Description
Technical field
The present invention relates to a kind of underwater propulsion motor sealing structures.Belong to motor seal field.
Background technique
For general existing middle-size and small-size submersible machine, motor cable is usually to pass through the sealing devices such as stuffing-box to clamp electricity
Cable is sealed, and can prevent water from entering motor.But for Large Underwater propulsion electric machine, current of electric reaches several kiloamperes,
Motor cable is three-core cable, if having a barotropic gas inside motor, gas can be by the slot leakage between three cores, in motor
Portion is not able to maintain normal pressure.
Due to environmental requirement, ship cannot be leaked in ocean using underwater propulsion motor bearing lubrication grease, therefore axis
Bearing lubrication oil sewage draining exit needs to keep positive pressure inside motor, the sump oil inside motor could be passed through function all inside motor
Pipeline excludes outside motor.Separately for underwater propulsion motor, motor generation contingency will lead to external water and drain to motor
Inside, water leakage inside will affect the safety of ship's navigation, and positive pressure is kept motor can be discharged in the water inside motor inside motor.
Summary of the invention
It is an object of the invention to propose a kind of sealing structure suitable for underwater propulsion motor, for solving large-current electric
Machine three-core cable directly leads out the problem of causing motor gas leakage, keeps the positive pressure inside motor, be discharged the sump oil inside motor and
Water, while being able to satisfy motor high current input, the requirement that signal is drawn, function pipeline accesses.
To meet above-mentioned purpose, the technical scheme is that a kind of underwater propulsion motor sealing structure, including insulation are close
Sealing plate, insulation busbar, sealing ring, external screw thread pipeline, aviation plug, motor cable, motor signal line, the function pipe in motor
Sealing ring is placed in the groove of the insulated enclosure back, and is tightly connected by bolt and motor support plate in road；It is described
Square seal ring is placed in the groove of insulation busbar, and is tightly connected by bolt and insulated enclosure plate；The male-pipe
Road is installed in the internal thread through hole of insulated enclosure plate after applying sealant, prevents external screw thread pipeline and insulated enclosure by sealant
Gas leakage between the internal screw thread of plate；The aviation plug is installed on insulated enclosure plate by bolt, by close on aviation plug
Seal prevents the gas leakage between insulated enclosure plate and aviation plug.
Further, the motor cable is accessed from one end of insulation busbar, and the other end picks out.
Further, the motor signal line is accessed from the aviation plug one end being installed on insulated enclosure plate, another termination
Out.
Further, the function pipeline in the motor is picked out with the internal screw thread pipeline being installed on insulated enclosure plate.
Further, the motor cable, signal wire, function pipeline are concentrated by insulated enclosure plate and are drawn, and pass through function pipe
It is with air pressure capable of being increased inside road direction motor, the normal pressure inside motor can be kept, the water inside motor will be drained to and oil passes through function pipe
Road discharge.
Beneficial effects of the present invention:
Motor outgoing cable is mounted on the insulation busbar of this sealing structure, signal wire is connect in this sealing structure
On aviation plug, function pipeline is connect on the male-pipe road of this sealing structure, by function pipeline to aerating inside motor
It presses, positive pressure can be kept inside motor, solve motor air pressure inside and protected from motor inside the case where motor cable gas leakage, is met
The requirement of positive pressure is held, while meeting the requirement of motor high current access, signal access, the access of function pipeline.

Specific embodiment
The invention will be further described with embodiment with reference to the accompanying drawing.
As shown in Figures 1 to 5, a kind of underwater propulsion motor sealing structure, including edge sealing plate 3, insulation busbar 1, close
Seal 4, external screw thread pipeline 6, aviation plug 5, motor cable, motor signal line, the function pipeline in motor.It will circle sealing ring 4
It is placed in the groove of insulated enclosure plate 3, then insulated enclosure plate 3 is installed in the support plate of motor, circle sealing ring 4 can be to prevent
Only gas leakage between insulated enclosure plate and motor support plate.Square seal ring 2 is placed in the groove of insulation busbar 1, then will
Insulation busbar 1 be installed on insulated enclosure plate 3, square seal ring 2 can prevent insulation busbar 1 and insulated enclosure plate 3 it
Between gas leakage.Will external screw thread pipeline 6 apply sealant after be installed in the internal thread through hole of insulated enclosure plate 3, sealant can be to prevent
The only gas leakage between 3 internal screw thread of external screw thread pipeline 6 and insulated enclosure plate.It is close that aviation plug 5 containing sealing ring is installed on insulation
On sealing plate 3, the sealing ring on aviation plug 5 can prevent the gas leakage between insulated enclosure plate 3 and aviation plug 5.Motor cable
Insulation busbar 1 can be accessed, then power supply system is accessed by insulation 1 other end of busbar.Function pipeline is by being mounted on absolutely
External screw thread pipeline 6 on edge sealing plate is forwarded in motor.Motor signal line is inserted by the aviation being mounted on insulated enclosure plate 1
First 5 draw.
Sealing structure of the present invention can keep the positive pressure inside motor, sump oil and water inside motor be discharged, while can be full
Sufficient motor high current input, the requirement that signal is drawn, function pipeline accesses.
