[0002] The main function of deep-sea cages is to cultivate marine aquatic products to meet people's demand for marine food. It is an important project of modern marine engineering. In recent years, offshore fishing has seriously damaged the marine ecological environment, especially the seabed vegetation and landforms. Offshore fish farming has led to a vicious cycle of water pollution. Therefore, the marine fish farming industry has gradually shifted to the deep sea.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0045] See also Figures 1 to 17 In one embodiment, a typhoon-resistant gravity cage includes a cage 10, a buoy 15 and a cable 1, wherein one end of the cage 10 is provided with a plurality of buoys 15, and both ends of the cage 10 are connected with the cable 1, and further includes a second driving member 4, a winding drum 6, a first telescopic rod 11, a second telescopic rod 18, a flexible net 17 and a stretching assembly;

[0046] The end of the cage 10 located on the water surface is nested on the nesting ring 7, the nesting ring 7 is retractable, a telescopic controller 12 is arranged at the axis of the nesting ring 7, the telescopic controller 12 is fixedly connected to the first telescopic rod 11, the end of the first telescopic rod 11 away from the telescopic controller 12 is connected to the nesting ring 7, the connection method is hook connection, the end of the first telescopic rod 11 is provided with an end hook 13, and the connection between the first telescopic rod 11 and the nesting ring 7 is realized by the end hook 13;

[0047] The nested ring 7 is fixedly mounted with a second driving member 4, the second driving member 4 is connected to the winding drum 6, the cable 1 located on the water surface is connected to the winding drum 6, and the second driving member 4 is used to drive the winding drum 6 to reel or unreel the cable 1;

[0048] The output end of the telescopic controller 12 is equipped with a sound wave generator 16, and a plurality of second telescopic rods 18 are installed on the circumference of the sound wave generator 16. The plurality of second telescopic rods 18 are closely arranged with a plurality of flexible nets 17 in the radial direction, and the flexible nets 17 are connected in series through the small holes at the end of each section of the second telescopic rod 18. A telescopic member 20 is installed on the side of the sound wave generator 16 away from the first telescopic rod 11, and an extension component is arranged on the output end of the telescopic member 20. A plurality of side hooks 36 and hook-connecting members 37 are installed on the extension component. The telescopic controller 12 is used to drive the second telescopic rod 18 and the sound wave generator 16 to move vertically, and the telescopic member 20 is used to drive the extension component to move vertically. The extension component is used to stretch and close to the inner wall of the net box 10, and is hooked and fixed to the side wall and the bottom of the net box 10 through the side hooks 36 and the hook-connecting members 37;

[0049] A counterweight box 24 is installed at the bottom of the net cage 10 . A water suction pump is arranged in the counterweight box 24 . A water suction port 27 and a water discharge port 29 are provided on the counterweight box 24 .

[0050] In this embodiment, the floating body 15 is provided with a vent valve 14. The floating body 15 can reduce the buoyancy of the net cage 10 by deflation through the vent valve 14, so that the net cage 10 is level with the sea level, reducing the impact of the typhoon on the net cage 10. At the same time, air can be taken in through the vent valve 14, thereby increasing the buoyancy and making the floating body 15 above the sea level.

[0051] A net hook 19 is fixedly installed at the end of the second telescopic rod 18, and the net hook 19 includes a first rotating shaft 19-1 and a hook. The first rotating shaft 19-1 is rotatably installed at the end of the second telescopic rod 18, and a third curved hook 19-2 is fixedly installed on the first rotating shaft 19-1. When the end of the second telescopic rod 18 is close to the net surface of the net box 10 and reaches a predetermined water depth under the action of the second telescopic rod 18, the first rotating shaft 19-1 is driven to rotate so that the third curved hook 19-2 is connected to the net surface;

[0052] The nesting ring 7 is provided with a bayonet 8 , and the clamping pin 9 passes through the bayonet 8 . The size of the nesting ring 7 can be fixed by the clamping pin 9 .

[0053] The first telescopic rod 11, the second telescopic rod 18, the telescopic member 20 and the telescopic controller 12 can adopt hydraulic telescopic or electric telescopic, and the specific form is not limited; the second driving member 4, the first driving member 3-1 and the rotating member 5 can adopt servo motors or stepper motors, and the specific selection is not limited.

