Description

Technical Field

[0001] The utility model relates to the technical field of biological retention facilities, in particular to a self-cleaning, self-controllable and storable modular biological retention system. Background Art

[0002] The self-purifying, self-controllable and storable modular bioretention system is an innovative rainwater treatment facility. It purifies rainwater through bioretention technology and combines self-control and storage functions to achieve efficient rainwater treatment and utilization. The system consists of multiple independent modules, each of which has purification, control and storage capabilities and can be flexibly combined and expanded according to needs. This system can not only effectively remove pollutants in rainwater, but also monitor and adjust treatment parameters in real time to ensure stable and reliable treatment effects. Its modular design improves the utilization rate of water resources and reduces the pressure on urban drainage systems. It has broad application prospects and is of great significance to improving urban water environment and promoting ecological civilization construction.

[0003] As one of the core technologies for the construction of "sponge cities", bioretention facilities play an important role in solving urban hydrological and water quality problems. They also have superior landscape effects and flexible layout characteristics. However, this type of facility also has certain limitations when used. Specifically, its rainwater penetration capacity is not strong and is usually only suitable for treating conventional rainfall. When faced with high-intensity rainfall, the rainwater penetration rate often cannot keep up with the rainfall, which not only weakens the purification effect of rainwater, but may also cause overflow, thereby affecting the environmental adaptability of the retention system. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a self-cleaning, self-controllable and storable modular biological retention system to solve the technical problem that when encountering high-intensity rainfall, rainwater does not have time to penetrate, not only can the rainwater not be purified, but it causes overflow, thereby reducing the environmental applicability of the retention system.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a self-cleaning, self-controllable and storable modular biological retention system, comprising a planting module, a filtering module and a water storage module, wherein an infiltration and drainage regulating mechanism is arranged inside the planting module, and the infiltration and drainage regulating mechanism comprises a micro-moisture tube, a quick-drain pipe is arranged on the outside of the micro-moisture tube, a micro-infiltration layer is arranged between the micro-moisture tube and the quick-drain pipe, and the inside of the micro-moisture tube is filled with absorbent cotton. There are multiple infiltration and drainage regulating mechanisms, which are arranged in an equidistant array, an overflow rainwater well is arranged on one side of the planting module, and the filtering module is connected to the overflow rainwater well through an overflow pipe.

[0006] By adopting the above technical solution, the infiltration and drainage regulating mechanism mainly infiltrates rainwater through the semicircular micro-seepage layer during light rain, ensuring that water is slowly and evenly supplied to the soil layer, avoiding excessive infiltration, which is beneficial to the continuous moisture retention of the soil and provides a stable growth environment for plants.

[0007] Furthermore, the inner wall of the micro-moisture tube is rough, the outer surface of the quick-drain tube is smooth, the interior is porous, and the whole is a water-tight semicircular ring structure. The outer surface and interior of the micro-permeable layer are made of micro-permeable material and are in a semicircular ring structure.

[0008] By adopting the above technical solution, the rough design of the inner wall of the micro-moisture tube is conducive to better adhesion of water to the tube wall, and is slowly and continuously released into the soil layer through the filled micro-moisture absorbent cotton, providing a stable water supply for plants. This structure ensures the uniformity and durability of soil moisture.

[0009] Furthermore, the planting module is composed of a plant planting layer, a permeable geotextile, a filterable sand layer and a concave-convex drainage layer, in order from top to bottom.

[0010] By adopting the above technical solution, the plant planting layer of the planting module provides the soil environment required for the growth of green plants, which is helpful for the rooting and growth of plants. At the same time, the plants absorb nutrients in the soil for photosynthesis, thereby achieving the effect of purifying the air.

[0011] Furthermore, the filtration module is composed of multiple modules, and the fillers in each module are 9.5 cm gravel layer, 1 cm thick partition, 9 cm ceramsite layer, 1 cm thick partition, 9 cm volcanic rock layer, 1 cm thick partition, 9.5 cm glass light stone layer, and partitions are arranged between each module.

[0012] By adopting the above technical solution, this modular design makes installation, disassembly and maintenance more convenient. At the same time, the partition setting between the modules ensures the independence of each filter layer, prevents the mixing of different filter materials, and ensures the filtering effect.

[0013] Furthermore, the water storage module is composed of multiple modules, and the height of each module is 600 mm. The bottom of the water storage module is paved with soil and breathable and anti-seepage sand.

[0014] By adopting the above technical solution, this modular structure makes the entire water storage system more flexible and scalable, and it is easy to increase, decrease and adjust according to actual needs. The height of each module is 600mm. This standardized size facilitates production, transportation and installation, and improves construction efficiency.

[0015] Furthermore, a soil moisture probe is disposed inside the planting module, and an ultraviolet disinfection module, an aeration module and a liquid pump are disposed on one side of the water storage module.

