Description

Technical Field

[0001] This invention relates to the field of water environment management technology, specifically a combined ecological restoration device for watershed water environment management. Background Technology

[0002] Due to pollution and severe ecosystem degradation, river water quality has largely reached Class I or worse. Many rivers are severely polluted, eutrophic, blackened, foul-smelling, and contaminated with pathogens, creating a serious environmental and ecological situation that severely impacts the ecological, production, and living safety of urban and rural areas. With increasing demands for environmental protection, various methods have been developed for river water environment management and restoration, including aeration systems, floating islands, artificial reefs, and fish nests. Aeration systems primarily improve the river water environment by laying pipelines in the water area and releasing air into the water through aeration discs, increasing the oxygen content of wastewater during treatment. Furthermore, aeration systems can be integrated with floating islands, artificial reefs, and fish nests to enhance the overall restoration of the aquatic ecosystem. Various man-made structures, combined with aquatic plants and specific organisms, can effectively purify water bodies physically, improving and restoring the ecological environment of the waterways.

[0003] Currently, ecological restoration equipment used for water environment management requires electricity to supply air, and the aeration system is relatively complex, with a high failure rate and high maintenance costs. Furthermore, it cannot raise specific fish populations to purify water quality according to needs. Summary of the Invention

[0020] (III) Beneficial Effects

[0021] Compared with existing technologies, the present invention provides a combined ecological restoration device for watershed water environment management, which has the following beneficial effects:

[0022] 1. In use, multiple plant racks can be arranged in the same number to form multiple groups until a suitable width is reached. The two ends are sealed with retaining walls and tail weirs to form a water-blocking dam structure. Under the action of the water-blocking dam structure, a certain water level difference is formed between the upstream and downstream. After the water level rises, it first enters the planting rack from the channel opening. After the water level in the planting rack rises, it overflows into the water storage channel. After the water level in the water storage channel rises, it is discharged downstream from the overflow outlet on the tail weir. In this way, the water level is raised by interception, and the water flow can be divided into thin streams during the overflow process. When the water flow falls, it can also impact the low water surface, increasing the contact area and time with air. The hinge components set in the plant rack can form a multi-layer structure inside. When arranged in a row, multiple channels can be formed, thus forming multiple spaces inside for planting emergent plants, submerged plants, and underwater plants. The space in the middle can be selected as a breeding area, and the size of the breeding area can be adjusted according to needs to raise more fish.

[0023] 2. The hinged assembly of this invention allows for the synchronous folding of two gantry frames via two meshing arc-shaped racks. This synchronous folding ensures the parallel movement of the two side plates. During installation, the lower end of the side plates is inserted into the riverbed mud, and the tight fit of the folded edges allows multiple plant frames to form a relatively sealed space. The aperture of the mesh plate can be selected according to requirements; in particular, small-aperture mesh plates can be selected for aquaculture areas to isolate fish eggs from the outside environment, ensuring that water only overflows into the storage channel from the top. Multiple triangular openings during the overflow process create multiple fine streams, and the overflow outlet is positioned lower than the triangular openings. This allows the fine streams after being diverted by the triangular openings to impact the water in the storage channel, generating air bubbles and increasing the oxygen content in the water. After assembly, the U-shaped clips not only fix the water-dividing plate in the limiting slot but also connect and fix it to adjacent side plates via the U-shaped groove, positioning groove, and positioning unit.

[0024] 3. The turbulence-inducing mechanism of this invention, during use, ensures that the upstream water flow can only overflow due to the dam formed by the retaining wall and tail weir. Therefore, the downstream water level is much lower than the upstream water level, thus creating a level difference. Part of the water in the reservoir is discharged through the overflow outlet. Under the action of gravity, the water flows quantitatively through the drain pipe and the constriction section, resulting in a water flow with a flow velocity. When the water flows, it drives the first impeller and the second impeller to rotate. When the first impeller rotates, it drives the hollow shaft to rotate the cage. When the cage rotates, it drives the triangular plate to make a circular motion. At this time, the triangular plate can be used to stir the water flow at the overflow nozzle, so that the water flow forms a vortex at the overflow nozzle. This allows the water to be further stirred during overflow, increasing the contact with air. In addition, when the second impeller rotates, it drives the vertical shaft to rotate the pump wheel. When the pump wheel rotates, it pushes the water in the flow-limiting pipe upward and accelerates its discharge. At this time, some water can be pushed into the air. Under the action of gravity, the water falls freely and hits the water surface, forming small bubbles in the water. This allows the water to be further dispersed by turbulence during the movement, fully contacting the air. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1: Refer to Appendix Figures 1-14 A combined ecological restoration device for watershed water environment management includes a retaining wall 1, a tail weir 5, and multiple sets of plant racks. The plant racks are evenly arranged between the retaining wall 1 and the tail weir 5 to form multiple water storage channels. Each plant rack includes two side plates 17, symmetrically arranged. Each side plate 17 has a flange 16 at both opposite ends, and positioning holes are provided at each flange 16. An internally threaded sleeve 29 is provided between the two side plates 17, containing two sections of internally threaded threads in opposite directions. There are two screws 30 connected by internal threads. The opposite ends of the two screws are fixedly connected to ear seats. Two pull rods 18 are rotatably connected in the ear seats by pins. The ends of the two pull rods 18 away from the pins are fixedly connected to positioning pins 27. The side wall of the positioning pin 27 is sleeved in the positioning hole and has a groove 28. Multiple hinge components are provided in the planting frame. Multiple channel openings 3 are opened at the upper end of the retaining wall 1 and the channel openings 3 are connected to the plant frame. Multiple overflow outlets are opened at the upper end of the tail weir 5 and the overflow outlets are connected to the water storage channel.

