Description

Technical Field

[0001] This application relates to the field of water supply and drainage devices, and in particular to a water-saving water supply and drainage device for green roofs of buildings. Background Technology

[0002] As we all know, rooftop greening is of great significance for increasing urban green space, improving the increasingly deteriorating human living environment, improving the situation of high-rise buildings in cities, improving the status quo of natural land and vegetation replaced by hard paving on many roads, improving the harm to humans caused by excessive deforestation, urban heat island effect and sandstorms caused by various air pollution, expanding human green space, building garden cities, improving people's living conditions, improving quality of life, and beautifying the urban environment and improving ecological effects.

[0003] In related technologies, utility model patent CN218933291U provides an energy-saving rooftop greening water supply and drainage device, including a support frame, a fixing frame, and sprinkler heads. A water supply tank is located at the upper end of the support frame. Water supply pipes are installed near both sides of one end of the fixing frame, and a drain pipe is installed at the lower end of the water supply pipes. A hexagonal connector is installed through one side of the water supply tank, and shaped pipes are installed through both sides of the hexagonal connector. In use, the water supply tank collects rainwater, which flows through the shaped pipes into the water supply pipes, then through the water supply pipes into the drain pipes, and finally through the drain pipes to the sprinkler heads, where it is sprayed out to irrigate the rooftop greening.

[0004] The aforementioned technologies have the following drawbacks: after the water in the water supply tank is sprayed out through the sprinkler head, there is still water remaining in the water supply pipe, resulting in a waste of water resources. Summary of the Invention

[0005] To address the issue of residual water in water supply pipes, this application provides a water-saving rooftop greening water supply and drainage device.

[0006] The water-saving rooftop greening water supply and drainage device provided in this application adopts the following technical solution:

[0007] A water-saving rooftop greening drainage device includes a support frame and a fixing frame. A water storage tank is installed on the support frame. Water outlet pipes are installed on both sides of the fixing frame, and drain pipes are installed on the water outlet pipes. A special-shaped pipe is installed on both sides of the water storage tank, and the special-shaped pipe is connected to the water outlet pipe. A sliding disc is installed inside the water outlet pipe and slides inside the water outlet pipe. The sliding disc abuts against the inner wall of the water outlet pipe. A control component is installed on the special-shaped pipe to control the sliding of the sliding disc.

[0008] By adopting the above technical solution, the reservoir can collect natural rainwater, enabling water resource utilization and improving water conservation. When water in the reservoir flows through the shaped pipe to the outlet pipe and is discharged through the outlet pipe, the operator can control the sliding plate via the control components. The sliding plate moves within the outlet pipe, pushing any remaining water back into the shaped pipe, reducing the possibility of water retention and minimizing water waste. As the sliding plate moves within the outlet pipe, it also cleans the inner wall of the pipe, improving its cleanliness and facilitating water flow.

[0009] Preferably, the shaped tube and the water storage tank are rotatably connected, and the support frame is provided with a rotating component and a fixing component. The rotating component is used to control the rotation of the shaped tube, and the fixing component is used to control the fixing of the shaped tube.

[0010] By adopting the above technical solution, when water remains in the outlet pipe, the operator can rotate the shaped pipe using the rotating component. The rotation of the shaped pipe will then rotate the outlet pipe. After the shaped pipe reaches the appropriate position, it will be fixed by the fixing component, thus securing the outlet pipe. Water in the outlet pipe will then slide down into the shaped pipe under its own gravity, reducing the possibility of water remaining in the outlet pipe and thus minimizing water waste. The rotation of the shaped pipe can also rotate the outlet pipe to the other side of the reservoir, facilitating irrigation of the other side of the reservoir via the drainage pipe.

[0011] Preferably, the water outlet pipe is inclined, with the end of the water outlet pipe near the fixing frame being lower than the end of the water outlet pipe near the shaped pipe, and the drain pipe is inclined, with the end of the drain pipe away from the water outlet pipe inclined toward the fixing frame.

