Description

Technical Field

[0001] The invention relates to the field of renewable energy technology and offshore power generation technology, and in particular to a floating photovoltaic wave energy power generation platform with a wave-breaking device. Background Art

[0002] The development and utilization of renewable energy technologies has become one of the research focuses of various countries. Among the many renewable energy technologies, offshore photovoltaic power generation and wave power generation technologies have developed rapidly and have broad application prospects.

[0003] Compared with land-based photovoltaics, floating photovoltaics have the advantages of saving land resources, larger available space, more sunlight, and easy large-scale modularization. There are many types of floating platforms that carry photovoltaic panels, among which the structure of a combination of buoys and brackets has the strongest ability to resist wind and waves. Wave energy devices have the characteristics of high energy density, stable energy supply, simple structure and not easy to damage. They convert the energy captured from waves into mechanical energy and other transmission system energy through the power output system, and then further convert it into electrical energy for output.

[0004] In order to improve energy utilization and space utilization, multi-energy complementarity of offshore clean energy is an important development direction. When developing offshore renewable energy power generation equipment, facing the harsh and changeable marine environment, especially the impact of waves, improving the structure's ability to resist wind and waves and ensuring the safety of the equipment are the primary tasks, which are also the guarantee for saving costs and improving efficiency.

[0005] At present, in order to avoid damage to solar power generation devices (specifically photovoltaic panels) caused by upwelling (i.e. waves formed by rushing water), the floating platform carrying the photovoltaic panels has high requirements for motion response, and its structure usually has weak wind and wave resistance, which is not conducive to safe and stable power generation.

[0006] Therefore, there is an urgent need to develop a technology that can solve the above technical problems. Summary of the invention

[0007] The purpose of the present invention is to provide a floating photovoltaic wave energy power generation platform with a wave-breaking device in view of the technical defects in the prior art.

[0008] To this end, the present invention provides a floating photovoltaic wave energy power generation platform with a wave-breaking device, which includes a main platform, a wave-breaking device and a wave energy device, and an adaptive mooring system;

[0009] On the top of the main platform, there is a photovoltaic panel power generation device for solar power generation;

[0010] Wave-absorbing devices are arranged at intervals around the outer side of the main platform;

[0011] The wave-breaking device and the main platform are flexibly connected via multiple connecting cables;

[0012] Wave-breaking device, used to reduce the wave impact on the main platform, reduce wave load and improve the stability of the main platform;

[0013] A plurality of wave energy devices are arranged in the wave-breaking device;

[0014] The wave-breaking device is used to reciprocate under the action of waves and drive the wave energy device to move relative to each other;

[0015] The wave energy device is used to convert mechanical energy into electrical energy in real time and output it when relative motion occurs;

[0016] The main platform and the wave-breaking device are connected to the adaptive mooring system respectively;

[0017] Adaptive mooring system, used to enhance the wind and wave resistance of the main platform and wave-breaking device and maintain the stability of the main platform and wave-breaking device;

[0018] The main platform includes: a hollow main platform storage cabin platform;

[0019] The main platform storage cabin platform is equipped with a main platform winch, a main platform winch controller and a connecting cable;

[0020] There are multiple turns of connecting cable wound on the main platform winch;

[0021] The main platform winch controller is connected to the outwardly extending end of the connecting cable and is used to control the movement constraint of the connecting cable or release the movement constraint of the connecting cable.

[0022] It can be seen from the technical solution provided by the present invention that, compared with the prior art, the present invention provides a floating photovoltaic wave energy power generation platform with a wave-breaking device, which is scientifically designed and integrates photovoltaic power generation and wave energy power generation, and can improve safety through the wave-breaking device. The present invention can better resist external environmental loads while improving power generation efficiency, and has great practical significance.

[0023] By applying the present invention, the effect of traditional breakwaters can be optimized. On the one hand, by utilizing the radiation wave generation and wave superposition principles and using wave absorbing devices, the impact of wave impact on the main platform can be effectively reduced. In addition, wave energy devices are installed to further increase additional damping and fully utilize energy. On the other hand, since it is difficult to provide sufficient restoring stiffness using catenary mooring, it is impossible to effectively reduce the heave and swaying motion of the platform. Although the use of tensioned mooring can effectively suppress the motion, it cannot overcome the tidal range problem and is more prone to mooring fatigue damage. To this end, the present invention combines a new wave absorbing device with a floating photovoltaic power generation platform, which can greatly reduce the effect of wave loads and reduce the risk of damage to the power generation device.

