Description

Technical Field

[0001] This invention relates to the field of aquaculture equipment technology, and particularly to marine aquaculture cage modules and cages. Background Technology

[0002] Traditional marine aquaculture cages mainly rely on platforms built with buoys and templates. The buoys are connected by ropes to form a cage frame. Fishing nets are placed in the frame so that aquaculture can be carried out in the nets. In addition, wooden boards are fixed to the upper end of the buoys for fishermen to walk on, such as the cage involved in patent CN102239817A.

[0003] This traditional net cage requires too many parts to install and disassemble when fishermen migrate seasonally, and the flexible connection between the buoys makes the buoys too free, making it unstable for fishermen to walk on top of the buoys. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a marine aquaculture cage module that is easy to install and disassemble, and makes the assembled cage more stable.

[0005] The present invention also proposes a net cage having the above-mentioned marine aquaculture net cage module.

[0006] According to a first aspect of the present invention, a marine aquaculture cage module includes a transfer buoy, an extension buoy, a drive component, a hook, and an unlocking component. Both the transfer buoy and the extension buoy include an upper cavity and a lower cavity. The upper cavity is rectangular, and the lower cavity narrows from top to bottom. Both the extension buoy and the transfer buoy have a male connector at one end along their length. The extension buoy has a first female connector at the other end along its length, and the transfer buoy has a second female connector at one end along its width. The inner walls of both the first and second female connectors are provided with first hooks. The male connector is slidably connected to a second hook. The second hook is connected to the male connector via a first elastic element. The first elastic element drives the second hook to retract into the male connector, and the male connector is used to insert the first hook. A female head or a second female head is provided to allow the second hook to connect to the corresponding first hook. A driving component is located inside the male head and is connected to the second hook. The driving component is used to drive the second hook to extend. When the male head is inserted into the corresponding first or second female head, the first hook can press the second hook into the male head. Both the hook adapter float and the extension float are provided with threaded connection holes. The hook is threaded into the threaded connection holes and is used to hang the aquaculture net. An unlocking component is located on the male head and is connected to the driving component. The unlocking component is used to release the driving component from the second hook, causing the second hook to retract.

[0007] It has at least the following beneficial effects: The connecting buoys and extension buoys are connected by a male connector and either a first or second female connector to form a net cage. A second hook secures the first hook, making the connection convenient and quick, requiring only a plug-in connection. Furthermore, the connection of the male connector to the first and second female connectors allows adjacent connecting buoys and extension buoys to be spliced ​​end-to-end, increasing the stability of the entire net cage frame and reducing the degree of freedom between adjacent net cages. The second hook can also extend elastically, allowing for easy and quick fixing of adjacent connecting buoys and extension buoys during connection. This makes it suitable for fishermen to relocate according to their aquaculture needs, and facilitates installation and dismantling.

[0008] According to some embodiments of the present invention, the second hook has an inclined surface at one end near the driving member. The driving member includes a rotor and a second elastic member. The rotor is rotatably connected inside the male head, and the rotation axis of the rotor extends along the axial direction of the male head. A driving protrusion is provided on the outer peripheral wall of the rotor, and the driving protrusion abuts against the inclined surface. The second elastic member is connected between the rotor and the male head. The second elastic member drives the rotor to rotate, causing the driving protrusion to push against the inclined surface, thereby causing the second hook to extend out of the male head.

[0009] According to some embodiments of the present invention, a plurality of driving protrusions are provided, and the plurality of driving protrusions are evenly distributed around the male head in the circumference. The second hook is provided in a one-to-one correspondence with the driving protrusions, and the first hook is provided in a one-to-one correspondence with the second hook.

[0010] According to some embodiments of the present invention, the unlocking element includes a button that is eccentrically hinged to the rotor. The button is capable of driving the rotor to rotate, causing the driving protrusion to disengage from the inclined surface, thereby causing the second hook to retract into the male head.

[0011] According to some embodiments of the present invention, a float plate is also included, and a groove is provided on the outer peripheral wall of the upper cavity, in which the float plate is engaged.

[0012] According to some embodiments of the present invention, the male head, the first female head, and the second female head are all disposed on the upper cavity, and the male head, the first female head, and the second female head are all disposed above the float plate.

[0013] According to some embodiments of the present invention, the upper ends of both the transfer pontoon and the extension pontoon are provided with anti-slip structures.

[0014] According to some embodiments of the present invention, a waterproof ring is provided on the male head, and a receiving groove is provided on the inner wall of both the first female head and the second female head. When the male head is inserted into the corresponding first female head or second female head, the waterproof ring is engaged in the receiving groove.

[0015] According to some embodiments of the present invention, an anchoring structure is provided on the side of the upper cavity away from the hook.

