The utility model belongs to the technical field of attach angle/sideslip angle sensors and relates to an ice prevention and removal weather vane component. The ice prevention and removal weather vane component is characterized in that the weather vane component comprises an armored electric heater (1), a heater framework, a weather vane shell, a weather vane end cap (4) and rivets (7). Grooves are machined in the heater framework and distributed according to the sensitivity level of an icing area of the weather vane component. The armored electric heater (1) is arranged in the grooves of the heater framework. The heater framework is fixed to the inner surface of the weather vane shell through the rivets (7). The armored electric heater (1) is closely attached to the inner surface of the weather vane shell. The weather vane shell and the weather vane end cap (4) are fixed into a whole. An ice layer covering the surface of a weather vane can be removed in a short time of powering on after ice is formed, the surface of the weather vane can be prevented from being iced up again when the weather vane is powered on continuously, and thus the ice prevention and removal capacity and the safety of the weather vane component are greatly improved.
