[0042] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0043] See also Figure 1 to Figure 3 , this embodiment provides a breeding pond, including a breeding system, a water inlet system, and a drainage system.
[0044] The breeding system includes a first fish pond 11 and a second fish pond 12 , and water in the first fish pond 11 can overflow into the second fish pond 12 .
[0045] The water inlet system includes an inlet culvert 21, a water storage sedimentation tank 32122 and an inlet channel 23 which are connected in sequence. The inlet end of the inlet culvert 21 is connected to the natural river 4. The water storage sedimentation tank 32122 plays a certain role in purifying water. The inlet channel 23 is arranged along the edge of the first fish pond 11 and the second fish pond 12, and the inlet channel 23 is connected to the first fish pond 11 and the second fish pond 12.
[0046] The drainage system includes a drainage channel 31, an ecological treatment pool, a water return channel 33 and a water return channel 34, wherein the drainage channel 31, the ecological treatment pool and the water return channel 33 are connected in sequence.
[0047] One end of the drainage channel 31 is located in the first fish pond 11, and the other end is connected to the ecological treatment pond after passing through the second fish pond 12. The drainage channel 31 has a rectangular cross section, and the drainage channel 31 is divided into an upper drainage channel 312 and a lower drainage channel 313 by a partition 311.
[0048] The upper drainage channel 312 is used to drain the upper water of the first fish pond 11 and the second fish pond 12 . Specifically, a drainage weir 314 is provided on the side wall of the upper drainage channel 312 , and the upper water of the first fish pond 11 and the second fish pond 12 enters the upper drainage channel 312 from the drainage weir 314 .
[0049] The lower drainage channel 313 is used to drain the lower water and impurities of the first fish pond 11 and the second fish pond 12 . Specifically, a drainage port 315 is provided on the side wall of the lower drainage channel 313 , and the lower water and impurities of the first fish pond 11 and the second fish pond 12 enter the lower drainage channel 313 from the drainage port 315 .
[0050] In a specific implementation scenario, the drainage channel 31 adopts a C25 reinforced concrete structure, and the drainage channel 31 is 2.5 to 4.0 meters wide and 4.0 to 4.29 meters high.
[0051] The ecological treatment pool includes a sedimentation pool 321 and a purification pool 322; the sedimentation pool 321, the purification pool 322 and the water return channel 33 can be connected in sequence. A connecting gate 325 is provided between the sedimentation pool 321 and the purification pool 322, and the water in the sedimentation pool 321 can enter the purification pool 322 after the gate is opened.
[0052] A sedimentation tank discharge port 323 is provided on one side of the sedimentation tank 321 , and the sedimentation tank discharge port 323 is connected to the water return channel 33 . The sedimentation tank discharge port 323 is provided with a sedimentation tank 321 discharge gate. After the sedimentation tank 321 discharge gate is opened, the water in the sedimentation tank 321 can directly enter the water return channel 33 .
[0053] A purification pool discharge port 324 is provided on one side of the purification pool 322 , and the purification pool discharge port 324 is connected to the water return channel 33 . The purification pool discharge port 324 is provided with a purification pool 322 discharge gate. After the purification pool 322 discharge gate is opened, the water in the purification pool 322 can enter the water return channel 33 .
[0054] When the discharge gate of the sedimentation tank 321 is closed, and the connecting gate 325 and the discharge gate of the purification tank 322 are opened, the water in the drainage channel 31 flows through the sedimentation tank 321, the purification tank 322 and the water return channel 33 in sequence.
[0055] The outlet of the return channel 33 is connected to the natural river 4; the outlet of the return channel 33 is provided with an anti-backflow gate 331 to prevent the water in the natural river 4 from backflowing into the breeding pond.
[0056] In a specific implementation scenario, the water return channel 33 adopts a C25 reinforced concrete structure, and the water return channel 33 is 4 meters wide and 1.5 meters high.
[0057] The return channel 34 is disposed in the first fish pond 11 ; one end of the return channel 34 is connected to the upper drainage channel 312 , and the other end is connected to the inlet channel 23 , and return channel gates 341 are disposed at both ends of the return channel 34 .
[0058] In a specific implementation scenario, the return channel 34 adopts a C25 reinforced concrete structure, and the return channel 34 is 2 meters wide and 1.5 to 1.65 meters high.
[0059] One way a drainage system works is by:
[0060] Open the return channel gate 341, and the upper water of the first fish pond 11 and the second fish pond 12 will merge in the upper drainage channel 312 and then enter the sedimentation tank 321. Open the connecting gate 325, and guide the precipitated water into the purification tank 322 for biochemical treatment to purify the water quality. Then open the discharge gate and the anti-backflow gate 331 of the purification tank 322, and guide the purified water into the natural river 4 through the return channel 33.
[0061] In combination with the above content, this embodiment has at least the following beneficial effects:
[0062] 1. The upper layer water of the first fish pond 11 and the second fish pond 12 has good water quality. This part of the upper layer water is introduced into the inlet channel 23 through the return channel 34 for recycling and reducing water consumption.
[0063] Second, the lower layer water and impurities of the first fish pond 11 and the second fish pond 12 are introduced into the sedimentation tank 321 and the purification tank 322 for treatment, and then discharged through the water return channel 33, which alleviates the pollution problem and is conducive to promoting the sustainable development of aquaculture.
[0064] 3. The height of the lower drainage channel 313 of the drainage canal 31 is relatively low. When the bottom of the sedimentation tank 321 needs to be cleaned, the water discharged from the lower drainage channel 313 can wash away the sediment at the bottom of the sedimentation tank 321 .
[0065] It should be noted that the above-mentioned breeding ponds do not rely on a specific river in nature.
[0066] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be combined with each other at will. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
