Description
Technical field
The present invention relates to artificial algal reef technical field, particularly relate to a kind of concrete protective reef.
Background technology
Artificial algal reef is the artificial reef body for cultivating, breeding algae vegetation, that people is for rendering to ocean, river, Hu Bozhong, for algae provides the place of growth, breeding, the vigorous energy of algae vegetation growth attracts the forage of various aquatic animal, breeds, perches, thus reach optimization environments such as subsea, the object of protection propagation fishery resources; Algae can carry out photosynthesis simultaneously, is seawater complement lysis oxygen, can also absorbs the heavy metal in water; purifying water body, protection water environment, on the other hand; a lot of marine alga also has edible, medical value, and such as sea-tangle, laver etc. can be used for eating, and also has some algae can manufacture various skin care item.But algal reef drops into the seawater initial stage, the marine alga seedling on the cultivation substrate on algal reef is easily eaten by marine organisms, thus causes marine alga cannot normal proliferative.
Chinese patent Authorization Notice No.: CN203608659U, authorized announcement date on May 28th, 2014, discloses a kind of artificial algal reef, comprise base and metal framework, base is a truncated rectangular pyramids structure, and metal framework is embedded in base top, framework is fixed with the seedling rope for fixing marine alga; Base is formed by concreting, parallel embedded two pipes in base lower end; Metal framework is hexahedron steel bar framework structure, upper surface and lower surface diagonal by bar connecting, in the vertical reinforcing bar extend through frame lower surface inserted base of framework.Marine alga Seedling Stage lacks the protection to marine alga, thus causes marine alga seedling just by fish predation, has a strong impact on marine alga propagation.
Summary of the invention
The present invention, in order to solve the aforementioned problems in the prior, provide and marine alga seedling can be protected from fish predation at marine alga Seedling Stage, impels the concrete protective reef of marine alga fast breeding.
To achieve these goals, the present invention adopts following technical scheme:
A kind of concrete protective reef, comprise algal reef matrix, be positioned at the some auxiliary reef base around algal reef matrix, described algal reef matrix, auxiliary reef base is made up of concrete, algal reef matrix is cylindrical, auxiliary reef base is circular arc, fit outside the intrados of auxiliary reef base and algal reef matrix, the ends contact of adjacent two auxiliary reef bases, the end face of each auxiliary reef base is respectively equipped with separation net, connected by soft magnetic bodies magnetic absorption between adjacent two pieces of separation nets, all separation nets are connected to form closed Isolation net cover, described algal reef base bottom is provided with some link slots, the metallic rod be easy to by seawater corrosion is provided with in each link slot, the downside of link slot is provided with balancing weight, described balancing weight is provided with the connecting ring be set in metallic rod, the side of algal reef matrix is provided with connecting hole, the side of described auxiliary reef base is provided with the joint pin stretched in connecting hole, the bottom of described link slot is provided with the pin-and-hole through with connecting hole, described joint pin is provided with spacing hole, spacer pin is provided with in described pin-and-hole, the upper end of spacer pin penetrates in the spacing hole on joint pin, the lower end of spacer pin is connected with connecting ring, the bottom of described auxiliary reef base is connected by cable wire with between algal reef matrix side, the inside of described algal reef matrix is provided with air storing cavity, the inside of described auxiliary reef base is provided with closed cavity.
After algal reef is thrown in, Isolation net cover covers marine alga seedling, prevent marine alga seedling from being eaten by fish, marine alga seedling grows up in Isolation net cover, when after certain hour, metallic rod is by seawater corrosion, connecting ring and metallic rod are thrown off, balancing weight sinks, while sinking, spacer pin is extracted in pin-and-hole, assist and lose spacing between reef base with algal reef matrix and be separated, each auxiliary reef base is respectively to expanding outward and being distributed under the effect of cable wire around algal reef matrix, when separation, every sheet separation net is pulled open, prevent separation net from limiting the growth of marine alga; The input initial stage; algae on algal reef matrix, auxiliary reefs is in Seedling Stage; flock together and protected by Isolation net cover; prevent from being washed away by wave and being eaten by fish, along with the growth of algae, more long more intensive; now need larger growing space; auxiliary reef base and algal reef Matrix separation, for algal grown provides more wide space, thus be convenient to algae fast breeding.
As preferably, the downside of described algal reef matrix is also provided with fish shelter matrix, the lower end of described balancing weight is fixedly connected with the end face of fish shelter matrix, the upper end center of described fish shelter matrix is provided with winding roller, winding roller is wound with steel strand wires, the outer end of described steel strand wires is connected with algal reef base bottom, and described algal reef matrix, auxiliary reef base end face are provided with the plate for cultivating algae.Fish shelter matrix is connected with balancing weight, after connecting ring and metallic rod are thrown off, fish shelter matrix sinks to seabed together with balancing weight, fish shelter matrix is connected with algal reef matrix by steel strand wires simultaneously, the degree of depth keeping fish shelter substrate to leave sea is stablized, thus also can prevent fish shelter matrix, auxiliary reef base washed away by wave.
As preferably, described metallic rod comprises stainless steel, the carbon steel bar coaxial with stainless steel, one end and the link slot side of described stainless steel are hinged, the outer end of stainless steel is provided with locating hole, described one end of carbon steel bar is fixedly connected with the opposite side of link slot, and the outer end of carbon steel bar is provided with the positioning boss stretched in locating hole.Stainless steel, carbon steel bar form galvanic corrosion after connecting in the seawater, in galvanic corrosion, carbon steel bar is as anode, very easily corrode, corrosion rate is fast, and the diameter of carbon steel bar can be selected with control corrosion rate time qualitatively, when after the corrosion of carbon steel bar, connecting ring on fish shelter matrix and algal reef depart from, and fish shelter matrix sinks to seabed, mode by experiment can control the etching time of carbon steel bar qualitatively and algae is in Seedling Stage around.
As preferably, in described fish shelter matrix, be provided with some horizontal through holes radially run through, be provided with in fish shelter matrix with axially parallel and run through the vertical through hole of horizontal through hole.The various horizontal through hole of fish shelter intrinsic silicon, vertical through hole are crisscross, form the complicated space be convenient to fish and hidden, grow.
