Two-axis rotary automatic tracking solar device

Abstract

The invention relates to a dual-axis rotary automatic tracking solar energy device. The device is fixedly connected with a horizontal rotary reducer on the flange plate of the lower column, the flange plate at the lower end of the upper column is fixed on the flange plate of the power output shaft of the horizontal rotary reducer, and the flange plate at the upper end of the upper column is fixed with a connecting plate. The support beam shaft tube is equipped with a vertical rotary reducer in the middle of the support beam shaft tube, and bearing seats are respectively provided at both ends of the support beam shaft tube. The left and right power output shafts are connected, and the other ends of the rotating shaft tubes of a pair of brackets are respectively fitted into two bearing seats, and extend out of the two bearing seats to be fixed on the solar panel component brackets respectively; Rotation has the advantages of high tracking accuracy, strong rigidity of the whole machine, not easy to deform, low consumables, long life, not easy to produce lower deflection, good torque resistance, and convenient disassembly and assembly.

Description

Technical field: [0001] The invention relates to a solar device, in particular to a dual-axis rotary automatic tracking solar device. Background technique: [0002] Nowadays, using solar power to generate electricity has become an important method of new energy utilization. The solar photovoltaic module array is the main device to realize photoelectric conversion. It is related to the conversion efficiency and directly affects the performance. Therefore, the installation method of the solar photovoltaic module array has a great influence on the efficiency of the solar power generation system; [0003] Most of the traditional solar photovoltaic modules adopt fixed installation, that is, the battery panels are fixed on the support structure and do not move with the change of the sun's position. This result will seriously affect the conversion efficiency; deviation, the output power of the photovoltaic module array will drop by about 10% due to the reduction of the vertically ...

Problems solved by technology

[0005] At present, there are two kinds of solar photovoltaic automatic tracking systems widely used, namely, horizontal single-axis tracking and inclined latitude angle single-axis tracking, while horizontal single-axis tracking and tilting single-axis tracking have only one degree of freedom of rotation; single-axis rotation and support realize vertical Tracking in the pitch direction and the horizontal direction will concentrate the load on the driving shaft, resulting in excessive downward deflection, unbalanced rotational torque, and low tracking accuracy, which will increase the power consumption of the motor and reduce the service life of the machine and motor
