There is due to solar energy the features such as spatter property, recyclability, safety and popularity, developing into full generation
The important component part of boundary's green energy resource.The maximally effective Land use systems of solar energy is solar electrical energy generation, in particular with the sun
Photovoltaic generation can be carried out.In photovoltaic generating system, if the lighting equipment of solar panel can remain and incident illumination
Vertically, i.e. increase solar energy tracking device, it is possible to collect solar energy to greatest extent, improve solar energy utilization ratio.But mesh
Mostly front automatic sun tracking device in solar photovoltaic power plant is single, independent, and is the most independently configured with one
Driving means, certainly will make to control relatively costly, and maintenance is the biggest.Certainly also there is part to achieve solar panel and follow the tracks of dress
The coordinated signals put, but it is confined to the coordinated signals of single row (column), from having produced the example of model machine, or carry out
The domestic roof solar power station of Demonstration Construction, is all that sun tracker less for single-machine capacity is carried out one-dimensional linkage control
System forms the solar power station of relatively high power output.If making according to same principle or large-scale solar power station in design,

In existing known technology, numerous implementation methods for single automatic solar energy tracking device, conventional two drivings
Device realizes the tracking of Bearings tracking and elevation angle respectively, the kind of drive many employings electric pushrod, gear, motor etc.,
Also part prior art is had to achieve the linkage tracking using a driving means to realize azimuth and elevation angle, such as publication number
CN 102183966 A " a kind of linkage-type two-degree-of-freedom solar energy tracking mechanism " proposes to use turbine and worm transmission to realize orientation
The solar energy tracking at angle, realizes elevation angle by variable length connecting rod simultaneously and follows the tracks of with azimuth synchronous interaction approximation.If setting up
The solar power station of relatively high power output, then need this type of traditional automatic solar energy tracking device of greater number to add, and
Require that each of which is followed the tracks of configuration configures the driving means of respective numbers one by one, also exists driving means number many, on-road efficiency
Low, that production cost, installation cost, maintenance are high problem.
In order to reduce the solar-tracking cost in photovoltaic plant, under conditions of not changing tracking accuracy, scientific and technical research
The synchronous interaction that person proposes to use the fewest driving means to realize multiple tracking device is followed the tracks of.Compare more single tracking device,
The linkage of multiple tracking devices is followed the tracks of due to the movement interference etc. between its drive mechanism complexity, linkage stability, tracking device
The existence of realistic problem, its implementation difficulty comparatively speaking is a lot.From published technology, most implementation method is pin
The linkage of multiple tracking devices that " yi word pattern " extends distribution is followed the tracks of, and this type of tracking device is all that one-dimensional linkage is followed the tracks of,
Such as publication number CN 205142103 U " a kind of linking solar energy tracking system and solar power system ", CN204290838
U " a kind of adjustable connecting-rod formula solar energy tracking support ", CN 105450155 A " a kind of adjustable connecting-rod formula solar energy tracking support "

Column solar energy tracking device ", CN 103744433 A " array type solar tracking device " and CN104300887 " combination connection
The light-operated automatic tracks sunlight device of dynamic formula photovoltaic generation ", use chain or link transmission, it is achieved that array or combination type solar
Cell panel tracing control, adapts to tiling and is arranged on roof, it is achieved solar electrical energy generation on a small scale.But all can only realize one-dimensional side
The coordinated signals of parallactic angle." array type solar tracking device " its driving chain is arranged horizontally, and chain is easy to fall off, causes one
Dimension links unsuccessfully.
Multiple lines and multiple rows solar energy tracking device array two degrees of freedom linkage implementation method the most considerably less, it has been disclosed that public affairs
Know that technology is as follows:

Follow the tracks of, although simple in construction, but bearing capacity is little, it is desirable to single condenser overall dimensions is little, light weight, is only suitable for being arranged on
The place on roof, owing to using angled manner linkage to follow the tracks of sun altitude, can cause sun altitude following range limited, and
When the increase of array quantity causes an edge lengths in parallel-crank mechanism also can increase, easily cause connecting rod in certain journey
Produce the flexural deformation being difficult to discover on degree, thus affect tracking accuracy.
