Embodiment
Below in conjunction with accompanying drawing, structural principle of the present invention and principle of work are described in further detail.
Referring to Fig. 1, a kind of condensation photovoltaic tracking means, include solar energy photovoltaic panel 1, solar energy photovoltaic panel 1 is fixed on photovoltaic panel installing support 2, it is characterized in that, photovoltaic panel installing support 2 is connected with pitch axis 7, pitch axis 7 is outer is provided with pitch axis axle sleeve 8, and pitch axis 7 is connected with transverse axis 3, and transverse axis 3 is connected with horizontal revolving stage 4, horizontal revolving stage 4 is connected with horizontal servo motor 6, and horizontal revolving stage 4 has support post 5 with horizontal servo motor 6.
Referring to Fig. 2, pitching on described transverse axis 3 and pitch axis axle sleeve 8 drives box 10 and is connected, pitching drives in box 10 and is provided with pitching servomotor 11, pitching servomotor 11 is connected with worm screw 13 by wheel box 12, worm screw 13 is meshed with pitch axis 7, worm screw 13 is provided with nut 14, is provided with expansion link 9 between nut 14 and pitch axis 7, is provided with unidirectional baffle plate 15 between nut 14 and expansion link 9.
Described transverse axis 3, horizontal revolving stage 4 and horizontal servo motor 6 form horizontal adjusting mechanism.
Described pitch axis 7, pitch axis axle sleeve 8, expansion link 9, pitching drive box 10, pitching servomotor 11, wheel box 12, worm screw 13, nut 14 and unidirectional baffle plate 15 and form aligning elevation gear.
The transverse axis lower end is connected with horizontal revolving stage, and the upper end is connected with the pitch axis axle sleeve; Above-mentioned horizontal revolving stage inner ring is connected with transverse axis, and outer rim is dentation, is subjected to driven by servomotor; Above-mentioned aligning elevation gear comprises that pitch axis, pitch axis axle sleeve, expansion link, pitching drive box, pitching servomotor, wheel box, worm screw, nut and unidirectional baffle plate; Above-mentioned pitching drives box and the welding of pitch axis axle sleeve; Above-mentioned pitching servomotor is arranged on pitching and drives bottom box, rotates by wheel box speed change rear drive worm screw; There is unidirectional baffle plate on above-mentioned worm screw top, and it passes the nut center pit, and with nut center hole wall on threaded engagement; Above-mentioned nut outer rim and expansion link welding; Above-mentioned expansion link top and pitch axis are hinged, can be around bearing rotary; Appeal support post bottom is bolted on large ground, and whole system is supported in the upper end.
The present invention controls transverse axis and pitch axis and unites the driving solar energy photovoltaic panel over against the sunshine incident ray according to the program of prior input.Usually in use, when sun light intensity reaches the collection standard, programmed control horizontal drive Electric Machine Control horizontal revolving stage rotates, horizontal revolving stage rotarily drives transverse axis and rotates, the orientation angles that solar energy photovoltaic panel is forwarded to set, the pitching of programmed control simultaneously drive motor rotates through wheel box rear drive worm screw, rotate the control expansion link by worm screw and elongates or shortens, can drive the pitch axis rotation, the luffing angle of adjusting solar energy photovoltaic panel arrives preset value.This moment, solar energy photovoltaic panel was over against the sunshine incident direction.Fall along with the east of the sun rises the west, program is united driving by controlling two motors, makes the interlock of pitch axis and transverse axis, guarantees that solar energy photovoltaic panel follows the tracks of the sunshine incident direction constantly.
Its specific works process is: calculate and the pen recorder location sun altitude in some time in such a month, and on such a day according to above-mentioned formula, utilize these data to write pitch axis 7 drivers; The driving of transverse axis 3 to guarantee solar energy photovoltaic panel 1 sunny slope all the time with solar direction in same plane, this can be by celestial coordinates and the movement locus of record solar and the earth, programming realizes.when the sun rises to certain altitude, when illuminance satisfies predetermined value, system starts working, the programmed control horizontal drive motor 6 of finishing is in advance controlled horizontal revolving stage 4 and is rotated, horizontal revolving stage 4 rotarily drives transverse axis 3 and rotates, make solar energy photovoltaic panel 1 forward the orientation angles that sets to, the pitching of programmed control simultaneously drive motor 11 rotates through wheel box 12 rear drive worm screws 13, because the screw-threaded engagement on worm screw 13 and nut 14 center hole walls, so will drive nut 14 moves up and down along worm screw 13, nut 14 and expansion link 9 welding, and then expansion link 9 is elongated or shortened, again because expansion link 9 is hinged with pitch axis 7, so can drive pitch axis 7 rotations by changing expansion link 9 length, the final angle of pitch of adjusting solar energy photovoltaic panel 1, make it over against the sunshine incident direction.Fall along with the east of one day sun rises the west, by the control of program, pitch axis 7 and transverse axis 3 interlocks guarantee that solar energy photovoltaic panel 1 follows the tracks of the sunshine incident direction constantly.In the whole course of work, the current direction of unidirectional baffle plate 15 is from top to bottom, can prevent that expansion link 9 breaks away from pitching when rising and drives box 10, causes equipment failure.After the sun fell, two motor-driven transverse axis 3 of programmed control and pitch axis 7 forwarded rapidly the initial measuring position of second day to.
The above; only embodiments of the invention; be not that the present invention is imposed any restrictions, every any simple modification, change and equivalent structure of above embodiment being done according to the technology of the present invention essence changes, and all still belongs in the protection domain of technical solution of the present invention.