[0016] By adopting the above technical solution, the soil moisture probe can monitor soil moisture in real time and provide the system with accurate humidity data, which helps the centralized control system to intelligently adjust irrigation according to soil moisture conditions, ensuring that plants get the right amount of water, so that they will not wither due to lack of water, nor be affected in growth due to excessive water.

[0017] Furthermore, the soil moisture probe, ultraviolet disinfection module, aeration module and liquid pump are all electrically connected to the solar panel power supply through a centralized control system.

[0018] By adopting the above technical solutions, the entire system can operate automatically and intelligently. The soil moisture probe monitors soil moisture in real time and transmits data to the centralized control system. The system automatically adjusts irrigation according to the data, realizing precise management of urban greening.

[0019] Furthermore, partition support blocks are provided at the corners of the partitions, and adjacent filter modules are detachably connected via buckles.

[0020] By adopting the above technical solution, the partition support block increases the stability of the partition and prevents its deformation or displacement, thereby ensuring the structural stability of the filter module. This design enables the filter module to maintain its shape and position unchanged during use, thereby improving the reliability and durability of the entire filtration system.

[0021] Furthermore, an outer plate is provided on the outer side of the planting module, and a plurality of openings are provided on the surface of the outer plate and are arranged in an equidistant array.

[0022] By adopting the above technical solution, the outer panel arranged on the outside of the planting module provides protection for the entire module, increases the stability and durability of the structure, and the outer panel can resist the direct impact of the external environment on the planting module and reduce the risk of damage.

[0023] Furthermore, a cavity is opened inside the outer plate, and the interior of the cavity is filled with breathable and anti-seepage sand.

[0024] By adopting the above technical solution, the cavity provides a space for breathable anti-seepage sand, which is conducive to maintaining soil permeability and preventing soil compaction. At the same time, the anti-seepage sand can also effectively prevent water from infiltrating and losing too quickly, maintain moderate soil moisture, and provide good growth conditions for plants.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] The utility model uses the infiltration and drainage regulating mechanism, and after the rainwater falls on the plant planting soil layer, it will undergo a fine filtering and infiltration process. First, the rainwater passes through the soil layer, through the permeable geotextile, the filter sand layer, and then through another layer of permeable geotextile to reach the concave and convex infiltration and drainage layer. Here, the infiltration and drainage regulating mechanism plays a key role. In light rain, the semicircular micro-infiltration layer is the main infiltration path, which allows rainwater to slowly and evenly infiltrate into the next structural layer, ensuring that the soil is replenished with an appropriate amount of water while avoiding excessive infiltration. When moderate or heavy rain comes, the semicircular quick-drain pipe becomes dominant, which can quickly drain the rainwater from the upper structure to the lower structure layer, preventing damage to the soil and plants due to rainwater accumulation. In addition, the infiltration and drainage regulating mechanism is also equipped with a micro-moisture pipe with a rough inner wall and micro-moisture absorbent cotton filled in the pipe, which cleverly absorbs the clean rainwater from the bottom structural layer into the soil layer through the absorbent cotton, providing continuous and stable moisture supply for the soil.

The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0038] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1:

[0039] A self-cleaning, self-controllable and storable modular bioretention system, such as Figure 1-Figure 9 As shown, it includes a planting module 1, a filtering module 2 and a water storage module 3. The planting module 1 is provided with an infiltration and drainage regulating mechanism 8 inside. The infiltration and drainage regulating mechanism 8 includes a micro-moisture tube 801. A quick-drain pipe 802 is provided outside the micro-moisture tube 801. A micro-infiltration layer 803 is provided between the micro-moisture tube 801 and the quick-drain pipe 802. The inside of the micro-moisture tube 801 is filled with absorbent cotton 804. There are multiple infiltration and drainage regulating mechanisms 8, which are arranged in an equidistant array. An overflow rainwater well 5 is provided on one side of the planting module 1. The filtering module 2 is connected to the overflow rainwater well 5 through an overflow pipe 6. The infiltration and drainage regulating mechanism 8 is mainly used in light rain. Rainwater must infiltrate through the semicircular micro-infiltration layer 803 to ensure that water is slowly and evenly supplied to the soil layer to avoid excessive infiltration, which is beneficial to the continuous moisture retention of the soil and provides a stable growth environment for plants. At the same time, during moderate to heavy rain, the semicircular quick-drain pipe 802 can quickly drain rainwater from the upper structure to the lower structure layer to prevent water accumulation. In addition, the micro-moisture pipe 801 uses the filled micro-moisture absorbent cotton 804 to absorb the clean rainwater from the bottom structure layer into the soil layer, thereby achieving effective soil replenishment. These characteristics jointly improve the environmental applicability of the system device, enabling it to flexibly respond to rainfall of different intensities.

[0040] See also Figure 4 , Figure 5The inner wall of the micro-moisture tube 801 is rough, the outer surface of the quick-drain tube 802 is smooth, the interior is porous, and the overall structure is a watertight semicircular ring structure.

