[0027] The solar power generation mechanism comprises photovoltaic panels 3, a base 4 and a photovoltaic inverter, the photovoltaic panels 3 are installed on the base 4, the photovoltaic inverter is electrically connected with the photovoltaic panels 3 and the battery 205, the photovoltaic panels 3 are used to absorb solar radiation, the photovoltaic inverter is used to convert the generated direct current into alternating current and store it in the battery for use by multiple electrical appliances; the base 4 is rotatably provided with a turntable 5, the photovoltaic panels 3 are installed on the turntable 5, the periphery of the base 4 is provided with multiple illuminance sensors, the base 4 is provided with a controller and a servo motor for driving the turntable 5 to rotate, the multiple illuminance sensors can detect the solar radiation intensity at different positions and feed back signals to the controller, the controller can be controlled by a PLC controller or a microprocessor controller, when the illuminance intensity of the illuminance sensor at a certain angle position is detected to be the strongest, the photovoltaic panels 3 are driven to rotate by the servo motor, so that the photovoltaic panels 3 can receive more solar radiation.

[0028] Specifically, the water inlet pipe and the drain pipe are arranged in communication in the interior of the heat preservation water tank 1, cold water enters the interior of the heat preservation water tank 1 through the water inlet pipe and is heated by the heating copper pipe 9 to realize the heating work of the water, but because the water often contains calcium and magnesium ions, the calcium and magnesium ions combine with carbonate ions to form insoluble precipitates in the heating process of the water, and the precipitates attached to the surface of the heating copper pipe 9 can greatly reduce the heating effect of the heating copper pipe 9.

[0029] In the cleaning of the heating copper pipe 9, the servo motor 8 is arranged to drive the first threaded rod 12 to rotate, and the moving direction of the first scraper 10 can be adjusted by adjusting the rotating direction of the first threaded rod 12.

When the first scraper 10 is driven to move upward, the second scraper 11 moves from left to right. The first scraper 10 can clean the scale on the vertical pipe part of the heating copper pipe 9 and the inner wall of the heat preservation water tank 1 during the moving process. The second scraper 11 can clean the scale on the horizontal pipe part of the heating copper pipe 9 and the inner wall of the heat preservation water tank 1 during the moving process. Further, in order to facilitate the observation of the scale inside the heat preservation water tank 1, a vacuum glass is arranged on the heat preservation water tank 1.
