Description

Technical Field

[0001] The present application relates to the field of electrical maintenance technology, and in particular to a generator end maintenance auxiliary device and maintenance system. Background Art

[0002] During the overhaul of the generator, the rotor needs to be regularly pulled out for inspection. The existing inspection method is mainly to first pull the rotor out of the stator, and then have personnel enter the stator chamber to perform a series of inspections and tests.

[0003] However, the above maintenance method requires the removal of a large number of parts and takes a long time. Generally speaking, compared with not pulling out the rotor, pulling out the rotor for maintenance requires additional manpower time. In addition, the rotor is 15.38 meters long and 2 meters in diameter, while the minimum air gap with the stator is only 58 mm. It is easy to cause collisions and other problems during the extraction process, which can damage the equipment.

[0004] The inner wall of the stator at both ends along its axial direction has irregular protruding sections, so that the inner wall at the stator opening forms a stepped structure. The robot device can only inspect the relatively flat inner wall inside the stator, and cannot inspect the front and rear sides of the protruding section. If the sensor is inserted into the stator through a long rod or other tool, the long rod cannot fit the inner wall of the stator inside the protruding section due to the obstruction of the protruding section, so that the inspection sensor cannot fit to the inner wall of the stator, and the inner wall of the stator cannot be fully inspected by the sensor. Utility Model Content

[0005] Based on this, it is necessary to provide a generator end maintenance auxiliary device and maintenance system to address the problem that when the sensor is inserted into the stator through tools such as a long rod, the long rod cannot fit the inner wall of the stator within the step section due to the obstruction of the step section, and thus the maintenance sensor cannot fit to the inner wall of the stator, and the inner wall of the stator cannot be fully inspected by the sensor.

[0053] See also Figure 2 , Figure 2 A schematic structural diagram of a generator end maintenance auxiliary device 100 in an embodiment of the present application is shown. The generator end maintenance auxiliary device 100 provided in an embodiment of the present application includes: a rod body 110 and a support assembly 120.

[0054] In the generator end maintenance auxiliary device 100, a first through hole 121 is provided at one end of the support assembly 120, one end of the rod body 110 is passed through the first through hole 121 and is detachably fixedly connected to the support assembly 120, the first through hole 121 extends along a first direction OX, one end of the support assembly 120 away from the rod body 110 is connected to the sensor, and the thickness of the support assembly 120 gradually expands along the second direction OY in the direction away from the rod body 110 along the first direction OX.

After the rod body 110 is adjusted to a suitable position, the end of the rod body 110 away from the support assembly 120 is held to extend the entire generator end maintenance auxiliary device 100 from the opening 212 of the stator hole into the gap between the stator 210 and the rotor 211, and then the support assembly 120 is inserted into the first through hole 121. After the attached sensor passes through the step protruding from the opening 212 of the stator 210 toward the rotor 211, the rod body 110 is held to move the entire generator end maintenance auxiliary device 100 toward the inner wall of the stator 210. Since the thickness of the support assembly 120 along the second direction OY gradually expands along the first direction OX toward the direction away from the rod body 110, even if the side wall of the rod body 110 has abutted against the step at the opening 212 of the stator 210, the end of the support assembly 120 away from the rod body 110 can also fit against the inner wall of the stator 210, so that the sensor arranged on the end of the support assembly 120 away from the rod body 110 can fit against the inner wall of the stator 210, and the inner wall of the stator 210 can be fully inspected by the sensor.

If it is necessary to adjust the position of the rod body 110 and the support member 130, it is only necessary to remove the first fastener 140, then remove the pressing block 122, and then adjust the position of the rod body 110 relative to the support member 130, and then cover the pressing block 122 on the first through groove 131, and then penetrate the first fastener 140 into the second through hole 124 and the first connecting hole 132, so as to connect the pressing block 122 with the support member 130, so that the generator end maintenance auxiliary device 100 can be suitable for generators under different working conditions.

[0059] See also Figure 2 , Figure 3 as well as Figure 4In one embodiment, the support member 130 includes a connecting rod 134 and a plurality of support portions 133, one end of the rod body 110 is connected to the side wall of the connecting rod 134, and the plurality of support portions 133 are respectively connected to the side of the connecting rod 134 away from the rod body 110, and the thickness of the support portion 133 along the second direction OY gradually expands along the first direction OX away from the rod body 110, and the end of the support portion 133 away from the rod body 110 is connected to the sensor, so that by setting a plurality of support members 130, the support assembly 120 can be installed with more sensors, so that a wider range of the inner wall of the stator 210 can be inspected, thereby improving efficiency.

[0060] Specifically, there are two support members 130 , and the two support members 130 are respectively connected to two ends of the connecting rod 134 along the axial direction, so as to adapt to the arc-shaped inner wall of the stator 210 .

