Ocean platform pile leg cleaning device and method

Abstract

The invention discloses an ocean platform pile leg cleaning device and method.The ocean platform pile leg cleaning device comprises a plurality of pile legs, the pile legs are connected into a whole through upper sliding ways, the upper sliding ways are located on the upper portions of the pile legs, each pile leg is provided with a rotating base, the top of each rotating base is provided with a lower sliding way, and the side face of each rotating base is provided with a telescopic mechanical arm; a plurality of cleaners are connected to the upper sliding way in a sliding mode. All the platform pile legs are connected, the two cleaners are used for orderly cleaning the pile legs, operation is easy, all the cleaners do not need to be controlled at the same time, and when the cleaners go wrong, replacement and maintenance are convenient; the cleaner is controlled through the upper track and the lower track, the cleaner can do circular motion around the pile leg during cleaning, cleaning dead corners can be avoided through combination of the upper track and the lower track, and therefore the stability of the ocean platform is guaranteed. The mode of combining the scraping plate and water flow and cavitation bubbles is adopted for cleaning, the scraping plate is firstly adopted for cleaning, then high-energy bubble water cleaning is conducted, and the pile leg can be effectively protected.

Description

technical field [0001] The present invention relates to a device and method for cleaning pile legs, in particular to a device and method for cleaning pile legs of an offshore platform. Background technique [0002] With the continuous development of my country's marine industry, activities such as offshore drilling, oil production, container transportation, observation, navigation, and construction have shifted from shallow seas to deep seas, and the number of offshore platforms has continued to increase. Due to the complex and changeable marine environment, the offshore platform will be eroded from above and below the sea surface. The legs of the offshore platform are the foundation for supporting the platform. If it is continuously impacted and corroded by underwater organisms and seawater, it will cause damage to the marine engineering structure. , that will create a security risk that may ultimately have irreversible consequences. Therefore, there is a need for a device...

Problems solved by technology

[0003]At present, the cleaning of offshore platform legs is divided into manual cleaning and automatic cleaning. Manual cleaning is mainly to carry cleaning equipment into the water for cleaning operations. Big, there are serious security risks

The automatic cleaning adopts a liftable structure, and the cleaning device adopts a single method of brush or scraper, which has a general effect on removing attached crops and rust, and it is difficult to relieve the pressure on the pile legs in an all-round way. For example, the patent CN202110908695.3 uses a cable Lifting and scraper cleaning; in the patent CN202111020834.5, the cleaning device is installed at the bottom, and the scraper is used for cleaning. The cleaning device itself is easy to corrode, and the cleaning method is single
