Problems solved by technology

[0003] The support 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 inside, 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

Abstract

The invention discloses an offshore drilling platform shore rust removing device comprising a drilling platform and a plurality of shores. Electric telescopic rods are installed at the lower end of the drilling platform. Device blocks are fixed to the telescopic ends of the electric telescopic rods and are arranged on the shores in a sleeving mode. The side walls of the device blocks are providedwith device openings. Wave pushing plates are placed in the device openings. Abutting rods are fixed to the rear sides of the wave pushing plates. Cavities are formed in the two sides of the device blocks. The tail ends of the abutting rods extend into the cavities and are fixedly connected with pistons. The pistons divide the cavities into air cavities and paint cavities. The side walls of the pistons and the inner walls of the air cavities are elastically connected through first springs. Annular grooves are formed in the lower ends of the device blocks. Annular folding airbags are installedin the annular grooves. The offshore drilling platform shore rust removing device is reasonable in structure, rust removing operation can be conducted on the shores automatically through sea waves, safety is higher, and rustproof paint can be sprayed automatically.

Description

technical field [0001] The invention relates to the technical field of offshore drilling platforms, in particular to a rust removal device for support columns of 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 support 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 inside, causing serious consequences . At present, it is necessary to manually go down to the bottom of the drilling platform f...
