Description

Technical Field

[0001] This invention relates to the field of hydroelectric generator technology, specifically to an intelligent replacement device for the stator winding of a hydroelectric power station generator. Background Technology

[0002] The stator of a hydroelectric generator is the stationary component of the generator. It consists of a frame, iron core, windings, copper rings, and foundation screws. The frame is the structural component that fixes the iron core. The iron core and windings are essential electromagnetic parts of the stator for generating a rotating magnetic field and ensuring the flow of magnetic flux and current. The windings are composed of many wire bars arranged in a specific pattern. The wire bars are usually embedded in slots in the iron core in two layers and connected to form a circuit using a specific wiring method. After the current is collected through the copper ring leads, the electrical power is output. The stator windings of a hydroelectric generator are an important component of the generator stator, mainly made of copper wire and installed on the stator iron core.

[0003] The existing technology has the following problems: manual operation is extremely slow. Stator winding replacement involves many complicated steps such as disassembly, cleaning, installation, and debugging. During disassembly, workers have to use a variety of tools to carefully disconnect the winding from the stator. Because the winding is tightly wound and the spacing requirements are strict, the slightest carelessness may damage the stator core and other components. They can only proceed with caution and step by step, which greatly slows down the progress. When installing a new winding, it is necessary to place it accurately and ensure that the winding is compliant. This requires constant adjustment and calibration, and repeated checks and corrections. The whole process is lengthy and inefficient. Summary of the Invention

This device solves the problem of extremely slow manual operation. Stator winding replacement involves many complex steps, including disassembly, cleaning, installation, and debugging.

[0030] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0031] Reference Figures 1-7As shown, an intelligent replacement device for the stator winding of a hydropower station generator includes a top plate 1. Several telescopic components 2 are fixedly installed on the bottom surface of the top plate 1, symmetrically distributed about the center line of the top plate 1. Several moving grooves 3 are formed on the upper surface of the top plate 1, linearly distributed along the edge of the top plate 1. A first lead screw 4 is rotatably installed on the inner wall of each of the moving grooves 3. A moving plate 5 is provided below the top plate 1, threadedly connected to each of the first lead screws 4. A sliding groove 6 is formed on the bottom surface of the moving plate 5, with a second lead screw 7 and a third lead screw 8 rotatably installed on the inner wall of the sliding groove 6. A feeding component 9 is sleeved on the outer surface of the second lead screw 7, and the feeding component 9 is slidably connected to the third lead screw 8. A replacement component 10 is sleeved on the outer surface of the third lead screw 8, and the replacement component 10 is slidably connected to the second lead screw 7. Both the second lead screw 7 and the third lead screw 8 are externally powered. The bottom surface of the top plate 1 corresponding to the replacement component 10 is fixedly installed with a first hydraulic rod 11. The lower end of the first hydraulic rod 11 is fixedly installed with a storage rod 12. Before replacing the stator winding, the operator places the same number of stator windings in the storage rod 12. When replacing the stator winding, the second lead screw 7 rotates to move the feeding component 9 to the side away from the replacement component 10. The first lead screw 4 and the third lead screw 8 cooperate to make the replacement component 10 remove the stator winding from the stator. The operator collects the removed copper wire. Then, the third lead screw 8 rotates to move the replacement component to the side away from the feeding component 9. The first lead screw 4 and the third lead screw 8 cooperate to make the feeding component 9 remove the material from the storage rod 12 and install the stator winding into the corresponding position in the stator.

[0032] like Figure 3 As shown, the telescopic assembly 2 includes a first sleeve 201, with a fourth lead screw 202 rotatably mounted on the inner wall of the first sleeve 201. A second sleeve 203 is disposed inside the first sleeve 201, and a connecting plate 204 corresponding to the fourth lead screw 202 is fixedly mounted inside the second sleeve 203. The connecting plate 204 is threadedly connected to the fourth lead screw 202. A threaded tube 205 is disposed inside the second sleeve 203, slidably connected to the fourth lead screw 202, rotatably connected to the connecting plate 204, and threadedly connected to the fourth lead screw 202. The second sleeve 203 has a third sleeve 206 inside. The threaded tube 205 is threadedly connected to the third sleeve 206. When the telescopic component 2 is deployed, the fourth lead screw 202 rotates and pushes the second sleeve 203 through the connecting plate 204. The connecting plate 204 drives the threaded tube 205 to move, while the fourth lead screw 202 drives the threaded tube 205 to rotate. The rotation of the threaded tube 205 causes the third sleeve 206 to move along the axial direction of the threaded tube 205. When the top plate 1 moves to the appropriate position, the fourth lead screw 202 stops rotating. The self-locking mechanism of the threaded tube achieves the limiting of the telescopic component 2.

