Description

Technical Field

[0001] This application relates to the field of garden system technology, and in particular to a multifunctional rainwater storage and drainage garden system. Background Technology

[0002] Rain gardens are shallow, naturally formed or artificially excavated green spaces used to collect and absorb rainwater from rooftops or the ground. Through the combined action of plants and soil, the rainwater is purified and gradually infiltrates the soil, replenishing groundwater or supplying urban water uses such as landscaping and toilets. It is an ecologically sustainable stormwater control and rainwater utilization facility.

[0003] Regarding the aforementioned technologies, because the soil is constantly infiltrating, it is not conducive to the garden system's own water storage. When there is less rain, the soil will be short of water and additional water will be needed for irrigation. Summary of the Invention

[0004] In order to store rainwater in the soil for plant absorption during periods of low rainfall, this application provides a multifunctional rainwater storage and drainage garden system.

[0005] The multifunctional rainwater storage and drainage garden system provided in this application adopts the following technical solution:

[0006] A multifunctional rainwater storage and drainage garden system includes a rainwater collector, a drainage board, and a drainage well. Both the drainage board and the drainage well are mounted on the rainwater collector. The drainage well has an inlet and a first outlet, and a cover plate. A rotating screw is rotatably connected inside the drainage well, extending out of the cover plate. A lifting valve is threaded onto the rotating screw, and the lifting valve is slidably connected to the drainage well and closes the inlet. The first outlet communicates with the rainwater collector. A planting board is mounted on the drainage board, with permeable holes and a planting layer.

[0007] By adopting the above technical solution, when it rains, rainwater flows through the planting layer to the planting board and then into the drainage board through the permeable holes. After the drainage board and the planting board are filled with water, the rainwater is then stored in the planting layer, thus completing the storage of rainwater. This allows rainwater to be stored in the soil for plants to absorb when there is less rain.

[0008] When there is too much water in the planting layer, rotate the screw. The rotating screw will drive the lifting valve to rise and open the water inlet. The rainwater will flow into the drainage well through the water inlet and then into the rainwater collector from the first drainage outlet for storage.

[0009] Optionally, a first valve plate for closing the first drain outlet is rotatably installed inside the drainage well. A connecting rod is connected to the lifting valve. A lifting block is slidably installed on the connecting rod. The lifting block is hinged to a rotating rod. The rotating rod is hinged to the first valve plate.

[0010] By adopting the above technical solution, when the lifting valve rises, the lifting valve drives the connecting rod to rise, the connecting rod drives the lifting block to move, the sliding rod drives the rotating rod to rotate, and the rotating rod drives the first valve plate to open, thereby achieving the effect that when the water inlet opens, the first drain outlet also opens at the same time.

[0011] Optionally, the linkage rod is provided with a lifting sleeve, the sliding rod is slidably disposed inside the lifting sleeve, the sliding rod is provided with a float plate, the drainage well has a second drainage outlet, the second drainage outlet is connected to the rainwater collector, the well cover plate has a water inlet hole, the drainage well is hinged to a second valve plate for closing the second drainage outlet via a rotating shaft, the rotating shaft is provided with a torsion spring, the rotating shaft is provided with a traction rope, the drainage well is provided with a traction wheel, the traction rope passes around the traction wheel and is connected to the float plate, when the first valve plate and the lifting valve are closed, the second valve plate is in the open state.

[0012] By adopting the above technical solution, when the lifting valve plate closes the inlet, rainwater on the ground can flow into the drainage well through the drainage hole, and the water flows into the rainwater collector through the second drainage outlet. When the first valve plate opens, the sliding rod drives the lifting sleeve to rise, and the lifting sleeve drives the sliding rod and float plate to rise. The torsion spring returns from the torsional state to the natural state, and the rotating shaft winds up the traction rope and closes the second valve plate. When the water inflow is too large or the first drainage outlet is blocked, causing water to accumulate in the drainage well, as the water accumulates, the float plate moves upward and drives the traction rope to open the second drainage outlet, thereby realizing the drainage of the second drainage outlet and reducing the water accumulation in the drainage well.

[0013] Optionally, a limit rod is provided on the lifting sleeve, and when the first valve plate is opened to a certain angle, the limit rod abuts against the well cover plate.

[0014] By adopting the above technical solution, the limiting rod restricts the occurrence of dead points between the first valve plate and the slider, thereby avoiding the situation where the lifting valve and the first valve plate cannot be opened normally.

[0015] Optionally, the traction wheel is provided in two parts, and the traction rope passes between the two traction wheels.

[0016] By adopting the above technical solution, the situation of the traction rope derailing from the traction wheel can be avoided.

[0017] Optionally, the rainwater collector is connected to a filter device, and the filter device is connected to a water storage tank.

[0018] By adopting the above technical solution, rainwater flows into a water storage tank after passing through a filtration device. The water storage tank is used to store the filtered rainwater for future use. The rainwater in the water storage tank is then discharged into areas that need drainage, such as drainage ditches or reservoirs, thus realizing the collection, filtration, storage, and utilization of rainwater.

