Description

Technical Field

[0001] This utility model relates to the field of environmental protection technology, specifically to a floating dock oil pollution interception and adsorption device. Background Technology

[0002] Floating dock oil spill interception and adsorption device is an environmental protection equipment specially designed for ports, docks and other water areas. It collects and removes floating oil, chemical spills and other floating pollutants on the water surface by combining physical interception and adsorption materials, preventing the spread of pollution and protecting the marine ecological environment.

[0003] According to the patent application published on the Internet (authorization announcement number: CN222374440U), "This utility model belongs to the field of environmental emergency response technology and discloses a water pollution and oil spill interception device, including an interception sleeve. One end of the interception sleeve is equipped with a locking block, and one side of the locking block is provided with several mounting holes. The other end of the interception sleeve is provided with a locking seat, and both sides of the locking seat are provided with several mounting holes. A connecting rope is installed at the bottom of one side of the locking seat, and the other end of the connecting rope is equipped with a column. Several trapezoidal grooves are provided around the periphery of the column. A fixing mechanism is installed at the top of one side of the locking seat. A pair of first mounting seats are symmetrically installed on one side of the interception sleeve, and a slider is slidably installed between the pair of first mounting seats. Several oil-absorbing plates are installed on one side of the slider. Threaded holes are provided at both ends of the pair of first mounting seats and both ends of the slider. This device can quickly install and disassemble a single interception sleeve, thereby realizing the adjustment of the overall length of the interception device, improving the flexibility and adaptability of the interception device. At the same time, the interception effect of the interception device is improved by setting the oil-absorbing plates." Regarding the above description, the applicant believes the following problems exist: The device is assembled using locking blocks and brackets, with ropes threaded through the column and limiting sleeves for fixation. A guide line is used to adjust its position, a sponge ensures buoyancy, and the oil-absorbing plate absorbs oil. Disassembly involves sliding the limiting sleeve to remove the components. The oil-absorbing plate is fixed with bolts and can be replaced. However, the device relies on natural water flow to push oil to the oil-absorbing plate. In still water or slow-moving water, oil easily spreads and bypasses the plate, resulting in low oil absorption efficiency. Furthermore, the device's depth is fixed, which cannot accommodate multi-layered oil distribution. Deep, heavy oil easily leaks from the bottom, while light, floating oil leaves most areas of the oil-absorbing plate idle and may even attract mud and sand, contaminating the plate. This leads to poor device adaptability. Additionally, the oil-absorbing plate is fixed with bolts, requiring individual bolt removal for replacement, which is time-consuming and labor-intensive, increasing the user's workload. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a floating dock oil pollution interception and adsorption device, which has the following features: increasing the efficiency of oil adsorption by rotating components; allowing users to adjust the depth of the device according to the distribution of oil pollution by using a water level adjustment component, thereby increasing the adsorption range and adaptability of the device; and enabling users to quickly replace the oil adsorption plate by using a quick replacement component, thereby reducing the labor intensity of the user.

[0005] The objective of this utility model is achieved through the following technical solution: A floating dock oil spill interception and adsorption device includes a housing, a waterproof motor, and a rotating assembly. A float is mounted on the outside of the housing, with a connecting seat rotatably connected to one side of the float and a connecting block rotatably connected to the other side. A waterproof bolt is threaded into the connecting seat. The rotating assembly is located inside the housing. The waterproof motor is fixedly connected to the top of the housing, and a waterproof lead screw is fixedly connected to the output end of the motor. A sliding block is threaded into the lead screw. A second sliding block is fixedly connected to the outside of the float, and a limit rod is slidably connected inside the second sliding block. An oil-absorbing plate is slidably connected inside the housing, and a handle is fixedly connected to the top of the oil-absorbing plate. A second housing is fixedly connected to the top of the housing, and a waterproof spring is fixedly connected inside the second housing. A sliding limit block is fixedly connected to one side of the waterproof spring, and a sliding button is fixedly connected to the top of the sliding limit block.

[0006] In one optional embodiment, the oil suction plate has a through hole, and the sliding limit block is slidably connected to the inside of the oil suction plate through the through hole.

[0007] In one optional embodiment, a through hole is provided on the outer casing, and the sliding button is slidably connected to the inside of the outer casing through the through hole.

[0008] In one optional embodiment, a through hole three is provided on the outer casing one, and the waterproof screw is rotatably connected to the inside of the outer casing one through the through hole three.

[0009] In one alternative implementation, when the waterproof motor rotates clockwise, the float moves upward, and when the waterproof motor rotates counterclockwise, the float moves downward.

[0010] In one optional embodiment, the rotating assembly includes a mounting bracket, which is fixedly connected to the inner side of the housing, and a waterproof motor is fixedly connected to one side of the mounting bracket. A blade is fixedly connected to the output end of the waterproof motor.

