All-day automatic tracking system

Abstract

The invention relates to an all-day automatic tracking system. The system comprises a photovoltaic assembly, an installation platform, hydraulic cylinders, hydraulic cylinder installation seats and a hydraulic control power unit which adjusts the strokes of the hydraulic cylinders; the hydraulic cylinder installation seats are all arranged on the installation platform; the hydraulic cylinders arearranged on the installation platform; each hydraulic cylinder comprises a cylinder body and a piston rod; the cylinder bodies are connected with the hydraulic cylinder installation seats through trunnions; the end of the piston rod of each hydraulic cylinder is connected with the fixed end of the lower surface of the photovoltaic assembly through a universal joint; the all-day automatic trackingsystem also comprises an electric centralized control system for controlling the hydraulic control power unit to act, a follow light sensor used for measuring the required offset adjusting value of the photovoltaic assembly and an inclined sensor used for measuring the position offset adjustment value of the photovoltaic assembly; the horizontal reference surface of the inclined sensor is parallel to the surface of the photovoltaic assembly; and the orientation shaft Z of the follow light sensor is vertical to the surface of the photovoltaic assembly. The all-day tracking system can be used for atrocious weather, can realize accurate automatic tracking and consumes less electricity.

Description

technical field [0001] The invention relates to an all-sky tracking system, especially a three-point hydraulic support that can adjust and control the azimuth and elevation angles in a large angle range and is widely used in large-diameter tracking radars, radio telescopes, All-sky tracking system for satellite antenna, solar receiving system and other equipment. Background technique [0002] The all-sky tracking system is widely used in tracking radar, radio telescope, satellite antenna, solar receiving system and other equipment. Taking the solar receiving system as an example, the control mode of most tracking systems is mechanical transmission, and the control form is single-axis control. The utilization rate is the highest when the sun’s incident light is perpendicular to the photosensitive surface, and the utilization rate becomes smaller as the deflection angle increases. Since the single-axis control can only realize the control of one azimuth, the trajectory of the...

Problems solved by technology

The current all-sky tracking system is mainly driven by two-axis motors for tracking and positioning. It controls the orientation of photovoltaic modules at the current time by measuring the current latitude and longitude. During the attitude control and maintenance process, power consumption will be consumed, which will affect the utilization efficiency of solar energy. Domain tracking systems generally work in the field for a long time, the environment is harsh, the working conditions are harsh, and the probability of failure is high
