They are crucial for fully utilizing clean and renewable energy to achieve energy conservation, emission reduction, and environmental pollution reduction. Most water turbines are installed in hydropower stations to drive generators to generate electricity. In a hydropower station, water from the upstream reservoir is drawn to the water turbine through a water intake pipe, which drives the turbine runner to rotate and drives the generator to generate electricity.
[0003] For example, CN214118369U discloses a turbine maintenance platform, relating to the field of turbine technology. This turbine maintenance platform includes a wide tailpipe located below the turbine's tailrace. The wide tailpipe includes a platform and a wide pipe positioned below the platform. A maintenance manhole is provided on the platform, leading into the wide tailpipe. An annular reinforcing platform is located at the constriction point in the middle of the wide pipe. A protective plate is provided on the reinforcing platform, connecting to the top of the wide pipe. A ladder is slidably connected to the reinforcing platform. The ladder is driven by a pushing mechanism to move radially along the wide pipe. The ladder is evenly distributed around the inner cavity of the tailrace and is vertically arranged. An mounting rod for installing a mounting plate is provided near the top of the ladder. A chain connects the ladder to the inner wall of the tailrace. This utility model solves the problem of constructing a maintenance platform for periodic turbine maintenance by incorporating a wide tailpipe, a reinforcing platform, a ladder, a pushing mechanism, a mounting plate, and mounting rods.
