Description

Technical Field

[0001] The present invention relates to the technical field of carbon brush dust removal, and in particular to an automatic carbon brush dust removal device for a generator set. Background Art

[0002] As critical infrastructure for water resource regulation, flood control and drainage, and irrigation and water supply, the stable operation of hydraulic pumping stations is directly linked to the balance between social production and life and the ecological environment. Generator sets, the core power equipment of hydraulic pumping stations, are responsible for converting mechanical energy into electrical energy, providing power support for various equipment in the pumping station. Their operational reliability and efficiency have a decisive impact on the overall function of the pumping station.

[0003] In hydraulic pump station generator sets, carbon brushes are key components for conducting electrical energy between rotating and stationary parts and are widely used in the generator's slip rings or commutator systems. The continuous sliding contact between the carbon brushes and the slip rings or commutator inevitably produces carbon dust due to mechanical friction. This carbon dust, primarily composed of fine particles formed by brush wear, has a small particle size and strong adsorption properties, making it prone to accumulation on the surfaces of the carbon brushes, slip rings / commutator, and surrounding electrical components. If not promptly cleaned, this accumulation can lead to poor electrical contact, localized overheating, and even short-circuit failures, seriously impacting the generator set's operational stability and lifespan.

[0004] The patent document of "A carbon brush dust collector device for a bulb cross-flow unit generator" disclosed in Chinese patent CN217724990U includes a device support frame, a dust removal box, an air inlet duct, an air outlet duct and a centrifugal fan. A dust removal box is installed on the top of the device support frame, and an air inlet duct is connected to the dust removal box.

[0005] The above-mentioned device uses a centrifugal fan to form a negative pressure in the dust removal box, sucks the carbon powder into the water tank, and uses the mixture of water and carbon powder to achieve separation. However, the device has the following defects: First, the water in the water tank will be saturated with carbon powder after long-term use, affecting the treatment effect, and the water needs to be changed regularly. When changing the water, the carbon powder treatment must be stopped, which seriously reduces the work efficiency; second, the water and carbon powder are stirred only by the waves generated by the negative pressure of the fan, and the stirring effect is poor, resulting in insufficient mixing of carbon powder and water, affecting the separation efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0021] The following will describe various embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] like Figure 1-7 As shown, an automatic carbon brush dust removal device for a generator set includes a box body 1, which serves as the main supporting structure of the device. A closed space is formed inside the box body to realize carbon powder processing. An air intake pipe 2 is connected to one side of the top of the box body 1. One end of the air intake pipe 2 corresponds to the carbon brush on the generator set and is used to introduce the carbon powder generated by the carbon brush into the box body 1. A fan 5 is installed on the other side of the box body 1. The fan 5 provides negative pressure power for the device. Its suction end is plugged into the interior of the box body 1 to extract air in the box body 1 to form negative pressure.

[0023] The interior of the box body 1 is connected to a rectangular frame 38, which divides the interior of the box body 1 into two independent spaces, the upper part of the rectangular frame 38 being the first water storage chamber and the lower part being the second water storage chamber. The two water storage chambers can be used alternately for mixing carbon powder and water. Two inspection doors (not shown in the figure) are hinged on the back of the box body 1. The two inspection doors correspond to the two water storage chambers respectively and are used to clean the interiors of the two water storage chambers.

[0024] The left side of the box body 1 is connected to the first water inlet pipe 34, the first drain pipe 35, the second water inlet pipe 36 and the second drain pipe 37 from top to bottom. Among them, the first water inlet pipe 34 and the first drain pipe 35 correspond to the first water storage chamber and are respectively used to fill water into and drain water from the first water storage chamber. The second water inlet pipe 36 and the second drain pipe 37 correspond to the second water storage chamber and are respectively used to fill water into and drain water from the second water storage chamber. A second solenoid valve is installed on the second drain pipe 37 and the first drain pipe 35. By controlling the opening and closing of the second solenoid valve, the automatic drainage of the water storage chamber can be achieved, and the water change operation can be completed in conjunction with the water inlet pipe. The interior of the box body 1 is slidably connected to a lifting plate 3, which can slide up and down along the inner wall of the box body 1. Two air guide tubes 7 are connected inside the box body 1. The air guide tubes 7 are used to conduct the airflow containing carbon powder. The top ends of the two air guide tubes 7 are connected to telescopic tubes 6. The telescopic tubes 6 are telescopic and can adapt to the up and down movement of the lifting plate 3. The other ends are respectively connected to one end of the air inlet pipe 2 and the suction end of the fan 5, thereby forming an air flow channel of "air inlet pipe 2-telescopic tube 6-air guide tube 7-first water storage chamber-fan 5".

