Description

Technical Field

[0001] This utility model relates to the field of deep-sea aquaculture technology, specifically to a cage net for deep-sea aquaculture. Background Technology

[0002] Marine aquaculture is a production activity that utilizes coastal marine aquatic economic plants and animals; it includes various methods such as shallow-sea aquaculture, tidal flat aquaculture, and deep-sea aquaculture. The main species cultivated in marine aquaculture include fish, shrimp, crabs, shellfish, algae, and other marine delicacies.

[0003] Taking deep-sea aquaculture as an example, common deep-sea aquaculture cages are mainly made of high-density polyethylene or high-strength steel, which have advantages such as reasonable and stable structure, strong resistance to wind and waves, reduced labor costs, and convenient aquaculture. However, in actual use, when using deep-sea aquaculture cages for intensive aquaculture, poor management can easily have a negative impact on the surrounding marine environment. The main reason is that the excrement and feed residues discharged by aquatic products during the aquaculture process are generally directly discharged into the seawater. In order to increase output, some farmers will carry out high-density aquaculture beyond the limit. The insufficient self-cleaning capacity of the ocean can easily cause water pollution, which not only has a negative impact on the environment but is also not conducive to long-term deep-sea aquaculture.

[0004] Therefore, a deep-sea aquaculture cage net is invented to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] Therefore, the purpose of this utility model is to provide a deep-sea aquaculture cage net to solve the problem mentioned in the background art that the feces and feed residues discharged during the aquaculture process of existing deep-sea aquaculture cage nets are generally directly discharged into the seawater, which has a negative impact on the environment and is not conducive to long-term deep-sea aquaculture.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a deep-sea marine aquaculture cage net cover, comprising a main cage, a sludge collection cage fixedly connected to the bottom of the main cage, a shaft vertically arranged at the center of the main cage and the sludge collection cage, the shaft having a hollow internal structure, a sludge suction pipe horizontally fixedly connected to the bottom of the shaft, the sludge suction pipe being horizontally close to the bottom of the sludge collection cage, a plurality of suction nozzles distributed along the length of the bottom of the sludge suction pipe, a rotating component capable of driving the shaft to rotate axially and a suction connector component connected to the top of the shaft being provided at the top of the main cage, the suction connector component being connected to a sewage pump through an external pipeline.

[0008] As a preferred embodiment of the deep-sea aquaculture cage net cover described in this utility model, the mesh size of the main net cage is larger than that of the sludge collection net cage, and the junction of the main net cage and the sludge collection net cage is the main net cage body.

[0009] As a preferred embodiment of the deep-sea aquaculture cage net cover described in this utility model, a first support frame is fixed on the inner side of the top of the main net cage, and the upper end of the shaft is rotatably mounted on the first support frame through a bearing;

[0010] The rotating assembly includes a driven gear fixed to the outer periphery of the upper end of the shaft, a rotating shaft rotatably mounted on the first support frame, a main gear fixed to the outer periphery of the rotating shaft and meshing with the driven gear, and a speed reducer mounted on the upper part of the first support frame and whose output end is coaxially connected to the rotating shaft.

[0011] As a preferred embodiment of the aquaculture cage net cover for deep-sea marine aquaculture described in this utility model, the suction connector assembly includes a suction pipe coaxially disposed on the top of the rotating shaft, and a sealed bearing located at the connection between the suction pipe and the rotating shaft.

[0012] As a preferred embodiment of the aquaculture cage net cover for deep-sea marine aquaculture described in this utility model, a second support frame is fixed to the top of the inner side of the sludge collection net cage, and the second support frame has a bushing that is vertically and movably connected to the shaft at the center.

[0013] As a preferred embodiment of the aquaculture cage net cover for deep-sea aquaculture described in this utility model, the top of the first support frame is also provided with a fixed box cover covering the outside of the rotating component and the suction connector component.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This deep-sea aquaculture cage net, by dividing the circular structure of the cage net into a main cage and a sludge collection cage from top to bottom, achieves the effect of purifying aquaculture and preventing cross-infection. During use, the feces and other impurities discharged by the aquatic products in the main cage will fall directly into the sludge collection cage. The small mesh of the sludge collection cage can prevent feces and impurities from sinking and drifting into the sea. When cleaning is required, the rotating component will drive the shaft and the sludge suction pipe to rotate at a uniform speed, and the sludge pump will suck up the shaft and the sludge suction pipe through the suction connector component. The rotating sludge suction pipe can use the suction nozzle to perform a 360° covering suction and discharge of feces and impurities deposited at the bottom of the sludge collection cage. After completion, the operation stops. In summary, this deep-sea aquaculture cage net can effectively prevent and reduce the drawbacks of directly discharging feces and impurities into the sea during the aquaculture process, maintain the self-cleaning ability of the ocean, and greatly reduce the negative impact on the surrounding marine environment, which is conducive to scientific and long-term aquaculture.

