1 to 3, the apparatus for increasing the concentration of dissolved oxygen in the aquarium of the present invention includes a hull 110, a fluid flow pipe 130, an air inlet pipe 140, a pump 150, and a control unit 170 .

The hull 110 may be floated on the aquaculture farm 10 and may be formed in a conventional vessel form.

The fluid circulating pipe 130 is connected to the outside of the hull 110 along the longitudinal direction of the hull 110 to the portion of the hull which is submerged below the water surface of the hull so that the propulsion force of the hull 110 can be generated by the circulation of the aqua- And the inner diameter of the center portion 134 is formed to be smaller than the inner diameter of the extended portion extending to the outside of the hull 110 out of the central portion 134. [

The first inlet 131a is exposed to the outside of the hull 110 at one side of the hull 110 and extends to the center portion 134 and has an inner diameter larger than the inner diameter of the central portion 134, A second outlet 132a is provided on the other side of the hull 110 which is submerged below the water surface so as to be exposed to the outside of the hull 110 and extends to the center portion 134 And has a second flow tube portion 132.

2 and 3, the first entrance 131a or the second entrance 132a may be configured to generate a swinging force capable of turning the hull 110 when the aquaculture water 20 flows in or out. And is formed by cutting the opening surface slanting in the vertical direction with respect to the longitudinal direction of the hull 110.

In the illustrated example, both the first entrance 131a and the second entrance 132a are formed to be inclined. However, unlike the illustrated example, only one of the first entrance 131a and the second entrance 132a can be inclined Of course it is.

In this case, a swirling force is generated in the hull 110 due to the flow velocity difference in the cross-sectional direction of the opening surface due to the inclined structure when the water enters through the first entrance 131a or the second entrance 132a.

On the other hand, another example for inducing the turning force of the hull 110 is shown in Fig.

Referring to FIG. 4, the turning guide portion for guiding the turning force of the hull 110 includes a direction adjusting key 211, a spring 213, a flow cap 215, and a connecting line 217.

The direction adjusting key 211 is provided with a direction adjusting body 211a capable of adjusting the direction of the hull 110 to be rotatable through the hinge 211c on the hull 110, And an adjusting bar 211b integral with the direction adjusting body 211a is extended on the side opposite to the direction adjusting body 211a.

One end of the spring 213 is fixed in the fluid flow pipe 130 whose length is elastically variable by an external force, and the other end is coupled to the flow cap 215.

The fluid cap 215 is connected at one end to the other end of the spring 213 and at the other end to the connection line 217 to interfere with the fluid flow in the fluid flow pipe 130, do.

The flow cap 215 is formed in a structure having a concave space in a hemispherical shape so as to widen the contact area of the fluid, and a plurality of through holes 215a are formed so that the fluid can pass therethrough.

The connecting line 217 is interlocked with the flow of the flow cap 215 and is coupled between the flow cap 215 and the direction adjusting key 211 so that the direction adjusting key 211 is rotated in the direction in which the hull 110 is turned .

The connecting line 217 may be coupled to the direction adjusting key 211 so that the fluid does not flow through the fluid flow pipe 130 in a state where the direction adjusting key 211 is positioned in a direction parallel to the extending direction of the hull 110, .

Reference numeral 220 denotes a net for allowing the flow cap 215 to flow only in one direction and inducing dispersion of the fluid.

When the flow cap 215 is moved away from the net 220 as the fluid flows through the fluid flow pipe 130, the connection guide 217 is pulled in the direction of the spring 213, So that the turning force can be induced.

The spring 213 functions to return the flow cap 215 to its initial position when the flow of the fluid stops.
