Abstract
The invention discloses a method for tracking the sunlight irradiation direction. Four photoresistors are arranged on a spherical structural part capable of rotating in two vertical directions, and connected to form an electrical bridge. A power source is applied to each two opposite endpoints of the electrical bridge, and tracking of the sunlight irradiation direction can be adjusted according to whether the electrical bridge is balanced or not.
Description
Technical field
The present invention relates to a kind of device of following the tracks of the solar light irradiation direction.
Background technology
In the application of solar-energy photo-voltaic cell, the direction of cell panel need to be faced always the direction of illumination of sunshine, could allow like this work of cell panel be in most effective state, since in throughout the year every day sunshine direction of illumination all changing, so need to follow the trail of sun direction of light.
Summary of the invention
Purpose of the present invention just provides a kind ofly can accurately follow the tracks of the device of solar light irradiation direction.
Purpose of the present invention realizes by following technical solution: on the structure of a sphere of having determined the two poles of the earth, choose a latitude circle, symmetrical on this latitude circle 4 identical photoresistance are set, under solar light irradiation, only when the line at the two poles of the earth is consistent with the sunshine direction, the resistance of the photoresistance on the spheroid could be consistent, quadrangle is done in 4 photoresistance connected into electric bridge, connect into other spherical structure body and be provided with two vertical rotating shafts, the line that is parallel to respectively adjacent two photoresistance, spheroid inside is provided with rotary drive mechanism, can rotate freely around two rotating shafts respectively, when the line at the two poles of the earth and sunshine direction were inconsistent, the orientation angle of spheroid was adjusted in rotation, until the resistance of photoresistance is consistent.
Because the present invention is provided with 4 photoresistance at spherical structure body Same Latitude circle, reflect its diverse location under sunray with photoresistance in the resistance under the sunshine, can make things convenient for the direction relations of determining accurately between spheroid the two poles of the earth line and the sunray, with the light-struck direction of this sun-tracing.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention, and accompanying drawing 2 is electrical schematic diagrams of the present invention.
Embodiment
In the accompanying drawing 1, the 1st, there is the spheroid of rotary drive mechanism inside, L1 and L2 are respectively the mutually perpendicular turning axles of the both direction of spheroid, 2,3,4,5 is respectively 4 photoresistance that are arranged symmetrically with on the Same Latitude circle on the spheroid, line 11 is parallel with L2 with turning axle L1 respectively with 12 in twos for it, photoresistance 2,3,4,5 (is respectively R1, R2, R3, R4) as shown in Figure 2 mode connects and is four jiaos bridge circuit, when spheroid the two poles of the earth line is parallel with the direction between the sunray, 4 plane and sunray perpendicular directions that photoresistance is determined, resistance is consistent, Fig. 2 electric bridge complete equipilibrium, when the direction between spheroid the two poles of the earth line and the sunray is not parallel, 4 plane and sunray direction out of plumb that photoresistance is determined, resistance is inconsistent, Fig. 2 electric bridge is uneven, first electric bridge 1 and 3 between apply power supply, measure the potential difference (PD) between 2 and 4, rotate simultaneously L1, until the potential difference (PD) between 2 and 4 is zero, then electric bridge 2 and 4 between apply power supply, measure the potential difference (PD) between 1 and 3, rotate simultaneously L2, until the potential difference (PD) between 1 and 3 is zero, the electric bridge complete equipilibrium.
Claims (1)
1. the device of a sun-tracing irradiation direction, feature has been determined the two poles of the earth at one, can be provided with at the spherical structure body of two mutually perpendicular direction rotations 4 identical photoresistance, these 4 photoresistance connect into electric bridge, between two pairs of end points of electric bridge, apply power supply respectively, adjust the angle of spheroid, until bridge balance.
