Embodiment Construction

[0009] Referring to the accompanying drawings, the embodiment includes a clock 1, a motor drive mechanism, and an astronomical instrument installation platform 6 that can rotate 360°.

[0010] The reduction motor 5 in the motor drive mechanism has two gear boxes before and after, and the motor is located in the middle. In the embodiment, the reduction motor 5 is installed horizontally. Since the rotating shaft of the astronomical instrument installation platform 6 is vertical, the output shaft of the rear gear box 8 is connected with the rotating shaft of the astronomical instrument installation platform 6 through a 90 ° output gearbox. According to the needs of space layout during specific implementation, if the reduction motor 5 is installed vertically, the output shaft of the rear gearbox can be directly connected with the rotating shaft of the astronomical instrument installation platform 6 .

[0011] Clock 1 is arranged opposite to the rotating shaft of front gear case 9,...

Abstract

The invention discloses an astronomical instrument azimuth tracking device comprising a clock, a motor driving mechanism and an astronomical instrument mounting platform capable of rotating by 360 degrees, wherein a deceleration motor in the motor driving mechanism is provided with a front gear case and a rear gear case; the output shaft of the rear gear case is connected with the spindle of the astronomical instrument mounting platform; the speed ratio of the spindle of the front gear case to the spindle of the astronomical instrument mounting platform is 24:1; the clock is arranged oppositely to the spindle of the front gear case; the spindle of a clock pointer is opposite to the spindle of the front gear case; the spindle of the front gear case is sheathed with one pointer; the front end of the pointer is provided with a trough-type infrared position sensor; the minute hand of the clock is shaded in the trough of the sensor; and the infrared position sensor controls the deceleration motor to rotate and stop by the control circuit. When the minute hand of the clock exceeds the infrared position sensor, the motor rotates to follow up and synchronously rotate with the clock, the astronomical instrument mounting platform is dragged to operate at the speed of 24 hours / turn, and the astronomical instrument azimuth is kept constant. The astronomical instrument azimuth tracking device has the advantage of simple structure and is accurate in tracking.

Description

technical field [0001] The invention relates to an attitude control device of an astronomical instrument, which is an azimuth tracking device. Background technique [0002] Observing planets with astronomical telescopes requires accurate positioning, and the specified celestial body cannot be observed if the azimuth angle changes slightly. Due to the rotation of the earth, the azimuth angle changes and needs to be constantly adjusted. Today's astronomical telescopes in large observatories are controlled by computers, with complicated mechanisms and high costs, and are not suitable for some small telescopes. Contents of the invention [0003] The object of the present invention is to provide an azimuth tracking device with high precision, low cost and simple structure, so as to be convenient to use. [0004] The solution of the present invention is: the azimuth tracking device for astronomical instruments, including a clock, a motor drive mechanism, and an astronomical in...
