And need spring top pressure；Two is that abrasion is very fast, needs often to change carbon brush；Three is to there is hidden danger,
The carbon dust that carbon brush abrasion produces easily causes short circuit.
Summary of the invention
It is an object of the invention to: a kind of underwater elastic wire collector ring of offer, simple in construction, wear-resistant,
Safe and reliable.
For achieving the above object, the present invention can take following technical proposals:
The new a kind of underwater elastic wire collector ring of this practicality, including the insulation fixture block being arranged on stator and setting
Becket on rotor, described becket is connected with the wire on rotor, solid on described insulation fixture block
Being provided with the resilient tinsel of tool, this tinsel one side pressure touches the outer round surface in described becket, another
One end is connected with the wire on stator, and described elater collector ring is arranged under water in numerical control nozzle, described
The lower end of stator constitutes water-stop by the lower oil sealing being arranged on stator bottom end cover with rotor, stator
Upper end constitutes water-stop by the upper oil sealing being arranged on stator upper end cover with rotor.
Described insulation fixture block is provided with the through hole of inclination, and described tinsel is arranged in this inclined via-hole.
Described insulation fixture block is strip, axially disposed, and described inclined via-hole has multiple and vertically
It is distributed on insulation fixture block.
The cross section of insulation fixture block is circular arc.
Described insulation fixture block at least two, is distributed on stator inner periphery.
Being provided with many one metal wires in each described inclined via-hole, these many one metal wires constitute wire bundle,
Separated by the insulation ring plate being fixedly arranged on rotor between adjacent described wire bundle.
Lug it is provided with on the edge of this stator bottom end cover between stator and stator bottom end cover, described convex
Ear is provided with wire perforation, and the inner port capping bored a hole at described wire has one piece of cover plate, described cover plate
Inner side be welded with inner lead, this inner lead is the wire on described stator, outside cover plate
It is corresponding even by the conductor on cover plate that side is welded with outer lead, described inner lead and outer lead
Connect, in the wire perforation outside described cover plate, be filled with fluid sealant.
Described cover plate is printed substrate, and the conductor on described cover plate is the track on printed substrate
Road, this printed substrate is fixed in the inner port of wire perforation by fixed screw, described inner port
Place is provided with groove, and described printed substrate is embedded in this groove.
Compared with prior art the invention has the beneficial effects as follows: owing to using technique scheme, in institute
Stating and be installed with the resilient tinsel of tool on insulation fixture block, this tinsel one side pressure is touched in described becket
Outer round surface, the other end be connected with the wire on stator, this structure, than traditional carbon brush structure
Simply, and tinsel wearability is more preferable, and service life is long, safe and reliable.
Further provide the benefit that: traditional conductor leading Sealing Technology, the most all use inside
Cable welding or hinge joint, wrap up in insulating tape or heat-shrink tube, and cable sealing O passes through pressure
Make it squeeze swollen, by cable sheath compress seal, this structure, can accomplish waterproof action really,
But sealing structure inner chamber and external environment condition still communicate, because inside and outside portion cable multiple conducting wires
And the internal many bare copper wires of each wire or UNICOM, this stops for working for a moment for a moment
For sealing inside configuration electrical equipment, it is in the state of a cold heat, it is easy to condensation can be internally formed
Phenomenon, makes sealing inside configuration produce aqueous vapor and causes the device damage such as electrical equipment.And cable connector because
It is stained with aqueous vapor and the reason being energized, through oxide etch after a while, also can produce oxidation open circuit
Phenomenon, causes the device damage sealed in structure normally to use.The principle that condensation produces: with water
As a example by lower motor and light fixture.Motor or light fixture are when indoor assembling completes, and in inner chamber, relative humidity exists
40-50%, when motor runs, can produce high temperature in inner space, and air expansion pressure becomes big, because of
For equilibrium principle, the gas pressure in cavity increases, needs to overflow outward to reach internal and external pressure balance,
At this moment, because inside and outside portion cable multiple conducting wires and the internal many bare copper wires of each wire still
UNICOM, gas will overflow, and inner and outer air pressure is until balance, simultaneously as interior cavity temperature raises, empty
The relative humidity of gas declines, and such as drops to 10%, in order to be able to reach inside and outside wetting balance, at rubber
Seal the edge of water, the place of cable adapter, very fast (at once can become dry) that water can evaporate,
Increase the absolute magnitude of steam, make the relative humidity of intracavity and the external world can reach balance.When light fixture or
Motor does not runs, to such an extent as to cavity temperature cooling, a negative pressure, then extraneous tide can be formed at intracavity
Wet air flows in cavity, and the relative humidity balance that original intracavity reaches because temperature raises
State, because temperature cooling is broken, cooling makes intracavity relative humidity become suddenly big, saturated when exceeding
Time or encounter colder material, just there is condensation.The present invention is between stator and stator bottom end cover
The edge of this stator bottom end cover is provided with lug, and described lug is provided with wire perforation, at described wire
The inner port capping of perforation has one piece of cover plate, and the inner side of described cover plate is welded with inner lead, inside this
Wire is the wire on described stator, and the outside of cover plate is welded with outer lead, and described inside is led
Line connects by the conductor on cover plate is corresponding with outer lead, in the wire perforation outside described cover plate
It is filled with fluid sealant, this structure, fluid sealant can not only be utilized wire aperture seal, Er Qieyou
Being to be connected by the conductor correspondence on cover plate in inside and outside portion cable, this allows for inside and outside portion wire
Multiple conducting wires and the internal many bare copper wires of wire are the most separated by a seal, make closed structure inner chamber and the external world
Completely cutting off completely, this has just stopped the circulation of closed structure inner air and outer air, and inner air and outer air can not produce circulation,
Steam cannot propagate into closed structure inner chamber, and the dew condensation phenomenon within closed structure just cannot be formed,
Good sealing effect, lasting stability.And achieve and arrange with stator bottom end cover narrow space at stator
The sealing structure of conductor leading, simple in construction, compact, occupy-place is little, good sealing effect, solves sound
The technical barrier that happy fountain system conductor leading under water seals.
