Description

Technical Field

[0001] This utility model relates to the field of lightning protection technology, specifically a mobile lightning protection system for photovoltaic power plants. Background Technology

[0002] Photovoltaic power generation systems are highly susceptible to direct lightning strikes and induced overvoltages due to their large exposed solar panels, towering support brackets (such as tracking brackets), and complex electrical equipment (inverters, combiner boxes, etc.). At the same time, with the popularization of bifacial power generation modules and intelligent tracking systems, the height and electrical structure of photovoltaic arrays are becoming increasingly complex, further exacerbating the risk of lightning strikes. To address this challenge, a dual-flow lightning protection system has emerged. Based on active diversion and discharge technology, it actively establishes an upward leader through a lightning arrestor to guide discharge in the early stages of thundercloud formation. Simultaneously, it is equipped with a low-impedance discharge channel to quickly discharge downward lightning current from the clouds. The system includes an ionization induction mechanism, segmented grounding electrodes, and flexible discharge cables. An intelligent monitoring unit senses changes in the electric field in real time and automatically adjusts the protection status. A specially equipped surge protector can handle both positive and negative overvoltages simultaneously, ensuring the safety of photovoltaic equipment. According to the public disclosure number CN217543248U, a lightning warning system with protective function is disclosed. This technology discloses technical solutions such as "a lightning warning system with protective function, including an atmospheric electric field instrument, a surge protector is provided on one side of the bottom of the atmospheric electric field instrument, and a grounding structure for fixing and lightning protection is provided at the bottom". Existing photovoltaic power plant lightning protection systems generally adopt fixed induction mechanism structures, whose position and height cannot be adjusted after installation. This makes it difficult to adapt to changes in different photovoltaic array layouts and the protection needs of temporary power stations. In particular, in tracking photovoltaic systems, the protection range cannot be adjusted synchronously with the rotation of the support frame, resulting in lightning protection blind spots in some areas. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a mobile lightning protection system for photovoltaic power plants. Through a quick-release structure and vehicle-mounted lifting mechanism, it enables rapid relocation and height adjustment. A single person can complete the position change and real-time adjustment. It is suitable for operation scenarios that require frequent movement, such as tracking brackets and mobile inspections, and significantly improves the mobility and utilization rate of lightning protection equipment.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mobile lightning protection system for photovoltaic power plants, comprising a sensing mechanism for diverting and discharging lightning current, wherein the sensing mechanism includes: The fixing component includes a fixing base installed in the lightning protection system, and the fixing base has three circumferentially distributed locking holes; The main component includes an outer cylinder mounted on a fixed component, an inner cylinder slidably mounted on the upper end of the outer cylinder, and a sensing needle fixed on the upper end of the inner cylinder; The mounting components include a hexagonal bolt threaded through and installed at the lower end of the outer cylinder. A guide plate is rotatably mounted on the upper end of the hexagonal bolt and located inside the lower end of the outer cylinder. Three circumferentially distributed guide frames are fixed on the top of the guide plate. Locking pins are slidably mounted on the guide frames and are slidably mounted through the outer cylinder.

[0005] Preferably, the main body component further includes a first ring seat fixed to the upper end of the outer cylinder, a first guide wheel rotatably mounted on one side inside the first ring seat, a shaft frame fixed to the lower end of the inner cylinder, a second guide wheel rotatably mounted inside the shaft frame, a third guide wheel and a fourth guide wheel rotatably mounted at the upper and lower ends of the shaft frame respectively, a second ring seat fixed to the upper end of the inner cylinder, a fifth guide wheel rotatably mounted on one side inside the second ring seat, a guide rope fixed to the outer wall of the fifth guide wheel, and the guide rope cooperates with the first guide wheel, the second guide wheel, the third guide wheel and the fourth guide wheel.

[0006] Preferably, the main body component further includes three first rollers rotatably mounted inside the first ring seat and distributed circumferentially, and three second rollers rotatably mounted inside the shaft frame and distributed circumferentially.

