Embodiment
The unilateral positioningly day tracing system of a kind of photovoltaic as depicted in figs. 1 and 2, including photovoltaic module 1, tappet
2, pedestal, universal wheel 4 and part reflective semitransparent film reflecting plate 6, one end of the photovoltaic module 1 are supported by tappet 2, the tappet
2 top is flexibly connected by universal wheel 4 and guide rail 5 with the photovoltaic module 1, and the bottom of the tappet 2 is additionally provided with first
Pedestal 3；The other end of the photovoltaic module 1 is supported by the second pedestal 9, between second pedestal 9 and the photovoltaic module 1
Universal wheel 4 is additionally provided with, part reflective semitransparent film reflecting plate 6 is additionally provided with immediately below the photovoltaic module 1；The system also includes Comprehensive Control
Device, the input of the integrated controller are connected to wind sensor 7 and light intensity sensor 8, the integrated controller
Output end is also associated with branch frame transmission mechanism.
The unilateral positioningly day tracing system of a kind of photovoltaic of the present invention is mainly concerned with three technology points：It is single
Side detent mechanism, reflecting plate integrated technology and high wind protection.
(1) unilateral detent mechanism
Unilateral detent mechanism has two parts composition：Mechanical driving device and electronic circuit control
Track of sun tracking is divided into Bearings tracking and pitching angle tracking.Two kinds of angles of biaxial system can all follow the trail of, single shafting
It is more as unified to track azimuth.In this application, our positioning is the tracking of the angle of pitch.This tracking has the following advantages：
1. without all significantly adjustment angle daily.
2. transmission mechanism service life is longer than azimuth tracker.
3. high wind weather can be tackled, ensure the practical security of integral product, especially in the more typhoons of southern china
Area.
Data based on simulated experiment, we obtain the light intensity gain of this patent product, as shown in the table：
In this table, the system with pitching angle tracking can obtain 1370kwh/m2Intensity of illumination, than other fixed angles
Degree can be higher by minimum 4%.Because this simulation is based only on two periods, two kinds of angles, so this is minimum data, it is real
The gain on border can meet our pursuits to gain standard 10% or so.
The tracking principle of the application is as follows：
1. two tappets support photovoltaic module side with 45 ° of directions, opposite side is fixed with Universal wheel structure.
2. photovoltaic module elevation angle scope can be by 0 ° to 45 °.
3. tappet stroke is determined by integrated controller.
Controller controls tappet stroke by annual big data and light intensity sensor signal, ensures annual in most
The good angle of pitch.
(2) reflecting plate integrated technology
In order to increase the generated energy of backboard gain component, we install the reflection of high reflectance in tracking system base bottom
Plate.The technical requirements of reflecting plate are as follows:
1. reflecting the spectrum of photovoltaic cell response wave band to greatest extent, i.e., wave band is 300nm to 1100nm spectrum.
2. the light of the other wave bands of projection, to meet application product daylighting demand.
Reflectivity is determined by below equation：
Eo=ER+EA+ET
E0 expressions impinge upon total quantity of illumination of reflecting plate, and ER represents volume reflection, and EA represents to represent projection amount by uptake, ET.
So on material is selected and processed, reduction Ea, the Et for response spectrum wave band of demaning reduction of big degree to the greatest extent, this
Sample can increase Er.
Therefore, the technology composition of reflecting plate is high printing opacity object, the substrate of the application is lucite, and spectrum is
300nm to 1100nm part reflective semitransparent film coating.
(3) high wind is protected
High wind protection is the characteristic of the application.Commonly sun-tracker has ground support, structure due to bulky
It is designed to if, can resist must live general high wind.However, the characteristic of this patent is to be applied to small sized product, quality and body
Product is all the smaller the better, including the photovoltaic module of support is all lighter 20%-30% than in general.So this patent product can not
Carry out anti-high wind by weight and stable ground, especially coastal more typhoon regions.In order to protect the application product being related to
And the safe handling of photovoltaic module, in this patent, we look for another way, and take the mode of " drainage, dredge " to evade high wind
Infringement, particular technique realize it is as follows：
1. wind sensor is as support (pedestal) side or surrounding, at any time test site wind-force.
2. the integrated controller connection of the tracker of wind sensor and support, is sent to wind-force signal.When test wind
When power reaches the wind resistance grade of involved application product, controller sends signal to transmission tappet, and tappet shrinks so that the angle of pitch
It is changed into zero degree, whole photovoltaic module recovery is parallel with product plane among application product.So, component and transmission mechanism
The shell protection of whole application product is received, high wind to it also from photovoltaic module surface by that will not produce physical injury.
When the angle of pitch is changed into zero degree, photovoltaic module or normal work.Because typhoon weather is occurred in summer, summer
Optimum pitch angle be 10 degree or so.So being changed into zero degree even in the high wind weather angle of pitch, one still can be kept very well
Photoelectric transformation efficiency.
This patent the actual effect of contrast different type tracking, employs unilateral tracking according to photovoltaic system simulation model
Concept, introduce reflecting plate and high wind safeguard measure so that the tracking system of this patent is the same as " efficient light backplane gain photovoltaic
Component " is combined, and produces the effect got twice the result with half the effort, and can greatly improve system generating efficiency, and can be with middle-size and small-size application
Product is combined, and promotes the development of photovoltaic products miniaturization.
The above described is only a preferred embodiment of the present invention, any formal limitation not is made to the present invention, though
So the present invention is disclosed above with preferred embodiment, but is not limited to the present invention, any to be familiar with this professional technology people
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
For the equivalent embodiment of equivalent variations, as long as being the content without departing from technical solution of the present invention, the technical spirit according to the present invention
Any simple modification, equivalent change and modification made to above example, in the range of still falling within technical solution of the present invention.
