2., because this kind of net cage of above-mentioned reason can only use at right up and down inner bay, because raiser swarms in this narrow and small inner bay, cause water quality in gulf very severe, even stinking smell assaulting one's nostrils, fish poor quality, fish disease is many, and a most valuable line seascape is lost in coastal city.This just forces local government in order to city development, has to go by force to drive inner bay cage culture family, but the technical support because not having open waters to use, this just makes raiser be in very difficult condition.
3. although the tube frame that made by HDPE of floating type HDPE net cage, by arranging note/drainpipe, can be sunken to certain depth, evade the wave stroke that the water surface is maximum before typhoon, unsatisfactory from this net cage capacity of anti-storm of practice:
A.2011 year by the end of September Lingao, Hainan at the fish culture net cage of open waters, at typhoon " Ni Ge " attack under be annihilated, the only economic loss of three companies nearby 800,000,000.
B.2013 August in year typhoon " especially " blow Yangjiang, Guangdong, cause local net cage to be annihilated.
C.2013 violent typhoon in September in year " Lepus " attacks Fujian Province, and according to Administration of Ocean and Fisheries of Zhangzhou City of Fujian Province statistics, local net cage is annihilated.Cause damage more than 5.6 hundred million yuan.
The destruction that this band is of overall importance, illustrating will from the floating type HDPE net cage of re-examine routine structure.
Tension leg type net cage TLC, by tension force, net cage is tightened, make ocean current can not cause the drift of net cage, cage culture is made to hold bulk diffusion, its capacity of anti-storm is also proved from external tension leg type net cage TLC practical manifestation simultaneously, and offshore oil tension type platform structure, as tension type platform, single anchor leg platform, only its theory and practice of pillar platform also illustrates the reliability of its wind wave resistance from another point of view.
In order to break through the limitation of conventional floating type HDPE net cage, seek a kind of safety, reliably, be applicable to the novel net cage in the open sea area of ocean current comparatively suddenly and without shield, just based on tension leg type net cage, the core of its tension force must be got, utilize production equipment and the equipment of conventional floating type HDPE net cage, transformation simultaneously accounts for the HDPE of deep water mesh cage 95%, and the HDPE making the whole nation be worth 10,000,000,000 obtains newborn.
Summary of the invention
In order to break through the limitation of conventional floating type HDPE net cage, seek a kind of safety, reliably, be applicable to the novel net cage in the open sea area of ocean current comparatively suddenly and without shield, just based on tension leg type net cage, the core of its tension force must be got, utilize production equipment and the equipment of conventional floating type HDPE net cage, transformation simultaneously accounts for the HDPE of deep water mesh cage 95%, and the HDPE making the whole nation be worth 10,000,000,000 obtains newborn, and the technical solution of the utility model is:
1, suitable increasing conventional H DPE net cage float tube diameter, net cage net buoyancy is made to be increased to more than needed more than 30%, this part increment is balanced by the gravity ring hung, float tube structure is with four rigid legs and be no less than the flexible tension leg cable of four and gravity ring couples together, gravity ring evenly hangs up pouring weight, constitutes typical tension type structural system;
2 keep floating type HDPE net cages to be equiped with note/draining pipe valve and note/blow off valve to realize the designs such as the design of variable buoyancy function and pipe connections;
3. the gravity ring stretch-draw bottom is prevented swing plate, Fang Dangban can be plank, steel plate, plastic plate or composite material skin, the curtain etc. of curtain formula structure;
4., for convenience of installing, four rigid legs are by sleeve connection, and namely go to sea net cage float tube and gravity ring when installing can overlap;
5. the technical solution of the utility model also contains existing floating type HDPE net cage modification scheme, i.e. the sleeve that passes through of float tube exterior configuration four rigid legs, and adding buoyant mass increases buoyancy.
This technical scheme principle is, wind, wave, the horizontal force H produced under flowing common action, it makes buoyancy aid generation depart from, if the tilting complex torque M-that horizontal force H produces, it is M+ that buoyancy F produces righting moment, and the two is just in time reverse, and namely tension force can make it get back to equalization point by acting in opposition, thus realize dynamic equilibrium, the principle of compliant type anchoring that Here it is.When water level changes, buoyancy changes, and buoyancy aid, together with the upper and lower heave of gravity ring, because anti-on gravity ring swings plate effect, can reduce it and pitch.Before typhoon is attacked, allow it sink by water filling, allow gravity ring touch the end and evade typhoon, after typhoon, gas injection draining allows its floating restore.
The utility model has the advantages that rational in infrastructure, workable, overcome the shortcoming of floating type HDPE net cage completely, maintain again the advantage that floating type HDPE net cage operation interface is good, it is large that this net cage can adapt to waters scope, this is just exploitation ocean current comparatively urgency and the open sea area without shield, and the utilization of culture resources creates condition.
