Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] The present invention discloses a tumbler-type nano power generation device utilizing wave and tidal energy, comprising a power generation box, an energy storage device, a housing 1, a water storage device and a rectifier;

[0045] The generator box includes an upper box 4, a middle box 5 and a lower box 6. The upper box 4 and the lower box 6 are fixed to the plate surface of the housing 1 by screws, and the middle box 5 is embedded in the middle of the box body by a spherical structure.

[0046] There are multiple dark compartments, and a dielectric layer and copper foil electrodes are installed on the inner wall of the dark compartments;

[0047] The upper box 4, the middle box 5 and the lower box 6 are all composed of a shell 1, a box cover 9 and a nano friction material, and are connected together by self-tapping screws to form a relatively closed space;

[0048] The nano friction material uses 80μm thick FEP film as the dielectric layer, a conductive cloth tape as the lower electrode, and a 75μm thick thin copper foil as the upper electrode;

[0049] Energy storage devices and rectifiers are installed on both sides of the upper box 4 and the lower box 6 respectively;

[0050] A water storage device is provided on the upper part of the power generation box, and a drip plate 10 is provided at the bottom of the water storage device;

[0051] The drip plate 10 is provided with circular holes arranged in a triangular prism arrangement, and the arrangement is such that the top edges of the triangular prisms in the first row are located just above the top edges of the triangular prisms in the second row;

[0052] The two sides of the triangular prism are designed with 75° bevels;

[0053] An energy collecting rotating device is arranged above the water storage device, and a rotating blade 2, a rotating shaft 3, a heavy ball 7 and a light ball 8 are arranged in the energy collecting rotating device;

[0054] A plurality of heavy balls 7 and light balls 8 are provided, and the heavy balls 7 and light balls 8 are placed opposite to each other in the energy collecting rotating device;

[0055] A hidden compartment is also provided on the side of the power generation box, and a plurality of hidden compartments are provided, and a hidden compartment plate 11 is provided in the hidden compartment;

[0056] A water droplet power generation film is attached to the inner panel of the shell 1. The water droplet power generation film adds two layers of films made of polymer materials to the conventional solar cell, one layer is polydimethylsiloxane PDMS, and the other layer is polymer PEDOT:PSS;

[0057] A bridge circuit is used for rectification, and a chopper circuit is used for voltage stabilization and voltage reduction.

[0058] The chopper circuit includes an inductor, a capacitor C2 and a freewheeling diode.

[0059] Basic principles of the present invention:

[0060] When materials come into contact, friction is generated. Different materials have different abilities to bind electrons, which results in charge transfer. The two materials present different electrical properties. This is the triboelectric effect. The device of the present invention converts waves into electrical energy based on this effect.

[0061] When two friction material thin layers with different friction polarity come into contact and rub, the charge is transferred. When they separate, they carry opposite charges and form a potential difference. The electrodes pasted on the back of the two materials are connected through a load. The potential difference will cause electrons to flow between the two electrodes to balance the electrostatic potential difference between the friction thin layers. When they come into contact again, the potential difference between the friction thin layers disappears, and the electrons flow in the opposite direction. The friction thin layers are constantly in contact and separated, outputting alternating current pulse signals.

[0062] The power generation principle of the present invention:

[0063] The power generation method designed by the present invention has two working modes. On the one hand, the lightweight ball rolls back and forth and rubs against the PTEF to generate electrical energy, such as Figure 5 shown.

[0064] On the other hand, the friction between water droplets and PETF generates electricity, which can be divided into the electrification process and the power generation process. Figure 6 As shown, the water droplets and PTEF have different electrical polarities. Their mutual friction causes the dielectric layer and the water droplets to have different charges and generate electrical energy at the same time. This is the electrification process.

[0065] like Figure 7 As shown, when the surface of the friction thin layer is full of charges, its surface charge density is the largest, and the transfer of electrons comes entirely from electrostatic induction, resulting in nano-electricity generation by friction of water droplets.

