The invention relates to a cooling mechanism for an inner-slip-ring motor, which is particularly used for cooling the inner-slip-ring motor and belongs to the technical field of motors. The cooling mechanism comprises a brush holder, a slip ring, a motor shell, a motor cooler, an air-collecting hood, a shutter and a baffle, wherein the brush holder is installed in the motor shell, the outer ring of the brush holder is connected with the slip ring, the motor cooler is fixed on the motor shell, and the motor cooler is connected with the air-collecting hood. The air-collecting hood is fixed on the motor shell, and the lower side of the air-collecting hood faces the slip ring. The baffle is fixed on the bottom of the inner side of the motor shell, and the shutter is connected to the motor shell at the both sides of the baffle through bolts. The cooling mechanism disclosed by the invention is simple, compact and reasonable in structure; the cooling effect is good, and the use range of the inner-slip-ring motor is improved; and carbon powder in the motor can be periodically cleaned.

Description

The cooling body of interior slip ring motor
Technical field
The present invention relates to a kind of cooling body of interior slip ring motor, the cooling of slip ring motor belongs to the motor technology field in specifically being used for.
Background technology
Motor is a kind of equipment that converts electric energy to mechanical energy.It is to utilize hot-wire coil (stator winding just) to produce rotating magnetic field and act on the closed aluminium frame of rotor squirrel-cage formula to form magnetoelectricity power rotation torque.Motor is by using the power supply difference to be divided into DC motor and alternating current motor, and the motor major part in the electric power system is an alternating current machine, can be synchronous machine or asynchronous machine (motor stator magnetic field rotating speed and rotor rotation rotating speed do not keep same leg speed).Motor mainly is made up of stator and rotor, and electrified wire stressed travel direction in magnetic field is relevant with magnetic induction line (magnetic direction) direction with the sense of current.The motor operation principle be magnetic field to the stressed effect of electric current, motor is rotated.Advantages such as that threephase asynchronous has is simple in structure, be easy to control, efficient is high, cost is low and power is big are widely used in the modern various plant equipment.
All the time, the environment for use of motor is very complicated, all uses motor like traditional industries such as colliery, mine, cement.General cement industry uses motor more.And the slip ring structure of motor generally is designed to outer slip ring, slip ring degree of protection IP23.The motor size of outer slip ring structure is longer relatively, and the local influence little in some spaces used.In addition, some special operation condition need motor is made twin shaft and is stretched action, and conveniently to connect auxilliary biography equipment, this moment, motor need be made interior slip ring structure.The slip ring structure is in the slip ring chamber, to be provided with fan in the motor routine, wind path in forming, and difficult discharge such as dust is prone to cause the slip ring short circuit, blows out even burns out, and directly influences the production of whole production streamline.For this reason, interior slip-ring motor needs a kind of new cooling body to satisfy some special environments for use.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point, thus provide a kind of in the cooling body of slip ring motor, simple in structure, good cooling results has improved the scope of application of interior slip ring motor.
According to technical scheme provided by the invention; The cooling body of interior slip ring motor comprises brush holder support, slip ring and motor casing; Brush holder support is installed in the motor casing, and the brush holder support outer ring connects slip ring, it is characterized in that: also comprise cooler of electric motor, wind-collecting cover, shutter and baffle plate; Cooler of electric motor is fixed on the motor casing, and cooler of electric motor is connected with wind-collecting cover.Said wind-collecting cover is fixed on the motor casing, and the wind-collecting cover downside is to slip ring.Said motor casing inside bottom fixed dam connects shutter through bolt on the motor housing of baffle plate both sides.
Said wind-collecting cover is up big and down small funnel-shaped structure.Said baffle plate is a herringbone.
Compared with present technology the present invention has the following advantages: the present invention is simple, compact and reasonable for structure; Good cooling results has improved the scope of application of interior slip ring motor; The motor internal carbon dust can periodic cleaning.

Embodiment
Following the present invention will combine the embodiment in the accompanying drawing to further describe:
Shown in Fig. 1 ~ 2, the present invention mainly comprises cooler of electric motor 1, wind-collecting cover 2, brush holder support 3, slip ring 4, shutter 5, baffle plate 6 and motor casing 7.
Brush holder support 3 is installed in the motor casing 7, and brush holder support 3 outer rings connect slip ring 4.Cooler of electric motor 1 is fixed on the motor casing 7, and cooler of electric motor 1 is connected with wind-collecting cover 2.Said wind-collecting cover 2 is fixed on the motor casing 7, and wind-collecting cover 2 is up big and down small funnel-shaped structure, and wind-collecting cover 2 downsides are to slip ring 4.Said motor casing 7 inside bottom are fixed lambdoid baffle plate 6, connect shutter 5 through bolt on the motor housing 7 of baffle plate 6 both sides.
Operation principle of the present invention is: during machine operation, draw cold wind through cooler of electric motor 1 and get into wind-collecting cover 2.Wind-collecting cover 2 is a funnel-shaped structure, can concentrate compression to cold wind, and cold wind after the compression gets into slip ring 4 the insides, directly slip ring 4 is taken away because of fricative heat, blows out from the shutter 5 of bottom.Remain like this that hot blast goes out, cold wind advances, reduced the temperature rise in the slip ring chamber effectively.Motor casing 7 bottom fixed dams 6, baffle plate 6 are the low herringbone structures in middle high two ends, play guides wind to moving towards with carbon dust.The carbon dust that slip ring 4 is discharged, only need regularly be opened shutter 5 and clear up and get final product shutter 5 other accumulations along baffle plate 6, unsafe factor such as can eliminate effectively that the slip ring that causes the carbon dust accumulation to cause because of the untimely cleaning of carbon dust is blown out.
Above-described only is the preferred implementation of patent of the present invention, and patent of the present invention is not limited to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite of spirit that does not break away from patent of the present invention and design, all should think to be included within the protection range of patent of the present invention.
