specific Embodiment approach

[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS: The following is a specific explanation of the structure defined by the present invention with reference to the contents of the drawings in the specification.

[0024] The invention provides a series surge chamber for a hydropower station. The surge chamber is located on the pressure pipe 1 upstream of the powerhouse of the hydropower station. The pressure pipe 1 diverts water to realize the power generation of the hydropower station. It is characterized in that the surge chamber includes more than three A surge chamber unit, the surge chamber unit includes a connecting pipe 2 and a vertical shaft 3, one end of the connecting pipe 2 is connected to the pressure pipeline 1, and the other end of the connecting pipe 2 is connected to the vertical shaft 3, the The adjacent vertical shafts 3 are connected by connecting cylinders 4, and a water communication container is formed between the connecting cylinders 4 and the vertic...

Abstract

The invention relates to a series pressure regulating chamber for a hydropower station. On the basis of a conventional pressure regulating chamber, pressure regulating chamber bodies are connected inseries, the cross sections of the pressure regulating chamber bodies are increased, the pressure regulating performance is improved, the water flow effect due to the water hammer inertia circulates between the pressure regulating chamber bodies and a connecting cylinder, and due to the narrowing effect of the different cross sections, energy consumption is reduced, the water hammer pressure is reduced, and the pressure regulating and stabilizing work of the pressure regulating chamber bodies is facilitated. The series pressure regulating chamber can be increased or decreased as needed, so thatthe pressure regulating chamber bodies with different adjusting performance can be arranged, the distance between the pressure regulating chamber bodies arranged in series can further be adjusted asneeded to improve the regulating performance of the pressure regulating chamber.

Description

technical field [0001] The invention relates to a pressure regulating device for water conservancy projects, in particular to a serial pressure regulating chamber for a hydropower station. Background technique [0002] The pressure pipe is the pipe form used for water diversion of the hydropower station. Because it adopts the pressure pipe flow, it is also called the pressure pipe. During the use of the pressure pipe, it often only bears the water pressure, which is relatively small. When the load is reduced or even fully shed, due to the sudden termination of the diversion flow, the pressure pipe will generate a huge water hammer pressure, that is, the water hammer phenomenon. The water hammer pressure is related to the length of the pressure pipe. The impact pressure will even crush the pressure pipeline, causing the paralysis of hydropower station equipment. [0003] The phenomenon of water hammer was first discovered at the Heimbach Hydropower Station in Germany. D. Th...
