Technical Field

[0001] The present invention relates to the field of marine aquaculture technology, and in particular to marine aquaculture equipment and offshore wind power systems. Background Art

[0002] Marine ranching refers to the planned and purposeful stocking at sea of ​​artificially released economic marine organisms by means of large-scale fishery facilities and systematic management and by utilizing the marine ecological environment within a certain sea area.

[0003] In existing marine ranches, fish, shrimp and other farmed fish are placed in cages for breeding. Due to the limited area of ​​offshore aquaculture, many companies have turned their attention to deep sea areas to carry out deep sea aquaculture.

[0004] In the prior art, the net cages are usually placed semi-submerged in the sea. When facing a typhoon at sea, the net cages located in the sea have a wide wave-facing surface and are easily broken by wind and waves, resulting in fish escaping, thereby causing serious economic losses. Summary of the invention

[0005] In view of this, the present invention provides an offshore aquaculture equipment and an offshore wind power system to solve the problem in the prior art that when a semi-submerged cage is placed in the sea, it has a wide wave-facing surface and is easily broken by wind and waves when facing an offshore typhoon.

[0006] In a first aspect, the present invention provides an offshore aquaculture equipment, including a mounting frame, a cage and a lifting assembly, wherein the interior of the mounting frame is a accommodating cavity with an opening at the top, the bottom of the mounting frame is suitable for being set in water with the top exposed above the water surface, the cage is movably arranged in the accommodating cavity, one end of the lifting assembly is fixed to the mounting frame, and the other end is connected to the cage, and the lifting assembly has a first state of driving the top of the cage to sink into the sea, and a second state of driving the cage to float to the surface of the sea.

[0007] Beneficial effect: The present invention is provided with a lifting component. When a typhoon comes at sea, the lifting component drives the cage to be in the first state where the top is sunk into the sea. When the cage sinks to a certain depth in the sea, the top of the cage is above the average sea level and exceeds the maximum wave height, which can reduce the impact of wind and waves on the cage and avoid damage to the cage. After the typhoon is over, the lifting component drives the cage to return to its original position. The lifting component lifts the cage to the second state where it floats to the surface for easy maintenance of the cage. It has the advantages of simple structure and convenient operation.

[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0043] Combine the following Figures 1 to 4 , describing an embodiment of the present invention.

[0044] According to an embodiment of the present invention, on the one hand, Figures 1 to 3As shown, there is provided an offshore aquaculture equipment 100, comprising a mounting frame 1, a net cage 2 and a lifting assembly 3. The interior of the mounting frame 1 is a containing cavity with an opening on the top. The bottom of the mounting frame 1 is suitable for being set in water with the top exposed above the water surface. The net cage 2 is movably set in the containing cavity. One end of the lifting assembly 3 is fixed on the mounting frame 1 and the other end is connected to the net cage 2. The lifting assembly 3 has a first state of driving the top of the net cage 2 to sink into the sea, and a second state of driving the net cage 2 to float to the surface of the sea.

[0045] Specifically, in this embodiment, the bottom of the mounting frame 1 is set in the seawater, the top opening is higher than the sea level 10, and the cage 2 is set inside the mounting frame 1. The cage 2 is used to breed aquatic animals, such as fish, shrimp, shellfish, etc. Figure 1 As shown, during normal breeding, the net cage 2 is entirely located above the seawater below the sea level 10 under the control of the lifting assembly 3; Figure 2 As shown, when a typhoon comes, the net cage 2 is lowered as a whole to a certain depth below the sea level 10 through the lifting component 3. When the net cage 2 sinks to the predetermined depth, that is, the top of the net cage 2 is more than the maximum wave height from the average sea level 10, and the bottom plane of the net cage 2 is more than 5m away from the seabed plane, the adjustment of the lifting component 3 is stopped. At this time, the net cage 2 has reached the predetermined required position and can avoid the impact of wind and waves in the typhoon.

[0046] In this embodiment, during the breeding period of the cage 2 under normal working conditions, Figure 1 As shown, the net cage 2 is located above the seawater below the sea level 10, and the organisms in the net cage 2 are fed with feed regularly at intervals every day through a remotely controlled automatic feeding device.

[0047] In this embodiment, the calculation formula for the height H of the designed cage 2 is as follows:

[0048] H=H w -(H0+5m)

[0049] Among them, H w is the water depth and H0 is the maximum wave height in the sea area.

[0050] For example, according to the maximum wave protection requirement of 10m, the maximum depth of cage 2 is H = H w -(10+5), for example, at a water depth of 45m, a cage 2 with a maximum height of 30m is set.

