Problems solved by technology

Although robots are used in the maintenance of many other nuclear power equipment, a mature and practical underwater remote control welding system has not yet appeared. At present, manual welding is performed by diving welders wearing heavy professional protective clothing
Submersible welders weld by hand and are directly exposed to the radiation environment. Moreover, because the power station c...

Abstract

The invention discloses an underwater welding test chamber, which comprises a cylinder (1), a fast opening door device (2) and a clamping rotation locking device (3); wherein a cylinder flange (15) is arranged on the upper edge of the cylinder (1); a plurality of small-diameter nozzles (11), large-diameter nozzles (12), higher viewing lens (13) and lower viewing lens (14) are provided along the circumferential direction of the cylinder (1); a filter net (16), a water in-and-out nozzle (17) and a supporting seat (18) are arranged at the bottom end of the cylinder (1); a clamping rotation oil tank (34) drives a clamper (31) to rotate corresponding to the cylinder (1) so as to fasten an external block button (33) with an internal block button tightly; only when underwater welding test is finished, the clamper (31) can release a fast opening door (21), and an opening door oil tank (25) opens the fast opening door (21). The invention is used for the underwater welding test, and can achieve a simple and reliable connection and sealing of tubes and cables between internal equipments and external equipments; the test pressure can be preset, and the test operation is safe and convenient and the test efficiency is high.

Description

technical field [0001] The invention relates to an underwater welding test chamber, in particular to a vertical pressure vessel with a quick-opening door for underwater welding experiment research. Background technique [0002] There are many radioactive containers in nuclear power plants, such as reactor pressure vessels, evaporators, pressurizers, condensers, spent fuel pools, refueling pools, feed water pools, etc. Due to nuclear radiation stress and other effects, radioactive containers are prone to corrosion cracks and surface abrasions that seriously threaten the safe operation of the power station. Welding repairs such as leak repair welding, crack opening groove repair welding, and wear and corrosion surface overlay welding are required. To reduce repair costs and radiation effects, welding is performed in water. Although robots are used in the maintenance of many other nuclear power equipment, a mature and practical underwater remote control welding system has not ...
