[0040] The application of the technical solution of this utility model has the following technical effects:

[0041] The origami unit utilizes a flexible, foldable material to construct a modular structure, reducing the damage caused by unpredictable waves to the collection device. Multiple origami units can be connected in series as needed, employing a Kreling origami structure with the same structure but opposite folding directions. Several origami units form a serpentine structure, allowing the body to adapt to waves of different frequencies and shapes. Furthermore, the bistable characteristics of Kreling origami are well-suited to the low-frequency and broadband characteristics of wave energy, making it suitable for triboelectric nanogenerators. Its excellent folding characteristics and large fold-to-unfold ratio also allow it to be compressed to a minimum size, which is an advantage for future transportation and deployment. This design enables the serpentine-like power generation device to not only operate normally but also to be compact, lightweight, and inexpensive.

[0042] When waves arrive, the Kreslings origami folds under the force of the waves. The triboelectric effect causes two friction layers with different electrical charges to come into contact vertically. Due to the triboelectric effect, charge transfer occurs between the surfaces of the two friction layers, resulting in the positively charged friction layer acquiring a positive charge and the negatively charged friction layer acquiring a negative charge. When the Kreslings origami unfolds, the two friction layers separate. Due to the accumulation of charge, a potential difference is formed. This potential difference drives the charge to flow in the external circuit, thereby generating current. The periodic contact and separation of the two friction layers can generate continuous electrical energy. The generated electricity is stored in a battery through a circuit. Furthermore, triboelectric nano-power generation technology has high energy harvesting density and is environmentally friendly to low-frequency vibrations. A well-designed origami structure can increase the effective contact area between the two friction layers in the triboelectric nano-power generation device, solving the problem of converting unstable wave energy into stable electrical output.

Detailed Implementation

[0060] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0061] like Figures 1 to 14 As shown, this utility model embodiment provides a bistable origami-inspired serpent wave energy power generation device, including: an anchoring part 1, the anchoring part 1 including a float 11; a device head 2, the device head 2 being connected to the anchoring part 1 via an anchoring line 12; an energy storage part 3, one end of the energy storage part 3 being connected to the device head 2; and a body part 4, one end of the body part 4 being connected to the other end of the energy storage part 3; wherein, the body part 4 is composed of multiple Kresling origami structures connected in series, and the origami structures are provided with triboelectric nano-power generation devices 45.

The device head 2 also includes: a head shell 22, which is a hollow structure; a head end cap 21, which is connected to the head shell 22; a countersunk rivet 23, which is used to connect the head shell 22 and the battery 34 end cap 31; and an O-ring 24, which is placed in the groove at the bottom of the head end cap 21 and is in contact with the head shell 22. The energy storage unit 3 includes: a battery end cap 31, one end of which has an outer side and an inner hole that are both regular octagonal, and the other end of which is round and has threads on the inner side; a battery outer shell 32, which is threadedly connected to the battery end cap 31; a battery inner shell 33, which is threadedly connected to the battery end cap 31; a battery 34, which is placed between the battery outer shell 32 and the battery inner shell 33; and an O-ring 24, which is placed at the contact point between the battery end cap 31 and the battery outer shell 32.

