Description

Technical Field

[0001] This invention relates to the field of water oil adsorption technology and provides a biomimetic aquatic plant-based oil adsorption device. Background Technology

[0002] Routine ink pollution control in urban landscape water bodies and oil pollution interception at industrial area stormwater outlets involve the continuous control and removal of oil or pollutants from the water by installing appropriate prevention and interception devices, ensuring water cleanliness and a healthy ecological environment. Urban landscape water bodies, often serving as public environmental facilities, directly impact the city's aesthetics and environmental quality through their water quality and aesthetic appeal. Therefore, controlling ink pollution has become a crucial task in urban management. Oil pollution interception at industrial area stormwater outlets, on the other hand, effectively prevents oil from entering the urban drainage system by installing interception devices before the outlets, thus preventing oil from polluting and damaging the ecological environment.

[0003] Traditional oil spill treatment technologies face a series of problems. While mechanical oil booms can intercept oil spills on the water surface to some extent, their large size often obstructs water flow and damages the natural landscape of aquatic bodies. Furthermore, mechanical oil booms are ineffective at absorbing small, dispersed oil droplets, failing to meet the needs of treating fine oil spills. Chemical oil dispersants, although capable of breaking down oil, may generate secondary pollution during use, with chemical components harming aquatic life and disrupting the ecological balance of the waterway. Commonly used oil-absorbing materials, such as polypropylene fibers, require frequent replacement after a period of use, increasing maintenance costs. Moreover, these materials are difficult to recycle and easily contribute to microplastic pollution, further burdening the aquatic environment.

[0004] Therefore, traditional oil pollution control technologies for water bodies have several drawbacks in practical applications, including ecological damage, low treatment efficiency, the risk of secondary pollution, and high operation and maintenance costs. Thus, there is an urgent need for a new type of oil pollution treatment equipment that can efficiently adsorb oil while avoiding damage to the ecological environment. Utility Model Content

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

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0026] See Figure 1-6 The purpose of this utility model is to provide an oil stain adsorption device that prevents the growth of aquatic plants, including a grid base frame 1 made of metal structure. The grid base frame 1 is made of several aluminum alloy square tubes welded together in a crisscross pattern. In this case, the grid base frame 1 is a 3*3 grid structure, that is, it is composed of 4 longitudinal beams and 4 transverse beams welded together.

[0027] Several weights 21 are installed at the bottom of the grid base 1 to provide downward weight. These weights 21 are arranged with weights at the four corners and a central support to provide downward weight, maintain the stability of the device, and prevent it from floating. Specifically, the weights 21 are made of high-density 316L stainless steel with an anti-corrosion treatment. A buoyancy frame 6 is installed at the top of the grid base 1 via a suspension cable 5. The buoyancy frame 6 uses a 5cm diameter hollow PVC pipe or hollow square tube as its main structure, filled with adjustable foam material to control its suspension in the water. Other devices for providing upward buoyancy can be installed on the buoyancy frame 6. In its natural state in the water, the weights 21 and the grid base 1 pull the entire device downward, while the buoyancy frame 6 provides upward buoyancy, thus keeping the entire device upright in the water.

[0028] The grid base frame 1 is provided with several mounting buckles 3 arranged in an array. One end of the filter fiber 7 is installed on the top of the mounting buckle 3. The other end of the filter fiber 7 can be bound to the buoyancy frame 6 by mounting hooks or mounting rings.

[0029] Specifically, the filter fiber 7 is a woven fiber bundle. The filter fiber 7 is woven from polypropylene / polyester composite fiber bundles (0.1-0.3mm in diameter) into a bundle, with an overall height of 2-3m. Hooks are installed at both ends of the filter fiber 7 along its length, or it is tied with knots. Before installing the filter fiber 7 to the mesh base frame 1, workers can first install one end of the filter fiber 7 to the buoyancy frame 6 using one or more of the aforementioned methods. Subsequently, during the overall installation, several filter fibers 7 can be installed to the mesh base frame 1 using mounting clips 3.

[0030] Preferably, the bottom of the grid base frame 1 is fixedly connected with several base frame legs 2 for fixing the weight 21. The base frame legs 2 can raise the grid base frame 1 above the bottom sediment of the water body. That is, after the device is deployed, it sinks to the bottom of the water under the influence of gravity, and the base frame legs 2 will sink into the bottom sediment to a certain extent, while their own length is sufficient to prevent the grid base frame 1 from sinking into the bottom sediment of the water body.

[0031] Preferably, a diagonal bracing beam 22 for strengthening the structure is installed between the grid base frame 1 and the base frame legs 2. Simultaneously, a mounting platform 4 for equipment installation is installed on the grid base frame 1 via platform diagonal braces 41. Various equipment for water body detection can be installed on the grid base frame 1, and the mounting platform 4 provides installation points for the equipment.

