Title:
ANTI-ICING AND DEICING DEVICE BASED ON SUDDEN CHANGE IN CENTER OF GRAVITY, SPACER, SYSTEM, AND ANTI-GALLOPING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/093066
Kind Code:
A1
Abstract:
The invention relates to the technical field of anti-icing and deicing of overhead power transmission lines or railway catenaries, and provided are a mechanical anti-icing and deicing device fixedly installed on a overhead power transmission line or a railway catenary. The present device comprises a base and an electric drive assembly, a weight block, and a potential energy module comprising an elastic element all arranged on the base. The electric drive assembly comprises a clutch mechanism and a motor. When the clutch mechanism is in an engaged state, the electric drive assembly drives the weight block to be displaced relative to the base, and when the clutch mechanism is in a separated state, the electric drive assembly severs the driving of the weight block. While the clutch mechanism is engaged, the potential energy module is used for accumulating potential energy when the weight block is displaced relative to the base; when the clutch mechanism is separated, the driving force of the electric drive assembly on the weight block is severed, and potential energy contained in the potential energy module is rapidly released, causing the weight block to quickly move, thereby causing overall center of gravity of the present device to suddenly change, generated vibrations are transferred to overhead power transmission lines, and ice is removed.
