Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, specifically relating to an aquaculture cage. Background Technology

[0002] Aquaculture refers to the production activities of raising aquatic economic plants and animals in artificially controlled water bodies, such as ponds, lakes, reservoirs, river bends, coastal mudflats, and various indoor and outdoor water bodies. Net cages are set up in the water body to house the cultured organisms. This method makes full use of water space, especially in areas with vast water areas that are not suitable for large-scale reclamation, such as large lakes, reservoirs, and nearshore waters. The net cages can be adjusted according to the size and growth stage of the cultured organisms and facilitate centralized management and harvesting.

[0003] Most existing aquaculture cages rely on external electromechanical mechanisms for depth adjustment. Since these cages are submerged for extended periods, the lifespan of these mechanisms is inevitably short, resulting in high operating costs and hindering widespread adoption. Furthermore, to ensure stability, multiple cages are often connected together. However, since most cages are rectangular or circular, they require a significant area to install. This often involves direct splicing, resulting in small gaps between cages that impede the removal of waste and negatively impact the quality of aquaculture. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing aquaculture cages are submerged in water for extended periods, resulting in short lifespans and high operating costs for the electromechanical structures used to control cage depth. Furthermore, the small gaps between cages when they are connected negatively impact the quality of aquaculture.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is an aquaculture cage, which includes multiple cage bodies. The cage body is generally in the shape of a regular hexagon, and a cover is fastened to the top of the cage body. An extension edge extending out of the side of the cage body is provided on the top of the cage body. A filling groove is provided at the hexagonal corner of the cage body, and multiple buoyancy blocks are placed in the filling groove.

[0006] A connecting block is provided at the top of the filling groove, and a positioning rod is provided above the connecting block. The buckle is inserted and fixed to the positioning rod, and multiple cage bodies are connected by the connecting block. A lifting ring is connected above the connecting block by multiple positioning rods.

[0007] As a preferred embodiment of this utility model, the shape of the cover matches the shape of the extension edge, and the middle of the cover is provided with a grid that matches the internal shape of the cage body.

[0008] As a preferred technical solution of this utility model, the filling groove extends from the bottom of the cage body to the upper extension edge, and the filling groove is provided with an open structure at the hexagonal edge of the cage body.

[0009] As a preferred embodiment of this invention, the buoyancy block is matched with the shape of the filling groove.

[0010] As a preferred technical solution of this utility model, the connecting block is composed of three structures with the same shape as the filling groove, arranged in a ring at equal angles, and the positioning rods are all located above the filling groove. The thickness of the connecting block is the same as that of the extension edge.

[0011] As a preferred embodiment of this utility model, the two sides of the extension edge are positioned by being inserted into the connecting block via positioning bolts.

[0012] As a preferred technical solution of this utility model, the bottom of the positioning rod lifting ring is provided with a connecting seat for inserting into the two positioning rods, and one side of the connecting seat is fixed to the connecting seat by a fixing bolt.

[0013] The advantages of this utility model compared with the prior art are as follows:

[0014] This aquaculture cage features multiple filling grooves and buoyancy blocks along its outer edge. The number of buoyancy blocks can be adjusted to regulate the depth of the cage underwater. Furthermore, the extension edge at the top edge of the cage effectively increases the spacing between cages, and the hexagonal shape of the cage body reduces the area occupied after splicing.

[0024] Example 1:

[0025] As per the instruction manual Figure 1-3 As shown, an aquaculture cage includes multiple cage bodies 1. The cage body 1 is generally hexagonal in shape, and a cover 2 is fastened to the top of the cage body 1. An extension edge 3 extending from the side of the cage body 1 is provided at the top of the cage body 1. The shape of the cover 2 matches the extension edge 3, and the middle of the cover 2 matches the internal shape of the cage body 1. A filling groove 4 is provided at the hexagonal corner of the cage body 1. The filling groove 4 extends from the bottom of the cage body 1 to the upper extension edge 3, and the filling groove 4 has an open structure at the hexagonal edge of the cage body 1. Multiple buoyancy blocks 5 are placed in the filling groove 4, and the buoyancy blocks 5 match the internal shape of the filling groove 4.

[0026] In this utility model, a connecting block 6 is provided on the top of the filling groove 4, and a positioning rod 7 is provided above the connecting block 6. The cover 2 is inserted and fixed to the positioning rod 7.

[0027] As per the instruction manual Figure 4As shown, the multiple cage bodies 1 are connected by connecting blocks 6.

[0028] As per the instruction manual Figure 5 As shown, the connecting block 6 is composed of three structures with the same shape as the filling groove 4, arranged in a ring at equal angles. The positioning rods 7 are all located above the filling groove 4. The connecting block 6 has the same thickness as the extension edge 3. The two sides of the extension edge 3 are connected to the connecting block 6 by positioning bolts 10. The bottom of the lifting ring 8 of the positioning rod 7 is provided with a connecting seat 11 that is inserted into the two positioning rods 7. One side of the connecting seat 11 is connected to the connecting seat 11 by a fixing bolt 12.

[0029] In a specific implementation of this utility model, multiple buoyancy blocks 5 provide buoyancy to the net cage body 1, enabling it to float on the water surface. The height of the net cage body 1 in the water body can be adjusted by adjusting the number of buoyancy blocks 5. A lifting ring 8 is connected above the connecting block 6 by multiple positioning rods 7. The lifting ring 8 can be used for lifting, moving, or fixing the net cage in a specific water area. For example, the lifting ring 8 can be connected to a fixing device on the bottom of the water by ropes to limit the range of movement of the net cage.

[0030] The main body 1 of the net cage is in the shape of a regular hexagon. This shape can make more efficient use of space when splicing multiple net cages. Compared with other shapes such as squares, the regular hexagon can reduce gaps when splicing, allowing more net cages to be placed in a limited water area, thereby increasing the density of aquaculture. The distance between two net cage bodies 1 after splicing is increased by extending the edge 3. Multiple net cage bodies 1 are positioned by the positioning bolts 10 and connecting blocks 6 on both sides of the extension edge 3. The combination and fixation between net cages are achieved by the insertion of the positioning rods 7. At the same time, the cover 2 can better seal the net cage space, providing a relatively independent and safe aquaculture environment for aquaculture.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