[0033] like Figure 4 As shown, the feeding assembly 9 includes a first slider 901, which is threadedly connected to a second lead screw 7 and slidably connected to a third lead screw 8. A first telescopic spindle 902 is rotatably mounted on the bottom surface of the first slider 901. A fixing plate 903 is fixedly mounted on the lower end of the first telescopic spindle 902. Storage slots 904 are provided on both the left and right sides of the fixing plate 903. Two second hydraulic rods 905 are fixedly mounted on the inner wall of the storage slots 904. The two second hydraulic rods 905 are symmetrically distributed about the center line of the storage slots 904. Push plates 906 are provided on both sides of the fixed plate 903. The push plates 906 are fixedly connected to two second hydraulic rods 905 on the same side. An embedding groove 907 is fixedly installed on the side of the fixed plate 903 near the storage rod 12. A rotating plate 908 is rotatably installed on the inner wall of the embedding groove 907. A third hydraulic rod 909 is fixedly installed on the upper surface of the rotating plate 908. A picking plate 910 is fixedly installed on the upper end of the third hydraulic rod 909. When the feeding assembly 9 removes the stator winding from the storage rod 12, the feeding assembly 9 moves to the corresponding position and rotates. The rotating plate 908 rotates via gears. When the picking plate 910 aligns with the stator winding to be removed, the rotating plate 908 stops rotating, the third hydraulic rod 909 unfolds, allowing the stator winding to enter the picking plate 910. Simultaneously, the first hydraulic rod 11 unfolds, and the first telescopic main shaft 902 retracts, causing the picking plate 910 to remove the stator winding. Subsequently, the rotating plate 908 returns to its original position. After the feeding assembly 9 moves to a suitable position, the first telescopic main shaft 902 unfolds, causing the fixing plate 903 to drive the stator winding into the corresponding groove. The push plate 906 is aligned with the groove, and the second hydraulic rod 905 pushes the stator winding into the corresponding groove through the push plate 906. After the stator winding enters the first groove, it disengages from the take-up plate 910. When placing the stator winding into the second groove, the stator winding is first placed in the take-up plate 910. Then, the first telescopic main shaft 902 moves and rotates, so that the push plate 906 on the other side aligns with another groove. The second hydraulic rod 905 pushes the stator winding into another groove through the other push plate 906.

[0034] like Figure 5As shown, the replacement component 10 includes a second slider 1001, which is threadedly connected to a third lead screw 8 and slidably connected to a second lead screw 7. A second telescopic spindle 1002 is fixedly mounted on the lower end of the second slider 1001, and an extension plate 1003 is fixedly mounted on the lower end of the second telescopic spindle 1002. A first electric actuator 1004 and a second electric actuator 1005 are fixedly mounted inside the extension plate 1003. The first electric actuator 1004 and the second electric actuator 1005 are symmetrically distributed about the center line of the extension plate 1003. A shearing blade 1006 is fixedly mounted on the lower end of the first electric actuator 1004, and a material handling clamp 1 is fixedly mounted on the lower end of the second electric actuator 1005. 007, the third lead screw 8 and the first lead screw 4 cooperate to move the entire replacement assembly 10 above the copper wire on the stator. The second telescopic spindle 1002 unfolds and rotates so that the shearing cutter 1006 corresponds to the copper wire. The first electric push rod 1004 unfolds so that the shearing cutter 1006 cuts the copper wire. The third lead screw 8, the first lead screw 4 and the second telescopic spindle 1002 cooperate to make the shearing cutter 1006 cut multiple sets of copper wire in sequence. Then the second electric push rod 1005 unfolds so that the material pick-up clamp 1007 corresponds to the copper wire. The third lead screw 8 and the first lead screw 4 cooperate to make the material pick-up clamp 1007 remove the copper wire from the stator. Then it returns to its original position, and the staff collects the copper wire.

