Description

Technical Field

[0001] This utility model belongs to the field of water environment management technology, specifically, it relates to a wind-water complementary driven self-oxygenation ecological purification device for river network water bodies. Background Technology

[0002] The fundamental challenge to water purification in plain river network areas stems from the "stillness" and "weakness" caused by their "flat" terrain. Slow or even stagnant water flow almost completely eliminates their physical self-purification capabilities (such as flushing and diluting pollutants) and chemical self-purification capabilities (such as atmospheric reoxygenation), which is the core of all the problems. Against this backdrop, three major challenges intertwine, forming a vicious cycle: First, persistent physical turbidity occurs because fine sediments lack the necessary settling force, and any slight disturbance leads to resuspension of bottom sediment, resulting in extremely low water transparency. This not only affects the landscape but, more importantly, inhibits the recovery of the underwater ecosystem. Second, rampant biological pollution occurs because stagnant water combined with high concentrations of nitrogen and phosphorus nutrients from agriculture and daily life provides a perfect breeding ground for algal blooms, which further exacerbate hypoxia and turbidity. Third, and most intractable, is "endogenous pollution." The bottom sediment formed by the settling of large amounts of pollutants continuously releases nutrients in an anaerobic environment, acting like an underwater "pollution bomb." Even if external pollution discharge is cut off, the water body will remain eutrophic for a long time. This situation, characterized by poor hydraulic conditions, complex pollution sources, and deteriorating internal circulation, renders any single treatment technology ineffective, necessitating a comprehensive approach. The challenges are far greater than managing a single flowing river. Common treatment methods include: Aeration: using aerators, flow promoters, etc., which is energy-intensive, has high operation and maintenance costs, and impacts the river landscape. Chemical dosing: such as flocculants, while rapidly settling suspended solids, may disrupt the aquatic ecological balance and has short-lived effects. Floating bed method: occupying river surface area, potentially affecting navigation and flood control, and offering limited suppression of disturbances in the middle and bottom layers of the water.

[0003] Patent document CN206278981U discloses a floating island-type water purification device for river management. It includes a support frame and a circular planting trough mounted on the support frame. An aerator is installed at the center of the planting trough, and the aerator is connected to the support frame via a traction rope. This utility model provides a floating island-type water purification device for river management that improves dissolved oxygen and water quality by incorporating an aerator, while also being environmentally friendly and aesthetically pleasing.

[0004] For example, patent document CN206278981U uses aeration and oxygenation combined with an ecological floating bed, which not only occupies a large area, but also causes significant disturbance to its operation by the water body, and the aeration and oxygenation device used has high operating and maintenance costs.

[0005] To improve dissolved oxygen and water clarity per unit area while reducing reliance on external energy sources, this invention presents a wind-water hybrid-driven self-oxygenating ecological purification device for river networks, thus solving the aforementioned problems. Utility Model Content

[0006] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a wind-water complementary driven self-oxygenation ecological purification device for river network water bodies.

[0007] According to the present invention, a wind-water complementary driven self-oxygenating ecological purification device for river network water bodies includes: a wind-powered water lifting unit, a hydraulic drive structure, and an ecological purification unit. The wind-powered water lifting unit includes a hemispherical wind cup, a water lifting cylinder, and a rotating shaft. The hemispherical wind cup is circumferentially fixed to the rotating shaft. The water lifting cylinder is set above the riverbed and extends vertically. Both ends of the water lifting cylinder are open, and a spiral blade is rotatably connected between the two ends. The rotating shaft is coaxially and vertically connected to the top of the spiral blade axis, and the spiral blade axis limits the rotation shaft circumferentially. The rotating shaft is located below the hemispherical wind cup and is fitted with and rotatably connected to a buoyancy disk. The rotating shaft limits the buoyancy disk vertically.

[0009] Preferably, the base is filled with counterweights.

Detailed Implementation

[0026] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0027] like Figures 1-3 As shown, a wind-water complementary driven river network water self-oxygenation ecological purification device includes: a wind-powered water lifting unit 1, a hydraulic drive structure 2, and an ecological purification unit 3.

[0028] The wind-powered water lifting unit 1 includes a hemispherical wind cup 11, a water lifting cylinder 12, and a rotating shaft 13. The hemispherical wind cup 11 is circumferentially fixed to the rotating shaft 13. The water lifting cylinder 12 is positioned above the riverbed and extends vertically. Both ends of the water lifting cylinder 12 are open, and a spiral blade 5 is rotatably connected between the two ends. The rotating shaft 13 is coaxially and vertically connected to the top of the axis of the spiral blade 5, and the axis of the spiral blade 5 limits the circumferential movement of the rotating shaft 13. The rotating shaft 13 is located below the hemispherical wind cup 11, and a buoyancy disk 6 is fitted and rotatably connected to it. The rotating shaft 13 vertically limits the buoyancy disk 6.

