Description

Technical Field

[0002] An ocean ranch refers to an artificial fishing ground set up in a specific sea area for the planned cultivation and management of fishery resources. The netting is an important part of the ocean ranch. After long-term use, a large number of marine organisms, such as seaweed, barnacles, etc., will attach to its surface. If these organisms are not cleaned in time, it will cause the mesh to be blocked, the oxygen content in the water body to decrease, the quality of the netting to increase, and the netting to deform.

[0056] Referring to Figures 1 to 11 , the present invention provides a self-rotating marine ranch 100, comprising:

[0057] A net cage 10, an aquaculture space 11 is formed inside the net cage 10, and a plurality of water passing holes 12 are provided on the outer surface of the net cage 10, and the water passing holes 12 communicate with the aquaculture space 11;

[0058] A net 20, the net 20 is sleeved on the outer surface of the net cage 10; and

[0059] A boosting mechanism 30, the boosting mechanism 30 is arranged on the outer surface of the net cage 10, and is used to interact with environmental loads to generate a boosting force, so that the net cage 10 rotates.

[0060] The self-rotating marine ranch 100 of the technical solution of the present invention includes a net cage 10, a net 20 and a boosting mechanism 30. The net 20 is sleeved on the outer surface of the net cage 10 to confine aquaculture products in the aquaculture space 11 for cultivation, so that they cannot swim out of the aquaculture space 11 through the water passing holes 12. The boosting mechanism 30 is arranged on the outer surface of the net cage 10. When environmental loads (such as waves, tides, currents, etc.) in the ocean act on the boosting mechanism 30, the environmental loads will apply a boosting force to the boosting mechanism 30, thereby driving the net cage 10 to rotate. During the rotation of the net 20 following the net cage 10, the attachment of marine organisms on the net 20 can be reduced, thereby realizing the automatic cleaning of the net 20 and reducing the maintenance cost of the net 20.

[0061] When environmental loads such as waves, tides, currents, etc. act on the boosting mechanism 30, since the boosting mechanism 30 is connected to the net cage 10, the net cage 10 is subjected to the acting force of the environmental loads and will rotate.

[0062] Referring to Figures 1 to 3 , in an embodiment of the present invention, the net cage 10 has a barrel-shaped structure, the top end of the net cage 10 is open and exposed above the sea surface, and a rotation center line (not marked) is provided along the axial direction of the net cage 10;

[0063] The boosting mechanism 30 includes a plurality of first boosting components 31, the first boosting components 31 are arranged on the outer peripheral surface of the net cage 10, and the plurality of first boosting components 31 are circumferentially spaced along the barrel-shaped structure, and are used to interact with environmental loads to generate a boosting force, so that the net cage 10 rotates around the rotation center line.

[0064] In the technical solution of an embodiment of the present invention, the axis direction of the cage 10 has a rotation center line. The first boosting assembly 31 is arranged on the outer peripheral surface of the cage 10. When an environmental load acts on the first boosting assembly 31, a tangential acting force will be applied to the outer peripheral surface of the cage 10, causing the cage 10 to rotate around the rotation center line. During the rotation of the netting 20 along with the cage 10, the attachment of marine organisms on the netting 20 can be reduced. The number of the first boosting assemblies 31 is several and they are arranged at intervals along the circumferential direction of the barrel-shaped structure, so that while the outer peripheral surface of the cage 10 can be subjected to the acting forces of environmental loads in various directions, the overall force on the cage 10 is more uniform, and the stability of the cage 10 during rotation is improved.

[0065] The top end of the cage 10 has an opening to facilitate putting in or catching cultured fish through the opening. The top end of the cage 10 needs to be higher than the sea surface to prevent the cultured fish from escaping from the culture space 11 through the opening.

[0066] Refer to Figure 10 , in an embodiment of the present invention, the first boosting assembly 31 includes:

[0067] A fixing member 311, the fixing member 311 is arranged on the outer peripheral surface of the cage 10, and a rotating shaft 312 is arranged at the outer end of the fixing member 311, and the rotating shaft 312 extends along the tangent direction of the outer peripheral surface of the cage 10; and

[0068] A propeller 313, the propeller 313 is rotatably sleeved on the rotating shaft 312.

