Description

Technical Field

[0001] This utility model relates to the field of marine aquaculture equipment technology, specifically to a multifunctional mobile net cage for marine aquaculture. Background Technology

[0002] With the increasing global demand for the sustainable use of marine fishery resources and the advancement of aquaculture technology, the marine aquaculture industry has gradually developed from small-scale nearshore aquaculture to large-scale and intensive offshore aquaculture. As one of the important forms of marine aquaculture, net cage culture is widely used for the large-scale cultivation of aquatic products such as shellfish, fish and crustaceans due to its flexible structure, controllable cost and easy management. However, existing marine aquaculture net cages still face many technical bottlenecks in practical applications, which seriously restrict aquaculture efficiency and economics. Traditional net cages need to be lifted as a whole when harvesting, which is time-consuming and labor-intensive if the net cage is large or the water is deep. After the net cage is lifted, it is in a suspended state, and the platform moves up and down with the waves, causing the net cage to sway, which poses a safety hazard.

[0003] Therefore, there is a need for a mobile marine aquaculture cage that is depth-adjustable, easy to catch, reliable to lock, and secure to limit movement. Utility Model Content

[0004] This invention aims to solve the above-mentioned technical problems by providing a multifunctional mobile net cage for marine aquaculture.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a multifunctional marine aquaculture mobile cage, including a support ring; a cage frame with a ring-shaped frame structure is fixedly connected to the bottom of the support ring; a mesh plate is fixedly connected between the cage bones of the cage frame, and the mesh plate encloses to form an aquaculture cavity; the cage frame has a bottom frame that can move up and down in a vertical direction inside; a number of support columns for installing limiting mechanisms are fixedly connected at equal intervals to the top of the support ring; and a beam frame erected above the support ring is fixedly connected between the tops of the support columns.

[0006] As a preferred embodiment of this utility model, a winding machine is fixedly connected to the top of the beam frame; a cable is wound around the winding wheel of the winding machine; the bottom end of the cable is fixedly connected to the bottom frame and is used to drive the bottom frame to move up and down.

[0007] As a preferred embodiment of this utility model, the bottom of the support ring is fixedly connected with a number of floats at equal intervals to provide buoyancy.

[0008] As a preferred embodiment of this utility model, the limiting mechanism on the support column includes a mounting block fixedly installed in the middle of the support column; a trapezoidal limiting block that can move radially along the support column is provided on the side of the mounting block near the radially inner side of the support ring; the inclined surface of the trapezoidal limiting block faces the radially inner side of the support ring and downwards; a guide rod is fixedly connected to the side of the trapezoidal limiting block near the mounting block; the guide rod is inserted into the mounting block; and a connecting plate is fixedly connected to the end of the guide rod away from the trapezoidal limiting block.

[0009] As a preferred embodiment of this utility model, an L-shaped clamping plate is rotatably connected to the side of the mounting block away from the trapezoidal limiting block; a spring is sleeved on the rod segment of the guide rod located between the mounting block and the connecting plate; the two ends of the spring are fixedly connected to the mounting block and the connecting plate respectively; the L-shaped clamping plate is used to restrict the axial disengagement of the guide rod.

[0010] The present invention has the following advantages: by driving the cable to wind and unwind by a winding machine, the up and down movement of the bottom frame can be precisely controlled, and the internal space of the net cage can be dynamically adjusted; during the harvesting process, it is only necessary to pull up the bottom frame by the winding machine to gather the aquatic products inside, without lifting the entire net cage, and the net cage is always fixed at the target water layer during the operation to avoid the risk of shaking.

They 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, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please refer to the following: Figure 1-4 This utility model discloses a multifunctional mobile net cage for marine aquaculture, including a support ring 1, a cage frame 3 fixedly connected to the bottom of the support ring 1, a mesh plate 4 fixedly connected between the cage bones of the cage frame 3, a bottom frame 5 that can move up and down inside the cage frame 3, and a number of support columns 7 with limiting mechanisms fixedly connected at equal intervals to the top of the support ring 1, and a number of beam frames 8 erected above the support ring 1 fixedly connected between the tops of the support columns 7.

[0017] A winding machine 9 is fixedly connected to the top of the beam frame 8. A cable 6 is connected to the winding wheel of the winding machine 9. The bottom of the cable 6 is fixedly connected to the bottom frame 5. Several floats 2 are fixedly connected at equal intervals to the bottom of the support ring 1. The limiting mechanism on the support column 7 includes a mounting block 10 fixedly installed in the middle of the support column 7. A movable trapezoidal limiting block 12 is provided on the side of the mounting block 10 near the inside of the support ring 1. The inclined surface of the trapezoidal limiting block 12 faces the inside and below of the support ring 1. A guide rod 11 that is inserted into the mounting block 10 is fixedly connected to the side of the trapezoidal limiting block 12 near the mounting block 10. A connecting plate 13 is fixedly connected to the end of the guide rod 11 away from the trapezoidal limiting block 12. An L-shaped clamping plate 14 is rotatably connected to the side of the mounting block 10 away from the trapezoidal limiting block 12. A spring 15 is sleeved between the guide rod 11 and the connecting plate 13. The two ends of the spring 15 are fixedly connected to the mounting block 10 and the connecting plate 13, respectively.

[0018] Specifically, when using this utility model, after the fishing time is reached, the controller starts the reel 9. The reel 9 reels the cable 6, pulling the bottom frame 5 upward from the bottom of the cage 3. The position of the bottom frame 5 can be adjusted according to the gathering requirements. When the bottom frame 5 leaves the water surface, the edge of the bottom frame 5 presses against the inclined surface of the trapezoidal limiting block 12, pulling the spring 15. When the bottom frame 5 leaves the trapezoidal limiting block 12, the trapezoidal limiting block 12 returns to its original position under the pull of the spring 15, which can support the bottom frame 5, making it easier to limit the height of the bottom frame 5 and making it easier to select. At the same time, it reduces the workload of the reel 9. After the fishing is completed, the L-shaped card plate 14 is pressed against the inside of the connecting plate 13, so that the connecting plate 13 pulls the trapezoidal limiting block 12 closer to the support column 7. After the bottom of the bottom frame 5 loses its limit, it can move downward and be put back into the water.

[0019] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