[0016] According to a second aspect of the present invention, a net cage includes a marine aquaculture net cage module according to the first aspect of the present invention, wherein a transition buoy and an extension buoy are connected end to end to form a rectangular frame; a net is housed in the rectangular frame, and a plurality of buckles are provided around the net, the buckles being used to fasten corresponding hooks.

[0017] It has at least the following beneficial effects: This cage has all the beneficial effects brought about by the above-mentioned marine aquaculture cage module, which will not be repeated here.

[0018] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0021] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0022] In the description of this invention, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0023] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0024] Reference Figures 1 to 8 This invention discloses a marine aquaculture cage module, including a transition float 100a, an extension float 100b, a drive unit 200, a hook 300, and an unlocking unit 400. Both the transition float 100a and the extension float 100b include an upper cavity 110 and a lower cavity 120. The upper cavity 110 is rectangular, and the lower cavity 120 narrows from top to bottom. To maintain stability in the water, the lower cavity 120 is designed with a narrowing shape, shifting the center of gravity upwards and directing the water pressure on the lower cavity 120 as much as possible towards its outer wall, reducing lateral instability. Similar to the pointed arc shape of a ship's bottom, the cross-section of the lower cavity 120 perpendicular to the front-back direction can be cylindrical, triangular, or a pointed arc. The extension pontoon 100b is a module mainly used to splice cages, while the adapter pontoon 100a is a module used to make a turning connection when the extension pontoon 100b needs to turn 90°. The two modules are actually the same in shape, length, width and height, except that the female interface of the adapter pontoon 100a is opened on the side (to achieve a 90° turning connection).

[0025] Refer to 1 to Figure 4Both the extension float 100b and the adapter float 100a have a male connector 130 at one end along their length, and a first female connector 140a at the other end along their length. The adapter float 100a has a second female connector 140b at one end along its width. The inner walls of both the first and second female connectors 140a and 140b are provided with first hooks 141. The male connector 130 is slidably connected to the second hook 131. The second hook 131 is connected to the male connector 130 via a first elastic element 132. The first elastic element 132 drives the second hook 131 to retract into the male connector 130. The male connector 130 is used to insert into either the first or second female connector 140a, so that the second hook 131 connects to the corresponding first hook 141. The so-called first and second female connectors 140a and 140b are actually female connector slots, mainly for accommodating the insertion of the male connector 130 to achieve the connection function.

[0026] Reference Figures 4 to 7 The driving component 200 is disposed within the male connector 130 and is connected to the second hook 131. The driving component 200 drives the second hook 131 to extend. When the male connector 130 is inserted into the corresponding first female connector 140a or second female connector 140b, the first hook 141 can press the second hook 131 into the male connector 130, meaning the male connector 130 can be directly inserted into the corresponding first female connector 140a or second female connector 140b, and the second hook 131 can automatically extend. The first hook 141 is fastened to achieve a stable connection; the hook 300 is provided with threaded connection holes 140 on both the transfer float 100a and the extension float 100b, and the hook 300 is threaded into the threaded connection holes 140. The hook 300 is used to hang the aquaculture net; the unlocking part 400 is provided on the male head 130, and the unlocking part 400 is connected to the drive part 200. The unlocking part 400 is used to release the drive part 200 from driving the second hook 131, so that the second hook 131 retracts.

[0027] It should be understood that the connecting buoy 100a and the extension buoy 100b are connected by the male connector 130 and the first female connector 140a or the second female connector 140b to form a net cage. The second hook 131 is used to fasten the first hook 141, which is convenient and allows the connecting buoy 100a and the extension buoy 100b to be connected quickly, requiring only plugging. After the male connector 130 is connected to the first female connector 140a and the second female connector 140b, adjacent connecting buoys 100a and extension buoys 100b can be spliced ​​end to end, making the frame of the entire net cage more stable and reducing the degree of freedom between adjacent net cages. The second hook 131 can extend elastically, and during connection, only plugging is required to fix adjacent connecting buoys 100a and extension buoys 100b, which is convenient and quick, suitable for fishermen to relocate according to aquaculture needs, and easy to install and dismantle.

[0028] In some embodiments, the male connector 130 is detachably connected to the upper cavity 110, and a cover plate is provided at the upper end of the upper cavity 110. An anti-slip structure 150 is provided at the upper end of the cover plate, allowing the transfer float 100a and the extension float 100b to overlap for transport after the cover plate is removed, saving space. The male connector 130 can be connected to the upper cavity 110 by screwing it in.

