Dustpan-shaped inflow channel with excellent hydraulic performance and application method of dustpan-shaped inflow channel

Abstract

The invention discloses a dustpan-shaped inflow channel with excellent hydraulic performance and an application method of the dustpan-shaped inflow channel, and belongs to the technical field of hydraulic engineering pump station. The dustpan-shaped inflow channel comprises three sections, namely a straight inlet section, a dustpan-shaped steering section and a trumpet pipe rectifying section, which are arranged in the water flow direction, wherein all the sections have different geometrical characteristics and effects; a rectifying separator plate is arranged in the middle of the straight inlet section, and an anti-vortex separator plate is arranged in the middle of the dustpan-shaped steering section; the straight inlet section, the dustpan-shaped steering section, the trumpet pipe rectifying section as well as the rectifying separator plate of the straight inlet section and the anti-vortex separator plate of the dustpan-shaped steering section are independent prefabricated reinforced concrete components, are manufactured in a factory, and then are transported to the pump station field for field assembly to form a complete dustpan-shaped inflow channel. The dustpan-shaped inflow channel provided by the invention is excellent in hydraulic performance, simple in application method and suitable for small and medium vertical pump stations, ensures the construction quality of the pump station inflow channel and greatly lowers the requirements for the field construction technology level of the inflow channel.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering pumping stations, and in particular relates to a dustpan-shaped water inlet channel with excellent hydraulic performance and an application method thereof, which is mainly used to guide engineers and technicians in designing and applying a dustpan-shaped water inlet channel, and is essential for ensuring small and medium-sized pumping stations The safe, stable and efficient operation of the system is of great significance. Background technique [0002] The water inlet channel with excellent hydraulic performance is a necessary condition to ensure the safe, stable and efficient operation of the pump in the low-lift pumping station. Due to the complex three-dimensional shape of the inlet channel of the low-lift vertical pumping station, small and medium-sized pumping stations are often limited by the technical level of the construction team, making it difficult for the construc...

AI Technical Summary

Problems solved by technology

Due to the complex three-dimensional shape of the inlet channel of the low-lift vertical pumping station, small and medium-sized pumping stations are often limited by the technical level of the construction team, making it difficult for the construction quality of the in-situ pouring of the inlet channel to meet the design requirements, resulting in most small and medium-sized vertical pumping stations. For a long time, the pump station had to adopt an open water inlet pool with simple shape and poor water flow pattern

Difficulties in the construction of water inlet channels have seriously affected the stable and efficient operation of pump units in small and medium-sized pumping stations, and restricted the improvement of the construction level of small and medium-sized low-lift pumping stations with a large area and a large quantity.
