[0002] Wave energy is a clean and renewable resource, and its development and utilization can mitigate the environmental damage caused by burning fossil fuels. Wave energy resources are abundant and have broad prospects for development and utilization.

[0009] Preferably, the outer periphery of the power generation unit support frame is provided with a first steel cable fixing anchor point.

[0010] The present invention also provides a wave power generation module, comprising a plurality of wave power generation devices as described above, wherein adjacent wave power generation devices are connected by steel cable clamps to a first steel cable fixing anchor point.

[0011] The present invention also provides a wave power generation system, including a fixed frame and a fixed bracket, and further including a wave power generation module as described above, wherein the fixed bracket supports the fixed frame of the linear generator.

[0012] Preferably, the fixed frame is provided with a second steel cable fixing anchor point, and the wave power generation module is connected to the second steel cable fixing anchor point through a steel cable.

[0013] Compared to the aforementioned background technology, the present invention provides a wave power generation device, comprising a power generation unit support frame, a swing generator, a floating power generation component, a float box assembly, a linear generator, and a linear generator fixing frame. The power generation unit support frame provides support and is equipped with a floating component fixing bearing seat. The swing generator is rotatably mounted on the power generation unit support frame. The floating power generation component is connected to the swing generator and the floating component fixing bearing seat, and is rotatable relative to the power generation unit support frame. The floating power generation component includes a photovoltaic panel and a floating plate, the floating plate being used to mount the photovoltaic panel and enabling the photovoltaic panel to float on the water surface. The float box assembly is located on the side away from the photovoltaic panel and includes a float box plate and a support frame for placing the float box plate.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the position 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 of this invention.

[0030] Please see Figures 1 to 2This embodiment provides a wave power generation device, including: a power generation unit support frame 100 with a floating component fixed bearing seat 110, a rotatable swing generator 120 on the power generation unit support frame 100, a floating power generation component 200 installed between the floating component fixed bearing seat 110 and the swing generator 120, the floating power generation component 200 being rotatable relative to the power generation unit support frame 100, the floating power generation component 200 including a photovoltaic panel 210 and a floating plate 220, the floating plate 220 being used to install the photovoltaic panel 210 and enabling the photovoltaic panel 210 to float on the water surface;

[0031] A floating box assembly 300 is provided on the side away from the photovoltaic panel 210. The floating box assembly 300 includes a floating box plate 310 and a support frame 320 for placing the floating box plate 310. The support frame 320 is connected to the power generation unit support frame 100. There is space between the floating box plate 310 and the floating plate 220 for the floating power generation assembly 200 to rotate. The linear generator 400 is connected to the power generation unit support frame 100 through a connecting rod 500. The connecting rod 500 is located on the side away from the photovoltaic panel 210 and is perpendicular to the floating box plate 310. The linear generator fixing frame 600 is provided with a linear generator fixing base 610, which is connected to the linear generator 400.

[0032] It is understood that the floating power generation component 200 is fixed to the power generation unit support frame 100 by the floating component fixed bearing seat 110 and the swing generator 120. The number of floating component fixed bearing seats 110 and swing generators 120 corresponds one-to-one with the number of floating power generation components 200.

[0033] In this invention, the floating plate 220 is made of non-metallic materials such as nylon and ABS plastic. Its internal hollow structure reduces its density to less than water and increases structural strength. The photovoltaic panel 210 is fixed to the floating plate 220, allowing the photovoltaic panel 210 to float on the water surface. The photovoltaic panel 210 undergoes enhanced sealing and insulation treatment, making it resistant to seawater corrosion and providing reliable insulation in seawater. It also undergoes special treatment to resist the attachment of aquatic organisms. The photovoltaic panel 210 is cooled by seawater, increasing its power generation per unit area and improving power density. Furthermore, to enhance the power generation and efficiency of the wave power generation device, a support frame 320 and a floating box plate 310 are arranged on the side of the floating power generation component 200 away from the photovoltaic panel 210. The floating box plate 310 can be made of non-metallic materials or hollow metallic materials. The floating box plate 310 possesses a certain mechanical strength and is resistant to seawater corrosion and the attachment of aquatic organisms.

