Leakage-proof system for underground cooling pool of boiler

The utility model discloses a boiler underground cooling pool leakproof system which comprises a cement pool, a water storage tank, a water pump and a PLC (programmable logic controller), a plurality of metal plates are laid and covered on the inner wall of the cement pool, adjacent metal plates are welded in a sealing manner, and a plurality of ground anchors arranged on the inner wall of the cement pool are fixed on the back of each metal plate. The cooling pool has the advantages that high-temperature wastewater can be prevented from directly affecting the inner wall of the cement pool by arranging the metal plate inner cavity, the water guide groove formed in the back face of the metal plate and the inner wall of the cement pool form the heat exchange cavity, the temperature of the high-temperature wastewater subjected to heat exchange is greatly reduced, the expansion deformation of the metal plate is reduced, and the sealing performance and stability of the cooling pool structure are guaranteed; in addi
