Description

Technical Field

[0001] This invention belongs to the field of urban green space technology, and in particular relates to a green space infiltration blind pipe system for urban rainwater harvesting. Background Technology

[0002] Drainage is a crucial consideration in green spaces. Drainage methods include open ditches and blind drains. Open ditches offer diverse design options, while blind drains are discreet and unobtrusive. Burying blind pipes within green spaces for drainage is a common practice. Horticultural drainage blind pipes differ slightly in material from ordinary engineering blind pipes. They utilize lightweight, highly permeable materials such as natural volcanic rock, suitable for plant growth, as filling and filtering materials. This not only solves the drainage problem of the green base but also addresses the issue of lawn color variation often encountered with ordinary engineering blind pipes.

[0003] Compared with existing technologies, current methods of collecting rainwater in green spaces all involve directly burying blind pipes in the soil beneath the green space. Rainwater is collected through direct infiltration. However, after long-term use, the underground blind pipes may shift and deform, which affects the drainage effect. Summary of the Invention

[0004] Based on the technical problems existing in the background technology, the present invention proposes a green space infiltration blind pipe system for urban rainwater harvesting.

[0005] The present invention proposes a green space infiltration blind pipe system for urban rainwater harvesting, including a support frame and multiple first blind pipes. The multiple first blind pipes are arranged below the support frame and are arranged in a row. Multiple second blind pipes are connected between the multiple first blind pipes. A drainage trough is provided on one side of the support frame, and one end of the multiple first blind pipes is connected to the drainage trough.

[0006] Multiple connecting blocks are fixedly connected to the bracket. A water pipe is inserted and snapped into each connecting block. The lower end of the water pipe is connected to a third blind pipe. The end of the third blind pipe away from the water pipe is connected to the first blind pipe. An inclined plate is provided below the third blind pipe. One end of the inclined plate is fixedly connected to the connecting block through a snap-fit ​​mechanism.

[0007] The bottom of the bracket is provided with multiple fixing mechanisms. The first blind tube is fixedly connected to the bracket through the fixing mechanisms. The fixing mechanisms include a first connecting plate and a second connecting plate that are symmetrically arranged and rotatably connected.

[0008] Preferably, the outer surface of the water pipe is provided with a retaining ring, which is engaged with the surface of the connecting block. A floor drain is engaged at the upper end of the water pipe, and the lower end of the water pipe passes through the connecting block and is inserted into the third blind pipe.

[0009] Preferably, the snap-fit ​​mechanism includes a snap-fit ​​shaft, and a snap-fit ​​groove is provided at one end of the inclined plate near the connecting block. The snap-fit ​​groove snaps into the connecting block from below. Grooves are provided on both outer surfaces of the snap-fit ​​groove. Both ends of the snap-fit ​​shaft are sleeved with the ends of the snap-fit ​​groove, and two elastic pieces are snapped into the two grooves respectively.

[0010] Preferably, the fixing mechanism further includes a U-shaped connecting shaft, the lower ends of the two first connecting plates are rotatably connected together, and a pin is rotatably connected at the rotatable connection position. The pin is used to insert into the soil. The upper end of the first connecting plate is rotatably connected to the lower end of the second connecting plate. Movable pieces are rotatably connected to the upper ends of the two second connecting plates. Fixed shafts corresponding to the fixing mechanism are symmetrically fixed at the bottom of the bracket. The upper end of the U-shaped connecting shaft is respectively engaged with the fixed shaft. The U-shaped connecting shaft passes through the two movable pieces.

[0011] Preferably, both movable pieces are provided with through holes, and the U-shaped connecting shaft passes through the two through holes. The upper end of the U-shaped connecting shaft is T-shaped, and the two sides are hook-shaped. There are four corresponding fixed shafts, which are arranged symmetrically in pairs. The two fixed shafts have slots on the side facing each other, and the U-shaped connecting shaft is engaged with the slots on the fixed shafts through the T-shape.

[0012] Preferably, bolts are fixedly connected to the facing sides of the two movable plates, the two bolts are staggered, both bolts pass through the opposite movable plates, and both bolts are threaded with nuts, one of the nuts is located on the inner side of the two movable plates, and the other nut is located on the outer side of the two movable plates.

[0013] Preferably, the drainage trough has an opening, and a grid plate is installed on the opening, the grid plate being flush with the ground.

