Description

The waterproof seal of diving generator cable
Technical field
The present invention relates to submersible motor field, and in particular to a kind of waterproof sealing dress of diving generator cable Put.
Background technology
Submersible pump includes submersible sewage pump, submersible axial-flow pump and submersible type mixed-flow pump, is a kind of wide The general fluid transmission machinery for using.It is that motor enters with the major failure of the submersible motor of submersible pump adapted Water, lift more and more higher and the increasing of diving depth with pump, the possibility of motor entering water is also increasingly Greatly.And cable is also more and more stricter with the seal request of submersible motor junction.And in the prior art, dive Hydroelectric machine uses YZ or YCW type rubber sleeve waterproof flexible cables, and cable periphery is cased with incoming seal circle, so Incoming seal circle is compressed with cable feedthrough afterwards, is sealed by incoming seal circle compressive deformation;This sealing Mode sealing effectiveness is bad, once being revealed between cable failure or cable and incoming seal, water will enter Terminal box chamber, causes motor entering water or makes moist.Furthermore in order to improve sealing property, typically in cable seal In connection more firmly, cause repair demolition inconvenient;Lack between cable core and motor internal simultaneously Weary corresponding safeguard measure, when the protective layer of cable is damaged, because of the reason of Underwater Pressure, water can enter To motor coil, the decreasing insulating of motor causes burn-down of electric motor or electric leakage, easily causes accident, Larger economic loss is brought to enterprise.
The content of the invention
It is an object of the invention to provide a kind of waterproof seal of diving generator cable, with good close Envelope effect, it is solid and reliable, and be easily installed and dismantle, to solve the electricity of submersible motor in the prior art Cable seals insecure technical problem.
In order to solve the above technical problems, the technical solution adopted by the present invention is:A kind of diving generator cable Waterproof seal, including cable core, two sections of cables and for connect two sections of cable connectors of cable, Also include transition outer barrel, the transition outer barrel is set on the cable connector, its lower end be used for it is close Covered on the motor for sealing motor and be fixedly connected, cable stretches out from the upper end of transition outer barrel, the transition outer barrel Upper end is additionally provided with stepped hole, the aperture of the aperture less than cable connector of the stepped hole;Two sections of electricity A metallic conductor is provided between the opposite end face of cable, the periphery of the metallic conductor, metal are led Electric body is surrounded with the periphery of two sections of described junctions of cable Insulating heat shrink, and the metal is led Electric body and Insulating heat shrink are respectively positioned in cable connector.
Preferably, the cable seal structure also includes cable connector, and the cable connector is located at transition outer barrel Upper end, and cable connector is provided with perforation, and cable may pass through the perforation on cable connector.
Preferably, outside one layer of gum cover of parcel of the cable, sealing resin in the space in the gum cover, The resin is combined with corresponding gum cover and cable core and encapsulates corresponding cable core.
Preferably, it is connected through a screw thread between being covered on the transition outer barrel and motor, and uses the first sealing ring Sealing.It is connected through a screw thread between the cable connector and transition outer barrel, and is sealed with the second sealing ring. Also, the sealed clamping set of elasticity is additionally provided between the perforation of the cable connector and the cable, so that Reach the effect of clamping cables and sealing.
Used as optimal technical scheme, the metallic conductor is made up of columned solid copper sleeve.
The invention has the advantages that:
1st, present invention employs multi-sealed safeguard measure, ensure that the cable of submersible motor under water Using when sealing, with good water resistance and insulating properties.Wherein cable connector can rise To fixed cable, the effect for preventing cable from loosening;And transition outer barrel provides another layer of protection, effectively protect The sealing of device is demonstrate,proved, and has been easily installed and is dismantled.
2nd, the present invention is isolated two sections of cables using metallic conductor, conductor and metallic conduction in cable Body is isolated by Insulating heat shrink, can play good insulating effect;Wrapped up by the outside of cable One layer of gum cover, sealing resin in the space in gum cover realizes the sealing to cable core.Insulation is had concurrently Performance and barrier propterty, the sealing property of Reliable guarantee cable.
