Problems solved by technology

However, in the water area where the drilling platform is located, the environmental factors are complex and changeable, and the foundation of the platform is vulnerable to the impact of large underwater undercurrents. There are many, especially the seawater in the sea area is highly corrosive, the amount of microorganisms and suspended mud is large, and the attached microorganisms or molluscs will release certain chemical substances, making the columnar supports inevitably rusted, requiring divers It is time-consuming and labor-intensive to often go underwater to check, and the underwater situation is difficult to monitor, which is likely to bring safety hazards
Furthermore, in deep waters, the drilling platform needs to be raised and lowered reasonably according to the change of water depth, and the support is an important supporting part and track for the drilling platform to rise and fall independently. When there are too many attachments on the outer wall of the support, it will cause drilling Reduced lifting flexibility of the platform

Abstract

The invention discloses a cleaning device for a columnar supporting part of an above water drilling platform. The cleaning device comprises two clamping units, wherein each clamping unit comprises a traveling cylinder and a track ring, the track rings are fixed to the lower end surfaces of the traveling cylinders, flanges are arranged on the inner circumferential walls of the track rings in the circumferential directions of the track rings, outer tooth belts are installed on the upper end surfaces of the flanges, semicircular inner rings are further arranged below the traveling cylinders, inner tooth belts are arranged on the upper surfaces of the inner rings, and supporting seats are arranged below the track rings; and rotating motors are arranged on the supporting seats, the output endsof the rotating motors extend upwards after penetrating through gaps between the flanges and the inner rings, rotating gears are installed at the tail ends of the extension sections of the output endsof the rotating motors, the rotating gears are correspondingly matched with the outer tooth belts and the inner tooth belts, and cleaning assemblies are arranged on the lower surfaces of the supporting seats. Aiming at the defects in the prior art, the cleaning device can regularly clean attachments of the supporting part immersed in seawater, the damage probability of the supporting part is reduced, and the service life of the drilling platform is further improved.

Description

technical field [0001] The invention relates to the fields of basic engineering drilling, petroleum engineering drilling and the like, and in particular relates to a cleaning device for a columnar support of a water drilling platform. Background technique [0002] At present, more than 100 countries and regions in the world are conducting oil and gas exploration offshore, and more than 40 countries and regions are exploiting more than 150 offshore oil and gas fields. 25% of the total volume, while drilling or drilling platforms are widely used in offshore oil and gas exploitation; at the same time, both in the field of geological exploration and in the construction of bridges, towers and other lines, it is necessary to drill the waters of the passage. In order to carry out pile foundation construction, a drilling platform is also required. The drilling platform is a professional operating platform mainly used for drilling in water areas. However, in the water area where the...