[0019] Optionally, the filtration device includes a filter housing, which is connected to the rainwater collector and the water storage tank. A water pump is installed inside the filter housing. A grid filter plate, a graphene filter layer, and a carbon nanotube layer are sequentially arranged inside the filter housing. The grid filter plate is close to the rainwater collector, and the carbon nanotube layer is close to the water storage tank.

[0020] By employing the above-mentioned technical solutions, the mesh filter plate can capture particles and impurities of different sizes in rainwater. Graphene, a very thin material, can filter out fine impurities and microorganisms. It also possesses high chemical stability and corrosion resistance. The carbon nanotube layer can capture harmful substances in water, such as organic compounds and heavy metals, at the molecular level. The carbon nanotube layer can also promote the evaporation and condensation of water molecules, thereby improving water quality and enhancing the filtration effect on rainwater.

[0021] Optionally, the drainage plate is inclined, with the inclined direction facing the water inlet, and the surface of the manhole cover is recessed towards the water inlet.

[0022] By adopting the above technical solution, rainwater can flow smoothly into the drainage well, reducing the accumulation of rainwater on the road surface.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When rainwater needs to be stored in the planting layer, the lifting valve closes the inlet, thus storing the rainwater in the planting layer. If too much rainwater is stored, the rainwater seeping out of the planting layer can be discharged into the drainage well through the inlet hole of the manhole cover and into the rainwater collector through the second drain outlet. At the same time, the lifting valve can be opened by rotating the screw, and the rainwater flows through the filter hole to the drainage plate and then into the drainage well. When the lifting valve is raised, it drives the first valve plate to open, so that the rainwater is discharged into the rainwater collector through the first drain outlet.

[0025] 2. When there is heavy rainfall or the first drain outlet is blocked, causing water to accumulate in the drainage well, as the liquid level rises, the water drives the float to move upward. The float pulls the traction rope, which in turn pulls the rotating shaft to open the second valve plate. This allows the first and second drain outlets to drain water simultaneously when the drainage well is filled with water. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a multifunctional rainwater storage and drainage garden system.

[0032] like Figure 1 , Figure 2 and Figure 3The multi-functional rainwater storage and drainage garden system includes a rainwater collector 1, a drainage well 2, and a drainage plate 3. The drainage well 2 is located above the rainwater collector. An inlet 21 is provided on the side wall of the drainage well 2, and a first drainage outlet 22 and a second drainage outlet 23 are provided at the bottom of the drainage well 2. The first drainage outlet 22 and the second drainage outlet 23 are connected to the rainwater collector 1. A rotating screw 24 is rotatably connected to the drainage well 2, and a lifting valve 25 is threaded onto the rotating screw 24. The lifting valve 25 closes the inlet 21. A connecting rod 26 is provided on the lifting valve 25, and the end of the connecting rod 26 away from the lifting valve 25 is slidably connected to the drainage well 2. A lifting block 27 is fixedly provided on the connecting rod 26, and a rotating rod 28 is hinged to the bottom of the lifting block 27. A first valve plate 29 is rotatably provided on the side wall of the drainage well 2. The valve plate 29 is hinged to the rotating rod 28. The angle between the surface of the first valve plate 29 and the rotating rod 28 is less than 45 degrees. A lifting sleeve 4 is provided on the connecting rod 26. The opening of the lifting sleeve 4 faces downward. A sliding rod 41 is slidably provided inside the lifting sleeve 4. A float plate 42 is connected to the bottom of the sliding rod 41. A limit rod 43 is provided at the top of the lifting sleeve 4. A rotating shaft 44 is rotatably provided on the side wall of the drainage well 2. A second valve plate 45 for closing the second drain outlet 23 is provided on the rotating shaft 44. A torsion spring 46 is provided on the rotating shaft 44. One end of the torsion spring 46 is connected to the rotating shaft 44, and the other end is connected to the drainage well 2. A traction rope 47 is wound on the rotating shaft 44. Two traction wheels 48 are provided on the drainage well 2. The traction rope 47 passes between the two traction wheels 48 and is connected to the float plate 42. The drainage well 2 is equipped with a well cover plate 5, and the well cover plate 5 has a water inlet hole 51. The surface of the well cover plate 5 is recessed towards the water inlet hole 51.

[0033] The drainage board 3 is installed on the rainwater collector 1. The top surface of the drainage board 3 is inclined towards the water inlet 21 of the drainage well 2. A planting board 6 is installed on the drainage board 3. Several water-permeable holes 61 are opened on the planting board 6. A planting layer 62 is installed on the planting board 6.

[0034] A rainwater collector 1 is connected to a filter device 7. The filter device 7 includes a filter housing 71, which is connected to the rainwater collector 1. A water pump 72 is installed inside the filter housing 71 to pump water out of the rainwater collector 1. A grid filter plate 73, a graphene filter layer 74, and a carbon nanotube layer 75 are arranged sequentially from the direction away from the water pump 72 inside the filter housing 71. A water storage tank 76 is connected to the filter housing 71. The carbon nanotube layer 75 is closer to the water storage tank 76 than the grid filter plate 73.

