Detailed Description

The utility model will be further described with reference to specific examples and figures.

The utility model provides a detachable generator carbon brush sweeping dust collecting device, which comprises a dust collecting device 1, an air inlet main pipe 2 and a dust collector 3, wherein one end of the dust collecting device is correspondingly and detachably connected with a ventilation opening of a hood of a generator 4, for example: magnetic connection, threaded connection, etc. The other end of the dust collection device 1 is connected with an inlet joint 5 on a corresponding air inlet main pipe 2, and the outlet of the air inlet main pipe 2 is connected with a dust collector 3 through a pipe.

The air inlet main pipe 2 can be a corrugated pipe, a phi 50 plastic corrugated pipe is adopted, the dust collecting device 1 can be a dust collecting bag and a dust collecting box, the air inlet main pipe is made of nylon cloth, the inlet joint 5 can be a three-way joint, and a plastic three-way quick connector matched with the corrugated pipe is adopted, so that the air inlet main pipe is convenient to disassemble and assemble, and a plurality of air inlet main pipes can be installed on a pipeline.

The utility model adopts the magnetic dust collection device to be arranged at the ventilation opening (the magnetic dust collection device is convenient to disassemble and assemble) of the generator hood, the tail part of the dust collection box is connected with a dust collector pipe by adopting a corrugated pipe, and 1 ventilation opening is reserved for air supply.

As a further preferred option, the vacuum cleaner air outlet is connected to the air supply outlet by an air supply pipe 6, and the vacuum cleaner air outlet is detachably connected to the air supply outlet. For example: magnetic connection, threaded connection, etc. The air supply pipe 6 is a bellows. The air outlet of the dust collector is connected with the reserved 1 ventilation opening to achieve the purpose of air supply, and compressed air can be used for air supply at the air supply opening. If only used in purging, compressed air is used for purging, and the air outlet of the dust collector is not connected.

If the long-term operation is required to meet the automatic purpose, the dust collector can be controlled by using the unit LCU cabinet as shown in fig. 1, and the dust collector is automatically started when the unit is started, so that air circulation is performed, and the purpose of collecting carbon brush dust is met. The dust collector automatically stops when the machine unit is stopped.

According to the utility model, the dust collection device is arranged at the ventilation opening of the generator cover, and a dust collector is used for collecting dust, so that dust emission phenomenon caused by re-sweeping of carbon powder of the collector ring is prevented.
