Description

Technical Field

[0001] This invention relates to the field of marine oil spill collection technology, and more particularly to a marine oil spill cleanup device. Background Technology

[0002] Oil is less dense than seawater. Driven by sea winds and waves, oil spills drift and spread, undergoing weathering processes such as evaporation, emulsification, dissolution, and sedimentation. This causes the spill's destructive area to expand rapidly, posing a serious threat to marine industries. Therefore, oil spills must be dealt with promptly. Currently, oil spill collection devices are commonly used to collect oil from the sea surface. However, these devices are not always thorough, leaving a significant amount of oil residue on the surface even after collection.

[0003] A marine oil spill collection device, disclosed in patent document CN104895030B, includes a float with an oil passage trough in the middle. A sliding rod is located at the front end of the oil passage trough, and a slider is slidably connected to the sliding rod. An oil suction pump and an oil storage tank are mounted on the float. A flexible oil suction pipe is mounted on the oil suction pump, with its front end installed on the slider. A secondary oil suction mechanism is installed behind the sliding rod within the oil passage trough. This mechanism includes a conveyor belt, a driving pulley, a driven pulley, and a tension pulley. An oil suction belt is connected to the outer surface of the conveyor belt. The conveyor belt between the driven pulley and the tension pulley is positioned close to the sea surface. A compression wheel and a support pulley are positioned opposite each other between the tension pulley and the driving pulley. The support pulley is connected to the inner surface of the conveyor belt. The compression wheel abuts against the outer surface of the oil suction belt, and an oil collection trough is located below the compression wheel. However, this patent still has some shortcomings: the oil suction pipe easily sucks a large amount of seawater into the oil storage tank during oil suction, causing seawater to occupy space within the oil storage tank. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to solve the problem that when the oil suction pipe is sucking oil, a large amount of seawater is easily sucked into the oil storage tank, resulting in seawater occupying the space inside the oil storage tank, the present invention provides a marine oil spill cleanup device to solve the above problem.

[0005] The technical solution adopted by this invention to solve its technical problem is: a marine oil spill cleanup device, including a pontoon, the pontoon being fixed to the front end of a work vessel, a liquid collection port being fixed to the front end of the pontoon, and liquid collection mechanisms installed on both sides of the liquid collection port, the liquid collection mechanisms being used to push the liquid outside the liquid collection port into the liquid collection port; an oil separation mechanism is provided in the middle section of the pontoon, the oil separation mechanism including an inclined conveyor belt, an oil-water channel being formed below the conveyor belt, the surface of the conveyor belt being covered with absorbent cotton, and a liquid separation mechanism being provided inside the pontoon near the upper end of the conveyor belt. A liquid baffle is fixed, with its lower edge slidably connected to the absorbent cotton. A pressure plate is also fixed inside the float near the lower end of the conveyor belt, used to squeeze the lower end of the conveyor belt. Multiple oil suction ports are fixed on the upper part of the float, each containing an oil suction pipe. A liquid distribution box is located at the tail end of the float, with a filter screen fixed on the top and an oil-water separating membrane fixed on the bottom. A drain pipe is fixed below the oil-water separating membrane, and the bottom of the liquid distribution box is connected to the outside of the float via the drain pipe.

[0006] Preferably, the liquid collection mechanism includes a support, a main shaft, and multiple blades. The support is fixed on both sides of the liquid collection port, the main shaft is vertically rotatably mounted on the support, and the multiple blades are evenly distributed on the main shaft. The main shaft is driven to rotate by a motor.

[0007] Preferably, an inclined trough and a scraper are fixed below the conveyor belt. The scraper is slidably installed in the trough, and the bottom of the scraper is fixedly connected to the trough by a spring. One edge of the scraper abuts against the conveyor belt from a position below the upper end of the conveyor belt. The scraper is used to scrape out the liquid from the absorbent cotton.

[0008] Preferably, a filtrate tank is fixed to the tail end of the plate groove, and a filter screen is fixed to the bottom of the filtrate tank, so that the liquid scraped out of the absorbent cotton can flow into the filtrate tank from the scraper and the upper surface of the plate groove.

[0009] Preferably, the opening of the liquid separator gradually narrows and a liquid separation channel with a width smaller than the opening is formed at the tail of the liquid separator. The opening of the liquid separator is set towards the oil-water channel at the bottom of the conveyor belt. The height of the top of the liquid separation channel is lower than the height of the bottom of the plate trough. The filter screen is fixed at the top of the liquid separation channel, and the oil-water separating membrane is fixed at the bottom of the liquid separation channel.

