Embodiment Construction

[0012] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

[0013] Such as figure 1 , controller (1) and hydraulic station (2), hydraulic cylinder (3), heat collector (4), light sensor (5) and logic control algorithm constitute a closed-loop control system; controller (1) and hydraulic station (2 ), the hydraulic cylinder (3), the heat collecting tank (4), the angle sensor (6), the sun position time control algorithm and the corresponding logic control algorithm constitute a closed-loop control system.

[0014] Install the light sensor so that the lens barrel of the light sensor (5) is parallel to the normal line of the opening of the solar heat collecting tank, and measure the azimuth and the local longitude and latitude of the solar heat collecting tank, so that the solar position time control algorithm can calculate the solar heat collecting tank the tracking angle. An angle sensor (6) is installed to p...

Abstract

The invention discloses a light-controlled solar energy heat collecting groove sun chasing system which is characterized in that a light sensor, an angle sensor, a position sensor, a pressure sensor and a sun position time control algorithm are used for guaranteeing the accuracy, stability, reliability and safety of the sun chasing. The light sensor provides the accurate sun position information, the angle sensor and the position sensor provide the position information of a heat collecting groove, the pressure sensor provides the real-time pressure information of a hydraulic station, and the sun position time control algorithm calculates the theoretical sun position information to guarantee that a normal sun chasing function is restored when an extreme condition happens.

Description

technical field [0001] The invention relates to the field of solar energy utilization, in particular to a solar heat collecting trough day-by-day system which forms a closed-loop control circuit day by day through an optical sensor and a sun position time control algorithm. Background technique [0002] The effective use of solar energy will not only alleviate my country's energy problems and reduce the emission of harmful gases such as carbon dioxide, but also have great and far-reaching significance for protecting the ecological environment and ensuring the continuous and stable supply of energy in the process of economic development. [0003] Solar thermal application has a long history, but the low energy flux density and intermittent radiation of solar energy limit the application of solar thermal. Solar thermal collectors have attracted wide attention due to their high heat collection temperature and long solar energy utilization time. Based on the high-accuracy and hi...
