Description

Technical Field

[0001] This invention relates to the field of green building technology, specifically to a water utilization structure and method based on green building. Background Technology

[0002] Green buildings, also known as sustainable buildings, are structures and buildings designed to minimize their environmental impact and conserve resources throughout their lifespan through creative structural and functional designs. Green buildings offer excellent resource conservation benefits, such as planting landscaping plants on rooftops to better integrate the building with the natural environment and maintain comfortable indoor temperatures. In terms of water conservation and utilization, rainwater is collected in containers for storage and reuse.

[0003] As described in application number 202122427671.4, a roof rainwater collection and utilization device based on green building collects and stores rainwater after screening for impurities, thereby achieving water conservation and water resource utilization in green building. As described in application number 202020918682.5, a roof rainwater collection and utilization device based on green building ensures the cleanliness of stored water resources by filtering rainwater through multiple layers.

[0004] Based on the above data, it can be seen that conventional rainwater utilization structures in green buildings often pre-treat rainwater through filtration, and then store and reuse it as needed. This operation is relatively cumbersome and cannot be effectively integrated with rooftop landscaping plants. In other words, rooftop landscaping plants are often placed directly on the roof, which can easily damage or even kill them during heavy rainfall. Furthermore, when excessive rainwater is collected, it can only be discharged through overflow pipes, resulting in waste. Therefore, this paper proposes a water utilization structure and method based on green buildings. This method ensures normal rainwater storage while automatically protecting landscaping plants during heavy rainfall and automatically washing the building's exterior walls to maintain cleanliness, thus achieving efficient utilization of rainwater resources. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a water utilization structure and method based on green building, which solves the problems that conventional rainwater cannot be directly utilized after collection, and cannot effectively protect landscape plants in the event of heavy rainfall.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: a water utilization structure based on green building, including a water storage tank, with collection tanks connected to both the left and right sides of the water storage tank, and an obtuse-angled roof fixedly installed on the top of the water storage tank, the obtuse-angled roof being used to guide rainwater into the collection tanks, and the water storage tank and the collection tanks being connected through a slot.

[0009] The water storage tank is equipped with a slot adjustment component inside, and the obtuse-angled roof is equipped with a lifting adjustment component inside. The lifting adjustment component is used to drive the slot adjustment component to adjust the size of the slot. The collection box is equipped with a sudden rain trigger component inside. The sudden rain trigger component is used to drive the lifting adjustment component to adjust the height.

[0010] The telescopic end of the lifting adjustment component is fixedly installed with a landscape basin. The obtuse-angled roof is equipped with a sealing component inside, and the top of the obtuse-angled roof is provided with a through hole adapted to the landscape basin. The lifting adjustment component is used to drive the sealing component to seal the through hole. The water storage tank is equipped with a water spray component.

[0011] By adopting the above technical solution, a collection box is used as a transfer device to filter rainwater and store it in a water storage tank. With the cooperation of the slot adjustment device and the slot, the rainwater in the collection box can be rapidly raised in heavy rain. With the setting of the sudden rain trigger device, the lifting adjustment device can be controlled to store the landscape pot from the through hole into the obtuse-angled roof. Then, the through hole is sealed with a sealing device to effectively protect the landscape plants in heavy rain.

[0012] The invention is further configured such that: the lifting adjustment component includes a drive motor, the drive motor is fixedly installed at the bottom of the inner cavity of the water storage tank, the output end of the drive motor is fixedly connected to a single-threaded rod through a coupling, the top end of the single-threaded rod penetrates the water storage tank and extends into the interior of the obtuse-angle roof, wherein an auxiliary ring is sleeved and fixedly installed on the outer surface of the single-threaded rod, and the bottom of the auxiliary ring slides in contact with the top of the water storage tank to reduce the pressure on the drive motor; a U-shaped adjustment frame is sleeved and threadedly connected to the outer surface of the single-threaded rod, and an obtuse-angle bracket is fixedly installed on the top of the U-shaped adjustment frame, the obtuse-angle bracket being composed of two plates with an obtuse angle between them; an auxiliary rod is slidably installed through and on the front side of the bottom of the inner cavity of the U-shaped adjustment frame, and the bottom end of the auxiliary rod is fixedly connected to the top of the water storage tank;

[0013] The landscape basins are provided in a plurality of units, and the plurality of landscape basins are fixedly installed on the top of the obtuse-angle bracket in a rectangular array. A sealing sleeve is fitted and fixedly installed on the outer periphery of the landscape basins, and the top of the sealing sleeve is in contact with the top of the obtuse-angle roof cavity.

[0014] A water-proof sleeve is fixedly installed between the top and bottom of the inner cavity of the water storage tank, and the water-proof sleeve is located on the outer periphery of the drive motor.