[0035] like Figure 6 As shown, a first rotating shaft 13, a second rotating shaft 14, and a third rotating shaft 15 are rotatably mounted on the side of the top plate 1 corresponding to the first lead screw 4. The first rotating shaft 13, the second rotating shaft 14, and the third rotating shaft 15 are respectively fixedly connected to several first lead screws 4. A first roller 16 is fixedly mounted on the end of the first rotating shaft 13 away from the first lead screw 4. A second roller 17 is fixedly mounted on the end of the second rotating shaft 14 away from the first lead screw 4. A third roller 18 corresponding to the second roller 17 is fixedly mounted on the end of the third rotating shaft 15 away from the first lead screw 4. The third roller 18 and the second roller 17 are connected by a first synchronous belt 1. 9. A fourth roller 20 corresponding to the first roller 16 is fixedly installed on the outer surface of the third rotating shaft 15. The first roller 16 and the fourth roller 20 are connected by a second synchronous belt 21. The first roller 16 is connected to an external power source. The rotation of the first roller 16 drives the fourth roller 20 to rotate through the second synchronous belt 21. The fourth roller 20 and the third roller 18 rotate simultaneously. The third roller 18 drives the second roller 17 to rotate through the first synchronous belt 19, thereby realizing the simultaneous rotation of several first lead screws 4. Since the thread direction and rotation direction of several first lead screws 4 are the same, the simultaneous rotation and stopping of the moving plate 5 are realized.

[0036] like Figure 2As shown, two support plates 22 are provided below the top plate 1. The two support plates 22 are symmetrically distributed about the center line of the top plate 1. The support plates 22 are fixedly connected to the third sleeves 206 in the two telescopic components 2 on the same side. The support plates 22 have a rotating groove 23 inside. Several rollers 24 are rotatably installed on the inner wall of the rotating groove 23. The rollers 24 are linearly distributed along the edge of the rotating groove 23. The support plates 22 can make close contact with the ground or other supporting surfaces, providing a stable base for the device. When the device needs to move horizontally, the rollers 24 can significantly reduce the friction between the device and the ground or other contact surfaces. During the installation and debugging of the device, the operator can accurately position and adjust the device according to the position and state of the support plates 22 to ensure that the relative position of the device and the generator stator is accurate, thereby improving the quality and efficiency of stator winding replacement.

[0037] like Figure 7 As shown, the storage rod 12 consists of a main board 25 and several limiting rods 26. Several limiting rods 26 are fixedly installed on the side of the main board 25 near the feeding assembly 9. The limiting rods 26 are linearly distributed along the edge of the main board 25, and a certain interval is formed between each limiting rod 26, so that the stator windings can be neatly arranged on the storage rod 12 in a certain order. The main board 25 has a through slot inside to facilitate the unfolding of the third hydraulic rod 909, so that the operator can easily arrange the stator windings neatly on the storage rod 12.

[0038] like Figures 4-6 As shown, buffer pads 27 are fixedly installed on the sides of the first slider 901 and the second slider 1001 that are close to each other. During the operation of the device, the first slider 901 and the second slider 1001 move relative to each other for various reasons, and then approach each other or even collide. The buffer pads 27 have good elasticity. When the two collide, the buffer pads 27 can absorb and disperse the energy generated by the collision, significantly reducing the impact force.

[0039] like Figure 5 As shown, a vacuum suction tube 28 is fixedly installed on the outer side of the shearing cutter 1006 corresponding to the first electric push rod 1004. During the shearing of the old stator winding, a large amount of debris, such as insulation material fragments and metal wires, will be generated. The vacuum suction tube 28 can use the negative pressure it generates to quickly suck away the sheared debris, keeping the working area clean and providing a good environment for the continuous and stable operation of the device. At the same time, the accumulation of debris inside the device will increase the friction and wear between the components. In particular, for moving parts such as lead screws and guide rails, wear will accelerate their aging and reduce the service life of the device. The vacuum suction tube 28 cleans up the debris in time, reduces the wear between the components, extends the service life of the device, and reduces maintenance costs.

