Abstract

The utility model discloses a rigid bracket net box, which is provided with a fixed framework, wherein the fixed framework is in a framework structure formed by connecting an outer frame, an inner frame and an upright post, drowned reefs are distributed and arranged between the inner frame and the outer frame along the circumference, the top of the fixed framework is connected with a net box floating frame through a connecting rope, and net clothes are suspended in the net box floating frame. The rigid bracket net box has the advantages of simple structure, novel structure and capability of regulating the water flow rate according to the requirements and is applicable to mass production, and culture bait is saved.

Description

The rigid support net cage

Technical field

The utility model relates to environmental cultivator, relates in particular to the rigid support net cage.

Background technology

Want wealth to the ocean, become the ocean advantage and be economic advantages, be the emphasis that the whole society pays close attention to always.Along with the further raising of living standards of the people, the ratio of aquatic products in resident's food consumption will constantly rise, and aquatic products will be occupied an leading position in non-staple food consumption with animal product in the long term.Aquatic products not only will become people and absorb one of main source of animal protein, and can alleviate that the people subtracts with increasing, the problem of food shortage.Because large quantities of off-lying seas fishing boat pushes to the coastal waters, make originally and can't bear the heavy load more with regard to very fragile inshore fishing, fisherman's opportunity to earn a living is had a strong impact on, and the fishing zone social stability is subjected to serious impact, and the development mariculture has become coastal fisherman one of the most important direction of being transferred to civilian work of changing the line of production.From actual, mudflat aquaculture is the main mode of mariculture always, utilize substantially but can be used for culturing beach at present, and breed variety only is confined to shellfish; Though it is better to enclose pool culture benefit, extensive development will certainly take continental rise in a large number influences the other industries development, also is unfavorable for the ecological balance and environmental protection; The wind wave resistance of littoral traditional cage culture flows poor performance, carrying capacity is little, service life is short, culture the sea area limitation greatly, easily disease takes place, and the environmental pollution of culturing self is very serious.Therefore, strengthening the innovation dynamics of modern marine cultivation project technology, keep the sustainable sound development of mariculture, has been extremely urgent.

Summary of the invention

The purpose of this utility model is a kind of Stability Analysis of Structures to be provided, the rigid support net cage of regulating discharge, novel structure as required, being suitable for producing in batches, saving breeding bait can be arranged at prior art.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the rigid support net cage, and it has fixed frame; Fixed frame connects into frame structure by housing, inside casing and column; Between inside casing and housing, be laid with heavy reef along circumference; The fixed frame top is connected with the floating frame of net cage through connection cord; Hang etting in the floating frame of net cage.The effect that heavy reef is set between the fixed frame is to stablize whole rigid support net cage.

For optimizing technique scheme, the measure of taking also comprises: heavy reef upper edge fixed frame radially is shaped at least one duct; Heavy reef also is shaped at least ten through holes.Duct can be introduced the major part of current and run through outflow, can reduce the impact of current to the heavy reef of the utility model, can also increase the discharge of fixed frame inside, increases the dissolved oxygen of the etting inside that hangs in the floating frame of net cage, helps cage culture.Through hole can play the similar effect of fish shelter, and the accumulation natural bait, saves the abundance of food of manually throwing something and feeding when culturing, and lowers aquaculture cost.

Also be shaped on the connecting ring that can be connected on the heavy reef with column.Can increase or reduce the quantity of heavy reef in the fixed frame as required at any time, adjust the natural bait amount and according to the spatial distribution situation of the heavy reef of streamflow regime adjustment with bar.

Because the utility model rigid support net cage has adopted fixed frame to connect into frame structure by housing, inside casing and column; Between inside casing and housing, be laid with heavy reef along circumference; The fixed frame top is connected with the floating frame of net cage through connection cord; Hang etting in the floating frame of net cage, it has Stability Analysis of Structures, the advantage of regulating discharge, novel structure as required, being suitable for producing in batches, saving breeding bait can be arranged.

Fig. 2 is the heavy reef perspective view of the utility model embodiment cultivator.

Embodiment

Below in conjunction with attached embodiment the utility model is described in further detail.

Drawing reference numeral explanation: fixed frame 1, housing 11, inside casing 12, column 13, heavy reef 2, duct 21, through hole 22, connecting ring 23, the floating frame 3 of net cage, connection cord 4.

Embodiment: referring to figs. 1 through Fig. 4, the rigid support net cage, it has fixed frame 1; Fixed frame 1 connects into frame structure by housing 11, inside casing 12 and column 13; Between inside casing 12 and housing 11, be laid with heavy reef 2 along circumference; Fixed frame 1 top is connected with the floating frame 3 of net cage through connection cord 4; Hang etting in the floating frame 3 of net cage.Heavy reef 2 upper edge fixed frames 1 radially are shaped at least one duct 21; Heavy reef 2 also is shaped at least ten through holes 22.Also be shaped on the connecting ring 23 that can be connected on the heavy reef 2 with column 13.Can adopt rope that fixed frame 1 is fixed on the sea bed at heavy reef 2 more after a little while.The effect that heavy reef 2 is set between the fixed frame 1 is to stablize whole rigid support net cage.Duct 21 can be introduced the major part of current and run through outflow, can reduce the impact of current to the heavy reef 2 of the utility model, can also increase the discharge of fixed frame 1 inside, increases the dissolved oxygen of the etting inside that hangs in the floating frame 3 of net cage, helps cage culture.Through hole 22 can play the similar effect of fish shelter, and the accumulation natural bait, saves the abundance of food of manually throwing something and feeding when culturing, and lowers aquaculture cost.The utility model can increase or reduce the quantity of heavy reef 2 in the fixed frame 1 as required at any time, adjusts the natural bait amount and according to the spatial distribution situation of the heavy reef 2 of streamflow regime adjustment with bar.

Although described the utility model in conjunction with preferred embodiment; right its is not in order to limit the utility model; any those skilled in the art; under the situation that does not break away from spirit and scope of the present utility model; can implement the displacement and the modification of various changes, coordinate to the theme of listing here, therefore protection domain of the present utility model is as the criterion when looking the claim restricted portion that is proposed.
