Description

Technical Field

[0001] The present invention relates to the technical field of high-end marine equipment, and in particular to deep-sea aquaculture equipment in the field. Background Art

[0002] Deep sea aquaculture generally refers to aquaculture in open sea areas with a water depth of more than 20 meters. Farming . The economic benefits of developing deep-sea aquaculture are high, but the vast majority of aquaculture companies are deterred. The main reason is that the sea conditions in the open sea are harsh, and the repeated action of almost endless waves and currents in the deep sea often causes the nets to break and a large number of fish to escape. For this reason, some scholars suggest using permeable wave-breaking dikes as the infrastructure for offshore protection of aquaculture equipment, but the existing protective infrastructure on the market, which is mainly promoted by barrel-type foundation wave-breaking dikes inserted into the seabed soil layer, has the following problems: First, the vertical structure of the wave-breaking dike causes the waves reflected in front of the dike to superimpose with the incident waves to form standing waves with greater wave energy, resulting in an increase in the horizontal force of the wave-breaking dike and structural instability. Second, the barrel-type foundations are closely arranged, which is not conducive to the exchange of water flow in the aquaculture area. Third, the functions of the wave-breaking dike and the aquaculture equipment are independent of each other, and there is a problem of low integration, which increases the manufacturing cost. Fourth, silt is easy to accumulate in front of the wave-breaking dike due to poor water flow, affecting the marine ecology. More importantly, the existing deep-sea aquaculture equipment cannot simultaneously cultivate medium-sized and large-sized fish, cannot take into account different market demands and improve aquaculture efficiency, and cannot avoid the spread of viruses caused by cross-regional transportation of fish fry. Large-sized fish have strong wave resistance, but medium-sized fish have high requirements for wave currents. A new type of aquaculture equipment is urgently needed to improve deep-sea aquaculture conditions and realize the simultaneous cultivation of medium-sized and large-sized fish in deep-sea waves and rapid currents.

[0003] Comparison of patent documents list: Chinese invention patent application CN115581212A discloses an offshore aquaculture system and its design method, mentioning the installation of a wave-breaking structure outside the aquaculture area. However, this type of closely packed fixed wave-breaking cylinder inserted into the seabed inhibits the exchange of water flow in the aquaculture area, which has a significant impact on the marine environment. Since the aquaculture cages and the wave-breaking dike are arranged independently of each other, the wave-breaking cylinder is not fully utilized.

[0004] Chinese invention patent application CN117099727A discloses a wave-breaking dike and deep-sea aquaculture system, which uses a floating wave-breaking dike to form a closed aquaculture area to protect the cages in the closed aquaculture area. However, a wave-breaking dike using a mooring method often moves with the waves, making it difficult to ensure the wave-breaking effect.

[0005] Chinese utility model patent CN208023503U discloses a floating breakwater and wind energy integrated system for deep-sea aquaculture. The patent adopts a floating breakwater for wave dissipation, but it is very easy to produce a large amplitude of swing under the action of waves, making it difficult to ensure the wave dissipation effect. Summary of the invention

[0006] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a deep-sea aquaculture equipment, which realizes the structural sharing of the aquaculture equipment and the wave-breaking dike, and can carry out the synchronous aquaculture mode of medium seedlings and large seedlings at the same time, thereby improving the aquaculture efficiency.

[0009] Small floating aquaculture cages are placed in the upper water body of the aquaculture area to carry out medium-sized seedling cultivation; large-sized seedlings are cultivated in the middle and lower water layers that are not blocked by the wave-breaking dike, so as to realize the simultaneous cultivation of medium-sized seedlings and large-sized seedlings in steel pile enclosure culture.

[0010] The lower parts of the wave-breaking and flow-disturbing device and the pile foundation permeable chamber wave-breaking dam are all permeable to water, thus ensuring the normal exchange of the middle and lower water bodies in the breeding area.

[0011] The vertical height of the buoy is 0.1 times the water depth of the application sea area, and the buoy floats in the middle and upper layers of the seawater; the buoy is a quadrangular platform, and the width of its upper and lower bottom surfaces is between 0.025 and 0.05 times the average wave length of the application sea area, and the side length of the lower bottom surface along the wave movement direction is 0.05 times the average wave length of the application sea area; the distance between the upper surface of the buoy and the water surface is 1 times the average wave height of the application sea area; along the wave movement direction, the angle between the two sides of the buoy and the lower bottom surface is 65 degrees, which is used to increase the area of ​​action of the vertical force of the wave and the buoy. In the static water state, the buoy is completely submerged in water, and its overall density is consistent with the water and is in a submerged floating state.