[0035] During normal use, the lifting valve 25 closes the drain outlet, and the first valve plate 29 is also closed. The float 42 pulls the traction rope 47, which in turn pulls the rotating shaft 44 to open the second valve plate 45. When it rains, rainwater is stored in the planting layer 62. When there is too much rainwater, the excess rainwater will flow into the drainage well 2 through the manhole cover plate 5 and then into the rainwater collector 1 through the second drain outlet 23 for recycling. This allows rainwater to be stored in the soil for plants to absorb, reducing the need to irrigate the plants again when there is less rain. At the same time, if the rainfall is too heavy on a given day, the excess rainwater that overflows from the planting layer 62 can also be discharged into the rainwater collector 1 for collection, achieving a more rational use of rainwater resources.

[0036] When rainfall is frequent and the planting layer 62 cannot be soaked in water for a long time, the rotating screw 24 is rotated. The rotating screw 24 drives the lifting valve 25 to rise, the lifting valve 25 drives the connecting rod 26 to rise, the connecting rod 26 drives the sliding block to rise, and the sliding block causes the rotating rod 28 to rotate the first valve plate 29, thereby opening the first drain outlet 22. Rainwater flows from the planting layer 62 through the water permeable hole 61 to the drainage plate 3, and then through the drainage plate 3 into the drainage well 2, thus maintaining the water content of the planting layer 62 at a normal level during the rainy season.

[0037] When the linkage rod 26 is lifted, it drives the lifting sleeve to lift, and the lifting sleeve drives the float plate 42 to lift. When the limit rod 43 abuts against the well cover plate 5, the lifting valve 25 and the first valve plate 29 can no longer be opened, thus avoiding the dead point between the rotating rod 28 and the first valve plate 29. At the same time, the torsion spring 46 drives the rotating shaft to rotate and rewind, and the second valve plate 45 flips to close the second drain port 23, thus realizing the use of the first drain port 22 for discharge alone, and using the second drain port 23 as a backup drain port.

[0038] When the first drain outlet 22 is blocked or the rainfall is too heavy, causing water to accumulate in the drainage well 2, as the water level in the drainage well 2 increases, the water level gradually rises. The accumulated water causes the float plate 42 to move upward, and the float plate 42 causes the sliding rod 41 to move up and down in the lifting sleeve. At this time, the float plate 42 pulls the traction rope 47, and the traction rope 47 causes the rotating shaft 44 to rotate. The rotating shaft 44 causes the second valve plate 45 to open, thereby realizing that the first drain outlet 22 and the second drain outlet 23 open at the same time, reducing the situation where the drainage well 2 cannot drain normally.

[0039] When the rainwater collector 1 reaches a certain water level, the water pump 72 is activated to pump the water. The rainwater first passes through a mesh filter plate 73, which captures particles and impurities of different sizes in the rainwater. Then it passes through a graphene filter layer 74. Graphene is a very thin material that can filter out fine impurities and microorganisms. It also has high chemical stability and corrosion resistance. Next, it passes through a carbon nanotube layer 75, which can capture harmful substances in the water at the molecular level, such as organic compounds and heavy metals. The carbon nanotube layer 75 also promotes the evaporation and condensation of water molecules, thereby improving water quality and enhancing the filtration effect on rainwater. Finally, the rainwater is collected in a water storage tank 76, which stores the filtered rainwater for future use. The rainwater in the water storage tank 76 is then discharged into areas requiring drainage, such as drainage ditches or reservoirs, thus realizing the collection, filtration, storage, and utilization of rainwater.

[0040] The implementation principle of this application embodiment is as follows: When it is necessary to store rainwater in the planting layer 62, the lifting valve 25 closes the water inlet 21, so that the rainwater can be stored in the planting layer 62. If too much rainwater is stored, the rainwater that seeps out of the planting layer 62 can be discharged into the drainage well 2 through the water inlet 51 of the well cover plate 5 and into the rainwater collector 1 through the second drain outlet 23. At the same time, the lifting valve 25 can be opened by rotating the rotating screw 24, and the rainwater flows through the filter hole to the drainage plate 3 and then into the drainage well 2. At the same time, when the lifting valve 25 is lifted, it drives the first valve plate 29 to open, so that the rainwater is discharged into the rainwater collector 1 through the first drain outlet 22.

[0041] When there is heavy rainfall or the first drain outlet 22 is blocked, causing water to accumulate in the drainage well 2, as the liquid level rises, the water drives the float 42 to move upward. The float 42 pulls the traction rope 47, and the traction rope 47 pulls the rotating shaft 44 to rotate, causing the second valve plate 45 to open. Thus, when the drainage well 2 is filled with water, the first drain outlet 22 and the second drain outlet 23 can drain water simultaneously.

[0042] 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.