[0069] In the technical solution of an embodiment of the present invention, the first boosting assembly 31 includes a fixing member 311 and a propeller 313. A rotating shaft 312 is arranged at the outer end of the fixing member 311, and the rotating shaft 312 extends along the tangent direction of the outer peripheral surface of the cage 10. The propeller 313 is rotatably sleeved on the rotating shaft 312. When an environmental load acts on the first boosting assembly 31, the propeller 313 rotates, and the connection part between the outer peripheral surface of the cage 10 and the first boosting assembly 31 is subjected to a tangential acting force, causing the cage 10 to rotate around the rotation center line.

[0070] Refer to Figure 10 , in an embodiment of the present invention, the fixing member 311 includes:

[0071] A fixing part 3111, the fixing part 3111 is arranged on the outer peripheral surface of the cage 10; and

[0072] A connecting part 3112, the connecting part 3112 has a head 31121 and a tail 31122 arranged back to back, the rotating shaft 312 is arranged at the tail 31122 so that the propeller 313 generates a power towards the head 31121, and the outer end of the fixing part 3111 is connected between the head 31121 and the tail 31122.

[0073] In the technical solution of an embodiment of the present invention, the fixing member 311 includes a fixing portion 3111 and a connecting portion 3112. One end of the fixing portion 3111 is connected to the outer peripheral surface of the cage 10, and the other end of the fixing portion 3111 is connected to the connecting portion 3112. The connecting portion 3112 has a head 31121 and a tail 31122 arranged back to back. The rotating shaft 312 is arranged at the tail 31122. When the propeller 313 is affected by environmental loads, the propeller 313 will rotate around the rotating shaft 312, so that the propeller 313 generates a power towards the head 31121. Since the connecting portion 3112 is connected to the outer peripheral surface of the cage 10 through the fixing portion 3111, when the propeller 313 rotates, the outer peripheral surface of the cage 10 is subjected to a tangential force, causing the cage 10 to rotate around the rotation center line. The connecting portion 3112 is integrally in a water droplet shape, and the head 31121 of the connecting portion 3112 is streamlined. The streamlined design reduces the resistance of the water flow to the head 31121 of the connecting portion 3112, thereby reducing the resistance suffered by the cage 10 during rotation and improving the self-rotation speed of the cage 10, and thus improving the efficiency of automatic cleaning of the cage 10.

[0074] Refer to Figures 1 to 3 , in an embodiment of the present invention, the heads 31121 of several of the first boosting assemblies 31 are all arranged in the clockwise direction, so that under the action of environmental loads, the cage 10 rotates around the rotation center line in the clockwise direction;

[0075] Or, the heads 31121 of several of the first boosting assemblies 31 are all arranged in the counterclockwise direction, so that under the action of environmental loads, the cage 10 rotates around the rotation center line in the counterclockwise direction.

[0076] In the technical solution of an embodiment of the present invention, the heads 31121 of all the first boosting assemblies 31 are arranged in the clockwise direction. When environmental loads act on several first boosting assemblies 31, the tangential forces exerted on the cage 10 by the several first boosting assemblies 31 connected to the cage 10 form a resultant force, causing the cage 10 to rotate around the rotation center line in the clockwise direction, improving the self-rotation speed of the cage 10, and thus improving the efficiency of automatic cleaning of the cage 10.

[0077] Or, the heads 31121 of all the first boosting assemblies 31 are arranged in the counterclockwise direction. When environmental loads act on several first boosting assemblies 31, the tangential forces exerted on the cage 10 by the several first boosting assemblies 31 connected to the cage 10 form a resultant force, causing the cage 10 to rotate around the rotation center line in the counterclockwise direction, improving the self-rotation speed of the cage 10, and thus improving the efficiency of automatic cleaning of the cage 10.

[0078] Refer to Figures 1 to 3, in an embodiment of the present invention, the cage 10 has a barrel-shaped structure. The top of the cage 10 is open and exposed above the sea surface, and there is a rotation center line along the axis direction of the cage 10;

[0079] The boosting mechanism 30 includes a plurality of second boosting components 32. The second boosting components 32 protrude from the bottom surface of the cage 10, and a plurality of the second boosting components 32 are arranged at intervals along the outer periphery of the bottom of the cage 10, and are used to interact with the environmental load to generate a boosting force, so that the cage 10 rotates around the rotation center line.