[0024] For the present invention, the tensioned mooring is activated only in dangerous sea conditions and is retracted in normal sea conditions, thereby facilitating adaptation to the influence of different marine environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] It should be noted that the floating tube 103 is a slender tubular structure that provides structural strength in addition to the support column 102. Multiple floating tubes 103 are crisscrossed inside the main platform 1 and are welded to the support column 102, the buoy 101 and the main platform storage compartment 105 respectively.

[0061] In specific implementation, the main platform storage cabin platform 105 includes a plurality of compartment platforms 1050 distributed around;

[0062] The outer side of the bottom of each compartment platform 1050 is provided with a reduction plate 104 extending outward;

[0063] The reduction plate 104 is a rectangular cross-section plate;

[0064] It should be noted that the reduction plate 104 can provide additional damping to suppress the movement of the main platform 1 .

[0065] In a specific implementation, the diameter of the support column 102 is larger than the diameter of the floating tube 103 .

[0066] It should be noted that the six support columns 102 are circumferentially distributed at equal intervals on the six corners of the main platform 1 to play a role in structural reinforcement and support. Therefore, the diameter of the support column 102 is larger than the diameter of the floating tube 103.

[0067] It should be noted that the buoys 101 are mainly used to provide buoyancy and are rigidly connected to the upper surface of the main platform storage compartment platform 105 at equidistant intervals in annular direction. The upper surface of the buoys 101 is rigidly connected to the floating tubes 103 .

[0069] In the present invention, it should be noted that Figure 3 , 4As shown, the wave-breaking device 2 is arranged around the outer side of the main platform 1 and is spaced a certain distance from the main platform 1. On the one hand, it is used to shield the wind and wave flow for the main platform 1, and on the other hand, it is used to generate radiation waves, which can effectively reduce the impact of wave loads under the interaction of waves.

[0070] In the present invention, in a specific implementation, the wave absorbing device 2 includes a plurality of segmented parts 200 (e.g., eight segmented parts, which are in the shape of circular arcs) of equal length, distributed around and connected in sequence;

[0074] Inside the wave-breaking device storage cabin 204, an adaptive mooring system 5 is arranged;

[0075] An adaptive mooring system 5, comprising a wave-breaking device winch 502 and a wave-breaking device winch controller 506, and an adaptive mooring line 501;

[0076] A plurality of turns of adaptive mooring cable 501 are wound around the winch 502 of the wave-breaking device;

[0077] The wave-breaking device winch controller 506 is connected to the outwardly extending end of the adaptive mooring cable 501 (i.e., the end away from the wave-breaking device winch 502), and is used to control the movement constraint of the adaptive mooring cable 501, or release the movement constraint of the adaptive mooring cable 501;

[0078] Below the wave-breaking device storage cabin 204, an inclined, hollow anchoring channel 205 is provided;

[0079] The outwardly extending end of the adaptive mooring line 501 passes through the anchoring channel 205 and is connected to an anchor 503;

[0080] The anchor 503 is also connected to the outwardly extending end of the connecting cable 207 in the main platform 1.

[0081] It should be noted that, in order to facilitate the installation, disassembly and arrangement of equipment, the wave-breaking device 2 can be divided into eight segments 200 at equal intervals, and each segment 200 is arranged with a wave energy device 3, a wave height monitor 201, a fixed ballast tank 202, a variable ballast tank 203, an adaptive mooring storage tank 204, an anchoring channel 205, and a sunken anchor 503.

[0082] Further, the anchor 503 is located in the inner direction of the wave absorbing device 2;

[0083] The upper end of the anchoring channel 205 is open and communicated with the bottom of the wave-breaking device storage cabin 204;

[0084] The lower end of the anchor channel 205 is open and is arranged on the inner wall of the wave absorbing device 2;

[0085] Furthermore, an anchor stopper 504 is provided on the lower opening of the anchoring channel 205 .

[0086] It should be noted that the upper opening of the anchoring channel 205 is connected to the wave-breaking device storage compartment 204, and the lower opening of the anchoring channel 205 is opened on the inner wall of the wave-breaking device 2. The anchoring channel 205 is used to provide a channel for the adaptive mooring cable 501 to move.

[0087] The anchor stopper 504 is located at the lower opening of the anchoring channel 205, and is used to further fix the position of the anchor 503 to prevent the anchor 503 from accidentally falling;

[0088] The anchor 503 is located below the anchor stopper 504, connected to the segmented part 200 in the wave-breaking device 2 through the adaptive mooring cable 501, and connected to the main platform 1 through the connecting cable 207. The connection points are all constrained to move in translation in three degrees of freedom and release three degrees of freedom to rotate.

