DETAILED DESCRIPTION

[0024] The following is combined with Figures 1-5 This application is described in further detail.

[0025] Example 1 A prefabricated shoreline ecological filtration device for enhancing water clarity comprises a frame structure, a filter assembly 1, and a connecting structure. A hollowed-out area is formed within the frame of the assembly frame 11, reducing structural weight and allowing water to flow more efficiently through the filter assembly 1, while also facilitating the device's integration into the aquatic environment. The filter assembly 1 is positioned within the hollowed-out area for water filtration. In actual use, the filter assembly 1 can be configured with different materials or filter media to adjust the treatment effect according to water quality requirements. The connecting structure, located on either side of the assembly frame 11, includes at least two compatible connecting components. The connecting structure allows adjacent frames to be removably connected, facilitating rapid assembly and disassembly. This enhances the device's flexibility and allows for expansion or reduction as needed. Multiple frames are connected together to form a filtration device that covers the entire shoreline. This layout ensures effective water filtration and ecological restoration throughout the entire shoreline, enhancing water clarity and quality.

[0026] The connection structure includes an assembly clip 13 and a mounting clip 14. The assembly clip 13 is located on one side of the assembly frame 11 and forms an integrated structure with the assembly frame 11. This integrated design avoids the need for separate connections of multiple components and enhances the stability of the structure. The assembly clip 13 facilitates connection with adjacent frames, provides higher docking accuracy, ensures a tight fit during assembly, and prevents loosening of the joints. The mounting clip 14 is located on the other side of the assembly frame 11. Its size matches that of the assembly clip 13, allowing for precise mating and connection. The mounting clip 14 and the assembly frame 11 are also integrated, further enhancing the integrity and stability of the device and preventing loosening or detachment of external connectors. Through the coordination of the assembly clip 13 and the mounting clip 14, two adjacent assembly frames 11 can be securely connected, with a certain degree of removability. This design not only facilitates installation and disassembly but also allows for flexible expansion and adjustment as needed.

[0027] In the above embodiment, further, Figure 2As shown, the assembly edge 13 is provided with a plurality of assembly holes 15. The number and arrangement of the assembly holes 15 can be adjusted according to the slope inclination and the required length to provide multiple connection points, thereby enhancing the stability and balance of the connection. The mounting edge 14 is provided with an assembly pin 16 whose shape and size match the assembly holes 15. The design of the assembly pin 16 enables the mounting edge 14 to securely dock with the assembly holes 15 on the assembly edge 13, thereby achieving precise docking. The function of the assembly pin 16 is to ensure a tight connection between the assembly edge 13 and the mounting edge 14 by inserting into the assembly holes 15, preventing the connection from loosening due to water flow or external forces. The coordination between the assembly holes 15 and the assembly pin 16 enables a fixed connection between adjacent frames, ensuring accurate connection positions and preventing positional deviation or loose connections during use. This fixed connection makes the device more stable, capable of withstanding large external pressures or water impacts, and meeting long-term water filtration needs.

[0028] In the above embodiment, if Figure 4 As shown, an assembly sealing strip 17 is provided on the edge of the mounting clamp 14. The assembly sealing strip 17 is a sealing component, which further optimizes the connection structure of the assembled shore ecological filtration device for improving water transparency, ensures the sealing of the connection between adjacent frames, prevents water leakage or diffusion of pollutants, and improves the overall efficiency and durability of the device. At the connection between the assembly frames 11, the sealing component fills the tiny gaps between the connectors to prevent water from leaking through the connection parts. This design is especially important for devices that are exposed to water for a long time, because preventing water leakage and diffusion of pollutants helps to improve the water filtration effect.

[0029] In the above embodiment, further, Figure 4 As shown, the bank clip 18 is located at the short side where the assembly frame 11 contacts the bank, with the purpose of ensuring that the assembly frame 11 can be firmly installed on the edge of the bank. The function of the bank clip 18 is to achieve a limiting function through contact with the bank, so that the assembly frame 11 can be fixed in a predetermined position when installed in the shore zone, preventing the frame from being displaced due to water flow, waves or external forces. The bank clip 18 ensures that the assembly frame 11 will not move along the bank or deviate from the predetermined position through contact with the bank, especially in the case of large water flow or tidal changes. The limiting function ensures the long-term stability of the device, so that the assembly frame 11 always remains in the best position, ensuring the continued performance of the filtering effect and ecological restoration function.

