Abstract

The present invention provides an ocean floating body, an ocean floating body array with a breakwater, and a windbreak method. The ocean floating body can float on the sea surface, and a solar power generation assembly is installed on it. Initiated by the survival phenomenon of jellyfish, the ocean floating body can sink below the sea surface when large wind waves approach, thereby avoiding the large wind waves, and after the wind calms down, it will float back up to the sea surface on its own and continue solar power generation work. By controlling the reserve buoyancy of the ocean floating body array, the wind pressure from large wind waves will be made greater than the reserve buoyancy, thereby sinking below the sea surface to take refuge in extreme weather, and after the wind waves subside, it will return to the water surface due to the action of this reserve buoyancy. Furthermore, by installing an air chamber with a one-way intake valve, the stability of the ocean floating body and the impact resistance of the solar power generation assembly are further enhanced.

Description

Technical Field

[0001] The present invention relates to the field of offshore solar power generation, and specifically to ocean floating bodies, an ocean floating body array having a wave barrier, and a wind prevention method.

Background Art

[0002] With the development of solar power generation technology, solar power generation systems have been widely used in various fields. As the environmental protection problems in the petroleum and petrochemical industries become prominent, the issue of clean and green energy has been increasingly emphasized.

[0003] With the global development of the solar power generation industry, solar power generation has attracted increasing attention due to its advantages such as low cost and no pollution. The biggest difficulty of solar power generation is that, in fact, it requires a large amount of land area, and the increasingly high site cost may limit the further development of the solar power generation industry. In addition, arranging solar power generation equipment using a wide sea area for solar power generation is a new opportunity for the further development of the solar power generation industry. Currently, compared with the application of floating solar power generation on large reservoirs, lakes, fish ponds, etc., applying solar power generation on the sea surface on a large scale requires solving the actual offshore problems of high waves and ensuring that solar power generation products can experience large offshore wind waves (wind and waves) without being damaged.

[0004] The ocean has a vast area, much larger than the total area of land, and has rich development space. The applicant has already conducted intensive research on solar power generation equipment applied at sea and obtained preliminary results. However, the level of wind waves that can be dealt with is limited, and the corresponding equipment can adapt to general offshore wind waves, but there is still a risk of being damaged for relatively few large wind waves. Based on this, the present invention conducts further research on ocean floating bodies and corresponding wind prevention methods, expects to solve the above problems, and design ocean solar power generation floating body equipment that can safely resist rare large offshore wind waves.

Summary of the Invention

[0005] Based on the above technical background, the present inventors provide an ocean floating body, an ocean floating body array with a breakwater, and a windbreak method. The ocean floating body can float on the surface of the sea, and a solar power generation assembly is installed on it. Initiated by the survival phenomenon of jellyfish, the ocean floating body can sink below the surface of the sea when large wind waves approach, thereby avoiding the large wind waves, and after the wind calms down, it will float back up to the surface on its own and continue solar power generation work. By controlling the reserve buoyancy of the ocean floating body array, the wind pressure from large wind waves will be made greater than the reserve buoyancy, thereby allowing it to sink below the surface of the sea to take refuge in extreme weather, and after the wind waves subside, it will return to the surface due to the action of this reserve buoyancy. Furthermore, by installing an air chamber with a one-way intake valve, the stability of the ocean floating body and the impact resistance of the solar power generation assembly are further enhanced, thereby completing the present invention.

[0006] In a first aspect of the present invention, there is an ocean floating body including an air chamber, wherein the ocean floating body includes a wall surface that surrounds and forms the air chamber, the wall surface includes a top surface and side surfaces, a photovoltaic assembly is fixedly mounted above the top surface, and a one-way intake valve is provided on the side surfaces.

[0007] The aforementioned one-way intake valve is provided on the upper part of the side surface, Preferably, the one-way intake valves are provided in multiples, for example, 2-4, and are evenly distributed on the side. More preferably, two of the one-way intake valves are provided.

