Abstract

The utility model discloses an artificial algae farm. The artificial algae farm is characterized by comprising a plurality of algal reefs which are connected together through fixing ropes, seedling hanging nets are fixed between the algal reefs, adult algae is hung on the seedling hanging nets, and algae seedlings are attached to the algal reefs. The algal reefs and the seedling hanging nets are combined, the algae seedlings and adult algae are imported to the seabed at the same time, the import effect of the algae is guaranteed, the construction period of the algae farm is shortened, required construction materials are cheap and easy to obtain, the density of the imported algae is greatly increased by hanging the seedlings on the polyethylene nets, the capacity of being prevented from being eaten by organisms is improved, the algal reefs are sequentially connected together through the fixing ropes, the capacity of resisting wind wave is improved, the mode that main reefs and auxiliary reefs are combined is adopted for the algal reefs, and therefore the algal reefs are convenient to carry, work amount is reduced, and the construction success rate of the algae farm is greatly increased.

Description

A kind of artificial algae field

Technical field

The utility model relates to a kind of artificial algae field and building method thereof.

Background technology

Algae field is the important component part of marine ecosystems, can be that multiple marine organisms provide habitat, lay eggs, raise an infant, forage and keep away enemy's place, to improving around flow field environment, reduce seawater loads of nutrition, suppress red tide plankton, improve the solid carbon ability in ocean etc. and there is important Ecology Action.But, the natural algae of China's offshore field serious degradation since the eighties in last century, mainly result from reclaim fields from the sea, pollution from land-based sources, irrational fish production etc.Therefore, the repair and reconstruction work of algae field is very urgent.At present, mainly to build artificial algae field to the recovering method of algae field, ocean both at home and abroad, the construction method of artificial algae field is more, mostly be to adopt seedling rope clamp seedling then to utilize stone or steel nail seedling rope to be fixed on to the method in seabed, all that single introducing becomes algae or seedling, introduce poor effect, the cycle that builds algae field is longer, the fixing workload of steel nail is larger in addition, the stone of fixing seedling rope is easily subject to Lidar Equation and moves, and seedling rope extension seedling density is less, the ability of bearing the biological food evil of algophagous is low, thereby the success rate that algae field is built reduces greatly.

Utility model content

The purpose of this utility model is to provide a kind of artificial algae field and building method thereof, and it can make up the above-mentioned deficiency of prior art effectively.

The technical solution of the utility model is as follows:

A kind of artificial algae field, is characterized in that, comprises some algal reefs that link together by static line, the fixing seedling net of hanging between algal reef, and extension seedling hangs with marine alga on the net and becomes algae, has marine alga seedling on algal reef.

Described algal reef comprises female reef and Zi Jiao, and described female reef is a solid truncated rectangular pyramids, and described sub-reef is the bottom surface quadrangular consistent with truncated rectangular pyramids upper surface size and shape, and sub-reef is fixed on truncated rectangular pyramids upper surface.

Center, four sides of described truncated rectangular pyramids is inlaid with retainer ring, and described static line two ends are fixed on retainer ring.

The rectangular arrangement of described algal reef, four summits of described extension seedling net are separately fixed on the retainer ring of four algal reefs.

The upper surface center of described female reef is inlaid with bolt, and it is corresponding with bolt that sub-reef is provided with centre bore, and sub-reef passes through bolted.

Described female reef and sub-reef form by concreting.

Described extension seedling net is area 20m ²～100m ², the rectangle woven polyethylene net that mesh aperture is 5～15cm.

The construction method of above-mentioned artificial algae field, sub-reef with marine alga seedling is fixed on female reef, throw in seabed, then with static line, each algal reef is connected in turn, be arranged in rectangle, then become four summits of the extension seedling net of algae to be tethered to respectively on four algal reef retainer rings by hanging with marine alga, make whole rectangle hang the tension of seedling net and spread out.

The utility model adopts algal reef and hangs the form that seedling net combines, by marine alga seedling with become algae to introduce seabed simultaneously, guarantee the introducing effect of marine alga, shorten the construction schedule of sea jungle, required structure material cheapness, be easy to get, utilize polythene net to hang seedling and greatly improved the density of introducing marine alga, improve the ability of the biological food evil of tolerance, utilize static line that each algal reef is connected in turn, improve the ability of storm resisting, algal reef adopts the form of female reef and sub-reef combination, be convenient to carrying, reduce quantities, the success rate that algae field is built improves greatly.

Embodiment

Embodiment:

Artificial algae field of the present utility model as shown in Fig. 1,2,3 and 4, comprises and hangs seedling net 100 and algal reef 200, hangs with marine alga and become algae on extension seedling net 100, has marine alga seedling on algal reef 200.Algal reef comprises female reef 220 and sub-reef 210, centre bore 250 on bolt 240 and sub-reef that sub-reef 210 is inlayed by female reef 220 upper surface centers is fastened on female reef 220, between algal reef, interconnect by static line 300, four summits that hang seedling net 100 are separately fixed on the retainer ring 230 of 4 algal reefs 200.Hanging seedling net 100 is area 20m ²～100m ², the rectangle woven polyethylene net that mesh aperture is 5～15cm.

When implementing, sea area first the sub-reef 210 with marine alga seedling is fixed on female reef 220, throw in seabed, then with static line 300, each algal reef 200 is connected in turn, be arranged in rectangle, then become 4 summits of the extension seedling net of algae to be tethered to respectively on 4 algal reef retainer rings 230 by hanging with marine alga, make whole rectangle hang 100 tensions of seedling net and spread out, multiple construction unit expansions are come and have just been formed artificial algae field.

The above is preferred embodiment of the present utility model, but the utility model should not be confined to the disclosed content of this embodiment.Do not depart from the equivalence completing under principle disclosed in the utility model so every or revise, all falling into the scope of the utility model protection.
