Description

Technical Field

[0001] This application relates to the field of sponge city technology for landscape architecture, and in particular to a three-dimensional layered rain garden lawn structure. Background Technology

[0002] Rain gardens, as a key facility in the construction of sponge cities, retain, infiltrate, and purify rainwater through vegetation, soil, and microbial systems, reducing surface runoff and providing water sources for greening, thus possessing both ecological and water-saving value. Current rain gardens suffer from two main problems: First, they generally use a single-layer water storage box structure, relying solely on a single bottom water storage layer to temporarily store rainwater. This limits the water storage capacity and lacks a tiered water storage and utilization design, making them prone to overflow during heavy rainfall and resulting in wasted rainwater resources. Second, while existing systems can reduce water consumption for greening through rainwater utilization, they lack soil moisture sensing and linkage control mechanisms. They cannot automatically adjust the irrigation speed based on the actual soil moisture, requiring manual intervention and exhibiting low levels of intelligence. This can lead to either insufficient irrigation affecting vegetation growth or excessive irrigation causing redundant water consumption, making it difficult to meet the needs for efficient and intelligent rainwater utilization and greening maintenance. Utility Model Content

[0003] In view of the above-mentioned problems existing in the prior art, the main objective of this application is to provide a three-dimensional layered rain garden lawn structure.

[0004] The technical solution of this application is as follows: a three-dimensional layered rain garden lawn structure, including a primary garden component and a secondary garden component installed at the roof drainage outlet. The primary garden component is used to collect rainwater and provide rainwater to the secondary garden component. The secondary garden component is used to classify and utilize the rainwater. The primary garden component is set on top of the secondary garden component. An adjustment component for controlling the rainwater irrigation speed is provided at the connection between the primary garden component and the secondary garden component.

[0005] In a preferred embodiment, the primary garden component includes a planting box shell a fixedly connected to the roof drain outlet. Two reinforcing ribs a are fixedly connected to both sides of the inner wall of the planting box shell a. A bracket a is installed between the tops of the two reinforcing ribs a. A perforated copper plate a is installed between the tops of the two brackets a. A soil-proof non-woven fabric a is laid on top of the perforated copper plate a. A planting area a is provided above the soil-proof non-woven fabric a. A drain valve a is fixedly installed at the bottom of the planting box shell a. The planting box shell a is divided into cavities a by the perforated copper plate a.

[0006] By adopting the above technical solution, a double-layer water storage system can be constructed through the layered arrangement of primary and secondary garden components. The outer shell of the planting box (a) is divided into cavities (a) by perforated copper plates (a), which can temporarily store rainwater collected from the roof drain. Similarly, the outer shell of the planting box (b) forms cavities (b) to receive rainwater transported by the primary garden components. The double-layer cavities significantly increase the total water storage capacity and avoid overflow waste caused by large rainfall in a single water storage layer.

[0007] In a preferred embodiment, the adjustment assembly includes a drain pipe fixedly connected inside the outer shell a of the planting box, a drip irrigation port fixedly connected to one side of the drain pipe, and a solenoid valve fixedly installed on the outer periphery of the drain pipe and above the drip irrigation port.

[0008] By adopting the above technical solution, the opening and closing of the channel inside the drainage pipe can be controlled by setting the solenoid valve, thereby adjusting the irrigation speed of the drip irrigation outlet.

[0009] In a preferred embodiment, the regulating assembly further includes a soil moisture sensor disposed inside the secondary garden assembly, and a controller is fixedly mounted on the outside of the planting box housing a.

[0010] By adopting the above technical solution and setting up a soil moisture sensor, the soil moisture data of planting area b can be monitored in real time and transmitted to the controller.

[0011] In a preferred embodiment, the secondary garden component includes a planting box shell b fixedly connected to the bottom of the planting box shell a. Supports b are fixedly installed on both sides of the inner wall of the planting box shell b. A perforated copper plate b is installed at the top of the support b. A soil-resistant non-woven fabric b is laid on top of the perforated copper plate b. A planting area b is laid above the soil-resistant non-woven fabric b. Four reinforcing ribs b are fixedly connected to the inner wall of the planting box shell b, and each reinforcing rib b is connected to a support b. The planting box shell b is divided into cavities b by the perforated copper plates b. A relief valve b is fixedly installed at the bottom of the planting box shell b.

