ENERGY-EFFICIENT DRAINAGE SYSTEM Russian patent published in 2025 - IPC E04D13/64 

FIELD: construction.

SUBSTANCE: invention relates to the field of construction, in particular to the buildings roofs drainage systems structures. Essence of the technical solution consists in the fact that the energy-efficient drainage system includes a drainage pipe and electric heating elements, wherein electric heaters are arranged under heat-insulating material layer that makes a single channel. Drain pipe at least in two places along its length is rigidly connected with brackets pivotally mounted on posts fixed on roof slope under cover material and supported by tension-compression spring, wherein said supports are provided with microswitches to interact with contacts of power supply system arranged on the side of cover material. Microswitches are connected to heating elements arranged in drain pipe in shell of heat-insulating material. At that, arrangement in drain pipe of heating elements in shell from heat-insulating material at different value of electric load allows to remove ice cover and snow cover at minimum possible electric power consumption.

EFFECT: use of the proposed energy-efficient drainage system makes it possible to automatically track the occurrence of a dangerous load on the pipe in case of precipitation in the form of snow or ice formation.
