Fixed-point reflective sunlight-tracking system

Abstract

The invention relates to a fixed-point reflective sunlight-tracking system and belongs to the technical field of environment protection and energy saving. A plurality of plane mirrors are laid on a support frame of the plane mirrors. A heating film is arranged at the back part of each plane mirror so that each mirror can be heated independently. The small plane mirrors are combined to form a matrix. A mechanical device, which is driven by a motor and connected with a one-chip-microcomputer controller, is arranged on each plane mirror. The small plane mirrors in each line and each row of the matrix can be adjusted upwards and downwards and left wards and rightwards independently. Positioning sensors are installed in places in which projection is needed. The device enables a place in which sunlight is unavailable for a long time to obtain sufficient sunlight irradiation in sunny days and has the characteristics of being high in reflectivity, low-carbon and environment-friendly and convenient to maintain and use. The device is applicable to occasions such as family houses, factories, office buildings and agricultural sheds and the like so that the device is an energy-saving and safe and health product.

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...