[0063] In this embodiment, the body part 4 includes: a folding unit 41, which includes an outer folding structure 411, an inner folding structure 413, and a folding end face 412; a power generation diaphragm 42, which is placed between the outer folding structure 411 and the inner folding structure 413, separating the outer folding structure 411 and the inner folding structure 413, and the two ends of the power generation diaphragm 42 are connected to the folding end face 412; a waterproof film 43, which wraps around the outside of the outer folding structure 411 and the inside of the inner folding structure 413; a fixing plate 44, which is a regular octagonal thin plate with an inner hole that is half the size of the outer octagon, and the fixing plate 44 is fixedly connected to the folding end face 412 by rivets; and triboelectric nanogenerators 45, which are arranged in parallel. The triboelectric nanogenerator 45 comprises a triboelectric nanogenerator dielectric layer 451, a triboelectric nanogenerator positively charged triboelectric layer 452, and a triboelectric nanogenerator negatively charged triboelectric layer 453, which are arranged in parallel. The triboelectric nanogenerator dielectric layer 451 is tightly bonded to the inner side of the outer folding structure 411 and the outer side of the inner folding structure 413. The triboelectric nanogenerator positively charged triboelectric layer 452 is tightly bonded to the triboelectric nanogenerator dielectric layer 451, and the triboelectric nanogenerator negatively charged triboelectric layer 453 is tightly bonded to the triboelectric nanogenerator dielectric layer 451. The triboelectric nanogenerator positively charged triboelectric layer 452 and the triboelectric nanogenerator negatively charged triboelectric layer 453 are sequentially distributed on the two surfaces of the mountain and valley on the inner side of the outer folding structure 411 and the outer side of the inner folding structure, respectively. An O-ring seal 24 is placed at the contact point between the folding end face 412 and the fixing plate 44. The origami unit 41 includes: an outer origami structure 411, which is folded into a regular octagonal Kresling origami structure, with two Kresling origami structures of the same structure but folded in opposite directions connected in series outside the Kresling origami unit 41 of the outer origami structure 411; an inner origami structure 413, which is folded into a regular octagonal Kresling origami structure, and the size of the inner origami structure 413 is half that of the outer origami structure 411, with four Kresling origami structures of the same structure but folded in opposite directions connected in series inside the Kresling origami unit 41 of one inner origami structure 413; and an origami end face 412, which is connected to one Kresling origami unit 41. Both the outer folding structure 411 and the inner folding structure 413 are made of foldable flexible material. The triboelectric nano-power generation positive triboelectric layer 452 and the triboelectric nano-power generation negative triboelectric layer 453 are made of conductive flexible thin film material, which are respectively positive and negative materials. The triboelectric nano-power generation dielectric layer 451 is made of insulating flexible thin film material.Kresling origami structures are thin-shell cylindrical in shape. These thin-shell cylindrical Kresling origami structures have two stable states, 0 and 1. In the 0 state, they are fully compressed, and in the 1 state, they are fully extended.

[0064] The inner folding structure 413 is filled with water on its inner side and fixed below the seawater surface.

[0065] This embodiment mainly consists of multiple Kresling origami sections connected in series. The bistable characteristics of Kresling origami are well-suited to the low-frequency and broadband characteristics of wave energy. Both ends of the device are sealed, and its interior is filled with water and fixed below the sea surface. Waves crashing against one end of the device compress it, creating an expansion wave that propagates within the origami structure. The wave causing the expansion wave flows at the same speed outside the origami structure, thus exerting greater pressure on the entire device. Under the action of the expansion wave, the origami structure periodically folds and unfolds significantly. The vertical contact-separation mode triboelectric nanogenerator 45, housed inside, generates electricity when its two different friction layers come into contact and electrostatic induction occurs when they separate. Under periodic forces, the two triboelectric layers continuously contact and separate, generating electrical energy. A well-designed origami structure increases the effective contact area of ​​the two different friction layers in the triboelectric nanogenerator 45, effectively solving the problem of converting unstable wave energy into stable electrical output and improving power generation efficiency.

[0066] In this embodiment, as Figure 1-2 The device includes an anchoring part 1, a head 2, an energy storage part 3, and a body 4, which are connected sequentially. The head 2 includes a float 11, an anchoring line 12, and an iron ring 13. The float 11 is an ellipsoidal sphere connected to the anchoring line 12 via a ring at its lower end. The upper end of the anchoring line 12 is connected to the float 11. The float 11 provides buoyancy to the entire device. By artificially changing the depth and angle of the float 11, its natural frequency can be made to match the wave frequency in normal sea conditions and to deviate from the wave frequency in severe sea conditions. This achieves the goal of effectively utilizing wave energy without being destroyed by giant waves. The lower end of the anchoring line 12 is fixed to the seabed, and the middle of the anchoring line 12 is connected to the head 2 via the iron ring 13. The anchoring line 12 limits the range of motion of the entire device to a certain extent, facilitating installation and retrieval of the device and ensuring its stability and safety.

