[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-Figure 3 The utility model provides a technical solution: a floating waterproof casing marine growth removal device for an offshore oil platform, comprising a casing 1, a roller 2, and a float 8. Multiple rollers 2 are fixedly installed on each side of a hexagonal frame 5 by means of bolts 10 and bolt ear seats 9. Baffles 4 are installed at both ends of the rollers 2. The hexagonal frame 5 is divided into multiple layers. Each layer of the hexagonal frame 5 is connected to each other by means of hinges 3 and shackles 7 and embraces the outer wall of the casing 1 to form a three-dimensional cleaning structure. The float 8 is connected to the top of the uppermost hexagonal frame 5 by means of the hinge 3 and the shackle 7. Chain ears 6 are provided at the vertices of each layer of the hexagonal frame 5, and the chain ears 6 are fixedly connected to the hinge 3.

[0022] In some specific embodiments, the number of rollers 2 is six per layer, evenly distributed on each side of the hexagonal frame 5, and the curvature of the roller 2 matches the curvature of the sleeve 1. The matching curvature ensures that the roller 2 can fit closely to the surface of the sleeve 1 during the rolling process, thereby improving the cleaning efficiency, reducing the wear between the roller 2 and the sleeve 1, and extending the service life of the device.

[0023] In some specific implementation schemes, the hexagonal frame 5 is designed to have three layers, with each layer spaced 50 cm apart. The three-layer design can cover a larger area of ​​the casing 1 and improve the cleaning efficiency. The 50 cm interval can adapt to different water depths and tidal changes, ensuring that the roller 2 always maintains contact with the casing 1 and does not lose the cleaning effect due to changes in water depth.

[0024] In some specific embodiments, the baffle 4 is fixed to both ends of the roller 2 by welding or bolting. The baffle 4 is made of stainless steel and is connected by welding or bolting to prevent the roller 2 from falling off or being damaged during rotation.

[0025] In some specific embodiments, the bolts 10 pass through the bolt ears 9 to fix the roller 2 on the hexagonal frame 5, ensuring that the roller 2 can rotate with the hexagonal frame 5 without falling off.

[0026] In some specific implementation schemes, the buoyancy of a single float 8 is greater than 15KG, ensuring that the device can be stably suspended at different water levels. This design can ensure the stability and buoyancy balance of the device in seawater, and the device will not sink due to insufficient buoyancy or float excessively due to excessive buoyancy, affecting the cleaning effect.

[0027] Working principle: During installation, first use hinges 3 to connect three layers of hexagonal frames 5 with intervals of 50 cm, shackles 7, and floats 8 in series, keeping them axially separated. When the tide is high, the float 8 is affected by buoyancy and drives the entire cleaning device to rise; when the tide is low, the float 8 and the cleaning device will drop accordingly. Under the action of the tide, the roller 2 rolls up and down and rotates on the surface of the casing 1, thereby effectively removing marine organisms attached to the casing 1. The material and curvature design of the roller 2 enable it to fit closely to the surface of the casing 1 during rolling, thereby improving the cleaning efficiency. At the same time, the number and distribution of the floats 8 also ensure the stability and buoyancy of the device in water.

[0028] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
