Problems solved by technology
[0003] The columns of the offshore drilling platform are constantly eroded by seawater because they have been erected in seawater for a long time, and the sea is rough, and the waves are constantly scouring the columns. If it is not cleaned up in time, the rust will slowly 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 a large safety hazard, and rust removal takes a lot of time

The invention relates to the technical field of drilling equipment, and discloses a rust removal device for an offshore drilling platform, which comprises a platform, wherein a stand column is fixedly connected to the bottom of the platform, a supporting tube is fixedly connected to the middle of the stand column, and a one-way valve is arranged at the upper end of the supporting tube. A fan-shaped corrugated tube, a movable cavity and a supporting block are arranged, so that in the stretching and retracting process of the fan-shaped corrugated tube, seawater can be sucked through a water inlet tube and input into a movable cavity through the water outlet tube, the seawater is ejected out of the bottom of the supporting block in the polishing process, the seawater is ejected to the polished position, chloride ions can be decomposed from the seawater, and the seawater has weak acidity, has an activation effect on steel, is convenient to abrade, achieves the purpose of smoothness and increases the astringency; meanwhile, the situation that surface steel of the stand column becomes soft and the hardness of the steel is lost due to a too high temperature during grinding is prevented; in addition, water has a lubricating effect, so that friction between the stand column and a grinding stone is reduced, and therefore, the surface of the stand column is ground to be finer, smoother and more durable, and the grinding effect is improved.
Description
technical field [0001] The invention relates to the technical field of drilling equipment, in particular to a derusting device for an offshore drilling platform. Background technique [0002] Offshore drilling platforms are mainly offshore structures used for drilling wells, equipped with drilling, power, communication, navigation and other equipment, as well as safety lifesaving and personnel living facilities. They are indispensable means for offshore oil and gas exploration and development. Submersible drilling platform. [0003] The columns of the offshore drilling platform are constantly eroded by seawater because they have been erected in seawater for a long time, and the sea is rough, and the waves are constantly scouring the columns. If it is not cleaned up in time, the rust will slowly expand and corrode the interior, causing serious consequences. At present, it is necessary to manually go down to the bottom of the drilling platform to remove the rust, which has gr...