[0034] Specifically, the photovoltaic panels 210 in the floating power generation component 200, which floats on the water surface, generate electricity under sunlight. At the same time, the floating power generation component 200 is buoyed by the waves. Under the action of the buoyancy of the waves and the gravity of the wave power generation device, the floating power generation component 200 swings back and forth and the wave power generation device moves up and down. The pontoon, under the action of seawater buoyancy, wave force and its own gravity, also moves up and down, in the same way as the floating power generation component 200. The back-and-forth swing of the floating power generation component 200 can drive the swing generator 120 to generate electricity. The up and down movement of the wave power generation device drives the linear generator 400 to reciprocate through the connecting rod 500, thereby generating electricity. With this configuration, the wave power generation device can generate photovoltaic power using solar radiation, and at the same time, it can also use the waves to drive the swing generator 120 and the linear generator 400 to generate electricity, which can improve the energy utilization efficiency of the wave power generation device on the water surface.

[0035] It should be noted that the wave power generation device can also be arranged in a rectangular, circular, or polygonal form, etc., and no specific limitation is made here.

[0036] Understandably, the buoyancy of the waves drives the oscillating generator 120 to generate electricity. Simultaneously, the oscillating generator 120 is equipped with an oscillation angle measuring device and an oscillation angle limiting device. When the oscillation angle exceeds a set value, it can be limited or locked by the oscillation angle limiting device. Furthermore, the wave power generation device has a priority control principle for power generation. For example, when there is ample sunlight and the waves are small, because photovoltaic power generation capacity is greatly affected by the angle of sunlight, priority can be given to ensuring photovoltaic power generation while limiting the oscillation angle.

[0037] Furthermore, the linear generator 400 is internally equipped with springs. Under the influence of buoyancy, the wave generator drives the reciprocating rod of the linear generator 400 upwards, compressing the springs. The spring force and the gravity of the wave generator accelerate the return of the reciprocating rod to its original position. The internal springs of the linear generator 400 can be replaced with air springs or hydraulic springs. The linear generator 400 is internally equipped with a displacement sensor and a reciprocating rod locking mechanism. When the waves are large enough to cause the reciprocating rod displacement to exceed a set value, the reciprocating rod can be locked to prevent damage to the linear generator 400.

[0038] It should be noted that, depending on the actual needs of different application scenarios, the linear power generation section or the swing power generation section can be omitted, and only the swing power generation method or the linear power generation method can be combined with photovoltaic power generation.

[0039] Preferably, the power generation unit support frame 100 is provided with a spherical bearing base 130, and the connecting rod 500 is provided with spherical bearings 510 at both ends, and the connecting rod 500 is connected to the power generation unit support frame 100 by bearings.

[0040] It is understandable that the power generation unit support frame 100 is provided with a spherical bearing base 130, and the connecting rod 500 is provided with spherical bearings 510 at both ends. Through the cooperation of the spherical bearing base 130 and the spherical bearings 510, the connecting rod 500 and the power generation unit support frame 100 are connected by bearings.

[0041] It should be noted that there are many ways to connect, and no specific limitation is made here, as long as the above purpose can be achieved.

[0042] Preferably, a first waterproof sleeve 520 is provided on the outside of the spherical bearings 510 located at both ends of the connecting rod 500. The first waterproof sleeve 520 is used to prevent liquid from entering the spherical bearings 510.

[0043] Understandably, the presence of a first waterproof sleeve 520 on the outside of the spherical plain bearing 510 can prevent liquid from entering the spherical plain bearing 510, thereby increasing the service life of the spherical plain bearing 510.

[0044] Preferably, the linear generator fixing frame 600 and the connecting rod 500 are respectively connected to the linear generator 400 by bearings. The linear generator 400 is provided with a second waterproof sleeve 410 at both ends to prevent liquid from entering the interior of the linear generator 400.

[0045] In this invention, the translational movement of the wave power generation device is absorbed by the connecting rod 500, the spherical bearing 510, and the steel cable, thus preventing damage to the linear generator 400. The vertical displacement of the wave power generation device is driven by the connecting rod 500 and the spherical bearing 510 to drive the reciprocating rod of the linear generator 400 to reciprocate, thereby generating electricity.

[0046] It is understandable that when liquids such as water enter the linear generator 400, it will affect the normal operation of the linear generator 400. At this time, a second waterproof sleeve 410 is provided at both ends of the linear generator 400, which can effectively prevent the influence of liquids such as water on the linear generator 400, thereby improving the power generation efficiency of the linear generator 400.

[0047] Preferably, the power generation unit support frame 100 is provided with a first steel cable fixing anchor point 140 on its outer periphery.

[0048] It is understandable that when the power generation unit support frame 100 is provided with a first steel cable fixing anchor point 140 on its outer periphery, different wave power generation devices can be connected through the first steel cable fixing anchor point 140. Alternatively, the wave power generation device can be fixed to other devices through the first steel cable fixing anchor point 140 on the outer periphery of the power generation unit support frame 100 to generate electricity as needed.

