Description

Technical Field

[0001] This utility model relates to the field of drainage technology for green roofs, specifically a new type of drainage component for green roofs. Background Technology

[0002] A green roof is a roof where soil or loose materials such as sawdust or vermiculite are laid on top of the waterproof layer, and plants are planted on top of it. This type of roof provides insulation and requires drainage components to be installed below the plants so that rainwater can drain out.

[0003] Patent document CN212078463U discloses a drainage system for a green roof, which includes a support base with a square water storage groove on its surface. The inner walls of both sides of the water storage groove have slots for engaging with a matching support bracket. The edges of the support bracket fit into the slot openings. Several water outlet pipes are horizontally arranged side-by-side on the middle surface of the support bracket. One end of each water outlet pipe is connected to a liquid guide pipe. One end of each liquid guide pipe is connected to a water injection valve at the bottom of the support base via a flexible hose. The bottom of the water injection valve is connected to an external water source. This green roof drainage system, with its support base, water storage groove, and support bracket, facilitates the installation of the entire device. The water storage groove collects excess water to avoid waste and also prevents the soil from becoming loose after overflowing.

[0004] However, the aforementioned published literature on a green roof drainage system mainly considers the problem that the existing drainage system cannot collect and reuse excess water. However, this drainage system collects excess water through a water storage tank, resulting in a limited amount of water that can be collected. When the plants on the green roof are short of water, they cannot be effectively replenished in a timely manner.

[0005] In view of this, it is necessary to develop a new type of drainage component for green roofs, so as to quickly and effectively replenish water when plants on green roofs are short of water. Utility Model Content

[0006] The purpose of this utility model is to provide a new type of drainage component for green roofs, so as to solve the technical problem mentioned in the background art that the drainage system collects excess water through a water storage tank, resulting in limited water collection and inability to effectively replenish water when the green roof is short of water.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel drainage component for green roofs, comprising: a drainage shell, wherein a water storage component is installed inside the drainage shell, the water storage component is used to store rainwater, the water storage component includes a water storage tank, an inlet, a water collection shell, and a connecting shell, the water storage tank is installed inside the drainage shell, the inlet is opened at the top of the water storage tank, the water collection shell is installed at the top of the drainage shell, and the connecting shell is installed through the bottom of the water collection shell, and the connecting shell is located inside the inlet.

[0008] Preferably, the drainage shell has symmetrical through openings on both sides of its inner wall.

[0009] Preferably, connecting shells are symmetrically installed on both sides of the drainage shell, and drainage pipes are symmetrically installed through the bottom of the connecting shells.

[0010] Preferably, an installation plate is installed on one side of the connecting shell, a transfer pump is installed on one side of the installation plate, a transfer pipe is installed at the output end of the transfer pump, a connecting pipe is installed at the input end of the transfer pump, and one end of the connecting pipe is connected through to one side of the water storage tank.

[0011] Preferably, a filter plate is installed on the top of the water collection shell, and a moisturizing pad is installed on the top of the water collection shell through the filter plate.

[0012] Preferably, the top of the moisturizing pad has an S-shaped mounting groove, the inside of which is fitted with a water supply pipe, and the outside of the water supply pipe has multiple water outlet holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The water storage tank in this utility model is used to collect and store rainwater. After the rainwater in the storage tank is stored, the excess rainwater is discharged through the gap between the inlet and the connecting shell. Since the top of the storage tank is a sloping surface that slopes to both sides, the rainwater enters through the sloping surface and is discharged into the connecting shell. Finally, it is discharged through the drain pipe installed through the bottom of the connecting shell. When the rainwater is discharged through the drainage components, the storage tank stores the rainwater. When it is necessary to replenish the water for the green plants on the green roof, the rainwater stored in the storage tank can be transferred and used, which can save water resources and make the green roof more environmentally friendly.