[0030] In actual use, Figure 1 or Figure 5As shown, the edge of the revetment is sloped at a certain angle or vertical, and the water body passes through the filter component 1 into the obtuse triangle area or right-angled triangle area formed inside for water collection and drainage, and enters the inner water collection area and drainage area through the filter screen cover 12. By filling the filter filler inside the filter screen cover 12, the filtration performance is further improved. According to the length of the revetment, the assembly frame 11 is combined to form a complete filtration area. The filtration is mainly divided into the filter material area, the water collection area, the drainage area, the drainage pump and the pipeline. The river water flows downward along the filter material area, and after being adsorbed, filtered and purified by the filter material, it enters the water collection area. Pipelines and water pumps are arranged in the water collection area, and the clean water in the water collection area is pumped into the river by the water pump.

[0031] During the actual filtration process, the filter screen 12 purifies the water through both physical filtration and retention by the filter material and degradation by microorganisms attached to the material. Physical retention removes suspended matter from the water. The accumulation of filter material within the filtration area increases the contact area between the water and particles, facilitating the attachment of microorganisms to the material surface. These microbial metabolic processes further degrade and absorb water pollutants. Furthermore, aquatic plants can be planted within the filter material, where their roots further absorb nutrients such as nitrogen and phosphorus from the water, improving water quality. The ecological filter material has pores between it, and during contact between the river water and the material particles, microorganisms continuously attach to the material surface. Natural microorganisms adhere to the material surface. Microorganisms are one of the primary degraders of organic matter in water. Through metabolic processes, they break down organic waste into simpler compounds, helping to purify the water and remove suspended particles and pollutants. Furthermore, to enhance purification effectiveness, microorganisms can be added to the filter material. A nitrifying-denitrifying bacterial complex can be added to the filter material to enhance purification.

[0032] Example 2 On the basis of Example 1, in order to meet the overall assembly and use requirements, the system functions of the assembled coastal zone ecological filtration and water transparency enhancement device are further improved to make water filtration and water flow management more efficient. Pipe assembly units are added to the filtration area to meet the overall assembly flexibility.

[0033] like Figure 6As shown, the pipeline assembly unit includes: assembly pipeline 2, pipeline connector 3 and assembly part 4, the assembly pipeline 2 is responsible for transporting water flow, sewage or treated water. According to the actual use requirements, the diameter and length of the assembly pipeline 2 can be different, to adapt to the needs of different flow and flow rate. Both ends of the assembly pipeline 2 are provided with pipeline connector 3, which is used to realize the connection between pipeline and pipeline, pipeline and other components (such as water pump, filter), to ensure the smooth flow of water. The pipeline connector 3 between adjacent assembly pipeline 2 is connected and fixed by assembly part 4, to ensure the overall stability and sealing of the pipeline assembly unit. The assembly pipeline 2 is a hollow tubular structure, mainly used for conveying purified water in the water collection area of the filter assembly, its diameter is designed according to the daily average water output of the filter area, to ensure the smooth flow of water without accumulation.

[0034] As shown in Figure 7 The pipeline connector 3 includes: connecting flange 31, limiting fixed edge 32 and locking through hole 33, the inner diameter of the connecting flange 31 is matched with the outer diameter of the assembly pipeline 2, to ensure the stability of the pipeline connection. The connecting flange 31 is used to connect different pipeline parts, to ensure the sealing and fixed connection. The limiting fixed edge 32 is uniformly distributed along the circumference of the connecting flange 31, which limits the movement of the pipeline and ensures that the position does not deviate during pipeline connection. The locking through hole 33 is provided on the connecting flange 31, which is used to insert bolts or other fasteners, to fix the pipeline connector 3, so that it is not easy to loosen or fall off. The locking through hole 33 also helps to provide a fastening area, to ensure a more secure connection. The limiting fixed edge 32 is tapered along the end of the connecting flange 31, so that the connection between the assembly pipeline 2 and the flange is more tight. The limiting fixed edge 32 is provided with a positioning hole, which is used to assist the butt joint and positioning of the pipeline.

[0035] The assembly part 4 includes: communication main pipe 41, matching flange 42 and collection pipe 43, the communication main pipe 41 is the core part of the assembly part 4, which is matched with the assembly pipeline 2, to ensure that the fluid can flow efficiently and smoothly. The matching flange 42 is provided at both ends of the communication main pipe 41, which is matched with the size of the connecting flange 31, to ensure that it can be effectively connected with other parts of the pipeline system. The collection pipe 43 is provided at the upper end of the communication main pipe 41, which is mainly used for collecting water in the filter area. In order to effectively collect the fluid in the water body, it may also be used to capture impurities or pollutants, to promote the filtering and purification process.

[0036] The collection pipe 43 of the pipeline assembly unit is vertically inserted into the water collection area of the filter assembly, to collect the clean water after being adsorbed by the filter material and degraded by microorganisms; the clean water enters the assembly pipeline 2 through the communication main pipe 41, and then is transported to the drainage pump by the assembly pipeline 2, and finally flows back to the coastal river, to realize the recycling of the purified water body.

