Description

Technical Field

[0001] The present invention relates to the technical field of optical measurement, and particularly to an L-shaped waterproof seeing meter. Background Art

[0002] At present, most seeing meters on the market are of an open design and require an astronomical dome or a flat-top protection. Most of the turntable parts are designed with a two-dimensional vertical axis system, and the scanning and tracking of a plane or a spherical surface are realized by rotating two mutually perpendicular axes. Many small two-dimensional turntables, whether of an equatorial or horizontal design, require a lot of weights to balance the load. The drive part of many popular science-level two-dimensional turntables uses a stepper motor, and the rotation distance is calculated by the number of pulses of the stepper motor. For problems such as backlash and slippage, there will be problems with inaccurate pointing. The turntable is basically driven by a motor, and the electronic circuit components of the motor itself and the control part do not have waterproof capabilities. The turntable housing design is mainly to prevent external force contact or for safety protection and generally does not have waterproof capabilities. Many optical measurement systems use an open truss or a simple optical telescope. The front mask has two light-passing holes at a certain distance from each other. One is a hollow hole without any obstruction, and the other is a 1-2 angular spectroscope wedge. Such a design allows the same star to form two star images with a certain distance on the rear measurement camera after passing through the double holes. A series of images are obtained by high-frequency short exposure of the camera, and at the same time, the numerical value of the atmospheric stability, that is, the seeing value, is obtained through numerical calculation of the change in the distance between the two star images. The focusing device and the camera part working at the rear are both exposed. Before the outbreak of bad weather such as precipitation and sandstorms, it is necessary to manually or automatically close the dome to protect the turntable and the optical system from being affected by sandstorms and precipitation.

[0003] The two-dimensional turntables of common seeing monitors are mostly altazimuth or equatorial turntables, with a load-bearing capacity of no more than 50 kg. Whether it is an altazimuth or equatorial turntable, because the turntable itself is shaped like a "T", when a telescope (load) is mounted on one side, appropriate counterweights must be mounted on the other side according to the need for balance. This results in a relatively large design load-bearing index for the turntable, but the effective load-bearing capacity is not large. Most two-dimensional turntables do not have an encoder disk or a relative encoder disk, and manual intervention is required to find zero every time the device is powered off. In addition, the drive parts of many turntables are exposed more, and they have poor adaptability to relatively harsh weather and environments. A small amount of precipitation falling on the turntable may damage the turntable. For the mask part at the front end of the optical measurement system, the light wedge through-hole can prevent a little trace of precipitation, but no protection is taken for the hole in the other original optical path. This allows precipitation and dust to directly enter the interior of the optical system, affecting cleanliness and imaging; too much precipitation will directly cause short circuits and damage to the electronic control parts such as the focus adjustment and camera at the rear end. The existing design mainly protects the device by closing the external dome, and the seeing monitor itself does not have a special waterproof design, so it does not have the ability to resist rain and snow weather and environments as a whole.

[0004] Based on the above technical problems, those skilled in the art urgently need to develop an L-shaped waterproof seeing monitor with a simple and compact structure, a certain waterproof ability, the ability to adapt to relatively harsh weather and environments, and suitable for remote control and automated task execution.

[0052] In this embodiment, industrial-grade steel-plastic sealed bearings are used. The axial and radial bearing capacities of the two bearings are both greater than 300 kg. Considering easy transportation and lightweight design, the weight of each module is small, and the total bearing capacity of the support and drive parts can reach 80-100 kg.
