Description

Technical Field

[0001] The present invention belongs to the technical field of sponge cities, and in particular relates to a modular intelligent blue-green roof device. Background Art

[0002] As one of the important measures for sponge city construction, green roofs can improve urban thermal environment, regulate rainwater runoff, enhance urban landscape, extend roof life, reduce noise pollution, and improve air quality without occupying additional land. They have broad application prospects.

[0003] Generally speaking, green roofs generally include vegetation layer, soil matrix layer, filtration layer, drainage layer and root barrier waterproof layer from top to bottom. At present, most green roofs are built according to this structure. However, the existing green roof system faces the problem of limited rainwater retention capacity and difficult recovery during the rainy season. Due to the lack of effective water storage and drainage mechanisms, it is difficult for green roofs to adjust their rainwater retention capacity during continuous rainfall events, resulting in the inability to effectively reduce the direct runoff during continuous rainfall, which increases the pressure on the urban drainage system. After the rainy season, due to the long dry period, high wind speed on the roof, and poor water retention capacity of the matrix, the plants on the green roof may die prematurely due to lack of water due to rapid evaporation of water, and artificial irrigation is often costly. Traditional irrigation methods are often inefficient, not only wasting water resources due to direct surface evaporation, but also failing to effectively guarantee the water needs of plants during droughts. The premature death of vegetation not only affects the ecological benefits of green roofs, but also reduces the durability of their aesthetic value. In addition, traditional roof greening is directly constructed on the roof, which is not only difficult but also accompanied by certain safety risks.

[0004] In summary, existing green roof technologies have deficiencies in rainwater retention and plant maintenance, and lack effective water storage and drainage mechanisms. In addition, traditional irrigation is costly, affects plant growth, reduces ecological benefits and aesthetics, and is difficult to construct and poses safety risks. These problems need to be addressed urgently. Summary of the invention

[0005] The purpose of the present invention is to provide a modular intelligent blue-green roof device to solve the following problems: ① the problem of limited rainwater retention capacity of existing green roofs during continuous rainfall; ② the problem of low water resource utilization efficiency of traditional irrigation methods; ③ the problem of difficulty in construction and high safety risks of traditional roof greening.

[0006] To achieve the above-mentioned purpose, the present invention provides the following solution: The present invention provides a modular intelligent blue-green roof device, comprising a plurality of ecological modules connected in sequence, wherein the ecological module comprises a green roof module and a blue roof module arranged at the bottom of the green roof module, and two adjacent blue roof modules are connected to each other, and the green roof module is provided with a filter layer, a soil matrix layer and a vegetation layer in sequence from bottom to top, and a water storage layer is provided in the blue roof module, and multiple sides of the blue roof module are respectively provided with threaded interfaces A and threaded interfaces B, and the side of the blue roof module located at one end of the ecological module is connected with a balancer through the threaded interface A and the threaded interface B.

[0008] Preferably, a temperature and humidity sensor is provided on one side of the green roof module.

[0009] Preferably, the balancer module is equipped with a water level meter to record the water volume in the aquifer.

[0010] A modular smart blue-green roof drainage method comprises the following steps:

[0012] S2, automatic drainage control: the system automatically opens the drainage pipes based on sensor data and weather forecasts to drain the accumulated water in the aquifer;

[0013] S3, Close during rainfall intervals: During rainfall intervals, close threaded interface A to reduce water loss due to evaporation;

[0014] S4. Timely drainage of accumulated water: Threaded interface B is permanently connected to the drainage pipe to drain the accumulated water in the blue roof module part in time.

[0020] Preferably, the conditions for opening the drainage pipe are when the forecast rainfall exceeds the capacity of the blue roof module or when the air humidity is above 80% and the aquifer is not empty.

[0021] Preferably, the condition for opening the water inlet pipe is that the soil moisture sensor monitors that the moisture content of the substrate of the green roof module is lower than 10% or the air humidity of the surrounding environment is lower than 30% using an air humidity sensor.

[0022] The present invention discloses the following technical effects: the runoff regulation effect of the green roof is enhanced by the aquifer and moisture is provided for vegetation growth; the rainwater retention space of the green roof can be effectively adjusted during continuous heavy rains to improve its ability to absorb and release rainwater, delay the peak time, and reduce the peak flow; during the interval between heavy rains, the rainwater retention space is quickly adjusted through intelligent drainage methods to reduce the directly generated runoff, thereby alleviating the pressure on the urban drainage system.

[0059] 2) Monitor the ambient air humidity through the temperature and humidity sensor, and trigger the water replenishment signal when the air humidity is lower than 30%;

[0060] 3) Monitor the water level of the aquifer through a liquid level sensor and set the normal operating water level range to 40%-80% of the aquifer height.

[0061] (2) Water replenishment control process:

[0062] 1) After receiving the water replenishment signal, the central controller first checks the current water level of the aquifer;

[0063] 2) If the water level is lower than the set value (40% of the height of the aquifer), the following steps are performed: ① The controller sends a signal to open the solenoid valve of the water inlet pipe; ② The water level change is monitored in real time through the balancer; ③ The water replenishment rate is controlled at 2-5L / min to avoid excessive water pressure;

[0064] 3) When the water level reaches the maximum set value (80% of the height of the aquifer): ① the controller automatically closes the solenoid valve of the water inlet pipe; ② the system records the amount and time of water replenishment.

[0065] 4) If the water level does not reach the set value within 15 minutes: ① The system performs fault detection; ② Issues an alarm signal; ③ Continues the water replenishment procedure until the set water level is reached.

[0066] (3) Safety protection mechanism: ① Set the upper limit of water replenishment time to 30 minutes; ② Add an overflow protection device to prevent excessive water replenishment; ③ Automatically cut off the water supply when a system abnormality is detected.

[0074] (2) Drainage control process:

[0075] 1) The drainage procedure is initiated when any of the following conditions are met: ① The weather forecast shows that the rainfall in the next 24 hours will exceed the remaining capacity of the aquifer; ② The ambient air humidity exceeds 80% and the aquifer water level is higher than the minimum set value.

[0076] 2) Drainage program execution steps: ① The controller sends a signal to open the drainage pipe solenoid valve; ② Monitor the drainage process through the balancer; ③ Control the drainage rate within the range of 3-6L / min.

[0077] 3) When the water level drops to the target water level (30% of the aquifer height): ① automatically close the drainage pipe solenoid valve; ② record the drainage volume and drainage time.

[0078] 4) If the water level does not drop to the target value within 20 minutes: ① The system performs pipe blockage detection; ② Issues an alarm signal; ③ Continues the drainage procedure.

[0079] (3) Emergency control mechanism:

[0080] 1) Set up an emergency drainage mode to completely drain the aquifer when heavy rain is forecast;

[0081] 2) Equipped with backup drainage channels to prevent blockage of the main drainage pipe;

[0086] 3) Optimize control parameters based on historical data.

[0087] When the air humidity is higher than 80% or the rainfall in the weather forecast exceeds the capacity of the blue roof module 2, and the aquifer is not empty, the central controller opens the water outlet pipe to discharge the water in the aquifer. After the water level in the aquifer reaches the set water level value, the water outlet pipe is closed. If the water level in the aquifer reaches the set water level value, the water in the aquifer continues to be discharged.