[0032] Preferably, the top of the buoyancy frame 6 is equipped with a lifting ring 61 for lifting. In use, the lifting ring 61 can serve as a fixing point for connecting lifting equipment such as cranes and lifting ropes. The entire device can be installed, moved, or operated through the lifting ring 61.

[0033] Preferably, the mounting buckle 3 is installed to the grid base frame 1 via a snap-fit ​​buckle 30. Specifically, the grid base frame 1 has several pre-drilled holes, and the snap-fit ​​buckle 30 snaps into these holes. The mounting buckle 3 and the snap-fit ​​buckle 30 are connected by bolts.

[0034] Preferably, the snap fastener 30 includes an abutment plate 301, the bottom of which is fixedly connected to a hollow insert rod 302. The insert rod 302 has a contraction groove 305, a snap-fit ​​edge 304 at its bottom, and an insertion hole 303. Thus, the snap fastener 30 can be inserted downwards into the pre-drilled hole in the grid base frame 1, and after insertion, the snap-fit ​​edge 304 engages with the grid base frame 1 to prevent it from coming loose.

[0035] Preferably, the mounting buckle 3 has a connecting ring 32 for connecting the filter fiber 7 installed at its top, and a rod 31 at its bottom with a screw hole 33 corresponding to the insertion hole 303. Thus, when the mounting buckle 3 is inserted into the snap-fit ​​buckle 30, a bolt can be screwed into the corresponding screw hole 33 and insertion hole 303 to complete the installation.

[0036] In one of the preferred embodiments, both the grid base 1 and the buoyancy frame 6 are provided with corresponding pre-drilled holes, and snap fasteners 30 are installed in each of the pre-drilled holes. At this time, mounting buckles 3 are pre-installed at both ends of the filter fiber 7 along its length. During installation, simply install the mounting buckles 3 at both ends into the corresponding snap fasteners 30 on the grid base 1 and the buoyancy frame 6, and screw in the bolts to complete the installation of the filter fiber 7. Similarly, disassembly is completed by simply unscrewing the bolts. When using this device, a single-row interception method or a matrix arrangement can be used to remove ink from the water. The single-row interception method involves arranging the filter fiber 7 along the water flow direction at 2m intervals, suitable for narrow river areas; the matrix interception method involves arranging it in a 5m×5m grid in ports or lakes to handle large-area oil spills. In application, the biomimetic swaying of the filter fiber 7 in this device improves the oil contact efficiency.

[0037] This device can be used with floating pontoons to mark the location of deployed devices. The bottom of the pontoons is connected to lifting rings 61 via cables, facilitating the installation and lifting of the device's lifting rings 61 by water-based lifting equipment. For oil spill recovery, the device is recovered first. Only the filter fibers 7 need to be disassembled; the saturated fiber clusters are lifted as a whole and placed in a centrifuge (2000 rpm, 5 minutes) for separation. The fiber clusters are then rinsed with ethanol to remove the oil, allowing for redeployment.

[0038] In summary, in practical use, staff first select either a single-row interception method or a matrix arrangement to deploy this biomimetic aquatic plant-type oil adsorption device based on the water pollution situation and geographical environment. After the device enters the water, the dropper 21, made of high-density 316L stainless steel, descends due to gravity, while the buoyancy frame 6 uses buoyancy to keep the filter fibers 7 of the entire device upright and stably suspended in the water.

[0039] As the water flows, the filter fiber 7, mimicking aquatic plants, sways naturally. Its clustered structure, woven from polypropylene / polyester composite fiber bundles, effectively increases the contact area with oil, improving adsorption efficiency. Once the oil is saturated, the entire device is retrieved by connecting the lifting ring 61 at the top of the buoyancy frame 6 using a lifting device. At this point, simply removing the bolts connecting the mounting buckles 3 and snap-fit ​​buckles 30 at both ends of the filter fiber 7 allows for the disassembly of the saturated fiber clusters, separation of the oil, and re-injection of the device. This achieves efficient recycling of the device, providing an innovative solution for water pollution control that is structurally stable, easily recyclable, and adaptable to different water environments.

[0040] Therefore, this biomimetic aquatic plant-type oil pollution adsorption device utilizes biomimetic principles and achieves stable suspension and adsorption of oil pollution through the synergistic effect of components such as the grid base frame 1, the weight 21, the buoyancy frame 6, and the filter fiber 7. At the same time, with the help of the detachable installation structure and regeneration process, the operating cost is greatly reduced, and the economy and practicality of oil pollution treatment are improved. It can be widely used in oil pollution cleaning operations in waterways such as rivers, ports, and lakes.

[0041] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
