Abstract

The utility model puts forward a man-made algal reef formed by a base which takes the shape of an actagon and an equilateral trapezoid stage with a octagonal base and a quadrangle top. The utility model comprises: an upper top affixed lamina, an upper slanted affixed lamina, a lower stand fully-affixed lamina, a lower stand semi-affixed lamina, the bottom lacing wire and the framework are connected. The bottom lacing wire is connected with the framework, the side walls of the base are formed by separated lower stand fully-affixed lamina and separated lower stand semi-affixed lamina, the lower stand fully-affixed lamina is adjacent with the lower stand semi-affixed lamina, the frame work whose upper part crosses the bottom part to form a triangle is provided with no affixed lamina. The utility model has the advantages of: mechanically blocking the sea water to flow and making the water flow to form swirls and upward currents which can bring nutritious salt at the seabed to the vicinity of this utility model. For different seaweeds apply different affixed lamina with different roughness to achieve the best seaweed affixing effect.

Description

Frame-type artificial marine alga reef

Affiliated technical field

The utility model relates to the Mechanical Builds that environments such as subsea is transformed, especially a kind of frame-type artificial marine alga reef that is suitable for the marine alga growth.

Background technology

At present, the construction in China offshore fishing grounds to be throwing in modes such as stone and shipwreck, no matter be that the reef of which kind of form is all not fully up to expectations aspect adhering at marine algae.Adhering to of algae is temperature, the intensity of illumination that is subjected to seawater, the influence of the direction flow velocity of ocean current and the factors such as degree of roughness of adherance, adjust flexibly and all can't do on the common artificial reef adaptability in these areas, especially do not seeing relevant report aspect the degree of roughness control of adherance.

Summary of the invention

The utility model proposes a kind of frame-type artificial marine alga reef, can make corresponding adjustment to the marine alga situation of illumination condition, ocean current situation and this area at different sea conditions.

The technical scheme that the utility model adopted is: a kind of frame-type artificial marine alga reef, by the octagonal base and the end be octagon, the top is that tetragonal trapezoid platform is formed, comprise: go up top lamina affixad 1, go up oblique lamina affixad 2, upright down full lamina affixad 3, upright down half lamina affixad 4, bottom lacing wire 5 and framework 6, last top lamina affixad 1, go up oblique lamina affixad 2, upright down full lamina affixad 3 is connected with framework 6 with down upright half lamina affixad 4, bottom lacing wire 5 is connected with framework 6, base side wall is made of non-conterminous down upright full lamina affixad 3 and non-conterminous down upright half lamina affixad 4, upright complete down lamina affixad 3 is adjacent with down upright half lamina affixad 4, and crossing the formation on the leg-of-mutton framework 6 in top and bottom is not covered with lamina affixad.Go up oblique lamina affixad 2, upright full lamina affixad 3 and down upright half lamina affixad 4 are four down, the area of upright half lamina affixad 4 is half of place framework face area down, go up the angle 30-60 of oblique lamina affixad 2 and horizontal plane, described lamina affixad is under different user modes, and roughness is inequality.

Its main body frame is to be that 8 limit shapes top is that tetragonal trapezoid platform constitutes by the octagonal base and the end, and is made of metal angle, around base and four positive directions of halfpace be covered with the surface and handle PVC engineering plastics plate through roughness control.In order to reduce ocean current to impact of the present utility model, there are four blocks of plates to be this half in 8 lamina affixads of base side wall to framework 6 areas, and non-conterminous; Divide to intersect to form on the triangular framing 6 in top and bottom not to be covered with lamina affixad, as water body interchange channel, top and reduce the fluoran stream surface resistance; Last top is covered with lamina affixad 1.Bottom of the present utility model opposite side is done groined type with band steel and is connected, and in order to sandbag or stone reef is fixed.The marine alga lamina affixad uses the PVC engineering plastics, the carrying out that its surperficial degree of roughness control shoots the arrow at the target according to algae situation kind of having grasped and individual size etc., and the notion of introducing roughness does quantitative control, and the angle control between the trapezoid Taiwan Straits, top algae lamina affixad and the horizontal plane is determined according to throwing in the sea area depth of water and ocean current situation.

Beneficial effect of the present utility model is: can mechanical barrier effect be arranged to marine stream, make seawater form vortex and upwelling, the salt that the seabed is nutritious takes near the utility model; At different algal species, use the different attached plate of degree of roughness, obtained best algae adhesion effect, can be to the positive effect of construction performance of " oceanic pasture ".

Embodiment

The utility model has two kinds of materials to constitute, the material of framework is an angle steel, lacing wire 5 materials in bottom are band steel, last top lamina affixad 1, go up oblique lamina affixad 2, upright complete down lamina affixad 3 and down upright half lamina affixad, 4 materials are the PVC engineering plastics, last top lamina affixad 1, go up oblique lamina affixad 2, upright complete down lamina affixad 3 and down upright half lamina affixad 4, the surface is through roughness control processing, its coarse degree is determined by the intrinsic situation of algae of throwing in the marine site, going up oblique lamina affixad 2 is determined by the depth of water and the illumination condition in targeted marine site with the angle of horizontal plane, last top lamina affixad 1, go up oblique lamina affixad 2, be connected by bolt between upright down full lamina affixad 3 and down upright half lamina affixad 4 and the framework 6, bottom lacing wire 5 welds together with framework 6, and framework 6 and bottom lacing wire 5 surfaces scribble antirust paint.