[0054] In this embodiment, under normal circumstances, the upper nesting ring 7 and the first telescopic rod 11 are in an extended state, the bayonet 8 of the nesting ring 7 is stuck by the pin 9, the net box 10 is in an open state, and the float 15 sucks air through the vent valve 14 to allow the net box 10 to be above the water surface and in a floating state. The sound wave generator 16 does not work, and the second telescopic rod 18 is in a retracted state. The water suction pump in the counterweight box 24 does not work, and there is no water in the counterweight box 24. The net box 10 sags by its own weight, thereby expanding the space of the net box 10.

[0055] When a typhoon comes, the water suction pump in the counterweight box 24 starts to work. After the counterweight box 24 is filled with water, its weight increases, which lowers the center of gravity of the net cage 10, making it difficult for the net cage 10 to float up and down and move left and right on the sea surface, and at the same time expands the space under the net cage 10;

[0056] At the same time, the sound wave generator 16 starts to work, the second telescopic rod 18 starts to extend, the flexible net 17 and the second telescopic rod 18 extend from the upper part of the net box 10, adapt to the size of the net box 10, and start to drive the fish school. When it descends to a certain height through the telescopic controller 12, the telescopic member 20 extends downward for a certain distance, and then the extension assembly extends;

[0057] Then the clamping needle 9 is retracted, and the upper nested ring 7 is contracted under the action of the first telescopic rod 11, and the outer ring of the net box 10 is pulled inward, so that the outer ring of the net box 10 is formed into a small circle.

[0058] Even if the typhoon destroys the upper part of the cage 10, the lower part of the cage 10 forms a new small cage 10 under the action of the sound wave generator 16 and the flexible net 17, which protects the fish school, prevents the fish school from running around and lowers the center of gravity of the cage 10 to a certain extent. The float 15 is deflated through the vent valve 14 to reduce the buoyancy of the cage 10, so that the cage 10 is level with the sea level, reducing the impact of the typhoon on the cage 10. By controlling the center of gravity of the cage 10, the suction pump can suck water to pull the cage 10 as far as possible to the sea surface when the typhoon passes. After the strong wind, the excess water is discharged to make the cage 10 parallel to the sea surface.

[0059] See also Figures 7 to 10 In one embodiment, the extension component includes a power strut 30 and a variable diameter frame 21, a connecting rod 31, a support rod 33, a limit sleeve 32 and a multi-stage telescopic rod 34. The output end of the telescopic member 20 is installed with a power strut 30, and the output end of the power strut 30 is connected to the variable diameter frame 21. The variable diameter frame 21 is connected to a plurality of obliquely arranged connecting rods 31. Support rods 33 are arranged on both sides of one end of the connecting rod 31. Limit sleeves 32 are interactively installed between adjacent support rods 33. The support rod 33 and the limit sleeve 32 are located in the same horizontal plane. A multi-stage telescopic rod 34 is also fixedly installed at one end of the connecting rod 31. The multi-stage telescopic rod 34 is vertically arranged. The power strut 30 is used to drive the variable diameter frame 21 to perform variable diameter extension.

[0060] The power support rod 30 can be hydraulically retractable or electrically retractable, and the specific form is not limited.

[0061] In this embodiment, under normal circumstances, the upper nesting ring 7 and the first telescopic rod 11 are in an extended state, the bayonet 8 of the nesting ring 7 is stuck by the pin 9, the net box 10 is in an open state, and the float 15 sucks air through the vent valve 14 to allow the net box 10 to be above the water surface and in a floating state. The sound wave generator 16 does not work, and the second telescopic rod 18 is in a retracted state. The water suction pump in the counterweight box 24 does not work, and there is no water in the counterweight box 24. The net box 10 sags by its own weight, thereby expanding the space of the net box 10.

[0062] When a typhoon comes, the water suction pump in the counterweight box 24 starts to work. After the counterweight box 24 is filled with water, its weight increases, which lowers the center of gravity of the net cage 10 and makes it difficult for the net cage 10 to float up and down and move left and right on the sea surface.

[0063] At the same time, the sound wave generator 16 starts to work, the second telescopic rod 18 starts to extend, the flexible net 17 and the second telescopic rod 18 extend from the upper part of the net box 10, adapt to the size of the net box 10, and start to drive the fish school. When it is lowered to a certain height through the telescopic controller 12, the telescopic member 20 extends downward for a certain distance, and the power support rod 30 drives the variable diameter frame 21 to extend;

[0064] Then the clamping needle 9 is retracted, and the upper nested ring 7 is contracted under the action of the first telescopic rod 11, and the outer ring of the net box 10 is pulled inward, so that the outer ring of the net box 10 is formed into a small circle.

