Return Device for Recirculating Aquaculture System and Water Return Process thereof" disclosed on September 22, 2017) needs to be adopted. When shrimps are cultured by adopting this technology, live shrimps will be sucked out into a live shrimp anti-escape basket (see the live shrimp anti-escape basket in Chinese publication No.
CN109452215A, entitled "Device and Method for Removing Sewage and Preventing
Escape of Live Shrimps from Recirculating Aquaculture System" that is disclosed on
March 12, 2019) along with the shrimps shells, sewage, etc. due to the great suction force at a sewage suction opening at the moment of starting intermittent water return process. Therefore, in a production process, in order to prevent excessive live shrimps from being sucked out from culture tank, it’s desirable to replace a bottom sewage discharge device with different gap sizes, which increases the labor of workers. How to efficiently discharge sewage, such as shrimp shells, dead shrimps, residual bait, feces, etc, in the aquaculture water, and prevent the live shrimps from being discharged together with the sewage is a key technology in a design of a shrimp culture system. The

DETAILED DESCRIPTION OF THE EMBODIMENTS
[18] The present disclosure will be further described below with reference to accompanying drawings.
[19] As shown in FIG. 1 and FIG. 2, the present disclosure includes an elbow 1, a drainage pipeline A 2, a drainage pipeline B 3, a cover plate 4, live shrimp anti-escape teeth 5, and a base plate 6. Two ends of the elbow are respectively communicated with one end of the drainage pipeline B 3 and the drainage pipeline A 2. The other end of the drainage pipeline B 3 passes through a threaded hole formed in the cover plate 4, and is connected to the base plate 6. Multiple through holes 8 are uniformly formed in the other end of the drainage pipeline B 3 in the circumferential direction. The elbow 1 of the embodiment is a right-angled elbow. The axial center line of the drainage pipeline A 2 is perpendicular to the axial center line of the drainage pipeline B 3.
[20] An external thread section 10 is formed on an outer surface between the two ends of the drainage pipeline B 3. The threaded hole of the cover plate 4 is formed at the center thereof. The threaded hole of the cover plate 4 and the external thread section 10 form a screw pair.
[21] The base plate 6 is placed on the bottom surface of the shrimp pond. Through the screw pair between the cover plate 4 and the external thread section 10, the cover plate 4 is rotated, to move up or down relative to the drainage pipeline B 3, thereby forming a moving pair, and in turn adjust the size of a sewage suction gap 7 formed between the lower end of the outer edge of the cover plate 4 and the bottom surface of the shrimp pond. 5 [22] Multiple live shrimp anti-escape teeth 5 are uniformly distributed on the outer edge of the cover plate 4 in the circumferential direction, which can prevent the live shrimps from being in contact with the sewage suction gap 7 at a close distance. The cover plate 4 of the embodiment is a circular plate with the threaded hole arranged in the center. The outer edge of the cover plate 4 extends downwards. The sewage suction gap 7 is formed between a lower end of an extension part of the cover plate and the bottom surface of the shrimp pond. The live shrimp anti-escape teeth 5 are arranged on the outer surface of the extension part, at a position close to the lower end of the extension part.
The live shrimp anti-escape teeth 5 of the embodiment are equal in height and are arranged in horizontal radial manner. The distance between the live shrimp anti-escape teeth 5 and the lower end of the extension part is 3 to 8 mm, and the distance between adjacent live shrimp anti-escape teeth 5 is 15 to 25 mm. One end of each live shrimp anti-escape tooth 5 is connected to the extension part at the outer edge of the cover plate 4, and the other end of each live shrimp anti-escape tooth 5 is a spherical surface.
[23] To facilitates the rotation of the cover plate 4, four traction rings 9 are uniformly welded on the upper surface of the cover plate 4 in the circumferential direction of the embodiment.
[24] The end of the elbow 1 connected to the drainage pipeline B 3, the drainage pipeline B 3, the cover plate 4, and the base plate 6 of the embodiment have a common axial central line.
[25] A working principle of the present disclosure is as follows.
[26] The present disclosure is a bottom sewage discharge device for a shrimp pond, which is used in cooperation with an intermittent water return process and can realize efficient sewage discharge of the shrimp pond.
[27] Ropes are tied to the traction rings 9, and the bottom sewage discharge device of the present disclosure is placed in the shrimp pond, so that the base plate 6 is in contact with the bottom surface of the shrimp pond.
The cover plate 4 is rotated through the ropes and the traction rings 9 outside the shrimp pond, and the cover plate 4 is moved up or down by using the screw pair between the cover plate 4 and the external thread section 10. The size of the sewage suction gap 7 between the lower end of the outer edge of the cover plate 4 and the bottom surface of the shrimp pond is adjusted according to the sizes of the live shrimps in the shrimp pond.
The adjustment range of the sewage suction gap 7 is 0 to 20 mm, which facilitates the discharge of sewage, and prevents the live shrimps from escaping out. sewage enters a space between the cover plate 4 and the bottom surface of the shrimp pond through the sewage suction gap 7, and is then discharged through the through holes 8, the drainage pipeline B 3, the elbow 1, and the drainage pipeline A 2.
