Sunlight double-axis tracking device

Abstract

The invention discloses a sunlight double-axis tracking device, which comprises a supporting upright post, a solar photovoltaic plate, a photovoltaic plate mounting bracket, a pitching adjustment mechanism, a horizontal adjustment mechanism and a control system, wherein the solar photovoltaic plate is positioned above the supporting upright post; the control system is used for comprehensively controlling the pitching adjustment mechanism and the horizontal adjustment mechanism according to a previously set control mode; the pitching adjustment mechanism comprises a pitching angle servo motor and a rotating main shaft; the rotating main shaft intermittently rotates around a central axis of the pitching adjustment mechanism and can be used for intermittently adjusting the pitching angle of the solar photovoltaic plate in a rotation process; the horizontal adjustment mechanism comprises a horizontal rotating table, a rotary connecting piece, a main shaft sleeve and an azimuth angle servo motor; the main shaft sleeve synchronously rotate along with the rotary connecting piece and is used for correspondingly performing continuous adjustment on the azimuth angle of the solar photovoltaic plate; and the azimuth angle servo motor is used for driving the horizontal rotating table. The device has the advantages of simple structure, rational design, simplicity and convenience in use and operation, low working cost, reliable performance, high operation accuracy and capability of greatly reducing operation cost while guaranteeing tracking accuracy and equipment reliability.

Description

technical field [0001] The invention belongs to the technical field of sunlight automatic tracking, and in particular relates to a sunlight dual-axis tracking device. Background technique [0002] Most of the traditional solar tracking systems use light sensing systems, and traditional solar tracking systems generally use a single-pillar structure, and some of them use a disc structure. In the actual use process, the light sensing system not only has low precision; but also because the light sensing system will keep looking for light sources when there are clouds, resulting in high power consumption; at the same time, when the clouds leave, the traditional sunlight tracking system needs a certain amount of time It takes time to adjust and track, so while affecting the power generation, it also increases a lot of power consumption. To sum up, the traditional solar tracking system has defects and deficiencies such as low precision, high cost, large power consumption, and smal...
