[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a new type of lightning current acquisition device includes an electric box 1. One side of the electric box 1 is installed with a first column 3 through a mounting member 2, and the other side of the electric box 1 is installed with a second column 5 through the mounting member 2. The top of the first column 3 is installed with an atmospheric electric field instrument 4 through a mounting bracket. The top of the second column 5 is rotatably installed with a photovoltaic panel 7. The top of the electric box 1 is rotatably installed with an electric push cylinder 6. The electric push cylinder 6 is connected to the photovoltaic panel 7 through a sliding bracket assembly. Above the photovoltaic panel 7, a cleaning mechanism for wiping the protective glass at the top end of the photovoltaic panel 7 is installed; the sliding bracket assembly includes a sliding shaft 11 rotatably installed at the output end of the electric push cylinder 6 and lower fixing plates 9 fixedly connected to both ends of the bottom of the aluminum alloy frame of the photovoltaic panel 7. A lower sliding groove 10 for the sliding shaft 11 to slide is opened inside the lower fixing plate 9.

[0021] In this embodiment: when using this device, the photovoltaic panel 7 is used to convert light energy into electrical energy to provide electrical energy for the device. When the device is operating normally, the atmospheric electric field sensor of the atmospheric electric field instrument 4 is composed of a pair of symmetric sector-shaped metal sheets that are flat with each other, have a certain distance, and are connected together by several similar-shaped blades. The lower metal sheet is used to sense charges and is fixed and immovable, called the fixed sheet. The upper metal sheet is driven by a motor to rotate, called the moving sheet, and is connected to the ground. When the moving sheet rotates, the fixed sheet is alternately exposed to the atmospheric electric field, thereby generating an alternating electric signal. The magnitude of the signal is proportional to the atmospheric electric field strength, so as to monitor the atmospheric charge and predict the coming of thunderstorms in advance, reducing the occurrence of lightning strike accidents;

[0022] During the normal placement process of the device, due to the accumulation of dust in the atmosphere, the photoelectric conversion efficiency of the photovoltaic panel 7 will be affected. At this time, the protective glass of the photovoltaic panel 7 is cleaned through the cleaning mechanism, and the accumulated dust is cleaned, which can avoid this situation.

[0023] Please pay special attention to Figure 2 , Figure 3 and Figure 4, the cleaning mechanism includes upper fixing plates 8 fixedly connected to both ends of the top of the aluminum alloy frame of the photovoltaic panel 7. Upper sliding grooves 12 are formed inside the upper fixing plates 8. A connecting shaft 16 is movably connected inside the upper sliding grooves 12. A cleaning felt 15 is wrapped around the outer wall of the connecting shaft 16. Gears 17 are press-fitted at both ends of the outer wall of the connecting shaft 16. Tooth blocks 23 meshing with the gears 17 are integrally formed below the outside of the upper fixing plates 8. One end of the connecting shaft 16 is rotatably connected to a handle 18, and one end of the other connecting shaft 16 is detachably connected to the handle 18 through a docking component.

[0024] In this embodiment: When cleaning the photovoltaic panel 7, the connecting shaft 16 is pulled through the handle 18 to move. The connecting shaft 16 drives the cleaning felt 15 and the gears 17 to move synchronously. The moving gears 17 mesh with the tooth blocks 23. At this time, the gears 17 rotate self - clockwise. The self - rotating gears 17 drive the connecting shaft 16 to rotate in the reverse direction. The rotating connecting shaft 16 drives the rotating cleaning felt 15 to rotate, thereby cleaning the top of the protective glass of the photovoltaic panel 7 and preventing dust accumulation from affecting the photoelectric conversion efficiency of the photovoltaic panel 7.

[0025] Please refer specifically to Figure 2 , Figure 3 and Figure 4 , the docking component includes a limiting plate 20 fixedly connected to the outer periphery of the handle 18. A threaded sleeve 21 is threadedly connected to the outer wall of the handle 18 on one side of the limiting plate 20. A hexagonal head 22 is integrally formed at a position near the limiting plate 20 on the outer periphery of one end of the threaded sleeve 21. A circular hole with an outer diameter equal to that of the threaded sleeve 21 is formed inside one end of a connecting shaft 16. The handle 18 connected to the docking component is connected to the driving mechanism. The driving mechanism includes mounting plates 13 fixedly connected to the two - side edges of the aluminum alloy frame of the photovoltaic panel 7. A screw rod 14 is rotatably installed between the two mounting plates 13. The screw rod 14 is threadedly connected to one handle 18. A threaded hole 19 threadedly connected to the outer wall of the screw rod 14 is formed inside this handle 18.

[0026] In this embodiment: When the power is insufficient and manual cleaning is required, a wrench is docked with the hexagonal head 22 and the hexagonal head 22 is rotated. The hexagonal head 22 drives the threaded sleeve 21 to rotate. At this time, the threaded sleeve 21 moves outwards from the circular hole, realizing the separation of the handle 18 threadedly connected to the docking component from the connecting shaft 16. Then, the other handle 18 can be pulled to drive the cleaning mechanism for manual cleaning;

[0027] When the power is sufficient, by rotating the hexagonal head 22 in the reverse direction, the hexagonal head 22 drives the threaded sleeve 21 to rotate in the reverse direction until the threaded sleeve 21 completely enters the circular hole, and the purpose of automatically driving the cleaning mechanism can be achieved.

[0028] Please refer specifically to Figure 3, one end of an installation plate 13 is installed with a forward and reverse rotation motor, and the output shaft of the forward and reverse rotation motor is coaxially connected to a screw rod 14.

[0029] In this embodiment: By starting the forward and reverse rotation motor, the forward and reverse rotation motor can drive the screw rod 14 to rotate. When the screw rod 14 rotates, at this time, a handle 18 moves axially along the outer wall of the screw rod 14 under the action of a screw hole 19, so as to achieve the automatic cleaning effect.

[0030] Please refer specifically to Figure 1 and Figure 2 , the outer surface of the cleaning felt 15 in the moving state is in contact with the top of the protective glass of the photovoltaic panel 7.

[0031] In this embodiment: The moving and rotating cleaning felt 15 can effectively clean the top of the protective glass.

[0032] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
