Light-weight slave astronomical telescope dome applicable to Antarctic

Abstract

The lightweight astronomical telescope dome suitable for Antarctica is equipped with the lower roof room and the upper dome on the upper part, which is characterized by the light quality from the dynamic astronomical telescope dome directly on the astronomical telescope;Both the upper dome adopt a cable structure, which includes the skeleton composed of a metal rod, and the tensor covering the skeleton;, The roundtage skeleton is covered with a tensor film; the lower dome is fixed on the red meridian shaft of the astronomical telescope, turning with the red meridian axis;The mussel shell structure skeleton is formed; the mussel shell structure skeleton is covered with a tensor film to form a hemispherical shape; the upper dome is fixed on the rack of the astronomical telescope, and it rotates with the astronomical telescope lens barrel.The present invention can adapt to the harsh environment of the polar position; convenient and simple in pretending; low temperature resistance; anti -ultraviolet radiation; light weight.

Description

technical field [0001] The invention belongs to an astronomical telescope dome, in particular to a light driven astronomical telescope dome suitable for the Antarctic. Background technique [0002] "Dome" usually has two meanings in a broad sense and a narrow sense. In a broad sense, a dome refers to a "dome room". Adverse effects of changes on observations. The generalized "dome" includes the "lower dome" or "lower dome" with a lower cylindrical structure, and the "dome" in the narrow sense that is arranged on the upper part of the dome chamber and can be rotated and opened ( Also called "upper hemispheric dome" or "upper dome"). "Dome" in the subject of the present invention means a dome in a broad sense. [0003] The dome room is usually a cylindrical structure of a fixed building, and the top is a hemispherical shell that can be rotated in azimuth—the upper dome. There are two long and narrow movable skylights on the upper dome, which can be separated in the horizont...

AI Technical Summary

Problems solved by technology

[0004]The Antarctic ice dome Dome A is located in the cold Antarctica, with an altitude of 4093m. The working conditions there are harsh, and now only half a month of the year is suitable for human work. Therefore, the existing telescope The technology of the dome is relatively complicated, and it is generally a fixed building, which cannot be installed in a short period of time. It is very difficult to build in the Antarctic region; in addition, the Antarctic region sometimes has a lot of snowfall, and the accumulation of heavy snow on the dome has the risk of crushing the dome ;Due to the reflection of the large area of ​​snow, the materials used to construct the dome are also exposed to ultraviolet radiation higher than that of ordinary areas

Therefore, the existing general astronomical telescope domes cannot meet the requirements of installation and use under Antarctic conditions.

The needs of scientific research and development in the Antarctic region require an astronomical telescope dome suitable for installation and use under Antarctic conditions; and there is no suitable technical solution in the prior art
