Technical Field

[0001] The utility model relates to the field of aquatic product breeding, in particular to a multifunctional breeding net cage for aquatic product breeding. Background Art

[0002] Aquaculture refers to the activity of cultivating, breeding and producing aquatic products by utilizing aquatic environment through artificial control and breeding methods. This activity can include marine organisms such as fish, crustaceans and shellfish, as well as freshwater organisms such as freshwater fish and turtles. Cages are required for aquaculture. Cages can be moved according to changes in the aquatic environment and adjustments to aquaculture needs, which enables farmers to manage the aquaculture process more flexibly. Cages can be used in a variety of aquatic environments, including open seas, nearshore areas, inland lakes, etc., and also facilitate farmers to carry out daily feeding, health monitoring and harvesting.

[0003] In the prior art, due to the concentrated discharge of fish metabolites and the residue of excess feed in the cage farming environment, the water body is very susceptible to eutrophication. Fish feces and incompletely utilized feed particles settle and accumulate around the cage, accelerating the increase in nutrient concentration in the local water area. The deterioration of water quality not only reduces the transparency of the water body and affects photosynthesis, but may also cause hypoxia events, posing a fatal threat to farmed fish. Therefore, the present application provides a multifunctional aquaculture cage for aquatic product farming to meet the demand. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a multifunctional aquaculture cage for aquatic product breeding to solve the problem that in existing cage breeding, fish feces and unconsumed feed will be deposited around the cage, causing water quality deterioration, and limited water exchange may cause harmful substances to accumulate, affecting fish health.

[0021] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the protection scope of the present invention.

[0022] The following is an explanation of the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0023] Reference Figure 1-Figure 4 A multifunctional breeding cage for aquatic product breeding includes a cage body 1, the cage body 1 includes: an upper accommodating space 103 and a lower accommodating space 104; a planting tray 9 installed on the cage body 1, the planting tray 9 is located in the lower accommodating space 104; and a plurality of aquatic plants 8 are arranged on the planting tray 9.

[0024] The cage body 1 provides an overall framework and support to ensure the stability and safety of the aquaculture system. By distinguishing the upper accommodating space 103 and the lower accommodating space 104, different ecological environments are created, which is conducive to the coexistence and mutual benefit of different biological species.

[0025] The planting tray 9 provides a growth medium for the aquatic plants 8 and is also a key component for filtering and purifying water. The aquatic plants 8 are used to absorb nutrients in the water, such as ammonia nitrogen and phosphate, reduce eutrophication of the water body, keep the water clean, provide additional biodiversity for the ecosystem in the cage body 1, promote ecological balance, produce oxygen through photosynthesis, replenish dissolved oxygen in the water body, and are beneficial to the survival of fish. Some aquatic plants 8 can be used as natural feed for fish, reducing the use of artificial feed and reducing costs.

[0026] The net box body 1 further comprises: a plurality of transverse support members 101 ; and a plurality of longitudinal support members 102 detachably mounted on the plurality of transverse support members 101 via connectors 105 .

[0027] The transverse support 101 is used to enhance the transverse rigidity of the cage and prevent the cage from deforming in the horizontal direction. The transverse support 101 is the main load-bearing part of the cage structure, supporting the weight of the water and the load of fish in the cage, as well as any additional equipment or structures, such as planting trays 9 and aquatic plants 8.

[0028] The longitudinal supports 102 are arranged in the length direction of the cage to increase the longitudinal strength of the cage and ensure that the cage can remain stable under the impact of water flow. The longitudinal supports 102 are connected to the transverse supports 101 through connectors 105 to form a grid structure to enhance the structural integrity of the entire cage.

[0029] The connecting member 105 enables the lateral supporting member 101 and the longitudinal supporting member 102 to be flexibly assembled and disassembled, thus facilitating the transportation, installation and maintenance of the cage.

[0030] Structural reinforcement: The connector 105 not only provides a connection function, but also enhances the overall structural strength of the cage through its design and material, thereby ensuring the durability of the cage in harsh environments.

[0031] The automatic feeding part 2 comprises: a mounting part 201; a food storage part 202, which is detachably mounted on the mounting part 201; and a plurality of automatic discharging pipes 203, which are evenly mounted on the food storage part 202, wherein the automatic discharging pipes 203 are provided with control valves.

