Description

Technical Field

[0001] This invention relates to the field of wave energy power generation technology, and in particular to a wave energy power generation platform wave-absorbing floating structure. Background Technology

[0002] Wave power generation uses the energy of waves to produce electricity. Ocean waves contain enormous energy. Through a certain device, the energy of the waves can be converted into mechanical, pneumatic, or hydraulic energy, which is then used to drive a generator to produce electricity through a transmission mechanism, gas turbine, water turbine, or hydraulic motor.

[0003] Wave energy generation devices are transported to a sea area by tow to convert ocean waves into green electricity, thereby achieving a stable power supply to the islands.

[0004] The wave energy hydraulic energy conversion system is an intermediate process for transferring wave energy to electrical energy. It can be regarded as the load end of wave energy and the input end of electrical energy. The hydraulic system uses the waves absorbed by the wave-absorbing float of the wave energy generator as a power source to drive the hydraulic cylinder connected to the generator to do work. During the reciprocating motion of the hydraulic cylinder, energy is stored in the form of pressure energy in the hydraulic oil, and the hydraulic oil is delivered to the energy storage unit. When the pressure of the hydraulic oil reaches the set value, it begins to release, driving the hydraulic motor to rotate and drive the generator to generate electricity, thereby realizing the conversion of wave energy into electrical energy.

[0005] Chinese invention CN202210782717.0 discloses a bottom-mounted hydraulic wave energy generating float, comprising a float body, a spring-returning hydraulic cylinder, an anchor chain, and an energy conversion device. The bottom of the float body is connected to the top of the cylinder in the spring-returning hydraulic cylinder via a steel cable. The piston rod of the spring-returning hydraulic cylinder extends downward and is fixed to the seabed via the anchor chain. The hydraulic oil circuit in the spring-returning hydraulic cylinder is connected to the hydraulic pipeline in the energy conversion device, and the output end of the hydraulic pipeline is connected to the hydraulic motor generator in the energy conversion device. The hydraulic oil circuit in the spring-returning hydraulic cylinder is connected to an oil tank. Utilizing the float body, the spring-returning hydraulic cylinder, and the energy conversion device, the system gradually realizes the conversion from ocean wave energy to float mechanical energy, from float mechanical energy to hydraulic energy, and from hydraulic energy to electrical energy during the movement of the entire system.

[0006] The aforementioned floating body is connected to a hydraulic cylinder via steel cables. Because the steel cables are not perfectly rigid, the energy transmitted from the floating body to the hydraulic cylinder is affected by the platform's undulations, thus limiting energy transfer. Furthermore, the shape of the floating body makes it difficult to fully utilize wave energy. The combined effect of these two factors results in the overall power generation efficiency of the power platform failing to meet expectations. Summary of the Invention

[0007] This invention aims to at least address the technical problems existing in the prior art, namely, that "the floating body is connected to the hydraulic cylinder by steel cables. Because the steel cables are not perfectly rigid, the energy transferred from the floating body to the hydraulic cylinder is affected by the platform's undulations, thus limiting energy transfer. Furthermore, the shape of the floating body makes it difficult to fully utilize wave energy, and the combined effect of these two factors results in the overall power generation efficiency of the power generation platform failing to meet expectations."

[0037] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0038] The following is for reference. Figures 1-7 The wave-absorbing floating structure of the wave energy power generation platform according to an embodiment of the present invention is described.

[0039] like Figures 1-7As shown, the wave energy power generation platform's wave-absorbing floating structure is mainly used in wave energy power generation devices. It includes a wave energy power generation platform 100, which is equipped with a hydraulic device 400 and a floating device shaft 200. Specifically, it includes a floating device rocker arm 300 and a wave-absorbing floating structure 500, with the rocker arm 300 rotatably connected to the floating device shaft 200. The rocker arm 300 is a rigid structure, unlike existing cable structures. The length of its lever arm is not affected by the undulations of waves or ocean currents, thus ensuring that the transmission efficiency is not affected during energy conversion.

[0040] The wave-absorbing floating structure 500 is connected to the rocker arm 300 of the floating device. One side of the wave-absorbing floating structure 500 is connected to the push rod of the hydraulic device 400. When the wave-absorbing floating structure 500 is pushed by waves or ocean currents, the wave-absorbing floating structure 500 and the rocker arm 300 of the floating device rotate around the rotating shaft 200 of the floating device. The wave-absorbing floating structure 500 pushes the push rod of the hydraulic device 400 to work, causing compression within the hydraulic cylinder, thereby converting mechanical energy into hydraulic internal energy, which is then converted into electrical energy by the hydraulic device 400. The power generation principle of the wave energy power generation device is a well-known technical solution to those skilled in the art and will not be described in detail in this embodiment.