[0012] The first connecting rod group includes two parallel vertical straight rods whose tops are fixed to the bottom of the buoy, and each vertical straight rod is connected to the bottom of the buoy through two inclined straight rods to form a triangular stable structure.

[0013] The rotating connecting rod group includes two upper and lower groups of first straight rod groups movably mounted on the vertical straight rod, the other ends of the upper and lower groups of first straight rod groups are movably mounted on the first support rod group, the end of the upper group of first straight rod groups connected to the first support rod group is fixedly connected to the second straight rod group, the other end of the second straight rod group is movably connected to the folding rod group, and the other end of the folding rod group is movably connected to the first vertical panel.

[0014] The peripheries of the first vertical panel, the second vertical panel and the third vertical panel are all wrapped with waterproof sealing rubber to ensure that the first, second and third vertical panels and the first chamber and the second chamber always maintain a tight fit when in contact to prevent water leakage from gaps.

[0016] The herringbone supporting rods are located on both sides of the second chamber.

[0017] The pile foundation permeable chamber wave-breaking dam includes a third chamber fixed on the water platform, the width of the third chamber is the same as the width of the buoy, and the length is 0.2 times the wavelength of the long-period waves in the application sea area; the third chamber is a rectangular space formed by connecting and combining a front wave-breaking panel, a rear wave-breaking panel, an upper horizontal panel, a lower horizontal panel and two side panels, the front wave-breaking panel and the rear wave-breaking panel are respectively located on the wave-facing side and the wave-back side, and there is a narrow gap between the front wave-breaking panel, the rear wave-breaking panel and the lower horizontal panel; the vertical height of the narrow gap is half of the average wave height in the application sea area.

[0018] The front wave-breaking panel is an inclined panel for guiding more waves to enter the chamber, and the rear wave-breaking panel is a vertical panel.

[0019] A movable sealing door for air entry is arranged on the upper horizontal panel close to the wave-facing side.

[0020] The submerged air outlet of the vent pipe is placed below the still water level by 1 times the average wave height of the applied sea area.

[0021] An air turbine is installed in the vent hole where the upper horizontal panel is connected to the ventilation pipe. A generator is arranged inside the air turbine. The rotation of the air turbine can drive the generator to generate electricity. The generator is connected to the light bulb arranged in the ventilation pipe near the exhaust port through a wire, which can attract more nearby plankton and flora to gather here and become dinner for the medium and large fry in the breeding equipment, thereby improving the quality of farmed fish.

[0022] The water platform uses a plurality of pile legs as a supporting frame for the deep-sea aquaculture equipment net. Steel pipe piles are arranged at the four corners of the box-type structure. The steel pipe piles support the top corners of the net to tighten the entire net to prevent fish from escaping.

[0023] The beneficial effects of the present invention are as follows: the present invention realizes the structural sharing of aquaculture equipment and wave-breaking dikes, and reduces the possibility of standing wave formation by disrupting the wave flow field through the up and down oscillating movement of the buoys, and the resonance wave-breaking dike with a pile foundation permeable chamber consumes the wave energy contained in the upper water body while ensuring the normal exchange of water flow, reducing the wave force on the deep-sea aquaculture equipment as a whole, reducing the attachment of marine organisms on the surface of the net of small floating aquaculture cages, and increasing the small-sized vortex and oxygen content of the upper water body in the aquaculture area, ensuring a higher dissolved oxygen content in the water without affecting the exchange of water flow in the middle and lower layers.

[0026] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0027] The structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no substantial technical significance.

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present invention without substantially changing the technical contents.

[0028] like Figure 1-Figure 17 As shown, the deep-sea aquaculture equipment includes a box-type structure formed by a plurality of wave-breaking devices arranged in parallel. The wave-breaking device is composed of a wave-breaking and flow-disturbing device and a pile-based permeable chamber wave-breaking dike in series. A net is attached to the pile foundation of the wave-breaking dike to form a breeding area (such as Figure 1 as shown).