[0032] The mounting member 201 is responsible for fixing the entire automatic feeding system at a suitable position of the net cage, and at the same time provides stable support for the food storage member 202 and the automatic discharging pipe 203 .

[0033] The food storage 202 is used to store a large amount of feed, usually in the form of dry granules or powder, for the automatic feeding system to distribute on demand. The detachable feature makes the food storage 202 convenient for adding, replacing and cleaning feed, and also convenient for maintenance and inspection.

[0034] The automatic discharge pipe 203 is used to transport the feed from the food storage part 202 to the designated area in the cage. The flow rate of the feed is adjusted by the built-in control valve to ensure that the amount of each feeding is accurately controllable. The setting of multiple automatic discharge pipes 203 ensures that the feed can be evenly distributed in different areas of the cage to avoid feed accumulation and waste, while promoting balanced feeding of fish. The control valve can also prevent too much feed from being released at one time, avoiding feed floating or sinking in the water, causing waste and water pollution.

[0035] A plurality of tension ropes 7 are installed on the transverse support member 101 ; a plurality of weight blocks 6 are installed on the plurality of tension ropes 7 respectively.

[0036] The tension rope 7 and the weight block 6 are connected to the transverse support 101 to provide the necessary tension for the cage, helping to maintain the shape and integrity of the cage structure, especially in severe weather conditions such as strong winds or big waves. The tension rope 7 and the weight block 6 are also used to anchor the cage to ensure its precise position in the water body and avoid drifting due to water currents or wind.

[0037] A plurality of anchor ropes 4 are evenly installed on the transverse support member 101 ; a plurality of anchor stones 5 are respectively installed on the plurality of anchor ropes 4 .

[0038] The anchor rope 4 is used to connect the lateral support 101 with the anchor stone 5 on the bottom of the water to resist the influence of water flow, wind, waves and other external forces. By using multiple anchor ropes 4, the load generated by external forces can be more evenly distributed, reducing the risk of single point failure, thereby improving the reliability and safety of the entire system. The length and tension of the anchor rope 4 can be adjusted to control the depth and direction of the cage body 1, which is very important for applications that require precise positioning.

[0039] The anchor stone 5 grabs the soil or rock on the seabed by its weight and design shape, such as an anchor with a claw, to provide sufficient grip to fix the anchor rope 4. The use of multiple anchor stones 5 increases the stability of the entire system, and can keep the position of the structure unchanged even in a harsh marine environment. Multiple anchor stones 5 mean that even if one of them fails, the other anchor stones 5 can still continue to function to ensure the safety of the structure.

[0040] The transverse support member 101 and the longitudinal support member 102 are made of high-density polyethylene material, and a partition net is arranged on the transverse support member 101 and the longitudinal support member 102 .

[0041] The high-density polyethylene material has excellent corrosion resistance, can resist salt erosion in seawater, and extend the service life of the support. The high-density polyethylene material usually has a certain buoyancy, which helps the cage body 1 to remain stable in the water. At the same time, its lightweight characteristics reduce the burden on the cage body 1 structure. This material has good resistance to ultraviolet rays and extreme temperatures and is suitable for long-term exposure to outdoor environments. Although it is lightweight, the high-density polyethylene still maintains good mechanical strength and toughness, and can withstand water pressure and external force impact in the cage.

[0042] The net cage body 1 further comprises a floating member 3 installed on the transverse supporting member 101 .

[0043] The main function of the floating member 3 in the cage culture system is to provide buoyancy to ensure that the cage can float stably on the water surface. The floating member 3 is made of lightweight and waterproof material, such as foam plastic or hollow polyethylene products, which can provide sufficient buoyancy to support the entire cage structure, including the weight of the water in the cage, the weight of the fish and the weight of other additional equipment. The floating member 3 can also serve as a buffer to reduce the impact force when the cage collides with other objects and protect the cage structure from damage.

[0044] During use, the cage body 1 is stably installed in the water by means of the floating member 3, anchor rope 4, anchor stone 5, weight block 6 and tension rope 7, while aquatic plants 8 are planted on the planting tray 9, shellfish aquatic products are cultured in the upper accommodating space 103, and fish aquatic products are cultured in the lower accommodating space 104.

[0045] Thus, although the present invention has been described herein with reference to specific embodiments thereof, freedom of modification, various changes and substitutions are also within the above disclosure, and it should be understood that in some cases, some features of the present invention will be adopted without corresponding use of other features without departing from the scope and spirit of the proposed utility model.
