Description
Technical field
The present invention relates to angle of sun rays fields of measurement, is applied particularly to the sun flash ranging in sun tracker
Position.
Background technology
For a long time, world energy sources relies primarily on the fossil fuel such as oil and coal, and these mineral are used as disposably not
Renewable resource, reserves are limited, and produce substantial amounts of carbon dioxide during burning, cause temperature of the earth to raise, and ecological environment is disliked
Change.Predicted according to International Energy Agency, the mankind are faced with the exhausted serious threat of fossil fuel.This global energy crisis,
Force national governments to put into substantial amounts of manpower and financial resources, research and develop new energy, such as solar energy.Solar energy is that one kind takes it
Clean energy resource not to the utmost, there is boundless application prospect using solar energy power generating.
Sun light tracking locator is the key device in solar photovoltaic generation system, currently used for observing solar activity
Or device it is expensive, it is complicated.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of simple in construction, and cheap is used for single shaft track of sun
The sunshine locator of tracks of device.
The technical solution adopted for the present invention to solve the technical problems is：A kind of sunshine locator, mainly including shading
Body, the first light-sensitive element, dust cover, base and the second light-sensitive element.
Wherein, the first light-sensitive element and the second light-sensitive element are obstructed by occulter, and occulter is a two sides angle
Into 5 ° of sphenoid；First light-sensitive element and the second light-sensitive element are fixed on base, and with base angle at 45 °, light-sensitive element
Lead drawn by base bottom, lead is connected with track of sun single shaft tracking apparatus again.Dust cover is by occulter, first photosensitive
Element, base, the second light-sensitive element cover in；Dust cover integral light-transmitting.
Preferably：Above-mentioned first light-sensitive element and the second light-sensitive element are all identical photo resistance of model and performance.
Preferably：Above-mentioned first light-sensitive element and the second light-sensitive element are model and performance all identical photosensitive tubes.
It is further：Above-mentioned base is shaped as circular or rectangle or rhombus.
The beneficial effects of the invention are as follows：
Sunshine locator of the present invention, overall structure is simple, is mainly made up of two pieces of light-sensitive elements and occulter, low cost
It is honest and clean, accurately track of sun uniaxiality tracking control can be realized.
Brief description of the drawings
Fig. 1 is the schematic front view of the present invention.
Fig. 2 is the schematic top plan view of the present invention.
Description of reference numerals:
1- occulters, the light-sensitive elements of 2- first, 3- dust covers, 4- bases, the light-sensitive elements of 5- second.
Embodiment
Below in conjunction with the accompanying drawings and embodiment describes the specific embodiment of the invention：
The structure that Fig. 1,2 show one embodiment of the invention, as illustrated, sunshine locator of the present invention utilizes light-sensitive element
Photosensitive property, when realizing to track of sun progress uniaxiality tracking, the whole device moment tracks the purpose of sunshine.
The present invention includes：Occulter 1, the first light-sensitive element 2, dust cover 3, base 4, the second light-sensitive element 5.Wherein,
One light-sensitive element 2 and the second light-sensitive element 5 are obstructed by occulter 1, to ensure that sunshine will not be radiated at the two light simultaneously
On quick element；Because photovoltaic generating system allows the error that has within 5 °, therefore occulter 1 is a two sides angle into 5 °
Sphenoid；First light-sensitive element 2 and the second light-sensitive element 5 are fixed on base 4, and with base angle at 45 °, light-sensitive element
Lead is drawn by the bottom of base 4, and lead is connected with track of sun single shaft tracking apparatus to control track of sun uniaxiality tracking again
The rotation of device；In the course of the work in order to avoid the pollutants such as dust, greasy dirt are to the corrosion contamination of the present invention, so as to have impact on
The precision of the present invention, is covered in occulter 1, the first light-sensitive element 2, base 4, the second light-sensitive element 5 with dust cover 3.It is dust-proof
Cover 3 is made by light transmissive material.
The above-mentioned light-sensitive element 5 of first light-sensitive element 2 and second is the member that model and performance all identicals have photosensitive property
Part, for example, photo resistance, photosensitive tube etc. can.
Above-mentioned dust cover 3 covers in whole locator to prevent falling into for dust；The present invention as needed can make base 4
Arbitrary shape is made, circle, rectangle, rhombus can be by wide popularization and applications.
The specific work process of above-mentioned sunshine mircrometer gauge is：When photovoltaic generating system is directed at sunshine, sunshine is straight
The first light-sensitive element 2 is penetrated, and blocking due to occulter 1, the second light-sensitive element 5 are among darkness.Now, first photosensitive yuan
The electric signal that part 2 exports is very big, and the second light-sensitive element 5 does not almost have signal output.When sunshine turns over 5 ° of angle, too
Sunlight is on the second light-sensitive element 5, and among the first light-sensitive element 2 is in dark, so now output signal with before
Contrast, the first light-sensitive element 2 does not almost have signal output, and the electric signal of the second light-sensitive element 5 output is very big.Pass through inspection
The change of this signal measured, tracks of device generation action can control to rotate, until the second light-sensitive element is returned to shady place,
First light-sensitive element 2 is again by sun light direct beam, and photovoltaic generating system realigns sunshine, then tracks of device stops operating, complete
Into a secondary tracking.This process constantly repeats with the movement of the sun, it is achieved thereby that the single shaft tracking apparatus moment tracks
The purpose of sunshine.
The preferred embodiment for the present invention is explained in detail above in conjunction with accompanying drawing, but the invention is not restricted to above-mentioned implementation
Mode, can also be on the premise of present inventive concept not be departed from those of ordinary skill in the art's possessed knowledge
Make a variety of changes.
Many other changes and remodeling can be made by not departing from the spirit and scope of the present invention.It should be appreciated that the present invention is not
It is limited to specific embodiment, the scope of the present invention is defined by the following claims.