[0029] like Figure 2 As shown, the wave-breaking and current-disturbing device includes a buoy 101, the vertical height of which is 0.1 times the water depth of the application sea area, and the buoy 101 is submerged in the middle and upper layers of the seawater, which greatly reduces the direct impact of waves on the buoy 101 in the horizontal direction, and reduces the risk of the buoy 101 being damaged due to excessive horizontal force. In addition, the waves are divided into upper and lower parts after passing through the buoy 101, which realizes the division of the waves in the water and forms multiple vortices, successfully disrupting the movement trajectory of water particles in the waves, causing the waves to deform. This vortex carries part of the wave energy, which not only has the effect of breaking the waves, but also provides a favorite living environment for fish. At the same time, the buoy 101 oscillates up and down due to the wave pressure and wave suction and absorbs part of the wave energy, ultimately reducing the wave energy in the water body. The cross section of the buoy 101 is a trapezoid, and the width along the y-axis direction is between 0.025 and 0.05 times the common wave wavelength in the sea area, the width of the bottom side of the trapezoidal cross section along the wave motion direction 195 is 0.05 times the common wave wavelength in the sea area, and the distance between the upper surface of the buoy 101 and the water surface is 1 times the common wave height in the application sea area. The angle between the left and right sides of the cross section of the buoy 101 and the horizontal plane is 65 degrees, which is used to increase the action area of ​​the vertical force of the wave and the buoy 101. In the static water state, the buoy 101 is completely immersed below the static water surface 194, and its overall density is consistent with the water and is in a submerged floating state.

[0030] like Figure 4 As shown, four inclined straight rods rigidly connected to the buoy 101 are respectively the first inclined straight rod 1021, the second inclined straight rod 1022, the third inclined straight rod 1023, and the fourth inclined straight rod 1024, which are used to fix the buoy 101 and the first vertical straight rod 1051 and the second vertical straight rod 1052. The first inclined straight rod 1021, the third inclined straight rod 1023, and the first vertical straight rod 1051 are on a vertical plane, and the second inclined straight rod 1022, the fourth inclined straight rod 1024, and the second vertical straight rod 1052 are on a vertical plane. The distance between the first vertical straight rod 1051 and the fourth vertical straight rod 1054 in the y-axis direction is smaller than the width of the horizontal platform 154, so that the first vertical straight rod 1051 and the fourth vertical straight rod 1054 can swing vertically without friction with the horizontal platform 154.

[0031] The buoy 101 performs a heaving motion under the action of waves, thereby driving the first inclined straight rod 1021, the second inclined straight rod 1022, the third inclined straight rod 1023, the fourth inclined straight rod 1024 and the first vertical straight rod 1051 and the fourth vertical straight rod 1054 to move. The first straight rod 118 and the third straight rod 120 originally placed horizontally in a static water state begin to rotate around the fourth rotation axis 109. One end of the first straight rod 118 and the third straight rod 120 contains a bearing hole of the fourth rotation axis 109, and the other ends of the first straight rod 118 and the third straight rod 120 placed horizontally are attached with a first U-shaped rod head 1181 and a third U-shaped rod head 1201. The first U-shaped rod head 1181 and the third U-shaped rod head 1201 contain bearing holes of U-shaped rod members. The first straight rod 118 and the third straight rod 120 placed horizontally rotate at the same time as the first rotation axis 106.

[0032] like Figure 5 As shown, at the same time, the second straight rod 119 and the fourth straight rod 121 placed horizontally in the static water state rotate synchronously around the third rotating shaft 108, and the second straight rod 119 and the fourth straight rod 121 placed horizontally have the second U-shaped rod head 1191 and the fourth U-shaped rod head 1211 attached to the other end of the second straight rod 119 and the fourth straight rod 121, and the second U-shaped rod head 1191 and the fourth U-shaped rod head 1211 contain the bearing holes of the U-shaped rod, and the second straight rod 119 and the fourth straight rod 121 placed horizontally rotate around the second rotating shaft 107. The limit nut fixed thereon plays a role in preventing the attached rod from slipping and falling off in the y direction.

