Ultra-compact and high-stability double-layer main body structure of optical remote sensor

Abstract

The invention discloses an ultra-compact and high-stability double-layer main body structure of an optical remote sensor. The double-layer main body structure comprises a composite panel, a main bodybase, cover plates, a bottom plate, an outer cover, a light shield assembly, vibration isolators and fire work locks. The main body base and the outer cover are connected to the upper and lower planesof the composite panel respectively; the main body base is of a frame structure, the side face is provided with reinforcing rib structures shaped like a Chinese character 'mi', the cover plates are connected between the reinforcing rib structures, the bottom is connected with the bottom plate, and thus a sealed space is formed inside; the four fire work locks are symmetrically connected to a bottom frame of the main body base, the vibration isolators are connected to the four corners of a lower panel of the composite panel, and the remote sensor is connected with a satellite capsule plate through the fire work locks and the vibration isolators; heating sheets are pasted on the surfaces of the cover plates, the bottom plate and the outer cover, and temperature control over the heating sheets is conducted by a temperature controller so that the temperature in the main body base and the outer cover can be 20+ / -3 DEG C.

Description

technical field [0001] The invention relates to an ultra-compact and highly stable double-layer main body structure of an optical remote sensor, which belongs to the field of space optics technology and can be directly applied to the layout or configuration design of the main body of a space remote sensor. Background technique [0002] With the development of science and technology, the performance requirements of space optical remote sensors are getting higher and higher, and their functions are gradually diversified, which makes some remote sensors increase in size, quality and complex structure. [0003] The main structural support form of the traditional aerospace optical remote sensor is generally a single-layer flat plate installed on the satellite cabin, and all the opto-mechanical components, electronic equipment and other auxiliary equipment (such as outer cover and hood, etc.) of the remote sensor are installed on this flat plate. Due to the irregular layout of opt...

AI Technical Summary

Problems solved by technology

Due to the irregular shape of the optical-mechanical components and the large number of electronic devices with different shapes, the main body of the remote sensor has a large size and occupies the space of the satellite payload cabin.

The traditional satellite layout form is that the satellite distributes several loads on the ground, the lateral size of the load increases, the number of remote sensors carried by the satellite decreases, and the functions are limited.
