[0030] Specifically, all four photovoltaic panels 5 are synchronously electrically connected, and the right-side photovoltaic panel 5 is electrically connected to the energy storage battery pack 4 via a power inverter conversion circuit. By installing angle sensors on the back of the photovoltaic panels 5, data can be used to calculate and control the angle adjustment mechanism based on the sun's position and the angle sensor data, thereby achieving automatic adjustment of the photovoltaic panel angle.

[0031] In this embodiment, the angle adjustment mechanism includes an adjustment box 9 disposed outside the rotating shaft 6 and a driven gear 12 fixedly connected to the outside of the rotating shaft 6. A reduction motor 10 is fixedly installed inside the adjustment box 9, and a transmission gear 11 that meshes with the driven gear 12 is fixedly connected to the output shaft of the reduction motor 10. By setting up the rotating shaft 6, connecting frame 7, and fixing frame 8, the photovoltaic panel 5 is fixed and supported, ensuring the stability and safety of the entire structure. The reduction motor 10 is started by the PLC controller to drive the transmission gear 11 to rotate, so that the rotation of the transmission gear 11 meshes with the driven gear 12 and drives the rotating shaft 6 to rotate, which facilitates the rotation of the photovoltaic panel 5 around the axis of the rotating shaft 6, thereby changing the angle of the photovoltaic panel 5.

[0032] The rotating shaft 6 is rotatably connected to the inside of the regulating box 9, and the inside of the regulating box 9 is fixedly installed with a bearing that is compatible with the rotating shaft 6.

An adjustment box 9 is fixedly connected to the top of the movable sleeve 16. The servo motor 14 is started by the PLC controller to drive the screw 15 to rotate, so that the movable sleeve 16 drives the adjustment box 9 and the photovoltaic panel 5 to move upward, ensuring that the photovoltaic panel 5 always faces the sun and maximizing the solar energy collection efficiency.

[0035] The screw 15 is rotatably connected to the inside of the mounting cylinder 13, which is a hollow cylinder. The inside of the mounting cylinder 13 has a moving port that is adapted to the moving sleeve 16.

[0038] The working principle of the above embodiments is as follows:

[0039] In use, the PLC controller starts the geared motor 10 to drive the transmission gear 11 to rotate. The rotation of the transmission gear 11 meshes with the driven gear 12, causing the rotating shaft 6 to rotate. This facilitates the rotation of the photovoltaic panel 5 around the axis of the rotating shaft 6, thereby changing the angle of the photovoltaic panel 5. The PLC controller starts the servo motor 14 to drive the screw 15 to rotate, causing the moving sleeve 16 to move the adjusting box 9 and the photovoltaic panel 5 upwards, ensuring that the photovoltaic panel 5 always faces the sun and maximizes the solar energy collection efficiency. By setting up the heat pump 3, the heat in the low-temperature heat source inside the energy storage tank 1 is raised and used for domestic hot water and heating. Through the combined use of the photovoltaic panel 5 and the energy storage battery pack 4, more solar energy is converted into electrical energy, directly driving the heat pump 3 to operate, improving the overall performance and energy efficiency ratio of the equipment.
