Cable sealing device for underwater platform

Abstract

The invention discloses an underwater platform cable sealing device. The underwater platform cable sealing device comprises a sealing housing which is of a cylinder structure; two ends of the sealing housing are in threaded connection with two compression end covers respectively; a spring energy storage assembly, a trapezoidal upper gasket, a rubber sealing gasket and a trapezoidal lower gasket are arranged on the inner side of each compression end cover in turn; the rubber sealing gaskets are of circular ring structures with trapezoidal grooves; the trapezoidal upper gaskets and the trapezoidal lower gaskets are of circular ring structures with trapezoidal projections; the spring energy storage assemblies are formed by two butterfly spring gaskets through folding respectively. During application, the compression end covers, the spring energy storage assemblies, the trapezoidal upper gaskets, the rubber sealing gaskets and the trapezoidal lower gaskets sleeve one ends of cabin penetrating cables and equipment cables in turn, the cabin penetrating cables and the equipment cables are placed into the sealing housing and connected with each other, and the inside of the watertight housing is compressed through the compression end covers, and accordingly the reliable sealing of cable connection between an underwater platform and external devices is achieved.

Description

technical field [0001] The invention relates to underwater cable sealing, in particular to an underwater platform cable sealing device under the environment of alternating pressure and temperature change. Background technique [0002] The use of underwater platforms in the ocean is becoming more and more widespread. In addition to being used in ocean observation, it has been widely used in scientific investigation, underwater entertainment services, and ocean engineering. Watertight cables are inseparable between the surface mother ship and the underwater platform and between the equipment of the underwater platform body. Therefore, the sealing of underwater cables to prevent seawater leakage is an important technical problem in the use of underwater platforms. [0003] figure 1 It shows the condition that the penetrating cable 2 of the existing underwater platform 1 and the equipment cable 4 of the external equipment 5 of the underwater platform are connected through the c...

AI Technical Summary

Problems solved by technology

[0006] In view of the prior art cable sealing device for underwater platforms, there is a problem that seawater leakage is likely to occur as the underwater platform is used repeatedly under different pressures and temperatures. The present invention introduces a cable sealing device for underwater platforms with a new structure, the purpose of which is to The optimized and improved rubber gasket and the upper and lower gaskets are matched with the spring energy storage component, and the pressure of the compression end cover is applied to realize the sealing of the connection between the cabin penetrating cable and the equipment cable in the sealed shell, so that the underwater platform can withstand temperature Long-term use under pressure-changing environments can still get a good cable seal without any seawater leakage