[0012] By adopting the above technical solution, when the water in the reservoir flows to the outlet pipe, compared to a horizontal outlet pipe, the outlet pipe is inclined, creating a height difference between its two ends. This allows the water in the outlet pipe to have greater potential energy, facilitating its flow to the various drainage pipes. Due to the inclined design of the drainage pipes, when the outlet pipe rotates, the water in the drainage pipe can flow into the outlet pipe under its own gravity, and then flow through the outlet pipe into the irregularly shaped pipe, reducing the possibility of water remaining in the drainage pipe and further reducing water waste.

[0013] Preferably, the control component includes a control panel and a control rod. The control rod is rotatably connected to the water outlet pipe. One end of the control rod extends out of the shaped pipe. The control panel is installed on the end of the control rod that extends out of the shaped pipe. A sliding block is fixedly connected to the sliding plate. A sliding groove is formed on the inner wall of the water outlet pipe. The sliding block slides within the sliding groove. The control rod and the sliding plate are threaded together.

[0014] By adopting the above technical solution, since the sliding block slides within the sliding groove, the sliding groove can limit the sliding of the sliding block, thereby limiting the sliding of the sliding disc. When it is necessary to move the sliding disc, the operator can rotate the control panel. The rotation of the control panel can drive the rotation of the control rod, which in turn drives the sliding disc to move, thus enabling the sliding disc to slide within the water outlet pipe, facilitating the sliding disc to push the remaining water in the water pipe into the shaped pipe.

[0015] Preferably, the water outlet pipe includes a fixed part and a disassembly part. The fixed part is fixedly connected to the special-shaped pipe, and the disassembly part and the fixed part are detachably connected. The sliding groove is formed on the fixed part, and the control rod is rotatably connected to the disassembly part.

[0016] By adopting the above technical solution, the sliding plate slides inside the water outlet pipe to clean the inner wall of the water outlet pipe. The operator can disassemble the disassembly part and move it away from the fixed part. The movement of the disassembly part can drive the movement of the control rod, and the movement of the control rod can drive the sliding plate to slide out of the water outlet pipe, which makes it convenient for the operator to clean the sliding plate.

[0017] Preferably, the disassembly part is provided with a disassembly bolt, which passes through the disassembly part and the fixing part and is threadedly connected, and the disassembly bolt and the disassembly part abut against each other.

[0018] By adopting the above technical solution, when it is necessary to install the disassembly part, after moving the disassembly part to a suitable position, the disassembly bolt is moved and screwed in, so that the disassembly bolt passes through the threaded connection between the disassembly part and the fixing part. The disassembly bolt can limit the disassembly part, thereby realizing the installation of the disassembly part.

[0019] Preferably, the rotating assembly includes a connecting rod, a first rotating gear, a second rotating gear, a rotating rack, and a driving rod. The connecting rod is fixedly connected to the support frame, the first rotating gear is rotatably connected to the connecting rod, the second rotating gear is sleeved on the shaped tube, the second rotating gear and the shaped tube are fixedly connected, the rotating rack meshes with both the first and second rotating gears, and the driving rod is fixedly connected to the first rotating gear.

[0020] By adopting the above technical solution, when it is necessary to rotate the water outlet pipe, the operator can control the drive rod to rotate. The rotation of the drive rod can drive the rotation of the first rotating gear. The first rotating gear can drive the rotation of the second gear through the rotation of the rack. The rotation of the second gear can drive the rotation of the special-shaped pipe, thereby realizing the rotation of the water outlet pipe and facilitating the discharge of water from the water outlet pipe.

[0021] Preferably, the fixing component includes a fixing ratchet, a fixing pawl, and an auxiliary component. The fixing ratchet is sleeved on the shaped tube and fixedly connected to the shaped tube. The fixing pawl rotates relative to the water storage tank. The pawl tip is embedded between two adjacent ratchet teeth of the fixing ratchet. The auxiliary component is used to control the rotation of the fixing pawl.

[0022] By adopting the above technical solution, when the shaped tube rotates, the rotation of the shaped tube can drive the rotation of the fixed ratchet. When the shaped tube rotates to the appropriate position, the pawl tip of the fixed pawl is engaged between two adjacent ratchet teeth of the fixed ratchet. The fixed pawl can limit the rotation of the fixed ratchet, thereby limiting the rotation of the shaped tube, so that the water outlet pipe rotates to a position relative to the water storage tank. After the water outlet pipe rotates, the operator can use the control component to make the sliding plate slide, so that the water in the water outlet pipe can flow into the shaped tube and then into the water storage tank, reducing the waste of water resources.

