Detailed Description
In the description of the present invention, it should be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
The utility model will be further explained with reference to the drawings.
As shown in fig. 1-4, the new water injection system for the large-scale fish culture tank provided by the utility model comprises water injection pipes 4 arranged at four corners of the culture water tank, and a partition wall between each water injection pipe and the culture water tank forms an angle of 135 degrees with the inner wall of the culture water tank; the lower part of the water injection pipe is communicated with the seawater through a seawater main pipe 3, and a seawater pump 1 and an oxygenation unit 2 are arranged on the seawater main pipe. Along the flowing direction of seawater, the oxygenation unit is positioned behind the seawater pump.
The lateral wall of the water injection pipe is provided with more than 10 honeycomb ducts 5 communicated with the culture water cabin, and the length of the honeycomb ducts is more than 600 mm. The honeycomb duct is located the water injection pipe inside, and opening edge fixed connection is in water injection pipe inner wall to become level 30 degrees in water injection pipe inner wall, the play water direction forms syntropy's circulation form. The other end opening of the flow guide pipe is provided with a blocking net 6.
The separation net is fastened at the opening of the draft tube through a flange. The net holes 7 are uniformly distributed on the blocking net, and the diameter range of the net holes is 25-40 mm, so that the flow cross section is ensured, and the blocking effect is achieved. The separation net prevents fish from reversely entering the water injection pipe from the guide pipe and can prevent foreign matters from entering the culture water tank.
During use, external seawater enters the seawater main pipe through the seawater pump, the oxygen increasing unit extracts a part of seawater from the seawater main pipe for saturation oxygen increasing, the seawater coming out of the oxygen increasing unit is rich in oxygen and then returns to the seawater main pipe, and therefore the seawater in the seawater main pipe becomes oxygen-enriched seawater and then enters the water injection pipe.
After the oxygen-enriched seawater in the seawater main pipe enters the water injection pipe, the oxygen-enriched seawater enters the aquaculture water tank from the diversion pipe, and the oxygen-enriched seawater enters the aquaculture water tank along a fixed direction under the action of the diversion pipe due to a certain included angle between the diversion pipe and the inner wall of the aquaculture water tank, so that water flow in a stable direction is formed in the aquaculture water tank, and the flow of water flow in a simulated natural state is realized; and because a plurality of (at least 40) honeycomb ducts are arranged, a plurality of oxygen-enriched seawater inlets can be formed in the culture water cabin, and the flow velocity of seawater can be effectively reduced, thereby creating favorable conditions for the formation of the whole oxygen-enriched environment in the culture water cabin and the low flow velocity. The honeycomb duct installation need form certain angle with breed water tank inner wall, and with the inner wall parallel and level, avoid causing the injury to the fish in breeding the water tank.
It should be understood that the above description is only a preferred embodiment of the present invention, and not intended to limit the present invention, and although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and equivalents may be made in the technical solutions described in the foregoing embodiments, or some technical features may be substituted. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
