Description

Technical Field

[0001] The invention belongs to the technical field of deep-sea aquaculture, and in particular is a typhoon-resistant gravity cage. Background Art

[0002] Deep-sea cages are primarily used to cultivate marine aquatic products to meet the human demand for marine food, making them a key component of modern marine engineering. In recent years, near-shore fishing has severely damaged the marine ecosystem, particularly the seabed vegetation and landforms. This has led to a vicious cycle of water pollution, resulting in a gradual shift of marine fish farming to the deep ocean.

[0003] However, the deep-sea conditions in the open ocean are harsh, and there is a high probability of encountering extreme sea conditions such as typhoons. The deep-sea aquaculture cage structures in existing technologies have relatively weak anti-overturning capabilities and the ability to cope with extreme sea conditions such as typhoons.

[0044] Embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the accompanying drawings are exemplary and are only used to explain the present application and cannot be understood as a limitation of the present application.

[0045] Please refer to Figures 1 to 17 In one embodiment, a typhoon-resistant gravity type net cage includes a net cage 10, a floating body 15 and a cable 1, one end of the net cage 10 is provided with a plurality of floating bodies 15, both ends of the net cage 10 are connected with the cable 1, further includes a second driving member 4, a winding reel 6, a first telescopic rod 11, a second telescopic rod 18, a flexible net 17 and an extension assembly;

[0046] The net cage 10 is nested on a nesting ring 7 at one end on the water surface, the nesting ring 7 is telescopic, the nesting ring 7 is provided with a telescopic controller 12 at the shaft center, the telescopic controller 12 is fixedly connected with the first telescopic rod 11, one end of the first telescopic rod 11 away from the telescopic controller 12 is connected with the nesting ring 7 in the form of hooking, 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 through the end hook 13;

[0047] The second driving member 4 is fixedly installed on the nesting ring 7, the second driving member 4 is connected with the winding reel 6, the cable 1 on the water surface is connected with the winding reel 6, and the second driving member 4 is used to drive the winding reel 6 to wind or unwind the cable 1;

[0048] The output end of the telescopic controller 12 is provided with a sound wave generator 16, a plurality of second telescopic rods 18 are installed circumferentially on the sound wave generator 16, a plurality of flexible nets 17 are closely arranged in the radial direction on the second telescopic rods 18, the flexible nets 17 are connected in series through the small holes at the ends of each section of the second telescopic rods 18, the telescopic controller 12 is used to drive the second telescopic rods 18 and the sound wave generator 16 to move vertically, the telescopic controller 12 is used to drive the extension assembly to move vertically, the extension assembly is used to occur extension to tightly contact the inner side wall of the net cage 10, and the extension assembly is fixedly connected with the side wall and the bottom of the net cage 10 through the side hooks 36 and the hooking members 37;

[0049] A counterweight box 24 is installed at the bottom of the net cage 10 . A water suction pump is provided 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 float 15 is provided with a vent valve 14. When the float 15 is deflated through the vent valve 14, the buoyancy of the cage 10 can be reduced, so that the cage 10 is level with the sea level, thereby reducing the impact of typhoons on the cage 10. At the same time, air can be introduced through the vent valve 14 to increase the buoyancy, so that the float 15 is above the sea level.

[0051] A net hook 19 is fixedly mounted on the end of the second telescopic rod 18. The net hook 19 includes a first rotating shaft 19-1 and a hook. The first rotating shaft 19-1 is rotatably mounted on the end of the second telescopic rod 18. A third curved hook 19-2 is fixedly mounted on the first rotating shaft 19-1. When the second telescopic rod 18 is used to move the end of the second telescopic rod 18 close to the net surface of the net cage 10 and the water depth reaches a predetermined level, the first rotating shaft 19-1 is driven to rotate, thereby connecting the third curved hook 19-2 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 be hydraulically telescopic or electrically 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 be 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 extended, the latch 8 of the nesting ring 7 is locked by the latch pin 9, and the net cage 10 is in an open position. The float 15 draws air through the vent valve 14, allowing the net cage 10 to float above the water surface. The acoustic wave generator 16 is inoperative, and the second telescopic rod 18 is retracted. The water pump in the counterweight box 24 is inoperative, and the counterweight box 24 is free of water. Its own weight causes the net cage 10 to sag, expanding the space within the net cage 10.

