Description

Technical Field

[0001] This utility model relates to the field of rain garden technology, specifically to a self-regulating rain garden flower bed. Background Technology

[0002] Rain gardens with self-regulating flower beds are an ecologically sustainable rainwater management facility. By mimicking natural hydrological processes and through the synergistic effects of plants, soil, and microorganisms, they collect, purify, infiltrate, and store rainwater, enabling rainwater regulation and resource utilization.

[0003] According to Chinese Patent Publication No. CN221178603U, entitled "A Rainwater Garden Self-Regulating Flower Pond," the main components include: a vegetation purification layer; a water storage pond located below the vegetation purification layer, with an overflow outlet on its side wall; a water guiding layer fixed below the vegetation purification layer, configured to guide rainwater filtered and purified by the vegetation purification layer into the water storage pond; an overflow pond located on one side of the water storage pond for containing rainwater flowing out from the overflow outlet; an irrigation device one configured to supply rainwater from the overflow pond into the vegetation purification layer; and an irrigation device two configured to supply rainwater from the water storage pond into the vegetation purification layer.

[0004] The aforementioned patent enhances the city's stormwater management capabilities. During the rainy season, it can reduce flooding through water retention and storage functions; during the dry season, it can utilize its own stored water to irrigate flower beds through water storage and purification functions, thus achieving a self-circulating function.

[0005] However, common flower beds with self-regulating water storage functions often experience soil erosion during actual use. This means that the soil moves towards the water storage tank, which over time reduces the actual capacity of the tank and increases the amount of sediment, thus increasing the burden on pumps and other water-pumping structures. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a self-regulating rain garden flower bed, which facilitates the removal of silt that accumulates in the water storage tank over time and reduces damage to pumping structures such as water pumps.

[0007] This utility model provides a self-regulating rainwater garden flower bed, comprising a receiving frame, a sand layer, a gravel layer, and a fine sand layer. A filter screen is provided on the bottom side of the fine sand layer. The filter screen is fixedly connected to the upper side of the receiving frame. A water-guiding baffle is fixedly connected to the receiving frame at the bottom end of the filter screen. The water-guiding baffle has evenly distributed through holes. A drainage groove is provided on one side of the water-guiding baffle. An operating groove is provided on the side of the receiving frame near the drainage groove. An operating plate is hinged to the operating groove. An overflow hole is fixedly connected to the operating plate. A drainage frame is fixedly connected to the side of the receiving frame near the operating groove. A metal ladder is evenly fixedly connected to the side of the drainage frame away from the water-guiding baffle. A sealing plate is in contact with the upper end of the drainage frame.

[0008] Optionally, a water guiding net is fixedly connected inside the receiving frame. A groove is opened on one side of the water guiding net, and support strips are uniformly fixedly connected inside the groove. The upper end of the support strip contacts a cover net, and the cover net has the same aperture as the water guiding net.

[0009] Optionally, a drive motor is fixedly connected to the receiving frame near the operating groove, and a screw is fixedly connected to the output end of the drive motor. An abutment plate is threaded onto the screw, and the abutment plate corresponds to the water leakage groove. By setting the drive motor and the screw, the abutment plate can be moved on the bottom side of the water guide baffle, thereby changing the cross-section of the water leakage groove and thus changing the falling speed of the water.

[0010] Optionally, an auxiliary rod is movably inserted into the abutment plate, and the auxiliary rod is fixedly connected to the four sides of the inner wall of the receiving frame. By setting the auxiliary rod, the stability of the movement of the abutment plate is increased.

[0011] Optionally, a folding cover is fitted onto the outer side of both the auxiliary rod and the screw. The two ends of the folding cover are respectively fixedly connected to the abutment plate and the inner wall of the receiving frame. By setting the folding cover, protection can be provided.

[0012] As can be seen from the above technical solution, the beneficial effects of this utility model are as follows: by setting an expandable drainage frame in the receiving frame in conjunction with a metal ladder, it is convenient for personnel to move down. Then, by opening the operating panel and removing the cover net, maintenance personnel can enter the receiving frame to clean up mud and sand, thereby reducing the amount of mud and sand entering the bottom of the receiving frame under the action of water flow, which would affect the water holding capacity of the receiving frame.

