Description

Technical Field

[0001] This utility model belongs to the field of municipal drainage structure technology, specifically relating to a landscape-integrated ecological rainwater inlet device. Background Technology

[0002] In urban drainage systems, traditional storm drains typically use cast iron grates. This type of drain has a very limited function, primarily collecting rainwater from the road surface, making it inadequate for handling large volumes of runoff during the rainy season. Furthermore, its openings are easily clogged by fallen leaves and debris, leading to poor drainage and exacerbating the risk of urban flooding. Simultaneously, traditional storm drains lack primary filtration capabilities, allowing pollutants such as oil, silt, and garbage carried by the rainwater to be discharged directly into natural water bodies without treatment, causing serious non-point source pollution and damaging the ecological environment.

[0003] From a landscape perspective, cast iron rainwater inlets, as gray infrastructure, clash with the surrounding natural landscape and affect the overall visual aesthetics of the city.

[0004] Although planting greenery has been attempted above some rainwater inlets, the lack of rainwater recycling channels means the plants still rely on artificial irrigation during the dry season, hindering the effective collection and utilization of rainwater for plant nourishment and resulting in water waste. This makes it difficult to achieve a closed-loop ecological integrated structure for rainwater collection, purification, and reuse. Therefore, this paper proposes an integrated landscape ecological rainwater inlet device to address the aforementioned technical problems. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a landscape-integrated ecological rainwater inlet device to solve the technical problems of existing rainwater inlet structures lacking rainwater reuse channels, requiring artificial irrigation of plants during the dry season leading to water waste, and making it difficult to achieve a closed-loop ecological integrated structure for rainwater collection, purification, and reuse.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An integrated ecological rainwater inlet device for landscaping includes a base box with a drain outlet. A frame is inserted into the opening of the base box. A flat floor with a water inlet is fixedly installed on the upper surface of the frame. A filter grate is embedded in the water inlet of the flat floor. A multi-stage filtration device is detachably installed inside the frame. Two water collection chambers are symmetrically arranged inside the frame. The multi-stage filtration device is located above the water collection chambers. A planter is installed above the flat floor. Four through holes are opened through the lower surface of the planter. A hollow square tube is fixedly installed at each of the four through holes. The lower end of each hollow square tube is inserted into the frame through the flat floor. An absorbent cotton rope is inserted between the two hollow square tubes on the left and right sides. The middle section of the absorbent cotton rope is located inside the planter, and the two ends of the absorbent cotton rope are located in the corresponding water collection chambers.

[0008] In the above technical solution, two L-shaped brackets are symmetrically fixedly installed in the frame. The multi-stage filtration device includes a carrier box with a hollow bottom. The bottom of the inner cavity of the carrier box is lined with a zeolite layer, and two slots are opened on the right surface of the carrier box. The slots extend to the inner side wall of the carrier box. A first filter screen is inserted into the upper slot, and a second filter screen is inserted into the lower slot. The filter diameter of the second filter screen is smaller than that of the first filter screen.

[0009] In the above technical solution, a U-shaped support block is fixedly installed on the outer surface of the hollow square tube, and the lower surface of the support block is in contact with the upper surface of the flat floor.

[0010] In the above technical solution, a trapezoidal guide plate is fixedly installed inside the frame. The two ends of the trapezoidal guide plate are respectively located above the two water collection chambers, and the trapezoidal guide plate is located below the carrier box.

[0011] In the above technical solution, a gravel layer is laid inside the bottom box, and a permeation pipe is fixedly installed through the rear surface of the bottom box.

[0012] The integrated ecological rainwater inlet device for landscaping of this utility model has the following advantages compared with the prior art:

[0013] This utility model, through components such as a base box, frame, and carrier box, effectively ensures smooth drainage and purifies water quality by allowing rainwater to pass through a multi-stage filtration process involving a filter grate, filter screen, and zeolite before being stored in a collection chamber, discharged into a drainage ditch, or infiltrated into the soil. Regarding resource utilization, absorbent cotton ropes can be used to supply rainwater collected in the collection chamber to plants in the planters, avoiding water waste. Aesthetically, planting greenery in the planters enhances the overall appearance of the device. The entire system achieves a closed-loop ecological integrated structure for rainwater collection, purification, and reuse, combining practicality and ecological benefits.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In this embodiment, front, back, left, right, top, and bottom are... Figure 1 Describe the reference plane. See [link / reference] Figures 1-4 This utility model provides a technical solution:

[0021] An integrated ecological rainwater inlet device for landscaping includes a base box 1 with a drain outlet 11 extending through its front surface. A notch is formed inside the opening of the base box 1, into which a frame 2 is inserted. A flat floor 21 with a water inlet is welded and fixed to the upper surface of the frame 2. A filter grate 22 is embedded in the water inlet of the flat floor 21, providing initial filtration of rainwater entering the frame 2. A detachable multi-stage filtration device 3 and two water collection chambers are installed inside the frame 2. The multi-stage filtration device 3 provides secondary filtration of rainwater, and the two water collection chambers are located below the multi-stage filtration device 3. The water collection chamber is used to collect filtered rainwater. A planter 4 is installed above the flat floor 21. Four openings are provided on the lower surface of the planter 4. Hollow square tubes 41 are welded and fixed to each of the four openings. The lower ends of the hollow square tubes 41 are inserted into the frame 2 through the flat floor 21. A water-absorbing cotton rope 42 is inserted between the two hollow square tubes 41 on the left and right. The two ends of the water-absorbing cotton rope 42 are located in the corresponding water collection chambers. When green plants are planted in the planter 4, the water-absorbing cotton rope 42 can be used to absorb and conduct the rainwater collected in the water collection chamber to the soil in the planter 4 to nourish the green plants.

