Description
Technical field
The invention belongs to sea farming device technique field, particularly a kind of propagation type artificial fish shelter be suitable at the bottom of reef.
Background technology
Artificial fish shelter is the structure artificially arranged in the seawater; it is that artificial material is sunk to seabed; it is utilized to assemble numerous halobiontic attachment as adherance; improve the ecotope of offshore sea waters; build the good environment that marine organisms perch; there is provided breeding, growth, forage for fish etc. and shelter the place of enemy, reaching protection, breeding and improve the object of catch.
But current manual's fish shelter is primarily of the hollow polyhedral of cement production systD, and because volume ratio is comparatively large, in reef matter seabed, hard cement surface is difficult to firmly embed in reef matter, easily rolls under ocean current and wind wave action; Meanwhile, because cement prefab surface is in strong basicity, marine organisms are difficult to quick apposition growth, and this is unfavorable for the improvement at fish stock increasing and ecotope of artificial fish reef area.Therefore, how to improve artificial fish shelter generally exist in reef matter seabed capacity of anti-storm weak, easily by the problem that stormy waves washes away, marine organisms quick attachment issue on artificial fish shelter can be made again to be one of difficult problem in fish stock increasing simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of propagation type artificial fish shelter be suitable at the bottom of reef, is suitable for the marine site that the seabed such as the rice of the 5-10 under water degree of depth, coastal waters reef matter situation is complicated, silt stormy waves is large being laid in aquaculture district and Fishing area.This artificial fish shelter is thrown in simple, and steadiness is good, is conducive to halobiontic apposition growth, has higher replicability.
For achieving the above object, the utility model is achieved through the following technical solutions: a kind of propagation type artificial fish shelter be suitable at the bottom of reef, comprise square framework 1, linkage unit 2 and outreach unit 3, described square framework 1 is made up of some prisms, the cross section of described prism is base and high length ratio is the isosceles triangle of 1:2, the inside and outside both sides of described prism are provided with linkage unit 2, described in outreach unit 3 and be connected with linkage unit 2, and outreach unit 3 not in same level.
Concrete, described linkage unit 2 is several connecting rings or hangers.
Concrete, it is affixed that described connecting ring or hangers pass through adhesive or cement and prism, or directly fasten on prism.
Concrete, described in outreach that unit 3 is rope, one or several in braid, fishing net.
Compared with prior art, the utility model has the following advantages:
1. assembling is simple, and cost is low, and space availability ratio is high, can embed and fasten seabed reef, have the effect of wind wave resistance.
2. permeability is good, is easy to inside and outside water coke slurry, and whole mesh space is conducive to halobiontic apposition growth, thus improves surrounding enviroment, allows the fish young can hide, free shuttling wherein, improves poly-fish amount.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
In figure: 1, square framework; 2, linkage unit; 3, unit is outreached.
Embodiment
A kind of propagation type artificial fish shelter be suitable at the bottom of reef, comprise square framework 1, linkage unit 2 and outreach unit 3, described square framework 1 is made up of prism, the cross section of described prism is base and high length ratio is the isosceles triangle of 1:2, the inside and outside both sides of described prism are provided with linkage unit 2, the described unit 3 that outreaches is connected with linkage unit 2, and outreaches unit 3 not in same level.Described linkage unit 2 is several connecting rings or hangers.It is affixed that described connecting ring or hangers pass through adhesive or cement and prism, or directly fasten on prism.Describedly outreach that unit 3 is rope, one or several in braid, fishing net.Thus form the 3 D stereo network structure of single artificial fish shelter.Consider that artificial fish shelter easily rolls in reef type seabed, therefore, the artificial fish shelter of design is square frame structure, only has rib and does not have face, and the prism of isosceles triangle shape not easily rolls in use.Meanwhile, by outreaching unit 3 connection, whole artificial fish shelter surface and inside promote that marine organisms are at the apposition growth on its surface.
Inside and outside framework in each square prismatic frame structure, both sides are respectively containing multiple connecting ring or hangers, by outreaching engaging lug on unit 3 pairs of polyhedron prismatic frameworks or hangers connects.Wherein, outreach the unit 3 mainly rope of nylon-type and braid, fishing net, connecting ring or hangers be ears highstrenghtpiston, fishing gear, fishing net, precast reinforced concrete part, rope etc. mainly, by being connected to form in reefs spatially cancellated artificial fish shelter.The assembling of this structure is simple, and cost is low, and space availability ratio is high, and frame structure makes embed at the bottom of artificial fish shelter and be buckled on reef, has the effect of wind wave resistance.Reefs is inside and outside by connections such as rope bodies, spatially network structure surface, the described unit 3 that outreaches is not in same level, ensure that the permeability of whole artificial fish shelter is good, promote inside and outside water coke slurry, whole mesh space is conducive to halobiontic apposition growth, thus improves surrounding enviroment, allow the fish young can hide, free shuttling wherein, improve poly-fish amount.Through model test and numerical simulation, this propagation type artificial fish shelter, be suitable for throwing in the marine site to depth of water 5-10 rice, can not to topple displacement, be conducive to a large amount of algae, shellfish, bryozoan, etc. quick apposition growth on artificial fish shelter, can be the concealment such as stichopus japonicus, grouper biology and safe and reliable habitat and bait field are provided, be suitable for the stop of shuttling back and forth of large, medium and small fish, flow field effect is better, and wind wave resistance, there is good economic benefit, therefore can be widely used in the construction of artificial fish shelter.
Embodiment of the present utility model is not limited thereto; under above-mentioned basic fundamental thought prerequisite, according to the ordinary technical knowledge of this area and customary means to the utility model content make other various ways amendment, replacement or change all drop within the utility model rights protection scope.
