Description

Seizing cage tool
Technical field
The utility model relates to Ecology engineering, particularly relates to a kind of seizing cage tool.
Background technology
The Water Ecological Recovery engineering later stage is by throwing in the bio-diversity of the recovery water bodys such as appropriate fishes and shrimps, hydrobiological growth, the further purification of water quality can be promoted, particularly filter-feeding fish can remove the algae substances in water body effectively, but along with the growth of submerged plant and the improvement of water quality, fish and shrimp population quantity increases to be accelerated, too much fishes and shrimps, particularly herbivorous fishes, by submerged plant blade of excessively searching for food, cause adverse effect to the stable of structure of community in aquatic ecosystem.Therefore, the later maintenance of aquatic ecosystem must control the carrying out of fish and shrimp population quantity and adjust.
Traditional fishes and shrimps catching net, volume is comparatively large, and catching rate is lower, is layed in the bottom, easily damages pasture and water.And, aquatic ecosystem take pasture and water as core, variety classes aquatic animal is distributed in different water levels, as shrimps inhabit lower floor in water body, fish inhabit upper, middle lower floor in water body respectively according to different ecological habit, and tradition is fished for layup tool and is located at the bottom, is difficult to fish for the fish of water body at the middle and upper levels, easily cause pelagic fishes quantity too much, cause species unbalance.
Summary of the invention
Based on this, be necessary for the problems referred to above, a kind of seizing cage tool is provided.Adopt this seizing cage tool, effectively can control the density of water body different water levels fishes and shrimps, and less on water-bed pasture and water impact, be conducive to the species balance safeguarding aquatic ecosystem.
A kind of seizing cage tool, comprising:
Support, comprises cage body and leg, and described cage body forms tower structure, and described leg is located at below cage body;
Cage net, comprise outer etting and internal layer etting, described outer etting is coated on cage body framework, and cage body inner space is divided at least two catchers by vertical direction arrangement by described internal layer etting, and each catcher is equipped with the entrance be communicated with space outerpace; And
Floatage body, this floatage body is connected with support.
Above-mentioned seizing cage tool, after input is to water, floatage body is bubbled through the water column, and cage tool naturally droops, and light seat is in water body, and whole cage tool can support by its leg, and is not exclusively layed in the bottom, avoids the damage to pasture and water.And pass through the design of internal layer etting, space in cage body is set to the catcher separated up and down, traps different water levels aquatic animal respectively, the separately picking of dissimilar fishes and shrimps when being convenient to track down and recover.The more important thing is can be balanced fish for the fish and shrimp inhabiting water body different layers, keep water body species balance.
Wherein in an embodiment, described internal layer etting forms the narrow structure of the wide inside opening of outside opening in porch.This design can prevent from being returned by the fishes and shrimps entering catcher exiting.
Wherein in an embodiment, be also provided with separator in described cage body, described internal layer etting, under the support of separator, forms the netted passage with corner in catcher.Further add the difficulty that fishes and shrimps exit in catcher.
Wherein in an embodiment, according to the direction that netted passage ecto-entad is deep, described internal layer etting forms the narrow structure of the wide inside opening of outside opening in the position of netted channel corner.By this structure, fishes and shrimps can be impelled deeply to move about along passage ecto-entad, avoid it oppositely to move about and exit catcher.
Wherein in an embodiment, described each catcher is equipped with a folding and unfolding mouth opened or close formed by cage net.When throwing in this cage tool and entering water body, folding and unfolding mouth is in the state of tightening up always, opens and collect fishes and shrimps when tracking down and recovering.
Wherein in an embodiment, described leg also overlaps the buttress cover having anti-slip material to make.Strengthen frictional force when contacting with Sediments, play the effect of fixing cage tool further, avoid it to rock with current in water body, fishes and shrimps dare not be entered.
Wherein in an embodiment, this seizing cage tool also comprise gain in weight for this seizing cage tool increase the weight of pendant, described in increase the weight of pendant and be located on leg.This increases the weight of to fall can be the larger object of iron chains isodensity, makes cage tool have certain heavy power, and light seat that can be more stable is in water body, and the quantity of iron chains sinks force rate setting according to different water depth buoyancy.
Wherein in an embodiment, described cradle top is provided with the handle for lifting.Cage tool is mentioned when being convenient to track down and recover.
Wherein in an embodiment, described floatage body is connected with cradle top by stay cord, and the length of described stay cord is 30-70cm, preferred 50cm.
Wherein in an embodiment, described support is folding bracket.There is folding and unfolding advantage easily.
Compared with prior art, the present invention has following beneficial effect:
A kind of seizing cage tool of the present utility model, can multiple spot dispersion be invested in water, by the floatage body of upper end and the leg of lower end, cage tool is made comparatively stably vertically to be placed in water, and can not crushing to bottom pasture and water, by the design of cage net, make this cage tool have the different layers catcher of arranging up and down, effectively can trap the fish and shrimp of different water levels in water body, contribute to keeping water body species balance.
Further, this seizing cage tool also by cage net design cleverly, forms the netted passage with corner, and the situation that can well prevent fishes and shrimps from escaping occurs.
It is simple that this seizing cage tool has structure, makes easily, to water plants and the less feature of animal injury, therefore, for the aquatic ecosystem later stage aquatic animal quantity regulating taking pasture and water as core, has stronger practicality and promotional value.
