Description

Technical Field

[0001] This utility model relates to the field of aquaculture cages, and in particular to an environmentally friendly aquaculture cage. Background Technology

[0002] With the rapid development of aquaculture, traditional pond farming methods not only consume a large amount of land resources but also easily lead to water pollution and ecological damage. Therefore, developing efficient, ecological, and environmentally friendly aquaculture technologies has become an urgent problem to be solved. As a result, integrated fixed fish cage technology has emerged. By setting up fixed cages of certain specifications and shapes in the water, fish can be raised using natural water resources, effectively solving many problems in traditional farming methods.

[0003] However, existing integrated fixed fish farming tanks fail to effectively collect and treat residual feed and fish waste, allowing it to be discharged indiscriminately, leading to the deterioration of water quality in the surrounding water bodies.

[0004] Therefore, there is an urgent need to design an efficient and environmentally friendly device for collecting uneaten feed and fish feces, in order to solve the problem of low efficiency in removing uneaten feed and fish feces in cage aquaculture, reduce water pollution, and improve the aquaculture environment. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an environmentally friendly aquaculture cage, solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an environmentally friendly aquaculture cage, including an annular bracket and a connecting plate, wherein the annular bracket and the connecting plate are connected by multiple connecting rods, the upper end of the annular bracket is fixed with a cage float by pipe clamps, and the upper port of the annular bracket is provided with guardrails on both the inner and outer sides of the cage float, and a cage netting is arranged between the annular bracket and the connecting plate;

[0007] A collector is fixed to the bottom of the connecting plate, and a manure collection bucket is connected to the bottom of the collector. A first counterweight is fixed to the bottom of the manure collection bucket by a connecting rope.

[0008] The bottom of the manure collection bucket is connected to a sewage pipe extending to the water surface. The sewage pipe is equipped with a negative pressure suction mechanism, and the inner side of the collector is equipped with a vortex flushing system for rinsing its inner wall.

[0009] As a further technical solution of this utility model, the interior of the manure collection bucket is connected to the interior of the collector, and a filter screen is provided at the top of the manure collection bucket. When the first counterweight sinks and pulls the manure collection bucket, the collector is in a conical state at the lower end of the connecting plate.

[0010] As a further technical solution of this utility model, the net cage is fixed to the connecting rod between the annular bracket and the connecting plate by welding or binding. The connecting plate is also annular in structure. The inner side of the net cage forms a breeding area between the annular bracket and the connecting plate.

[0011] The bottom outer side of the connecting plate has multiple second counterweights arranged in a circular array, and the second counterweights are connected to the connecting plate by connecting ropes.

[0012] As a further technical solution of this utility model, the negative pressure extraction mechanism includes a sewage pipe installed at the other end of the sewage main pipe, and an air extraction pipe connected to the other end of the sewage main pipe near the sewage pipe. A one-way valve and a shut-off valve are installed on the air extraction pipe, and a negative pressure exhaust fan is connected to the other end of the air extraction pipe.

[0013] The sewage pipe is equipped with a valve, and one end of the sewage pipe is connected to a manure storage bag. The manure storage bag has a double-layer conical structure, with a high-strength support mesh on the outer layer and a precision filter cloth on the inner layer. A bag sleeve is provided at the top of the manure storage bag. The manure storage bag is connected to the sewage pipe through the bag sleeve and is fixed with clamps.

[0014] As a further technical solution of this utility model, the vortex flushing system includes a water supply ring pipe installed on the inner wall of the connecting plate and a plurality of flushing pipes evenly distributed on the inner side of the water supply ring pipe. The water supply ring pipe is also connected to a flushing main pipe extending to the top of the annular bracket. The other end of the flushing main pipe is connected to a high-pressure water pump. The high-pressure water pump is located on the annular bracket, and the output end of the high-pressure water pump is connected to the flushing main pipe. The pumping end of the high-pressure water pump extends into the water through a pipe.

[0015] As a further technical solution of this utility model, multiple flushing pipes are inclinedly distributed on the inner wall of the collector, and each flushing pipe has multiple outlet pipes branching out. The water outlet direction of each flushing pipe is either counterclockwise or clockwise, and the outlet pipes are connected to the water supply ring pipe through the flushing pipes.

[0016] As a further technical solution of this utility model, the inner diameter of the end of the water outlet pipe near the flushing pipe is large, and the inner diameter of the end away from the flushing pipe is small.