[0041] The wave-absorbing float structure 500 has a streamlined, eagle-head-shaped structure. The wave-absorbing float structure 500 and the float device rocker arm 300 are welded together to form a rigid connection. This reduces energy loss during the rotation of the wave-absorbing float structure 500 around the float device rocker arm 300 and the compression of the hydraulic device 400, thereby effectively improving the energy conversion efficiency of the power generation device. The wave-absorbing float structure 500 and the float device rocker arm 300 of this invention can reduce the decrease in power generation efficiency caused by wave fluctuations, making the wave energy power generation device more stable and efficient.

[0042] In some embodiments of the present invention, such as Figure 1 As shown, the wave-absorbing floating structure 500, the floating device rocker arm 300 and the hydraulic device 400 form a set of power generation units, and at least one set of power generation units are arranged on the wave energy power generation platform 100.

[0043] Specifically, multiple power generation units can be arranged on the wave energy power generation platform 100 at the same time. The specific number of units is determined by the size of the wave energy power generation platform 100. All power generation units are arranged side by side, thereby improving the stability of the wave energy power generation platform 100 and increasing the power generation efficiency.

[0044] In some embodiments of the present invention, the wave-absorbing floating structure 500 is made of ship-grade steel, at least Grade A steel. Specifically, ship-grade steel is divided into four grades: A, B, C, and D. These four grades of steel have a yield strength of not less than 235 N / mm² and a tensile strength of 400–520 N / mm², but their impact toughness varies at different temperatures. The specific steel grade used in the wave-absorbing floating structure 500 is determined based on the actual operating sea area of ​​the wave energy power generation platform 100. The present invention does not elaborate on the ship-grade steel grades used in the wave-absorbing floating structure 500. It should be understood that, without departing from the basic concept of the present invention, any flexible changes in the ship-grade steel grades used in the wave-absorbing floating structure 500 should be considered within the scope of protection defined by the present invention.

[0045] In some embodiments of the present invention, such as Figure 2 As shown, the overall shape of the wave-absorbing float structure 500 is linear and smooth, in the form of an arc, which is used to improve the wave absorption effect of the wave-absorbing float structure 500 in waves and ocean currents, and improve the power generation efficiency. The diameter of the wave-absorbing float structure 500 is R1 1100mm~1200mm, R2 30000mm~33000mm, R3 1000mm~1200mm, R4 25000mm~26000mm, R5 900mm~1100mm, and R diameter 10000mm~12000mm.

[0046] Based on the diameter range of R1, R2, R3, R4, R5 and R6, the overall shape of the wave-absorbing floating structure 500 can be made similar to the upright shape of an eagle's head, that is, the wave-absorbing floating structure 500 is shaped like an eagle's head, which conforms to hydrodynamics and can be more easily propelled by waves or ocean currents, thereby improving energy conversion efficiency and making more efficient use of wave energy to generate electricity.

[0047] Specifically, R1 has a diameter of 1160mm, R2 has a diameter of 31900mm, R3 has a diameter of 1000mm, R4 has a diameter of 26000mm, R5 has a diameter of 1000mm, and R6 has a diameter of 11300mm.

[0048] It should be understood that the selected diameters of R1, R2, R3, R4, R5, and R6 are not the only implementation method. In some other embodiments, the diameters of R1, R2, R3, R4, R5, and R6 can be arbitrarily selected and combined within a defined range. This invention does not elaborate on the selected diameters and combinations of R1, R2, R3, R4, R5, and R6 one by one. It should be understood that, without departing from the basic concept of this invention, flexible variations in the selected diameters and combinations of R1, R2, R3, R4, R5, and R6 should all be considered within the protection scope defined by this invention.

[0049] In some embodiments of the present invention, such as Figures 3-5 As shown, in order to reduce the overall weight of the wave-absorbing floating structure 500 and improve its overall structural strength, various reinforcing ribs need to be installed inside the wave-absorbing floating structure 500, and local reinforcing structures need to be installed in different parts of the wave-absorbing floating structure 500. It is also necessary to make the wave-absorbing floating structure 500 a closed structure so that it can capture more wave energy when waves push it to rotate, thereby improving the overall power generation efficiency of the wave energy power generation platform 100.

[0050] Specifically, the microwave absorbing float structure 500 has a float platform 507 inside, which divides the interior of the microwave absorbing float structure 500 into upper and lower parts. The upper part of the interior of the microwave absorbing float structure 500 has a lower sealing plate 503, a front end plate 501, an upper sealing plate 502, an outer plate longitudinal girder 509, and a rear end plate 505. The lower part of the interior of the microwave absorbing float structure 500 has a lower sealing plate 503, a lower end plate 506, a rear sealing plate 504, and an outer plate longitudinal girder 508.

