Description

Technical Field

[0001] The invention belongs to the technical field of seawater wave protection, and in particular relates to a floating permeable breakwater suitable for seagrass bed ecological maintenance. Background Art

[0002] Seagrass beds play a very important role in the marine ecosystem and are usually distributed in shallow sea areas. The ecological restoration and maintenance of seagrass beds involves replanting or replenishing degraded seagrasses. Since seagrass is easily lost due to the impact of seawater surges in the early stages of sowing and planting, wave-breaking measures are needed in seagrass bed restoration projects. The specific wave-breaking measures are to build fixed breakwaters or floating breakwaters. Since fixed breakwaters are difficult to construct, costly, and cannot be relocated, floating breakwaters are currently used for seagrass bed restoration and maintenance projects.

[0003] The common floating breakwaters currently rely entirely on floating buoys to weaken the waves on the sea surface, but the undercurrents below the sea surface cannot be eliminated. Therefore, they cannot provide the expected protection for seagrasses planted on the seabed and need further improvement. In addition, how to reasonably utilize the energy of seawater fluctuations while reasonably preventing waves, thereby improving the green energy effect of seagrass bed ecological conservation projects, is also a current key research and development direction. Summary of the invention

[0004] The embodiment of the present invention provides a floating permeable breakwater suitable for seagrass bed ecological maintenance, aiming to enhance the seawater wave-breaking effect of the floating breakwater and improve the green energy effect of the seagrass bed ecological maintenance project.

[0005] To achieve the above object, the technical solution adopted by the present invention is: to provide a floating permeable breakwater suitable for seagrass bed ecological conservation, comprising:

[0006] The base is used for horizontal anchoring on the seabed, and columns are respectively provided at both ends of the base, and each column is sleeved with an elastic element;

[0007] The anti-wave buoy is used to float on the sea surface, and its two ends are connected to two pillars by sliding up and down respectively;

[0008] A crossbeam is located below the anti-wave float, and its two ends are respectively connected to the two columns by sliding up and down, and the crossbeam is used to press the elastic element downward;

[0009] The horizontal rotor has two ends rotatably connected to the bottom ends of the two columns respectively. The horizontal rotor has a plurality of wave-breaking belts spaced along its axial direction. The wave-breaking belt is wound around the horizontal rotor and one end of the wave-breaking belt extends upward and is connected to the crossbeam, and the other end of the wave-breaking belt extends upward and is connected to the wave-breaking float;

[0010] A generator is disposed on the base and connected to the horizontal rotor;

[0011] Among them, the wave-breaking buoy floats up and down based on the fluctuations of the sea surface, and drives the horizontal rotor to rotate in one direction through each wave-breaking belt.

[0012] In a possible implementation, the horizontal rotor includes:

[0013] The first rotating shaft has two ends respectively passing through the bottom ends of the two columns and rotatingly cooperating with the columns;

[0015] A plurality of belt-winding wheels are respectively mounted on the one-way bearings, and one wave-breaking belt is respectively wound on each belt-winding wheel;

[0016] Among them, when the wave-breaking float floats up to make the belt winding wheel rotate forwardly under the traction of the wave-breaking belt, the one-way bearing drives the first rotating shaft to rotate forward synchronously. When the wave-breaking float sinks to make the belt winding wheel reverse under the traction of the wave-breaking belt, the one-way bearing reverses alone relative to the first rotating shaft.

[0017] In some embodiments, at least one end of the first rotating shaft is mounted with an inertia flywheel.

[0018] Exemplarily, the anti-wave buoy includes:

[0019] The floating frame has telescopic rods extending downwards at both ends, the two telescopic rods are slidably penetrated through the two uprights, the floating frame has a second rotating shaft connected to the horizontal rotor, and each wave-breaking belt is connected to the floating frame;

[0020] A plurality of buoys are sequentially and adjacently mounted on the second rotating shaft along the axial direction of the second rotating shaft, and each buoy is used for self-rotation while floating in seawater and driving the second rotating shaft to rotate in one direction.