[0025] The interior of the rectangular frame 38 is connected with a first docking tube 8 and a second docking tube 9. Both the first docking tube 8 and the second docking tube 9 are connected to the second water storage chamber, and the first docking tube 8 and the second docking tube 9 correspond to the two air ducts 7 respectively. When the two air ducts 7 are docked with the first docking tube 8 and the second docking tube 9 respectively, the air flow can be conducted to the second water storage chamber. A docking mechanism and a stirring mechanism are provided on the box body 1. The docking mechanism is used to achieve precise docking of the air duct 7 with the first docking tube 8 and the second docking tube 9, and the stirring mechanism is used to enhance the mixing effect of water and carbon powder in the water storage chamber.

[0026] The upper surface of the rectangular frame 38 is connected to a water baffle 4. The water in the first water storage chamber is located between the water baffle 4 and the left side wall of the box body 1. The water baffle 4 is used to prevent the water in the first water storage chamber from overflowing into the air duct 7 connected to the fan 5, affecting the powder removal work. The inside of the water baffle 4 is provided with a through groove for the lifting plate 3 to slide up and down. The inside of the water baffle 4 is slidingly connected to two slides 26. The sides of the two slides 26 that are close to each other are respectively connected to the upper surface and bottom surface of the lifting plate 3. When the lifting plate 3 moves up and down, the slide 26 slides synchronously with it, always maintaining the seal between the water baffle 4 and the lifting plate 3, further avoiding water leakage.

[0027] The docking mechanism includes two second movable plates 14 slidably connected to the inside of the rectangular frame 38, and the second movable plates 14 can slide in the horizontal direction of the rectangular frame 38. The two second movable plates 14 are connected to a second spring 15 on the side away from each other, and the other end of the second spring 15 is connected to the inner wall of the box body 1. The upper surface of the two second movable plates 14 is connected to a wedge plate 16. A circular hole for the air guide tube 7 to pass through is opened inside the rectangular frame 38, and the circular hole provides a channel for the movement of the air guide tube 7. The two wedge plates 16 are connected to a baffle plate 17 for blocking the circular hole on the side away from each other. The baffle plate 17 can move synchronously with the second movable plate 14, and in the initial state, the circular hole is blocked to prevent water leakage. The interior of the two baffle plates 17 is provided with a long strip hole 18 adapted to the air guide tube 7. When the long strip hole 18 is aligned with the circular hole, the air guide tube 7 can pass through the circular hole and the long strip hole 18 to dock with the first docking tube 8 and the second docking tube 9.

[0028] The docking mechanism also includes a connecting column 10 that is slidably connected to the inside of the box body 1. The connecting column 10 extends in the vertical direction. The lifting plate 3 is connected to the outer surface of the connecting column 10. The movement of the connecting column 10 can drive the lifting plate 3 to slide up and down synchronously. The bottom end of the connecting column 10 is slidably inserted into the inside of the rectangular frame 38. The bottom end is connected to a trapezoidal plate 11 that is adapted to the wedge plate 16. The two inclined surfaces of the trapezoidal plate 11 are respectively fitted with the inclined surfaces of the two wedge plates 16. When the trapezoidal plate 11 moves downward, the inclined surface can squeeze the wedge plate 16, pushing the two second movable plates 14 away from each other.

[0029] The outer surface of the trapezoidal plate 11 is connected to the first movable plate 12, and the bottom surface of the first movable plate 12 is connected to the first spring 13. The other end of the first spring 13 is connected to the inner bottom wall of the rectangular frame 38. The first spring 13 provides an upward reset force for the trapezoidal plate 11. When the external force is removed, the trapezoidal plate 11 and the connecting column 10 can be driven to reset upward.

[0030] The top of the connecting column 10 is connected to the box body 19, and the internal sliding connection of the box body 19 is connected to the limit plate 20. The limit plate 20 can slide horizontally along the box body 19. One side of the limit plate 20 is connected to the third spring 21 and the pull rod 22. The other end of the third spring 21 is connected to the inner wall of the box body 19. When the third spring 21 is in a natural state, it can push the limit plate 20 out of the box body 19. The other end of the pull rod 22 slides through the box body 19 and is connected to a pull head. Pulling the pull head can drive the limit plate 20 to compress the third spring 21 and retract the box body 19.

[0031] A support plate 23 is connected to the upper surface of the box body 1, and the support plate 23 provides guidance and limitation for the limit plate 20. A slide groove 24 is provided inside the support plate 23 for the limit plate 20 to slide up and down. The slide groove 24 extends in the vertical direction, and the limit plate 20 can move up and down in the slide groove 24. A limit groove 25 adapted to the limit plate 20 is provided inside the support plate 23, and the limit groove 25 is connected to the bottom of the slide groove 24. When the limit plate 20 moves to the bottom of the slide groove 24, the third spring 21 can push the limit plate 20 to fit into the limit groove 25, thereby connecting the position of the column 10 to ensure stable docking of the air guide tube 7 and the docking tube.

