Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rainwater storage technology, specifically to a circulating aeration biological retention facility. Background Technology
[0002] Rainwater is relatively clean, containing fewer impurities, silt, and other pollutants. It can be diverted and simply filtered before being stored in a water storage system for purposes such as flushing toilets, irrigating greenery, and replenishing landscape ponds.
[0003] In existing bioretention facilities, as rainwater is stored, the soil gradually changes from a loose state to a compact state as water enters the facility. This not only affects the entry of water from subsequent soil layers into the bioretention facility, but the compacted soil can also enter the inlet, causing blockage and affecting the service life of the bioretention facility. In addition, existing bioretention facilities cannot achieve quantitative drainage.
[0004] Therefore, there is an urgent need to provide a solution to address the defects and shortcomings of the existing technologies. Summary of the Invention
[0005] In order to overcome the defects and shortcomings of the existing technology, this utility model provides a circulating aeration biological retention facility.
[0006] The specific solution provided by this utility model is as follows:
[0007] A circulating aeration bioretention facility is characterized by comprising an infiltration-enhancing and drainage module disposed within the soil layer, wherein the infiltration-enhancing and drainage module has a hollow water storage cavity inside, and an air inlet and a water inlet are respectively opened on the top of the infiltration-enhancing and drainage module, a drainage pipe is connected to one side of the infiltration-enhancing and drainage module, a valve is disposed between the infiltration-enhancing and drainage module and the drainage pipe, and a switch is disposed inside the infiltration-enhancing and drainage module, wherein the switch is signal-connected to the valve to control the opening and closing of the valve.
[0008] As a further preferred embodiment of this utility model, the permeation enhancement and drainage module is composed of several permeation enhancement and drainage units spliced together.
[0009] As a further preferred embodiment of this utility model, the permeation-enhancing and drainage unit can be configured with different shapes according to the actual application scenario.
[0010] As a further preferred embodiment of this utility model, the outer edge of the permeation-enhancing and drainage unit is provided with a corresponding splicing part.
[0011] As a further preferred embodiment of the present invention, the water inlet includes a first water inlet and a plurality of second water inlets.
[0012] As a further preferred embodiment of the present invention, the first water inlet is located at the air vent position, and the second water inlet is evenly distributed around the outer periphery of the first water inlet.
[0013] As a further preferred embodiment of this utility model, the vent is positioned higher than the water inlet.
[0014] As a further preferred embodiment of this utility model, the valve is selected as a rotary valve or a telescopic valve.
[0015] As a further preferred embodiment of this utility model, the switch is selected as a liquid level switch.
[0016] As a further preferred embodiment of this utility model,
[0017] When the water level in the storage chamber inside the infiltration and drainage module reaches the preset level, the level switch is triggered to control the valve to open, and the rainwater inside the infiltration and drainage module is discharged from the drainage pipe.
[0018] When the water level in the internal storage chamber of the infiltration and drainage module falls below the preset level, the level switch is triggered to control the valve to close and start the next cycle of aeration.
[0019] Compared with existing technologies, the technical effects that this utility model can achieve include:
[0020] 1) This utility model provides a circulating aeration bioretention facility. After rainwater enters the infiltration and drainage module, the original air inside the infiltration and drainage module is squeezed out from the vent under pressure, which aerates the soil layer, thereby increasing the looseness of the soil layer and preventing the dense soil layer from slowing down or blocking the water inlet process, thus extending the service life of the bioretention facility.
[0021] 2) This utility model provides a circulating aeration biological retention facility. By setting up a liquid level switch and a valve, when the water storage chamber inside the infiltration and drainage module reaches the preset liquid level, the liquid level switch is triggered to control the valve to open, and the rainwater inside the infiltration and drainage module is discharged from the drainage pipe. When the water storage chamber inside the infiltration and drainage module is lower than the preset liquid level, the liquid level switch is triggered to control the valve to close, and the next circulating aeration process is started. Thus, the opening and closing action of the drainage pipe is realized through the liquid level switch and the valve, thereby achieving a quantitative drainage effect. Attached Figure Description

[0030] like Figure 1-4 The image shown is a circulating aeration bioretention facility provided in the first embodiment of this utility model, including an infiltration enhancement and drainage module 1 disposed inside the soil layer, such as... Figure 1-2 As shown, the infiltration enhancement and drainage module 1 has a hollow water storage cavity inside. The top of the module 1 has a vent 11 and a water inlet. The vent 11 is positioned higher than the water inlet to facilitate the discharge of gas from the module 1 to the soil layer. Water in the soil layer can enter the water storage cavity inside the module 1 through the water inlet. Figure 1As shown, the water inlet in this embodiment includes a first water inlet 13 and multiple second water inlets 14. The first water inlet 13 is located at the vent 11, and the second water inlets 14 are evenly distributed around the outer periphery of the first water inlet 13, thereby further improving the water intake efficiency and water intake uniformity. A drain pipe 2 is connected to one side of the permeation-enhancing and drainage module 1. A valve 3 is provided between the permeation-enhancing and drainage module 1 and the drain pipe 2. A switch 4 is provided inside the permeation-enhancing and drainage module 1. The switch 4 is signal-connected to the valve 3 to control the opening and closing of the valve 3, thereby achieving a quantitative drainage effect.
[0031] like Figure 1 As shown, the permeation-enhancing and drainage module 1 in this embodiment is composed of several permeation-enhancing and drainage units 12 spliced together. The outer edge of the permeation-enhancing and drainage unit 12 is provided with a corresponding splicing part 15, which facilitates the splicing and fixing between adjacent permeation-enhancing and drainage units 12. The permeation-enhancing and drainage unit 12 in this embodiment can be set to different shapes according to the actual application scenario, such as regular or irregular shapes such as rectangles, squares, and regular hexagons, to meet the usage requirements in different actual application scenarios.
[0032] like Figure 2 As shown, in this embodiment, valve 3 can be a rotary valve or a telescopic valve to facilitate the opening and closing of the valve. Switch 4 is a liquid level switch, which is triggered according to the actual liquid level in the water storage chamber inside the permeation and drainage module 1 to control the opening and closing of valve 3.
[0033] The specific working process of this embodiment is as follows:
[0034] The infiltration-enhancing and drainage module 1, equipped with valve 3 and switch 4, is installed inside the soil layer. Rainwater flows through the soil layer and gradually enters the water storage chamber inside the infiltration-enhancing and drainage module 1 from the inlet.
[0035] When the water level in the internal storage chamber of the infiltration and drainage module 1 reaches the preset level, the level switch is triggered to control the valve 3 to open, and the rainwater inside the infiltration and drainage module 1 is discharged from the drainage pipe 2.
[0036] When the water level in the internal storage chamber of the infiltration and drainage module 1 is lower than the preset level, the level switch is triggered to control the valve 3 to close and start the next cycle of aeration.
