Abstract
Description
Technical Field
[0001] This utility model belongs to the field of garden drainage technology, and in particular relates to a silt-prevention garden road drainage structure. Background Technology
[0002] Existing drainage structures for garden paths often employ simple grating and straight-line pipe designs, which are prone to siltation. Rainwater carrying mud, fallen leaves, and other debris easily clogs drain outlets, leading to poor drainage and requiring frequent manual cleaning, which is labor-intensive. In some cases, silt can even flow into downstream pipes, clogging the drainage system. This not only affects the aesthetics of the garden but can also cause flooding during the rainy season, adversely impacting plant growth and pedestrian safety. Therefore, there is an urgent need for a garden path drainage structure that effectively prevents siltation, provides stable drainage, requires less frequent manual cleaning, and is easy to maintain. Utility Model Content
[0003] In view of this, in order to solve the problems of easy siltation, poor drainage and inconvenient maintenance of existing garden road drainage structures, this utility model proposes a silt-proof garden road drainage structure with reasonable structural design, avoiding debris accumulation, stable drainage and easy maintenance.
[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows:
[0005] A silt-prevention drainage structure for garden roads includes:
[0006] The anti-fouling unit includes a base, a barrier cage, and a sedimentation ring chamber. The upper end of the base is open and has a hollow internal structure. A water passage hole is opened at the center of the bottom, and a sedimentation groove is provided around the outer side of the water passage hole on the upper surface of the bottom. The barrier cage is detachably installed in the inner cavity of the base and covers the outer ring of the sedimentation groove. The sedimentation ring chamber is detachably disposed in the sedimentation groove.
[0007] A grille cover, which is detachably mounted on the base, has a center-upward conical structure.
[0008] The water inlet pipe has its upper end detachably connected to the water passage hole; the side wall of the water inlet pipe has a drain hole, and a filter screen is provided on the drain hole;
[0009] A drain pipe, one end of which is detachably connected to the drain hole.
[0010] As a primary flood control structure, the grating cover allows rainwater to enter the base through its conical structure. The grating cover's design prevents larger debris (such as leaves and trash) from entering the drainage system, providing initial interception. Its upward-pointing conical shape helps guide water flow, reducing the impact on the grating while increasing the interception area and enhancing the ability to intercept large debris, preventing debris buildup on the grating surface. After entering the base, rainwater first passes through a barrier cage, which further intercepts debris via vertical grating plates. A sedimentation ring chamber, located in the base's sedimentation groove, collects heavy particles like silt and sand from the rainwater, acting as a sedimentation unit. After being treated by the grating cover and flood control unit, the rainwater enters the inlet pipe through a water passage at the center of the base's bottom. The drain holes on the side wall of the inlet pipe are equipped with filters to further filter residual impurities in the rainwater, ensuring that the water entering the drain pipe contains fewer impurities and preventing blockage of the downstream drainage system. Because all parts are detachable, cleaning and maintenance are easy.
[0011] Furthermore, the bottom upper surface of the base is provided with an annular slot with internal threads around the outer ring of the deposition groove; the barrier cage includes an annular bottom ring, a plurality of vertical grid plates arranged circumferentially along the upper surface of the annular bottom ring, and an upper cover covering the top of the vertical grid plates; the annular bottom ring is provided with external threads, and the annular bottom ring is detachably installed in the annular slot by the threads; the upper cover is provided with a plurality of elongated openings.
[0012] The barrier cage is installed by threaded connection to the base, which allows it to be firmly installed on the base while being easy to disassemble and maintain. Maintenance personnel can easily disassemble the barrier cage to clean the silt and debris deposited in the sedimentation chamber. The vertical grid plate can not only block debris, but also disperse water flow, which is conducive to the deposition of silt and other debris mixed in the water flow in the sedimentation chamber.
[0013] Furthermore, the upper end of the base is provided with a docking plate extending horizontally outward; the grille cover includes an annular mounting plate, a circular upper plate suspended above the center of the annular mounting plate, and a plurality of inclined grille plates arranged circumferentially along the annular mounting plate, the upper end of the inclined grille plates being connected to the circular upper plate, and the lower end face of the annular mounting plate being detachably docked with the docking plate.
