Movement, it is final that upper half rotating ring 10 and lower half rotating ring 3 is promoted to be rotated by 90 ° together so that upper half is close so as to which gear ring 9 be driven to be rotated by 90 °
Seal 16, section junction and upper half stationary ring 13, the section junction of lower half stationary ring 19 of lower half sealing ring 20 are staggered 90 °, from
And avoid the section junction leak of upper half sealing ring 16 and lower half sealing ring 20.
As shown in Figure 1, sealing device is separated along the binding face of wall end face of flange and lower 1 end face of hatch board, including above enclosing
Wall part and lower hatch part, the original state of sealing device fit closely for upper 5 end face of wall flange and lower 1 end face of hatch board
Together, submerged cable 15 is not passed through sealing device at this time.Lower half rotating ring 3 and lower half stationary ring 19 and lower half base in sealing device
The assembling form of seat 2 is as shown in figure 4, upper half rotating ring 10 and upper half stationary ring 13 assemble therewith with upper half pedestal 8；Wherein lower half
The structure type of rotating ring 3 is shown in Fig. 5, and the structure type of upper half rotating ring 10 is therewith；19 structure of upper half stationary ring 13 and lower half stationary ring
Form is shown in Fig. 6；The structure type of lower half pedestal 2 is shown in Fig. 7, and the structure type of upper half pedestal 8 is therewith.
On the one hand assembling sealing surface in Fig. 4 can coordinate hatch board sealing ring 4 to upper wall flange 5 and lower hatch board 1
End face generates sealing, on the other hand upper half sealing ring 16 and lower half sealing ring 20 is coordinated to generate radial seal to submerged cable 15.
When there is submerged cable 15 to need to proceed directly to carry out maintenance in dry and wet conversion cabin, lower hatch board 1 is just opened, makes water
Lower cable 15 bends to two sections, and one section passes through out of a sealing device, and another section passes through out of another sealing device, then
Turn off lower hatch board 1 so that submerged cable 15 is just stuck in upper half rotating ring 10 and lower half rotating ring 3, upper half stationary ring 13 and lower half
Between stationary ring 19, as shown in Figures 2 and 3.At this point, between upper half rotating ring 10 and lower half rotating ring 3, upper half stationary ring 13 and lower half stationary ring
It fits together between 19 along split surface, between upper half rotating ring 10 and upper half stationary ring 13, between lower half rotating ring 3 and lower half stationary ring 19
Be marked with lubricating grease due to precision assembly, and in fitting surface, can generate assembling sealing surface, thus at this will not leak, see Fig. 4；
Upper half sealing ring 16 and lower half rotating ring on upper half rotating ring 10 about 3 semitight circle 20 combine, to submerged cable 15 into
The preliminary radial seal of row.Then underwater electric push rod 7 promotes rack 11 to move along a straight line, so as to which gear ring 9 be driven to be rotated by 90 °, most
Eventually upper half rotating ring 10 and lower half rotating ring 3 is promoted to be rotated by 90 ° together so that upper half sealing ring 16, the section knot of lower half sealing ring 20
Stagger 90 ° with upper half stationary ring 13, the section junction of lower half stationary ring 19 at conjunction, at this time upper half sealing ring 16, lower half sealing ring 20
Combine not only can generate radial seal to submerged cable 15, but also can generate end face seal, close so as to avoid upper half
Water in cabin is extracted into out by seal 16 and the section junction leak of lower half sealing ring 20, final dry and wet conversion cabin, so as to
Submerged cable 15 is carried out maintenance and safeguarded.
Above description is explanation of the invention, is not the restriction to invention, limited range of the present invention is referring to right
It is required that within protection scope of the present invention, any type of modification can be made.
