[0035] Please refer to Figure 1 - Figure 7 , this embodiment provides a new type of breeding pond, including:

[0036] Pool basin 1;

[0037] A sewage barrel 2, which is placed at the bottom of the pool 1; the sewage barrel 2 includes a sewage inlet 210, a cavity 220, and a sewage outlet 230 which are interconnected;

[0038] A first filter element 3, wherein the outer edge of the first filter element 3 is connected to the edge of the sewage inlet 210, and the first filter element 3 is provided with a first filter gap 310 for allowing shrimp feces and other types of dirt smaller than shrimp shells to pass through;

[0039] A second filter element 4, one end of which is slidably connected to the first filter element 3, and the second filter element 4 is provided with a second filter gap 410 for allowing shrimp shells to pass through; the second filter gap 410 is larger than the first filter gap 310;

[0040] A first sewage pipe 5, the first sewage pipe 5 is located at the lower side of the bottom of the basin 1; the first sewage pipe 5 is connected to the sewage outlet 230;

[0041] A power device 6, wherein the inlet end of the power device 6 is connected and communicated with the other end of the second filter element 4;

[0042] The power device 6 is used to generate pumping power to pump the shrimp shells and dead shrimps outside the second filter gap 410 into the second filter element 4 through the second filter gap 410, and then into the second sewage pipe 7 through the power device 6, and finally into the storage chamber 810 from the outlet of the second sewage pipe 7. This prevents the dead shrimps from staying at the bottom of the pond for a long time, and the live shrimps from eating the diseased dead shrimps and being infected with the virus.

[0043] The power device 6 can be any one of a water pump and an air pump.

[0044] A second sewage pipe 7, one end of which is connected to the outflow end of the power device 6;

[0045] The separation container 8 is provided with a storage cavity 810, and the side wall is provided with a third filtering gap 820 that does not allow shrimp shells to pass through; the other end of the second sewage pipe 7 extends into the storage cavity 810, and the outlet height of the second sewage pipe 7 is lower than the opening height of the separation container 8.

[0046] The separation container 8 is in the shape of a basket and is provided with a hook, which is hung on the edge of the pool basin 1, so that the breeding staff can directly take out the separation container 8 from the pool basin 1 when cleaning is needed.

[0047] Compared with the prior art, the present novel breeding pond can only open one connection port at the bottom of the basin 1 to connect with the sewage barrel 2, and eliminates the need to set other openings at the bottom of the basin 1 for the sewage pipe or other pipelines to pass through. Therefore, the processing difficulty of the basin 1 can be reduced, and the basin 1 has better sealing performance, which can further avoid water leakage defects in the basin 1.

[0048] Also, the power device 6 and the sewage tank 2 are set at the same place to avoid being set up in two areas of the breeding pond respectively. Then, during the working filtration process, the water flows and the power device 6 starts, and the noise emitted is at the same position, which can better avoid disturbing the life of the organisms in the breeding pond and enable the organisms to grow well.

[0049] In addition, the power device 6 is arranged adjacent to the second filter element 4, and the power device 6 is closer to the water inlet of the second filter gap 410 of the second filter element 4, so the power device 6 can better generate pumping suction, and more efficiently and effectively transport the shrimp shells from the second filter gap 410 to the storage chamber 810. Compared with the prior art in which the power device is arranged far away from the classifier, the pumping suction pumping water flow effect is not good, and the design scheme of the present application has significant progress.

[0050] In addition, compared with the complex structure of the classifier in the prior art, the sewage barrel 2 of the present application has a simpler structure, is more convenient to produce and manufacture, and is convenient to connect and install with other components.

[0051] Please refer to Figure 1 - Figure 4 , including an air supply pipe 9; an oxygen explosion pipe 10 is provided in the cavity 220 and is arranged adjacent to the first filter element 3; the air supply pipe 9 is arranged along the first sewage pipe 5, passes through the sewage barrel 2, and is connected to the air inlet end of the oxygen explosion pipe 10.

[0052] The oxygen explosion pipe 10 can be arranged in a spiral shape on the lower end surface of the first filter element 3. The oxygen explosion pipe 10 with this structure can provide better and more gas oxygen content; when there is no need to clean the waste and dirt in the breeding pond, the first sewage pipe 5, the power unit 6, and the second sewage pipe 7 are closed, and the oxygen explosion pipe 10 works to supply oxygen to the entire breeding pond.