[0021] For example, a plurality of movable valve plates are provided in the buoy, each of which divides the inner cavity of the buoy into a plurality of circumferentially adjacent sector cavities; a plurality of water permeable openings are spaced apart on the peripheral wall of the buoy, each of which is connected to a corresponding sector cavity, and the water permeable openings and the movable valve plates are respectively located at the circumferential ends of the sector cavity; wherein, when the buoy floats up with the sea surface and the movable valve plate is located below the water permeable opening and submerged in the sea water, the movable valve plate opens toward the inside of the sector cavity under the push of the sea water.

[0022] In some embodiments, the inner wall of the float is provided with limiting ribs at the edge of each water permeable port, and one end of the movable valve plate is hinged to the inner wall of the float; a spring plate is provided between the movable valve plate and the wall of the fan cavity, and the spring plate is used to drive the other end of the movable valve plate to overlap the limiting ribs to form a closed state; a bubble is provided on the side of the movable valve plate facing away from the fan cavity.

[0023] Exemplarily, the water permeable openings of each buoy are staggered and distributed in sequence along the circumference of the buoy.

[0024] In a possible implementation, the floating permeable breakwater suitable for seagrass bed ecological conservation further includes a transmission assembly, which includes:

[0025] A first transmission wheel, mounted on the second rotating shaft;

[0026] The second transmission wheel is mounted on the horizontal rotor and connected to the first transmission wheel through a transmission chain;

[0027] The tensioning member is arranged on the column and connected with the transmission chain. The tensioning member is used to keep the transmission chain in a tensioned state when the wave-breaking float rises and falls.

[0028] By way of example, the tensioning element includes:

[0030] The tensioning frame has a middle portion rotatably connected to the connecting shaft, and both ends are rotatably connected to tensioning wheels, which are meshed and connected with the transmission chain;

[0031] The connecting rod has one end hinged to the tensioning frame and the other end hinged to the telescopic rod. The connecting rod is used to drive the tensioning frame to swing when the telescopic rod is raised or lowered.

[0032] In some embodiments, a wave-breaking block is provided at a portion of the wave-breaking belt between the horizontal rotor and the wave-breaking float.

[0033] The floating permeable breakwater suitable for seagrass bed ecological maintenance provided by the present invention has the following beneficial effects: compared with the prior art, the floating permeable breakwater suitable for seagrass bed ecological maintenance of the present invention anchors the base to the seabed and uses the columns on the base to connect the wave-breaking buoys that float up and down with the fluctuation of sea water, thereby weakening the waves on the sea surface, and at the same time, using a plurality of wave-breaking belts connected between the wave-breaking buoys and the horizontal rotors to separate and weaken the undercurrents under the sea surface, thereby improving the seawater wave-breaking effect and providing effective protection for the seagrass planted on the seabed; using elastic elements to form a crossbeam Elastic pushing effect, when the wave-breaking float falls with the sea level, the elastic element pushes the crossbeam upwards and pulls one end of the wave-breaking belt; when the wave-breaking float rises with the sea level, the wave-breaking float pulls the other end of each wave-breaking belt upwards and makes the crossbeam compress the elastic element downwards, thereby, on the one hand, maintaining the taut state of each wave-breaking belt, thereby improving the seawater wave-breaking effect; on the other hand, each wave-breaking belt can be used to jointly drive the horizontal rotor to rotate, thereby providing torque output to the generator, so that the energy of seawater fluctuations is converted into electrical energy, thereby improving the green energy effect of the seagrass bed ecological maintenance project.

DETAILED DESCRIPTION

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] It should be noted that when an element is referred to as being "disposed on" or "connected to" another element, it may be directly on the other element or indirectly on the other element. It should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "top", "bottom", "inside", "outside", etc. is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. The terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, the meanings of "multiple" and "several" are two or more, unless otherwise clearly and specifically defined.

