[0002] Wave energy is a abundant, renewable, and clean energy source. Currently, common wave energy power generation devices mainly include two types: oscillating float type and pendulum type. The oscillating float type power generation device drives a linear generator to generate electricity by moving a float up and down with the waves, and is sensitive to vertical wave motion; the pendulum type power generation device drives a rotary generator to generate electricity by swinging a pendulum plate under the action of waves, and makes full use of the lateral wave force.

[0003] However, single-form wave energy generation devices can often only effectively capture wave energy in one direction, resulting in limited energy conversion efficiency and unstable performance under different wave conditions. Furthermore, while some existing devices can combine oscillation power generation and pendulum power generation, these devices have complex structures, poor and cumbersome energy transfer paths, high energy conversion losses, and low power generation efficiency. Summary of the Invention

[0018] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0019] The following is for reference. Figures 1-4 A description of an oscillating float-type and pendulum-type combined wave energy generation device 1000 according to an embodiment of the present invention.

[0020] like Figures 1-4As shown, the oscillating float and pendulum composite wave energy generation device 1000 according to an embodiment of the present invention includes: a shell 100, a pendulum power generation component 10, and an oscillating float power generation component 20. The pendulum power generation component 10 includes a pendulum plate 11 and a pendulum power generation element 12. The pendulum plate 11 is rotatably disposed between opposite side walls of the shell 100. The moving part of the pendulum power generation element 12 is connected to the end of the pendulum plate 11. The oscillating float power generation component 20 includes a support plate 21 and a linear power generation element 22. The support plate 21 is movably disposed between opposite side walls of the shell 100. The support plate 21 is spaced above the pendulum power generation component 10. The linear power generation element 22 is disposed on the upper side of the support plate 21. The moving part of the linear power generation element 22 is connected to the support plate 21.

[0021] Specifically, by rotatably setting the pendulum plate 11 between the opposite side walls of the outer casing 100, the waves on the sea can drive the pendulum plate 11 to rotate in the front-back direction. The rotation of the pendulum plate 11 in the front-back direction can drive the mover of the pendulum power generation component 12 connected to it to rotate, thereby enabling the pendulum power generation component 10 to generate electricity. In this way, the energy generated by the waves on the sea in the lateral direction can be fully utilized and converted into electrical energy.

[0022] Furthermore, the load-bearing plate 21 is movably disposed between the opposite side walls of the outer shell 100. The waves on the sea can drive the load-bearing plate 21 to move in the vertical direction. The vertical movement of the load-bearing plate 21 can drive the mover of the linear generator 22 connected to it to move up and down, thereby enabling the linear generator 22 to generate electricity. In this way, the energy generated by the waves on the sea in the vertical direction can be fully utilized and converted into electrical energy.

[0023] In some embodiments of the present invention, the vertical direction is the up-down direction, and the horizontal direction is the front-back direction. It should be noted that when the pendulum plate 11 of the pendulum power generation component 10 is rotatably connected between the two side walls in the front-back direction of the outer casing 100, the horizontal direction can also be the left-right direction.

[0024] Furthermore, since the support plate 21 is spaced above the pendulum power generation component 10 and the linear power generation component 22 is located on the upper side of the support plate 21, there will be no mutual interference between the oscillating float power generation component 20 and the pendulum power generation component 10. This can improve the structural reliability of the oscillating float and pendulum composite wave energy power generation device 1000, thereby ensuring the power generation efficiency of the oscillating float and pendulum composite wave energy power generation device 1000.

[0025] Therefore, by integrating the pendulum-type power generation component 10 and the oscillating float-type power generation component 20 on the outer shell 100, it is possible to achieve efficient capture and combined power generation of both the lateral and vertical forces of waves, thereby improving the overall conversion efficiency of wave energy and the environmental adaptability of the device. Moreover, the structure is simple and the energy conversion loss is small.

[0026] Combination Figure 1 and Figure 2 As shown, there are two pendulum generators 12, which are respectively disposed on opposite side walls of the outer casing 100, and the movers of the two pendulum generators 12 are respectively connected to the two ends of the pendulum plate 11.

[0027] Specifically, by setting two pendulum generators 12 and placing them on opposite side walls of the outer casing 100, with the movers of the two pendulum generators 12 connected to the two ends of the pendulum plate 11, the energy generated by the rotation of the pendulum plate 11 can be fully utilized, thereby improving the power generation efficiency of the pendulum generators 12 per unit time.

[0028] Combination Figure 1 and Figure 2 As shown, the swing plate 11 includes a rotating shaft 112 and a swing plate body 111. The rotating shaft 112 is rotatably connected between the two opposite side walls of the outer casing 100. The swing plate 11 is connected to the rotating shaft 112. Two swing-type power generation elements 12 are disposed at both ends of the rotating shaft 112. The movers of the two swing-type power generation elements 12 are respectively connected to both ends of the rotating shaft 112.

[0029] Specifically, by rotatably connecting the rotating shaft 112 between the two opposing side walls of the outer casing 100, and connecting the pendulum plate 11 to the rotating shaft 112, two pendulum power generation components 12 are disposed at both ends of the rotating shaft 112, and the movers of the two pendulum power generation components 12 are respectively connected to both ends of the rotating shaft 112, the structure of the pendulum power generation assembly 10 can be simplified while ensuring stable power generation of the pendulum power generation components 12, thereby shortening the energy transfer path and improving the energy conversion efficiency.

[0030] Combination Figure 3 As shown, the pendulum generator 12 includes a first housing, a first mover 122 and a first stator 123. The first stator 123 and the first mover 122 are disposed inside the first housing. The first stator 123 is circumferentially disposed around the outside of the first mover 122. The first mover 122 is rotatable relative to the first stator 123 and is connected to the rotating shaft 112.

