Different restoration technologies can complement each other, and selecting the appropriate one can effectively improve water conditions. During water environment restoration, aeration and oxygenation are necessary to repair black and odorous water bodies and the aquatic ecosystem.

[0003] Chinese patent application publication number CN115231693A discloses an aeration and oxygenation ecological restoration system comprising a plurality of vertically staggered concave trays and convex trays. The convex trays have through-holes in the middle, and fillers are provided on the concave trays and convex trays. The concave trays and convex trays are located above the aeration device.

[0015] Beneficial effects of the present invention:

[0016] 1. In the present invention, when water flows or aeration generates flow, the turbine can be forced to rotate and drive the inner gear ring to rotate. The rotation of the gear ring can drive the multiple meshing driven gears on the inner side to rotate. The rotation of the driven gear can drive the rotating shaft located on the inner side to rotate. The rotation of the rotating shaft can drive the outer turbulence component to rotate and cut the inner aeration bubbles and drive the other side wheel body and the rotating shaft located outside the outer filter membrane to rotate through the top transmission belt. The rotation of the rotating shaft can drive the external outer blades to rotate, and the turbine is driven by the water to flow by itself to achieve turbulent mixing between water bodies at different depths. By increasing turbulent disturbance, the turbulence degree of the water body is increased during aeration, thereby increasing the contact time with aeration and improving the aeration efficiency. The rotating turbulence component and the outer blades increase the contact area between the aeration bubbles and the water body, extend the flow time of the bubbles, and improve the diffusion efficiency of the solution oxygen.

[0017] 2. In the present invention, the outer protrusion is driven to rotate by the rotation of the turntable, and the rotation of the protrusion can squeeze the inclined surface of one side of the triangular plate. The movement of the triangular plate drives the movement of the inner movable rod, and the movement of the movable rod can drive the transmission rod to push the hinged position of the bottom side of the aeration nozzle. At this time, the aeration nozzle can be rotated and sleeved on the aeration direction of the top through the middle hinged rod. Through the multiple groups of aeration nozzles arranged circumferentially, the airflow dispersion range during aeration is controlled, which is conducive to adapting to different water flow conditions and the tangent direction of the water flow after the device is installed, thereby improving the aeration treatment efficiency. The rotatable turntable can adapt to the changes in the water flow to adjust the aeration angle, which is conducive to improving the aeration treatment efficiency and the contact area with the water flow, thereby improving the aeration efficiency and avoiding the need for the lateral flow velocity of the water body to increase the solution oxygen content of the surrounding water body due to vertical upward flow.

[0018] 3. In the present invention, the rotating shaft can drive the external turbulence disk to rotate. When the turbulence disk rotates around the rotating shaft, it can tilt and disturb the water body. The tilted turbulence disk can improve the full separation of the aeration bubbles and guide the bubbles to generate turbulence. The air holes can disturb the bubbles when the aeration bubbles pass through, which is beneficial to improving the aeration contact effect. At the same time, when the output shaft of the driving motor rotates, it can drive the reciprocating screw to rotate. The rotation of the reciprocating screw can drive the external screw seat to drive the turbulence rotor to move up and down. The reciprocating turbulence rotor and the spiral blades can drive the water in the water body to move in the axial space, which is beneficial to improve the full circulation and mixing of the water in the water body in the axial space. It solves the technical problems of traditional aeration equipment having a small aeration range and a small contact range with the water, which is restricted by the water environment.

[0033] An aeration control mechanism 5 is provided on the bottom side of the inner cavity of the outer filter membrane 2. The aeration control mechanism 5 includes a plurality of aeration nozzles 504 with adjustable aeration angles, which are used to adjust the aeration angle through the aeration nozzles 504. An inner treatment membrane 3 is installed in the outer filter membrane 2. A flow disturbance drum 7 is rotatably connected to the inner cavity of the inner treatment membrane 3. The flow disturbance drum 7 is externally connected to a spiral blade 10, which is used to disturb the water body through the rotation of the spiral blade 10.

[0034] Specifically, the aeration mechanism in this embodiment can be a plurality of aeration units arranged in an array at a certain angle in the water body, or can be independently set in the water body for aeration circulation, thereby increasing the fluidity of the water body and enhancing the mass transfer effect, and increasing the dissolved oxygen concentration in the water body to facilitate the growth and reproduction of aerobic microorganisms.

