The working principle of the unmanned aquaculture oxygenation workstation and the oxygenation method provided by the invention is as follows:
selecting a mounting point of an oxygenation workstation in an aquaculture pond in advance, building an annular support column matched with the oxygenation workstation on the mounting point, mounting the floating plate 1 on the support column through a plurality of pipe clamps, keeping the floating plate 1 to slide up and down along the annular support column, connecting a lead on the oxygenation workstation with a mains supply, starting a driving motor 23 and carrying out speed regulation through a gearbox 24 so as to enable an impeller 31 to stir water in the aquaculture pond, simultaneously driving gears 34 drive peripheral driven gears 36 to rotate, so that blades 37 below the driven gears 36 stir the water in the pond, air is mixed and contacted with the water, further the oxygen capacity of the water is further increased, the blades 37 have larger impact force on a water bottom layer when stirring the water in the pond, harmful gas on the water bottom layer escapes from the water surface, and the bottom layer water with high content of bottom organic matters and harmful substances is lifted to an upper layer oxygen enrichment area, make organic matter and harmful substance obtain abundant oxidative decomposition, reduce the oxygen consumption at night, reduce the harmful substance content, improve the bottom matter, when needing to carry out oxygenation to the pond water of deep water layer, open the oxygen pump in the floating bucket 42, make the oxygen in the floating bucket 42 discharge to the pond water through the exhaust duckbill 46, each exhaust duckbill 46 output is equipartition all around, and the oxygen that exhaust duckbill 46 discharges cooperates blade 37, the dissolved oxygen level of breed pond has been improved, and the exhaust duckbill 46 clockwise direction of mounting panel 45 bottom, cooperate the effect of the stirring pond water of blade 37, make the surface layer water body carry out oxygenation in a large scale, simultaneously to middle level, bottom water body oxygenation and get rid of a large amount of microorganisms in the water body still can make the harmful substance of bottom layer go up to the oxygen-rich region in upper strata, make organic matter and harmful substance obtain abundant oxidative decomposition, and when oxygen is sufficient in the floating bucket 42, the whole buoyancy of floating bucket 42 is great, the oxygen increasing mechanism 3 is enabled to be deviated to the water surface, after a certain amount of oxygen is used in the floating barrel 42, the oxygen increasing mechanism 3 descends one section to the pool water, so that the oxygen increasing effect is further enhanced for the middle-layer water body and the bottom-layer water body, the ozone generator 5 and the through openings connected with the ozone generator 5 through the three-way valve 47 are opened, the ozone is sprayed out from the outlet of the hose, a large amount of microorganisms in the aquaculture water are killed, and the dissolved oxygen amount in the water body is prevented from being reduced.
The invention is used for the oxygenation workstation of the fishpond and the test experiment of the prior art;
the experimental steps are as follows: firstly, selecting two fishponds with the same area and structure, wherein aquaculture water in the two fishponds is changed in one day before the experiment, the changed water amount is the same, sampling water in the middle surface layer, the middle layer and the bottom layer of the fishponds in two days of the test, detecting the oxygen capacity of the sampled water by using a special oxygen content measuring tool, digitally recording the detected water, finally respectively placing the oxygen increasing workstation and the oxygen increasing workstation in the prior art into the two fishponds, stopping two groups of oxygen increasing workstations after running for 60 minutes, sampling water in the middle surface layer and the bottom layer of the oxygenated aquaculture water, detecting the oxygenated water by using the special oxygen content measuring tool, and recording the detected result for analysis.
And (3) analyzing an experimental result: as can be seen from the attached drawings 5 and 6, the oxygen-increasing workstation of the invention can obviously improve the oxygen content of the aquaculture water, and the oxygen dissolution amounts of the surface layer, the middle layer and the bottom layer of the aquaculture water after oxygen increasing are not greatly different, while the oxygen-increasing workstation of the prior art only slightly improves the oxygen dissolution amount of the aquaculture water after oxygen increasing of the aquaculture water, and the comparison shows that the oxygen-increasing workstation of the invention is superior to the prior art.