[0042] Please also read Figures 1 to 5 The floating permeable breakwater suitable for seagrass bed ecological maintenance provided by the present invention is now described. The floating permeable breakwater suitable for seagrass bed ecological maintenance includes a base 10, a wave-breaking float 20, a crossbeam 30, a horizontal rotor 40, and a generator 60; the base 10 is used for horizontal anchoring on the seabed, and columns 11 are respectively provided at both ends of the base 10, and each column 11 is sleeved with an elastic element 12; the wave-breaking float 20 is used to float on the sea surface, and the two ends are respectively connected to the two columns 11 by sliding up and down; the crossbeam 30 is located below the wave-breaking float 20, and the two ends are respectively connected to the two columns 11 by sliding up and down, and the crossbeam 30 is used to float on the sea surface ... The elastic element 12 is pressed downward; the two ends of the horizontal rotor 40 are respectively rotatably connected to the bottom ends of the two columns 11, and the horizontal rotor 40 has a plurality of wave-breaking belts 50 distributed along its axial direction. The wave-breaking belt 50 is wound around the horizontal rotor 40 and one end extends upward and is connected to the beam 30, and the other end extends upward and is connected to the wave-breaking buoy 20; the generator 60 is arranged on the base 10 and is connected to the horizontal rotor 40; wherein the wave-breaking buoy 20 floats up and down based on the fluctuation of the sea surface, and drives the horizontal rotor 40 to rotate unidirectionally through each wave-breaking belt 50.

[0043] It should be noted that, in the present embodiment, the elastic element 12 can be specifically a spring. Considering that the generator 60 needs to be driven by unidirectional rotation, a ratchet pawl mechanism or a one-way bearing 42 can be provided on the horizontal rotor 40 corresponding to each wave-breaking belt 50. Taking the ratchet pawl mechanism as an example, the wave-breaking belt 50 is wound on the ratchet. When the sea level rises and drives the wave-breaking buoy 20 to rise, the wave-breaking buoy 20 pulls each wave-breaking belt 50 upward, and at the same time, the other end of each wave-breaking belt 50 pulls the crossbeam 30 downward to make the elastic element The component 12 is compressed to store energy. At the same time, since the wave-breaking belt 50 is wound on the horizontal rotor 40 (ratchet), the horizontal rotor 40 rotates driven by the wave-breaking belt 50. When the sea level drops and drives the wave-breaking buoy 20 to descend, the traction force of the wave-breaking buoy 20 on each wave-breaking belt 50 decreases. The elastic element 12 releases elastic potential energy and pushes the cross beam 30 upward, so that the cross beam 30 pulls each wave-breaking belt 50 upward. At this time, the wave-breaking belt 50 does not output reverse power to the horizontal rotor 40 (only drives the ratchet to reverse). Therefore, the horizontal rotor 40 is pulled by the wave-breaking belt 50 to form a one-way rotation by the up and down floating of the wave-breaking buoy 20, thereby driving the generator 60 to work.

[0044] It should be explained that, compared with the anchor chain traction method of conventional floating breakwaters, it constantly changes from tight to loose and from loose to tight during the floating process of the float, which is not only not conducive to the stability of the float, but also the anchor chain is easily damaged; in this embodiment, based on the energy storage and release of the elastic element 12, the wave-breaking belt 50 is always kept in a taut state, thereby avoiding the sudden change of the tension of the wave-breaking belt 50, thereby improving the floating stability of the wave-breaking buoy 20 and the service life of each wave-breaking belt 50, and at the same time, the spaced wave-breaking belts 50 can be used to form a grid-type permeable structure, thereby separating and weakening the undercurrent energy under the sea surface.

[0045] It should be noted that in this embodiment, a sealed waterproof box is provided on the base 10, and the generator 60 is arranged in the waterproof box. One end of the horizontal rotor 40 is sealed and penetrates into the waterproof box and is connected to the generator 60, thereby preventing the generator 60 from being exposed to water and affecting its life, and at the same time avoiding leakage problems.

