Description
Technical field
The utility model relates to the utensil field of aquaculture, relates more specifically to a kind of floating type fish culture net cage.
Background technology
China is the country that unique in the world cultured output surpasses fishery output, aquaculture in the national economy life in occupation of important position.Along with the adjustment of fishery structure, irreversible to culture alternative trend of fishing for.
Fish culture in net pen is the ecotope that utilizes big water body good, obtains a kind of breeding way of high yield in conjunction with little water body dense stocking measure.The fish culture net cage of prior art mainly comprises following two kinds of net cages: conventional small timber structure net cage and software net cage under water.
Though conventional small timber structure net cage is cheap, easy to make, be easy to penetration and promotion, yet but have many deficiencies and limitation: 1) the wind wave resistance performance is on duty mutually, can only be confined to wind sheltering condition surface waters preferably, very easily cause problems such as the cultivation density of culturing the marine site is too high, the breed fishing ground is aging and the aquatic products disease takes place frequently; 2) inner bay water is shallow, and the water body exchange capacity is relatively poor, and even without the secondary pollution of aquaculture self, the inferior quality of propagating and culturing fingerling artificially that has also limited many famous and precious fish of the water quality that pollution from land-based sources causes descends; 3) service life is short.
The software net cage is a kind of improvement to conventional small timber structure net cage under water.This net cage is complete flexible, and structure is formed the tension force system by vertical steel cable and horizontal steel loop, and outward appearance is seemingly spun mallet shape, and total length 16.8m, maximum gauge 1.5m, breeding water body are about 33 cubic metres.Compare with traditional floating raft type timber structure net cage, the software net cage has good HYDRODYNAMIC CONDITION RELATING TO under water, stronger capacity of anti-storm, and also easy to make, economical.But in use find to have following shortcoming: net cage is full flexible structure, is easy to generate distortion, thereby effective breeding water body is reduced; The material of cage structure falls behind, easy-to-rust, poor durability; The facility that do not rise and fall, submerged is unfavorable for the growth of fish for a long time, operation labour intensity is bigger in the time of need emerging.
The utility model content
The purpose of this utility model provides a kind of floating type fish culture net cage, have simple in structure, capacity of anti-storm is strong, preparation cost is low and advantage such as applied widely.
For achieving the above object, the utility model provides a kind of floating type fish culture net cage, comprise main body and the device that drifts along, described main body comprises support frame that is welded by round steel and the etting that is connected on the described support frame, the described device that drifts along comprises ball float, HDPE pipe and sinker, described HDPE pipe is by fixedlying connected with described round steel so that described main body is bubbled through the water column, described ball float and sinker are contained in respectively on the headline and infraclass of described main body, by controlling described ball float and sinker to control the sink-float of described main body.
Preferably, the support frame of described main body is formed by connecting by the sections framework that multistage is cylinder body shape, and the cross section of each sections framework is rectangle and fan-shaped combination.
Preferably, the support frame of described main body is formed by connecting by eight sections sections frameworks that are cylinder body shape, and described sections framework compartment of terrain is equipped with a described ball float and a sinker, and the etting on the described sections framework also is provided with a bait throwing in fish outlet in the compartment of terrain.
Preferably, the effective foam of described HDPE tamps, and two ends are sealed with plug; And described HDPE pipe is fixed by rope and described round steel colligation.
Preferably, coating is carried out with epoxy resin in described round steel surface, and gauze is twined with epoxy resin impregnated back; Described etting is a nylon mesh sheet; Described sinker is a concrete cube.
Compared with prior art, the utility model floating type fish culture net cage adopts flexible material HDPE pipe and round steel as support frame, can guarantee that structure has the high-intensity while, has very big deformability, according to calculating the positive effect that can resist 12 grades of typhoons; And, implement simple, convenient and easy by the sink-float that ball float, HDPE pipe and sinker three control net cage.Under the normal condition, net cage is bubbled through the water column; When running into typhoon, net cage is sunk under the water, can cut down or avoid fully the destruction of stormy waves.
By following description also in conjunction with the accompanying drawings, it is more clear that the utility model will become, and these accompanying drawings are used to explain embodiment of the present utility model.