[0010] Preferably, a partition plate is also fixed inside the float box. The partition plate is positioned above the opening of the liquid separator. The float box, partition plate, and liquid separator together form an oil tank. An oil suction pipe is provided at the top of the oil tank, and a drain pipe is fixed at the bottom of the oil tank. An oil-water separating membrane is fixed at the inlet of the drain pipe.

[0011] Preferably, sealing strips are fixed on both sides of the upper surface of the conveyor belt, and the edges of the conveyor belt are inserted into the sealing strips and slidably connected with the sealing strips.

[0012] The beneficial effect of this invention is that it is equipped with an oil separation mechanism. Through the oil separation mechanism, the oil spill in the pontoon is separated from a large amount of seawater, and then the oil spill in the upper layer is sucked up and stored in a concentrated manner. There is no need to store seawater and oil spill together, which avoids seawater occupying the space in the oil storage tank and improves the efficiency of oil spill collection.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] like Figures 1 to 6 As shown, the present invention provides an embodiment of a marine oil spill cleanup device, including a pontoon 1, which is fixed to the front end of the work vessel. A liquid collection port 2 is fixed to the front end of the pontoon 1, and liquid collection mechanisms 3 are installed on both sides of the liquid collection port 2. The liquid collection mechanisms 3 are used to push the liquid outside the liquid collection port 2 into the liquid collection port 2.

[0024] The liquid collection mechanism 3 includes a support 13, a main shaft 14 and multiple blades 15. The support 13 is fixed on both sides of the liquid collection port 2. The main shaft 14 is vertically rotatably mounted on the support 13. Multiple blades 15 are evenly distributed on the main shaft 14. The main shaft 14 is driven to rotate by a motor.

[0025] When collecting oil spills on the sea surface, the work vessel propels the pontoon 1 forward on the sea surface. The bottom of the pontoon 1 sinks underwater, while the upper part of the pontoon 1 is exposed above the sea surface. The main shafts 14 on both sides of the collection port 2 drive the blades 15 to rotate, pushing the oil spill outside the collection port 2 and the seawater into the collection port 2. This allows the oil spill and seawater to continuously enter the pontoon 1 from the collection port 2, achieving the initial collection effect of marine oil spills.

[0026] The middle section of the pontoon 1 is equipped with an oil-separating mechanism 4, which includes an inclined conveyor belt 5. Sealing strips 21 are fixed to both sides of the upper surface of the conveyor belt 5. The edges of the conveyor belt 5 are inserted into and slidably connected to the sealing strips 21. An oil-water channel is formed below the conveyor belt 5. After the spilled oil and seawater enter the pontoon 1, the seawater is at the bottom of the pontoon 1, and the spilled oil floats above the seawater. Subsequently, most of the spilled oil and a small amount of seawater at the top are pushed to the upper surface of the conveyor belt 5 by subsequent liquid entering the pontoon 1, while most of the seawater and a small amount of spilled oil at the bottom enter the oil-water channel, thus achieving the separation of oil and water. The initial separation of oil spill and seawater in the float box 1 is achieved. At the same time, due to the inclined setting of the conveyor belt 5, when the oil spill and a small amount of seawater are above the conveyor belt 5, the oil spill can float near the upper end of the conveyor belt 5, while the seawater sinks to the bottom near the lower end of the conveyor belt 5. In addition, sealing strips 21 are set on both sides of the conveyor belt 5 to separate the oil spill on the upper surface of the conveyor belt 5 and prevent the oil spill from leaking to the lower part of the conveyor belt 5. Multiple oil suction ports are also fixed on the upper part of the float box 1, and oil suction pipes 8 are set in the oil suction ports. At this time, the oil suction pipes 8 are set at the upper end of the conveyor belt 5 to ensure that the oil suction pipes 8 can only suck up the oil spill.

[0027] The surface of the conveyor belt 5 is covered with absorbent cotton. A baffle plate 6 is fixed inside the float box 1 near the upper end of the conveyor belt 5. The lower edge of the baffle plate 6 is slidably connected to the absorbent cotton. A pressing plate 7 is also fixed inside the float box 1 near the lower end of the conveyor belt 5. The pressing plate 7 is used to squeeze the lower end of the conveyor belt 5.

