The invention pertains to control device for tracking the sun solar energy collector. Its construction is based on the principle of rotation around the polar axis. The device consists of a motor-gearbox, a potentiometer, the voltage generator with linearly increasing voltage depending on the time of a day, a generator and the potentiometer block for voltage reference - amplification. The motor-gearbox secondary shaft is connected with the solar collector and the potentiometer's driving axis. The output voltage electric circuits of the potentiometer and the voltage generator are connected to the input voltage electrical circuits of the voltage reference-amplification block. The output voltage electric circuit of the voltage reference-amplification block is connected to the motor-gearbox input voltage circuit. In order to improve the device's technical parameters and to rise the collector's tracking the sun accuracy, the construction of the device was improved by connecting the potentiometer's resistor in series with variable resistor, which second clamp is connected to the voltage. The second clamp of the potentiometer is connected to the common electric circuit. In order to simplify the solar collector's orientation to the sun, the variable resistor's axis is equipped with indicator and scale, which is graduated using time equation. |
