The end cap of one end, so that it may which interior instrument is all taken out or loaded.If improve space availability ratio（Utilize cylinder internal diameter）,
Due to the obstruction of stiffening ring, instrument need to be divided into two parts, after the end cap for dismantling two ends, respectively could be taken out instrument from two ends
Or load, cause the very big inconvenience of dismounting.
In view of the above-mentioned problems, the instrument inside stiffening ring and pressure cylinder is linked to be into an entirety, stiffening ring and pressure-bearing cylinder
Gap fiting mode is used between body, in order to dismount.One advantage of the cylinder of circular section is：In uniform external effect
Under, cylinder only produce uniform shrinkage deformation, inner barrel there was only homogeneous compaction stress and without bending stress.If cylinder and reinforcement
Gap width between circle is taken as in the safe allowed band of pressure cylinder uniform shrinkage deformation（That is pressure cylinder regime of elastic deformation
It is interior）, then on the one hand can strengthen the non-deformability of pressure cylinder, on the other hand can improve inner barrel space availability ratio again, just
In dismounting.
The deformation range of cylinder is limited within reasonable benefit/risk value by the present invention by stiffening ring, is not being increased wall thickness or is being lacked
Under conditions of amount increase wall thickness, the deep-sea compressive ability of cylinder is improved, and do not reduce the free space of inner barrel.
The content of the invention
Present invention aims at by the gap fiting mode between cylinder and stiffening ring there is provided one kind it is simple and effective plus

Between there is gap, can easily install or remove the instrument and equipment in pressure cylinder 1；When deep-sea works, pressure cylinder 1 by
Deep sea pressure and shrink, gap width is gradually reduced, and now bear pressure is pressure cylinder 1 itself；As depth increases seawater
Pressure is persistently raised, and the gap width between pressure cylinder 1 and stiffening ring 2 is reduced to zero, and now stiffening ring 2 is total to pressure cylinder 1
It is same to bear seawater pressure.
In the present invention, pressure cylinder 1 is thin cylinder, inner wall smooth.For installing and protecting the instrument of inner barrel to set
It is standby.Its error in geometrical form permissible value should be controlled strictly, and consider certain stability margin of safety.
In the present invention, stiffening ring 2 is using metal or nonmetallic smooth torus with one fixed width, the appearance of stiffening ring 2
Face is shiny surface.The material of stiffening ring 2 should have enough bending rigidities, and cross sectional moment of inertia is big, and shaping will facilitate.
In the present invention, the connection of stiffening ring 2 and instrument mounting bracket 3 is using threaded connection or welding manner, to determine instrument
Device equipment and the relative position of stiffening ring 2, it is then overall to be fitted into pressure cylinder 1.
In the present invention, when pressure cylinder 1 is longer, it can be combined into a frame structure to fix using multiple stiffening rings 2
