Wave type rust removing device of offshore drilling platform

Abstract

The invention discloses a wave type rust removing device of an offshore drilling platform. The wave type rust removing device of the offshore drilling platform comprises a drilling platform body and multiple fixing columns. The two sides of the fixing columns are rotationally connected with rotating rods. The tail ends of the rotating rods are fixedly connected with wave blocking plates. An fan-shaped elastic air bag is connected between the upper side of each wave blocking plate and the side wall of the corresponding fixing column. Cylindrical cavities are arranged in the fixing column. The cylindrical cavities communicate with the fan-shaped elastic air bag through an intake tube. A guide pipe is fixedly arranged at the inner bottom of each cylindrical cavity. Each guide pipe communicates with the corresponding cylindrical cavity through an air hole. Each guide pipe is provided with a piston in a sliding sealed manner and sleeved with a reset spring. The upper end of the guide pipe penetrates through a drilling platform body. A valve is installed at a pipe opening of each guide pipe. The outer side wall of each piston is provided with a first annular magnet in an embedded manner.The wave type rust removing device of the offshore drilling platform is reasonable in structure, capable of utilizing the wave to automatically remove rust on the fixing columns, safer and good in rust removal effect.

Description

technical field [0001] The invention relates to the technical field of offshore drilling platforms, in particular to a wave-type derusting device for offshore drilling platforms. Background technique [0002] An offshore drilling platform is an offshore structure mainly used for drilling wells. Top-mounted drilling, power, communication, navigation and other equipment, as well as safety and lifesaving and personnel living facilities. The indispensable means of offshore oil and gas exploration and development mainly include jack-up and semi-submersible drilling platforms. [0003] The fixed column of the offshore drilling platform is eroded by seawater. Even if it is coated with anti-rust paint, rust will still appear on the outer wall after a period of use. If it is not cleaned in time, the rust will gradually expand and corrode the interior, causing serious consequences . At present, it is necessary to manually go down to the bottom of the drilling platform for derusting...

Problems solved by technology

[0003] The fixed column of the offshore drilling platform is eroded by seawater. Even if it is coated with anti-rust paint, rust will still appear on the outer wall after a period of use. If it is not cleaned in time, the rust will gradually expand and corrode the interior, causing serious consequences

At present, it is necessary to manually go down to the bottom of the drilling platform for rust removal, which has great safety hazards, and rust removal takes a lot of time
