[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] like Figure 1-Figure 5 As shown, a river ecological restoration device includes a submersible pump 1, an ejector 2 is provided on one side of the submersible pump 1, a diffuser 3 is provided on one side of the ejector 2, a float 4 is provided on the outside of the submersible pump 1, and a drive assembly is provided on the upper side of the float 4. The drive assembly includes a motor 8, which is embedded in the upper side of the float 4, and a gear 1 9 is provided on the shaft end of the motor 8. One side of the gear 1 9 is meshed with a gear 2 10, and the gear 2 10 is rotatably sleeved on the outside of the ejector 2. One side of the gear 2 10 is meshed with a plurality of gear 3 11, and one side of the gear 3 11 is meshed with an inner gear ring 12, which is rotatably connected to the upper side of the float 4, and the outer side of the inner gear ring 12 is connected to one side of the scraper 13.

[0026] A filter frame 7 is provided on the lower side of the float 4, a scraper bar 13 is provided on one side of the drive assembly, a number of floats 5 are provided on the outside of the float 4, a baffle 6 is provided on the upper side of the float 4, the baffle 6 is placed on the lower side of the diffuser 3, a connecting rod 14 is provided on the lower side of the gear three 11, a number of stirring blades 15 are provided on the outer bottom of the connecting rod 14, a solar photovoltaic ring 16 is embedded on the upper side of the baffle 6, and a battery 17 is embedded on the upper side of the float 4.

[0027] In this embodiment, the submersible pump 1 is working, extracting liquid and sending it to the ejector 2, and then sending it to the diffuser 3 for spraying through the ejector 2. During use, the filter frame 7 is used to block the filtrate, and the motor 8 drives the gear 1 9 to rotate. The gear 1 9 rotates to engage the transmission gear 2 10, and the gear 2 10 engages the transmission gear 3 11. The gear 3 11 then engages the transmission inner gear ring 12. The inner gear ring 12 drives the scraper 13 to rotate, and the scraper 13 scrapes the filter frame 7. The baffle 6 is used to block the liquid sprayed by the fountain to prevent the liquid from spilling onto the drive assembly. The rotation of the gear 3 drives the connecting rod 14 to rotate, and the connecting rod 14 drives the stirring blade 15 to stir. The stirring blade 15 stirs the river water and sludge to make it turbid.

[0028] It should be noted that a suction pipe and hose are installed on one side of the submersible pump 1. The submersible pump 1, ejector 2, diffuser 3, suction pipe, and hose form an aerator. During operation, the pump impeller, driven by the submersible motor, rotates at high speed, pushing the mud-water mixture into the ejector to form a jet. This creates a negative pressure zone around the jet, and air is drawn into the negative pressure zone of the jet nozzle through the suction pipe. The air, water, and mud are thoroughly mixed in the ejector's throat. The jet's kinetic energy is then gradually converted into pressure energy through the ejector's diffuser before entering the diffuser. Within the diffuser, the air, water, and mud mixture further mixes, forcing the gas to continue shearing, pulverizing, and emulsifying, ensuring that most of the oxygen is fully dissolved in the water. At the same time, under the action of the jet fluid pressure, the jet carries oxygen molecules and tiny bubbles, which are sprayed downward from the nozzle of the diffuser and diffused, forming an impact and stirring on the water body and the sludge at the bottom of the biochemical pool, and then slowly rise from the bottom of the pool to the water surface. The microbubbles generally stay in the water for more than 30 seconds, so that the oxygen in the air is fully dissolved and absorbed, thereby improving the oxygen transfer efficiency and oxygenation capacity.

[0029] This equipment can generate high negative pressure and strong turbulence, stirring and shearing between muddy water and air in the ejector, which promotes high-frequency oscillation of liquid film and gas film, greatly reduces the diameter of bubbles, increases the number of bubbles, and increases the specific surface area of ​​bubbles. At the same time, it also makes the gas-liquid film thinner, which can greatly reduce the mass transfer resistance and make oxygen molecules transfer better from gas phase to liquid phase.

[0030] When the jet moves forward at high speed, it has a high angular velocity under the action of high-speed rotation in the disperser, which makes the jet have strong penetrating power, makes the tiny bubbles travel far in the water, and enhances the stirring, pushing and oxygenation capabilities.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