[0033] like Figure 6 and Figure 7As shown, the second straight rod 119 and the fifth straight rod 122 are fixedly welded, and there is a bearing hole at the intersection of the two rods. The two straight rods rotate around the third rotating shaft 108. The other end of the fifth straight rod 122 contains a U-shaped rod, and the U-shaped rod contains a bearing hole of the fifth rotating shaft 110. The two straight rods always keep synchronous movement. The fourth straight rod 121 and the sixth straight rod 123 are fixedly welded, and there is a bearing hole at the intersection of the two rods. The two straight rods rotate around the third rotating shaft 108. The other end of the sixth straight rod 123 contains a U-shaped rod, and the U-shaped rod contains a bearing hole of the fifth rotating shaft 111. The two straight rods always keep synchronous movement. The movement of the first vertical straight rod 1051 and the fourth vertical straight rod 1054 is transmitted to the second straight rod 119 and the fifth straight rod 122, as well as the fourth straight rod 121 and the sixth straight rod 123. The second straight rod 119 and the fifth straight rod 122 are a component; the fourth straight rod 121 and the sixth straight rod 123 are a component, and the two components rotate around the third rotating shaft 108 at the same time, and are further transmitted to the fifth rotating shaft 110 and the sixth rotating shaft 111, and then the movement is transmitted to the first folding rod 129 and the second folding rod 130, and the movement is transmitted to the first U-shaped connector 131 and the second U-shaped connector 132 through the seventh rotating shaft 112 and the eighth rotating shaft 113. The first U-shaped connector 131 and the second U-shaped connector 132 contain bearing holes, and then the movement continues to be transmitted to the first vertical panel 135. The fifth straight rod 122 and the sixth straight rod 123 are connected to the first folding rod 129 and the second folding rod 130 through their own U-shaped rods and bearing holes, which can guide the first vertical panel 135, the second vertical panel 136, and the third vertical panel 137 to move horizontally.

[0034] like Figure 8 As shown, the first vertical panel 135 drives the first horizontal straight rod 159, the second horizontal straight rod 160, the third horizontal straight rod 161, and the fourth horizontal straight rod 162 to push the second vertical panel 136 to move horizontally. The first watertight rubber ring 138 and the second watertight rubber ring 139 are respectively wrapped around the four edges of the first vertical panel 135 and the second vertical panel 136 to ensure that the vertical panel and the first chamber 141 always keep a close fit when in contact to prevent water leakage from the gap. The first vertical panel 135 also acts as a vertical panel movement range limiter. Through the third U-shaped connector 133 and the ninth rotating shaft 114, the third U-shaped connector 133 contains the bearing hole of the ninth rotating shaft 114. The third U-shaped connector 133 is above the middle distance between the first U-shaped connector 131 and the second U-shaped connector 132, and also has a bearing hole.

[0035] like Fig. 9As shown, the motion is transmitted to the seventh straight rod 124 and to the third bearing 149. The third bearing 149 and the seventh straight rod 124 are fixedly welded. The seventh straight rod 124 rotates around the eleventh rotating shaft 116 through the third bearing 149, driving the tenth straight rod 127 and the eleventh straight rod 128 to rotate around the ninth rotating shaft 114 and the tenth rotating shaft 115 respectively. Both ends of the tenth straight rod 127 and the eleventh straight rod 128 have bearing holes. The first bearing 147 is fixedly welded to the first support rod 150 and the second support rod 151. The second bearing 148 is fixedly welded to the third support rod 152 and the fourth support rod 153. The first support rod 150, the second support rod 151, the third support rod 152, and the fourth support rod 153 are fixedly welded to the horizontal platform 154.

[0036] The vertical panel movement range limiter prevents the first vertical panel 135 and the third vertical panel 137 from moving too much beyond the movement range of the first chamber 141 and the second chamber 142, while increasing the stability of the entire associated system.

[0037] The side and top of the first chamber 141 close to the back-wave side 193 are respectively connected to the first water pipe 155 and the second water pipe 156, and the ends of the two water pipes are respectively arranged on the wave-facing side 192 and the back-wave side 193 of the pile foundation permeable chamber wave-breaking dam; a ventilation pipe 186 connected to the interior is arranged on the top of the back-wave side 193 of the pile foundation permeable chamber wave-breaking dam, and the other end of the ventilation pipe 186 is bent downward, and the end is located on the back-wave side 193 outside the pile foundation permeable chamber wave-breaking dam.

[0038] In addition, the first vertical panel 135 is fixedly connected with the third vertical panel 137 through the eighth straight rod 125 and the ninth straight rod 126, and the third watertight rubber ring 140 is wrapped around the four sides of the third vertical panel 137. With the synchronous movement of the first vertical panel 135, the second vertical panel 136, and the third vertical panel 137, the seawater in the first chamber 141 is sucked and ejected through the first water flow exchange hole 144, the second water flow exchange hole 145, and the water flow exchange port 146. The first water flow exchange hole 144 is externally connected to the first water pipe 155, and the second water flow exchange hole 145 is externally connected to the second water pipe 156. The diameters of the first water pipe 155 and the second water pipe 156 are between 8 cm and 16 cm. When the second vertical panel 136 moves to the second water flow exchange hole 145 of the first chamber 141, the third vertical panel 137 moves to the outermost end of the second chamber 142 in the x direction, and is about to leave the second chamber 142.

