Abstract
The utility model discloses a low-speed conductive slip ring device and belongs to the technical field of ship manufacture. The low-speed conductive slip ring device comprises a collecting ring and an electric brush connected with the collecting ring, wherein the electric brush is a metal electric brush, and the rated current of the metal electric brush is 600A. The rotation speed of the collecting ring is 0.0003 m/s-0.0006 m/s. The collecting ring is made of a brass material. The electric brush is made of a silver alloy material. According to the low-speed conductive slip ring device, the silver alloy electric brush is adopted, and when the collecting ring of the conductive slip ring device rotates, the contact face of the electric brush and the collecting ring has low abradability, micro-arcs are not produced at the contact position of the electric brush and the collecting ring, and the surface damage of the collecting ring is avoided. The low-speed conductive slip ring device is low in failure rate and easy to maintain.
Description
Technical field
The utility model relates to shipbuilding technical field, especially a kind of for giving the low speed conducting slip ring device of the feed cable folding and unfolding of the ship power supply that rests in harbour.
Background technology
In shipping industry, the boats and ships of having manufactured on the coast can be transferred to the operation of carrying out other operation in water conventionally, need power electric, and that the electric power system of boats and ships itself does not also have is perfect, this just need to power to it from stube cable on the bank, and can there is the problem of the high end of water level in the rivers of natural conditions, when water level is high, to receive cable, when water level is low, want payout; What folding and unfolding cable was used is reel, because cable is connected on reel, when reel 360 degree continuous rotation, will run into the problem of cable winding; So needing an electric rotary connector is conducting slip ring, conducting slip ring is the rotary connector of transmission power electric and signal, due to the liter of water level with to fall be a process slowly, the folding and unfolding speed of cable is also relatively slow, so normal employing is low speed conducting slip ring device in shipbuilding industry, low speed conducting slip ring device comprises collector ring and the brush being attached thereto; The collector ring of low speed conducting slip ring device adopts brass material, and brush adopts copper carbon ink material.This low speed conducting slip ring device can there are the following problems: because the number of times of fluctuation in stage within a year is few, the cable drum most of the time does not need folding and unfolding cable, cause brush to be still in for a long time the same position of collector ring, under this state, 600 peaces large electric current is doubly for a long time by low speed conducting slip ring device, and peak current can reach more than 1,000 ampere.The contact position of brush and collector ring will produce micro-electric arc like this, make to produce indenture on the contact-making surface of collector ring and brush, when receipts or payout, can make again the another location of collector ring and brush contact surface produce indenture, through accumulating over a long period, the contact-making surface of brush and collector ring makes collector ring surface irregularity because of arcing, and then melt down, cause low speed conducting slip ring plant failure rate high, difficult maintenance.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of low speed conducting slip ring device, this low speed conducting slip ring device can solve, during conducting slip ring device transfixion, the contact position of brush and collector ring produces micro-electric arc, cause collector ring surface irregularity, and then melt down, the low speed conducting slip ring plant failure rate causing is high, the difficult problem of safeguarding.
In order to address the above problem, the technical scheme that the utility model adopts is: this low speed conducting slip ring device, and including collector ring is metallic brush with brush described in the brush being attached thereto, the rated current of described metallic brush is 600A; The velocity of rotation of described collector ring is 0.0003m/s～0.0006m/s.
In the technical scheme of above-mentioned low speed conducting slip ring device, technical scheme can also be more specifically: described collector ring is made by brass material.
Further: described brush is that silver alloy is made.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, the silver alloy brush that the utility model adopts, when conducting slip ring device collector ring rotates, the contact surface abrasion degree of brush and collector ring is little, and the contact position of brush and collector ring can not produce micro-electric arc, has avoided the damage on collector ring surface.
2, the utility model failure rate is low, easily safeguards.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Embodiment mono-
Low speed conducting slip ring device shown in Fig. 1, the brush 1 that includes collector ring 2 and be attached thereto, brush 1 is silver alloy brush, the rated current of silver alloy brush is 600A; Collector ring 2 is made by brass material, and the velocity of rotation of collector ring 2 is 0.0003m/s.Low speed conducting slip ring device is arranged on a side of reel, its collector ring 2 is arranged on the rotation axis of reel, during work, when reel rotates receipts or payout, the corresponding synchronized rotation of collector ring 2, avoid connected cable winding, the silver alloy brush being connected with collector ring 2 reaches boats and ships electrical control cubicles by power electric simultaneously, for the needs of marine vessel power.The silver alloy brush that the utility model adopts, when the collector ring 2 of conducting slip ring device rotates, brush 1 is little with the contact surface abrasion degree of collector ring 2, and brush 1 can not produce micro-electric arc with the contact position of collector ring 2, has avoided the damage on collector ring 2 surfaces, failure rate is low, easily safeguards.
Embodiment bis-
The velocity of rotation of collector ring is 0.0006m/s.All the other are all identical with embodiment mono-.