[0035] See also Figure 3-5The disturbance component 4 includes multiple groups of radially opposite rotating shafts 401, and the two radially opposite rotating shafts 401 are respectively located on the inner and outer sides of the outer filter membrane 2, and the two radially opposite rotating shafts 401 are connected by a transmission belt 403 through a driving wheel transmission, and the top of the rotating shaft 401 located on the outer side is connected to one side of the cover plate 14 through a bearing seat, and the outer side of the rotating shaft 401 located on the outer side of the outer filter membrane 2 is connected to the outer blade 402, and the other rotating shaft 401 located on the inner side of the outer filter membrane 2 is relatively connected to the axis of the turbulence component 8, and the bottom end of the rotating shaft 401 located on the inner side of the outer filter membrane 2 is connected to a driven gear 404, and a gear ring 405 is meshed between multiple groups of driven gears 404, and the gear ring 405 is connected to the top of the turbine 1, which is used to drive the outer blades 402 and the turbulence component 8 to rotate around the rotating shaft 401 through the rotation of the turbine 1 to disturb the water body.

[0036] The rotating shaft 401 located on the inner side of the outer filter membrane can be connected to the inner wall of the outer filter membrane 2 through a bearing seat to ensure the stable rotation of the rotating shaft 401;

[0037] Specifically: In order to avoid the low water flow rate affecting the aeration mass transfer effect, through the designed turbulence component 4, when the water flows or the aeration generates flow, the turbine 1 can be forced to rotate and drive the inner gear ring 405 to rotate, the rotation of the gear ring 405 can drive the multiple driven gears 404 engaged on the inner side to rotate, the rotation of the driven gear 404 can drive the rotating shaft 401 located on the inner side to rotate, the rotation of the rotating shaft 401 can drive the outer turbulence component 8 to rotate and cut the inner aeration bubbles and drive the other side wheel through the top transmission belt 403 The body and the rotating shaft 401 located outside the outer filter membrane 2 rotate. The rotation of the rotating shaft 401 can drive the external outer blades 402 to rotate, thereby driving the turbine 1 to flow by the water body to achieve turbulent mixing between water bodies at different depths. By increasing the turbulent disturbance, it is beneficial to increase the turbulence level of the water body during aeration, thereby increasing the contact time with the aeration and improving the aeration efficiency. The rotating turbulent flow component 8 and the outer blades 402 increase the contact area between the aeration bubbles and the water body and extend the flow time of the bubbles, thereby improving the diffusion efficiency of the solution oxygen.

[0038] The inner and outer layers of the plurality of opposite rotating shafts 401 can be arranged in 2-8 groups according to the flow rate of the water body, and connected to the outer edge of the cover plate 14 at equal distances along the axis to ensure stability in the water body;

[0039] See also Figure 6-9The aeration control mechanism 5 also includes an aeration plate 501, and a support plate 502 is connected to the top of the aeration plate 501. A plurality of protective seats 503 are embedded on the top of the support plate 502 along the axis and at equal distances. A plurality of aeration nozzles 504 are arranged along the length direction of the protective seats 503, and the middle part of the outer peripheral side of the aeration nozzle 504 is slidably connected to the travel groove opened in the protective seat 503 through a hinged rod. A transmission rod 505 is slidably connected to the inner cavity of the protective seat 503. The cross-section of the transmission rod 505 is U-shaped. The bottom of the aeration nozzle 504 is rotatably connected between the two sides of the opening of the transmission rod 505 through a pin shaft, and the transmission rod 505 is away from the aeration nozzle. One end of the nozzle 504 is connected to a moving rod 506, and the moving rod 506 is slidably connected to one side of the protective seat 503, and one end of the moving rod 506 is connected to a triangular plate 508, and the triangular plate 508 extends to the outside of the protective seat 503, and the inner cavity of the aeration plate 501 is rotatably connected to a turntable 510, and the outer wall of the turntable 510 is equidistantly distributed along the axis. A plurality of protrusions 509 are arranged on the outer wall of the turntable 510 at equal distances, and the number of the protrusions 509 corresponds to the triangular plate 508, and the protrusions 509 are fitted with the inclined surfaces of the triangular plate 508 at the corresponding positions, so as to adjust the aeration angle by rotating the turntable 510 to push the triangular plate 508 and the aeration nozzle 504;

[0040] A spring 507 is sleeved on the outer wall of the moving rod 506, and both ends of the spring 507 are connected to the corresponding positions of the transmission rod 505 and the protective seat 503; the input end at the bottom of the turntable 510 is connected to the output end of the driving motor.