[0023] Preferably, an auxiliary rod is fixedly connected to the water storage tank, the fixed pawl is rotatably connected to the auxiliary rod, the auxiliary component is an auxiliary torsion spring, and the auxiliary torsion spring is sleeved on the auxiliary rod.

[0024] By adopting the above technical solution, the auxiliary torsion spring can apply a thrust to the fixed pawl, causing the pawl tip to move toward the fixed ratchet, which facilitates the fixed pawl's limiting of the fixed ratchet.

[0025] Preferably, a drive plate is fixedly connected to the fixed pawl, a fixed rod is fixedly connected to the water storage tank, a sliding rod is provided on the fixed rod, the sliding rod and the fixed rod slide relative to each other, and the drive plate and the sliding rod abut against each other.

[0026] By adopting the above technical solution, when it is necessary to reverse the shaped tube, the operator can apply force to the drive plate, causing the drive plate to move the fixed pawl, releasing the fixed pawl from its limit on the fixed ratchet, thus facilitating the rotation of the shaped tube. After moving the drive plate, the operator can pull the sliding rod, moving it away from the fixed rod until it abuts against the drive plate. The sliding rod can then limit the drive plate, eliminating the need for the operator to apply manual force to the drive plate for an extended period, making it easier for the operator to rotate the shaped tube.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Through the design of the sliding disc and control components, the water storage tank can collect natural rainwater, enabling water resource utilization and improving water conservation. When water in the storage tank flows through the shaped pipe to the outlet pipe and is discharged, the operator can control the sliding disc to slide within the outlet pipe. The sliding disc pushes any remaining water in the outlet pipe back into the shaped pipe, reducing the possibility of water retention and minimizing water waste. As the sliding disc moves within the outlet pipe, it also cleans the inner wall of the pipe, improving its cleanliness and facilitating water flow.

[0029] 2. By incorporating a rotating and fixing assembly, when water remains in the outlet pipe, the operator can rotate the shaped pipe using the rotating assembly. This rotation of the shaped pipe, in turn, rotates the outlet pipe. Once the shaped pipe reaches the desired position, the fixing assembly secures it, thus fixing the outlet pipe in place. Water then flows down into the shaped pipe under its own weight, reducing the likelihood of water remaining in the outlet pipe and minimizing water waste. The rotation of the shaped pipe can also rotate the outlet pipe to the other side of the reservoir, facilitating irrigation of the other side of the reservoir via a drainage pipe.

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] This application discloses a water-saving rooftop greening water supply and drainage device, such as... Figure 1 As shown, the system includes a support frame 1, on which a water storage tank 11 is fixedly installed. The water storage tank 11 collects natural rainwater. Irregularly shaped pipes 3 are installed on both sides of the water storage tank 11. A water outlet pipe 21 is fixedly installed at the end of the irregularly shaped pipe 3 away from the water storage tank 11, and a drain pipe 22 is installed on the water outlet pipe 21. A fixing frame 2 is fixedly connected to the end of the water outlet pipe 21 away from the irregularly shaped pipe 3. Water in the water storage tank 11 flows through the irregularly shaped pipe 3 to the water outlet pipe 21, then through the water outlet pipe 21 to the drain pipe 22, and finally discharged through the drain pipe 22 to irrigate the rooftop greening. The fixing frame 2 provides support for the water outlet pipe 21.