[0007] Preferably, the lower end of the guide rope is connected to a winding device, and the winding device is installed in the lightning protection system.

[0008] Preferably, the fixing component further includes an opening formed in the fixing seat.

[0009] Preferably, the hexagonal bolt is made of a conductive material, and its threaded portion forms a first conductive path with the fixing seat. Beneficial effects

[0010] This invention provides a mobile lightning protection system for photovoltaic power plants. Compared with existing technologies, it has the following advantages: 1. By fixing the mounting component in the desired position, inserting the lower end of the main component into the mounting component, and then rotating the hexagonal bolt to move the guide plate upward, the guide plate drives the locking pin through the guide frame to insert into the locking hole on the mounting base, so that the main component is fixed to the mounting component through the mounting component; the same applies to disassembly, simply rotate the hexagonal bolt in the opposite direction to remove the main component, transfer it to the new working position, re-insert the mounting component and lock it. The whole process does not require professional tools, and a single person can complete the position relocation; in addition, the mounting base can be pre-installed in multiple key locations in a standardized manner to form anchor points of a mobile lightning protection network, so that a single set of sensing mechanism can be used cyclically between different anchor points, significantly improving the equipment utilization rate.

[0011] 2. The winding and unwinding of the guide rope is controlled by a retractor integrated into a mobile platform, such as a lightning protection engineering vehicle or a photovoltaic inspection vehicle. Operators can adjust the lightning protection height in real time during vehicle movement. The guide rope passes through the first guide wheel, the second guide wheel, the third guide wheel, the fourth guide wheel, and the fifth guide wheel in sequence, driving the inner cylinder to move smoothly up and down along the outer cylinder. This dynamic adjustment capability enables the system to quickly adapt to the protection requirements of different sites during mobile deployment, and allows the system to maintain long-term reliability in situations requiring repeated movement, such as mobile inspections and temporary power stations.

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.

[0015] Please see Figure 1 - Figure 6This utility model provides a technical solution: a mobile lightning protection system for photovoltaic power plants, including a sensing mechanism 1 for diverting and discharging lightning current. The sensing mechanism 1 includes: The fixing component 11 includes a fixing base 111 installed in the lightning protection system, and the fixing base 111 has three circumferentially distributed locking holes 112. The main component 12 includes an outer cylinder 121 mounted on a fixed component 11, an inner cylinder 122 slidably mounted on the upper end of the outer cylinder 121, and a sensing needle 123 fixed on the upper end of the inner cylinder 122. The mounting assembly 13 includes a hexagonal bolt 131 threaded through and installed at the lower end of the outer cylinder 121. A guide plate 132 is rotatably mounted on the upper end of the hexagonal bolt 131 and located inside the lower end of the outer cylinder 121. Three circumferentially distributed guide frames 133 are fixed on the top of the guide plate 132. A locking pin 134 is slidably mounted on the guide frame 133 and is slidably mounted through the outer cylinder 121.

[0016] In this embodiment, by fixing the fixing component 11 in the required position, inserting the lower end of the main body component 12 into the fixing component 11, and then rotating the hexagonal bolt 131 to drive the guide plate 132 to move upward, the guide plate 132 drives the locking pin 134 to be inserted into the locking hole 112 on the fixing seat 111 through the guide frame 133, so that the main body component 12 is fixed to the fixing component 11 through the mounting component 13; thus realizing the quick assembly and disassembly of the main body component 12 and improving the flexibility and deployment efficiency of the sensing mechanism 1 in the mobile lightning protection system.

