Description

Technical Field

[0001] The utility model relates to the field of connecting equipment, in particular to a cage frame for oyster cultivation. Background Art

[0002] During the deep-sea aquaculture of oysters, due to the strong winds and waves, the aquaculture mainly adopts a frame (floating raft) for hanging. The frame is mainly composed of buoys (floating tubes), walkway boards and wood or round tubes, which are connected to each other by bundling. However, the wood or round tubes that are perpendicular to each other are all cylindrical, with a small contact area, poor stability, and cumbersome fixation. CN212697236U discloses a new type of wind and wave resistant oyster raft connecting auxiliary parts, which is suitable for artificial aquaculture floating rafts composed of cylindrical tubes arranged horizontally and vertically. It is composed of two mutually perpendicular arc-shaped thin plates; the connecting surface of the arc-shaped thin plates is a rectangular surface; the two mutually perpendicular arc-shaped thin plates are integrally formed. In order to ensure the surface contact between the connecting auxiliary parts and the cylindrical tubes, the direct contact area of ​​the two mutually perpendicular arc-shaped thin plates is not large, which can easily cause damage to the connecting auxiliary parts when the winds and waves are strong. After the connecting auxiliary parts are damaged, it is necessary to replace the auxiliary parts for both cylindrical tubes at the same time, which can easily cause waste of resources. Compared with cylindrical tubes, square tubes have a larger contact area, but the connection and fixation between square tubes also have problems such as poor stability and easy dislocation.

[0003] In addition, during the oyster farming process, the cages are directly hung on the buoy. When the wind and waves are strong, the hanging ropes are easily tangled, causing oysters to gather, resulting in increased oyster farming density in some locations, large nutritional loss, affecting oyster growth, and causing economic losses.
