Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of green roofs, and in particular to a green roof with a water-guiding and filtering structure. Background Technology
[0002] A green roof with a filtering and water-guiding structure refers to a roof where a structural layer with filtering and water-guiding functions is laid on the waterproof layer of a building roof or the top slab of an underground project, and then covered with planting soil and plants to achieve waterproofing, heat preservation, heat insulation and ecological environmental protection.
[0003] Existing green roofs typically use a combination of geogrids and geotextiles for the filter layer, filtering and protecting the planting soil to prevent clogging of the drainage system. The drainage structure, using materials such as plastic drainage boards, allows for rapid water drainage or storage, ensuring the roof doesn't accumulate water. However, after prolonged use, both the filter layer and drainage structure require cleaning. This usually involves manual cleaning using tools to reach into the drainage structure, disassembling the drainage structure, or replacing the filter layer—all methods that are labor-intensive and time-consuming. Utility Model Content
[0004] To facilitate cleaning and improve work efficiency, this utility model provides a green roof with a filter and water guiding structure.
[0005] The present invention provides a green roof with a filtering and water guiding structure, which adopts the following technical solution:
[0006] A green roof with a filtering and water guiding structure includes a green roof connected to a drainage pipe, a planting box placed on the green roof, a first vent hole on the bottom plate of the planting box, a water guiding box installed below the planting box, a second vent hole on the top plate of the water guiding box communicating with the first vent hole, a water guiding channel inside the water guiding box, the second vent hole communicating with the water guiding channel, sliding grooves on both sides of the water guiding channel, clamping blocks slidingly connected in the sliding grooves, and a filter screen detachably installed between the opposing clamping blocks.
[0007] By adopting the above technical solution, when encountering rainy weather or watering plants, excessive water will cause the soil to be unable to absorb it, resulting in excess water. At this time, the excess water will seep into the water guide tank through the first and second ventilation holes, and the filter screen can provide a second layer of barrier against the soil. When too much sediment accumulates in the water guide tank, the water guide tank needs to be cleaned. Simply pull the filter screen out of the water guide tank, remove the clamping block, and clean it. This makes it easy to clean after prolonged use, reduces manual cleaning time, and improves work efficiency.
[0008] Optionally, a filter plate is vertically fixed to one end of the filter screen, and a scraper is vertically fixed to the other end of the filter screen.
[0009] Optionally, a U-shaped opening is provided on the side of the clamping block near the filter screen, the filter screen is placed in the U-shaped opening, a locking rod is threaded on the clamping block, the locking rod passes through the U-shaped opening, and a pressure plate for pressing and fixing the filter screen is rotatably connected to the end of the locking rod.
[0010] Optionally, the pressure plate has a protrusion on the side near the filter screen.
[0011] Optionally, a guide wheel is rotatably mounted on the bottom of the clamping block.
[0012] Optionally, a rotating block is rotatably mounted on the outer wall of the clamping block, and the rotating block is rolled and connected in the slide groove.
[0013] Optionally, a rotating groove is provided on the outer wall of the clamping block, a limit ring is fixedly connected in the rotating groove by bolts, and a rotating block is rotatably connected in the rotating groove, the rotating block passing through the limit ring and extending out of the rotating groove.

[0020] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 The present invention will be described in further detail below.
[0021] This utility model discloses a green roof with a water-guiding and filtering structure.
[0022] Reference Figures 1-3The green roof with a filter and water guiding structure includes a green roof 1. Multiple drainage pipes are fixedly installed on both sides of the green roof 1, and each drainage pipe is connected to the green roof 1. Two sets of planting boxes 2 are placed on the green roof 1. The two sets of planting boxes 2 are arranged symmetrically. Each set of planting boxes 2 contains three planting boxes 2. Each planting box 2 has several first ventilation holes 3 at its bottom. A water guiding box 4 is fixedly connected to the bottom of the planting box 2 by several bolts. Several second ventilation holes 5 are opened at the top of the water guiding box 4. The second ventilation holes 5 are connected to the first ventilation holes 3.
