DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5, the present utility model provides a technical solution: a modular drainage base structure for highly permeable ecological concrete pavement, including a concrete base 1 and a drainage channel 2 fixedly installed on the side of the concrete base 1. A filter well 3 and a water guide groove 4 are movably clamped inside the drainage channel 2. A cover plate 5 is movably clamped on the top of the water guide groove 4. Drainage holes 6 are opened on the inner side of the drainage channel 2; the filter well 3 includes an upper well ring 31 and a lower well ring 32. Clamping openings 33 are opened inside the upper well ring 31 and the lower well ring 32. Symmetrically arranged clamping rails 34 are fixedly connected to the bottom of the lower well ring 32. A collection basket 35 symmetrically arranged front and back is movably clamped inside the clamping rails 34. A filter frame 36 is movably clamped inside the clamping opening 33. The filter frame 36 is arranged above the collection basket 35. Waste discharge openings one 37 are opened on the front and back sides of the filter frame 36. Waste discharge openings two 38 corresponding to the waste discharge openings one 37 are opened on the front and back sides of the lower well ring 32. When water passes through the filter frame 36, impurities are filtered by the inverted "V" - shaped structure at the bottom and then flow into the drainage channel 2. The design of the filter frame 36 makes impurities flow towards the waste discharge openings one 37 and the waste discharge openings two 38. The collection basket 35 centrally collects impurities and can also secondarily filter the water body, ensuring that the water flowing into the drainage channel 2 has fewer impurities. By dispersing impurities, it prevents the accumulation of impurities inside the filter frame 36, maintains the filtering effect, and reduces the cleaning frequency.

[0024] The waste discharge openings one 37 and the waste discharge openings two 38 coincide, and the waste discharge openings one 37 and the waste discharge openings two 38 are arranged above the collection basket 35, so that the impurities discharged from the filter frame 36 can directly fall into the collection basket 35, avoiding the scattering of impurities during the discharge process. The coincidence setting of the waste discharge openings one 37 and the waste discharge openings two 38 makes the water flow smoother and will not be blocked due to the accumulation of impurities.

[0025] The bottom of the filter frame 36 is arranged in an inverted "V" shape, increasing the filtering area and improving the filtering efficiency. It makes impurities more likely to gather towards the waste discharge opening one 37 along the "V" - shaped bottom under the action of gravity, helping to reduce the resistance of the water body during the filtering process, ensuring unobstructed water flow, and further improving the overall drainage efficiency.

[0026] A bottom edge 39 is arranged on the top of the collection basket 35. The bottom edge 39 abuts against the bottom of the filter frame 36. By pressing down the collection basket 35 with the filter frame 36, the stability between the collection basket 35 and the filter frame 36 is enhanced, preventing the collection basket 35 from shifting or tilting during long - term use. The setting of the bottom edge 39 also facilitates the installation and disassembly of the collection basket 35, providing convenience for subsequent maintenance and cleaning work.

[0027] The width of the collection basket 35 is adapted to the width inside the card placement opening 33, and the length of the collection basket 35 is less than the inner length of the card placement opening 33. When installing the collection basket 35, it is placed from above the card placement opening 33, so that the edge of the collection basket 35 is stuck above the card rail 34 and pushed along the card rail 34 to the target position, making the collection basket 35 placed symmetrically front and back. The appropriate size matching ensures the flexibility of the collection basket 35 inside the card placement opening 33, facilitating easy removal or replacement as needed, and is conducive to daily cleaning and maintenance work.

[0028] Please refer to Figure 2 and Figure 5 As shown in, a stepped groove 311 is provided at the top of the upper well ring 31. The manhole cover 312 is movably clamped inside the stepped groove 311. A pressing plate 313 that abuts against the upper part of the filter frame 36 is fixedly connected to the bottom of the manhole cover 312. A pull rod 310 is fixedly connected inside the filter frame 36. The pressing plate 313 can be taken out by using a tool in cooperation with the through hole 314, and the manhole cover 312 and the pressing plate 313 are removed from the top of the upper well ring 31. The pull rod 310 is lifted, and the filter frame 36 is taken out from the lower well ring 32. By operating the abutting edge 39, the collection basket 35 is slid and extracted along the card rail 34, so as to disassemble the filter frame 36 and the collection basket 35 for cleaning.

[0029] Please refer to Figure 2 and Figure 5 As shown in, clamping grooves are provided on both the front and back sides of the upper well ring 31. The water guide groove 4 is movably clamped inside the clamping groove and is connected to the inside of the upper well ring 31. The design of the water guide groove 4 enables rainwater or other liquids to flow smoothly into the inside of the upper well ring 31 and then be discharged through the inside. The setting of the clamping groove not only fixes the position of the water guide groove 4 but also ensures its stability, avoiding displacement or detachment caused by external factors, making the installation and disassembly more convenient.

[0030] Working principle: Water permeates from the blind holes in the concrete base layer 1 into the inside of the drainage channel 2 through the drainage holes 6, and water on the concrete base layer 1 flows into the water guide groove 4 through the cover plate 5 and converges towards the filter well 3 and then into the upper well ring 31. The water falls into the filter frame 36 and filters impurities through its bottom, and then the water flows into the drainage channel 2 and is discharged. Since the bottom inside the filter frame 36 is arranged in an inverted "V" shape, the impurities are washed towards the lower place along with the water flow. The impurities can be discharged into the inside of the collection basket 35 through the waste discharge port 1 37 and the waste discharge port 2 38 for collection, and the small part of the water entering through the collection basket 35 is filtered again and discharged into the drainage channel 2. Thus, it is possible to avoid a large amount of impurities accumulating in the filter frame 36. By dispersing the impurities, the accumulation of impurities is effectively reduced, ensuring the water permeation and filtration effect and reducing the cleaning frequency.

[0031] During cleaning, the pressing plate 313 is hooked out of the stepped groove 311 through the through hole 314, the manhole cover 312 is driven to remove the pressing plate 313 from the top of the upper well ring 31, and the filter box 36 is lifted upward by holding the pull rod 310 to take it out of the lower well ring 32. Subsequently, the collection basket 35 can be slid downward along the card rail 34 to the inner side of the lower well ring 32 and taken out by operating the edge 39, so as to facilitate the disassembly of the filter box 36 and the collection basket 35 and facilitate the cleaning work. The above is the working process of the whole device, and the content not described in detail in this specification belongs to the prior art well known to those skilled in the art.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