[0055] When a typhoon comes, the water suction pump in the counterweight box 24 starts working. When 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, while expanding 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 cage 10, adapting to the size of the net cage 10, and start to drive the fish. 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 extension assembly extends;

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

[0058] Even if a typhoon damages the upper portion of cage 10, the lower portion, activated by the acoustic wave generator 16 and flexible net 17, forms a new, smaller cage 10, protecting the fish and preventing them from escaping. This also lowers the cage's center of gravity to a certain extent. Floating body 15 is deflated through vent valve 14, reducing the cage's buoyancy and leveling it with the sea, thus mitigating the typhoon's impact. By controlling the cage's center of gravity, the suction pump draws water during a typhoon, pulling the cage 10 as close to the sea surface as possible. After the strong winds subside, excess water is drained, bringing the cage 10 back to a level with the sea.

[0059] See also Figures 7 to 10 In one embodiment, the extension assembly 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 equipped 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 provided on both sides of one end of the connecting rod 31. A limit sleeve 32 is movably 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 extended, the latch 8 of the nesting ring 7 is locked by the latch pin 9, and the net cage 10 is in an open position. The float 15 draws air through the vent valve 14, allowing the net cage 10 to float above the water surface. The acoustic wave generator 16 is inoperative, and the second telescopic rod 18 is retracted. The water pump in the counterweight box 24 is inoperative, and the counterweight box 24 is free of water. Its own weight causes the net cage 10 to sag, expanding the space within the net cage 10.

[0062] When a typhoon comes, the water suction pump in the counterweight box 24 starts working. When water enters the counterweight box 24, 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 or 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 cage 10, adapting to the size of the net cage 10 and starting to drive the fish. When it is lowered to a certain height through the telescopic controller 12, the telescopic member 20 extends downward a certain distance, and the power support rod 30 drives the variable diameter frame 21 to extend;

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

[0065] Even if a typhoon damages the upper portion of cage 10, the lower portion, activated by the acoustic wave generator 16 and flexible net 17, forms a new, smaller cage 10, protecting the fish and preventing them from escaping. This also lowers the cage's center of gravity to a certain extent. Floating body 15 is deflated through vent valve 14, reducing the cage's buoyancy and leveling it with the sea, thus mitigating the typhoon's impact. By controlling the cage's center of gravity, the suction pump draws water during a typhoon, pulling the cage 10 as close to the sea surface as possible. After the strong winds subside, excess water is drained, bringing the cage 10 back to a level with the sea.

[0066] In one embodiment, a buffer spring is installed in 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 Figure 12 、 Figure 13 In one embodiment, a clip 37 - 4 and a hook 37 are installed at one end of the multi-stage telescopic rod 34 away from the connecting rod 31 .

[0069] The hook 37-3 is used to connect 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. Several 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 the 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 extended, the latch 8 of the nesting ring 7 is locked by the latch pin 9, and the net cage 10 is in an open position. The float 15 draws air through the vent valve 14, allowing the net cage 10 to float above the water surface. The acoustic wave generator 16 is inoperative, and the second telescopic rod 18 is retracted. The water pump in the counterweight box 24 is inoperative, and the counterweight box 24 is free of water. Its own weight causes the net cage 10 to sag, expanding the space within the net cage 10.

[0073] When a typhoon comes, the water suction pump in the counterweight box 24 starts working. When 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, while expanding the space under the net cage 10.

[0074] At the same time, the sound wave generator 16 starts working, 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 cage 10, adapting to the size of the net cage 10 and starting to drive the fish. 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 cage 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, naturally driving the arc rod 21-2 to extend, the limit sleeve 32 and the support rod 33 naturally extend, supporting the four sides of the net cage 10, and the multi-stage telescopic rod 34 extends downward;

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

[0076] Even if a typhoon damages the upper portion of cage 10, the lower portion, activated by the acoustic wave generator 16 and the second flexible net 17, forms a new, smaller cage 10, protecting the fish and preventing them from escaping. This also lowers the cage's center of gravity to a certain extent. Floating body 15 is deflated through vent valve 14, reducing the cage's buoyancy and leveling it with the sea, thus mitigating the typhoon's impact. By controlling the cage's center of gravity, the suction pump draws water during a typhoon, pulling the cage 10 as close to the sea surface as possible. After the strong winds subside, excess water is drained, bringing the cage 10 back to a level with the sea.

[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 the circumferential counterweight cylinder, which is 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 extended, the latch 8 of the nesting ring 7 is locked by the locking pin 9, the net cage 10 is in an expanded state, and the float 15 draws air through the vent valve 14, allowing the net cage 10 to remain above the water surface and float. The acoustic wave generator 16 is inoperative, and the second telescopic rod 18 is retracted. The water pump in the counterweight box 24 is inoperative, and the counterweight box 24 is empty. The fourth telescopic rod 25 is retracted, and the circumferential counterweights are closed. The net cage 10 sags downward under its own weight, thereby expanding the space within the net cage 10.

