Description

Technical Field

[0002] Offshore platforms operate in extreme corrosive environments characterized by high salinity, high humidity, ultraviolet radiation, microbial erosion, and alternating wet and dry conditions. Corrosion protection of their steel structures is crucial for ensuring platform safety and extending service life. Currently, corrosion maintenance of offshore platforms primarily relies on manual or semi-mechanized methods, typically including scaffolding erection, manual or small-scale mechanical rust removal, cleaning, and painting. This approach has significant drawbacks; therefore, there is an urgent need for automated, intelligent, high-quality, environmentally friendly, and long-lasting corrosion protection equipment suitable for marine environments.

[0003] Currently, among existing construction equipment, such as the patent with publication number CN215695142U, this application provides a construction platform for anti-corrosion coating of the inner wall of steel pipes, belonging to the field of construction equipment technology. This anti-corrosion coating construction platform for the inner wall of steel pipes includes a base and a coating mechanism. A spiral tube is rotatably mounted on the top of the base, and a stud is installed on the internal thread of the spiral tube.

[0004] It has been found in the use of existing equipment that it typically has limited functionality, which increases the complexity of manual operation and reduces the efficiency of anti-corrosion work. Summary of the Invention

The drying device is mounted on the base. The spray pipes are installed on the outer wall of the base; Multiple sets of first nozzles are connected and installed on the spray pipe; Multiple sets of first valves are respectively connected and installed on multiple sets of first nozzles; The first cover is installed on the outer wall of the base.

The second nozzle is mounted on the base via an adjustment device; The vehicle body is equipped with a collection device and a supply device. The collection device is connected to the first cover, and the supply device is connected to the spray pipe and the second nozzle. When anti-corrosion treatment is required on the platform, the platform is first ground and rust is removed using a grinding component. The rust debris is collected by the collection device. Then, the spray pipe is directed towards the platform, and the anti-corrosion coating is supplied through the supply device. Multiple sets of first nozzles then spray the anti-corrosion coating onto the ground area to achieve anti-corrosion treatment. After the anti-corrosion coating is applied, the base is rotated so that the drying device faces the sprayed area.