[0012] By adopting the above technical solutions and using the combination of reinforcing ribs and supports, the load-bearing capacity of the planting box shell and perforated copper plate can be greatly enhanced, effectively distributing the weight of soil, vegetation and rainwater in the planting area, and preventing the structure from deforming or being damaged due to uneven stress.

[0013] In a preferred embodiment, the end of the drip irrigation inlet away from the drainage pipe extends into the interior of the planting area b, and the soil moisture sensor is buried inside the planting area b.

[0014] By adopting the above technical solution, the soil moisture sensor can be buried in planting area b.

[0015] In a preferred embodiment, a connecting pipe is fixedly connected to the bottom of the planting box shell a, and the top end of the connecting pipe extends into the interior of the planting box shell a. Both the planting box shell a and the planting box shell b are hinged with sealed access doors. A rainwater collection pool is provided on the outside of the primary garden component, and the end of the connecting pipe away from the planting box shell a extends into the rainwater collection pool.

[0016] By adopting the above technical solution, excess rainwater can be discharged into a rainwater collection tank through a connecting pipe for storage, further expanding the rainwater storage space and reducing rainwater waste.

[0017] Compared with the prior art, the advantages and positive effects of this application are as follows: 1. In this application, a two-layer water storage system can be constructed by layering primary and secondary garden components. The outer shell of the planting box a is divided into cavities a by perforated copper plates a, which can temporarily store rainwater collected from the roof drain. Similarly, the outer shell b of the planting box forms a cavity b, which receives rainwater transported by the primary garden components. The double-layer cavity significantly increases the total water storage capacity and avoids overflow waste caused by large rainfall in a single water storage layer. At the same time, the primary garden components supply water to the secondary garden components, forming a graded process of "collection-transportation-reuse", which allows rainwater resources to be developed in stages and improves utilization rate, in line with the needs of sponge city water resource recycling.

[0018] 2. In this application, by setting a soil moisture sensor, the soil moisture data of planting area b can be monitored in real time and transmitted to the controller. The controller automatically controls the opening and closing of the solenoid valve on the drainage pipe according to the preset humidity threshold, thereby adjusting the irrigation speed of the drip irrigation port. This design does not require manual operation and realizes the intelligent and automated irrigation process. Attached Figure Description

[0022] Reference Figure 1-5 A three-dimensional layered rain garden lawn structure includes a primary garden component 1 and a secondary garden component 2 installed at the roof drain outlet. The primary garden component 1 is used to collect rainwater and supply rainwater to the secondary garden component 2. The secondary garden component 2 is used for graded utilization of rainwater. The primary garden component 1 is set on top of the secondary garden component 2. An adjustment component 3 for controlling the rainwater irrigation speed is provided at the connection between the primary garden component 1 and the secondary garden component 2.

[0023] Specifically, the primary garden component 1 includes a planting box shell a101 fixedly connected to the roof drain outlet. Two reinforcing ribs a102 are fixedly connected to both sides of the inner wall of the planting box shell a101. A bracket a103 is installed between the tops of the two reinforcing ribs a102, and a perforated copper plate a104 is installed between the tops of the two brackets a103. A soil-resistant non-woven fabric a105 is laid on top of the perforated copper plate a104. Through the layered arrangement of the primary garden component 1 and the secondary garden component 2, a double-layer water storage system can be constructed. The planting box shell a101, separated by the perforated copper plate a104, forms a cavity a, which can temporarily store rainwater collected from the roof drain outlet. Similarly, the planting box shell b201 forms a cavity b, which receives rainwater transported by the primary garden component 1. The double-layer cavity significantly increases the total water storage capacity, avoiding overflow waste caused by large rainfall in a single water storage layer. A planting area a106 is located above the soil-resistant non-woven fabric a105. A relief valve a107 is fixedly installed at the bottom of planting box a101. The outer shell a101 of planting box is divided into a cavity a by a perforated copper plate a104. The adjustment component 3 includes a drain pipe 301 fixedly connected inside the outer shell a101 of planting box. A drip irrigation port 302 is fixedly connected to one side of the drain pipe 301. A solenoid valve 303 is fixedly installed on the outer periphery of the drain pipe 301 and above the drip irrigation port 302. The adjustment component 3 also includes a soil moisture sensor 305 set inside the secondary garden component 2. Through the setting of the soil moisture sensor 305, the soil moisture data of planting area b206 can be monitored in real time and transmitted to the controller 304. The controller 304 automatically controls the opening and closing of the solenoid valve 303 on the drain pipe 301 according to the preset humidity threshold, thereby adjusting the irrigation speed of the drip irrigation port 302. This design does not require manual operation and realizes the intelligent and automated irrigation process. The controller 304 is fixedly installed on the outer side of the outer shell a101 of planting box.

