Description

Technical Field

[0001] This invention relates to a mechanical equipment, and more particularly to a wave energy power generation device. Background Technology

[0002] Currently, common wave energy generation devices include fixed-base point absorbers and floating-base point absorbers. Fixed-base point absorbers require the base to be fixed to the seabed to work, making them unsuitable for deeper waters and less adaptable to different sea conditions. Floating-base point absorbers, while not requiring the base to be fixed to the seabed and suitable for use in deep water, are heavier and more difficult to fix. Furthermore, both types of point absorbers primarily convert wave energy in the vertical direction through buoyancy, failing to fully utilize the energy generated in other directions, resulting in a lower wave energy conversion rate. Summary of the Invention

[0003] The purpose of this invention is to provide a wave energy power generation device that is more adaptable to different sea conditions and has a higher wave energy utilization rate.

[0004] To address the aforementioned technical problems, this application provides the following technical solution:

[0005] This invention discloses a wave energy generation device, comprising a fixed platform, a floating body, a central shaft connector, at least one set of first energy conversion elements, and at least two sets of second energy conversion elements. The fixed platform is fixed to the seabed or suspended at a certain distance above the sea surface. The floating body floats on the sea surface. Each first energy conversion element includes a first pressure cylinder body and a first pressure cylinder piston rod. The first pressure cylinder body is vertically arranged, with its closed end connected to the fixed platform. One end of the first pressure cylinder piston rod is disposed within the first pressure cylinder body, and the other end is connected to the central shaft connector. The floating body is annular, and the central shaft connector is located at the center point within the annulus of the floating body. The second energy conversion element includes a second pressure cylinder body and a second pressure cylinder piston rod. The closed end of the second pressure cylinder body is connected to the inner wall of the float. One end of the second pressure cylinder piston rod is disposed inside the second pressure cylinder body, and the other end is connected to the central shaft connector. Two sets of the second energy conversion elements are arranged at intervals. The second pressure cylinder body is adapted to rotate relative to the float in a horizontal plane, and the second pressure cylinder piston rod is adapted to rotate relative to the central shaft connector in a horizontal plane. Both the first pressure cylinder body and the second pressure cylinder body are provided with an energy conversion medium. The energy conversion medium is connected to a generator, and the energy conversion medium is used to drive the generator to generate electricity.

[0006] In the wave energy generation device of the present invention, the second pressure cylinder body and the float body are respectively connected by a first rotating joint and a second rotating joint.

[0007] The wave energy generation device of the present invention, wherein the fixed platform is a disc with a certain thickness.

[0008] The present invention relates to a wave energy generation device, wherein the floating body is a circular ring with a certain thickness.

[0009] The wave energy generation device of the present invention, wherein the central shaft connector is a cube, the second energy conversion element is provided in four sets, and the connection point between the piston rod of the second pressure cylinder and the central shaft connector is located on one side of the cube.

[0010] The wave energy generation device of the present invention, wherein the first pressure cylinder body and the second pressure cylinder body are both hydraulic cylinders.

[0011] Compared with existing technologies, the wave energy generation device of the present invention includes a fixed platform, a floating body, a central shaft connector, one or more sets of first energy conversion elements, and two or more sets of second energy conversion elements. Each second energy conversion element includes a second pressure cylinder body and a second pressure cylinder piston rod. The closed end of the second pressure cylinder body is connected to the inner wall of the floating body, and one end of the second pressure cylinder piston rod is disposed within the second pressure cylinder body and the other end is connected to the central shaft connector. The second pressure cylinder body is adapted to rotate relative to the floating body in a horizontal plane, and the second pressure cylinder piston rod is adapted to rotate relative to the central shaft connector in a horizontal plane. This ensures that the energy generated by waves in multiple directions can cause relative motion between the floating body and the central shaft connector, or relative movement between the central shaft connector and the floating body, thereby converting wave energy into electrical energy, greatly improving the utilization rate of wave energy. Furthermore, because the fixed platform is fixed to the seabed or suspended at a certain distance from the sea surface, the wave energy generation device of the present invention is applicable not only to shallow water areas but also to deep water areas, exhibiting better adaptability to different sea conditions, and has a simple structure.