[0053] Since the oxygen explosion pipe 10 is located in the cavity 220 and the sewage inlet 210 is surrounded by the first filter element 3, the gas flow provided by the oxygen explosion pipe 10 will impact the first filter gap 310, so that some first filter gaps 310 that may be blocked by waste and dirt can be unblocked under the impact of the air flow, thereby keeping the first filter gaps 310 from being blocked. This design layout is ingenious and reasonable.

[0054] The air supply pipe 9 is arranged along the first sewage pipe 5, passes through the sewage barrel 2, and is connected to the air inlet end of the oxygen explosion pipe 10. This design can avoid drilling holes in the pool 1 and reducing the sealing performance. At the same time, compared with the prior art, the air supply pipeline of the oxygen explosion pipe extends into the inner cavity of the flushing water pipe, and the pipeline is laid out from its support frame, which is time-consuming and laborious to install, and the gas is transported from top to bottom along the pipeline, requiring the oxygen supply pump to generate more power consumption.

[0055] The air supply pipe 9 of the present application can easily transport the air supply pipe 9 located below the bottom surface of the pool 1 into the cavity 220, and by taking advantage of the fact that the density of gas is smaller than that of liquid, the gas rises spontaneously, and the power consumption of the oxygen supply pump is small. It also prevents the air supply pipe 9 from being located above the pool 1 and being easily aged by exposure to the sun, and prevents the protective cover (not shown) that cooperates with the support frame 12 from being pulled open or closed with the support frame 12.

[0056] Please refer to Figure 1 - Figure 4 , including an air supply pipe 9; the power device 6 includes an inner tube body 610 and an outer tube body 620 sleeved on the inner tube body 610; a accommodating area 630 is provided between the outer tube body 620 and the inner tube body 610; a plurality of air-permeable through holes 611 connected to the accommodating area 630 are provided on the tube wall of the inner tube body 610; an airflow connecting pipe 621 is connected to the outer wall of the outer tube body 620, and the airflow connecting pipe 621 is connected to the accommodating area 630; the air supply pipe 9 is arranged along the first sewage pipe 5, passes through the sewage barrel 2 and the first filter element 3, and is connected to the airflow connecting pipe 621.

[0057] The air supply pipe 9 connected to the airflow pipe 621 and the air supply pipe 9 connected to the oxygen explosion pipe 10 can be two independent pipes. In some embodiments, one pipe can be connected to a three-way splitter to separate two air supply pipes 9, which are then connected to the airflow pipe 621 and the oxygen explosion pipe 10 respectively.

[0058] The power device 6 of this structure is quieter than a noisy water pump, which avoids scaring the shrimps. In addition, the flow rate of the inner tube body 610 is larger, which can ensure the integrity of the shrimp shells and avoid them being broken by the pump and causing pollution.

[0059] Please refer to Figure 5The separation container 8 is provided with a living body return pool gap 830 , and the living body return pool gap 830 is provided between the upper end opening of the separation container 8 and the third filtering gap 820 .

[0060] Some live shrimps may unfortunately be sucked through the second filter gap 410 and mistakenly enter the separation container 8. Then, the live shrimps entering the storage chamber 810 can pass through the live return gap 830, leave the separation container 8, and return to the pool basin 1.

[0061] Please refer to Figure 5 , including an overflow pipe 11; the overflow pipe 11 is connected to the separation container 8, one end of which extends out from the lower end of the bottom wall of the separation container 8, and the other end extends into the receiving cavity 810; and the end of the overflow pipe 11 extending into the receiving cavity 810 has an opening height higher than the outlet height of the second sewage pipe 7. The end of the overflow pipe 11 extending into the receiving cavity 810 has a tooth-shaped ring edge 1110.

[0062] When the storage chamber 810 of the separation container 8 contains more and more shrimp shells or other debris, the third filter gap 820 may be blocked, and the water discharged from the outlet of the second sewage pipe 7 may remain in the storage chamber 810, causing the water level in the storage chamber 810 to become higher and higher. The shrimp shells and debris in the storage chamber 810 float with the rising water level, and the water level, shrimp shells and debris exceed the height of the upper opening and flow back into the pool basin 1.

