Description

Energy Saving Solar Automatic Tracker

technical field

The utility model relates to an automatic tracker, in particular to an energy-saving solar automatic tracker.

Background technique

Solar energy is a kind of clean energy, which is inexhaustible and inexhaustible. Today, whether in coastal cities or inland cities, solar energy products are increasingly entering people's field of vision. Solar street lights, solar lawn lights , Solar garden lights, bus stop lamps, traffic lights and so on. However, at present, there is generally a problem of low utilization rate in terms of solar energy utilization. Especially in the field of photovoltaic power generation, due to the current photovoltaic power generation technology, the photovoltaic cells used are mainly semiconductor materials such as monocrystalline silicon and polycrystalline silicon, and the production of these materials is complicated, requires a large amount of power consumption, and is very costly. The service life is only twenty years. Therefore, making full use of solar panels, that is, improving the power generation efficiency of photovoltaic panels, has become one of the main ways to reduce the cost of solar battery power generation.

In recent years, automatic tracking of sunlight has been realized in the photovoltaic arrays of some solar power plants at home and abroad, but these devices have complex structures and consume a lot of power.

Contents of the invention

The purpose of the utility model is to provide an energy-saving solar automatic tracker. The energy-saving solar automatic tracker provides working voltage for the tracking system through the solar battery and the storage battery through the solar charge and discharge controller. The tracking system judges the intensity of the current light through the data collected by the sensor. When the light reaches a certain intensity, it judges which direction the light is stronger by comparing the data in the sensor, and transmits the data to the single-chip control system, and then controls the two through the output. The positive and negative rotation of the stepping motor is used to realize the three-dimensional tracking of solar energy.

Due to the slow change of the sun's rays, the system tracking has no obvious effect, but the system power consumption remains unchanged. In order to save unnecessary power consumption, the system is specially improved. When the system is tracked in place, the output of the control microcontroller is used to control the on-off of the mos tube. , to realize the power saving of the electric motor. After the set time, the system will track again based on the data sampled by the sensor.

The energy-saving solar automatic tracker can be used for small household solar receiving equipment such as solar street lamps and solar lawn lamps. By increasing the scale, it can be used for large-scale solar power generation.

The utility model is achieved in this way, it includes a base, a rotating rod, a horizontally rotating gear, a drive stepper motor, a worm rod, a solar panel, a stepper motor, an illumination sensor, and a controller, and is characterized in that the base is vertically connected to rotate The bottom end of the rotating rod is connected to drive the stepper motor through the horizontal rotation gear, the top of the rotating rod is matched with the worm rod, and the top of the worm rod is fixedly connected to the back of the solar panel, and the worm rod is connected to the stepping motor through the spur gear. Into the motor, the side of the solar panel is connected with a light sensor, the light sensor, the stepper motor and the drive stepper motor are respectively connected to the controller.

The technical effects of the utility model are: 1) relying on solar energy to make the tracking system work for a long time; 2) easy to use and good stability, after installation, there will be no problems for a long time. 3) Energy saving and power saving, the system can judge the disconnection of the motor through the light intensity, reducing the unnecessary power of the system.

Detailed ways

As shown in Figure 1, the utility model is realized in this way, the base 6 is vertically connected to the bottom of the rotating rod 10, the bottom of the rotating rod 10 is connected to drive the stepper motor 8 through the horizontal rotation gear 7, and the top of the rotating rod 10 Cooperate with the worm 2, the top of the worm 2 is fixedly connected to the back of the solar cell panel 1, the worm 2 is connected to the stepping motor 4 through the spur gear 3, and the side of the solar cell 1 is connected with an illumination sensor 5, The light sensor 5, the stepper motor 4 and the drive stepper motor 8 are respectively connected to the controller 9. Use the light sensor to collect light to judge the intensity of light. When it is under light, it can automatically track. When the light is blocked or it is cloudy, the tracker will not continue to track, so as to avoid the consequences that are not worth the candle. Since the sunlight does not change greatly within a certain period of time, and the tracker consumes a certain amount of electric energy to keep track, in order to save the electric energy consumed by the tracker while improving the efficiency of the solar panel a little bit, the utility model adopts the method of interval tracking, When the tracker is in place, the tracker will automatically cut off the power of the motor and stop the rotation. After the preset time, the system will automatically turn on the motor to achieve tracking. Using photosensitive diodes, the light intensity is judged by comparing the voltage on one of the diodes with a preset resistance voltage. Eight diodes are cross-connected and installed on the four sides of a pyramid-shaped wooden board. The pyramid-shaped wooden board is fixed in a hemisphere. The sphere is transparent, and the whole hemisphere is installed next to the solar panel and can rotate with the panel. The base is a rectangular piece of iron, the length and width of which can be changed within a certain range. The iron piece is fixed on the bottom of the packaging box. The control circuit is installed in the packaging box. There is a hole in the middle of the upper surface of the box through which the horizontal shaft can pass. , the horizontal gear is also packaged in the box, and one end of the box has an opening for the input of control system signals and voltages.
