Abstract
Description
Technical Field
[0001] This utility model relates to the field of PP fish pond technology, specifically to a high-efficiency sewage discharge structure for PP fish ponds. Background Technology
[0002] In the existing aquaculture industry, PP fish ponds are widely used due to their advantages such as being lightweight, corrosion-resistant, easy to process and install. However, with the increase in stocking density and the extension of stocking time, more and more impurities accumulate inside the fish ponds. These impurities not only affect the water quality of the fish ponds, but may also become a breeding ground for pathogens, posing a threat to the health of fish. Therefore, how to efficiently remove impurities from fish ponds and maintain the cleanliness of the water has become an urgent problem to be solved.
[0003] Traditional fishpond drainage methods mostly employ bottom or side drainage, but these methods have some shortcomings in practical applications. Although bottom drainage can directly discharge impurities from the bottom, it usually requires manual cleaning, which is labor-intensive and inefficient. While side drainage can handle light pollutants on the water surface, it is ineffective against impurities deposited at the bottom. Therefore, a high-efficiency drainage structure for PP fishponds is proposed to solve the above problems. Utility Model Content
[0004] In view of the shortcomings of the prior art, this utility model provides a high-efficiency sewage discharge structure for PP fish ponds to overcome the deficiencies of the prior art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A high-efficiency sewage discharge structure for PP fish ponds includes a PP fish pond body, an external water pipe installed on the top of the PP fish pond body, the external water pipe being connected to an external water source, the outlet of the external water pipe facing the bottom of the PP fish pond body and maintaining a 60-degree inclination, and a sewage discharge mechanism installed at the bottom of the PP fish pond body.
[0007] The sewage discharge mechanism includes a cylinder fixedly installed at the bottom of the PP fish pond body, the cylinder being located at the center of the PP fish pond body. A circular drain plate located inside the PP fish pond body is fixedly installed at the top of the cylinder. A first drain pipe is fixedly installed at the bottom of the cylinder, and a first valve is installed on the outside of the first drain pipe. A rectangular bottom cover penetrating into the bottom of the PP fish pond body is fixedly installed, located on the right side of the cylinder, and is connected to the PP fish pond body. A cover plate penetrating into the bottom of the inner cavity of the PP fish pond body is rotatably installed, located behind the rectangular bottom cover, and the bottom area of the cover plate is larger than the bottom area of the rectangular bottom cover. A motor is fixedly installed on the outside of the PP fish pond body, and the output end of the motor is fixedly connected to the right side shaft of the cover plate. A second drain pipe is fixedly installed on the right side of the rectangular bottom cover, and the second drain pipe is connected to the top of the first drain pipe. A second valve is installed on the outside of the second drain pipe.
[0008] The beneficial effects of this utility model are as follows: the cover plate is driven by a motor to rotate clockwise, so that it forms an angle with the bottom of the inner cavity of the fish pond. As the water rotates, impurities sink and are blocked by the cover plate before entering the rectangular bottom cover. At this time, the second valve is opened, and with the help of the connection with the first drain pipe, the impurities can be smoothly discharged to the outside, thereby effectively improving the cleaning efficiency of the fish pond. This process ensures the effective collection and discharge of impurities, maintaining a cleaner environment for the fish pond.
[0009] Based on the above technical solution, the present invention can be further improved as follows.
[0010] Furthermore, an isolation net is fixedly installed inside the rectangular base cover, and the isolation net is located above the second drainage pipe.
[0011] Furthermore, a clamp is fixedly installed on the outer side of the PP fish pond body, and a fixing frame is fixedly installed inside the clamp, with the external water pipe fixedly installed inside the fixing frame.
[0012] Furthermore, a No. 3 valve is installed on the outside of the external water pipe.
[0013] Furthermore, a rubber sleeve is fixedly installed inside the side wall of the PP fish tank body, and the rotating shaft of the cover plate is rotatably installed inside the rubber sleeve.
[0014] Furthermore, a limiting block is fixedly installed on the inner wall of the PP fish pond body, and the limiting block is located on the back of the cover plate. Attached Figure Description

[0024] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0025] Example 1, as Figures 1-6 As shown, a high-efficiency sewage discharge structure for a PP fish pond includes a PP fish pond body 1, an external water pipe 2 is provided on the top of the PP fish pond body 1, the external water pipe 2 is connected to an external water source, the outlet of the external water pipe 2 faces the bottom of the PP fish pond body 1 and is tilted at a 60-degree angle, and a sewage discharge mechanism is provided at the bottom of the PP fish pond body 1.