[0065] Even if the typhoon destroys the upper part of the cage 10, the lower part of the cage 10 forms a new small cage 10 under the action of the sound wave generator 16 and the flexible net 17, which protects the fish school, prevents the fish school from running around and lowers the center of gravity of the cage 10 to a certain extent. The float 15 is deflated through the vent valve 14 to reduce the buoyancy of the cage 10, so that the cage 10 is level with the sea level, reducing the impact of the typhoon on the cage 10. By controlling the center of gravity of the cage 10, the suction pump can suck water to pull the cage 10 as far as possible to the sea surface when the typhoon passes. After the strong wind, the excess water is discharged to make the cage 10 parallel to the sea surface.

[0066] In one embodiment, a buffer spring is installed inside the multi-stage telescopic rod 34 .

[0067] In this embodiment, the multi-stage telescopic rod 34 is composed of a plurality of rods that are nested and telescopically connected, and buffer springs are connected between adjacent rods to reduce the impact of the up and down floating of the cage 10 on the upper rods.

[0068] See also Fig.12 , Fig.13 In one embodiment, a clip 37 - 4 and a hook connection 37 are installed at one end of the multi-stage telescopic rod 34 away from the connecting rod 31 .

[0069] In this embodiment, the multi-stage telescopic rod 34 is composed of a plurality of rods that are nested and telescopically connected, and a buffer spring is connected between adjacent rods. A side hook 36 is installed on the outer surface of the single rod, and the connection between the rod and the side wall of the net box 10 can be achieved through the side hook 36. A clip 37-4 is installed on the rod at the bottom of the multi-stage telescopic rod 34, and the clip 37-4 can clamp the bottom of the multi-stage telescopic rod 34 to prevent it from falling off. The hook connector 37 includes a first hook 37-1, a second shaft 37-2, and a second hook 37-3. The lower end of the clip 37-4 is rotatably installed with two first hooks 37-1 through the second shaft 37-2. The end of the multi-stage telescopic rod 34 is circumferentially rotatably installed with a plurality of second hooks 37-3. The first hook 37-1 is opened by the second shaft 37-2, and the side net of the bottom is hooked and closed to achieve connection with the bottom side net. The second hook 37-3 is used to connect the net around the bottom of the net box 10.

[0070] The opening and closing hooks with large openings can increase the probability of hooking the cage 10 and reduce the probability of hooking barnacles on the cage 10.

[0071] See also Figures 7 to 10 In one embodiment, the variable diameter frame 21 includes an outer sleeve 21-1, an arc rod 21-2 and a third telescopic rod 21-3. A plurality of third telescopic rods 21-3 are installed at the output end of the telescopic member 20. The end of the third telescopic rod 21-3 away from the telescopic member 20 is connected to the outer sleeve 21-1, and an arc rod 21-2 is slidably installed between adjacent outer sleeves 21-1.

[0072] In this embodiment, under normal circumstances, the upper nesting ring 7 and the first telescopic rod 11 are in an extended state, the bayonet 8 of the nesting ring 7 is stuck by the pin 9, the net box 10 is in an open state, and the float 15 sucks air through the vent valve 14 to allow the net box 10 to be above the water surface and in a floating state. The sound wave generator 16 does not work, and the second telescopic rod 18 is in a retracted state. The water suction pump in the counterweight box 24 does not work, and there is no water in the counterweight box 24. The net box 10 sags by its own weight, thereby expanding the space of the net box 10.

[0073] When a typhoon comes, the water suction pump in the counterweight box 24 starts to work. After the counterweight box 24 is filled with water, its weight increases, which lowers the center of gravity of the net cage 10, making it difficult for the net cage 10 to float up and down and move left and right on the sea surface, and at the same time expands the space under the net cage 10;

[0074] At the same time, the sound wave generator 16 starts to work, the second telescopic rod 18 starts to extend, the flexible net 17 and the second telescopic rod 18 extend from the upper part of the net box 10, adapt to the size of the net box 10, and start to drive the fish school. When it is lowered to a certain height through the telescopic controller 12, the net hook 19 of the upper second telescopic rod 18 is controlled to hook the net box 10. After the telescopic member 20 extends downward for a certain distance, the power support rod 30 drives the outer sleeve 21-1 to move, and naturally drives the arc rod 21-2 to extend. The limit sleeve 32 and the support rod 33 are naturally extended to support the surrounding of the net box 10, and the multi-stage telescopic rod 34 extends downward;

[0075] Then the clamping needle 9 is retracted, and the upper nested ring 7 is contracted under the action of the first telescopic rod 11, and the outer ring of the net box 10 is pulled inward, so that the outer ring of the net box 10 is formed into a small circle.

