Bottom-absorbing drainage gate in a pond culture system and using method thereof

Abstract

The invention discloses a bottom suction type emptying gate in a pond culture system and a using method, and belongs to the field of aquaculture facilities. The bottom suction type emptying gate comprises a main gate, a culture biology anti-escape gate, a fresh water drainage and bottom suction integrated gate and a drainage and pollution suction channel. The main gate, the culture biology anti-escape gate and the fresh water drainage and bottom suction integrated gate are sequentially arranged from outside to inside. The drainage and pollution suction channel is located on the inner side of a pond at the bottom of the gate and comprises a drainage and pollution suction channel upper channel, a drainage and pollution suction channel middle channel and a drainage and pollution suction channel lower channel. The inner side is the pond side. The bottom suction type emptying gate has the advantages that water exchange efficiency is high, the pollution suction capacity is high, and energy is saved; the problems that bottom-layer water rich in organic matter is difficult to drain out and benthic animals slowly grow and are prone to being sick in existing pond culture are solved, meanwhile, water exchange efficiency can be improved, pond water can be completely drained out of the pond, the water exchange quantity is reduced, and the culture cost is saved.

Description

Technical field: [0001] The invention belongs to the field of marine aquaculture, and in particular relates to a bottom-suction drainage gate in a pond aquaculture system and a method for using the same. Background technique: [0002] Pond aquaculture is the earliest aquaculture model in the history of our country. So far, this aquaculture model has been in a dominant position. According to statistics, the national pond aquaculture area accounts for about 35% of the total aquaculture area, and its output accounts for about 65% of the total output. above. With the development of aquaculture, the construction technology and aquaculture technology of aquaculture ponds have been continuously improved, and the production of pond aquaculture has also increased significantly. Among them, the design and construction of the gate as a channel for pond water exchange is one of the core processes of pond construction. [0003] Traditional gates generally include water retaining gates, ...

AI Technical Summary

Problems solved by technology

The invention has the characteristics of high water exchange efficiency, strong pollution absorption, and energy saving, and solves the problems of difficult drainage of bottom water rich in organic matter in existing pond culture, slow growth speed of benthic cultured animals, and susceptibility to disease; and, the invention It can improve the efficiency of water exchange, facilitate the drainage of pond water, reduce the amount of water exchange, and save the cost of breeding
