[0028] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art.

Therefore, they should not be construed as limitations on this utility model.
[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0030] Given that current technologies typically employ atmospheric electric field meters to monitor the electric field around the atmosphere in order to achieve lightning warnings, the atmospheric electric field meters need to be kept clean during operation. If they are obstructed or accumulate dust, the accuracy of the monitoring will be affected. Traditional atmospheric electric field meters require regular manual cleaning of surface dust or obstructions.
[0031] like Figure 1-4 As shown, this utility model embodiment provides an intelligent early warning device for power grid lightning disasters, including: an early warning component 10, which includes a pole 11; an electrical control box 12, fixedly connected to the outer wall of the pole 11; a solar panel 13, fixedly connected to the outer wall of the pole 11; an atmospheric electric field meter 14, installed at the top of the pole 11; and a lightning rod 15, fixedly connected to the outer wall of the top of the pole 11.
[0032] The pole 11 is fixed at the monitoring location. The electrical control box 12 contains a data processing module, a communication module, electrical control equipment, and a battery. The communication module is responsible for receiving the monitoring data from the atmospheric electric field meter 14 and transmitting the data to the cloud platform via 4G / 5G or satellite communication. The electrical control box 12 integrates a timing circuit and a power distribution switch. The timing circuit controls the periodic operation of the cleaning components, while the power distribution switch and battery can provide power to each component. The solar panel 13 provides off-grid power support for the device. The atmospheric electric field meter 14 is installed at the top of the pole and uses a high-sensitivity sensor to monitor changes in atmospheric electric field intensity in real time (within ±30kV / m range) and capture signals of thundercloud charge accumulation. After the data is processed by the data processing module, a lightning warning classification (such as yellow / orange / red three levels) is triggered. The lightning rod 15 is fixed on the outer side of the top of the pole and the lightning current is introduced into the ground through an independent grounding system (grounding resistance ≤4Ω) to protect the core equipment from direct lightning damage. For the specific warning principle, please refer to the lightning warning system and lightning warning method based on lightning and electric field detection technology proposed in patent number (CN113533835B).
[0033] The outermost wall of the top of the warning component 10 is provided with a circular motion component 20. The circular motion component 20 includes an annular tooth 21, which is fixedly connected to the outer wall of the rod 11; a sliding block 22, which is slidably connected to the outer wall of the annular tooth 21; a drive motor 23, which is installed at the bottom of the sliding block 22; and a drive tooth 24, which is rotatably connected to the inside of the sliding block 22, with its bottom rotating shaft connected to the output shaft of the drive motor 23, and its outer wall meshing with the outer wall of the annular tooth 21.
[0034] The ring tooth 21 is fixed to the outside of the rod body, and the drive tooth 24 is connected to the output shaft of the drive motor 23. Through gear meshing, the sliding block 22 is driven to move along the ring track. When cleaning, the drive motor 23 is started, which drives the drive tooth 24 to rotate, and the drive tooth 24 drives the sliding block 22 to move along the ring track, thus achieving the purpose of circular motion.
[0035] A flipping brush assembly 30 is provided on the top of the sliding block 22. The flipping brush assembly 30 cleans the outer wall of the atmospheric electric field meter 14. The flipping brush assembly 30 includes a bearing seat 31 fixedly connected to the top of the sliding block 22; a flipping block 32 rotatably connected to the inside of the bearing seat 31; a flipping motor 33 installed on the outer side wall of the bearing seat 31, and an output shaft connected to the rotating shaft of the flipping block 32; a brush body 34 fixedly connected to the top of the flipping block 32; and a rubber block 35 provided on one side of the brush body 34.
[0036] The bearing seat 31 is fixed to the top of the sliding block 22. The flipping motor 33 drives the flipping block 32 to rotate, so that the flipping block 32 drives the brush body 34 to flip, enabling the brush body 34 to conform to the atmospheric electric field meter 14 to meet the cleaning requirements of complex surfaces. When not cleaning, the flipping motor 33 drives the brush body 34 to flip, making the brush body 34 in a horizontal state to avoid the brush body 34 blocking the atmospheric electric field meter 14.
[0037] Further, the sliding block 22 is in a "C" shape. The sliding block 22 is designed in a "C" shape, and the upper and lower ends of the inner wall wrap the annular tooth track, enhancing the structural stability.
[0038] Further, the electrical input end of the driving motor 23 is connected with a timing circuit. The timing circuit controls the driving motor 23 to work through a frequency converter (prior art, not elaborated here). The timing circuit controls the cleaning frequency (such as starting regularly every day) to avoid dust accumulation affecting the sensitivity of the electric field meter.
[0039] Further, the circular motion component 20 further includes a limiting chute 25 symmetrically opened on the upper and lower surfaces of the annular tooth 21; a limiting slider 26 fixedly connected to the inner side wall of the sliding block 22 and slidably connected with the limiting chute 25. The limiting chute 25 and the limiting slider 26 cooperate to limit the radial displacement of the limiting slider 26 and prevent the gears from disengaging.
[0040] Further, the flipping motor 33 is a worm reduction motor. The worm reduction motor drives the flipping brush assembly 30 to ensure that the cleaning action is precisely controllable, and the worm reduction motor has self-locking.
[0041] Further, the brush body 34 is composed of two plate bodies. The first section is a plate body in a vertical state, and the second section is a plate body in an inclined state with a certain angle. The brush body consists of a vertical section and an inclined section, conforming to the outer wall curved surface of the atmospheric electric field meter 14 and covering without dead angles.
[0042] Further, the rubber block 35 is a flexible rubber block. The flexible rubber block (hardness ≥ 80HB) is wear-resistant and antistatic, avoiding secondary interference during the cleaning process. During the regular maintenance by the staff, the rubber block 35 can be cleaned to ensure the subsequent cleaning effect.
[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
