Problems solved by technology

Applying friction stud welding to underwater welding will inevitably require the use of underwater robot ROV (Remotely Operated Vehicle) for remote control operations. Therefore, the use of friction stud welding to connect underwater sacrificial anodes must be as simple as possible. The welding operation is too cumbersome, and the welding quality cannot be guaranteed

Abstract

The invention discloses an underwater sacrificial anode connecting device and an underwater sacrificial anode connecting method. The device comprises a connecting base plate (2), a fixed stud (3) and a fixed nut (5). The method comprises the following steps: integrally casting a sacrificial anode (1) and the connecting base plate (2), and forming a stud through hole (21) in the connecting base plate (2); causing the fixed stud (3) pre-provided with the fixed nut (5) to vertically penetrate through the stud through hole (21), and fixing the bottom end of the fixed stud (3) together with a target connecting object (4) in a friction stud welding manner; downwards rotating the fixed nut (5) until the connecting base plate (2) is locked with the target connecting object (4), thereby fixing the sacrificial anode (1) on the target connecting object (4). According to the device and the method, underwater sacrificial anode connecting operation can be effectively simplified on the premise of ensuring welding quality; moreover, when the device and the method are applied to the welding of a deep-water steel structure, saturation diving welding can be replaced, so that construction cost is greatly lowered.

Description

technical field [0001] The invention relates to the technical field of underwater connection, in particular to an underwater sacrificial anode connection device and a connection method. Background technique [0002] At present, there are many kinds of underwater connection methods being researched and applied in countries all over the world, but the basic technical development direction is: to adapt to deeper water depth, provide higher connection quality, and improve the level of automatic operation to a greater extent. Mechanical connectors, underwater wet welding and underwater dry welding are currently more common underwater connection methods; mechanical connectors have the advantages of simple installation, low price, and not affected by water depth, but sometimes reduce the performance of structures; Underwater wet welding has the advantages of simple equipment, low cost, flexible operation, and strong adaptability, but the welding quality is poor; although underwater...
