Description

Trapezoidal-structure juvenile fish care reef with plum blossom holes

Technical Field

The utility model relates to the technical field of aquaculture, artificial fish reefs and marine pastures, in particular to a trapezoidal-structure juvenile fish care reef with plum blossom holes.

Background

In areas with severe wind direction and tides, irregular occurrence of big tides and small tides and extremely complex sea conditions, particularly in some shallow reef sea areas with lower water depths, in order to improve the retention rate of young fish in local small habitats, a fish reef with good stability and convenient for young fish to perch on rope bait needs to be designed.

Disclosure of Invention

Aiming at the problems existing in the prior art, the utility model provides a trapezoidal-structure juvenile fish care reef with plum blossom holes, so as to solve at least one of the technical problems.

The technical scheme of the utility model is as follows: the utility model provides a trapezoidal structure juvenile fish care reef with plum blossom hole, includes fish reef main part, its characterized in that, fish reef main part includes a roof, a bottom plate and four are trapezoidal curb plates, be equipped with around the bottom plate be used for with curb plate bottom fixed mounting groove, be equipped with around the roof be used for with the top joint of curb plate spacing protruding, the top of curb plate is equipped with mounting groove assorted mounting protruding, the top of curb plate be equipped with spacing protruding assorted spacing groove, roof, bottom plate and curb plate concatenation constitute a hollow fish reef that is trapezoidal structure;

the side plates and the top plate are respectively provided with six plum blossom holes, each plum blossom hole comprises a first plum blossom hole and a second plum blossom hole, the first plum blossom holes are arranged in the center of the side plate and the center of the top plate, the second plum blossom holes are at least four, the second plum blossom holes are distributed around the outer edges of the first plum blossom holes, and the central channel width of the first plum blossom holes is larger than that of the second plum blossom holes.

Firstly, the design of the trapezoid structure has the advantages that the lower part of the trapezoid is wide, the upper part of the trapezoid is short, the stability of the fish reef can be kept due to the fact that the lower part of the trapezoid is wide, vortex is formed under the complex flow condition due to the fact that the trapezoid edge of the short edge of the upper part of the trapezoid is designed, various small floating animals are gathered, young fish which take the small floating animals as food are trapped inside the fish reef, and therefore the purposes of avoiding enemy and being convenient for feeding are achieved. Six-petal plum blossom hole designs purpose, and the fish reef is convenient from the practicality inside and outside to get in and out, and especially various length, big or small fish get into, forms unique habitat. The six-petal plum blossom design can enable the plum blossom structure to form vortex better when the ocean current impacts the fish reef, and the plankton suspended in the seawater is reserved inside and outside the reef body, so that young fish in the fish reef can conveniently carry out rope bait. The middle plum blossom holes can enable a slightly larger individual fish to pass through without barriers, so that the fish reef is suitable for various fishes within a certain body length range, and the application range and the application area of the fish reef product are enlarged.

Further preferably, the top plate and the bottom plate are square plate bodies. Thereby the fish reef body can be placed more stably.

Further preferably, the thickness of the side plate is greater than the thickness of the top plate and the thickness of the bottom plate respectively, the limiting protrusions are vertically fixed around the top plate, the installation direction of the limiting protrusions faces the outer side of the top plate, and the installation protrusions are fixed on the lower surface of the side plate.

The utility model is convenient to detach and transport in a splicing mode, reduces the transportation cost, automatically inclines inwards by utilizing the self weight of the side plate after the bottom is fixed, clamps the limiting bulge of the top plate in the limiting groove, and can reduce the front impact of sea waves under the action of the plum blossom holes.

Further preferably, the side plate is in an isosceles trapezoid shape, and the mounting protrusion and the limit groove are located at the center line of the side plate.

Thereby enabling an overall stability to be improved.

Further preferably, the thickness of the side plate is gradually increased from top to bottom. The stability is improved, and the impact force of sea waves can be better resisted.

Further preferably, the inner wall of the first plum blossom hole is provided with strip-shaped grooves which are arranged in a spiral mode, and the depth of each strip-shaped groove gradually increases from outside to inside.

The strip-shaped grooves are added, so that larger vortex can be generated, and various small floating animals are gathered.

Further preferably, the number of the second quincuncial holes is 4, 6 or 8, and the second quincuncial holes are symmetrically arranged around the first quincuncial holes along the central line.
