Description
Technical Field
The invention discloses a device for efficiently utilizing ocean wave energy and ocean photovoltaic energy, and belongs to the technical field of power generation devices.
Background
Currently, researchers have invented various TENGs in order to collect various forms of energy, but TENGs are mainly classified into the following four types according to the positions of electrodes and the movement forms of friction layers: vertical contact-separation, horizontal sliding, single electrode, independent layer.
The working mode of the TENG is vertical contact-separation type, in the initial state, the two electrodes are electrically neutral, the electrodes are mutually contacted under the action of external force, the attraction capability of the two electrode materials to electrons is different, and electrons are transferred between the two electrodes, so that a certain voltage is generated between the upper friction layer and the lower friction layer, and the transfer of mechanical energy to electric energy is realized. The horizontal friction positive principle is the same as the vertical contact-separation TENG except that the relative motion pattern of the two electrodes changes from perpendicular to the friction layer to parallel to the friction layer. The independent layer is the extension of the above-mentioned TENGs, the friction layer carries certain electric charge after friction with two electrodes, it will produce periodic alternating current between two electrodes when the relative movement between two electrodes.
TENG has significant advantages over conventional electromagnetic generators in collecting low frequency, low amplitude, irregularly moving energy, and therefore its use in ocean wave energy collection and power generation is of great academic interest.
The existing TENG power generation technology has the following defects:
first, in the conventional TENG power generation technology, the contact tightness between the electrode and the friction surface has an important influence on the power generation performance. The transfer of electric charge is generated by friction, and the friction also generates heat, namely the conversion from mechanical energy to thermal energy, so that the matching precision of the friction layer and the electrode is particularly important. However, since the friction layer is usually thin and the base is usually hard material, the existing TENG generator often has the problem that the electrode is not in close contact with the friction material or the contact friction is too large, which limits the power generation efficiency of the generator.
Secondly, the existing wave energy power generation TENG adopts a friction and contact-separation mode of an inner ball and an outer wall to generate power, the power generation area in unit volume is small, the space utilization rate is low, the friction degree is low, and the power generation efficiency is very limited.
In practical applications where TENG captures mechanical energy in the surrounding environment, the electrical output performance of TENG is an important issue we focus on, and its surface charge density is the most important parameter in determining TENG output performance. In addition, heat generated by sliding friction in the medium-high frequency region and huge abrasion of the material surface seriously degrade the electrical output performance of TENG. The existing wave energy power generation TENG mainly collects the energy of the vertical motion caused by waves, the collecting capacity of the wave horizontal motion energy is poor, the wave energy cannot be fully absorbed, and the energy conversion efficiency is low.
Finally, the conventional TENG ocean wave energy power generation equipment is complex in general process flow, and the nano-scale surface treatment is carried out on the material by adopting laboratory precision equipment, so that the cost is quite high.

In the embodiment, the waterproof glue coating is uniformly coated at the gap between two components at the position where sealing is needed in the running process, so that the whole device is tightly packaged, and the device can work in a marine environment.
The specific working process is as follows:
the central shaft 400 is fixed on a certain wave-carried floating object 500 in the ocean, such as a ship, the rotational freedom of the central shaft 400 is limited, the freedom of movement in the vertical direction is not limited, when one wave is acted on the impeller 305, the wave energy is decomposed into the vertical direction and the horizontal direction, the vertical wave energy drives the whole device to move in the vertical direction, if the device is subjected to the downward movement of the wave energy, the vertical vibrator 216 moves downwards due to inertia, the spring 208 below the vertical vibrator 216 is compressed, the second FEP dielectric film 218 on the surface of the vertical vibrator 216 can perform friction with the PTFE film 219 on the inner surface of the stator 205, and the friction electrification effect occurs between the two friction layers, so that equal negative charges are respectively generated on the FEP surface and positive charges are generated on the Cu surface. In the initial state, positive and negative charges are induced on the electrode 1 and the electrode 2, respectively, due to electrostatic induction to shield unbalanced electrostatic fields. During the downward movement of the vertical vibrator 216 until the end state, a potential difference is generated between the two electrodes to drive the transfer of negative charge from electrode 1 to electrode 2, thereby maintaining the static steady state. Due to the symmetrical structure of the interdigital electrodes, a reverse potential difference is induced to generate a reverse current output in the process of moving from the end state to the next start state.
If the device is rotated clockwise by the energy of the wave, the rabbit hair 204 on the inner surface of the rotor 203 is now able to rub against the first FEP dielectric film 207 on the outer surface of the stator 205, where the triboelectric effect occurs between the two friction layers, thereby creating an equal amount of negative charge on the FEP surface and positive charge on the Cu surface, respectively. In the initial state, positive and negative charges are induced on the electrode 1 and the electrode 2, respectively, due to electrostatic induction to shield unbalanced electrostatic fields. During the clockwise rotation of the rotor 203 until the end state, a potential difference is generated between the two electrodes to drive the transfer of negative charge from electrode 1 to electrode 2, thereby maintaining a stable state of static electricity. Due to the symmetrical structure of the interdigital electrodes, a reverse potential difference is induced to generate a reverse current output in the process of moving from the end state to the next start state. At the same time, the gear ring 111 rotates clockwise together with the magnet power generation housing 101, after the sun gear 106 is accelerated, the magnets 109 and the coils 110 in the circumferential array rotate relatively rapidly, and in the process that the magnets 109 rotate from the starting state to the ending state, the magnetic flux in the copper coils 110 is gradually reduced, and corresponding current is generated in the coils 110 due to Lenz's law so as to generate a magnetic field which prevents the magnetic flux from reducing. Similarly, when the array of magnets 109 is rotated from an end state to the next start state, a corresponding reverse current is generated.
For all the generated currents, the currents generated by the energy storage electrodes of the friction vibration power generation assembly 200 and the electromagnetic power generation assembly 100 are led out along the inner hole of the central shaft 400 through wires, the led wires are fixed on the central shaft 400, and in this embodiment, a coil transformer is used to adjust the output impedance of the friction vibration power generation assembly 200 and the electromagnetic power generation assembly 100. After the adjustment of the transformer, the output impedances of the friction vibration power generation assembly 200 and the electromagnetic power generation assembly 100 are respectively adjusted to values of which the open circuit voltage values are both about 5V. Meanwhile, the short-circuit currents of the friction vibration power generation assembly 200 and the electromagnetic power generation assembly 100 also change accordingly. In practical applications and electrical energy storage, rectifying circuits are often required to convert the AC signal of the overall device to a DC signal. After the transformer is used, the rectified short-circuit current of the whole device is the superposition of the effective output of the friction vibration power generation assembly 200 and the electromagnetic power generation assembly 100, and the voltage output value is basically stabilized at 5V after parallel superposition. The outputs of the friction vibration power generation assembly 200 and the electromagnetic power generation assembly 100 can be hybridized by the above method and achieve the effect of 1+1> 2.
