Embodiment

[0021] Example: refer to Figure 1 to Figure 3, a one-way self-power supply cage, including a rectangular floating tube 1 located at the top of the cage, wherein: below the floating tube 1 is connected a cylindrical cage 3 whose axis is a horizontal direction; one end of the cylindrical cage 3 has a ring-shaped reinforcement truss 11, and the other side of the reinforced truss 11 is connected with a diverter 2 with a conical steel pipe truss structure; the bottom of the cylindrical cage 3 is provided with an 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 that can monitor the surface flow velocity. The application of the conical diverter 2 has better stability for water body fluctuations than the prior art, so it can effectively achieve the instantaneous tension extreme value of the mooring rope system, effectively reduce the risk of anchoring, an...

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 offshore cage culture equipment, in particular to a one-way self-power supply 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 aquaculture density of shallow water cages in some coastal areas of China is relatively high, resulting in poor water flow and severe hypoxia in the aquaculture water. The overload phenomenon is serious. This farming method not only pollutes the water quality of the sea area, 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 cage culture from the inner bay and offshore to the sea or deep sea. In many countries in the world, after years of technical research, deep-water cage culture has become a leading i...