[0046] Compared with the prior art, the floating permeable breakwater suitable for seagrass bed ecological maintenance provided in this embodiment anchors the base 10 to the seabed and uses the columns 11 on the base 10 to connect the wave-breaking buoys 20 that float up and down with the fluctuations of the sea water, thereby weakening the waves on the sea surface. At the same time, the multiple wave-breaking belts 50 connected between the wave-breaking buoys 20 and the horizontal rotors 40 can separate and weaken the undercurrents under the sea surface, thereby improving the seawater wave-breaking effect and providing effective protection for the seagrass planted on the seabed. The elastic element 12 is used to form an elastic pushing effect on the crossbeam 30. When the wave-breaking buoy 20 floats up and down with the fluctuations of the sea water, the undercurrents under the sea surface can be separated and weakened. When the wave-breaking buoy 20 rises with the sea level, the wave-breaking buoy 20 pulls the other end of each wave-breaking belt 50 upward and causes the beam 30 to compress the elastic element 12 downward. On the one hand, this can keep each wave-breaking belt 50 taut, thereby improving the seawater wave-breaking effect. On the other hand, each wave-breaking belt 50 can be used to jointly drive the horizontal rotor 40 to rotate, thereby providing torque output to the generator 60, so that the energy of seawater fluctuations is converted into electrical energy, thereby improving the green energy effect of the seagrass bed ecological conservation project.

[0047] In some embodiments, see Figure 1 and Figure 2 The horizontal rotor 40 includes a first rotating shaft 41, a plurality of one-way bearings 42 and a plurality of belt-winding pulleys 43; the two ends of the first rotating shaft 41 are respectively passed through the bottom ends of the two columns 11 and are rotatably matched with the columns 11; the one-way bearings 42 are sequentially sleeved on the first rotating shaft 41 along the axial direction of the first rotating shaft 41; the belt-winding pulleys 43 are respectively and correspondingly sleeved on the one-way bearings 42, and one of the wave-breaking belts 50 is respectively wound around each belt-winding pulley 43; wherein, when the wave-breaking float 20 floats up to make the belt-winding pulley 43 rotate forwardly under the traction of the wave-breaking belt 50, the one-way bearing 42 drives the first rotating shaft 41 to rotate forward synchronously, and when the wave-breaking float 20 sinks to make the belt-winding pulley 43 reverse under the traction of the wave-breaking belt 50, the one-way bearing 42 reverses independently relative to the first rotating shaft 41.

[0048] The one-way bearing 42 is also called an overrunning clutch, which is a bearing that can rotate freely in one direction and is locked in another direction. Here, the one-way bearing 42 is used to install the belt pulley 43 on the first rotating shaft 41, so that the positive driving energy of the wave-breaking belt 50 on the belt pulley 43 can be transmitted to the first rotating shaft 41, and the reverse driving energy of the wave-breaking belt 50 on the belt pulley 43 can be prevented from being transmitted to the first rotating shaft 41, thereby converting the positive and negative bidirectional rotational motion of the wave-breaking belt 50 on the belt pulley 43 into a continuous one-way rotational motion of the first rotating shaft 41, so that the first rotating shaft 41 drives the generator 60 to work stably.

[0049] In this embodiment, a spiral groove is provided on the belt winding wheel 43, and the wave-breaking belt 50 is wound in the spiral groove for three to five turns. Under normal circumstances, the wave-breaking belt 50 is in a taut state, and the friction between the wave-breaking belt 50 and the groove wall of the spiral groove can ensure that the belt winding wheel 43 can rotate stably driven by the wave-breaking belt 50. Considering that the humid underwater environment may cause the wave-breaking belt 50 and the belt winding wheel 43 to slip, the midpoint position of the wave-breaking belt 50 wound on the spiral groove is fixed, thereby not affecting the winding or unwinding of the wave-breaking belt 50 on the belt winding wheel 43, and can also avoid the slipping of the wave-breaking belt 50.