[0014] The detachable connection between the grille cover and the base facilitates regular cleaning and ensures unobstructed drainage.
[0015] Furthermore, there are two drain holes, which are staggered in the circumferential and vertical directions; the outer wall of the water inlet pipe is provided with a docking seat at the outer edge of the drain hole, and one end of the drain pipe is detachably connected to the docking seat by a thread.
[0016] The staggered design of the drain holes can evenly distribute the water flow, achieve multi-point diversion, and improve the overall drainage efficiency; the threaded connection design allows the drain pipe to be easily disassembled, facilitating regular cleaning of the filter screen and the sediment inside the drain pipe, ensuring the smooth flow of the drainage system.
[0017] Furthermore, it also includes a sedimentation tank, and the lower end of the water inlet pipe is an open structure that is detachably connected to the inner cavity of the sedimentation tank.
[0018] Sedimentation ponds are used to collect sediments such as mud and sand mixed in with water flow.
[0019] Furthermore, the sedimentation tank includes an outer tank body and a sedimentation box disposed within the outer tank body; the outer tank body is a cuboid structure with an internal cavity, and its upper end face is provided with an insertion hole; the upper end of the sedimentation box is open, and the open end is located below the insertion hole; the lower end of the water inlet pipe is detachably inserted into the insertion hole.
[0020] The sediment entering with the water flow will settle in the sedimentation tank due to its own gravity, avoiding blockage of the water inlet pipe and reducing the frequency of regular cleaning.
[0021] Furthermore, the upper surface of the outer pool is provided with an openable and closable sealing cover; the volume of the outer pool is larger than that of the sedimentation tank, and the sedimentation tank can be moved from below the insertion hole to below the sealing cover and removed from there; a handle is provided on the inner wall of the sedimentation tank.
[0022] During cleaning, open the sealing cover, pull the sedimentation tank directly under the original sealing cover, and remove the sedimentation tank for cleaning using the handle.
[0023] Furthermore, it also includes a sewage pipe; the lower end of the water inlet pipe is a sealed structure, and a sewage outlet is provided on the lower side wall of the pipe, and the sewage pipe and the sewage outlet are detachably connected.
[0024] The silt and sand that enters with the water flow settles at the bottom of the inlet pipe and can be removed by the drain pipe. The drain pipe is connected to the sewage system, and during regular cleaning, the silt and sand impurities in the drain pipe are extracted by the sewage pump of the sewage system.
[0025] Furthermore, the outer wall of the water inlet pipe is also provided with a docking seat at the outer edge of the sewage outlet, and one end of the sewage outlet pipe is detachably connected to the docking seat by a thread.
[0026] Compared with existing technologies, the anti-siltation garden road drainage structure of this utility model has the following advantages:
[0027] The anti-siltation garden road drainage structure of this utility model has a reasonable structural design. Through multi-stage interception (grid cover → barrier cage → filter screen), gravity settling (sedimentation ring chamber) and modular detachable structure, it achieves efficient siltation prevention, convenient cleaning and stable drainage. The combination of physical interception and settling reduces the risk of pipe blockage and has strong anti-blockage performance. Each component can be disassembled independently, resulting in high cleaning efficiency and low maintenance cost. Attached Figure Description

[0039] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0040] Example 1
[0041] like Figures 1 to 4 As shown, a silt-prevention garden road drainage structure includes a silt-prevention unit 1, a grid cover 2, an inlet pipe 3, a drain pipe 4, and a sedimentation tank 5.
[0042] The containment unit 1 includes a base 6, a barrier cage 7, and a sedimentation ring chamber 8. The upper end of the base 6 is open and has a hollow internal structure. A water passage hole 9 is opened at the center of its bottom. A sedimentation groove 10 is provided around the water passage hole 9 on the upper surface of the bottom. An annular slot 11 with internal threads is provided around the outer ring of the sedimentation groove 10 on the upper surface of the bottom. A horizontally extending docking plate 12 is provided at the upper end of the base 6. The barrier cage 7 is detachably installed in the inner cavity of the base 6 and covers the outer ring of the sedimentation groove 10. The barrier cage 7 includes an annular bottom ring 13, multiple vertical grid plates 14 arranged circumferentially along the upper surface of the annular bottom ring 13, and a top cover 15 covering the top of the vertical grid plates 14. The annular bottom ring 13 has external threads and is detachably installed in the annular slot 11 through the threads. Multiple elongated openings 16 are opened on the top cover 15. The sedimentation ring chamber 8 is detachably located in the sedimentation groove 10.