[0029] Reference Figure 4 and Figure 5 The second hook 131 has a slope 131a at one end near the drive member 200. The drive member 200 includes a rotor 210 and a second elastic member 220. The rotor 210 is rotatably connected inside the male head 130, and the rotation axis of the rotor 210 extends along the axial direction of the male head 130. A drive protrusion 211 is provided on the outer peripheral wall of the rotor 210, and the drive protrusion 211 abuts against the slope 131a. The second elastic member 220 is connected between the rotor 210 and the male head, and the second elastic member 220 drives the rotor 210 to rotate, causing the drive protrusion to... 211 pushes the inclined surface 131a, thereby causing the second hook 131 to extend out of the male head 130. It can be understood that when the rotor 210 rotates, it relies on the driving protrusion 211 to push the inclined surface 131a, thereby driving the second hook 131 to extend. The second hook 131 is provided on all four walls of the male head 130. Setting several second hooks 131 can ensure the stability of the connection. Moreover, this rotor 210 driving method is simpler. The second hook 131 can be driven by the driving protrusion 211, which is convenient for fishermen to use.

[0030] In some embodiments, a plurality of driving protrusions 211 are provided, and the plurality of driving protrusions 211 are evenly distributed around the male head 130 in the circumference. The second hook 131 is provided in a one-to-one correspondence with the driving protrusions 211, and the first hook 141 is provided in a one-to-one correspondence with the second hook 131.

[0031] Reference Figure 7The unlocking component 400 includes a button eccentrically hinged to the rotor 210. The button drives the rotor 210 to rotate, causing the driving protrusion 211 to disengage from the inclined surface 131a, thereby retracting the second hook 131 into the male head 130. It can be understood that because the unlocking component 400 is eccentrically hinged to the rotor 210, pressing the unlocking component 400 drives the rotor 210 to rotate. The rotation of the rotor 210 causes the driving protrusion 211 to disengage from the inclined surface 131a, and the second hook 131 retracts into the male head 130 under the action of the first elastic member 132, thus disengaging the second hook 131 from the first hook 141 and unlocking the device. Furthermore, the male head 130 is prism-shaped, preventing it from rotating within the corresponding female head, thereby limiting rotation between the extension float 100b and between the extension float 100b and the adapter float 100a, further improving connection stability and safety during use.

[0032] Reference Figure 5 It also includes a float plate 500, and the outer peripheral wall of the upper cavity 110 is provided with a slot 111, in which the float plate 500 is engaged. It can be understood that the float plate 500 can increase the contact area between the corresponding extended float 100b or transition float 100a and the water surface, thereby increasing the buoyancy distribution range of the corresponding extended float 100b or transition float 100a in the water, resulting in better stability of the extended float 100b and transition float 100a in the water.

[0033] In some embodiments, the male connector 130, the first female connector 140a, and the second female connector 140b are all disposed on the upper cavity 110, and are all disposed above the float plate 500. It is understood that the float plate 500 not only serves as a component to stabilize the extension float 100b and the transition float 100a in the water, but also as a partition separating the water surface from the connection point, preventing the male connector 130, the first female connector 140a, and the second female connector 140b from contacting seawater, thereby improving the service life of the male connector 130, the first female connector 140a, and the second female connector 140b at the connection point.

[0034] In some embodiments, the upper ends of the transfer buoy 100a and the extension buoy 100b are provided with anti-slip structures 150. It is understood that the anti-slip structures 150 enable fishermen to walk directly on them without slipping, thus improving safety. Furthermore, because the present invention adopts this method of directly connecting the transfer buoy 100a and the extension buoy 100b, the trouble of laying wooden planks is eliminated, reducing the difficulty of operation for fishermen.

[0035] In some embodiments, the male connector 130 is provided with a waterproof ring 133, and the inner walls of the first female connector 140a and the second female connector 140b are both provided with receiving grooves 142. When the male connector 130 is inserted into the corresponding first female connector 140a or second female connector 140b, the waterproof ring 133 is engaged in the receiving groove 142. The waterproof ring 133 and the receiving groove 142 cooperate with each other to waterproof the connection between the male connector 130 and the first female connector 140a and the second female connector 140b, thereby reducing the problem of water corrosion at the connection.

[0036] In some embodiments, an anchoring structure 600 is provided on the side of the upper cavity 110 away from the hook 300. The anchoring structure 600 can fix the net cage when the net cage frame is built, ensuring the stability of the net cage in the water and preventing the net cage from being blown away by waves or wind.

[0037] The present invention also discloses a net cage, comprising a marine aquaculture net cage module according to the present invention, wherein a transition float 100a and an extension float 100b are connected end to end to form a rectangular frame; a net 700 is housed in the rectangular frame, and a plurality of buckles 710 are provided around the net 700, the buckles 710 being used to fasten the corresponding hooks 300.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
