Description

Technical Field

[0001] This utility model relates to the breeding of aquatic animals, and in particular to a roller-type net cage that can easily remove organisms that are soiled by the netting. Background Technology

[0002] With the increasing scarcity of global fishery resources and the continuous squeeze on nearshore aquaculture space, expanding deep-sea aquaculture has become an important trend in fisheries development. Cage aquaculture, as an important component of modern fisheries, offers advantages such as improved aquaculture efficiency, reduced environmental pressure, and increased economic benefits. However, the netting, as a key component of the cage, is constantly immersed in seawater and is susceptible to fouling by marine organisms, primarily algae, shellfish, and barnacles. These fouling organisms not only increase the weight of the netting and affect the structural safety of the cage, but can also clog the mesh, hindering water exchange between the inside and outside of the cage, leading to oxygen deficiency and adversely affecting the growth of cultured organisms.

[0003] Currently, the main methods for cleaning seawater cage netting include manual cleaning, antifouling coating, mechanical cleaning, and cavitation jet cleaning. Among these, manual cleaning is the most traditional method, relying primarily on manpower or hand tools to remove deposits from the netting. While simple to operate, this method is labor-intensive, inefficient, and particularly difficult to implement for large, deep-sea cages, thus requiring regular manual replacement of the netting.

[0004] The antifouling coating method involves applying an antifouling coating to the netting to prevent the adhesion of fouling organisms. This method can reduce the degree of soiling of the netting to some extent, but the antifouling coating is expensive and has a limited lifespan. Therefore, like manual cleaning, the antifouling coating method requires regular manual replacement of the netting, increasing the labor intensity of workers.

[0005] Mechanical cleaning methods utilize mechanical equipment to clean netting, primarily including mechanical brush net washing machines, jet brush combination net washing machines, and high-pressure jet underwater net washing machines. For example, Chinese invention patent applications CN109848153A, CN116174401A, CN118341726A, CN118237328A, and CN113275295A disclose netting cleaning equipment used in mechanical cleaning methods. This method offers high cleaning efficiency, low labor intensity, and effective underwater cleaning of deep-sea net cages without replacing the netting. However, mechanical cleaning equipment can easily cause some damage to the netting, and the equipment cost is relatively high.

[0006] Cavitation jet cleaning is a novel net cleaning technology that utilizes microjets and shock waves generated by cavitation jets to clean fouling organisms from the netting. For example, Chinese patent specifications CN114904861B and CN210676110U disclose net cleaning equipment used in cavitation jet cleaning. This equipment can clean deep-sea net cages underwater without replacing the netting, offering high cleaning efficiency, minimal damage to the netting, and some environmental benefits. However, cavitation jet cleaning equipment is relatively complex and costly, and its application in China is still in its early stages.

[0007] Similar to the innovative concept of this patent application is the "Large Fish Farming Cage for Convenient Fishing and Net Cleaning" disclosed in the specification of Chinese Utility Model Patent CN206933018U, published on January 30, 2018. This cage includes a buoyancy chamber, uprights, a float frame, a bottom frame, a conical bottom net, side nets, and ropes. The buoyancy chamber is a circular or polygonal ring structure made of high-strength tubing with a large diameter. The buoyancy chamber is connected to several uprights, which in turn are connected to the float frame. During the farming process, the buoyancy provided by the inflated buoyancy chamber periodically raises the upper net above the water surface, allowing for the removal of attached organisms through sun exposure and rinsing, thus solving the problem of cleaning attached organisms from large net cages. However, this type of aquaculture cage only allows the net to be raised above the water surface for sun exposure and rinsing to remove fouling organisms; the fouling organisms attached to the lower part of the net, especially the bottom, remain unremoved.

[0008] Therefore, developing an aquaculture cage that can easily remove organisms from the netting without replacing it, and that is convenient, thorough, efficient, does not damage the netting, and is low-cost, is of great significance for ensuring aquaculture safety and improving aquaculture efficiency. Summary of the Invention

[0009] The purpose of this invention is to address the shortcomings of existing net cages in removing soiled organisms, such as incomplete removal, low efficiency, easy damage to the netting, and high equipment costs. This invention provides a roller-type net cage that offers convenient and thorough removal of soiled organisms, high efficiency, no damage to the netting, and low product cost.

