Description
Technical field
The invention belongs to ocean engineering underwater performance equipment field, being specifically related to one provides centre of gravity adjustment and buoyancy support for the dynamic cable in deep-sea and accessory kit lifting construction under water thereof.
Background technology
Dynamically in cable work progress, cable generally to be laid prior to hull or electromotor under water.When cable termination and subsea anchor system system are attached, must just float under water for the ease of salvaging and installing.Dynamically cable is limited by bending radius and safe working load, it is necessary to the most stable in water.
Summary of the invention
Goal of the invention: the invention aims to solve deficiency of the prior art, one is provided to meet dynamic cable and accessory kit installation exercise under water thereof, can realize buoyancy aid sedimentation to watertight compartment water filling, the center of gravity realizing buoyancy aid hoisting structure by controlling the water injection rate of each watertight compartment regulates.Weight, by being articulated and connected, when floating block is rocked by environmental load effect, is not affected by the dynamic cable terminal of floating block carrying simultaneously and floating block.So that dynamically cable terminal and the metastable dynamic cable water filling decanter type annular of whole anchoring system under water lift buoyancy aid equipment.
Technical scheme: one of the present invention dynamic cable water filling decanter type annular lifting buoyancy aid equipment, including some watertight compartments being connected with each other and mutually separate, several described watertight compartments are interconnected to form loop configuration, described watertight compartment includes inner skeleton and outer skin, it is respectively equipped with water injection hole on each described watertight compartment, steam vent and osculum, each described watertight compartment connects also by pull bar lifting device, one end of described pull bar is connected with described watertight compartment by latch, and the other end of described pull bar is connected with described lifting device by hanger.
Further, the quantity of described watertight compartment is 4.
Further, described outer skin uses foaming polymer material to make.
Further, described inner skeleton uses metal structure.
Further, described water injection hole and steam vent are arranged on top, and osculum is arranged on bottom.
Further, described lifting device uses 316 rustless steels to make.
Further, described hanger uses 180 ° of rotations in spin direction.
Beneficial effect: the present invention meets dynamically sea cable and the underwater construction operation of accessory kit, compares the design of traditional solid floating block, and the present invention can realize floating block natural buoyancy and quickly adjust, it is simple to construction；Keeping carrying object under water the most stable, the cable or the pipeline that do not connect terminal damage.This ring float structure can meet dynamic cable and accessory kit installation exercise under water thereof, can realize buoyancy aid sedimentation to watertight compartment water filling, and the center of gravity realizing buoyancy aid hoisting structure by controlling the water injection rate of each watertight compartment regulates.Weight, by being articulated and connected, when floating block is rocked by environmental load effect, is not affected by the dynamic cable terminal of floating block carrying simultaneously and floating block.So that dynamically cable terminal and whole anchoring system under water are the most stable.

Detailed description of the invention
A kind of dynamically cable water filling decanter type annular lifting buoyancy aid equipment as shown in Fig. 1 to Fig. 3, the watertight compartment 1 being connected with each other including four and mutually separate, several described watertight compartments 1 are interconnected to form loop configuration, described watertight compartment 1 includes inner skeleton 2 and outer skin 3, it is respectively equipped with water injection hole 4 on each described watertight compartment 1, steam vent 5 and osculum 6, each described watertight compartment 1 connects also by pull bar 8 lifting device 7, one end of described pull bar 8 is connected with described watertight compartment 1 by latch 10, the other end of described pull bar 8 is connected with described lifting device 7 by hanger 9.
For guaranteeing the hydrodynamic performance of dynamic cable and accessory kit thereof, associated components need to be installed to the predetermined suspension depth of water when at sea laying.Water filling decanter type buoyancy aid, structure comprises four watertight compartments, can regulate buoyancy reserve by the way of to each watertight compartment water filling, and then realizes the sedimentation of dynamic cable and hang to the predetermined depth of water.When integral assembling structure barycentre offset is bigger, center-of-gravity regulating distribution can be carried out by regulating the water injection rate of each watertight compartment, it is ensured that the stability of underwater construction operation.
Lifting buoyancy aid generally loop configuration, can effectively guarantee being uniformly distributed of Underwater loading, and buoyancy aid hoisting structure can be avoided to occur beating torsion phenomenon when wave presents the different angle of attack from ocean current.
1, ring float, this part is the main source that buoyancy provides, and comprises outer skin and inner skeleton structure.Eyelid covering material is formed by synthesizing foaming polymer material, and the feature of this material is in addition to low-density, in addition it is also necessary to possess higher mechanical strength, low water absorption rate.Skeleton is metal structure, it can be ensured that the hot strength in hoisting process.Ring float comprises four watertight compartments, and each nacelle comprises a water injection hole, an osculum and a steam vent, and after water filling, all of hole uses screw threads for fastening to seal.
2, lifting device, lifting device is selected preferable 316 rustless steels of corrosion resistance, is connected with ring float latch by pull bar, it is simple to assemble.Hanger can realize 180 ° of rotations in spin direction, and in work progress, when floating block is rolled by hydrodynamic force, suspension rod can correct the metancenter of hanging object in time, it is to avoid topples or plays the generation turning round phenomenon.For the ease of construction, on lifting device, reserved hanger and substrate are to lift adnexa.
This ring float structure can meet dynamic cable and accessory kit installation exercise under water thereof, can realize buoyancy aid sedimentation to watertight compartment water filling, and the center of gravity realizing buoyancy aid hoisting structure by controlling the water injection rate of each watertight compartment regulates.Weight, by being articulated and connected, when floating block is rocked by environmental load effect, is not affected by the dynamic cable terminal of floating block carrying simultaneously and floating block.So that dynamically cable terminal and whole anchoring system under water are the most stable.
The above, it it is only presently preferred embodiments of the present invention, not the present invention is made any pro forma restriction, although the present invention is disclosed above with preferred embodiment, but it is not limited to the present invention, any those skilled in the art, in the range of without departing from technical solution of the present invention, when the technology contents of available the disclosure above makes a little change or is modified to the Equivalent embodiments of equivalent variations, in every case it is the content without departing from technical solution of the present invention, any simple modification above example made according to the technical spirit of the present invention, equivalent variations and modification, all still fall within the range of technical solution of the present invention.
