[0008] Preferably, the filter holes are a plurality of vertical rectangular holes arranged in the circumferential direction.

[0009] Preferably, the filter holes are a plurality of inclined rectangular holes arranged in the circumferential direction.

[0010] Preferably, the angle of the inclined direction satisfies: being the same as the direction of the vortex generated when water naturally discharges from the bottom through hole of the box body.

[0011] Preferably, the upper part of the cover body is not provided with filtering holes, and the filtering holes are provided in the lower part.

[0012] Preferably, the cover body is provided with reinforcing ribs.

[0013] An aquatic product breeding water tank includes a box body, and the filtering cover for aquatic product breeding is installed in the box body. It further includes:

[0014] A water extraction pipe that can be inserted into the threaded pipe from the upper part of the filtering cover and can be pulled out.

[0024] Figure 2 It is a schematic diagram of the vertical rectangular hole structure of the cover body of the aquatic product breeding water tank of the present utility model.

[0025] Figure 3 It is a schematic diagram of the inclined rectangular hole structure of the cover body of the aquatic product breeding water tank of the present utility model. Detailed Embodiments

[0026] Now, the present utility model will be further described in conjunction with the drawings:

[0027] As Figure 1 shown, a filtering cover for aquatic product breeding includes:

[0028] The cover body 4 is barrel-shaped, with a through hole from top to bottom. A threaded pipe is provided at its bottom. The threaded pipe can pass through the bottom through hole of the box body 6 and can be fixed to the bottom of the box body 6 by a nut 3. Filter holes are provided on the side wall of the cover body 4. The water and aquatic product excreta in the box body 6 can pass through the filter holes and be discharged through the threaded pipe, while the aquatic products cannot pass through the filter holes.

[0029] The filter cover of the utility model can be formed by an injection molding machine, with low cost. The cover body 4 can effectively discharge the breeding sewage in the box body 6, which is very simple.

[0030] Preferably, the shape of the barrel is circular, oval, rectangular or triangular. The circular barrel shape has the advantages of stable structure and convenient mold opening.

[0031] As an embodiment, the filter holes are multiple vertical rectangular holes 42 arranged in the circumferential direction. The rectangular holes have the characteristic of high water passing efficiency.

[0032] As a second embodiment, the filter holes are multiple inclined rectangular holes 43 arranged in the circumferential direction.

[0033] The angle of the inclined direction satisfies: being the same as the direction of the vortex generated when the water naturally discharges from the bottom through hole of the box body 6.

[0034] It should be noted that the earth rotates around its axis. At places outside the equator, an object moves in a circular motion relative to the earth's center, but the center of the circle is not at the earth's center. That is to say, the centripetal force for its circular motion does not coincide with the gravity. It is this centripetal force that generates the vortex.

[0035] The utility model is provided with the inclined rectangular holes 43 to accelerate the discharge speed of the breeding sewage, which is beneficial to improving the sewage discharge efficiency. In addition, the vortex itself can gather excreta, thereby improving the sewage discharge rate and achieving the effect of water conservation.

[0036] In order to reduce the discharge of clean water and discharge the excreta deposited at the bottom of the water tank as much as possible, no filter holes are provided in the upper part of the cover body 4, and filter holes are provided in the lower part, and the sewage at the bottom is discharged first.

[0037] To improve the strength, the cover body 4 is provided with reinforcing ribs 44.

[0038] An aquatic product breeding water tank includes a box body 6. The filter cover for aquatic product breeding is installed in the box body 6, and further includes:

[0039] A water extraction pipe 5, which can be inserted into the threaded pipe from the upper part of the filter cover, and the water extraction pipe 5 can be pulled out;

[0040] A drain pipe 1, which is connected to the threaded pipe through a valve 2.

[0041] The water extraction pipe 5 of the utility model can function as the valve 2. When the water extraction pipe 5 is pulled out and the valve 2 is opened, the water in the water tank is discharged. When the water extraction pipe 5 is plugged in, regardless of whether the valve is open or closed, it can close the water discharge. This operation is more convenient than operating the valve, and the valve can be used as a backup.

[0042] Preferably, the height of the filter cover is lower than the height of the water tank, and the height of the water is usually lower than the height of the filter cover.

[0043] Preferably, the height of the water extraction pipe 5 is higher than the height of the filter cover.
