[0001] The utility model relates to the field of offshore oil spill processing equipment, in particular to an offshore oil spill self-propelled oil skimmer. Background Art

[0002] Marine oil spill pollution refers to the pollution caused by the leakage of petroleum and its refined products during the process of mining, storage, transportation, etc. Marine ship oil spill accidents and offshore oil field blowouts are one of the main causes of marine environmental pollution damage. Due to the particularity of the marine environment and oil spills, oil spills will have direct or indirect impacts on marine ecology, tourism, aquaculture and many other aspects.

[0003] At present, most of the existing oil spill recovery devices use a floating body with an oil-absorbing turntable to absorb the original crude oil on the sea surface, and then scrape the absorbed crude oil off. However, when the turntable works on the sea surface, it will stir the floating oil, accelerate the spread of the floating oil, expand the area of ​​marine pollution, and is not conducive to the recovery of the floating oil.

[0004] Therefore, it is necessary to provide a new offshore oil spill self-propelled oil skimmer to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0025] See also Figures 1 to 4 The embodiment of the utility model provides a self-propelled oil skimmer for offshore oil spills, and the self-propelled oil skimmer for offshore oil spills comprises: a hull 1, an annular oil absorption felt 2, an oil skimmer tank 4 and an oil scraper assembly 5.

[0026] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 The stern of the hull 1 is provided with an installation cavity 1b, and an electric propeller 6 is installed in the installation cavity 1b. The hull 1 is provided with an annular oil absorption felt 2 for oil absorption, and the annular oil absorption felt 2 is tiltedly arranged on the hull 1. Specifically, one end of the annular oil absorption felt 2 is located in the oil inlet opening 1a opened at the front end of the hull 1, and the other end of the annular oil absorption felt 2 extends toward the stern of the hull 1 and tilts upward;

[0027] The hull 1 is provided with a driving assembly 3 for driving the annular oil-absorbing felt 2, and the driving assembly 3 includes a mounting stand 31 and a driven gear column 34. The mounting stand 31 is fixedly mounted on the hull 1, and a rotatably connected active gear column 32 is mounted on the mounting stand 31. A driving motor 33 for driving the active gear column 32 to rotate is mounted on the mounting stand 31. The driven gear column 34 is rotatably mounted in the oil inlet opening 1a opened in the hull 1 through a bracket, and a toothed belt 21 is fixedly embedded on the inner felt surface of the annular oil-absorbing felt 2, and the toothed belt 21 is meshed with the active gear column 32 and the driven gear column 34 respectively.

[0028] It should be noted that: turning on the electric propeller 6 can drive the hull 1 to sail on the sea, and the head of the hull 1 is provided with an oil inlet opening 1a, so that the oil can be gathered into the oil inlet opening 1a during sailing, so that the annular oil absorption felt 2 inserted into the underwater part can absorb the oil. At this time, turning on the driving motor 33 can drive the active gear column 32 to rotate, so that the annular oil absorption felt 2 is transmitted, so that the hull 1 can sail while inserting different parts of the annular oil absorption felt 2 under the sea surface to absorb the oil.

[0029] In the embodiments of the present invention, please refer to Figure 1 and Figure 4 The hull 1 is also fixedly mounted with an oil collecting tank 4, which is a convex structure, and an oil inlet 4a is provided on the convex surface of the oil collecting tank 4, and the oil inlet 4a is located below the upper inclined end of the annular oil absorbing felt 2;

[0030] An oil scraper assembly 5 for scraping oil from the annular oil-absorbing felt 2 is installed in the oil collecting box 4. Specifically, the oil scraper assembly 5 is located at the oil inlet 4a of the oil collecting box 4, and the oil scraper assembly 5 includes an oil scraper plate 51. A rotating shaft 52 is inserted at the bottom of the oil scraper plate 51, and the rotating shaft 52 is rotatably installed in the oil collecting box 4. A spring 53 is installed on the back of the oil scraper plate 51, and the other end of the spring 53 is fixedly engaged with an abutment plate 54, and the abutment plate 54 is fixedly engaged on the inner box wall of the oil collecting box 4. The oil scraper plate 51 is inclined, and the top plate surface of the oil scraper plate 51 abuts against the lower felt surface of the annular oil-absorbing felt 2.

[0031] It should be noted that: after the annular oil absorption felt 2 absorbs the oil, its felt surface rotates to the oil inlet 4a, the oil scraper 51 can scrape off the oil on the annular oil absorption felt 2 at that location, and the annular oil absorption felt 2 after scraping off the oil continues to rotate to the sea surface at the oil inlet opening 1a, thereby absorbing the oil, so that the oil on the sea can be processed continuously. Since the oil scraper 51 is arranged at an angle, the oil scraped off by the oil scraper 51 can flow along the oil scraper 51 to the oil collection tank 4 for storage;

[0032] A spring 53 is provided on the back of the oil scraper plate 51 , so as to alleviate the rigid contact force between the scraping surface of the oil scraper plate 51 and the annular oil absorbing felt 2 , thereby preventing the oil scraper plate 51 from damaging the annular oil absorbing felt 2 .

[0033] The working principle of the offshore oil spill self-propelled oil skimmer provided by the utility model is as follows:

[0034] The electric propeller 6 can be turned on to drive the hull 1 to sail on the sea surface, and the head of the hull 1 is provided with an oil inlet opening 1a, so that the oil can be gathered into the oil inlet opening 1a during sailing, so that the annular oil absorption felt 2 inserted into the underwater part can absorb the oil. At this time, the driving motor 33 can be turned on to drive the active gear column 32 to rotate, so that the annular oil absorption felt 2 is transmitted, so that the hull 1 can sail while inserting different parts of the annular oil absorption felt 2 under the sea surface to absorb the oil.

[0035] When the annular oil absorbing felt 2 absorbs oil and its felt surface rotates to the oil inlet 4a, the scraper plate 51 can scrape the oil on the annular oil absorbing felt 2 at this location. After scraping off the oil, the annular oil absorbing felt 2 continues to rotate to the sea surface at the oil inlet opening 1a, thereby absorbing the oil. Therefore, the offshore oil can be processed continuously. Since the scraper plate 51 is inclined, the oil scraped off by the scraper plate 51 can flow along the scraper plate 51 to the oil collecting tank 4 for storage. A spring 53 is provided on the back of the scraper plate 51, thereby alleviating the rigid contact force between the scraping surface of the scraper plate 51 and the annular oil absorbing felt 2, thereby preventing the scraper plate 51 from damaging the annular oil absorbing felt 2.

[0036] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0037] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