[0014] Preferably, the inclined plate has multiple holes on its surface and has a mesh structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. Rainwater that does not infiltrate the ground can flow through the water pipe, along the third blind pipe, into the first blind pipe.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] Reference Figure 1-5 A green space infiltration blind pipe system for urban rainwater harvesting includes a support 2 and multiple first blind pipes 3. The multiple first blind pipes 3 are arranged below the support 2 and are arranged in a row. Multiple second blind pipes 4 are connected between the multiple first blind pipes 3. A drainage trough 1 is provided on one side of the support 2, and one end of the multiple first blind pipes 3 is connected to the drainage trough 1.

[0026] Multiple connecting blocks 7 are fixedly connected to the bracket 2. A water pipe 6 is inserted and snapped into each connecting block 7. The lower end of the water pipe 6 is connected to a third blind pipe 5. The end of the third blind pipe 5 away from the water pipe 6 is connected to the first blind pipe 3. An inclined plate 8 is provided below the third blind pipe 5. One end of the inclined plate 8 is fixedly connected to the connecting block 7 through a snap-fit ​​mechanism.

[0027] The bottom of the bracket 2 is provided with multiple fixing mechanisms 9. The first blind tube 3 is fixedly connected to the bracket 2 through the fixing mechanism 9. The fixing mechanism 9 includes a first connecting plate 23 and a second connecting plate 22 that are symmetrically arranged and rotatably connected.

[0028] A retaining ring 11 is provided on the outer surface of the water pipe 6, which engages with the surface of the connecting block 7. A floor drain 10 is attached to the upper end of the water pipe 6, and the lower end of the water pipe 6 passes through the connecting block 7 and is inserted into the third blind pipe 5. The water pipe 6 is inserted into the soil, and rainwater that has not infiltrated the surface can be directly transported downward through the water pipe 6. A floor drain 10 is provided at the upper end of the water pipe 6 to block impurities and prevent them from flowing in and causing internal blockage. The water pipe 6 is secured to the connecting block 7 by the retaining ring 11.

[0029] The locking mechanism includes a locking shaft 12. A locking groove 13 is provided at one end of the inclined plate 8 near the connecting block 7. The locking groove 13 engages with the connecting block 7 from below. Grooves 14 are provided on both outer surfaces of the locking groove 13. Both ends of the locking shaft 12 are sleeved with the ends of the locking groove 13, and two elastic pieces 15 are respectively locked within the two grooves 14. When installing the third blind pipe 5, because it is inclined, digging and placement are relatively troublesome. Therefore, an inclined plate 8 is installed below it. The inclined plate 8 shapes the installation location, clearing a suitable space for placement before the third blind pipe 5 is placed. The inclined plate 8 is detachable from the connecting block 7. The upper end of the inclined plate 8 is locked with the connecting block 7 via the locking groove 13, and then the elastic pieces 15 at both ends of the locking shaft 12 are locked with the grooves 14, thus fixing the relative position of the locking groove 13. The elastic pieces 15 are elastic and can be sleeved with both ends of the locking groove 13 from top to bottom.

[0030] The fixing mechanism 9 also includes a U-shaped connecting shaft 18. The lower ends of the two first connecting plates 23 are rotatably connected together, and a pin 24 is rotatably connected at the rotatable connection point. The pin 24 is used to insert into the soil. The upper end of the first connecting plate 23 is rotatably connected to the lower end of the second connecting plate 22. Movable pieces 19 are rotatably connected to the upper ends of the two second connecting plates 22. Fixed shafts 16 corresponding to the fixing mechanism 9 are symmetrically fixed at the bottom of the bracket 2. The upper ends of the U-shaped connecting shaft 18 are respectively engaged with the fixed shafts 16. The U-shaped connecting shaft 18 passes through the two movable pieces 19. After digging a pit in the ground to bury the first blind pipe 3, the pin 24 is inserted into the pit, and then the first blind pipe 3 is wrapped within the space formed by the combination of the second connecting plate 22 and the first connecting plate 23. The fixing mechanism 9 plays a shaping role. The upper ends of the two second connecting plates 22 are connected by the U-shaped connecting shaft 18. The U-shaped connecting shaft 18 is engaged with the fixed shaft 16 to fix it, thereby stabilizing the position of the first blind pipe 3 relative to the bracket 2.

