DEVICE FOR MECHANICAL CLEANING OF BOTTOM IN COOLING POND FILLED WITH WATER AND CASSETTES WITH RADIATED FUEL ASSEMBLIES Russian patent published in 2011 - IPC E02F5/28 

FIELD: construction.

SUBSTANCE: surface part with hoist and accumulators is installed onto flooring above the pond with water. The surface part is connected to the surface part by means of a cord and a cable. The surface part comprises a shaft with two differently directed augers, which are actuated by means of motors connected to shafts. The first vertical shaft is connected to at least one gear, a bevel drive and a horizontal shaft. The second vertical shaft is connected to at least one gear, fixed with the first shaft gear, a bush and a frame. Surface and subsurface parts are connected with the cord with an electric cable wound around it with the possibility for the cord to slide inside the winding. The motor, the bush, gears and vertical shafts are mounted in the cavity of the subsurface part formed by a bed plate tightly fixed to cover.

EFFECT: invention makes it possible to simplify the device design and process of cleaning of stress concentrators from the small sections in the pond bottom.
