Description

Technical Field

[0001] The utility model belongs to the technical field of hot air balloon top umbrellas, in particular to a pulley buckle for a hot air balloon quick discharge system. Background Art

[0002] Hot air balloons use the buoyancy generated by heating the air inside the balloon to fly. They can be used not only for aviation sports, but also for aerial photography, high-altitude operations, weather detection, stunt photography, tourism, aerial advertising, geological and geomorphological surveying, environmental pollution monitoring, and popular science education for young people. There is an exhaust top hole with a diameter of 3-6 meters on the top of the balloon, and there are multiple mesh belts for limiting. A set of exhaust top parachutes with a diameter larger than the exhaust top hole is designed below the exhaust top hole. The working principle is: when the exhaust top parachute is pulled down, the exhaust top parachute is separated from the exhaust top hole by a certain distance, and the hot air can be discharged from the balloon along the circumferential gap between the exhaust top parachute and the exhaust top hole, and the hot air balloon can be controlled to descend or used for landing and recovery.

[0003] When the existing hot air balloon deflates the top parachute, the top parachute is deflated through the interaction of multiple pull ropes and multiple pulleys. The disadvantage is that multiple pulleys are located on the inner wall of the hot air balloon. When the multiple pulleys cooperate, it is easy for the top parachute to get stuck or fail to deflate, causing a safety accident. Therefore, the utility model proposes a hot air balloon quick-release system with a pulley buckle to solve the above problem. Utility Model Content

When the hot air balloon needs to be lowered after being launched or used for landing and recovery, the pull rope is held at the hanging basket below the hot air balloon and pulled hard. At this time, under the pulling force of the pull rope, the control rope transmits the pulling force to the top parachute through the pulley. The control rope fixing point is in the middle position below. At this time, the contraction of multiple control ropes drives the top parachute to contract. The edge of the top parachute moves along the rope net toward the center of the rope net. With the continuous pulling of the pull rope, the top parachute will gradually contract. As the top parachute contracts, the exposed area of ​​the exhaust top hole will increase. The larger the exposed area of ​​the exhaust top hole, the faster the hot air balloon will descend. The pulley buckle assembly plays a labor-saving role. At the same time, the contraction of the top parachute can be simply operated by relying on the pulley buckle assembly, control rope and pull rope, which is convenient and fast. The pulley buckles are arranged on the inner wall of the top parachute and are distributed in a circular shape. The corresponding number can be set according to actual needs. There will be no jamming or failure of the top parachute to contract due to the coordination of multiple pulleys caused by the pulley being arranged on the inner wall of the hot air balloon.