[0015] By adopting the above technical solution, when the landscape pot is exposed on the obtuse-angled roof and there is rainy weather (excluding heavy rain), the water-proof sleeve is used to prevent rainwater from entering the interior of the obtuse-angled roof through the through hole. The setting of drive motor, single-head threaded rod, auxiliary rod and U-shaped adjustment frame realizes the lifting drive of obtuse-angle bracket, which facilitates the adjustment of the height of landscape pot.

[0016] The present invention is further configured such that: the slot adjustment component is provided in two sets, and each set of slot adjustment components includes an adjustment plate, a first toothed plate, a second toothed plate and a gear column. The gear column is rotatably installed at the bottom of the water storage tank cavity via a vertical rod. The adjustment plate and the first toothed plate are fixedly connected by a T-shaped plate. The first toothed plate and the second toothed plate are both used in conjunction with the gear column. The bottom of the first toothed plate is in contact with the bottom of the water storage tank cavity. A guide rod is slidably installed through the top of the T-shaped plate, and the two ends of the guide rod are fixedly connected to the top and bottom of the water storage tank cavity, respectively.

[0017] The slots are opened on the left and right sides of the inner cavity of the water storage tank. The two adjusting plates are in sliding contact with the left and right sides of the water storage tank on the side away from the first toothed plate, and a water passage is left between the bottom of the adjusting plate and the bottom of the inner cavity of the water storage tank. The second toothed plate is fixedly installed on the bottom of the obtuse angle bracket, and the top of the water storage tank is provided with an movable opening that matches the second toothed plate.

[0018] By adopting the above technical solution, the stability of the contact between the adjusting plate and the water storage tank is ensured by the coordinated arrangement of the adjusting plate, the T-plate, and the guide rod. With the cooperation of the first toothed plate, the second toothed plate, and the gear column, the size of the water passage can be adjusted. With the setting of the slot, the speed of rainwater flowing from the collection box to the water storage tank can be controlled. That is, when the water passage is small, it provides convenient conditions for the detection of rainstorms. After the rainstorm triggering device controls the start of the drive motor, the water passage is expanded, providing convenient conditions for the collection of rainwater.

[0019] The present invention is further configured such that a filter screen is provided on the top of the collection box;

[0020] The rain trigger includes a floating plate, which is disposed inside the collection box. A rain trigger button is fixedly installed at the bottom of the filter plate. The rain trigger button is used to control the rotation of the drive motor. A vertical rod is fixedly installed at the bottom of the inner cavity of the collection box, and the vertical rod passes through the floating plate.

[0021] Both sides of the obtuse-angled roof are connected to drainage pipes, which pass through the filter screen and extend into the inside of the collection box.

[0022] By adopting the above technical solution, and utilizing the combination of the floating board and the rain-triggered button, when the water passage is small and the rainfall is heavy, the rainwater in the collection box rises faster than the rainwater in the storage tank. That is, the rainwater in the collection box drives the floating board to rise, squeezing the rain-triggered button, thereby starting the drive motor and allowing the landscape pot to be stored in the obtuse-angled roof, thus achieving effective protection of the landscape pot in heavy rainfall.

[0023] The present invention is further configured such that: the sealing component is provided in two sets, and each set of sealing components includes two sealing plates. The front and rear sides of the two sealing plates are fixedly installed with sleeves. A stabilizing rod is slidably installed through the inside of the sleeve. One end of the stabilizing rod is fixedly installed on one side of the obtuse-angle roof cavity. A return spring is sleeved on the outer periphery of the stabilizing rod. The return spring is located between one side of the obtuse-angle roof cavity and the sleeve.

[0024] A pull rope is fixedly installed on one side of the sealing plate, and a fixing bracket adapted to the pull rope is fixedly installed on the top of the obtuse angle bracket. The top of the sealing plate is in contact with the top of the obtuse angle roof cavity. Four sealing strips are fixedly installed on the top of the obtuse angle roof cavity. The sealing strips and the sealing plate are respectively set on both sides of the through hole.

[0025] By adopting the above technical solution and using a pull rope as a delayed drive structure, when the obtuse-angle bracket pulls the landscape pot completely into the obtuse-angle roof, the pull rope tightens, thereby driving the sleeve to move along the stabilizing rod. While squeezing the return spring, it seals the through hole, preventing rainwater from continuously seeping into the obtuse-angle roof. When the obtuse-angle bracket pulls the landscape pot up, the return spring drives the sleeve to move along the stabilizing rod, exposing the through hole and providing convenient conditions for the landscape pot to be moved out of the obtuse-angle roof.

[0026] The present invention is further configured such that: the water spray component includes a spray assembly, a cleaning assembly, a transfer assembly, and a water pump; the water pump is fixedly installed at the top of the inner cavity of the water storage tank; the input end of the water pump is connected to an inlet pipe, and one end of the inlet pipe passes through the water storage tank and extends into the interior of the water storage tank; the output end of the water pump is connected to the transfer assembly through an outlet pipe; the transfer assembly is used to control the water pump to supply water to the spray assembly or the cleaning assembly.