[0039] The outlet of the end of the first water pipe 155 is fixedly welded to the rear wave-breaking board 164 of the wave-breaking dam through the first fixing piece 157 and is vertically upward. The outlet of the second water pipe 156 is placed in the water body on the wave-facing side 192 of the front wave-breaking board 163 of the wave-breaking dam through the second fixing piece 158 without leaking out of the water.

[0040] The areas of the first vertical panel 135 and the second vertical panel 136 are equivalent to the cross-sectional area of ​​the first chamber 141 , and the area of ​​the third vertical panel 137 is equivalent to the cross-sectional area of ​​the second chamber 142 .

[0041] When the crest of the short-period moderate wave passes through the buoy 101, the vertical upward wave force on the buoy 101 reaches the minimum value, which is insufficient to support the upward movement of the buoy 101, and the buoy 101 starts to move downward from the highest position. At this time, the buoy 101 drives the first vertical straight rod 1051 and the fourth vertical straight rod 1054 to move downward, and transmits the mechanical force to the first straight rod 118, the second straight rod 119, the third straight rod 120, the fourth straight rod 121, the fifth straight rod 122, and the sixth straight rod 123 in sequence, and then transmits it to the first folding rod 129 and the second folding rod 130 at the same time, driving the reciprocating horizontal movement of the first vertical panel 135, the second vertical panel 136, and the third vertical panel 137 to squeeze the first chamber 141, The water in the second chamber 142 is expanded to form a jet and a suction flow. The first water pipe 155 is close to the net 190 of the small floating aquaculture cage 2 and the rear wave plate 164 of the wave breakwater, and the water in the first cavity 141 is sprayed to the vicinity of the net 190 of the small floating aquaculture cage 2, increasing the flow rate near the net 190, and washing away the larvae of marine attachments through continuous jets and suction flows, and not giving the larvae of marine attachments the opportunity to implant for a certain period of time, thereby preventing marine attachments from landing on the aquaculture equipment. At the same time, the jet and suction flow accelerate the formation of small-sized vortices, which is beneficial to the growth of fish.

[0042] In addition, when the buoy 101 moves to the lowest part of the movement range, the second vertical panel 136 moves to the second water flow exchange hole 145 of the first chamber 141, and the second water flow exchange hole 145 is connected to the second water pipe 156. The water ejected from the second water pipe 156 impacts the water body in front of the wave-breaking dike front wave-breaking panel 163. According to Bernoulli's formulas (1) and (2), the jet increases the fluid velocity at the wave-breaking dike front wave-breaking panel 163, thereby reducing the horizontal wave force borne by the front wave-breaking panel 163 and the whole wave-breaking dike structure, and improving the safety of the first leg 171, the second leg 172, the third leg 173, and the fourth leg 174. At the same time, the volume of the second chamber 142 increases, and the external water is sucked into the second chamber 142 through the water flow exchange port 146, disrupting the original predetermined movement trajectory of the wave water particles.

[0043] When the trough of the short-period moderate wave passes through the buoy 101, the vertical upward wave force on the buoy 101 reaches the maximum value. Under the action of the wave, the buoy 101 starts to move upward from the lowest position, driving the first vertical straight rod 1051 and the fourth vertical straight rod 1054 to move upward, and transmits the mechanical force to the first straight rod 118, the second straight rod 119, the third straight rod 120, the fourth straight rod 121, the fifth straight rod 122, and the sixth straight rod 123 in sequence, and then transmits it to the first folding rod 129 and the second folding rod 130, driving the first vertical panel 1 35 and the second vertical panel 136 and the third vertical panel 137 are translated toward the wave-facing side 192, and the volume of the first chamber 141 becomes larger. The water near the net 190 of the small-sized aquaculture cage 2 is sucked into the first chamber 141 through the second water pipe 156 and the first water pipe 155, and the liquid near the net 190 of the aquaculture platform is sucked in. The liquid around the sucked liquid fills the gap by itself, and the larvae of the marine attachments are drawn into the first chamber 141. If they are not given the opportunity to implant within a certain period of time, the larvae will die, thereby preventing the marine attachments from landing on the net. The water sucked in the second water pipe 156 will generate more vortices in the water body on the wave-facing side 192 of the front wave-blocking panel 163, reduce the wave force on the front wave-blocking panel 163, and increase the safety of the first leg 171, the second leg 172, the third leg 173, and the fourth leg 174. At the same time, the volume of the second chamber 142 becomes smaller, and the water in the second chamber 142 is ejected through the water flow exchange port 146, thereby disrupting the originally predetermined movement trajectory of the water particles.

