Abstract

The invention discloses a double-shaft solar automatic tracking power generation device and a sensing probe thereof. The sensing probe comprises a probe base, four photosensitive components and a cross-shaped partition board, and is characterized in that the cross-shaped partition board is arranged on the probe base and divides the probe base into four independent areas in light isolation, and the four photosensitive components are installed in the four independent areas of the probe base respectively. The sensing probe further comprises a light shielding piece and a dimming shell used for filtering away diffusion light, the light shielding piece is arranged on the top of the cross-shaped partition board, the four photosensitive components are located in an orthographic projection area, of the light shielding piece, on the probe base, namely when sunlight vertically irradiates the probe base, the four photosensitive components are located in the shade, formed on the probe base, of the light shielding piece, the dimming shell covers the cross-shaped partition board and the light shielding piece, a gap is reserved between the dimming shell and the light shielding piece, and the side end face of the cross-shaped partition board is tightly attached to the inner wall of the dimming shell. By means of the double-shaft solar automatic tracking power generation device and the sensing probe, automatic tracking of the position of the sun can be achieved.

Description

technical field [0001] The invention relates to a solar tracking power generation device and a sun position sensor thereof, in particular to a dual-axis solar automatic tracking power generation device and a sensing probe thereof. Background technique [0002] The so-called solar automatic tracking power generation device is to make the solar panel face the sun at any time, so that the sunlight can be irradiated vertically on the solar panel as much as possible in real time, so as to obtain the highest solar energy collection efficiency. The position of the sun in the sky is often described by the solar altitude angle and solar azimuth angle, such as figure 1 As shown, it is a schematic diagram of the sun's apparent daily movement trajectory of a certain place O. From the figure, it can be seen that the sunshine time of this place O is about 5 o'clock to 18 o'clock, and the sun appears at the position from T5 to T18 relative to the place O. Z is the direct upward direction ...

Problems solved by technology

[0007] First, the solar tracking sensor detects the position of the sun by comparing the light levels of each photoresistor. In order to create environments with different light levels, it uses a more complex channel structure, which increases the complexity of the production process. And it has high photosensitive requirements for photoresistors, and it is easy to reduce reliability due to interference in complex lighting environments;

[0008] Second, the above-mentioned solar tracking sensor is applied in different geographical locations in various regions, and it is necessary to design cylinders of different heights, and to change the width of the left, right, upper and lower channels, and its environmental applicability is poor;

[0009] Third, after the four photoresistors of the above-mentioned solar tracking sensor are exposed to light, a series of calculations are required to obtain the driving signals of the azimuth rotation axis and the elevation angle rotation axis of the rotating mechanism. The control algorithm of the power generation device controller is relatively complicated.