[0027] The invention is further configured such that: the spray assembly includes a transfer box and two obtuse-angled water pipes, each obtuse-angled water pipe being a straight pipe bent, with the angle between the straight pipes after the bend being an obtuse angle; the transfer box is fixedly installed on the top of the obtuse-angled roof; both obtuse-angled water pipes are fixedly installed on the top of the obtuse-angled roof via connecting plates; the two obtuse-angled water pipes are respectively located on the front and rear sides of the transfer box; both the front and rear sides of the transfer box are connected to the two obtuse-angled water pipes via pipes; watering holes are provided on both the front and rear sides of the obtuse-angled water pipes; a water guide pipe is connected to the bottom of the transfer box; the bottom end of the water guide pipe passes through the obtuse-angled roof and the obtuse-angled bracket in sequence and extends into the interior of the U-shaped adjusting frame; a curved pipe is fitted around the outer periphery of the water guide pipe and slidably installed thereon; the curved pipe is fixedly installed inside the U-shaped adjusting frame via connecting plates.

[0028] The adapter assembly includes an adapter cylinder, which is fixedly installed at the bottom of the inner cavity of the water storage tank. An adapter spring is fixedly installed at the bottom of the inner cavity of the adapter cylinder, and a piston plate is fixedly installed at the top of the adapter spring. The piston plate cooperates with the adapter cylinder. The top of the adapter cylinder penetrates the water storage tank and extends into the interior of the obtuse-angled roof. The bottom end of the curved tube penetrates the adapter cylinder and extends into the interior of the adapter cylinder. A sealing post adapted to the curved tube is fixedly installed at the top of the piston plate. One end of the water inlet pipe is connected to the adapter cylinder and is positioned above the piston plate.

[0029] By adopting the above technical solution, and utilizing the piston plate and the adapter spring, when the piston plate is not subjected to compressive force, the water in the inlet pipe can only flow from the adapter cylinder to the curved pipe, and then through the water guide pipe, the transfer box and the obtuse angle water pipe, and finally spray out through the watering hole to water the landscape pot.

[0030] The present invention is further configured such that: the cleaning assembly includes a water supply pipe, one end of which is connected to the adapter cylinder and is disposed on one side of the piston plate; the other end of which passes through the water storage tank and extends to one side of the collection tank; the water supply pipe is fixedly connected to one side of the collection tank via a connecting plate; a cleaning pipe is connected to the bottom of the water supply pipe located on one side of the collection tank; and a cleaning hole is provided on the side of the cleaning pipe near the collection tank.

[0031] A water pump trigger button is fixedly installed at the bottom of the inner cavity of the adapter tube, and the water pump trigger button is used to control the water pump to start.

[0032] An overflow pipe is connected to one side of the collection box, and the overflow pipe is located below the rain trigger button.

[0033] By adopting the above technical solution, with the U-shaped adjusting frame in place, ensuring the connection between the water pipe and the curved pipe, in the event of heavy rainfall, the U-shaped adjusting frame drives the curved pipe to descend along the transition cylinder. In conjunction with the sealing column, the curved pipe is sealed while the piston plate is squeezed to disengage from the water delivery pipe, so that the water in the transition cylinder can only be discharged through the water delivery pipe. Furthermore, with the water pump trigger button set, the water pump is directly started, transporting the rainwater in the storage tank to the water delivery pipe, and then spraying it out through the cleaning holes on the cleaning device to clean the exterior wall of the building, thus achieving effective utilization of the excess rainwater in the storage tank.

[0034] This invention also discloses a water utilization method based on green building, specifically including the following steps:

[0035] Step 1, Normal Water Storage: During non-heavy rainy weather, rainwater falls on the obtuse-angled roof to water the landscape pots. After being filtered by the filter screen, the rainwater falls into the collection box. The rainwater then enters the water storage tank through the trough and water passage for storage. Excess rainwater is discharged through the overflow pipe.

[0036] Step 2, Rainstorm Protection: In the event of heavy rain, rainwater falls rapidly into the collection box. The rate at which rainwater accumulates in the collection box exceeds the rate at which rainwater enters the storage tank through the water passage. As a result, the rainwater level in the collection box rises rapidly, causing the floating plate to rise and press the rainstorm trigger button. The rainstorm trigger button controls the drive motor to rotate, which in turn drives the single-headed threaded rod to rotate. This causes the U-shaped adjusting frame to move the obtuse-angle bracket downwards, which in turn moves the landscape pot downwards, allowing the landscape pot to move into the interior of the obtuse-angled roof.