[0022] Combination Figure 2 and Figure 4 As shown, two V-shaped sealing plates 24 are welded and fixed in the inner cavity of the frame 2. The water collection cavity is formed after the V-shaped sealing plates 24 are assembled with the frame 2.

[0023] like Figure 2 As shown, the outer surface of the hollow square tube 41 is welded and fixed with U-shaped support blocks 411. The lower surface of the support block 411 is in contact with the upper surface of the flat floor 21. By setting the support block 411, a certain amount of rainwater can be left between the green plant pot 4 and the filter grate 22, so that rainwater can enter the frame 2 normally.

[0024] Combination Figure 2 and Figure 3 As shown, two L-shaped brackets 23 are symmetrically fixedly installed inside the frame 2;

[0025] The multi-stage filtration device 3 includes a container 31 with a hollow bottom. The container 31 is inserted into the water inlet of the flat floor 21 and installed between two L-shaped brackets 23. Two slots 311 are opened on the right surface of the container 31. Both slots 311 extend to the inner side wall of the container 31. A first filter screen 32 and a second filter screen 33 are respectively inserted into the two slots 311. The filter diameter of the second filter screen 33 is smaller than that of the first filter screen 32, and the first filter screen 32 is located above the second filter screen 33. A filler area is reserved between the second filter screen 33 and the bottom of the inner cavity of the container 31.

[0026] In actual use, zeolite can be filled in the filling area to form a zeolite layer. When rainwater enters the frame 2 from the inlet of the flat floor 21, it passes through the first filter screen 32, the second filter screen 33 and the zeolite layer in sequence for multi-stage filtration. After filtration, the rainwater flows down to the water collection chambers on both sides below for collection. When the water collection chambers are full of rainwater, the rainwater overflows and flows into the bottom box 1 below.

[0027] like Figure 2 or Figure 4 As shown, in order to facilitate the immediate entry of downstream rainwater into the water collection chamber, a trapezoidal guide plate 25 is fixedly installed inside the frame 2. The two ends of the trapezoidal guide plate 25 are respectively located above the two water collection chambers, and the trapezoidal guide plate 25 is located below the carrier box 31. When rainwater flows down from the carrier box 31, it can be guided to the two water collection chambers for collection with the help of the trapezoidal guide plate 25.

[0028] Finally, combining Figure 2 and Figure 4 As shown, multiple infiltration pipes 12 are fixedly installed through the rear surface of the bottom box 1. The infiltration pipes 12 are installed at a position lower than the drain outlet 11. In actual use, gravel filler is filled into the bottom box 1 to form a gravel layer. The filling height of the gravel layer is lower than the drain outlet 11 and higher than the infiltration pipes 12. Then, the bottom box 1 is pre-buried in the drainage ditch, and the infiltration pipes 12 are pre-buried in the soil. In this way, the rainwater in the bottom box 1 can be discharged into the culvert while being further filtered by the gravel layer and discharged into the soil through the infiltration pipes 12 to moisten the soil.

[0029] Working principle: In use, first, the bottom box 1 is pre-buried in the drainage ditch, and the infiltration pipe 12 is pre-buried in the soil. Then, a gravel layer is filled into the bottom box 1. Next, the frame 2 is inserted and installed inside the opening of the bottom box 1 and pre-buried. After pre-buried, as... Figure 1 As shown, the upper surface of the flat floor 21 is kept level with the ground. Then, zeolite is filled into the bottom of the inner cavity of the carrier box 31, and the first filter screen 32 and the second filter screen 33 are inserted into the slot 311. Then, the carrier box 31 is inserted and installed between the two L-shaped brackets 23 from the water inlet of the flat floor 21. After that, the water filter grate 22 is installed at the inlet of the flat floor 21. Finally, the green plant pot 4 with water-absorbing cotton rope 42 is inserted into the frame 2 by passing the hollow square tube 41 through the flat floor 21, so that the end of the water-absorbing cotton rope 42 falls into the water collection cavity. Planting green plants in the green plant pot 4 can increase the overall aesthetics of the device.

[0030] When the rainy season arrives, rainwater first passes through the filter grate 22 for initial filtration before entering the frame 2. Then, after passing through the first filter screen 32, the second filter screen 33, and zeolite for multi-stage filtration, it enters the water collection chambers on both sides for storage. Rainwater overflowing from the water collection chambers enters the bottom box 1 and is discharged into the drainage ditch through the drain outlet 11. It is then discharged into a large water storage tank for further collection and storage. Some rainwater is filtered through the gravel layer and seeps into the soil through the infiltration pipe 12 for use. The overall design allows the rainwater collected in the water collection chamber to be used by the water-absorbing cotton rope 42 without affecting drainage, thus avoiding water waste and realizing a closed-loop ecological integrated structure for rainwater collection, purification, and reuse.
