When fluid flows through the airfoil, the fluid velocity is different at the airfoil surface, which creates a pressure differential between the upper and lower surfaces, and the force created by this pressure differential is mostly used to provide lift to the aircraft. At the same time, it is noted that the airfoil profile generates additional lift in addition to the normal lift at the near-wall surface due to the influence of the ground effect, i.e. the air below the airfoil at the near-wall surface position has no time to diffuse due to the influence of the near-wall surface, and the pressure below increases. Meanwhile, the positive and negative of the differential pressure of the upper surface and the lower surface can be adjusted by reasonably controlling the positive and negative of the attack angle, namely, the conversion between the lift force and the lower pressure can be achieved by adjusting the attack angle. By adopting the power generation device, the up-and-down movement of the wing profile is realized by utilizing the lift force principle and the ground effect principle of the wing profile in the flow field, and the kinetic energy of the up-and-down movement is converted into electric energy to a certain extent, thereby achieving the purpose of power generation.
The following describes the operation of the power generation device of the present invention in one cycle specifically:
assuming that the airfoil structure 1 starts to operate from the middle and the attack angle is positive, the airfoil structure 1 generates lift force to drive the slide block 201 to move upwards due to the ground effect and the action of the positive attack angle; when the front end connecting rod 104 of the wing profile structure 1 is contacted with the upper arranged accessory outer rod 301 along with the increase of the height, a moment is generated on the wing profile structure 1;
meanwhile, the lateral ratchet block of the pawl 205 is matched with the wedge 307 in the forward direction to open the restraint of the lateral ratchet block of the pawl 205 on the ratchet 103, so that the wing-shaped structure 1 rotates downwards under the action of moment to change into a negative attack angle, but the wing-shaped structure 1 and the slide block 201 still move upwards due to the speed brought by the initial positive attack angle; when the lateral pawl block of the pawl 205 is not contacted with the wedge block 307 any more, the front end of the pawl 205 is embedded between the tooth grooves of the ratchet wheel 103 again to restrict the action of the ratchet wheel 103;
after the downward force generated by the negative attack angle is counteracted with the upward speed, the airfoil structure 1 and the sliding block 201 start to move downward, in the process of moving from the top to the middle, the lateral ratchet block of the pawl 205 is in reverse fit with the wedge block 307, so that the wedge block 307 compresses the spring II 306 downward along the vertical cylinder 305 to move, at the moment, the pawl 205 cannot be opened and restrained due to reverse contact, the attack angle is still negative, and when the lateral ratchet block of the pawl 205 is not in contact with the wedge block 307 any more, the wedge block 307 returns to the original position under the elastic force of the spring II 306.
The connecting rod 104 contacts with the accessory outer rod 301 arranged below the connecting rod at the front end moving downwards to the wing profile structure 1 to generate moment on the wing profile structure 1; meanwhile, the lateral ratchet block of the pawl 205 is matched with the wedge 307 in the forward direction to open the constraint of the pawl 205 on the ratchet 103, so that the wing-shaped structure 1 rotates downwards under the action of torque to change into a positive attack angle, but the wing-shaped structure 1 and the slide block 201 still move downwards due to the speed caused by the negative attack angle; when the lateral pawl block of the pawl 205 is not contacted with the wedge 307 any more, the front end of the pawl 205 is embedded between the tooth grooves of the ratchet wheel 103 again to restrict the action of the ratchet wheel 103;
after the lift force generated by the positive attack angle counteracts the downward speed, the airfoil structure 1 and the sliding block 201 start to move upwards, and in the process of moving from the lowest part to the middle part, the lateral ratchet block of the pawl 205 is reversely matched with the wedge block 307, so that the lower wedge block 307 compresses the spring II 306 upwards along the vertical cylinder 305 to move, and at the moment, the pawl 205 cannot be opened and restrained due to reverse contact, and the attack angle is still positive; when the ratchet block at the side of the pawl 205 is not contacted with the wedge 307 any more, the wedge 307 returns to the original shape under the action of the elastic force of the spring II 306; reciprocating in this way, the generated kinetic energy is finally output as electric energy.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
