Description

Tank type float/sink deep water net cage

[technical field]

The present invention relates to a kind of deep water mesh cage, especially a kind of tank type float/sink deep water net cage of wind wave resistance.

[background technology]

Fish culture in net pen is the topmost mode of mariculture, has very vast potential for future development.The tradition cage structure is simple, and framework is mainly with materials processings such as planks, the wind wave resistance poor performance, and small scale, service life is short, and can only influence the development of mariculture industry in inner bay and offshore setting.Develop novel net cage, the development deep water mesh cage is breeded fish, and utilizes new and high technology that traditional net cage is transformed, and has become the matter of great urgency.Oceanography Institute Of Zhejiang has born project, the Zhejiang Province's science and technology Xinghai County's key project " large-scale deep-water netted case resisting wind and wave and efficient cultural technique research " of listing country " 863 " plan in, (seeing report in " Chinese ocean newspaper " on March 29th, 2002), the characteristics that project team is big according to deep water sea area wind, wave is high, stream is anxious, the appropriate design structure, elevation (over-and-under) type underframe, multi-level and air bag elevated live cage have been succeeded in developing in innovation, this deep water mesh cage performance indications reach 12 grades of wind resistance power, anti-wave is high 5 meters, anti-current speed 1 meter per second.Satisfy the needs of China's mariculture.But in actual applications, also have some defectives: (1) adopts special-purpose HDPE material to do skeleton cost cost height, is difficult to large tracts of land and promotes; (2) sedimentation imbalance, easy run-off the straight when net cage sinks is run helter-skelter the shoal of fish; (3) adopt the tubular structure inflatable drainage, need to give inflation, use inconvenient with the ship of band air compressor; (4) the stressed sectional area that impacted by seawater is big; (5) support is unfavorable for that the people walks in the above, in the above inconvenient operation and safety.

[summary of the invention]

Purpose of the present invention designs a kind of tank type float/sink deep water net cage exactly, and its cost is low, and is durable in use, and structural safety is reliable, and the sudden and violent performance of wind resistance is good, and Compressed Gas is provided in steadily landing for oneself during sink-float, need not special-purpose inflatable dinghy, and the people is easy to operate on net cage, safety.

The present invention is achieved like this, it comprises inner ring, the outer ring, collar, the net bottom circle, support, air accumulator, jar drifts along, high-pressure hose, low-pressure hose, balance pipe, intake valve, air bleeding valve, coupling cock, safety valve, cover net, barrel-shaped net, with several supports with inner ring, the outer ring, collar is fixed, constitute the upper frame of net cage, be distributed with several air accumulators and the jar that drifts along in around upper frame, all air accumulators all communicate with high-voltage tube, high-voltage tube connects high-pressure hose and intake valve and coupling cock, the jar that drifts along all is connected with tracheae, tracheae one end connects low-pressure hose and air bleeding valve and coupling cock, the other end connects the jar that drifts along, drifting along connects a balance pipe below the jar, connects safety valve below the balance pipe.In order to make the people easy to operate on net cage, support is the L type, and inside and outside circle is fixed in the support bottom, and top is tracheae and collar fixedly.Inner ring, outer ring, collar, net bottom circle all adopt Composite steel-plastic pipe do or, (at the appearance coating plastics of steel pipe) had so both guaranteed the intensity of steel pipe to have the anticorrosion advantage of plastics again, significantly reduced the stressed sectional area of net cage when impacted by seawater.

The present invention has following advantage: (1) provides air accumulator for oneself and the jar that drifts along, and inflatable drainage when rising, need not to inflate with the ship of band air compressor automatically; (2) all drift along during jar inflatable drainage stressed evenly, net cage can not tilt during sedimentation, causes the shoal of fish to run helter-skelter; (3) inner ring of net cage, outer ring, collar, net bottom circle all adopt Composite steel-plastic pipe, and the sectional area that impacted by seawater reduces, and improves the performance of wind wave resistance, anti-high current greatly; (4) adopt L type support fixed network box-frame, the people walks conveniently in the above, handling safety.

[embodiment]

As Fig. 1, Fig. 2, shown in Figure 3, the present invention includes inner ring (21), outer ring (20), collar (23), net bottom circle (18), support (22), air accumulator (9), drift along jar (13), high-pressure hose (7), low-pressure hose (6), balance flexible pipe (14), intake valve (2), air bleeding valve (1), coupling cock (5), safety valve (15), cover net (12), barrel-shaped net (17), with several supports (22) with inner ring (21), outer ring (20), collar (23) is fixing, constitute the upper frame of net cage, be distributed with several air accumulators (9) in around upper frame and drift along jar (13), all air accumulators all communicate with high-voltage tube (10), high-voltage tube connects high-pressure hose (7) and intake valve (2) and coupling cock (5), compressed air can enter in the net cage air accumulator all around simultaneously, people can inject compressed air in the air accumulator in advance by intake valve and store for future use, have manometer (8) controlled air pressure on the high-voltage tube, the jar (13) that drifts along all is connected with tracheae, tracheae (11) connects low-pressure hose (6) and air bleeding valve (1) and coupling cock (5), the other end connects the jar that drifts along, drift along and connect a balance pipe (14) below the jar, connect safety valve (15) below the balance pipe (14), when net cage floats on the surface at ordinary times, the jar that drifts along is interior to be air, allow net cage sink, as long as open air bleeding valve, water injects the jar that drifts along from safety valve (15), the net cage balance is sunk, want to allow net cage rise, as long as open coupling cock (5), gas in the air accumulator enters the jar that respectively drifts along equably by low-pressure hose, jar interior water that drifts along is discharged, and net cage rises evenly.On intake valve and air bleeding valve, be connected buoy (3), make valve always be exposed on the water surface, on the net cage with rope several ball floats (4) that play, several sinkers (19) play on net bottom circle (18), be connected with setting rope (16) between upper frame and the net bottom circle, use barrel-shaped net (17) to wrap all around, the top of net cage covers with cover net (12).Support (22) is made with the HDPE material, inside and outside circle is fixed in its underpart, top is tracheae and collar fixedly, the people can walk around net cage, handling safety, convenience, stressed sectional area when impacted by seawater and reducing production costs in order to reduce net cage, inner ring, outer ring, collar, net bottom circle all adopt Composite steel-plastic pipe to make, (at the appearance coating plastics of steel pipe), the intensity and the corrosion resistance of steel pipe had so both been guaranteed, significantly reduce the stressed sectional area of net cage when impacted by seawater again, improve its wind wave resistance performance greatly.
