Abstract

The embodiment of the invention provides a horizontal cross-shaped photovoltaic control device. The device comprises a rotor, a main transmission column and an auxiliary transmission column, the maintransmission column and the auxiliary transmission column are arranged in parallel, the rotor is erected over the main transmission column and the auxiliary transmission column, a photovoltaic assembly is laid on the rotor, and a transmission device rotating horizontally is arranged on the main transmission column and used for controlling the inclination angle between the rotor and the horizontalplane through horizontal rotation. The embodiment of the invention further provides a horizontal cross-shaped photovoltaic control system. The inclination angle of the photovoltaic assembly is controlled in a horizontal rotation mode of the transmission device. The horizontal rotating structure is not affected by pile foundation sinking, and the reliability and stability of the whole device are improved. The relation between the rotating speed of the transmission device and the rotating speed of a motor is simpler, control is easier, and the uniform rotating speed and constant power can be kept. The motor and the structure are well protected.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a horizontal cross photovoltaic control device and system. Background technique [0002] With the development of science and technology, more and more attention has been paid to the utilization of energy. The role of photovoltaic power generation technology in life is becoming more and more prominent. Photovoltaic power generation technology can convert light energy into electrical energy, making full use of the energy of nature. In order to make full use of the light energy, the position of the photovoltaic module needs to be adjusted, especially the photovoltaic module needs to be oriented toward the sunlight, so as to achieve a higher utilization rate of light energy. Based on this, a photovoltaic tracker is added to the current photovoltaic system. However, the cost of photovoltaic trackers is relatively high, and the control method is relatively complicated, s...
