Embodiment
The concrete structure of one embodiment of the invention is described below in conjunction with the accompanying drawings：
Single shaft sun tracker group of the present invention, the sun tracker that Fig. 1, the embodiment shown in 2 form for three rotating shafts 5
Group, each single shaft sun tracker are provided with the row photovoltaic panel of three row two.Whole device is arranged on support frame 1, and support frame 1 wraps
Include three fore-stocks 101 and three after-poppets 102, between front and back support and per pack support between fixed by square tubes soldering.
Bearing block 4 is installed respectively on above-mentioned front and back support, there is difference in height between described front and back support, the bearing block on front and back support
Installed in opposite directions with the inclination angle that relative ground is certain, three rotating shafts 5 are also included in the present apparatus, the both ends of rotating shaft 5 are cylindric, and centre can
Square tube can also be used with identical with the shape at both ends, square tube is comparatively cheap, and is easily installed it in square tube
His mechanism.
Two cylindrical ends of rotating shaft 5 are separately mounted in the bearing block 4 of front and back support, above-mentioned front and back support difference in height
Size, and the size at the angle of inclination of front and back support top chock is that rotating shaft 5 is inclined with respect to ground after ensureing that rotating shaft 5 is installed
Angle is parallel with earth's axis.Three photovoltaic board mounting stands 9 are also equipped with each rotating shaft 5, described mounting bracket 9 is cross bar,
The centre of cross bar is fixed in rotating shaft 5, and the both ends of cross bar can be bolted with the bolt hole of photovoltaic back.Above-mentioned
Each rotating shaft 5, which extends downwardly, is fixedly mounted vertical pull bar 8, and a drag link 6 extends to the other end by the vertical pull bar 8 of one end
Vertical pull bar, the bottom of each vertical pull bar 8 and described drag link 6 are be hinged by linkwork 7.Described linkwork 7
Including two side plates for being fixedly mounted on drag link 6, the vertical bottom of pull bar 8 is extended to inside two side plates of linkwork 7, and one
Individual jointed shaft passes through two side plates and the bottom of vertical pull bar 8.It will be evident that described linkwork 7 can be any common
Linkwork, it finally can cause vertical pull bar 8 to be rotated around the jointed shaft of the linkwork 7.
Single shaft sun tracker as described above, includes the drive mechanism of a rotating shaft 5, and the drive mechanism includes electricity
Machine 2 and decelerator 3, described decelerator 3 are arranged on the hull outside of the bearing block of any one support, and decelerator 3
Output shaft is extended to inside bearing block, is connected by shaft coupling with the cylindrical end of the side of rotating shaft 5.The input shaft installation of decelerator 3
The motor 2.
Single shaft sun tracker group as described above, after whole device installs, rotating shaft 5 parallel to earth's axis,
Photovoltaic plate array 10 rotates the tracking realized to track of sun around rotating shaft 5.3 rotating shafts 5 are completed to drive by a motor 2
Dynamic, its driving process is：Motor 2 starts, and after the deceleration of decelerator 3, drives rotating shaft 5 to rotate, the rotational band turn axle 5 of rotating shaft 5
The vertical pull bar 7 of lower section is swung, and because vertical pull bar 7 and drag link 6 are be hinged, therefore drag link 6 is in the oscillatory forces of vertical pull bar 7
Under effect, drag link 6 is also swung, final to drive the vertical pull bar 7 of other two to swing, and the swing drives other two to turn again
Axle 5 rotates.
It should be appreciated that the above-mentioned purpose of decelerator 3 is to increase the driving torque of motor 2, if the decelerator 3 using
Worm type of reduction gearing can then provide drive mechanism auto-lock function while moment of torsion is improved, i.e., when whole device is static,
Prevent because outside cause（Wind）And invert.It is fixedly mounted on it is of course also possible to which motor and decelerator are made as into an entirety
The outside of bearing block 4.
The present embodiment is the effect that three rotating shafts 5 form, it will be apparent that, every single shaft with more than two rotating shafts 5 is too
Positive tracks of device group can use the system.
Each group of the photovoltaic plate array 10 of the present embodiment arranges comprising three rows two, can significantly expect, each group can be
One big photovoltaic panel, the photovoltaic plate array 10 that embodiments of the present invention should not be limited in embodiment, however, by every group
The wind resistance that photovoltaic plate array 10 is arranged to the mode of multiple lines and multiple rows is especially good, can be used for the big desert area of spacious wind.
What deserves to be explained is, above-described embodiment is to drive three rotating shafts 5 by a drive mechanism while rotate in addition, this
The innovative point of invention be can by less drive mechanism and meanwhile drive multigroup single shaft sun tracker the sun is carried out with
Track, pass through the replacing to photovoltaic plate array 10, it is possible to achieve different application of the invention, such as：Photovoltaic plate array 10 is changed
It is used for reflecting focal sunshine for settled date planar mirror array；Photovoltaic plate array 10 is replaced with into fresnel lens array to can be achieved
Higher generating efficiency.
