Electromagnetic adsorption type jacket column organism cleaning device

Abstract

The invention discloses an electromagnetic adsorption type jacket column organism cleaning device. The device is characterized by comprises an electromagnet adsorption mechanism, a water pump jet movement adjusting mechanism, a high-pressure water jet mechanism and a controller, wherein the electromagnet adsorption mechanism comprises at least three electromagnetic adsorption plates which are hinged in sequence along the circumferential direction of a jacket column; the water pump jet movement adjusting mechanism comprises a shell; one surface of the shell is fixedly arranged on the middle electromagnet adsorption plate; high-pressure water orifices are respectively arranged on the other five surfaces of the shell; the high-pressure water jet mechanism comprises a high-pressure nozzle which is arranged at the lower end of the shell; and the controller is connected with each of the electromagnet adsorption mechanism, the water pump jet movement adjusting mechanism and the high-pressurewater jet mechanism. According to the cleaning device, stable and accurate cleaning operations at different positions of large ranges of complex sea conditions are realized, and the cleaning efficiency is remarkably improved.

Description

technical field [0001] The invention belongs to the technical field of marine organism cleaning on offshore oil drilling platforms, and in particular relates to an electromagnetic adsorption type jacket column biological cleaning device. Background technique [0002] As an important equipment for offshore oil, drilling and production platforms have been widely used in various sea areas across the country. As the service life increases, the platform needs regular and irregular safety inspections and maintenance, including the detection of platform corrosion. During the operation of the drilling and production platform, a large number of marine organisms will be adsorbed on the jacket columns in the seawater immersion area and tidal range area. The attached marine organisms will intensify the corrosion of the drilling and production platform by the marine environment, and at the same time make the conduit wall smooth. The performance is reduced, which increases the average dr...

Problems solved by technology

[0003] At present, the fixing method of the cleaning robot mechanism is mainly clamper fixing. The clamper is fixed through a mechanical structure to make it have a certain grasping force on the truss, but the outer dimension of the clamper is affected by the outer diameter of the truss steel. Size matters more

The average outer diameter of the conduit of the jacket column platform is 2000mm, resulting in too large a manipulator that meets the requirements or a small clamping force, which is not suitable for use in cleaning robots

In addition, at this stage, the cleaning robot mainly crawls along the pipe wall of the jacket column to control the cleaning range. This movement method is inefficient and has a cleaning blind area, especially when it encounters the joints of the jacket column pipe, it is difficult to adjust the posture. Seriously affected the cleaning effect