[0008] A floating plate is provided on the lower outer side of the aforementioned side surface, and the floating plate is integrally molded with the wall surface. Preferably, the ocean float has reserve buoyancy, that is, when the ocean float is completely submerged below the sea surface and its air chamber is filled with seawater, the buoyancy it experiences is greater than its own gravity. Preferably, the ocean floating body has a rectangular, triangular, or hexagonal outline in the horizontal plane, and preferably a square outline.

[0009] In a second aspect of the present invention, an ocean floating array having a breakwater, The ocean floating array includes an ocean floating body according to any one of the multiple claims 1 to 3, Preferably, two adjacent ocean floating bodies in the lateral and longitudinal directions are connected to each other so that the ocean floating array becomes a single unit.

[0010] A breakwater is constructed around the aforementioned floating ocean array.

[0011] The breakwater includes a plurality of hydrofoils connected to one another, The cross-sectional shape of the hydrofoil is airfoil, and the longitudinal section of the hydrofoil has a relatively large curvature at one end and a relatively small curvature at the other end, with the end with the relatively large curvature being the head and the end with the relatively small curvature being the tail, the head facing outwards from the ocean floating array and the tail facing inwards from the ocean floating array. Preferably, the lower surface of the hydrofoil is flat, the upper surface is streamlined, and the upper and lower surfaces are in contact with each other.

[0012] Circular connecting rings are provided in the middle of both the left and right ends of the hydrofoil, and two adjacent hydrofoils are fixedly connected by these connecting rings. The aforementioned connecting ring connects the ocean float and the hydrofoil.

[0013] The ocean floating array having a breakwater further includes an anchor fixing device, The anchor fixing device is connected to the hydrofoil by three wire ropes located below the hydrofoil, Preferably, a circular ring is further provided below the hydrofoil, and the bottom ends of the three wire ropes are all connected to the circular ring.

[0014] A connection point is provided in the middle of the tail portion of the hydrofoil. Of the three wire ropes, the top end of one is connected to a connecting ring on the left side of the hydrofoil, the top end of another is connected to a connecting ring on the right side of the hydrofoil, and the third is connected to the aforementioned connection point. Preferably, the length of the wire rope connected to the connection point is adjustable, and the angle of attack between the breakwater and the ocean waves can be adjusted according to the length of the wire rope.

[0015] A third aspect of the present invention relates to a method for windbreaking an ocean floating array, The windbreak method is implemented by an ocean floating body according to any one of claims 1 to 3 or an ocean floating body array according to any one of claims 4 to 9. In the above method, an ocean floating body or ocean floating body array is placed on the sea surface, a breakwater is arranged around it, and air remains in the air chamber. When wind and waves on the sea surface increase, the ocean floating structure sways violently in conjunction with the increase in wind and waves, the air in the air chamber is thrown out, the air chamber is filled with seawater, and the seawater continuously rises to the upper surface of the ocean floating structure array through the gaps in the array. As the amount of gas in the air chamber decreases, the amount of seawater on the upper surface of the floating ocean array gradually increases, and under the influence of the undulating ocean waves and sea surface wind pressure, the floating ocean array gradually sinks below the sea surface. When the wind and waves on the sea surface weaken, the frequency of the waves rising and falling decreases, the sea surface wind pressure decreases, and under the action of the reserve buoyancy, the ocean floating array gradually rises, and after the one-way intake valve is exposed above the water surface, outside air gradually enters the air chamber and fills the air chamber under the action of air pressure, providing a windbreak method.

Mode for carrying out the invention

[0018] Hereinafter, the present invention will be described in detail. The features and advantages of the present invention will become clearer from these descriptions.

[0019] The applicant has conducted relatively in - depth research in the field of offshore solar power generation, developed solar power generation equipment, ocean floating bodies, and wave - dissipating devices that can operate on the sea surface, and submitted corresponding patent applications. The applicant's prior equipment can resist waves at a certain level on the sea. In actual applications, in some sea areas, occasionally, waves with a higher level appear. Although the appearance frequency is low, it has been found that when they appear, the solar power generation equipment may be damaged. Based on this, the applicant has further intensively studied the solar power generation equipment and ocean floating bodies, and formed the present application.

