Description

Technical Field

[0001] This invention relates to the field of wetland sediment treatment equipment technology, specifically, to a wetland sediment ecological restoration and oxygenation purification device. Background Technology

[0002] Wetland sediment is a crucial component of wetland ecosystems. Under the continuous impact of urbanization and agricultural non-point source pollution, large amounts of pollutants accumulate in wetland sediment. When the pollutant load in the sediment exceeds its self-purification capacity, it not only pollutes the wetland water but also damages the structure and function of the entire wetland ecosystem. Therefore, remediation of polluted wetland sediment is necessary. Among existing wetland sediment remediation technologies, in-situ remediation, compared to ex-situ dredging, does not require large-scale excavation and relocation of sediment, resulting in lower engineering workload and less disturbance to the original wetland ecology. It is a more valuable remediation method for widespread application. In-situ aerobic remediation technology replenishes oxygen to the sediment, promoting the decomposition of pollutants by aerobic microorganisms, thereby achieving sediment remediation. Therefore, it requires supporting aeration equipment. However, most existing in-situ oxygenation and remediation equipment only oxygenates the surface layer of the water, making it difficult for oxygen to penetrate into the sediment. At the same time, due to the density of the sediment, the oxygen penetration range is very limited, resulting in poor remediation effect. Some remediation equipment is only equipped with simple aeration and stirring devices, which have uneven stirring range and make it difficult to fully stir the sediment. Pollutants in the sediment cannot be effectively released, and oxygen cannot be fully introduced into the sediment. The overall remediation efficiency is low and it is difficult to meet the needs of in-situ sediment ecological restoration of large areas of wetlands. Summary of the Invention

[0003] The technical problem to be solved by this invention is to provide a wetland sediment ecological restoration and oxygenation purification device. By using a sediment stirring component in conjunction with an oxygenation structure, oxygen can be directly supplied to the sediment area while stirring the sediment to promote the release of pollutants. This enhances the degradation effect of aerobic microorganisms on pollutants in the sediment. Compared with traditional restoration devices that only oxygenate the surface of the water body, this device is more targeted and effective in oxygenation and restoration.

[0004] A wetland sediment ecological restoration and oxygenation purification device includes a hull, with a cover fixedly connected to both ends of the hull via connecting rods. A pipeline is fixedly installed on the upper side of the cover, and an oxygenation pipe is installed inside the pipeline. The oxygenation pipe can be raised and lowered within the pipeline via a lifting component. An exhaust head is fixedly connected to the lower end of the oxygenation pipe. The exhaust head is fixedly installed on a mounting plate, and a sediment stirring component is installed on the mounting plate. The bottom sediment stirring component has symmetrical actuating claw one and symmetrical actuating claw two, which can be driven by a driving component to swing actuating claw one and actuating claw two to stir the bottom sediment. The upper end of the oxygenation pipe is fixedly connected to an air pump via a flexible hose, and the air pump is fixed to the hull.

[0005] Furthermore, the driving component includes a drive motor, which is fixedly mounted on the mounting plate. The output shaft of the drive motor is fixedly connected to a drive gear. First gears are respectively provided on both sides of the drive gear, and the first gears mesh with the drive gear. Each first gear meshes with a second gear. The central shafts of each second gear and the first gear are rotatably connected to a fixed rod. The fixed rod is fixedly connected to the mounting plate via a fixed block, which is L-shaped. The central shaft of the second gear is fixedly connected to one end of a first connecting rod, which is H-shaped. The middle shaft of the first connecting rod is rotatably connected to a second actuating pawl. The end of the second actuating pawl near the second gear is rotatably connected to one end of a long rod. The other end of the long rod is rotatably connected to the fixed block. The other end of the first connecting rod is fixedly connected to one end of a second connecting rod. The other end of the second connecting rod is rotatably connected to the first actuating pawl. The end of the first actuating pawl near the second gear is rotatably connected to one end of the long rod. The other end of the long rod is rotatably connected to the fixed block.

[0006] Furthermore, the bottom mud stirring components are respectively provided on both sides of the mounting plate, and each bottom mud stirring component has a symmetrical actuating claw one and a symmetrical actuating claw two.

[0007] Furthermore, both the first and second actuating claws are airfoil-shaped.

[0008] Furthermore, a housing is fixedly provided on one side of the fixing rod, and the driving gear, the first gear and the second gear are all disposed inside the housing, with the central shafts of the driving gear, the first gear and the second gear passing through the housing.

[0009] Furthermore, the lifting assembly includes a motor cavity, which is fixed to the cover. The output shaft of the motor fixed inside the motor cavity is fixedly connected to a take-up shaft. The take-up shaft is fixedly connected to one end of a pull chain, and the other end of the pull chain is fixed to a connecting block. The connecting block is fixedly connected to the cover.

[0010] Furthermore, the connecting blocks are symmetrically arranged on the cover, and the pull chain is located in the middle of the area between the symmetrical connecting blocks.

[0011] Furthermore, both the first and second actuating claws are provided with several round holes.

