Array linkage type solar energy two-degree-of-freedom tracking system

Abstract

An array linkage type solar energy two-degree-of-freedom tracking system comprises a supporting mechanism, a tracking mechanism, a linkage mechanism, and a driving device, wherein the supporting mechanism supports a battery panel tray by using a cardan joint and a vertical shaft; the tracking mechanism is connected to a transmission gear by using the linkage mechanism, the driving device is connected to the linkage mechanism, the linkage mechanism is connected to a tracking crank by using a linkage diverter and a linkage connecting rod, and performs successive disjunction distribution and winding cascading on two types of linkage nodes a and b along an azimuth angle (or altitude angle) linkage direction by using a steel wire rope, to implement power transmission between nodes in an array. According to the present invention, the quantity of driving devices and the quantity of sensors are reduced, a structure is relatively simple, and array linkage type solar energy two-degree-of-freedom tracking is implemented with low costs, so that not only a solar energy utilization ratio is improved, but also a geography adaptive capacity is enhanced, and array expansion is simpler and more convenient; and the quantity of battery panel components carried by a single tracking device is greater, and an area is larger.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to an array linkage solar two-degree-of-freedom tracking system for a photovoltaic power station. Background technique [0002] Due to the characteristics of cleanliness, renewability, safety and universality, solar energy is developing into an important part of green energy all over the world. The most effective way to utilize solar energy is solar power generation, especially the use of solar energy for photovoltaic power generation. In the photovoltaic power generation system, if the lighting device of the solar panel can always be kept perpendicular to the incident light, that is, adding a solar tracking device, the solar energy can be collected to the maximum and the utilization rate of the solar energy can be improved. However, at present, most of the automatic sun tracking devices in solar photovoltaic power plants are single and independent, and each of them is equippe...
