Description

Technical Field

[0001] This utility model belongs to the field of river management technology, specifically relating to an aeration device for river management. Background Technology

[0002] In the process of river management, submersible aerators are needed to purify water. Submersible aerators inject "microbubbles" directly into untreated sewage through a diffuser impeller. Under the combined action of coagulants and flocculants, suspended solids undergo physical and chemical flocculation, forming large suspended flocs. Under the buoyancy of the bubble clusters, the "flocs" float to the surface of the liquid to form scum, which is then separated from the water by a scum scraper, thus achieving the treatment and cleaning of river water.

[0003] Existing aeration devices cannot be moved to a specified depth for aeration, and it is inconvenient to adjust the aeration depth in the water.

[0004] The patent with publication number CN218810900U discloses an integrated mixing and aeration machine for river management, including a submersible aerator, a spring-shaped hose, a connecting shell, a drive motor, and a connecting cylinder. The top center of the submersible aerator is fixedly connected to an air supply pipe, and the top end of the air supply pipe is fixedly connected to a spring-shaped hose. Connecting shells are fixed on both sides of the submersible aerator. A drive motor is fixed at the bottom of the connecting shell. A rotating shaft is fixed at the output end of the drive motor. A connecting cylinder is movably connected to the lower part of the rotating shaft. Connecting rods are fixed in a ring array on the bottom surface of the connecting cylinder.

[0005] The aeration unit disclosed in the aforementioned patent can only perform aeration at a certain water level because it does not have a structure for raising and lowering in the water. It cannot adjust the aeration depth. Therefore, how to provide an aeration device for river management that can adjust the aeration depth in river water is a problem that urgently needs to be solved by those skilled in the art.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-3 As shown, this utility model provides an aeration device for river management, including a floating platform 1. A winding mechanism 3 is fixedly connected to the bottom end of the floating platform 1. A telescopic mechanism 4 is fixedly connected to the bottom end of the winding mechanism 3. The bottom end of the telescopic mechanism 4 is connected to a lifting platform 5. A perforated cylindrical base 6 is fixedly connected to the bottom end of the lifting platform 5. An aeration component is provided inside the lifting platform 5. A ventilation duct 2 is connected to the aeration component. The end of the ventilation duct 2 away from the aeration component extends to the outside through the lifting platform 5, the telescopic mechanism 4, the winding mechanism 3, and the floating platform 1 in sequence. In addition, a through hole is provided on the floating platform 1 to allow the first airbag 1.1 inside the floating platform 1 to directly contact the water.

[0024] In this embodiment, the winding mechanism 3 includes a winding box 3.1. A connecting shaft is fixedly connected inside the winding box 3.1. The connecting shaft is fixedly connected to the center of a spiral spring 3.4. The outer circumferential side of the spiral spring 3.4 is fixedly connected to the inner wall of the annular winding drum 3.3. Three first annular partitions are fixedly connected to the outer wall of the annular winding drum 3.3, dividing the outer wall of the annular winding drum 3.3 into two winding slots. A fixing member 3.5 is also fixedly connected to the middle first annular partition of the annular winding drum 3.3. The middle position of the ventilation duct 2 is fixed to the annular winding drum 3.3 by the fixing member 3.5. The two ends of the ventilation duct 2 are respectively wound around the middle first ring. Within the winding slots on both sides of the partition plate, one end of the ventilation duct 2 passes through the top of the winding box 3.1 and connects to the floating platform 1, while the other end passes through the bottom of the winding box 3.1 and connects to the telescopic mechanism 4. An annular baffle 3.2 is also fixedly connected to the inner wall of the winding box 3.1. When the ventilation duct 2 is stretched, it drives the annular winding drum 3.3 and the spiral spring 3.4 to rotate. When the lifting platform 5 rises, the spiral spring 3.4 can drive the annular winding drum 3.3 to rewind, thereby ensuring the recovery of the ventilation duct 2. In addition, the end of the ventilation duct 2 away from the underwater fan extends to a position a certain distance above the floating platform 1 to prevent the top of the ventilation duct 2 from descending and contracting when the annular winding drum 3.3 drives the ventilation duct 2 to rewind.

[0025] In this embodiment, the telescopic mechanism 4 includes an outer telescopic cylinder and an inner telescopic cylinder. The outer telescopic cylinder is sleeved on the inner telescopic cylinder. The bottom end of the outer telescopic cylinder is fixedly connected to the lifting platform 5, and the top end of the inner telescopic cylinder is fixedly connected to the winding mechanism 3. An outer wall protrusion is provided at the bottom end of the outer wall of the inner telescopic cylinder, and an inner wall protrusion is provided at the top end of the inner wall of the outer telescopic cylinder. A ventilation duct 2 is provided inside the inner telescopic cylinder. The outer telescopic cylinder and the inner telescopic cylinder can slide relative to each other to realize the telescopic mechanism 4. In addition, multiple telescopic cylinders can be added, or the length of the outer telescopic cylinder and the inner telescopic cylinder can be increased to increase the overall length of the telescopic mechanism.