[0017] Specifically, the main component 12 also includes a first ring seat 124 fixed to the upper end of the outer cylinder 121. A first guide wheel 125 is rotatably installed on one side inside the first ring seat 124. A shaft frame 126 is fixed to the lower end of the inner cylinder 122. A second guide wheel 127 is rotatably installed inside the shaft frame 126. A third guide wheel 128 and a fourth guide wheel 129 are rotatably installed at the upper and lower ends of the shaft frame 126, respectively. A second ring seat 1210 is fixed to the upper end of the inner cylinder 122. A fifth guide wheel 1211 is rotatably installed on one side inside the second ring seat 1210. A guide rope 1212 is fixed to the outer wall of the fifth guide wheel 1211, and the guide rope 1212 cooperates with the first guide wheel 125, the second guide wheel 127, the third guide wheel 128, and the fourth guide wheel 129.

[0018] In this embodiment, the guide rope 1212 is wound up and down by the retractor, so that the guide rope 1212 drives the inner cylinder 122 to rise and fall along the outer cylinder 121 through the first guide wheel 125, the second guide wheel 127, the third guide wheel 128, the fourth guide wheel 129 and the fifth guide wheel 1211, so as to achieve height adjustment and adapt to different lightning protection requirements.

[0019] Specifically, the main body component 12 also includes three first rollers 1213 rotatably mounted inside the first ring seat 124 and distributed in a circular pattern, and three second rollers 1214 rotatably mounted inside the shaft frame 126 and distributed in a circular pattern.

[0020] In this embodiment, the first roller 1213 and the second roller 1214 provide multi-point support during the lifting and lowering of the inner cylinder 122 along the outer cylinder 121, reducing swaying and ensuring the stability and reliability of the lifting process. In addition, the roller structure reduces frictional resistance, making the lifting operation smoother and reducing component wear.

[0021] Specifically, the lower end of the guide rope 1212 is connected to a winding device, and the winding device is installed in the lightning protection system.

[0022] In this embodiment, a retractor is used to control the winding and unwinding of the guide rope 1212, which is convenient to operate and can quickly adjust the height of the sensing mechanism 1, thereby enhancing the dynamic adaptability of the lightning protection system.

[0023] Specifically, the fixing component 11 also includes an opening 113 formed on the fixing base 111.

[0024] In this embodiment, the opening 113 facilitates the insertion of a wrench into the opening 113 to rotate and adjust the hex bolt 131, which is particularly suitable for installation needs in confined or complex environments.

[0025] Specifically, the hex bolt 131 is made of conductive material, and its threaded portion forms a conductive path with the fixing seat 111.

[0026] In this embodiment, a first conductive path is formed between the hexagonal bolt 131 and the fixing seat 111, a second conductive path is formed between the guide plate 132 and the locking pin 134, and a third conductive path is formed by the contact between the locking pin 134 and the inner wall of the lock hole 112. Through the series connection of the first, second and third conductive paths, a complete electrical connection channel is formed between the fixing component 11 and the main component 12.

[0027] The working principle and usage process of this utility model are as follows: First, the fixing component 11 is fixed in the required position. Then, the lower end of the main body component 12 is inserted into the fixing component 11. Next, the hexagonal bolt 131 is rotated to drive the guide plate 132 to move upward. The guide plate 132 drives the locking pin 134 to be inserted into the locking hole 112 on the fixing seat 111 through the guide frame 133, so that the main body component 12 is fixed to the fixing component 11 through the mounting component 13. This enables the quick assembly and disassembly of the main body component 12, improving the flexibility and deployment efficiency of the sensing mechanism 1. The guide rope 1212 is wound and unwound by a retractor, allowing it to drive the inner cylinder 122 to rise and fall along the outer cylinder 121 via the first guide wheel 125, the second guide wheel 127, the third guide wheel 128, the fourth guide wheel 129, and the fifth guide wheel 1211, thus achieving height adjustment to meet different lightning protection requirements. Furthermore, the first roller 1213, in conjunction with the second roller 1214, provides multi-point support during the lifting and lowering of the inner cylinder 122 along the outer cylinder 121, reducing swaying and ensuring the stability and reliability of the lifting process. In addition, the roller structure reduces frictional resistance, making the lifting operation smoother and reducing component wear.