[0020] According to a first aspect of the present invention, an ocean floating body is provided. As shown in FIG. 1, this ocean floating body includes an air chamber 1. When this ocean floating body is placed on the sea surface, the air chamber is arranged downward facing the sea surface. The top surface and the four - week side surfaces of the air chamber are sealed.

[0021] The wall surface that surrounds and forms the air chamber 1 includes a top surface 11 and side surfaces 12. A photovoltaic assembly is fixedly mounted above the top surface 11. The top surface 11 may be a sealed top surface or a partially open top surface. If the top surface is partially open, it can be sealed by mounting the photovoltaic assembly. This seals the top of the air chamber 1, preventing the air inside from overflowing from the top surface.

[0022] A one-way intake valve 2 is provided on the aforementioned side surface 12.

[0023] The one-way intake valve 2 is provided on the upper part of the side surface 12. Preferably, a plurality of the one-way intake valves 2, for example, 2 to 4, are provided and evenly distributed on the side surface 12.

[0024] More preferably, two of the one-way intake valves 2 are provided.

[0025] This intake valve is primarily used to draw air into the air chamber. Being a one-way valve, it cannot expel air; it can only draw it in. The intake valve has a diameter of approximately 1 cm, similar to a pencil. In actual use, the specific size can be determined by considering various factors such as the size of the float, its buoyancy, and the air chamber space to achieve optimal performance.

[0026] Preferably, a float plate 13 is provided on the lower outer side of the side surface 12. This float plate 13 is integrally molded with the wall surface. Furthermore, the ocean float is integrally molded as a whole and includes a housing that forms an air chamber in the middle and a float plate around the housing. The material of the ocean float is a high-molecular polymer, such as PE or PU resin materials, but is not limited to these. The high-molecular polymer mainly provides buoyancy and strength. In addition, to increase structural strength and improve wind wave resistance, a stronger skeletal structure is further provided inside the ocean float.

[0027] In the present invention, preferably, the horizontal contour shape of the ocean float is rectangular, triangular, or hexagonal, preferably square, and the overall structure is flattened. The air chamber is located directly below the middle of the ocean float, that is, the float plate 13 is evenly distributed around the side surface 12.

[0028] Preferably, the ocean float has reserve buoyancy. That is, when the ocean float is completely submerged below the sea surface and the air chamber 1 is filled with seawater, the buoyancy acting on the ocean float is greater than its own gravity. Here, the ocean float includes a solar power generation assembly. Preferably, the magnitude of the reserve buoyancy can affect the ascent speed of the ocean float. If the reserve buoyancy is large, the ascent speed is fast and the timing of ascent is earlier, while if the reserve buoyancy is small, the ascent speed is slow and the timing of ascent is delayed.

[0029] Preferably, the air chamber of the present invention constitutes part of the ocean floating suction cup structure. After the solar power generation assembly is horizontally attached to the ocean floating body, the middle of the underside of the ocean floating body is the air chamber, and the gas in the air chamber is sealed by the water surface. Under the combined action of the buoyancy of the ocean floating body and atmospheric pressure, the ocean floating body adheres to the water surface like a suction cup. When the ocean floating body encounters wind and waves of normal strength, for example, when the wave height is 2m or less, the buoyancy of the ocean floating body itself and the buoyancy of the air chamber prevent the ocean floating body from sinking into the water, and the action of atmospheric pressure prevents the entire body from detaching from the water surface, thus achieving an adhesion effect to the water surface and effectively improving wind and wave resistance. When the wind and wave level is higher than a predetermined strength level, for example, when the wave height is 2m or more and between 2 and 3, the rocking of the ocean floating body becomes violent, causing the air chamber to detach from contact with the water surface, and the gas in the air chamber is gradually ejected and filled with seawater. In such wind and wave conditions, the air chamber is gradually and completely filled with seawater. The floating body is gradually pushed below the sea surface under the action of wind pressure. In this invention, by providing appropriate reserve buoyancy and gaps for seawater to rise, the floating body is almost completely submerged by the time the wave height reaches 3m, thereby avoiding the effects of ocean waves of 3m or more on the floating body.

