Problems solved by technology

However, generally speaking, the size of the local dry welding drainage cover at home and abroad is relatively large, which not only affects the precise positioning of the underwater welding torch of the welding robot, but also has great limitations in engineering applications, and poor adaptability to different positions of the process. Slow speed and low production efficiency

Embodiment 1

[0028] Such as Figure 1 ~ Figure 3 As shown, the partial dry-process underwater robot welding micro-drainage cover of this embodiment includes an inner air cover 5, an outer air cover 11 and a water retaining jacket 12 arranged in sequence from the inside to the outside. A welding torch installation hole 3 for setting a welding torch is formed inside the inner gas cover 5; the wall of the welding torch installation hole 3 is provided with an internal thread for installing a welding torch. A convergent shrinking nozzle cavity 13 is formed between the outer air cover 11 and the inner air cover 5; the top cover of the shrinking nozzle cavity 13 is provided with a sealing cover 6; the outer air cover 11 is connected with four air intake pipes 7; The lumens of each intake pipe 7 communicate with the contracting nozzle cavity 13 to realize the input of compressed gas. The water blocking jacket 12 is made of flexible high temperature resistant composite material. The water retaini...

Embodiment 2

[0041] In this embodiment, the double airflow structure local dry process underwater robot welding miniature drainage cover, such as Figure 4 As shown, it is applied to underwater fillet welding. During underwater fillet welding, the workpieces are perpendicular to each other, and the water retaining sleeve 12 is cut into a V shape according to actual requirements to adapt to actual engineering applications. The rest of the structure of this embodiment is the same as that of Embodiment 1.

Abstract

The invention provides a micro-drainage cover for local dry-process underwater robot welding with a dual-airflow structure, which is characterized in that: it includes an inner air cover, an outer air cover and a water-retaining jacket arranged sequentially from the inside to the outside; the inside of the inner air cover A welding torch installation hole for setting the welding torch is formed; a converging shrinking nozzle cavity is formed between the outer gas cover and the inner gas cover; the top cover of the shrinking nozzle cavity is provided with a sealing cover; the outer The gas hood is connected with at least one intake pipe; the lumen of the intake pipe communicates with the cavity of the shrinking nozzle to realize the input of compressed gas; the water retaining sleeve is connected with the outer gas hood to form a slag discharge cavity; the lower part of the torch installation hole and the lower part of the cavity of the shrinking nozzle communicate with the slag discharge cavity respectively. The drainage cover has a reasonable structure, small size, flexible application, good drainage and protection effects on the welding area, and can improve the quality of underwater welding.

Description

technical field [0001] The invention relates to the technical field of welding equipment for underwater robots, and more specifically relates to a miniature drainage cover for welding underwater robots with a dual-airflow structure and local dry method. Background technique [0002] With the rapid development of the national economy and the urgent needs of energy strategies, a large number of marine engineering construction and nuclear power plant equipment maintenance require underwater welding operations. As one of the key technologies of ocean engineering, underwater welding has attracted much attention. From the installation and construction of offshore oil and gas platforms to the laying and maintenance of submarine pipelines, from the emergency repair of large ships to the repair of spent fuel pools in nuclear power plants, underwater welding operations are more and more widely used. [0003] At present, the underwater welding methods mainly include three methods: wet...
