Shadow shield physical dimension in shadow shield group 2 is identical, and the distance between adjacent two shadow shields in shadow shield group 2 is identical, and each shadow shield is parallel to each other, transparent or unobstructed between shadow shield.
Photoelectric sensor 3 is identical with photoelectric sensor 5 physical dimension and photoelectric parameter, photoelectric sensor 3 and photoelectric sensor 5 are arranged at the both sides near shadow shield group 2, photoelectric sensor 3 is identical with the distance of shadow shield group 2 with photoelectric sensor 5, and after tabula rasa group, photoelectric sensor 3 is identical with the distance of base plate 1 with photoelectric sensor 5.
Photoelectric sensor 4 is arranged between shadow shield group outermost two shadow shields.
Principle of work of the present utility model is as follows.
The rectilinear propagation principle of light, the spacing of the adjacent shadow shield of shadow shield group is very little can block the light with shadow shield vergence direction, make to be blocked the bottom of light irradiation less than shadow shield group, light and light when vertical two planes are all parallel are mutually perpendicular to the bottom surface all vertical with two planes.
Arrange a set of solar tracking locating device to follow the trail of sun horizontal direction, shadow shield group is parallel to horizontal direction and follows the trail of axis, when light with the angular illumination being not parallel to shadow shield to this solar tracking locating device time, shadow shield group all can cover some light, it is different that photoelectric sensor 3 and photoelectric sensor 5 accept solar irradiation area, produce different curtages, thus can judge that the sun is positioned at shadow shield group generation current or the large photoelectric sensor side of voltage, control device can control actuating unit according to this signal and rotate to respective direction, along with device rotates, light moves closer to and is parallel to shadow shield, the difference of photoelectric sensor 3 and photoelectric sensor 5 generation current or voltage reduces gradually, now photoelectric sensor 4 is still blocked plate group completely and covers, when the angle of light and shadow shield is less than device maximum error angle (according to the distance of adjacent two shadow shields of shadow shield group and photoelectric sensor 4 ratio to the distance at shadow shield edge, tangent of negating can calculate solar ray energy and shine the maximum error angle of photoelectric sensor 4 and the maximum error angle of device) time, the curtage of photoelectric sensor 4 can become suddenly large, control device controls actuating unit and stops operating, now can think that light is parallel with shadow shield, namely this position is exactly position location in the horizontal direction.
Separately arrange a set of solar tracking locating device to follow the trail of sun pitch orientation, shadow shield group is parallel to pitch orientation and follows the trail of axis, when light with the angular illumination being not parallel to shadow shield to this solar tracking locating device time, shadow shield group all can cover some light, it is different that photoelectric sensor 3 and photoelectric sensor 5 accept solar irradiation area, produce different curtages, thus can judge that the sun is positioned at shadow shield group generation current or the large photoelectric sensor side of voltage, control device can control actuating unit according to this signal and rotate to respective direction, along with device rotates, light moves closer to and is parallel to shadow shield, the difference of photoelectric sensor 3 and photoelectric sensor 5 generation current or voltage reduces gradually, now photoelectric sensor 4 is still covered completely, when the angle of light and shadow shield is less than device maximum error angle (according to the distance of adjacent two shadow shields of shadow shield group and photoelectric sensor 4 ratio to the distance at shadow shield edge, tangent of negating can calculate solar ray energy and shine the maximum error angle of photoelectric sensor 4 and the maximum error angle of device) time, the curtage of photoelectric sensor 4 can become suddenly large, control device controls actuating unit and stops operating, now can think that light is parallel with shadow shield, namely this position is exactly the position location in pitch orientation.
When completing tracing and positioning to the sun of horizontal direction and pitch orientation, light direct projection helioplant, completes the accurate tracing and positioning to the sun.
This device does not affect by light intensity, when the cloudy day or when YIDUOYUN coloured silk covers sunlight suddenly, light dies down, but still can judge the sun is positioned at which side with shadow shield group by the voltage that compares photoelectric sensor 3 and photoelectric sensor 5 or current values, draw the direction of following the trail of the sun, when photoelectric sensor 4 is covered completely, curtage is very little, and when light is parallel with shadow shield, photoelectric sensor 4 curtage also can suddenly change and reach the object of accurate tracing and positioning position of sun.
Light is dark in when being not suitable for helioplant work, namely when in the voltage of photoelectric sensor 3 and photoelectric sensor 5 or current values, a larger numerical value is less than a certain limit value, control device controls helioplant and stops operating, reduce and rotate power consumption, need not reset, directly restart when waiting light intensity to recover to follow the trail of.
Do not affect by solar motion track, the solar tracking locating device of horizontal direction and pitch orientation can accept control device simultaneously and drive actuating unit to rotate, and completes level and pitching both direction is located simultaneously.
