[0002] A hydro-turbine generator is a generator that can convert water potential energy into electrical energy. Carbon brushes are needed inside the generator. Carbon dust will appear during the use of the carbon brushes. In this case, a carbon dust pollution prevention device will be used to clean the carbon dust to reduce the impact of carbon dust on the hydro-turbine generator.

[0003] However, the existing anti-carbon dust pollution device for hydro-generator sets still has certain use defects during use. The existing anti-carbon dust pollution device requires additional dust collection equipment, the overall structure is complicated, and the dust collection device and collection device are expensive. In addition, supporting control lines and pipelines are required, which brings additional burdens to daily maintenance work.

[0004] Patent application announcement number CN219678279U discloses a device for preventing carbon powder pollution for a vertical hydro-turbine generator set. The carbon powder generated by the friction between the contact surface of the carbon brush and the collector ring falls on the upper surface of the multi-layer filter cotton after free fall.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] In a specific embodiment, Figure 1-Figure 2 As shown, the basic working process of the device is disclosed;

[0030] The main shaft 1 and one end of the main shaft 1 are fixedly mounted with a collector ring 2;

[0031] A carbon brush 3 is fixedly mounted on one end of the main shaft 1 away from the collector ring 2. A mounting frame 4 is fixedly mounted on the outside of the main shaft 1, and a feed cylinder 5 is fixedly mounted inside the mounting frame 4. A collection cover 6 is fixedly mounted on the upper end of the feed cylinder 5, and the collection cover 6 is located at the lower end of the mounting frame 4. A receiving cylinder 7 is sleeved on the lower end of the feed cylinder 5.

[0032] A rotating rod 9 is rotatably installed inside the feeding cylinder 5, and a cleaning rod 10 is fixedly installed on the upper end of the rotating rod 9, and the cleaning rod 10 is tightly fitted with the inner surface of the collecting cover 6. At the same time, a limiting frame 8 is fixedly installed on the outer side of the feeding cylinder 5.

[0033] When using the carbon powder collecting device for preventing carbon powder pollution of the hydro-turbine generator set, the carbon blocks inside the carbon brush 3 will fall into powder, and the carbon powder needs to be processed. In this process, the carbon powder dropped by the carbon brush 3 needs to be collected by the feeding tube 5, and after the feeding tube 5 collects the carbon powder, the carbon powder will be transported to the inside of the receiving tube 7 through the feeding tube 5. At this point, the carbon powder collection process of the device is completed, which can effectively reduce the impact of carbon powder.

[0034] In one specific embodiment, Figure 1-Figure 5 As shown, the process of collecting and cleaning the carbon dust is disclosed;

[0035] A fixed shaft 11 is fixedly mounted on the outer side of the rotating rod 9, and an elastic rod 12 is fixedly mounted on the end of the fixed shaft 11 away from the rotating rod 9, and a striking ball head 13 is fixedly mounted on the end of the elastic rod 12 close to the feeding cylinder 5;

[0036] A fixing block 14 is fixedly installed inside the feeding cylinder 5, and the fixing block 14 is arranged corresponding to the striking ball head 13, and the center of the striking ball head 13 is located at the center upper end of the fixing block 14;

[0037] The lower end of the rotating rod 9 is fixedly mounted with a bevel gear 2 16, and the lower end of the rotating rod 9 is rotatably mounted with a protective cover 15, and the protective cover 15 is located outside the bevel gear 2 16;

[0038] A rotating shaft 17 is rotatably mounted inside the feed barrel 5, and a bevel gear 18 is fixedly mounted on one end of the rotating shaft 17 close to the protective cover 15. The bevel gear 18 is located inside the protective cover 15 and is meshed with the bevel gear 2 16.

[0039] A slave gear 19 is fixedly mounted on one end of the rotating shaft 17 away from the protective cover 15 , and the slave gear 19 is located outside the feeding cylinder 5 . A gear rod 20 is fixedly mounted on the upper end of the receiving cylinder 7 , and the gear rod 20 is meshed with the slave gear 19 .

[0040] When the device for preventing carbon dust pollution of the hydro-turbine generator set that can collect carbon dust is used, it is necessary to remove the receiving cylinder 7 from the outer side of the feeding cylinder 5 and clean the carbon dust inside the receiving cylinder 7. During the downward movement of the receiving cylinder 7, the receiving cylinder 7 drives the gear rod 20 to move downward synchronously, and the gear rod 20 drives the slave gear 19 to rotate during the downward movement, and the slave gear 19 drives the rotating shaft 17 to rotate synchronously, and the rotating shaft 17 drives the bevel gear 1 18 to rotate inside the protective cover 15, and the rotation of the bevel gear 1 18 drives the bevel gear 2 16 meshed with it to rotate, and the rotation of the bevel gear 2 16 drives the rotating rod 9 to rotate. At this time, the rotation of the rotating rod 9 drives the cleaning rod 10 to rotate inside the collecting cover 6, and the rotation of the cleaning rod 10 can clean the carbon dust adhered to the inside of the collecting cover 6, thereby ensuring the convenience of cleaning the carbon dust inside the collecting cover 6;

[0041] During the rotation of the rotating rod 9, the rotating rod 9 will synchronously drive the fixed shaft 11 and the elastic rod 12 to rotate, and the elastic rod 12 will drive the striking ball head 13 to rotate, and during the rotation of the striking ball head 13, it will contact the fixed block 14 and hit the fixed block 14, which will cause the feed barrel 5 and the collecting cover 6 to vibrate, avoiding the accumulation of carbon powder on the inner surfaces of the feed barrel 5 and the collecting cover 6, thereby ensuring the thoroughness of the carbon powder cleaning.

[0042] Based on the above embodiments, Figure 1 and Figure 6 As shown, the convenience of cleaning carbon powder of the device is disclosed;

[0043] A movement groove 21 is provided inside the upper end of the receiving cylinder 7, and a limit block 22 is slidably installed inside the movement groove 21, and a return spring 23 is fixedly installed on one end of the limit block 22 close to the movement groove 21. A limit groove 24 is provided on the outer side of the lower end of the feeding cylinder 5, and the limit groove 24 is engaged with the limit block 22.

[0044] When using the carbon powder pollution prevention device for the hydro-generator set capable of collecting carbon powder, the receiving tube 7 needs to be removed from the outside of the feeding tube 5. During this process, the receiving tube 7 needs to slide on the outside of the feeding tube 5. The movement of the receiving tube 7 will drive the limit block 22 to move synchronously.

[0045] During the movement of the limit block 22, it will be squeezed by the limit groove 24. After being squeezed, the limit block 22 will move toward the inside of the limit groove 24. During the movement of the limit block 22, the return spring 23 will be squeezed and the return spring 23 will contract. After the limit block 22 is separated from the limit groove 24, the feeding cylinder 5 can be separated from the receiving cylinder 7. At this time, the receiving cylinder 7 can be removed and the carbon powder inside the receiving cylinder 7 can be cleaned, which effectively improves the convenience of cleaning the carbon powder of the device and increases the overall practicality.