[0089] It should be noted that the wave-breaking device winch controller 506 and the main platform winch controller 107 are paired with the corresponding wave-breaking device winch 502 and the main platform winch 106, respectively. When the wave-breaking device winch controller 506 and the main platform winch controller 107 are turned on, the movement constraints of the adaptive mooring cable 501 and the connecting cable 207 are released respectively. The effective parts of the adaptive mooring cable 501 and the connecting cable 207 can be extended or shortened by controlling the wave-breaking device winch 502 and the main platform winch 106.

[0090] In specific implementation, a fixed ballast tank 202 is provided at the inner bottom of each segmented part 200;

[0091] Directly above the fixed ballast tank 202, a variable ballast tank 203 is provided;

[0092] It should be noted that the fixed ballast tank 202 is located at the inner bottom of the wave-breaking device 2 and serves to increase the counterweight so as to balance the gravity buoyancy of the wave-breaking device 2 in still water;

[0093] In specific implementation, a one-way water inlet gate 208 and a one-way water outlet gate 209 are provided on the outer side wall of the variable ballast tank 203;

[0094] The variable ballast tank 203 is used to store ballast water;

[0095] The one-way water inlet gate 208 and the one-way water outlet gate 209 are both located on the outer side wall of the wave absorbing device 2;

[0096] A one-way water inlet gate 208, located above the one-way water outlet gate 209;

[0097] It should be noted that the variable ballast tank 203 is arranged above the fixed ballast tank 202, consists of a plurality of compartments, has no contents initially, and can adjust the weight of ballast water according to different working conditions and whether the adaptive mooring system 5 is enabled. The hatch of the variable ballast tank 203 is opened on the outer wall of the wave-breaking device 2, and is equipped with a one-way water inlet gate 208 and a one-way water outlet gate 209; wherein, the one-way water inlet gate 208 is located above the one-way water outlet gate 209, so that the pressure of the water inlet gate can be greater than that of the water outlet gate, which is more convenient for water intake and discharge.

[0098] In specific implementation, the wave height monitor 201 is installed on the outer wall of the wave-breaking device 2, and the installation height is level with the average water surface.

[0099] In specific implementation, the wave energy device 3 is installed inside the wave absorbing device 2;

[0100] The installation height of the wave energy device 3 is level with the wave height monitor 201 and is located below the wave-breaking device storage compartment 204 and above the variable ballast compartment 203;

[0101] It should be noted that, when in use, the wave absorbing device 2 reciprocates (including up and down movement, front and back movement, and left and right movement) under the action of waves, thereby driving the wave energy device 3 to move relative to each other, and finally converting the mechanical energy into electrical energy through the multi-stage transmission system built into the wave energy device 3. For the present invention, by capturing, converting and utilizing the wave energy of the wave energy device 3, the damping of the floating body movement is increased, the wave energy is dissipated, and the wave absorbing and protection effects of the wave absorbing device 3 are further optimized. At the same time, the operation of the wave absorbing device 3 is also provided with electricity.

[0102] In the present invention, in specific implementation, the floating photovoltaic wave energy power generation platform of the present invention further includes: a fixed mooring system 4;

[0103] A fixed mooring system 4, comprising a first fixed mooring line 401 and a second fixed mooring line 402;

[0104] One end of the first fixed mooring cable 401 and one end of the second fixed mooring cable 402 are connected to the outer walls of the main platform 1 and the outer walls of the wave-breaking device 2 respectively;

[0105] The other end of the first fixed mooring cable 401 and the other end of the second fixed mooring cable 402 are fixedly connected to the seabed respectively.

[0106] In specific implementation, the outer walls of the main platform 1 are respectively connected to a plurality of groups of first fixed mooring cables 401 distributed at equal intervals;

[0107] Each set of first fixed mooring cables 401 includes two mooring cables;

[0108] The outer walls of the wave-breaking device 2 are connected to a plurality of groups of second fixed mooring cables 402 distributed at equal intervals;

[0109] Each set of second fixed mooring lines 402 includes two mooring lines;

[0110] In specific implementation, the horizontal arrangement angle between each group of first fixed mooring cables 401 and the adjacent group of second fixed mooring cables 402 differs by 180 degrees, or the horizontal arrangement angle difference is an acute angle, so as to avoid collision or entanglement between the mooring cables.

