Description

[0002] In the electric power industry, generators are the core equipment for power production, and the stability and reliability of their operating status are directly related to the safety and efficiency of the power system. The generator rotor is a key component that rotates at high speed inside the generator, and its operating status has a decisive influence on the overall performance of the generator. However, during operation, the generator rotor is often affected by a variety of complex factors such as electromagnetic force, mechanical stress, thermal stress, etc., and is prone to imbalance, vibration, overheating and other faults, which seriously threaten the safe operation of the generator.

DETAILED DESCRIPTION

[0031] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] See also Figure 1-8 , the present invention provides a technical solution:

[0033] A generator rotor monitoring device, comprising

[0034] A monitoring frame 1, which is arranged on the outer side of the rotor body 3 and is used to monitor the running state of the rotor body 3 in real time. The monitoring frame 1 includes two monitoring plates 11, a mounting plate 112 is arranged on the inner side of the monitoring plate 11, and a monitoring sensor 16 is arranged on the surface of the mounting plate 112. The monitoring sensor 16 includes a vibration sensor for monitoring the vibration of the rotor and a temperature sensor for monitoring the temperature change of the rotor. A telescopic rod 14 is arranged on one side of the mounting plate 112, and a coupling ring 13 is arranged on one side of the telescopic rod 14. The two coupling rings 13 can be fixed to the outer side of the rotor shaft of the rotor body 3 by bolts;

[0035] The adjusting seat 2 is arranged at the bottom of the monitoring frame 1. The adjusting seat 2 is used to control the distance between the two monitoring plates 11. The adjusting seat 2 includes a mounting seat 21 and a servo motor 22. The output end of the servo motor 22 is provided with a first gear 23. Both sides of the first gear 23 are respectively provided with a rack 24 meshing with the outer side of the first gear 23. The rack 24 is connected to the monitoring plate 11 through a linkage plate 25 and a connecting rod 26.

[0036] The buffer device 4 is arranged inside the monitoring plate 11 and in contact with one side of the mounting plate 112 . The buffer device 4 is used to reduce the impact of the rotor body 3 on the mounting plate 112 during operation.

[0037] In this embodiment, please refer to Figure 7 The buffer device 4 includes a shock absorbing chamber 41, the inner cavity of the shock absorbing chamber 41 is filled with shock absorbing oil, the inner cavity of the shock absorbing chamber 41 is also provided with a damping mechanism 43, a transmission rod 44 is provided on one side of the damping mechanism 43, a sealing cover 45 is provided on one side of the shock absorbing chamber 41, one end of the transmission rod 44 is connected to a pressure cover 47, and the pressure cover 47 is in contact with one side of the mounting plate 112. In this embodiment, when the mounting plate 112 is subjected to impact force, the pressure cover 47 is pushed backward under the action of pressure, and the damping mechanism 43 is pushed backward through the transmission rod 44. Since shock absorbing oil is provided in the shock absorbing chamber 41, the oil is squeezed out through the oil filter groove of the damping mechanism 43, thereby providing damping force, reducing the impact on the pressure cover 47, and thereby reducing the impact on the mounting plate 112.

[0038] In this embodiment, please refer to Figure 2 , Figure 4 The butt joint ends of the two monitoring boards 11 are respectively provided with a butt joint groove 111 and a connecting plate 12, a positioning spring piece 121 is provided on one side of the connecting plate 12, and a clamping plate 114 is provided in the inner cavity of the butt joint groove 111, and the positioning spring piece 121 is inclined in the opposite direction of the clamping plate 114. In this embodiment, by providing the positioning spring piece 121 and the clamping plate 114, when the two monitoring boards 11 are close to each other, since the tilting direction of the positioning spring piece 121 is opposite to that of the clamping plate 114, when the connecting plate 12 enters the butt joint groove 111, The positioning spring piece 121 and the locking plate 114 do not block each other, so that the spacing between the monitoring plates 11 is successfully reduced. After the positioning spring piece 121 passes through the locking plate 114, when the monitoring plates 11 are subjected to the force of separation, the positioning spring piece 121 and the locking plate 114 will block each other, thereby preventing the monitoring plates 11 from being separated from each other. In this way, when the monitoring frame 1 rotates synchronously with the rotation of the rotor body 3, it is prevented from being affected by vibration, causing the two monitoring plates 11 to be separated from each other, thereby causing the position of the monitoring sensor 16 to move, affecting the monitoring result.

