[0002] An atmospheric electric field meter is a device capable of measuring the atmospheric electric field and its variations. It utilizes the principle of induced charge generated by a conductor in an electric field to measure the electric field.

The intensity of this change is related to the accumulation and distribution of charge in the cloud. Therefore, by measuring changes in the ground-level atmospheric electric field, changes in the electric field in high-altitude clouds can be inferred, enabling a certain degree of forecasting of the risk of lightning strikes.

The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] See also Figure 1 、 Figure 2 and Figure 3 , the embodiment of the utility model provides an atmospheric electric field measuring device, including an outer shell 1, a base plate 2, a motor bracket 3, a drive motor 4, a stator component 5, a rotor component 6, a cover 7 and a main control circuit board 8;

[0027] The bottom plate 2 is connected to one end of the outer shell 1. A cavity 9 is formed inside the bottom plate 2 and the outer shell 1. A through opening 10 is formed in the center of the bottom plate 2. The motor bracket 3 is located inside the cavity 9. The drive motor 4 and the motor bracket 3 are fixedly connected. The stator component 5 is connected to the outside of the bottom plate 2. The drive shaft of the drive motor 4 passes through the through opening 10 and is connected to the rotor component 6.

[0028] The cover 7 is connected to the stator 5, and the rotor 6 is disposed inside the cover 7. A plurality of first fan holes 11 are distributed on the cover 7, and a plurality of second fan holes 12 are distributed on the rotor 6. The atmospheric electric field accumulates on the stator 5 through the first fan holes 11 and the second fan holes 12.

[0029] The drive motor 4 and the stator 5 are both electrically connected to the main control circuit board 8 . The main control circuit board 8 is used to control the operation of the drive motor 4 and is also used to measure the atmospheric electric field accumulated on the stator 5 .

[0030] In this embodiment, the outer shell 1, the base plate 2, the motor bracket 3, the stator component 5, the rotor component 6, and the cover 7 are all made of metal; the outer shell 1 and the base plate 2 are fixedly connected by screws, and the outer shell 1 and the base plate 2 are electrically connected; a shield is formed inside the outer shell 1 and the base plate 2.

[0031] Specifically, the metal outer shell 1 and the base plate 2 are electrically connected to each other, thereby forming a shield inside, which provides shielding protection for the internal main control circuit board 8. At the same time, the motor bracket 3, stator part 5, rotor part 6, and cover body 7 are all made of metal materials. The overall structural stability is stronger, not easy to be damaged, and the service life is effectively extended.

[0032] In this embodiment, the stator 5 is insulated from the base plate 2 and connected to the main control circuit board 8 via shielded wires. An insulating layer is added between the stator 5 and the base plate 2 to insulate the stator 5 from the base plate 2. This prevents the base plate 2 from interfering with the atmospheric electric field on the stator 5, ensuring accurate atmospheric electric field measurements.

[0033] In this embodiment, the drive motor 4 is a brushless motor; the number of the first fan holes 11 and the second fan holes 12 are the same, and the shapes of the first fan holes 11 and the second fan holes 12 are the same; the area of ​​the region between two adjacent first fan holes 11 is larger than the area of ​​a single first fan hole 11; and the area of ​​the region between two adjacent second fan holes 12 is larger than the area of ​​a single second fan hole 12.

[0034] Specifically, the drive motor 4 can rotate at a uniform speed. Since the rotor part 6 made of metal material is fixed to the drive shaft of the drive motor 4, the rotor part 6 has 12 second fan holes 12, and the metal cover 7 also has 12 first fan holes 11. Whenever the metal rotor part 6 rotates to the same angle as the metal cover 7, the atmospheric electric field passes through the metal cover 7, the first fan holes 11 and the second fan holes 12 on the metal rotor part 6, and then accumulates on the metal stator part 5. After the metal rotor part 6 rotates, the atmospheric electric field will be shielded by the metal cover 7 and the metal rotor part 6, and the accumulated electric field on the metal stator part 5 will dissipate during this period.

[0035] The main control circuit board 8 receives signals from the drive motor 4 and accurately determines the measurement time. Upon receiving the corresponding angle signal, the main control circuit board 8 measures the electric field on the metal stator 5. The principle of electric field measurement itself is well known in the art. This method converts the induced charge of the stator 5 into a voltage proportional to the atmospheric electric field, and will not be further elaborated here.

[0036] In this embodiment, the stator component 5 is externally threaded, and the cover 7 is internally threaded. The stator component 5 and the cover 7 are screwed together via the external and internal threads. This facilitates disassembly of the cover 7 and the stator component 5, allowing for inspection and maintenance of the rotor component 6 inside and cleaning and maintenance of the inner wall of the stator component 5.

[0037] In this embodiment, the end of the outer shell 1 is connected to a mounting interface 13. The mounting interface 13 is used to install the entire atmospheric electric field measurement device.

[0038] To sum up, the present invention is provided with an outer shell 1, a base plate 2, a motor bracket 3, a drive motor 4, a stator part 5, a rotor part 6, a cover body 7 and a main control circuit board 8; the base plate 2 is connected to one end of the outer shell 1, a cavity 9 is formed inside the base plate 2 and the outer shell 1, and a through opening 10 is formed in the center of the base plate 2; the motor bracket 3 is inside the cavity 9, and the drive motor 4 and the motor bracket 3 are fixedly connected; the stator part 5 is connected to the outside of the base plate 2, and the drive shaft of the drive motor 4 passes through the through opening 10 and is connected to the rotor part 6; the cover body 7 is connected to the stator part 5, and the rotor part 6 is arranged inside the cover body 7; a plurality of first fan holes 11 are distributed on the cover body 7, and a plurality of second fan holes 12 are distributed on the rotor part 6; the atmospheric electric field accumulates on the stator part 5 through the first fan holes 11 and the second fan holes 12; the drive motor 4 and the stator part 5 are both electrically connected to the main control circuit board 8, and the main control circuit board 8 is used to control the operation of the drive motor 4, and the main circuit board 8 is also used to measure the atmospheric electric field accumulated on the stator part 5. The metal outer shell 1 and base plate 2 are electrically conductive with each other, thereby forming an internal shield and providing protection for the internal main control circuit board 8. The motor bracket 3, stator 5, rotor 6, and cover 7 are all made of metal, making the overall structure more stable and less susceptible to damage, effectively extending its service life. The drive motor 4 can rotate at a constant speed. Since the metal rotor 6 is fixed to the drive shaft of the drive motor 4, the rotor 6 has 12 second fan holes 12, and the metal cover 7 also has 12 first fan holes 11. Whenever the metal rotor 6 rotates to the same angle as the metal cover 7, the atmospheric electric field passes through the metal cover 7, the first fan holes 11 and the second fan holes 12 on the metal rotor 6, and then accumulates on the metal stator 5. After the metal rotor 6 rotates, the atmospheric electric field is shielded by the metal cover 7 and the metal rotor 6, and the accumulated electric field on the metal stator 5 dissipates during this period. The main control circuit board 8 receives the signal from the drive motor 4 and can accurately determine the measurement time. When the signal corresponding to the angle is received, the main control circuit board 8 measures the electric field on the metal stator 5. The present invention has a simple structure and is easy to disassemble and handle. It has strong working stability, high reliability, good shielding effect, is not easily affected by signal interference, and has more accurate measurement results.
