Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, specifically to a water-circulating independent aquaculture equipment. Background Technology

[0002] Currently, there are two types of aquaculture: outdoor extensive aquaculture and indoor low-water-level factory aquaculture. Both are generally carried out in a manner that mimics the natural environment.

[0003] Extensive searches revealed CN209073266U, which discloses a water circulation device for aquaculture. The device involves extending an inlet pipe into the pond bottom and vertically arranging overflow pipes, allowing clean water to be uniformly added from a large area at the bottom, thus renewing the water quality. The overflow pipes are suspended from the pond bottom silt by floats and ropes, preventing blockage and turbidity caused by the silt. A protective net is installed on the inner side of the drainage trough to prevent aquatic organisms from flowing out.

[0004] Currently, factory farming generally suffers from severe water pollution. While existing technologies have improved the water quality of fish ponds through technical modifications, thus increasing the water quality renewal effect and reducing water consumption, it is difficult to effectively clean up fish excrement and debris that sink to the bottom of the water body during actual use. Therefore, an independent water circulation aquaculture device is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an independent water circulation aquaculture device that has the advantage of cleaning sediment and debris from the bottom of the aquaculture pond, thus solving the problem that existing devices are difficult to clean the bottom of the pond.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water circulation independent aquaculture equipment, including an aquaculture pond, a filter mechanism fixedly installed on one side of the aquaculture pond, the aquaculture pond including a cylinder, a first bottom shell fixedly installed in the middle of the inner side of the cylinder, and a second bottom shell fixedly installed at the bottom of the inner side of the cylinder;

[0007] The first bottom shell adopts a funnel-shaped structure design. A second filter screen is fixedly installed at the bottom of the first bottom shell with an opening. The second filter screen adopts a conical structure design. A sealing plug is movably installed at the bottom of the second filter screen.

[0008] The second bottom shell adopts a funnel-shaped structure design. A reserved groove is opened in the middle of the bottom of the second bottom shell. An installation plate is fixedly installed at the bottom of the reserved groove. A cylinder is embedded in the middle of the upper surface of the installation plate. The top of the cylinder is fixedly connected to the bottom of the sealing plug.

[0009] Preferably, the filtration mechanism includes a filter box, a first filter screen fixedly installed inside the filter box, and a connecting pipe installed through an opening at the bottom of the filter box. The bottom end of the connecting pipe passes through one side of the second bottom shell, and the bottom of the inner wall of the connecting pipe is flush with the bottom of the inner wall of the second bottom shell. In this design, the filter box and the first filter screen in the filtration mechanism effectively filter the water in the aquaculture pond. The filter box allows the water to pass through the first filter screen during circulation, removing impurities and particulate matter and improving the cleanliness of the water. Simultaneously, the filtered water can flow smoothly back to the aquaculture pond, forming a closed-loop water circulation system.

[0010] Preferably, the mesh size of the first filter screen is smaller than that of the second filter screen, and a discharge pipe is provided on the front of the filter box below the first filter screen, with a sealing cap threaded onto the discharge pipe. By setting the mesh size of the first filter screen to be smaller than that of the second filter screen, impurities at the bottom of the pool can pass through the second filter screen but not the first. Simultaneously, the discharge pipe allows impurities in the filter box to be easily discharged, facilitating equipment maintenance and cleaning.

[0011] Preferably, a circulation pump is fixedly installed on the connecting pipe, and the connecting pipe is made of stainless steel. The circulation pump fixedly installed on the connecting pipe provides the power for water circulation, ensuring the normal operation of the water circulation system. The circulation pump allows the water to continuously circulate between the aquaculture tank and the filtration mechanism, thereby improving the water renewal rate and cleanliness. Furthermore, the stainless steel design of the connecting pipe has advantages such as corrosion resistance and wear resistance, ensuring the long-term stable operation of the equipment.

[0012] Preferably, a fixing frame is fixedly installed on the outer side of the cylinder, and a support frame is fixedly installed in a circular array at the bottom of the fixing frame. The cylinder is fixedly connected to the filter box through the fixing frame, and an opening is made at the connection between the cylinder and the filter box, communicating with the interior of the filter box above the first filter screen. The design, through the setting of the fixing frame and the support frame, achieves a stable connection and support between the aquaculture pond and the filtration mechanism. The circular array design of the fixing frame and the support frame makes the overall structure of the equipment more stable and able to withstand greater external forces and pressures. At the same time, the design of the opening at the connection between the cylinder and the filter box, communicating with the interior of the filter box above the first filter screen, ensures that the water filtered by the filtration mechanism can smoothly enter the cylinder.

[0013] Preferably, the sealing plug is made of soft rubber and has a conical top. The top of the sealing plug contacts but is not fixedly connected to the second filter screen and the first bottom shell. The soft rubber material provides good elasticity and sealing performance. The conical top ensures a tighter contact with the second filter screen and the first bottom shell, effectively preventing water leakage and impurities from entering the second bottom shell. Furthermore, the design of contacting but not fixing the sealing plug to the second filter screen and the first bottom shell allows for easy raising and lowering of the sealing plug when needed, facilitating the removal of debris from the bottom of the tank. This design ensures both the sealing performance of the equipment and improves its flexibility and practicality.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] In this invention, the aquaculture pond is divided into two parts. The first and second bottom shells effectively separate the water and sediment. The first bottom shell has a funnel-shaped structure with a second filter screen fixedly installed at its bottom. This allows fish excrement and sediment to settle at the bottom of the first bottom shell, while a sealing plug at the bottom of the second filter screen prevents these debris from directly entering the second bottom shell. The second bottom shell also has a funnel-shaped structure with a pre-drilled groove in the middle of its bottom. A mounting plate is fixedly installed at the bottom of the groove, and a cylinder is embedded in the mounting plate. The top of the cylinder is fixedly connected to the bottom of the sealing plug, allowing the sealing plug to move up and down by extending and retracting the cylinder. When sediment needs to be cleaned, the cylinder pulls the sealing plug down, separating it from the second filter screen. At this point, the sediment and fish excrement settled at the bottom of the first bottom shell can pass through the second filter screen and enter the second bottom shell. By activating the circulation pump in the filtration mechanism, the water in the aquaculture pond is drawn into the filtration mechanism for filtration, removing impurities and particulate matter. Because the bottom end of the connecting pipe passes through one side of the second bottom shell and the bottom of the inner wall of the connecting pipe is flush with the bottom of the inner wall of the second bottom shell, debris and water inside the second bottom shell can be drawn into the filtration mechanism together. The filtered water flows back into the aquaculture pond, forming a closed-loop water circulation system. After the water has circulated for a period of time, the cylinder is activated again, causing the sealing plug to rise and seal the bottom of the first bottom shell. At this point, the circulation pump can be turned off, stopping the water circulation. Then, the sealing cover on the discharge pipe of the filtration mechanism can be opened to clean the inside of the filter box, thereby effectively cleaning the debris at the bottom of the aquaculture pond. In summary, through the design of this utility model, effective cleaning of sedimented debris in the aquaculture pond is achieved, solving the problem that existing devices are difficult to use for bottom cleaning. This design not only improves the efficiency of aquaculture equipment but also helps maintain the cleanliness of the water in the aquaculture pond, providing a better growth environment for aquaculture.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of the present invention is provided: a water circulation independent aquaculture equipment, including an aquaculture pond 1, a filter mechanism 2 fixedly installed on one side of the aquaculture pond 1, the aquaculture pond 1 including a cylinder 11, a first bottom shell 13 fixedly installed in the middle of the inner side of the cylinder 11, and a second bottom shell 14 fixedly installed at the bottom of the inner side of the cylinder 11.