[0037] The assembly part 4 is provided with connecting holes corresponding to the locking holes 33 of the pipeline connecting part 3. The pipeline connecting part 3 and the assembly part 4 are fixed by penetrating the locking holes 33 and the connecting holes with bolts and tightening nuts. Meanwhile, sealing gaskets are arranged between the connecting flange 42 and the connecting flange 31 to enhance the sealing performance of the connection.

[0038] Embodiment 3 On the basis of Embodiment 1 and Embodiment 2, an assembly method of the assembly type coastal zone ecological filter device for improving water transparency is provided, which comprises the following steps: S1, a laser range finder is used to measure the length and slope of the coastal zone revetment (90° for vertical revetment slope and 60°-85° for inclined revetment slope), and a reference line for installing the assembly type filter unit is marked. A horizontal reference line is marked at 30-50 cm above the bottom of the vertical revetment. Positioning points are marked every 1.5-2 m along the slope surface of the inclined revetment to ensure that the adjacent filter units are completely connected after splicing.

[0039] S2, the filter cover 12 is embedded in the hollow area of the assembly frame body 11, and a stainless steel self-tapping screw is used to fix one place every 5 cm along the edge of the filter cover 12, ensuring that the screw is embedded to a depth of not more than 2 / 3 of the thickness of the assembly frame body 11 to prevent penetration of the frame body affecting subsequent connection. The assembly sealing strip 17 is embedded in the outer side groove of the clamping edge 14, and the two ends of the sealing strip are reserved for 5 cm of overlapping length. The overlapping part is bonded with special glue to avoid water leakage from the joint of the sealing strip.

[0040] S3, vertical revetment scenario: the revetment clamping strip 18 of the first filter unit is attached to the revetment reference line, and the revetment clamping strip 18 is fixed to the revetment by expansion bolts; the second filter unit is taken, the assembly hole 15 of the assembly clamping edge 13 is aligned with the assembly pin 16 of the clamping edge 14 of the first unit, and is pushed into the clamping edge to completely attach in the horizontal direction, completing the preliminary positioning.

[0041] Inclined revetment scenario: angle steel supports (model L50x5) are installed at the revetment positioning points, and the revetment clamping strip 18 of the filter unit is connected to the angle steel supports by bolts. When splicing adjacent units, the horizontal instrument is used for calibration to ensure that the obtuse angle triangle area (angle 100°-120°) formed by the filter assembly 1 and the revetment has consistent internal angles, ensuring that the water can flow naturally. If the angle is too small, the water flow is too fast, and the filtration is insufficient; if the angle is too large, the water flow is stagnant and easy to accumulate.

[0042] After splicing the adjacent units, stainless steel bolts are penetrated into the attachment part of the assembly clamping edge 13 and the clamping edge 14, the bolt spacing is consistent with the assembly hole 15 spacing, and the torque value is detected after tightening with a torque wrench (which needs to reach 15-20 N·m) to prevent bolt loosening and unit displacement.

[0043] S4. Align the limiting fixing edge 32 of the pipe connector 3 with the port of the assembly pipe 2, push it in along the axial direction of the pipe until the connecting flange 31 fits with the end face of the pipe, fix the connecting flange 31 and the assembly pipe 2 by argon arc welding, take the connecting main pipe 41 of the assembly part 4, align the matching flanges 42 at both ends with the connecting flange 31 of the adjacent assembly pipe 2, so that the connecting hole of the matching flange 42 completely overlaps with the locking through hole 33 of the connecting flange 31; fix it with bolts.

[0044] S5. Connect the end of the connecting main pipe 41 of the pipe assembly unit to the water inlet of the drainage pump through a flexible joint. Connect the drainage pump outlet to the return pipe, and extend the return pipe end into the water body in the coastal zone, forming a complete circuit of "filtration and water collection - pipeline transportation - water return". Turn off the drainage pump and inject clean water into the triangular area of ​​the filter assembly (the water level reaches 1 / 2 of the triangular area height). Let it stand for 30 minutes and observe the connection structure and pipe joints for water seepage. If there are ≤1 water seepage points and the water seepage rate is ≤5mL / h, the seal is considered qualified. If not, readjust the sealing strip or tighten the bolts.

[0045] To test the filtration function, start the drainage pump and inject simulated polluted water (containing 50 mg / L of suspended solids) into the filtration triangle. Run the pump continuously for 2 hours. Collect water samples through the collection pipe 43 every 30 minutes and test the water transparency (which needs to be increased from the initial 30 cm to more than 60 cm) to ensure that the filtration effect meets the standards.

[0046] During the actual assembly process, a 1.2m wide maintenance channel is reserved between every 10 groups of filter units. The pipe assembly units at the channel are connected with detachable flanges to facilitate the later replacement of the filter cover 12 or cleaning of sediment in the pipe.
