Description

Technical Field

[0002] In photovoltaic (PV) power generation systems, lightning rods are crucial equipment for protecting against lightning strikes, and their effectiveness directly impacts the safe operation of PV equipment. While traditional fixed lightning rods provide basic protection, they have significant drawbacks: in non-thunderstorm weather, excessively tall lightning rods may become roosting sites for birds or entanglements for debris, increasing the risk of shading of PV modules and maintenance costs; furthermore, fixed installations are prone to stress concentration in harsh environments such as strong winds and snow accumulation, leading to equipment damage. Some height-adjustable lightning rods, while adjustable in height, rely on manual operation or simple timer control, failing to respond to real-time weather changes. Delayed operation during thunderstorms may result in protection failure. As PV power plants develop towards large-scale and unmanned operations, there is an urgent need for a highly reliable lightning rod device that can automatically raise and lower based on weather conditions to achieve precise protection and intelligent management of PV equipment.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0016] like Figures 1 to 7 As shown, this utility model provides a rising lightning rod for protecting photovoltaic systems, comprising: A fixing plate 1, with a first fixing post 2 and a second fixing post 3 fixedly sleeved inside the top of the fixing plate 1; The lifting mechanism is located inside the first fixed column 2; The lifting mechanism includes a first threaded sleeve 4, the bottom end of which is fixedly connected to the bottom end of the first fixed column 2. A rotating column 5 is threadedly fitted onto the outer surface of the first threaded sleeve 4. The outer surface of the rotating column 5 is movably fitted onto the interior of the first fixed column 2. A second threaded sleeve 6 is fixedly installed at the bottom end of the interior of the rotating column 5. A first telescopic column 7 is threadedly fitted onto the outer surface of the second threaded sleeve 6. The outer surface of the first telescopic column 7 is movably fitted onto the interior of the rotating column 5. A lifting plate 8 is fixedly fitted onto the top end of the first telescopic column 7. A lightning rod 9 is fixedly installed onto the top end of the lifting plate 8. A second telescopic column 10 is fixedly fitted onto the interior of the lifting plate 8. A third telescopic column 11 is movably fitted onto the outer surface of the second telescopic column 10. The outer surface of the third telescopic column 11 is movably fitted onto the interior of the second fixed column 3.

[0017] The fixed plate 1 serves as the basic load-bearing component, used to fix and install the first fixed column 2 and the second fixed column 3, providing a stable installation foundation for the entire device. The first and second fixed columns 2 and 3 not only provide support but also offer installation space and motion guidance for the lifting mechanism and internal telescopic structure. The first threaded sleeve 4 within the lifting mechanism is fixed to the bottom inside the first fixed column 2, providing a threaded transmission fit for the rotating column 5. The rotating column 5 is threadedly connected to the first threaded sleeve 4 and movably sleeved within the first fixed column 2, achieving up-and-down movement along the first threaded sleeve 4 through rotation. The second threaded sleeve 6 is fixed to the bottom inside the rotating column 5. The first telescopic column 7 is used to drive the movement of the first telescopic column 7; the first telescopic column 7 is threadedly connected to the second threaded sleeve 6 and is movably sleeved inside the rotating column 5, and its top end is connected to the lifting plate 8, which is driven by the up and down movement of the lifting plate 8; the lifting plate 8 is used to install the lightning rod 9, so as to realize the lifting and lowering of the lightning rod 9; the second telescopic column 10 is fixed inside the lifting plate 8 and is movably sleeved with the third telescopic column 11, which is in turn movably sleeved inside the second fixed column 3. The telescopic structure composed of the three plays a limiting and guiding role for the lifting plate 8 and the first telescopic column 7, ensuring that the first telescopic column 7 can only move along the axial direction, thereby cooperating to realize the stable lifting and lowering movement of the lightning rod 9.

[0018] Among them, a motor 12 is fixedly installed at the bottom end of the fixed plate 1, and a rotating shaft 13 is fixedly sleeved at the output end of the motor 12. The outer surface of the rotating shaft 13 is movably sleeved with the interior of the fixed plate 1 and the interior of the bottom end of the first fixed column 2.

[0019] The motor 12 at the bottom of the fixed plate 1 serves as a power source, providing rotational power for the entire lifting mechanism; the rotating shaft 13 at the output end of the motor 12 passes through the bottom of the fixed plate 1 and the first fixed column 2, and is used to transmit the power of the motor 12 to the upper component.

[0020] Among them, a square rod 14 is fixedly installed at the top of the rotating shaft 13, and the outer surface of the square rod 14 is movably connected to the inner part of the bottom end of the rotating column 5.

[0021] The square rod 14 at the top of the rotating shaft 13 is movably connected to the bottom of the rotating column 5. Due to the square design of the square rod 14, when it rotates under the drive of the rotating shaft 13, it can drive the rotating column 5 to rotate synchronously, realizing the effective transmission of power from the rotating shaft 13 to the rotating column 5, and ensuring that the rotating column 5 moves in the first fixed column 2 in a predetermined manner.

[0022] The outer surface of the first fixed column 2 is fixedly sleeved with a support plate 15, and the interior of the support plate 15 is fixedly sleeved with the outer surface of the second fixed column 3.

[0023] The support plate 15 on the outer surface of the first fixed column 2 is connected to the second fixed column 3, which serves to connect and reinforce, enhance the structural stability between the first fixed column 2 and the second fixed column 3, provide good support for the second fixed column 3, and ensure the structural stability of the entire device during operation.

