Detailed Implementation
[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. In this specification, "multiple" refers to two or more.
[0023] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or illustrative embodiment of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.
[0024] Reference Figures 1-4 As shown, this utility model embodiment provides a wave power generation device, including a power generation mechanism 1 fixed to the upper end of the seabed, a connecting component 2 provided at the upper end of the power generation mechanism 1, a float 3 provided at the upper end of the connecting component 2, and the float 3 floating on the sea surface.
[0025] The power generation mechanism 1 includes a shell 11 and a power generation component 15. The shell 11 is fixedly connected to the upper end of the seabed. A flow channel 12 is vertically opened inside the shell 11. Water inlet holes 13 are opened on both the front and rear sides of the flow channel 12. The power generation component 15 is installed inside the flow channel 12. The power generation component 15 is used to convert mechanical energy into electrical energy. When working, the float 3 moves up and down with the rise and fall of the waves. The connecting component 2 causes pressure changes in the water flow in the flow channel 12. The water flow enters the flow channel 12 through the water inlet holes 13 and drives the power generation component 15 to operate, thereby converting mechanical energy into electrical energy and realizing the effective utilization of wave energy.
[0026] In a further embodiment, refer to Figures 2-3 A first one-way valve 121 is fixedly connected inside the flow channel 12 located between the power generation component 15 and the water inlet 13. A second one-way valve 131 is fixedly connected inside the water inlet 13. The power generation component 15 includes a generator 155 and an impeller 152. A rotating shaft 151 is rotatably connected inside the flow channel 12 via a mounting bracket. The impeller 152 is fixedly connected to the side wall of the rotating shaft 151. A first bevel gear 153 is fixedly connected to the lower end of the rotating shaft 151. The generator 155 is fixedly connected to the front and rear sides inside the housing 11. A second bevel gear 154 is fixedly connected to the output shaft end of the generator 155. The second bevel gear 154 meshes with the first bevel gear 153. Water outlet holes 14 are opened on both the front and rear end faces of the lower side of the housing 11. The water outlet holes 14 are connected to the flow channel 12.
[0027] In this embodiment, the first one-way valve 121 and the second one-way valve 131 ensure unidirectional water flow, allowing water to enter the flow channel 12 only through the inlet hole 13. The water then drives the impeller 152 to rotate through the connecting component 2, preventing backflow and thus improving power generation efficiency and ensuring the stability of the power generation process. The impeller 152 is connected to the first bevel gear 153 via the rotating shaft 151. The first bevel gear 153 meshes with the second bevel gear 154 at the output shaft end of the generator 155. This gear transmission structure effectively transmits the rotational motion of the impeller 152 to the generator 155, achieving efficient conversion of mechanical energy into electrical energy. Meanwhile, the outlet hole 14 on the lower side of the outer casing 11 is connected to the flow channel 12, allowing the water flowing through the impeller 152 to be discharged smoothly, ensuring smooth water circulation inside the flow channel 12 and further optimizing the working performance of the power generation device.
[0028] In a further embodiment, refer to Figure 2 The connecting component 2 includes a sleeve 21 and a piston 22. The sleeve 21 is fixedly connected to the upper end of the outer shell 11, and the inside of the sleeve 21 is connected to the flow channel 12. The piston 22 is slidably connected to the inside of the sleeve 21, and a push rod 23 is fixedly connected to the piston 22. The upper end of the push rod 23 is fixedly connected to the lower end of the float 3.
[0029] In this embodiment, by setting up a connecting assembly 2 consisting of a sleeve 21 and a piston 22, effective linkage between the float 3 and the power generation mechanism 1 is achieved. When the float 3 moves up and down with the rise and fall of the waves, it drives the push rod 23 to move synchronously, thereby pushing the piston 22 to slide inside the sleeve 21. The movement of the piston 22 causes pressure changes in the water flow inside the sleeve 21, thereby driving the water flow in the flow channel 12 to drive the impeller 152 in the power generation assembly 15 to rotate, thereby driving the generator 155 to generate electricity. This not only efficiently transfers the mechanical energy of the waves to the power generation mechanism 1, but also ensures the stability and continuity of the power generation process, further improving the utilization efficiency of wave energy.
[0030] In a further embodiment, refer to Figure 4 A dovetail block 32 is fixedly connected to the left end of the float 3, and a dovetail groove 31 is opened on the right end face of the float 3. The dovetail block 32 is located inside the dovetail groove 31 of the adjacent float 3 on the left and is slidably connected to it.
[0031] In this embodiment, the dovetail block 32 at the left end of the float 3 and the dovetail groove 31 at the right end cooperate with each other to form a sliding connection structure. This not only enhances the connection stability between the floats 3, but also ensures that the float 3 can slide smoothly along a predetermined trajectory under the action of waves, avoiding misalignment or damage to the float 3 caused by wave impact. At the same time, the float 3 is made of high-strength corrosion-resistant material, which can effectively resist salt spray corrosion and wave impact in the marine environment, extend the service life of the equipment, reduce maintenance costs, and improve the reliability and durability of the equipment in complex marine environments.
[0032] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
