Embodiment

[0021] Example: refer to Figure 1 to Figure 3, a one-way self-powered net cage, including a rectangular floating tube 1 located on the top of the net cage, wherein: a cylindrical net cage 3 with a horizontal axis is connected below the floating tube 1; one end of the cylindrical net cage 3 has a ring-shaped reinforced truss 11, and the other side of this reinforcement truss 11 is connected with the diverter 2 that has conical steel tube truss structure; The bottom of cylindrical cage 3 is provided with a HDPE immersed pipe 31 along the direction parallel to the axis; HDPE immersed pipe 31 is filled with iron sand; the shunt 2 is also connected with a floating power supply module 5 capable of monitoring the surface velocity. The application of the conical diverter 2 is more stable to the fluctuation of the water body than the prior art, so it can achieve the extreme value of the instantaneous tension of the mooring rope system, effectively reducing the risk of anchoring, there...

Abstract

The invention discloses a one-way self-powered net box. The one-way self-powered net box comprises a rectangular floating pipe which is arranged at the top of the net box; a cylindrical net box with an axis being in the horizontal direction is connected below the floating pipe; one end of the cylindrical net box is provided with an annular reinforcing truss; the other side of the reinforcing truss is connected with a flow divider with a conical steel pipe truss structure; the bottom of the cylindrical net box is provided with a HDPE immersed tube along the direction which is parallel to the axis; the HDPE immersed tube is full of iron sand; the flow divider is connected with a floating power supply module which can monitor the surface flowing speed. Application of the conical flow divider is good in water body fluctuation stability compared with the prior art and accordingly an instant tensile force extreme value of an anchor rope system becomes effective, risks of dragging of anchor are effectively reduced, a construction requirement for an anchoring device is reduced, and the one-way self-powered net box has the advantages of being stable in structure, protruding in flow resistance, good in stability, low in cost, low in construction process requirement, high in safety, energy saving and capable of monitoring the net cage surface flowing speed.

Description

technical field [0001] The invention relates to an off-shore cage culture equipment, in particular to a one-way self-powered cage. Background technique [0002] As a traditional farming method, shallow water cage culture is mainly concentrated in semi-enclosed bays. Affected by economic interests, the density of shallow-water cage culture in some coastal areas of China is relatively high, resulting in poor water flow and severe hypoxia in some cultured water bodies. In addition, residual bait and fish excrement cannot be quickly transported out with the water body, resulting in the environmental capacity of the cultured water body. The overload phenomenon is serious. This farming method not only pollutes the water quality of sea areas, but also affects the quality of farmed fish, and has also become one of the main factors that induce coastal red tides. Therefore, it is the only way for the sustainable development of cage culture to gradually transfer the cage culture from...