[0026] Specifically, the sewage discharge mechanism includes a cylinder 3 fixedly installed at the bottom of the PP fish pond body 1, with the cylinder 3 located at the center of the PP fish pond body 1. A circular drain plate 4 is fixedly installed at the top of the cylinder 3, located inside the PP fish pond body 1. A first drain pipe 5 is fixedly installed at the bottom of the cylinder 3, and a first valve 6 is installed on the outside of the first drain pipe 5. A rectangular bottom cover 7 is fixedly installed at the bottom of the PP fish pond body 1, penetrating into its interior. The rectangular bottom cover 7 is located on the right side of the cylinder 3, and the rectangular bottom cover 7 is connected to the PP fish pond body 1. A through-connected cover plate 8 is rotatably installed at the bottom of the inner cavity of the PP fish pond body 1, extending to the outside. The cover plate 8 is located behind the rectangular bottom cover 7, and the bottom area of the cover plate 8 is larger than the bottom area of the rectangular bottom cover 7. A motor 9 is fixedly installed on the outside of the PP fish pond body 1, and the output end of the motor 9 is fixedly connected to the right side shaft of the cover plate 8. A second drain pipe 10 is fixedly installed on the right side of the rectangular bottom cover 7, and the second drain pipe 10 is connected to the top of the first drain pipe 5. A second valve 11 is installed on the outside of the second drain pipe 10.
[0027] The flow of water through drain pipe 5 can be controlled by valve 6, and the flow of water through drain pipe 10 can be controlled by valve 11. A circular baffle 4 isolates the top of cylinder 3 to prevent fish from entering the PP fishpond body 1 during drainage. When sewage needs to be discharged, motor 9 drives cover 8 to rotate clockwise, creating an angle between cover 8 and the bottom of the inner cavity of the PP fishpond body 1. As the water rotates, impurities gradually sink and are blocked by cover 8, then enter the rectangular bottom cover 7. At this time, valve 11 can be opened to allow sewage to drain. The connection between drain pipe 10 (number 2) and drain pipe 5 (number 1) allows impurities to be discharged to the outside through drain pipe 5, thereby improving the cleaning efficiency of the fish pond. After the impurities are cleaned, motor 9 drives cover plate 8 to rotate counterclockwise to seal the top of rectangular bottom cover 7. Then, valve 11 (number 2) is closed, and external water pipe 2 continuously supplies water to the inside of PP fish pond body 1. The water inside PP fish pond body 1 passes through circular perforator 4 and enters the inside of cylinder 3 before being discharged to the outside through drain pipe 5, thus forming a certain water circulation, effectively promoting oxygen exchange in the water and providing a better living environment for fish.
[0028] Example 2, as Figure 1 and Figure 3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0029] An isolation net 12 is fixedly installed inside the rectangular base cover 7, and the isolation net 12 is located above the second drainage pipe 10.
[0030] This setup, via the installed isolation net 12, prevents fish inside the PP fishpond body 1 from entering the rectangular bottom cover 7 during sewage discharge.
[0031] Example 3, as Figures 4-5 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0032] A clamp 13 is fixedly installed on the outside of the PP fish pond body 1, and a fixing frame 14 is fixedly installed inside the clamp 13. The external water pipe 2 is fixedly installed inside the fixing frame 14.
[0033] With this setup, the fixing bracket 14 is fixed to the outside of the PP fish pond body 1 by the clamp 13. At this time, the fixing bracket 14 can fix the external water pipe 2 above the PP fish pond body 1.
[0034] Example 4, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0035] The external water pipe 2 is equipped with valve 15.
[0036] This setting
[0037] Example 5, as Figures 1-5 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0038] A rubber sleeve 16 is fixedly installed inside the side wall of the PP fish pond body 1, and the rotating shaft of the cover plate 8 is rotatably installed inside the rubber sleeve 16.
[0039] This design, through the installation of the rubber sleeve 16, can prevent water leakage at the connection between the cover plate 8 and the PP fish pond body 1.
[0040] Example 6, as Figures 4-7 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:
[0041] A limiting block 17 is fixedly installed on the inner wall of the PP fish pond body 1, and the limiting block 17 is located on the back of the cover plate 8.
[0042] This configuration limits the rotational position of the cover plate 8 by installing the limit block 17.
[0043] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