[0039] like Figure 1As shown, the shaped pipe 3 and the water storage tank 11 are rotatably connected. The support frame 1 is equipped with a rotating component 6 and a fixing component 7. The rotating component 6 is used to control the rotation of the shaped pipe 3, and the fixing component 7 is used to control the fixing of the shaped pipe 3. The outlet pipe 21 is inclined, with the end of the outlet pipe 21 near the fixing frame 2 being lower than the end of the outlet pipe 21 near the shaped pipe 3. The drain pipe 22 is also inclined, with the end of the drain pipe 22 away from the outlet pipe 21 inclined towards the fixing frame 2. Due to the inclined arrangement of the outlet pipe 21, when water in the water storage tank 11 flows through the shaped pipe 3 to the outlet pipe 21, the height difference between the two ends of the outlet pipe 21 facilitates the flow of water from the outlet pipe 21 to each drain pipe 22, thus facilitating water irrigation. When the water in the reservoir 11 is used up, water still remains in the outlet pipe 21. The operator can rotate the special-shaped pipe 3 by rotating the component 6, thereby rotating the outlet pipe 21. The rotation of the outlet pipe 21 can drive the rotation of the drain pipe 22, so that the water in the outlet pipe 21 and the drain pipe 22 flows into the special-shaped pipe 3 and flows back into the reservoir 11 through the special-shaped pipe 3, reducing the possibility of water remaining in the outlet pipe 21 and reducing the waste of water resources.

[0040] like Figure 1 and 2 As shown, the rotating assembly 6 includes a connecting rod 61, a first rotating gear 62, a second rotating gear 63, a rotating rack 64, and a drive rod 65. The connecting rod 61 is fixedly connected to the support frame 1. The first rotating gear 62 is sleeved on the connecting rod 61, and the first rotating gear 62 and the connecting rod 61 are rotatably connected. The drive rod 65 is fixedly connected to the first rotating gear 62. The cross-section of the drive rod 65 is T-shaped, and the length direction of the drive rod 65 is consistent with the length direction of the connecting rod 61. The second rotating gear 63 is sleeved on the shaped tube 3, and the second rotating gear 63 and the shaped tube 3 are fixedly connected. The rotating rack 64 meshes with both the first rotating gear 62 and the second rotating gear 63. When it is necessary to rotate the outlet pipe 21, the operator can control the drive rod 65 to rotate. In actual operation, the operator can adapt the drive source of the drive rod 65 according to the specific situation, so that the drive rod 65 drives the first rotating gear 62 to rotate. The first rotating gear 62 drives the second rotating gear 63 to rotate through the rack 64. The rotation of the second gear drives the rotation of the special-shaped tube 3, thereby driving the rotation of the outlet pipe 21, so that the water in the outlet pipe 21 can flow into the special-shaped tube 3 under the action of gravity. The operator can control the drive rod 65 to rotate, so that the special-shaped tube 3 drives the outlet pipe 21 to rotate to the other side of the water storage tank 11. At this time, the fixing frame 2 still supports the outlet pipe 21, which facilitates the irrigation of the drainage pipe 22.

[0041] like Figure 1 and 2As shown, the first rotating gear 62 has a first positioning hole 621, and the support frame 1 has a second positioning hole 12. A positioning rod 622 is provided on the first rotating gear 62, and the positioning rod 622 has a T-shaped cross-section. Both the first positioning hole 621 and the second positioning hole 12 are for the positioning rod 622 to be inserted. When the operator drives the first rotating gear 62 to rotate via the drive rod 65, causing the first rotating gear 62 to rotate the water outlet pipe 21 to a vertical position, the operator can then insert the positioning rod 622 through the first positioning hole 621 into the second positioning hole 12. The positioning rod 622 can limit the first rotating gear 62, and the second positioning hole 12 can limit the positioning rod 622, thus positioning the first rotating gear 62 and the fixed frame 2 relative to each other. This allows the water outlet pipe 21 and the fixed frame 2 to be relatively fixed, facilitating the temporary fixation of the water outlet pipe 21 and allowing water in the water outlet pipe 21 to flow into the shaped pipe 3. When it is about to rain, the operator needs to first rotate the control drive rod 65 to make the water outlet pipe 21 vertical. At this time, the water storage tank 11 only needs to collect rainwater and does not need to irrigate. When the water outlet pipe 21 is vertical, the operator needs to pass the positioning rod 622 through the first positioning hole 621 and embed it into the second positioning hole 12 to fix the water outlet pipe 21.

