Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] The present invention designs a wall-penetrating structure that can be applied underwater to realize the underwater photoelectric composite cable from being sealed in the water and penetrating into the underwater sealed cabin. Watertight inside and outside, can be easily installed and disassembled. The specific structure is:

[0036] Such as figure 1 As shown, the present invention comprises sealing screw sleeve 1, compression screw sleeve 2, wall-piercing sleeve 3, compression wedge 4, sealing plug 5 and adjusting gasket 6, wherein the flange 18 at one end of wall-piercing sleeve 3 is connected to the underwater The airtight cabin body is sealed and connected, and the end is provided with a sealing plug 5 that is in sealing contact with the inner wall of the wall sleeve 3, and the end is threaded with a sealing screw sleeve 1; the other end of the w...

Abstract

The invention relates to an underwater sealing wall penetrating structure. A flange plate at one end of a wall penetrating sleeve is in sealed connection with an underwater sealing cabin, a sealing plug connected with the inner wall of the wall penetrating sleeve in a sealed abutting manner is contained in the end, and the end is in threaded connection with a sealing screw sleeve. The other end ofthe wall penetrating sleeve is in threaded connection with a pressing screw sleeve. One end of the pressing screw sleeve is inserted into the wall penetrating sleeve and is connected with the inner wall of the wall penetrating sleeve in a sealed abutting manner, the other end of the pressing screw sleeve is located outside the wall penetrating sleeve, a sealing plug is contained in the other endof the pressing screw sleeve, and the other end of the pressing screw sleeve is in threaded connection with a sealing screw sleeve. A pressing wedge is contained in the wall penetrating sleeve and located between the pressing screw sleeve and the sealing plug contained in one end of the wall penetrating sleeve. An underwater photoelectric composite cable sequentially penetrates one sealing screw sleeve, one sealing plug, the pressing screw sleeve and the pressing wedge. The outer surface of the pressing wedge is connected with the inner wall of the wall penetrating sleeve in an abutting manner, and the inner surface of the pressing wedge is of a tooth structure achieving axial fixing with the underwater photoelectric composite cable. The underwater sealing wall penetrating structure does not depend on vulcanization sealing, watertightness inside and outside the cabin is guaranteed in a mechanical sealing manner, and mounting and separating of the photoelectric composite cable and the cabin can be conveniently achieved.

Description

technical field [0001] The invention relates to supporting facilities of an underwater sealing cabin body, in particular to an underwater sealing wall penetration structure for realizing the underwater sealing penetration of an underwater photoelectric composite cable into the underwater sealing cabin body. Background technique [0002] The underwater sealed cabin is a cabin structure that is used in an underwater environment and integrates a large number of electronic devices inside. It is widely used in underwater engineering equipment, underwater monitoring, submarine observation networks, and underwater robots (ROV, AUV etc.) and national defense and many other fields. The underwater sealed cabin is often connected with a photoelectric composite cable by using a sealed wall-through structure according to work needs. Usually, the through-wall sealing structure is to realize the fixed connection of the photoelectric composite cable and the metal wall-piercing parts by rub...
