Specifically, the sea surface of the sea fluctuates up and down along with the wind waves, the floating balls move up and down under the excitation of the sea waves so as to drive the gear racks to work, and the rotation of the gears drives the ratchet wheel and pawl system to work so as to tighten the clockwork spring of the tourbillon structure.

Specifically, the tourbillon structure includes clockwork spring device, gear drive, escapement device, base support. The working principle is as follows: energy is input to the spring under an external force, and after winding the spring, the spring has a tendency to come loose, and the barrel therefore rotates. The spring box rotates to drive the gear to rotate. The gear eventually drives the escape wheel to rotate, but the escape wheel is an intermittently rotating mechanical component, the motion state of which is controlled by the pallet.

Further, the tourbillon mechanism comprises a spring 14, a spring stem 27, a mainspring 19, a ratchet 16, a barrel gear 15, a ratchet spring 26, a barrel pawl 25, a transmission gear 3, an escape wheel 4, a pallet fork 24, a striker housing 21, a balance spring 22, a bracket (20, 17, 18, 23, 9, 10, 11); the clockwork spring 14 is connected with the ratchet wheel 16 through a clockwork spring rotating handle 27; the main spring 19 is sleeved on the ratchet shaft 16, the tail end of the gear tooth of the ratchet 16 is meshed with the inner teeth of the barrel gear 15, the barrel-shaped pawl 25 is sleeved on the ratchet spring 26, the barrel-shaped pawl 25 is meshed with the outer teeth of the barrel gear 15 below the barrel gear 15, and the ratchet spring 26 is fixed on the inner support 20. Wherein the spring 14, the spring stem 27, the ratchet 16, the mainspring 19 and the barrel gear 15 are coaxial. A barrel gear 15 is externally meshed with a small tooth of a transmission gear 3, a large tooth of the transmission gear 3 is coaxial with the small tooth and has the same rotating speed, a large tooth of the transmission gear 3 is meshed with a small tooth of an escape wheel 4, a large tooth of the escape wheel 4 is coaxial with the small tooth and has the same rotating speed, and a large tooth of the escape wheel 4 is meshed with an upper shifting fork and a lower shifting fork of an escape fork 24; the tail end of the escape fork 24 is connected with an impact pin housing 21 through a pin, the impact pin housing 21 is connected with a rotor 12 of the rotating disc type friction nanometer generator through pins in two circumferential grooves, and the rotor 12 is connected with a balance spring 22 fixed on the rear support 17.

The sea wave trigger device comprises a floating ball 6, a rack sleeve 5, a rack 1, a ratchet 2 and a pawl 14 (namely a tourbillon mechanism clockwork spring). The floating ball 6 is a hollow structure and floats on the sea surface, and the rack sleeve 5 is fixed on the floating ball; a rack 1 is connected above the floating ball 6, and the rack 1 is meshed with the outer teeth of the ratchet 2; the inner teeth of the ratchet wheel 2 are meshed with the pawl 14, and the rotation of the pawl 14 is the process of winding up the spring.
The working principle of the invention is as follows: according to the invention, the sea wave is beaten to drive the sea wave trigger device to work, the sea wave trigger device stores energy through the tourbillon mechanism, the rotating disc type friction nanometer generator is stably and continuously driven to operate, the FEP film 7 on the rotor 12 performs reciprocating rotation motion along with the rotor 12 and generates contact separation motion with the copper electrode film 8 on the stator 13 to generate electric energy, and then the electric energy is used for charging a power supply or supplying power to electrical appliances such as a sensor and the like in real time through an external circuit.
During the working process of the sea wave trigger device, the floating ball 6 is driven by the up-and-down fluctuation of the sea wave to float up and down, so that the rack 1 is driven to move linearly up and down, the rack 1 is meshed with the outer teeth of the ratchet 2, so that the ratchet 2 is driven to rotate, the inner teeth of the ratchet 2 are meshed with the pawl 14, and when the rack 1 moves upwards, the ratchet 2 and the pawl 14 are driven to move clockwise to tighten the clockwork spring. When the rack 1 is down, the ratchet 2 rotates counterclockwise and the pawl 14 does not rotate counterclockwise due to the unidirectional motion of the ratchet-pawl mechanism. I.e. without loosening the spring.
In the operation of the tourbillon mechanism, after the spring 14 is wound, the spring main spring 19 tends to become loose, so that the spring main spring 19 drives the ratchet 16 to rotate counterclockwise. The teeth of the ratchet wheel 16 are engaged with the teeth of the barrel gear 15, thereby rotating the barrel gear 15. The barrel gear 15 is externally engaged with the small teeth of the transmission gear 3 to drive the transmission gear 3 to rotate clockwise, the large gear of the transmission gear 3 is engaged with the small teeth of the escape wheel 4 to finally drive the escape wheel 4 to rotate anticlockwise, but the escape wheel 4 is a mechanical part rotating intermittently, and the motion state of the mechanical part is controlled by the escape fork 24. The oscillation of the pallet fork 24 is controlled by the balance spring 22 and the rotor 12. Balance spring 22 is interconnected with rotor 12, and balance spring 22 acts like a spring to impart a simple harmonic motion to rotor 12, i.e. a reciprocating rotation of rotor 12. The impulse pin housing 21 has a small pin which, during its reciprocating movement, will hit the pallet fork 24 causing it to oscillate, the pallet fork 24 controlling the intermittent rotation of the escape wheel 4 during its oscillation. If an accident occurs, i.e. the barrel pawl 25 and the ratchet spring 26 work when the barrel gear 15 is forced to rotate in the opposite direction, the barrel pawl 25 will be caught in the outer teeth of the barrel gear 15 and prevent the barrel gear from rotating in the opposite direction. Under the constant energy output of spring 14, the system consisting of spring 14, gears (15, 3), escape wheel 4, pallet fork 24, balance spring 22, and armature 12 will continue to operate at a specific frequency (which is determined by the simple harmonic frequencies of balance spring 22 and armature 12).
During the operation process of the friction nanogenerator, the FEP film 7 and the copper electrode film 8 are initially in a contact state, and electrons in the copper electrode film 8 are free electrons. Due to the difference in electronegativity, a part of electrons in the copper electrode film 8 are transferred to the FEP film 7, and a plateau state is achieved. When the FEP film 7 rotates with the rotor 12 and the FEP film 7 comes into contact with the two copper electrode films 8 simultaneously, a part of electrons in the second copper electrode film 8 are transferred to the FEP film 7, the number of electrons transferred from the first copper electrode film 8 to the FEP film 7 is reduced, the electrons are indirectly moved on the two copper electrode films 8, and an induced current is generated. The friction nano-generator completes the power generation work, and the two poles can supply power to each electric appliance through an external circuit (figure 6) of the rectifier diode.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled 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.