[0041] The bottom of the aeration nozzle 504 is connected to an aeration pipe 511, and the multiple aeration pipes 511 extend to the top through the aeration main pipe and are connected to the aeration pump 13 through the gas-liquid slip ring. The gas-liquid slip ring is connected to the bottom side of the cover plate 14, and the aeration pump 13 is connected to one side of the top of the cover plate 14;

[0042] In this embodiment, the turntable 510 is driven by the inner gear disc and the matching drive gear and drive motor, and the drive motor is a micro-control motor connected to an external fixed position such as the bottom side of the aeration plate 501 or the outside of the hard aeration tube 511 through a protective shell;

[0043] In another embodiment, the turntable 510 may be a rotating component with a clamp. After the clamp is tightened, the angle of the aeration nozzle 504 can be adjusted. After the angle is adjusted before launching, no real-time adjustment is performed to improve operational stability.

[0044] Specifically, when aeration is performed, in order to adapt to the flow rate and flow angle of the water body, the outer protrusion 509 can be rotated by rotating the turntable 510. The rotation of the protrusion 509 can squeeze the inclined surface of one side of the triangular plate 508. The movement of the triangular plate 508 drives the inner movable rod 506 to move. The movement of the movable rod 506 can drive the transmission rod 505 to push the hinged position on the bottom side of the aeration nozzle 504. At this time, the aeration nozzle 504 can be rotated through the middle hinged rod and sleeved to the aeration direction of the top, so that the airflow dispersion range during aeration can be controlled by multiple groups of aeration nozzles 504 arranged circumferentially, which is conducive to adapting to different water flow conditions and the tangent direction of the water flow after the device is installed, thereby improving the aeration treatment efficiency.

[0045] Moreover, the rotatable turntable 510 can adapt to the changes in the water flow to adjust the aeration angle, which is beneficial to improving the aeration treatment efficiency and the contact area with the water flow, improving the aeration efficiency, avoiding the need for a lateral flow velocity of the water body for vertical upward flow to increase the solution oxygen content of the surrounding water body, and improving the diffusion efficiency of dissolved oxygen during aeration.

[0046] Furthermore, to ensure the rotation angle of the aeration nozzle 504, the aeration nozzle 504 can move in the protective seat 503 to adapt to the arc rotation after the middle hinge rod is fully rotated in the stroke groove in the protective seat 503, thereby avoiding interference affecting the rotation stroke of the aeration nozzle 504;

[0047] The turbulence assembly 8 includes a plurality of turbulence discs 801. A sleeve is connected to the axis of the turbulence disc 801, and the sleeve is connected to the outside of the rotating shaft 401 at a corresponding position. The coaxial turbulence discs 801 are equidistant from each other, and the turbulence discs 801 are arranged at an inclined angle to the sleeve. The inclined angles of the turbulence discs 801 are different. A plurality of air holes 802 are formed through the top of the turbulence disc 801, and the plurality of air holes 802 have at least two different diameters.

[0048] See also Figure 3 The inclination angles of the multiple turbulence disks 801 can be set by rotating 15-25 degrees in sequence along the axis direction of the rotating shaft 401, so as to increase the turbulence energy of the aeration bubbles and the water flow through the turbulence disks 801 at different angles;

[0049] A plurality of guide plates 9 are arranged equidistantly along the axis of the outer wall of the inner treatment membrane 3. The cross-section of the guide plates (9) is wavy, and the guide plates 9 are located between the inner treatment membrane 3 and the outer filter membrane 2.

