Aquaculture box capable of periodically changing water and increasing oxygen

Abstract

The invention discloses an aquaculture box capable of periodically changing water and increasing oxygen in the field of aquaculture. The aquaculture box mainly comprises an aquaculture box body, a water inlet is formed in a cover plate of the aquaculture box body, and a water outlet is formed in a bottom plate of the aquaculture box body; balloons are installed on the breeding box body, a sliding plate is arranged below the balloons, the sliding plate slides in the vertical direction, and a wedge face a is arranged at the bottom end of the sliding plate. A first switch plate used for opening and closing the water outlet is slidably mounted on a bottom plate of the breeding box body, and a wedge surface b is formed in one end, close to the sliding plate, of the first switch plate and slidably mounted on the wedge surface a; the bottom end of the sliding plate is connected with a bottom plate of the breeding box body through a first compression spring, and the sliding plate is hinged to the first switch plate through a connecting rod. According to the device, water can be automatically drained in the breeding box, manual operation is avoided, the water drainage opportunity can be automatically judged according to the oxygen concentration in the breeding box, water is automatically drained when the set concentration is reached, the labor cost is saved, and waste of water resources is avoided.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to an aquaculture box with periodic water exchange and oxygenation. Background technique [0002] Aquaculture is the productive activity of multiplying, cultivating and harvesting aquatic plants and animals under human control. Aquaculture has extensive culture, intensive culture and high-density intensive culture. Extensive culture is to put seedlings in small and medium-sized natural waters, and grow aquatic products entirely by natural bait, such as fish culture in lakes and reservoirs and shellfish culture in shallow seas; Aquatic products, such as pond fish culture, cage fish culture and fence culture, etc.; high-density intensive culture adopts the methods of running water, temperature control, oxygenation and feeding high-quality bait, etc., and high-density culture is carried out in culture boxes to obtain high yields. Such as running water high-density fish, shrimp and so on. ...

AI Technical Summary

Problems solved by technology

The existing high-density intensive cultivation uses primary water. When there are too many impurities in the water, it is necessary to manually discharge water, change water and increase oxygen, which is extremely inconvenient.

And at present, it is necessary to manually judge the timing of changing water and increasi
