Abstract

The utility model relates to a novel fish-cultivation meshy case with an anti-contamination function, which is characterized in that the connecting place of an edge mesh and a bottom mesh of the meshy case is connected with a dirt-gathering pocket; the dirt-gathering pocket forms a bucket shape, and is made from fine cellulose material which is adopted in the utility model; the periphery of the bottom surface of the dirt-gathering pocket forms a certain angle with the bottom mesh of the meshy case, and the lowest place of the dirt-gathering pocket keeps a maximal distance to the bottom mesh. The novel fish-cultivation meshy case with an anti-contamination function of the utility model can make residual feed and fish manure falling from the bottom mesh of the meshy case gathered in the dirt-gathering pocket, and can eliminate the pollutant by a regular pollution discharging mode so as to reach the purpose of preventing water area pollution better. Meanwhile, the utility model also has the advantages of simple structure, easy production and low cost, and overcomes the shortage of the prior art.

Description

A kind of have a novel fish culture cage that prevents to pollute function

The utility model relates to a kind of floating cage that is mainly used in seawater or fresh-water fish-culture, specifically refers to a kind of novel fish culture cage that prevents to pollute function that has.

On the sea or the fresh water water surface adopt floating or submerging cage to culture various fish, be a comparatively ripe and widely used artificial culture technology, particularly comparatively general in the coastal area.Its major technique equipment be a tool keep afloat or sink to water-bed around and the bottom surface by the net cage of net composition, yet but exist with serious pollution disadvantage in the existing fish culture in net pen technology, because the place of employing fish culture in net pen is wind sheltering and the less place of current normally, in the process of fish culture in net pen, because (density of breeding fish is higher for remaining feed and fish excrement, fish excrement amount is very big) fall the bottom under net cage by the net cage spacer screen, thereby cause the pollution in waters, also can breed a large amount of planktons simultaneously, cause anoxic in the water, have a strong impact on the growth of fish, even also can cause " red tide ", cause the mortality of fish.

The purpose of this utility model just is to provide a kind of novel fish culture cage that prevents to pollute function that has, with by the mode of sewage collecting pocket is set in existing net cage bottom, residual feed and fish excrement that spacer screen by net cage is fallen down accumulate in this sewage collecting pocket, and eliminate above-mentioned pollution by the mode of periodical blowdown, reach in function of use that keeps prior art effectively and advantage, prevent the purpose of water pollution preferably.

The purpose of this utility model realizes in the following manner: a kind of have a novel fish culture cage that prevents to pollute function, the net cage that consists predominantly of by limit net, spacer screen, float that net cage keeps afloat and location hawser are formed, it is characterized in that being connected with sewage collecting pocket at net cage limit net and spacer screen connection, this sewage collecting pocket is bucket-shaped, and adopt comparatively fine and closely woven fibrous material to make, the bottom periphery of this sewage collecting pocket and net cage spacer screen form certain angle, its lowest part and spacer screen are apart from maximum, and its bottom periphery links to each other with net bottom limit, net cage limit.

Adopt the novel fish culture cage that prevents to pollute function that has of the present utility model, owing to adopted the mode that sewage collecting pocket is set in existing net cage bottom, thereby residual feed and fish fecal energy that the spacer screen by net cage is fallen down accumulate in this sewage collecting pocket, and eliminate above-mentioned pollutant by the mode of periodical blowdown, reach in function of use that keeps prior art effectively and advantage, prevent the purpose of water pollution preferably, improved the living environment of fish effectively, fish have been prevented because the death that water pollution caused, also have simple in structure simultaneously, be easy to make and advantage with low cost, overcome the deficiencies in the prior art preferably.

Description of drawings:

Fig. 1 is a kind of example structure schematic diagram of the present utility model;

Fig. 2 is an another kind of example structure schematic diagram of the present utility model.

Wherein: the 1-net cage, the 2-float, 3-limit net, the 4-spacer screen, 5-locatees hawser, 6-sewage collecting pocket, 7-blow-off pipe, the poly-dirty bucket of 8-.

Below in conjunction with drawings and Examples the utility model is further described.

As shown in the figure, a kind of novel fish culture cage that prevents to pollute function that has of the present utility model, the net cage 1 that consists predominantly of by limit net 3, spacer screen 4, float 2 that net cage keeps afloat and location hawser 5 are formed, it is characterized in that being connected with sewage collecting pocket 6 in net cage limit net 3 and spacer screen 4 connections, this sewage collecting pocket 6 is bucket-shaped, and adopt comparatively fine and closely woven fibrous material to make, the bottom periphery of this sewage collecting pocket 6 and net cage spacer screen 4 form certain angle, its lowest part and spacer screen 4 distances are maximum, and its bottom periphery links to each other with net 3 bases, net cage limit.In use, owing to be provided with sewage collecting pocket in the bottom of net cage, residual feed and fish fecal energy that the spacer screen by net cage is fallen down accumulate in this sewage collecting pocket, and the keeper can regularly get rid of above-mentioned pollutant by drip pump, reach antipollution purpose; In concrete manufacturing process, also can have same through hole at the lowest part of above-mentioned sewage collecting pocket 6, be connected with poly-dirty bucket 8 on it, bottom at poly-dirty bucket is provided with blow-off pipe 7, and the other end of this blow-off pipe is fixed on the float 2 of net cage 1 upper periphery, and the keeper advances blowdown by this pipe.