[0015] 2. In this utility model, the water supply pipe is installed in an "S" shape in the mounting groove on the top of the moisturizing pad, so that the rainwater is discharged into the moisturizing pad through the water outlet on the outside of the water supply pipe. The moisturizing pad locks in the rainwater and comes into contact with the roots of the green plants on the green roof, thereby providing water to the green plants. Moreover, the moisturizing pad makes the replenished water more even, and avoids the rainwater not being able to provide water to all the green plants. Attached Figure Description

[0024] Please see Figure 1 and Figure 2 A new type of drainage component for green roofs;

[0025] It includes: a drainage shell 1 and a water storage component. The water storage component is installed inside the drainage shell 1. The water storage component is used to store rainwater. The water storage component includes a water storage tank 2, an inlet 3, a water collection shell 11, and a docking shell 12. The water storage tank 2 is installed inside the drainage shell 1. The inlet 3 is opened at the top of the water storage tank 2. The water collection shell 11 is installed at the top of the drainage shell 1. The docking shell 12 is installed through the bottom of the water collection shell 11 and is located inside the inlet 3. Through openings 4 are symmetrically opened on the inner walls of both sides of the drainage shell 1. Connecting shells 5 are symmetrically installed on both sides of the drainage shell 1. Drainage pipes 6 are symmetrically installed through the bottom of the connecting shells 5.

[0026] The drainage shell 1 provides space for excess rainwater to drain from the green roof and also provides an installation location for the water storage components. Rainwater from the top of the green roof enters the water collection shell 11. The bottom of the water collection shell 11 is an arc-shaped structure that can be installed inside the drainage shell 1, allowing all the rainwater entering the water collection shell 11 to enter the interior of the water storage tank 2 through the connecting shell 12. The connecting shell 12 is located inside the inlet 3. After the rainwater in the water storage tank 2 is fully stored, the excess rainwater is discharged through the gap between the inlet 3 and the connecting shell 12. Since the top of the water storage tank 2 is a sloping surface that slopes to both sides, the rainwater enters through the sloping surface into the through-hole 4 and is discharged into the connecting shell 5. Finally, it is discharged through the drainage pipe 6 installed through the bottom of the connecting shell 5. While the rainwater is being discharged through the drainage components, the water storage tank 2 stores the rainwater. When it is necessary to replenish the water for the green plants on the green roof, the rainwater stored in the water storage tank 2 can be transferred and used, which saves water resources and makes the green roof more environmentally friendly.

[0027] Please see Figure 1 , Figure 3 and Figure 4 A new type of drainage component for green roofs;

[0028] The device includes a transfer pump 8 and a moisturizing pad 14. A mounting plate 7 is installed on one side of the connecting shell 5, and a transfer pump 8 is installed on one side of the mounting plate 7. A transfer pipe 10 is installed at the output end of the transfer pump 8, and a connecting pipe 9 is installed at the input end of the transfer pump 8. One end of the connecting pipe 9 is connected to one side of the water storage tank 2. A filter plate 13 is installed on the top of the water collection shell 11, and a moisturizing pad 14 is installed on the top of the water collection shell 11 through the filter plate 13. An S-shaped mounting groove 15 is opened on the top of the moisturizing pad 14, and a water supply pipe 16 is installed inside the mounting groove 15. Multiple water outlet holes 17 are opened on the outside of the water supply pipe 16.

[0029] Mounting plate 7 provides an installation position for transfer pump 8. After being powered on, transfer pump 8 converts electrical energy into kinetic energy, causing the input connection pipe 9 to draw rainwater stored in water storage tank 2 for use. Transfer pump 8 transfers the drawn rainwater through transfer pipe 10 to water supply pipe 16. Transfer pipe 10 and water supply pipe 16 are snap-fit ​​connected. Since water supply pipe 16 is installed in an "S" shape in the mounting groove 15 on the top of moisturizing pad 14, the transferred rainwater is discharged into moisturizing pad 14 through the water outlet 17 on the outside of water supply pipe 16. The moisturizing pad 14 locks in the rainwater and comes into contact with the roots of the green plants on the green roof, thereby providing water to the green plants. Moreover, the moisturizing pad 14 makes the replenished water more even, preventing rainwater from not providing water to all the green plants. Filter plate 13 plays a filtering role, reducing the amount of other impurities carried by rainwater entering water storage tank 2.

[0030] The working principle is as follows: First, the drainage component is installed on the green roof. The green plants on the green roof are planted on the top of the moisture-retaining pad 14 through the cultivation layer, so that the roots of the green plants can contact the moisture-retaining pad 14. When it rains, some of the rainwater is in the moisture-retaining pad 14 and some flows downward. It is filtered through the filter plate 13 and enters the water collection shell 11. Then it enters the water storage tank 2 through the docking shell 12. When the water storage tank 2 is full, the rainwater is discharged through the inlet 3. The discharged rainwater passes through the through-hole 4 and the connecting shell 5, and finally is discharged through the drain pipe 6. The rainwater in the water storage tank 2 can be transferred to the moisture-retaining pad 14 for use by the transfer pump 8.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
