connected to the vertical lead wire, and one end of the vertical lead wire is connected to the lightning rod 101. The lightning rod 101 is a stainless steel pipe with a closed needle-shaped top. The tail end of the lightning rod 101 is fixed to the top of the integrated continuous observation room in the field. The lightning rod 101 is used to receive lightning and guide the lightning current into the lightning protection device. The grounding stakes 102 are made of flat copper and are used to discharge the lightning current to the ground to achieve effective grounding. The vertical lead wire is made of round steel and is used to connect the lightning rod 101 and the grounding stakes 102 to form a complete lightning current discharge channel.
[0025] In one possible implementation, the lightning rod 101 has a diameter of not less than 5 centimeters (cm), a closed needle-like structure at the top, a height of not less than 1 meter (m), and is connected to the vertical lead wire by welding.
[0026] The stainless steel pipe structure, with a diameter of at least 5 cm, provides sufficient mechanical strength to withstand strong wind loads. The closed, needle-shaped tip creates a high-curvature electric field concentration point, significantly improving the success rate of lightning strikes. The large-section steel pipe, combined with welded connections, ensures that the conductor temperature rise is controlled within a safe range when lightning current passes through, avoiding the risk of melting. The integrated stainless steel material and welded structure eliminate electrochemical corrosion at the connection points. The closed, needle-shaped structure reduces high-frequency electromagnetic radiation during lightning strikes.
[0027] In one possible implementation, the vertical lead wire is made of round steel with a cross-sectional area of not less than 48 square millimeters (mm²). 2 The length should not be less than 8 meters. Round steel with a cross-sectional area of ≥48 square millimeters (equivalent to a diameter of ≥8 millimeters) can safely carry lightning current without causing excessive temperature rise in the conductor, thus avoiding the risk of melting.
[0028] In one possible implementation, each grounding stake 102 has a thickness of not less than 3 mm and a length of not less than 1 meter. The grounding stake 102 is connected to the vertical lead wire by welding. Copper has a low annual corrosion rate in soil, and the 1-meter length design meets the effective depth requirement of the vertical grounding electrode and facilitates manual hammering construction.
[0029] In one possible implementation, the grounding stakes 102 on the vertical lead are spaced at least 1 meter apart, and each grounding stake 102 is inserted into the ground to a depth of at least 0.5 meters. The minimum 1-meter spacing ensures that the soil electric field distribution among multiple grounding stakes 102 does not interfere with each other. The 0.5-meter burial depth allows the grounding electrode to meet the requirements of rapid conductivity while controlling the step voltage during lightning current discharge within safe limits. The combination of burial depth and spacing parameters can form a three-dimensional discharge network in the horizontal direction, which improves the discharge speed compared to the traditional single grounding electrode.
[0030] In one example, the overall structure of the lightning protection device is as follows: Figure 2As shown, the lightning rod 101 is 1 meter high, with a closed needle-shaped top. The vertical lead is 3 meters high, and the grounding stakes 102 on the vertical lead are spaced at least 1 meter apart. There are a total of 6 grounding stakes 102, all of which are inserted 0.5 meters into the ground (i.e., 0.5 meters of them are below the ground level).
[0031] In one example, the tail end of the lightning rod 101 is fixed to the top of the integrated continuous observation room in the field, such as... Figure 3 As shown, the tail end of the lightning rod 101 of the lightning protection device is fixed to the top of the field integrated continuous observation room. The top of the field integrated continuous observation room has a reserved base for the lightning rod 101, which can fix the lightning rod 101 to the top surface of the observation room.
[0032] In one example, the integrated continuous field observation room is a type of Global Navigation Satellite System (GNSS) reference station. A GNSS reference station is a fixed ground-based observation station that provides data support for high-precision positioning, coordinate frame establishment, and crustal movement monitoring by continuously receiving GNSS signals over a long period. It integrates satellite positioning, communication, and data processing technologies and is widely used in surveying, geological disaster early warning, and engineering construction.
[0033] In one possible implementation, the grounding area of all grounding stakes 102 on the vertical lead wire is not less than 0.3 square meters (m²). 2 The grounding area can further ensure that the grounding electrode can not only meet the requirements of rapid conduction, but also control the step voltage during lightning current discharge within the safe limit.
[0034] In one possible implementation, the vertical lead wire should have no more than five bends. This avoids increasing the inductive reactance of the high-frequency lightning current path, and reducing bends further prevents the protective layer (galvanized or epoxy) from cracking at the bends. Specifying an upper limit on the number of bends allows for quantifiable installation processes, ensuring that the temperature rise at the bends does not exceed the threshold, thus extending service life.
[0035] In one example, the connection method between the lightning rod and the grounded metal of the lightning protection device is as follows: Figure 4 As shown, the grounding stake and lightning rod are connected by vertical leads, and the connection method is welding. The entire lightning protection device is a custom-made device that can be directly and quickly installed in the reserved base on the top of the observation room without the need for additional concrete base and support devices, reducing the amount of materials required for the main body of the lightning rod and significantly shortening the construction cycle and construction cost.
[0036] In one possible implementation, the lightning rod 101, the grounding stake 102, and the vertical lead wire all have anti-corrosion coatings, which are suitable for most outdoor scenarios. Different anti-corrosion coatings can be selected according to different outdoor scenarios to effectively improve service life.
[0037] In one possible implementation, the vertical lead is laid perpendicularly to the exterior wall of the integrated continuous field observation station, and is fixedly insulated from the building throughout its length. This vertical laying creates the shortest possible path, significantly reducing the conduction time of the lightning current waveform and thus reducing the intensity of LEMP (lightning electromagnetic pulse) radiation. The insulated fixation to the building can be achieved by wrapping the lead with insulating materials (such as rubber) or by using PVC insulating clips, ensuring a certain air gap between the lead and the wall. This ensures insulation even in high humidity environments, completely eliminating the possibility of discharge to the building.
[0038] In one example, anti-seismic supports can be installed at 0.5m intervals to significantly reduce the swing amplitude of the lead wire and avoid metal fatigue fracture caused by wind vibration.
[0039] The above-described embodiments of this utility model are applied to an integrated continuous field observation chamber, comprising a lightning rod, a vertical conductor, and one or more grounding stakes. The grounding stakes are connected to the vertical conductors, one end of which is connected to the lightning rod. The lightning rod is a stainless steel pipe with a closed needle-shaped tip, and its tail end is fixed to the top of the integrated continuous field observation chamber. The lightning rod is used to receive lightning strikes and guide the lightning current into the lightning protection device. The grounding stakes are made of flat copper and are used to discharge the lightning current to the ground, achieving effective grounding. The vertical conductors are made of round steel and are used to connect the lightning rod and the grounding stakes, forming a complete lightning current discharge channel. This integration of the integrated continuous field observation chamber and the lightning protection device significantly shortens the construction cycle and reduces construction costs.
[0040] Accordingly, another embodiment of this utility model also provides an integrated continuous observation room for outdoor lightning protection, including the lightning protection device and the integrated continuous observation room for outdoor use provided in the above embodiment. The lightning protection device and the integrated continuous observation room for outdoor use are combined to form a complete lightning current discharge channel applied to the integrated continuous observation room for outdoor use.
[0041] Those skilled in the art will understand that the above embodiments are specific examples of implementing this utility model, and in practical applications, various changes can be made in form and detail without departing from the spirit and scope of this utility model. Any person skilled in the art can make various alterations and modifications without departing from the spirit and scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
