The invention discloses a center hole opening coaxial sleeve type synchronous lifting dome cover. The dome cover comprises a sleeve type lifting assembly, a dome cover, a cover plate and a push-pull driving device. The sleeve type lifting assembly is driven by a driving mechanism to do telescopic motion in the vertical direction to form a cylindrical closed space. The dome cover is fixedly connected to the top end of the sleeve type lifting assembly and moves along with the sleeve type lifting assembly. The dome cover is a mounting carrier of the push-pull driving device; the dome cover is provided with a circular middle hole, the middle hole provides an observation visual angle for the telescope, the two semicircular cover plates are horizontally and symmetrically installed in the push-pull driving device, the push-pull driving device drives the cover plates to open or close the middle hole of the dome cover, and when the middle hole is closed, the cover plates generate turnover motion to seal the butt joint position. When the telescope is used for observation, the middle hole cover at the top of the dome cover is opened and then descends along with the telescopic sleeve to provide an unshielded observation environment for the telescope; and when observation is not performed, the telescopic sleeve is lifted and the middle hole cover is closed to form a closed environment to protect the telescope equipment.
本发明公开了一种中孔开合同轴套筒式同步升降圆顶罩,该圆顶罩包括套筒式升降组件、圆顶盖、盖板和推拉驱动装置;套筒式升降组件在驱动机构的驱动下沿竖直方向做伸缩运动,形成圆柱形的封闭空间,所述圆顶盖固定连接在套筒式升降组件的顶端随动,圆顶盖为推拉驱动装置的安装载体,圆顶盖具有一个圆形的中孔,中孔为望远镜提供观测视角,两块半圆形的盖板水平对称安装在推拉驱动装置中,推拉驱动装置驱动盖板打开或关闭圆顶盖的中孔,关闭中孔时盖板产生翻转运动使得对接处密封。望远镜观测时,圆顶罩顶部的中孔盖打开后随伸缩套筒共同降下,为望远镜提供无遮挡观测环境;不观测时,伸缩套筒升起后中孔盖关闭,形成封闭环境保护望远镜设备。
