Deployment and flying device for flags

Abstract

The invention provides an unfolding and waving device for a flag. The unfolding and waving device consists of a flag pole base, a main flag pole, an auxiliary flag pole and a flag, wherein a fixed pulley is arranged at the top of the main flag pole; a flag hoisting winch mechanism, a flag falling winch mechanism and an air supply system are arranged in the flag pole base; the flag hoisting winch mechanism is connected with the top end of the auxiliary flag pole through a flag hoisting rope with one end bypassing the fixed pulley; the flag falling winch mechanism is connected with the lower end of the auxiliary flag pole through a flag falling rope; a flag rope tube is arranged at the upper edge of the flag; the air supply system communicates with one end of the flag falling rope through a winding drum spindle in the flag falling winch mechanism and conveys air into the flag falling rope; the other end of the flag falling rope is connected with the lower end of the auxiliary flag pole; the upper end of the auxiliary flag pole is perpendicularly connected with one end of the flag rope tube; the air in the flag falling rope enters the flag rope tube through the auxiliary flag pole; the air in the flag rope tube is uniformly and downwards sprayed out to hoist the flag under the counter-acting force of the air to realize unfolding and waving. The unfolding and waving device for the flag simulates a dynamic effect that the flag is blown by natural wind to wave, so that the flag can achieve a naturally unfolding and waving effect in a flag hoisting process under an environment without wind and the like.
