Embodiment
Below in conjunction with specific embodiments and the drawings, set forth the present invention further.
As Figure 1-5, a kind of high density environment-protecting cultivation net cage, comprises the net cage body 1 of the rectangle of opening upwards.
The left and right sidewall 11,12 of described net cage body 1 offers mesh, the right side of net cage body 1 is provided with bubble generator 2 and bubble reflecting plate 3, one end of bubble generator 2 is connected with right side wall 12 bottom vertical of net cage body 1, one end of bubble reflecting plate 3 be connected with right side wall 12 top of net cage body 1, the other end of bubble reflecting plate 3 and the other end of bubble generator 2.
The outer horizontal symmetrical of forward and backward sidewall 13,14 of described net cage body 1 is provided with the floating drum 4 that sidewall 13,14 forward and backward with this is connected.
The left end of the bottom of described net cage body 1 has sewage draining exit 16, and sewage draining exit 16 is connected with the blow-off pipe 5 outside net cage body 1, is provided with air-lift device in blow-off pipe 5.
Wherein, the bottom of net cage body 1 is preferably the downward taper of the vertex of a cone, and the vertex of a cone is positioned at the left end of net cage body 1, and the vertex of a cone has sewage draining exit 16; The bottom of this structure is conducive to residual bait ight soil and piles up toward sewage draining exit 16 place.
The plastic deeping of the left and right side of the rectangular frame that net cage body 1 is made up of stainless steel square tube, the covering bottom of rectangular frame and the PVC waterproof cloth of forward and backward side and covering rectangular frame forms.
Bubble generator 2 is made up of the water pipe some tube walls having symmetrical through hole, and water pipe is bent into rectangular configuration, is provided with some water pipes being parallel to the minor face of rectangular configuration in rectangular configuration.
Net cage body 1 is of a size of long 4000mm, wide 1500mm and high 800mm.
The left and right two ends of floating drum 4 flush with the left and right sidewall 11,12 of net cage body 1 respectively, and floating drum 4 is positioned at 1/2nd At The Heights of net cage body 1; The floatage energy of floating drum 4 makes the opening edge of net cage body 1 along being advisable a little more than the water surface.
Blow-off pipe 5 is L-shaped, and one end of blow-off pipe 5 connects sewage draining exit 16, the other end of blow-off pipe 5 and the neat height of floating drum 4.
High density environment-protecting cultivation net cage of the present invention need coordinate turbofan together to use, generally net cage is placed on by riverain lake or river, blow-off pipe connects extension pipe and passes in the dirty pond of collection, turbofan is placed on the bank, the air outlet of turbofan connects air-lift device and blast pipe simultaneously, blast pipe stretches in water, its outlet is upwards just to bubble generator 2, between air-lift device and blast pipe, conversion valve is housed, the air outlet of turbofan is only communicated at one time or blast pipe communicates with air-lift device, generally exchange and blowdown at the water body carried out in a net cage in 1-3 hour of throwing something and feeding to cultured fishes.
When water body exchanges, regulate conversion valve that the air outlet of turbofan is communicated with blast pipe, by the exchange times regulating the air quantity of turbofan to control water body in net cage.The gas of discharging in blast pipe produces the even minute bubbles of rising after bubble generator 2, this bubble produces current again after bubble reflecting plate 3, the plastic deeping of water outside net cage body 1 on the right side of net cage body 1 is flowed into, the plastic deeping of water in net cage body 1 on the left of net cage body 1 is flowed out, reach the object of water body exchange with this, bubble also plays the effect of oxygenation; The conical lower portion of recycling net cage body 1 and the flow direction of water, make the residual bait ight soil in net cage concentrate on sewage draining exit 16 place.
During blowdown, regulate conversion valve that the air outlet of turbofan is communicated with air-lift device, utilize air-lift device together to be discharged through blow-off pipe with current by the residual bait ight soil concentrating on sewage draining exit 16 place, final inflow in the dirty pond of collection focuses on.
High density environment-protecting cultivation net cage of the present invention is while utilizing the water body in the overall situation such as lake, river, also the cleannes of the water body in this overall situation are maintained, avoid residual bait ight soil to the pollution of water body, namely achieve the object of intensive cultivation, do not destroy ecotope again.
