Fixed-point reflective sun tracking system

Abstract

The invention relates to a fixed-point reflective sun tracking system, and belongs to the technical field of environmental protection and energy conservation. The fixed-point reflective sun tracking system comprises a plane mirror matrix composed of a plurality of plane mirrors, and the back of each plane mirror is provided with a heating film capable of heating the corresponding plane mirror independently. The plane mirror matrix is connected with a driving device, and the driving device is connected with a controller. The controller enables all the plane mirrors in the plane mirror matrix to move horizontally in the same plane through the driving device so as to enable the plane mirror matrix to form any plane figure according to the area required to receive irradiation of sunlight. The fixed-point reflective sun tracking system further comprises a sensor enabling the fixed-point reflective sun tracking system to follow the sun. The system enables a place which cannot receive sunlight for a long time to be irradiated by sufficient sunlight on fine days. The fixed-point reflective sun tracking system has the advantages of being high in sunlight reflectivity, low in carbon, environmentally friendly, convenient to maintain and use and suitable for being used in ordinary families, and integrates environmental protection, safety and health.

Description

technical field [0001] The invention relates to a fixed-point reflective sunlight tracking system, which belongs to the technical field of environmental protection and energy saving. Background technique [0002] At present, in the field of solar energy utilization, since the incident direction (azimuth angle and altitude angle) of the sun's rays is constantly changing relative to a certain point on the earth, in order to collect solar radiation energy with maximum efficiency in different seasons and at different times, gather The light device must use an automatic tracking device to track the sun at any time. Generally, the higher the concentration ratio, the higher the requirements for tracking accuracy and the higher the cost. Therefore, from the comprehensive consideration of energy utilization and economy, low-cost solar ray tracing technology is of great significance. [0003] In terms of solar tracking, my country developed a single-axis solar tracker in 1997, which...
