Description
[technical field]
The present invention relates to a kind of deep water mesh cage, the tank type float/sink deep water net cage of especially a kind of wind wave resistance and red tide.
[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 pipe 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 all adopt clad steel to mould and make, and have so both guaranteed to have the anticorrosion advantage again by the intensity height, and the stressed sectional area when making net cage impacted by seawater is little.
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 all adopt clad steel to mould to make, and the sectional area that impacted by seawater is little, and the performance of wind wave resistance, anti-high current is good; (4) adopt L type support fixed network box-frame, the people walks conveniently in the above, handling safety.