[0051] The present invention is provided with a lifting component 3. When a typhoon comes at sea, the lifting component 3 drives the net cage 2 to be in a first state where the top is sunk into the sea. When the net cage 2 sinks to a certain depth in the sea, the top of the net cage 2 is 10 meters away from the average sea level and exceeds the maximum wave height, which can reduce the impact of wind and waves on the net cage 2 and avoid damage to the net cage 2. After the typhoon ends, the lifting component 3 drives the net cage 2 to return to its original position. The lifting component 3 lifts the net cage 2 to the second state where it floats to the surface of the water, which is convenient for maintenance of the net cage 2. The invention has the advantages of simple structure and convenient operation.

[0052] In one embodiment, Figure 1 As shown, the lifting assembly 3 includes a first driver 301 and a first pull rope 302. The two first drivers 301 are respectively installed on both sides of the opening. One end of the first pull rope 302 is connected to the side of the net box 2, and the other end is movably connected to the first driver 301.

[0053] Specifically, in this embodiment, the first driver 301 is not specifically limited. In this embodiment, the first driver 301 is a winch, which is installed on the inner side of the opening of the mounting frame 1. One end of the first pull rope 302 is set on the net box 2, and the other end is set on the winch. The first pull rope 302 is tightened by the operation of the winch, thereby realizing the first state of sinking the top of the net box 2 to below the sea level 10 and the second state of lifting the net box 2 to above the sea level 10.

[0054] The present invention controls the retraction and extension of the first pull rope 302 through the first driver 301 to realize the conversion of the cage 2 between the first state and the second state, has the advantages of simple structure and convenient operation, and ensures the economic benefits of the breeding cage 2.

[0055] In one embodiment, Figure 1 As shown, the lifting assembly 3 further includes a first platform 303 . Two first platforms 303 are respectively mounted on two opposite inner walls of the mounting frame 1 . The first driver 301 is disposed on the first platform 303 .

[0056] Specifically, in this embodiment, the first platform 303 is arranged on the inner walls on both sides of the mounting frame 1 and extends toward the center of the opening. The first driver 301 is installed on the first platform 303. The inward extension length of the first platform 303 is not greater than the distance between the side wall of the cage 2 and the inner wall of the mounting frame 1.

[0057] In one embodiment, Figure 1 As shown, the lifting assembly 3 also includes a vertical pole 304 and a connecting ring 305. The two vertical poles 304 are symmetrically and vertically arranged on both sides of the net box 2. The connecting ring 305 is movably mounted on the vertical pole 304. The end of the first pull rope 302 away from the first driver 301 is connected to the connecting ring 305.

[0058] Specifically, in this embodiment, two vertical poles 304 are symmetrically arranged vertically on both sides of the net cage 2, and a connecting ring 305 is sleeved on the vertical pole 304 on each side, and the first pull rope 302 is connected to the connecting ring 305. In daily farming, the first pull rope 302 is in a taut state under the weight of the net cage 2. At this time, the connecting ring 305 connected to the first pull rope 302 is located at the top of the vertical pole 304, which plays a pulling role on the vertical pole 304; Figure 3 As shown, after the cage 2 has been in operation for a certain period of time, due to the attachment of marine organisms and the influence of various environmental factors, when the cage 2 needs to be maintained, such as cleaning the net, repairing damaged nets, checking problems, etc., the first driver 301 tightens the first pull rope 302, and the tension and friction of the connecting ring 305 can lift the top of the cage 2 to a position higher than the first driver 301, and also lift the bottom of the cage 2 to above the sea level 10, at which time the first pull rope 302 is in a horizontal state.

[0059] The present invention movably sets the connecting ring 305 on the vertical pole 304. When the first pull rope 302 is tightened, the connecting ring 305 slides on the vertical pole 304. The tension and friction of the connecting ring 305 can lift the top of the net box 2 to a position higher than the first driver 301, making it convenient for staff to maintain the net box 2.

[0060] In one embodiment, Figure 1 As shown, the lifting assembly 3 also includes a second driver 306, a fixed pulley 307 and a second pull rope 308. The two second drivers 306 are respectively installed on both sides of the opening, and the two rising fixed pulleys 307 are respectively installed at the bottom of the mounting frame 1. One end of the second pull rope 308 is fixedly connected to the bottom of the vertical pole 304, and the other end is movably connected to the second driver 306. The second pull rope 308 is movably installed on the fixed pulley 307.

[0061] Specifically, in this embodiment, brackets are respectively installed at the bottom positions of the inner walls on both sides of the mounting frame 1, and the fixed pulley 307 is rotatably installed on the brackets. On the inner wall of the mounting frame 1, a plurality of pull rings are installed at positions between the opening and the brackets. The second driver 306 is a winch, which is installed at the top opening of the mounting frame 1. One end of the second pull rope 308 is connected to the bottom of the vertical pole 304, and the other end is installed on the winch. The second pull rope 308 is passed through the pull ring and is wound around the fixed pulley 307.

