Embodiment Construction

[0030] The present invention will be specifically described below in conjunction with the accompanying drawings.

[0031] figure 1 Shown is a schematic diagram of the spanwise arrangement of the deicing device on the UAV. It can be seen from the figure that the deicing device is arranged on the leading edge of the wing 1 of the UAV along the span direction.

[0032] Figure 4-8 The specific structure of the deicing device is shown. The deicing device includes a servo steering gear 2, and a steering gear rocker arm 6 is provided with a steering gear rocker arm 6. The steering gear rocker arm 6 is fixed on the output shaft of the steering gear 2, and it can move in a circle with the output shaft as the center. The steering gear rocking arm 6 is connected with a steering gear connecting rod 3, and the other end of the steering gear connecting rod 3 is connected with the ice bar 5. Like this, the steering gear rocking arm 6, the steering gear connecting rod 3, and the ice bar 5...

Abstract

The invention discloses an aerofoil leading edge deicing device for an unmanned aerial vehicle, which comprises a servo steering engine, a pushing mechanism and an ice pushing strip, wherein the pushing mechanism pushes the ice pushing strip under the drive of the servo steering engine; the ice pushing strip is protruded out of the skin surface of an aerofoil of the unmanned aerial vehicle after being jacked up for carrying out deicing work; the pushing mechanism comprises a steering engine rocking arm and a steering engine connecting rod; the steering engine rocking arm is fixed on an outputshaft of the servo steering engine and can do circular motion by adopting the output shaft as a circle center; one end of the steering engine connecting rod is connected to the steering engine rocking arm, and the other end is connected with the ice pushing strip; and the steering engine rocking arm, the steering engine connecting rod and the ice pushing strip form a crank rocker mechanism, and the steering engine connecting rod drives the ice pushing strip for realizing jacking up and retracting motions. The aerofoil leading edge deicing device for an unmanned aerial vehicle has simple structure, low cost, safety, reliability, convenient operation and recycling.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicle systems, in particular to a novel wing leading edge deicing device for unmanned aerial vehicles Background technique [0002] A drone is a powered, unmanned aircraft.
