Abstract

The invention discloses a sunlight device for automatically tracking an inclination angle of a solar panel in photovoltaic generation. The sunlight device comprises a bracket and a rotating shaft installed on the bracket; a photovoltaic solar panel is installed on the rotating shaft; a closed cavity with an oil wiping adjustment hole is arranged at the lower end of the photovoltaic solar panel on the bracket; liquid is filled in the lower part of the closed cavity, and the level of the liquid is higher than that of the liquid at an outlet of the closed cavity; gas is filled in an upper part of the closed cavity; a piston is arranged at the outlet position of the closed cavity; a lever is installed on the rotating shaft; and one end of the lever is hinged with the piston while the other end of the lever is contacted with the back of the photovoltaic solar panel. In the invention, the closed cavity is adjusted through the oil wiping adjustment hole so as to implement the adjustment of parameters such as thrust, displacement and the like.

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 at an 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 methods for human beings 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 the ways of its wide application. However, since the size and direction of sunlight change periodically with time, in order to improve the utilization rate of solar energy, the most common way is to equip an automatic tracking system with a two-dimensional direction. Although the automatic control technology is developed to today, it is not difficult to realize autom...
