Description

Technical Field

[0001] The invention relates to the technical field of generators, and in particular to a carbon powder collecting and cleaning device for a turbine collector ring. Background Art

[0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. It belongs to the turbine machinery in fluid machinery. The collector ring is also called a conductive ring, slip ring, collector ring, and collector ring. It can be used in any electromechanical system that requires continuous rotation and needs to transmit power and signals from a fixed position to a rotating position. The material of the collector ring requires high mechanical strength and is a good conductor of electricity. It must also be corrosion-resistant. When it comes into sliding contact with the brush, it must have wear resistance and stable sliding contact characteristics. Carbon brushes are also called brushes. As a sliding contact part, they are widely used in many electrical equipment. Carbon brushes are devices that transmit energy or signals between the fixed part and the rotating part of an electric motor or generator or other rotating machinery. It is generally made of pure carbon and a coagulant. It is generally a square in shape and is stuck on a metal bracket. There is a spring inside that presses it tightly on the shaft. When the motor rotates, the electrical energy is transmitted to the coil through the commutator. Because its main component is carbon, it is called a carbon brush. It is easy to wear and should be regularly maintained and replaced, and carbon deposits should be cleaned.

[0003] In the prior art, conformable felt is usually used to adsorb carbon powder, but dust adsorbed on the surface of conformable felt will accumulate. If not handled in time, the conformable felt will lose the effect of adsorbing dust. Based on these problems, Chinese patent CN215031509U discloses a carbon powder collection and cleaning device for a turbine collector ring, which reduces the pollution of the unit to carbon powder by the adsorption effect of conformable felt, cleans the carbon powder adsorbed by the conformable felt by a cleaning device to ensure the adsorption effect of the conformable felt, stores carbon powder in a collection box to reduce the number of times the staff cleans the carbon powder, and uses threaded connections and sockets between devices for easy disassembly and replacement. The device uses a rotating brush to clean the carbon powder adsorbed on the surface of the conformable felt, but in this process, the carbon powder that has left the surface of the conformable felt can easily float up again, causing pollution to the unit again, so the structure still has disadvantages during use.

[0023] See also Figure 1 , Figure 2 and Figure 3A slide bar 12 is fixed to the bottom of the conformable felt 8, a collar 13 slidably connected to the slide bar 12 is provided on the load-bearing plate 7, and a handle 14 is provided on the conformable felt 8. The handle 14 is pulled to slide forward and backward on the collar 13 in cooperation with the slide bar 12 to complete the pulling and pulling of the conformable felt 8 and improve the stability of the conformable felt 8 during the sliding process. When the conformable felt 8 is pulled out, the bottom surface of the cleaning brush 9 contacts the top surface of the conformable felt 8, thereby scraping off the carbon powder on the conformable felt 8. The provided handle 14 facilitates the staff to pull the conformable felt 8.

[0024] See also Figure 1 , Figure 2 and Figure 3 The cleaning brush 9 is fixed to the load-bearing plate 7 through a connecting plate 15 and a threaded rod 16. The lower end of the connecting plate 15 is fixedly connected to the upper end of the cleaning brush 9. When installing the cleaning brush 9, only the connecting plate 15 needs to be installed on the threaded rod 16, and then the nut 17 is tightened to fix it, and the installation of the cleaning brush 9 can be completed.

[0025] See also Figure 1 and Figure 4 The rear end of the inner wall of the side shell 5 is fixedly connected with a back plate 18 , and a dustproof ventilation net 19 is penetrated through the back plate 18 .

[0026] See also Figure 1 and Figure 4 The top of the frame 5 is located above the back plate 18 and is fixedly connected to a side plate 20. The side plate 20 has the same length as the top surface of the side shell 5. An inverted U-shaped sliding frame 21 is provided on the inner side of the side plate 20. A baffle 22 is slidably connected to the inner wall of the inverted U-shaped sliding frame 21. The bottom ends of the baffle 22 slide closely against the top surface of the frame 5.

[0027] See also Figure 1 and Figure 5 The dust collection assembly includes a dust collector 23 which is arranged on both sides of the side shell 5 , a recovery tank 24 is installed at the end of the dust collector 23 , and a filter screen 25 is arranged at the end of the recovery tank 24 .

The two groups of cleaning and recycling components can work separately without interfering with each other.

[0029] Working principle: when the turbine collector ring is working, it will produce carbon powder that falls downward, and then the carbon powder falls onto the conformable felt 8, which can absorb the carbon powder. When the handle 14 on the conformable felt 8 is pulled, the top surface of the conformable felt 8 can be close to the bottom surface of the cleaning brush 9, so that the carbon powder attached to the conformable felt 8 can be removed, and the removed carbon powder will directly fall into the recycling box 6 due to the force of gravity; a dust-proof ventilation net 19 is arranged on the back plate 18 to make the air circulation between the inside and the outside smoother, and the dust-proof ventilation net 19 can intercept the carbon powder to prevent the carbon powder from falling out; when the recycling box 6 needs to be replaced, the baffle 22 is pushed so that the bottom surface of the baffle 22 is close to the top surface of the front plate 10, the back plate 18 and the side shell 5. In this process, the conformable felt 8 in another set of cleaning and recycling component structures is arranged according to the above-mentioned steps. The old can absorb the carbon powder. When the baffle 22 moves to the top of the cleaning and recycling component, the staff holds the handle 14 and pulls the conformable felt 8. During the whole process, a small amount of carbon powder will be detached from the conformable felt 8 and float above the conformable felt 8. The baffle 22 can prevent the carbon powder from floating out and assist the personnel to replace the recycling box 6. After replacing the recycling box 6, the baffle 22 is pulled out to avoid blocking the top of the cleaning and recycling component to complete the replacement; dust suction components are provided on both sides of the side shell 5, and the dust suction components can absorb and store the cleaned and floating carbon powder. A filter 25 is also provided, and the carbon powder can be filtered through the filter 25. If outside air enters the interior from the dustproof ventilation net 19, the excess gas can also be quickly discharged through the filter 25.
