Description

Technical Field

[0001] The present invention relates to the technical field of garbage cleaning and sewage purification, and specifically to a river garbage cleaning and sewage purification device and an ecological floating island system thereof. Background Art

[0002] Litter pollution in rivers is primarily caused by human activities, including but not limited to carelessly discarded household garbage, industrial waste, and pesticide and fertilizer residues in agricultural runoff. These pollutants not only impact the natural landscape of rivers but can also spread through water flows to wider areas, affecting water quality. Litter accumulation on riverbeds alters water flow, potentially increasing the risk of localized flooding. Furthermore, some persistently biodegradable materials, such as plastics, persist in the environment, threatening aquatic life and potentially impacting human health through the food chain.

[0003] Currently, river garbage removal relies primarily on manual salvage, a method that is inefficient, labor-intensive, and unable to promptly remove large amounts of floating garbage.

[0016] The principle and beneficial effects of the technical solution are:

[0017] 1. The present invention provides a river garbage cleaning and sewage purification device and its ecological floating island system. The fixing parts at the bottom of the box are used to fix the box to the bottom of the river. The box is provided with an inlet and an outlet. Water flows into the box from the inlet and flows out of the box from the outlet after garbage filtering and sewage treatment. The first filter layer and the second filter layer are connected in sequence from the inlet to the outlet in the box, and the height of the first filter layer can be higher than the top plane of the box to prevent water from directly flowing along the top plane of the box over the first filter layer into the box. The first filter layer and the second filter layer are used to filter impurities in the water so that the treated water meets the discharge standard and can be directly discharged back to the river. The sewage purification process is simple, the labor cost is reduced, and the cost is low. A garbage collection chamber is formed between the first filter layer and the box body, and an entrance is provided at the top of the garbage collection chamber, and a connecting ring is connected to the top of the garbage collection chamber, and the connecting ring is detachably connected to an elastic net bag, so that manual or mechanical arms can take out the net bag to clean garbage, and a guide plate is connected to the side of the box body close to the net bag, and the guide plate is higher than the net bag, so that water carrying garbage can flow from the guide plate into the net bag, and the net bag can collect garbage therein; the box body is connected to a compression component, which is located just above the net bag, and a collection box is connected to the bottom of the garbage collection chamber, and the collection box is located just below the net bag, so that the garbage in the net bag can be pressed down into the collection box; a plurality of water outlet holes are provided on the side wall of the collection box, so as to drain water and leave garbage therein, and the size of the water outlet holes can be set as needed; and the top of the collection box is rotatably connected to a box cover through a connecting component, and the box body is provided with a control module, which is connected to the compression component, and the control module is connected to a battery, which provides power to the control module, and the control module controls the compression The assembly is pressed down regularly to press the garbage in the net bag into the collection box, avoiding garbage accumulation and causing water flow obstruction. It can also compress the garbage and reduce the area occupied by the garbage, thereby reducing the frequency of cleaning, which is more efficient, saves labor costs, and can clean up the garbage in time. In addition, the bottom of the collection box is rotatably connected to the box cover through a connecting assembly. When the compression assembly is pressed down to contact the box cover, the compression assembly pushes the box cover to rotate downward to push the garbage into it. During this process, the compression assembly maintains contact with the box cover. After pushing the garbage into the collection box, the compression assembly retracts and separates from the box cover. The box cover closes under the action of the connecting assembly to collect the garbage therein, avoiding some lighter garbage from floating up, and more fully collecting the garbage flowing through here, avoiding garbage flowing into the downstream or clogging the first filter layer and the second filter layer, reducing the frequency of manual cleaning, and can also speed up the water flow rate, improve the efficiency of garbage cleaning and sewage purification, reduce treatment costs, reduce pollution to the environment, and protect water resources and the ecological environment.

[0018] 2. The present invention provides a river garbage cleaning and sewage purification device and its ecological floating island system, wherein the connecting component includes a pivot pin and a spring, the compression component is pressed downward, the box cover rotates downward with the pivot pin as the center, and the spring is compressed, and the telescopic component retracts after the garbage is pushed in and separates from the box cover, and the rebound force of the spring causes the box cover to rotate upward to close the collection box, and the box body is provided with a horizontal limit plate to limit the upward rotation of the box cover, that is, the upper limit position of the box cover is a horizontal plane, and the cooperation of the spring and the horizontal limit plate can close the box cover to prevent the buoyancy of the water from opening the box cover, and can adapt to different water flow buoyancy.

