Self-cleaning attachment device for factory-like circulating aquaculture of sea cucumbers

Abstract

The invention relates to a self-cleaning attachment device for factory-like circulating aquaculture of sea cucumbers and belongs to the field of aquaculture equipment. The device is composed of a rotatable attachment plate assembly and a fixed support assembly. The rotatable attachment plate assembly comprises a corrugated plate, a shaft tube and a spacing tube. The corrugated plate is circular, a through hole is formed in the center of the corrugated plate, radial corrugated ribs are arranged from the through hole to the circumference, and a clamping groove is formed in the edge of the through hole. A fixed support comprises two supporting plates, a pool bottom flushing pipe and a corrugated plate flushing pipe. The device not only provides an attachment habitat for sea cucumbers, but also can automatically remove dirt on an attachment plate and the bottom of a culture pond.

Description

technical field [0001] The invention belongs to the field of aquaculture equipment, and in particular relates to a sea cucumber attachment device with automatic cleaning function for sea cucumber industrialized circulating aquaculture. Background technique [0002] Sea cucumber (Sea cucumber), also known as japonicus, sea rat, and sea cucumber, belongs to the phylum Echinodermata, the class Holothuria, and the genus Holothurian. It is a typical high-protein, low-fat food. [0003] The huge market demand has promoted the development of the sea cucumber aquaculture industry. At present, it has formed a huge industry mainly based on pond aquaculture and near-shore bottom sowing aquaculture, supplemented by land-based industrial aquaculture and sea cage aquaculture, with an annual output value of more than 20 billion Yuan. Since sea cucumbers are narrow-temperature and narrow-saline animals, their optimum growth temperature is 10-17°C and the optimum growth salinity is 28-35°C....

AI Technical Summary

Problems solved by technology

However, sea cucumber indoor factory culture needs to be fed a large amount of algae powder and sea mud daily. When sea cucumber eats, it uses tube feet to crawl on the wall of the pool and the attachments placed in the pool to increase the attachment area of ​​sea cucumber, and scrapes it off with mouthparts. The algae powder and sea mud that fall on the wall of the pool or the surface of the attachment, the feces discharged adhere to the surface of the attachment or fall to the bottom of the pool. Sea cucumber feces contain more than 90% of sediment, which is extremely difficult to be washed away by water. During the breeding process , the sea cucumber must be removed every 5-7 days, and the cleaning of the pool wall and the attachments in the pool can be realized through this frequent "inverting the pond". cleaning problem