[0026] In this embodiment, a second annular partition is provided inside the lifting platform 5, dividing the interior of the lifting platform 5 into a driving chamber and a floating chamber. An aeration assembly and an underwater stirring assembly are provided in the driving chamber. The aeration assembly includes an underwater fan 7 and a water pump 10. A second airbag 9 is provided in the floating chamber. The underwater fan 7 is connected to a ventilation duct 2. A first ventilation branch pipe 7.1 and a second ventilation branch pipe 7.2 are also connected to the underwater fan 7. The end of the first ventilation branch pipe 7.1 away from the underwater fan 7 passes through the second annular partition and connects to the second airbag 9. The second ventilation branch pipe 7.2 passes through the bottom of the inner wall of the lifting platform 5 and communicates with the porous cylindrical base 6. Valves are provided on both the first ventilation branch pipe 7.1 and the second ventilation branch pipe 7.2. An exhaust port 9.1 is provided on the second airbag 9, and an exhaust valve is connected to the exhaust port 9.1. The system includes a vent pipe that penetrates the inner wall of the floating chamber and extends to the outside. A valve is installed on the vent pipe. Two suction pipes 10.1 are connected to the water pump 10. These two suction pipes 10.1 penetrate the second annular partition and the top of the inner wall of the drive chamber, respectively. The end of the suction pipe 10.1 penetrating the second annular partition, away from the water pump 10, is connected to the floating chamber. The end of the suction pipe 10.1 penetrating the top of the inner wall of the drive chamber, away from the water pump 10, is connected to the outside. The valve can be an electric valve. The water pump 10 and the suction pipes 10.1 can replenish water to the floating chamber, increasing the weight of the lifting platform 5 and causing it to descend. They can also drain water from the floating chamber, reducing the weight of the lifting platform 5 and causing it to rise. The second airbag 9 can be inflated and deflated via the underwater fan 7, the exhaust port 9.1, and the first ventilation branch pipe 7.1.

[0027] In this embodiment, the underwater stirring assembly includes an underwater drive motor 8 and an inverted umbrella impeller 8.1. The inverted umbrella impeller 8.1 is disposed at the top of the inner wall of the porous cylindrical base 6. The underwater drive motor 8 is fixed at the bottom of the inner wall of the drive cavity. The output end of the underwater drive motor 8 passes through the bottom of the inner wall of the drive cavity and is connected to the inverted umbrella impeller 8.1. The inverted umbrella impeller 8.1 rotates under the drive of the underwater drive motor 8, thereby achieving uniform mixing of gas and liquid.

[0028] In this embodiment, the porous cylindrical base 6 is provided with multiple ventilation holes. The ventilation holes of the porous cylindrical base 6 allow water to enter the porous cylindrical base 6, which facilitates gas-liquid mixing during aeration and improves the aeration effect.

[0029] In this embodiment, the floating platform 1 is provided with a plurality of first airbags 1.1, and the outer wall of the floating platform 1 is provided with a plurality of through holes that can communicate with the outside world to realize the lifting and lowering control of the floating platform using the first airbags 1.1. A connecting air port can be provided on the floating platform 1, and a connecting pipe is added to the first airbag 1.1 and connected to the outside world through the connecting air port to facilitate the inflation and deflation of the first airbag.

[0030] Working principle: The first airbag 1.1 inside the floating platform 1 is inflated to ensure the platform remains afloat. The underwater fan 7, water pump 10, and valves on the first ventilation branch pipe 7.1 are activated to control the water content in the floating chamber and the gas content in the second airbag 9. When the gas content in the second airbag 9 is excessive, the excess gas is discharged through the exhaust port 9.1, allowing the entire lifting platform 5 to rise and fall in the water, thus controlling the aeration depth. Simultaneously, when the lifting platform 5 rises and falls, the telescopic mechanism 4 ensures overall expansion and contraction. The ventilation duct 2 expands and contracts due to the expansion and contraction of the lifting platform. When the tube extends or shortens, it drives the annular winding drum 3.3 to rotate. The rotation of the annular winding drum 3.3 drives the spiral spring 3.4 to rotate and store energy, which facilitates the automatic retraction and shortening of the ventilation duct 2. The valve on the first ventilation branch pipe 7.1 is closed and the valve on the second ventilation branch pipe 7.2 is opened. The underwater drive motor 8 is started. The underwater drive motor 8 drives the inverted umbrella impeller 8.1 to rotate. At the same time, the underwater fan 7 aerates the water through the second ventilation branch pipe 7.2 at the porous cylindrical base 6. The inverted umbrella impeller 8.1 can ensure sufficient contact and mixing of river water and air, and improve the aeration effect.