[0037] Step 3, Sealing and Protection: As the obtuse-angle bracket moves downward, the pull rope is pulled downward. When the landscape pot is retracted into the obtuse-angle roof, the pull rope is taut. As the obtuse-angle bracket continues to descend, the pull rope pulls the sealing plate. During this process, the sealing plate drives the sleeve to slide along the stabilizer bar, compressing the return spring until the sealing plate moves to contact the sealing strip. At this point, the sealing plate completes the sealing of the through hole, and the drive motor stops rotating.

[0038] Step 4, Flow Expansion and Adjustment: During the descent of the obtuse angle bracket, the second toothed plate moves downward. After the second toothed plate passes through the movable opening, it drives the gear column to rotate. The gear column drives the first toothed plate to rise. The first toothed plate drives the T-shaped plate to raise the adjustment plate, expanding the water passage and accelerating the speed at which rainwater in the collection box flows to the storage tank.

[0039] Step 5, Wall Cleaning: As the U-shaped adjusting frame moves downward, it drives the curved tube downward along the water guide pipe and the adapter cylinder. During this process, the adapter cylinder is fitted onto the sealing column. As the curved tube continues to descend, it squeezes the piston plate. After the piston plate squeezes the adapter spring, it squeezes the water pump trigger button. At this time, the piston plate descends and exposes the water delivery pipe. The water pump trigger button controls the water pump to start. The water pump delivers the rainwater stored in the water tank to the water outlet pipe through the water inlet pipe. The water outlet pipe delivers the stored rainwater to the adapter cylinder, and then through the water delivery pipe to the cleaning pipe. The water is then sprayed out from the cleaning port to clean the wall.

[0040] The invention is further configured to include: after rainy weather, controlling the drive motor to reverse, the drive motor drives the single-head threaded rod to reverse, causing the U-shaped adjustment frame to move the obtuse angle bracket upward. During the process, the reset spring pushes the sleeve to move along the stabilizer rod. After the through hole is exposed, the obtuse angle bracket drives the landscape pot to move through the through hole to the top of the obtuse angle roof until the sealing sleeve contacts the top of the inner cavity of the obtuse angle roof.

[0041] When it is time to water the landscape pots in sunny weather, turn on the water pump control switch. The water pump will transport the rainwater stored in the water tank to the water outlet pipe through the water inlet pipe. The water outlet pipe will then transport the stored rainwater to the transfer cylinder. At this time, the piston plate will block the water delivery pipe. The stored rainwater will flow through the curved pipe to the guide pipe. Subsequently, the stored rainwater will flow through the transfer box to the obtuse-angled water pipe and spray out from the pouring hole to water the landscape pots.

[0042] (III) Beneficial Effects

[0043] This invention provides a water utilization structure and method based on green building. It has the following beneficial effects:

[0044] (1) This invention uses a collection box as a transfer device to filter rainwater and store it in a water storage tank. By using the trough adjustment device and the trough in combination, the rainwater in the collection box can be rapidly raised in heavy rain. With the setting of the sudden rain trigger device, the lifting adjustment device can be controlled to store the landscape pot from the through hole into the obtuse-angle roof. Then, the through hole is sealed by the sealing device to effectively protect the landscape plants in heavy rain. At the same time, with the setting of the water spray device, the rainwater in the water storage tank is sprayed out to clean the exterior wall of the building, realizing the effective utilization of the excess rainwater in the water storage tank.

[0045] (2) In this invention, when the landscape basin is exposed to the obtuse-angled roof and there is rainy weather (not heavy rain), the water-proof sleeve is used to prevent rainwater from entering the obtuse-angled roof through the through hole. The obtuse-angle bracket is driven to lift by the drive motor, single-head threaded rod, auxiliary rod and U-shaped adjustment frame, so as to facilitate the adjustment of the height of the landscape basin.

[0046] (3) The present invention ensures the stability of the contact between the adjusting plate and the water storage tank by using the coordinated arrangement of the adjusting plate, the T-shaped plate and the guide rod. With the cooperation of the first toothed plate, the second toothed plate and the gear column, the size of the water passage can be adjusted. With the setting of the slot, the speed of rainwater flowing from the collection box to the water storage tank can be controlled. That is, when the water passage is small, it provides convenient conditions for the detection of rainstorms. After the rainstorm triggering device controls the start of the drive motor, the water passage is expanded, providing convenient conditions for the collection of rainwater.

[0047] (4) By utilizing the combination of the floating plate and the rain-triggered button, when the water passage is small and the rain is heavy, the rainwater in the collection box rises faster than the rainwater in the storage tank. That is, the rainwater in the collection box drives the floating plate to rise and squeezes the rain-triggered button, thereby starting the drive motor and allowing the landscape pot to be stored in the obtuse-angled roof, thus achieving effective protection of the landscape pot in the case of heavy rain.

