Summary of the invention
Because present stage photovoltaic plant swinging mounting demand and the shortcoming of current swinging mounting, the utility model devises a kind of photovoltaic module support with angle of incidence of sunlight automatic rotation.It is made up of angle of incidence of sunlight collecting part, signal of telecommunication drive part and electromagnetic induction rotating part, can realize the automatic rotation adjustment according to different angle of incidence of sunlight, make assembly be in the function of optimized incidence all the time.
Native system, can realize that different longitude and latitude followed automatically by support, different time angle of incidence of sunlight carries out two dimensions and rotates, and allows assembly receive maximum permissible exposure, produces maximum electric energy.
This hardware comprises with lower part:
The angle of incidence of sunlight collecting part be made up of many baby battery sheets, signal of telecommunication drive part and the electromagnetic induction rotating part with recovery spring.Wherein signal of telecommunication drive part and electromagnetic induction rotating part respectively have again two same sections, and the thing that this two covers part realizes support respectively rotates and rotates up and down.
Angle of incidence of sunlight collecting part is the hemispherical objects adopting many baby battery sheets of material identical with assembly to cover.Solar irradiation is mapped on different baby battery sheets, and each baby battery sheet is different from angle of incidence of sunlight, then accepted irradiance is different, and therefore, each baby battery sector-meeting produces different electric currents, and current signal changes into voltage signal.These voltage signals and sunlight irradiation degree are one to one, and therefore, these voltage signals just can reflect angle of incidence of sunlight exactly.
Signal of telecommunication drive part is input in full-control type gate circuit transistor gate by voltage signal corresponding for the angle of incidence of sunlight of solar light collection part collection, because of full-control type gate circuit transistor gate load small voltage can trigger full-control type turn on thyristors, reach sunlight voltage difference faint between each baby battery sheet also can driving arm rotate condition.After full-control type turn on thyristors, direct current is through full-control type turn on thyristors.Like this, the weak voltage difference that solar light collection part produces is converted to the electric current required for holder pivots.
Electromagnetic induction rotating part is the coil electric current that signal of telecommunication drive part produces being flowed through band spring, because this coil is in the magnetic field of permanent magnet generation, according to left hand rule, Ampere force can be produced after being in the coil electricity stream in magnetic field, this power can make coil rotate, such coil drives holder pivots, allows assembly rotate to sunlight optimized incidence orientation.When the recovery spring of end winding ensures do not have irradiance, component recovery is to originally facing southeastern direction.
In the utility model:
Angle of incidence of sunlight collecting part converts sunlight to the faint signal of telecommunication through the baby battery sheet of diverse location;
The signal of telecommunication of angle of incidence of sunlight collecting part is converted to the big current driving east-west direction, above-below direction to rotate by two signal of telecommunication drive parts respectively;
The Ampere force effect that the electromagnetic induction rotating part that east-west direction and above-below direction rotate produces by the electric current of signal of telecommunication drive part rotates;
Assembly support with the automatic turn of angle of incidence of sunlight follows different regions, and the incidence angle of different time sunlight is rotated and rotated, and makes assembly remain the orientation of optimized incidence.Do not have the night of sunlight, support can return to direction, east by south under the effect recovering spring.The utility model follows angle of incidence of sunlight in real time rotate and rotate, and do not need because of different regions, time adjustment application program.
The support of this automatic rotation does not need manual adjustments or update routine, accurately reliably.And electromagnetic induction driving arm rotates, stability is strong.On hardware the part such as angle of incidence of sunlight collecting part, coil, full-control type thyristor economical and practical, easily realize.

Embodiment
Further illustrate making with the photovoltaic module support specific structural features of the automatic turn of angle of incidence of sunlight and implementation and the effect that reaches below in conjunction with Fig. 1 ~ 5.Can find out that this support comprises angle of incidence of sunlight collecting part, Rotatable bracket two parts composition from Fig. 1 of native system.Angle of incidence of sunlight collecting part, gathers angle of incidence of sunlight and can realize the rotary motion of support with angle of incidence of sunlight by the two parts embedding internal stent, make assembly be in the orientation of optimized incidence all the time.
Fig. 2 is the schematic diagram of angle of incidence of sunlight collecting part, can find out in figure that angle of incidence of sunlight is made up of many baby battery sheets identical with assembly material, these baby battery sheets can accept the sunlight in each orientation in a day, the incidence angle accepting sunlight due to these baby battery sheets is different, and suffered irradiance is not identical yet.Because the electric current impact of irradiance on cell piece is comparatively large, therefore the electric current of each baby battery sheet generation is not identical yet.

2time, gate pole G turns off, and does not have electric current to flow through in thyristor.
Electric current I flows through the coil with spring in the diagram, and this coil is in fixed magnetic field, is known by Ampere's law, and this electric current produces Ampere force on coil.Support rotates under the driving of Ampere force.
When rack-mount angle of incidence of sunlight collecting part is just to solar time (assembly reaches optimum angle of incidence), each cell piece difference between current of angle of incidence of sunlight collecting part is zero, and full-control type thyristor gate pole tension is zero.Full-control type thyristor turns off, and Ampere force disappears, and support stops the rotation, and assembly keeps optimized incidence.Until after next angle of incidence of sunlight rotates to and can drive solar light collection part generation current, carry out the rotation of next support.
Fig. 5 shows: the original driving factors that this runing rest adopts sunlight to rotate as support, use the power that the direct current flowing through permanent magnetic field rotates as support, avoid the fixed mode that driven by program rotates, photovoltaic module support is flexibly and accurately rotated with angle of incidence of sunlight.