[0032] The stirring mechanism includes a first shell 27 and a second shell 28, both of which are connected to the right side of the box body 1 and serve as the installation cavity of the fan blade 31. A rotating shaft 29 is rotatably installed between the first shell 27 and the box body 1 and between the second shell 28 and the box body 1. The rotating shaft 29 horizontally passes through the shell and the box body 1, and its outer surface is connected with fan blades 31 and a group of stirring blades 30, one group of stirring blades 30 is located in the first water storage chamber, for stirring the water and carbon powder in the first water storage chamber, and the other group of stirring blades 30 is located in the second water storage chamber, for stirring the water and carbon powder in the second water storage chamber. Correspondingly, one fan blade 31 is located in the first shell 27, and the other fan blade 31 is located in the second shell 28. The rotation of the fan blade 31 can drive the rotating shaft 29 and the stirring blade 30 to rotate synchronously.

[0033] The exhaust end of the fan 5 is connected to a first exhaust pipe 32, and the other end of the first exhaust pipe 32 is inserted into the interior of the first shell 27 for introducing the airflow discharged by the fan 5 into the first shell 27 to drive the fan blades 31 therein. The outer surface of the first exhaust pipe 32 is connected to a second exhaust pipe 33, and the other end of the second exhaust pipe 33 is inserted into the interior of the second shell 28 for introducing the airflow into the second shell 28. A first one-way valve is installed on both the second exhaust pipe 33 and the first exhaust pipe 32. By controlling the opening and closing of the first one-way valve, the selective delivery of the airflow to the first shell 27 or the second shell 28 can be achieved, thereby controlling the rotation of the stirring blade 30 in the corresponding water storage chamber.

[0034] The working process of the present invention is: In the initial state, the air guide pipe 7 extends into the first water storage chamber, one end of the air intake pipe 2 corresponds to the carbon brush of the generator set, the first water storage chamber and the second water storage chamber are filled with an appropriate amount of water, the first one-way valve on the first exhaust pipe 32 is open, and the first one-way valve on the second exhaust pipe 33 is closed.

[0035] After starting the fan 5, the fan 5 draws air from the first water storage chamber through the telescopic tube 6 and the air duct 7, so that a negative pressure is formed in the first water storage chamber. Under the action of the negative pressure, the carbon powder generated by the carbon brush of the generator set is sucked into the first water storage chamber through the air intake pipe 2, the telescopic tube 6 and the air duct 7. The carbon powder enters the water with the air flow and mixes with the water to achieve preliminary separation.

[0036] At the same time, the airflow discharged by the fan 5 enters the first shell 27 through the first exhaust pipe 32, driving the fan blades 31 in the first shell 27 to rotate. The fan blades 31 drive the stirring blades 30 in the first water storage chamber to rotate through the rotating shaft 29, thereby enhancing the stirring and mixing effect of water and carbon powder and improving the separation efficiency. The treated clean air is discharged through the fan 5.

[0037] When the water in the first water storage chamber needs to be replaced due to saturation of carbon powder, the box body 19 is pressed downward, and the box body 19 drives the connecting column 10, the lifting plate 3 and the trapezoidal plate 11 to move downward. The first spring 13 is compressed. During the downward movement of the trapezoidal plate 11, its inclined surface squeezes the wedge plate 16, pushing the two second movable plates 14 away from each other and compressing the second spring 15. The hole-blocking plate 17 moves synchronously with the second movable plate 14 to align the elongated hole 18 with the circular hole on the rectangular frame 38.

[0038] When the air guide tube 7 passes through the circular hole and the long hole 18 and docks with the first docking tube 8 and the second docking tube 9, the third spring 21 will push the limit plate 20 to fit into the limit groove 25, fixing the position of the connecting column 10. At this time, the first one-way valve on the first exhaust pipe 32 is closed, and the second one-way valve on the second exhaust pipe 33 is opened. The airflow discharged by the fan 5 enters the second shell 28, driving the stirring blade 30 in the second water storage chamber to rotate, and the device switches to the second water storage chamber for carbon powder processing.

[0039] At the same time, open the second solenoid valve on the first drain pipe 35 to drain the sewage in the first water storage chamber, and then inject new water through the first water inlet pipe 34 to complete the water change of the first water storage chamber. After the water change is completed, pull the pull rod 22 to disengage the limit plate 20 from the limit groove 25, so that the device can be reset and switched back to the first water storage chamber to achieve continuous dust removal without stopping.