[0051] The two side walls of the microwave absorbing float structure 500 are connected by a lower sealing plate 503, a front end plate 501, an upper sealing plate 502, an outer plate longitudinal truss 509, a rear end plate 505, a lower end plate 506, a rear sealing plate 504, and an outer plate longitudinal rib 508. This increases the structural strength of the microwave absorbing float structure, prevents deformation of the outer shell of the microwave absorbing float structure 500 under long-term use, avoids affecting power generation efficiency, and extends service life.

[0052] In some embodiments of the present invention, such as Figures 3-5 As shown, the microwave absorbing floating structure 500 has an internal reinforcing rib structure, which includes a strong rib web 510 and a vertical stiffener 511. The strong rib web 510 and the vertical stiffener 511 are welded together. The strong rib web 510 is distributed at the upper and lower ends of the floating platform 507. One end of the strong rib web 510 is welded to the floating platform 507, and the other end is welded to the front end plate 501, the upper sealing plate 502, the lower sealing plate 503, the rear sealing plate 504, the rear end plate 505, and the lower end plate 506, forming the eagle head frame structure of the microwave absorbing floating structure 500.

[0053] Specifically, various vertical reinforcing ribs are added inside the wave-absorbing float structure 500 to improve the longitudinal structural strength of the wave-absorbing float structure 500 and prevent the wave-absorbing float structure 500 from deforming longitudinally due to wave impact.

[0054] In some embodiments of the present invention, such as Figures 3-5As shown, the internal structure of the wave-absorbing floating body 500 includes a transverse wall structure, comprising transverse wall plates 512 and transverse wall stiffeners 513. The transverse wall stiffeners 513 are welded to the reinforcing rib web plates 510. The transverse wall plates 512 are distributed along the upper and lower ends of the floating platform 507. The transverse wall plates 512 are welded to the front end plate 501, upper sealing plate 502, lower sealing plate 503, rear sealing plate 504, rear end plate 505, and lower end plate 506, respectively, forming a rigid frame structure of the wave-absorbing floating body 500. This connects the internal structure and outer plates of the wave-absorbing floating body 500 to form a sealed frame structure, which is used to improve the overall strength of the wave-absorbing floating body 500 and reduce its overall weight.

[0055] Specifically, various lateral reinforcing ribs are added inside the wave-absorbing float structure 500 to enhance its lateral structural strength and prevent lateral deformation due to wave impact. The wave-absorbing float structure 500 is connected by these lateral and longitudinal reinforcing ribs, which improves overall structural strength while reducing the amount of internal steel used, effectively lowering the overall weight of the wave-absorbing float structure 500.

[0056] In some embodiments of the present invention, the reinforcing rib web 510 and the transverse wall plate 512 are respectively made of sheet metal. Alternatively, the vertical stiffeners 511 and the transverse wall stiffeners 513 are made of flat steel or bulb flat steel. Alternatively, the outer plate longitudinal stiffener 508 is made of bulb flat steel. It should be understood that, without departing from the basic concept of the present invention, the types of materials used for the reinforcing rib web 510, transverse wall plate 512, vertical stiffeners 511, transverse wall stiffeners 513, and outer plate longitudinal stiffener 508 can be flexibly varied, and all such variations should be considered within the scope of protection defined by the present invention.

[0057] In some embodiments of the present invention, such as Figure 6 and Figure 7 As shown, the upper sealing plate 502 is welded to the transverse wall plate 512 and the outer plate longitudinal ribs 508, respectively, and the spacing d between the outer plate longitudinal ribs 508 is 500mm to 700mm. The outer plate longitudinal girders 509 adopt a T-shaped composite beam structure, and the outer plate longitudinal girders 509 are welded to the upper sealing plate 502, with a spacing c between the outer plate longitudinal girders 509 being 2d to 4d. The strong rib web plates 510 are welded to the upper sealing plate 502, and the spacing between the strong rib web plates 510 is b1 or b2, with spacing b1 being 3d to 6d and spacing b2 being 3d to 6d.

[0058] Different spacing d is selected according to the different dimensions of the wave-absorbing floating structure 500, thereby adjusting the layout of the reinforcing components of the overall structure, so that the connection strength of each position of the overall structure is maintained and the service life is improved.

[0059] In some embodiments of the present invention, such as Figure 6 and Figure 7As shown, the rocker arm 300 of the floating device is equipped with an upper shaft arm, which is welded to the upper sealing plate 502. The spacing between the upper shaft arms is 9d to 18d. Welding the upper shaft arm to the upper sealing plate 502 can increase the connection strength between the wave-absorbing floating structure 500 and the rocker arm 300 of the floating device, and prevent the connection between the wave-absorbing floating structure 500 and the rocker arm 300 from loosening due to long-term wave impact.
