[0067] 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.

[0068] Combine the following Figures 1 to 4 , describing an embodiment of the present invention.

[0069] According to an embodiment of the present invention, on the one hand, Figures 1 to 3As shown, a breeding equipment 100 is provided, including a mounting frame 1, a net cage 2 and a lifting assembly 3. The interior of the mounting frame 1 is a accommodating cavity with an opening on the top. The bottom of the mounting frame 1 is suitable for being set in water, and the top is exposed above the water surface. The net cage 2 includes a bottom frame 201, a top frame 202 and a net. The bottom frame 201 is set inside the mounting frame 1, and the top frame 202 is set inside the mounting frame 1. The size of the top frame 202 is larger than that of the bottom frame 201. The net is set on the outside of the bottom frame 201 and the top frame 202, and the inside of the net is a breeding cavity. One end of the lifting assembly 3 is fixed to the mounting frame 1, and the other end is connected to the bottom frame 201. The lifting assembly 3 has a breeding state of driving the bottom frame 201 away from the top frame 202, and a maintenance state of driving the bottom frame 201 close to the top frame 202.

[0070] Specifically, in this embodiment, there is no specific limitation on the applicable scenario of the aquaculture equipment 100. In this embodiment, the aquaculture equipment 100 is set in the sea.

[0071] In this embodiment, the shape of the mounting frame 1 is not specifically limited. In this embodiment, the mounting frame 1 is a cubic frame structure with a cavity inside and an open top. In order to reduce the erosion of the mounting frame 1 by seawater, the mounting frame 1 is made of stainless steel in this embodiment. In other implementations, the mounting frame 1 may also adopt a frame structure with a circular or polygonal cross section.

[0072] In this example, the bottom of the mounting frame 1 is set in the sea water, and the top opening is higher than the sea level 9. The cage 2 is set inside the mounting frame 1, and the cage 2 is used to breed aquatic animals such as fish, shrimp, shellfish, etc.

[0073] In this embodiment, the shapes of the top frame 202 and the bottom frame 201 match the mounting frame 1, and the sizes of the top frame 202 and the bottom frame 201 are smaller than the size of the mounting frame 1, so that the top frame 202 and the bottom frame 201 can be placed in the mounting frame 1, and the size of the bottom frame 201 is smaller than the size of the top frame 202. The net is installed on the outside of the top frame 202 and the bottom frame 201, and the top frame 202 is installed in the mounting frame 1 near the opening. The position of the top frame 202 is higher than the sea level 9, and the position of the bottom frame 201 is lower than the top frame 202. The lifting component 3 is installed at the top opening of the mounting frame 1 and is connected to the bottom frame 201. When the net is damaged or needs maintenance, the bottom frame 201 is driven to move upward by operating the lifting component 3, and is lifted to the opening after passing through the top frame 202. The operator can replace, clean and perform other maintenance operations on the net installed on the top frame 202 and the bottom frame 201.

[0074] In this embodiment, a net is provided on the periphery between the top frame 202 and the bottom frame 201 to surround the water body, thereby ensuring that the fish can survive in a limited space.

[0075] In this embodiment, the net includes vertical net skeleton ropes 203, transverse net skeleton ropes and segmented nets. The vertical net skeleton ropes 203 are connected between the top frame 202 and the bottom frame 201, and the transverse net skeleton ropes are perpendicularly intersected with the vertical net skeleton ropes 203. The segmented nets are installed on the vertical net skeleton ropes 203 and the transverse net skeleton ropes.

[0076] During operation and breeding, the net cage 2 is normally placed in the water; during operation and maintenance, the vertical net frame rope 203 arranged in the inner space of the net is lifted to the opening position through the lifting component 3, and the height is greater than the top frame 202.

[0077] The present invention sets the size of the bottom frame 201 to be smaller than the top frame 202. When the net needs to be maintained, the lifting assembly 3 can be used to lift the bottom frame 201 located in the mounting frame 1 through the top frame 202 to the open position, thereby facilitating maintenance such as replacement or cleaning of the net installed on the top frame 202 and the bottom frame 201. It has the advantages of simple structure and convenient operation, and the maintenance personnel can complete the maintenance of the net at the opening on the top of the mounting frame 1.

