Abstract
A high-place observation device for stably performing a fixed-point observation of a target object from a high place is provided. The high-place observation device provides a long pole which is formed to extend and contract freely and which stands on the installation surface, a rotorcraft for positioning the pole to a desirable height position by extending and contracting the pole by a floating force in a connected state, a winding mechanism which fixes and maintains the height position of the pole to the height position set by the rotorcraft, and a camera attached to the rotorcraft.
Claims5
A high-place observation device comprising:
- a base which stands on an installation surface;
- a rod-shaped body formed to extend and contract freely and supported by the base;
- a rotorcraft connected to the rod-shaped body for positioning the rod-shaped body to a desired height position by extending and contracting the rod-shaped body via a floating force generated by the rotation of a plurality of rotary blades in a connected state;
- a coupler configured to couple the rotorcraft to the rod-shaped body and release the rotorcraft from the rod-shaped body;
- a gas balloon connected to the rod-shaped body for positioning the rod-shaped body to a desired height position in collaboration with the rotorcraft;
- a maintaining means for fixing and maintaining the height position of the rod-shaped body at the height position set via the gas balloon and the rotorcraft;
- and
- an observation device attached to the rotorcraft,
- wherein the maintaining means is a winding mechanism comprising:
- a reel formed to rotate freely around an axis;
- and
- a wire which is wound around the reel to be withdrawn from the reel with the extension of the rod-shaped body and wound around the reel with the contraction of the rod-shaped body.