[0030] Preferably, the width of the float plate is 100-300 mm, and more preferably, the width is 150-200 mm.

[0031] In the present invention, the overall size of the ocean floating body is generally 6m*3m or less, preferably 3m to 1.5m. If the floating body is preferably square, the preferred size is 2m*2m. That is, preferably, the cross-section of the horizontal contour shape of the entire ocean floating body is square.

[0032] When the size of the ocean floating body of the present invention falls within the above range, the air chamber 1, the walls constituting the air chamber, and the float plate 13 can, as a whole, provide sufficient reserve buoyancy as a floating body structure, and for example, this ocean floating body can be stably floated on the sea surface when the wave height is 2m or less.

[0033] In a preferred embodiment of the present invention, the space within the air chamber is cylindrical, conical, or rectangular, and is preferably rectangular. Preferably, the cross-section of the air chamber is square, with side lengths of 1.4 m to 1.6 m.

[0034] If the size of the air chamber is too large, the buoyancy provided by the ocean float will not be sufficient to support the solar power generation assembly. If the size of the hollow section is too small, the "suction force" provided by the hollow section will be insufficient, resulting in poor adhesion of the solar power generation assembly to the water surface. When the size of the hollow section is within the above range, the hollow section can provide sufficient "suction force," allowing the ocean float to adhere to the water surface, providing relatively large buoyancy, and the combined action of the air chamber and the ocean float effectively improves the ocean float's wind and wave resistance capability.

[0035] In a preferred embodiment of the present invention, the upper surface of the float plate 13 has a striped or ripple-like pattern, which can be used as an anti-slip structure for workers walking on it, as well as a drainage structure, as shown in Figure 1.

[0036] The arc-shaped cross-section of the edge of the ocean floating structure reduces the impact of water currents, prevents damage from collisions between ocean floating structures, and is advantageous for opening and closing the structures.

[0037] The present invention further provides an ocean floating array having a breakwater. As shown in Figure 3, the ocean floating array includes a plurality of the ocean floating bodies.

[0038] Preferably, the ocean floating array is connected as a whole by connecting two adjacent ocean floating bodies to each other in the lateral and vertical directions. The overall structure of the connected ocean floating array is preferably a square structure, that is, the number of ocean floating bodies in the lateral and vertical directions is equal.

[0039] Multiple marine floating bodies are detachably connected to one another, preferably by one or two of the following: locking connections and sleeve connections, and more preferably by sleeve connections.

[0040] The ocean buoys described in this invention are not directly connected and fixed, but rather adjacent ocean buoys are connected by wire ropes. Multiple ocean buoys are connected to each other by connecting structures 5 located around the buoyancy plate 13, thereby forming an ocean buoy array. Adjacent ocean buoys can rotate relative to each other along a direction perpendicular to the wire ropes.

[0041] This connection method allows adjacent floating bodies to rotate around the wire rope within a certain range when subjected to the impact of water currents, thereby reducing damage to the floating bodies, solar power assemblies, and their connections caused by the impact of water currents.

[0042] In a preferred embodiment of the present invention, grooves 6 are provided around the lower layer member 2 of the ocean floating body, and a connecting structure 5 is provided in each groove 6. The connecting structure 5 is fitted onto a wire rope and used to connect ocean floating bodies to each other. The connecting structure 5 and the floating plate 13 of the ocean floating body are integrally connected (Figure 1).

[0043] The integrated connection improves the load-bearing effect of the connection structure 5, prevents rupture of the connection structure 5, and enhances the resistance and wind-wave resistance capabilities of the marine floating structure.

[0044] The number of grooves 4 on each side of the floating plate 13 is preferably 1 to 10, and more preferably 2 to 5.

[0045] The distance between adjacent grooves 4 on the floating plate 13 is the same, and the distance between adjacent grooves 4 is 400-700 mm, preferably 500-600 mm, and more preferably 550 mm.

[0046] In a more preferred embodiment of the present invention, the connection structure 5 includes a stainless steel sleeve pipe 51 and a connecting sheet 52. One side of the connecting sheet 52 is connected to the float plate 13, and the other opposite side is connected to the stainless steel sleeve pipe 51. The solar power carrier is fitted onto the wire rope by the stainless steel sleeve pipe 51 (Figure 3).

