A hdpe self-tensioning flat-bottom lifting type current-resistant cage device

Abstract

A HDPE self-tensioning flat-bottom lifting type flow-resistant net cage system and a control method relate to the field of seawater net cage culture facilities. It is a spherical net cage main frame (1) constructed of HDPE pipes, high-strength fishing ropes (2), center gravity pendulum self-balancing device (3), netting (4), and HDPE pipe row inflation port (5), composed of high-strength exhaust and inflation hose (6), and HDPE inlet and outlet pipes (7); the design principle is reasonable, the structure is simple and easy to implement, the cost is low, easy to operate, the cage structure system has good flow resistance, and the underwater The breeding platform is large, can be multi-layered and three-dimensional, saves space, improves efficiency, can sink into the bottom of the water or stay in different water layers, is flexible and maneuverable, can avoid the attack of typhoons and red tides, can breed different types of fish, and has a wide range of applications.

Description

Technical field: [0001] The present invention involves the field of seawater cage breeding facilities, especially the HDPE from the tension of the upper and lower -dating cage system and control methods of HDPE. Background technique: [0002] With the rapid development of deep water anti -wind waves and supporting technologies, the core lifting technology of deep -water lifting cages must not only have the function of resisting strong storm attacks and avoiding red tide disasters, but also uses it to sink into the bottom of the sea.The breeding of catfish creates a suitable ecological environment near the sea floor; therefore, the research focus of the deep -water cage has gradually improved the direction of the dedicated cage of different varieties of fish that is suitable for different varieties of fish.develop. [0003] In recent years, the breeding boom of dental fish has emerged along the coast of the northern part of my country, and it has been fully developed by cage bree...

Problems solved by technology

However, the wooden traditional floating raft small net cage has poor wind and wave resistance. The steel structure bottom frame should not be too large due to weight and deformation restrictions, and the net cage cannot be lifted. When encountering strong wind and waves, it is easy to cause damage to the net cage and run fish , causing great economic losses to farmers, so it is inevitable to develop a lift-type anti-wind and wave cage with a large net bottom habitat platform area and suitable for the breeding environment of flounder and flounder.
