The inner tower barrel matching ring structure is strong in sealing performance and stable in operation, and can effectively isolate seawater infiltration between the tower barrel and the inner tower; the seawater in the gap is pumped out through the drainage pump, the hydrostatic pressure can be reduced, and certain net buoyancy is generated, so that the vertical load borne by the mechanical structure is reduced, the working stability is ensured, and the working safety is improved.

Description

Inner rotating tower barrel matching ring structure

Technical Field

The utility model relates to a single point mooring system especially relates to a can take off and be used for sealed matching ring structure on the formula inner tower.

Background

The single-point mooring is that a marine engineering ship is moored on another fixed or floating structure in a single-point mode, and the ship can rotate for 360 degrees around the structure along with the storm flow to form a weathervane effect so as to avoid destructive power brought by the storm. The single point mooring system can be generally divided into an inner tower permanent mooring system and a releasable inner tower mooring system, the releasable inner tower mooring system adopts a releasable tower barrel form, the releasable tower barrel and the floating device are two separate structures, and the connection with a floating device turret cavity is realized through a matching ring, a sealing device, a mechanical locking device and the like.

The existing tower cylinder connection mode mainly transfers mooring load through a lower matching ring and a mechanical locking device, and an upper matching ring does not participate in load transfer and mainly provides a sealing effect. But because the lower matching ring is a large-sized steel casting structure, manufacturing tolerance is inevitable; meanwhile, the load of the tower cylinder is changed greatly under severe sea conditions and when the load changes, certain structural deformation may be generated, so that the pretightening force of the mechanical locking device is changed greatly, and the situations of locking device and sealing failure may occur if the pretightening force of the locking device is not adjusted timely.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an adversion tower section of thick bamboo matching ring constructs to reduce the load that locking device received on the mooring system, improve the sealing reliability of a tower section of thick bamboo and mooring system's job stabilization nature.

Adversion tower section of thick bamboo matching ring structure, including installing the inner ring on a tower section of thick bamboo outer wall to and install in the outer loop of the intracavity wall department of adversion tower, inner ring and outer loop are the toper cyclic annularly, the bottom of outer loop extends to outside the intracavity wall of adversion tower and has extended along adversion tower bottom and have the baffle, the below that the inner ring bottom is located the outer loop bottom and outside extension has lower baffle, the below department that the top surface of lower baffle is located the baffle is equipped with the recess, the sealing washer has been placed in the recess, the sealing washer offsets with the bottom surface of last baffle and seals.

The matching ring structure of the inner rotating tower cylinder of the utility model can separate the inner rotating tower and the tower cylinder in the mooring system of the inner rotating tower to rotate relatively, the tower cylinder is arranged in the rotating tower cavity of the inner rotating tower, the outer wall of the tower cylinder and the inner wall of the rotating tower cavity are respectively provided with the inner ring and the outer ring relatively, simultaneously, the bottoms of the inner ring and the outer ring are respectively provided with the upper baffle and the lower baffle relatively, and a sealing ring is arranged between the upper baffle and the lower baffle; when a tower barrel and an inner tower rotate relatively, the inner ring and the lower partition plate on the inner ring rotate relatively as well as the outer ring and the upper partition plate on the outer ring, and the sealing ring always abuts against the upper partition plate and the lower partition plate tightly in the rotating process, so that the sealing performance between the inner tower and the tower barrel is ensured, and the seawater sealing is realized. The inner tower barrel matching ring structure is strong in sealing performance and stable in operation, and can effectively isolate seawater infiltration between the tower barrel and the inner tower; then the sea water in the clearance is taken out through the drain pump, can reduce hydrostatic pressure and produce certain net buoyancy to reduce the vertical load that mechanical structure received, guarantee job stabilization nature and improve work safety nature.
