Disc type sample switching system

Abstract

The invention provides a disc type sample switching system. The disc type sample switching system comprises a shielding box cover, a sample mounting disc and a shielding box body which are coaxially arranged in sequence, one side, facing the shielding box cover, of the sample mounting disc is provided with a plurality of sample mounting areas which are distributed in an annular array; a first shielding reed is arranged on the peripheral edge of the sample mounting area; an electromagnetic radiation opening is formed in the shielding box cover; the peripheral edge of the electromagnetic radiation port is provided with a second shielding reed which can be plugged with the first shielding reed in a matching manner; the peripheral edge of the shielding box cover is provided with a third shielding reed; one end, facing the shielding box cover, of the shielding box body is provided with a fourth shielding reed which can be matched and inserted with the third shielding reed; and a first driving mechanism and a second driving mechanism are arranged in the shielding box body. The sample mounting plate is driven by the first driving mechanism to rotate, so that the test samples mounted on the sample mounting areas are switched, the test samples do not need to be manually replaced, and different electromagnetic wave powers required by tests of different test samples can be considered at the same time.

Description

technical field [0001] The present application relates to the technical field of special ground tests, and in particular to a disc-type sample switching system. Background technique [0002] A large number of multi-layer heat insulation components (MLI) are generally laid on the surface of the spacecraft, and the multi-layer heat insulation components are generally composed of several layers of aluminized film and spacer layers (generally up to 5 to 20 layers). The base material is generally polyester film, the spacer layer is generally polyester thread, flame retardant thread, etc., and the base material of the outer film is generally polyimide material. At the same time, in order to enhance its surface adaptability, it is also carburized on the surface, ITO plated, etc. Craft multilayer insulation components. Under the coupling effect of vacuum and strong electromagnetic field, secondary electron multiplication effect and low-pressure discharge may occur on the surface of...

Problems solved by technology

[0003]Because the process of opening the device (vacuum background establishment) can take several hours, it is difficult to manually replace the effector during the test, and when placing multiple effectors at the same time, It is difficult to take into account the different electromagnetic wave powers required for different effector tests. When using traditional vacuum motors for transmission, it is difficult for the corresponding equipment to survive in complex electromagnetic environments.