[0080] In the technical solution of an embodiment of the present invention, the second boosting components 32 are arranged on the bottom surface of the cage 10, and a plurality of the second boosting components 32 are arranged at intervals along the outer periphery of the bottom of the cage 10. When the environmental load acts on the plurality of second boosting components 32, the tangential acting forces applied to the outer periphery of the bottom of the cage 10 form a resultant force, so that the bottom of the cage 10 rotates around the rotation center line. During the rotation of the netting 20 along with the cage 10, the attachment of marine organisms on the netting 20 can be reduced. The number of the second boosting components 32 is several, and they are arranged at intervals on the bottom of the cage 10, so that while the bottom of the cage 10 can be subjected to the acting forces of environmental loads in all directions, the overall force on the cage 10 is more uniform, and the stability of the cage 10 during rotation is improved.

[0081] The structure of the second boosting component 32 is the same as that of the first boosting component 31, and the rotating shaft 312 of the second boosting component 32 is parallel to the bottom surface of the cage 10. The heads of a plurality of the second boosting components 32 are arranged in the clockwise direction, so that when the bottom surface of the cage 10 is subjected to the environmental load, it rotates around the rotation center line in the clockwise direction; or, the heads of a plurality of the second boosting components 32 are arranged in the counterclockwise direction, so that when the bottom surface of the cage 10 is subjected to the environmental load, it rotates around the rotation center line in the counterclockwise direction.

[0082] Refer to Figures 1 to 10 , in an embodiment of the present invention, the boosting mechanism 30 further includes a plurality of first boosting components 31. The first boosting components 31 are arranged on the outer peripheral surface of the cage 10, and a plurality of the first boosting components 31 are arranged at intervals along the circumferential direction of the barrel-shaped structure, and are used to interact with the environmental load to generate a boosting force, so that the cage 10 rotates around the rotation center line;

[0083] The cage 10 includes:

[0084] A bottom plate 13, the second boosting components 32 are arranged on the outside of the bottom plate 13, and the bottom plate 13 is provided with a plurality of the water passing holes 12; and

[0085] Side plate 14 is provided above the bottom plate 13 and extends along the outer peripheral edge of the bottom plate 13 to enclose the breeding space 11 with the bottom plate 13. The first boosting assembly 31 is provided outside the side plate 14. The side plate 14 can rotate relative to the bottom plate 13 around the rotation center line, and a plurality of water passing holes 12 are provided on the side plate 14.

[0086] In the technical solution of an embodiment of the present invention, the first boosting assembly 31 is provided outside the side plate 14, and the second boosting assembly 32 is provided outside the bottom plate 13. Environmental loads can act on the first boosting assembly 31 and the second boosting assembly 32 respectively, and generate acting forces to make the net cage 10 rotate around the rotation center line. In order to prevent the acting forces generated by the first boosting assembly 31 and the second boosting assembly 32 from being in opposite directions, resulting in a reduction in the resultant force received by the net cage 10, a decrease in the self-rotation rate of the net cage 10, and a decrease in the automatic cleaning efficiency of the net cage 10, the bottom plate 13 and the side plate 14 in the present invention can rotate relative to each other, and the rotations of the bottom plate 13 and the side plate 14 are not affected by each other, which improves the self-rotation rate of the net cage 10, thereby improving the automatic cleaning efficiency of the net cage 10.

[0087] In order to realize the function that the side plate 14 can rotate relative to the bottom plate 13 around the rotation center line, in an embodiment of the present solution, the self-rotating ocean ranch 100 further includes a support mechanism 40. The support mechanism 40 includes a first connection ring 41 and a second connection ring 42. The second connection ring 42 is located above the first connection ring 41. A first connecting member 43 is provided outside the first connection ring 41 and the second connection ring 42. The first connecting member 43 is connected to the first connection ring 41 and the second connection ring 42 respectively to fix the first connection ring 41 and the second connection ring 42. A second rotation groove (not labeled) is provided on the outer side of the bottom of the side plate 14. The structure of the second rotation groove is the same as that of the first rotation groove 14111. A third rotation groove (not labeled) is provided on the outer peripheral edge of the bottom plate 13. The structure of the third rotation groove is the same as that of the first rotation groove 14111. The first connection ring 41 is sleeved in the third rotation groove and can rotate relative to the bottom plate 13 around the rotation center line; the second connection ring 42 is sleeved in the second rotation groove and can rotate relative to the side plate 14 around the rotation center line. The structure of the second rotation groove is the same as that of the first rotation groove 14111. Among them, the support mechanism 40, the side plate 14 and the bottom plate 13 can all rotate independently. The support mechanism 40 is used to limit the relative displacement of the side plate 14 and the bottom plate 13 and enable the side plate 14 and the bottom plate 13 to independently rotate around the rotation center line.

