DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: an oxygenation device for a koi fry breeding pond, comprising a breeding pond 1, a plurality of fixed columns 2 are fixedly connected to the top of the breeding pond 1, a water changing tank 3 is fixedly connected between the tops of the plurality of fixed columns 2, an oxygenation mechanism is arranged inside the water changing tank 3, a drainage mechanism is arranged at the bottom of the water changing tank 3, a water changing mechanism is arranged between the side end of the breeding pond 1 and the side end of the water changing tank 3, water with thin oxygen in the breeding pond 1 can be pumped into the water changing tank 3 through the water changing mechanism, air oxygen is injected into the water with thin oxygen through the oxygenation mechanism to increase oxygen, and the oxygenated water is discharged into the breeding pond 1 through the setting of the drainage mechanism, so that the water in the breeding pond 1 can be circulated and changed, so as to avoid the koi fish from being suffocated by lack of oxygen and improving the survival rate of the koi fish, and at the same time, because the oxygenation mechanism is arranged in the water changing tank 3, the water will not contact with the koi fish when oxygenating, so as to avoid the koi fish from contacting the oxygenation mechanism and causing casualties, and thus avoiding economic losses to the breeder.

[0021] Furthermore, a plurality of chutes 101 are provided at the inner side end of the breeding pond 1, and a filtering mechanism is provided between the plurality of chutes 101, the filtering mechanism comprising a filter plate 5, the filter plate 5 being located inside the breeding pond 1, a plurality of sliders 501 being fixedly connected to the side end of the filter plate 5, each slider 501 being slidably connected in each chute 101, a pull rod 502 being fixedly connected to the top of each slider 501, and a handle being fixedly connected to the top of each pull rod 502. Due to the provision of the filter plate 5, koi fish are cultured on the top of the filter plate 5, and the feed sprinkled by the farmer and the excrement of the koi fish can be filtered, thereby facilitating the subsequent cleaning of the feed and excrement, and the filter plate 5 can be disassembled by pulling the handle and the pull rod 502 upwards, thereby facilitating the cleaning of the feed and excrement on the filter plate 5.

[0022] As an implementation method in this embodiment, Figure 1 As shown, the oxygenation mechanism includes a motor 4, which is fixedly mounted on the outer side end of the water change tank 3, and a rotating rod 401 is mounted on the output end of the motor 4, which extends to the inner side end of the water change tank 3, and the side end of the rotating rod 401 is rotatably arranged on the inner side end of the water change tank 3, and a plurality of impellers 402 are fixedly connected to the outer end of the rotating rod 401. In implementation, the oxygenation mechanism is arranged inside the water change tank 3, and the rotating rod 401 and the impeller 402 are driven to rotate by starting the motor 4. At this time, the impeller 402 stirs the water in the water change tank 3, so that the water in the water change tank 3 is injected with air oxygen, thereby achieving the effect of oxygenation for water with low oxygen content.

[0023] As an implementation method in this embodiment, Figure 2 As shown, the drainage mechanism includes an outlet pipe 6, which is fixedly connected to the bottom end of the water changing tank 3, a valve 603 is installed between the inside and the outside of the outlet pipe 6, and a diverter plate 601 is fixedly connected to the bottom end of the outlet pipe 6. A plurality of water outlets 602 are provided at the side end of the diverter plate 601. During implementation, by opening the valve 603, oxygen-filled water is allowed to flow from the water changing tank 3 through the outlet pipe 6, into the diverter plate 601, and finally flows out from each water outlet 602. At this time, it will be mixed with the water in the breeding pond 1. Since the flowing water flows downward through the water outlet 602 and contacts with the air again, the water mixed with the breeding pond 1 can be oxygenated again, thereby avoiding the situation of hypoxia and suffocation of koi fish and improving the survival rate of koi fish.

[0024] As an implementation method in this embodiment, Figure 2 and Figure 4As shown, the water exchange mechanism includes a pump 7, which is fixedly installed at the side end of the culture pond 1. An input pipe is installed at the input end of the pump 7, and the input pipe extends to the inner bottom end of the culture pond 1. The filter plate 5 is located at the top of the input pipe. An output pipe 701 is installed at the output end of the pump 7, and the output pipe 701 is fixedly installed to the inner side end of the water exchange tank 3. The pipe mouth of the output pipe 701 is threadedly connected with a filter screen 702. The filter screen 702 can be easily disassembled by rotating the filter screen 702, so as to facilitate cleaning of the feed and excrement on the filter screen 702. In practice, the water in the culture pond 1 is pumped into the output pipe through the input pipe by the pump 7. The water in the water exchange tank 3 is stirred by the impeller 402 so that the water in the water exchange tank 3 is injected with air oxygen, thereby achieving the effect of increasing oxygen. After opening the valve 603, the oxygen-filled water flows from the water exchange tank 3 through the outlet pipe 6 to the diverter plate 601, and finally flows out from each water outlet 602. At this time, it will be mixed with the water in the breeding pond 1, so that the water in the breeding pond 1 can be circulated and replaced, thereby avoiding the situation of hypoxia and suffocation of koi fish and improving the survival rate of koi fish.

[0025] Working principle: The water in the culture pond 1 is pumped into the output pipe 701 through the input pipe by the pump 7. At this time, the water with low oxygen in the culture pond 1 can be replaced in the water exchange tank 3. At this time, the oxygenation mechanism is arranged in the water exchange tank 3. At this time, the motor 4 is started to drive the rotating rod 401 and the impeller 402 to rotate. At this time, the impeller 402 stirs the water in the water exchange tank 3, so that the water in the water exchange tank 3 is injected with air oxygen, thereby achieving the effect of oxygenation. Then, the valve 603 is opened to allow the water full of oxygen to flow from the water exchange tank 3 through the outlet pipe 6 to the diverter plate 601. After that, it flows out from each water outlet 602, where it will mix with the water in the breeding pond 1. Since the water flows downward through the water outlet 602 and contacts with the air again, the water mixed with the water in the breeding pond 1 can be oxygenated again, thereby facilitating the circulation of water in the breeding pond 1, thereby preventing the koi fish from suffocating due to lack of oxygen and improving the survival rate of the koi fish. At the same time, since the oxygenation mechanism is arranged in the water exchange tank 3, the water will not contact the koi fish when it is oxygenated, thereby preventing the koi fish from contacting the impeller 402 and causing casualties, thereby avoiding economic losses to the breeder.

[0026] Due to the setting of the filter plate 5, the koi fish are raised on the top of the filter plate 5, and the feed scattered by the breeder and the excrement of the koi fish can be filtered, so that the water drawn into the output pipe 701 by the input pipe is filtered water, and then the drawn water is filtered again after passing through the filter screen 702, so that the oxygenated water in the water exchange tank 3 is cleaner and more hygienic, and the filter plate 5 can be disassembled by pulling the handle and the pull rod 502 upwards, so as to facilitate cleaning of the feed and excrement on the filter plate 5, and the filter screen 702 can be disassembled by rotating the filter screen 702, so as to facilitate cleaning of the feed and excrement on the filter screen 702.

[0027] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
