Abstract
The utility model relates to an underwater vehicle cable running through pressure hull sealing leaking resealing device. The device comprises cables penetrating through pressure hulls and cup-shaped pipe junctions, wherein compressing screw caps are arranged at the two ends of each cup-shaped pipe junction; compressing packing washers, packing cords and padding used for sealing are arranged between the two compressing screw caps. The resealing device further comprises sealing fixtures arranged in a cabin, wherein the sealing fixtures are formed by two sealing fixtures fixedly connected with each other; each fixture comprises an opening pore with a smaller diameter on one side, an opening pore with a bigger diameter on the other side, a sealant injecting hole, a semicircular protruding retaining key and fastening bolts used for assembling; first sealing cavities used for accommodating sealants are arranged inside the sealing fixtures; second sealing cavities used for accommodating the sealants are arranged between the cup-shaped pipe junctions and the retaining keys. According to the utility model, resealing can be carried out without any modification on the conventional crossing-cabin sealing cup-shaped pipe junctions to block leaking.
Description
Technical field
The utility model relates to a kind of underwater sealing device, is specially a kind of submarine navigation device cable penetration pressure hull seal leakage seal arrangement again.
Background technique
The sealing of submarine navigation device cable penetration pressure hull is generally to adopt cup-shaped tube coupling to seal, referring to Fig. 1, cable 4 runs through pressure hull 2, adopt the coated cable of cup-shaped tube coupling 10 to seal simultaneously, wherein in two ends of the cup-shaped tube coupling 10 through inside and outside pressure hull, be provided with a clamping nut 8, between two compression nuts 8, be also provided with packing washer 9 and stuffing box packing rope 1 and stuffing box packing 3 simultaneously, but under the corrosion of seawater, use after a period of time, due to filler, the reasons such as packing washer is aging easily cause seal failure, especially when deep diving, more easily occur leaking, clamping nut 8 is because rust extremely cannot work.Changing cup-shaped tube coupling 10, to involve engineering too large, wastes time and energy.
Model utility content
In order to solve existing submarine navigation device cable penetration part seal leakage problem, the utility model provides a kind of submarine navigation device cable penetration pressure hull seal leakage seal arrangement again, it can, existing crossing cabin not being sealed the in the situation that cup-shaped tube coupling being done any change and sealed, block leakage.Wherein the utility model is realized by the following technical solutions:
The seal leakage of a kind of submarine navigation device cable penetration pressure hull is seal arrangement again, comprise cable and cup-shaped tube coupling through pressure hull, the crossing cabin part of the coated cable of described cup-shaped tube coupling, at cup-shaped tube coupling two ends, a clamping nut is respectively set, between two clamping nuts, be provided for the packing washer of sealing, wire packing and filler, described seal arrangement more also comprises the seal clamp being arranged in cabin, two that wherein said seal clamp is symmetry are formed by fixedly connecting, every fixture includes perforate and the larger perforate of opposite side diameter that a side diameter is less, retainingf key and the clamping bolt for assembling of hole for injecting glue and semicircular in shape convex shape, described seal clamp has assembled rear integral body and has been cylindric, wherein the less perforate of a side diameter is used for clamping penetrating cable, the perforate that opposite side diameter is larger is used for clamping the cup-shaped tube coupling of crossing cabin, be the retainingf key of convex shape for blocking clamping nut, described seal clamp inside is provided with the first Seal cage of accommodating sealer, between cup-shaped tube coupling and retainingf key, be also formed with the second Seal cage of accommodating sealer simultaneously.
Further, can also comprise another the identical seal clamp being arranged on out of my cabin.
After adopting seal arrangement more of the present utility model, can extend existing seal arrangement working life of 1 year, and this seal arrangement is more conveniently changed after occurring again leaking.
