[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0033] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0036] The purpose of this invention is to provide a combined solar thermal and wave energy power generation device, comprising a solar thermal absorption device 1, a solar thermal power generation component 2, a medium condensation device 3, a connecting pipe 4, and a wave energy power generation component 5. The solar thermal absorption device 1 is cyclically connected to the solar power generation component 2 and the medium condensation device 3 via the connecting pipe 4, and a flow medium 41 flows within the connecting pipe 4. The solar thermal power generation component 2 is located between the outlet of the solar absorption device and the inlet of the medium condensation device 3. The flow medium 41 is heated and vaporized in the solar absorption device, and the vaporized flow medium 41 is transported to the solar thermal power generation component 2 via the connecting pipe 4. It is understood that the solar thermal power generation component 2 typically includes a turbine and a generator. The vaporized flow medium 41 drives the turbine in the solar thermal power generation component 2 to rotate through a predetermined flow pattern. The rotation of the turbine is then converted into electrical energy by the generator in the solar thermal power generation component 2, thereby generating electricity.

[0037] In addition, the medium condensation device 3 has a first flow channel 301 and a second flow channel 302 for heat transfer connection. The first flow channel 301 is configured as a channel for waves to enter. The first port of the second flow channel 302 is connected to the solar thermal power generation component 2 through the connecting pipe 4. The second port of the second flow channel 302 is provided with a third opening 303 and is connected to the inlet of the solar thermal absorption device 1 through the connecting pipe 4. The vaporized flow medium 41 is transported to the second flow channel 302 through the solar thermal power generation component 2 for cooling, and then turns back into a liquid flow medium 41. Then it returns to the solar thermal absorption device 1 through the connecting pipe 4, thereby realizing the circulation of the flow medium 41 between the solar thermal absorption device 1 and the medium condensation device 3.

[0038] In the above process, the vaporized flow medium 41 can be heat-transferred with the waves entering the first flow channel 301, so that the waves can cool the vaporized flow medium 41. At the same time, since the wave energy generation component 5 is located on the medium condensation device 3, the wave energy generation component 5 can generate electricity simultaneously when the waves enter and exit the first flow channel 301. In this way, the above configuration not only effectively improves the power generation efficiency, but also saves the need for additional devices for condensing the flow medium 41, thereby reducing manufacturing costs, simplifying the structure, and enhancing the reliability and economy of use.

[0039] Specifically, in this embodiment, reference is made to... Figure 2As shown, the solar thermal absorption device 1 includes a heat-absorbing device body 11 and a first buoyancy member 12. The heat-absorbing device body 11 has a heat-absorbing inner cavity 111 storing a liquid flow medium 41. The heat-absorbing inner cavity 111 has a first opening 1111 and a second opening 1112 at both ends. The first opening 1111 is connected to the first port of the solar thermal power generation component 2 and the second flow channel 302 through a connecting pipe 4. The second opening 1112 is connected to the second port of the second flow channel 302 through a connecting pipe 4. The first buoyancy member 12 is connected to the heat-absorbing device body 11 and can float the heat-absorbing device body 11 on the water surface to provide buoyancy support for the heat-absorbing device body 11. The setting of the first buoyancy member 12 enables the heat-absorbing device body 11 to maintain a floating state under the action of waves and can stably absorb solar energy. Optionally, the first buoyancy member 12 can be a float made of hollow foam material or a composite material buoyancy member, etc., which is not limited in this embodiment.

[0040] Specifically, in this embodiment, along the axis of the heat-absorbing device body 11 and in the direction from the first opening 1111 to the second opening 1112, the heat-absorbing device body 11 is a conical hollow structure with a gradually increasing horizontal cross-sectional area. This design effectively increases the area of ​​direct sunlight reaching the heat-absorbing device body 11, thereby increasing the heat-absorbing surface area and resulting in a more significant temperature rise. Furthermore, the flow path of the flowing medium 41 is optimized. Compared to a flat heat-absorbing device body 11, this avoids the accumulation of vaporized flowing medium 41 at the first opening 1111, allowing the vaporized flowing medium 41 to exit more reliably and efficiently from the first opening 1111, thus contributing to improved power generation efficiency.

[0041] It should be noted that in this embodiment, a low-boiling-point medium 41 is selected for the flow medium 41, which can accelerate the vaporization process. In this way, with higher heating efficiency and faster vaporization, the power generation efficiency of the solar thermal power generation component 2 can be effectively improved.

