Abstract

A semi-closed flow-control fish-farming ship for river and flowing water area is composed of two bow-shaped floating boxes and a semi-closed fish-farming cabin connected between them via steel frame, and the semi-closed fish-farming cabin is mainly formed by steel frame, steel plate and steel plate net. Therefore, the feed can be greatly saved, and the fish culture cost is reduced. And a relatively stable living environment for the fishes in the rivers is created, and the disease prevention effect is favorably improved. The semi-closed flow-control fish culture boat is an ideal device for intensive fish culture in rivers and flowing water areas.

Description

Semi-closed running water control fish culturing ship on river and running water zone

The utility model relates to a kind of rivers and the novel fish culture apparatus of the interior water velocity of the controlled well in waters that flows.

At present, domesticly utilizing fluctuation obvious, the rivers exploitation fish culture in net pen that change in flow is big does not have mature technology as yet, and its one of the main reasons is exactly the fish culture apparatus that does not adapt to it, once there was the people to breed fish at the mid-ship of rivers, but be placed in the river because net cage is naked, river flows and forces fish to be in motion state against the current for a long time, causes very big fish physical efficiency consumption, feed consumption is increased considerably, even the too tired dead phenomenon of fish appears, the bait throwing in turnover rate also increases simultaneously, has a strong impact on culture benefit.

The purpose of this utility model is to provide a kind of semiclosed control stream of the normal rivers of culturing of fish and the waters of flowing fish culturing ship that all can satisfy under the state of different water speed.

The purpose of this utility model is achieved in that to be that this semiclosed control stream fish culturing ship is formed by two fore type buoyancy tanks with by the semi-enclosed well that steelframe is connected in it therebetween.

Semi-enclosed well is made up of steelframe, steel plate, expanded metal lath.

Advantage of the present utility model is to reduce the water velocity in the well, and makes well obtaining suitable water exchange capacity on the river surface of different in flow rate or when summer, the river fluctuation was frequent at any time, for a stable relatively environment has been created in fish culture.Can keep the interior water quality of well pure and fresh, fish moves about less, reduces beverage cost, makes fish look fertile again, and is dead few, the culture benefit height.

The concrete structure of the semiclosed control stream of the utility model fish culturing ship is drawn by the following drawings:

Fig. 1 is one of embodiment of the semiclosed control stream of the utility model fish culturing ship, this embodiment is the citation form of this ship, it is characterized in that fish culturing ship forms by two fore type buoyancy tanks with by the well that steelframe is connected in it therebetween, well is made up of the expanded metal lath of steelframe, steel plate and bottom, side.

In the drawings, 1 is fore type buoyancy tank, and 2 are the exchange network of rivers, side window, and 3 is well, and 4 is railing, and 5 are bottom surface exchange blowdown net window, and 6 are the work canopy.

Fig. 2 be the semiclosed control of the utility model stream fish culturing ship embodiment two, this embodiment has set up the exchange network of rivers, side window lid (inserting) plate 7 on the basis of first embodiment, to slow down the flow velocity in the out-of-date fast well of river waterflow, to increase its scope of application.

Fig. 3 be the semiclosed control of the utility model stream fish culturing ship embodiment three.This embodiment is characterised in that on the basis of first embodiment, forwardly have additional controlled water inlet pipe (canal) on the fore type buoyancy tank, to replace the effect of side water switching network window, can regulate water exchange velocity in the well by controlled water inlet pipe (canal), be adapted to the stable waters of current direction, can alleviate silt harm and raising and prevent and treat the fish disease effect.

8 is water inlet pipe (canal) slag net in the drawings, and 9 are control stream lock, and 10 is water inlet pipe (canal) net window, and 11 is water inlet pipe (canal) road.

Fig. 4 be the semiclosed control of the utility model stream fish culturing ship embodiment four, this embodiment collects the great achievement of first three embodiment, promptly on the basis of first embodiment, set up the exchange network of rivers, side window lid (inserting) plate 7, forwardly set up controlled water inlet pipe (canal) on the fore type buoyancy tank, thereby having strengthened the adjusting function of well water, is the more complete form of this utility model, makes the applicability of fish culturing ship more extensive.

Claims

1, the semiclosed control stream in a kind of rivers and the waters of flowing fish culturing ship is characterized in that two fore type buoyancy tanks and forms by the semi-enclosed well that steelframe is connected in it therebetween.

2, semiclosed control stream fish culturing ship as claimed in claim 1 is characterized in that semi-enclosed well is made up of steelframe, steel plate, expanded metal lath.