[0042] like Figure 1 and 3 As shown, the fixing assembly 7 includes a fixing ratchet 71, a fixing pawl 72, an auxiliary component, and an auxiliary rod 74. The fixing ratchet 71 is sleeved on the shaped tube 3 and is located on the side of the second rotating gear 63 facing the water storage tank 11. The fixing ratchet 71 and the shaped tube 3 are fixedly connected. The auxiliary rod 74 is fixedly connected to the water storage tank 11, and the fixing pawl 72 is rotatably connected to the auxiliary rod 74. A drive plate 721 is fixedly connected to the fixing pawl 72, and the pawl tip of the fixing pawl 72 is embedded between two adjacent ratchet teeth of the fixing ratchet 71. The auxiliary component is used to control the rotation of the fixing pawl 72. The auxiliary component is an auxiliary torsion spring 73, which is mounted on the auxiliary rod 74. Under normal conditions, the auxiliary torsion spring 73 applies a thrust to the fixing pawl 72, causing the pawl tip of the fixing pawl 72 to move towards the fixing ratchet 71. When the shaped tube 3 rotates, its rotation drives the rotation of the fixed ratchet 71. The fixed pawl 72 limits the movement of the fixed ratchet 71, allowing the tip of the pawl 72 to engage between two adjacent teeth of the fixed ratchet 71 during rotation, thus suspending the shaped tube 3 and facilitating the flow of water from the outlet pipe 21. When it is necessary to continue rotating the shaped tube 3, the operator can apply force to the drive plate 721, causing the drive plate 721 to move the fixed pawl 72 away from the fixed ratchet 71, releasing the limitation of the fixed pawl 72 on the fixed ratchet 71, thereby facilitating the continued rotation of the shaped tube 3.

[0043] like Figure 3As shown, a fixed rod 8 is fixedly connected to the water storage tank 11. The fixed rod 8 is hollow and has a sliding rod 81 on it. The sliding rod 81 slides relative to the fixed rod 8. A groove is formed on the inner wall of the fixed rod 8, and a slider is fixedly connected to the outer wall of the sliding rod 81. The slider slides within the groove. When the operator pulls the drive plate 721 to move the fixed pawl 72 away from the fixed ratchet 71 and pulls out the sliding rod 81, the drive plate 721 abuts against the sliding rod 81. In actual operation, when the operator rotates the drive rod 65 to rotate the shaped tube 3, the shaped tube 3 drives the water outlet pipe 21 to rotate to the vertical direction. At this time, the pawl tip of the fixed pawl 72 abuts against the fixed ratchet 71, and the operator inserts the positioning rod 622 through the first positioning hole 621 into the second positioning hole 12. When the shaped tube 3 needs to rotate counterclockwise, the operator needs to apply force to the drive plate 721 to move the fixed pawl 72 away from the fixed ratchet 71, releasing the fixed pawl 72 from its position on the fixed ratchet 71. The fixed ratchet 71 remains relatively stationary under the action of the positioning rod 622. The operator then pulls the sliding rod 81 to make it abut against the drive plate 721. The sliding rod 81 can limit the drive plate 721, keeping the fixed pawl 72 in a state where it is not in contact with the fixed ratchet 71. Afterwards, the operator can remove the positioning rod 622 and rotate the shaped tube 3. Due to the sliding rod 81, the operator does not need to apply force to the drive plate 721 while simultaneously rotating the drive rod 65. Furthermore, the positioning rod 622 can temporarily limit the first rotating gear 62, reducing the possibility of the shaped tube 3 rotating autonomously when the fixed pawl 72 moves away from the fixed ratchet 71, thus facilitating operator control of the rotation of the shaped tube 3.

[0044] like Figure 4 As shown, the outlet pipe 21 includes a fixing part 211 and a disassembly part 212. The fixing part 211 is fixedly connected to the shaped pipe 3, and the fixing bracket 2 is fixedly connected to the fixing part 211. The disassembly part 212 and the fixing part 211 are detachably connected. The disassembly part 212 is provided with a disassembly bolt 2121, which passes through the disassembly part 212 and the fixing part 211 and is threadedly connected. The fixing part 211 is provided with a sliding disc 4, which slides within the fixing part 211. The axial direction of the sliding disc 4 is consistent with the length direction of the fixing part 211, and the peripheral wall of the sliding disc 4 abuts against the inner wall of the fixing part 211. The shaped pipe 3 is provided with a control component 5, which is used to control the sliding of the sliding disc 4.