[0023] Reference Figures 2-5 The water guide tank 4 has three water guide grooves 6. The second vent 5 is connected to the three water guide grooves 6. Each water guide groove 6 has a sliding groove 7 on both sides. The two sliding grooves 7 are symmetrically arranged. Each sliding groove 7 has a set of clamping blocks 8 slidably connected in it. Each set of clamping blocks 8 contains multiple clamping blocks 8. The two sets of clamping blocks 8 correspond one to one. One side of the clamping block 8 has a rotating groove 9. The rotating groove 9 is fixedly connected to a limit ring 10 by multiple bolts. The rotating block 11 is rotatably connected in the rotating groove 9. The rotating block 11 passes through the limit ring 10 and extends out of the rotating groove 9. The other side of the clamping block 8 has a U-shaped opening.
[0024] Reference Figure 5 The clamping block 8 has a blind hole at the top of its U-shaped opening, into which a screw-connected locking rod 12 is inserted. A pressure plate 13 is provided at the bottom of the locking rod 12, with the top of the pressure plate 13 rotatably connected to the bottom of the locking rod 12. Several protrusions are provided at the bottom of the pressure plate 13. A filter screen 14 is provided between the two sets of clamping blocks 8, with both sides of the filter screen 14 inserted into the corresponding U-shaped openings of the two sets of clamping blocks 8.
[0025] Reference Figure 4 and Figure 5 The clamping block 8 has a U-shaped opening at its bottom. A guide wheel 15 is fixedly installed inside the U-shaped opening of each clamping block 8. A filter plate 16 is fixedly connected to one end of the filter screen 14, and a scraper 17 is fixedly connected to the other end of the filter screen 14. The sidewall of the scraper 17 fits snugly against the sidewalls of the two clamping blocks 8. In use, the guide wheel 15 allows the clamping block 8 to slide more easily out of the slide groove 7. The filter plate 16 blocks sediment from entering the water guide groove 6, preventing sediment from clogging the drain pipe over time. Simultaneously with removing the filter screen 14, the scraper 17 moves in the same direction, scraping out the sediment from the water guide groove 6, thus cleaning the water guide groove 6 while removing the filter screen 14.
[0026] When using, place the planting box 2 and the water guide box 4 on the planting roof 1. When placing the two sets of planting boxes 2, the side of the water guide box 4 with the filter plate 16 should face the drain pipes on both sides of the planting roof 1. Insert the filter screen 14 into the U-shaped openings of the two sets of clamping blocks 8 on both sides. Press the locking rod 12 down to move the pressure plate 13 down to clamp the filter screen 14. The protrusion can increase the friction. Then plant the soil and plants in the planting box 2. The first ventilation hole 3 is used to ensure the oxygen in the soil.
[0027] When it rains or when watering plants, excessive water can prevent the soil from absorbing it, resulting in excess water. This excess water will seep into the water tank 4 through the first vent 3 and the second vent 5. The second vent 5 acts as a first layer of barrier against soil erosion and ensures that the excess water flows smoothly into the water tank 4. Subsequently, the excess water will flow into the water channel 6 through the filter screen 14, which acts as a second layer of barrier against soil erosion.
[0028] When the water in the water channel 6 reaches a certain amount, it will flow out of the water channel 6 through the filter plate 16 and be discharged along the drain pipes on both sides of the green roof 1. When too much sediment accumulates in the water channel 6, the water channel 6 needs to be cleaned. At an appropriate time, the clamping block 8 is removed along the slide 7 towards the drain pipe.
[0029] Because the distance between the planting box 2 and the side wall of the planting roof 1 and the distance between the two planting boxes 2 are too narrow to directly remove the entire filter screen 14, each time two clamping blocks 8 are pulled out, these two clamping blocks 8 need to be rotated to be perpendicular to the ground. This will cause the part of the filter screen 14 that has been pulled out to also be perpendicular to the ground, so that the filter screen 14 can be removed vertically little by little. This solves the problem of insufficient space and ensures that the filter screen 14 can be removed smoothly, making it convenient to clean the filter screen 14.
[0030] When the clamping block 8 is rotated, the rotating block 11 will rotate in the corresponding rotating groove 9. The limiting ring 10 plays a limiting role. This water guiding structure ensures normal water guiding work and can also filter during the water guiding process. It can be easily cleaned after long-term use, reducing manual cleaning time and improving work efficiency.
[0031] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
