Embodiment Construction
[0009] The present invention will be further described below in conjunction with drawings and embodiments.
[0010] Such as figure 1 As shown, the water inlet swivel joint of the submarine pipeline and optical cable embedding device of the present invention includes a core sleeve 1, a compression sleeve 2, a cylinder body 3, a joint 4, and an oil-immersed asbestos disc 5.
[0011] The cylinder body 3 and the hinge 4 are fixedly and airtightly connected with fasteners and seals. The core sleeve 1 and the cylinder body 3 are connected in a rotary and sealed manner through an oil-immersed asbestos disc 5 and a compression sleeve 2 .
[0012] The outer circle of the core sleeve 1 is movably connected with the step hole in the inner hole of the cylinder body 3, and there is a gap between the outer circle of the core sleeve 1 and the inner hole of the cylinder body 3, and the oil-immersed asbestos disc 5 is placed in the gap, and the oil-impregnated asbestos disc 5 is placed in the...

The invention relates to an inflow rotating hinge connector for a submarine pipeline and optical cable embedding device. The inflow rotating hinge connector comprises a core sleeve, a compression sleeve, a drum, a hinge joint and an oil-immersed asbestos disc. The core sleeve is in rotating seal connection with the compression sleeve through the oil-immersed asbestos disc. An excircle of the core sleeve is in movable connection with a step hole in an inner hole of the drum in a matching mode, a gap is reserved between the excircle of the core sleeve and the inner hole of the drum, the oil-immersed asbestos disc is arranged in the gap, one end of the oil-immersed asbestos disc clings to the end face of the step hole of the drum, the other end of the oil-immersed asbestos disc is contacted with the compression sleeve sleeved on the excircle of the core sleeve, the oil-immersed asbestos disc is compressed through the compression sleeve, so that the core sleeve is in rotating seal connection with the drum. The compression sleeve is connected onto the drum through a fastener, and compression of the oil-immersed asbestos disc is achieved by adjusting the fastener. The inflow rotating hinge connector for the submarine pipeline and optical cable embedding device can achieve full hard pipe management of an underwater inflow system of the submarine pipeline and optical cable embedding device so as to solve a series of problems caused by use of high pressure hoses and enable the water supply system of the embedding device to be reliable and safe, and use cost is reduced.
Description
technical field [0001] The invention relates to a submarine pipeline optical cable embedding device, in particular to a water inlet swivel joint in the optical cable embedding device. Background technique [0002] At present, the water inlet system of submarine pipelines and optical cable embedding devices at home and abroad all use high-pressure leather pipes for water supply. Even if some of the more advanced products use submersible pumps for water supply, since the hydraulic knife of the buried device is a rotating part, it is still necessary to use a section at the position of the hydraulic knife. High pressure hose transition. However, the use of high-pressure leather tubes has problems such as high cost, damage, and poor reliability. Contents of the invention [0003] The present invention aims to solve the technical problems of high cost, damage and poor reliability of the existing water inlet system of optical cable embedding devices using high-pressure leathe...
