Equatorial telescope bracket

Abstract

The invention relates to an equatorial telescope bracket which comprises a base, a hour angle mechanism and a deflection angle mechanism, wherein the hour angle mechanism is connected with the base and driven by a latitude regulating mechanism to rotate around a latitude shaft; the deflection angle mechanism is connected with the hour angle mechanism and manually regulated or driven by a hour angle driving mechanism to rotate around a hour angle shaft; the deflection angel mechanism is connected with a connecting lens cone support plate; the support plate can be manually regulated or driven by a deflection angle driving mechanism to rotate around a deflection angel shaft; an independent hour angle position detection mechanism and deflection angle position detection mechanism are respectively arranged in the hour angle mechanism and the deflection angle mechanism; the hour angle position detection mechanism and the deflection angle position detection mechanism are matched to form a dual encoder and connected with a control unit to form a closed-loop control system; and hour angle and deflection angle clutch mechanisms are arranged in the hour angle mechanism and the deflection angle mechanism. The equatorial telescope bracket provided by the invention has the advantages of simple and compact structure, convenience in assembly and maintenance, convenience in operation and high accuracy, has the manual and automatic regulating functions and can be widely applied to astronomy and other engineering fields which need to carry out angel measurement.

Description

technical field [0001] The invention relates to an equatorial mount, in particular to an equatorial mount bracket with an innovative structure. Background technique [0002] An equatorial mount is a common instrument for measuring angles. It is usually used in conjunction with astronomical telescopes for astronomical observations, and provides measurement scientific data for astronomical phenomena and astronomical research. Generally speaking, because the equatorial mount must make compound angle adjustments in three-dimensional space, its bracket must have high precision, so that the observation angle of the matching telescope can be accurately adjusted to achieve precise positioning of celestial bodies and real-time track. The existing equatorial mount brackets generally use the meshing mode of worm gear and worm to drive the operation. However, such brackets are usually only adjusted manually. The adjustment process takes a long time and the accuracy is low, so it is dif...

AI Technical Summary

Problems solved by technology

The existing equatorial mount bracket generally adopts the transmission mode of worm gear and worm gear meshing. However, this kind of bracket is generally only adjusted manually. The adjustment process takes a long time and has low precision, which is difficult to meet the needs of practical applications.

Some brackets are also adjusted by electric motors, but they cannot be rotated by hand. If the manual is used, the automatic star-finding function of celestial bodies cannot be realized, or the pointing accuracy of the brackets is very poor when rotating.