[0017] This utility model provides an environmentally friendly aquaculture cage, which has the following advantages compared with the prior art:

[0018] 1. This design introduces an environmentally friendly aquaculture cage. A cone-shaped collector is added to the cage to allow for the self-sedimentation and collection of feed residue and fish feces, facilitating unified treatment. Furthermore, the combination of a negative pressure suction mechanism and a sewage pipe enables negative pressure adsorption treatment of feed residue and fish feces in the collection bucket, further improving the collection efficiency of fish feces within the aquaculture cage. This solves the problem of traditional aquaculture cages where fish feces and feed residue are difficult to handle, leading to their impact on water quality and the aquaculture environment inside the cage.

[0019] 2. This design introduces an environmentally friendly aquaculture cage with an added vortex flushing system inside the collector. This system facilitates long-term maintenance by flushing the inner wall of the collector with water, creating clockwise or counterclockwise vortices within the cage. This process concentrates fish feces and feed residue in the collection bucket at the bottom of the collector and also flushes away fish feces and feed residue adhering to the collector and the inner wall of the cage, improving the cleanliness of the cage and indirectly improving the water quality.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 This utility model provides an environmentally friendly aquaculture cage technology solution: the environmentally friendly aquaculture cage includes an annular bracket 1 and a connecting plate 5. The annular bracket 1 and the connecting plate 5 are connected by multiple connecting rods. The upper end of the annular bracket 1 is fixed with a cage float 2 by pipe clamps. The cage float 2 can be a ring-shaped buoyancy tube with a diameter of 400mm and a wall thickness of 19.1mm. The upper end of the annular bracket 1 is equipped with guardrails 3 on both the inner and outer sides of the cage float 2. The guardrails 3 are 900mm high, facilitating feeding and aquaculture management operations. The annular bracket 1 and the connecting plate 5... A net cage 4 is surrounded by a net cage. The net cage 4 is fixed to the connecting rod between the annular bracket 1 and the connecting plate 5 by welding or binding. The connecting plate 5 is also annular. The inner side of the net cage 4 is located between the annular bracket 1 and the connecting plate 5 to form a breeding area. When the breeding net cage is placed in the water, it will float on the water surface due to the action of the net cage float 2 and the annular bracket 1, while the breeding area is located in the middle. The breeding net cage is located inside the guardrail 3, which is the entrance to the breeding area. From this entrance, the farmed fish in the breeding area can be caught or fed.

[0029] Multiple second counterweights 7 are arranged in a circular array on the bottom outer side of the connecting plate 5, and the second counterweights 7 are connected to the connecting plate 5 by connecting ropes. The connecting ropes are used to pull the multiple second counterweights 7, so that after the aquaculture cage is put into the water, the second counterweights 7 can be used to counterweight and fix the aquaculture cage in a fixed water area, making it less likely to drift.

[0030] A collector 6 is fixed to the bottom of the connecting plate 5. A manure collection bucket 61 is connected to the bottom of the collector 6. A first counterweight 62 is fixed to the bottom of the manure collection bucket 61 by a connecting rope. The interior of the manure collection bucket 61 is connected to the interior of the collector 6. A filter screen 63 is provided at the top of the manure collection bucket 61. When the first counterweight 62 sinks and pulls the manure collection bucket 61, the collector 6 forms a cone shape at the lower end of the connecting plate 5 (e.g., ...). Figure 1As shown), a cone-shaped upper layer is formed in the lower part of the net cage, while the lower layer is connected to the manure collection bucket 61. In addition, in actual use, vortex calculations can be performed according to the volume of the net cage to ensure that the vortex formed by the water flow impact can achieve flushing inside the net cage. Furthermore, a cone-shaped collector 6 is added to the bottom of the aquaculture net cage to facilitate the unified collection of fish feces generated in the aquaculture area. The feces produced by the farmed fish in the aquaculture area will sink into the collector 6. Utilizing its own cone-shaped slope design, the fish feces can automatically fall into the manure collection bucket 61 and be discharged through the sewage pipe. In addition, the flushing of the vortex flushing system can be used to better collect the fish feces.