[0042] The retaining wall 1 is composed of multiple baffles, each with a right-angle notch at its corner. The right-angle notches on two adjacent baffles together form the channel opening 3. The tail weir 5 is composed of multiple tail plates, each with a notch at its upper end. The notches on two adjacent tail plates together form the overflow outlet. Multiple I-beams 2 are fixedly connected to the side walls of both the retaining wall 1 and the tail weir 5. Two I-beams 2 are symmetrically arranged on one side of each baffle of the retaining wall 1. One I-beam 2 is arranged at the joint between two adjacent tail plates of the tail weir 5. Multiple shells 10 are provided on one side of the tail weir 5. Each shell 10 contains a flow-turbulence component, which is fixed to one side of the tail plate. The flow-turbulence component converts the water level difference in the reservoir into mechanical energy, and uses the mechanical energy to agitate the water discharged from the overflow outlet so that it can fully contact the air and achieve aeration.

[0043] When in use, multiple plant racks can be arranged in the same number of groups until a suitable width is reached. The two ends are sealed relative to each other using retaining walls 1 and tail weirs 5, thus forming a water-retaining dam structure. The width of the water-retaining dam structure matches the width of the water surface, so that water can only overflow through the upper end of the water-dividing plate 4. Under the action of the water-retaining dam structure, a certain water level difference is formed between the upstream and downstream. After the water level rises, it first enters the plant rack from the channel opening 3. After the water level in the plant rack rises, it overflows into the water storage channel. After the water level in the water storage channel rises, it is discharged downstream from the overflow outlet on the tail weir 5. In this way, the water level is raised by interception, and the water flow can be divided into a thin stream during the overflow process. When the water flow falls, it can also impact the low water surface, increasing the contact area and time with the air.

[0044] like Figure 2As shown, the hinged components inside the plant rack can form a multi-layered structure. When arranged in a row, multiple channels can be formed, thus creating multiple spaces inside for planting emergent plants, submerged plants, and other aquatic plants. The space in the middle can be selected as a breeding area, and the size of the breeding area can be adjusted according to needs to raise more fish, such as plecos. Plecos are omnivorous fish that feed on algae, benthic animals, and debris in the water.

[0045] Example 2: The difference from Example 1 is that;

[0046] See attached document Figure 2 and Figure 3 The hinge assembly includes a center plate 20 and two gantry frames 21. Two rectangular plates are fixedly connected to the lower end of the center plate 20. Both ends of the two gantry frames 21 are fixedly connected to connecting blocks 26 at an angle. The sidewalls of the connecting blocks 26 are rotatably connected to the sidewalls of the rectangular plates through connecting shafts. The ends of the two connecting blocks 26 are fixedly connected to arc-shaped racks 25, which mesh with each other. The end of the gantry frame 21 away from the connecting blocks 26 is rotatably connected to the two folded edges 16 of the side plate 17 through pins. A perforated plate 22 is fixedly connected inside the gantry frame 21. Inclined plates 23 are fixedly connected to the opposite sides of the center plate 20. The inclined plates 23 are in contact with the sidewalls of the perforated plate 22. The multiple hinge assemblies divide the interior of the planting rack into emergent plant planting area, submerged plant planting area, aquaculture area and submerged plant planting area from top to bottom.

[0047] Limiting plates 12 are fixedly connected to opposite sides of the two folded edges 16. The limiting plates 12 and one side of the side plate 17 form a limiting groove. The side plate 17 is clamped to the water-dividing plate 4 through the limiting groove. The upper end of the water-dividing plate 4 is provided with a bent part. Multiple triangular openings 15 are provided at the edge of the bent part. Multiple evenly distributed through holes are provided on the side wall of the water-dividing plate 4. The upper ends of the limiting plates 12 and the side plate 17 are provided with U-shaped grooves 13. The upper end of the folded edges 16 is provided with positioning grooves 14. A positioning part 19 is provided on one side of the positioning groove 14. A U-shaped clip 11 is clamped in the positioning part 19. The two parallel parts of the U-shaped clip 11 are respectively located in the U-shaped grooves 13 on the two adjacent side plates 17. The water-dividing plate 4 is sleeved with the U-shaped clip 11 through the through holes.