[0028] As the conveyor belt 5 moves, the absorbent cotton moves along the bottom of the oil spill above the conveyor belt 5. The absorbent cotton absorbs and carries away a small amount of seawater from the bottom of the oil spill. After passing through the oil-water channel below the conveyor belt 5, the absorbent cotton moves to the baffle plate 6 at the lower end of the conveyor belt 5. After the absorbent cotton is saturated, it moves to the baffle plate 6, where the baffle plate 6 squeezes out a small amount of seawater and oil spill from the absorbent cotton, allowing the absorbent cotton to absorb liquid again. The absorbent cotton, after the seawater is squeezed out, moves back to the bottom of the oil spill to absorb a small amount of seawater from the bottom of the oil spill in the float box 1. This leaves only oil spill above the conveyor belt 5, while the seawater above the conveyor belt 5 is absorbed by the absorbent cotton and then discharged into the oil-water channel below the conveyor belt 5, achieving secondary separation of oil spill and seawater.

[0029] Below the conveyor belt 5, there is also an inclined trough 16 and a scraper 17. The scraper 17 is slidably installed in the trough 16. The bottom of the scraper 17 is fixedly connected to the trough 16 by a spring piece. One side edge of the scraper 17 is pressed against the conveyor belt 5 from the lower part of the upper end of the conveyor belt 5. The scraper 17 is used to scrape out the liquid in the absorbent cotton.

[0030] A filtrate tank 18 is also fixed at the tail end of the plate groove 16. A filter screen is fixed at the bottom of the filtrate tank 18. The liquid scraped out of the absorbent cotton can flow into the filtrate tank 18 from the scraper plate 17 and the upper surface of the plate groove 16.

[0031] After absorbing the seawater and a small amount of oil at the bottom of the oil spill, the absorbent cotton first moves to the scraper 17. The scraper 17 squeezes out the debris, oil, and seawater from the surface of the absorbent cotton. The debris is then sent into the filter tank 18 for collection, while a small amount of oil and seawater passes through the filter screen at the bottom of the filter tank 18 and enters the oil-water channel for recycling.

[0032] A liquid separator 9 is provided at the tail end of the float box 1. A filter screen 10 is fixed at the top of the liquid separator 9. An oil-water separating membrane 11 is fixed at the bottom of the liquid separator 9. A drain pipe 12 is fixed below the oil-water separating membrane 11. The bottom of the liquid separator 9 is connected to the outside of the float box 1 through the drain pipe 12.

[0033] The opening of the separator box 9 gradually narrows and a separator channel 19 with a width smaller than the opening is formed at the tail of the separator box 9. The opening of the separator box 9 is set towards the oil-water channel at the bottom of the conveyor belt 5. The height of the top of the separator channel 19 is lower than the height of the bottom of the plate trough 16. The filter screen 10 is fixed at the top of the separator channel 19, and the oil-water separating membrane 11 is fixed at the bottom of the separator channel 19.

[0034] After the seawater and spilled oil in the oil-water channel enter the separator box 9, the pressure inside the separator box 9 gradually increases as the separator channel 19 inside the separator box 9 gradually narrows. The spilled oil is located in the upper layer and the seawater is located in the lower layer. At this time, the seawater in the lower layer can pass through the oil-water barrier membrane 11 under the action of gravity and pressure, and finally be discharged from the float box 1 through the drain pipe 12. The spilled oil in the separator box 9 is discharged into the float box 1 through the filter screen 10 above.

[0035] A partition plate 20 is also fixed inside the float box 1. The partition plate 20 is positioned above the opening of the liquid separator 9. The float box 1, the partition plate 20, and the liquid separator 9 enclose each other to form an oil tank. An oil suction pipe 8 is provided at the top of the oil tank, and a drain pipe is fixed at the bottom of the oil tank. An oil-water separating membrane 11 is fixed at the inlet of the drain pipe.

[0036] The overflowing oil in the separator 9 is discharged into the oil tank through the filter screen 10. The overflowing oil in the oil tank is then sucked out through the suction pipe 8 for centralized treatment. If seawater accidentally enters the oil tank through the filter screen 10, it will sink to the bottom of the oil tank and pass through the oil-water barrier membrane 11 set at the bottom of the oil tank, and finally be discharged through the drain pipe.
