Fish raft net cage prepared from steel material

Abstract

The invention discloses a fish raft net cage prepared from steel material. The fish raft net cage prepared from steel material comprises a net cage body, the net cage body is connected with a floating steel frame, the floating steel frame is composed of steel pipes in a connecting mode, wherein each steel pipe is 245 to 610 millimeters in diameter and 1 to 10 millimeters in wall thickness, the inside of each steel pipe is hollow, and the steel pipes are connected to form the floating steel frame with closed pipelines; bends of the floating steel frame are connected by elbows, the parts of the steel pipes to be connected without bends are connected through welding and fixing after cutting to form matched nicks, a steel pedal with 70 centimeters in width is welded above the steel frame, and a steel frame guardrail with 60 centimeters in height is welded on the pedal; a working platform is welded at one side of the steel frame through a triangular steel plate. According to the fish raft net cage prepared from steel material, the large-diameter steel pipes serve as the fish raft framework and also serve as a buoyancy device, the fish raft firmness and stability are obviously improved, and the safety of the poultry feeders is guaranteed through the steel frames at the two sides of the passage. Net cages can form a large net cage group through connecting; the fish raft net cage prepared from steel material facilitates work and management and increases the typhoon resistance ability.

Description

technical field [0001] The invention relates to a fishing raft cage made of steel, which belongs to the technical field of marine aquaculture. Background technique [0002] At present, the scale of cage culture in my country is very large, and most of them are concentrated in the southern coastal areas where typhoons often land, such as Guangdong, Guangxi and Hainan. For the aquaculture operators in these areas, the most urgent problem to be solved in cage culture is the poor stability of the cages and the problem that they are easily damaged when typhoons come. [0003] In the coastal waters, aquaculture operators often adopt fishing rafts for cage farming, and the raft structure is connected vertically and horizontally by wooden boards to form a collection of multiple rectangular square arrays in the vertical and horizontal directions. A plurality of plastic buoys or foam buoys are tied below the plank to support the plank, and the entire square array of net cages floats ...