[0078] 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 bottom frame 201 , and the other end is movably connected to the first driver 301 .

[0079] 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 at the opening. One end of the first pull rope 302 is set on the bottom frame 201, and the other end is set on the winch. The first pull rope 302 is tightened by the operation of the winch, so as to lift the bottom frame 201 to the opening. After the maintenance of the net is completed, the winch is driven to reverse and the bottom frame 201 is put back into the sea.

[0080] In the present invention, the first driver 301 is used to control the first pull rope 302 to rise, so that the bottom frame 201 connected to the pull rope can be lifted to the opening. The first drivers 301 symmetrically installed on both sides of the opening can ensure that the bottom frame 201 always remains stable during the lifting process.

[0081] In one embodiment, Figure 2 and Figure 3 As shown, the lifting assembly 3 also includes connecting ropes 303, and multiple connecting ropes 303 connect the top frame 202 and the bottom frame 201. The connecting ropes 303 have a maintenance state that drives the bottom frame 201 close to one side of the top frame 202, and a breeding state that drives the bottom frame 201 to be located in the middle of the top frame 202.

[0082] Specifically, in this embodiment, there is no specific limitation on the number of connecting ropes 303. In this embodiment, four connecting ropes 303 are provided in total, which are symmetrically arranged in pairs and are respectively connected between the top frame 202 and the bottom frame 201. By tightening the first connecting rope 3031 and the second connecting rope 3032 on one side and loosening the third connecting rope 3033 and the fourth connecting rope 3034 on the opposite side, the bottom frame 201 can be moved close to one side of the top frame 202.

[0083] The present invention adopts the connecting rope 303 to connect the top frame 202 and the bottom frame 201. When the bottom frame 201 is lifted to the opening position, the connecting rope 303 on one side is tightened and the connecting rope 303 on the other side is loosened, so that the bottom frame 201 can be moved toward one side of the top frame 202, so that the operator can maintain the net. After completing the maintenance on one side, the connecting rope 303 on the other side is tightened, and the connecting rope 303 on the opposite side is loosened, and the other side of the bottom frame 201 is moved toward the top frame 202. The net at various locations on the bottom frame 201 can be maintained by sequentially performing the operations.

[0084] In one embodiment, Figure 1 As shown, the lifting assembly 3 also includes a second driver 304, a fixed pulley 305 and a second pull rope 306. The two second drivers 304 are respectively installed on both sides of the opening, and the two fixed pulleys 305 are respectively installed on the bottom of the mounting frame 1. One end of the second pull rope 306 is connected to the bottom frame 201, and the other end is movably connected to the second driver 304. The second pull rope 306 is movably installed on the fixed pulley 305.

[0085] Specifically, in this embodiment, brackets 311 are respectively installed on the inner walls of both sides of the mounting frame 1 at the bottom position, and the fixed pulley 305 is installed on the bracket 311. On the inner wall of the mounting frame 1, a plurality of pull rings 312 are installed at the position between the opening and the bracket 311. The second driver 304 is a winch installed at the opening. One end of the second pull rope 306 is connected to the bottom frame 201, and the other end is installed on the winch. The second pull rope 306 is passed through the pull ring 312 and is wound around the fixed pulley 305.

[0086] In the present invention, pulling in the second pull rope 306 can stably set the bottom frame 201 at the bottom position of the mounting frame 1, thereby supporting the net between the top frame 202 and the bottom frame 201, and realizing the breeding of aquatic animals. When the net needs to be maintained, the second pull rope 306 is loosened, and the first pull rope 302 is lifted at the same time to lift the bottom frame 201 and the net upward to the opening for maintenance.

[0087] In one embodiment, Figure 1As shown, the lifting assembly 3 also includes a third driver 307 and a third pull rope 308. The two third drivers 307 are respectively installed on the inner walls on both sides of the mounting frame 1. The third driver 307 is located below the first driver 301 and the second driver 304. One end of the third pull rope 308 is connected to the top frame 202, and the other end is movably connected to the third driver 307.

