Description

Technical Field

[0001] This invention belongs to the field of green space technology, and in particular relates to a low-impact ecological green space infiltration system with a permeable layer. Background Technology

[0002] By integrating green space with site planning and design, watershed control areas are determined based on the city's topography and flood control standards, and are also considered in conjunction with the corresponding soil geology. Rainwater can flow into sunken green spaces, ensuring the safety of pedestrians and vehicles; this is a commonly used green space design method in urban construction.

[0003] The publicly available document (publication number CN207435843U) discloses a low-impact development rainwater system based on sunken green space, which has a simple structure and good performance. Through the setting of water storage and drainage structures, rainwater is effectively stored and utilized. Through the setting of filter tanks, debris in the rainwater flowing into the water storage and drainage structures is filtered, which effectively protects the vegetation on the sunken green space and prevents rainwater from flowing into the drainage structure and clogging the municipal rainwater inspection well.

[0004] As is known from existing technology, green space drainage is usually achieved by directly setting up drainage pipes. However, since this drainage system is directly exposed on the ground, impurities carried by rainwater can easily cause blockages in the pipes. If a single blind pipe is used for drainage, the drainage efficiency depends on the soil's infiltration efficiency. Summary of the Invention

[0005] Given the existing technical issues, drainage systems are directly exposed to the ground, and impurities carried by rainwater can easily cause blockages in the pipes. Furthermore, if a single blind pipe is used for drainage, the drainage efficiency depends on the soil's infiltration efficiency. Therefore, this invention proposes a low-impact ecological green space infiltration system with a permeable layer.

[0006] The present invention proposes a low-impact ecological green space infiltration system with a permeable layer, including a support frame with multiple legs fixedly connected to the support frame. Both the support frame and the legs are buried in the soil. A drainage pipe is installed inside the support frame. An inner sliding pipe is slidably connected to the upper end of the drainage pipe. A driving mechanism is installed at the upper end of the drainage pipe and the driving mechanism is connected to the inner sliding pipe.

[0007] The bracket is also symmetrically provided with blind pipes on its outer side, and each blind pipe is connected to a connecting pipe. The end of the connecting pipe away from the blind pipe is connected to the drain pipe.

[0008] The bracket is fitted with a U-shaped locking block, and the U-shaped locking block is equipped with an adjustment mechanism. Multiple arc-shaped pieces are symmetrically slidably arranged on the surface of each blind tube relative to the connecting tube. Two adjacent arc-shaped pieces are connected together by a connecting line. The adjustment mechanism is used to adjust the distance between each arc-shaped piece.

[0009] Preferably, the arc-shaped piece is slidably disposed on the upper surface of the blind tube, and the blind tube is provided with limiting shafts corresponding to the arc-shaped piece on both sides. The end of the arc-shaped piece passes through the limiting shaft, and the two ends of the limiting shaft are fixedly connected to the surface of the blind tube.

[0010] Preferably, the bracket has an opening corresponding to the U-shaped locking block, the U-shaped locking block passes through the opening from the inside of the bracket, and the opening of the U-shaped locking block faces the outer side of the bracket.

[0011] Preferably, the adjusting mechanism includes a collar sleeved on the connecting pipe, the collar also being sleeved on the lower end of the U-shaped block, fixed shafts being symmetrically fixedly connected to both sides of the lower end of the U-shaped block, a linkage shaft being rotatably connected to one side of each of the two fixed shafts, a connecting shaft being fixedly connected to one side of one of the arc-shaped pieces, and the end of the linkage shaft away from the fixed shaft being rotatably connected to the connecting shaft.

[0012] Preferably, the driving mechanism includes two symmetrically arranged threaded shafts. The top plate is fixedly connected to the drain pipe via a support shaft. The support shaft is fixedly installed on the outer surface of the drain pipe. The two threaded shafts are symmetrically rotated and installed below the top plate and on the outside of the drain pipe. A connecting plate is symmetrically fixedly connected to the upper end of the inner sliding pipe. An arc-shaped block is provided at the lower end of each of the two connecting plates. The two threaded shafts are threaded through the two arc-shaped blocks respectively. A linkage mechanism is provided on the top plate.

[0013] Preferably, the linkage mechanism includes a chain, a dual-head motor is fixedly installed on the lower surface of the top plate, one drive end of the dual-head motor is fixedly connected to one of the threaded shafts, the other drive end of the dual-head motor is fixedly connected to a rotating shaft, and sprockets are fixedly connected to the upper end of the other threaded shaft and the rotating shaft, the two sprockets are connected together by the chain, and the sprockets mesh with the chain.

[0014] Preferably, a spring is connected between the upper end of the U-shaped locking block and the collar.