[0050] The top of the spoiler drum 7 is rotatably connected to the outer side of the screw seat 11 through a bearing, and the screw seat 11 is threadedly engaged with the reciprocating screw 6. The top of the reciprocating screw 6 is limited on the cover plate 14 through a bearing, and the top of the reciprocating screw 6 is transmission-connected to the drive motor 12, which is installed on the top of the cover plate 14.

[0051] Specifically: when the rotating shaft 401 rotates, the rotating shaft 401 can drive the external turbulence disk 801 to rotate. When the turbulence disk 801 rotates around the rotating shaft 401, it can tilt and disturb the water body. The inclined turbulence disk 801 can improve the full release of the aeration bubbles and guide the bubbles to generate turbulence, and the air holes 802 can disturb the bubbles when the aeration bubbles pass through, which is beneficial to improving the aeration contact effect. At the same time, when the output shaft of the driving motor 12 rotates, it can drive the reciprocating screw 6 to rotate. The rotation of the reciprocating screw 6 can drive the external screw seat 11 to move, and the screw seat 11 can move up and down through the reciprocating thread of the reciprocating screw 6. At this time, the screw seat 11 that moves up and down can drive the turbulence rotor 7 to move up and down. At this time, the reciprocating turbulence rotor 7 and the spiral blades 10 can drive the water in the water body to move in the axial space, and the force of the spiral blades 10 will drive the turbulence rotor 7 to rotate, which is beneficial to improve the full circulation and mixing of the water in the water body in the axial space, and further improve the aeration repair efficiency;

[0052] Furthermore, the drive motor 12 can also drive the reciprocating screw 6 to rotate through the gear set to reduce the rotational torque;

[0053] Wherein, corresponding hooks are provided on both sides of the top of the cover plate 14 for connecting to the outside of the water body through a traction rope;

[0054] Working principle: When in use, when the water flows or aeration generates flow, the turbine 1 can be forced to rotate and drive the inner gear ring 405 to rotate. The rotation of the gear ring 405 can drive the multiple driven gears 404 meshing on the inner side to rotate. The rotation of the driven gear 404 can drive the rotating shaft 401 located on the inner side to rotate. The rotation of the rotating shaft 401 can drive the outer turbulence component 8 to rotate and cut the inner aeration bubbles and drive the other side wheel body and the rotating shaft 401 located outside the outer filter membrane 2 to rotate through the top transmission belt 403. The rotation of the rotating shaft 401 can drive the external outer blades 402 to rotate, and the turbine 1 is driven by the water to flow by itself to achieve turbulent mixing between water bodies at different depths.

[0055] The rotation of the turntable 510 drives the outer protrusion 509 to rotate. The rotation of the protrusion 509 can squeeze the inclined surface of one side of the triangular plate 508. The movement of the triangular plate 508 drives the inner movable rod 506 to move. The movement of the movable rod 506 can drive the transmission rod 505 to push the hinged position on the bottom side of the aeration nozzle 504. At this time, the aeration nozzle 504 can be rotated by the middle hinge rod and sleeved on the aeration direction of the top. Through the multiple groups of aeration nozzles 504 arranged circumferentially, the airflow dispersion range during aeration can be controlled.

[0056] When the rotating shaft 401 rotates, the rotating shaft 401 can drive the external turbulence disk 801 to rotate. When the turbulence disk 801 rotates around the rotating shaft 401, it can tilt and disturb the water body. The inclined turbulence disk 801 can improve the full separation with the aeration bubbles and guide the bubbles to generate turbulence, and the air holes 802 can disturb the bubbles when the aeration bubbles pass through, which is beneficial to improving the aeration contact effect. At the same time, when the output shaft of the driving motor 12 rotates, it can drive the reciprocating screw 6 to rotate. The rotation of the reciprocating screw 6 can drive the external screw seat 11 to move, and the screw seat 11 can move up and down through the reciprocating thread of the reciprocating screw 6. At this time, the screw seat 11 that moves up and down can drive the turbulence rotor 7 to move up and down. At this time, the reciprocating turbulence rotor 7 and the spiral blades 10 can drive the water in the water body to move in the axial space. In addition, the force on the spiral blades 10 will drive the turbulence rotor 7 to rotate, which is beneficial to improve the full circulation and mixing of the water in the water body in the axial space, and further improve the aeration repair efficiency.
