Description

Vertical-lifting flying umbrella with vibrating umbrella wings

The technical field is as follows:

the invention relates to an aircraft device which can vertically take off by utilizing the vibration of an umbrella wing and without utilizing the rotation of a propeller to push air to generate lift force.

Background art:

the existing helicopter taking off vertically utilizes the rotation of the propeller to push air to generate lift force so as to take off and hover or fly in the air, and the device has the defects that when the helicopter takes off or hovers in the air, the propeller stops rotating due to faults, the helicopter loses the lift force and crashes, and the safety is poor.

The invention content is as follows:

the invention aims to provide an aircraft device which is high in safety compared with the prior art and can take off vertically without using a propeller to rotate and push air to generate lift force. In order to achieve the purpose of the invention, the invention utilizes seven same umbrella wings, one group of three umbrella wings and two groups of umbrella wings are respectively arranged on two umbrella rods, and one umbrella wing is used as a spare umbrella wing and is arranged on the outer wall of a guide pipe of a crank case. The two umbrella rods are in a circular tube shape, one umbrella rod is slightly larger in diameter, the other umbrella rod is slightly smaller in diameter, and the other umbrella rod is inserted into the other hole cavity and can slide up and down mutually. Then the umbrella pole with large diameter is inserted into the conduit hole cavity of the crankcase, and the umbrella pole with large diameter can slide up and down in the conduit hole cavity. Each umbrella wing is composed of forty-eight same wing arms and forty-eight same wing pieces, the cross sections of the wing arms are of T-shaped structures so as to enhance the stress intensity, the wing arms are provided with wing piece shaft seats, and the wing piece shafts are mounted on the shaft seats. Each wing is triangular, a round pipe is arranged on one edge of each triangular wing and can be sleeved on a wing shaft of a wing arm, every two wings are in a group and are jointly installed on the wing shaft of the same wing arm, and the adjacent wing arm is not provided with a wing and only provides a supporting effect for the wings. Each wing can rotate on the wing shaft in a reciprocating way of 80 degrees. Each wing arm is uniformly and fixedly arranged on an annular wing arm seat by a welding method, and the wing arm seats are sleeved on the umbrella rod and fixedly connected by bolts. The same tension rib is arranged below each wing arm, one end of each tension rib is fixedly connected with the wing arm through a bolt, and the other end of each tension rib is fixedly connected with the tension rib seat through a welding method. The tension rib seat has the same shape and structure as the annular wing arm seat and is fixedly arranged on the umbrella rod by bolts. The crank shaft is arranged in the crank case, the crank shaft is arranged in the crank case through a bearing and can flexibly rotate, and two connecting rods are arranged on the crank shaft and are respectively connected with two umbrella rods. The big ends of the two connecting rods are connected to the crankshaft through bearing bushes and can flexibly rotate, and the two connecting rods are respectively connected to the umbrella rods through umbrella rod pins and can flexibly rotate. The part of the crankshaft, which extends out of the shell of the crankcase, of the crankshaft is provided with a belt pulley and is connected with a belt pulley on a power output shaft of a power machine device through a belt. The crankcase is internally provided with a small-sized oil pump which is connected with the crankshaft through a gear. When working, the oil pump delivers the oil in the crankcase to the moving parts through the oil channels arranged on the crankcase shell, the crankshaft, the two connecting rods and the guide pipe of the crankcase so as to provide lubrication. The crankshaft connecting rod mechanism, the umbrella rod and connecting rod mechanism and the lubricating mechanism of the invention have the same technical structure principle as the crankshaft connecting rod mechanism, the piston connecting rod mechanism and the lubricating mechanism of the existing internal combustion engine. The power machine device is arranged under the base of the crankcase through a bolt, and the power machine device is connected with the cab through a bolt under the base. The power machine device is provided with two power output shafts, one shaft is provided with a belt pulley which is connected with a crankshaft belt pulley through a belt, and the other shaft is connected with a rotating shaft of a propeller arranged outside a cab through an elastic coupling. The clutch devices are arranged on two power output shafts of the power device, and the two clutches are controlled by two clutch handles in the cab. A steering rudder device is also arranged outside the cab, and a steering handle in the cab can control the steering rudder. Three small holes are arranged on the wing arm seat and are uniformly distributed on the same circumference, so that the flying umbrella can be ensured to be stable and not to swing during movement.

When the power machine works, the power machine device provides power for a crankshaft in a crankcase through a belt, and two connecting rods on the crankshaft respectively drive two umbrella rods to move up and down. The two umbrella rods continuously vibrate in opposite directions. When the wings on the two umbrella rods move upwards, all the wings rotate 80 degrees from a flat state, the wings are opened, and the air resistance on the wings is small. When moving downwards, all the wing plates rotate upwards by 80 degrees to restore the flat state, the umbrella wings are closed, and the umbrella wings are acted by the great upward reaction force of air, so that the flying umbrella can be pushed by the lift force to take off. The mutual matching mode of the two fins of each group is the same as the structure of a common hinge for mounting doors and windows, so that the technical performance that the two fins of each group form an included angle of 20 degrees after being respectively turned down by 80 degrees from a flat state is ensured, and the two fins can be flexibly opened under the pushing of air when moving downwards. The power of the power machine is controlled, so that the ascending height of the flying umbrella can be controlled. Then when the power machine is used for providing power for the propeller through the clutch handle, the flying umbrella can move in the air under the pushing of the propeller, and the steering rudder can control the flying direction. After the parachute is lifted off, if the power system is closed or fails, the parachute can slowly descend like a parachute. When the umbrella wings on the umbrella rod are damaged due to work, the standby umbrella wings can provide a safety protection effect to ensure that the flying umbrella slowly descends without crashing. Three small holes which are uniformly distributed on the same circumference line are arranged on the wing arm seat, so that the flying umbrella can be ensured to be stable and not to swing when in motion.

Compared with the prior helicopter technical device, the helicopter with the vibrating umbrella wings has the advantages that the two groups of umbrella wings generate lift force by reciprocating vibration, the propellers do not need to be used for rotating and pushing air to generate the lift force, so the helicopter can take off vertically, and the helicopter can slowly descend like a parachute without crashing when a power system is closed or fails, and the helicopter has simple structure and high safety.
