Description

Technical Field

[0002] A water turbine is a power machine that converts the energy of water flow into rotational mechanical energy. It belongs to the turbomachinery in fluid machinery. Most water turbines are installed in hydropower stations to drive generators to generate electricity. In a hydropower station, the water in the upstream reservoir is led to the water turbine through a water diversion pipe, which drives the rotation of the water turbine runner and drives the generator to generate electricity. The water that has done work is then discharged downstream through the tail water pipe. The higher the water head and the larger the flow rate, the greater the output power of the water turbine;

[0003] A maintenance platform is a mechanical device that provides a working platform to facilitate the maintenance and repair of high-altitude equipment. It is a composition with excellent characteristics that can make the work safer, more convenient and efficient;

[0004] By installing a maintenance platform in the water turbine unit chamber to repair the water turbine unit and the inner wall of the chamber, however, when assembling the maintenance platform, when the length of the main beam of the maintenance platform is the same as or slightly less than the length of the chamber, assembling the maintenance platform in the chamber is rather cumbersome, and when transporting the main beam of the maintenance platform into the chamber, it is easy for the main beam to collide with the water turbine and the chamber wall.

[0017] By providing a rotatable second main beam, the length of the first main beam can be reduced. After the first main beam and the second main beam move into the chamber, rotate the second main beam to align it with the first main beam, and drive the lifting structure to move upward through the transmission lead screw.
