Abstract

The invention belongs to the field of ocean platform structures and relates to a settleable ocean platform which comprises winding shafts, a groove, well drilling equipment, a convex block, a ship, a left cover plate, a right cover plate, ballast compartments, motors, speed reducing boxes, gears, ballast pumps and an integrated control line. The ocean platform is formed by the ship and the cover plates, the cover plates are mounted outside the ship in a sleeved manner through the winding shaft and include the left cover plate and the right cover plate, the winding shafts transversely penetrate the whole ship, the motors are fixed on the left side and the right side of the ship and drive the winding shafts with the gears to rotate, the groove is arranged on the upper surface of the left cover plate, the convex block is arranged on the right cover plate, the well drilling equipment of various kinds is mounted on the upper surface of the ship, the ballast compartments are arranged in the ship, and pump and drain water through the ballast pumps, and both the ballast pumps and the motors are controlled by the integrated control line which penetrates an outer plate of the ship to be connected at a control end on the water. Consequently, by the settleable ocean platform, the problem that a conventional fixed ocean platform is unadjustable in height and cannot submerge in the water to resist strong wind and big waves is solved.

Description

Can decanter type platform

Technical field

The present invention relates to can decanter type platform, belongs to offshore platform structure field.

Background technology

Along with China's economy grows continuously and fast, hydrocarbon resources is under-supply will become the principal contradiction that hinders economic development, for improving the occupancy volume of hydrocarbon resources, the exploitation of marine oil and gas has become the strategic emphasis that China realizes energy sustainable development, accelerate domestic oil-gas exploration and development and make full use of domestic and international two kinds of resources, two markets guarantee that the safety and stability supply of oil gas has become the state basic policy of China, offshore oil drilling platform is that drill outfit bases oneself upon marine basis, current domestic main employing jacket-type, bottom-sitting type, the fixed platforms such as single column platform, fixed platform in use exists the not liftable problem of platform, when platform at the incoming tide apart from the water surface too during nearly waviness tidewater can be splashed into platform, platform is apart from the too high waste work-hours of the water surface at ebb tide, and sea level rise along with ice cube thawing in Global Greenhouse Effect climate warming the two poles of the earth causes, the platform of if things go on like this building for many years cannot normally be worked, although developed mechanical type lifting platform, but because platform is too huge, liftable scope is really limited, and these platforms all exposed wind wave punchings at one's discretion on surface, sea level when wind and waves, being subject to horizontal shear force crosses ambassador's platform life span and significantly reduces, the problem existing in order to change these fixed platforms, need to develop a can the anti-wave of submerged wind resistance, podium level can regulate, on the long-term equal altitudes of platform energy is bubbled through the water column, the Novel ocean platform that structural safety is stable.

Summary of the invention

The object of this invention is to provide can decanter type platform.

The problem to be solved in the present invention is not liftable of traditional fixed offshore platform height, problem that can not the anti-wave of submerged wind resistance during wind and waves.

For realizing object of the present invention, the technical solution used in the present invention is:

Can decanter type platform, comprise twisted axis, groove, drill outfit, drilling well deck, projection, hull, packing seal, left cover, right cover plate, ballast tank, motor, drop-gear box, gear, ballast pump and integrated control line, described platform is comprised of hull and cover plate, hull is by the Q235 steel enclosed construction that is welded, cover plate is divided into left cover and right cover plate two parts, left cover and right cover plate are 1/4th globositys, left cover and right cover plate are all sleeved on hull outside by twisted axis, twisted axis laterally runs through whole hull, on each twisted axis, are furnished with two sleeve gears, motor is fixed on the left and right sides in hull, motor output end is provided with drop-gear box, motor by drop-gear box after driven gear rotate, left cover upper surface surrounding is provided with groove, right cover plate upper surface is provided with projection, when left cover and right cover plate close up, groove and projection are meshed, the upper surface of hull is drilling well deck, various drill outfits have been installed on drilling well deck, when drilling well deck lower surface annular surrounding is lined with packing seal left cover and right cover plate are closed up, all seams are all watertight structure and guarantee in cabin water-tight, in hull, all arranged ballast tank all around, ballast tank is by ballast pump water-pumping/draining, ballast pump is contained in the middle left and right sides of hull, ballast pump and motor are all controlled by integrated control line, integrated control line makes device settling process Long-distance Control through the control end of receiving on the water surface after the outside plate of hull.

Groove domestic demand pad one deck rubber strip; Packing seal is silica gel material; The outside plate interface of twisted axis and hull need be done watertight and process, and the outside plate interface of integrated control line and hull need be done watertight and process.

Advantage of the present invention is: hull formula platform makes drilling well deck the same apart from seawater surface height without random flood tide ebb on bubbling through the water column all the time, operating altitude can utilize ballast pump water-pumping/draining to regulate according to need of work simultaneously, the cover plate that hull is set up outward neither can affect work can play again the anti-wave effect of wind resistance, after cover plate can being closed up when wind and waves, toward ballast tank, constantly draw water and by the anti-wave of designing requirement submerged wind resistance, platform is extended service life in device, cover plate surrounding and seam encapsulation process make can not leak drill outfit in cabin can be by marine corrosion, motor and ballast pump utilize integrated control line can realize Long-distance Control minimizing safety misadventure.