[0048] (5) By using a pull rope as a delayed driving structure, when the obtuse angle bracket drives the landscape pot to be completely retracted into the obtuse angle roof, the pull rope is tightened, which in turn drives the sleeve to move along the stabilizing rod, squeezing the return spring and sealing the through hole, preventing rainwater from continuously seeping into the obtuse angle roof from the through hole. When the obtuse angle bracket drives the landscape pot to rise, the return spring drives the sleeve to move along the stabilizing rod, exposing the through hole, providing convenient conditions for the landscape pot to be moved out of the obtuse angle roof.

[0049] (6) By utilizing the piston plate and the adapter spring, when the piston plate is not subjected to pressure, the water in the inlet pipe can only flow from the adapter cylinder to the curved pipe, and then through the water guide pipe, the transfer box and the obtuse angle water pipe, and then sprayed out through the watering hole to water the landscape pot.

[0050] (7) Under the premise of ensuring the connection between the water pipe and the curved pipe by setting the U-shaped adjustment frame, the U-shaped adjustment frame drives the curved pipe to descend along the transition cylinder when the rain is heavy. With the setting of the sealing column, the curved pipe is blocked while the piston plate is squeezed to get out of the limit on the water supply pipe. This allows the water in the transition cylinder to be discharged through the water supply pipe. With the setting of the water pump trigger button, the water pump is started directly to transport the rainwater in the water storage tank to the water supply pipe. Then, it is sprayed out through the cleaning hole on the cleaning device to clean the exterior wall of the building, thus realizing the effective utilization of the excess rainwater in the water storage tank.

[0061] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0062] Please see Figure 1-9 The present invention provides the following two technical solutions:

[0063] Example 1

[0064] A water utilization structure based on green building includes a water storage tank 1, two collection tanks 2, an obtuse-angled roof 3, a slot adjustment component 5, a lifting adjustment component 6, a sudden rain trigger component 7, a sealing component 8, and a landscape basin 9.

[0065] As a preferred embodiment, the rain trigger 7 is installed in the collection box 2. Specifically, a filter plate 26 is installed on the top of the collection box 2, and the rain trigger 7 includes a float plate 27, which is installed inside the collection box 2. A rain trigger button 28 is fixedly installed at the bottom of the filter plate 26. The rain trigger button 28 is used to control the operation of the lifting adjustment component 6. An overflow pipe 55 is connected to one side of the collection box 2 and is located below the rain trigger button 28. A vertical rod 29 is fixedly installed at the bottom of the inner cavity of the collection box 2 and passes through the float plate 27. Drain pipes 30 are connected to both the left and right sides of the obtuse-angled roof 3. The drain pipes 30 pass through the filter plate 26 and extend into the interior of the collection box 2.

[0066] As explained in detail, by using the float plate 27 and the upright rod 29, when the liquid level in the collection box 2 reaches the point where the float plate 27 is driven to squeeze the rain trigger button 28, the rain trigger button 28 can be activated.

[0067] As a preferred embodiment, to facilitate the detection of sudden rainfall, the water storage tank 1 and the collection tank 2 are connected by a slot 4, and the slot adjustment component 5 is used to adjust the slot 4. Specifically, there are two sets of slot adjustment components 5, and each set of slot adjustment components 5 includes an adjustment plate 19, a first toothed plate 20, a second toothed plate 21, and a gear column 22. A water passage is left between the bottom of the adjustment plate 19 and the bottom of the inner cavity of the water storage tank 1. The water passage is the necessary path for rainwater to enter the water storage tank 1 after passing through the slot 4. When the water passage is small and the rainfall is heavy, i.e., heavy rain or torrential rain, the water level in the collection tank 2 will rise faster than the water level in the water storage tank 1, so that the floating plate 27 can squeeze the sudden rainfall trigger button 28.

[0068] As a preferred embodiment, the lifting adjustment component 6 includes a drive motor 12. The drive motor 12 is a servo motor, capable of forward and reverse rotation, and electrically connected to an external power source. It is controlled via a rain trigger button 28 and an external control switch. The drive motor 12 is fixedly installed at the bottom of the inner cavity of the water tank 1. To achieve waterproof protection for the drive motor 12, a water-proof sleeve 18 is fixedly installed between the top and bottom of the inner cavity of the water tank 1, and the water-proof sleeve 18 is located on the outer periphery of the drive motor 12. The output end of the drive motor 12 is fixedly connected to a coupling. A single-threaded rod 13 has its top end penetrating through the water storage tank 1 and extending into the interior of the obtuse-angled roof 3. A U-shaped adjusting frame 14 is fitted and threaded onto the outer surface of the single-threaded rod 13, and an obtuse-angled bracket 15 is fixedly installed on the top of the U-shaped adjusting frame 14. An auxiliary rod 16 is slidably installed through the front side of the bottom of the inner cavity of the U-shaped adjusting frame 14, and the bottom end of the auxiliary rod 16 is fixedly connected to the top of the water storage tank 1. As a detailed explanation, the obtuse-angled bracket 15 can be adjusted by controlling the forward and reverse rotation of the drive motor 12.

