Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 , figure 2 As shown, the present invention comprises elbow 1, drain pipe A2, drain pipe B3, pinch plate 4, live shrimp anti-escape tooth 5 and chassis 6, wherein the two ends of elbow 1 are respectively connected with one end of drain pipe B3 and drain pipe A2 The other end of the drainage pipe B3 passes through the threaded hole provided on the pinch plate 4, and the end is connected with the chassis 6, and the other end of the drainage pipe B3 is uniformly provided with a plurality of through holes 8 along the circumferential direction; in this embodiment The elbow 1 is a right-angle elbow, and the axial centerline of the drainage pipe A2 is perpendicular to the axial centerline of the drainage pipe B3.

[0020] An external thread section 10 is arranged on the outer surface between the two ends of the drainage pipe B3, and the thr...

Abstract

The invention belongs to the field of aquaculture engineering, and specifically relates to a bottom sewage discharge device for a turntable shrimp pond with adjustable pores. The other end of the drain pipe B is passed through the threaded hole opened on the pinch plate, and the end is connected to the chassis. The other end of the drainage pipe B is provided with a through hole; Through the threaded hole and the external thread section to form a spiral pair; the chassis is placed on the bottom of the shrimp pond, through the spiral pair between the pinch plate and the external thread section, the pinch plate is rotated to realize the lifting of the pinch plate relative to the drainage pipe B, and then adjust the pinch The size of the sewage suction hole formed between the lower end of the outer edge of the plate and the bottom surface of the shrimp pond; the outer edge of the pinch plate is provided with live shrimp anti-escaping teeth to prevent live shrimp from close contact with the sewage suction hole. The invention can conveniently adjust the sewage suction pores at the bottom of the shrimp culture pond according to the specifications of the live shrimp, which is beneficial to the discharge of the dirt and prevents the live shrimp from escaping.

Description

technical field [0001] The invention belongs to the field of aquaculture engineering, in particular to a bottom sewage discharge device for a turntable shrimp pond with adjustable pores. Background technique [0002] In order to efficiently discharge dirt such as shrimp shells, dead shrimp, and residual bait feces during the prawn breeding process, an intermittent return water process (such as disclosed on September 22, 2017, the publication number is CN107182893A, and the invention name is "a circulating water Intermittent return water device and its return water process for aquaculture system"). When adopting this technology to raise shrimps, when the intermittent return water is turned on, the live shrimps will be sucked out into the live shrimp escape prevention basket along with the shrimp shells and dirt due to the strong suction of the sewage suction port (see 2019 for the live shrimp escape prevention basket) It was published on March 12, 2010, the publication numbe...
