Problems solved by technology
[0004] However, considering that the multi-piece splicing lens cover device has high requirements for the coordinated drive and motion consistency of each lens cover, and its difficulty increases with the increase in the number of lens cover pieces, the electromechanical structure is used to realize the control. For the drive of the lens cover, the failure rate of each electronic component needs to be considered. Once the electric drive of a single lens cover fails, it will seriously affect the overall performance of the drive structure of the lens cover, and the potential failure rate is high.
[0005] In addition, the traditional large-aperture optical system lens cover is arranged on the optical system lens barrel, which is not conducive to the trimming of the overall structure of the large-aperture telescope optical system. The lens cover with a large windward area increases the wind load on the telescope during movement. Systemic Impact Risk

Embodiment Construction
[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0049] The core of the present invention is to provide a split-type protective cover. The lens cover device is arranged on the split-type protective cover, which can avoid the restriction of the lens cover design on the design of the large-aperture optical system to the greatest extent, and simplify the trimming and wind load of the telescope system. impact on the system.

The invention discloses a split protective cover which comprises a base, a right door of the protective cover and a left door of the protective cover, the right door and the left door are split and are both rotationally arranged on the base, the right door is provided with a right lens cover mechanism, and the left door is provided with a left lens cover mechanism; and when the right door and theleft door are closed, the right lens cover mechanism and the left lens cover mechanism are closed and are in sealed connection with a telescope lens cone. The right lens cover mechanism and the left lens cover mechanism used for sealing protection for the telescope lens cone are arranged on the right door and the left door of the protective cover respectively, a structure split from the telescopeis realized, the problem that a lens cover limits design of a large-aperture optical system is avoided, and influence of balance and wind load of a telescope system on the system is reduced; and the lens cover only comprises the right lens cover mechanism and the left lens cover mechanism, the fault rate of the lens cover mechanism is reduced, and a motion mechanism is more reliable and more stable.
Description
technical field [0001] The invention relates to the technical field of telescopes, and more specifically, to a split-type protective cover. Background technique [0002] The split shield and fixed station dome are the most commonly used protection methods for large-aperture telescope systems. Compared with the fixed station dome, which has a longer construction period, high construction costs and fixed single protection for the telescope system, the The open protective cover can be used for safety protection during the installation, adjustment, transportation and transition test of the mobile telescope. Sometimes it can also be used in conjunction with simple infrastructure conditions to replace the dome to achieve simple observation protection for the telescope, which simplifies the difficulty and requirements of infrastructure construction. The construction period is shortened. Therefore, the split protective cover is more and more commonly used in the equipment protectio...