[0010] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows: a roller-type mesh cage, comprising a mesh cover and a mesh cage frame, wherein the mesh cover is disposed on the mesh cage frame and a feeding window is provided on the mesh cover, characterized in that the mesh cage frame comprises several annular outer tubes, annular inner tubes, connecting tubes and connecting members, wherein the annular inner tubes are respectively connected to the inner side of the annular outer tubes through connecting members, and the connecting members are evenly distributed on the annular outer tubes and annular inner tubes; the annular outer tubes and annular inner tubes are both arranged radially and vertically, and adjacent annular outer tubes and annular inner tubes are distributed in parallel; the connecting tubes are respectively axially connected to the annular outer tubes and annular inner tubes through connecting members. The components are assembled to form a roller-type net cage frame; the connecting pipe is closed at both ends and has an internal cavity that also serves as a float; buoyancy adjustment and balancing devices are respectively provided on the outer and inner annular pipes, which position the net cage in a semi-submerged position in the aquaculture water area and maintain its balance; water buckets are respectively provided between the outer and inner annular pipes to promote the net cage's circumferential rotation; first anchoring devices are respectively provided at both ends of the net cage frame, which axially fix the net cage and ensure its free circumferential rotation; second anchoring devices are respectively provided on the outer side of the net cage frame, which laterally fix the net cage and prevent it from rotating circumferentially.

[0011] Preferably, the buoyancy adjustment and balancing device includes several water inlet pipes and air outlet pipes. The water inlet pipes and air outlet pipes are respectively installed on the outer annular pipe and the inner annular pipe, and the water inlet pipes and air outlet pipes are respectively connected to the inner cavities of the outer annular pipe and the inner annular pipe. Removable sealing plugs are matched on the water inlet pipes and air outlet pipes respectively.

[0012] Preferably, each water bucket includes a cylindrical bucket body with an open water cavity inside the bucket body and symmetrical grooves on the outer side of the bucket body. The water buckets are respectively fitted between the annular outer tube and the annular inner tube through the grooves. Clamping members are respectively provided on the annular outer tube and the annular inner tube, and the connecting end of the clamping member is detachably connected to the water bucket.

[0013] Preferably, the water buckets disposed between the outer annular pipe and the inner annular pipe are evenly arranged.

[0014] Preferably, each of the first anchoring devices includes a plurality of first anchor chains, a first fixed anchor, and a connecting swivel. One end of the connecting swivel is connected to the connectors at both ends of the cage frame via the first anchor chains, and the other end of the connecting swivel is connected to the first fixed anchor via the first anchor chains.

[0015] Preferably, the second anchoring device includes a plurality of second anchor chains and second fixed anchors, one end of the second anchor chain being detachably connected to a connector located outside the cage frame, and the other end of the second anchor chain being connected to the second fixed anchor.

[0016] Compared with existing technologies, this utility model has the following advantages: The annular outer tube, annular inner tube, and connecting tube used in this utility model are strongly connected and combined into a roller-type net cage frame through connectors. The net is set on the net cage frame, thus forming an aquaculture net cage. The closed ends of the connecting tube ensure that the connecting tube always maintains a certain buoyancy; the buoyancy adjustment and balancing devices respectively provided on the annular outer tube and annular inner tube position the net cage in the aquaculture water area at a semi-submersible position that meets the design requirements, and the net cage can always maintain a balanced state with the rise and fall of the waves under the action of the buoyancy adjustment and balancing devices. The net cage in the semi-submersible position in the aquaculture water area has its part below the water surface used for aquaculture, while the part above the water surface can remove algae and fouling organisms from the net through sun exposure. Shellfish and barnacle fouling organisms can be transformed into organic food for the aquaculture objects through sun exposure or removed by rinsing, making the removal of fouling organisms convenient. The cleaning of fouling organisms on the net is carried out above the water surface, without the need to replace the net, which has high cleaning efficiency and does not damage the net. The water bucket between the outer and inner annular pipes allows the net cage to rotate circumferentially under the influence of ocean currents. This rotation ensures that all the netting is thoroughly exposed to sunlight, removing all fouling organisms. The first anchoring device axially secures the net cage, while the second anchoring device laterally secures it, making it easy to determine the areas of the netting exposed to sunlight. This invention uses few components and has low product cost. Attached Figure Description

Detailed Implementation

[0025] In the description of the embodiments below, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, some technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0026] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0027] The connection method can be any existing connection method, such as heat fusion connection, screw connection, bolt connection, etc., depending on the actual needs.

