Embodiment Construction
[0019] The present invention will be further described below in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0020] When sunlight illuminates the system obliquely, there is always a photosensitive block in the photoelectric disk that is closest to the sun, while the other photosensitive block that is symmetrical to it is the farthest from the sun. The photosensitive block closest to the sun is blocked by the reflective strip, while the photosensitive block farthest from the sun is not only unblocked but also irradiated by the reflected light of the reflective strip, so that the voltage difference between the two is obvious. At this time, the system output voltage The signal makes the telescopic tube closest to the sun shorten, and the telescopic tube farthest from the s...

The invention relates to a sunflower sun-exposing principle-based automatic light tracking system. The system comprises a light tracking plate, a supporting column, a bearing, contractible tubes and a base. The system is characterized in that the light tracking plate is provided with a circular photoelectric disk; a photovoltaic power generation sheet is laid at the bottom of the circular photoelectric disk; the edge of the photovoltaic power generation sheet is evenly divided into 2n photosensitive blocks which are equidistantly spaced from the center of the bottom of the circular photoelectric disk; a circle of light reflection bar is erected around the circular photoelectric disk; the supporting column is erected on the base and supports the light tracking plate at the center of gravity through the bearing; the contractible tubes are parallel to the supporting column and are equidistantly spaced from the axis of the supporting column; a plurality of electromagnetic capsules are connected end to end as to form the contractible tube; the number of the contractible tubes is the same as that of the photosensitive blocks; the contractible tubes are in one-to-one butt joint with photosensitive blocks at corresponding positions through related circuits; and the contractible tubes can stretch and contract differently according to the illumination intensity of the photosensitive blocks, so that the light tracking plate can rotate by certain angles. According to the sunflower sun-exposing principle-based automatic light tracking system of the invention, solar energy and photoelectric signals are directly utilized; electromagnetic force driving is utilized directly to realize stretch and contraction amount, and the sunflower sun-exposing principle-based automatic light tracking system can be conveniently applied to different fields such as large-scale photovoltaic power generation and automatic drying systems.
Description
technical field [0001] The invention relates to the field of automatic tracking of sunlight, in particular to an automatic light tracking system based on the principle of sunflower facing the sun. Background technique [0002] At present, most of the existing daylight tracking systems in China use solar trajectory tracking control or photoelectric tracking control. Their common feature is to use the control program to track after feeding back the control signal. The complexity of the system is high, which limits its application range. Application No. 201110136322.5 published "A Sunflower Sun-brightening Principle Based on Sunflower Sun Tracking System", which provides an automatic sun tracking system based on the sunflower sun-bionic bionic principle, through the photoelectric tracking control of photosensitive elements and related circuits, it gets rid of the complicated Logic circuit structure and control program. Although the complexity of this system has been reduced, t...