[0088] The support mechanism 40 includes a plurality of support units (not shown), which are extended along the outer periphery of the cage 10, and the plurality of support units are connected end to end in sequence to assemble to form the support mechanism 40. The assembleable setting of the support mechanism 40 reduces the storage space of the support mechanism 40 and reduces the transportation cost of the support mechanism 40. At the same time, when the support mechanism 40 is damaged, the support unit corresponding to the damaged part can be replaced without replacing the entire support mechanism 40, thereby improving the maintenance efficiency of the support mechanism 40.

[0089] Reference Figures 1 to 10 In one embodiment of the present invention, the side panel 14 is divided into a plurality of enclosures 141 along the axial direction of the net box 10, the first booster assembly 31 is arranged on the outer side of the enclosure 141, each of the enclosures 141 can rotate around the rotation center line, and the enclosure 141 is provided with a plurality of water holes 12.

[0090] In the technical solution of an embodiment of the present invention, the side plate 14 is divided into a plurality of independently rotatable panels 141 along the axial direction, and the panels 141 are provided with water holes 12 and first booster assemblies 31. Since the water flow speeds at different depths in the ocean are different, in order to improve the utilization efficiency of the first booster assemblies 31 for the environmental loads at each depth, any two panels 141 can rotate relative to each other around the rotation centerline, and the rotation of each panel 141 is independent and not affected by the rotation of other panels 141, so as to avoid the mutual influence of the first booster assemblies 31 at each depth due to the excessive axial length of the cage 10, thereby improving the efficiency of automatic cleaning of the cage 10.

[0091] The enclosure 141 includes a plurality of enclosure units (not shown), which are extended along the outer periphery of the cage 10, and the plurality of enclosure units are connected end to end in sequence to assemble to form the enclosure 141. The assembleable arrangement of the enclosure 141 reduces the storage space of the enclosure 141 and reduces the transportation cost of the enclosure 141. At the same time, when the enclosure 141 is damaged, the enclosure unit corresponding to the damaged part can be replaced without replacing the entire enclosure 141, thereby improving the maintenance efficiency of the enclosure 141.

[0093] A top edge 1411, wherein the top edge 1411 is extended along the circumference of the net cage 10, and a first rotation groove 14111 is formed on a side of the top edge 1411 away from the breeding space 11; and

[0094] The bottom edge 1412 is located below the top edge 1411 and is arranged side by side with the top edge 1411. The bottom edge 1412 extends along the circumferential direction of the net cage 10. A second rotation groove is formed on the side of the bottom edge 1412 facing away from the aquaculture space 11. The first boosting assembly 31 is arranged between the top edge 1411 and the bottom edge 1412.

[0095] The self-rotating ocean ranch 100 further includes a connecting mechanism 50. The connecting mechanism 50 is located between two adjacent enclosure plates 141. The connecting mechanism 50 includes:

[0096] A first rotating ring 51, which is received in the first rotation groove 14111 and can rotate relative to the enclosure plate 141 around the rotation center line; and

[0097] A second rotating ring 52, which is stacked above the first rotating ring 51 and is fixedly connected to the first rotating ring 51. The second rotating ring 52 is received in the second rotation groove.