[0069] As a preferred embodiment, the top of the obtuse-angled roof 3 is provided with a through hole 10 that is compatible with the landscape basin 9. Several landscape basins 9 are provided and are fixedly installed on the top of the obtuse-angled bracket 15 in a rectangular array. A sealing sleeve 17 is fitted and fixedly installed on the outer periphery of the landscape basin 9. The top of the sealing sleeve 17 contacts the top of the inner cavity of the obtuse-angled roof 3, so that the landscape basin 9 can be adjusted up and down with the obtuse-angled bracket 15, which provides convenience for the storage and protection of the landscape basin 9 in the event of heavy rain.

[0070] Furthermore, to ensure that rainwater in collection box 2 can quickly flow into water storage tank 1 in the event of heavy rainfall, gear column 22 is rotatably installed at the bottom of the inner cavity of water storage tank 1 via a vertical rod. Adjustment plate 19 and first toothed plate 20 are fixedly connected by T-shaped plate 23. Both the first toothed plate 20 and the second toothed plate 21 are used in conjunction with gear column 22, and the bottom of the first toothed plate 20 is in contact with the bottom of the inner cavity of water storage tank 1. A guide rod 24 is slidably installed through the top of T-shaped plate 23, and the two ends of the guide rod 24 are fixedly connected to the top and bottom of the inner cavity of water storage tank 1, respectively. The slot 4 is opened. On the left and right sides of the inner cavity of the water storage tank 1, the two adjusting plates 19 are in sliding contact with the left and right sides of the water storage tank 1 on the side away from the first toothed plate 20, respectively. The second toothed plate 21 is fixedly installed at the bottom of the obtuse angle bracket 15, and the top of the water storage tank 1 is provided with an movable opening 25 that matches the second toothed plate 21. That is, when the obtuse angle bracket 15 drives the landscape pot 9 to descend, the second toothed plate 21 drives the gear column 22 to rotate, which causes the first toothed plate 20 to drive the T-shaped plate 23 to raise the adjusting plate 19, thereby increasing the adjustment of the water passage and ensuring that rainwater flows quickly from the collection box 2 into the water storage tank 1.

[0071] As a preferred embodiment, in order to achieve effective sealing control of the through hole 10, two sets of sealing components 8 are provided, and each set of sealing components 8 includes two sealing plates 31. Sleeves 32 are fixedly installed on both the front and rear sides of the two sealing plates 31. A stabilizing rod 33 is slidably installed through the inside of the sleeve 32. One end of the stabilizing rod 33 is fixedly installed on one side of the inner cavity of the obtuse-angle roof 3. A return spring 34 is sleeved on the outer periphery of the stabilizing rod 33. The return spring 34 is located between one side of the inner cavity of the obtuse-angle roof 3 and the sleeve 32. A pull rope 35 is fixedly installed on one side of the sealing plate 31. A fixing bracket 36 adapted to the pull rope 35 is fixedly installed on the top of the obtuse-angle bracket 15. The top of the sealing plate 31 is in contact with the top of the inner cavity of the obtuse-angle roof 3. Four sealing strips 37 are fixedly installed on the top of the inner cavity of the obtuse-angle roof 3. The sealing strips 37 and the sealing plate 31 are respectively located on both sides of the through hole 10.

[0072] As explained in detail, when the obtuse-angle bracket 15 pulls the landscape pot 9 completely into the obtuse-angle roof 3, the pull rope 35 is tightened, which in turn drives the sleeve 32 to move along the stabilizer 33. While squeezing the return spring 34, the through hole 10 is blocked to prevent rainwater from continuously seeping into the obtuse-angle roof 3. When the obtuse-angle bracket 15 pulls the landscape pot 9 up, the return spring 34 drives the sleeve 32 to move along the stabilizer 33, exposing the through hole 10 and providing convenient conditions for the landscape pot 9 to be removed from the obtuse-angle roof 3.

[0073] In this embodiment, automatic detection of heavy rainfall is achieved, thereby controlling the start of the drive motor 12 to store the landscape basin 9 inside the obtuse-angled roof 3 for protection. At the same time, the sealing plate 31 is driven to seal the through hole 10 to prevent rainwater from continuously entering the obtuse-angled roof 3 through the through hole 10. Simultaneously, the water passage is enlarged and adjusted to accelerate the flow of rainwater from the collection box 2 to the water storage tank 1.

