Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment, and in particular to a multi-layer partitioned aquaculture cage. Background Technology

[0002] Multi-layer partitioned aquaculture cages are a type of modular, three-dimensional aquaculture equipment. They consist of multiple independent, layered aquaculture compartments stacked vertically with reinforced frames. Their core feature is the ability to achieve symbiotic aquaculture of different sizes of aquatic products (such as shrimp farming in the upper layer, fish fry breeding in the middle layer, and filter-feeding shellfish farming in the bottom layer) through physical separation. This increases the stocking density, reduces cross-infection of diseases, and is suitable for nearshore and deep-sea cage aquaculture scenarios.

[0003] Currently available aquaculture cages are complex to operate, inconvenient to install and disassemble, have insufficiently sturdy stacking of frames, low maintenance efficiency, and the netting used in aquaculture cages for a long time is prone to corrosion or damage, requiring regular maintenance and repair.

[0004] Therefore, those skilled in the art have provided a multi-layered, partitioned aquaculture cage to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a multi-layered, partitioned aquaculture cage with a detachable structure that allows for quick replacement and disassembly of the netting, improving maintenance efficiency, ensuring the stability and safety of the device, limiting the activity range of fish, and preventing the escape of aquatic organisms. It also features a fixing structure to secure the multiple layers of aquaculture cages together and uses partitions to separate different aquatic organisms, enabling symbiotic aquaculture, increasing stocking density, and each layer has an independent door for easy removal and placement of aquatic organisms.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-layer partitioned aquaculture cage includes a support base, the bottom of which is provided with a detachable structure, and the top of which is provided with two fixing structures.

[0008] The disassembly structure includes two compression grooves located inside the support base. A compression spring is fixedly connected inside the compression groove. A limit block is fixedly connected to one side of the compression spring. A locking rod is fixedly connected inside the limit block. A sliding groove is provided at the bottom of the support base. A mesh is provided inside the sliding groove. Both ends of the mesh are provided with locking slots, which engage with the locking rod.

[0009] The above technical solution, with its disassembly structure, enables rapid replacement of the netting, improving maintenance efficiency, ensuring the usability of the netting, preventing the escape of aquatic organisms, and allowing for segmented disassembly without the need for overall hoisting of the net cage, thus reducing work difficulty and extending the service life of the netting.

[0010] Furthermore, the fixing structure includes two movable slots located inside the support base. A fixing spring is fixedly connected inside the movable slot. A fixing ring is fixedly connected to one end of the fixing spring. A locking post is fixedly connected inside the fixing ring. A pull rod is fixedly connected to one end of the locking post. Four fixing slots are provided on the top of the support base. Fixing posts are provided inside the fixing slots. Fixing holes are provided in the middle of the fixing posts. The fixing holes are engaged with the locking posts. An aquaculture chamber is provided inside the support base.

[0011] By using the above technical solutions and setting up a fixed structure, multi-layer aquaculture cages can be quickly constructed, improving installation efficiency, reducing labor costs, and utilizing the multi-layer structure to cultivate a variety of aquatic organisms, thereby increasing the stocking density.

[0012] Furthermore, the top of the support base is provided with eight grooves, and a limiting plate is provided inside the grooves. A filter plate is fixedly connected to one side of the limiting plate.

[0013] The above technical solutions promote water flow, improve water flow efficiency, ensure the cleanliness of aquaculture water, and reduce blockages and pollutant discharge.

[0014] Furthermore, each of the two limiting plates is provided with four limiting grooves at its top, and a partition plate is engaged inside the limiting groove;

[0015] The above technical solution uses partitions to divide the aquaculture tank into sections, separating different aquatic organisms to achieve symbiotic aquaculture.

[0016] Furthermore, a switch door is provided in the middle of one of the limiting plates, a buckle is fixedly connected to the top of the switch door, the bottom of the switch door is rotatably connected to the limiting plate through a hinge, and a fixing seat is fixedly connected to one side of the limiting plate, the fixing seat is engaged with the buckle through a pin.

[0017] The above technical solution allows for the installation of a switch door without requiring overall disassembly, facilitating individual feeding and convenient removal and placement of corresponding aquatic organisms.

[0018] Furthermore, a handle is fixedly connected to one side of the mesh cover;

[0019] Using the above technical solution, the mesh can be unlocked by the disassembly structure, and then the handle can be pulled to remove the mesh.

[0020] Furthermore, the top of the support base is provided with a top plate, and the bottom of the top plate is fixedly connected with four fixed columns;

[0021] The above technical solution involves installing a top plate to protect the aquaculture chamber and prevent aquatic organisms from jumping out.

[0022] This utility model has the following beneficial effects:

[0023] 1. This utility model proposes a multi-layered, partitioned aquaculture net cage. By setting up a disassembly structure, the net is fixed using clamps and slots. Pulling the clamps releases the net from the slots, and pulling the handle removes the net. The operation is simple and easy to maintain. The disassembly of each section eliminates the need for hoisting the entire net cage, reducing the difficulty of the work, reducing labor costs, improving maintenance efficiency, and ensuring the integrity of the net. This limits the activity range of fish, prevents aquatic organisms from escaping, and improves the availability of the equipment and the service life of the net.

[0024] 2. The multi-layer partitioned aquaculture cage proposed in this utility model uses a fixed structure, with locking posts and fixing holes, to firmly fix the fixing posts and support base together, thereby quickly building a multi-layer aquaculture cage. The operation is simple and the installation efficiency is improved. By using limiting grooves and partition plates, the aquaculture compartments inside the aquaculture cage are divided into partitions, thereby building a multi-layer partitioned aquaculture cage, separating different aquatic organisms, realizing symbiotic aquaculture, and increasing the aquaculture density.

[0025] 3. The multi-layer partitioned aquaculture cage proposed in this utility model can remove and put in aquatic organisms in each layer of the aquaculture chamber separately by setting up opening and closing doors, without disassembling the overall structure. The modular design enables single-chamber operation without disassembling the cage, thus improving work efficiency. Attached Figure Description
