Traditional reinforced concrete water storage tanks suffer from problems such as long construction periods, large land areas, and inflexible layouts, making them difficult to adapt to the diverse needs of modern architecture, especially in landscape engineering, for space utilization and aesthetics.

[0003] In recent years, the release of the industry standard CJJ / T311-2020, "Technical Standard for Modular Rainwater Storage Facilities," has promoted the standardized application of modular plastic water storage technology. However, existing technologies still have significant limitations in practical engineering applications. Specifically: (1) Single function: Conventional water storage modules are standardized blocks, which makes it difficult to integrate them with ground landscape facilities (such as landscape low walls) in an aesthetically pleasing and concealed manner; (2) Insufficient boundary adaptability: Standard modules are difficult to adapt flexibly to complex boundary structures such as corners and polygons commonly found in landscape engineering; (3) Inconvenient daily maintenance: The filter device of the integrated rainwater harvesting system is usually buried deep or closed, and it is extremely difficult to clean after intercepting dirt, which can easily cause blockage and thus affect the long-term water quality and stable operation of the system.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) This invention achieves high flexibility and adaptability through modular design.

Together with the straight water storage tank and the corner water storage tank in the bottom water storage module, they form a complete internal and external water storage space. This design allows the top plug-in module and the bottom water storage module to fit closely to the outline of the prefabricated foundation wall components. The integrated installation of the rainwater collection system can be completed quickly without major changes to the civil engineering structure. The portal cavity structure of the starting module, plug-in module, corner module and end module is not only lightweight and sturdy, but also forms a unified top connection interface, ensuring the overall visual continuity and structural stability. The interfaces between each module are clear and the connection sequence is clear, which greatly reduces the construction complexity, facilitates large-scale production and on-site assembly, and is suitable for diverse landscape layout requirements. (2) The present invention improves the cleanliness and maintenance efficiency of rainwater collection by setting a preliminary filtration mechanism in the upper part of the starting module, plug-in module, corner module and end module and a dual-mode filtration component with switchable mode. The preliminary filtration mechanism set in the upper part of the starting module, plug-in module, corner module and end module first intercepts larger debris. Then the rainwater enters the third filter cartridge through the bottom outlet. In the filtration state of the dual-mode filtration component, the rotating drum rotates to align the third filter block with the inlet of the third filter cartridge. The switching sealing block closes the waste discharge pipe, so that the rainwater enters the bottom water storage module after fine filtration. When cleaning is required, the rotating drum rotates to switch to the backwashing mode. The third filter block aligns with the waste discharge pipe. The switching sealing block closes the outlet of the third filter cartridge. The water flow can be used to flush away the intercepted dirt and discharge it through the waste discharge pipe. This design avoids the tedious disassembly and cleaning of filter media, extends the life of the filter unit, ensures the water quality of the stored water and greatly reduces the long-term operation and maintenance costs.

[0031] Secondary filtration and water storage filtration mode: Under the tension of spring 626, the rotating drum 609 is in the filtration position, the third filter block 616 faces the outlet of the filter inlet pipe 605, and the conversion sealing block 617 faces and closes the waste discharge pipe 608. The rainwater after preliminary filtration flows into the third filter drum 604 from the drain pipe 212, and after fine filtration by the third filter block 616, it enters the bottom water storage module 4 for storage. The preliminary filtration and secondary filtration of rainwater are both positive pressure gravity filtration processes. The design resistance of the filter media must be less than the gravitational potential energy of the usable water to ensure flow rate. At the same time, the mesh size of the first filter plate 301, the second filter plate 302, and the third filter block 616 increases sequentially to form a staged filtration of rainwater.

[0032] Example 2: Based on Embodiment 1, this invention adds a waist panel component 5 to enhance the decorative effect and a snap fastener component 7 to improve operability. Figure 1 , Figure 13 , Figure 14 , Figure 19 and Figure 20 As shown.

[0033] like Figure 13 and Figure 14 As shown, upper slots 213 are provided on both outer edges of the bottom ends of the starting module 201, the plug-in module 202, the corner module 203, and the end module 204; lower slots 404 are provided on the outer edges of the top ends of the in-line water storage tank 401 and the corner water storage tank 407; the integrated plastic rainwater storage module structure of the landscape low wall also includes a waist plate component 5, including a decorative waist plate 501 and insertion holes 502 arranged in the main body of the decorative waist plate 501. The decorative waist plate 501 is inserted between the upper slot 213 and the lower slot 404 on the same side below, and is used to form a decorative space between the upper and lower slots on the same side.

[0034] like Figure 19 and Figure 20 As shown, the lower end of the main body of the positioning slide 216 is evenly provided with locking holes 217, and each set of locking holes 217 has a locking groove 218 at the outer edge; the lower part of the prefabricated groove 104 has a prefabricated hole 105; the landscape low wall integrated plastic rainwater storage module structure also includes a snap-fit ​​component 7, including a fixed plate 701, a sealing cover 704 and a sliding inclined surface 705. A claw arm 702 is fixedly arranged at one end of the fixed plate 701, and a locking boss 703 is fixed on the outer side of the head end of each set of claw arms 702. The sliding inclined surface 705 is opened on the outer edge of the locking boss 703, and a normally closed sealing cover 704 is fixed in the middle of the main body of the fixed plate 701.

[0035] After each module is assembled, the upper slot 213 and lower slot 404 on the same side are aligned. After the decorative waist plate 501 is inserted into place, the insertion hole 502, the locking hole 217, and the pre-made hole 105 are aligned. The snap fastener 7 passes through the insertion hole 502, and the head end of the claw arm 702 is inserted into the locking hole 217. The sliding inclined surface 705 and the locking inclined groove 218 are slidably and tangentially engaged to guide the locking boss 703 to engage on the other side of the locking hole 217, and the head end of the claw arm 702 extends into the pre-made hole 105. In this way, through the insertion and engagement of the snap fastener 7, the top insertion module 2, the bottom water storage module 4, the waist plate component 5, and the third filter cartridge 604 are formed into a detachable integral module.

[0036] Dual-mode filter assembly backwashing mode: When it is necessary to clean the dirt trapped in the dual-mode filter assembly 6, use a special tool to pass through the normally closed sealing cover 704, press against the hexagonal plate 614 and extend into the hexagonal groove 613 to drive the rotating drum 609 to rotate. At this time, the rotating drum 609 switches to the backwashing state, the third filter block 616 is facing the inlet of the waste discharge pipe 608, and the switching sealing block 617 is facing and closing the outlet of the third filter cylinder 604. At this time, the gravity potential energy of the water flow above is used to backwash the third filter block 616, and the flushed dirt is discharged through the waste discharge pipe 608, completing the cleaning and maintenance.
