Description

Proliferation type umbrella-shaped artificial fish reef monomer

Technical Field

The invention belongs to the field of aquaculture, and particularly relates to a multiplication type umbrella-shaped artificial fish reef monomer.

Background

The artificial fish reef is a structure which is scientifically selected and arranged by people in the sea, aims to improve the ecological environment of sea areas, provides necessary and safe inhabitation places for gathering, baiting, breeding, growing and avoiding enemies of aquatic organisms such as fish and the like, and achieves the purposes of protecting and proliferating fishery resources and increasing the harvest yield. The artificial fish reef can also change the flow direction and the flow velocity of ocean current to generate ascending vortex, back vortex and the like, so that nutritive salts at the sea bottom are turned and diffused, and abundant nutritive substances at the sea bottom are transmitted to each layer of a water body along with the ocean current, so that the distribution of the nutritive substances in the sea water is obviously improved, aquatic organisms such as fishes and the like are attracted to seek for food and stay, and the formed fishing operation place for concentrating and stabilizing the aquatic organisms such as the fishes and the like is formed. After the artificial fish reef is arranged on the seabed, the artificial fish reef is subjected to external force such as waves and currents, must be kept stable, cannot be flushed, cannot slide and cannot be overturned, particularly sea reef monomers for breeding sea cucumbers, abalones and the like are required to be capable of resisting the external force acting on the artificial fish reef without being damaged, and a larger area for the sea cucumbers, the abalones and the like to be attached is provided. However, if the shape and structure of the reef are too complicated, the gap is small, the attached biomass is large, oxygen is insufficient, light is weak, and the life is not facilitated.

Disclosure of Invention

The invention aims to provide a proliferation type umbrella-shaped artificial fish reef monomer which is stable in seabed structure, has through water flow and is beneficial to the attachment and growth of organisms.

The invention is realized by the following technical scheme:

the utility model provides an artificial fish reef monomer of proliferation type umbrella form, the fishing reef monomer include reef piece and the arris more than 8, the reef piece on parallel relatively place down, and between two liang of reef pieces more than vertical distance 10cm, the reef piece diameter grow in proper order from top to bottom, support through the oblique arris of fixing at reef piece edge top-down between two liang of reef pieces. The maximum vertex angle formed by the two opposite edges is 30-170;

furthermore, the vertical height of the fishing reef monomer is 1.0-5.0m, and the spacing between reef slices is 10-50 cm.

Furthermore, the reef plate is in a disc shape, a disc shape or a basket shape.

Furthermore, the edge is longer than the lowermost reef plate by more than 1 m.

Further, when the seabed is a muddy bottom, the projection area of the lowermost reef is more than 10m²Otherwise they will easily silt into the sea floor.

According to the method for putting the fishing reef monomer, the size of the maximum vertex angle formed by two opposite edges is designed according to the difference between the water flow size and the bottom material of the water area where the artificial fish reef is placed, the water flow is small, the bottom material is soft, and the maximum vertex angle is large; the water flow is large in bottom hardness, and the maximum vertex angle is small; embedding the edge below the fishing reef monomer into the seabed with the water depth of 5-50m, and if the sea is sandstone, the distance between the lowermost reef plate of the fishing reef monomer and the seabed is more than 0.5m when the edge lands; if the fish reef is arranged on the soft soil, the grounding pressure is reduced to ensure that the reef surface contacts the ground. The fish reef monomer does not slide or overturn.

Compared with the prior art, the invention has the beneficial effects

The invention is provided with more than 8 ribs of the outer wheel, the wave impact resistance of the conical umbrella-shaped artificial fish reef monomer is improved, so that water flow can be upwards conducted along the umbrella-shaped structure, and the waves have no force points in the structure, so that the conical umbrella-shaped artificial fish reef monomer can bear the tide of 1m/s-3 m/s.

The fishing reef monomer is provided with more than 8 ridges (also called feet) to land, so that the fishing reef monomer is good in stability in seawater and can be placed singly, and the technical problem of unsmooth water flow caused by the stacked placement of fishing reefs in the prior art is solved.

Drawings

FIG. 1 is a schematic structural view of the present invention: 1. reef slices, 2, arris.

Detailed Description

The technical solution of the present invention is further explained by the following examples, but the scope of the present invention is not limited in any way by the examples.

Examples

The utility model provides an artificial fish reef monomer of proliferation type umbrella shape, as shown in figure 1, the fish reef monomer include 3 reef pieces 1 and 8 arris 2, so also can set up the reef piece of other quantity and the arris more than 8, the more the reef monomer of arris is more firm in the sea water. Reef piece upper and lower parallel place relatively, and perpendicular distance 25cm between two liang of reef pieces, this distance can set up according to the degree of depth of sea water, the interval is big more rivers more unblocked. The reef piece diameter from top to bottom is the grow in proper order, supports through fixing the oblique arris at reef piece edge top-down between two liang of reef pieces. The maximum apex angle formed by two opposite edges is 60 degrees, and the edges are longer than the lowermost reef plate by 1.2 m. The reef was of disc-shaped, reinforced cement construction (HPB235 rebar, 52.5 cement). The device is placed in the sea area near Langya Zhezhitang island in the yellow island area of Qingdao, the sea area is probed with water of 10m, the wave height is 3m, the wavelength is 72 m, the period is 7 seconds, the tide is l m/s, and the sand ground plate is formed. The artificial fish reef is stable, does not slide, is not overturned or damaged after being arranged on the seabed for 2 years, and is attached with a large amount of sea cucumbers and abalones.