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0020] Please refer to the following: Figure 1-3The diagram illustrates a self-regulating rain garden planting bed, comprising a receiving frame 1, a sand layer 2, a gravel layer 3, and a fine sand layer 4. Plants and flowers can be planted on the sand layer. A filter screen 5 (with multiple built-in support bars to provide sufficient load-bearing capacity) is installed on the bottom side of the fine sand layer 4. The pore size of the filter screen 5 is smaller than the particle size of the fine sand layer 4. The stacking of the fine sand layers 4 forms a barrier against the gravel layer 3. The filter screen 5 is fixedly connected to the upper side of the receiving frame 1. A water-guiding baffle 6 is fixedly connected to the bottom of the receiving frame 1 at the bottom of the filter screen 5. The water-guiding baffle 6, together with the abutment plate 17, facilitates the process of rainwater falling to the bottom side of the receiving frame 1. The water-guiding baffle 6 has evenly spaced through holes for rainwater to flow into the bottom of the receiving frame 1. The water-guiding baffle 6 has a drainage groove on one side, and the receiving frame 1 has an operating groove 7 on the side near the drainage groove. The operating groove 7 is hinged to the operating plate 8. Maintenance personnel can move down to the bottom of the receiving frame 1 via the metal ladder 10 for easy cleaning. An overflow hole is fixedly connected to the operating plate 8. A drainage frame 9 is fixedly connected to the side of the receiving frame 1 near the operating groove 7. The drainage frame 9 is used to collect water overflowing from the receiving frame 1. Metal ladders 10 are evenly fixedly connected to the side of the drainage frame 9 away from the water-guiding baffle 6. The upper end of the drainage frame 9 is in contact with a sealing plate 11. Under normal circumstances, the sealing plate 11 can be used to cover the drainage frame 9 to prevent dust, grass leaves, etc. from entering the drainage frame 9.

[0021] The receiving frame 1 is fixedly connected to a water guide net 12. A groove is opened on one side of the water guide net 12 and a support strip 13 is evenly fixedly connected in the groove. The upper end of the support strip 13 contacts a cover net 14. The cover net 14 has the same aperture as the water guide net 12. By setting the water guide net 12 and the cover net 14, rainwater filtration can be provided, and it is convenient for operators to open the cover net 14 and enter the bottom side of the receiving frame 1.

[0022] Among them, a drive motor is fixedly connected to the side of the receiving frame 1 near the operating groove 7, and a screw 16 is fixedly connected to the output end of the drive motor. A stop plate 17 is threadedly connected to the screw 16. The stop plate 17 corresponds to the water leakage groove. By setting the drive motor to drive the screw 16 to rotate, the stop plate 17 can be moved, thereby controlling the water inflow when the rainfall is large.

[0023] An auxiliary rod 15 is movably inserted into the abutment plate 17. The auxiliary rod 15 is fixedly connected to the four sides of the inner wall of the receiving frame 1. By setting the auxiliary rod 15, the stability of the movement of the abutment plate 17 can be increased.

[0024] The auxiliary rod 15 and the screw 16 are both fitted with folding covers 18. The two ends of the folding covers 18 are fixedly connected to the abutment plate 17 and the inner wall of the receiving frame 1, respectively. By setting the folding covers 18, the screw 16 or the auxiliary rod 15 can be reduced from being affected by water stains, thus reducing the corrosion phenomenon.

[0025] Working principle: When rainwater falls onto the receiving frame 1, the water flows sequentially from the sand layer 2, gravel layer 3, fine sand layer 4, filter screen 5, and water guiding baffle 6 into the receiving frame 1. During this process, the water undergoes multiple filtrations, and very little sand falls from the water guiding baffle 6 and the abutment plate 17 onto the water guiding net 12. At the same time, during regular maintenance, operators can open the sealing plate 11 and then enter the bottom side of the drainage frame 9 via the metal ladder 10. Then, they can open the operating plate 8 and the cover net 14 to enter the bottom side of the receiving frame 1, thereby cleaning up the water and soil entering the bottom side of the receiving frame 1.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