[0050] It should be noted that if Figure 2 As shown, at least one end of the first rotating shaft 41 is provided with an inertia flywheel 44. Since the rising and falling energy of the wave-breaking float 20 is intermittently transmitted to the first rotating shaft 41 through the wave-breaking belt 50 in cooperation with the one-way bearing 42, the driving force of the first rotating shaft 41 cannot be continuous, which will cause the problem of unstable speed. Therefore, the inertia flywheel 44 is arranged on the first rotating shaft 41. When the wave-breaking float 20 rises and drives the first rotating shaft 41 to rotate forward, the inertia flywheel 44 rotates to store energy. When the wave-breaking float 20 falls, the inertia flywheel 44 releases energy to ensure that the first rotating shaft 41 can rotate continuously and stably, thereby improving the rotation stability of the first rotating shaft 41, and further ensuring the stable operation of the generator 60.

[0051] It should be understood here that since the rotation speed of the first rotating shaft 41 is relatively low, the rotation of the inertia flywheel 44 has little effect on the disturbance of the seawater, and the inertia flywheel 44 has a smooth peripheral wall, which not only has little resistance from seawater, but also can further reduce the disturbance of seawater; of course, a sealing cover can also be provided on the base 10, and the inertia flywheel 44 can be arranged inside the sealing cover, thereby avoiding contact between the inertia flywheel 44 and seawater, thereby reducing the rotational resistance of the inertia flywheel 44, and then improving energy utilization.

[0052] As a specific implementation of the above-mentioned anti-wave buoy 20, please refer to Figures 1 to 5 The wave-breaking float 20 includes a floating frame 21 and a plurality of buoys 22; wherein, downwardly extending telescopic rods 211 are respectively provided at both ends of the floating frame 21, and the two telescopic rods 211 are respectively slidably penetrated through the two columns 11, and the floating frame 21 has a second rotating shaft 212 which is transmission-connected with the horizontal rotor 40, and each wave-breaking belt 50 is respectively connected to the floating frame 21; each buoy 22 is sequentially and adjacently mounted on the second rotating shaft 212 along the axial direction of the second rotating shaft 212, and each buoy 22 is used for self-rotation while floating in the sea water and driving the second rotating shaft 212 to rotate unidirectionally.

[0053] The column 11 can be provided with a sliding hole along its axial direction, and the telescopic rod 211 is slidably inserted into the sliding hole, and the connection is stable and reliable; because the sea water not only has ups and downs, but also the waves have impact force in the horizontal direction, the impact of the waves on the buoy 22 is utilized to drive the buoy 22 to drive the second rotating shaft 212 to rotate, and then the torque is transmitted to the first rotating shaft 41 through the second rotating shaft 212, which can not only improve the driving force of the first rotating shaft 41 on the generator 60, but also improve the power continuity of the first rotating shaft 41, thereby improving the conversion and utilization rate of the sea water wave energy and enhancing the green energy effect of the wave-breaking project.

[0054] For some possible implementations, see Figure 4 and Figure 5 The buoy 22 is provided with a plurality of movable valve plates 221, each of which divides the inner cavity of the buoy 22 into a plurality of circumferentially adjacent sector cavities 222; a plurality of water permeable openings 223 are spaced apart on the peripheral wall of the buoy 22, each of which is connected to a corresponding sector cavity 222, and the water permeable openings 223 and the movable valve plates 221 are respectively located at the circumferential ends of the sector cavity 222; when the buoy 22 floats on the sea surface and the movable valve plate 221 is located below the water permeable opening 223 and submerged in the sea water, the movable valve plate 221 is pushed by the sea water and opens toward the inside of the sector cavity 222.

[0055] Since the impact force on the buoy 22 in the horizontal direction during the wave of sea water is a reciprocating impact, it is difficult to meet the unidirectional rotation power requirement by simply relying on the impact force to drive the buoy 22 to rotate. Therefore, a movable valve plate 221 is set inside the float, and one of the sector chambers 222 is used for illustration.

