Description

Fry rearing pond auxiliary pollution discharge device

Technical Field

The utility model relates to the field of related products of aquaculture, in particular to an auxiliary blowdown device for a fry rearing pond.

Background

The fry breeding process includes the steps of selecting breeding fishes, successfully impregnating the breeding fishes, hatching the breeding fishes until the breeding fishes are bred, needing an administrator to take careful responsibility, putting the breeding fishes into the breeding fishes, paying attention to growth of the fry and change of the environment all the time, giving timely strain countermeasures, and carrying out successful breeding in a proper treatment mode. Although the time from fry breeding to fingerling breeding is short, the survival rate and physical conditions of the fry breeding have great influence on the breeding effect of the whole fingerling, so that the fry breeding must be carefully treated, most of fish excrement, bait residues and other impurities generated in the breeding process are precipitated to the bottom of the pond, a small amount of fish excrement, bait residues and other impurities flow to the next-stage pond along with water flow, the same sediment is generated in the next-stage breeding pond, and the water quality is different from the first-stage breeding pond. The sediments at the bottom of the pond can pollute the culture water quality, influence the growth of the cultured fishes and influence the meat quality of the cultured fishes.

The sewage draining pump is usually arranged at the bottom of the pool to drain the sewage at the bottom of the pool, however, the situation that the seedlings are drained together with the water flow during the draining process can occur, so that the seedling safety is influenced, the mode cannot effectively remove the bottom of the pool, and the sewage deposited at the bottom of the pool cannot be completely drained.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-5, an embodiment of the present invention is shown: an auxiliary blowdown device for a fry rearing pond comprises an inner sleeve and an outer sleeve, wherein the inner sleeve comprises a water level pipe 1 and a fixed net pipe 2, the outer wall of the lower end of the fixed net pipe 2 is fixed on the inner wall of a sleeve opening in the rearing pond, the water level pipe 1 is arranged in the fixed net pipe 2, the outer wall of the water level pipe 1 is attached to the inner wall of the fixed net pipe 2 and can be pulled up and down, the outer sleeve comprises a closed pipe 3, a blowdown pipe 4 and a protection net pipe 5, the outer wall of the lower end of the blowdown pipe 4 is fixed on the inner wall of the outer sleeve opening of a circular rearing pond, the closed pipe 3 is arranged in the blowdown pipe 4, the outer wall of the closed pipe 3 is attached to the inner wall of the blowdown pipe 4 and can be pulled up and down, the protection net pipe 5 is arranged outside the blowdown pipe 4, the inner wall of the protection net pipe 5 is attached to the outer wall of the blowdown pipe 4 and can be pulled up and down, and particularly, the outermost protection net pipe 5 is put down in a normal running state, so that waste of feed can be prevented; when the pond is cleaned, the water inlet is closed, the protective net pipe is lifted upwards, the water body is stirred clockwise or anticlockwise, so that residual feed and excrement enter a space between the inner sleeve and the outer sleeve through a gap at the lower end of the sewage discharge pipe 4, the closed pipe 3 is put down when sewage is discharged, the water level pipe 1 is lifted to discharge the residual feed and the excrement, and the normal running state is recovered after the sewage is discharged.
