The principle of sea buoyancy aid, as the inflation ball float in life, can within it be filled with a large amount of Compressed Gas, just can obtain larger buoyancy, then all the more so in water.Sea buoyancy aid is floating across the sea by the buoyancy be subject to, and sea buoyancy aid provides pulling force for whole frame, makes whole frame also can keep not sinking in the seawater, thus provides the concentrated drop spaces of algae brick.Algae brick is after having cultivated marine alga seedling, and marine alga seedling is attached on algae brick, and algae brick is within brick groove, is fixed by fragment of brick cable pull.Marine alga seedling is towards within whole frame; so at initial stage of growth of seedling; marine alga is all within whole frame internal range, only has one of whole frame itself main opening upwards, and has protection outer net; can prevent large fish from invading; therefore seedling is except being concentrated, and also obtain effective protection, fish are difficult to eat these seedling in a large number; and seedling is due to concentrated input, also can monitored growth conditions very easily.And by observing, find when after growth of seedling certain period, it is inner that marine alga starts to be full of whole frame, and now can unload fixture, owing to rotating cylinder wrapped around fragment of brick drag-line, and fragment of brick drag-line is in tension, and therefore rotating cylinder can be hauled rotation, release fragment of brick drag-line.Certainly, in this design, the coiling direction being connected to the fragment of brick drag-line on same rotating cylinder is necessarily consistent, is all clockwise or counterclockwise, otherwise just loses the meaning of winding fragment of brick drag-line.Fragment of brick drag-line is after stretching, extension, extending, algae brick departs from brick groove with connecting a part of marine alga of growth on self brick body, be released to the position apart from whole frame certain length, now, the part marine alga be released out just can obtain better growing space and environment, and marine alga now owing to separating has grown into a certain degree, the ability that opposing fish and sea washes destroy has not been that seedling is small and weak like that for period, and therefore the output of marine alga and follow-up multiplication capacity can be protected.Further, when algae brick is in brick groove, the cell wall of attachment cover brick groove is spacing, is in the position covering director space, now only has foreign minister's opening to can be used for marine alga outwards to extend, have initial stage protected effect; And after algae brick departs from brick groove, spacing disappearance, attachment lid is freely opened, and can provide larger more attachment, growing space, is beneficial to the growth of marine alga.
And in said process, the release of fragment of brick drag-line, can by carrying out at times, in batches.When in body frame during insufficient space, first the fixture on a rotating cylinder can be unloaded, a part of algae brick is allowed to separate, then continue to allow its propagation one end time, to be seen not enough again to space in body frame time, continue the fixture on other rotating cylinder of release, after repeatedly carrying out according to this step, until all separated release of all algae bricks.Fixture in foregoing can be that bolt, static line, pin etc. are arbitrarily conventional is fixedly connected with device, as long as rotating cylinder and main center pillar can be fixed by it.And the existence of weighted spherical ball; the distribution of weight outside whole frame can be balanced; when whole frame is subject to the drive of seawater stream; can have larger rest inertia and good whole machine balancing, prevent whole frame from rolling because of the fluctuating of seawater excessive, weighted spherical ball is also location and the position limiting structure of protection outer net simultaneously; weighted spherical ball utilizes self gravitation to enable the tensioning of protection outer net; make it good overlay on above whole frame, weighted spherical ball is carried out drop-down and spacing to drooping section, make drooping section can not depart from shackle completely.When marine alga grows up to a certain extent; can protection outer net be fastened in upper annular groove; outer net is protected just to be raised a segment distance thus; a segment distance has been there is between protection outer net lower end and whole frame; larger seaweed growth space can be provided, contribute to those marine algas looking fast and continue to outgrowth, elongation.Further, the protection outer net be raised, fastened can reused in the future.
Artificial or semi-artificial sea jungle is generally chosen at coastal waters, and the depth of water is dark, is generally about tens meters to over one hundred rice, and it is complicated and changeable like that environment is also not so good as middle sea, deep-sea, and stormy waves is less at ordinary times, and destructive power is limited.But when having high sea to attack once in a while, the utility model also can rise and fall sharply and quickly along with stormy waves.At ordinary times, due to the Action of Gravity Field of whole frame, push pedal spring is compressed always, when high sea comes interim, anti-billow structure rises fast together with whole frame, but billow is powerful, when fast sea buoyancy aid being pressed down because whole frame declines slow, push pedal spring will promote to promote mainly on plate and move larger distance, and pushes away on spool, and core dop snaps in be received in core groove, spool is fixed, interior feed channel is connected in road by spool Shang Xin, and the gas in the buoyancy aid of sea starts to discharge from check valve, and buoyancy starts to reduce, until be not enough to hold whole frame, whole frame sinks to the seabed of sea jungle.Across the sea; stormy waves maximum be all generally sea or distance sea more nearby; and it is downward along sea; darker position stormy waves is less; therefore whole frame is after sinking, and the high sea impact be subject to around it is just very little, and the marine alga therefore grown on its periphery algae brick is also unlikely to be subject to the too much destruction of high sea; good preservation can be obtained, realize reply high sea time oneself hide, self-protection.When after the high sea past, by showing that a ball float finds whole rack position, whole frame can be regained by long stay cord, and upgrade a sea buoyancy aid or again inflate, and just can continue to allow marine alga carry out good growth and to have bred.The realization of said process, under being based upon the very large prerequisite of stormy waves, if be only that little wind moderate seas are attacked at ordinary times, also have some move up and down although promote mainly plate, but whole frame ascensional range is little, dropping distance is very short, still can keep preferably the lower pulling force promoting mainly plate, and making of providing of wave to promote mainly plate close power relative to spool not enough, promote mainly plate also not have enough time to contact, promote spool, just moved down under the pulling force effect of push pedal spring and resetted, after reset, compressive state got back to by push pedal spring.And only have when stormy waves is very large, ensure that whole frame climb is very large, the speed of whole frame and sea buoyancy aid relative motion enough soon, relative near distance enough greatly, the venting to sea buoyancy aid could be realized.