[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the present invention discloses a wave energy generation device, comprising a fixed platform 11, a float 12, a central shaft connector 13, one or more sets of first energy conversion elements, and two or more sets of second energy conversion elements. The fixed platform 11 is fixed to the seabed or suspended at a certain distance from the sea surface. The float 12 floats on the sea surface. The first energy conversion elements include a first pressure cylinder body 14 and a first pressure cylinder piston rod 15. The first pressure cylinder body 14 is vertically arranged, and its closed end is connected to the fixed platform 11 by fasteners. One end of the first pressure cylinder piston rod 15 is disposed inside the first pressure cylinder body 14, and the other end is connected to the central shaft connector 13 by fasteners. The float 12 is an annular body, and the central shaft connector 13 is provided with... At the center point inside the ring of the float 12, the second energy conversion element includes a second pressure cylinder body 16 and a second pressure cylinder piston rod 17. The closed end of the second pressure cylinder body 16 is connected to the inner wall of the float 12. One end of the second pressure cylinder piston rod 17 is located inside the second pressure cylinder body 16, and the other end is connected to the central shaft connector 13. The two sets of second energy conversion elements are arranged at intervals. The second pressure cylinder body 16 is adapted to rotate relative to the float 12 in the horizontal plane, and the second pressure cylinder piston rod 17 is adapted to rotate relative to the central shaft connector 13 in the horizontal plane. Both the first pressure cylinder body 14 and the second pressure cylinder body 16 are provided with energy conversion media. The energy conversion media are connected to the generator and are used to drive the generator to generate electricity. This invention discloses a wave energy power generation device. During operation, a float 12 floats on the sea surface. With the impact and swaying of the waves, the float 12 generates movement in four directions: swaying, pitching, heaving, and yawing. The movement of the float 12 drives the piston rods of each pressure cylinder to reciprocate, causing the energy conversion medium inside the pressure cylinder to enter the pressure circuit under pressure, driving the motor to rotate. The motor drives the generator to cut magnetic field lines to generate electricity, thereby converting wave energy into electrical energy.

[0019] When the wave energy generation device of this invention is working, the float 12 floats on the sea surface and sways with the impact of the waves. The largest component of the energy generated by the waves is in the vertical direction. This component causes the float 12 to sway. The swaying of the float 12 causes the piston rod 15 of the first pressure cylinder to reciprocate within the cylinder body 14 of the first pressure cylinder, thus converting wave energy into electrical energy. Specifically, when the force of the waves on the float 12 causes the float 12 to generate a rotational torque, the float 12 produces a yaw motion, thereby causing relative rotation between the cylinder body 16 of the second pressure cylinder and the float 12. At the same time, it also causes the central shaft connecting body 13 and each of the second pressure cylinders to rotate. The piston rods 17 of the pressure cylinders rotate relative to each other, which causes the float 12 and the central shaft connector 13 to rotate relative to each other. This causes the piston rods 17 of the second pressure cylinders to reciprocate within the cylinder body 16 of the second pressure cylinder, converting wave energy into electrical energy. When the force of the waves on the float 12 causes the float 12 to sway or undulate, the cylinder body 16 of the second pressure cylinder and the float 12 rotate relative to each other. At the same time, the central shaft connector 13 and each piston rod 17 of the second pressure cylinders rotate relative to each other, causing the piston rods 17 of the second pressure cylinders to reciprocate within the cylinder body 16 of the second pressure cylinder, converting wave energy into electrical energy. This invention discloses a wave energy generation device, comprising a fixed platform 11, a float 12, a central shaft connector 13, one or more sets of first energy conversion elements, and two or more sets of second energy conversion elements. The second energy conversion elements include a second pressure cylinder body 16 and a second pressure cylinder piston rod 17. The closed end of the second pressure cylinder body 16 is connected to the inner wall of the float 12. One end of the second pressure cylinder piston rod 17 is disposed inside the second pressure cylinder body 16, and the other end is connected to the central shaft connector 13. The second pressure cylinder body 16 is adapted to rotate relative to the float 12 in a horizontal plane. The piston rod 17 is adapted to rotate in the horizontal plane relative to the central axis connector 13, ensuring that the energy generated by the waves in multiple directions can cause the float 12 and the central axis connector 13 to move relative to each other, or cause the central axis connector 13 and the float 12 to move relative to each other, thereby converting wave energy into electrical energy and greatly improving the utilization rate of wave energy. At the same time, since the fixed platform 11 is fixed to the seabed or suspended at a certain distance from the sea surface, the wave energy power generation device of the present invention is not only suitable for shallow water areas but also for deep water areas, with better adaptability to different sea conditions and a simple structure.