[0040] As shown in the figure, a low-speed motor 29 is installed above the top plate 1 corresponding to the fourth lead screw 202. The output end of the fourth lead screw 202 and the low-speed motor 29 are fixedly connected. A controller is fixedly installed on the upper surface of the top plate 1. Several low-speed motors 29 are electrically connected through the controller. The low-speed motors 29 serve as power devices to provide power for the rotation of the fourth lead screw 202. During the stator winding replacement process, the fourth lead screw 202 needs to drive the telescopic component 2 to extend and retract. The low-speed motors 29 can stably output power to ensure the normal operation of the fourth lead screw 202, enabling the telescopic component 2 to move according to a predetermined trajectory and speed. Through the electrical connection and control of the low-speed motors 29 by the controller, the device can achieve automated operation. The operator only needs to set the corresponding parameters and instructions on the controller, and the device can automatically complete the stator winding replacement process, reducing manual intervention and improving work efficiency and operational accuracy.

[0041] Working principle: After the staff pushes the support plate 22 to move the whole equipment to a suitable position, the staff places the same number of stator windings in the storage rod 12 and places the stator windings on the corresponding limit rod 26 according to the installation sequence.When replacing the stator winding, the fourth lead screw 202 inside the telescopic assembly 2 rotates and pushes the second sleeve 203 through the connecting plate 204. Simultaneously, the connecting plate 204 moves the threaded tube 205, and the fourth lead screw 202 drives the threaded tube 205 to rotate. The rotation of the threaded tube 205 causes the third sleeve 206 to move axially along the threaded tube 205. When the top plate 1 moves to the appropriate position, the fourth lead screw 202 stops rotating. The self-locking mechanism of the threaded tube limits the telescopic assembly 2, allowing the top plate 1 to move to the appropriate height. The first roller 16 rotates and drives the fourth roller 20 to rotate through the second synchronous belt 21. The fourth roller 20 and the third roller 18 rotate simultaneously. The third roller 18 drives the second roller 18 through the first synchronous belt 19. The second lead screw 7 rotates, causing several first lead screws 4 to rotate simultaneously. Since the thread direction and rotation direction of the several first lead screws 4 are the same, the moving plate 5 can rotate and stop simultaneously. The second lead screw 7 rotates, causing the feeding assembly 9 to move away from the replacement assembly 10. Subsequently, the third lead screw 8 cooperates with the first lead screw 4 to move the replacement assembly 10 as a whole above the copper wire on the stator. The second telescopic spindle 1002 unfolds and rotates, causing the shearing cutter 1006 to align with the copper wire. The first electric actuator 1004 unfolds, causing the shearing cutter 1006 to cut the copper wire. The third lead screw 8, the first lead screw 4, and the second telescopic spindle 1002 cooperate with each other, causing the shearing cutter 1006 to cut multiple sets of copper wire in sequence. Subsequently, the second electric actuator 1005 unfolds, aligning the material-retrieving clamp 1007 with the copper wire. The third lead screw 8 and the first lead screw 4 work together to allow the material-retrieving clamp 1007 to remove the copper wire from the stator. The clamp then returns to its original position, and the worker collects the removed copper wire. The third lead screw 8 then rotates to move the clamp away from the feeding assembly 9. The feeding assembly 9 moves to the corresponding position, and the rotating plate 908 rotates via gears. When the material-retrieving plate 910 aligns with the stator winding to be removed, the rotating plate 908 stops rotating. The third hydraulic rod 909 unfolds, allowing the stator winding to enter the material-retrieving plate 910. Simultaneously, the first hydraulic rod 11 unfolds, and the first telescopic main shaft 902 retracts, causing the material-retrieving plate 910 to remove the stator winding. After the rotating plate 908 returns to its original position and the feeding assembly 9 moves to a suitable position, the first telescopic main shaft 902 unfolds, causing the fixed plate 903 to drive the stator winding into the corresponding groove. Rotation aligns the push plate 906 with the groove, and the second hydraulic rod 905 pushes the stator winding into the corresponding groove via the push plate 906. After entering the first groove, the stator winding disengages from the picking plate 910. When placing the stator winding into the second groove, it is first placed in the picking plate 910. Then, the first telescopic main shaft 902 moves and rotates simultaneously, aligning the push plate 906 on the other side with another groove. The second hydraulic rod 905 then pushes the stator winding into the other groove via the other push plate 906.
