Anti-flooding drainage system for underground workshop of pumped storage power station

Abstract

The invention discloses an anti-flooding drainage system for an underground workshop of a pumped storage power station. The anti-flooding drainage system comprises a leakage water collecting well arranged in the underground workshop of the pumped storage power station and a submersible deep-well pump arranged in the leakage water collecting well; the submersible deep-well pump is connected with aleakage drainage main pipe connected to an original leakage drainage system through a drainage pipe, and the leakage drainage main pipe finally drains water out of the workshop; and a body cable arranged in the submersible deep-well pump is led out of the well through the leakage water collecting well and connected with a main power supply cable through a waterproof cable intermediate joint, and the main power supply cable is connected with a water pump power supply and distribution room located on the ground outside the workshop. The anti-flooding drainage system has the anti-flooding characteristic, the problem that a drainage system in the underground workshop cannot normally work due to loss of a power supply in the workshop when the workshop is flooded by water can be solved, rapid elimination of accidents is facilitated, and the emergency drainage capacity of the pumped storage power station is improved.

Description

technical field [0001] The invention relates to an anti-flooding and drainage system for an underground workshop of a pumped storage power station, which is suitable for the pumped storage power station and other underground spaces requiring anti-flooding and drainage, and belongs to the technical field of the pumped storage power station. Background technique [0002] The powerhouse of a pumped storage power station is generally in the form of an underground powerhouse, and it is usually located tens of meters below the ground. Underground powerhouses are generally equipped with seepage collection wells and leakage drainage systems. The power supply of the leakage drainage system is supplied by the utility power system located in the underground powerhouse. This system can eliminate the leakage water generated during the normal operation of the power station. However, in the event of an abnormal water-flooded plant accident beyond the original design conditions, such as cra...