[0076] As a preferred embodiment, the sprinkler assembly 38 includes a transfer box 44 and two obtuse-angled water pipes 45. The transfer box 44 is fixedly installed on the top of the obtuse-angled roof 3. The two obtuse-angled water pipes 45 are both fixedly installed on the top of the obtuse-angled roof 3 through connecting plates. The two obtuse-angled water pipes 45 are respectively located on the front and rear sides of the transfer box 44. The front and rear sides of the transfer box 44 are connected to the two obtuse-angled water pipes 45 through pipes. Watering holes are opened on the front and rear sides of the obtuse-angled water pipes 45. A water guide pipe 46 is connected to the bottom of the transfer box 44. The bottom end of the water guide pipe 46 passes through the obtuse-angled roof 3 and the obtuse-angled bracket 15 in sequence and extends into the interior of the U-shaped adjusting frame 14. A curved pipe 47 is fitted around the outer periphery of the water guide pipe 46 and slidably installed. The curved pipe 47 is fixedly installed inside the U-shaped adjusting frame 14 through connecting plates.

[0077] As a preferred embodiment, in order to achieve on / off control of water supply in the curved pipe 47, the adapter assembly 40 includes an adapter cylinder 48, which is fixedly installed at the bottom of the inner cavity of the water storage tank 1.

The bottom of the water supply pipe 52 located on one side of the collection tank 2 is connected to a cleaning pipe 53, and a cleaning hole is opened on the side of the cleaning pipe 53 near the collection tank 2.

[0079] As a preferred solution, in order to enable the automatic start of the water pump 41, a water pump trigger button 54 is fixedly installed at the bottom of the inner cavity of the adapter cylinder 48. The water pump trigger button 54 is used to control the start of the water pump 41.

[0080] The advantage of Embodiment 2 over Embodiment 1 is that the watering pipe layout of the landscape pot 9 is realized by using the adapter tube 48, curved pipe 47, water guide pipe 46, transfer box 44 and obtuse angle water pipe 45. When the rain is heavy, the curved pipe 47 is blocked by the piston plate 50, adapter spring 49 and sealing column 51 when the U-shaped adjustment frame 14 descends, ensuring the connection between the adapter tube 48 and the water delivery pipe 52. Under the setting of the water pump trigger button 54, the water pump 41 is directly started. With the setting of the cleaning pipe 53 and cleaning hole, the exterior wall of the building is cleaned at the same time, while avoiding the situation of excessive rainwater accumulation in the water storage tank 1.

[0081] A water utilization method based on green building specifically includes the following steps:

[0082] Step 1, Normal water storage: In rainy weather without heavy rain, rainwater falls on the obtuse-angled roof 3 and waters the landscape pot 9. After being filtered by the filter screen 26, the rainwater falls into the collection box 2. The rainwater enters the water storage tank 1 through the slot 4 and the water passage for storage. Excess rainwater is discharged through the overflow pipe 55.

[0083] Step 2, Rainstorm Protection: In the event of heavy rain, rainwater falls rapidly into the collection box 2. The rate at which rainwater accumulates in the collection box 2 is greater than the rate at which rainwater enters the water storage tank 1 through the water passage. As a result, the rainwater level in the collection box 2 rises rapidly, causing the floating plate 27 to rise and press the rainstorm trigger button 28. The rainstorm trigger button 28 controls the drive motor 12 to rotate, which in turn drives the single-headed threaded rod 13 to rotate. This causes the U-shaped adjusting frame 14 to move the obtuse angle bracket 15 downwards, which in turn moves the landscape pot 9 downwards, allowing the landscape pot 9 to move into the interior of the obtuse angle roof 3.

[0084] Step 3, sealing and protection: As the obtuse angle bracket 15 moves downward, the pull rope 35 is pulled downward. When the landscape pot 9 is retracted into the obtuse angle roof 3, the pull rope 35 is taut. As the obtuse angle bracket 15 continues to descend, the pull rope 35 pulls the sealing plate 31 to move. During this process, the sealing plate 31 drives the sleeve 32 to slide along the stabilizer 33, squeezing the return spring 34 until the sealing plate 31 moves to contact the sealing strip 37. At this time, the sealing plate 31 completes the sealing of the through hole 10, and the drive motor 12 stops rotating.

[0085] Step 4, Flow Expansion and Adjustment: During the descent of the obtuse angle bracket 15, the second toothed plate 21 is driven to move downward. After the second toothed plate 21 passes through the movable opening 25, it drives the gear column 22 to rotate. The gear column 22 drives the first toothed plate 20 to rise. The first toothed plate 20 drives the T-shaped plate 23 to raise the adjusting plate 19, thereby expanding the water passage and accelerating the flow of rainwater from the collection box 2 to the storage tank 1.

[0086] Step 5, Wall Cleaning: As the U-shaped adjusting bracket 14 moves downward, it drives the curved tube 47 to move downward along the water guide pipe 46 and the adapter cylinder 48. During this process, the adapter cylinder 48 is fitted onto the sealing column 51. As the curved tube 47 continues to descend, it squeezes the piston plate 50. After the piston plate 50 squeezes the adapter spring 49, it squeezes the water pump trigger button 54. At this time, the piston plate 50 descends and exposes the water delivery pipe 52. The water pump trigger button 54 controls the water pump 41 to start. The water pump 41 delivers the rainwater stored in the water storage tank 1 to the water outlet pipe 43 through the water inlet pipe 42. The water outlet pipe 43 delivers the stored rainwater to the adapter cylinder 48, and then through the water delivery pipe 52 to the cleaning pipe 53, from which it is sprayed out to clean the wall.