[0066] The present invention utilizes the structure of a tumbler to combine a water drop friction nanogenerator with a small ball friction nanogenerator, which can more efficiently convert wave energy into electrical energy.

[0067] When the tumbler is shaken, the heavy ball 7 rolls along the arc of the inner wall, and this movement will drive the rotor 2 to rotate around the shaft 3. Since the center of gravity of the tumbler is located on the central axis, close to the bottom, the movement of the heavy ball 7 will increase the torque on the tumbler device, thereby extending the shaking time, which helps to improve the power generation efficiency of the balls inside the device.

[0068] Moreover, the impact force of water inside the tumbler has an important influence on the power generation efficiency. When the tumbler swings, the swing amplitude increases, causing the water inside the box to produce a strong impact force, which can further increase the power generation efficiency of the device.

[0069] At the bottom of the tumbler power generation device, a certain space is reserved for placing heavy objects. By placing heavy objects at the bottom, the stability and swinging inertia of the device can be increased. The presence of heavy objects makes the center of gravity of the device lower, thereby increasing the stability of the device and reducing the interference of external factors on the movement of the device.

[0070] When the device swings, the change in position of the weight will generate kinetic energy, and the swinging pattern of the tumbler can convert this part of the kinetic energy into electrical energy.

[0071] In addition, a secret compartment is provided on the side of the power generation box for placing small balls for friction power generation. Through the principle of friction power generation, the friction between the small balls and the secret compartment generates electrical energy.

[0072] The present invention designs 75° inclined surfaces on both sides of the triangular prism, which can make the water droplets drip faster and more stably, and will not stay on the inclined surface during the dripping process, thereby ensuring the smooth dripping of the water droplets and further improving the power generation efficiency.

[0073] The present invention uses 80 μm thick FEP film as the friction power generation material, and uses 75 μm thick thin copper foil as the electrode material. The reason for using FEP film as the dielectric layer is that it has good insulation performance and high heat resistance, can effectively isolate charges and maintain a stable electric field distribution, and the flexibility of the FEP film and the interfacial bonding ability with the metal help to enhance the bonding strength and stability between the dielectric layer and the electrode. The conductive cloth tape (CCT) is selected as the lower electrode because it has good electrical conductivity and mechanical strength, and can effectively collect and derive the generated charges. The thin copper foil is selected as the upper electrode because it has good electrical conductivity and can provide a low-resistance current path.

[0074] Among them, the role of energy storage transposition is to convert the mechanical energy generated by the swing of the tumbler into electrical energy and store it. The rectifier is used to convert the stored electrical energy into direct current and output it; in this way, the upper and lower boxes not only have the function of generating electricity, but also can effectively store and output electrical energy. The present invention uses a bridge circuit to rectify the output of the friction nanogenerator. The bridge circuit can convert alternating current into direct current, and unify the direction of the current through the rectification operation to make it a unidirectional direct current. After rectification, it is subjected to voltage stabilization and voltage reduction processing by the step-down chopper circuit. The step-down chopper circuit can reduce the high voltage output by the friction nanogenerator and adjust it to a working voltage range suitable for the energy storage unit and electrical components. At the same time, the voltage stabilization circuit can maintain the stability of the output voltage to ensure the reliable operation of the energy storage system. The energy storage system can convert the alternating current output by the friction nanogenerator into direct current, and perform voltage stabilization and voltage reduction processing on it to meet the working requirements of the energy storage unit and electrical components.

[0075] The working principle of the raindrop power generation film attached to the inner surface of the shell 1 of the present invention is that PDMS can generate triboelectric effect with falling raindrops, and the PEDOT:PSS film layer serves as the electrode of the triboelectric nanogenerator and can transmit electrical energy to the solar cell. At the same time, both films are transparent, so they will not affect the power generation capacity of the solar cell itself. Compared with other technologies using similar principles, this technology has the advantages of light and thin material, simple design, and easy manufacturing.

[0076] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