[0062] In this embodiment, when the net box 2 is sunk, the first driver loosens the first pull rope 302, and the second driver 306 tightens the second pull rope 308, and the net box 2 moves downward under the joint action of the first pull rope 302 and the second pull rope 308. After the net box 2 sinks to a suitable position, the first pull rope 302 and the second pull rope 308 keep the net box 2 in a tensioned state, so as to control the position of the net box 2 and prevent it from swinging; on the contrary, when the net box 2 is lifted, the first driver tightens the first pull rope 302, and the second driver 306 loosens the second pull rope 308, and the net box 2 moves upward under the joint action of the first pull rope 302 and the second pull rope 308.

[0063] The present invention connects the second pull rope 308 to the bottom of the net box 2. When the net box 2 is moving, the first pull rope 302 cooperates with the second pull rope 308 to move the net box 2 along a vertical trajectory, thereby reducing shaking of the net box 2 during movement.

[0064] In one embodiment, Figure 1 As shown, the lifting assembly 3 further includes a second platform 309 , and two second platforms 309 are respectively installed on both sides of the opening, the first platform 303 is located below the second platform 309 , and the second driver 306 is arranged on the second platform 309 .

[0065] Specifically, in this embodiment, the second platform 309 is arranged at the top opening of the mounting frame 1 and extends toward the center of the opening. The second driver 306 is installed on the second platform 309. The inward extension length of the second platform 309 is not greater than the distance between the side wall of the cage 2 and the inner wall of the mounting frame 1.

[0066] In this embodiment, the height of the first platform 303 is not less than half of the height of the cage 2 maintained at 10 above sea level and not less than the maximum wave height; the height of the second platform 309 is not less than the height of the cage 2 maintained at 10 above sea level.

[0067] The second platform 309 of the present invention is provided to facilitate the staff to maintain the net box 2 on the second platform 309 .

[0068] In one embodiment, Figure 1 As shown, the offshore farming equipment 100 further includes a buffer member 4 , and a plurality of buffer members 4 are arranged on the vertical pole 304 , and are located on a side away from the cage 2 .

[0069] Specifically, in this embodiment, the buffer member 4 is not specifically limited. For example, in this embodiment, the buffer member 4 is a spring, and a plurality of springs are arranged on the side of the vertical rod 304 facing the inner wall of the mounting frame 1 .

[0070] The present invention provides a buffer 4 on the vertical pole 304. When the net box 2 is shaken by wind and waves during the ascending or descending movement, the buffer 4 between the vertical pole 304 and the mounting frame 1 can absorb part of the impact force of the net box 2 on the mounting frame 1, thereby avoiding damage to the net box 2 due to collision.

[0071] In one embodiment, Figure 1 As shown, the offshore aquaculture equipment 100 also includes an adjustment component 5, which includes a tightener 501, a cable 502 and an adjustment body 503. The two tighteners 501 are respectively arranged on the top of the cage 2, and one end of the two cables 502 is respectively connected to the tighteners 501. The adjustment body 503 is movably arranged inside the cage 2, and the end of the cable 502 away from the tightener 501 is connected to the adjustment body 503.

[0072] Specifically, in this embodiment, two tighteners 501 are respectively installed at the top of the net box 2, located on both sides close to the first platform 303, and the adjusting body 503 is slidably arranged on the slide rail at the bottom of the net box 2. Both ends of the adjusting body 503 are respectively connected to the tighteners 501 through a cable 502. Detectors are provided on both sides of the net box 2, and the detectors are connected to the adjusting body 503 by signal. The detectors are not specifically limited in this embodiment. For example, the detector in this embodiment is a rangefinder, which is used to detect the offset distance between the net box 2 and the mounting frame 1. During the sinking process of the net box 2, when the net box 2 is subjected to unbalanced force and tilts laterally, the rangefinder detects that the distance between the side of the net box 2 and the mounting frame 1 is offset, and transmits a signal to the adjusting body 503, and the adjusting component 5 takes effect. If the net box 2 tilts to the right, the driver in the adjusting body 503 applies a force toward the left to the net box 2, and the adjusting body 503 slides to the right under the coordinated adjustment of the two cables 502, and the tightener 501 on the right tightens the right cable 502, and the left cable 502 is pulled out from the left tightener 501 under the tension of the adjusting body 503 to achieve the adjustment balance of the net box 2. When tilting in the opposite direction, the balance adjustment of the net box 2 is performed in the same way. In this embodiment, the driver is not specifically limited. For example, the driver includes a motor and a rotating wheel, the rotating wheel is rotatably installed on the slide rail, and the motor is installed in the adjusting body 503. When the motor drives the rotating wheel to rotate, the rotating wheel exerts a force opposite to the direction of movement on the guide rail under the action of friction.