[0043] The grille cover 2 is mounted on the base 6. The grille cover 2 is a cone-shaped structure with the center pointing upward. The grille cover 2 includes an annular mounting plate 17, a circular upper plate 18 suspended above the center of the annular mounting plate 17, and a plurality of inclined grille plates 19 arranged around the annular mounting plate 17. The upper end of the inclined grille plates 19 is connected to the circular upper plate 18, and the lower end face of the annular mounting plate 17 is detachably connected to the docking plate 12.
[0044] The upper end of the water inlet pipe 3 is detachably connected to the water passage hole 9; a drain hole is provided on the side wall of the water inlet pipe 3, and a filter screen 20 is provided on the drain hole; there are two drain holes, which are staggered in the circumferential and vertical directions; a docking seat 21 is provided on the outer side wall of the water inlet pipe 3 at the outer edge of the drain hole;
[0045] One end of the drain pipe 4 is detachably connected to the mating seat 21 via a thread;
[0046] The sedimentation tank 5 includes an outer tank body 22 and a sedimentation box 23 located inside the outer tank body 22. The outer tank body 22 is a cuboid structure with an internal cavity, and its upper end face is provided with an insertion hole and an openable sealing cover 24. The upper end of the sedimentation box 23 is open, and the open end is located below the insertion hole. A handle 25 is provided on the inner side wall of the sedimentation box 23. The volume of the outer tank body 22 is larger than that of the sedimentation box 23, and the sedimentation box 23 can be moved from below the insertion hole to below the sealing cover 24 and removed from there. The lower end of the water inlet pipe 3 is an open structure and can be detachably inserted into the insertion hole.
[0047] The working principle of the anti-siltation garden road drainage structure described in this embodiment is as follows:
[0048] Rainwater and carried debris (such as fallen leaves and mud) first pass through the grid cover 2. The conical structure guides the water flow to the center to concentrate and reduce surface overflow. The inclined grid plate 19 intercepts large debris (such as branches and plastic bags) to prevent them from entering the inner cavity of the base 6.
[0049] After the water flows into the cavity of the base 6, the barrier cage 7 further intercepts the incoming debris, and the heavier components such as mud and sand in the water partially settle into the sedimentation ring chamber 8 due to gravity.
[0050] After preliminary filtration, the water flows through the water hole 9 into the inlet pipe 3. After being intercepted by the filter screen 20, the water flows through the drain hole into the drain pipe 4 and is finally discharged into the municipal pipe network or recycling system. The intercepted residual debris and sediment are deposited in the sedimentation tank 23 under the action of gravity.
[0051] When cleaning is required, open the grid cover 2 and the barrier cage 7, take out the full sedimentation ring chamber 8, clean it and put it back; when the sedimentation tank 23 is full, open the sealing cover 24 of the outer tank body 22, move the sedimentation tank 23 from below the insertion hole to below the sealing cover 24, and take out the sedimentation tank 23 directly through the handle 25 on the inner side wall for cleaning, and put it back after cleaning.
[0052] Example 2
[0053] like Figure 5 As shown, based on Example 1, the difference from Example 1 is that no sedimentation tank 5 is set up, but a sewage pipe 26 is used instead; the lower end of the water inlet pipe 3 is a sealed structure, and a sewage outlet 27 is opened on the lower side wall. The outer side wall of the water inlet pipe 3 is also provided with a docking seat 31 at the outer edge of the sewage outlet 27. One end of the sewage pipe 26 is detachably connected to the docking seat 21 by a thread.
[0054] The intercepted residual debris and silt are deposited at the lower end of the inlet pipe 3 under the action of gravity, and then discharged by the sewage system connected to the sewage pipe 26.
[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