[0031] Specifically, by placing the first stator 123 and the first mover 122 inside the first housing, and circumferentially surrounding the first mover 122, the first mover 122 can rotate circumferentially relative to the first stator 123 as the shaft 112 rotates, thereby cutting magnetic field lines to generate alternating current and complete power generation.

[0032] Combination Figure 1 and Figure 2As shown, the oscillating float and pendulum composite wave energy power generation device 1000 also includes a force transmission plate 30, which is movably disposed on at least one of the two side walls of the outer shell 100. The upper and lower ends of the force transmission plate 30 are connected to the load-bearing plate 21 and the pendulum plate 11, respectively.

[0033] Specifically, by providing a force transmission plate 30 on at least one of the opposite side walls of the outer shell 100, the force transmission plate 30 can be moved in the vertical direction. When the waves at the crest excite the pendulum plate 11 to rotate, they also generate an upward wave force on the pendulum plate 11. Since the force transmission plate 30 is connected to the pendulum plate 11, the pendulum plate 11 can drive the force transmission plate 30 to move upward together. Since the support plate 21 is connected to the force transmission plate 30, the force transmission plate 30 will drive the support plate 21 to move upward together. This causes the mover of the linear power generation component 22 connected to the force transmission plate 30 to move relative to the rotor, thereby generating electricity. This can further improve the power generation efficiency of the oscillating float-type and pendulum-type composite wave energy power generation device 1000.

[0034] Combination Figure 4 As shown, the linear generator 22 includes a second housing 221, a second mover 222, and a second stator 223. The second mover 222 and the second stator 223 are both disposed inside the second housing 221. The second stator 223 is circumferentially disposed around the outside of the second mover 222. The second mover 222 can move up and down relative to the second stator 223 and is connected to the load-bearing plate 21.

[0035] Specifically, by placing both the second mover 222 and the second stator 223 inside the second housing 221, with the second stator 223 circumferentially surrounding the outside of the second mover 222, and allowing the second mover 222 to move up and down relative to the second stator 223 and connect to the load-bearing plate 21, the structure of the linear generator 22 can be simplified, thereby improving the power generation efficiency of the linear generator 22.

[0036] Combination Figure 4 As shown, an elastic element 23 is also provided inside the second housing 221, and the elastic element 23 is connected between the second mover 222 and the second housing 221.

[0037] Specifically, by connecting the elastic element 23 between the second mover 222 and the second housing 221, the elastic element 23 can not only assist the second mover 222 in resetting and improve the power generation effect of the linear generator 22, but also, when the energy of the waves at sea is large, the load-bearing plate 21 will drive the second mover 222 to move quickly. In this case, the second mover 222 is prone to a strong impact with the second housing 221. By connecting the elastic element 23 between the second mover 222 and the second housing 221, the elastic element 23 can buffer the movement of the second mover 222 and prevent the second mover 222 from having a strong impact with the second housing 221, which would cause structural damage.

[0038] In some embodiments of the present invention, guide rods extending vertically are provided on both sides of the load-bearing plate 21, and guide grooves extending vertically are provided on the opposite side walls of the outer casing 100, with the guide rods and guide grooves guiding and cooperating in the vertical direction.

[0039] Specifically, by providing guide rods extending vertically on both sides of the load-bearing plate 21 and providing guide grooves extending vertically on the opposite side walls of the outer casing 100, the guide rods and guide grooves can be guided and matched in the vertical direction, thereby improving the smoothness and stability of the load-bearing plate 21 in the vertical direction.

[0040] In some embodiments of the present invention, the oscillating float-type and pendulum-type composite wave energy generation device 1000 further includes a controller, which is electrically connected to the linear generator 22 and the pendulum generator 12, respectively.

[0041] Specifically, the linear generator 22 can also perform active damping control functions. The oscillating float and pendulum composite wave energy generator 1000 also includes a speed sensor, a current sensor, and a power regulation device. The power regulation device includes, but is not limited to, a rectifier, a DC-DC converter, a power switch, and a braking resistor. The electrical energy generated by the linear generator 22 is converted by the rectifier and the DC-DC converter to charge the battery or be output to the outside, thus achieving stable and efficient power generation.

[0042] When the wave energy is too large and the amplitude of the oscillating float-type and pendulum-type composite wave energy generator 1000 exceeds the limit, the controller controls the power switch to switch to the braking resistor, so that the linear generator 22 works in electromagnetic braking mode, generating a damping force opposite to the direction of motion, effectively limiting the amplitude of the load-bearing plate 21 and the pendulum plate 11, protecting the mechanical structure from overload damage. This can further improve the structural reliability of the oscillating float-type and pendulum-type composite wave energy generator 1000.

[0043] Combination Figure 1 and Figure 2As shown, a plurality of fixing posts 40 are provided on the lower side of the outer casing 100, and the plurality of fixing posts 40 are arranged circumferentially on the lower side of the outer casing 100.

[0044] Specifically, by providing multiple fixing piles 40 on the lower side of the outer shell 100 and circumferentially spacing the multiple fixing piles 40 on the lower side of the outer shell 100, the oscillating float-type and pendulum-type composite wave energy power generation device 1000 can be connected to the seabed through the multiple fixing piles 40 to realize the installation and application of the oscillating float-type and pendulum-type composite wave energy power generation device 1000 at sea, which can improve the stability of the installation and application of the oscillating float-type and pendulum-type composite wave energy power generation device 1000 at sea.
