Description

Technical Field

[0001] This utility model relates to the field of constructed wetland maintenance technology, and in particular to an adjustable anti-clogging device and an anti-clogging constructed wetland. Background Technology

[0002] Constructed wetlands are a water purification technology based on natural ecosystems. Through the synergistic effect of wetland plants, microorganisms, and substrate materials, they effectively remove pollutants from water bodies. Wetland plants absorb nutrients such as nitrogen and phosphorus from the water through their roots, promoting their own growth while reducing the concentration of pollutants in the water. The wetland substrate and the microbial community surrounding the plant roots can degrade organic pollutants, for example, by removing nitrogen from the water through nitrification-denitrification. In addition, the wetland substrate (such as sand, gravel, and expanded clay) has a strong adsorption capacity for suspended solids, heavy metals, and some organic pollutants in the water, effectively reducing the turbidity and pollutant concentration of the water.

[0003] However, although constructed wetland technology has a good purification capacity in terms of water quality, during long-term operation, due to the long-term interception of pollutants such as suspended solids and organic matter in the wetland substrate, these particles accumulate in the wetland substrate and gradually fill the substrate pores, resulting in reduced water permeability and easy blockage, which prevents water from infiltrating smoothly and affects the purification capacity of constructed wetlands. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable anti-clogging device and an anti-clogging constructed wetland, which can effectively increase the liquid infiltration channels in the constructed wetland substrate, allowing the liquid to flow smoothly downward through the infiltration channels, effectively avoiding clogging, and thus facilitating the purification of water quality by the constructed wetland and improving the water purification efficiency.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An adjustable anti-clogging device, comprising:

[0007] The shell is a closed structure that extends vertically through the artificial wetland;

[0008] An anti-clogging component is slidably inserted through the housing and mounted on the housing. The anti-clogging component can selectively adjust the housing to be in a closed state or an open state.

[0009] An adjustment assembly, comprising an air exchange pump connected to the housing, wherein the air exchange pump can selectively inject or draw air into the housing to drive the anti-clogging assembly to slide back and forth along the inner to outer side of the housing.

[0010] Furthermore, the housing surface is provided with a through mounting hole, and the anti-clogging component includes an anti-clogging member and a positioning member. The positioning member is fixedly installed at one end of the mounting hole near the inner side of the housing. The anti-clogging member is slidably sleeved on the positioning member and can slide back and forth along the axial direction of the mounting hole by the air exchange pump to close or open the mounting hole channel.

[0011] Furthermore, the positioning component includes a base and a positioning rod. The base is fixed to one end of the mounting hole near the inner side of the housing. The positioning rod is fixed to the base along the axial direction of the mounting hole. The anti-blocking component is slidably sleeved on the positioning rod.

[0012] Furthermore, the base is cross-shaped, and a limiting groove is provided at the center of the base, into which the positioning rod can be inserted.

[0013] Furthermore, the anti-blocking component includes a sleeve rod and an anti-blocking plate. The anti-blocking plate can cover the outside of the mounting hole. One end of the sleeve rod is fixedly connected to the anti-blocking plate, and the other end of the sleeve rod is sleeved with the positioning rod. The anti-blocking plate and the sleeve rod can slide back and forth along the axial direction of the positioning rod to close or open the mounting hole channel.

[0014] Furthermore, the anti-blocking component also includes a return spring, which is sleeved on the outside of the positioning rod and can act on the sleeve rod to facilitate the reset of the sleeve rod.

[0015] Furthermore, the mounting hole is funnel-shaped, with the larger end of its opening located on the outside of the housing and the smaller end located on the inside of the housing.

[0017] Furthermore, multiple anti-blocking components are spaced apart along the surface of the housing.

[0018] A clog-resistant constructed wetland includes a pool body, a drainage layer, a filler layer, a soil layer, and a drainage pipe. The drainage layer, filler layer, and soil layer are sequentially laid from bottom to top inside the pool body. The drainage pipe is located on the lower side of the outer wall of the pool body to discharge purified liquid from the pool body. The clog-resistant constructed wetland further includes an adjustable clog-resistant device and a guide layer as described above. The adjustable clog-resistant device is located inside the pool body and sequentially penetrates the drainage layer, the filler layer, and the soil layer. The guide layer is inclined within the soil layer, with its higher end connected to the inner wall of the pool body and its lower end extending into the soil layer.