[0044] The inclined rod 189 further reinforces the first pile leg 171, the second pile leg 172, the third pile leg 173, and the fourth pile leg 174. The second vertical straight rod 1052 and the third vertical straight rod 1053 are fixedly welded to the horizontal platform 154, and the second vertical straight rod 1052 and the third vertical straight rod 1053 and the horizontal platform 154 are welded together through the fifth inclined straight rod 103 and the sixth inclined straight rod 104 respectively. The cross rod 134 connects the second vertical straight rod 1052 and the third vertical straight rod 1053.

[0045] Bernoulli equation (1) Among them, ρ is the density of water, g is the acceleration due to gravity, z1 and z2 are the vertical heights, u 1 is the horizontal velocity of the water particle on the front and rear panels of the chamber breakwater acting on the wave, u 2 is the horizontal velocity of the water particles that bounce back after the wave hits the front and rear panels of the chamber breakwater, p 1 is the point pressure of the wave acting on the front and rear panels of the chamber breakwater, p 2 is the point pressure where the wave rebounds after hitting the front and rear panels of the chamber breakwater, C 1. C2 is a constant. Since the vertical heights of the water particles acting on the front and rear panels of the chamber breakwater and rebounding after hitting the breakwater are equal, the Bernoulli equation becomes: (2) If you want the front and rear panels of the chamber breakwater to bear less wave force, then p 1 needs to be small. According to Bernoulli's formula (1), u 1 needs to be enlarged, so the present invention starts from increasing the water particle velocity at the front and rear panels of the chamber wave-breaking dike. When the wave hits, the fluid in the first chamber is driven to move in the form of jet or suction to disrupt the wave motion pattern at the front panel of the chamber wave-breaking dike, so as to achieve the effect of reducing the wave force. At the same time, the jet and suction also dissipate part of the wave energy, thereby improving the wave-breaking effect.

[0046] The conservation formula of the squeezed liquid flow in the first chamber 141 and the second chamber 142 is: A1×v1=A2×v2 (3) A1 is the cross-sectional area of ​​the jet outlet hole, v1 is the jet outlet water velocity, A2 is the area of ​​the first vertical panel, the second vertical panel, and the third vertical panel, and v2 is the horizontal movement speed of the first vertical panel, the second vertical panel, and the third vertical panel.

[0047] like Fig.10 , Fig.11 As shown, the operating mechanism of the buoy pushing the vertical panels: The formula for pressure P at any point in water is: (4) ρ is the density of water, g is the acceleration of gravity, H is the wave height, h is the water depth, and the expression of the wave number k is as follows: k=2π / L, L is the wave length, z is the vertical coordinate value, x is the coordinate value of the wave travel direction, ω is the wave circular frequency, ω=2π / T, T is the wave period, and t is the wave running time.

[0048] The formula for the vertical wave force Fz of the buoy 101 is: (5) like Fig.10 , Fig.11 As shown, the force on each surface of the buoy is specified to be negative vertically downward, b is the width of the buoy in the y-axis direction, l 1、 l 2、 l 3、 l4 represents the length of the four different sides of the buoy section, P1, P2, P3, and P4 are the sum of the point pressures of the four sides. Only the cross-sectional force analysis is considered, and the side force of the buoy parallel to the x-axis is not considered. ɵ is the angle between the point pressure and the x-axis. The angle of the present invention is 25 degrees. The vertical wave pressure Fz changes with the waves. When the vertical wave pressure on the buoy is greater than the damping force of the first vertical panel 135, the second vertical panel 136, and the third vertical panel 137 and the chamber water pressure, the first chamber 141 and the second chamber 142 begin to generate jets and suctions.

[0049] Mechanical analysis of the vertical panel movement driven by the buoy: Fz×d1≥Fx×d2 (6) d1 is the power arm that drives the first vertical straight rod 1051 and the fourth vertical straight rod 1054 to rotate around the fourth rotating shaft 109 simultaneously due to the movement of the buoy, Fx is the damping force of the three vertical panels to overcome friction and discharge the liquid in the chamber, and d2 is the resistance arm from the first vertical panel 135 to the fourth rotating shaft 109.