[0048] The hinge assembly of this invention allows for the synchronous folding of two gantry frames 21 via two meshing arc-shaped racks 25. This synchronous folding ensures the parallel movement of the two side plates 17. During installation, the lower ends of the side plates 17 are inserted into the riverbed mud, and the tight fit of the folded edges 16 allows multiple plant supports to form a relatively sealed space. Furthermore, the aperture of the mesh plate 22 can be selected according to requirements; in particular, smaller aperture mesh plates can be selected for the aquaculture area to isolate fish eggs produced within the aquaculture area from the outside environment. The water flow can only overflow into the storage channel from the top. During the overflow process, multiple triangular openings 15 can form multiple thin streams of water. The position of the overflow outlet is lower than the position of the triangular openings 15. This allows the thin streams after being diverted by the triangular openings 15 to impact the surface in the storage channel and generate bubbles, thereby increasing the oxygen content in the water. After assembly, the U-shaped clips 11 can not only fix the water distribution plate 4 in the limiting slot, but also connect and fix it to the adjacent side plates 17 through the U-shaped groove 13, the positioning groove 14 and the positioning part 19.

[0049] Example 3: The difference from Example 1 is that;

[0050] See attached document Figure 8-14 The turbulence-inducing assembly includes two drain pipes 32. One end of each drain pipe 32 is fixedly connected to the side wall of the enclosure, and the other end of each drain pipe 32 is located at the constriction portion 9. The opposite sides of the housing 10 are fixedly connected to the side wall of the constriction portion 9 via connecting ports. One side of the constriction portion 9 is located inside the housing 10 and has an arc-shaped opening 24. The center of the arc-shaped opening 24 is located on the center line of the housing 10. A partition 36 is fixedly connected inside the housing 10. A hollow shaft 7 is rotatably connected to the center of the partition 36 via a sealed bearing. An end cap 8 is rotatably connected to the shaft wall of the hollow shaft 7 via a sealed bearing. The end cap 8 is fixed to the upper end of the housing 10. The shaft of the hollow shaft 7... A first impeller 34 is fixedly connected to the wall. The upper end of the hollow shaft 7 is rotatably connected to the outer shell 40 through a sealed bearing. An overflow nozzle 6 is fixedly connected to the side wall of the outer shell 40. The overflow nozzle 6 is fixed at the overflow port. Two U-shaped pieces 43 are fixedly connected to one side of the overflow nozzle 6. The two U-shaped pieces 43 form a snap-fit ​​groove, which snaps into the overflow port. The side wall of one of the U-shaped pieces 43 is fixedly connected to the side wall of the tail plate by bolts. A retainer 38 is provided inside the outer shell 40. Multiple water inlets are opened on the side wall of the retainer 38. Multiple evenly distributed triangular plates 39 are fixedly connected inside the retainer 38. Multiple slits are opened on the side wall of the triangular plates 39.

[0051] A vertical shaft 31 is rotatably connected inside the hollow shaft 7 via a sealed bearing. The lower end of the vertical shaft 31 extends into the housing 10 and is fixedly connected to a second impeller 33, which is the same as the first impeller 34. The upper end of the vertical shaft 31 extends into the retainer 38 and is fixedly spliced ​​with a pump wheel 41. A flow-limiting tube 37 is sleeved on the side wall of the pump wheel 41. Multiple blades 42 are fixedly connected to the lower end of the flow-limiting tube 37 at an incline. The lower ends of the multiple blades 42 are all fixedly connected to the lower end of the retainer 38. Two symmetrically distributed flow guides 35 are provided on the side walls of the first impeller 34 and the second impeller 33. The multiple flow guides 35 are fixed inside the housing 10 to form two annular channels. The two annular channels are respectively matched with the arc-shaped openings 24 on the two nozzles 9.

[0052] The flow-dissipating mechanism of this invention, during use, ensures that the upstream water flow can only overflow due to the dam formed by the retaining wall 1 and the tail weir 5. Therefore, the downstream water level is significantly lower than the upstream water level, creating a level difference. A portion of the water in the storage channel is discharged through the overflow outlet. Under the influence of gravity, the water flows quantitatively through the drain pipe 32 and the constriction section 9, resulting in a flow with a specific velocity. The flowing water drives the first impeller 34 and the second impeller 33 to rotate. The rotation of the first impeller 34 drives the hollow shaft 7, causing the retainer 38 to rotate. The rotation of the retainer 38 then drives the triangular plate 39. When the water is moving in a circular motion, the triangular plate 39 can be used to agitate the water flow at the overflow nozzle 6, causing the water to form a vortex at the overflow nozzle 6. This further agitates the water during overflow, increasing its contact with the air. In addition, when the second impeller 33 rotates, it drives the vertical shaft 31 to rotate the pump wheel 41. When the pump wheel 41 rotates, it pushes the water in the flow limiting pipe 37 upward and accelerates its discharge. At this time, some water can be pushed into the air. Under the action of gravity, the water falls freely and hits the water surface, forming small bubbles in the water. This allows the water to be further turbulent and dispersed during the movement, ensuring sufficient contact with the air.
