The exemplary embodiments that embodies the utility model feature & benefits will describe in detail in the following description.It should be understood that the utility model can have various variations on different embodiment, it neither departs from scope of the present utility model, and explanation wherein and accompanying drawing be when the use that explain in itself, but not in order to limit the utility model.
The solar energy tracking support of the utilization two dimension obliquity sensor of the utility model embodiment, comprises solar bracket, two-dimentional obliquity sensor and monitoring center's composition.
Solar bracket 1 can be all in the market one dimension or two-dimensional tracking supports.
The present embodiment is introduced with two-dimensional tracking support, but the utility model is not as limit.Solar bracket 1 has girder 7, secondary beam 8, the first dimension angle regulating device and the second dimension angle regulating device.
Wherein, all circular tube structures preferably of girder 7 and secondary beam 8, girder 7 is that solar panel 3 carries out the turning axle that the first dimension elevation angle is adjusted, secondary beam 8 is that solar panel 3 carries out the turning axle that the second dimension elevation angle is adjusted.Girder 7 is supported by column 5.Solar panel 3 can be the combination that is separately positioned on the upper and lower multipair solar cell panel unit of girder 7, on girder 7, vertically connect pivotable multiple secondary beams 8 by anchor ear, also be that secondary beam 8 rotates in anchor ear again, therefore the rotation of girder 7 can drive the rotation of secondary beam 8, but the rotation of secondary beam 8 can not drive girder 7.On each secondary beam 8, be fixedly connected with four crossbeams, be respectively used between two fixing girder 7 two solar cell panel unit one on the other.
As known from the above, the parts such as girder 7, secondary beam 8 wherein, are the parts of the framework of fixing and support solar cell panel 3, also participate in adjusting the elevation angle of solar panel 3 simultaneously.
Wherein, as shown in Figure 1, the first dimension elevation angle regulation device comprises connecting rod 12, push rod 13 and motor 11; As shown in Figure 2, Fig. 2 be the B of Fig. 2 to view, for clarity sake, 3 middle of solar panels have been shown in broken lines profile, the second dimension elevation angle regulation device comprises main transmission bar 23, gangbar 22, inferior drive link 26, push rod 21 and motor 20.
The first dimension elevation angle adjustment here refers to the elevation angle adjustment that solar panel 3 carries out according to seasonal variations.The second dimension elevation angle adjustment here refers to that solar panel 3 is according to sooner or later changing the elevation angle adjustment of carrying out.
Push rod 13 is driven by motor 15, and one end that push rod 13 is connected with motor 15 is articulated with connecting rod 12, and one end of push rod 13 is hinged on column 5, and the other end of connecting rod 12 is fixedly connected on girder 7.Therefore, can, in the time that push rod 13 is flexible, by connecting rod 12, drive girder 7 to rotate, drive secondary beam 8 to rotate around girder 7, the elevation angle of realizing the first dimension regulates.
For the second dimension, push rod 21 is driven by motor 20, one end being connected with motor 20 of push rod 21 is hinged on girder 7, the other end of push rod 12 is articulated with main transmission bar 23, main transmission bar 23 is fixedly connected on a wherein secondary beam 8, and then be hinged in the positive gangbar 22 arranging of solar panel 3, gangbar 22 is fixedly connected with all the other secondary beams 8 by inferior drive link 26.Therefore, can drive with the direct-connected secondary beam 8 of main transmission bar 23 and rotate, and by gangbar 22 and time drive link 26, drive all the other secondary beams 8 to rotate.Therefore, can, in the time that push rod 21 is flexible, by main transmission bar 23, gangbar 22 and inferior drive link 26, drive secondary beam 8 to rotate, the elevation angle of realizing the second dimension regulates.
Obliquity sensor 2 can adopt YHQ type two dimension obliquity sensor.Two dimension obliquity sensor 2 is arranged on the back side of solar panel 3, with solar panel 3 keeping parallelisms, data transmission cable directly leads to monitoring center, by solar energy tracking support in each dimension rotational angle data pass in real time monitoring center back, the data such as real-time position angle and elevation angle of the sun that the temporal information of being exported according to gps system by monitoring center and latitude and longitude information obtain are sent instruction automatically, control the electric pushrod 13 on solar energy tracking support, 21 move, and then promotion solar panel 3 rotates, realize the tracking of solar energy tracking support to sunshine.
The utility model can adopt step-by-step movement to look a day tracking, the running that is twin shaft support is not successional, a but given threshold value, if when the difference of current sun angle and angle of solar cell panel exceedes the threshold value of setting, restart the complete angled adjustment of two motors 11,20, so both reduce support and rotated and the energy of consumption, improved again sun power conversion efficiency.
The utility model can install two-dimentional obliquity sensor additional at the cell panel back side of mounted solar two-dimension tracking support 1, when mounted, should ensure the installed surface (being reference field) and solar panel 3 keeping parallelisms of two-dimentional obliquity sensor 2.
By the DOL Data Output Line cable of two-dimentional obliquity sensor 2 and monitoring center's wired or wireless connection of (not shown), and energising detects, after upper electro-detection, read in local time information and the latitude and longitude information exported by gps system, and calculate the data such as real-time position angle and elevation angle of the local sun.
Can be in monitoring center a given threshold value, i.e. the difference range of current sun angle and angle of solar cell panel.The difference that while calculating last rotation by monitoring center according to the angle threshold values setting, the angle of the sun changes, if this difference exceedes the threshold value of setting, send instruction by monitoring center, motor 11,20 is controlled, finally drive solar panel accurately to trace into the position of the sun.
If the difference that while calculating last rotation, the angle of the sun changes does not exceed the threshold values of setting, monitoring center will not make order, continues to monitor the rotational angle data of the solar panel of being passed back by two-dimentional obliquity sensor.
Those skilled in the art should recognize change and the retouching the scope and spirit of the present utility model that the appended claim of the utility model discloses, done in the case of not departing from, within all belonging to the protection domain of claim of the present utility model.