[0028] exist Figures 1-6 This embodiment provides a roller-type net cage, which solves the problems of inconvenient operation, incomplete cleaning, low cleaning efficiency, easy damage to the net, and high equipment cost in the existing net cages for removing organisms that are soiled on the net.

[0029] exist Figure 1 Among them, a roller-type wire mesh cage includes a wire mesh 1 and a wire mesh cage frame 2, with the wire mesh 1 disposed on the wire mesh cage frame 2.

[0030] like Figure 1As shown, a feeding window 3 is provided on the net 1. During the aquaculture process, feed can be given through the feeding window 3, and fish can also enter the net cage through the feeding window 3 for rearing and harvesting. Of course, for rearing and harvesting, a harvesting window can also be provided on the net, depending on the aquaculture species.

[0031] exist Figure 1 , Figure 2 and Figure 3 In the middle, the cage frame 2 includes several annular outer tubes 201, annular inner tubes 202, connecting tubes 203 and connectors 204. The number of annular outer tubes 201, annular inner tubes 202, connecting tubes 203 and connectors 204 can be determined according to the scale of aquaculture, the conditions of aquaculture water area and design requirements.

[0032] like Figure 1 , Figure 2 , Figure 3 As shown, the inner annular tube 202 is connected to the inner side of the outer annular tube 201 by connectors 204, and the connectors 204 are evenly arranged on the outer annular tube 201 and the inner annular tube 202.

[0033] exist Figure 1 , Figure 3 In this design, both the annular outer tube 201 and the annular inner tube 202 are arranged radially and vertically, and adjacent annular outer tubes 201 and adjacent annular inner tubes 202 are distributed in parallel. Connecting pipes 203 are axially connected between the annular outer tube 201 and the annular inner tube 202 through connecting parts 204.

[0034] The annular outer tube 201 and the annular inner tube 202 can be made of low-density polyethylene pipe or stainless steel pipe resistant to seawater corrosion. In this embodiment, the annular outer tube 201 and the annular inner tube 202 are preferably made of low-density polyethylene pipe and formed into an annular shape by bending and hot-melt welding.

[0035] The connecting pipe 203 can be made of low-density polyethylene or stainless steel that is resistant to seawater corrosion. In this embodiment, low-density polyethylene is preferred as the connecting pipe 203.

[0036] like Figure 3 As shown, both ends of the connecting pipe 203 are sealed by pipe caps, and the interior of the connecting pipe 203 has a cavity that also serves as a float. Therefore, the connecting pipe 203 can provide buoyancy for the cage.

[0037] The connector 204 can be formed by symmetrically welding two commercially available tee fittings and one four-way fitting together at high temperature. The two tee fittings are respectively connected to the outer annular pipe 201 and the inner annular pipe 202, and the axis of the four-way fitting is directly connected to the connecting pipe 203. Alternatively, the connector 204 can also be other publicly available or commercially available structural connectors.

[0038] It should be noted that, in this embodiment, the connector 204 preferably adopts the "a frame-type aquaculture cage connector" disclosed in the specification of Chinese Utility Model Patent CN215819658U, which was applied for by the applicant and authorized on February 15, 2022. The connector includes two detachably connected connector bodies, and at least one first fixing through hole is provided on the mating surface of the two connector bodies; a pressing plate is detachably connected to the side end face of the two connector bodies, and a second fixing through hole is provided on the pressing surface of the pressing plate and the connector body; the axes of the first and second fixing through holes are perpendicular to each other.

[0039] like Figure 1 As shown, the first fixing through hole can be used to encircle and fix the annular outer tube 201 and the annular inner tube 202, and the second fixing through hole opened on the mating surface of the pressing plate and the connector body can be used to encircle and fix the connecting tube 203. The radially vertically arranged annular outer tube 201 and annular inner tube 202 and the axially arranged connecting tube 203 are strongly connected and combined to form a roller-type net cage frame 2 by the connector 204. When applied in aquaculture waters, the roller-type net cage frame is placed horizontally, and the net 1 is connected to the inside of the net cage frame 2 or covers the outside of the net cage frame 2, thereby forming a roller-type net cage.