[0019] The beneficial effects of this utility model are:

[0020] This invention provides an adjustable anti-clogging device and an anti-clogging constructed wetland, including a shell, an anti-clogging component, and an adjustment component. Through the coordinated operation of the adjustment component and the anti-clogging component, the adjustment component regulates the injection or extraction of airflow, effectively driving the anti-clogging component to slide back and forth along the inner to outer side of the shell. The anti-clogging component can automatically adjust the closed or open state of the shell as needed, reducing human interference.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0028] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0029] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0030] Please refer to Figures 1 to 3 As shown, this utility model provides an adjustable anti-clogging device that can effectively increase the liquid infiltration channels within the constructed wetland substrate, allowing the liquid to flow smoothly downwards through the infiltration channels, effectively preventing clogging, and thus facilitating water purification in the constructed wetland and improving water purification efficiency. The adjustable anti-clogging device includes a housing 1, an anti-clogging component 2, and an adjustment component. The housing 1 is a closed structure that extends vertically through the constructed wetland. The anti-clogging component 2 is slidably inserted into and installed on the housing 1, and can selectively adjust the housing 1 to be in a closed or open state. The adjustment component includes an air exchange pump connected to the housing 1, which can selectively inject or draw air into the housing 1 to drive the anti-clogging component 2 to slide back and forth along the inner to outer side of the housing 1.

[0031] Through the coordinated operation of the adjusting component and the anti-blocking component 2, the anti-blocking component 2 can slide back and forth along the inner to outer side of the shell 1 under the drive of the adjusting component. The anti-blocking component 2 can automatically adjust the closed or open state of the shell 1 as needed through the adjusting component, effectively preventing matrix blockage, achieving automatic adjustment, and reducing manual intervention. When the air pump injects air into the shell 1, the gas enters the shell 1, generating pressure that drives the anti-blocking component 2 to slide outward. During the sliding process of the anti-blocking component 2, it causes slight displacement or loosening of the soil layer outside the shell 1, thereby forming seepage cracks. Furthermore, the air pump injects air into the shell 1... During aeration, the gas-driven anti-clogging component 2 keeps the shell 1 open, allowing gas to be injected into the soil layer through the open channels. The airflow causes minor structural changes in the soil layer outside the shell 1, loosening the soil, increasing the gaps in the outer soil layer, and creating seepage cracks. These seepage cracks allow liquid to flow smoothly downwards through the soil layer, preventing flow obstruction caused by the accumulation of solid deposits and blockages, keeping the seepage channels unobstructed, and ensuring that the liquid is evenly distributed and fully contacts the substrate. This facilitates water purification by the constructed wetland and improves its water purification efficiency. When the shell 1 is open, some loose soil in the outer soil layer will slide or fall into the shell 1 due to gravity. Especially during aeration, the airflow's interference with the soil layer increases, causing some soil particles to shift and enter the shell 1. The entry of soil particles into the shell 1 further reduces the density of the outer soil layer, reducing the soil content and helping to maintain a loose soil state, thus preventing the soil layer from becoming too compacted and causing blockages. Furthermore, when too much soil particles fall into the shell 1, an air exchange pump can be used to suck in air and remove the soil particles, keeping the air passages inside the shell 1 unobstructed. This can be understood as the air exchange pump adjusting the air injection rate, which in turn drives the anti-clogging component 2 to adjust the opening size of the shell's open passages, thereby controlling the amount of soil entering the shell and thus controlling the looseness of the substrate.

[0032] like Figure 2As shown, to improve the stability of the anti-clogging component 2, in some embodiments, a through mounting hole is provided on the surface of the housing 1. The anti-clogging component 2 includes an anti-clogging member 21 and a positioning member 22. The positioning member 22 is fixedly installed at one end of the mounting hole near the inner side of the housing 1. The anti-clogging member 21 is slidably sleeved on the positioning member 22 and can be driven by an air exchange pump to reciprocate along the axial direction of the mounting hole to close or open the mounting hole channel. The mounting hole provides a fixed mounting position for the anti-clogging component 2. The positioning member 22 is installed inside the housing 1 and fixed at one end of the mounting hole, so that the anti-clogging member 21 will not shift during sliding, ensuring its initial stability. The device moves along the axis of the mounting hole without tilting or jamming. The anti-clogging component 21 is fitted onto the positioning component 22, controlling its sliding path and ensuring effective sealing or opening of the mounting hole. Furthermore, the air pump drives the anti-clogging component 21 to slide, enabling automatic adjustment of its state and reducing manual intervention. When the air pump injects air into the housing 1, it drives the anti-clogging component 21 to slide outward, opening the mounting hole and allowing gas inside the housing 1 to flow into the artificial wetland substrate, increasing the seepage channel. When the air pump sucks in air, the anti-clogging component 21 returns to its initial position, sealing the mounting hole and preventing excessive soil from entering the housing 1, while simultaneously sucking away and removing soil from inside the housing 1.

