Abstract
The invention discloses a mechanical flying bird flying demonstration device, and relates to the field of science and education. The mechanical flying bird flying demonstration device comprises two vertical beams and a crankshaft, wherein a cross beam is erected on the upper parts of the two vertical beams; pulling rods are fixed at the lower part of the cross beam; a suspension shaft seat is mounted at the lower end of each corresponding pulling rod; the crankshaft is mounted on the suspension shaft seats; the two ends of the crankshaft extend into vertical beams at the two sides respectively; a driving motor is installed inside the corresponding vertical beam and provides power for the crankshaft; action driving mechanisms are installed on the crankshaft; and traction ropes are connectedto the corresponding action driving mechanisms, and the lower ends of the traction ropes are connected with corresponding flying birds. The traction ropes are suspended on the crankshaft, the flyingbirds are suspended by the corresponding traction ropes, and when the crankshaft rotates, the traction ropes are pulled to move up and down, so that the flying birds float up and down, and the flyingfloating postures of the flying birds can conveniently observed.
Description
technical field [0001] The invention relates to the field of science and education, in particular to a mechanical bird flight demonstration device. Background technique [0002] Mechanical structures are widely used in production and life. In order to meet the needs of laboratories and popular science museum exhibitions, so that learners and viewers can learn the movement and application of machinery, it is necessary to study some specific mechanical models. [0003] Birds stand on the ground and flap their wings downward in the same direction as the earth's gravitational force. Due to inertia, the air in the lower part of the wings will not immediately follow the downward movement of the wings, so the air pressure in the lower parts of the wings will rise. Also due to inertia, the air in the upper part of the wings The air will not follow the wings down immediately, so the air pressure on the upper part of the wings will be reduced, so that there is a pressure difference be...
