Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Embodiment
As Fig. 1, Fig. 2, shown in Figure 3, closed water-flowing type aquaculture net cage of the present invention, it comprises net cage body 10, net cage body 10 is made of inner mesh bag 20 and the outside seal bag 30 that is arranged on inner mesh bag 20 outsides, by outside seal bag 30 breeding water body is isolated with reservoir water body, externally sealed bag 30 be provided with can open or close change water window 40, net cage body 1 bottom tilts at an angle, make dirt can focus on the bottom, be provided with delivery port 50 in the bottom of net cage body 1, be connected with outlet pipe 51 on the delivery port 50, be provided with some hasps 11, be connected with a sinker 60 by hasp 11 in the lower edge of net cage body 10.
Outside seal bag 30 is used for waterproof, and inner mesh bag 20 is used for breed and prevents the fish escape, and has made things convenient for fish.
Be provided with the bandlet 70 that is used to connect buoyancy aid at the upper end-face edge place of net cage body 10, bandlet 70 usefulness waterproof materials are made, be used to connect buoyancy aid, can bear certain pulling force, when waterproof slide fastener 41 pull-ups, change water by water flooding regime, since inside and outside water-head, the bandlet 70 stressed (referring to Fig. 4) on the outside seal this moment bag 30; The bottom of changing water window 40 is connected with outside seal bag 30 one, and the both sides of changing water window 40 are connected with outside seal bag 30 by waterproof slide fastener 41, and the top of changing water window 40 is connected with outside seal bag 30 by a cingulum 42.
Change water window 40 and be opened in outside seal bag 30 both sides, waterproof slide fastener 41 is sewn in and changes on water window 40 the right and lefts and the outside seal bag 30,42 of cingulums are arranged on and change water window 40 tops, when cingulum 42 is untied, then change water window 40 when waterproof slide fastener 41 is left behind and open, change water with control thereby control the unlatching of changing water window 40.
Be provided with plurality of strengthening ribs 12 on the surface of net cage body 10, make the stressed reinforcement 12 that is evenly distributed on the net cage body 10, net cage body 10 stressing conditions are improved, strengthen the intensity of net cage body 10, prevent to draw bad.
As shown in Figure 5, delivery port 50 is connected with water out adapter 53 by flange 52, and outlet pipe 51 is connected to delivery port 50 by anchor ear 54 through water out adapter 53, is used for the draining blowdown, is connected to each other by bolt group 55 between delivery port 50 and the flange 52; When not changing water at ordinary times, the water side 56 on the outlet pipe 51 hangs on the buoyancy aid surfaces.
As Fig. 6, Fig. 7, shown in Figure 8, sinker 60 is for to be connected to each other the metal framework that constitutes by straight tube 61 and elbow 62, and straight tube 61 is provided with some tether rings 63, is connected with the hasp 11 of its lower edge of net cage body 10 by tether 13 by tether ring 63.
Each tether ring 63 is right against the hasp 11 of its lower edge of net cage body 10, prevents net cage body 10 deformation of bottom, and maximization stretching net cage body 10 makes cultured area reach maximum.
Closed water-flowing type aquaculture net cage of the present invention adopts sealing dry goods material to make the closed water-flowing type net cage with reference to the principle in the smart pond of continental rise cement, extracts the depths, and lower layer of water in the reservoir of water temperature, water stabilization is carried out flowing water and cultured; Have certain disease prevention and epidemic prevention function, when breed place reservoir water quality is good, waterproof slide fastener 41 is left behind, directly by changing water window 40 exchange breeding water bodies; When reservoir water quality was very poor, perhaps a lot of microorganisms in the water perhaps disease period occurred frequently, can be pulled on waterproof slide fastener 41, extracted qualified water by pump and injected net cage control water body quality and prevent disease.Finally reach the purpose of resources conservation, environmental friendliness, production safety.
Closed water-flowing type aquaculture net cage of the present invention is a kind of highly significant the new technology of China's eel industry to the industry form upgrading of resources conservation, environmental friendliness, production safety.This aquaculture model be with technology such as equipment technology, water purification technology, construction journey integrate, assembling and integrated, thereby reach healthy, grow fast and improve unit of water body output and quality to greatest extent, and do not produce internal and external environment pollutes, consume water resources not substantially, a kind of healthy aquaculture new model of not taking up an area of.This mode of production that consumes with the technology alternate resources meets the strategic decision that country changes the growth pattern development modernization agricultural of agriculture poor efficiency, high consumption, might become replenishing or substitute technology of China's aquaculture model.
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent thereof.