[0061] See also Figure 2 , Figure 3 as well as Figure 5 In one embodiment, one side of the two sides of the support portion 133 arranged at intervals along the second direction OY is parallel to the first direction OX, and the other side has an inclined surface 135, the inclined surface 135 is angled with the first direction OX and is arranged at an angle with the second direction OY. Specifically, one side of the two side surfaces of the support portion 133 arranged at intervals along the second direction OY is parallel to the first direction OX and is perpendicular to the second direction OY, the inclined surface 135 is parallel to the third direction, the inclined surface 135 is angled with the first direction OX and is arranged at an angle with the second direction OY, so that the thickness of the support portion 133 along the second direction OY is along the first direction It gradually expands in the direction OX away from the rod body 110. In this embodiment, when the generator end maintenance auxiliary device 100 is used, the inclined surface 135 of the support portion 133 is directed toward the inner wall of the stator 210, and the other side surface is directed toward the rotor 211. Therefore, when the generator end maintenance auxiliary device 100 is moved, the side surface of the support portion 133 away from the inclined surface 135 along the second direction OY is always parallel to the first direction OX, that is, parallel to the axial direction of the rotor 211, thereby preventing the generator end maintenance auxiliary device 100 from hitting the rotor 211 during movement, thereby protecting the rotor 211 during the maintenance process.

[0062] See also Figure 2 , Figure 3 as well as Figure 5 In one embodiment, the generator end maintenance auxiliary device 100 also includes a container member 150; the end of the support assembly 120 away from the rod body 110 is connected to the container member 150, and the container member 150 is provided with a receiving hole 151, and the receiving hole 151 is used to receive the sensor and allow the sensor to partially extend out of the receiving hole 151, so that the sensor can be installed through the receiving hole 151 of the container member 150, thereby protecting the main structure of the sensor.

Thus, the sensor can be fixed in the receiving hole 151 by inserting rivets, screws and other components through the fixing through hole 152, and the receiving hole 151 is provided along the third direction OZ, so that after the support assembly 120 enters the stator hole, the sensor can face the stator 210.

The second connection hole 125 is opened on one end surface of the support assembly 120 away from the rod body 110. The center line of the openings 212 of the two second connection holes 125 is at an angle to the second direction OY, so that the side of the container component 150 close to the inner wall of the stator 210 is at an angle to the second direction OY and the third direction OZ, so that the opening direction of the accommodating hole 151 is set at an angle to both the second direction OY and the third direction OZ, so that the direction of the container component 150 close to the inner wall of the stator 210 adapts to the curvature of the inner wall of the stator 210, so that the sensor protruding from the accommodating hole 151 can better fit the inner wall of the stator 210.

The two third through holes 153 are symmetrically distributed on both sides of the accommodating hole 151 along the first direction OX, so that the third through holes 153 avoid the accommodating hole 151 and the fixing through hole 152, thereby preventing the installation of the sensor in the accommodating hole 151 from being interfered with by the second fastener 141.

[0068] See also Figure 5 and Figure 7In one embodiment, the opening of the accommodating hole 151 protrudes from the supporting assembly 120 along the second direction OY, so that the sensor protruding from the opening of the accommodating hole 151 can protrude from the supporting assembly 120 along the second direction OY, thereby ensuring that the sensor can fit the inner wall of the stator 210.

[0070] An embodiment of the present application further provides a maintenance system, the maintenance system comprising: a sensor (not shown), a signal transmission module (not shown), a display module (not shown), and a generator end maintenance auxiliary device 100;

[0071] The sensor, the signal transmission module and the display module are connected in sequence, and the signal transmission module is used to transmit the signal data monitored by the sensor to the display module.

[0072] In actual use of the above-mentioned maintenance system, the sensor is first connected to the end of the support assembly 120 away from the rod body 110, and is set in a direction perpendicular to the first direction OX. Then, the rod body 110 is inserted into the first through hole 121, and the rod body 110 is adjusted in the first through hole 121 along the first direction OX to adjust the distance between the end of the rod body 110 away from the support assembly 120 and the support assembly 120. After the rod body 110 is adjusted to a suitable position, the end of the rod body 110 away from the support assembly 120 is held to extend the entire generator end maintenance auxiliary device 100 from the opening 212 of the stator hole into the gap between the stator 210 and the rotor 211, and then the support assembly 120 with the sensor is passed through the opening 212 of the stator 210 toward the rotor 211. After the protruding step 1 is removed, the rod body 110 is held to bring the entire generator end maintenance auxiliary device 100 closer to the inner wall of the stator 210. Since the thickness of the support assembly 120 along the second direction OY gradually expands along the first direction OX in the direction away from the rod body 110, even if the side wall of the rod body 110 has abutted against the step 212 of the opening of the stator 210, the end of the support assembly 120 away from the rod body 110 can also fit with the inner wall of the stator 210, so that the sensor provided on the end of the support assembly 120 away from the rod body 110 can fit with the inner wall of the stator 210, and then the inner wall of the stator 210 can be fully inspected by the sensor, and the monitored signal data can be transmitted to the display module through the signal transmission module for analysis and judgment by the operator.