[0033] like Figure 3 As shown, specifically, the positioning component 22 includes a base 221 and a positioning rod 222. The base 221 is fixed to one end of the mounting hole near the inner side of the housing 1. The positioning rod 222 is fixed to the base 221 along the axial direction of the mounting hole. The anti-blocking component 21 is slidably sleeved on the positioning rod 222. The base 221 is fixed to the inner side of the mounting hole, which improves the rigidity of the overall mounting component, provides reliable support for the positioning rod 222, prevents the positioning rod 222 from loosening during long-term use, and improves the durability of the positioning component 22. The positioning rod 222 provides a guiding function for the anti-blocking component 21, which can slide along the positioning rod 222. Since the anti-blocking component 21 is sleeved on the positioning rod 222, the contact surface is smaller, resulting in less frictional resistance compared to sliding directly against the wall of the mounting hole. This makes the sliding smoother, reduces the risk of jamming, and improves the accuracy of the sliding of the anti-blocking component 21.

[0034] To improve the uniformity of airflow distribution, in some embodiments, the base 221 is cross-shaped, with a limiting groove at its center, into which the positioning rod 222 can be inserted. The cross-shaped base 221 forms channels in four directions, allowing the gas delivered by the air exchange pump to flow evenly to all parts of the anti-blocking component 21 without generating eddies or uneven air pressure due to obstruction by the base 221, thus ensuring the smooth sliding of the anti-blocking component 21. The limiting groove constrains the position of the positioning rod 222, preventing it from shifting. After the positioning rod 222 is inserted into the limiting groove, it will not shift under external force, ensuring that the anti-blocking component 21 always slides along the axis of the mounting hole.

[0035] To ensure smooth sliding of the anti-blocking component 21, in some embodiments, the anti-blocking component 21 includes a sleeve rod 211 and an anti-blocking plate 212. The anti-blocking plate 212 can cover the outside of the mounting hole. One end of the sleeve rod 211 is fixedly connected to the anti-blocking plate 212, and the other end of the sleeve rod 211 is sleeved with the positioning rod 222. The anti-blocking plate 212 and the sleeve rod 211 can slide back and forth along the axial direction of the positioning rod 222 to close or open the mounting hole channel. The sliding guide structure formed between the sleeve rod 211 and the positioning rod 222 enables the anti-blocking component 21 to slide smoothly and reduce friction. The anti-blocking plate 212 can cover the outside of the mounting hole. When the housing 1 is in a closed state, it can effectively improve the sealing effect and prevent mud or foreign objects from entering the interior of the housing 1.

[0036] To achieve automatic reset of the anti-blocking component 21, in some embodiments, the anti-blocking assembly 2 further includes a reset spring 23. The reset spring 23 is sleeved on the outside of the positioning rod 222 and can act on the sleeve rod 211 to facilitate the reset of the sleeve rod 211. By sleeved with the reset spring 23 on the outside of the positioning rod 222, it is ensured that the sleeve rod 211 and the anti-blocking plate 212 automatically reset after the air exchange pump stops operating. When the air exchange pump stops injecting or drawing air into the housing 1, the reset spring 23 provides elastic force, causing the anti-blocking component 21 to quickly return to its original position (usually a closed state) without additional power intervention, improving the automation level of the device, preventing the mounting hole from remaining open for extended periods, and reducing the risk of mud or impurities entering the housing 1. Furthermore, an anti-collision component is provided at the end of the positioning rod 222 that contacts the anti-blocking plate 212. The anti-collision component is made of a soft and elastic material, which can effectively absorb the impact force generated during the sliding of the anti-blocking plate 212, preventing direct contact between the two and extending the service life of the structure. The anti-collision component can be, but is not limited to, silicone pads, etc., and is not specifically limited here.