Detailed Implementation

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Figures 1-3 The diagram shown is a complete structural schematic of a deep-sea aquaculture cage net according to this utility model. Please refer to [link / reference]. Figures 1-3 This embodiment of a deep-sea aquaculture cage includes a main cage 100, a sludge collection cage 200 fixedly connected to the bottom of the main cage 100, a shaft 300 vertically arranged at the center of the main cage 100 and the sludge collection cage 200, and the shaft 300 has a hollow internal structure. A sludge suction pipe 310 is horizontally fixedly connected to the bottom of the shaft 300 and is horizontally close to the bottom of the sludge collection cage 200. Several suction nozzles 3101 are distributed along the length of the bottom of the sludge suction pipe 310. The top of the main cage 100 is provided with a rotating component 400 that can drive the shaft 300 to rotate axially and a suction connector component 500 connected to the top of the shaft 300. The suction connector component 500 is connected to a sewage pump through an external pipeline.

[0023] The mesh size of the main net cage 100 is larger than that of the collection net cage 200, and the junction of the main net cage 100 and the collection net cage 200 is the main net cage 100. It can be understood that the main net cage 100 is used for aquaculture of marine products, such as deep-sea fish, while the collection net cage 200 is used to collect feces and other impurities discharged by the marine products. This prevents fish in the main net cage 100 from swimming into the collection net cage 200, thus isolating and preventing cross-infection. Furthermore, the smaller mesh size of the collection net cage 200 prevents feces and impurities from sinking and drifting into the sea, facilitating subsequent cleaning. A first support frame 110 is fixed to the inner side of the top of the main mesh cage 100, and the upper end of the shaft 300 is rotatably mounted on the first support frame 110 via a bearing. The rotating assembly 400 includes a driven gear 410 fixed to the outer periphery of the upper end of the shaft 300, a rotating shaft 420 rotatably mounted on the first support frame 110, a main gear 430 fixed to the outer periphery of the rotating shaft 420 and meshing with the driven gear 410, and a reducer 440 mounted on the upper part of the first support frame 110 and whose output end is coaxially connected to the rotating shaft 420. The suction coupling assembly 500 includes a suction pipe 520 coaxially disposed on the top of the rotating shaft 420, and a sealed bearing 510 located at the connection between the suction pipe 520 and the rotating shaft 420. It is understood that the outer end of the suction pipe 520 is connected to the sewage pump via an external pipeline (not shown in the figure), and the sewage pump does not obstruct the normal rotation of the rotating component 400 driving the rotating shaft 420 while suctioning. Furthermore, it should be noted that the cage mesh cover in this embodiment preferably adopts a circular structure. Specifically, in this embodiment, the circular cage mesh cover is divided into a main cage 100 and a sewage collection cage 200 from top to bottom, achieving the effect of purifying aquaculture and preventing cross-infection. During use, the feces and other impurities discharged by the aquatic products in the main cage 100 will fall directly into the sewage collection cage 200, and the small mesh of the sewage collection cage 200 can prevent the leakage of feces and impurities. When the fish sinks and drifts to the sea and needs cleaning, the rotating component 400 drives the shaft 300 and the sludge suction pipe 310 to rotate at a constant speed. The sludge pump uses the suction connector component 500 to suction the shaft 300 and the sludge suction pipe 310. The rotating sludge suction pipe 310 can use the suction nozzle 3101 to perform 360° covering suction and discharge of feces and dirt deposited at the bottom of the sludge collection cage 200. After completion, the operation stops. In summary, this deep-sea aquaculture cage can effectively prevent and reduce the drawbacks of directly discharging feces and dirt into the sea during the aquaculture process. It maintains the self-cleaning ability of the ocean and greatly reduces the negative impact on the surrounding marine environment, which is conducive to scientific and long-term aquaculture.

[0024] It should be noted that the sewage pump can pump the manure and waste in the breeding cage mesh to the sewage treatment area of ​​the breeding farm through the external pipeline and the suction connector 500. The sewage will be filtered and purified by professional sewage purification equipment and measures.

[0025] Preferably, a second support frame 210 is fixed to the top of the inner side of the sludge collection cage 200. The second support frame 210 has a bushing 220 that is vertically and movably connected to the shaft 300 at its center. It can be understood that since the cage mesh has a certain depth and the shaft 300 has a long downward stroke, the second support frame 210 and the bushing 220 can provide stable support for the lower part of the shaft 300, making it more stable when rotating.

[0026] Preferably, the top of the first support frame 110 is further provided with a fixed cover 600 covering the outside of the rotating component 400 and the suction connector component 500. It can be understood that the fixed cover 600 is used to position and install the rotating component 400 and the suction connector component 500, and at the same time serves as external protection.

[0027] In summary, this embodiment of a deep-sea aquaculture cage net, by dividing the circular cage net into a main cage 100 and a sludge collection cage 200 from top to bottom, achieves the effect of purifying aquaculture and preventing cross-infection. During use, feces and other impurities discharged by the aquatic products cultured in the main cage 100 will fall directly into the sludge collection cage 200. The small mesh size of the sludge collection cage 200 prevents feces and impurities from leaking, sinking, or drifting into the sea. When cleaning is required, the rotating component 400 will drive the shaft 300 and the sludge suction pipe 310. The pump rotates at a constant speed and draws suction from the shaft 300 and the suction pipe 310 through the suction coupling assembly 500. The rotating suction pipe 310 can use the suction nozzle 3101 to perform 360° coverage suction and discharge of feces and waste deposited at the bottom of the collection cage 200. After completion, the operation stops. In summary, this deep-sea aquaculture cage can effectively prevent and reduce the drawbacks of direct discharge of feces and waste into the sea during the aquaculture process. It maintains the self-cleaning ability of the ocean and also greatly reduces the negative impact on the surrounding marine environment.
