Abstract

The invention relates to a simple and easy underwater welding chamber of an ocean platform, which is mainly used for the underwater welding of an ocean structure, in particular for providing a 'dry' welding area protection not contacting seawater for the underwater welding of an offshore oil exploitation platform. The underwater welding is a difficult problem for ocean engineering in particular in the welding repair of the ocean structure; and for the welding of an important key structure, a high-pressure welding chamber is generally adopted overseas, and a sealed chamber is established overland and then is lowered to a welding part so that a welding worker and a welding area electric arc are in a 'dry' environment. The dry method welding has high welding seam quality, but the device structure is complex, particularly the welding airtightness requirement of the welding chamber is high, the structure is bulky, and the earlier stage welding and the sea lowering and the like of the welding chamber occupy most of the time for the whole welding construction, so the time used for performing the underwater welding implementation is not much. Another method is to perform underwater 'wet' welding, namely special underwater welding wet-welding equipment is used for implementing the welding and the electric arc is burnt underwater, so the method is simple and convenient to operate and has wide adaptability. However, the electric arc of the underwater welding is instable, the welding seam molding is not good, the quality is not high and the mechanical properties are poor, so the welding with low welding seam quality requirements can be implemented by the wet welding, but the welding with high welding seam quality requirements needs the dry welding. The invention aims to provide the simple and easy underwater welding chamber of the ocean platform which can ensure the welding quality, reduce the cost, and save the construction time.

Description

A kind of simple and easy underwater welding chamber of ocean platform
Technical field
The present invention relates to the under-water welding field, specifically is the simple and easy under water welding chamber of platform of marine petroleum development.
Background technology
Ocean structure generally all has the characteristics of high investment, especially offshore platform cost height, build, cost of installation is big, wishes that construction structure prolongs its service life as much as possible under the situation of safety, it is to drop into the big economic activity of little output that actv. keeps in repair ocean structure.And for the repairing of ocean structure, under-water welding occupies very big work capacity, thereby the device and the technology of each link of whole welding process are studied, and helps the reduction of maintenance cost.Though wet welding under water is cost-cutting to a certain extent, welding quality is difficult to guarantee that it is complicated that dry type welding chamber commonly used has construction again, and the shortcoming that cost is high the invention provides the easy underwater welding chamber of the simple and easy economy of a kind of economy.
Summary of the invention
A drying is provided, is not protected purpose by the welding region of contact with sea water for being reached for under-water welding, main square law device is as follows:
(1) device mainly is made up of umbrella hood, support frame, sealing arrangement, life line, exhaust smoke hole etc., as Fig. 1.
(2) umbrella hood is that real needs according to the weld are divided into several, if pile and so on rising structure can carry out as Fig. 1, if other comparatively complicated node then needs to set up the semiclosed cabin of corresponding geometric configuration back-off, but the contact of weld disengaging water after the palpus assurance emptied of water.
Description of drawings
The last figure of Fig. 1 is according to the designed structural representation that goes out of the present invention, is the cutaway view in the middle of umbrella hood, and figure below is the birds-eye view of structure.
The specific embodiment
As scheming similar umbrella shape device (tubular or other shapes), wherein the B point with pile contact position A and support frame can adopt clip that the umbrella shape device is waled according to the situation manufacturing of weld, so that its rigidity increases, becomes as a whole.Each part of umbrella hood has a support frame, and pile contact position A and umbrella hood between to suitably seal.After device installed under water, by water surface ship or platform input air (or other protection-gas weldings etc.) in umbrella hood, the inner seawater of emptying broke away from the water contact with the position of needs welding.Can implement welding afterwards, wherein exhaust smoke hole is when welding chamber owing to during smog obstruction welding procedure that welding produces, opening the usefulness of discharging fume.In welding process, to guarantee the gas capacity in the cabin, also can carry out the input of air always, finish, the weld seam cooling until welding.

Claims (3)

1. easy easy underwater welding chamber of ocean platform is characterized in the non-closure property of opening in cabin, and it is a semi-enclosed rigidity cover.
2. the characteristics of simple and easy welding chamber are that assemble at the weld piecemeal in the cabin, water emptying in input air or other gas will cover after assembling finishes, thus form chamber, to-be-welded region and water are isolated, the weld is in by among the gas encirclement.
3. the cover of simple and easy welding chamber.Be primarily characterized in that providing when welding and welding back a period of time weld seam to be in gas surrounds among the protection, water is by the emptying of input gas (air or other protection-gas welding) in the rigidity cover of assembling back.
