Aquaculture net cage

Abstract

The invention discloses an aquaculture net cage. The aquaculture net cage comprises a cage body frame, wherein a cage body comprises a bottom plate, two long-edge side plates and a short-edge side plate, and the short-edge side plate comprises a fixed plate and a movable plate; each long-edge side plate comprises a plurality of baffle plates and telescopic assemblies used for connecting every twoadjacent baffle plates; each telescopic assembly comprises a first hinge strip and a second hinge strip; waist-shaped holes are formed in the lower parts of the baffle plates, and first sliders sliding in the waist-shaped holes are arranged on the baffle plates; one end of each first hinge strip is hinged with the upper part of the corresponding baffle plate, and the other end is hinged with the first slider on the adjacent baffle plate; one end of each second hinge strip is hinged with the upper part of the adjacent baffle plate, and the other end is hinged with the first slider on the baffleplate; each first hinge strip and the second hinge strip on the adjacent telescopic assembly are coaxially hinged onto the same first slider; when the movable plate moves in the direction opposite tothe fixed plate, the adjacent baffle plates are conflicted with each other to be separated from each other, and therefore, the culture space of the cage body becomes larger.

Description

technical field [0001] The invention relates to an aquaculture device, more specifically to an aquaculture net cage. Background technique [0002] At present, aquaculture technology is widely promoted in most parts of our country. Among them, cage fish farming is a highly intensive farming method that applies the pond intensive intensive farming technology to large water surfaces with superior environmental conditions to obtain high yields. It has the advantages of short feeding cycle, convenient management, flexible maneuvering, and easy operation. . In the process of cage culture, since the internal space of the cage is fixed, as the cultured fish gradually grow up, the original space of the cage is no longer suitable for continuing to breed this type of fish. This kind of farmed fish is salvaged and put into another cage to continue to breed; during the whole breeding process, the farmer needs to salvage and put in several times, which is very time-consuming and laborio...

Problems solved by technology

In the process of cage culture, since the internal space of the cage is fixed, as the cultured fish gradually grow up, the original space of the cage is no longer suitable for continuing to breed this type of fish. This kind of farmed fish is salvaged and put into another cage to continue to breed; during the whole breeding process, the farmer needs to salvage and put in several times, which is very time-consuming and laborious; Fish are easy to die, which greatly increases the cost of breeding and causes certain economic losses to farmers
