[0049] 100 Hydropower Generation System DETAILED DESCRIPTION

[0050] In order to further understand the structure, features, technical means and specific effects to be achieved of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0051] like Figures 1 to 5As shown in the figure, a water power multiple power generation system is disclosed, which is suitable for being arranged on a flow channel 10 of a river and rotating in a water flow direction 101. The water power multiple power generation system 100 comprises: a frame assembly 1, which is fixedly arranged on the flow channel 10; an impeller unit 2, which is arranged in the frame assembly 1 and is axially connected to the frame assembly 1 and is located in the water flow direction 101, and the impeller unit 2 comprises a transmission shaft 21 that can rotate around its own axis and a plurality of boxes arranged on the outer edge of the transmission shaft 21, which can drive the transmission shaft 21 to rotate and can be driven to rotate by the flowing water. type blades 22; at least one power generation device 3, which is arranged at a corner in the frame assembly 1; and at least one speed increase device 4, which is arranged at one end of the impeller unit 2, and the speed increase device 4 includes a driving wheel 41 coaxially arranged with the transmission shaft 21 and a passive wheel 42 correspondingly arranged at one end of the power generation device 3 and connected to the driving wheel 41, the transmission shaft 21 is used to drive the driving wheel 41 to rotate, and then drive the passive wheel 42 to rotate through the driving wheel 41, so as to increase the speed of the impeller unit 2 and drive the power generation device 3 to operate and generate electricity.

[0052] Among them, through the setting of the impeller unit 2, the power of the water flow can be effectively converted into mechanical energy, and then the speed is increased by the speed-increasing device 4 and the generated power is accelerated and transmitted to the power generation device 3, so that it obtains the corresponding speed, so that the efficiency of the power output of the power generation device 3 can be improved, thereby supplying more electricity and greatly reducing the cost of power generation.

[0053] Secondly, the hydroelectric power generation system 100 is designed to be small in size and simple in structure, so it can be installed in wide waterways or waterways of small width, thereby providing flexible applicability. It is not only easy to assemble and maintain, and has low manufacturing costs, but also does not require large-scale environmental modifications or be restricted by geographical locations. Therefore, it is suitable for use in various regions, thereby greatly expanding the scope of application of hydroelectric power generation.

[0054] In the above, the frame assembly 1 is composed of a left frame 11 and a right frame 12 disposed at both ends of the impeller unit 2 and a plurality of connecting rods 13 disposed between the left frame 11 and the right frame 12 and connected to the two.

[0055] Among them, through the arrangement of the left frame 11, the right frame 12 and the connecting rod 13, the structural stability and firmness of the hydropower generation system 100 are enhanced, ensuring the stability of the impeller unit 2 during operation, and maintaining stability even under conditions of strong or irregular water flow. In addition, it also makes installation and maintenance work easier to facilitate repair or replacement of parts.

[0056] Secondly, the design of the frame set 1 enables the water multiplier power generation system 100 to be installed in waterways of different sizes, allowing users to make appropriate adjustments according to the specific conditions of the installation environment to achieve the possibility of wide application.

[0057] like Figure 3 As shown, the driving wheel 41 and the driven wheel 42 are rotating components, and the driving wheel 41 is composed of a first plate 411, a second plate 412, and a plurality of first arms 413 connected between the first plate 411 and the second plate 412 and spaced apart from each other; and the driven wheel 42 is composed of a rotating shaft 421 disposed at one end of the power generation device 3 and connected to the power generation device 3, and a second arm 422 extending outward from the periphery of the rotating shaft 421 and being driven to rotate by the first arm 413; in this way, the driving wheel 41 can achieve the highest speed-increasing effect of the power generated by the impeller unit 2 under the action of water power and transmit it to the power generation device 3 so that it obtains a corresponding rotation speed to achieve hydroelectric power generation and generate more electric energy.

[0058] It should be particularly noted that when the driving wheel 41 is implemented in conjunction with a plurality of the power generation devices 3 , the driven wheel 42 at one end of the power generation device 3 is disposed in a one-to-one manner corresponding to the driving wheel 41 .

[0059] like Figures 3 to 5 As shown, the box-type blade 22 also includes a blade body 221, a frame-shaped side panel 222 arranged around the outside of the blade body 221, and a water outlet 223 located in the frame-shaped side panel 222 and on the same side as the blade body 221. The frame-shaped side panel 222 is constructed to be approximately L-shaped when viewed in cross section, and is used to enclose the upper and lower ends and the outer end of the blade body 221, leaving only an outlet 223 at the inner end of the blade body 221 for drainage. The blade body 221 and the water outlet 223 are arranged on the same side of the frame-shaped side panel 222, and a counterweight 5 is also provided on one side of the bottom end of the box-type blade 22.

[0060] Among them, the setting of the frame-shaped side plate 222 helps to control the path of water flow through the blade body 221, so that the water flow can be concentrated on the blade body 221, so as to improve the efficiency of the blade body 221 being pushed by hydraulic force, and at the same time effectively reduce energy loss; in addition, the frame-shaped side plate 222 also provides additional structural support to enhance the stability and durability of the impeller unit 2.

[0061] Secondly, by providing the water outlet 223 , the resistance caused by the water flow on the surface of the blade body 221 is reduced, thereby improving the rotation efficiency of the impeller unit 2 .

[0062] Furthermore, the provision of the counterweight 5 can ensure the stability of the impeller unit 2 in the water flow, especially under strong flow conditions, which helps prevent the impeller unit 2 from excessively shaking or flipping.

[0063] like Figure 4 and Figure 5 As shown, the number of box-shaped blades 22 of the impeller unit 2 is at least six or more.

[0064] Among them, the design of using six or more box-type blades 22 can increase the contact area between the impeller unit 2 and the water flow to obtain more water flow energy, thereby improving the power generation efficiency. In addition, it also helps to disperse the pressure of the water flow on a single box-type blade 22, reduce the wear caused by the impact of the water flow, and extend the service life of the water-multiplier power generation system 100. Finally, the configuration of six or more box-type blades 22 allows the operator to effectively adjust and optimize the performance of the water-multiplier power generation system 100 according to different flow rates and waterway conditions, thereby providing good flexibility and adaptability.

[0065] like Figure 6 As shown, the power generation device 3 is also rectified by an AC-DC converter 6, and then controlled by a charge and discharge controller 7 to stably input the power to a power storage device 8. The power storage device 8 is also electrically connected to a DC-AC converter 9, and the DC power is converted into AC power suitable for general AC loads by the DC-AC converter 9; in this way, the power generated by the power generation device 3 can be stored in the power storage device 8, and the power storage device 8 redistributes the electric energy and makes proper use of it, such as self-production and self-use or selling it back to the power grid.

[0066] Of course, the above description is only a specific embodiment of the present invention and is not intended to limit the scope of implementation of the present invention. Any equivalent changes or modifications made according to the structure, characteristics and principles described in the patent application scope of the present invention should be included in the patent application scope of the present invention.
