Abstract

This utility model relates to the field of fish manure removal technology, and discloses a biomimetic fish aquaculture pond, including: an aquaculture pond, with a drainage channel connected to the center of the bottom of the aquaculture pond, and a valve installed in the drainage channel. In this utility model, the drainage channel and the manure discharge pipe with valve are connected to the center of the bottom of the aquaculture pond. Multiple sets of equidistantly distributed manure discharge holes at the bottom of the manure discharge pipe facilitate the concentrated discharge of manure. Because a manure-gathering and cleaning mechanism is installed on the outside of the manure discharge pipe, in conjunction with a water guide pipe and a drive component, the manure-gathering and cleaning mechanism can be rotated, causing the water inside the aquaculture pond to rotate, creating a vortex near the drainage channel. This accelerates the gathering of fish manure at the bottom of the aquaculture pond at the bottom of the manure discharge pipe, speeding up the discharge of manure from the manure discharge holes. Furthermore, the cleaning brush at the bottom of the spiral frame rotates on the outside of the manure discharge holes, cleaning the fish manure blocking the outside of the manure discharge holes, preventing fish manure from clogging the manure discharge holes, effectively reducing manual cleaning costs and improving aquaculture efficiency.

Description

Technical Field

[0001] This utility model relates to the field of manure removal technology for aquaculture ponds, and in particular to a biomimetic aquaculture pond for fish. Background Technology

[0002] Currently, in the traditional aquaculture sector, the design and management of aquaculture ponds play a crucial role in improving aquaculture efficiency and ensuring aquaculture quality. Existing aquaculture ponds have many shortcomings in terms of manure removal and daily management. These problems not only increase aquaculture costs but also limit the improvement of aquaculture efficiency.

[0003] In the current aquaculture industry, the ponds with flat or simple sloping bottoms are commonly used. However, fish excrement is difficult to collect and discharge effectively. The excrement is widely distributed at the bottom of the pond, which can easily form a pollution layer, affecting water quality and increasing the risk of disease. At the same time, due to the lack of an effective discharge mechanism, farmers need to invest a lot of manpower in regular cleaning, which is not only labor-intensive but also often unsatisfactory, making it difficult to completely remove the residue at the bottom of the pond.

[0004] To address these issues, we propose a biomimetic fish farming pond that offers highly efficient waste removal. Summary of the Invention

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a biomimetic fish farming pond.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A biomimetic fish farming pond includes: a farming pond, a drainage channel connected to the middle of the bottom of the farming pond, a valve installed in the drainage channel, a manure discharge pipe connected to the top of the drainage channel, several manure discharge holes opened on the manure discharge pipe near the bottom of the inner cavity of the farming pond, a manure collection and cleaning mechanism rotatably installed on the top of the outer side of the manure discharge pipe, blades provided on the outer side of the manure collection and cleaning mechanism, a water guide pipe distributed on one side of the top of the farming pond, the water guide pipe is configured as a fluid transport channel to introduce external water into the system, the blades are configured as a power receiving structure, the kinetic energy of the water transported by the water guide pipe acts on the surface of the blades, causing the blades to rotate.

The cleaning brush corresponds to multiple sets of manure discharge holes. The blades are fixedly installed on the outside of the drive ring. The blades are curved, and the hydrodynamic pressure generated by the curved surface of the blades forms a vertically downward force, causing vortices to be generated in the aquaculture pond.

[0009] Preferably, a second bearing is rotatably mounted on the bottom outer side of the manure pipe, and the inner side of the drive ring is rotatably connected to the side wall of the manure pipe through a first bearing. Both the second bearing and the outer side of the first bearing are fixed with bolts, and the two sets of fixed components are respectively fixedly connected to both sides of the spiral frame.

[0010] Preferably, the aquaculture pond is rectangular in shape, and the four corners of the pond wall are all arc-shaped to facilitate the rotation of water inside the pond.

A shade net is fixedly connected between the two U-shaped frames. One of the U-shaped frames is fixedly installed on the side wall of the aquaculture pond. The unfolded length of the shade net is not less than half the width of the aquaculture pond, so as to provide shade for the aquaculture pond.

[0014] Preferably, the multiple sets of discharge holes are arranged in a ring at the bottom of the discharge pipe, which can discharge fish feces into the discharge pipe from multiple angles.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention features a drainage channel and a manure discharge pipe with a valve connected to the center of the bottom of the aquaculture pond. Multiple sets of equidistantly distributed manure discharge holes at the bottom of the pipe facilitate the concentrated discharge of manure. A manure-collecting and cleaning mechanism is installed on the outside of the pipe, which, in conjunction with a water guide pipe and a drive assembly, rotates, causing the water inside the aquaculture pond to swirl.