[0024] Specifically, the secondary garden component 2 includes a planting box shell b201 fixedly connected to the bottom of the planting box shell a101. Supports b203 are fixedly installed on both sides of the inner wall of the planting box shell b201. A perforated copper plate b204 is installed at the top of the support b203. A soil-resistant non-woven fabric b205 is laid on top of the perforated copper plate b204. A planting area b206 is laid on top of the soil-resistant non-woven fabric b205. Four reinforcing ribs b202 are fixedly connected to the inner wall of the planting box shell b201. Through the combined use of the reinforcing ribs and the supports, the load-bearing capacity of the planting box shell and the perforated copper plate can be significantly enhanced, effectively distributing the weight of the soil, vegetation, and rainwater in the planting area, preventing deformation and damage to the structure due to uneven stress, improving overall stability, and extending service life. The reinforcing ribs b202 are all connected to the supports b203. The planting box shell b201 is perforated... A copper plate b204 divides the space to form a cavity b. A control valve b207 is fixedly installed at the bottom of the planting box shell b201. The end of the drip irrigation port 302 away from the drainage pipe 301 extends into the interior of the planting area b206. The soil moisture sensor 305 is buried inside the planting area b206. A connecting pipe 4 is fixedly connected to the bottom of the planting box shell a101. The top end of the connecting pipe 4 extends into the interior of the planting box shell a101. Both the planting box shell a101 and the planting box shell b201 are hinged with sealed maintenance doors 5. The control valves a107 and b207 can be used for periodic emptying and cleaning. The sealed maintenance doors 5 allow staff to clean the inside of the box. The operation is convenient and efficient. A rainwater collection pool is provided on the outside of the primary garden component 1. The end of the connecting pipe 4 away from the planting box shell a101 extends into the rainwater collection pool.

[0025] Working principle: First, a double-layer water storage system can be constructed through the layered arrangement of primary garden component 1 and secondary garden component 2. The outer shell of the planting box a101 is divided by a perforated copper plate a104 to form cavity a, which temporarily stores rainwater collected from the roof drain. Similarly, the outer shell b201 of the planting box forms cavity b, which receives rainwater from primary garden component 1. When cavity a of primary garden component 1 overflows, excess rainwater can be discharged into a rainwater collection tank through connecting pipe 4, further expanding the rainwater storage space and reducing rainwater waste. The soil moisture sensor 305 monitors the planting area b2 in real time. The soil moisture data of 06 is transmitted to the controller 304, which automatically controls the opening and closing of the solenoid valve 303 on the drainage pipe 301 according to the preset humidity threshold, thereby adjusting the irrigation speed of the drip irrigation port 302. When the soil moisture is lower than the threshold, the solenoid valve 303 opens and the drip irrigation port 302 replenishes water to the planting area b206. When the humidity reaches the standard, the solenoid valve 303 closes and irrigation stops. This design does not require manual operation, realizes the intelligent and automated irrigation process, avoids the impact of insufficient irrigation on vegetation growth, and prevents excessive irrigation from causing redundant water consumption, thus taking into account both ecological maintenance and water-saving benefits.