[0012] Compared with the prior art, the advantages and positive effects of the present invention are: By using a symmetrically arranged set of multiple actuating claws in conjunction with a linkage gear transmission mechanism, synchronous reciprocating agitation of multiple claws can be achieved. When two actuating claws move inward, two actuating claws move outward, and when two actuating claws move outward, two actuating claws move inward. This ensures that actuating claws one and two are subjected to symmetrical forces during operation, with opposite directions of movement on both sides. The forces cancel each other out, preventing deviation during force application, protecting actuating claws one and two, and extending their service life. By combining bottom sediment agitation components with an oxygenation structure, oxygen can be directly supplied to the bottom sediment area while agitating the sediment to promote the release of pollutants. This enhances the degradation effect of aerobic microorganisms on pollutants in the sediment. Compared with traditional remediation equipment that only oxygenates the surface of the water, the oxygenation and remediation are more targeted and have better results. The lowering depth of the cover can be quickly adjusted using the lifting assembly to adapt to the restoration needs of wetlands at different depths, and also facilitates equipment transfer and maintenance.

[0015] The following detailed description of a specific embodiment of the present invention is provided in conjunction with the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0016] In the description of this invention, it should be understood that the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0017] Movable and rotating connections include hinge connections, bearing connections, pin connections, etc. The terms mentioned above all refer to two components that cannot move relative to each other at the connection point, but can rotate relative to each other. The above explanation, combined with the accompanying drawings, can unambiguously identify the structure. The above explanation is from mechanical design manuals and Baidu Encyclopedia, and is common knowledge familiar to those skilled in the art.

[0018] A wetland sediment ecological restoration and oxygenation purification device includes a hull 1. The two ends of the hull 1 are respectively fixedly connected to a cover 4 by connecting rods 2. A pipe 3 is fixedly installed on the upper side of the cover 4. An oxygenation pipe 6 is installed in the pipe 3. The oxygenation pipe 6 can be raised and lowered in the pipe 3 by a lifting component. The lower end of the oxygenation pipe 6 is fixedly connected to an exhaust head 7. The exhaust head 7 is fixedly installed on a mounting plate 21. A sediment stirring component is installed on the mounting plate 21. like Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, when the two actuating claws 14 move inward, the two actuating claws 16 move outward; when the two actuating claws 14 move outward, the two actuating claws 16 move inward, thus achieving symmetrical force distribution on the actuating claws 14 and 16 during operation. Figure 4 and Figure 6The movement shown is in opposite directions on both sides, and the forces they are subjected to cancel each other out, preventing deviation when subjected to force, protecting the first toggle 14 and the second toggle 16, and extending their service life.

[0019] The sediment agitator has symmetrical agitator claws 14 and symmetrical agitator claws 16. The sediment agitator is positioned on both sides of the mounting plate 21. Each sediment agitator has symmetrical agitator claws 14 and 16, which can be driven by a drive component to swing, thus agitating the sediment. The drive component includes a drive motor 10, which is fixedly mounted on the mounting plate 21. The output shaft of the drive motor 10 is fixedly connected to a drive gear 11. First gears 12 are positioned on both sides of the drive gear 11, meshing with each other. Each first gear 12 meshes with a second gear 13, and the central axes of each second gear 13 and the first gear 12 are rotatably connected. A fixing rod 18 is connected to the mounting plate 21 via a fixing block 17, which is L-shaped. The central shaft of the second gear 13 is fixedly connected to one end of the first connecting rod 15, which is H-shaped. The middle shaft of the first connecting rod 15 is rotatably connected to a second actuating pawl 16. The end of the second actuating pawl 16 near the second gear 13 is rotatably connected to one end of a long rod 19. The other end of the long rod 19 is rotatably connected to the fixing block 17. One end of the other side of the first connecting rod 15 is fixedly connected to one end of the second connecting rod 20. The other end of the second connecting rod 20 is rotatably connected to a first actuating pawl 14. The end of the first actuating pawl 14 near the second gear 13 is rotatably connected to one end of a second long rod 22. The other end of the second long rod 22 is rotatably connected to the fixing block 17. The upper end of the oxygenation pipe 6 is fixedly connected to an air pump via a flexible hose, and the air pump is fixed to the hull 1.

[0020] In this embodiment, the lifting assembly can lower the oxygenation pipe 6, allowing the exhaust head 7 to reach the upper side of the bottom sediment area. At this time, the first actuating claw 14 and the second actuating claw 16 extend into the bottom sediment. The air pump delivers air to the exhaust head 7 through the oxygenation pipe 6. After the air is discharged from the exhaust head 7, it can replenish dissolved oxygen to the bottom sediment and water, enhance the degradation of pollutants by aerobic microorganisms, and also drive water flow by causing the air bubbles to rise. The drive motor 10 drives the drive gear 11 to rotate, and the drive gear 11 synchronously meshes with the first gear 12 on both sides. The first gear 12 then drives the meshing first gear 12 to rotate. When the second gear 13 rotates, it drives the first connecting rod 15 to make a circular motion. The middle part of the first connecting rod 15 drives the second actuating claw 16, and the other end drives the first actuating claw 14 through the second connecting rod 20. In conjunction with the long rod 19 and the long rod 22 respectively hinged to the fixed block 17, the first actuating claw 14 and the second actuating claw 16 can be driven to swing back and forth, thereby fully agitating the wetland bottom sediment and mixing the bottom sediment with the water. The cover 4 set on both sides of the hull 1 can limit the agitation and oxygenation range to inside the cover 4, improving the targeting and effect of bottom sediment remediation.

