Local dry type drainage device for underwater welding robot and drainage method thereof

Abstract

The invention discloses a local dry type drainage device for an underwater welding robot and a drainage method thereof. The local dry type drainage device for the underwater welding robot comprises an upper end cover, an outer drainage cover body, an inner drainage cover body and a spoiler, wherein the inner drainage cover body is arranged in the outer drainage cover body, the lower end of the outer drainage cover body and the lower end of the inner drainage cover body are open, and the upper end of the outer drainage cover body and the upper end of the inner drainage cover body are sealed and fixed through the upper end cover; an installation hole for a welding gun and a high-pressure gas inlet are formed in the upper portion of the upper end cover, and high-pressure gas is introduced into an inner cavity of the outer drainage cover body and an inner cavity of the inner drainage cover body. The local dry type drainage device for the underwater welding robot is reasonable in design, reliable in performance, simple in structure and convenient to use, the problem that the underwater welding robot is affected by the water environment factor when used for welding can be effectively solved, welding can be conducted by the underwater welding robot smoothly by the adoption of the drainage device, and the welding efficiency and the welding quality of the underwater welding robot are improved.

Description

technical field [0001] The invention relates to an underwater welding drainage device, in particular to a local dry drainage device for an underwater welding robot and a drainage method thereof. Background technique [0002] With the rapid development of the national economy, the continuous development and utilization of terrestrial resources has resulted in a shortage of resources. As a result, terrestrial energy can no longer meet people's living needs, so people have sought new energy from the deep sea, which has promoted the continuous development of marine engineering. It is an important technology that is receiving more and more attention. From the installation and construction of offshore oil and gas platforms to the laying and maintenance of submarine pipelines, as well as underwater maintenance of nuclear power, underwater welding can be seen everywhere. However, the welding work in this seawater is affected by the water environment factors. It is necessary to use r...