[0019] 3. The present invention provides a river garbage cleaning and sewage purification device and its ecological floating island system. The compression assembly includes a first telescopic rod and a pressure plate. A control module controls the extension and retraction of the first telescopic rod to press garbage down into a collection box, making operation convenient. A guide plate is slidably connected to the box body along the height direction of the box body, and the box body is provided with a limiter to limit the sliding of the baffle, so that the height of the guide plate can be adjusted according to different water flow sizes and depths, thus having wide applicability. A baffle is slidably connected to the box body near the outlet, which is used to partially or completely block the outlet. The control module controls the extension and retraction of the second telescopic rod based on information transmitted by the water level sensor to adjust the outlet size. When the water level is too high, the second telescopic rod controls the sliding of the baffle to increase the outlet size, increasing the outflow rate. When the water level is too low, the second telescopic rod controls the sliding of the baffle to decrease the outlet size, thereby preventing the high water level from causing backflow at the inlet and affecting the sewage treatment effect. In addition, the first and second telescopic rods can be cleaned regularly to prevent debris in the water from clogging the telescopic rods.

[0020] 4. The present invention provides a river garbage cleaning and sewage purification device and its ecological floating island system.

The river water purified by the first filter layer is discharged into the second layer in the chassis. The second layer is provided with alumina-coated activated carbon. The adsorption properties of activated carbon are used to deeply purify organic matter, odor, etc. in the water. Metal oxides fix heavy metal ions through adsorption, chemical precipitation or redox reaction, which can effectively remove heavy metal ions in the water and enhance the adsorption capacity of arsenic, so that the treated water meets the discharge standards and can be directly discharged back into the river. A third filter layer is connected between the second filter layer and the outlet. The third filter layer includes a third filter plate. The third filter plate is provided with nanomaterials or photocatalytic materials. That is, on the basis of the existing two-layer purification system, a third-layer purification module is added, which adopts nanomaterials or photocatalytic materials (such as TiO2 coating) and uses sunlight to carry out photocatalytic reaction to further degrade difficult-to-degrade organic matter and pathogenic microorganisms in the water.

[0021] 5. The present invention provides a river garbage cleaning and sewage purification device and its ecological floating island system. A water quality sensor is provided on the inner wall of the box at the outlet. The water quality sensor is connected to the control module. The purification mode is dynamically adjusted according to the real-time data of the water quality sensor. For example, when a high concentration of oil pollution is detected, the working intensity of the oil-water separation membrane is automatically increased; when it is detected that the heavy metal ions exceed the standard, the chemical precipitation module is started. The box is provided with a camera, which is connected to the control module. The control module is remotely wirelessly connected to a mobile phone or computer. The camera can detect the garbage filling situation and adjust the working parameters of the device (such as purification intensity, garbage cleaning frequency, etc.) in real time through the remote control platform of the mobile phone or computer. It also supports remote fault diagnosis and maintenance.

For example, the width and depth of the box are designed according to the width or depth of the river, and the length, width and depth of the box are designed according to the size of the lake or the size of the required ecological floating island, or several boxes can be spliced ​​together; a floating island platform is provided on the top of the box, and the platform is made of a lightweight, corrosion-resistant material (such as high-density polyethylene). Aquatic plants (such as reeds, cattails, water lilies, cannas, etc.) are planted on the platform, and the plant roots can extend into the water to absorb nitrogen, phosphorus and some heavy metals in the water; a biological filler layer (such as biological ceramsite or biofilm) is provided under the floating island platform to provide an attachment surface for microorganisms, and the metabolism of microorganisms is used to further degrade organic matter and pollutants in the water. The ecological floating island system can not only purify water quality, but also provide habitats for aquatic organisms such as fish and insects, improve the ecological environment of rivers, and increase biodiversity; it can also be applied to some ornamental lakes with serious pollution. A water pump is set in the lake to pump water from the lake into the inlet of the box, and the outlet of the box is closed.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0033] Example 1

