DEVICE FOR CLEANING OF POINT SWITCH Russian patent published in 2014 - IPC E01H8/02 

FIELD: construction.

SUBSTANCE: device comprises nozzles installed on elements of the point between the frame rail and the switch blade, connected via a supply manifold with a source of compressed air, a three-section air intake chamber placed in front of the entrance to the station, one of sections of which is installed between rails of a rail track, and others accordingly at the right and left side from the rail track, serially connected ice and snow sensor, placed on the elements of the point switch between switch blades, and a processing unit. At the same time the outlet of the air intake chamber by means of the air manifold via a three-way controlled valve is connected to the supply manifold, on the section of which after the valve in close proximity to the point switch there is a Venturi nozzle connected. The inlet valve of each section of the air intake chamber is equipped with a filter. Inlets of the inlet valve control unit via communication interface along a radio channel are connected to the control panel of the duty officer at the station, and the inlet of the unit to control a three-way valve is connected to the outlet of the processing unit.

EFFECT: invention makes it possible to clean the point switch depending on weather conditions, to provide high efficiency of point switch cleaning with rational consumption of energy due to usage of energy of a moving train and Venturi effect.
