Technical Field

[0001] The invention relates to the technical field of mirror cleaning, and in particular provides a mirror cleaning device. Background Art

[0002] Space reflectors are the core components of space remote sensing optical payloads. During operation, the reflector surface is used to reflect light. When the reflector surface is contaminated by dust and other particles, it will have a significant impact on the system, such as affecting system efficiency and introducing stray light. Usually, the reflector surface is cleaned before assembly to remove particulate contaminants generated by ground storage and transportation.

[0003] At present, the cleaning of reflectors mainly focuses on contact cleaning. For example, the Chinese patent application publication number is CN106405786A, the publication date is February 15, 2017, and the patent name is "Adjustable cleaning and sealing device for large-aperture reflectors". Another example is the Chinese patent application publication number is CN109865688A, the publication date is June 11, 2019, and the patent name is "A solar thermal power generation reflector cleaning system". Both are contact cleaning devices. Contact cleaning has many disadvantages. For example, it may cause scratches on the surface of the reflector, leave "watermarks" of the cleaning agent, and damage the film layer on the surface of the reflector. Summary of the invention

[0014] Compared with the prior art, the present invention can achieve the following beneficial effects: The cleaning device of the present invention uses high-pressure nitrogen to blow up dust on the mirror surface, and then uses a suction pipe to collect the blown dust. The dust removal process does not contact the mirror surface, does not damage the mirror surface, and the nitrogen does not leave water marks.

[0022] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0023] like Figure 1 and Figure 2 As shown, the present invention provides a mirror cleaning device, comprising: The mounting frame 2, the dust collecting plate 3, the dirt suction pipe 4, the air blowing pipe 5, the first fixing frame 6, the handrail 7 and the second fixing frame 8. The air blowing pipe 5 is mounted on the mounting frame 2 through a plurality of second fixing frames 8, and the dirt suction pipe 4 is mounted on the mounting frame 2 through a plurality of first fixing frames 6. One end of the air blowing pipe 5 faces the mirror surface 1 to be cleaned, and the other end is connected to the gas source, and the gas source can provide high-pressure gas for blowing up dust. In the embodiment of the present invention, high-pressure nitrogen is selected as the gas source, and the pressure of the high-pressure nitrogen blown out from the air blowing pipe 5 is 0.3MPa to 0.5MPa. In the embodiment of the present invention, the air blowing pipe 5 is arranged below the dirt suction pipe 4, specifically: the air blowing pipe 5 is arranged on the lower surface of the mounting frame 2, that is, the side close to the mirror surface 1, and the dirt suction pipe 4 is arranged on the upper surface of the mounting frame 2, that is, the side away from the mirror surface 1.

[0024] The end of the dirt suction pipe 4 close to the mirror surface 1 is called the front end, and the front end is connected to a dirt suction head. The shape of the dirt suction head is not limited, but the size of the dirt suction head is much larger than the size of the dirt suction pipe 4. In the embodiment of the present invention, the dirt suction head is set in a rectangular shape, and its long side is perpendicular to the dirt suction pipe 4. The dirt suction head can expand the dirt suction area and improve the dirt suction efficiency. The tail end of the dirt suction pipe 4 can be connected to a dust collection container according to demand to collect dust.

[0025] A dust collecting plate 3 is installed at the front end of the suction head, and the plane where the dust collecting plate 3 is located is perpendicular to the mirror surface 1. The dust collecting plate 3 can block the airflow blown out by the air blowing pipe 5, reduce the diffusion degree of the blown dust, increase the degree of dust collection, and further improve the dust removal efficiency.

[0026] There are two handrails 7, which are respectively arranged at both ends of the mounting frame 2. The user can hold the mirror cleaning device by the handrails 7 and move it relative to the mirror surface 1 for easy cleaning.

[0027] In particular, the length of the mounting frame 2 can be set to be greater than the diameter of the mirror surface 1, so as to facilitate the movement of the mirror surface cleaning device.

[0028] During operation, the gas source provides high-pressure nitrogen, which is discharged from the blowing pipe 5 to blow away the dust attached to the mirror surface 1. The dust blown by the blowing pipe 5 can be collected through the suction pipe 4 to achieve dust removal of the mirror surface 1.

[0029] Although the embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and cannot be understood as limiting the present invention. Those skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