[0088] Specifically, in this embodiment, the third driver 307 is a winch, and one end of the third pull rope 308 is connected to the top frame 202 and the other end is connected to the winch. The tension or relaxation degree of the third pull rope 308 can be controlled by the winch. When the third pull rope 308 is tightened, the top frame 202 can be maintained in the middle position in the mounting frame 1. Under the impact of waves and water currents, the shaking of the top frame 202 can be slowed down to avoid collision between the top frame 202 and the mounting frame 1.

[0089] The third pull rope 308 of the present invention can ensure that the movement distance of the entire net cage 2 is controlled under the action of waves and water currents, thereby avoiding collision between the net cage 2 and the mounting frame 1.

[0090] In one embodiment, Figure 1 As shown, the lifting assembly 3 further includes a first platform 309 , and two first platforms 309 are respectively installed on both sides of the opening, and the first driver 301 and the second driver 304 are arranged on the first platforms 309 .

[0091] Specifically, in this embodiment, the first platform 309 is arranged at the opening and extends toward the center of the opening. The first driver 301 and the second driver 304 are installed on the first platform 309. The inward extension length of the first platform 309 is not greater than the distance between the bottom frame 201 and the inner wall of the mounting frame 1, so as to lift the bottom frame 201 to the position of the first platform 309.

[0092] The first platform 309 of the present invention is provided to facilitate installation of the first driver 301 and the second driver 304 , and can also be used by operators to maintain the net on the first platform 309 .

[0093] In one embodiment, Figure 1 As shown, the lifting assembly 3 also includes a second platform 310 . The two second platforms 310 are respectively mounted on the inner walls on both sides of the mounting frame 1 . The second platform 310 is located below the first platform 309 .

[0094] Specifically, in this embodiment, the second platform 310 is disposed below the first platform 309 , the size of the second platform 310 is smaller than the size of the first platform 309 , and the installation height of the second platform 310 is higher than the sea level 9 .

[0095] In one embodiment, Figure 1As shown, the farming equipment 100 further includes a connecting ring 4 , a plurality of connecting rings 4 are arranged on the bottom frame 201 , and the second pull rope 306 is connected to the connecting ring 4 .

[0096] Specifically, in this embodiment, the connecting ring 4 is arranged on the four corners of the rectangular bottom frame 201, and the second pull rope 306 is connected to the connecting ring 4. When the second pull rope 306 is attached to marine organisms or damaged and needs to be replaced, the four corners of the bottom frame 201 are pulled up to the height of the first platform 309 as a whole, and temporarily fixed, and the connecting ring 4 of the bottom frame 201 is connected with the temporary pull rope to ensure that the bottom frame 201 does not fall; at this time, one end of a new second pull rope 306 is connected to the second pull rope 306 that has been untied from the connecting ring 4, and then the other end of the new second pull rope 306 is connected to the other end of the original second pull rope 306 to form a loop, and the second driver 304 is cyclically rotated until the new second pull rope 306 is completely replaced to the original position of the damaged second pull rope 306, and then the new second pull rope 306 is fixed to the connecting ring 4, and finally the bottom frame 201 is lowered.

[0097] In the present invention, a connecting ring 4 is provided on the bottom frame 201. When the second pull rope 306 is attached with marine organisms or is damaged and needs to be replaced, a new second pull rope 306 is connected to the pull rope to be replaced to form a loop. The second driver 304 is cyclically rotated until the new second pull rope 306 is completely replaced in place to the original position of the damaged second pull rope 306. Then, the second pull rope 306 can be replaced. During replacement, the position of the bottom frame 201 remains unchanged, and the breeding conditions in the cage 2 are not affected.

[0098] In one embodiment, Figure 1 As shown, the breeding equipment 100 further includes pile foundations 5 and guide cylinders 6 . A plurality of pile foundations 5 are suitable for being arranged on the bottom of the water. A plurality of guide cylinders 6 are installed at the bottom of the mounting frame 1 , and the pile foundations 5 are installed in the guide cylinders 6 .

