Description

Technical Field

[0001] The invention belongs to the technical field of rotating trays, and relates to a rotating tray for steel pipe installation, in particular to a rotating tray for penstock installation in a pumped-storage power station. Background Art

[0002] The penstock of a pumped-storage power station is a key component connecting the reservoir and the generator. Its main function is to convey water to drive the turbine for power generation. These pipelines not only bear huge water pressure, but also ensure the safety of water quality and the stable operation of the system. The penstock is responsible for conveying the water in the reservoir to the underground powerhouse where the generator is located, ensuring that the water pressure is within a reasonable range to guarantee the power generation efficiency, having good sealing performance to prevent water leakage and ensuring the safety of the power station.

[0003] During the installation of the penstock in a pumped-storage power station, due to the limited space in the tunnel, the direction of the pipe orifice is inconsistent with the installation direction after the steel pipe is unloaded from the vehicle. It is necessary to adjust the direction of the penstock. Currently, the rotation of the penstock is supported by a rotating tray for adjustment. However, the current rotating tray has a simple structure and lacks the limit and fixation of the steel pipe, resulting in easy sliding and even tilting during the adjustment. In view of this, we designed a rotating tray for penstock installation in a pumped-storage power station. Summary of the Invention