[0015] Preferably, an inclined filter screen is installed inside the drain pipe, the filter screen is positioned above the connecting pipe, and a support ring is provided on the inner wall of the blind pipe.

[0016] Preferably, the plane with the wider linkage shaft is vertically arranged, and the plane with the wider connecting shaft is horizontally arranged.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. After the inner sliding pipe descends, it will be significantly lower than the ground water level. The surrounding rainwater will flow into the drain pipe, and the garbage and impurities in the rainwater will also flow into the drain pipe. A filter screen is installed inside the drain pipe, which will block the garbage and impurities. Some of the rainwater will still flow downwards. The rainwater will be discharged into the sewer through the connecting pipe and blind pipe, and there will be no problem of blockage due to impurities.

[0019] 2. When the amount of rainwater is large, the weight of the connecting pipe will increase. The connecting pipe will deform by pulling the U-shaped clamp through the collar. The fixed shaft drives the linkage shaft to move. The linkage shaft pushes the arc-shaped pieces further away, so that each arc-shaped piece is dispersed, which plays a role in blocking and avoiding deformation under pressure, thereby maintaining the stability of the structure.

[0026] 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.

[0027] Reference Figures 1-5A low-impact ecological green space infiltration system with a permeable layer includes a support frame 1, with multiple legs 2 fixedly connected to the support frame 1. Both the support frame 1 and the legs 2 are buried in the soil. A drainage pipe 3 is installed inside the support frame 1. An inner sliding pipe 4 is slidably connected to the upper end of the drainage pipe 3. A drive mechanism is installed at the upper end of the drainage pipe 3 and is connected to the inner sliding pipe 4. Blind pipes 6 are also symmetrically arranged on the outside of the support frame 1. Each blind pipe 6 is connected to a connecting pipe 7. The end of the connecting pipe 7 away from the blind pipe 6 is connected to the drainage pipe 3.

[0028] A U-shaped locking block 12 is attached to the bracket 1. An adjustment mechanism is provided on the U-shaped locking block 12. Multiple arc-shaped pieces 9 are symmetrically slidably arranged on the surface of each blind tube 6 relative to the connecting tube 7. Two adjacent arc-shaped pieces 9 are connected together by a connecting line 22. The adjustment mechanism is used to adjust the distance between each arc-shaped piece 9.

[0029] The arc-shaped pieces 9 are slidably disposed on the upper surface of the blind tube 6. Limiting shafts 21 corresponding to the arc-shaped pieces 9 are also provided on both sides of the blind tube 6. The ends of the arc-shaped pieces 9 pass through the limiting shafts 21, and both ends of the limiting shafts 21 are fixedly connected to the surface of the blind tube 6. The limiting shafts 21 pass through the ends of the arc-shaped pieces 9, and are relatively fixed to the blind tube 6. Under the action of the adjusting mechanism, each arc-shaped piece 9 will slide on the surface of the blind tube 6, thus providing a barrier to the upper surface of the blind tube 6. When the soil settles due to rainwater, the arc-shaped pieces 9 can be used to provide this barrier, ensuring the shape of the blind tube 6 remains intact.

[0030] The bracket 1 has an opening 24 corresponding to the U-shaped locking block 12. The U-shaped locking block 12 passes through the opening 24 from the inside of the bracket 1, with the opening of the U-shaped locking block 12 facing the outside of the bracket 1. The U-shaped locking block 12 is inserted from the inside of the bracket 1 and into the opening 24, thus realizing the installation of the U-shaped locking block 12 on the bracket 1.

[0031] The adjusting mechanism includes a collar 23 fitted onto the connecting pipe 7, which is also fitted onto the lower end of a U-shaped locking block 12. Fixed shafts 8 are symmetrically fixed to both sides of the lower end of the U-shaped locking block 12. A linkage shaft 10 is rotatably connected to one side of each of the two fixed shafts 8. A connecting shaft 11 is fixedly connected to one side of one of the arc-shaped pieces 9. The end of the linkage shaft 10 furthest from the fixed shaft 8 is rotatably connected to the connecting shaft 11. When the water flow in the connecting pipe 7 is high, the connecting pipe 7, along with the collar 23, sinks downwards, causing the fixed shafts 8 to move downwards synchronously. As the fixed shafts 8 move downwards, they push the linkage shaft 10. The linkage shaft 10, through the connecting shaft 11, pushes the arc-shaped pieces 9 to slide on the blind pipe 6, thereby extending each arc-shaped piece 9 and maintaining the stability of the arc-shaped piece 9 structure during periods of heavy rainfall. A spring 20 connects the upper end of the U-shaped locking block 12 to the collar 23. The U-shaped locking block 12 and the collar 23 are elastically connected by a spring 20. The stretchable spring 20 allows the collar 23 to continue to sink downwards under the action of gravity, while also being able to reset in time.