[0047] By using stainless steel sleeve tubing for installation, wear on the wire rope connection structure is avoided, extending its service life.

[0048] Preferably, each connection structure 5 includes one or two stainless steel sleeve pipes 51. When two stainless steel sleeve pipes are included, the two stainless steel sleeve pipes are located at both ends of the connection sheet 52, and the connection structure 5 is concave. When one stainless steel sleeve pipe is connected, the stainless steel sleeve pipe is located in the center of the connection sheet 52, and the connection structure 5 is convex, and the convex connection structure can be fitted into the concave connection structure (Figures 1 and 3).

[0049] Preferably, a concave connecting structure is provided on any two adjacent sides of the float plate 13. A convex connecting structure is provided on the other two sides. This arrangement ensures that the concave and convex connecting structures of two adjacent solar power carriers fit together, forming a hinge-like structure after being fitted onto the wire rope (Figure 3). When encountering wind and waves, the ocean float can rotate along a direction perpendicular to the wire rope, and because they fit together, when encountering wind and waves, adjacent ocean floats are displaced relative to each other in the axial direction of the wire rope, thus preventing them from swaying due to the wind and waves.

[0050] The above-described connection method of the present invention reduces damage to the ocean floating array and its connection parts caused by water current impacts, as the ocean floating array rotates within a certain range in a direction perpendicular to the wire rope when subjected to water current impacts.

[0051] In a preferred embodiment, as shown in Figure 4, a breakwater is provided around all four sides of the ocean floating array.

[0052] The breakwater includes a plurality of hydrofoils 3 that are connected to one another. The cross-sectional shape of the hydrofoil 3 is airfoil-shaped, and as shown in Figure 5, the longitudinal section of the hydrofoil 3 has a relatively large curvature at one end and a relatively small curvature at the other end. The end with the relatively large curvature is the head, and the end with the relatively small curvature is the tail. The head faces outward from the ocean floating array, and the tail faces inward from the ocean floating array.

[0053] Preferably, the underside of the hydrofoil is flat, the upper surface is streamlined, and the upper surface is in contact with the underside.

[0054] In this invention, the shape of the hydrofoil 3 is similar to that of an aircraft wing. The hydrofoil 3 provided in this invention has a certain buoyancy and mainly acts as a guide for airflow. According to the principle of Bernoulli's theorem, which is at work in the takeoff of an airplane, the lower layer of the wing is flat and the upper layer is rounded, and the air flowing along the surface of the wing flows faster on the upper side and slower on the lower side. Due to the Bernoulli effect, the pressure on the upper side of the wing is lower than the pressure on the lower side of the wing, and ultimately the aircraft gains upward lift and takes off. Similarly, both air and water are fluids, and when underwater waves collide with the hydrofoil, the pressure on the lower surface of the hydrofoil is greater than the pressure on the upper surface, generating upward lift, which in turn causes the hydrofoil to rise. On the other hand, an anchor is provided below the hydrofoil to firmly fix the entire breakwater to the seabed, transmitting the energy of the ocean waves to the seabed. The strong downward tensile force and the upward lift of the hydrofoil cancel each other out, thereby generating a wave-canceling force and achieving the objective of wave cancellation.

[0055] Preferably, the aspect ratio of the hydrofoil 3 is (5-8):4, and more preferably 6:4. The length of each hydrofoil 3 is 1-8m, and more preferably 2-3m. The length of the hydrofoil 3 is consistent with the side length of the ocean floating body having the float plate.

[0056] The width of the hydrofoil 3 can be appropriately set according to the hydrological conditions of the sea area where the ocean floating array is located, and preferably the width of the hydrofoil 3 is 0.75 m to 1.5 m. The hydrofoil 3 is made of a material such as PE, PU, ​​or resin.

