Description
Technical field
The utility model relates to a kind of net cage, especially relates to a kind of aeration type fish culture net cage.
Background technology
Along with the development of culture fishery, cage culture is more and more universal, fish culture in net pen close for pond spermiation is supported Technology application to obtain the intensive breeding way of a kind of height of high yield to the superior larger water surface of environmental condition, can save excavation fishpond need soil, labour, produce effects after investment fast.Fish culture in net pen can make full use of that water body and erbium material are raised together with to carry out, dense stocking, has that breeding cycle is short, convenient management, has maneuverability, easy and simple to handle, survival rate advantages of higher, can reach object of achieving higher output.
But because the fish culture density in net cage is higher, the fish anoxic caused in net cage is easy in breeding process, therefore need to carry out oxygenation to the water body in net cage, and the most frequently used mode of at present carrying out oxygenation to water body in net cage adopts to be placed in water-bed aerator directly to blasting air in net cage, the bubble that aerator produces is very large, can emerge at short notice, make oxygen can not be fully soluble in water, and the air pocket that oxygenation produces can make fish get a fright, improve the stress reaction of fish, affect normally ingesting and growing of fish, in addition, aerator sinks to the bottom, be inconvenient to carry, use very flexible.
Utility model content
The utility model is that the fish culture net cage existence in order to solve prior art easily causes water hypoxia, affect the problem of fish culture, provide a kind of structure simple, use flexibility good, maintenance is convenient, can carry out oxygenation and the good aeration type fish culture net cage of oxygenation effect to the water body in net cage.
To achieve these goals, the utility model is by the following technical solutions:
A kind of aeration type fish culture net cage, comprise net cage frame, be fixed on the etting below net cage frame, described net cage frame is provided with the first ball float, heavy piece is provided with bottom described etting, described aeration type fish culture net cage also comprises kickboard, suction pump, injector and conduit, described kickboard is positioned at net cage frame outside, the second ball float is provided with bottom kickboard, also holder is provided with bottom kickboard, described suction pump is fixed on holder, the delivery port of suction pump is connected with the import of injector, air intake pipe on injector passes kickboard and protrudes from above kickboard, the outlet of injector is connected with conduit, the port of export of described conduit is positioned at etting and the port of export is provided with shower nozzle, described shower nozzle is fixed in etting by the lanyard be connected with net cage frame.In the utility model, kickboard is fixed by rope, net cage can suck containing the water that oxygen is abundant outward by suction pump, export from delivery port, after the water exported and the air be drawn in injector from the air intake pipe injector carry out mixing wastewater with air, bottom the net cage being incorporated into anoxic through conduit and nozzle, carry out high efficiency oxygenation; Kickboard is positioned at net cage frame outside, to make full use of the space of net cage, can avoid interfering with net cage simultaneously and cause net cage damaged, also easy access.
As preferably, described holder is " L " shape structure be made up of transverse slat and riser, and described suction pump is fixed on transverse slat.
As preferably, the turning point longitudinal separation in described etting is provided with some slip rings, is provided with stay cord in described slip ring, and the upper end of described stay cord is connected with net cage frame, and the lower end of described stay cord is connected with heavy piece.Slip ring plays spacing effect, avoids stay cord to rock in etting, plays the effect of guiding when receiving net simultaneously, is conducive to folding and unfolding etting clothes.
As preferably, described shower nozzle is the cylindrical structure of open top, and the opening of shower nozzle is connected with the port of export of conduit, and described nozzle surface is provided with spray orifice.Nozzle surface is provided with spray orifice, can produce a large amount of minute bubbles, and the minute bubbles of generation can not improve the stress reaction of fish in net cage, and can be detained for a long time in water body, and oxygen is fully dissolved in water body.
As preferably, the diameter of described spray orifice is 0.5 ~ 1mm.
Therefore, the beneficial effects of the utility model are: structure is simple, use flexibility good, can carry out oxygenation and oxygenation effect is good to the water body in net cage, can not improve the stress reaction of fish in net cage.
