Description

Technical Field

[0001] This utility model relates to the field of generator maintenance technology, and in particular to a hydropower station generator stator maintenance platform. Background Technology

[0002] The stator of a hydroelectric generator is an important component of the generator. Its main function is to generate alternating current. The stator is installed outside the rotor and fixed to the front and rear end covers of the generator. When the rotor rotates inside, it causes changes in the magnetic flux in the stator windings, thereby generating an alternating induced electromotive force in the stator windings. The stator is the stationary part of the generator, and its function is to generate voltage by cutting the magnetic field. The performance of the stator directly affects the safe and stable operation of the generator set. The stators of large hydroelectric generators often adopt a segmented structure, so a maintenance platform is needed for rapid maintenance to improve the convenience and stability of inspection.

[0003] For example, application number CN202120576616.9 discloses a hydropower station generator stator maintenance platform, including a support frame with a first guide rail in the horizontal direction and a second guide rail in the vertical direction; a maintenance platform installed on the horizontal surface of the support frame for maintenance personnel to walk on; a support platform with a drive device to drive the support platform to slide on the first guide rail; and a lifting device including a motor, pulleys, and a pull rope. The motor and pulleys are fixedly installed on the support frame, and the pull rope passes around the pulleys and connects to the top of the support platform. The motor pulls the support platform up and down on the second guide rail by winding the pull rope, thus lifting it onto the maintenance platform. This hydropower station generator stator maintenance platform facilitates the movement of maintenance tools and large maintenance equipment to the maintenance platform, enabling maintenance personnel to perform maintenance on the hydropower station generator stator.

[0004] Based on the above and the common hydropower station generator stator maintenance platforms on the market, they usually rise to the top for maintenance, which has a relatively limited maintenance height, low flexibility, blind spots, and a distance from the stator during maintenance, making it inconvenient to approach and maintain, thus limiting maintenance efficiency. Utility Model Content

[0005] This disclosure relates to a hydropower station generator stator maintenance platform. Its displacement structure can be rotated and moved above the moving components by a controller, improving the convenience of maintenance. During maintenance, if the displacement structure is far from the hydropower station generator stator, the electric cylinder can be controlled to move, causing the electric cylinder to push the baffle structure to move. The baffle structure moves together through the pull rod and the blocking rod, causing the baffle structure to automatically adjust its position and move closer to the hydropower station generator stator, so that the staff can step on the blocking rod to carry out maintenance, improving maintenance efficiency.

[0006] In a first aspect, this disclosure provides a hydropower station generator stator maintenance platform, specifically comprising: a movable component; the top of the movable component is provided with a guide structure, the side of the movable component is connected to a connecting block via a connecting plate, the connecting block is slidably connected to a support rod assembly, there are six support rod assemblies in total, the six support rod assemblies control the vertical displacement of the movable component, wherein the top of three support rod assemblies is fixed with a winch for controlling the vertical movement of the movable component; a displacement structure; the displacement structure is installed above the movable component to guide its rotational movement, the displacement structure is provided with a controller for controlling displacement, the inner bottom of the displacement structure is rotatably connected to a pull rod and a stop rod via a control groove and a pull groove, the inner ends of the pull rod and the stop rod are connected to a baffle structure, and the arc-shaped baffle structure can be spliced ​​onto the inner side of the displacement structure.

[0007] In at least some embodiments, the movable component is integrally formed with a connecting plate on its exterior. The bottom of the connecting plate is connected to the connecting block by bolts, and the support rod assembly extends freely through the connecting block. The top of the connecting block is provided with a U-shaped splicing block assembly, which is embedded inside the bottom of the connecting block.

The positions of the force-bearing components correspond to the positions of the winch and are driven to move by the winch. The bottom of the support rod assembly is fixedly connected to the base piece, which is fixed by bolts.

[0008] In at least some embodiments, a guide plate structure is fixed on the upper sides of the inner sides of the displacement structure, and an L-shaped control groove is opened at both ends of the bottom inner side of the displacement structure. The pull rod is inserted into the control groove and can be pulled freely. The bottom inner side of the displacement structure has evenly arranged pull slots, and a blocking rod is inserted into the pull slot and can be pulled freely.

The outer end of the electric cylinder is connected to the baffle structure and drives the baffle structure to move laterally. A sliding rod structure is fixed on both sides of the top of the baffle structure, and the sliding rod structure is slidably connected to the guide plate structure.

[0009] This utility model provides a hydropower station generator stator maintenance platform, which has the following beneficial effects:

[0010] When in use, the moving component moves together with the displacement structure. When maintenance is required, three winches can be controlled to operate simultaneously, allowing the moving component to move freely up and down outside the generator stator of the hydropower station. Depending on the usage requirements, the moving component and displacement structure can be controlled to be at an appropriate height, enabling maintenance personnel to perform maintenance at an appropriate height, improving the flexibility and convenience of maintenance, avoiding blind spots in maintenance, and reducing operating costs.

[0011] The displacement structure can be rotated and moved above the moving components by the controller, improving the convenience of maintenance. During maintenance, if the displacement structure is far from the stator of the hydropower station generator, the electric cylinder can be controlled to move, causing the electric cylinder to push the baffle structure to move. The baffle structure moves together through the pull rod and the blocking rod, causing the baffle structure to automatically adjust its position and move closer to the stator of the hydropower station generator, so that the staff can step on the blocking rod to carry out maintenance, improving maintenance efficiency.
