About the Possibility of Using Vibrations to Remove Snow From a Sloping Roof

Abstract

<jats:p>Timely removal of snow from the roof ensures the absence of ice and icicles, which contributes to the safety of roofing material and guarantees the safety of people's lives. Various mechanical methods of snow removal from pitched roofs are considered. Various devices and units for snow dumping by means of vibrations are analyzed. A useful model "device for removing snow and ice from an inclined roof"is presented. The device contains an electric motor, a transmission in the form of a rotating shaft with an eccentric placed in the housing on bearings. At least one sole is attached to the body in the form of a plate for fastening the body to the crate or rafters. The motor is powered by a battery or charger. Tests of the device, carried out first on model, and then real roofs, showed that vibrations can be successfully used for snow removal from pitched roofs. The most rapid removal of snow occurs from the roofs with metal, and with painted profiled faster than galvanized. Rough roofs (slate, Ondulin) snow melts more slowly, and with oculina faster due to the smaller mass per square meter of roofing material and more amplitudoi its vibration. It is established that it is most effective to fix the device with the axis of rotation parallel to the rafters and to the Board of the crate to which the roofing material is sewn. Useful model "device for removing snow and ice from a sloping roof" has proven to be reliable in operation, easy to manufacture, mobile and efficient. The device allows you to clean the snow without leaving the person on the roof.</jats:p>
