The aquaculture method is extensive, with problems such as unreasonable aquaculture layout, excessive aquaculture density, and low aquaculture quality. The limited coastal marine resources can no longer bear the pressure of the continuous growth of the total amount of aquatic products. my country has vast deep-sea aquaculture sea resources. The state encourages the development of deep-sea aquaculture and the establishment of marine granaries. Deep-sea aquaculture cages are located in deep waters with open waters and smooth water flow, which can reduce the problems of slow fish growth and high disease incidence caused by poor water exchange and unstable water quality in ordinary cage aquaculture.

[0003] At present, large-scale farming at home and abroad mostly uses HDPE gravity cages, which have the characteristics of simple structure, low comprehensive cost, convenient maintenance, and the assembly of cages is not restricted by the site. According to the different farming scales and farming modes, the cages can be fixed by single port or in groups. The layout of the cages with single port is more dispersed, and the water exchange of the cages is more unobstructed. The cages fixed in groups can improve the farming efficiency and water utilization rate.

[0004] The southeastern coast is the main sea area for deep-sea aquaculture in my country, and my country is one of the countries most hit by typhoons in the world. Every summer, several typhoons land in the southeastern coastal provinces, causing significant economic losses to the southeastern coastal provinces, especially the losses of aquaculture facilities. The main structure of the HDPE cage is a high-molecular polyethylene material with limited structural strength. When a typhoon of level 14 or above comes, the HDPE cage is often difficult to escape. Therefore, it is necessary to design a new type of marine ranch net device to improve the cage's ability to survive in extreme weather. Utility Model Content

[0041] See also Figures 1 to 7 The utility model provides a novel marine ranch cage device, which is used to be set in the ocean for aquaculture, including several cage units 1 and multiple anchoring mechanisms 2. The cage unit 1 includes a steel main frame 11, a floating body 12, a net 13 and a counterweight 14. The steel main frame 11 has a accommodating space, and the floating body 12 is filled in the accommodating space. The steel main frame 11 and the floating body 12 float on the sea surface, and the net 13 is suspended on the steel main frame 11, and a breeding area is formed in the middle of the net 13. The counterweight 14 is connected to the lower side of the net 13; the anchoring mechanism 2 includes an anchor pile foundation 21 and a clamp 22. The anchor pile foundation 21 is inserted into the seabed land, and the clamp 22 is sleeved on the anchor pile foundation 21 through a connecting hole opened thereon, and is fixedly connected to the steel main frame 11 of the steel cage unit 1.

[0042] In the novel marine ranch cage device of the utility model, the steel main frame 11 of the cage unit 1 has good structural strength and plays a supporting role. It can support the upper end of the net 13 to keep it in a stable opening shape. The steel main frame 11 also provides an installation and accommodation space for the float 12. The float 12 makes the steel main frame 11 and the float 12 as a whole float, ensuring that the upper end of the net 13 exceeds or approaches the sea surface. The counterweight 14 is used to open the net and act as a counterweight to ensure that the net 13 maintains its shape under the action of the ocean current, so that a breeding area with a certain effective breeding water body is formed inside. The cage unit 1 maintains a stable position on the sea surface through the anchoring mechanism 2, and the clamp 22 can slide up and down along the anchor pile foundation 21, so that the cage unit 1 can smoothly rise and fall under the action of waves. Since the cage unit 1 adopts the method of combining the steel main frame 11 with the floating body 12, the structural strength is large while ensuring the floating ability. Compared with the existing HDPE cage, the structural strength is greatly improved, which can effectively resist extreme weather such as typhoons, improve the self-sustaining capacity of breeding equipment, maintain the effective water area of ​​the cage unit 1 under strong winds and waves, and ensure breeding safety. The pile foundation 21 and the hoop 22 are used for anchoring, and the pile foundation can reduce the occupation of the breeding water body, improve the utilization rate of the pasture water body, and is also conducive to the underwater dredging operation of the robot.

[0043] See also Figures 1 to 7 The present invention is further described below with a specific embodiment:
