Fig. 1 has shown the situation that the penetrating cable 2 of existing underwater platform 1 and the equipment cable 4 of underwater platform external equipment 5 are connected by cable sealing device 3 in water.
Fig. 2 has shown that the cable sealing device 3 in Fig. 1 is by the situation that the equipment cable 4 of penetrating cable 2 and underwater platform external equipment 5 is connected and platform 1 carries out underwater sealing out of my cabin under water.As shown in Figure 2, cable sealing device 3 is made up of compression end cap 6, seal casinghousing 7, Upper gasket 8, lower gasket 10, sealing gasket 9, penetrating cable 2 and equipment cable 4, respectively through compression end cap 6, Upper gasket 8, lower gasket 10 and sealing gasket 9 in seal casinghousing 7, connect at the middle part of seal casinghousing 7.Cable sealing device 3 compresses Upper gasket 8 and sealing gasket 9 by compressing end cap 6, makes the space between sealing gasket 9 jam-packed penetrating cables 2, equipment cable 4 and seal casinghousing 7, realizes the connection sealing of penetrating cable 2 and equipment cable 4.
Underwater platform is all applied in Various Seasonal, often need to repeatedly dive under water in different depth, and what bore platform outside is the pressure and temperature environment of alternation, and this has proposed higher seal request to cable sealing device.Existing cable sealing device is as shown in Figure 2 to carry out crush seal pad 9 by tightening compression end cap 6, makes sealing gasket 9 inwalls of jam-packed seal casinghousing 7 and the sheath of hermetically-sealed cable, thereby realizes sealing.But, the penetrating cable 2 of plastic material sheath and equipment cable 4 are not rigid constraints, it is lower that gum filler is wound around sealing gasket 9 density ratios of making, under the repeated action of pressure and high low temperature, all can there is certain deformation, pretightning force can be more and more less, all can affect the thrust of sealing gasket 9 and seal casinghousing 7 and cable cover(ing), therefore, existing underwater platform cable sealing device is existing problems aspect sealing and anti-seawater seepage, affect the use of underwater platform.
Summary of the invention
For the underwater platform cable sealing device of prior art, exist along with the problem that seawater is revealed easily occurs underwater platform Reusability at different pressures and temperature, the utility model has been released the underwater platform cable sealing device of new structure, its object is improved optimization rubber gasket and upper, lower gasket coordinates with spring energy-storage assembly, by compressing exerting pressure of end cap, realize the sealing of the interior penetrating cable of seal casinghousing and equipment cable junction, so that underwater platform long-term use under temperature and pressure changing environment still obtains good cable seal, not producing any seawater leaks.
The underwater platform cable sealing device that the utility model is related, comprises and compresses end cap, seal casinghousing, spring energy-storage assembly, trapezoidal Upper gasket, rubber gasket, trapezoidal lower gasket.Seal casinghousing is cylinder-like structure, compression end cap is cylindrical structure, the seal casinghousing two ends compression end cap that is threaded respectively, two inner sides that compress end cap set gradually respectively spring energy-storage assembly, trapezoidal Upper gasket, rubber gasket, trapezoidal lower gasket, rubber gasket is the circular ring structure with trapezoidal groove, trapezoidal Upper gasket and trapezoidal lower gasket are the circular ring structure with trapezoidal projection, and spring energy-storage assembly forms by two butterfly spring pads are involutory.
The upper and lower both ends of the surface of rubber gasket all have circular trapezoidal groove, trapezoidal groove is corresponding with the circular trapezoidal projection of trapezoidal Upper gasket and trapezoidal lower gasket, and the circular trapezoidal projection of trapezoidal Upper gasket and trapezoidal lower gasket is inserted respectively in the circular trapezoidal groove of the upper and lower both sides of rubber gasket.
The underwater sealing that the underwater platform cable sealing device that the utility model relates to is connected at water with underwater platform external equipment cable for underwater platform penetrating cable.
When the application of underwater platform cable sealing device, successively compressing end cap, spring energy-storage assembly, trapezoidal Upper gasket, rubber gasket and trapezoidal lower gasket are enclosed within respectively one end of penetrating cable and equipment cable, then penetrating cable and equipment cable are put into respectively to seal casinghousing and be connected, spinning compresses end cap extrusion spring energy storage component again, push trapezoidal Upper gasket and rubber gasket carrys out jam-packed penetrating cable by spring energy-storage assembly, space between equipment cable and seal casinghousing, thereby realize the sealing that is connected that connects the penetrating cable of underwater platform and external equipment and equipment cable.
The underwater platform cable sealing device that the utility model relates to, by rubber gasket and upper lower gasket with trapezium structure, has increased transverse pressure, has increased the reliability of cable seal.Absorb and discharge by spring energy-storage assembly the energy that the rubber gasket deformation that causes due to alternating pressure and temperature produces, further improved the reliability of cable seal.And the seal casinghousing of described cable sealing device adopts corrosion resistant stainless steel to make, and has good underwater environment adaptability.
