In this embodiment, the voltage output coil of the generator stator 704 is connected to the onboard electrical load through a rectifier circuit and a rechargeable battery.
In the present embodiment, the generator stator 704 is mainly configured as an induction coil, and the generator rotor 705 is configured to include a weight ring having an inner magnetic pole and an outer ring that mainly function to increase rotational inertia.
In this embodiment, the upper end of the belleville return spring 710 is supported in an annular groove in the lower end surface of the internally threaded hollow sleeve 709, and the lower end of the belleville return spring 710 is supported on a flange on the inside of the upper end of the chuck 707.

The working process of the embodiment is as follows:
a typical application of this embodiment is shown in fig. 4, for example, by installing the embodiment in a power cabin at the bottom of the hull of a small-sized ship and connecting the power output end of the embodiment to an electric load. In the process of anchoring or sailing of the ship, the ship body can bump up and down along with the fluctuation of waves, so that the engine base 1 of the invention also bumps up and down along with the ship body, and the whole inertial mass formed by the sliding sleeve 3, the cross arm 5 and the tip cone 6 tends to keep the original position of the whole inertial mass due to inertia. When the ship moves upwards along with waves, the inertia mass body slides downwards along the sliding rod 2 to reduce the distance between the inertia mass body and the base 1, so that the tip cone 6 on the lower side of the cross arm 6 acts on the impact generator 7 on the lower side, the tip cone 6 drives the internal thread hollow sleeve 709 to move downwards through the rubber cap 712 (at the moment, the return spring 710 is compressed), the main shaft 703 is driven to rotate forwards through the coupling of the transmission thread between the tip cone 6 and the outer edge of the head of the main shaft 703, and then the generator rotor 705 is driven to rotate forwards through the one-way bearing 706 (at the moment, the generator rotor is in a locking state) and part of mechanical energy is temporarily stored in the form of rotational inertia energy. When the internal thread hollow sleeve 709 is pressed to the lowest position, the coupling transmission between the internal thread hollow sleeve 709 and the outer edge of the head of the main shaft 703 is stopped, at this time, the main shaft 703 stops rotating, the generator rotor 705 continues to rotate in the forward direction due to inertia without being restricted by the one-way bearing 706 (at this time, the generator rotor is in an unlocking state), then the stator coil of the generator is coupled with the magnetic field generated by the magnetic poles of the rotor to generate a pulsating induced potential, and finally, the rectifying circuit and the energy storage battery of the rectifying and electricity storage module are utilized to convert the mechanical energy contained in the ship bump caused by waves into electric energy with stable voltage and supply power to the ship-mounted electrical.
When the ship moves downwards along with waves, the inertial mass body slides downwards along the sliding rod 2 to increase the distance between the inertial mass body and the base 1, the rubber cap 712 and the return spring 710 both start to return, the extension of the return spring 710 drives the internal thread hollow sleeve 709 to move upwards, and in the process, the coupling of the transmission thread between the inertial mass body and the outer edge of the head of the main shaft 703 drives the main shaft 703 to rotate reversely to enable the one-way bearing 706 to be in an unlocking state, so that the forward rotation of the generator rotor 705 still maintained due to inertia at the moment is not hindered, and the rotational inertia stored in the generator rotor 705 is still converted into electric energy to continuously supply power to the ship-mounted electrical load equipment.
In the above-mentioned up-and-down pitching movement of one cycle, the interaction of the tip cone 6 on the upper side of the cross arm 6 with the impulse generator 7 on the upper side and the electromechanical movement process take place synchronously, but in time-course in anti-phase.
Therefore, the above process is repeatedly and alternately performed between the whole inertial mass and the impact generators 7 on the upper and lower sides along with the up-and-down pitching of the ship, so that the present invention can convert the mechanical energy contained in the pitching of the ship caused by waves into electric energy in the process of anchoring or sailing of the ship and continuously supply power to the onboard electrical load equipment.
It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
