Angle fine tuning device used for tracking small angular variation

Abstract

The invention discloses an angle fine tuning device used for tracking small angular variation. The angle fine tuning device comprises a shell with sliding rails at two sides and a hole respectively at the front and back ends, a first articulated shaft transversely penetrating through the sliding rails at the two sides and having a threaded hole in the middle, a second articulated shaft articulated with the first articulated shaft through an articulation piece, and a rotating member fixed at the upper end of the second articulated shaft, wherein one end of the rotating member is articulated with one end of the shell; a motor is fixedly arranged on a worm gear reducer and is arranged at the other end of the shell; a screw rod permeates through the bearing in the holes at the front and back ends of the shell and the threaded hole in the middle of the articulated shaft, and the output shaft of the worm gear reducer is connected through a shaft coupler; the motor rotates to drive the screw rod to rotate; the screw rod drives the first articulated shaft to move along the sliding rails; the rotating member rotates around the articulated place at one end of the shell; and an inclination angle dial can display a rotated inclination angle. The angle fine tuning device used for tracking the small angular variation can fine-tune the rotating member between 0 degree and 90 degrees, has a simple structure, runs steadily and is capable of reading an angle instantly.

Description

technical field [0001] The invention relates to the technical field of tracking, in particular to an angle fine-tuning device for tracking small angle changes, which can be used to track various small angle changes. Background technique [0002] In tracking technology, small angle tracking is often required. For example, the tracking of the solar declination angle in the photovoltaic power generation device only changes about 0.26 degrees per day. The traditional tracking angle of the gear pair driven by the motor often fails to meet the accuracy requirements, and the cost of the precise gear pair transmission system is too high. Converting small-angle circular changes into distance changes can often have a magnifying effect, which is of great help in solving small-angle tracking. Contents of the invention [0003] In order to solve the above-mentioned shortcomings of the prior art, the object of the present invention is to provide an angle fine-tuning device for trackin...