[0011] In one optional embodiment, a through hole four is provided on the outer casing one, and the blade is rotatably connected to the inside of the outer casing one through the through hole four.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By starting the waterproof motor, the waterproof screw rotates, which in turn drives the sliding block to move up and down. The sliding block then drives the float to move up and down, allowing the user to adjust the depth of the outer casing in the water by adjusting the height of the float. This allows the user to adjust the depth of the device according to the distribution of oil stains, thereby increasing the adsorption range and adaptability of the device. Subsequently, by starting the rotating component, the water flows towards the oil suction plate, which then adsorbs the oil stains in the water, thus increasing the efficiency of the oil suction plate in adsorbing oil stains.

[0013] 2. When the oil suction plate needs to be replaced, the user moves away from the oil suction plate by sliding the sliding button, thereby causing the sliding limit block to move away from the through hole of the oil suction plate, thus releasing the limitation on the oil suction plate. Then, the user takes out the oil suction plate, puts the clean oil suction plate into the outer casing, and then releases the sliding button. Driven by the elasticity of the waterproof spring, the sliding limit block slides into the oil suction plate, thereby limiting and fixing the oil suction plate. This facilitates the user to quickly replace the oil suction plate and reduces the user's labor intensity. Attached Figure Description

[0020] Once oil spills enter water bodies, they rapidly spread and form an oil film, causing multi-dimensional harm to the ecological environment. In marine ecosystems, the oil film blocks the exchange of gases between seawater and air, leading to a sharp drop in dissolved oxygen levels underwater, causing fish, shellfish, and other aquatic organisms to die from oxygen deprivation. Toxic substances such as polycyclic aromatic hydrocarbons in oil spills accumulate in marine organisms and are passed to humans through the food chain, increasing the risk of cancer and neurological diseases. At the same time, oil pollution also damages coastal wetlands, mangroves, and other ecosystems, which often require decades to recover. Oil films covering the water surface affect the photosynthesis of aquatic plants, causing plant death and disrupting the entire aquatic food chain. In addition, oil can adhere to the feathers of birds, causing them to lose their ability to insulate themselves and fly, resulting in bird deaths. For coastal tourist areas, oil pollution makes beaches dirty and unsightly, affecting tourism development and causing huge losses to the local economy. Traditional methods for handling oil spills at docks have significant limitations. Oil booms, a commonly used interception tool, fail to function effectively when water flow exceeds 1.5 knots and are ill-suited to complex tidal changes. Oil booms typically consist of a floating body and a skirt; the floating body floats on the surface while the skirt submerges to block oil. However, in strong currents or with large tidal variations, oil booms are easily deformed or even overturned by the force of the water flow, allowing oil to escape from below or the sides. While absorbent materials like oil-absorbing mats are easy to use, their absorption capacity is limited, generally only able to absorb 5-10 times their own weight. Oil spills can be several times larger than the amount of oil itself, and the cost of recycling and treating the oil after absorption is high, which can easily cause secondary pollution. Oil-absorbing pads need to be collected and treated after absorbing oil. If not handled properly, the absorbed oil may leak again, causing new pollution. Although the use of chemical dispersants can accelerate the decomposition of oil, it can cause irreversible damage to marine microorganisms. Many countries have strictly limited its use. Chemical dispersants disperse oil into tiny particles, making it easier for microorganisms to decompose, but at the same time, they can also destroy the living environment of marine microorganisms and affect the balance of the marine ecosystem. These problems make the development of efficient and flexible oil pollution control technologies an urgent need in the field of port environmental protection. Floating dock oil pollution interception and adsorption devices are a new type of environmental protection equipment that has emerged in this context. They integrate interception, adsorption, and collection functions and can adapt to complex dock water environments. The device adopts a modular design and is mainly composed of four parts: a floating system, an interception structure, an adsorption unit, and a collection device. The modules are combined with high-strength connectors, and the length and layout can be flexibly adjusted according to the actual needs of the dock. Whether it is local protection for small docks or comprehensive prevention and control for large ports, effective oil pollution control can be achieved through reasonable module configuration. The floating system is the basic support component of the device. It typically uses floats made of high-density polyethylene or reinforced polypropylene, materials with excellent corrosion resistance, capable of withstanding seawater, oil, and other harmful substances, extending the device's service life. The floats employ a closed-cell foam structure, providing excellent buoyancy stability, maintaining overall buoyancy even if parts of the device are damaged. The floats have a wide operating temperature range, functioning normally even in extreme temperatures from -30℃ to 60℃, making them suitable for docks in various climates. The floats are connected by hinges, forming a flexible, bendable structure that allows the device to rise and fall freely with waves and tides, ensuring the interception section remains at the optimal working depth and effectively preventing the spread of oil. To enhance stability, large devices are also equipped with detachable counterweights and an anchoring system. The counterweights can be adjusted according to actual conditions to maintain a stable posture in the water, while the anchoring system firmly secures the device in a designated location, withstanding winds and waves of force 8 or higher, ensuring normal operation even in severe weather conditions. The interception structure plays a crucial role in preventing the spread of oil slicks. The surface interception uses high-strength nylon mesh, which boasts high tensile strength and abrasion resistance, capable of withstanding the impact of water flow and oil slicks. With a mesh diameter of approximately 2 mm, it effectively blocks larger oil clumps, preventing their spread through the mesh, without excessively obstructing water flow and reducing the impact on the device. The mesh surface undergoes a hydrophobic treatment, giving it the properties of repelling water and adsorbing oil slicks. When oil slicks come into contact with the mesh surface, they are adsorbed, while water can pass through smoothly, improving interception efficiency. The underwater interception section uses a skirt made of elastic rubber. Elastic rubber has excellent flexibility and elasticity, adapting to changes in water flow and the undulations of the device. The skirt's vertical depth can reach 1-3 meters, effectively preventing oil slicks from escaping underwater and forming a three-dimensional interception barrier. A counterweight chain is installed at the bottom of the skirt; the weight of the counterweight chain ensures the skirt remains vertical under the impact of water flow, preventing the skirt from being lifted by the water flow and creating interception gaps, thus ensuring the integrity of the interception structure. The adsorption unit is the core of the device for purifying oily waste. It is made of composite oil-absorbing materials, typically based on polypropylene fibers. Polypropylene fibers have good chemical stability and oleophilicity, making them an ideal base material for oil-absorbing materials. After special processing, the polypropylene fibers form a three-dimensional network structure. This structure greatly increases the specific surface area of ​​the material and improves its oil absorption capacity, achieving an oil absorption capacity of 20-30% of its own weight. The oil absorption efficiency is several times higher than that of traditional oil-absorbing materials. The material surface has hydrophilic and oleophobic properties, which allows the material to expel water while absorbing oil, greatly improving the absorption efficiency and preventing the material from affecting the oil absorption effect due to excessive water absorption. The adsorption unit is designed with a replaceable modular structure. When the adsorption reaches saturation, the staff can quickly replace it with a new unit. The old unit can be reused after being squeezed to remove oil, reducing operating costs. The modular structure also facilitates the maintenance and repair of the adsorption unit, improving the operation and maintenance efficiency of the device. Some high-end devices also add nano-catalysts to the adsorption unit. Nano-catalysts have high catalytic activity and can initially degrade oil during the adsorption process, decomposing some oil into harmless substances, reducing the pressure of subsequent treatment and improving the overall effect of oil pollution control.

