Example Embodiment

[0024] The present invention will be described in detail below with reference to the drawings and embodiments.

[0025] The working principle of the spraying device of the present invention is as follows:

[0026] Such as figure 1 As shown, in the present invention, one short rod 7 of the spherical electric field detector 12 is connected to the motor through the screw 5, and the other short rod 7 is connected to the bearing 6 through the screw 5. When the motor 11 is started, the electric field detector 12 is short The rod 7 rotates as a shaft. The spray gun 2 is fixed on the mechanical arm 1, and the mechanical arm 1 can drive the spray gun 2 along the direction of the short rod 7 of the electric field detector 12 to make a uniform periodic movement at a fixed height. The center of the opening 9 of the homogenization plate 3 and the center of the sphere of the electric field detector 12 are on the same vertical line and perpendicular to the bottom plate 13. When the spray gun 2 ...

Abstract

The invention provides a spraying apparatus for highly uniform coating of a space electric field detector. The apparatus can realize highly uniform spraying of the surface coating of the electric field detector, and includes a spraying gun, a mechanical arm, a homogenization plate, a support bar, a bearing (6), a bearing mounting support, a motor, a motor mounting support and a baseboard; and the homogenization plate is arranged between the spraying gun and the electric field detector, and the shape of the opening of the homogenization plate is arranged to make the spraying gun uniformly spray the coating on the electric field detector. The structure of the spraying apparatus is simple and can be easily realized; and the concentration of the coating, the height of the spraying gun, the discharging speed of the spraying gun, a distance between the homogenization plate and the spraying gun, and a distance between the homogenization plate and the electric field detector can be fixed, and the surface spraying uniformity of the electric field detector can be guaranteed by changing the shape of the opening of the homogenization plate, so the spraying apparatus has the advantages of stable process, good repeatability and high quality coating, and is also suitable for the coating spraying of other crafts with rotational symmetry.

Description

technical field [0001] The invention relates to the field of spacecraft spraying technology, in particular to a spraying device for highly uniform coating of a space electric field detector. Background technique [0002] Space electric field measurement can provide accurate basic data and background for geophysical field research, earthquake monitoring, radio wave propagation, thunderstorm monitoring and other application fields, and improve the monitoring, early warning and evaluation capabilities of major natural disasters.