[0056] like Figure 4 As shown in the figure, when the fan chamber 222 is at an angle where its water permeable opening 223 is higher than the movable valve plate 221, when the waves on the sea surface surge and drive the buoy 22 to float up, the seawater is pushed upward from the water permeable opening 223 on the lower side of the movable valve plate 221 of the fan chamber 222 by utilizing the upwelling power of the seawater, so that the movable valve plate 221 is opened and the seawater enters the fan chamber 222; when the waves on the sea surface recede and cause the buoy 22 to descend, the movable valve plate 221 is moved along with the buoy 2 2, and the seawater is pressed down by the sinking process of the fan chamber 222, thereby causing the seawater to generate a reverse thrust force on the movable valve plate 221, so that the movable valve plate 221 is opened again, and the fan chamber 222 is continuously filled with water with the continuous rise and fall of waves, forming a water storage state in which the water surface inside the fan chamber 222 is higher than the sea surface; when the fan chamber 222 is at an angle where its water permeable port 223 is lower than the movable valve plate 221, the seawater in the fan chamber 222 is discharged from the water permeable port 223, so the water surface inside the fan chamber 222 can only be lower than the sea surface or flush with the sea surface.

[0057] like Figure 5As shown, when the thrust of seawater on the movable valve plate 221 is lower than the closing force of the movable valve plate 221 (elastic force of the spring 225), usually when the buoy 22 fluctuates with the seawater to the crest or trough, the movable valve plate 221 is closed.

[0058] Since each sector cavity 222 has the same water intake and discharge process as mentioned above, a gravity difference is generated on both sides of the buoy 22 based on the difference of seawater in each sector cavity 222, thereby driving the second rotating shaft 212 to rotate unidirectionally. Especially for the small-amplitude and high-frequency fluctuation characteristics of seawater in shallow sea areas, the movable valve plate 221 is opened and closed with the waves during the up and down floating of the buoy 22, so as to ensure the continuity and stability of the rotational drive of the buoy 22 by the seawater fluctuation energy, which can not only improve the conversion and utilization rate of the seawater fluctuation energy, but also assist the rotational drive of the first rotating shaft 41, thereby improving the rotational stability and continuity of the first rotating shaft 41, and then improving the working stability of the generator 60.

[0059] It should be explained that the principle of the transmission connection between the second rotating shaft 212 and the first rotating shaft 41 to stabilize the rotational speed of the first rotating shaft 41 is that when the rotational speed of the first rotating shaft 41 decreases, the second rotating shaft 212 supplements the torque to the first rotating shaft 41 based on the rotational drive of each buoy 22, so that the first rotating shaft 41 maintains the current rotational speed. When the rotational speed of the first rotating shaft 41 increases, the second rotating shaft 212 forms a reverse restriction on the torque of the first rotating shaft 41. Specifically, during the rotation of the buoy 22, seawater enters the fan cavity 222 through each water permeable port 223 (the faster the rotational speed, the faster the speed and frequency of seawater entering the fan cavity 222) to generate rotational resistance to the buoy 22, so that the first rotating shaft 41 maintains the current rotational speed. On this basis, it can cooperate with the inertia flywheel 44 to ensure the rotational stability of the first rotating shaft 41 to the greatest extent, thereby improving the working stability of the generator 60.

[0060] For details, see Figure 2 The inner wall of the above-mentioned float 22 is respectively provided with limiting ribs 224 at the edge of each water permeable port 223, and one end of the movable valve plate 221 is hinged to the inner wall of the float 22; a spring sheet 225 is provided between the movable valve plate 221 and the cavity wall of the sector cavity 222, and the spring sheet 225 is used to drive the other end of the movable valve plate 221 to overlap the limiting rib 224 to form a closed state; a bubble 226 is provided on the side of the movable valve plate 221 away from the sector cavity 222.

