2results about How to "Efficient deicing" patented technology

The invention discloses a deicing device and application thereof, the deicing device comprises a vibration assembly and a driving assembly, the vibration assembly comprises a first eccentric block and a second eccentric block, and a driving part is connected with a first rotating shaft and a second rotating shaft through a steering part to drive the first rotating shaft and the second rotating shaft to coaxially and reversely rotate. Meanwhile, the first eccentric block is connected with the second rotating shaft, and the second rotating shaft drives the first eccentric block to rotate around the axial center of the second rotating shaft. The second eccentric block is connected with the first rotating shaft which drives the second eccentric block to rotate around the axial center of the first rotating shaft. As the first rotating shaft and the second rotating shaft coaxially and reversely rotate, the first eccentric block and the second eccentric block are respectively driven to coaxially and reversely rotate. The first eccentric block and the second eccentric block drive the deicing device to vibrate in the reverse rotation process, so that the overhead transmission line coated with ice vibrates at the same time, ice blocks or frost layers are shaken off, and efficient deicing is achieved.

This invention provides a protective de-icing membrane, a protective de-icing component and system, wind turbine blades, and a wind turbine generator set. The protective de-icing membrane includes a heating layer and a covering layer. The heating layer includes a heating pipe, a heating medium inlet, and a heating medium outlet. The heating medium enters the heating pipe through the heating medium inlet and exits from the heating pipe through the heating medium outlet. The covering layer covers at least a portion of the heating layer. The protective de-icing membrane according to this invention can improve de-icing efficiency and reduce energy consumption.
