Power plant river bed water intake device

Abstract

The invention discloses a water intake device for a river bed of a power plant, which includes a water inlet, a storage tank and a water intake pump room, the storage tank is arranged between the water inlet and the water intake pump room, and the water inlet and the water intake pump room The adjustment and storage tank is connected, and a grit settling area is provided near the water inlet in the adjustment and storage tank, and the grit settling area is in communication with the adjustment and storage tank. The river bed water intake device of the power plant is provided with a storage tank between the water inlet and the water intake pump room, and the water flowing in from the water inlet will first enter the storage tank, and the water storage capacity of the storage tank is guaranteed during application to meet the needs of the power plant. Long-term continuous water supply safety requirements; and by setting up a sand settling area, the raw water taken from the water inlet can be pre-sedimented at the first time, which greatly improves the quality of the raw water entering the storage tank and the subsequent water intake pump room during the flood period. Reduce the difficulty of overall cleaning and maintenance of the water intake device. During maintenance, it is only necessary to focus on cleaning the sand settling area.

Description

technical field [0001] The invention relates to the technical field of power plant construction, in particular to a water intake device for a river bed of a power plant. Background technique [0002] Water is the "blood" flowing in a power plant. How to choose an economical and reasonable water intake plan according to local conditions according to the type of water source, the location of the water source, and the quality of the water source is one of the most noteworthy contents in the hydraulic design of the power plant. At present, the construction of power plants puts forward higher requirements for the safety of water supply for continuous multi-days. The water sources of countries such as Southeast Asia are mostly affected by floods, the rainy season is long, the water quality is poor during the water supply period, and the sediment content is high. At present, the water intake scheme that directly diverts water from the water intake to the water intake pump room thr...

Problems solved by technology

At present, the water intake scheme that directly diverts water from the water intake to the water intake pump room through pipelines, open channels, box culverts, etc. is mostly adopted. The safety of water supply is only controlled by 97% dry water level, 99% dry water level, etc. Therefore, how to set Safe and reliable water intake device is a topic worthy of attention and research