[0061] Here, an arc-shaped or V-shaped spring sheet 225 is used to apply elastic thrust to the movable valve plate 221, so that the movable valve plate 221 remains in a closed state in contact with the limiting rib 224. When the thrust of seawater on the movable valve plate 221 exceeds the elastic force of the spring sheet 225, the movable valve plate 221 can be pushed open to allow water to flow into the sector chamber 222 (such as Figure 4As shown in FIG. 2 ), as the thrust of seawater on the movable valve plate 221 gradually decreases, the spring piece 225 pushes the movable valve plate 221 back to restore the state as shown in FIG. Figure 5 The closed state shown in the figure completes a water intake process; for the sector cavity 222 whose water permeable port 223 is lower than the movable valve plate 221, due to the abutment and limiting effect of the limiting rib 224, the thrust of the rising and falling sea water on the movable valve plate 221 cannot open the movable valve plate 221, thereby ensuring the water level difference in the sector cavity 222 on both sides of the second rotating shaft 212 of the buoy 22, thereby ensuring that the buoy 22 drives the second rotating shaft 212 to rotate continuously and stably under the action of the gravity difference on both sides thereof.

[0062] In order to ensure that the seawater has sufficient force to push the movable valve plate 221 to open, especially when the sea surface is relatively calm, a bubble 226 is provided on the movable valve plate 221. The buoyancy of the seawater on the bubble 226 can be utilized to assist the movable valve plate 221 in opening, thereby avoiding the problem that the movable valve plate 221 cannot be opened due to insufficient thrust generated by the fluctuation of the seawater, thereby causing the buoy 22 to stop rotating.

[0063] Please note that, see Figures 1 to 5 In this embodiment, the water permeable openings 223 of each buoy 22 are staggered in sequence along the circumference of the buoy 22. Since the number of the sector cavities 222 of a single buoy 22 is limited, the circumferential connection angles of each buoy 22 on the second rotating shaft 212 are staggered, thereby making the sector cavities 222 inside each buoy 22 staggered in sequence, and of course, the water permeable openings 223 of each buoy 22 are staggered in sequence accordingly. Specifically, when each buoy 22 overlaps in the axial direction, all the water permeable openings 223 completely occupy the circumferential wall of the buoy 22, thereby ensuring that each buoy 22 can be continuously driven by seawater fluctuations after being combined into one, thereby improving the continuity and stability of the rotational power of the second rotating shaft 212.

[0064] It is important to understand that see Figures 1 to 3 The above-mentioned floating permeable breakwater suitable for seagrass bed ecological maintenance also includes a transmission assembly 70, which includes a first transmission wheel 71, a second transmission wheel 72 and a tensioner 74; wherein the first transmission wheel 71 is sleeved on the second rotating shaft 212; the second transmission wheel 72 is sleeved on the horizontal rotor 40, and is connected to the first transmission wheel 71 through a transmission chain 73; the tensioner 74 is arranged on the column 11 and is connected to the transmission chain 73, and the tensioner 74 is used to keep the transmission chain 73 in a tensioned state when the wave-breaking float 20 rises and falls.

[0065] Taking into account the transmission stability and anti-skid performance, a chain drive is adopted herein, that is, the first transmission wheel 71 and the second transmission wheel 72 are both sprockets, and the transmission chain 73 is a chain; of course, a belt drive can also be adopted, in which the first transmission wheel 71 and the second transmission wheel 72 are both belt wheels, and the transmission chain 73 is an anti-skid chain belt; the first transmission wheel 71 transmits the torque to the second transmission wheel 72 through the transmission chain 73, thereby realizing the power compensation or restriction of the horizontal rotor 40 by the second rotating shaft 212, and at the same time, the tensioning member 74 is used to adaptively tension the transmission chain 73 during the process of the wave-breaking buoy 20 rising and falling following the fluctuations of the sea water, so as to prevent the transmission chain 73 from falling off and improve the transmission stability.

