Description

Technical Field

[0001] The utility model relates to the technical field of electric power equipment, in particular to a novel generator collector ring grinding tool. Background Art

[0002] Slip rings, also known as conductive rings, slip rings, collector rings, and collector rings, can be used in any electromechanical system that requires continuous rotation while also transmitting power and signals from a fixed position to a rotating one. Slip rings can improve system performance, simplify system structure, and prevent twisting of wires during rotation.

[0003] The six units of Yunnan Huadian Ludila Hydropower Station all use SF360-60 / 15070 mixed-flow turbine generator sets produced by Tianjin Alstom Hydropower Equipment Co., Ltd. The generator uses carbon brushes and slip rings for contact connection. During the daily operation of the unit, there will be sparks between the slip rings and the carbon brushes, resulting in high temperatures of the carbon brushes and slip rings. At the same time, the sparks in the spark phenomenon will cause a short circuit between the positive and negative sides of the slip rings, causing the unit to shut down, which seriously threatens the safe operation of the unit. When the generator produces sparks during operation, it is generally because the surface of the slip ring is not smooth and there are spikes and grooves. It is necessary to use a grindstone to grind the surface of the slip ring to smooth the spikes and grooves to ensure smooth and full contact between the carbon brushes and the slip rings to eliminate the spark phenomenon.

[0004] The existing grinding tools are: one is to install the grinding stone in the brush holder, and use the pressure of the spring to press the grinding stone to the surface of the collector ring to grind the surface of the collector ring; the other is a handle-type grinding tool, which uses manpower to press the grinding stone on the surface of the collector ring to grind. The existing grinding tools have the following disadvantages: first, the spring pressure is too small, generally the spring pressure is 26N, and it cannot provide enough pressure to fully grind the surface of the collector ring; second, for the handle-type grinding tool, the collector ring grinding work needs to be carried out when the unit is running. Using manpower to press the grinding stone for grinding poses a great safety hazard. At the same time, grinding takes 20-30 minutes, which is time-consuming and labor-intensive. For this reason, we propose a new type of generator collector ring grinding tool. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] like Figure 1-Figure 5As shown in the figure, a new type of generator collector ring grinding tool includes a handle 1, the bottom of the handle 1 is fixedly connected to a connecting rod 2, the outside of the connecting rod 2 is fixedly connected to a fixing block 3, the outside of the fixing block 3 is fixedly connected to a connecting block 4, the outside of the connecting block 4 is fixedly connected to a connecting plate 5, the external thread of the connecting plate 5 is connected to an adjusting component 6, the bottom of the adjusting component 6 is fixedly connected to a connecting column 7, the connecting column 7 is a hollow structure, the bottom of the connecting column 7 is fixedly connected to an installation component 8, and the outside of the connecting column 7 is fixedly connected to a cleaning component 9.

[0025] Specifically: See Figure 1 and Figure 2 The adjusting component 6 includes a knob 601, which is made of insulating material. The bottom of the knob 601 is fixedly connected to a screw 602, and the external thread of the screw 602 is connected to a fixing plate 603. The bottom of the screw 602 is fixedly connected to a first insulating plate 604, and the fixing plate 603 is fixedly connected to the connecting plate 5. The bottom of the first insulating plate 604 is fixedly connected to a spring 606, and the other end of the spring 606 is fixedly connected to a second insulating plate 607. The first insulating plate 604 and the second insulating plate 607 are both made of epoxy resin plate, which has a good insulation effect and can well protect the safety of users. A second insulating plate 607 is provided at the bottom end of the spring 606, which can ensure sufficient pressure to press the grindstone while avoiding the insulation strength of the second insulating plate 607 being insufficient. Enough to cause accidents, so that the insulation performance of the grinding tool has double insurance, a spring 606 is installed between the first insulating plate 604 and the second insulating plate 607, which can play a buffering role. During the sliding process of the collector ring, due to the different roundness, concentricity, and pressure in four directions, it is impossible to ensure that the collector ring runs evenly at the same roundness. A buffer is required to ensure that the grinding stone is tightly attached to the surface of the collector ring to ensure the grinding effect. The bottom of the second insulating plate 607 is fixedly connected to the receiving box 605, and the outside of the receiving box 605 is fixedly connected to the connecting block 4. The receiving box 605 encapsulates the first insulating plate 606, the second insulating plate 607 and the spring 606 in the box to avoid the spring 606 from falling off during the grinding process due to poor fixation, which poses a hidden danger to the safe operation of the unit.