[0050] A series of attachment structures associated with the buoy 101 act as a damper for the movement of the buoy, playing the role of a spring buffer. The vertical panel movement range limiter in the attachment structure can limit the movement range of the buoy 101, so that the buoy 101 suspended in the upper layer of the seawater still maintains good stability under the action of waves. In addition, the wave-breaking and turbulent device has a good effect of gathering and sheltering fish, and can also be used as a floating fish reef to increase fishery resources and improve the marine environment.

[0051] like Figure 12-Figure 15As shown, the pile foundation permeable chamber wave-breaking dike includes a front wave-breaking panel 163, a rear wave-breaking panel 164, an upper horizontal panel 165, a first side panel 166, a second side panel 167, a lower horizontal panel 168, a first leg 171, a second leg 172, a third leg 173, a fourth leg 174, a vent 175, an air turbine 176, a support frame 181, a limiter 182, a sealing door 183, a hinge 184, a spring 185, a vent pipe 186, and a diagonal rod 189. The width of the pile foundation permeable chamber wave breakwater along the y-axis direction is the same as that of the buoy 101, the front wave-breaking panel 163 is an inclined panel for guiding more waves into the chamber, the rear wave-breaking panel 164 is a vertical panel, and the width of the lower horizontal panel 168 along the x-axis direction is 0.2 times the wavelength of medium and long period waves commonly seen in the sea area. In addition, the water platform 154 is flush with the lower horizontal panel 168, and the two structures are fixed and welded. In addition, the front wave-breaking panel 163, the rear wave-breaking panel 164, the upper horizontal panel 165, the lower horizontal panel 168, the first leg 171, the second leg 172, the third leg 173, the fourth leg 174, and the diagonal rod 189 are all made of hollow steel plates and are wrapped with concrete inside. The space formed by the combination of the front wave-breaking panel 163, the rear wave-breaking panel 164 and the upper horizontal panel 165, the first side panel 166, the second side panel 167, and the lower horizontal panel 168 forms a third chamber 143. Seawater flows through the first parallel narrow slits 169 and the second parallel narrow slits 170 of the third chamber 143 successively. The vertical height of the two parallel narrow slits is half of the common wave height in the application sea area, and the width along the y-axis is slightly smaller than the width of the third chamber 143, and the difference between the two is the thickness of the first side panel 166 and the second side panel 167.

[0052] The first chamber 141 , the second chamber 142 , and the third chamber 143 all have two side panels, which are prior art and will not be described in detail.

[0053] The operating mechanism of bubble wave elimination: Surface wave water particle velocity U x for: (7) Calculate the horizontal flow velocity V generated by the vent hole to remove bubbles based on the exhaust volume per second h For (such as Fig.16 shown): (8) Where H is the wave height, h is the water depth, D is the submerged depth of the snorkel outlet, and P air is the atmospheric pressure, Q is the change in the gas inside the chamber, which can be calculated by the up and down movement of the waves in the chamber, and g is the acceleration due to gravity.

[0054] As the waves rise and fall in the closed chamber, the air in the third chamber 143 is continuously compressed and expanded. When the crest of the short-period moderate wave enters the third chamber 143 after passing through the wave-breaking and turbulent device, the liquid level inside the third chamber 143 rises, the original gas space inside the chamber is occupied by the liquid, the gas is compressed, and the atmospheric pressure inside the third chamber 143 is greater than that outside. Under the action of atmospheric pressure and spring 185, the sealing door 183 rotates upward around the hinge 184 to the stopper 182 and stops moving. At this time, the air in the chamber stops being discharged from the vent 191, and the inside of the third chamber 143 continues to be squeezed by the liquid. At the same time, the air is discharged through the vent 175 and the vent pipe 186, and bubbles begin to spray out from the outlet of the vent pipe 186 at the water inlet end, which is transmitted into the water body of the aquaculture equipment, increasing the oxygen content in the surface aquaculture water body for high-density aquaculture fish and more phytoplankton to absorb and utilize at night. The submerged air outlet of the vent pipe 186 is placed at a height of 1 times the common wave height in the applied sea area below the still water level.

