Embodiment Construction
[0016] The underground powerhouse of the present embodiment has No. 1, No. 2, No. 3, and No. 4 four generator sets, and the drainage system includes an overhaul drainage system and a seepage drainage system.
[0017] like figure 1 As shown, the inspection and drainage system of this embodiment is provided with an inspection drain 2 at the lower part of the draft tube of each generator set 1, and each drain is connected with a closed drainage system 1 through a ball valve 3, and the closed drainage system 1 is passed through The outlet pipe 111 communicates with the drainage corridor 4, which is generally located in a higher mountain body, and the water is discharged into the safe area by gravity. This closed drainage system 1 is also communicated with the seepage sump 5 through the isolation valve 22 through the inlet pipe 222 .
[0018] The closed drainage system 1 of this example includes two sets of drainage devices with larger capacity, and each set of drainage devices in...

The invention relates to a discharge structure of an underground factory. The invention aims at always closing the reservoir water in a discharge system and pumping the water out of the factory when overhauling a machine set by adopting the mode of combining mechanical discharge and automatic flowing discharge, and leading the leakage water in the factory to be discharged out of the factory by an indirect mode. The technical proposal thereof is as follows: an overhauling discharge system is provided with overhauling discharge ports at the lower parts of the tail water pipes of each electric generating set; each discharge port is connected with a closed discharge system I through a ball valve; the closed discharge system I is communicated with a discharge gallery through an outlet pipeline; the closed discharge system I is also communicated with a leakage collection well by an isolating valve through an inlet pipeline; while the leakage discharge system is communicated with a leakage discharge gallery in the factory at the lower part of the leakage collection well and the closed discharge system II is arranged on the mouth of the leakage collection well. The water outlet of the closed discharge system II is connected to the discharge gallery arranged at the higher position of a hill through a water pipe. The discharge structure of underground factory is applicable to the discharge of the underground factory.
Description
technical field [0001] The invention relates to a drainage structure of an underground factory building. It is suitable for drainage of underground powerhouses, such as underground powerhouses of hydropower stations, drainage of underground buildings, etc. Background technique [0002] Taking the underground powerhouses of hydropower stations as an example, with the vigorous development of my country's hydropower industry, many giant power stations and pumped storage power stations have adopted the layout of underground powerhouses. Because the underground plant is buried deep underground, the safe operation of the equipment in the plant is very important, especially the drainage system of the underground plant must be reliable, which is the basic requirement for the safe operation of the equipment in the underground plant. Once a factory building accident occurs due to flooding, the direct / indirect losses will be very heavy. For example, some power plants in China have ex...