[0021] Please see Figures 1-6This utility model provides an embodiment of a floating dock oil spill interception and adsorption device, including a housing 1, a waterproof motor 601, and a rotating assembly. A float 2 is disposed on the outside of the housing 1. A connecting seat 3 is rotatably connected to one side of the float 2, and a connecting block 4 is rotatably connected to another side of the float 2. A waterproof bolt 5 is threaded into the connecting seat 3. A rotating assembly is disposed inside the housing 1. The waterproof motor 601 is fixedly connected to the top of the housing 1. A waterproof lead screw 604 is fixedly connected to the output end of the waterproof motor 601. A sliding block 605 is threaded into the external end of the waterproof lead screw 604. The float 2 is externally fixedly connected to... There is a second sliding block 607, and a limit rod 606 is slidably connected inside the second sliding block 607. An oil suction plate 603 is slidably connected inside the first outer shell 1. A handle 602 is fixedly connected to the top of the oil suction plate 603. An outer shell 608 is fixedly connected to the top of the first outer shell 1. A waterproof spring 609 is fixedly connected inside the second outer shell 608. A sliding limit block 610 is fixedly connected to one side of the waterproof spring 609. A sliding button 611 is fixedly connected to the top of the sliding limit block 610. By inserting the connecting block 4 into the connecting seat 3, and then connecting and fixing the connecting block 4 to the waterproof bolt 5 by rotating the waterproof bolt 5, it is convenient to connect multiple of this device. Connecting the components allows for adjustment of the device's interception length based on usage. Starting the waterproof motor 601 rotates the waterproof lead screw 604, which in turn moves the sliding block 605 up and down. The sliding block 605 then moves the float 2 up and down, allowing adjustment of the float 2's height to regulate the depth of the outer casing 1 in the water. This allows users to adjust the device's depth according to oil distribution, increasing the device's adsorption range and adaptability. Subsequently, activating the rotating assembly directs water flow towards the oil-absorbing plate 603, which then adsorbs the oil in the water, further increasing the adsorption capacity. The oil absorption plate 603 has a high efficiency in absorbing oil stains. When the oil absorption plate 603 needs to be replaced, the user slides the sliding button 611 away from the oil absorption plate 603, thereby causing the sliding limit block 610 to move away from the through hole of the oil absorption plate 603, thus releasing the limitation on the oil absorption plate 603. Then, the user takes out the oil absorption plate 603, puts the clean oil absorption plate 603 into the outer casing 1, and then releases the sliding button 611. Driven by the elasticity of the waterproof spring 609, the sliding limit block 610 slides into the oil absorption plate 603, thereby limiting and fixing the oil absorption plate 603. This facilitates the user to quickly replace the oil absorption plate 603, thereby reducing the user's labor intensity.