[0031] Both movable plates 19 have through holes 25. A U-shaped connecting shaft 18 passes through both through holes 25. The upper end of the U-shaped connecting shaft 18 is T-shaped, and the two sides are hook-shaped. Four corresponding fixed shafts 16 are provided, arranged symmetrically in pairs. A slot 17 is provided on the side of the two fixed shafts 16 facing each other. The U-shaped connecting shaft 18 is engaged with the slot 17 on the fixed shaft 16 through the T-shape. The U-shaped connecting shaft 18 passes through the two movable plates 19, which can slide relative to each other within a range to adjust their position to fit the size of the first blind tube 3. The upper end of the U-shaped connecting shaft 18 is engaged and fixed with the two fixed shafts 16 through the T-shaped structure. The detachable engagement structure facilitates the installation and disassembly of the entire device.

[0032] Two movable plates 19 are fixedly connected to each other on their facing sides with bolts 20. The two bolts 20 are staggered and pass through the opposite movable plates 19. Each bolt 20 has a nut 21 threaded onto its thread, with one nut 21 located on the inner side of the two movable plates 19 and the other on the outer side. The distance between the two movable plates 19 is adjusted by using the two bolts 20. The bolts 20 pass through the opposite movable plates 19, and nuts 21 are located on both the inner and outer sides of the two movable plates 19. This staggered arrangement fixes the relative distance between the two movable plates 19.

[0033] The drainage channel 1 has an opening, on which a mesh plate is installed, flush with the ground. The drainage channel 1 is designed for rainwater collection; the mesh plate at the opening at the top allows rainwater to flow smoothly in and be collected and discharged. The inclined plate 8 has multiple holes on its surface and is a mesh structure. These holes prevent the inclined plate 8 from obstructing rainwater, facilitating infiltration. The mesh structure also makes it relatively lightweight, facilitating transportation and installation.

[0034] When installing this system, firstly, dig corresponding trenches in the green space. These trenches are used to bury and install the first blind pipe 3 and the second blind pipe 4. Before installing the first blind pipe 3 and the second blind pipe 4, first install the fixing mechanisms 9. The fixing mechanisms 9 wrap and fix the first blind pipe 3, securing its position and maintaining its shape. The second blind pipe 4 is inserted and connected to the side of two adjacent first blind pipes 3, thus connecting the first blind pipes 3 to each other. At the same time, a third blind pipe 5 is also inserted next to the first blind pipe 3. First, a lateral inclined plate 8 is inserted, creating a suitable passage to facilitate the fixing of the third blind pipe 5. The inclined plate 8 is embedded in the soil. After the position is fixed, the third blind pipe 5 is inserted into the first blind pipe 3 along the inclined plate 8. Finally, the fixing mechanism 9 is connected to the bracket 2, and the inclined plate 8 is connected to the bracket 2 through the snap-fit ​​mechanism. The position of the inclined plate 8 is set corresponding to the connecting block 7. The water pipe 6 is inserted into the connecting block 7 and connected to the third blind pipe 5. Then, the rainwater that has not infiltrated the ground can flow into the first blind pipe 3 through the water pipe 6 along the third blind pipe 5. The water pipe 6 extends into the ground and is flush with the ground, so that the rainwater can flow smoothly downward. Finally, the bracket 2 is buried in the upper soil of the green space. The drainage ditch 1 is set at the edge of the green space, and all rainwater is discharged through the drainage ditch 1.

[0035] The inclined plate 8 is connected to the connecting block 7 through a snap-fit ​​mechanism. The lower end of the inclined plate 8 is inserted into the soil to form an inclined channel. Then, the third blind pipe 5 is installed along the inclined plate 8. The upper end of the inclined plate 8 is snapped to the bottom of the connecting block 7 through the snap-fit ​​groove 13. Then, the snap-fit ​​shaft 12 is snapped in from the top. The elastic pieces 15 at both ends of the snap-fit ​​shaft 12 are snapped into the grooves 14 on both sides, thereby connecting the inclined plate 8 and the connecting block 7.

[0036] The first blind tube 3 is fixed by the fixing mechanism 9. The two first connecting plates 23 are rotatably connected, and the second connecting plate 22 is also rotatably connected to the first connecting plate 23. The movable connection can adapt to the first blind tube 3 of different diameters. The distance between the two movable pieces 19 can be adjusted according to the actual size. After the relative position of the two movable pieces 19 is determined, they are fixed by bolts 20, and then the bolts 20 are fixed by nuts 21. The two movable pieces 19 pass through a U-shaped connecting shaft 18. The upper end of the U-shaped connecting shaft 18 is respectively engaged and fixed with the fixed shafts 16 on both sides. The adjustable method can effectively adapt to the size of the first blind tube 3 in different environments.

[0037] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
