Description
Technical field
The present invention relates to submerged cable sealing, particularly relate to the underwater platform cable sealing device under alternating pressure and variations in temperature environment.
Background technology
The use of underwater platform in ocean is more and more extensive, except being applied to oceanographic observation, being obtained for and applying widely in scientific investigation, under water entertainment service, ocean engineering etc.All be unable to do without watertight cable between surface mother ship and underwater platform and between each equipment of underwater platform body, therefore submerged cable seal anti-seawater seepage be underwater platform use in an important technological problems.
The equipment cable 4 of penetrating cable 2 and underwater platform external equipment 5 that Fig. 1 shows existing underwater platform 1 in water by situation that cable sealing device 3 is connected.
Fig. 2 cable sealing device 3 shown in Fig. 1 is connected with the equipment cable 4 of underwater platform external equipment 5 by penetrating cable 2 and platform 1 carries out the situation of 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 are each passed 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 sealing gasket 9 jam-packed penetrating cable 2, space between 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 needs repeatedly to dive under water in different depth, and the pressure and temperature environment of what platform exterior bore is alternation, this proposes higher seal request to cable sealing device.Existing cable sealing device as shown in Figure 2 carrys out crush seal pad 9 by tightening compression end cap 6, makes the inwall of sealing gasket 9 jam-packed seal casinghousing 7 and the sheath of hermetically-sealed cable, thus realize 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 ratio made, all certain deformation can be there is under the repeated action of pressure and high/low temperature, 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 in 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 underwater platform under different pressure and temperature conditions Reusability easily occur seawater reveal problem, the present invention is proposed the underwater platform cable sealing device of new structure, its object is to the rubber gasket of Optimal improvements and upper, lower gasket coordinates with spring energy-storage assembly, by compressing exerting pressure of end cap, realize the sealing of penetrating cable and equipment cable junction in seal casinghousing, so that underwater platform Long-Time Service under temperature and pressure changing environment still obtains good cable seal, do not produce any seawater to leak.
Underwater platform cable sealing device involved in the present invention, 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, seal casinghousing two ends are threaded compression end cap respectively, two inner sides compressing end cap set gradually spring energy-storage assembly, trapezoidal Upper gasket, rubber gasket, trapezoidal lower gasket respectively, rubber gasket is the circular ring structure of band trapezoidal groove, trapezoidal Upper gasket and trapezoidal lower gasket are the circular ring structure being with trapezoidal projection, and spring energy-storage assembly is formed 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 in the circular trapezoidal groove of the upper and lower both sides of rubber gasket respectively.
The underwater sealing that the underwater platform cable sealing device that the present invention relates to is connected with underwater platform external equipment cable for underwater platform penetrating cable in water.
During the application of underwater platform cable sealing device, successively compression end cap, spring energy-storage assembly, trapezoidal Upper gasket, rubber gasket and trapezoidal lower gasket are enclosed within one end of penetrating cable and equipment cable respectively, then penetrating cable put into seal casinghousing respectively with equipment cable and be connected, spinning compresses end cap extrusion spring energy storage component again, trapezoidal Upper gasket is extruded and rubber gasket carrys out jam-packed penetrating cable by spring energy-storage assembly, space between equipment cable and seal casinghousing, thus realize connecting underwater platform and the penetrating cable of external equipment and the connection of equipment cable seals.
The underwater platform cable sealing device that the present invention relates to, by with the rubber gasket of trapezium structure and upper lower gasket, adds transverse pressure, adds 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 increase 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.