[0098] In the technical solution of an embodiment of the present invention, the enclosure plate 141 includes a top edge 1411 and a bottom edge 1412. A plurality of water passing holes 12 and a plurality of first boosting assemblies 31 are arranged between the top edge 1411 and the bottom edge 1412. The number of the connecting mechanisms 50 is several. The connecting mechanisms 50 are located between two adjacent enclosure plates 141 for connecting the two adjacent enclosure plates 141 and enabling the two adjacent enclosure plates 141 to rotate independently around the rotation center line. Among two adjacent enclosure plates 141, the bottom edge 1412 of the upper enclosure plate 141 has a second rotation groove, and the top edge 1411 of the lower enclosure plate 141 has a first rotation groove 14111. The connecting mechanism 50 includes a first rotating ring 51 and a second rotating ring 52. The first rotating ring 51 is sleeved in the first rotation groove 14111, and the inner side of the first rotating ring 51 abuts against the first rotation groove 14111. The second rotating ring 52 is sleeved in the second rotation groove, and the inner side of the second rotating ring 52 abuts against the second rotation groove. A second connecting member 53 is arranged on the outer sides of the first rotating ring 51 and the second rotating ring 52. The second connecting member 53 is respectively connected to the first rotating ring 51 and the second rotating ring 52 to fix the first rotating ring 51 and the second rotating ring 52. The connecting mechanism 50 is used for limiting the relative displacement of two adjacent enclosure plates 141 while enabling the two adjacent enclosure plates 141 to rotate independently around the rotation center line, so that the enclosure plates 141 at different depths can rotate independently. At the same time, the rotation of the enclosure plates 141 at different depths is not affected by other enclosure plates 141, improving the efficiency of automatic cleaning of the net cage 10.

[0099] The connecting mechanism 50 includes a number of connecting units (not labeled). The connecting units extend along the outer peripheral edge of the net cage 10, and the number of connecting units are connected end to end in sequence to assemble and form the connecting mechanism 50. The assemblable setting of the connecting mechanism 50 reduces the storage space of the connecting mechanism 50 and lowers the transportation cost of the connecting mechanism 50. At the same time, when the connecting mechanism 50 is damaged, the connecting unit at the corresponding damaged part can be replaced without replacing the entire connecting mechanism 50, improving the maintenance efficiency of the connecting mechanism 50.

[0100] Referring Figures 1 to 11 , in an embodiment of the present invention, the self-rotating ocean ranch 100 further includes a floating airbag 60. The floating airbag 60 is connected to the net cage 10 and is used to provide buoyancy for the net cage 10;

[0101] And / or, the self-rotating ocean ranch 100 further includes an anchor chain (not shown). One end of the anchor chain is connected to the net cage 10, and the other end of the anchor chain is fixed to the seabed;

[0102] And / or, the netting 20 includes a number of netting units 21. The netting units 21 are adapted to the water passing holes 12, and one netting unit 21 is detachably covered on one water passing hole 12.

[0103] In the technical solution of an embodiment of the present invention, the self-rotating ocean ranch 100 includes a floating airbag 60. The floating airbag 60 is arranged on the first connecting member 43 and the second connecting member 53, and the floating airbag 60 is fixed to the first connecting member 43 and the second connecting member 53 by a rope or a locking member. The floating airbag 60 can be inflated or deflated to adjust the depth of the net cage 10 submerged in the sea surface. When it is necessary to maintain the self-rotating ocean ranch 100, the floating airbag 60 is inflated to make the net cage 10 float out of the sea surface for maintaining the self-rotating ocean ranch 100. After the maintenance is completed, the floating airbag 60 is deflated. After the net cage 10 sinks to the preset depth, the floating airbag 60 is operated to make the net cage 10 in force balance and stable at the preset depth.

[0104] The self-rotating ocean ranch 100 further includes an anchor chain. One end of the anchor chain is fixed to the seabed, and the other end is fixed to the first connecting member 43 or the second connecting member 53, which is used to fix the net cage 10 to avoid economic losses caused by the net cage 10 drifting away due to the influence of complex water flows and other factors.

[0105] The netting 20 includes netting units 21. The netting units 21 are adapted to the water passing holes 12 and are detachably covered in the water passing holes 12. The netting unit 21 includes a frame body 211 and ropes 212. The frame body 211 is adapted to the water passing holes 12. The frame body 211 has a hollow part. The ropes 212 are woven in the hollow part of the frame body 211 and form the netting unit 21 with the frame body 211. When maintaining the net cage 10, when the netting unit 21 is damaged or the netting unit 21 is blocked by attachment of marine organisms, the maintenance of the netting 20 can be completed by quickly replacing the whole netting unit 21, which improves the maintenance efficiency of the netting 20. There is no need to take the whole netting 20 back to the shore for replacement, which reduces the maintenance cost of the netting 20.

[0106] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