[0031] The bottom of the manure collection bucket 61 is connected to a main sewage pipe 9 extending to the water surface. A negative pressure suction mechanism is installed on the main sewage pipe 9, which includes a sewage pipe 94 installed at the other end of the main sewage pipe 9 and an air extraction pipe 91 connected to the other end of the main sewage pipe 9 near the sewage pipe 94. A one-way valve 93 and a shut-off valve 92 are installed on the air extraction pipe 91, and a negative pressure exhaust fan is connected to the other end of the air extraction pipe 91. A valve is installed on the sewage pipe 94, and a manure storage bag 95 is connected to one end of the sewage pipe 94. The manure storage bag 95 has a double-layer conical structure, with an outer layer of high-strength support mesh 951 and an inner layer of precision filter cloth 952 (pore size 80-100μm). A water flow channel is provided in the middle. The conical design of the manure storage bag 95 allows gravity to concentrate sediment, preventing accumulation and blockage. A bag-covering pipe 95 is provided at the top of the manure storage bag 95. 3. The manure storage bag 95 is connected to the sewage pipe 94 via the bag sleeve 953 and fixed with clamps (i.e., stainless steel butterfly bolts). The clamps are quick-release clamps, which can be easily disassembled and assembled with one hand when connected to the sewage pipe 94. A negative pressure suction mechanism is added to utilize the operation of a negative pressure fan to create suction by forming a negative pressure in the sewage main pipe 9, which facilitates the suction of feed residue and fish feces inside the manure collection bucket 61 into the sewage main pipe 9, and finally discharges them from the sewage pipe 94 into the manure storage bag 95. The manure storage bag 95 is normally submerged in water. When feed residue and fish feces are sucked into the sewage main pipe 9 and finally discharged from the sewage pipe 94 into the manure storage bag 95, the water in it is discharged from the holes of the manure storage bag 95, and the remaining residue and fish feces remain in the manure storage bag 95. The aquaculture personnel regularly lift the manure storage bag 95 out of the water and clean the inside.

[0032] The inner side of the collector 6 is equipped with a vortex flushing system for rinsing its inner wall. The vortex flushing system includes a water supply ring pipe 81 installed on the inner wall of the connecting plate 5 and multiple flushing pipes 82 evenly distributed inside the water supply ring pipe 81. The water supply ring pipe 81 is also connected to a flushing main pipe 8 extending above the annular bracket 1. The other end of the flushing main pipe 8 is connected to a high-pressure water pump 84. The high-pressure water pump 84 is located on the annular bracket 1, and the output end of the high-pressure water pump 84 is connected to the flushing main pipe 8. The water pumping end of the high-pressure water pump 84 extends into the water through a pipe, and a filter screen is installed at the end of its water pumping pipe that extends into the water to prevent other organisms from being sucked in.

[0033] Multiple flushing pipes 82 are obliquely distributed on the inner wall of the collector 6. Each flushing pipe 82 branches into multiple water outlet pipes 83. The water outlet pipes 83 on each flushing pipe 82 have a counterclockwise or clockwise water outlet direction. The water outlet pipes 83 are connected to the water supply ring pipe 81 through the flushing pipes 82. The multiple flushing pipes 82 are arranged in an array and are set at an angle, which facilitates the high-pressure water pump to send water from the flushing main pipe 8 into the water supply ring pipe 81, and then distribute it to each flushing pipe 82. Finally, the water is sprayed out from the water outlet pipes 83 to flush the inner wall of the collector 6. Moreover, the oblique array distribution and the uniform flushing direction can make the flushed water flow form a clockwise or counterclockwise flushing vortex on the inner wall of the collector 6, thereby better flushing and collecting fish feces on the inner wall of the collector 6. This can improve the cleanliness of the inner wall of the collector 6 and improve the fish feces collection efficiency.

[0034] Furthermore, the inner diameter of the end of the outlet pipe 83 near the flushing pipe 82 is large, while the inner diameter of the end away from the flushing pipe 82 is small. As a result, the inlet of the outlet pipe 83 is large and then gradually narrows, forming a Venturi principle. When water enters the outlet pipe 83 and is sprayed out from the other end, it will generate water flow impact and form a vortex inside the net cage. The vortex generated inside the net cage can not only flush the inner wall of the collector 6, but also impact the net cage 4, thereby improving the cleanliness of the inside of the net cage.

[0035] The working principle of this utility model is as follows: When in use, the aquaculture cage is placed in water, and the second counterweight 7 can stabilize the aquaculture cage in a certain area. During the aquaculture process, due to the frequent feeding of feed and the aquaculture manure produced, it will settle and fall to the collector 6. At this time, the cone-shaped design of the collector 6 itself can make the manure fall into the manure collection bucket 61.

[0036] Then, open the one-way valve 93 and the shut-off valve 92, and start the negative pressure exhaust fan to create a negative pressure in the sewage main pipe 9 to generate suction, so that the feed residue and fish feces inside the manure collection bucket 61 can be sucked into the sewage main pipe 9 and finally discharged from the sewage pipe 94 into the manure storage bag 95, which facilitates the collection and treatment of fish feces and feed residue in the aquaculture net cage and improves the water quality inside the aquaculture net cage.

[0037] Secondly, during long-term use, the high-pressure water pump 84 can be started to send water from the flushing main pipe 8 into the water supply ring pipe 81, then distribute it to each flushing pipe 82, and finally spray it out from the outlet pipe 83. This facilitates the flushing of fish feces and food residues attached to the inner wall of the collector 6, ensuring that the fish feces and food residues fall into the feces collection bucket 61 better, which can improve the efficiency of fish feces collection and also ensure the cleanliness of the inner wall of the collector 6.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
