[0002] As crucial vehicles for the natural water cycle, the ecological health of rivers is directly linked to flood control, water quality, and biodiversity. However, due to natural erosion, human development (such as embankment hardening and excessive sand mining), and vegetation destruction, most rivers around the world face severe soil erosion.

[0005] In the above technical solution, further, the water-turning assembly includes a rotating shaft rotatably arranged inside the water storage grid, a sleeve is fixedly sleeved on the middle of the outside of the rotating shaft, and water-turning buckets are installed on the outer surface of the sleeve at equal distances along the circumferential direction. One end of the rotating shaft passes through the outside of the water storage grid and a crank is installed on the end.

[0006] In the above technical solution, further, the water control component includes a reserved opening opened in the diversion box and facing the inside of the water storage grid, and the position of the reserved opening corresponds to the position of the water bucket, and a discharge opening is installed inside the diversion box on the side away from the reserved opening, and a valve is installed inside the discharge opening.

[0007] In the above technical solution, further, an elastic ring is clamped in the middle of the corrosion-resistant filter screen, and supporting cartilage is installed on the elastic ring at equal distances along the circumferential direction. The bottom of the supporting cartilage fits the corrosion-resistant filter screen, and a clamping shaft is rotatably installed on the end of the supporting cartilage away from the elastic ring. A mounting block is mounted on the outside of the clamping shaft, and grooves are provided inside the ring strip and near the mounting block, and the mounting block is fixedly filled in the groove.

[0008] In the above technical solution, further, the corrosion-resistant filter screen is arranged in a conical shape and has multiple groups of filter holes on the outer surface, and scrapers are installed on the inner surface of the corrosion-resistant filter screen at equal distances along the circumferential direction.

[0009] In the above technical solution, further, both sides of the outside of the ring bar are fixedly connected with fixed blocks, the outside of the slope fixing shell and the corresponding positions of the fixed blocks are fixedly connected with positioning blocks, and a fixing pin is movably inserted into the inside of the fixed block, and the lower end of the fixing pin extends to the inside of the positioning block.

[0010] In the above technical solution, further, overflow holes are opened at equal distances in the horizontal direction on one side of the interior of the irrigation pipe and near the slope fixing shell, and drainage holes are opened at equal distances in the circumferential direction at the lower part of the slope fixing shell.

[0011] In the above technical solution, further, a filter plate is installed above the water storage grid, and the filter plate has filter grooves equidistantly opened in the horizontal direction. A card plate is movably installed above the guide box, and a pull rod is installed on the upper surface of the card plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. The water storage grid at the top of the slope is an open structure, which can naturally collect rainwater, slope runoff and river overflow water. Before entering the water storage grid, the rainwater is first filtered by the filter groove of the filter plate to intercept impurities such as dead branches and stones, avoid subsequent flow channel blockage, and reserve water for irrigation during drought periods. When irrigation or drainage is needed, the shaft is driven to rotate by manually turning the crank handle, which drives the water bucket outside the ferrule to rotate synchronously. The inner cavity of the water bucket is arc-shaped, and it scoops water from the water storage grid as the shaft rotates. After rotating to the highest point, the water is poured into the reserved opening of the diversion box.

[0013] The water control assembly within the diversion box regulates flow through a valve. When the valve is open, water flows through the outlet and into the overflow pipe. When the valve is closed, water supply is suspended to meet the water needs of different plants. This design requires no electricity, enabling flexible water supply through manual operation, eliminating reliance on professional maintenance and addressing the power and maintenance challenges of traditional equipment.

[0014] 2. The overflow pipe and irrigation pipe are set up to encourage the water entering the overflow pipe to flow downward along the slope surface and be diverted to the irrigation pipe through multiple groups of flow channels on both sides of the pipe. The irrigation pipe is horizontally distributed along the outer side of the slope-fixing shell, and an overflow hole is opened on the side facing the slope-fixing shell. Water flows evenly from the overflow hole to directly irrigate the vegetation at the planting port in the slope-fixing shell, solving the problem of uneven irrigation of traditional sprinkler heads.