[0021] Both the first actuating claw 14 and the second actuating claw 16 are wing-shaped, and both the first actuating claw 14 and the second actuating claw 16 have several round holes.

[0022] The lightweight design with a circular hole not only reduces the overall weight of the agitator claw, decreasing the load on the mechanical structure during rotation and reducing power loss of the drive motor 10, but also allows some water to pass through the hole during the reciprocating agitation of the bottom sediment. This reduces water resistance during agitation, making the oscillating agitation process smoother, reducing wear and tear on the equipment, and extending its service life. Simultaneously, the airfoil-shaped structural design increases the force-bearing area during agitation, enhancing the agitation effect on the bottom sediment.

[0023] A housing 9 is fixedly mounted on one side of the fixing rod 18. The driving gear 11, the first gear 12, and the second gear 13 are all disposed inside the housing 9, and the central shafts of the driving gear 11, the first gear 12, and the second gear 13 all pass through the housing 9. The housing 9 serves to protect the gears and other internal components, and a sealing ring is used to seal the space between the gears and the housing 9.

[0024] In this invention, water-resistant silicone sealant is applied to each assembly surface to fill the micro-gaps in the machining process; all screws are made of 316L / titanium alloy to prevent corrosion, rust penetration, and water seepage; the cover is made of titanium alloy and duplex stainless steel; the housing is thickened to resist pressure and deformation and prevent cracking; the input / output rotating shaft is waterproofed by a floating oil seal; heavy-duty low-speed joint gears are used; and a metal floating ring is used in conjunction with an O-ring to adapt to shaft eccentric deformation and resist deep water alternating water pressure.

[0025] Example 2: The lifting assembly includes a motor cavity 5, which is fixed on the cover 4. The output shaft of the motor fixed inside the motor cavity 5 is fixedly connected to a take-up shaft 501. The take-up shaft 501 is fixedly connected to one end of a pull chain, and the other end of the pull chain is fixed to a connecting block 8. The connecting block 8 is fixedly connected to the cover 4.

[0026] The connecting blocks 8 are symmetrically arranged on the cover 4, and the pull chain is located in the middle of the area between the symmetrical connecting blocks 8.

[0027] In this embodiment, the rewind shaft 501 can be rotated by the forward and reverse rotation of the motor, which in turn rewinds or releases the traction chain, thereby causing the connecting block 8 and the entire cover 4 to rise and fall vertically. This adjusts the height of the cover 4 in the water to adapt to different depth treatment needs and allows for quick lifting of the entire structure out of the water during equipment maintenance and relocation, making operation very convenient. Placing the traction chain in the middle of the symmetrical connecting blocks 8 ensures even force distribution on the traction chain, keeping the cover 4 stable during lifting and falling, avoiding tilting and jamming, and ensuring stable structural operation. This method is waterproof, simple, and low-cost. However, its disadvantage is that it cannot precisely control the posture and requires a counterweight to maintain the center of gravity. Therefore, a heavy metal material is used as a counterweight element at the position where the oxygenation pipe 7 is fixedly connected to the upper side of the mounting plate 21 to maintain the center of gravity.

[0028] Example 3: The lifting assembly is a telescopic, segmented electric telescopic arm structure that can precisely control the height and position of the cover 4 and the first and second actuating claws 14 and 16. However, its disadvantages are high cost, difficulty in waterproofing, and easy damage when probing the bottom.

[0029] The equipment is navigated to the wetland area to be restored. Based on the water depth of the area, the lowering depth of the cover 4 is adjusted using the lifting assembly, allowing the sediment agitator on the mounting plate 21 to extend into the wetland sediment, and the exhaust head 7 to reach the area above the sediment. The air pump is then activated, discharging air into the water and sediment area through the oxygenation pipe 6 and the exhaust head 7 to begin oxygenation. The drive motor 10 is then activated, driving the first and second agitators 14 and 16 to reciprocate via a gear transmission mechanism, continuously agitating the sediment. This allows pollutants in the sediment to be fully released into the water, while simultaneously allowing air to mix more thoroughly with the sediment and water. The cover 4 confines the agitated sediment and water within its internal area, enhancing the oxygenation effect. After completing the sediment restoration work in this area, the vessel 1 is moved to the next area to be restored. The above operations are repeated to complete the sediment ecological restoration and oxygenation purification work for the entire wetland. After the work is completed, the cover 4 is raised using the lifting assembly, and the equipment is transferred.