[0029] The hydraulic drive structure 2 includes a turbine blade assembly 21, the turbine blade assembly 21 is horizontally arranged along the river channel, and the turbine blade assembly 21 is driven to the lower end of the helical blade 5 shaft.

[0030] The ecological purification unit 3 includes a biological packing frame 31, which is fixed to the upper and lower ends of the outer wall of the water lifting cylinder 12, and the biological packing 4 is fixed between the biological packing frames 31.

[0031] The working principle of this application is as follows: the rotation of the water lifting cylinder 12 drives the bottom water flow upward, making it easier for organic matter at the bottom to decompose. At the same time, the water flow rich in organic matter can achieve higher decomposition efficiency as it passes through the biological filler 4. The water lifting cylinder 12 is equipped with a driving structure at both the top and bottom. It is driven by wind power when there is wind and by water flow when there is no wind, ensuring that the biological filler 4 is in constant contact with the flowing water, thereby improving the purification effect and achieving all-weather river purification by relying on natural energy.

[0032] Specifically, the hydraulic drive structure 2 also includes a base 22 and a drive shaft 23. The base 22 is placed at the bottom of the riverbed and can be filled with counterweights. The drive shaft 23 is coaxially connected to the turbine blade assembly 21 and is axially and horizontally rotatably connected to the base 22. The drive shaft 23 and the helical blade 5 are respectively provided with bevel gears, and the two bevel gears mesh with each other.

[0033] The water lifting cylinder 12 is fixedly connected to the base 22. The spiral blade 5 is rotatably connected to the base 22. The spiral blade 5 includes a vertical shaft and blades that spiral around the vertical shaft and rise. The edge of the blades is close to the inner wall of the water lifting cylinder 12. The rotation of the spiral blade 5 drives water to flow from bottom to top along the water lifting cylinder 12.

[0034] The bottom end of the rotating shaft 13 is provided with a cross spline, which is connected to the top of the axis of the helical blade 5. The axis of the helical blade 5 is circumferentially limited by the cross spline. A retaining ring is fitted on each of the upper and lower sides of the rotating shaft 13 and the buoyancy disk 6. The two retaining rings vertically limit the buoyancy disk 6. The buoyancy disk 6 drives the hemispherical wind cup 11 to float on the water surface. The cross spline allows the rotating shaft 13 to maintain the driving force on the helical blade 5 while adapting to the rise and fall of the buoyancy disk 6.

[0035] The biological packing frame 31 is arranged in a ring, and there is a gap between the biological packing frame 31 and the water lifting cylinder 12. The elastic biological packing 4 is stably fixed by the biological packing frame 31.

[0036] In one embodiment, three hemispherical wind cups 11 are evenly spaced around the circumference of the axis of rotation 13.

[0037] The working process of this application is driven by a "feng shui complementarity and top-down coordination" mechanism: Wind-driven mode (dominant): When wind blows, it drives the hemispherical wind cup 11 to rotate. The hemispherical wind cup 11 drives the rotating shaft 13, which in turn drives the spiral blades 5 to rotate inside the water-lifting cylinder 12. The spiral blades 5 agitate the river water at the bottom of the channel to the surface, promoting water exchange between the upper and lower layers. This brings nutrients from the bottom layer to the sunlit surface, promoting phytoplankton growth, preventing the outbreak of "endogenous pollution," and enhancing the water body's self-purification capacity. At the same time, the water lifting process transports dissolved oxygen from the surface water to the oxygen-deficient bottom layer, improving the living environment of aquatic organisms and inhibiting the production of harmful substances, thereby comprehensively enhancing the water body's self-purification capacity and ecosystem vitality.

[0038] Hydraulic drive mode (auxiliary): When there is a weak water flow in the river, the water flow drives the turbine blade assembly 21 to rotate, which in turn assists the rotation of the spiral blade 5 via the drive shaft 23 to perform the water lifting operation. Even in windless weather, as long as the water is flowing, the device can continue to operate.

[0039] Ecological purification process: As the lifted and agitated river water flows through the annular biological packing frame 31, it comes into full contact with the high-density biofilm attached to the elastic biological packing 4. After receiving sufficient oxygen and nutrients, the aerobic microorganisms in the biofilm efficiently degrade pollutants such as organic matter and ammonia nitrogen in the water, thereby inhibiting algae growth, promoting the flocculation and sedimentation of suspended solids, and fundamentally improving the clarity of the water.