[0045] like Figure 4 , 5As shown in Figure 6, a sliding groove 2111 is provided on the fixing part 211, and a sliding block 41 is fixedly connected to the sliding disk 4. The sliding block 41 slides within the sliding groove 2111, and the sliding groove 2111 can limit the sliding of the sliding block 41, thereby limiting the sliding of the sliding disk 4. The control component 5 includes a control disk 51 and a control rod 52. The length direction of the control rod 52 is consistent with the length direction of the fixing part 211. One end of the control rod 52 is rotatably connected to the disassembly part 212, and the other end passes through the fixing part 211 and extends out of the shaped tube 3. The control rod 52 and the sliding disk 4 are threadedly connected. The control disk 51 is installed on the end of the control rod 52 that extends out of the shaped tube 3. A hexagonal block 511 is fixedly connected to the control disk 51. A hexagonal groove 521 is provided on the end of the control rod 52 that extends out of the shaped tube 3, and the hexagonal groove 521 is for the hexagonal block 511 to be inserted. The operator can mount the control panel 51 onto the control lever 52. When the operator rotates the control panel 51, the rotation of the control panel 51 drives the rotation of the control lever 52, which in turn drives the sliding plate 4 to slide. This causes the sliding plate 4 to scrape the inner wall of the fixed part 211. The sliding plate 4 can also push water in the fixed part 211 into the shaped pipe 3 and clean the inner wall of the fixed part 211. The operator can disassemble the disassembly part 212 by rotating the disassembly bolt 2121, which moves away from the disassembly part 212 and releases the limitation of the disassembly bolt 212 on the disassembly part 212. The disassembly of the disassembly part 212 causes the control lever 52 to move away from the fixed part 211. The movement of the control lever 52 causes the sliding plate 4 to move away from the fixed part 211. The operator can then clean impurities from the surface of the sliding plate 4, facilitating its sliding within the fixed part 211 and cleaning the inner wall of the fixed part 211.

[0046] The implementation principle of a water-saving building rooftop greening water supply and drainage device according to an embodiment of this application is as follows:

[0047] The water storage tank 11 can collect natural rainwater, enabling water resource utilization and improving water conservation, thereby enhancing energy efficiency. Water in the water storage tank 11 flows through the shaped pipe 3 to the outlet pipe 21, then through the drainage pipe 22, and finally out through the drainage pipe 22 to irrigate the building's rooftop greenery. The operator can control the drive rod 65 to rotate, causing the drive rod 65 to drive the first rotating gear 62. The first rotating gear 62, through the rotating rack 64, drives the second rotating gear 63, which in turn drives the shaped pipe 3 to rotate. The rotation of the shaped pipe 3 drives the outlet pipe 21 to rotate to the other side of the water storage tank 11, increasing the irrigation area of ​​the drainage pipe 22.

[0048] When water remains in the outlet pipe 21, the operator can control the drive rod 65 to rotate, thereby rotating the outlet pipe 21. When the outlet pipe 21 rotates to the appropriate position, the water in the outlet pipe 21 slides down into the shaped pipe 3 under its own gravity, and the fixed pawl 72 can limit the fixed ratchet 71. At this time, the operator can install the control panel 51 and rotate the control panel 51. The rotation of the control panel 51 can drive the rotation of the control rod 52, and the rotation of the control rod 52 can drive the sliding plate 4 to slide. The sliding plate 4 can push the water in the outlet pipe 21, and the sliding plate 4 can clean the inner wall of the outlet pipe 21 and remove impurities from the inner wall of the outlet pipe 21.

[0049] The operator can disassemble the disassembly part 212 to move the control lever 52 away from the fixed part 211. The movement of the control lever 52 can drive the movement of the sliding plate 4, so that the sliding plate 4 moves away from the fixed part 211. The operator can clean the surface of the sliding plate 4 to facilitate the sliding of the sliding plate 4 in the fixed part 211, as well as the cleaning of the inner wall of the fixed part 211 by the sliding plate 4.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