[0057] In a preferred embodiment, circular connecting rings 4 are provided in the middle of both the left and right ends of the hydrofoil 3. These connecting rings 4 fix and connect two adjacent hydrofoils 3. In the present invention, in the horizontal direction, the end of the hydrofoil 3 closest to the ocean floating array is the head, i.e., the front end, the end furthest from the ocean floating array is the tail, i.e., the rear end, and the sides are the left end and the right end.

[0058] This connecting ring 4 connects the ocean float and the hydrofoil 3. By connecting with the connecting ring 4, the space between adjacent hydrofoils 3 and the ocean float can swing slightly, which allows the air in the air chamber to be smoothly displaced when wind waves are relatively large.

[0059] Furthermore, the circular connecting rings 4 provided at both ends of the hydrofoil 3 are used to connect the offshore floating body to the breakwater, including the hydrofoil. The connecting rings ensure that the tensile force is evenly distributed between each wire rope and between each hydrofoil 3, mitigating metal fatigue wear caused by prolonged oscillation of the connector due to wind and waves, increasing the movement space, extending the service life of the connector, and reducing maintenance and replacement costs. The connection between the wire rope and the circular connecting ring is secured by pressing with metal retaining ring hydraulic pliers. The connection rings on each wire rope are also tightened by pressing with metal retaining ring hydraulic pliers to prevent them from coming loose.

[0060] Preferably, the ocean floating array having a breakwater further includes an anchor fixing device. The anchor fixing device includes an anchor rope, an anchor chain, and an anchor.

[0061] The anchor fixing device is connected to the hydrofoil 3 by three root wire ropes located below the hydrofoil 3. Preferably, as shown in Figure 6, a circular ring is further provided below the hydrofoil 3. The bottom ends of the three wire ropes are all connected to this circular ring.

[0062] A connection point 7 is provided in the middle of the tail portion of the hydrofoil 3. Of the three wire ropes, one apex is connected to the left-side connecting ring 4 of the hydrofoil 3, another apex is connected to the right-side connecting ring 4 of the hydrofoil 3, and yet another is connected to the connection point 7. The three wire ropes form a triangular pyramidal linear structure (a triangular linear structure like a kite). The installation of the above triangular fixing point is a triangular stabilization device inspired by the triangular fixing of a kite.

[0063] Preferably, the length of the wire rope connected to connection point 7 is adjustable. The length of this wire rope adjusts the angle of attack between the breakwater and the waves. The longer the wire rope, the smaller the angle of attack between the breakwater and the waves, while the shorter the wire rope, the larger the angle of attack between the breakwater and the waves.

[0064] In this invention, the angle of attack of the breakwater is determined according to the hydrological conditions and wind and wave conditions of the water body where the floating body is located. Generally, in areas with large wind and wave conditions, the angle of attack is set to a small value, for example, 25-30 degrees, while in areas with small wind and wave conditions, the angle of attack is set to a large value, for example, 30-35 degrees. This setting is intended to make the solar power generation array more stable and to suit the hydrological conditions of the installation site. In this invention, the angle of attack is preferably set to 30 degrees.

[0065] The wire ropes at both ends transmit the tensile force from the array and the breakwater to the seabed via the anchor rope, anchor chain, and anchor of the anchor fixing device. In particular, when large wind waves appear and extreme weather is encountered, this breakwater acts as a guide for the array, sinking it below the surface and then bringing it back up to the surface once the wind waves subside. The water flow velocity at the bottom of the hydrofoil is slow, and the water flow velocity at the top is fast. Due to the action of its airfoil shape, it acts as a turbulent current, guiding the ocean current to the bottom of the array, reducing or eliminating resonance, providing wave-breaking and collision-preventing effects, and allowing the ocean floating array to sink underwater.

[0066] The present invention further provides a method for windbreaking an ocean floating array. This method is implemented using the above-described ocean floating array or ocean floating wall having an ocean floating structure or breakwater.

[0067] An ocean floating structure or array of ocean floating structures is placed on the sea surface, and a breakwater is placed around it. Air is left in air chamber 1. During the placement process, each ocean floating structure should be placed as horizontally as possible above the sea surface, and even if some seawater enters the air chamber, it will be gradually pushed back below the sea surface by the action of air pressure.