[0037] To increase the driving force of the regulating component, in some embodiments, the mounting hole is funnel-shaped, with the larger diameter end located on the outside of the housing 1 and the smaller diameter end located on the inside of the housing 1. When gas is blown out from the smaller diameter end into the funnel-shaped mounting hole, the gas expands as the diameter gradually increases, resulting in a decrease in airflow velocity and an increase in pressure. This expansion effect forms a thrust concentration zone, making the anti-blocking component 21 at the larger diameter end more evenly stressed. This avoids turbulence or unstable pressure distribution when the airflow contacts the anti-blocking component 21, thereby improving the responsiveness of the anti-blocking component 21.

[0038] To improve the flexibility of the airflow path of the regulating component, in some embodiments, the regulating component further includes a ventilation pipe 3. One end of the ventilation pipe 3 is connected to the housing 1, and the other end is connected to a ventilation pump. By providing the ventilation pipe 3, the ventilation pump can be installed in a more suitable position, ensuring that the airflow is evenly delivered into the housing 1 without being limited by the structure of the housing 1, thus improving the flexibility of the airflow path of the regulating component. Simultaneously, it avoids directly fixing the ventilation pump to the housing 1, helping to reduce damage caused by equipment vibration or external forces. It is understood that the ventilation pipe 3, located on the lower side of the housing 1, can better absorb and remove soil inside the housing 1.

[0039] To further improve anti-clogging efficiency, in some embodiments, multiple anti-clogging components 2 are spaced apart along the surface of the housing 1. These multiple anti-clogging components 2 are distributed at different locations, enabling them to act simultaneously on multiple seepage channels, ensuring the uniformity of the airflow and liquid infiltration process and preventing localized blockage. Typically, the upper layer of an artificial wetland is mostly soil 7, which is more prone to clogging. Therefore, multiple anti-clogging components 2 can be positioned above the transverse central axis of the housing 1, allowing the anti-clogging components 2 to apply greater airflow pressure to the soil layer requiring dredging, ensuring the unobstructed flow of the seepage channels.

[0040] like Figure 1 As shown, this utility model also provides an anti-clogging constructed wetland, including a pool body 4, a drainage layer 5, a filler layer 6, a soil layer 7, a drainage pipe 8, a guide layer 9, and an adjustable anti-clogging device as described in any of the above embodiments. The pool body 4 is lined with the drainage layer 5, the filler layer 6, and the soil layer 7 sequentially from bottom to top. The drainage pipe 8 is located on the lower side of the outer wall of the pool body 4 to discharge the purified liquid inside the pool body 4. The adjustable anti-clogging device is located inside the pool body 4 and sequentially penetrates the drainage layer 5, the filler layer 6, and the soil layer 7. The guide layer 9 is inclined within the soil layer 7, with its higher end connected to the inner wall of the pool body 4 and its lower end extending into the soil layer 7. The adjustable anti-clogging device regulates the injection or extraction of airflow through the adjustment component, which can effectively drive the anti-clogging component 2 to achieve automatic adjustment, reduce human interference, and effectively increase the seepage channel, thereby avoiding long-term blockage caused by soil or dirt deposition in the constructed wetland and maintaining smooth liquid flow. The inclined design of the guide layer 9 helps to guide sewage and other fluids along a specific path, ensuring that they can flow smoothly to the bottom. At the same time, when there is airflow flowing upward in the adjustable anti-clogging device, the guide layer 9 can effectively guide the airflow, thereby avoiding the impact of airflow on the soil layer 7 and surface vegetation, and ensuring the stability of the constructed wetland ecosystem.

[0041] Furthermore, the filler layer 6 comprises gravel and sand, which creates numerous porous spaces, allowing water to flow smoothly. The drainage layer 5 comprises pebbles, which have excellent drainage properties, helping water to pass through the drainage layer 5 quickly and preventing excessive water retention or accumulation in the soil layer 7, thereby improving drainage efficiency.

[0042] It is understandable that vegetation is planted on the surface of soil layer 7, while microorganisms fill the filler layer 6. The plants on the surface of soil layer 7 can absorb harmful substances from the water, especially heavy metals, organic matter, and nitrogen and phosphorus, through their roots. The microorganisms in filler layer 6 can decompose organic matter, pollutants, nitrogen, and phosphorus in the water through aerobic or anaerobic degradation. Therefore, the adsorption by plants in soil layer 7 and filler layer 6, and the biodegradation by microorganisms, work together to achieve the effect of water purification in the constructed wetland. It is also understandable that the adjustable anti-clogging device, which runs sequentially through drainage layer 5, filler layer 6, and soil layer 7, can prevent the roots of plants in soil layer 7 from growing downwards indefinitely, thereby reducing the impact of upward-flowing gases on the plants.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
