Abstract
The utility model discloses a solar energy device capable of automatically following sunlight to move. The solar energy device comprises a light collection plate, a light sensing system, a control circuit and a mechanical part which enables the light collection plate to rotate. The light sensing system comprises two light sensitive resistors, wherein the two light sensitive resistors are arranged on the light collection plate respectively through a support rod; each support rod forms a 45-degree angle with the light collection plate, and the included angle between the two support rods is 90 degrees; simultaneously, the plane on which the two support rods are positioned is vertical to the rotating shaft of the mechanical part; the two light sensitive resistors are connected with the control circuit respectively; and the control circuit processes signals acquired by the light sensitive resistors and then drives the mechanical part to realize the light collection plate to automatically follow the sunlight. The solar energy device can simply and conveniently improve the utilization rate of the solar energy greatly, and enables the solar energy products to work normally in whatever seasons.
Description
Technical field
The utility model relates to a kind of solar energy equipment, relates in particular to a kind of solar energy equipment that sunshine moves of following automatically.
Background technology
Sun power has been widely used in worker, agricultural production and the family life as a kind of inexhaustible green energy resource.But the fixed installation of the plane skylight (being solar panel) of existing solar facilities can not rotate with moving of sunshine, so solar energy utilization ratio is very low.Especially in short place of sunshine-duration, solar facilities can not use substantially.
The utility model content
At the prior art above shortcomings, the purpose of this utility model just is to provide a kind of solar energy equipment that sunshine moves of following automatically, can effectively improve solar energy utilization rate.
To achieve these goals, the technical solution adopted in the utility model is such: follow the solar energy equipment that sunshine moves automatically, the mechanical part that comprises plane skylight, photosensitive system, control circuit and plane skylight is rotated, described photosensitive system comprises two photoresistance, two photoresistance are installed on the plane skylight by a pole respectively, all be 45 between two poles and plane skylight, and the angle between two poles is 90 °; Simultaneously, the plane at two pole places is vertical with the rotating shaft of mechanical part, and two photoresistance all link to each other with control circuit, and control circuit is followed the sunshine of the signal Processing rear drive mechanical part realization plane skylight of photoresistance collection automatically.
Further, described mechanical part comprises direct current generator and reductor, and the photoelectric code disk that is used to feed back the plane skylight rotational angle is housed on motor shaft.
Rotating shaft two ends at mechanical part also are equipped with mechanical limit switch, and two mechanical limit switches link to each other with control circuit.
Described control circuit comprises the driving circuit of single-chip microprocessor MCU and driving device part.
Compared with prior art, advantage of the present utility model is: be two photoresistance that miter angle is installed owing to adopted with daylighting face, when sunshine is parallel to the plane skylight normal illumination, the resistance of the photoresistance of two same specifications and model is almost equal so, when if sunshine deviates from the plane skylight normal illumination, the resistance of two photoresistance will inevitably reduce in one of an increase so, therefore, its very variation of sensitive reflection solar light irradiation angle, thereby signal is passed to single-chip microcomputer, and single-chip microcomputer is implemented accurately control by photoelectric code disk to the rotational angle of reality after calculating the angle that needs to rotate.Utilize this device to increase substantially solar energy utilization rate simply and easily, make solar product no matter can both operate as normal in what season.

Fig. 2 is the utility model schematic block circuit diagram.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment: referring to Fig. 1, Fig. 2, the utility model is followed the solar energy equipment that sunshine moves automatically, the mechanical part 2 that comprises plane skylight 1, photosensitive system, control circuit and plane skylight 1 is rotated, described photosensitive system comprises two photoresistance 3, two photoresistance 3 are installed on the plane skylight 1 by a pole respectively, 1 of two poles and plane skylight all are 45, and the angle between two poles is 90 °; Simultaneously, the plane at two pole places is vertical with the rotating shaft of mechanical part 2, and two photoresistance 3 all link to each other with control circuit, and control circuit is followed the sunshine of the signal Processing rear drive mechanical part 2 realization plane skylights 1 that photoresistance 3 is gathered automatically.
Described mechanical part 2 comprises direct current generator and reductor, and motor shaft is equipped with the photoelectric code disk 4 that is used to feed back plane skylight 1 rotational angle.
Rotating shaft two ends at mechanical part 2 also are equipped with mechanical limit switch, and two mechanical limit switches link to each other with control circuit.
Described control circuit comprises the driving circuit of single-chip microprocessor MCU and driving device part 2.
Owing to adopted with daylighting face and be two photoresistance 3 that miter angle is installed, when sunshine is parallel to plane skylight 1 normal illumination, the resistance of the photoresistance 3 of two same specifications and model is almost equal so, when if sunshine deviates from plane skylight 1 normal illumination, the resistance of two photoresistance 3 will inevitably reduce in one of an increase so, therefore, its very variation of sensitive reflection solar light irradiation angle, thereby signal is passed to single-chip microcomputer, single-chip microcomputer is gathered two photosensitive change in resistance, change the angle that corresponding plane skylight 1 needs rotation by calculating this, utilize photoelectric code disk 4 signals to implement the accurate control of plane skylight 1 rotational angle, make to rotate behind the electric motor starting to settle at one go, improved efficient greatly and realized energy-conservation.Utilize this device to increase substantially solar energy utilization rate simply and easily, make solar product no matter can both operate as normal in what season.