[0073] The present invention arranges an adjustment component 5 in the net box 2. When the net box 2 is subjected to unbalanced force and tilts laterally during movement, the adjustment body 503 slides under the coordinated adjustment of the two cables 502 to achieve the adjustment balance of the net box 2.

[0074] In one embodiment, Figure 1As shown, the net box 2 includes a top frame 201, a bottom frame 202, columns 203, a net and a ballast buoy 204, four columns 203 are vertically connected between the top frame 201 and the bottom frame 202, the top frame 201, the bottom frame 202 and the columns 203 form a frame structure, the net is set on the frame structure, and the ballast buoy 204 is set at the bottom of the bottom frame 202.

[0075] Specifically, the net box 2 is not specifically limited in this embodiment. For example, in this embodiment, the top frame 201 and the bottom frame 202 are rectangular frames, and four columns 203 are vertically arranged between the top frame 201 and the bottom frame 202. The top frame 201, the bottom frame 202 and the columns 203 form a cubic frame structure. In some other embodiments, the net box 2 can also be a polygonal or circular space structure.

[0076] In this embodiment, the net is not specifically limited. For example, in this embodiment, the net is a fully enclosed type, and the material is alloy metal or ultra-high molecular polyethylene material. The net is arranged on the frame structure, and the frame is surrounded into a closed space. A plurality of ballast buoys 204 are arranged at the bottom of the bottom frame 202. When a typhoon comes, the ballast buoys 204 are filled with water, and the net box 2 gradually and steadily sinks downward; when the net box 2 needs to be maintained, the ballast buoys 204 are inflated, and the ballast water is discharged. The net box 2 floats steadily to the sea level 10 by buoyancy. At this time, the first pull rope 302 is connected to the vertical pole 304 through the connecting ring 305, and is in a horizontal state. The height is about more than half of the height of the net box 2, which effectively prevents the net box 2 from swaying under the action of waves, thereby ensuring the safety of the structure of the net box 2 and the safe operation of the maintenance personnel.

[0077] In this embodiment, both sides of the top frame 201 and the bottom frame 202 extend outward from the column 203 , and the outwardly extending ends are connected to the pole 304 , so that the pole 304 and the column 203 have a certain distance, so that the connecting ring 305 can move on the pole 304 .

[0078] The present invention arranges a ballast buoy 204 at the bottom of the bottom frame 202 , and adjusts the buoyancy of the ballast buoy 204 on the net cage 2 by filling or draining water in the ballast buoy 204 , thereby achieving the floating and sinking of the net cage 2 .

[0079] In one embodiment, Figure 1 As shown, the offshore aquaculture equipment 100 further includes pile foundations 6 and guide cylinders 7 . A plurality of pile foundations 6 are suitable for being arranged on the bottom of the water. A plurality of guide cylinders 7 are installed at the bottom of the mounting frame 1 , and the pile foundations 6 are installed in the guide cylinders 7 .

[0080] Specifically, in this embodiment, the number of pile foundations 6 is not specifically limited. In this embodiment, a total of four pile foundations 6 are provided. The pile foundations 6 are steel pipe piles. Four guide cylinders 7 are arranged at the bottom of the mounting frame 1 at positions corresponding to the pile foundations 6. During offshore construction, the post-pile method is adopted for pile insertion construction. First, the conductor frame platform is sunk to the seabed, and then the steel pipe piles are driven into the guide cylinders 7 respectively. Then, the guide cylinders 7 are docked and installed on the steel pipe piles. The overall installation of the mounting frame 1 is completed, and the next step is to install the cage 2.

[0081] The present invention installs the mounting frame 1 on the pile foundation 6 and the guide cylinder 7, which can ensure the stability of the mounting frame 1, thereby ensuring the stability of the inner net box 2 under the action of waves and water flow.

[0082] According to an embodiment of the present invention, on the other hand, Figure 4 As shown, an offshore wind power system is also provided, including the above-mentioned offshore farming equipment 100, a wind turbine 8 and a cable 9, wherein the wind turbine 8 is suitable for installation in the sea, and the cable 9 is electrically connected to the lifting assembly 3 and the wind turbine 8.

[0083] The power generated by the wind turbine 8 in the present invention can be used to operate the lifting component 3, which has good power resources and can realize the integration of the ocean ranch and the offshore wind farm.