[0063] By providing an overflow pipe 11, the water can be discharged back into the pool 1 through the overflow pipe 11 to prevent the water level from rising continuously. The tooth-shaped ring edge 1110 can intercept shrimp shells or other debris, and at the same time facilitate the water to flow through the gaps between the teeth and flow back into the pool. The design is ingenious and saves water resources well.

[0064] Please refer to Figure 3 and Figure 4 The first filter element 3 is disc-shaped as a whole, and has an inclined depression from the edge to the center toward the bottom wall of the sewage barrel 2; the first filter element 3 is provided with a plurality of vortex grilles 320 formed by the first filter element 3 from the edge to the center to form a vortex shape, and a spiral groove is provided between two adjacent vortex grilles 320, and the vortex grilles 320 and the spiral groove rotate in the same direction.

[0065] Please refer to Figure 3 and Figure 4 , Figure 6 The second filter element 4 is a tube body, and the second filter gap 410 is arranged on the side wall of the tube body; the first filter element 3 is provided with a avoidance through hole corresponding to the second filter element 4; the avoidance through hole is ring-shaped around the outer wall of the second filter element 4; the water-facing side of the vortex grille 320 is provided with a blade tip.

[0066] Preferably, the second filter element 4 and the power device 6 are an integral structure.

[0067] Please refer to Figure 1 and Figure 6 , including a support frame 12 and a lifting device 13. The support frame 12 is used to set up the lifting device 13 on the pool basin 1. The power output end of the lifting device 13 is connected to the second filter element 4, which is used to drive the second filter element 4 to move relative to the first filter element 3 and adjust the size of the second filter gap 410.

[0068] The support frame 12 is used to set up a protective cover, which can be opened and closed to seal the pool basin 1, effectively preventing debris or birds from entering to eat and pollute the pool water.

[0069] The lifting device 13 drives the second filter element 4 to approach the sewage barrel 2. The more the second filter element 4 disposed on the side wall of the lower end of the second filter element 4 passes through the avoidance hole and enters the cavity 220, the smaller the size of the second filter gap 410 formed by the second filter element 4 and the first filter element 3; conversely, the larger the size of the second filter gap 410. Therefore, the breeding pond can be adapted to the growth and size of the shrimps by means of this flexible and dynamic adjustment.

[0070] In some embodiments, the lifting device 13 includes a motor suspended on the support frame 12, the motor power output shaft is connected to a threaded rod 1310, the outer wall of the second filter element 4 is connected to a bracket 1320, and the bracket is provided with a screw nut 1330 that cooperates with the threaded rod 1310.

[0071] In some embodiments, the basin body of the pool 1 is made of impact-resistant PP material injection-molded into a pool body, which is composed of multiple boards, and the alignment interface between the panels is designed with double sealing and water-proof buckles, which are tightly combined and can be assembled on any flat ground. It has the advantages of easy assembly, disassembly, transfer and transportation, and the plastic board has good corrosion resistance, is not easy to age, is environmentally friendly and non-toxic.

[0072] The sewage bucket 2 and the first filter element 3 are also made of PP material and are located at the lowest point in the middle of the pool basin 1. The PP material board has the advantage of a smooth surface, which can effectively slide dirt and impurities to the first filter element 3 at the lowest point in the middle, and separate shrimp feces and shrimp shell debris on the mesh surface of the first filter element 3.

[0073] Shrimp feces and finer debris flow into the chamber 220 through the mesh of the first filter gap 310 and are discharged by the first sewage pipe 5. Shrimp shells, dead shrimps and large debris slide down the inclined surface of the first filter element 3 to the second filter gap 410 at the bottom periphery of the second filter element 4 in the middle, and are sucked away and filtered by the self-priming separator system of the power device 6, so that the water in the pool remains clean for a long time.

[0074] The sewage barrel 2 with a simple structure of a sewage inlet 210, a cavity 220, and a sewage outlet 230 is preferably in an elbow shape, and the sewage inlet 210, the cavity 220, and the sewage outlet 230 are connected by a smooth arc surface transition without dead corners and without hiding dirt or feces.

[0075] In the specification and claims of the present application, the words "include / comprise" and the words "have / include" and their variations are used to specify the existence of stated features, values, steps or components, but do not exclude the existence or addition of one or more other features, values, steps, components or combinations thereof.

Conversely, some features of the present invention are described in a single embodiment for brevity, however, these features may also be described in different embodiments alone or in any suitable combination.