[0039] In this embodiment, please refer to Figure 2 , Figure 6, electromagnetic suction seats 15 are arranged on both sides of the monitoring plate 11, the connecting rod 26 includes a bottom column 261, the inner cavity of the bottom column 261 is provided with a reset spring 262, the top of the reset spring 262 is provided with an embedded block 263, and the top of the embedded block 263 is set to a rounded corner, and the electromagnetic suction seat 15 generates suction on the embedded block 263 after being energized. In this embodiment, the connecting rod 26 is fixed in the inner cavity of the electromagnetic suction seat 15 by energizing the electromagnetic suction seat 15. When the position setting of the monitoring sensor 16 is completed, and when the coupling ring 13 rotates the rotor body 3 After the sub-shaft connection is completed, the connection between the connecting rod 26 and the electromagnetic suction seat 15 is lost by stopping the power supply to the electromagnetic suction seat 15. At this time, the position of the connecting rod 26 is moved again by the servo motor 22. Since the top of the embedded block 263 is set as a rounded corner, the embedded block 263 moves downward and squeezes the reset spring 262, so that the connecting rod 26 is separated from the inner cavity of the electromagnetic suction seat 15. After the connecting rod 26 is disconnected from the monitoring board 11, it is moved to both sides away from the monitoring frame 1. At this time, the rotor body 3 can drive the monitoring frame 1 to rotate synchronously without interference.

[0040] In this embodiment, please refer to Figure 4 A control button 115 is fixedly connected to one side of the locking plate 114, and the control button 115 is arranged on one side of the monitoring plate 11. In this embodiment, the direction of the locking plate 114 can be adjusted by rotating the control button 115. By adjusting the direction of the locking plate 114 to be the same as the direction of the positioning spring piece 121, the two monitoring plates 11 can be unobstructed when they are separated from each other, so that the distance between the two monitoring plates 11 can be readjusted.

[0041] In this embodiment, please refer to Figure 8 The damping mechanism 43 includes a fixing ring 431, and a first oil filter plate 432 and a second oil filter plate 433 are arranged on the inner side of the fixing ring 431. The second oil filter plate 433 is fixed to the inner wall of the fixing ring 431. The first oil filter plate 432 can rotate along the inner wall of the fixing ring 431. A plurality of partitions are arranged on the inner sides of the first oil filter plate 432 and the second oil filter plate 433, and an oil filter groove is formed at the gap between the partitions. In this embodiment, by controlling the rotation of the first oil filter plate 432, the position of the partition arranged on the inner side thereof can be changed, thereby changing the overlapping area between the first oil filter plate 432 and the partition arranged on the inner side of the second oil filter plate 433. According to the change of the overlapping area, the circulation speed of the oil changes, so that the circulation speed of the oil can be adjusted according to the rotation speed of the rotor body 3, thereby changing the shock absorbing effect.

[0042] In this embodiment, please refer to Figure 3 , Figure 7 , Figure 8A second gear 42 is disposed on the outer side of the shock absorbing chamber 41, a first magnetic ring 421 is disposed on the inner wall of the second gear 42, a second magnetic ring 434 is disposed on the outer side of the first oil filter plate 432, the first magnetic ring 421 and the second magnetic ring 434 attract each other, a linkage bar 113 is further disposed inside the monitoring plate 11, one side of the linkage bar 113 is connected to the connecting plate 12, and one side of the linkage bar 113 is meshed with the outer side of the second gear 42. In this embodiment, the larger the size of the monitored rotor body 3 is, the larger the spacing between the two monitoring plates 11 is, and the smaller the size of the rotor body 3 is, the smaller the spacing between the two monitoring plates 11 is, thereby changing the connecting plate 12. 2 is located at a depth in the inner cavity of the docking groove 111, so that when the spacing of the monitoring plates 11 is adjusted, the connecting plate 12 drives the linkage bar 113 to move, and the movement of the linkage bar 113 drives the second gear 42 to rotate, and the first magnetic ring 421 and the second magnetic ring 434 attract each other, thereby driving the first oil filter plate 432 to rotate. Therefore, when the monitoring frame 1 monitors a larger rotor body 3, the oil filter groove becomes smaller, so that the shock absorption capacity of the buffer device 4 is enhanced. When monitoring a smaller rotor body 3, the oil filter groove becomes larger, so that the shock absorption capacity of the buffer device 4 becomes smaller, and it is quickly adjusted to the most suitable shock absorption state to ensure that the sensor can accurately capture the rotor parameters.