[0018] 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.

[0019] Example 1: Refer to Figure 1-4A biomimetic fish farming pond includes: a farming pond 1, with a drainage channel 11 connected to the bottom center of the farming pond 1, a valve installed inside the drainage channel 11, and a manure discharge pipe 12 connected to the top of the drainage channel 11. The manure discharge pipe 12 has several manure discharge holes 13 near the bottom of the inner cavity of the farming pond 1. A manure collection and cleaning mechanism is rotatably installed on the top of the outer side of the manure discharge pipe 12, with blades 21 on the outer side of the manure collection and cleaning mechanism. Water guide pipes 15 are distributed on one side of the top of the farming pond 1, configured as fluid transport channels to introduce external water into the system. The blades 21 are configured as power receiving structures; the kinetic energy of the water transported by the water guide pipes 15 acts on the surface of the blades 21, causing the blades to rotate. The structure includes a drive ring 2 and a cleaning brush 24 installed at one end of the side wall of the drive ring 2 via a connecting assembly. The cleaning brush 24 corresponds to multiple sets of manure discharge holes 13. The blades are fixedly installed on the outside of the drive ring 2. The blades 21 are curved, and the hydrodynamic pressure generated by the curved surface of the blades 21 forms a vertically downward force, causing vortices to be generated in the aquaculture pond 1. The connecting assembly includes a spiral frame 22 installed at one end of the side wall of the drive ring 2. An installation rod 23 is fixedly connected to the bottom of the spiral frame 22. The side wall of the installation rod 23 is detachably installed to the cleaning brush 24 via bolts. The spiral frame 22 is sleeved on the outer wall of the manure discharge pipe 12. Multiple sets of manure discharge holes 13 are distributed in a ring at the bottom of the manure discharge pipe 12, which can discharge fish feces into the manure discharge pipe 12 at multiple angles.

[0020] A drainage channel 11 and a manure discharge pipe 12 with a valve are connected and installed at the bottom center of the aquaculture pond 1. The manure discharge pipe 12 has multiple sets of manure discharge holes 13 distributed in a ring at equal intervals at the bottom, which facilitates the collection and discharge of manure. Since a manure collection and cleaning mechanism is installed on the outside of the manure discharge pipe 12, together with the water guide pipe 15 and the drive component, the manure collection and cleaning mechanism can be driven to rotate, which drives the water inside the aquaculture pond 1 to rotate, so that a vortex is formed near the drainage channel 11. This accelerates the collection of fish manure at the bottom of the aquaculture pond 1 to the bottom of the manure discharge pipe 12, and accelerates the discharge of manure from the manure discharge holes 13. In addition, the cleaning brush 24 at the bottom of the spiral frame 22 rotates on the outside of the manure discharge holes 13, which can clean the fish manure blocking the outside of the manure discharge holes 13, prevent the fish manure from clogging the manure discharge holes 13, effectively reduce the cost of manual cleaning, and improve the aquaculture efficiency.

[0021] Furthermore, support shafts 3 are fixedly installed on the top of both sides of the aquaculture pond 1. Two sets of damping bearings 31 are rotatably installed on the outer side of the two sets of support shafts 3. A U-shaped frame 32 is fixedly installed between the damping bearing on one side of the aquaculture pond and the corresponding damping bearing 31 on the other side of the aquaculture pond. A shade net 33 is fixedly connected between the two U-shaped frames 32. One of the U-shaped frames 32 is fixedly installed on the side wall of the aquaculture pond 1. The length of the shade net 33 when unfolded is not less than half the width of the aquaculture pond 1, so as to provide shade for the aquaculture pond 1.

[0022] The operator can flexibly adjust the degree of unfolding of the shade net 33 according to the light intensity and weather conditions. When the sunlight intensity is high, the two sets of U-shaped frames 32 distributed on the outside can be rotated to fully unfold the shade net 33, covering half of the breeding pond 1 and providing a suitable environment for the fish. Conversely, in suitable weather, the two sets of U-shaped frames 32 can be overlapped to facilitate the storage of the shade net 33.

[0023] Furthermore, a second bearing is rotatably installed on the bottom outer side of the manure pipe 12, and the inner side of the drive ring 2 is rotatably connected to the side wall of the manure pipe 12 through the first bearing. Both the second bearing and the outer side of the first bearing are fitted with fixing parts 25 by bolts, and the two sets of fixing parts 25 are fixedly connected to both sides of the spiral frame 22 respectively.

