Description

A anti-ocean current net cage

Technical field

A anti-ocean current net cage, is a kind of extra large suitable for ocean current relatively urgency and the novel net cage in the open sea area without shield, category Foreign engineering field.

Background technology

Cage culture is the pith of marine economy, and the gravity type HDPE net cages introduced at present by Norway develop rapidly, In the yellow Bohai Sea, the East Sea, the South Sea, has a large amount of raisers to use, which facts have proved not Anti-Typhoon outer, and anti-ocean current ability is also very Difference.It may deform during current speed only up to 0.257m/s, support 80% net cage of loss according to observations when flow velocity reaches 1m/s Volume is grown, therefore, from south to northern each province's provincial standard with regulation to HDPE net cages, flow velocity cannot be used in by, which all clearly limiting, is more than 1m/s sea areas, so because being limited by ocean current, just lose a large amount of more preferable culture resources of water quality give-and-take conditions, simultaneously because above-mentioned The reason for, this kind of net cage can only be used in right up and down inner bay, since raiser swarms in this narrow and small inner bay, be caused Water quality is very severe in gulf, or even stinking smell assaulting one's nostrils, and fish poor quality, fish disease is more, and a most valuable line seascape is lost in coastal city, this Local government is just forced for city development, it has to remove to drive inner bay by force, offshore cage culture family, as Guangdong from west eastwards All clearing up, tolling breakdown inner bay, offshore aquaculture net cage, but because of the technical support used without off-lying sea, this just makes these past fishing The people can catch in no Fish, and the very difficult condition without Hai Kegeng.

From the point of view of Anti-Typhoon situation, every year several ten million science research inputs of country, do not extricate oneself from a plight：

Hainan Lingao entire PLA's destruction, the only economic loss of three companies under typhoon " Ni Ge " attack in by the end of September, (1) 2011 Nearby 800,000,000.

The typhoon of in August, (2) 2013 " especially " blows Guangdong Yangjiang, the destruction of the two ground net cage entire PLA of Raoping, and Guangdong Province five is supported greatly Grow three sufferings in enterprise.

The violent typhoon of in September, (3) 2013 " Lepus " attack Fujian Province, counts according to Administration of Ocean and Fisheries of Zhangzhou City of Fujian Province, when Ground net cage is annihilated, and is caused damages more than 5.6 hundred million yuan.

Typhoon in July, (4) 2014 " Wei Maxun " blow Hainan, the west of Guangdong Province Yuexi place of arrival net cage entire PLA destruction.

Typhoon in October, (5) 2015 " rainbow " blow Zhanjiang, except the destruction of Zhanjiang net cage entire PLA is outer, also bring disaster upon and Haikou, Maoming And Yangxi net cage.

(6) 2016 years Mid-autumn Festival typhoon " Mo Landi " blow Fujian, equally beat all gone.

Cause this Disaster difficulties consequence, it is impossible to it is indivedual accidental the reason for explain, the destruction of overall importance of this band, explanation To examine existing popular HDPE net cages closely again from structure.

Our research conclusion is：This destruction of overall importance has its source in：

A. the missing of basis and anchoring system technology, such as basic mooring force is too small, subtracts power without supporting elasticity and unloads power and arranges Apply.

The intensity and rigidity of b.HDPE net cage components are too poor, and for intensity, HDPE material is less than most common A3 steel 1/10,1/200 of elasticity modulus less than steel, for the mechaanical property of materials, unique advantage is corrosion-resistant in seawater.

C. overall stability is too poor, especially just more prominent when net cage size is larger.

Basis and anchoring system technology are another big systems, should be not covered by another special subject study, this patent.

Anti- ocean current problem has its particularity again, in addition to solving to survive in typhoon, also to solve in the big situation lower structure of flow velocity And cultured fishes adaptability problem.Reasonable combination in the Anti-Typhoon series technique of net cage, is sought a kind of more to pacify by this patent Entirely, it is more reliable, Anti-Typhoon, suitable for ocean current compared with novel net cage anxious and without the open sea area of shield.