[0040] exist Figure 1 , Figure 2 In the process, buoyancy adjustment and balancing devices 4 are respectively installed on the outer annular tube 201 and the inner annular tube 202. The buoyancy adjustment and balancing devices 4 position the net cage in a semi-submerged position in the aquaculture water area and maintain its balance.

[0041] Further explanation is needed, such as Figure 4 As shown, the buoyancy adjustment and balancing device 4 includes several inlet pipes 401 and outlet pipes 402. The inlet pipes 401 and outlet pipes 402 are respectively installed on the annular outer pipe 201, and are connected to the inner cavity of the annular outer pipe 201. Similarly, the inlet pipes 401 and outlet pipes 402 are also respectively installed on the annular inner pipe 202, and are connected to the inner cavity of the annular inner pipe 202. Removable sealing plugs 403 are fitted onto the inlet pipes 401 and outlet pipes 402 respectively.

[0042] In this embodiment, the amount of water to be injected into the annular outer pipe 201 and annular inner pipe 202 is calculated in advance based on the semi-submerged position of the net cage in the aquaculture area and the aquaculture requirements. Then, water is injected into the annular outer pipe 201 and annular inner pipe 202 through the inlet pipe 401 according to the preset water volume. Simultaneously with water injection, air inside the annular outer pipe 201 and annular inner pipe 202 is discharged through the vent pipe 402. The inlet pipe 401 and vent pipe 402 are then sealed using a sealing plug 403, which conveniently adjusts the buoyancy generated within the annular outer pipe 201 and annular inner pipe 202, thereby ensuring the net cage is in the semi-submerged position required for aquaculture. Because the water is mobile within the annular outer pipe 201 and annular inner pipe 202, based on the principles of communicating vessels and fluid balance, the net cage can rise and fall with the waves while maintaining a balanced state.

[0043] exist Figure 2 In the middle, water buckets 5 are respectively installed between the annular outer pipe 201 and the annular inner pipe 202. These water buckets 5 are like water buckets on a waterwheel, and under the action of ocean currents, they cause the net cage to rotate circumferentially.

[0044] It needs further explanation that, in order to achieve a reliable connection between the water tank 5 and the annular outer pipe 201 and the annular inner pipe 202, such as Figure 5 As shown, each water bucket 5 includes a cylindrical bucket body 501. The inside of the bucket body 501 has an open water cavity 502. Symmetrical grooves 503 are formed on the outer side of the bucket body 501. The water bucket 5 is fitted into the annular outer tube 201 and the annular inner tube 202 respectively through these grooves 503. Clamping connectors 6 are respectively provided on the annular outer tube 201 and the annular inner tube 202. The connecting ends of the clamping connectors 6 are detachably connected to the water bucket 5 via connectors. The connectors used can be set screws or connecting bolts made of stainless steel resistant to seawater corrosion.

[0045] It needs further explanation that, in order to make the thrust generated by the water jets cause the net cage to rotate evenly, such as Figure 2 As shown, the water buckets 5 set between the annular outer pipe 201 and the annular inner pipe 202 are evenly arranged.

[0046] exist Figure 1 In the structure, a first anchoring device 7 is provided at each end of the wire mesh cage frame 2. The first anchoring device 7 axially fixes the wire mesh cage and ensures that the wire mesh cage can rotate freely in the circumferential direction. A second anchoring device 8 is provided on the outside of the wire mesh cage frame 2. The second anchoring device 8 laterally fixes the wire mesh cage and prevents the wire mesh cage from rotating in the circumferential direction.

[0047] Further explanation is needed, such as Figure 6As shown, each of the first anchoring devices 7 includes several first anchor chains 701, first fixed anchors 702 and a connecting ring 703. One end of the connecting ring 703 is connected to the connectors 204 located at both ends of the cage frame 2 through the first anchor chains 701, and the other end of the connecting ring 703 is connected to the first fixed anchors 702 through the first anchor chains 701.

