AI Technical Summary

Technical Problem

The hot water pipe of the existing shrimp seedling cultivation pool is set at the bottom of the seedling cultivation pool, and the water body cannot be heated comprehensively and evenly, resulting in differences in water temperatures at different locations in the seedling cultivation pool, affecting the breeding effect and survival rate of shrimp seedlings.

Method used

A shrimp seedling cultivation pool was designed, and a stirring unit was set up at the bottom of the seedling pond using multiple hot water conveying pipes, including a waterproof protection box, a stirring motor and a stirring blade. Through the disturbance of the stirring blades, the water at the bottom of the seedling pond and the water at the upper part were mixed evenly.

Benefits of technology

Through the use of the stirring unit, the difference in water temperatures in different locations in the seedling pond is reduced, the survival rate and yield of shrimp seedlings are improved, and the mortality rate of shrimp seedlings is reduced.

Abstract

The utility model discloses a shrimp seed nursery pond which comprises a nursery pond body, a hot water conveying pipe and a stirring unit. A seedling raising frame is arranged in the seedling raising pond, and a plurality of mounting grooves are formed in the bottom end of the seedling raising pond at intervals; the hot water conveying pipes are correspondingly arranged in the mounting grooves respectively; the number of the stirring units is two, the two stirring units are fixedly installed at the bottom end of the nursery pond in a mutually staggered mode, each stirring unit comprises a waterproof protection box, a stirring motor and stirring blades, each waterproof protection box is fixedly connected between every two adjacent installation grooves, the stirring motors are installed in the waterproof protection boxes, and the stirring blades are arranged in the waterproof protection boxes. An output shaft of the stirring motor vertically penetrates through the upper end of the waterproof protection box, a mounting block is connected to the top end of the output shaft, and the stirring blades are symmetrically connected to the two sides of the mounting block respectively. According to the utility model, the difference of water temperatures at different positions in the nursery pond can be reduced, so that the death rate of shrimp seeds can be reduced, and the yield and survival rate of the shrimp seeds can be improved.
