Due to inertia, in the starting stage, even if the frequency and amplitude of the up-and-down push-pull mechanism are not changed, the blades can rotate faster and faster as long as a certain frequency and amplitude are kept. After starting, within a certain rotating speed range, the amplitude of the up-down push-pull is fixed, and the faster the frequency of the up-down push-pull is, the faster the blade rotates; the frequency of the up-down push-pull is fixed, and the larger the amplitude of the up-down push-pull is, the faster the blade rotates. The resistance that the blade moved ahead can increase along with the increase of rotational speed, but when the blade rotated the back, along with the quick increase of the rotatory speed of blade, the reynolds number of blade can increase, and then the acceleration rate of the resistance that the blade moved ahead can slow down, if experience person with strength push-and-pull rod, the blade can high-speed rotation. If the frequency or amplitude of the push-pull decreases, the rotational speed of the blades slows down. The force changes in the whole pushing and pulling process, and is not stiff like the traditional fitness equipment. The up-and-down movement not only overcomes the gravity of the push-pull mechanism and the rotating vane device to do work, but also overcomes the resistance of the rotating surface of the vane to the air movement to do work. Therefore, when the rotating vane device moves downwards, if the resistance of the rotating surface of the vane to the movement of air is greater than the gravity of the push-pull mechanism and the rotating vane device, the rotating vane device can move downwards quickly only by pulling the push-pull mechanism downwards with force. Therefore, the user can have pleasurable experience and achievement feeling, the feeling is comfortable and interesting, the entertainment and body building effects can be achieved, the user can take exercise in pleasure, and the physical and mental health of people is benefited. Of course, the movement process of the blades is a very complicated process, and the multiple movements of forward movement, upward movement and downward movement are combined together and are influenced by the local environment such as wind speed and wind direction. Here a simple analysis is made using classical fluid mechanics. The inventor of the scheme proves the motion process through a plurality of physical prototypes: the handle is pushed and pulled up and down rapidly, so that the blade can rotate rapidly towards the front edge, and the experience person feels pleasure.

The basic working principle of the rotary vane body builder of the utility model is as follows: an experiencer holds the handle to quickly push and pull the push-pull mechanism 2 up and down, under the traction of the push-pull mechanism 2, the rotating vane device 1 moves up and down, the upper surface 113 of the vane and the lower surface 114 of the vane are windward alternately, at least one surface of the upper surface 113 of the vane and the lower surface 114 of the vane is convex, the maximum thickness position of the wing profile of the vane 11 is close to the front edge 111 of the vane and far away from the rear edge 112 of the vane, the head-on incoming flow acts on the convex surface of the wing profile and is divided into two air flows with different sizes, the small air flow moves towards the front edge 111 of the vane, and the large air flow moves towards the rear edge 112 of the vane, so that a momentum difference is formed between the front edge 111 of the vane and the rear edge 112 of the vane, the air flow pushes the vane 11 to move towards the front edge 111 of the vane, and the vanes 11 rotate around the inner ring of the bearing 12 under the action of thrust and inertia. Due to inertia, the blades 11 will rotate faster and faster during the start-up phase, even if the frequency and amplitude of the push-pull mechanism 2 is not changed, as long as a certain frequency and amplitude is maintained. After starting, within a certain rotating speed range, the amplitude of the up-down push-pull is fixed, and the faster the frequency of the up-down push-pull is, the faster the blade 11 rotates; when the frequency of the up-and-down push-and-pull is constant, the larger the amplitude of the up-and-down push-and-pull is, the faster the blade 11 rotates. The resistance of the blade 11 to move forward increases with the increase of the rotation speed, but after the blade 11 rotates, the reynolds number of the blade 11 increases with the rapid increase of the rotation speed of the blade 11, and the increase of the resistance of the blade 11 to move forward slows down, and if the experiencer pushes and pulls the push-pull rod 21 hard, the blade 11 rotates at a high speed. If the frequency of the push-pull decreases or the amplitude decreases, the rotational speed of the blades 11 will slow down. The force changes in the whole pushing and pulling process, and is not stiff like the traditional fitness equipment. The up-and-down movement not only overcomes the gravity of the push-pull mechanism 2 and the rotating vane device 1 to do work, but also overcomes the resistance of the rotating surface of the vane 11 to the air movement to do work. Therefore, when the rotary vane device 1 moves downwards, if the resistance of the rotating surface of the vane 11 to the air movement is larger than the gravity of the push-pull mechanism 2 and the rotary vane device 1, the push-pull mechanism 2 needs to be pulled downwards by force to enable the rotary vane device 1 to move downwards rapidly. Therefore, the user can have pleasurable experience and achievement feeling, the feeling is comfortable and interesting, the entertainment and body building effects can be achieved, the user can take exercise in pleasure, and the physical and mental health of people is benefited. Of course, the movement process of the blade 11 is a complicated process, and the multiple movements of forward movement, upward movement and downward movement are combined together and also influenced by the local environment such as wind speed and wind direction. Here a simple analysis is made using classical fluid mechanics. The inventor of the scheme proves the motion process through a plurality of physical prototypes: the rapid up and down reciprocation of the push handle causes the vanes 11 to rotate rapidly in the direction of the leading edge and the experience will be pleased.