[0024] The first bottom shell 13 adopts a funnel-shaped structure design. The bottom of the first bottom shell 13 has an opening and a second filter screen 3 is fixedly installed. The second filter screen 3 adopts a conical structure design. A sealing plug 4 is movably installed at the bottom of the second filter screen 3.

[0025] The second bottom shell 14 adopts a funnel-shaped structure design. A reserved groove 141 is opened in the middle of the bottom of the second bottom shell 14. An installation plate 16 is fixedly installed at the bottom of the reserved groove 141. A hole is opened in the middle of the upper surface of the installation plate 16 and a cylinder 17 is embedded therein. The top of the cylinder 17 is fixedly connected to the bottom of the sealing plug 4.

[0026] Specifically, the aquaculture pond 1 is divided into two parts. The first bottom shell 13 and the second bottom shell 14 effectively separate the water and sediment. The first bottom shell 13 has a funnel-shaped structure and a second filter screen 3 is fixedly installed at its bottom. This allows fish excrement and sediment to settle at the bottom of the first bottom shell 13, while the sealing plug 4 at the bottom of the second filter screen 3 prevents these debris from directly entering the second bottom shell 14. The second bottom shell 14 also has a funnel-shaped structure and a pre-reserved groove 141 in the middle of its bottom. An installation plate 16 is fixedly installed at the bottom of the pre-reserved groove 141, and a cylinder 17 is embedded in the installation plate 16. The top of the cylinder 17 is fixedly connected to the bottom of the sealing plug 4, so that the extension and retraction of the cylinder 17 can drive the sealing plug 4 to move up and down. When it is necessary to clean the sediment, cylinder 17 pulls the sealing plug 4 downward, separating it from the second filter screen 3. At this time, the sediment and fish excrement deposited at the bottom of the first bottom shell 13 can pass through the second filter screen 3 and enter the second bottom shell 14. By activating the circulation pump 23 in the filtration mechanism 2, the water in the aquaculture pond 1 is pumped into the filtration mechanism 2 for filtration, removing impurities and particulate matter. Since the bottom end of the connecting pipe 24 passes through one side of the second bottom shell 14 and the bottom of the inner wall of the connecting pipe 24 is flush with the bottom of the inner wall of the second bottom shell 14, the sediment and water in the second bottom shell 14 can be pumped into the filtration mechanism 2 together. The filtered water flows back into the aquaculture pond 1, forming a closed-loop water circulation system. After the water has circulated for a period of time, cylinder 17 is activated again, causing the sealing plug 4 to rise and seal the bottom of the first bottom shell 13. At this time, the circulation pump 23 can be turned off to stop the water circulation. Then, the sealing cover 211 on the discharge pipe of the filter mechanism 2 can be opened to clean the inside of the filter box 21, thereby effectively cleaning the debris at the bottom of the aquaculture pond 1. In summary, through the design of this utility model, effective cleaning of sediment at the bottom of the aquaculture pond 1 is achieved, solving the problem that existing devices are difficult to use for bottom cleaning. This design not only improves the efficiency of aquaculture equipment but also helps maintain the cleanliness of the water in the aquaculture pond 1, providing a better growth environment for aquaculture.

[0027] Example 2

[0028] In order to achieve effective water filtration and water circulation, such as Figure 2 and Figure 3 , Figure 4As shown, in this embodiment, the filtration mechanism 2 includes a filter box 21. A first filter screen 22 is fixedly installed inside the filter box 21. The bottom of the filter box 21 has an opening and a connecting pipe 24 is installed therethrough. The bottom end of the connecting pipe 24 passes through one side of the second bottom shell 14, and the bottom of the inner wall of the connecting pipe 24 is flush with the bottom of the inner wall of the second bottom shell 14. In this design, the filter box 21 and the first filter screen 22 in the filtration mechanism 2 effectively filter the water in the aquaculture pond 1. The filter box 21 allows the water to pass through the first filter screen 22 during circulation, removing impurities and particulate matter and improving the cleanliness of the water. At the same time, the filtered water can flow smoothly back to the aquaculture pond 1, forming a closed-loop water circulation system.