[0015] Excess water is discharged through the drainage holes at the bottom of the slope-fixing shell to avoid water accumulation and root rot of plants. At the same time, drainage can take away a small amount of surface fine soil, which is intercepted by the filter and retained in the slope-fixing shell, further enhancing soil fertility.

[0016] 3. The slope-fixing shell is a double-layer structure. The ring bar is locked with the slope-fixing shell through a fixing block, a positioning block and a fixing pin, so that the corrosion-resistant filter screen is firmly fixed on the slope surface. The filter screen is conical, and the filter holes on its outer surface can intercept soil particles, allowing water to penetrate, preventing rainwater from directly washing the slope surface and causing soil erosion. The planting port in the middle of the corrosion-resistant filter screen is used to plant herbs or shrubs. The plant roots penetrate through the filter holes and penetrate into the slope soil, forming a "filter screen covering the roots" composite soil-fixing structure. The elastic ring and supporting cartilage inside the filter screen are flexible structures (the supporting cartilage is made of high-density polyethylene), which can expand outward as the plant grows to avoid squeezing the root system; when the soil inside the slope-fixing shell is uneven, the soil can be leveled by sliding the scraping bars and ring bars on the inner surface during the filling period.

[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1-8The ecological slope protection module for urban river management and restoration shown in the figure includes a slope body 1, a water storage grid 2 is set at the top of the slope body 1, a water turning component is set inside the water storage grid 2, the surface of the slope body 1 is set in an inclined plane, and an overflow pipe 4 is set on the slope surface of the slope body 1, a guide box 34 is set above the overflow pipe 4, and a water control component is set inside the guide box 34. Multiple groups of flow channels 28 are opened on both sides of the overflow pipe 4, and the flow channels 28 are connected to the irrigation pipe 5. The slope body 1 is on the slope surface and close to the two overflow pipes 4. A slope-fixing shell 6 is symmetrically arranged between them. The interior of the slope-fixing shell 6 is double-layered and has a sliding cavity 25. A connecting rod 23 is symmetrically arranged inside the sliding cavity 25. A rotating sleeve 24 is sleeved on the outside of the connecting rod 23. The rotating sleeve 24 is slidably connected to the sliding cavity 25. A ring strip 13 is commonly provided on the upper end of the connecting rod 23. A corrosion-resistant filter screen 9 is clamped on the outside of the ring strip 13, and a planting port is opened in the middle of the corrosion-resistant filter screen 9. A filter plate 3 is installed above the interior of the water storage grid 2, and the filter plate 3 has filter slots 31 equidistantly opened in the horizontal direction. As the instruction manual Figure 1-Figure 3 As shown, the slope 1 is a natural slope of the river channel, which is arranged in an inclined plane with a slope of 15°-30°. The water storage grid 2 is a rectangular open structure, arranged on the top of the slope, and is made of concrete. A water storage cavity is provided inside the water storage grid 2 for collecting rainwater. A filter plate 3 is fixedly installed on the upper part of the water storage grid 2 by external bolts. The filter groove 31 provided inside the filter plate 3 is used to intercept dead branches and larger stones to avoid blockage of the subsequent flow channel 28.

