Major advantage of the present utility model is:
1) the such as controlling unit that when, abandoning traditional, the photovoltaic tracking control structure of casement and light-operated is brought is complicated, Installation and Debugging are complicated, device is various and even the not high shortcomings of reliability.The utility model adopts one piece of main photovoltaic panel power resources as direct-drive motor being arranged on solar panel light lateral plates place, with light lateral plates each other oppositely and the left photovoltaic panel in all vertical main photovoltaic panel plate face and right photovoltaic panel formed and turned to correction source.When main photovoltaic panel and solar panel and sunlight angle inconsistent time, it is different that left photovoltaic panel and right photovoltaic panel receive solar radiation, at least have a plate export direct current and make corresponding relay produce energized action, and then one of them relay switch making homopolarity be communicated with produces disconnection or the closed action of " time delay ", make direct-drive motor obtain electric startup thereupon connection drive circuit, the final photovoltaic array that drives rotates.And when left photovoltaic panel and right photovoltaic panel and sunlight light ray parallel, it is identical that it receives solar radiation, relay all can not action, and drive circuit disconnects all the time, and motor also would not rotate.
On said structure basis, some emphasis is had to should be noted that: first, as with solar panel in the same way and the main photovoltaic panel be arranged in parallel, as long as solar panel is accurate towards sunray all the time, the optical efficiency that is subject to of main photovoltaic panel is just in maximization all the time, its light is sufficient, and generation current is large, makes direct current machine M supply of electric power sufficient.Secondly, have employed drive circuit and the distinct design of control circuit, non-interference each other between direct-drive motor and differential concatenation battery pack.Direct-drive motor can not produce long-time weak current circulation phenomenon because connecting differential concatenation battery pack all the time, also just do not exist and generate heat and the problem of Damage to insulation.Finally, differential concatenation battery pack two ends only need to drive relay coil, and load is light, power is little, it is little to bear reverse current; Battery pack can not produce overheating conditions, and reliability is high, long service life.In addition, by adopting deferred action relay, dependence arranges suitable delay time, after making it obtain electric a period of time, corresponding relay switch side produces corresponding actions, the motor caused because system responses is too sensitive effectively can be avoided constantly to produce useless forward and backward action because the water surface jolts, and then be conducive to the actual life of lifting motor and mechanical structure.
2), specific to the assembly structure of each photovoltaic panel, the utility model provides a kind of succinct implementation: adopt the boxlike control box of four square box shapes to construct; By arranging corresponding photovoltaic panel in the front of this control box and left and right sides, thus realize front and provide direct-drive motor power supply and side forms the object of reverse Stringing cells group.Box structure integraty is strong, and be convenient to carrying and assembling, the parts such as circuit can directly arrange in the sealing box body of control box, thus avoid the corrosion of briny environment, and job security is higher, and useful life also can be ensured further.
3), for the restriction of the light lateral plates area of each photovoltaic panel, ensure that the fast and reliable response of control circuit first; Opposite side then make use of more large-area main photovoltaic panel, thus provides the more reliable electric power of direct-drive motor to transform and supply effect.
4), for the realization of the concrete driving function based on solar panel, maybe can adopt existing continental rise or float type frame mode, only need improve the control circuit of its drive motors.As adopted traditional bearing structure, relying on the modes such as drive motors forward and backward driven gear driving, guaranteeing the rotation needs of corresponding solar panel.And the utility model provides following two kinds of concrete execution modes:
A, adopt circular floating pedestal, the circulus of what solar panel was skewed be positioned at floating pedestal, and utilize floating pedestal horizontally rotating along its anchor ring axis, realize the rotational action of solar panel.Now, drive drive circuit according to aforesaid control circuit and then direct current machine generation is turned to accordingly, thus driving driving wheel to produce the stone roller action of relatively floating pedestal inner ring surface.Along with the rotation of driving wheel, the floating pedestal inner ring surface of plane or anti-slip veins or tooth bar cooperation with it produces rotation thereupon, and then drives whole floating pedestal to produce just to the rotational action in solar light irradiation direction together with solar panel.
In said structure, the structure being the rod-pulling type of employing main, coordinates each Compress Spring, thus the tight face realizing corresponding wheel body and floating pedestal is against coordinating.Simultaneously, the Compress Spring at driving wheel place, thus guarantee that driving wheel fits tightly demand based on floating pedestal.And utilize the Compress Spring between two pressing plates being located in pull bar shaft, then while meeting above-mentioned laminating demand, serve the buffering absorbing object of the adjacent floating pedestal when floating pedestal rotates or seawater bounces especially, thus make whole solar cell panel assembly not by the floating shock effect of seawater.Said structure is succinctly reasonable, and without the need to the seawater buffer technology of complexity, use cost and effect all can effectively be ensured.
B, prism between upper pillar stand and lower pillar stand be free to slide socket mode, ensure that the liftable effect of solar panel, specific motor of arranging in pairs or groups, it can be made to possess the self-regulation effect of following seawater ebb tide flood tide.In other words, between upper pillar stand and lower pillar stand, be only slide over each other socket without any control assembly, tide fluctuation, upper pillar stand can rise and fall thereupon, thus ensures that solar panel is in more than sea all the time and locates.And the layout of panoramic table, then the direct-drive motor that the utility model of can directly arranging in pairs or groups is above-mentioned, so meet controlledly targetedly turn to regulatory demand
