Abstract
The invention relates to an ocean platform complex node underwater maintenance cover, which mainly provides a dry welding space for the repair of underwater complex nodes of an ocean jacket platform, so that dry welding can be effectively implemented underwater. The ocean platform can suffer damage of different classes and degrees in service, particularly a crack appears at a weld position of the underwater complex nodes of the jacket platform due to different external forces or fatigue, and the most efficient means for relevant repair is to weld; although underwater wet welding can carry out a certain degree of welding repair, the fatigue performance of the underwater wet welding can not be compared to the dry welding. The invention aims to provide a water-free space in a larger space needing welding repair, so that underwater dry welding can be successfully implemented, and the drying property of a surrounding space is also kept during weld cooling.
Description
Technical field
The present invention relates to the underwater maintenance detection range, specifically is the ocean platform underwater maintenance cover.
Background technology
The offshore platform structure Service Environment is abominable, mainly suffers the effect of wind, wave, stream, earthquake, sea ice or the like load, and its failure consequence is serious, thereby safety guarantee becomes the problem that people pay close attention to.Simultaneously, effectively prolong the service life of ocean platform, can reduce marine petroleum development cost, remarkable in economical benefits greatly.The maintenance of ocean structure and equipment have many maintenances by land meet less than difficulty, underwater maintenance just is difficult to implement.Welding (doing weldering) is considered to best platform maintenance and reinforcement means, does weldering even also often adopt under more abominable underwater construction environment.Need complicated welding chamber but do weldering under water, the design and manufacture cost height of welding chamber, the welding maintenance implementation cost of welding maintenance performance difficulty, especially complex node is higher, and enforcement of the present invention can effectively reduce corresponding maintenance cost.
Summary of the invention
The main square law device of ocean platform complex node underwater maintenance cover is as follows:
(1) device is mainly by umbrella hood (cabin) 1, counterweight 2, air input pipe compositions such as (can establish in addition, not draw among the figure), as Fig. 1.
(2) umbrella hood is formed (connecting to form through slide fasteners etc. by two at least) by dry goods material (as canvas etc.), inflated condition can be as Fig. 2, and maintenance cover is formed (whether transparent among the figure only it belongs to the different sheets of forming for explanation) by opaque section A and two of transparent part B among the figure.The position D of different sheet combinations among the figure is by connections such as slide fasteners, with several local stronger clip device sealings of pardon and fixing of adopting such as structure or input air pipeline intersection C.
(3) the bottom counterweight is the weight decision of maintenance cover emptied of water according to the size of maintenance cover, and is circumferentially uniform, with umbrella hood bottom lucky sagging being advisable behind inflation.
Description of drawings
Fig. 1 is the schematic three dimensional views that the duty of invention is, Fig. 2 is that the top umbrella hood of complex node maintenance cover is divided into two-part schematic diagram, and Fig. 3 is the sealing and the fixing means schematic diagram of maintenance cover and member intersection area.
The specific embodiment
Referring to accompanying drawing.The ocean platform complex node underwater maintenance cover primary structure is formed and is made up of cave catcher cabin 1, the bottom counterweight 2 on top, as Fig. 1.(at least two of sheets are formed in different umbrella shape cabins, A among the outside a slice Fig. 2 of node, B among inner a slice Fig. 2) assembling is under water fixed, is sealed with the clip that structure intersection (as C point position among Fig. 2) adopts pardon to have rubber liner or other liner preferably, as Fig. 3.Different composition sheets connect by slide fastener, in the inside, slide fastener place of seam magic tape can be set.The regular counterweight that is provided with after different sheet assemblings are finished is carried out the air input of maintenance cover inside, afterwards until the complete expansion of umbrella shape maintenance cover.Keep an amount of air input, require the input air amount to be not less than umbrella shape maintenance cover wastage, can carry out the preparation (as cleaning marine growth, rust cleaning etc.) of weld zone afterwards and specifically implement welding etc., finish until welding that weld seam is handled and cooling finishes, air stops input.
Claims (5)
1. an ocean platform complex node underwater maintenance cover is characterized in the non-closure property of the opening of covering, and it is the semiclosed umbrella hood and the corresponding bottom counterweight of a lower openings.
2. the characteristics of complex node underwater maintenance cover are that top is a cloth matter (canvas or other fabrics also or material such as Polypropylence Sheet) umbrella, and counterweight is arranged at the bottom, and umbrella is formed by at least two, adopt slide fastener etc. to be connected between sheet and the sheet.
3. umbrella and node component intersection are adopted the clip etc. of rubber liner to seal and are fixing, whole umbrella and with the node contact position, allow the part seepage of gas.
4. complex node underwater maintenance cover is assembled finish (and the suitable counterweight of configuration) under water, carry out the input of air, after treating that the maintenance cover expansion is stable, keep the input of gas, guarantee to import gas and be not less than the maintenance cover leakage air, the related work that can weld finishes until welding, the weld seam cooling.
5. underwater maintenance cover not only can be used for welding under water, equally the drying property at its maintenance (complexity) node place can detect, activity such as application.