[0042] More specifically, in this embodiment, the solar thermal absorption device 1 further includes a flow guide 13. In one implementation, the flow guide 13 is a cylindrical structure, integrally formed at the first opening 1111 of the heat absorption device body 11. A flow guide channel 131 is provided through the flow guide 13. The first port of the flow guide channel 131 is connected to the first opening 1111, and the second port of the flow guide channel 131 is connected to the first port of the solar thermal power generation component 2 and the second flow channel 302 via a connecting pipe 4. By providing the flow guide 13, the vaporized flow medium 41 can be effectively guided from the first opening 1111 into the connecting pipe 4, ensuring the uniform and smooth flow of the flow medium 41, thereby improving thermal efficiency.

[0043] Optionally, the solar thermal absorption device 1 provided in this embodiment further includes an isolation member 14 and a heat insulation member 15. In one embodiment, the isolation member 14 is an annular plate and is sleeved on the top of the flow guide 13. The outer edge of the isolation member 14 is fixedly connected to the bottom of the heat absorption device body 11 to seal and cover the top of the heat absorption device body 11. The isolation member 14 is provided with a light-transmitting part, which allows the heat absorption device body 11 to absorb solar energy through the light-transmitting part, and also prevents external water vapor from contacting the heat absorption device body 11 and affecting the flow medium 41. The heat insulation member 15 is disposed between the heat absorption device body 11 and the water surface to thermally insulate the heat absorption device body 11 from the water surface and prevent heat loss to the water surface. Through the above-mentioned isolation member 14 and heat insulation member 15, the heat absorption device body 11 has good thermal insulation properties, improves the vaporization efficiency of the flow medium 41, and thus improves the power generation efficiency.

[0044] Optionally, in this embodiment, reference is made to... Figure 3 As shown, the medium condensation device 3 includes a condensation device body 31 and a second buoyancy member 32. The condensation device body 31 has the aforementioned first flow channel 301 and second flow channel 302, and a wave energy generation component 5 is installed on the condensation device body 31. The second buoyancy member 32 is connected to the condensation device body 31 to float it on the water surface. The second buoyancy member 32 ensures the stability of the condensation device body 31 on the water surface, preventing tilting and ensuring the installation stability of the wave energy generation component 5. Furthermore, it can be connected to the heat absorption device body 11 through the connecting pipe 4 to form a stable floating power generation device, thus ensuring the reliability and safety of the entire solar thermal and wave energy combined power generation device. Optionally, similar to the first buoyancy member 12, the second buoyancy member 32 can also be a float made of hollow foam material or a composite material buoyancy member, etc.

[0045] It should be noted that in this embodiment, the connecting pipe 4 between the third opening 303 and the second opening 1112 is below the water surface, so that the natural cooling effect of seawater can be used to continuously cool the flow medium 41, ensuring that the flow medium 41 is kept in a suitable temperature range before entering the heat absorption cavity 111, thereby helping to improve the thermal efficiency and stability of the system.

[0046] Furthermore, in this embodiment, reference is made to... Figure 4 As shown, a strip plate 311 protrudes from the outer side of the condenser body 31. The strip plate 311 is hollow inside and is connected to the second flow channel 302, thereby increasing the contact area between the second flow channel 302 and the waves outside the condenser body 31 and accelerating the cooling efficiency of the flow medium 41.

[0047] Preferably, in this embodiment, the horizontal cross-section of the condenser body 31 is gear-shaped, that is, multiple strip plates 311 are spaced apart along the circumferential direction on the outer side of the condenser body 31, which further increases the contact area between the second flow channel 302 and waves in the external environment, thereby meeting the cooling performance requirements of the condenser body 31 under actual working conditions. It is understood that this embodiment does not limit the number of strip plates 311.

[0048] Optionally, in this embodiment, reference is made to... Figure 1 As shown, the solar thermal and wave energy combined power generation device also includes a shading structure 6. The shading structure 6 is installed above the medium condensation device 3 to reduce sunlight exposure to the condensation device body 31, lower the temperature of the condensation device body 31, and improve cooling efficiency. Referring to existing technologies, the type of the shading structure 6 can be a shading net, shading panel, shading film, or shading canvas, etc., and this embodiment is not limited to this.

[0049] Optionally, in this embodiment, reference continues to be made to Figure 1 As shown, the solar thermal and wave energy combined power generation device also includes a solar photovoltaic power generation component 7. The solar photovoltaic power generation component 7 is attached to the top of the shading structure 6, which allows the solar thermal and wave energy combined power generation device to improve cooling efficiency through the shading structure 6, while also making reasonable use of space by placing the solar photovoltaic power generation component 7 on the top of the shading structure 6, and further improving power generation efficiency. This makes the solar thermal and wave energy combined power generation device not only have high space utilization, but also effectively improve the overall power generation efficiency and synergistic effect, so that the power generation device can maintain high operating efficiency under different environmental conditions.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention.
