Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine oil cleanup technology, specifically a marine oil cleanup and recovery device. Background Technology
[0002] With the increasing frequency of offshore oil extraction and transportation activities, oil spills occur frequently. The spilled oil floating on the sea surface not only causes serious damage to the marine ecological environment, such as polluting seawater, poisoning marine life, and disrupting the marine ecological balance, but also affects the development of related industries such as coastal fisheries and tourism. Therefore, it is necessary to clean up the oil on the sea surface.
[0003] However, traditional offshore oil cleanup methods typically involve using water pumps to extract oil. These pumps are inserted into the surface of the oil-bearing area and then extracted along with a large amount of seawater. This method has low oil recovery efficiency, the recovered oil is not very pure, and the extraction of large amounts of seawater increases the workload of subsequent oil and seawater separation.
[0004] To address these issues, we offer offshore oil cleanup and recovery equipment. Utility Model Content

The oil adsorption mechanism includes:
[0009] Oil-absorbing sponge, wherein the oil-absorbing sponge uses a porous sponge as a base, and an organosilicon hydrophobic layer is formed on the surface of the sponge through soaking and curing, thereby changing the sponge from its original water-absorbing and oil-absorbing to hydrophobic and oil-absorbing;
[0010] The oil adsorption mechanism also includes multiple telescopic hydraulic rods, with a tension sensor connected to the lower end of each telescopic hydraulic rod.

[0021] (iii) Beneficial effects:
[0022] Compared with existing technologies, this offshore oil cleanup and recovery device has the following advantages:
[0023] I. This marine oil cleaning and recovery device, equipped with an oil adsorption mechanism, uses a telescopic hydraulic rod to immerse an oil-absorbing sponge in the sea surface, which can quickly adsorb oil on the sea surface. An oil discharge mechanism is also included, which uses a squeezing method to expel the oil from the oil-absorbing sponge. The oil is collected in a collection frame through an inclined panel. This device can clean and recover oil from the sea surface. The oil-absorbing sponge has good adsorption properties for oil and can accurately adsorb oil in complex marine environments, while adsorbing relatively less seawater. Compared with the traditional method of using pipes to extract oil from the sea surface, it not only has high oil recovery efficiency but also effectively reduces the workload of subsequent oil and seawater separation.
[0024] II. This offshore oil cleaning and recovery device is equipped with an oil pump and an oil centrifugal separator. When the oil pump is started, it pumps the oil in the collection frame into the oil centrifugal separator, which can separate the oil from the possible small amount of seawater.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0034] The telescopic hydraulic rod 4 in this utility model is a common hydraulic device in the prior art, and this application will not elaborate on its model or internal structure.
[0035] like Figure 1-6 As shown, this utility model provides a technical solution: an offshore oil cleaning and recovery device, including a base plate 1. An oil adsorption mechanism is installed within the base plate 1. The oil adsorption mechanism includes an oil-absorbing sponge 3, which uses a porous sponge as its matrix. Through soaking and curing, an organosilicon hydrophobic layer is formed on the surface of the sponge, thus changing the sponge from its original water-absorbing and oil-absorbing properties to hydrophobic and oil-absorbing properties. Therefore, the oil-absorbing sponge 3 will only absorb oil and not seawater, thereby improving the quality of oil recovery. The oil-absorbing sponge 3 is located at the lower end of the base plate 1. The oil adsorption mechanism also includes multiple telescopic hydraulic rods 4, which are connected to the base plate. Inside the base plate 1, a hydraulic oil tank and a pressurization device are connected to the upper end of the base plate 1. The pressurization device is connected to the telescopic hydraulic rod 4 and is used to control the extension and retraction of the telescopic hydraulic rod 4. A tension sensor 5 is connected to the lower end of the telescopic hydraulic rod 4. The oil adsorption mechanism also includes a mounting plate 12, which is adhered to the upper end of the oil-absorbing sponge 3. Both the upper end of the mounting plate 12 and the lower end of the tension sensor 5 are connected to a connecting plate. The connecting plates of the two are connected by bolts. Through the connection between the mounting plate 12 and the tension sensor 5, the telescopic hydraulic rod 4 can drive the oil-absorbing sponge 3 to move. The tension sensor 5 is used to detect the weight of the oil-absorbing sponge 3.