[0066] For example, Figure 3 As shown, the tensioning member 74 includes a connecting seat 741, a tensioning frame 742, and a connecting rod 744; wherein the connecting seat 741 is mounted on the column 11 and is located above the crossbeam 30, and the connecting seat 741 is provided with a connecting shaft along the axial direction of the second rotating shaft 212; the middle part of the tensioning frame 742 is rotatably connected to the connecting shaft, and the two ends are respectively rotatably connected to the tensioning wheels 743, and the tensioning wheels 743 are meshed and connected with the transmission chain 73; one end of the connecting rod 744 is hinged to the tensioning frame 742, and the other end is hinged to the telescopic rod 211, and the connecting rod 744 is used to drive the tensioning frame 742 to swing when the telescopic rod 211 is raised or lowered.

[0067] When the wave-breaking buoy 20 rises with the fluctuation of the sea surface and increases the distance between it and the horizontal rotor 40, the telescopic rod 211 pulls one end of the tensioning frame 742 upward through the connecting rod 744 to make the tensioning frame 742 swing, so that the horizontal distance between the two tensioning wheels 743 is reduced, thereby allowing the transmission chain 73 to meet the requirement of increasing the distance between the first transmission wheel 71 and the second transmission wheel 72. When the wave-breaking buoy 20 decreases with the fluctuation of the sea surface and reduces the distance between the first transmission wheel 71 and the second transmission wheel 72, the telescopic rod 211 is lowered. The connecting rod 744 pushes one end of the tensioning frame 742 downward to make the tensioning frame 742 swing in the opposite direction, thereby increasing the horizontal distance between the two tensioning wheels 743, thereby ensuring the tensioning effect of the two tensioning wheels 743 on the transmission chain 73, and utilizing the up and down movement of the telescopic rod 211 during the wave of sea water to drive the tensioning frame 742 to swing to ensure the tensioning force of the transmission chain 73. The structure is simple and reliable, and can improve the torque transmission stability between the wave-breaking float 20 and the horizontal rotor 40.

[0068] For some possible implementations, see Figure 1, wave-breaking blocks 51 are provided on the portion of the wave-breaking belt 50 between the horizontal rotor 40 and the wave-breaking float 20. The portions of each wave-breaking belt 50 between the horizontal rotor 40 and the wave-breaking float 20 together form a grid-type water-permeable structure to separate and weaken the undercurrent under the sea surface, thereby improving the seawater wave-breaking effect. Considering that the gap between adjacent wave-breaking belts 50 is wide, or the arrangement density of the wave-breaking belts 50 is low, in order to improve the wave-breaking effect, wave-breaking blocks 51 are provided on the wave-breaking belt 50. It should be noted that the wave-breaking blocks 51 provided on the wave-breaking belt 50 should not interfere with the winding of the wave-breaking belt 50 itself on the horizontal rotor 40. The wave-breaking blocks 51 can compensate for the gap between the wave-breaking belts 50 on the one hand, and prevent water waves from directly passing through the gap between adjacent wave-breaking belts 50 without being able to obtain energy reduction. On the other hand, the wave-breaking blocks 51 can form a beaded structure for each wave-breaking belt 50, thereby improving the wave-breaking effect compared with the equal-section structure.

[0069] It should be noted that the floating permeable breakwater suitable for seagrass bed ecological maintenance provided in this embodiment can be used in combination with the visual monitoring system for seagrass bed ecological restoration, and the wave-breaking float 20 and the horizontal rotor 40 are driven by the wave energy of seawater to generate a rotating driving force to drive the generator 60 to work. The electric energy generated by the generator 60 is used to supply power to the visual monitoring system, and the excess electric energy is transmitted to the land or offshore power station through the submarine cable, thereby solving the problem of offshore power supply. Since the seawater is in a fluctuating state all day and night, the continuity of power supply can be guaranteed, so that the visual monitoring system can monitor the growth and change of the seagrass bed in real time through the camera 24 hours a day, and transmit the monitoring signal to the land monitoring room through the submarine optical fiber in the form of video transmission, thereby realizing remote real-time observation of the development and change of the seagrass bed on the ground.