[0111] It should be noted that the side wall of the main platform storage cabin platform 105 is provided with a through hole for passing the connecting cable 207 , and a mounting hole for docking the first fixed mooring cable 401 in the fixed mooring system 4 .

[0112] It should be noted that if Figure 3 As shown, the main platform 1 and the wave-breaking device 2 are respectively moored and positioned by mooring cables of an independent fixed mooring system 4. The first fixed mooring cable 401 on the main platform 1 and the second fixed mooring cable 402 on the wave-breaking device 2 are both arranged in 3×2, i.e., three groups, two mooring cables in each group, the horizontal angle between the two mooring cables in the group is 5 degrees, and the horizontal angle between the center lines of each group is 120 degrees. The first fixed mooring cable 401 and the second fixed mooring cable 402 respectively connect the main platform 1 and the wave-breaking device 2 to the seabed, and the connection points are constrained for three degrees of freedom translation and released for three degrees of freedom rotation.

[0113] It should be noted that, considering that offshore photovoltaics are usually arranged in shallow waters with large tidal ranges, the first fixed mooring cable 401 and the second fixed mooring cable 402 use steel catenary anchor chains, which mainly rely on the gravity of the mooring cable itself to provide restoring stiffness.

[0114] In order to more clearly understand the technical solution of the present invention, the specific functions of each functional component in the present invention are described below.

[0115] In the present invention, the main platform 1 is a floating body that carries the photovoltaic panel equipment, including a buoy 101, a main platform storage cabin platform 105, a support column 102, a floating tube 103 and a damping plate 104. The buoy 101 is used to provide buoyancy for the main platform 1 and is fixed on the support column 102. The support column 102 and the floating tube 103 are used to support the buoy 101 and the photovoltaic panel power generation equipment 6, and also provide a part of the buoyancy. The damping plate 104 is an extended structure arranged around the circumference of the main platform, which is used to increase the damping of the main platform to improve the motion performance.

[0116] The external structure of the main platform 1 is a regular hexagon in a top view, and the main platform storage cabin platform 105 is a regular hexagonal hollow annular cabin arranged at the bottom of the main platform 1.

[0117] The floating tube 103 has a smaller diameter to reduce the weight of the main platform, and the supporting column 102 has a larger diameter to ensure structural strength and to support the buoy 101. The reduction plates 104 are rectangular in cross section and are arranged at equal intervals around the outside of the bottom floating tube.

[0118] In the present invention, the wave-breaking device 2 is an annular structure arranged on the periphery of the main platform. The wave-breaking device 2 is a centrally symmetrical circular ring structure, and is positioned with the main platform 1 using independent moorings.

[0119] In the present invention, a fixed mooring system is used to prevent the floating photovoltaic wave energy power generation platform from undergoing a large displacement in the horizontal plane, including mooring on the main platform and mooring on the wave-breaking device, and the fixed mooring system is always enabled.

[0120] In the present invention, the adaptive mooring system 5 is activated only in severe sea conditions, and requires the coordinated use of a wave height monitor, a variable ballast tank, an adaptive mooring storage tank 204, an anchoring channel, an anchor, a connecting cable, a wave-breaking device and a main platform.

[0121] Among them, wave height monitors are arranged at equal intervals on the outer wall of the wave-breaking device to monitor the height of waves in different directions in real time over a long period of time, so as to judge the severity of the sea conditions and decide whether to activate the adaptive mooring system for the main platform.

[0122] The variable ballast tank is located inside the wave-breaking device, and the hatch is equipped with a one-way water inlet and one-way water outlet. The variable ballast tank controls the weight of the ballast water in the tank by opening the one-way water inlet and one-way water outlet to adjust the draft of the wave-breaking device according to different sea conditions.

[0123] A winch (wave-breaking device winch) is provided in the adaptive mooring storage cabin 204, in which a mooring cable (adaptive mooring cable) is stored; the adaptive mooring storage cabin is connected to the outside world via an anchoring channel, and the connection between the anchoring channel and the adaptive mooring storage cabin 204 is the entrance, and the connection with the outside world is the exit.

[0124] One end of the adaptive mooring cable 501 is connected to the wave-breaking device winch 502, and the other end is connected to the anchor 503. The anchor 503 is placed at the exit of the anchoring channel 205 and is restrained and fixed by the anchor stopper 504. When the anchor stopper 504 is opened, the anchor is freely released and falls into the seabed under the action of gravity, and is kept in position by the weight of the anchor and the action of the anchor claw and the sea soil. At this time, the adaptive mooring system is activated.

