Abstract

Aiming at the disadvantages that the solar energy battery plate can not automatically track the sun and rotate and can only generate low power, the utility model discloses a solar energy street lamp auto tracking unit which comprises a solar energy battery plate, a battery plate support, a drive shaft, a motor, a photosensitive probe and a control circuit. The utility model is characterized in that the solar energy battery plate is ensured to automatically track the sun and rotate along with the sun, thus light application time is extended, illumination intensity is increased, the generated energy of the solar energy battery plate is improved by one or two times and the solar energy utility rate is improved.

Description

The solar street light autotracker

Technical field

The utility model discloses a kind of solar street light autotracker, can be extensively at street lamp, garden lamp, use in illumination such as Landscape Lamp place.

Background technology

Known solar street light includes light fixture, and solar panel, battery board bracket, battery etc. are fixed on solar panel on the battery board bracket, make fixing device of solar generating, for the street lighting electricity consumption.The solar street light of this existing self-contained battery plate defective in use is that solar panel can not be followed the tracks of sun rotation, sun initial rise, whereabouts or when casting oblique rays on, solar panel can not be directly to shining upon, so generated energy is less, solar energy utilization ratio is low.

Summary of the invention

Existing solar panel can not be from the defective that the motion tracking sun rotates, generated energy is low in application at the solar street light of existing self-contained battery plate, the utility model discloses a kind of solar street light autotracker, the solar panel of this device can rotate from the motion tracking sun, improves the generated energy of solar panel.

Taked following technical scheme for realizing the purpose of this utility model:

Make a kind of solar street light autotracker, this autotracker comprises solar panel, battery board bracket and lamp stand, battery board bracket is fixed on the power transmission shaft, is fixed with photosensitive probe on solar panel, is fixed with the driving controlling organization in lamp stand.

Photosensitive probe described in the utility model comprises base plate, is fixed with case on base plate, is fixed with dividing plate in case, is fixed with light-sensitive cell on the base plate of dividing plate both sides.

Driving controlling organization described in the utility model comprises the motor that is fixed in the solar energy lamp stand, be connected in the power transmission shaft between motor and the solar-cell panel support, the control circuit of control motor operation, the utility model is that solar panel is fixed on the power transmission shaft by solar-cell panel support, power transmission shaft by bearing fixing in sleeve; Solar-cell panel support is connected with motor by power transmission shaft, and the equation of light variation control motor of control circuit root a tree name photosensitive probe is done just (instead) rotation, thereby drives just (instead) rotation of solar panel.

The utility model has the advantages that simple in structurely, easy to manufacture, use easy to maintenance.

Good effect of the present utility model is that automatically tracing sun by solar cell panel is rotated, prolong light application time, increased intensity of illumination, make the generated energy of solar panel improve about one to two times, average comprehensive electric generating amount improves about 50%, has reduced the comprehensive electric generating cost.

Specific embodiments

As shown in Figure 1, solar panel 1 is fixed on the battery board bracket 6, and photosensitive probe 5 is fixed on the battery board bracket 6; Battery board bracket 6 is fixed on the power transmission shaft 2, and power transmission shaft 2 is fixed on the bearing 12, and bearing 12 is fixed in the sleeve 13; Sleeve 13 is fixed together with lamp stand 4 usefulness screws.Motor 3 is fixed in the lamp stand 4, and motor 3 is connected with power transmission shaft 2; Motor 3 can drive battery board bracket 6 by power transmission shaft 2 and do positive and negative rotation, thereby drives solar panel 1 positive and negative rotation.Control circuit is installed in the control box 8, and the output OUT1 of control circuit is connected with motor 3 with OUT2; The input IN1 of control circuit is connected with photosensitive probe 5 with IN2, and control circuit is by the storage battery power supply that is fixed on below the lamp stand 4.

Fig. 2 is circuit theory diagrams of the present utility model, and photosensitive probe 5 is made up of two light-sensitive cell G1 and G2 among the figure, and the positive pole of light-sensitive cell G1 and G2 is connected on the input IN1 and IN2 of single-chip microcomputer IC, and the negative pole of light-sensitive cell G1 and G2 connects public ground; When solar light irradiation is on light-sensitive cell G1, the voltage that light-sensitive cell G1 produces is greater than the voltage of G2, single-chip microcomputer IC output OUT1 is a high level, (UT2 is a low level) to transistor T 1, makes transistor T 1 conducting through current-limiting resistance R1, thereby make relay J 1 adhesive, normal battle of the J1-1 closure of relay J 1, motor 3 is just changeing, and rotates to a side thereby drive solar panel 1; Otherwise, when solar light irradiation is on light-sensitive cell G2, the voltage that light-sensitive cell G2 produces is greater than the voltage of G1, and single-chip microcomputer IC output OUT2 is a high level, (UT1 is a low level), this high level through current-limiting resistance R2 to transistor T 2, make transistor T 2 conductings, thereby make relay J 2 adhesives, normal battle of the J2-1 closure of relay J 2, motor 3 counter-rotatings are rotated to opposite side thereby drive solar panel 1; When the intensity of illumination of two light-sensitive cell G1 and G2 was the same, then single-chip microcomputer IC output OUT1 and OUT2 exported high level simultaneously, transistor T 1 and T2 conducting simultaneously, and relay J 1 and J2 adhesive simultaneously, 3 on motor stops operating.Evening, single-chip microcomputer IC output OUT1 and OUT2 be the while output low level then when all hanging down when the intensity of illumination of two light-sensitive cell G1 and G2, and transistor T 1 and T2 end simultaneously, relay J 1 and not adhesive of J2, and 3 on motor stops operating.

Fig. 3, Fig. 4 are the structural representation and the electrical schematic diagrams of photosensitive probe 5, and 9 among the figure is base plates of photosensitive probe 5, is fixed with case on base plate 9, and case is a transparent casing; In case, be fixed with dividing plate J1, on the base plate 9 of dividing plate 11 both sides, be fixed with light-sensitive cell G1 and G2; Light-sensitive cell G1 and G2 can produce 0.5 volt voltage after meeting light, and the operation principle of its circuit as previously mentioned.
