Abstract
The utility model discloses a fish is with hatching box with a net, box with a net body including the top end opening, the bottom surface upper berth of box with a net body is equipped with stainless steel fixture, all be equipped with horizontal frenulum on two sides of the left and right sides of box with a net body, still include the stay cord and the fixed pulley of a plurality of adjustment box with a net body height, the quantity of stay cord and one -to -one the same with the quantity of fixed pulley, the end of stay cord is equipped with the clip, the clip clamp is on the box with a net body, the other one end of stay cord twine on the fixed pulley and stretch out with the fixed pulley outside. The beneficial effects of the utility model are that: (1 ) simple structure, (2 )Can improve the incubation rate of growing seedlings greatly, (3 )Conveniently emerge.
Description
Technical field
The utility model relates to a kind of net cage, particularly a kind of fish incubation net cage.
Background technology
At present, conventional Fish hatcheries facility has the large-scale hatchery facility such as circular hatching channal, hatching pail, incubation tank, hatching pail and incubation tank are all utilize water impact that fish-egg is not precipitated, but this principle can make seedling easily be subject to wound when membrane just, greatly reduce survival rate, circular hatching channal aborning circuit inside bend place easily causes fish-egg to be piled up, and thus also can affect incubation rate.
Summary of the invention
Problem to be solved in the utility model is: provide the fish incubation net cage that a kind of structure is simple, incubation rate is high.
In order to solve the problem, fish incubation net cage of the present utility model, comprise the net cage body of top end opening, the bottom surface of described net cage body is equipped with stainless steel stent, the side, two, left and right of described net cage body is equipped with horizontal frenulum, also comprise stay cord and the fixed pulley of some adjustment net cage body height, the quantity of described stay cord and one_to_one corresponding identical with the quantity of fixed pulley, the end of described stay cord is provided with clip, described clip is sandwiched on net cage body, the other one ends wound of described stay cord on fixed pulley and stretch out with fixed pulley outside.
Further, fish incubation net cage of the present utility model, length, the width of described net cage body and be highly respectively 3000mm, 700mm and 400mm.
Further, fish incubation net cage of the present utility model, described net cage body is that 80 object polythene nets are made and formed by order number.
Further, fish incubation net cage of the present utility model, the stainless steel rebar that described stainless steel stent is 6mm by diameter supports.
The beneficial effect that the utility model obtains is: (1) structure is simple, (2) when concrete use, net cage body is positioned in hatchery, by horizontal frenulum, net cage body is fixed in hatchery, fixed pulley is fixed on the ceiling above hatchery, the end of stay cord is sandwiched on net cage body by clip, the other one ends wound of stay cord is on fixed pulley and stretch out from fixed pulley and be fixed on wall, so, whole net cage body is just suspended in hatchery, when hatching, fish-egg is laid on the bottom surface of net cage body, put because net cage body is outstanding, fish-egg periphery is ventilated, thus significantly reduce the generation of saprolegniasis, water in hatchery remains static, thus Lentic hatching turn avoid water impact to just wanting the seedling of membrane to cause wound, regulate the height of stay cord, i.e. the volume of water body in adjustable cage body, conveniently to produce, thus greatly can improve the incubation rate of nursery, (3) when fry hatching successfully turns the pool, untie horizontal frenulum, pull stay cord to be mentioned by net cage body, thus greatly facilitate and emerge.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, net cage body, 2, stainless steel stent, 3, horizontal frenulum, 4, stay cord, 5, fixed pulley, 6, clip.
Embodiment
As shown in Figure 1, fish incubation net cage of the present utility model, comprise the net cage body 1 of top end opening, the bottom surface of described net cage body 1 is equipped with stainless steel stent 2, the side, two, left and right of described net cage body 1 is equipped with horizontal frenulum 3, also comprise stay cord 4 and the fixed pulley 5 of some adjustment net cage body 1 height, the quantity of described stay cord 4 and one_to_one corresponding identical with the quantity of fixed pulley 5, the end of described stay cord 4 is provided with clip 6, described clip 6 is sandwiched on net cage body 1, the other one ends wound of described stay cord 4 on fixed pulley 5 and stretch out with fixed pulley 5 outside; Length, the width of described net cage body 1 and be highly respectively 3000mm, 700mm and 400mm; Described net cage body 1 is that 80 object polythene nets are made and formed by order number; The stainless steel rebar that described stainless steel stent 2 is 6mm by diameter supports.
Fish incubation net cage of the present utility model, structure is simple, when concrete use, net cage body 1 is positioned in hatchery, by horizontal frenulum 3, net cage body 1 is fixed in hatchery, fixed pulley 5 is fixed on the ceiling above hatchery, the end of stay cord 4 is sandwiched on net cage body 1 by clip 6, the other one ends wound of stay cord 4 is on fixed pulley 5 and stretch out from fixed pulley 5 and be fixed on wall, so, whole net cage body 1 is just suspended in hatchery, when hatching, fish-egg is laid on the bottom surface of net cage body 1, put because net cage body 1 is outstanding, fish-egg periphery is ventilated, thus significantly reduce the generation of saprolegniasis, water in hatchery remains static, thus Lentic hatching turn avoid water impact to just wanting the seedling of membrane to cause wound, regulate the height of stay cord 4, i.e. the volume of water body in adjustable cage body 1, conveniently to produce, thus greatly can improve the incubation rate of nursery.
When fry hatching successfully turns the pool, untie horizontal frenulum 3, pull stay cord to be mentioned by net cage body, thus greatly facilitate and emerge.
