Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing:

[0025] like figure 1 Shown is a schematic diagram of the overall structure of the system, which includes a tracking board 1, a photosensitive telescopic module (2(1), 2(2), 2(3), ..., 2(n-2), 2(n- 1), 2(n)) and support module 3. The photosensitive telescopic modules are evenly arranged along the circumference 4 of the track plate edge. The internal structure of each module is the same, such as image 3 Shown is a schematic diagram of its internal structure, including a photosensitive unit 21 , a trackpad connection unit 22 , an elastic support unit 23 and a telescopic unit 24 .

[0026] When sunlight obliquely enters the system, the photosensitive unit 21 of each photosensitive telescopic module converts the light difference signal inside and outside the circumference 4 at its position into an electrical signal and outputs it to the telescopic unit 24, and the telescopic...

Abstract

The invention discloses a bionic daylight tracking system based on eutropic principle of sunflower, comprising a tracking board 1, photosensitive stretching modules (2(1), 2(2), 2(3),... 2(n-2), 2(n-1), 2 (2) (n=2, 3, 4...)) and a supporting module 3. The internal parts of the photosensitive stretching modules are the same; and the photosensitive stretching modules are evenly arranged into a circle along the circumference 4 of the tracking board edge and positioned in parallel. Each photosensitive stretching module correspondingly stretch out or draw back according to the difference of light intensities at inner and outer sides of the circumference 4 at the positions where the photosensitive stretching modules are arranged so as to complete the sun-facing function.

Description

technical field [0001] The invention relates to the field of automatic sunlight tracking systems, in particular to a sunflower-style artificial sunlight tracking system. Background technique [0002] As a kind of abundant green energy, solar energy has a very broad application prospect, so it has received more and more attention, and an automatic daylight tracking system that can effectively improve its utilization rate has also emerged as the times require. The existing daylight tracking systems in China include solar motion trajectory tracking and photoelectric tracking in terms of tracking control methods, and one-way tracking and two-way tracking in terms of tracking realization structure. and azimuth (ie, east-west and north-south directions) are tracked simultaneously. For example, "a sun orientation detection device for automatic sun tracking" published by application number 200920196802.9, that is, a sun orientation detection device based on photoelectric control co...