[0048] Its connecting ring 703 consists of two connecting rings and a rotating shaft. The rotating shaft is rotatably connected to the two connecting rings, and a limiting platform is fixedly connected to both ends of the rotating shaft. The limiting platform can prevent the rotating shaft from detaching from the connecting rings.

[0049] Further explanation is needed, such as Figure 1 As shown, the second anchoring device 8 includes a plurality of second anchor chains 801 and second fixed anchors 802, wherein one end of the second anchor chain 801 is detachably connected to the connector 204 located outside the cage frame 2, and the other end of the second anchor chain 801 is connected to the second fixed anchor 802.

[0050] Both the first anchor chain 701 and the second anchor chain 801 are conventional anchor chains, such as anchor ropes and iron chains. Both the first fixed anchor 702 and the second fixed anchor 802 are conventional anchors, such as mast anchors, mastless anchors, and high-holding-force anchors. The anchor chains and fixed anchors can be selected based on factors such as the conditions of the aquaculture waters and aquaculture requirements.

[0051] In this embodiment, the connector 204 preferably adopts the "Frame-type Aquaculture Net Cage Connector" disclosed in the specification of Chinese Utility Model Patent CN215819658U, which was applied for by the applicant and authorized on February 15, 2022. The connector has rope grooves on the mating surfaces of the two connector bodies, and first rope holes connecting its two end faces to the rope grooves on the mating surfaces of the two connector bodies. Second rope holes connecting the rope grooves are provided on the outer surfaces of the two connector bodies. As can be seen from the design of the rope hole positions on the connector, the first anchor chain 701 is connected to the first rope hole, meaning that the connection position of the first anchor chain 701 with the connector 204 is at the end of the connector, thus achieving axial fixation of the net cage. The second anchor chain 801 is detachably connected to the second rope hole, meaning that the connection position of the second anchor chain 801 with the connector 204 is on the outer surface of the connector, thus achieving lateral fixation of the net cage.

[0052] The net cage twists under the action of waves and rotates circumferentially under the action of water jets. Because the connecting swivel 703 itself rotates, it ensures that the first anchor chains 701 do not become kinked, thus guaranteeing the free circumferential rotation of the net cage. After the net cage rotates to a certain angle, the second anchor chain 801, in cooperation with the connector 204, laterally fixes the net cage and prevents its free circumferential rotation, thereby determining the exposed portion of the netting above the water surface.

[0053] This utility model's roller-type net cage, through the inlet pipe 401 and outlet pipe 402 of the buoyancy adjustment and balance device 4 on the annular outer pipe 201 and annular inner pipe 202, can be positioned in a semi-submerged position in the aquaculture water area. A large portion of the net cage is below the water surface, while a small portion is above. The submerged portion is used for aquaculture, while the above-water portion can be exposed to sunlight to remove algae and other debris from the netting 1. Some of the algae and debris can fall into the water and become food for the farmed fish. Shellfish and barnacle debris, which do not form hard shells quickly due to sun exposure, can be removed by rinsing. Alternatively, after sun exposure, the netting can be submerged, where the hardened shells of shellfish and barnacles can become organic food for the farmed fish. The removal of debris is convenient. Cleaning the netting 1 is done above the water surface, eliminating the need to replace the netting. This method is convenient, efficient, and does not damage the netting 1. The water bucket 5 located between the annular outer pipe 201 and the annular inner pipe 201 allows the net cage to rotate circumferentially under the action of ocean currents, without human intervention. This circumferential rotation allows all the netting 1 to be exposed to sunlight, removing fouling organisms easily and thoroughly. The first anchoring device 7 axially fixes the net cage and ensures its free circumferential rotation; the second anchoring device 8 laterally fixes the net cage and prevents its circumferential rotation, making it easy to determine the sun-exposed areas of the netting. This invention uses few components, resulting in low product cost. Furthermore, the rotation of the net cage itself stirs up sediment such as feed residue and feces accumulated at the bottom of the cage, allowing it to escape through the mesh of the netting, thus improving the aquaculture environment inside the net cage. Additionally, when exposing the netting 1 above the water surface to sunlight, any damage can be visually inspected and easily repaired.

[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