[0125] The connecting cable is a radially arranged lightweight cable connecting the wave absorbing device and the main platform. One end of the connecting cable is connected to a main platform winch 106, which is arranged in the main platform storage cabin at equal intervals in the annular direction. The other end of the connecting cable is connected to the anchor of the wave absorbing device.

[0126] Among them, the wave-breaking device winch 502 and the main platform winch 106 are both equipped with corresponding winch controllers, which can constrain or release the movement of the mooring cable. The adaptive mooring cable and the connecting cable can adjust the effective length through the wave-breaking device winch and the main platform winch respectively to achieve a relaxed or tensioned state as needed, which is also convenient for adjusting the pre-tension.

[0127] In order to more clearly understand the technical solution of the present invention, the technical solution of the present invention is described below in conjunction with specific embodiments.

[0128] Example

[0129] In the present invention, as mentioned above, the adaptive mooring system 5 includes a wave-breaking device winch 502 and a wave-breaking device winch controller 506, as well as an adaptive mooring line 501 and an anchor 503;

[0130] like Figure 4 As shown, the adaptive mooring system 5 needs to be used in coordination with a wave height monitor 201, a variable ballast tank 203, an adaptive mooring storage tank 204, an anchoring channel 205, an anchor 503, a connecting cable 207, a wave-breaking device 2 and a main platform 1.

[0131] In specific implementation, the floating photovoltaic wave energy power generation platform with a wave-breaking device provided by the present invention includes the following working modes:

[0132] The wave height in different directions is monitored in real time by the wave height monitor 201 to determine whether to activate the adaptive mooring system 4;

[0133] When the wave height continues to exceed the preset adaptive mooring system activation height within the preset system activation time length (e.g., 30 minutes), it is determined that the current sea condition where the platform is located is a dangerous sea condition, and the first operation is performed: the adaptive mooring system 4 is activated; otherwise, the second operation is performed: the adaptive mooring system 4 is not activated;

[0134] It should be noted that the enabling wave height of the adaptive mooring system is the wave height at which the main platform 1 is at risk of surging. It can be selected in advance based on the environmental conditions of the operating sea area or the user of the platform of the present invention, and can usually be a significant wave height under a sea condition that occurs once a year.

[0135] It should be noted that, when in use, the height of waves in different directions is monitored in real time by the wave height monitor 201, so as to judge the severity of the sea conditions and decide whether the main platform 1 activates the adaptive mooring system 4;

[0136] In specific implementation, when it is determined that the adaptive mooring system is not enabled, the second operation specifically includes the following contents:

[0137] The adaptive mooring cable 501 of the adaptive mooring system 5 is stored in the adaptive mooring storage compartment 204 of the wave-breaking device 2. One end of the adaptive mooring cable 501 is connected to the wave-breaking device winch 502 after passing through the wave-breaking device winch controller 506, and the other end is connected to the anchor 503. The anchor 503 is fixed and constrained at the exit of the anchoring channel 205 by the anchor stopper 504. At this time, the connecting cable 207 is radially arranged between the main platform 1 and the wave-breaking device 2. One end of the connecting cable 207 is connected to the anchor 503, and the other end of the connecting cable 207 is first connected to the main platform winch controller 107 and then connected to the main platform winch 106. The length of the connecting cable 207 is adjusted by the main platform winch 106 to ensure a relaxed state to prevent the movement of the wave-breaking device 2 from causing additional interference to the main platform 1.

[0138] In specific implementation, when it is determined that the adaptive mooring system 5 is activated, the first operation specifically includes the following contents:

[0139] The anchor stopper 504 and the wave-breaking device winch controller 506 are turned on, and the sunken anchor 503 is freely released and falls to the seabed under the action of gravity, and is kept in position by the weight and the interaction force between the anchor claw and the sea soil. The length of the adaptive mooring cable 501 is adjusted by the wave-breaking device winch 502, so that the adaptive mooring cable 501 is in a relaxed state, so as to avoid the wave-breaking device 2 from generating additional pulling force on the sunken anchor 503;

[0140] At the same time, the main platform winch controller 107 is turned on, and the length of the connecting cable 207 is adjusted through the main platform winch 106, so that the connecting cable 207 is in a tensioned state. At this time, the connecting cable 207 is equivalent to a tensioned mooring cable, which can significantly reduce the motion response of the main platform 1;

[0141] Among them, when it is determined to enable the adaptive mooring system 5, in order to compensate for the weight of the anchor 503 in the wave-breaking device 2, when the anchor 503 falls, the one-way water inlet gate 208 of the variable ballast tank 203 is opened, and seawater enters the variable ballast tank 203, thereby increasing the ballast weight of the wave-breaking device 2 and maintaining a constant draft.