[0099] Specifically, in this embodiment, the number of pile foundations 5 is not specifically limited. In this embodiment, a total of four pile foundations 5 are arranged, and the pile foundations 5 are steel pipe piles. Four guide cylinders 6 are arranged at the bottom of the mounting frame 1 at positions corresponding to the pile foundations 5. During offshore construction, the post-pile method is used 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 6 respectively. Then, the guide cylinders 6 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.

[0100] The present invention installs the mounting frame 1 on the pile foundation 5 and the guide tube 6, 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.

[0101] According to an embodiment of the present invention, on the other hand, Figure 4As shown, an offshore wind power system is also provided, comprising the above-mentioned farming equipment 100 , a wind turbine 7 and a cable 8 , wherein the wind turbine 7 is suitable for installation in the sea, and the cable 8 is electrically connected to the lifting assembly 3 and the wind turbine 7 .

[0102] The power generated by the wind turbine 7 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.

[0103] According to an embodiment of the present invention, on the other hand, a method for maintaining the net of aquaculture equipment 100 is provided, which is used for the above-mentioned aquaculture equipment 100. The maintenance method includes:

[0104] Operate the first driver 301 to tighten the first pull rope 302, and synchronously operate the second driver 304 to release the second pull rope 306;

[0105] Lift the bottom frame 201 to the height of the first platform 309 and lift the top frame 202 to the height of the second platform 310;

[0106] Tighten the connection rope 303 on one side and release the connection rope 303 on the other side to drive the bottom frame 201 to approach one side inside the top frame 202;

[0107] Replace or clean nets;

[0108] Adjust the connecting rope 303 so that the bottom frame 201 is located in the middle of the top frame 202;

[0109] The first pull rope 302 and the second pull rope 306 are released, and the bottom frame 201 is placed in the water at a position at the bottom of the top frame 202 .

[0110] Specifically, in the present embodiment, all the pull ropes are provided with sufficient length at the rear end of the winch. When the net or the pull rope needs maintenance, the second side pull rope 306 is first completely released through the second driver 304, and the first pull rope 302 is simultaneously tightened through the first driver 301. Since the size of the bottom frame 201 is smaller than the top frame 202, the first driver 301 and the second driver 304 are gradually operated to lift the bottom frame 201 to the plane elevation of the upper first platform 309; at the same time, the third pull rope 308 is continuously tightened through the third driver 307 to prevent the top frame 202 from shaking, so that the top frame 202 is lifted to the plane elevation of the second platform 310.

[0111] Then, tighten the first connecting rope 3031 and the second connecting rope 3032 in turn, and release the third connecting rope 3033 and the fourth connecting rope 3034 at the same time, so that the bottom frame 201 moves closer to the side of the top frame 202, and then manually replace the clean net or dry it in the sun and clean it with a high-pressure water gun; according to this method, tighten the third connecting rope 3033 and the fourth connecting rope 3034 in turn, release the first connecting rope 3031 and the second connecting rope 3032, adjust the bottom frame 201 to the center position, and then release the first pull rope 302 and the second pull rope 306 to place the net box 2 in the sea water.

[0112] In this embodiment, in order to ensure that the movement distance of the net box 2 as a whole is controlled under the action of waves and water currents, a third driver 307 is specially arranged on the second platform 310, and is connected to the connecting ring 4 at the top frame 202 through a third pull rope 308. The length of the third pull rope 308 has sufficient margin. By arranging at least four third pull ropes 308 on the mounting frame 1, the swing amplitude of the net box 2 around can be controlled and the collision with the mounting frame 1 can be avoided.

[0113] In this embodiment, in order to ensure that the net box 2 does not collide with the structure and cause damage to each other during the process of small-scale rise and fall and left and right swinging due to being too close to the mounting frame 1, the second platform 310 is set to be a certain distance higher than the top elevation of the net box 2 in terms of height collision prevention; in terms of horizontal collision prevention, the plane projection of the top frame 202 and the second platform 310 is separated by a certain distance, on the one hand, to ensure that the third pull rope 308 is kept at a certain angle to the inside of the mounting frame 1, and on the other hand, the top frame 202 of the net box 2 will not collide with the mounting frame 1 under the action of hydrodynamic force, and will not collide with the second platform 310. The collision problem is avoided by setting a safe horizontal distance and a safe elevation difference.

[0114] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