[0024] When the spiral frame 22 rotates with the drive ring 2, it is not easy for it to shake or shift during rotation because the spiral frame 22 is mounted on the first bearing and the second bearing by two sets of fixing parts 25 on both sides, thus ensuring the stable operation of the cleaning work.

[0025] Furthermore, the aquaculture pond 1 is rectangular in shape, and the four corners of the pond wall are all arc-shaped to facilitate the rotation of water inside the aquaculture pond 1.

[0026] This not only reduces the possibility of fish being injured by colliding with the corners of the pond while swimming, providing a safer growth environment for the fish, but also reduces the impact of water flow on the curved inner wall, making it easier for the water to rotate within the breeding pond 1 and form eddies.

[0027] Furthermore, a cover plate is installed on the top of the sewage pipe 12, and multiple sets of equidistant through holes are opened on the cover plate to facilitate ventilation of the sewage pipe 12.

[0028] The cover plate prevents large debris from entering the sewage pipe 12 and causing blockage, while the through hole ensures that water and feces can smoothly enter the sewage pipe 12, maintaining the normal operation of the sewage system.

[0029] Furthermore, it also includes a drive component, which includes a pump 14. The pump 14 is fixedly installed at the bottom of the side wall of the aquaculture pond 1. The water inlet of the pump 14 is connected to the water source through a conduit, and the water outlet of the pump 14 is connected to the water guide pipe 15 to increase the power of the water guide pipe 15 to transport water.

[0030] The water flow into the water pipe 15 can be flexibly controlled by the pump 14 to provide power for the manure collection and cleaning mechanism. At the same time, the water flow can be adjusted as needed to meet the needs of different breeding stages.

[0031] Example 2: Refer to Figure 5-6 The breeding pond 1 is square in shape, with the four corners of the pond wall being arc-shaped, and the bottom and sides of the breeding pond 1 being smooth.

[0032] Because the breeding pond 1 is square, it can effectively reduce the turbulence of water flow at the corners of the pond wall and reduce energy loss. The water guide pipe 15 is distributed on the side wall of the breeding pond 1 and discharges clean water at an angle, forming a directional water flow force that can drive the clean water inside the breeding pond 1 to rotate, thereby driving the manure collection and cleaning mechanism on the outside of the manure discharge pipe 12 to rotate. This makes the driving effect of the water flow on the manure collection and cleaning mechanism more uniform and efficient, and the manure discharge effect is significantly improved, resulting in better manure discharge.

[0033] During use, fish excrement accumulates at the bottom of the aquaculture pond 1 during the aquaculture process. When it is necessary to perform a defecation operation, the valve in the drainage channel 11 is opened, and the pump 14 is started to draw water from the water source and deliver it to the top side of the aquaculture pond 1 through the water guide pipe 15. The water guide pipe 15 corresponds to the manure collection and cleaning mechanism. The water flow impacts the manure collection and cleaning mechanism, pushing it to rotate on the outside of the manure discharge pipe 12. When the manure collection and cleaning mechanism rotates, it drives the water inside the aquaculture pond 1 to rotate, forming a vortex near the drainage channel 11. The vortex has a strong adsorption force, which can accelerate the accumulation of fish excrement at the bottom of the aquaculture pond 1 at the bottom of the manure discharge pipe 12. Subsequently, under the action of gravity and the driving force of the water flow, the fish excrement enters the manure discharge pipe 12 through the manure discharge hole 13 at the bottom of the manure discharge pipe 12, and is finally discharged from the aquaculture pond 1 through the drainage channel 11, realizing the centralized discharge of excrement. When the water flow impacts the blade 21, the blade 21 drives the drive ring 2 to rotate. During the rotation of the drive ring 2, the screw frame 22 rotates accordingly, driving the mounting rod 23 and the cleaning brush 24 to rotate outside the manure discharge hole 13. The cleaning brush 24 can clean the fish feces blocking the manure discharge hole 13, preventing fish feces from blocking the manure discharge hole 13, ensuring the smooth flow of the manure discharge system, effectively reducing manual cleaning costs, and improving aquaculture efficiency. The operator can flexibly adjust the degree of unfolding of the shade net 33 according to the light intensity and weather conditions. When the sunlight intensity is high, the two sets of U-shaped frames 32 distributed on the outside can be rotated to fully unfold the shade net 33, covering half of the breeding pond 1 and providing a suitable environment for the fish. Conversely, in suitable weather, the two sets of U-shaped frames 32 can be overlapped to facilitate the storage of the shade net 33 and save space.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