[0068] As the wind waves on the sea surface increase, the ocean floating bodies sway violently in response to the intensification of the wind waves, causing the air in the air chamber 1 to be shaken and the air chamber 1 to fill with seawater. The seawater seeps out from the gaps in the ocean floating body array onto the upper surface of the ocean floating body array. These gaps are the gaps between adjacent ocean floating bodies and also include the gaps formed in the floating plates 13.

[0069] As the amount of gas in air chamber 1 gradually decreases, the seawater on the upper surface of the ocean floating array gradually increases, and due to the action of the undulating ocean waves and the wind pressure on the sea surface, the ocean floating array gradually sinks below the sea surface. At this time, the ocean waves undulate violently up and down, continuously hitting the ocean floating, providing a downward force to the ocean floating. Combined with the wind pressure and the gravity of the seawater, the ocean floating continuously acquires a vertically downward force, and further acquires downward acceleration and velocity, causing the ocean floating to completely sink below the sea surface. Due to the continuous up and down action of the ocean waves, the ocean floating is continuously subjected to a large vertical force, causing it to reciprocate vertically, and the ocean floating is almost always in a shallow position below the sea surface due to its reserve buoyancy, thereby achieving the purpose of self-protection and preventing excessive sinking.

[0070] As the wind and waves on the sea surface weaken, the frequency of vertical wave movement decreases, reducing the wind pressure on the sea surface. Due to the effect of reserve buoyancy, the ocean floating array gradually rises. At this time, the frequency of vertical wave movement on the sea surface weakens, and the vertical downward force applied to the ocean floating array with each movement weakens, becoming smaller than the reserve buoyancy of the ocean floating array. After the one-way intake valve 2 is exposed above the water surface, external air gradually enters the air chamber 1 due to the effect of air pressure, filling the air chamber 1. The filling of the air chamber and the reserve buoyancy of the floating array itself improve both the stability and overall impact resistance of the ocean floating array, protecting the solar power generation assembly from damage.

[0071] The present invention has the following beneficial effects. (1) The ocean float of the present invention has an air chamber, and under the combined action of the buoyancy of the ocean float and atmospheric pressure, it forms an integrated suction cup structure, allowing the ocean float to adhere closely to the water surface like a suction cup. At the same time, the ocean float has reserve buoyancy, and when the solar power generation assembly and the ocean float encounter weak wind waves, the reserve buoyancy of the ocean float prevents the float from sinking into the water, and the action of atmospheric pressure prevents the entire structure from separating from the water surface, thereby achieving an effect of adhering closely to the water surface and increasing the wind wave resistance capacity of the ocean float. (2) The air chamber of the marine floating body described in the present invention is provided with a one-way intake valve, which allows air to be gradually supplied when water is supplied to the air chamber, ensuring that the air chamber always has a strong adsorption capacity. (3) The ocean floating body described in the present invention has a predetermined reserve buoyancy, and the air chamber has a predetermined stability and wind wave resistance performance. If the wind wave level is too high, the air inside the air chamber is blown out of the air chamber, and the air chamber is filled with seawater, further reducing the buoyancy of the ocean floating body. Furthermore, if the wind pressure is sufficiently high, the entire ocean floating body is pushed below the sea surface, preventing damage to the ocean floating body and the solar power generation assembly from large wind waves. (4) The ocean floating array of the present invention is equipped with a breakwater, which acts as an array steering mechanism. By moving the array up and down the sea surface, it improves the sinking speed when avoiding large wind waves and also increases the surfacing speed. This breakwater can also eliminate resonance and has the effect of wave protection and collision prevention. (5) The lower part of the hydrofoil of the breakwater on the floating body of the ocean described in the present invention is connected to an anchor fixing device via three wire ropes, and the installation positions of the three wire ropes form a triangle, so that the three wire ropes form a triangular stabilization device, improving the stability of the hydrofoil, and connecting rings are installed at the specific connection points so that the tensile force between each wire rope is distributed in a balanced manner and the metal fatigue wear caused by the connection body swaying for a long time due to wind waves is mitigated.