[0022] In a preferred embodiment of this utility model, the oil-absorbing plate 603 is provided with a through hole, and the sliding limiting block 610 is slidably connected to the inside of the oil-absorbing plate 603 through the through hole, which is beneficial for the sliding limiting block 610 to limit the oil-absorbing plate 603, thereby facilitating the fixing of the oil-absorbing plate 603 inside the outer shell 1.

[0023] In a preferred embodiment of this utility model, a through hole 2 is provided on the outer shell 2 608, and the sliding button 611 is slidably connected to the inside of the outer shell 2 608 through the through hole 2, which makes it easier for the user to move the sliding limit block 610 by moving the sliding button 611, so that the sliding limit block 610 leaves the through hole of the oil suction plate 603.

[0024] In a preferred embodiment of this utility model, a through hole 3 is provided on the outer shell 1, and the waterproof lead rod 604 is rotatably connected to the inside of the outer shell 1 through the through hole 3. This facilitates the waterproof motor 601 to drive the waterproof lead rod 604 to rotate, which in turn facilitates the waterproof lead rod 604 to drive the sliding block 605 to perform lifting and lowering movements.

[0025] In a preferred embodiment of this utility model, when the waterproof motor 601 rotates clockwise, the float 2 moves upward and when the waterproof motor 601 rotates counterclockwise, the float 2 moves downward, which makes it easier for the user to adjust the depth of the device in water by rotating the waterproof motor 601 in both directions.

[0026] Please see Figure 3 and Figure 5 In this embodiment, the rotating assembly includes a mounting bracket 701, which is fixedly connected to the inner side of the outer casing 1. A waterproof motor 702 is fixedly connected to one side of the mounting bracket 701, and a paddle 703 is fixedly connected to the output end of the waterproof motor 702. By starting the waterproof motor 702, the paddle 703 is driven to rotate. The rotating paddle 703 drives the water to flow into the interior of the device, thereby allowing the oil in the water to be absorbed by the oil suction plate 603.

[0027] In a preferred embodiment of this utility model, a through hole four is provided on the outer shell 1, and the blade 703 is rotatably connected to the inside of the outer shell 1 through the through hole four, which is conducive to the waterproof motor 2 702 driving the blade 703 to rotate, thereby facilitating the blade 703 to drive the water flow.

[0028] During operation, the connecting block 4 is inserted into the connecting seat 3, and then the connecting block 4 is connected and fixed to the waterproof bolt 5 by rotating the waterproof bolt 5. This facilitates the connection of multiple devices and allows for adjustment of the interception length of the device according to usage. Starting the waterproof motor 601 drives the waterproof lead screw 604 to rotate, which in turn drives the sliding block 605 to move up and down. The sliding block 605 then drives the float 2 to move up and down, allowing the user to adjust the depth of the outer shell 1 in the water by adjusting the height of the float 2. This allows the user to adjust the depth of the device according to the distribution of oil stains, increasing the adsorption range and adaptability of the device. Subsequently, starting the waterproof motor 702 drives the blade 703 to rotate. The rotating blade... 703 drives water to flow into the interior of the device, thereby absorbing the oil in the water by the oil suction plate 603, thus increasing the efficiency of the oil suction plate 603 in absorbing oil. When the oil suction plate 603 needs to be replaced, the user slides the sliding button 611 away from the oil suction plate 603, thereby causing the sliding limit block 610 to leave the through hole of the oil suction plate 603, thus releasing the limitation on the oil suction plate 603. Then the user takes out the oil suction plate 603, puts the clean oil suction plate 603 into the outer casing 1, and then releases the sliding button 611. The sliding limit block 610 slides into the oil suction plate 603 under the force of the waterproof spring 609, thereby limiting and fixing the oil suction plate 603. This facilitates the user to quickly replace the oil suction plate 603, thereby reducing the user's labor intensity.

[0029] Although only certain components and embodiments of this application have been illustrated and described, many modifications and alterations (e.g., variations in the size, dimensions, structure, shape and proportion of the various elements, installation arrangement, material use, color, orientation, etc.) will be conceived by those skilled in the art without actually departing from the scope and spirit of the claims.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
