TECHNICAL FIELD

[0001] The utility model relates to the technical field of domestic fish rearing basin, especially to a domestic fish rearing basin for aquaculture. BACKGROUND

[0002] The domestic fish rearing basin is a traditional fish rearing container, especially suitable for rearing ornamental fish such as goldfish. For example, a domestic aquaculture rearing basin (CN110278906B) is disclosed. The device is moved to a suitable position, and then small fish are placed in the rearing frame for cultivation. After a period of cultivation, the rearing frame is removed by the disassembly mechanism, and the fish in the rearing frame are poured into a pond. Then, the rearing frame is fixed on the first connecting block by the disassembly mechanism, the second sliding block is loosened, and the second sliding block moves outward under the action of the spring, driving the second sliding block to move outward. The first steel wire rope is loosened, and the first connecting block moves downward, driving the rearing frame to move downward and reset. According to the above operation, the next batch of small fish can be cultivated.

[0003] However, when the rearing frame is removed, the fry will temporarily leave the water environment. Although this process may be short, it can cause stress reactions or even death in some fry that are sensitive to oxygen deficiency. During the removal of the rearing frame, the fry may be squeezed together due to gravity. This squeezing can be more severe, especially when the rearing frame is deep or the density of the fry is high. SUMMARY

[0004] The utility model aims at solving the problems in the prior art and provides a domestic fish rearing basin for aquaculture.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a domestic fish rearing basin for aquaculture, comprising a rearing basin, a support is inserted into the bottom of the rearing basin, a hollow frame is fixedly installed on the upper surface of the support and fits the inner wall of the rearing basin near the bottom, a threaded pipe is fixedly installed through the center of the upper surface of the hollow frame, a hollow plate is sleeved on the surface of the threaded pipe, a filter plate is installed in the hollow part of the surface of the hollow plate, the edge of the filter plate extends upward and is lapped with the upper surface of the hollow plate, a nut is threadedly connected to the surface of the threaded pipe, the bottom end of the nut is lapped with the upper surface of the extended edge of one side of the filter plate, a pipeline is installed through the bottom of the rearing basin, and a gate valve is arranged between the top end of the pipeline and the bottom of the rearing basin.

[0006] Preferably, an adjusting bolt is threadedly connected to the inner wall of the threaded pipe, the bottom end of the adjusting bolt extends below the hollow frame and is rotatably connected to a plug-in frame sleeved on the support.

[0007] Preferably, a sealing strip is installed on the upper surface of the insert holder below any of the hollowed-out areas on the surface of the hollowed-out frame, and the sealing strip is inserted into the hollowed-out area on the surface of the hollowed-out frame.