[0029] Furthermore, the mesh size of the first filter screen 22 is smaller than that of the second filter screen 3. A discharge pipe is located on the front of the filter box 21 below the first filter screen 22, and a sealing cap 211 is threaded onto the discharge pipe. By setting the mesh size of the first filter screen 22 to be smaller than that of the second filter screen 3, impurities at the bottom of the pool can pass through the second filter screen 3 but not the first filter screen 22. Simultaneously, the discharge pipe allows impurities within the filter box 21 to be easily discharged, facilitating equipment maintenance and cleaning.

[0030] Furthermore, a circulation pump 23 is fixedly installed on the connecting pipe 24, which is made of stainless steel. The circulation pump 23 fixedly installed on the connecting pipe 24 provides the power for water circulation, ensuring the normal operation of the water circulation system. The circulation pump 23 allows the water to continuously circulate between the aquaculture tank 1 and the filtration mechanism 2, thereby improving the water renewal speed and cleanliness. In addition, the stainless steel design of the connecting pipe 24 has advantages such as corrosion resistance and wear resistance, ensuring the long-term stable operation of the equipment.

[0031] Furthermore, a fixing frame 12 is fixedly installed on the outside of the cylinder 11, and a support frame 15 is fixedly installed in a ring array at the bottom of the fixing frame 12. The cylinder 11 is fixedly connected to the filter box 21 through the fixing frame 12. An opening is made at the connection between the cylinder 11 and the filter box 21, which communicates with the interior of the filter box 21 above the first filter screen 22. In this design, the fixing frame 12 and the support frame 15 achieve a stable connection and support between the aquaculture pond 1 and the filtration mechanism 2. The ring array design of the fixing frame 12 and the support frame 15 makes the overall structure of the equipment more stable and able to withstand greater external forces and pressures. At the same time, the design of the opening at the connection between the cylinder 11 and the filter box 21, which communicates with the interior of the filter box 21 above the first filter screen 22, ensures that the water filtered by the filtration mechanism 2 can smoothly enter the cylinder 11.

[0032] Furthermore, the sealing plug 4 is made of soft rubber and features a conical top. The top of the sealing plug 4 contacts but is not fixedly connected to the second filter screen 3 and the first bottom shell 13. The soft rubber material provides excellent elasticity and sealing performance. The conical top of the sealing plug 4 ensures a tighter contact with the second filter screen 3 and the first bottom shell 13, effectively preventing water leakage and impurities from entering the second bottom shell 14. Simultaneously, the design of the sealing plug 4 contacting but not being fixedly connected to the second filter screen 3 and the first bottom shell 13 allows for easy raising and lowering when needed, facilitating the removal of debris from the bottom of the tank. This design ensures both the sealing performance of the equipment and enhances its flexibility and practicality.

[0033] When using this invention, if it is necessary to clean the debris at the bottom of the aquaculture pond 1, first ensure that the circulation pump 23 is not started, and start the cylinder 17 to move the sealing plug 4 down, thereby separating the sealing plug 4 from the first filter screen 22. Then, the debris and fish excrement at the bottom of the pond can pass through the second filter screen 3 and enter the second bottom shell 14. At this time, turn on the circulation pump 23 to allow the water in the aquaculture pond 1 to enter the filtration mechanism 2 through the connecting pipe 24. The water in the filtration mechanism 2 is filtered by the first filter screen 22 to remove larger impurities and particles. The filtered water flows back to the aquaculture pond 1 to form a cycle. After the water has circulated for a period of time, start the cylinder 17. Under the push of the cylinder 17, the sealing plug 4 rises and seals the first bottom shell 13. Then, turn off the circulation pump 23 to stop the water circulation and open the sealing cover 211 to clean the inside of the filter box 21.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