[0076] Even if the typhoon destroys the upper part of the net cage 10, the lower part of the net cage 10 forms a new small net cage 10 under the action of the sound wave generator 16 and the second flexible net 17, which protects the fish school, prevents the fish school from running around and lowers the center of gravity of the net cage 10 to a certain extent. The float 15 is deflated through the vent valve 14 to reduce the buoyancy of the net cage 10, so that the net cage 10 is level with the sea level, reducing the impact of the typhoon on the net cage 10. By controlling the center of gravity of the net cage 10, the water suction pump can suck water to pull the net cage 10 as far as possible to the sea surface when the typhoon passes. After the strong wind, the excess water is discharged to make the net cage 10 parallel to the sea surface.

[0077] See also Figures 14 to 16 In one embodiment, a plurality of fourth telescopic rods 25 are circumferentially installed on the side wall of the counterweight box 24 , and the output ends of the fourth telescopic rods 25 are connected to circumferential counterweight cylinders, which are connected to the counterweight box 24 .

[0078] The fourth telescopic rod 25 can be hydraulically telescopic or electrically telescopic, and the specific form is not limited.

[0079] In this embodiment, under normal circumstances, the upper nesting ring 7 and the first telescopic rod 11 are in an extended state, the bayonet 8 of the nesting ring 7 is stuck by the pin 9, the net box 10 is in an open state, and the float 15 sucks air through the vent valve 14 to allow the net box 10 to be above the water surface and in a floating state. The sound wave generator 16 does not work, and the second telescopic rod 18 is in a retracted state. The water suction pump in the counterweight box 24 does not work, and there is no water in the counterweight box 24. The fourth telescopic rod 25 is in a retracted state, and the circumferential counterweight blocks are in a closed state, relying on their own weight to make the net box 10 sag, thereby expanding the space of the net box 10.

[0080] When a typhoon comes, the fourth telescopic rod 25 is extended to open the lower part of the net cage 10, and the water suction pump in the counterweight box 24 starts to work. The weight of the circumferential counterweight cylinder and the counterweight box 24 increases after water enters, which lowers the center of gravity of the net cage 10, making it difficult for the net cage 10 to float up and down and move left and right on the sea surface, and at the same time expands the space under the net cage 10;

[0081] At the same time, the sound wave generator 16 starts to work, the second telescopic rod 18 starts to extend, the flexible net 17 and the second telescopic rod 18 extend from the upper part of the net box 10, adapt to the size of the net box 10, and start to drive the fish school. When it is lowered to a certain height through the telescopic controller 12, the net hook 19 of the upper second telescopic rod 18 is controlled to hook the net box 10. After the telescopic member 20 extends downward for a certain distance, the power support rod 30 drives the outer sleeve 21-1 to move, and naturally drives the arc rod 21-2 to extend. The limit sleeve 32 and the support rod 33 are naturally extended to support the surrounding of the net box 10, and the multi-stage telescopic rod 34 extends downward;

[0082] Then the clamping needle 9 is retracted, and the upper nested ring 7 is contracted under the action of the first telescopic rod 11, and the outer ring of the net box 10 is pulled inward, so that the outer ring of the net box 10 is formed into a small circle.

[0083] Even if the typhoon destroys the upper part of the net cage 10, the lower part of the net cage 10 forms a new small net cage 10 under the action of the sound wave generator 16 and the second flexible net 17, which protects the fish school, prevents the fish school from running around and lowers the center of gravity of the net cage 10 to a certain extent. The float 15 is deflated through the vent valve 14 to reduce the buoyancy of the net cage 10, so that the net cage 10 is level with the sea level, reducing the impact of the typhoon on the net cage 10. By controlling the center of gravity of the net cage 10, the water suction pump can suck water to pull the net cage 10 as far as possible to the sea surface when the typhoon passes. After the strong wind, the excess water is discharged to make the net cage 10 parallel to the sea surface.