[0024] The bottom end of the fixing plate 1 is fixedly installed with a base 16, and the base 16 is provided with bolts 17.

[0025] Bolts 17 on the base 16 are used to securely connect the entire device to foundation components such as piles buried in the soil, so that the device can be firmly installed and remain stable during the raising and lowering of the lightning rod 9 and resisting lightning.

[0026] The control panel 18 is embedded inside the front of the first fixed column 2. The control panel 18 has a built-in controller and data storage module and is electrically connected to the motor 12.

[0027] The control panel 18, which is embedded in the front of the first fixed column 2, has a built-in controller and data storage module and is the control core of the entire device. The control panel 18 is electrically connected to the motor 12 and is used to receive signals, process data, and send control signals to the motor 12 according to preset programs or external instructions, thereby accurately controlling the operation of the motor 12 and realizing intelligent control of the raising and lowering action of the lightning rod 9.

[0028] A signal receiver 19 is fixedly installed on the front of the first fixed column 2, and the signal receiver 19 is electrically connected to the control panel 18.

[0029] The signal receiver 19 on the front of the first fixed column 2 is electrically connected to the control panel 18. Its function is to receive external signals about weather conditions in real time, such as warning signals of impending thunderstorms, and transmit the received signals to the control panel 18 in a timely manner, providing a basis for the control panel 18 to control the operation of the motor 12 and other components, so that the device can automatically respond to changes in the external environment.

[0030] A buzzer 20 and a warning light 21 are fixedly installed on the front of the first fixed column 2. Both the buzzer 20 and the warning light 21 are electrically connected to the control panel 18.

[0031] The buzzer 20 and warning light 21 on the front of the first fixed column 2 are electrically connected to the control panel 18. When the control panel 18 receives a thunderstorm weather signal and makes a judgment, it sends an activation signal to the buzzer 20 and warning light 21. The buzzer 20 emits a continuous and sharp alarm sound, and the warning light 21 emits a red light to remind the staff in the photovoltaic site to evacuate the dangerous area in time, which plays a safety warning role and ensures the safety of personnel.

[0032] Working principle and usage process of this utility model: In use, the entire device is first securely connected to the foundation pile buried in the soil by bolts 17 on the base 16. When the signal receiver 19 receives a signal that thunderstorms are about to occur, it will transmit the signal to the control panel 18. At this time, the controller built into the control panel 18 will send signals to the motor 12, the buzzer 20 and the warning light 21. The buzzer 20 will immediately emit a continuous and sharp alarm sound, and the warning light 21 will simultaneously emit a red light to remind the staff in the photovoltaic site to evacuate quickly.

[0033] Simultaneously with the warning, motor 12 starts running. At this time, shaft 13 drives square rod 14 to rotate. Although square rod 14 is movably sleeved inside the bottom end of rotating column 5, due to its square design, when shaft 13 drives square rod 14 to rotate, square rod 14 will drive rotating column 5 to rotate inside the first fixed column 2. Furthermore, because the outer surface of rotating column 5 is threadedly sleeved with the first threaded sleeve 4, rotating column 5 will move upwards along the outer surface of the first threaded sleeve 4 while rotating along it. At the same time, rotating column 5 also moves upwards along the outer surface of square rod 14.

[0034] Furthermore, when the rotating column 5 rotates, the second threaded sleeve 6 fixed inside it rotates accordingly. Since the outer surface of the second threaded sleeve 6 is threadedly fitted with the first telescopic column 7, and the outer surface of the first telescopic column 7 is movably fitted with the interior of the rotating column 5, theoretically, the rotation of the second threaded sleeve 6 would drive the first telescopic column 7 to rotate together. However, at this time, the telescopic structure composed of the lifting plate 8, the second telescopic column 10, the third telescopic column 11, and the second fixed column 3 comes into play. The second telescopic column 10 is fixed inside the lifting plate 8, and its outer surface is movably fitted with the third telescopic column 11. The third telescopic column 11 is in turn movably fitted with the interior of the second fixed column 3. This structure forms a limiting constraint on the lifting plate 8 and the first telescopic column 7 connected to it, so that the first telescopic column 7 can only move axially and cannot rotate. Therefore, when the second threaded sleeve 6 rotates, under the action of threaded transmission, the first telescopic column 7, which cannot rotate, can only move upward along the interior of the rotating column 5.

[0035] As the first telescopic column 7 moves upward along the interior of the rotating column 5, and the rotating column 5 moves upward along the interior of the first fixed column 2, the second telescopic column 10 moves upward synchronously along the interior of the third telescopic column 11, and the third telescopic column 11 moves upward synchronously along the interior of the second fixed column 3. Simultaneously, the lifting plate 8, fixedly sleeved at the top of the first telescopic column 7, drives the lightning rod 9 to rise upward until it reaches a predetermined height, enabling the lightning rod to automatically rise during thunderstorms and enter lightning protection mode, providing effective lightning protection for photovoltaic equipment. After the thunderstorm ends, the control panel 18 sends a reverse operation signal to the motor 12, causing the rotating shaft 13 to drive the square rod 14 to rotate in the opposite direction, causing the rotating column 5 and the first telescopic column 7 to move downward, and the lightning rod 9 to descend accordingly, reducing its height and minimizing potential impacts during non-thunderstorm weather.