[0034] like Figures 1 to 3As shown, a river garbage cleaning and sewage purification device includes a housing 1, with several fixings (ground nails 2) disposed at the bottom of the housing 1, and a control module 20 disposed at the top of the housing 1. An inlet 3 is disposed at the top of the housing 1, and an outlet 4 is disposed on a side wall of the housing 1 away from the inlet 3. A first filter layer 17, a second filter layer 18, and a third filter layer 19 are sequentially connected within the housing 1 from the inlet 3 to the outlet 4. The first filter layer 17 and the second filter layer 18 are used to filter impurities from the water. The first filter layer 17 includes a first filter plate provided with an oil-water separation membrane; the second filter layer 18 includes a second filter plate provided with alumina-coated activated carbon; and the third filter layer 19 includes a third filter plate provided with a nanomaterial or photocatalytic material. To improve the water purification effect, the first filter layer 17, the second filter layer 18, and the third filter layer 19 need to be regularly maintained, for example, by replacing one filter membrane every three months.

[0035] Nanomaterials can also be replaced with other more economical materials, for example: 1. Micron-sized TiO2 is more cost-effective and requires good particle size control; 2. Diatomaceous earth after ball milling has the best cost-effectiveness and is the first choice for low-cost, multi-pollutant coordinated purification, especially suitable for mixed pollution of heavy metals and organic matter; (1) Extremely low cost: The mining cost of diatomaceous earth is about 0.5 yuan / kg, and the total cost after processing is ≤50 yuan / kg, which is 1 / 10 of that of nanomaterials (2) Environmentally friendly: Natural porous structure, no complex modification is required, and it can be naturally degraded after disposal (3) Co-purification: Diatomaceous earth itself adsorbs heavy metals, such as Pb 2 + Adsorption capacity reaches 80mg / g, complementing photocatalysis; 3. Fe2O3+zeolite complex balances high efficiency and convenient recycling, suitable for dynamic management of urban water bodies. Flexible material combinations based on pollutant type, water conditions (pH, light), and budget achieve a trinity of "low cost, high efficiency, and easy maintenance" treatment.

[0036] In practical applications, governance can be divided into stages:

[0037] Short term: Prioritize the use of ball-milled diatomaceous earth to treat heavy metal pollution (low cost, rapid adsorption).

[0038] Long-term: Introduce Fe2O3 / zeolite complex, combined with ecological floating island system (plant absorption + photocatalysis).

[0039] Intelligent regulation: Under the control of water quality sensors (monitoring pH and heavy metal concentration), materials are dynamically switched (such as enabling hematite in acidic water bodies).

[0040] Circular economy: Waste diatomaceous earth is used as roadbed material, and magnetic Fe2O3 / zeolite is recovered and reused.

Aquatic plants (such as reeds, cattails, lilies, cannas, etc.) are planted on the floating island platform 32, and the plant roots can extend into the water to absorb nitrogen, phosphorus, and some heavy metals in the water; the biological filler layer (such as biological ceramsite or biofilm) below the floating island platform 32 provides an attachment surface for microorganisms, and uses the metabolism of microorganisms to further degrade organic matter and pollutants in the water; the control module 20 controls the extension and contraction of the second telescopic rod 31 to adjust the size of the outlet 4 according to the signal transmitted by the water temperature sensor; the control module 20 judges the water quality according to the signal transmitted by the water quality sensor 25, and sends a signal to the mobile phone or computer, and the control module 20 synchronizes the image of the camera 27 to the mobile phone or computer in real time to facilitate timely handling of emergencies; when used in a lake, several boxes 1 can be spliced ​​together, and the first water pump is used to pump water in the lake into the garbage collection chamber 24 of the box 1, and the outlet 4 of the box 1 is closed, and the second water pump is used to pump the sewage treated by the box 1 into the lake.