[0084] See also Figure 1 , Figure 3 In one embodiment, a rotating member 5 is installed on the winding reel 6, and a rotating button 2 is connected to the output end of the rotating member 5.

[0085] In this embodiment, the cable 1 is longer and rougher than the cable 1 of a normal gravity cage 10. The cable 1 passes through the rotating button 2. When the typhoon does not come, the rotating button 2 is in a locked state, and the second driving member 4 does not work, so that the cable 1 of the cage 10 is in the same state as the cable 1 of the normal gravity cage 10. When the typhoon comes, the rotating button 2 is opened, and the rotating member 5 drives the cable 1 to rotate to a certain angle to clamp the cable 1. If the cable 1 moves, it will consume a lot of energy. When the typhoon comes, the twisted rotating button 2 offsets the large impact force of the typhoon on the cage 10 and protects the cage 10. And the cable 1 of the cage 10 is longer than the cable 1 of the normal gravity cage 10, so it has a larger range of movement space, which can greatly reduce the energy of the direct impact of the typhoon on the cage 10. When the cable 1 of the cage 10 is pulled to the limit range, the second driving member 4 is started, so that the machine can put the cable 1 in a state of resisting the typhoon. When the impact of a typhoon is too great, the second driving member 4 can also provide a force opposite to the typhoon to pull the cable 1 .

[0086] See also Figures 1 to 5 In one embodiment, a clamping assembly 3 is installed on the rotating button 2, and the clamping assembly 3 is used to clamp the surface of the cable 1.

[0087] In this embodiment, the cable 1 passes through the clamping assembly 3 and the rotating button 2. The clamping assembly 3 is in the hole of the rotating button 2. The surface of the cable 1 can be clamped by the clamping assembly 3, which can increase the resistance to the movement of the cable 1, thereby offsetting part of the impact force generated by the typhoon.

[0088] See also Figures 1 to 5 In one embodiment, the clamping assembly 3 includes a driving member, a contraction frame 3-2 and a cable sleeve 3-3, the driving member is installed on the rotating button 2, the cable 1 passes through the cable sleeve 3-3 and is connected to the winding drum 6, the cable sleeve 3-3 is installed in the contraction frame 3-2, and the driving member is used to drive the contraction frame 3-2 to change diameter and contract.

[0089] In this embodiment, the clamping assembly 3 is composed of three parts: a driving member, a contraction frame 3-2 and a cable sleeve 3-3. The rotation of the driving member controls the tightness of the contraction frame 3-2 to control whether the cable 1 is locked. When the typhoon is not coming, the rotating button 2 and the clamping assembly 3 are both in a locked state, and the clamping assembly 3 does not work, so that the cable 1 of the net box 10 is in the same state as the cable 1 of the normal gravity net box 10. When the typhoon comes, the rotating button 2 is opened and rotated to a certain angle to clamp the cable 1. If the cable 1 moves, a large amount of energy will be consumed. The clamping assembly 3 does not completely clamp the cable 1, but the movement of the cable 1 in the clamping assembly 3 also consumes a large amount of energy. The force of the typhoon on the net box 10 directly impacting the net box 10 is offset by the movement of the cable 1 in the rotating button 2 and the clamping assembly 3, thereby protecting the net box 10.

[0090] The present invention also provides a method for using a typhoon-resistant gravity cage, including the above-mentioned typhoon-resistant gravity cage 10, and the method specifically includes:

[0091] The water suction pump in the counterweight box 24 starts to work, and the weight of the counterweight box 24 increases after water enters;

[0092] The sonic wave generator 16 is started to drive the second telescopic rod 18 to extend, and when the flexible net 17 is close to the inner wall of the net box 10, the extension is stopped;

[0093] The telescopic controller 12 is started to drive the acoustic wave generator 16 and the flexible net 17 to descend. When they descend to a certain height, the telescopic member 20 is started to drive the extension assembly to descend to the bottom of the net box 10 through the telescopic member 20. Then the extension assembly completes the extension and props up the net surface of the net box 10, and is hooked and fixed to the side wall and the bottom of the net box 10 through the side hooks 36 and the hook connection member 37;

[0094] The first telescopic rod 11 is activated to shrink the upper nested ring 7 and pull the outer ring of the cage 10 inward.

[0095] The float 15 is deflated through the vent valve 14 to reduce the buoyancy of the net cage 10, so that the net cage 10 is level with the sea level.