[0087] Furthermore, after rainy weather, the drive motor 12 is reversed, and the drive motor 12 drives the single-headed threaded rod 13 to move in the opposite direction, so that the U-shaped adjusting frame 14 drives the obtuse angle bracket 15 to move upward. During the process, the return spring 34 pushes the sleeve 32 to move along the stabilizing rod 33. After the through hole 10 is exposed, the obtuse angle bracket 15 drives the landscape pot 9 to move through the through hole 10 to the top of the obtuse angle roof 3 until the sealing sleeve 17 contacts the top of the inner cavity of the obtuse angle roof 3.

[0088] When it is sunny and the landscape pot 9 needs to be watered, the control switch of the water pump 41 is turned on. The water pump 41 delivers the rainwater stored in the water storage tank 1 to the water outlet pipe 43 through the water inlet pipe 42. The water outlet pipe 43 delivers the stored rainwater to the transfer cylinder 48. At this time, the piston plate 50 blocks the water delivery pipe 52. The stored rainwater flows through the curved pipe 47 to the water guide pipe 46. Then, the stored rainwater flows through the transfer box 44 to the obtuse angle water pipe 45 and sprays out from the pouring hole to water the landscape pot 9.

9. A green building based water utilization method, characterized by: Specifically, the following steps are included: Step 1, Normal water storage: During rainy weather when there is no heavy rain, rainwater falls on the obtuse-angled roof (3) to water the landscape pot (9). After being filtered by the filter screen (26), the rainwater falls into the collection box (2). The rainwater enters the water storage tank (1) through the slot (4) and the water passage for storage. Excess rainwater is discharged through the overflow pipe (55). Step 2, Rainstorm Protection: In the event of heavy rain, rainwater falls rapidly into the collection box (2). The accumulation speed of rainwater in the collection box (2) is greater than the speed at which rainwater enters the water storage tank (1) through the water passage. The rainwater level in the collection box (2) rises rapidly, and the floating plate (27) rises and presses the rainstorm trigger button (28). The rainstorm trigger button (28) controls the drive motor (12) to rotate. The drive motor (12) drives the single-head threaded rod (13) to rotate, causing the U-shaped adjustment frame (14) to move the obtuse angle bracket (15) downward. The obtuse angle bracket (15) moves the landscape pot (9) downward, causing the landscape pot (9) to move into the interior of the obtuse angle roof (3). Step 3, sealing and protection: During the downward movement of the obtuse angle bracket (15), the pull rope (35) is pulled downward. When the landscape pot (9) is retracted into the obtuse angle roof (3), the pull rope (35) is taut. As the obtuse angle bracket (15) continues to descend, the pull rope (35) pulls the sealing plate (31) to move. During the process, the sealing plate (31) drives the sleeve (32) to slide along the stabilizer (33) and squeeze the reset spring (34) until the sealing plate (31) moves to contact the sealing strip (37). At this time, the sealing plate (31) completes the sealing of the through hole (10), and the drive motor (12) stops rotating. Step 4, Flow Expansion Adjustment: During the descent of the obtuse angle bracket (15), the second toothed plate (21) is driven to move downward.

Step 5, Wall Cleaning: As the U-shaped adjusting bracket (14) moves downward, it drives the curved tube (47) downward along the water guide pipe (46) and the adapter cylinder (48). During this process, the adapter cylinder (48) is fitted onto the sealing column (51). As the curved tube (47) continues to descend, it squeezes the piston plate (50). After the piston plate (50) squeezes the adapter spring (49), it triggers the water pump trigger button (54). When squeezed, the piston plate (50) descends and the water supply pipe (52) is exposed. The water pump trigger button (54) controls the water pump (41) to start. The water pump (41) transports the rainwater stored in the water storage tank (1) to the water outlet pipe (43) through the water inlet pipe (42).

During the process, the reset spring (34) pushes the sleeve (32) to move along the stabilizer (33). After the through hole (10) is exposed, the obtuse angle bracket (15) drives the landscape pot (9) to move through the through hole (10) to the top of the obtuse angle roof (3) until the sealing sleeve (17) contacts the top of the inner cavity of the obtuse angle roof (3). When it is necessary to water the landscape pot (9) in sunny weather, start the control switch of the water pump (41). The water pump (41) transports the rainwater stored in the water storage tank (1) to the water outlet pipe (43) through the water inlet pipe (42). The water outlet pipe (43) transports the stored rainwater to the transfer tube (48). At this time, the piston plate (50) blocks the water delivery pipe (52).
