[0024] In some embodiments, the photovoltaic assembly 1 includes a hollow tube 19 and a hollow ball 20. The hollow ball 20 is sleeved outside the hollow tube 19. Flexible photovoltaic films are attached to the outside of the hollow tube 19 and the hollow ball 20. The hollow tube 19 is vertically arranged and located at the center of the water ball 28.

[0025] The design of the photovoltaic assembly 1 provided in this embodiment increases the area where the photovoltaic film is laid, thereby improving the photovoltaic power generation efficiency.

[0026] In some embodiments, a photovoltaic panel 10 is fixedly disposed near the bottom of the hollow tube 19 with an angle of less than 15 degrees with the horizontal plane.

[0027] In some embodiments, the upper water pipe 9 penetrates into the water ball 28 from the bottom of the water ball 28, and the upper water pipe 9 penetrated into the water ball 28 is located in the hollow tube 19, and the top, middle and bottom of the hollow tube 19 are provided with through holes 22; four through holes 22 are provided at each position; among the four through holes 22 at each position, the axis of any through hole 22 is colinear with the axis of one through hole 22 of the other three through holes 22, and is perpendicular to the axes of the other two through holes 22, and a spray pipe 21 is inserted in the through hole 22, one end of the spray pipe 21 is inserted into the hollow tube 19 from the through hole 22 and connected with the upper water pipe 9, and the other end is located outside the hollow tube 19, and a plurality of spray holes 23 are opened on the part of the spray pipe 21 located outside the hollow tube 19.

[0028] This embodiment can make the water in the water ball 28 flow substantially in a radial direction when water is added to the water ball 28, thereby increasing the light conduction effect and enhancing the light focusing effect.

[0029] Specifically, cross-shaped through holes 22 are pre-reserved at the bottom, middle and top of the hollow tube 19 , and through holes 22 are also reserved at corresponding positions of the flexible photovoltaic film.

[0030] In some embodiments, the negative pressure water suction pipe 11 is connected to the spray pipe 21 at the top of the hollow tube 19 .

[0031] This embodiment enables the water ball 28 to achieve a spraying effect when absorbing water under negative pressure, thereby driving the water in the water ball 28 to flow.

[0032] In addition, in order to ensure automatic negative pressure water suction, the diameter of the negative pressure water suction pipe 11 should be smaller than the diameter of the flushing pipe 2 .

[0033] In some embodiments, the water ball 28 includes an upper ball and a lower ball. The upper ball is buckled on the top of the lower ball, and the upper ball and the lower ball are connected.

[0034] In some embodiments, the hydroelectric generator 4 includes a turbine 24, a generator 25, a permanent magnet turntable 26 and an arc-shaped magnet base 27. The output speed end of the turbine 24 is connected to the input end of the generator 25 through a connecting shaft. A permanent magnet turntable 26 is installed in the middle of the connecting shaft. An arc-shaped magnet base 27 is arranged on one side of the permanent magnet turntable 26. The arc-shaped magnet base 27 and the permanent magnet turntable 26 are arranged with the same pole on the side close to each other.

[0035] The permanent magnet turntable 26 and the arc-shaped magnet base 27 in this embodiment serve as a magnetic suspension assist system to increase the power generation of the hydroelectric generator 4 .

[0039] The present invention also provides a power generation system, comprising a plurality of wind, light and water integrated power generation devices as described above, wherein the water balls 28 in the plurality of wind, light and water integrated power generation devices are all connected.

[0040] This embodiment can simultaneously set up multiple wind, solar and water integrated power generation devices, thereby enhancing the power generation capacity to meet the electricity needs of different occasions.

[0041] illustrate, Figure 1 Only one implementation mode is illustrated. In actual application, the connecting portion between the top of the flushing pipe 2 and the water ball 28 can be moved downward by a certain distance so that the water in the water ball 28 can flush downward through the flushing pipe 2 under the action of gravity.

[0042] The wind, light and water integrated power generation device provided by the present invention has the following multiple specific application implementations.

[0043] 1. Single-machine implementation. That is, a wind, light, and water integrated power generation device. The designed hydropower / wind power / photovoltaic installed capacity ratio of the single machine is: 5-10 / 5 / 2, the installed capacity is 12 kilowatts or 17 kilowatts, and the area is 4 square meters, which is equivalent to the power generation and area occupied by about 21-31 550W photovoltaic panels. If the three installed capacity ratios of hydropower (annual power generation of 15,000 degrees / annual power generation and utilization of 3,000 hours), wind power generation (annual power generation of 10,000 degrees / annual power generation and utilization of 2,000 hours), and photovoltaic power generation (annual power generation of 2,000 degrees / annual power generation and utilization of 1,000 hours) are used, it can supply about 2-3 7kw AC charging piles and 1-2 60kw DC charging piles. If two wind, light, and water integrated power generation devices are connected in series in parking spaces, landscape leisure areas, especially in remote rural areas, pastoral areas, and scenic areas, 6 7kw charging piles can be guaranteed.

[0044] 2. Network collection mode. That is, multiple wind, light, and water integrated power generation devices are installed. If a megawatt-scale power generation network is formed, it is only necessary to connect the middle of the water ball 28 in series with a pipeline to form a large grid water body interconnected in the air, about 59-84 water balls 28, and adopt overall water level control for centralized circulation. First, natural streams can be introduced to circulate, store, work, and discharge in large water bodies, and second, clean water is concentrated for storage, circulation, and work. Centralized circulation requires the establishment of water collection circulation and reasonable pipe network distribution facilities, such as grid distribution, which is specifically determined by the planned terrain. In short, it is land-saving and efficient. At present, the cost budget for implementing the present invention is close to the lowest price of photovoltaic bidding (0.645 yuan / watt). Third, in the centralized large-scale water body circulation-storage-work, the specifications and quantity of wind power generation and hydropower generation can be changed, the number of generators can be reduced, the power of generators can be increased, the installed power can be increased, and the installation cost can be reduced. At the same time, the aerial grid is used to increase the number of photovoltaic installations to achieve a cluster effect.

[0045] 3. Power supply for the electrolytic hydrogen industry and the high-computing AI industry. The equipment investment of the present invention is less than 8 million yuan, and can achieve megawatt-level cluster power supply. In the electrolytic hydrogen industry, in addition to the large investment in PEM (proton exchange membrane water electrolysis) technology equipment (30 million yuan), the production of one cubic meter of hydrogen consumes 4.5 degrees of electricity, and the hydrogen production per hour ranges from a few cubic meters to dozens of cubic meters. The corresponding power demand is generally tens of kilowatts to hundreds of kilowatts, which is enough to support two hydrogen production companies. 70% of its operating costs are electricity charges. If the electricity charge drops to 2 yuan / kWh (the current electricity price is 4 yuan / kWh), the development of hydrogen energy will have obvious competitive advantages, and the use of natural energy for power generation will have obvious cost competitive advantages.

[0046] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