[0055] When the crest of a long-term severe wave enters the third chamber 143, the wave movement in the third chamber 143 is stronger, which compresses the original air volume in the chamber, causing more bubbles to be discharged from the vent pipe 186. The larger bubble bursts and causes greater disturbance to the waves. Referring to formulas (7) and (8), when V h Greater than the surface wave water particle velocity u x When the wave is attenuated effectively, the effect of energy dissipation by bubble bursting is achieved. In addition to entering the third chamber 143, the remaining wave energy bypasses the lower horizontal panel and rushes to the aquaculture waters, ensuring the normal water exchange of benthic fish.

[0056] When the trough reaches the third chamber 143, the liquid level in the third chamber 143 drops, the air in the chamber begins to expand, the atmospheric pressure in the third chamber 143 is lower than that outside, the pulling force of the spring 185 is lower than the atmospheric pressure difference inside and outside the third chamber 143, the sealing door 183 moves downward and opens automatically, and air enters.

[0057] When the trough of the short-period moderate wave passes through the buoy 101 and continues to move forward, it enters the interior of the third chamber 143 from the first parallel narrow slit 169, and the liquid level in the third chamber 143 begins to drop. Under the action of atmospheric pressure, the sealing door 183 is in an open state, air enters the chamber, and the vent pipe 186 stops jetting. At the same time, the wave forms a plurality of large vortices between the front wave-breaking panel 163 and the rear wave-breaking panel 164 and Helmholtz cavity resonance occurs, dissipating most of the wave energy, and only a small part of the wave energy in the cavity flows out from the second parallel narrow slit 170 of the third chamber 143 in the form of flow.

[0058] Under the action of waves, the liquid surface in the third chamber 143 vibrates up and down, continuously compressing the air in the chamber to form a reciprocating airflow. The airflow continuously blows the air turbine 176 through the vent hole 175 above the chamber. The air turbine 176 rotates to drive the generator to generate electricity. The generator is placed inside the sleeve 178. This is a prior art and is not specifically described in the present invention. Fig.13 shown.

[0059] The upper bracket 177 and the lower bracket 180 fix the twelfth rotating shaft 117 in the vent hole 175. The fan blade 179 starts to rotate under the action of the airflow, further driving the sleeve 178 to rotate, and then driving the generator. The electric energy generated by the generator is transmitted to the light bulb 188 through the wire 187. Fig.14 When night comes, the additional oxygen and the light bulb 188 attached to the exhaust port of the vent pipe 186 can also attract more nearby phytoplankton to gather here, becoming the dinner of the medium and large fry in the breeding equipment, thereby improving the quality of the farmed fish.

[0060] In order to ensure that the pile foundation permeable chamber wave-breaking dike has a better wave-breaking and oxygen-increasing effect, the draft of the entire pile foundation permeable chamber wave-breaking dike accounts for 0.2 to 0.35 times the entire water depth. In addition, a small floating aquaculture cage 2 is placed in the upper water body in the deep-sea aquaculture equipment to carry out medium seedling cultivation, while the middle and lower water flow is not blocked by the wave-breaking dike and large seedlings are continued to be cultivated. The first pile leg 171 and the second pile leg 172 used to fix the wave-breaking dike can also be used as a supporting frame for the deep-sea aquaculture equipment net 190. The first steel pipe pile 301, the second steel pipe pile 302, the third steel pipe pile 303, and the fourth steel pipe pile 304 support the top angle of the net 190 to tighten the entire net to prevent fish from escaping.

[0061] like Figure 1 , Figure 2 As shown, the deep sea aquaculture environment is relatively harsh. The steel pipe pile enclosure aquaculture equipment mentioned in the present invention is to drive the first leg 171, the second leg 172, the third leg 173, and the fourth leg 174 into the seabed 196, and the net is laid along the first leg 171 and the second leg 172. The net is a tortoise shell net, which can withstand the impact of water with a large flow rate. The aquaculture area of ​​the entire aquaculture equipment ranges from 10 acres to 100 acres. Small floating aquaculture cages are placed in the aquaculture equipment to carry out medium seedling cultivation, and the middle and lower water flow is not blocked by the wave-breaking dike, so that large seedlings can be relayed and cultured at the same time, realizing the synchronous culture of medium and large seedlings in steel pile enclosure aquaculture.

[0062] The lower part of the wave-breaking and flow-disturbing device and the pile-foundation permeable chamber wave-breaking dam is permeable, ensuring the normal exchange of water bodies in the middle and lower layers of the breeding area.

[0063] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art on the basis of the technical solution of the present invention without creative work are still within the scope of protection of the present invention.
