Abstract

The foldable and retractable dust-proof device for large-caliber horizon telescopes belongs to the field of dust-proof technology for the main mirror of large-caliber telescopes; it solves the problem that when the cover plates of large-caliber telescopes shrink, dust and particles on adjacent cover plates may fall into the telescope , a technical problem that affects the dust-proof effect; the stepper motor of this device drives the drive shaft to rotate, and the power is transmitted to the lead screws on both sides through two bevel gears, so that the lead screws rotate, and the lead screw slides along the lead screw The direction of the linear movement drives the sealing plate, the elastic bellows hinge and the elastic bellows skeleton to make linear movements at the same time, so as to realize the shrinkage and opening of the dustproof device; Foldable and shrinkable dust-proof device, the foldable cover is made of polyester fiber hinge and PVC material skeleton, the hinge and skeleton are connected together by thermal fusion, which realizes no wind load and does not damage the balance of the telescope. It has the characteristics of simple structure, good sealing, light weight and long life.

Description

technical field [0001] The invention belongs to the technical field of dustproofing of the main mirror of a large-scale telescope, and in particular relates to a foldable and shrinkable dustproofing device for a large-caliber horizon telescope. Background technique [0002] The site of the telescope is generally located in the Gobi or desert area, where there are many windy sand and dust. With the accumulation of time, the sand and dust are easy to adhere to the surface of the primary mirror, thus contaminating the mirror surface. Although cleaning technology is used for regular cleaning, the number of cleanings is too much Not only will the reflectivity decrease, but the steps are complicated and the cost is high. In order to prevent foreign matter accidentally falling into the telescope and causing permanent damage or damage to the telescope's main reflector, it is necessary to design a separate dust-proof component to protect the telescope's main reflector. [0003] At p...
