However, at the same time, the flow and exchange of the water body are also hindered to a certain extent by the planting of the aquatic weeds, so that the traditional oxygenation device and means have the following technical defects:

(1) The volume of the air molecular groups (bubbles) formed by the oxygenation device is large, and the generated air molecular groups float out of the water surface at a high speed, so that the dissolved oxygen ratio of the water in the pool is too low, and most of oxygen is still discharged back to the air in a large bubble mode;

(2) The water body flows slowly, the oxygen increasing speed of local areas is high, so that an oxygen-rich area is generated, and oxygen in water cannot be diffused;

(3) At night, the aquatic weeds cannot be subjected to photosynthesis to produce oxygen, the plants need to be subjected to respiration during survival, and the water body flowing diffusivity in the aquatic weeds area is poorer, so that the situation of extreme underoxygen is formed in the aquatic weeds area, and the situation is worse if the aquatic weeds meet cloudy days;

(4) the dissolved oxygen level of the bottom water body is generally low, in addition, the activities of river crab life and other organisms and microorganisms are added, the oxygen consumption is large, but the dissolved oxygen improvement effect of the current oxygenation device on the bottom water body is small, and the dissolved oxygen improvement effect on the upper part of the water body is not obvious;

At present, the conventional pond culture oxygen increasing equipment has no equipment with excellent effect, high cost performance and convenient use. Thus, it is important to invent a device having the above-mentioned functions.

Detailed Description

reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.

Referring to fig. 1 to 8, the invention discloses a pond water-gas integrated auxiliary aquaculture device with microbubbles carried by water, which comprises a plurality of air supply mechanisms 10 arranged in a pond, wherein each air supply mechanism 10 comprises a self-suction pump set and a pipeline set connected to the self-suction pump set, the plurality of air supply mechanisms 10 are arranged in the pond, and after the oxygen-deficient water is extracted from the bottom of the pond through the self-suction pump combined pipeline set of the air supply mechanism 10, external air enters the water to be fully contacted, stirred and mixed, so that oxygen-enriched water carrying a large amount of micro bubbles is formed in the whole pond, the water quality of the pond is effectively improved, the inhabitation and growth of river crabs are facilitated, and the aquaculture effect of the river crabs is improved.

The self-priming pump set comprises a pump body 1, a thick bolt 2 and a thin bolt 4, a thick bolt micropore 7 is formed in an impeller negative pressure area of the pump body 1, the thick bolt 2 is in threaded fit in the thick bolt micropore 7, a micro hole 8 used for discharging air is formed in the surface of a nut of the thick bolt 2, the pipeline set comprises a water suction pipeline 5 and an outlet pipeline 6, the water suction pipeline 5 is connected to the water inlet end of the pump body 1, and the outlet pipeline 6 is connected to the water outlet end of the pump body 1.

under the water absorption of the pump body 1, the underoxygen water of pond bottom is taken out through water absorption pipeline 5, discharge through outlet conduit 6, simultaneously through the micro hole 8 on the nut surface of thick bolt 2 that is located negative pressure zone, make outside air can enter into inside the pump body 1, under the high-speed rotatory effect of the impeller of whole pump body 1 inside, make the air and the underoxygen water of entering inside the pump body 1 fully contact, stirring and mixing, thereby form the oxygen-enriched water that carries a large amount of micro bubbles, and the oxygen-enriched water of formation discharges the pond bottom again, increase the holistic dissolved oxygen volume in pond, effectively improve the condition of the regional underoxygen of pasture and water inside the pond, especially to the condition of night oxygen deficiency, effectively improve the breed effect of pond river crab.

the surface of the water outlet pipeline 6 is provided with a plurality of through holes 9, the adjacent through holes 9 have the same distance, and the water discharge diffusion effect of the water outlet pipeline 6 is improved by the through holes 9 in the water discharge process.

Further, under the action of the whole pump body 1, the formed oxygen-enriched water body carrying the micro-bubbles is sent into the water outlet pipeline 6 at a certain pressure and is discharged into the pond, and under the action of the pressure, the oxygen-enriched water body carrying the micro-bubbles forms micro-flowing water along the bottom of the pond in the waterweed area through the water outlet pipeline 6 and the through holes 9 on the surface of the water outlet pipeline; under the drive of the micro-flowing water, the oxygen-containing micro-bubbles diffuse from the bottom of the water grass area of the pond to the periphery and slowly rise, so that the river crabs can inhabit and grow, the diffusion effect is further improved, and the oxygen-enriched water is uniformly diffused in the pond.

And in the process that the oxygen-containing microbubbles rise from the upper surface layer of the bottom of the pond, the oxygen-containing microbubbles further contact with the water body, the contact surface of a large number of microbubbles and the water body is far larger than that of a large bubble and the water body, and the flow time of the microbubbles in water is relatively long, so that the oxygen dissolution rate is increased for the second time.