[0049] In addition, a wave power generation module includes several wave power generation devices, and adjacent wave power generation devices are connected by steel cable clamps to the first steel cable fixing anchor point 140.

[0050] It should be noted that the power generation unit support frame 100 is equipped with first steel cable fixing anchor points 140 around its perimeter. The number of first steel cable fixing anchor points 140 is reasonably arranged according to the size of the power generation device. The power generation unit support frames 100 of adjacent wave power generation devices can be interconnected with each other as a whole through the first steel cable fixing anchor points 140 and steel cables. The connection method here is a flexible connection, which can allow for a certain degree of displacement.

[0051] In addition, a wave power generation system includes a fixed frame 700 and a fixed bracket 800, and also includes a wave power generation module. The fixed bracket 800 supports the fixed frame 600 of the linear generator.

[0052] Please see Figure 3 The linear generator mounting frames 600 are connected to the bottom of the mounting frame 700 via several mounting brackets 800, forming a rigid connection. This together completes the connection and fixation of each wave power generation device, thus completing the integrated installation of the wave power generation system.

[0053] It should be noted that the wave power generation system can be arranged in rectangular, circular, polygonal, or other shapes, depending on the applicable location.

[0054] Preferably, the fixed frame is provided with a second steel cable fixing anchor point 710, and the wave power generation module is connected to the second steel cable fixing anchor point 710 through a steel cable.

[0055] The power generation unit support frames 100 of adjacent wave power generation devices can be connected to each other as a whole by the first steel cable fixing anchor point 140 and then connected to the fixed frame 700 by the second steel cable fixing anchor point 710, thus completing the installation of the wave power generation module. The connection method here is a flexible connection, which can cause a certain degree of displacement.

[0056] Once installed, the wave power generation system is anchored to the seabed, lakebed, or riverbed. It can also be integrated with offshore wind power systems, with the power generation unit fixed to the base of the wind turbine.

[0057] Furthermore, it should be noted that the power generation unit support frame 100, the linear generator fixing frame 600, the fixing frame 700, and the fixing bracket 800 in this invention are equipped with cable fixing devices for arranging power cables.

[0058] In summary, this embodiment provides a wave power generation device, comprising: a power generation unit support frame 100 with a floating component fixed bearing seat 110; a rotatable swing generator 120 mounted on the power generation unit support frame 100; a floating power generation component 200 installed between the floating component fixed bearing seat 110 and the swing generator 120; the floating power generation component 200 being rotatable relative to the power generation unit support frame 100; the floating power generation component 200 including a photovoltaic panel 210 and a floating plate 220; the floating plate 220 for mounting the photovoltaic panel 210 and enabling the photovoltaic panel 210 to float on the water surface; and a buoyancy box provided on the side opposite to the photovoltaic panel 210. The component 300 includes a floating box assembly 300, which includes a floating box plate 310 and a support frame 320 for placing the floating box plate 310. The support frame 320 is connected to the power generation unit support frame 100. There is space between the floating box plate 310 and the floating plate 220 for the floating power generation assembly 200 to rotate. The linear generator 400 is connected to the power generation unit support frame 100 via a connecting rod 500. The connecting rod 500 is located on the side away from the photovoltaic panel 210 and is perpendicular to the floating box plate 310. The linear generator fixing frame 600 is provided with a linear generator fixing base 610, which is connected to the linear generator 400.

[0059] Specifically, the photovoltaic panel 210 in the floating power generation component 200, which floats on the water surface, generates electricity under sunlight. At the same time, the floating power generation component 200 is buoyed by the waves. Under the action of the buoyancy of the waves and the gravity of the wave power generation device, the floating power generation component 200 swings back and forth, and the wave power generation device moves horizontally and vertically. The pontoon, under the action of seawater buoyancy, wave force, and its own gravity, also moves vertically, in the same direction as the floating power generation component 200. The back-and-forth swing of the floating power generation component 200 can drive the swing generator 120 to generate electricity. The horizontal movement of the wave power generation device is absorbed by the connecting rod 500, the joint bearing 510, and the steel cable to avoid damage to the linear generator 400. The vertical movement of the wave power generation device drives the reciprocating rod of the linear generator 400 to move back and forth through the connecting rod 500 and the joint bearing 510, thereby generating electricity. With this configuration, the wave power generation device can generate photovoltaic power using sunlight and also generate electricity using waves to drive the swing generator 120 and the linear generator 400, which can improve the comprehensive energy utilization effect of the wave power generation device on the water surface.
