[0031] The utility model provides a marine organism cleaning device for a seawater lifting pump tower of an offshore platform, such as Figure 1-4 As shown, the device comprises: an L-shaped bracket 1, a scraper assembly 2, a first supporting mechanism 3, and a second supporting mechanism 4;

[0032] The L-shaped bracket 1 is used to provide a bearing platform for the first supporting mechanism 3 and the second supporting mechanism 4;

[0033] The scraper group 2 is tangent to the offshore platform seawater lifting pump tower and is used to remove marine organisms attached to the offshore platform seawater lifting pump tower when the offshore platform seawater lifting pump tower is raised or lowered;

[0034] One end of the first supporting mechanism 3 is arranged on the vertical plane of the L-shaped bracket 1, and the other end is connected to the first side surface of the scraper group 2, and is used to adjust the tangential position relationship between the scraper group 2 and the seawater lifting pump tower of the offshore platform in the horizontal direction; and is also used to rotate along the vertical direction to adjust the tangential position relationship between the scraper group 2 and the seawater lifting pump tower of the offshore platform;

[0035] One end of the second supporting mechanism 4 is disposed on a horizontal plane of the L-shaped bracket 1 , and the other end is connected to the second side surface of the scraper assembly 2 , so as to provide a vertical traction force to the scraper assembly 2 .

[0036] During the maintenance of the offshore platform seawater lifting pump tower, the offshore platform seawater lifting pump tower needs to be lifted and lowered. During this process, the scraper group 2 of the utility model maintains a tangential relationship with the offshore platform seawater lifting pump tower under the action of the first supporting mechanism 3 and the second supporting mechanism 4, and cleans the attached marine organisms during the lifting and lowering operations, which is efficient and fast, and reduces labor costs and maintenance time.

[0037] The scraper assembly 2 includes at least two scrapers 21 and a blade holder 22;

[0038] The at least two scrapers 21 are arranged obliquely, and the cutting surfaces are inclined;

[0039] The at least two scrapers 21 are arranged on a blade holder 22;

[0040] The first side surface of the tool holder 22 is connected to the first supporting mechanism 3 , and the second side surface is connected to the second supporting mechanism 4 .

[0041] Regardless of whether the offshore platform seawater lifting pump tower is raised or lowered, all the scrapers 21 of the scraper group 2 are inclined so that the cutting surfaces of all the scrapers 21 can be inclined and always tangent to the offshore platform seawater lifting pump tower, so that the attached marine organisms can be cleaned.

[0042] The first side surface of the tool holder 22 is perpendicular to the second side surface.

[0043] Exemplarily, the vertical surface of the tool holder 22 is connected to the first support mechanism 3, and the horizontal surface of the bottom is connected to the second support mechanism 4, so that the first support mechanism 3 and the second support mechanism 4 respectively support the scraper assembly 2 from different directions.

[0044] The first supporting mechanism 3 includes a distance adjusting rod 31, a rotating shaft frame 32, and a rotating shaft 33. One end of the distance adjusting rod 31 is connected to the first side surface of the scraper group 2, and the other end is connected to the rotating shaft frame 32. The rotating shaft frame 32 is hinged to the vertical surface of the L-shaped bracket 1 through the rotating shaft 33.

[0048] The second supporting mechanism 4 further includes a limit block 45 . At least two limit blocks 45 are provided and are located on both sides of the bearing seat 41 , and are used to abut against the scraper assembly 2 moved to the lowest point.

[0049] During the lifting process of the offshore platform seawater lifting pump tower, the base of the scraper group 2 is fixed to the deck surface, the scraper group 2 fits the cylindrical surface, and the friction force is always tangential to the movement direction of the offshore platform seawater lifting pump tower, thereby cleaning the attached marine organisms.

[0050] During the descent of the offshore platform seawater lifting pump tower, under the limit of the limit block 45, the scraper group 2 moves downward under the restriction of the first support mechanism 3. After moving to the lowest point, the friction force is tangent to the offshore platform seawater lifting pump tower, thereby cleaning the attached marine organisms.

[0051] Furthermore, the device also includes a cleaning mechanism 6, which is arranged on a vertical plane and is used for spraying and cleaning the seawater lifting pump tower of the offshore platform.