[0032] The driving mechanism includes two symmetrically arranged threaded shafts 14. The top plate 5 is fixedly connected to the drain pipe 3 via a support shaft 13, which is fixedly installed on the outer surface of the drain pipe 3. The two threaded shafts 14 are symmetrically rotated and installed below the top plate 5, and are located on the outer side of the drain pipe 3. The upper end of the inner sliding tube 4 is symmetrically fixedly connected to a connecting plate 15. The lower end of each of the two connecting plates 15 is provided with an arc-shaped block 16. The two threaded shafts 14 are threaded through the two arc-shaped blocks 16 respectively. A linkage mechanism is provided on the top plate 5. When the threaded shafts 14 rotate, the threaded shafts 14 thread through the arc-shaped blocks 16, and the two connecting plates 15 cooperate with each other, thus limiting the angle of the inner sliding tube 4. With the rotation of the threaded shafts 14, the inner sliding tube 4 can move up and down relative to each other.

[0033] The linkage mechanism includes a chain 18. A dual-head motor 17 is fixedly mounted on the lower surface of the top plate 5. One drive end of the dual-head motor 17 is fixedly connected to one of the threaded shafts 14, and the other drive end of the dual-head motor 17 is fixedly connected to a rotating shaft 25. A sprocket 19 is fixedly connected to both the upper end of the other threaded shaft 14 and the rotating shaft 25. The two sprockets 19 are connected together by the chain 18, and the sprockets 19 mesh with the chain 18. When the rotating shaft 25 rotates under the drive of the dual-head motor 17, it will drive the corresponding sprocket 19 to rotate. Since the two sprockets 19 are connected by the chain 18, the two threaded shafts 14 can rotate synchronously, thereby realizing the up and down movement of the inner slide tube 4.

[0034] An inclined filter screen (not shown) is installed inside the drain pipe 3, positioned above the connecting pipe 7. A support ring (not shown) is installed on the inner wall of the blind pipe 6. Since the blind pipe 6 has a hollow structure, the support ring prevents deformation of the blind pipe 6 after long-term use. The filter screen inside the drain pipe 3 blocks impurities in rainwater, preventing blockage inside the blind pipe 6. The wider plane of the linkage shaft 10 is vertically positioned, while the wider plane of the connecting shaft 11 is horizontally positioned. The connecting shaft 11 moves laterally, while the linkage shaft 10 moves vertically, facilitating movement within the soil.

[0035] This system is installed underground in the green space and buried in the soil. During normal rainy weather, rainwater on the road surface will directly seep down into the soil. The buried blind pipe 6 can collect the rainwater, which will then seep into the blind pipe 6 and be discharged into the city's sewer system.

[0036] When there is a lot of rain, the amount of rainwater on the ground exceeds the soil's ability to infiltrate water, thus activating the drive mechanism. The dual-head motor 17 drives the connected threaded shaft 14 to rotate through the drive end, and at the same time drives the rotating shaft 25 to rotate. The rotating shaft 25 drives the connected sprocket 19 to rotate. The two sprockets 19 rotate synchronously under the meshing connection of the chain 18, so that the two threaded shafts 14 rotate synchronously. As the threaded shaft 14 rotates, it drives the connected plate 15 to move up and down, so that the inner slide tube 4 can move downward.

[0037] After the inner sliding pipe 4 descends, it will be significantly lower than the ground water level. The surrounding rainwater will flow into the drain pipe 3. Due to the lower elevation of the drain pipe 3, the garbage and impurities in the rainwater will also flow into the drain pipe 3. A filter screen is installed inside the drain pipe 3, which blocks the garbage and impurities. The rainwater will continue to flow downwards. The drain pipe 3 is connected to the blind pipe 6 through the connecting pipe 7. The rainwater is finally discharged into the sewer through the connecting pipe 7 and the blind pipe 6, and there will be no problem of blockage due to impurities.

[0038] When there is a large amount of rainwater, the hollow structure of the blind pipe 6 is prone to deformation under external forces, which will affect the normal drainage of rainwater. When there is a lot of rainwater, the weight of the connecting pipe 7 will increase. The connecting pipe 7 will pull the U-shaped locking block 12 through the collar 23 to deform. The lower end of the U-shaped locking block 12 will drive the two fixed shafts 8 to move down. The fixed shafts 8 will drive the linkage shaft 10 to move. The linkage shaft 10 will push the arc-shaped pieces 9 to a distance, so that the arc-shaped pieces 9 can be dispersed and act as a barrier to prevent deformation under pressure, thereby maintaining the stability of the structure.

[0039] 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.