[0142] It should be noted that when the wave height monitor 201 detects that the wave height is relatively large within a certain period of time, it is determined that the adaptive mooring system 5 is activated. Figure 5 As shown, hollow arrows indicate the moving directions of the adaptive mooring line 501 and the connecting line 207 when the adaptive mooring system 5 is activated.

[0143] In specific implementation, after performing the first operation (activating the adaptive mooring system 4), the following operations are also included:

[0144] When the wave height monitored in real time by the wave height monitor 201 is continuously lower than a preset adaptive mooring system deactivation height (e.g., a significant wave height under a sea condition with a return period of one year, or a height selected in advance by the user of the platform of the present invention) within a preset system deactivation time (e.g., 45 minutes), the adaptive mooring system deactivation operation is performed;

[0145] Adaptive mooring system deactivation operations include the following:

[0146] The main platform winch controller 107 is turned on, and the connecting cable 207 is in a relaxed state by adjusting the main platform winch 106. The wave-breaking device winch controller 506 is turned on, and the adaptive mooring cable 501 is in a tensioned state by adjusting the wave-breaking device winch 502, and the anchor 503 is pulled upward until the anchor 503 returns to the exit of the anchoring channel 205, so that the adaptive mooring cable 501 is retracted into the adaptive mooring storage tank 204. At this time, the anchor stopper 504, the wave-breaking device winch controller 506 and the main platform winch controller 107 are all closed (i.e., closed and locked), the one-way water outlet gate 209 of the variable ballast tank 203 is opened, and the seawater in the variable ballast tank 203 is discharged to maintain a constant draft, and the system as a whole returns to Figure 3 Normal operating status shown.

[0147] It should be noted that the preset adaptive mooring system deactivation height is equal to or less than the preset adaptive mooring system activation height.

[0148] It should be noted that if Figure 5 As shown, the solid arrows indicate the moving directions of the adaptive mooring cable 501 and the connecting cable 207 when the adaptive mooring system is deactivated. If the adaptive mooring system 5 has been activated, and when the wave height monitor 201 detects that the wave height is relatively small within a preset time length, it is determined that the activation (i.e. deactivation) of the adaptive mooring system 5 is terminated.

[0149] In a specific implementation, in order to avoid applying extra weight and causing the main platform 1 and the wave-breaking device 2 to tilt, the connecting cable 207 is made of lightweight polyester fiber material, and the adaptive mooring cable 501 is made of the same material.

[0150] In the present invention, in specific implementation, the photovoltaic panel power generation equipment 6 is a crystalline silicon solar cell module with mature existing technology, widespread application, and perfect packaging, which is used to absorb solar energy, generate solar energy and output it externally.

[0151] In the present invention, in terms of specific implementation, the wave energy device 3 is a mature and widely used device with existing technology, for example, it can be an oscillating float magnetohydrodynamic generator. The wave-breaking device 2 reciprocates under the action of waves and drives the generator (i.e., the oscillating float magnetohydrodynamic generator) to generate electricity, converting wave energy into electrical energy and outputting it to the outside.

[0152] Compared with the prior art, the floating photovoltaic wave energy power generation platform with a wave-breaking device provided by the present invention has the following beneficial effects:

[0153] 1. The present invention sets up an independently moored wave-breaking device around the floating photovoltaic main platform, utilizes the radiation wave-making and wave superposition principle, reduces the wave load, avoids equipment damage caused by platform waves, and improves the safety of the platform and the stability of photovoltaic power generation.

[0154] 2. The present invention realizes multi-energy complementation by adding a wave energy device to the wave absorbing device, thereby improving the utilization rate of the ocean space and further increasing the damping of the wave absorbing device, thereby reducing its motion response.

[0155] 3. The present invention also provides an adaptive mooring system that is activated when the waves are large. When the sea conditions are dangerous, tensioned mooring is added. This not only avoids the platform from capsizing or being damaged by waves, but also avoids the problem of being unable to adapt to tidal differences due to long-term use of tensioned mooring. At the same time, it reduces the use time of tensioned mooring and reduces the risk of fatigue damage.

[0156] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
