Inclined single-shaft self-adaptive sun tracker for photovoltaic power generation

Abstract

The invention relates to an inclined single-shaft self-adaptive sun tracker for photovoltaic power generation. The inclined single-shaft self-adaptive sun tracker is characterized in that: a power output shaft of a speed reducer fixedly arranged on the top of a front upright is connected with the front end of a front shaft tube, the rear end of the front shaft tube is connected with the front part of a connecting shaft, and the rear part of the connecting shaft is fitted in the hole of a bearing pedestal and extended out of the bearing pedestal to be connected with a rear shaft tube; crossbeams are fixedly arranged on both sides of the front and the rear shaft tubes, and vertical beams are fitted on the crossbeams through heel blocks; the top of an A-shaped rear support is fixedly arranged on the bottom of the bearing pedestal; limit bars are symmetrically arranged on both sides of the outer surface of the bearing pedestal, and a limit block is arranged on the front part of the rear shaft tube; the axial central lines of the front and the rear shaft tubes are inclined at 20 to 35 degrees relative to the horizontal line; and the vertical central line of the rear support is perpendicular to the axial central lines of the front and the rear shaft tubes. The inclined single-shaft self-adaptive sun tracker has the advantages of small starting torque, high stability and high reliability, and greatly increases the generating capacity of a solar panel; all the main parts are made of high-quality steel products and undergo hot galvanizing and other processes, and thereby the service life and the corrosion resistance of the inclined single-shaft self-adaptive sun tracker are guaranteed.

Description

Technical field: [0001] The invention relates to a solar device, in particular to an oblique single-axis self-adaptive solar tracking device for photovoltaic power generation. Background technique: [0002] At present, the use of solar power generation has become an important method of new energy utilization. The solar photovoltaic module array is the main device to realize photoelectric conversion. It is related to efficiency and directly affects the performance, so the installation method of solar photovoltaic module array has a great influence on the efficiency of solar power generation system; [0003] Traditionally used in photovoltaic power generation devices, the sun shines on a fixed flat-panel solar panel tilted at a certain angle. The photovoltaic power generation device with this structure has low power generation efficiency; in order to solve this problem, an automatic sun tracking system came into being. Adopting the sun automatic tracking system can ensure tha...
