[0024] The following is combined with Figures 1 to 3 A specific embodiment of the combined wind-solar-storage power generation system of the present invention is described below: like Figure 1 As shown, an embodiment of the present invention provides a combined wind-solar-storage power generation system, mainly comprising an energy rectification and storage unit, a stacking and combining mechanism, a column 6, and three sets of wind and solar power generation units. The three sets of wind and solar power generation units are vertically stacked together, with the bottom set fixedly connected to the column 6. Adjacent sets of wind and solar power generation units are interconnected through the stacking and combining mechanism, achieving vertical stacking of multiple sets of wind and solar power generation units 3. This reduces the footprint of the combined wind-solar-storage power generation system and improves resource utilization efficiency. Each set of wind and solar power generation units 3 is electrically connected to the energy rectification and storage unit 1. After rectification, transformation, and storage of the electrical energy converted by each wind and solar power generation unit 3, it can be transmitted to an external power supply system. A platform 7 can also be provided on the column 6, allowing the energy rectification and storage unit to be placed on it. It can also serve as a foothold for maintenance personnel to inspect the power generation system, improving the convenience of maintenance work. Furthermore, facilities such as 5G signal transmission equipment 8 can be installed on the platform 7 to expand its functionality.

[0025] The power rectification and storage unit 1 may include a power rectification controller 11 and a battery pack 12. The power rectification controller 11 is electrically connected to each group of wind and solar power generation units 3, and rectifies and transforms the power converted by each group of wind and solar power generation units 3, and then transmits the rectified and transformed power to the battery pack 12 for storage.

[0026] In this embodiment, the superimposed combination mechanism 2 can be composed of multiple sets of connecting rods 21 and connecting blocks 22. The connecting rods 21 can be set around each set of wind and solar power generation units 3 and each set of connecting rods 21 is fixedly connected to the wind and solar power generation unit 3. Adjacent sets of connecting rods 21 are connected by connecting blocks 22. Such a ball joint combination mechanism can be combined into a suitable combination according to the surrounding environment during the construction process, making the application scenarios more flexible.

[0027] like Figure 2As shown, fastening mechanisms 4 can be provided at both ends of the connecting rod 21, and the connecting block 22 is provided with fixing holes 5 corresponding to the fastening mechanisms 4 to achieve mutual fixation between the connecting rod 21 and the connecting block 22. In this embodiment, the connecting rod 21 is a hollow structure with through holes at both ends. The fastening mechanism 4 includes a telescopic screw 41, a spring 42, a spring washer 43, and a fastening sleeve 44. A nut can be provided at one end of the telescopic screw 41 and embedded in the inner cavity of the connecting rod 21, and the other end is threaded and extends outward through the through hole. The fastening sleeve 44 can be sleeved on the threaded end of the telescopic screw 41. The spring washer 43 is provided between the connecting rod 21 and the fastening sleeve 44. One end of the spring 42 can be connected to the spring washer 43, and the other end can be connected to the telescopic screw 41. When the spring 42 is in the released state, the threaded end of the telescopic screw 41 protrudes out of the fastening sleeve 44; when the spring 42 is in the compressed state, the threaded end of the telescopic screw 41 retracts into the fastening sleeve 44. A positioning block 45 may also be provided on the telescopic screw 41 and connected to the spring 42 through the positioning block 45. A positioning groove 46 corresponding to the positioning block 45 is provided on the fastening sleeve 44 to ensure that the telescopic screw 41 can rotate when the fastening sleeve 44 rotates.

[0028] When installing the connecting rod 21 and the connecting block 22, the telescopic screw 41 can be retracted into the fastening sleeve 44 by pressing the telescopic screw 41 or sliding the positioning block 45 in the positioning groove 46. At this time, the spring 42 is in a compressed state. When the telescopic screw 41 moves to the corresponding fixing hole position on the connecting block 22, the telescopic screw 41 is released and pops outward. Then, the fastening sleeve 44 can be rotated with a wrench or other tools to drive the telescopic screw 41 to rotate. When rotating, the telescopic screw 41 can be screwed into the fixing hole through the thread, realizing the connection between the connecting rod 21 and the connecting block 22. When disassembling, simply unscrew the telescopic screw 41 out of the fixing hole and retract the telescopic screw 41 into the fastening sleeve 44 by sliding the positioning block 45 in the positioning groove 46 to realize the disassembly between the connecting rod 21 and the connecting block 22. This node-type structure makes the stacked combination mechanism 2 easier to install, disassemble, and maintain.

[0029] like Figure 3As shown, the wind and solar power generation unit 3 in this embodiment can be composed of a wind turbine 31, a mounting frame 32, and solar photovoltaic panels 33. The wind turbine 31 can be a vertical axis wind turbine, capable of receiving wind energy from multiple directions. The mounting frame 32 can be arranged around the wind turbine 31 to fix its position. The solar photovoltaic panels 33 can be arranged along the edge of the mounting frame 32, and multiple solar photovoltaic panels 33 can collectively form a funnel shape, with the smaller side of the funnel close to the wind turbine 31. This allows for wind concentration while collecting solar energy, improving wind energy utilization efficiency. Alternatively, the solar photovoltaic panels 33 can be transparent double-sided solar photovoltaic panels or semi-transparent double-sided solar photovoltaic panels to further improve solar energy utilization efficiency.

[0030] In addition, the combined wind, solar and energy storage power generation system provided in this embodiment is prismatic in shape. In other embodiments, the combined wind, solar and energy storage power generation system may also be cylindrical or tower-shaped. By freely combining the connecting rods 21 and the connecting blocks 22, a suitable superposition combination method can be selected according to different usage scenarios.

[0031] The combined wind-solar-storage power generation system of this invention has the following advantages: simple structure and convenient maintenance. The stacked combination method of this invention fully utilizes vertical space, reducing the floor space occupied by the power generation system. Furthermore, the storage platform mounted on the columns facilitates maintenance work, improving ease of maintenance. In addition, the uniquely designed wind and solar power generation units can simultaneously receive wind and solar energy from multiple directions, effectively improving energy utilization efficiency.

[0032] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
