Description

Booster suitable for photovoltaic tracking system and photovoltaic tracking system Technical Field The utility model relates to the technical field of photovoltaic tracking, in particular to a booster suitable for a photovoltaic tracking system and the photovoltaic tracking system. Background Along with global climate change, the demand for renewable energy sources and policy support of a plurality of countries, in recent years, the development and progress of photovoltaic power generation technology are continuously advanced, and the market of photovoltaic power generation is rapidly growing, wherein photovoltaic power generation is a technology for directly converting light energy into electric energy by utilizing the photovoltaic effect of a semiconductor interface through a photovoltaic panel, a controller and an inverter. The photovoltaic tracking system also continuously develops along with the photovoltaic power generation technology, the photovoltaic tracking system utilizes an automatic tracking system to lead sunlight to directly irradiate the photovoltaic array (namely the photovoltaic panel) through tracking the movement of the sun, and the received solar radiation quantity is increased, so that the power generation efficiency is improved, and the photovoltaic panel can rotate around the shaft under the support of the photovoltaic bracket along with the movement of the sun in the process of tracking the movement of the sun by utilizing the automatic tracking system. The rotating shaft of the photovoltaic panel is generally horizontally arranged, and in the process of driving the photovoltaic panel to rotate by using a power source (such as a motor), the first condition can occur that the gravity center of the photovoltaic panel moves from a high position to a low position, at the moment, the moment output by the power source is usually used for keeping the photovoltaic panel from freely rotating, namely, the moment is used for overcoming the influence of gravity, and the second condition can occur that the gravity center of the photovoltaic panel moves from a low position to a high position, at the moment, the moment output by the power source is required to overcome the action of gravity and the photovoltaic panel is required to be driven to move. In the two situations, when the gravity center of the photovoltaic plate and the central axis of the rotating shaft are positioned at the same horizontal position, the gravity influence of the photovoltaic plate is the largest. Therefore, when the power source is selected to drive the load driven by the transmission shaft which is not vertically arranged to rotate around the shaft, the power source is selected by considering the situation that the output moment of the power source can meet the condition that the gravity center of the load is positioned at the same horizontal position of the central axis of the rotation shaft, and when the load rotates around the shaft, the power of the power source is interference, so that the cost is increased. In order to solve the problem, it is also proposed to use a spring to assist a power source, and it is known that the spring cannot be stretched infinitely, and at the same time, under the condition that the elastic coefficient of the spring is set, the larger the elastic force fed back by the spring is along with the increase of the deformation of the spring, that is, the elastic force of the spring is in direct proportion to the deformation, so that the angle that the rotating shaft drives the load to rotate is limited, and therefore, the problem that the photovoltaic panel tracking work cannot be adapted is needed to be solved at present.
