Technical Field
[0001] This utility model belongs to the field of environmental protection and water treatment technology, specifically a high-efficiency air-water mixing river oxygenation device. Background Technology
[0002] River aeration devices are equipment that increase the dissolved oxygen content in water by increasing the surface area of contact between water and air. They are widely used in river management and aquatic ecological restoration. Existing aeration devices typically use methods such as mechanical stirring, bubble diffusion, or jet mixing to achieve air-water mixing and thus oxygenation.
[0003] Existing devices have certain limitations in practical applications, such as low air-water mixing efficiency, high energy consumption, and high maintenance costs, making it difficult to meet the demand for efficient and stable oxygenation in complex river environments. Furthermore, the aeration mechanisms of most devices are fixedly installed on a swing frame, resulting in poor adjustment flexibility and difficulty in adapting to river environments with different flow velocities and depths, thus limiting their applicability. Therefore, we propose a butt-welded adjustment device. Summary of the Invention

[0024] Example 1
[0025] refer to Figures 1 to 6 The device includes a support frame 1, a drive assembly 5, an adjustable aeration mechanism 8, and a guide assembly 15. The support frame 1 consists of a main beam 2, a secondary beam 3, and connecting parts. The main beam 2 is arranged parallel to both sides of the river channel, and the secondary beam 3 is vertically connected between the main beams 2 and fixed by the connecting parts, forming a stable rectangular frame structure. A sliding groove 4 is provided on the inner side of the main beam 2, with a T-shaped cross-section, to accommodate the sliding components of the adjustable aeration mechanism 8. A reinforcing rib is provided in the middle of the secondary beam 3 to enhance the overall rigidity of the support frame 1. The drive assembly 5 is located inside one end of the main beam 2 and includes a push rod motor 6, a push rod 7, and a control module 21. The push rod motor 6 is fixedly installed inside one end of the main beam 2. One end of the push rod 7 is fixedly connected to the push rod motor 6, and the other end is fixedly connected to the bottom of the sliding base 9. The control module 21 is fixedly installed on the inner wall of one end of the main beam 2 and is movably connected to the push rod motor 6 via a wire. The guide assembly 15 is fixedly installed on the inner side of the main beam 2, including a guide groove 16, a slider 17 and a limiting block 18. The guide groove 16 has a U-shaped cross section. The slider 17 is slidably installed in the guide groove 16, and its top is fixedly connected to the sliding base 9 of the adjustable aeration mechanism 8. The limiting block 18 is fixedly installed at both ends of the guide groove 16 to limit the movement range of the slider 17.
[0026] The adjustable aeration mechanism 8 is slidably mounted on the support frame 1 and includes a sliding base 9, an adjusting bracket 10, an aeration unit 11, and an adjusting mechanism 12. The sliding base 9 is slidably mounted in a groove 4 of the main beam 2, and its bottom is equipped with rollers. The rollers slide tightly against the groove 4, reducing friction and improving sliding stability. The adjusting bracket 10 is fixedly mounted on the top of the cylinder 13 and has multiple mounting holes inside for fixing the aeration unit 11. The aeration unit 11 is bolted to the mounting holes of the adjusting bracket 10 for injecting air into the water. The adjusting mechanism 12 includes a cylinder 13 and a solenoid valve 14. The cylinder body of the cylinder 13 is fixedly connected to the sliding base 9, and its output end is fixedly connected to the adjusting bracket 10 for adjusting the angle and height of the adjusting bracket 10.
[0027] The aeration unit 11 includes a shell, an air inlet pipe, a diffuser plate 19, and a conical diffuser tube 20. The shell is fixedly installed in the mounting hole of the adjusting bracket 10, and has an internal cavity for storing air. One end of the air inlet pipe is connected to an external air supply system, and the other end passes through the shell and communicates with the cavity, for supplying air into the shell. The diffuser plate 19 is fixedly installed at the bottom of the shell, and its surface has a plurality of micropores evenly distributed, with the diameter of the micropores ranging from 0.1 mm to 0.2 mm and the spacing between the micropores ranging from 0.1 mm to 0.2 mm, for dispersing air into fine bubbles. The conical diffuser tube 20 is fixedly installed below the diffuser plate 19, and its outlet is conical, with the diameter of the conical outlet gradually increasing from the inside to the outside, for increasing the diffusion range of the bubbles and improving the air-water contact area.
[0028] When using the device, the support frame 1 is first fixedly installed on both sides or the bottom of the river channel to ensure a firm connection between the main beam 2 and the secondary beam 3. The reinforcing ribs enhance the stability of the overall structure. After the push rod motor 6 of the drive assembly 5 is started, it pushes the sliding base 9 along the slide groove 4 of the main beam 2 through the push rod 7. The rollers at the bottom of the sliding base 9 are in close contact with the slide groove 4, reducing friction while ensuring smooth sliding.
[0029] The guide groove 16 of the guide assembly 15 is fixedly installed on the inner side of the main beam 2, and the slider 17 is slidably installed in the guide groove 16. The top of the slider 17 is fixedly connected to the sliding base 9, thereby guiding the movement trajectory of the sliding base 9. The limiting blocks 18 are fixedly installed at both ends of the guide groove 16 to limit the movement range of the slider 17 and prevent the sliding base 9 from disengaging from the guide groove 16. The design of the guide assembly 15 ensures the stability of the adjustable aeration mechanism 8 during movement and reduces the deviation caused by water flow impact.
