Abstract
The utility model discloses a kind of fire-proof motor current collection assembly, comprise total adult, described total adult comprises brush mount component, conductive plate, dust settler and collector ring; Described brush mount component is secured by bolts on conductive plate; Described conductive plate is fixed together by fixed lever; And be arranged at inside total adult, and be arranged at the collector ring between conductive plate; Described total adult, while motor continuous rotation, transmits power supply from fixed position to position of rotation, avoids wire to cause in rotary course and sprains; Described collector ring arranged outside has dust settler; And be arranged at the big fan at collector ring top, and be arranged at the small fan bottom collector ring, make current collection assembly quick heat radiating.Fire-proof motor current collection assembly of the present utility model, structure is simple, and which solve electric machine temperature rise in prior art high, same volume power of motor is low, and cost is high, and motor internal does not have the present situation of depositing dust function.
Description
Technical field
The utility model relates to a kind of motor current collection assembly apparatus, is specifically related to a kind of fire-proof motor current collection assembly, belongs to electric machine assembly technical field.
Background technology
Fire-proof motor is a kind of a kind of motor that can use at combustible and explosive area, does not produce electric spark during operation.Fire-proof motor is mainly used in colliery, petroleum gas, petrochemical industry and chemical industry; In addition, be also widely used in the department such as weaving, metallurgy, gas, traffic, grain and oil processing, papermaking, medicine.Fire-proof motor, as main power-equipment, is generally used for driving pump, blower fan, compressor and other gearings etc.; Fire-proof motor mostly adopts flameproof enclosure, by flameproof enclosure, the explosive gas mixture of the electric part and surrounding that may produce spark, electric arc and dangerous temperature is separated; But this shell is not sealing, and explosive gas mixture around can enter motor internal by the gap, each several part composition surface of shell; Just may blast when contacting with Ignition sources such as the spark in shell, electric arc, dangerous high temperature, at this moment the flameproof enclosure of motor not only can not damage or be out of shape, and explosive flame or hot gases are when spreading out of by gap, composition surface, the explosive gas mixture of surrounding of can not igniting; Above-mentioned is only design from housing, but it can not solve its inner easily problem such as short circuit, the too high blast of temperature of machine operation process.
Utility model content
(1) technical problem that will solve
For solving the problem, the utility model proposes a kind of fire-proof motor current collection assembly, which solve electric machine temperature rise in prior art high, same volume power of motor is low, and cost is high, and motor internal does not have the present situation of depositing dust function.
(2) technical scheme
Fire-proof motor current collection assembly of the present utility model, comprises total adult, and described total adult comprises brush mount component, conductive plate, dust settler and collector ring; Described brush mount component is secured by bolts on conductive plate; Described conductive plate is fixed together by fixed lever; And be arranged at inside total adult, and be arranged at the collector ring between conductive plate; Described total adult, while motor continuous rotation, transmits power supply from fixed position to position of rotation, avoids wire to cause in rotary course and sprains; Described collector ring arranged outside has dust settler; And be arranged at the big fan at collector ring top, and be arranged at the small fan bottom collector ring, make current collection assembly quick heat radiating.
As preferred embodiment, described collector ring side opening is provided with multiple aperture, and loop surface offers helicla flute; When collector ring is rotated, thermal diffusivity is good.
As preferred embodiment, in the middle of each ring of described collector ring, be provided with a straight trough; Be equivalent to be cut into two rings, when collector ring is rotated, thermal diffusivity is good, increases power of motor simultaneously.
As preferred embodiment, described big fan and small fan directly and collector ring install; When collector ring rotates, can directly to electric motor temperature reduction, blower fan that need not be independent to electric motor temperature reduction, thus can reduce costs.
As preferred embodiment, described dust settler is fixed by support bar, and dust settler covers collector ring; Filter the carbon dust produced in brush mount component and collector ring friction process, solve motor internal cause carbon dust too many, electric equipment compartment is creepage and burn out motor problem.
(3) beneficial effect
Compared with prior art, fire-proof motor current collection assembly of the present utility model, structure is simple, and which solve electric machine temperature rise in prior art high, same volume power of motor is low, and cost is high, and motor internal does not have the present situation of depositing dust function.
