The fixed-day tracking probe belongs to the field of solar energy utilization. The structure of the existing tracking probe is too complicated, the cost is too high, and it is not practical. A photosensitive element is installed on the base or/and the light column. Horizontal azimuth detection and sun height detection use light column projection: when the light column axis does not coincide with the sun's rays, the light column will produce projections on the photosensitive elements in the backlight direction, so that the photosensitive elements on the backlight surface and the photosensitive elements on the light-facing surface are electrically conductive. The characteristics change, and after the circuit is compared and amplified, it drives the horizontal azimuth tracking motor/and the altitude tracking motor, so that the photovoltaic square array rotates in the direction facing the light until the two opposite surfaces are facing the light. The utility model has the advantages of simple structure, complete functions and high cost performance.

Cloudy day is detected light activated element RG1 and is used for detecting the cloudy day, and the cloudy no solar time on the same day, the RG1 resistance increases, and this signal amplifies through circuit closed tracking circuit afterwards.
Detect light activated element RG2 night and be used to detect night, after darkness, detect light activated element RG2 resistance night and increase, after circuit amplifies, connect the level orientation drive motor and make the photovoltaic arrays front return the due east direction, so that entered duty in second day fast.
Meeting light detection light activated element RG5, RG6 is used to detect the photovoltaic arrays front and meets light or backlight.When the light time is met in the photovoltaic arrays front, meet light and detect the resistance of light activated element RG5 less than the resistance of meeting light detection light activated element RG6, these two signals are controlled the elevation angle tracking circuit after circuit relatively amplifies, make elevation angle and level orientation follow the tracks of to follow the tracks of simultaneously and adjust; If the photovoltaic arrays front is backlight, this signal will suspend elevation angle to be followed the tracks of, etc. level orientation follow the tracks of adjust to the right place after, restart elevation angle and follow the tracks of.
Tracking accuracy is mainly determined by the height H of light beam.Follow the tracks of angle of minimum resolution φ=arctg (D/H), D is that the distinguishable minimum light of light activated element is shone width, sees Fig. 3, and the diameter of light activated element is about 5mm, level orientation detects light activated element RG3 and RG4, elevation angle detect light activated element RG7 and the shared width of RG8 in order to reduce, and adopts the inclined-plane to install.
8 light activated element one ends all are connected together, and as public 0 line, the other end independently picks out respectively, have 9 output connection (see figure 4)s, and (see figure 1) is drawn in the hole in the middle of base bottom.
The settled date tracking probe of said structure is to be fixed together with photovoltaic arrays and can be the example explanation with the photovoltaic arrays changing location.
Said structure is a kind of twin shaft settled date tracking probe, and the settled date that is mainly used in a light gathering photovoltaic power generating system is followed the tracks of detection.
This probe both can have been made as this twin shaft settled date tracking structure of saying above (level orientation and elevation angle), also can make single shaft settled date tracking probe:
The firstth, sun level orientation uniaxiality tracking probe only needs to install level orientation at this moment and detects light activated element RG3, RG4, the cloudy light activated element RG1 of detection and detect light activated element RG2 night, and remaining light activated element has not just needed.The tracking that this probe can be used for dull and stereotyped tracking mode electricity generation system, flute profile or paraboloidal line light gathering photovoltaic power generating system detects.
The secondth, sun altitude uniaxiality tracking probe only needs the dress elevation angle to detect light activated element RG7, RG8 this moment and the cloudy day is detected light activated element RG1.The tracking and monitoring that can be used for the reflective line light gathering photovoltaic power generating system of all kinds of paraboloidals and flute profile.
When probe is installed, the light beam axis should from the direction of sunshine incident, be fixed on the holder in two-dimensional adjustable bearing left side according to the up north and down south left west and right east top of photovoltaic arrays perpendicular to the photovoltaic cell plane, and the adjustment bearing, make the axis of light beam vertical fully with the photovoltaic plane.The output line of probe is connected to tracking control unit.