[0036] The base plate 1 is connected to vertical plates 2 on both sides, and an oil drainage mechanism is connected between the vertical plates 2. The oil drainage mechanism includes a bidirectional threaded rod 6, with threaded grooves at both ends of the bidirectional threaded rod 6. The thread directions of the two threaded grooves are opposite. A drive motor 7 is connected to the side end of the bidirectional threaded rod 6. The oil drainage mechanism also includes a support plate 13, which is connected between the vertical plates 2. The bidirectional threaded rod 6 is rotatably connected inside the support plate 13. The drive motor 7 is connected to the side end of the support plate 13. The support plate 13 is used to support the bidirectional threaded rod 6 and the drive motor 7. The oil drainage mechanism also includes two movable plates 8, which are located at the lower end of the oil-absorbing sponge 3. Water-blocking strips are connected to both sides of the upper end of the movable plates 8. The water strip is used to prevent oil from flowing out from both sides of the moving plate 8. Moving pipes 9 are connected to both sides of the moving plate 8. The moving pipes 9 are threaded to the outer end of the bidirectional threaded rod 6. Starting the drive motor 7 will drive the bidirectional threaded rod 6 to rotate. The rotation of the bidirectional threaded rod 6 and the action of the moving pipes 9 will drive the moving plate 8 to move, which can connect and separate the two moving plates 8. Both the bidirectional threaded rod 6 and the moving plate 8 are set at an inclination, so that the oil can flow along the moving plate 8. The lower end of the moving plate 8 at the lower end is provided with an inclined plate 10. The lower end of the inclined plate 10 is connected to a collection frame 11. The bottom plate of the collection frame 11 is set at an inclination, so as to facilitate the collection of oil at the lowest point of the collection frame 11.
[0037] The base plate 1 is connected to an oil pump 14 and an oil centrifugal separator 15. The oil centrifugal separator 15 is a key device used in the petroleum industry to separate oil, water and solid impurities. It uses the strong centrifugal force generated by the high-speed rotation of the centrifuge rotor to move the denser substances such as water and sediment in the oil to the bottom of the centrifuge tube, while the less dense oil is located in the upper layer, thereby achieving the separation of oil, water and solid impurities. The extraction head of the oil pump 14 is located at the lowest point of the collection frame 11, and its discharge head is connected to the oil centrifugal separator 15 through a pipe. The oil centrifugal separator 15 is equipped with a drain pipe and an oil discharge pipe on its side. When the oil pump 14 is started, it will extract the oil in the collection frame 11 through the extraction head and inject the oil into the oil centrifugal separator 15 for oil and seawater separation. The separated seawater will be discharged into the sea through the drain pipe.
[0038] A protective cover 16 is connected to the upper end of the base plate 1. A battery and a controller are installed inside the protective cover 16. Floating chambers 17 are connected to both sides of the base plate 1. The floating chambers 17 are used to provide buoyancy so that the device can float on the water surface. A propeller is installed at the rear end of the floating chamber 17 to move the device. Oil storage tanks 18 are connected to both sides of the base plate 1. The oil discharge pipe of the petroleum centrifugal separator 15 is connected to the oil storage tank 18 through a pipe. The oil separated from the petroleum centrifugal separator 15 will enter the oil storage tank 18 through the oil discharge pipe.
[0039] Working principle: The device is moved to an oil-containing sea surface area, with both movable plates 8 positioned at either end. The telescopic hydraulic rod 4 lowers the oil-absorbing sponge 3, immersing it in the sea surface. Due to its inherent properties, the sponge quickly absorbs the oil. After absorbing a certain weight of oil, the telescopic hydraulic rod 4 raises the sponge 3 to its highest point. Then, the drive motor 7 starts, rotating the bidirectional threaded rod 6 to move the two movable plates 8 to the lower end of the oil-absorbing sponge 3, connecting the two plates. Finally, the telescopic hydraulic rod 4 slowly presses down. The oil-absorbing sponge 3 is made to act against the moving plate 8, thereby squeezing the oil-absorbing sponge 3 and squeezing out the oil absorbed inside. The discharged oil will flow along the moving plate 8 and then flow into the collection frame 11 through the inclined plate 10. The oil pump 14 is started to extract the oil in the collection frame 11 with the extraction head and inject the oil into the oil centrifugal separator 15 for oil and seawater separation. The separated seawater will be discharged into the sea through the drain pipe, and the separated oil will enter the oil storage tank 18 through the oil drain pipe. The squeezed oil-absorbing sponge 3 can be reused.