[0022] The water turning assembly includes a rotating shaft 10 rotatably arranged inside the water storage grid 2, a clamping sleeve 30 is fixedly sleeved on the middle of the rotating shaft 10, and water turning buckets 35 are installed on the outer surface of the clamping sleeve 30 at equal intervals along the circumferential direction. One end of the rotating shaft 10 passes through the outside of the water storage grid 2 and a crank 8 is installed at the end; The water control assembly includes a reserved opening 12 opened in the diversion box 34 and facing the inside of the water storage grid 2, and the position of the reserved opening 12 corresponds to the position of the water tipping bucket 35. A discharge port 29 is installed inside the diversion box 34 on the side away from the reserved opening 12, and a valve 32 is installed inside the discharge port 29. A card plate 7 is movably mounted on the upper surface of the diversion box 34, and a pull rod 33 is installed on the upper surface of the card plate 7. As the instruction manual Figure 2 and Figure 3As shown, when the water storage grid 2 is replenished with water, the crank 8 is turned to drive the rotating shaft 10 to rotate, causing the water bucket 35 to rotate. The arc-shaped cavity inside the water bucket 35 can scoop the water of the water storage grid 2 to the reserved opening 12 (the arc-shaped inner wall and the edge of the water bucket 35 form a 1-2 cm fold to prevent leakage during the scooping process; the horizontal height of the reserved opening 12 is lower than the bottom height of the water bucket 35 when it rotates to the highest point, and the horizontal distance between the two does not exceed 5 mm to ensure that the water flow is fully introduced). The interior of 34 is a hollow structure, fixed to one side of the water storage grid 2 and close to the side of the slope 1. The reserved opening 12 is a rectangular opening (the size matches the water bucket 35, and the position corresponds to the water outlet position when the water bucket 35 rotates to the highest point), ensuring that the water bucket 35 can pour all the poured water into the diversion box 34, and by opening the valve 32, it is used to regulate the flow rate. In addition, the card plate 7 on the upper part of the diversion box 34 can be movably removed to facilitate cleaning impurities inside the diversion box 34 and opening the valve 32.

[0023] An elastic ring 14 is mounted in the middle of the corrosion-resistant filter 9, and supporting cartilage 15 is mounted on the elastic ring 14 at equal distances along the circumferential direction. The bottom of the supporting cartilage 15 fits the corrosion-resistant filter 9, and the end of the supporting cartilage 15 away from the elastic ring 14 is rotatably mounted with a card shaft 22. A mounting block 20 is sleeved on the outside of the card shaft 22. A notch 26 is provided inside the ring strip 13 and close to the mounting block 20. The mounting block 20 is fixedly filled in the notch 26. The corrosion-resistant filter 9 is conically arranged and has multiple groups of filter holes 27 on its outer surface. A scraper strip 21 is mounted on the inner surface of the corrosion-resistant filter 9 at equal distances along the circumferential direction. The outer sides of the ring strip 13 are fixedly connected with fixed blocks 19, and the outer sides of the slope fixing shell 6 and the positions corresponding to the fixed blocks 19 are fixedly connected with positioning blocks 18. The fixing blocks 19 are movably inserted with fixing pins 17, and the lower ends of the fixing pins 17 extend into the interior of the positioning blocks 18. As the instruction manual Figure 3-Figure 8 As shown, the ring strip 13 is a stainless steel ring, which is fixedly connected to the upper ends of the two connecting rods 23 (by welding) and is used to install the corrosion-resistant filter screen 9. The fixing block 19 outside the ring strip 13 and the positioning block 18 are both provided with corresponding through holes, and the through holes can be movably inserted with a fixing pin 17 to lock the ring strip 13 and the slope-fixing shell 6. The planting port opened in the middle of the corrosion-resistant filter screen 9 can be used for planting plants. The elastic ring 14 in the middle is made of rubber material, and the supporting cartilage 15 arranged around the elastic ring 14 is made of polyethylene material. The supporting cartilage 15 can make the corrosion-resistant filter screen 9 more three-dimensional and fit the planting soil. At the same time, the flexible structure is suitable for the natural growth of plants, and can intercept the planting soil to avoid soil erosion. When filling the soil, by removing the fixing pin 17 and rotating the ring strip 13, the scraper 21 on the inner surface of the corrosion-resistant filter screen 9 can be evenly scraped to level the soil, ensuring uniform soil distribution.

[0024] Overflow holes 11 are opened at equal intervals in the horizontal direction on one side of the inner part of the irrigation pipe 5 and near the slope fixing shell 6, and drainage holes 16 are opened at equal intervals in the circumferential direction on the lower part of the slope fixing shell 6; As the instruction manual Figure 1 and Figure 2 As shown, the flow channel 28 inside the overflow pipe 4 can be used to connect the irrigation pipes 5 of each passage. During drainage, after water enters each flow channel 28, the water is sprayed out through the overflow hole 11 to directly irrigate the vegetation, and the excess water inside the slope-fixing shell 6 is discharged again through the drainage hole 16.

