Problems solved by technology

However, for movable telescopes, it is often just to install a protective cover or use tarpaulin to prevent dust and rainwater from entering the system, which is inconvenient to use and poor in aesthetics.
There is currently no special device for its protection

Embodiment Construction

[0018] The structure, working principle and working process of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] figure 1 is an axonometric drawing of the roller shutter guard for the telescope's main tube, drawn to actual scale, figure 2 This is a schematic diagram of the rolling shutter protective device used for the main lens barrel of the telescope. In order to show the structural features more clearly, the smaller structure has been enlarged. image 3 Expand the schematic for the tarpaulin. The figure includes an upper cover plate 2, a handle 5, four sliding bearings 6, two reels 7, a cloth 8, four supports 9 and a main lens barrel 10; the two reels 7 pass through the four sliding bearings 6 is installed on the support 9; there is a light hole in the middle of the veil 8, and the two ends are distributed and connected to the two reels 7; the handle 5 can be inserted into the two reels 7 to drive the reels to r...

Abstract

The invention provides a shutter-type protective device used for a primary lens cone of a telescope, and belongs to the technical field of researches of optical measurement equipment. The shutter-type protective device comprises a guide rail sealing structure and a shutter-type execution structure, the guide rail sealing structure comprises a lower guide rail, an upper cover plate, a U-type sealing strip and a B-type sealing strip, and the shutter-type execution structure comprises four supports, two reels, a shielding cloth and a handle. By rotation of the handle, the device can be matched with the work state of the telescope to be opened and closed and basic dustproof and waterproof functions are achieved in a closed state.

Description

technical field [0001] The invention relates to a rolling shutter type protective device for a main lens barrel of a telescope, and belongs to the technical field of optical measurement equipment development. Background technique [0002] Telescopes are precision optical devices, but their working environments are often on plateaus or in the wild. Harsh natural conditions such as dust and rainfall can easily cause damage and pollution to the telescope window and even the primary mirror, seriously affecting the performance of the overall system. [0003] To solve this problem, domes are usually built for ground-based telescopes to protect the system. However, for movable telescopes, it is often only to install a protective cover or use a tarpaulin to prevent dust and rainwater from entering the system, which is inconvenient to use and poor in appearance. Also do not have a kind of special device for its protection at present. Contents of the invention [0004] The purpos...
