[0013] Beneficial Effects

[0014] Compared with the prior art, the oxygenation device for shrimp factory farming of the utility model has the following advantages:

[0015] 1. In addition to oxygenation through the oxygenation pump, the motor can be started to drive the rotating shaft to rotate, so that several stirring blades can stir the pond water, so that the oxygen can be fully mixed with the water body, and the dissolved oxygen in the water can be increased. In addition, the water pump can be started to suck the pond water through the water pipe, and spray it into the air along the water pipe and the nozzle, so that the water is dispersed in the atmosphere, which greatly increases the specific surface area of ​​the water, making it easier for the water to dissolve oxygen in the air, thereby making the oxygenation effect more efficient.

[0016] 2. A counterweight cylinder is provided at the bottom of the floating plate. The cylinder cover can be opened by rotating, and counterweight blocks can be added or removed from the cylinder. After completion, the cylinder cover can be closed. The top plate will press against the counterweight block under the action of the spring force to prevent the counterweight block from sliding and causing an unstable center of gravity. The water level at the aeration point can be adjusted by adding or removing the counterweight block to make the floating plate sink or rise accordingly.

[0017] 3. The scale makes it easy to understand the sinking degree of the float.

[0018] 4. A filter is fitted at the bottom of the water pump, which can filter impurities in the water to prevent damage to the water pump.

[0019] 5. The slide groove of the counterweight cylinder guides and limits the movement of the top plate slider.

The output end of the motor 6 is fixedly connected to a rotating shaft 7, and the bottom end of the rotating shaft 7 passes through the bottom end of the floating plate 1 and is fixedly connected to a plurality of stirring blades 8, and the mixing of oxygen and water can be improved by the rotation of the stirring blades 8.

[0029] When in use, the device floats on the surface of the shrimp pond through the floating plate 1, presses air into the water through the oxygenation pump 3, and discharges it into the water from a plurality of aeration holes 5, so that the oxygen in the air is fully in contact with the water, so as to allow part of the oxygen to be integrated into the water and increase the oxygen content of the water. In addition, by starting the motor 6 to drive the rotating shaft 7 to rotate, the plurality of stirring blades 8 can stir the pond water, so that the oxygen can be fully mixed with the water body, and the dissolved oxygen in the water is increased. The water pump 2 can also be started to suck the pond water through the water pump 18, and spray it into the air along the water pipe 20 and the nozzle 21, so that the water is dispersed in the atmosphere, which greatly increases the specific surface area of ​​the water and makes it easier for the water to dissolve the oxygen in the air, thereby making the oxygenation effect more efficient.