[0043] In this embodiment, please refer to Figure 7 A number of pressure relief springs 46 are arranged on the outside of the pressure cover 47, and one end of the pressure relief spring 46 is fixed to the surface of the sealing cover 45. In this embodiment, the pressure relief spring 46 is provided to provide a buffering force for the pressure cover 47, thereby further increasing the shock absorbing capacity of the buffer device 4. At the same time, after the impact force disappears, the pressure relief spring 46 rebounds and pushes the pressure cover 47 back to its original position, thereby avoiding affecting the position of the monitoring sensor 16.

[0044] Working principle of the present invention:

[0045] Step 1. Since the length of the telescopic rod 14 can be extended and retracted, the spacing between the two monitoring plates 11 is adjusted by the adjusting seat 2, and the length of the telescopic rod 14 is controlled, and the telescopic rod 14 drives the two coupling rings 13 to reduce the spacing, so that the two coupling rings 13 clamp the rotor shaft, and the coupling ring 13 is fixed to the outside of the rotor shaft by bolts. At the same time, since the two monitoring plates 11 are gradually controlled by the adjusting seat 2 to approach the claw poles and the outside of the magnetic field winding of the rotor body 5, when the monitoring sensor 16 contacts the claw poles and the magnetic field winding, the rotor body 3 rotates synchronously with the rotation of the rotor shaft under the drive of the telescopic rod 14 during the rotation process. At this time, the vibration of the rotor during the rotation process is monitored by the vibration sensor, and it is judged whether the rotor has problems such as imbalance and bearing wear through the vibration data. The temperature change of the magnetic field winding during operation is monitored by the temperature sensor, and the vibration and temperature change of the rotor body 3 during operation are monitored, so as to accurately monitor the operating state of the generator rotor;

[0046] Step 2, by placing the rotor body 3 between the two monitoring plates 11, and driving the first gear 23 to rotate through the servo motor 22, since the outer edge of the first gear 23 is meshed with the inner side of the rack 24, when the first gear 23 rotates, it drives the two racks 24 to move, and according to the rotation direction of the first gear 23, the two racks 24 can be made to move toward each other, and the rack 24 drives the linkage plate 25 to move, so that the spacing between the two linkage plates 25 gradually decreases, and when the spacing between the two linkage plates 25 gradually decreases, the spacing between the two monitoring plates 11 gradually decreases through the connecting rod 26, and the spacing of the monitoring plates 11 becomes smaller, so that the monitoring sensor 16 contacts the claw poles and the outer sides of the magnetic field winding of the rotor body 5. According to the above principle, by controlling the rotation of the first gear 23 in the opposite direction by 222, the two monitoring plates 11 can be separated toward each other, and the spacing between the monitoring plates 11 can be increased, so as to adapt to the rotor body 3 with a larger size;

[0047] Step 3: Since the rotor body 3 will generate high-speed rotation during operation, and the monitoring plate 11 is connected to the rotor shaft through the telescopic rod 14, the rotor body 3 generates an impact force on the mounting plate 112 when it rotates at a high speed. By providing a buffer device 4 on one side of the mounting plate 112, when the mounting plate 112 moves backward after being impacted, the mounting plate 112 moves backward to push the pressure cover 47 to move backward, and the pressure cover 47 moves backward to push the transmission rod 44 to move backward, and squeezes the decompression spring 46 to cause it to deform, and the transmission rod 44 moves backward to push the damping mechanism 43 to move backward. Since the inner cavity of the shock absorbing chamber 41 is filled with shock absorbing oil, when the damping mechanism 43 moves backward, the oil passes through the damping mechanism 43. The oil filter groove in the filter is squeezed out, and at this time, a damping force is generated under the action of the shock-absorbing oil. When the damping mechanism 43 moves backward, the moving speed slows down, thereby alleviating part of the impact force on the pressure cover 47. When the impact force disappears, the decompression spring 46 rebounds, causing the pressure cover 47 to move forward, and the damping mechanism 43 moves forward through the forward movement of the pressure cover 47. Due to the existence of the damping force, the forward movement speed of the damping mechanism 43 slows down, thereby reducing the reaction force on the pressure cover 47, thereby alleviating the vibration of the mounting plate 112, and the monitoring sensor 16 is installed on the mounting plate 112, so that the monitoring sensor 16 is less affected by vibration, thereby ensuring the accuracy of the monitoring device during monitoring.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. The present invention is not limited to the above embodiments.
