Problems solved by technology

[0003] A high-precision two-dimensional tracking system is necessary for solar concentrators, but considering factors such as cost and actual effects, one-dimensional (azimuth) automatic tracking methods have to be used more in many large-scale photovoltaic power generation occasions, so that It reduces the utilization rate of solar energy

Abstract

The invention relates to an apparatus for automatically tracking sunlight in an inclination angle direction of a battery board in photovoltaic power generation, which comprises a photovoltaic panel mounted on a rotating shaft. The lower end of the photovoltaic panel is provided with an air-filled seal cavity, a piston is arranged at the outlet of the seal cavity and a lever is arranged on the rotating shaft. One end of the lever is articulated with the piston while the other end is contacted with the back surface of the battery board. In the invention, according to corresponding inherent law and characteristics between the changing period (one year) of inclination angle of the sun and the temperature (climate), ingeniously matched expansion on heating and contraction on cooling of gas in the seal cavity and horizontal component force of the photovoltaic panel fixed on the rotating shaft are utilized to form a push-pull type power source and the inclination angle of the photovoltaic panel can be adjusted directly by amplifying the displacement of the piston via the lever so as to realize two-dimensional automatic tracking of sunlight by the photovoltaic cell to achieve the purpose of improving the utilization rate of sunlight.

Description

Technical field [0001] The invention relates to a device for two-dimensional automatic tracking of sunlight in solar energy applications, in particular to a device for automatically tracking sunlight in the direction of the inclination angle of a battery panel in photovoltaic power generation. technical background [0002] The development and utilization of new energy represented by solar energy has become one of the effective ways for mankind to solve the energy crisis, and it has also become the basic energy decision of my country's sustainable development strategy. Solar photovoltaic power generation has become one of its widely used ways. However, as the size and direction of sunlight change periodically with time, in order to improve solar energy utilization, the most common way is to equip a two-dimensional direction automatic tracking system. Although in the development of automatic control technology to this day, it is not difficult to realize automatic tracking of sunli...
