Novel fish tank capable of automatically feeding by utilizing tide

Abstract

The invention belongs to the field of novel renewable energy technologies and aquaculture devices and particularly relates to a novel fish tank capable of automatically feeding by utilizing tide. The novel fish tank comprises a water storage room, a connecting pipe, a fish breeding room, an anchor chain, a piston, an upper-layer feed bin, a one-way valve and a lower-layer feed bin. The novel fish tank is characterized in that the water storage room is positioned at the upper part, the fish breeding room is positioned at the lower part, and both the water storage room and the fish breeding room are communicated with each other through the connecting pipe; four corers at the lower part of the fish breeding room are fixed at the sea bottom through an anchor chain connecting grip anchor. The novel fish tank has the benefits that fishes in the fish tank can be automatically fed by the utilization of sea water level change and in combination with high and low water head difference in the tidal process; the novel fish tank has the advantages of higher reliability and easy manufacture, mounting and movement.

Description

technical field [0001] The invention belongs to the field of novel renewable energy technology and aquaculture equipment, in particular to a novel fishing box which utilizes tidal energy for automatic feeding. Background technique [0002] Scientific farming of fish is very important in increasing fish production. In recent years, people have adopted multi-species breeding methods, widely used aerators to increase oxygen, increased stocking density and other methods, tapped the production potential of water bodies, and significantly increased production. During the same period, ocean energy, one of the main renewable energy sources, has also made great progress, and the application technology of ocean energy has become more and more mature, showing a bright prospect for mankind to make full use of ocean energy in the 21st century. Therefore, combining the two fields of ocean energy utilization and fish farming has great significance for their respective development, and it ...