[0055] The present invention provides a river garbage cleaning and sewage purification device, in which the deflector plate 5 is set so that water carrying garbage can flow from the deflector plate 5 into the net bag 11, and the net bag 11 can collect the garbage therein; the compression component is used to press the garbage in the net bag 11 down into the collection box 12; the side wall of the collection box 12 is provided with a plurality of water outlet holes 16 to facilitate the discharge of water and leave the garbage therein, and the size of the water outlet holes 16 can be set as needed; the control module 20 controls the compression component to press down regularly to press the garbage in the net bag 11 into the collection box 12, to avoid garbage accumulation and water flow blockage, and to compress the garbage, reduce the area occupied by the garbage, thereby reducing the frequency of cleaning, high efficiency, saving labor costs, and being able to clean up the garbage in time; in addition, the collection box The bottom of 12 is rotatably connected to the box cover 13 through a connecting assembly. When the compression assembly is pressed down to contact the box cover 13, the compression assembly pushes the box cover 13 to rotate downward to push the garbage into it. During this process, the compression assembly remains in contact with the box cover 13. After pushing the garbage into the collection box 12, the compression assembly retracts and separates from the box cover 13. The box cover 13 is closed under the action of the connecting assembly to collect the garbage therein, preventing some lighter garbage from floating up, and more fully collecting the garbage flowing through here, preventing the garbage from flowing downstream or clogging the first filter layer 17 and the second filter layer 18, reducing the frequency of manual cleaning, and speeding up the water flow rate, improving the efficiency of garbage cleaning and sewage purification, reducing treatment costs, reducing pollution to the environment, and protecting water resources and the ecological environment.

[0056] The connecting assembly includes a pivot pin 14 and a spring 15. The compression assembly is pressed down, and the box cover 13 rotates downward with the pivot pin 14 as the center, and compresses the spring 15. After the garbage is pushed in, the telescopic assembly retracts and separates from the box cover 13. The rebound force of the spring 15 causes the box cover 13 to rotate upward to close the collection box 12, and the box body 1 is provided with a horizontal limit plate 34 to limit the upward rotation of the box cover 13, that is, the upper limit position of the box cover 13 is a horizontal plane. The cooperation of the spring 15 and the horizontal limit plate 34 can close the box cover 13 to prevent the buoyancy of the water from opening the box cover 13, and can adapt to different water flow buoyancy.

[0057] A baffle 30 is slidably connected to the box body 1 near the outlet 4. The baffle 30 is used to partially or completely block the outlet 4 to adjust the size of the outlet 4. When the water level is too high, the second telescopic rod 31 is controlled to drive the baffle 30 to slide to enlarge the outlet 4 and increase the speed of water outflow. When the water level is too low, the second telescopic rod 31 is controlled to drive the baffle 30 to slide to reduce the outlet 4, thereby avoiding the water level being too high and the inlet 3 backflowing, which affects the sewage treatment effect.

[0058] A water quality sensor 25 is installed on the inner wall of the housing 1 at outlet 4. This sensor is connected to the control module 20, and the purification mode is dynamically adjusted based on the real-time data from the sensor. A camera 27 is also installed in the housing 1, connected to the control module 20, which is remotely connected to a mobile phone or computer via wireless communication. The camera 27 can monitor the garbage loading status and adjust the operating parameters of the device in real time through the remote control platform on the mobile phone or computer, and supports remote fault diagnosis and maintenance.

[0059] A plurality of solar panels 28 are provided on the top of the box 1 to convert solar energy into electrical energy to provide power for the entire device; at the same time, a storage battery is provided to continue to power the device at night or on rainy days, ensuring that the device operates uninterruptedly for 24 hours.

[0060] The present invention provides a river garbage cleaning and sewage purification device, in which an ecological floating island module is added to the top or around the box body 1 to further improve the water purification effect and provide support for the river ecosystem. Specifically, a floating island platform 32 is provided on the top of the box body 1. The platform is made of a lightweight, corrosion-resistant material. Aquatic plants are planted on the platform, and the plant roots can extend into the water to absorb nutrients such as nitrogen and phosphorus in the water. A biological filler layer is provided under the floating island platform 32 to provide an attachment surface for microorganisms, and the metabolism of microorganisms is used to further degrade organic matter and pollutants in the water. The ecological floating island system can not only purify water quality, but also provide habitats for aquatic organisms such as fish and insects, improve the ecological environment of the river, and increase biodiversity. It can also be applied to some ornamental lakes with severe pollution.

[0061] The above is only an embodiment of the present invention, and common knowledge such as the specific technical solutions or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the description can be used to interpret the content of the claims.