[0026] For further information, see Figure 4The mounting assembly 8 includes a mounting frame 801, which is made of the same insulating material. The interior of the mounting frame 801 is symmetrically threaded with studs 802, and one end of the two studs 802 is fixedly connected to a nut 803. The other ends of the two studs 802 pass through the mounting frame 801 and are fixedly connected to a splint 804. The splint 804 is against the inner wall of the mounting frame 801 to prevent it from flipping over during movement. The two splints 804 are fixedly connected to an elastic pad 805 on the side close to each other. The elastic pad 805 is made of rubber, which can prevent the splint 804 from clamping the grinding stone too tightly and prevent the grinding stone from falling. The mounting assembly 8 is used to install the grinding stone. According to the operating conditions of the slip ring, grinding stones of various specifications can be replaced through the mounting assembly 8, which are suitable for different units and grinding stones of varying coarseness and fineness, truly achieving the purpose of convenient replacement and fast grinding.

[0027] Also, see Figure 1 and Figure 2 The cleaning component 9 includes a dust box 901, and a filter 902 is fixedly connected to the inside of the dust box 901.

The suction pump 903 provides a power source for the cleaning component 9. The output end of the suction pump 903 is fixedly connected to an output pipe 904. The outside of the output pipe 904 is fixedly connected to a dust cover 905. The dust cover 905 can prevent dust from entering the interior of the suction pump 903 and keep the suction pump 903 running normally. A connecting pipe 906 is fixedly provided inside the dust box 901. One end of the connecting pipe 906 extends into the filter 9 02, the other end of the connecting tube 906 passes through the dust box 901 and is fixedly connected to a telescopic tube 907. The telescopic tube 907 is a corrugated tube and can move with the connecting column 7 to facilitate the vacuuming work of the cleaning component 9. The end of the telescopic tube 907 away from the connecting tube 906 is fixedly connected to the connecting column 7. The outside of the telescopic tube 907 is symmetrically fixedly connected with a suction nozzle 908. Both suction nozzles 908 extend to the outside of the mounting frame 801. The outside of the dust box 901 is fixedly connected with a dust exhaust pipe 909. By providing a dust collection component 9, dust can be adsorbed during the grinding process of the grindstone, which can keep the collector ring clean and tidy, and reduce the impact of dust on user health.

[0028] In summary, when using this device, first turn the knob 601, the knob 601 drives the screw 602 to rotate, and then drives the first insulating plate 604 to squeeze the spring 606, and then squeeze the second insulating plate 607, thereby forming a certain pressure, then the grinding stone is installed and placed on the surface of the slip ring, when the slip ring rotates, it drives the grinding stone to grind along with the slip ring, at the same time, start the suction pump 903, the suction pump 903 will suck the dust through the suction nozzle 908, and enter the bottom of the filter screen 902 through the telescopic tube 907 and the connecting tube 906, from The dust is left inside the dust box 901, and the dust cover 905 can prevent the dust from entering the interior of the suction pump 903. When dust accumulates inside the dust box 901, it can be discharged through the dust exhaust pipe 909. When it is necessary to replace the grinding stone of different coarseness to grind the slip ring according to demand, turn the nut 803, and the nut 803 drives the stud 802 to rotate, and then drives the splint 804 to move, so as to take out the grinding stone inside the installation frame 801, replace it with a new grinding stone and put it into the installation frame 801, and then rotate the nut 803 in the opposite direction to fix the new grinding stone.
