A space spiral unfolding exposure platform

Abstract

The invention relates to a space spiral unfolding exposure platform, which includes a telescopic drive device, a first telescopic column, a hollow shaft motor, a guide rail drive device, a spiral guide rail and a sample tray. The drive end of the telescopic drive device is connected to drive the first telescopic column to expand and contract, Each telescopic section of the first telescopic column is respectively equipped with a hollow shaft motor, which is connected with a sample tray and drives the sample tray to rotate around the first telescopic column; the spiral guide rail surrounds the outer peripheral side of the sample tray, and the guide rail drive device It is connected with the spiral guide rail and drives the spiral guide rail to expand or retract; wherein, when the telescopic drive device drives the first telescopic column to retract, the sample trays on each telescopic section are arranged circumferentially around the first telescopic column to form a cylindrical structure. The exposure platform of the present invention uses a lifting structure to lift and lift the petals of each sample tray in a cylindrical structure, so that the sample trays of the exposure platform are arranged in a spiral shape during the unfolding stage, ensuring sufficient exposure space.

Description

technical field [0001] The invention relates to the technical field of planetary scientific sampling and return, in particular to a space exposure platform with a spiral unfolding function. Background technique [0002] The collection of interplanetary dust particles is an important part of the space sampling return mission. The collection process of interplanetary dust particles is essentially the process of obtaining samples from different stars, which is an important expansion and mutual complement of the deep space sampling return mission. All countries have carried out the construction of interplanetary dust sampling platforms in the field of space exploration, and built various interplanetary dust sampling platforms. The major achievements of the Interplanetary Dust Sampling Platform are reflected in the returned dust samples and the scientific research results obtained from the extraction and analysis of these samples by planetary scientists. The collection and resea...

AI Technical Summary

Problems solved by technology

[0007] During the collection and exposure process of the collection plate, if the attitude adjustment is required, the attitude adjustment of the entire spacecraft is required, and it cannot be guaranteed that the collection plane collects dust particles at the angle where the interplanetary dust particle flux is the largest

[0008] The collection units of the collection plate are integrally connected, and there is no angle difference between the collection units, so it is impossible to count the difference in interplanetary dust particle flux caused by different angles
