Specific embodiment
Present invention will be described in further detail below with reference to the accompanying drawings, to enable those skilled in the art referring to specification text
Word can be implemented accordingly.
As shown in Figure 1, the present invention provides a kind of solar panel ray height angle automatic following systems, for adjusting
The elevation angle of solar panel, makes it receive sunlight to greatest extent.Solar panel ray height angle is automatic
System for tracking includes pedestal 110, solar panel 120, telescopic device 130, ray height angle detecting device 140 and drives
Dynamic circuit.
For pedestal 110 in being horizontally disposed with, the solar panel 120 is mounted on the top of pedestal 110, and solar-electricity
It is hinged on pedestal 110 at 120 bottom center of pond plate, so that solar panel 120 is rotated around hinge joint, to change
The elevation angle of solar panel 120.
One end of telescopic device 130 is hinged at the top center of solar panel 120, and the other end is hinged on pedestal
110 one fixed points of inside.The telescopic device 130 can change length so that the solar panel 120 is cut with scissors around bottom end
Contact rotation is to change the elevation angle of solar panel 120.
Ray height angle detecting device 140 is set at 110 upper surface of pedestal, for detecting the height of sunray
Angle.
As shown in Fig. 2, the ray height angle detecting device 140 includes shadow bar 141 and the first to the n-th total n light
Sensor 142.Wherein, shadow bar 141 is rod-shaped in elongate cylinder, is perpendicularly fixed on 110 upper surface of rotating base.Institute
It states the first to the n-th light sensor to be linearly arranged successively, and straight line passes through shadow bar where the first to the n-th light sensor
The 141 bottom surfaces center of circle, and the projection with the normal of solar panel 120 in 110 upper surface of pedestal is parallel.
A set of radiation direction system for tracking is provided on device of solar generating, with ray height provided by the invention
Angle automatic following system is used in combination.Radiation direction system for tracking is used first, is adjusted the deflection of pedestal 110, is made the sun
The deflection of energy solar panel 120 is equal with the deflection of light.At this point, light is radiated at the shade energy generated in shadow bar 141
Cover one or more of the first to the n-th light sensor.When shade covers on the first to the n-th light sensor,
The first to the n-th light sensor being capable of output signal.Therefore, according to the quantity of capped light sensor 142, energy
Enough preresearch estimates go out the length of shade, and the elevation angle of light can be calculated in the case where known projection 141 height of bar.
The signal control telescopic device that the driving circuit is exported by the first to the n-th light sensor stretches out specific long
Degree, drive the solar panel around bottom end hinge joint rotate, make the angle of solar panel normal and horizontal plane with too
Sunlight line is equal with the angle of horizontal plane, and sunlight vertical irradiation makes solar panel on solar panel 120 at this time
120 can receive sunlight to greatest extent.
In another embodiment, the ray height angle detecting device 140 is provided with two sets, is located at the solar energy
The front and rear sides of solar panel 120, to prevent the shade of solar panel 120 from covering the ray height angle detecting device
140。
In another embodiment, the telescopic device 130 includes concatenated the first to the n-th cylinder.The first to the n-th light
Line sensor 142 is light-operated switch.Wherein each light-operated switch controls one two five ventilation moving electromagnetic valves, that is, controls a gas
Cylinder.When a light sensor 142 is blocked by shadow, a cylinder stretches out.
In another embodiment, the telescopic device 130 is in when fully collapsed condition at the solar panel 120
In horizontal position.When sunlight vertical irradiation is on the ground, shadow bar 141 will not generate shade, at this time the first to the n-th light
Sensor is not blocked, and the first to the n-th cylinder is in contraction state, and solar panel 120 keeps horizontal position at this time
It sets, just makes sunlight vertical irradiation on solar panel 120.
As one preferred as shown in Fig. 3 Fig. 4, the stroke of the first to the n-th cylinder is equal, the first light level
Distance of the device to the n-th light sensor apart from shadow bar 141 is successively from closely to remote.When solar irradiation is mapped in shadow bar 141, produce
When raw projection is covered on i-th of light sensor, the angle α of sunray and horizontal plane is at this time
Wherein, h is the height of shadow bar, siDistance for i-th of light sensor away from shadow bar.
Meanwhile thering is i cylinder to stretch out, telescopic device 130, which props solar panel 120, at this time makes solar panel
120 meet with the angle β of horizontal plane
Wherein, L1It is telescopic device bottom end at a distance from solar panel bottom end, L2It is up and down the two of solar panel
The distance at end, L3For telescopic device initial length, d is the stroke of a cylinder, and θ is telescopic device bottom end and solar panel
The angle of bottom end line and horizontal plane.
When vertical with solar panel with sunlight, solar panel, which can absorb to greatest extent sunlight, is,
It needs to meet at this time
Solve si
Therefore, when the components needed for selection system, the identical cylinder of model may be selected, make the stroke of each cylinder
It is d, and when arranging the first to the n-th light sensor, it is only necessary to the s of above-mentioned calculating is installediValue, to arrange, can make too
Positive energy solar panel is in the position for receiving sunray to greatest extent always, provides the power generation of device of solar generating significantly
Amount.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
In specific details and legend shown and described herein.