This structure ensures the uniformity and durability of soil moisture. At the same time, the outer surface of the quick-drain tube 802 is smooth, which helps rainwater to flow through quickly; its internal porous structure can enhance the efficiency of drainage. The quick-drain tube 802 is an impermeable semi-circular ring structure as a whole, which can quickly drain rainwater from the upper structure to the lower structure layer during moderate and heavy rains, preventing excessive soil infiltration and water accumulation. The micro-seepage layer 803 is made of micro-seepage material, which ensures that rainwater can slowly penetrate into the next structural layer, further regulating and controlling soil moisture, and providing optimal conditions for plant growth.

At the same time, plants absorb nutrients in the soil for photosynthesis to achieve the effect of purifying the air. At the same time, the permeable geotextile has good water permeability, which can effectively prevent soil loss and maintain soil stability. The filter sand layer can further filter larger impurity particles in rainwater to ensure that the rainwater entering the next layer is clearer. The concave-convex infiltration and drainage layer uses its special structure to achieve rapid infiltration and discharge of rainwater to prevent the occurrence of water accumulation.

The 9.5 cm gravel layer can effectively remove large particles of impurities, the 9 cm ceramsite layer and the 9 cm volcanic rock layer can adsorb and remove smaller pollutants, and the 9.5 cm glass light stone layer further ensures clear water quality. This progressive layer-by-layer filtering method greatly improves the purification effect of rainwater and provides a strong guarantee for the water quality safety downstream. Embodiment 4:

[0049] The implementation principle of the utility model is as follows: the system consists of four main parts, namely, solar panels 16 and a centralized control system 15, an integrated infiltration and drainage and adaptive adjustment planting module 1, a detachable multi-media filtration module 2, and an automatic purification and disinfection water storage module 3;

[0050] Solar panels 16 and centralized control system 15: The solar panels 16 are mainly used to convert into electrical energy to provide electrical energy to the centralized control system. The centralized control system 15 is mainly used to control the opening of the automatic irrigation system according to the integrated infiltration and drainage and adaptive adjustment of the soil humidity in the planting module 1. The liquid level meter in the water storage module 3 is not shown in the figure to control whether to open the ultraviolet disinfection module 13 and the aeration module 14;

[0051] Infiltration and drainage integration and adaptive adjustment planting module 1: mainly plants, planting soil layer, soil moisture probe 4, gravel layer, concave-convex drainage board, micro-moisture infiltration and drainage adjustment pipe, among which, semi-circular ring fast drainage pipe 802, when it rains heavily, the rainfall is discharged into the next layer through the semi-circular ring fast drainage pipe 802, and the excess water in the process of light rain and soil irrigation slowly enters the next layer through the semi-circular ring micro-infiltration layer 803;

[0052] Rainwater falls to the plant planting soil layer, and then passes through the soil layer through the permeable geotextile, the filter sand layer, and the permeable geotextile to the concave-convex infiltration and drainage layer, and the infiltration and drainage adjustment mechanism 8. During light rain, rainwater mainly infiltrates through the semicircular micro-infiltration layer 803 and infiltrates to the next structural layer. During medium and heavy rain, rainwater is quickly discharged from the upper structure to the lower structure layer through the semicircular quick-drain pipe 802. The micro-moisture pipe 801 has a rough inner wall and is filled with micro-moisture absorbent cotton 804. The clean rainwater from the bottom structural layer is absorbed by the absorbent cotton to the soil layer for water replenishment.

The fillers in each module are 9.5 cm gravel layer, 1 cm thick partition, 9 cm ceramsite layer, 1 cm thick partition, 9 cm volcanic rock layer, 1 cm thick partition, 9.5 cm glass light stone layer. There is a partition 12 in the middle of each layer of media. The partition 12 is hollow and its main function is to reduce pollutants in rainwater through layer-by-layer filtration.

[0054] The water storage module 3 is mainly composed of multiple modules, each of which is 600mm high. After the soil is compacted at the bottom, a layer of 20cm thick breathable and anti-seepage sand is laid, and the water storage module 3 is placed above the permeable and anti-seepage sand. In the automatic purification and disinfection water storage module layer, a liquid pump 17 is required at a suitable position to pump the rainwater through the rotating nozzle. Among them, this layer needs to be equipped with an ultraviolet disinfection module 13 and an aeration module 14. The power supply used comes from the solar panel 16 on the ground, which converts light energy into electrical energy to power various electrical equipment and centralized control systems. Excess rainwater is collected and overflowed through the overflow pipe 6 in this layer to the middle overflow rainwater well 5 and discharged to the rainwater pipe network;

[0055] The humidity of the soil moisture probe 4 in the planting module 1 is controlled to be integrated and adaptively adjusted. When the humidity in the soil does not meet the requirements, the centralized control system 15 controls the ultraviolet disinfection module 13 and the aeration module 14 in the water storage module 3 to operate. After the operation is completed, the liquid pump 17 is started to pump water and automatically rotate the sprinkler head to work.