[0025] The above design realizes the functions of efficient use of rainwater, non-electrically driven irrigation, uniform water supply and strong slope consolidation and water loss prevention, effectively solving the problems of existing technologies such as dependence on electricity, difficult maintenance, uneven irrigation and insufficient soil and water loss control.

[0026] Working principle: the water storage grid 2 at the top of the slope 1 is an open water collection structure, which can naturally receive rainwater. Before the rainwater enters the water storage grid 2, it is first filtered by the filter groove 31 (width 5-8mm) of the filter plate 3 to intercept large particles of impurities such as dead branches and stones, avoid clogging of the subsequent flow channel 28, and reserve water for subsequent vegetation irrigation during drought periods, solving the problem of "low rainwater utilization rate" of traditional slope protection. When irrigation or water level adjustment is needed, the rotating shaft 10 is driven to rotate by manually turning the crank 8, driving the arc-shaped structure of the water bucket 35 outside the ferrule 30 to rotate synchronously. The water bucket 35 scoops the water in the water storage grid 2 as the rotating shaft 10 rotates. After rising to the highest point, it is accurately poured into the reserved port 12 of the diversion box 34 corresponding to the position of the water bucket 35 to ensure that there is no leakage of water. The water control component in the diversion box 34 realizes flow regulation through the valve 32. When the valve 32 is opened, the water enters the overflow pipe 4 through the discharge port 29; when the valve 32 is closed, the water supply can be suspended. Water, this design does not require electric drive, and achieves flexible water supply through a purely mechanical structure, avoiding the defects of traditional equipment "dependence on electricity and need for professional maintenance", and adapts to the wild environment of rivers. The water entering the overflow pipe 4 flows downward along the slope and is diverted to the horizontally distributed irrigation pipe 5 through multiple groups of flow channels 28 on both sides of the pipe. The irrigation pipe 5 is provided with an overflow hole 11 on the side facing the slope-fixing shell 6. The water is sprayed out from the overflow hole 11 in a scattered manner to directly irrigate the vegetation (such as calamus, bermudagrass and other native plants) at the planting opening in the slope-fixing shell 6, solving the problem of "uneven irrigation and poor effect" of traditional sprinkler heads. The water entering the overflow pipe 4 flows downward along the slope, and the excess water is discharged through the drainage hole 16 on the lower inner side of the slope-fixing shell 6, avoiding water accumulation and root rot of plants. A small amount of surface fine soil carried during drainage is intercepted by the corrosion-resistant filter screen 9 and retained in the slope-fixing shell 6, which can enhance soil fertility and form a virtuous cycle of "irrigation-drainage-fertilization"; The slope-fixing shell 6 is a double-layer hollow structure. The rotating sleeve 24 in the internal sliding cavity 25 can slide along the connecting rod 23. The ring bar 13 is locked with the slope-fixing shell 6 through the fixing block 19, the positioning block 18 and the fixing pin 17, and the corrosion-resistant filter 9 is firmly fixed on the slope. The corrosion-resistant filter 9 is conical, and the filter holes 27 on the outer surface can intercept soil particles, allowing water to penetrate, directly blocking rainwater from eroding the slope, and reducing soil and water loss. The planting port in the middle of the corrosion-resistant filter 9 is used for planting plants. The roots penetrate the filter holes 27 and penetrate into the soil of the slope 1, forming a "corrosion-resistant filter 9-root system" composite. The soil-solidifying structure and the corrosion-resistant filter screen 9 intercept the loose soil on the surface, and the roots are anchored in the deep soil. The elastic ring 14 and the supporting cartilage 15 inside the corrosion-resistant filter screen 9 are both flexible structures, which can expand outward with the growth of the plants to avoid squeezing the roots. The scraper 21 on the inner surface can evenly distribute the soil when manually moved, and the distribution of the soil can be guaranteed during the later filling. Through the above mechanism, the module realizes the integrated functions of rainwater resource utilization, precise vegetation maintenance, slope maintenance, and ecological restoration, effectively solving the problem of soil erosion on the river slope and improving the stability of the ecosystem.
