Pipeline butt joint waterproof structure

Abstract

The invention discloses a pipeline butt joint waterproof structure. The pipeline butt joint waterproof structure comprises a connecting pipe (1), a sleeving piece (2) and a clamping piece (3), the connecting pipe (1) is connected to the outer wall of the connecting ends of the sleeving piece (2) and the clamping piece (3) in a sleeving mode, the sleeving piece (2) is detachably connected with theclamping piece (3), a plurality of limiting connecting assemblies (4) are further connected between the sleeving piece (2) and the clamping piece (3) in a clamped mode, and the limiting connecting assemblies (4) are annularly arranged on the outer side wall of the connecting pipe (1). Sealing between the sleeving piece and the clamping piece is achieved through threaded fastening of a fourth connecting pipe and a second connecting pipe, meanwhile, due to the fact that a conical sealing ring is elastic rubber conical sealing, the hidden danger of sealing failure caused by vibration of the connecting pipe is eliminated structurally, the sealing effect and the long-term sealing effect are also guaranteed, and meanwhile, the defects that underwater construction is difficult, and the sealing effect and attractiveness are difficult to guarantee are also overcome.

Description

technical field [0001] The invention relates to a docking structure, in particular to a docking waterproof structure for underwater pipelines, which belongs to the technical field of underwater robot construction. Background technique [0002] Underwater robots are developing rapidly in the direction of miniaturization and intelligence. Especially in recent years, some underwater operation industries urgently need economical and practical small intelligent underwater robots to replace bulky and expensive heavy-duty operating underwater robots. With the development of science and technology and life, there are more and more underwater operations, but the danger and unpredictability of underwater operations are too great, and different underwater robots are required to operate in different situations, providing support for underwater production, scientific research, The work caused a lot of trouble and the cost was very high. [0003] However, the pipe butt joint waterproof s...

Problems solved by technology

With the development of science and technology and life, there are more and more underwater operations, but the danger and unpredictability of underwater operations are too great, and different underwater robots are required to operate in different situations, providing support for underwater production, scientific research, The operation caused a lot of trouble and the cost was very high

[0003] However, the pipe butt joint waterproof structure used in the existing underwater robots has complicated connection technology, and at the same time, it is difficult for the staff to assemble and overhaul, and the joint waterproof structure has a structural form that is sealed due to the vibration of the connecting pipe. The hidden danger of failure also leads to poor sealing effect and difficult sealing construction
