Fig. 1 illustrates a structure of a moon detection electrostatic dust collection device according to an embodiment of the present utility model.
As shown in fig. 1, the moon detection electrostatic dust collection device provided by the embodiment of the utility model comprises an insulating handle 1, a voltage generator 2, an insulating shielding cover 3, a moon dust collection structure and a moon dust collection structure; wherein the insulating shielding cover 3 is of an arc structure, and the opening of the insulating shielding cover is downward; the voltage generator 2 is fixed on the outer side of the insulating shielding cover 3, the insulating handle 1 passes through the insulating shielding cover 3 downwards and is fixedly connected with the moon dust collecting structure, the moon dust collecting structure is within the coverage range of the insulating shielding cover 3, the voltage generator 2 is used for providing high-voltage current for the moon dust collecting structure, the moon dust collecting structure generates uniform electrostatic field after receiving the high-voltage current, and moon dust is collected in an electrostatic adsorption mode;
and a recovery hole is formed in the position, close to the edge, of the insulating shielding cover, the moon dust collecting structure is fixed at the position, located at the recovery hole, of the outer side of the insulating shielding cover 3, and when the insulating handle 1 is operated to turn the insulating shielding cover 3 upwards, moon dust collected by the moon dust collecting structure falls back into the moon dust collecting structure.
The insulating handle 1 can be used by hand or will be fixed on a movable platform (e.g. the end of a mechanical arm) so that the dust collection device can be moved over the lunar surface, increasing the collection coverage area and flexibility.
The moon dust collection structure comprises a metal disc 41 and metal thin rods 42, wherein the center of one surface of the metal disc 41 is welded with an insulating handle 1, the positive electrode of a voltage generator 2 is connected with the metal disc 41, the negative electrode of the voltage generator 2 is connected with a grounding wire 21, the grounding wire 21 is led out from the inside of the insulating handle 1, the other surface of the metal disc 41 is welded with the metal thin rods 42, the metal thin rods 42 are uniformly distributed along the radial direction of the metal disc 41, the tail ends of the metal thin rods 42 are spherical, metal balls 43 are formed, the metal thin rods 42 serve as conductors, and the metal balls 43 serve as generating uniform electrostatic fields and adsorbing moon dust.
Since the smaller the curvature of the conductor surface, the smaller the charge density, i.e., the stronger the electric field, the end of the metal pin 42 is set to be spherical,
since the smaller the curvature of the conductor surface, i.e. the sharper the edge, the greater the charge density, the stronger and uncontrollable the electric field at the corners of the metal pin 42. While the curvature of the sphere surface is the same, i.e., the inverse of the radius, a uniform electric field is generated, so the end of the metal thin rod 42 is designed to be spherical.
The metal disc 41 is preferably a metal disc, the diameter of the metal disc is 18-22 cm, and the thickness of the metal disc is 0.5cm; the length of the metal thin rods 42 is 1-2 cm, the diameter of the metal thin rods 42 is 0.1-0.2 cm, the radius of the metal pellets 43 is 0.2-0.5 cm, the distance between the metal thin rods 42 is at least 4 times of the radius r of the metal pellets, and the adjacent metal pellets 43 are guaranteed not to be contacted.

Electrically operated valve 53 may be CIA Yang Diefa, for example, model D941X-10S or model DN 40.
After the metal disc 41 is powered off, the moon dust adsorbed on the metal balls 43 generally falls naturally, but the moon dust with small particle size may be continuously adhered to the metal balls 43 by van der Waals force, and the moon dust can generate inertia force by vibration to overcome the van der Waals force, so that the complete collection of the moon dust is realized.
Therefore, two piezoelectric ceramics 6 (namely, ultrasonic transducers) are symmetrically arranged at the position 20-40 mm away from the center of the surface of the metal disc 41, away from the metal thin rod 42, the two piezoelectric ceramics 6 are hinged with the insulating handle 1, and the metal disc 41, the metal thin rod 42 and the metal balls 43 vibrate through the two piezoelectric ceramics 6 to accelerate the falling of moon dust.

As shown in fig. 3 and 4, when the voltage generator 2 supplies a high voltage current to the metal disk 41, the metal balls 43 generate a uniform electrostatic field. Since the insulating shield 3 is located above the metal disc 41, the electrostatic field can only spread downwards, forming a cone-like area in which the moon dust is attracted to the metal pellets 43. By adjusting the output voltage of the voltage generator 2, the intensity and the range of the electrostatic field can be changed, thereby realizing the selective collection of the moon dust with different particle sizes or different areas. The whole dust collecting device is turned over by operating the insulating handle 1, so that the insulating shielding cover 3 is obliquely upwards, the inlet of the sampling container 52 is upwards, the electric valve 53 is opened, the voltage generator 2 is closed to stop supplying power to the metal disc 41, the electrostatic field disappears, the piezoelectric ceramic 6 is used for applying high-frequency low-amplitude vibration, and the moon dust which is electrostatically adsorbed on the metal balls 43 falls into the sampling container 52 under excitation, so that the moon dust is collected.
When the dust collecting device collects moon dust, the insulating handle 1 needs to be bent, so that the handheld operation can be facilitated, and after the dust collecting device finishes working, the insulating handle 1 needs to be straight, so that the transportation is facilitated.
