Sunlight double-axis tracking device

Abstract

The invention discloses a sunlight double-axis tracking device, which comprises a light gathering solar photovoltaic module, a photovoltaic module mounting bracket, a fixing upright post, a controller, a pitching adjustment mechanism and a horizontal adjustment mechanism, wherein the pitching adjustment mechanism comprises a main shaft and a driving device; the main shaft can rotate around a central axis of the pitching adjustment mechanism at an angle of 90 degrees and can be used for correspondingly adjusting the pitching angle of the light gathering solar photovoltaic module at the same time during rotating; the driving device is used for driving the main shaft; the horizontal adjustment mechanism comprises a rotary upright post, a driving mechanism and a rotating table; the rotary upright post can rotate around the central axis of the horizontal adjustment mechanism on the horizontal plane at the angle of 180 degrees and can be used for correspondingly adjusting the azimuth angle of the light gathering solar photovoltaic module at the same time during rotating; the driving mechanism can be used for driving the rotary upright post; and the rotating table synchronously rotates along with the rotary upright post. 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 fully utilizing power generation efficiency of the light gathering solar photovoltaic module, and various defects existing in the conventional light induction tracking system are effectively solved.

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] Tracking sunlight can allow solar photovoltaic systems to generate more power. Many solar equipment companies are competing to launch various solar tracking devices, including single-axis tracking, dual-axis tracking, and disc type. 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,...
