Solar water heating device capable of automatically tracking sunlight

The invention relates to the technical field of solar water heating devices, and discloses a solar water heating device capable of automatically tracking sunlight, the solar water heating device comprises a main body mechanism, an adjusting mechanism and a cleaning mechanism, the adjusting mechanism is located at the upper end of the main body mechanism, and the cleaning mechanism is located at the outer end of the adjusting mechanism. According to the solar water heating device capable of automatically tracking the sunlight, the first photoelectric sensor and the second photoelectric sensor are electrically connected with the controller, and when the light irradiation amount received by the first photoelectric sensor and the second photoelectric sensor is different, namely, the mounting substrate is not perpendicular to the sunlight; therefore, currents transmitted to a controller by a first photoelectric sensor and a second photoelectric sensor are different in magnitude, the controller starts an electric p
