Principle of work of the present utility model is as follows:
Object under the solar radiation can produce shade, and the direction of shade is consistent with the direction of sunray.
When the shade of level shadow device 3 does not cover horizon light electric transducer 2 fully, illustrate that base plate 1 does not reach sun direct projection in the horizontal direction, control device can rotate by control actuating unit motor in the horizontal direction after receiving the signal that horizon light electric transducer 2 transmits, shade up to level shadow device 3 covers horizon light electric transducer 2 fully, motor on the horizontal direction just stops operating, and makes base plate 1 reach sun direct projection in the horizontal direction.
When the shade of pitching dimmer 5 does not cover pitching photoelectric sensor 4 fully, illustrate that base plate 1 does not reach sun direct projection on pitch orientation, control device can rotate by the motor of control actuating unit on pitch orientation after receiving the signal that this moment, pitching photoelectric sensor 4 transmitted, shade up to pitching dimmer 5 covers pitching photoelectric sensor 4 fully, motor on the pitch orientation just stops operating, and makes base plate 1 reach sun direct projection in pitch orientation.
When the shade that covers horizon light electric transducer 2, pitching dimmer 5 fully when the shade of level shadow device 3 covered pitching photoelectric sensor 4 fully, base plate reached sun direct projection 1 this moment; When being used in the utility model on the photovoltaic module, because base plate 1 is installed in parallel on the photovoltaic module, so photovoltaic module reaches sun direct projection at this moment.
Sunray is dark during the cloudy day, but dimmer still exists obvious contrast between the shade that shines upon generation down and sunray, so this sniffer can continue accurately to locate position of sun, thereby make solar tracking device not be subjected to the influence of Changes in weather; When sunray secretly when being not suitable for helioplant work, the photoelectric sensor that detects intensity of illumination passes to control device with signal, control device can make solar tracking device quit work, the energy loss of reduction solar tracking device.
The movement locus of solar tracking coordinate detection device on the horizontal direction: from the morning to the evening, the sun's motion track is from the east orientation west, and the initial setting track of actuating unit also is that initial, set position is towards east from the east orientation west.Evening, actuating unit is towards the west, second day morning, actuating unit towards the west shake-up level sensor that can continue to turn an angle from the east orientation west, control device can make actuating unit reset in the horizontal direction after receiving the signal of level sensor, thus make actuating unit always sun-tracing rotate from the east orientation west.
The movement locus of solar tracking coordinate detection device on the pitch orientation: from the morning to the noon, the sun's motion track is Zi hanging down to high, and from the noon to the evening, the sun's motion track is to low Zi high.From the morning to the noon, actuating unit is followed the sun and is rotated to high Zi low; From the noon to the evening, actuating unit at first can continue to turn an angle to height Zi low.
Therefore, the utility model can be applied to any solar tracking device, focuses on photoelectric sensor and detects level, the pitch position that the shade that shines upon down dimmer is determined the sun.There is obviously contrast between shade and the sunray, can makes solar tracking device not be subjected to the influence of Changes in weather.
