The present invention discloses a solar tracking power generation device. The solar tracking power generation device comprises a fixed seat, a rotary seat, a photovoltaic panel assembly, a left hydraulic cylinder and a right hydraulic cylinder; the hydraulic rods of the left hydraulic cylinder and the right hydraulic cylinder can extend out or retreat when temperature changes; the rotary seat which rotates around a horizontal axis is arranged on the fixed seat; the photovoltaic panel assembly which rotates around a longitudinal axis is arranged on the rotary seat; the lower surface of the photovoltaic panel assembly is provided with the left hydraulic cylinder and the right hydraulic cylinder which are arranged along a longitudinal direction and are located at the left side and right side of the longitudinal axis respectively; and the end portions of the hydraulic rods of the left hydraulic cylinder and the right hydraulic cylinder are connected with the fixed seat through transmission components. According to the solar tracking power generation device of the invention, the thermal expansion of a liquid is used as a driving force, the non-gasification and incompressible characteristics of hydraulic oil enclosed in the hydraulic cylinders are ingeniously utilized, and therefore, the photovoltaic panel assembly can be pulled to rotate, the tracking of sunlight is realized, the photovoltaic panel assembly can always face the sun, and the utilization rate of the sunlight can be improved. The solar tracking power generation device of the invention is not required to be connected with an external power source, and therefore, the use costs of the solar tracking power generation device is low.
Description
technical field [0001] The invention belongs to the technical field of solar photovoltaic power generation, and in particular relates to a solar tracking power generation device. Background technique [0002] Today, as new energy is increasingly valued, both national policies and industrial trends indicate that there will be earth-shaking changes in the field of new energy. In the field of new energy, the solar photovoltaic power generation industry is the most popular and expected. [0003] Due to the rotation of the earth, compared with a solar photovoltaic power generation system at a fixed location, the sun rises and sets every day in the four seasons of the year, and the angle of the sun's illumination changes all the time. For the sun, the power generation efficiency will reach the best state. At present, the application of solar tracking system at home and abroad is mainly the design form of photosensitive sensor + motor or positioning + clock + motor. Due to the n...
