[0002] As a kind of fish with high economic value, the aquaculture of grouper occupies an important position in the aquaculture industry. In the natural environment, extreme weather such as heavy rain may cause the water level in the aquaculture pond to rise sharply. If the drainage is not timely, too high water level may cause the grouper to escape, bringing huge economic losses to farmers.

[0003] After retrieval, a drainage device for fishery aquaculture with the publication number CN207355272U includes a drainage structure and a guide rod. The drainage structure includes a horizontally arranged drain pipe. The right end of the drain pipe is connected with a folding pipe. One end of the folding pipe is provided with a connecting pipe. The other end of the folding pipe is fitted with a first connecting pipe. A flange is connected between the connecting pipe and the drain pipe. The end of the first connecting pipe away from the folding pipe has a convex edge. The first connecting pipe is fitted with a ring part through the convex edge. The top of the ring part has a hemispherical filter net cover. An activity ring is connected to the outer wall of the first connecting pipe. Water enters through the position of the filter net cover in this device, and the water is discharged to the drainage channel. The filter net cover can prevent fish from passing through, avoiding losses to farmers while maintaining the water level line. At the same time, the height of the filter net cover in this device is adjustable, so the water level in the pond can be fixed as needed, and the excess water can be discharged.

[0004] Based on the above patent, in the background art mentioned, during the process of fishery aquaculture, heavy rain weather often occurs. In order to avoid the rise of the water level in the pond, the existing treatment method is to manually open the drainage outlet on rainy days. However, fish often escape through the drainage outlet, causing losses to farmers. And after the drainage outlet is opened, it needs to be blocked, and the operation is relatively troublesome. In view of this technical problem, this application proposes a drainage device for grouper aquaculture. Content of the Utility Model

[0023] Specifically, the filter nets 4 on the water outlet pipes 3 can prevent grouper from escaping, but after long-term use, they will be covered by fish feces or feed residues, resulting in unsmooth drainage. At this time, the electric push rod 9 can be started to drive the connecting plate 10 to move, the connecting plate 10 drives the first toothed plates 11 on both sides to move, and the first toothed plates 11 drive the toothed rings 12 to rotate, thereby driving the water outlet pipes 3 to rotate, and then driving the filter nets 4 to rotate.

The second bevel gears 16 drive the rotating shafts 17 to rotate, and the rotating shafts 17 drive the lifting gears 18 to rotate. The lifting gears 18 rotate and rise on the second toothed plates 19, thereby driving the lifting plates 2 to rise, and further driving the water outlet pipes 3 to rise, so that the water outlet pipes 3 reach the appropriate drainage positions, drain the excess water. The filter screens 4 on the water outlet pipes 3 will be covered by fish feces or feed residues after long-term use, resulting in unsmooth drainage.