[0030] The adjustable bracket 10 in the adjustable aeration mechanism 8 is fixedly connected to the top of the sliding base 9. The adjustable bracket 10 has multiple mounting holes for fixing the aeration units 11. The housing of each aeration unit 11 is fixedly installed in the mounting hole of the adjustable bracket 10. One end of the air inlet pipe is connected to an external air supply system, and the other end passes through the housing and communicates with the cavity. Air enters the cavity of the housing through the air inlet pipe. The diffuser plate 19 is fixedly installed at the bottom of the housing, and its surface has multiple micropores evenly distributed. These micropores disperse air into fine bubbles. The conical diffuser tube 20 is fixedly installed below the diffuser plate 19. Its conical outlet evenly sprays bubbles into the water. The conical outlet design increases the diffusion range of the bubbles and improves the air-water contact area.
[0031] The cylinder body of the regulating mechanism 12 is fixedly connected to the sliding base 9, and the output end is fixedly connected to the regulating bracket 10. The solenoid valve 14 controls the extension and retraction of the cylinder 13, thereby driving the regulating bracket 10 to adjust its height. The design of the regulating mechanism 12 enables flexible adjustment of the height of the aeration unit 11, which can adapt to river environments with different flow rates and depths.
[0032] According to actual needs, the push rod motor 6 drives the sliding base 9 to reciprocate along the slide groove 4 of the main beam 2 via the push rod 7 and the control module 21. The movement trajectory of the sliding base 9 is guided by the guide groove 16 and the slider 17 of the guide assembly 15, and the limiting block 18 restricts the movement range of the slider 17 to ensure that the sliding base 9 slides within a predetermined range. The multiple aeration units 11 in the adjustable aeration mechanism 8 are adjusted according to different requirements of water flow speed and depth by adjusting the aeration horizontal position and height through the adjusting mechanism 12 to achieve precise adjustment of the aeration unit 11. Air enters the shell cavity of the aeration unit 11 through the air inlet pipe, is dispersed into fine bubbles by the diffuser plate 19, and then diffuses into the water through the conical diffuser pipe 20. The conical outlet design increases the diffusion range of the bubbles, improves the air-water contact area, and allows the air and water to fully contact each other, thereby improving the air-water mixing efficiency.
[0033] The above embodiments describe in detail the specific structure and operating principle of the high-efficiency air-water mixing river aeration device, demonstrating the connection, position, and cooperation relationships between the various components. Through the stable bearing of the support frame 1, the power transmission of the drive component 5, the flexible adjustment of the adjustable aeration mechanism 8, and the precise guidance of the guide component 15, the device achieves high-efficiency aeration function in different river environments.
[0034] To enable those skilled in the art to fully understand and implement this utility model, the specific implementation principle of this utility model is further supplemented below with a specific application scenario.
[0035] Example 2
[0036] First, the support frame 1 is fixedly installed on the banks of the river on both sides. The main beam 2 is set parallel to both sides of the river, and the secondary beam 3 is vertically connected between the main beam 2 and fixed with connectors to form a rectangular frame structure. The addition of reinforcing ribs enhances the rigidity of the overall structure, ensuring the stability of the device under the impact of water flow. Subsequently, the external air supply system is connected to the shell of the aeration unit 11 through the air inlet pipe, and air is delivered to the internal cavity of the shell for storage. The diffuser plate 19 is fixed to the bottom of the shell, and its surface has uniformly distributed micropores that disperse the air into fine bubbles with a diameter of 0.5 mm to 1 mm. The spacing between the micropores is controlled within the range of 2 mm to 3 mm to ensure the uniformity and stability of the bubbles. The conical diffuser pipe 20 is fixed below the diffuser plate 19, and its conical outlet design allows the bubbles to gradually diffuse during the spraying process, increasing the contact area between the bubbles and the water.
[0037] After the drive assembly 5 is started, the push rod motor 6 drives the push rod 7 to push the sliding base 9 along the slide groove 4 of the main beam 2 to move its position. The control module 21 ensures that the push rod 7 can perform reciprocating motion correctly. The rollers at the bottom of the sliding base 9 are in close contact with the slide groove 4, reducing friction and improving the smoothness of sliding. The guide groove 16 in the guide assembly 15 is fixedly opened inside the main beam 2, and the slider 17 is slidably installed in the guide groove 16, with its top fixedly connected to the sliding base 9, thereby accurately guiding the movement trajectory of the sliding base 9. The limit blocks 18 are installed at both ends of the guide groove 16, limiting the movement range of the slider 17 and preventing the sliding base 9 from disengaging from the guide groove 16.
[0038] In actual operation, the adjustable aeration mechanism 8 is dynamically adjusted according to the needs of the river environment. The solenoid valve 14 in the adjustment mechanism 12 controls the extension and retraction of the cylinder 13 to drive the adjustment bracket 10 to change its height. This design allows multiple aeration units 11 to adjust their respective aeration heights according to different requirements of water flow velocity and depth, ensuring full contact between air and water.
[0039] Air enters the shell cavity of the aeration unit 11 through the air inlet pipe, is dispersed into fine bubbles by the diffuser plate 19, and then sprayed into the water through the conical diffuser tube 20. The conical outlet design of the conical diffuser tube 20 allows the bubbles to gradually diffuse during the spraying process, increasing the coverage area of the bubbles and further improving the air-water contact area. The microporous design of the diffuser plate 19 ensures the uniformity and stability of the bubbles, while the conical outlet of the conical diffuser tube 20 enables the directional diffusion of the bubbles, thereby significantly improving the air-water mixing efficiency.