[0080] When the typhoon comes, the fourth telescopic rod 25 is extended to support the lower part of the net cage 10, and the water pump in the counterweight box 24 starts to work. After the circumferential counterweight cylinder and the counterweight box 24 are filled with water, the weight increases, which lowers the center of gravity of the net cage 10, so that the net cage 10 is not easy to float up and down and move left and right on the sea surface, and the space of the lower part of the net cage 10 is expanded;

[0081] At the same time, the sound wave generator 16 starts to work, and the second telescopic rod 18 starts to extend. The flexible net 17 and the second telescopic rod 18 are stretched from the upper part of the net cage 10, adapt to the size of the net cage 10, and start to drive the fish. When the telescopic controller 12 is lowered to a certain height, the net hook 19 of the second telescopic rod 18 at the upper part controls the hooking of the net cage 10. After the telescopic part 20 is stretched downward by a certain distance, the power support rod 30 drives the outer sleeve 21-1 to move, which naturally drives the arc-shaped rod 21-2 to stretch. The limiting sleeve 32 and the support rod 33 are naturally stretched, supporting the net cage 10 around, and the multi-stage telescopic rod 34 is stretched downward.

[0082] Then the clamping needle 9 is retracted, and the upper nesting ring 7 is retracted under the action of the first telescopic rod 11, pulling the outer ring of the net cage 10 inward, so that the outer ring of the net cage 10 is synthesized 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, protecting the fish and preventing the fish from running away to a certain extent. The center of gravity of the net cage 10 is reduced. The float 15 is deflated through the air valve 14 to reduce the buoyancy of the net cage 10, so that the net cage 10 and the sea level are horizontal, reducing the impact of the typhoon on the net cage 10. By controlling the center of gravity of the net cage 10, the water pump can be used to suck water to pull the net cage 10 down to the sea surface as much as possible when the typhoon passes. After the strong wind, the excess water is discharged, so that the net cage 10 and the sea level are parallel.

[0084] Please refer to Figure 1 、 Figure 3 In one embodiment, a rotating part 5 is installed on the winding reel 6, and the output end of the rotating part 5 is connected with the rotary button 2.

[0085] In this embodiment, the cable 1 is longer and rougher than the cable 1 of a typical gravity cage 10. The cable 1 passes through a rotating button 2. Before a typhoon, the rotating button 2 is locked, and the second drive element 4 is inoperative, leaving the cable 1 of the cage 10 in the same state as the cable 1 of a typical gravity cage 10. When a typhoon approaches, the rotating button 2 opens, and the rotating element 5 rotates a certain angle to lock the cable 1. Moving the cable 1 would require significant energy. During a typhoon, the twisting rotating button 2 offsets the significant impact of the typhoon on the cage 10, protecting it. Furthermore, the cable 1 of this cage 10 is longer than that of a typical gravity cage 10, allowing for greater range of movement, significantly reducing the direct impact energy of the typhoon on the cage 10. When the cable 1 of the cage 10 is stretched to its limit, the second drive element 4 activates, allowing the machine to pull the cable 1 back into a typhoon-resistant position. When the impact of the typhoon is too strong, 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 located 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. The driving member is used to drive the contraction frame 3-2 to change its diameter and contract.

[0089] In this embodiment, the clamping assembly 3 consists of three parts: a driver, a retraction frame 3-2, and a cable sleeve 3-3. Rotation of the driver controls the tension of the retraction frame 3-2, thereby controlling the locking of the cable 1. Before a typhoon approaches, the rotating knob 2 and the clamping assembly 3 are both locked, and the clamping assembly 3 is inactive, leaving the cable 1 of the cage 10 in the same state as the cable 1 of a normal gravity cage 10. When a typhoon approaches, the rotating knob 2 opens and rotates a certain angle to clamp the cable 1. Any movement of the cable 1 requires significant energy. While the clamping assembly 3 does not fully clamp the cable 1, the movement of the cable 1 within the clamping assembly 3 still requires significant energy. The force of a typhoon directly impacting the cage 10 is offset by the movement of the cable 1 within the rotating knob 2 and the clamping assembly 3, thus protecting the cage 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 comprises:

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

[0093] The telescopic controller 12 is activated 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 activated, and the telescopic member 20 drives the extension assembly to descend to the bottom of the net box 10. Then, the extension assembly completes its extension and props up the net surface of the net box 10, and is hooked and fixed to the side wall and bottom of the net box 10 through the side hooks 36 and the hook connecting 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 cage 10 so that the cage 10 is level with the sea level.