[0067] In this embodiment, as Figure 3The device head 2 includes a head end cap 21, a head outer shell 22, countersunk rivets 23, and O-rings 24. The head end cap 21 is somewhat similar in shape to a semi-circular head screw and is threadedly connected to the head outer shell 22. The head outer shell 22 is a hollow structure with an outer octagonal shape and an inner circular hole. Its rear end is riveted to the battery 34 end cap 31 using countersunk rivets 23. The head end cap 21 and the head outer shell 22 provide a certain structural strength for the device. The O-ring 24 is placed in the groove at the bottom of the head end cap 21 and contacts the head outer shell 22. Two other O-rings 24 of different sizes are placed between the head outer shell 22 and the battery 34 end cap 31, one inside and one outside. The O-rings 24 here prevent seawater from seeping into the head device, ensuring the airtightness of the entire device.

[0068] In this embodiment, as Figure 4 The energy storage unit 3 includes a battery end cap 31, a battery outer shell 32, a battery inner shell 33, a battery 34, and an O-ring 24. One end of the battery end cap 31 has an outer and inner octagonal shape, while the other end is cylindrical with threads on the inner side, allowing it to be threadedly connected to the battery outer shell 32 and the battery inner shell 33. The battery 34 is positioned between the battery outer shell 32 and the battery inner shell 33, and is directly beneath the battery outer shell 31. The battery 34 is limited by the two end faces of the inner shell 33 and the battery 34 end cap 31, the battery 34 outer shell 32, and the battery 34 inner shell 33, which wrap around the outside of the battery 34 and play a crucial role in protecting the battery 34. The O-ring 24 is placed at the contact points between the battery 34 end cap 31 and the battery 34 outer shell 32 and between the battery 34 end cap 31 and the battery 34 inner shell 33. The O-ring 24 here prevents seawater from seeping into the energy storage device and ensures the sealing of the battery 34.

[0069] In this embodiment, as Figure 5-14The body part 4 includes an origami unit 41, a power-generating diaphragm 42, a waterproof membrane 43, a fixing plate 44, a triboelectric nano-power generation device 45, and an O-ring seal 24. The origami unit 41 includes an outer origami structure 411, an origami end face 412, and an inner origami structure 413. The outer origami structure 411 is folded with reference to a regular octagonal Kresling origami structure. Two origami structures with the same structure but opposite folding directions need to be connected in series on the outside of one Kresling origami unit 41. The inner origami structure 413 is also folded with reference to a regular octagonal Kresling origami structure, but its size is half that of the outer origami structure 411. Four origami structures with the same structure but opposite folding directions need to be connected in series on the inside of one Kresling origami unit 41. The origami end face 412 is connected to one Kresling origami unit 41. The thin-shell cylindrical Kresling origami structure has two stable states, 0 and 1. In the 0 state, it is completely compressed. The Kresling origami structure can be fully extended in state 1, and can maintain its own stability in both states 0 and 1 without external force. The two states have a large difference in stiffness. When the Kresling origami structure switches between the two stable states, it can not only achieve length extension and contraction, but also actively undergo a certain degree of torsion. When the origami unit 41 is composed of Kresling origami structures with the same structure and the same folding direction, axial linear motion and circular rotation will be generated at the other end. When the origami unit 41 is composed of Kresling origami structures with the same structure but opposite folding directions, only linear motion (no torsional motion) will be generated at the other end. Therefore, Kresling origami structures with the same structure but opposite folding directions are connected in series. Several origami units 41 are composed of a serpentine structure so that the body part 4 can adapt to waves of different frequencies and shapes. The bistable characteristics of Kresling origami are well targeted at the low-frequency and broadband characteristics of wave energy, which is a triboelectric nanogenerator 45. A well-designed origami structure can increase the effective contact area between the two different friction layers of the triboelectric nanogenerator 45, thereby improving power generation efficiency. The power generation diaphragm 42 is placed between the outer origami structure 411 and the inner origami structure 413, separating them. Its two ends are connected to the origami end faces 412. The power generation diaphragm 42 prevents the triboelectric nanogenerator 45 mounted on the outer origami structure 411 and the inner origami structure 413 from contacting each other under the influence of wave energy, thus preventing the circuitry from burning out. The waterproof... A thin film 43 wraps around the outer side of the outer folding structure 411 and the inner side of the inner folding structure 413. The waterproof film 43 prevents seawater from seeping into the interior and exterior of the outer folding structure 411 and affecting the triboelectric nanogenerator 45 mounted thereon. The fixing plate 44 is a regular octagonal deformed thin plate with an inner hole that is half the size of the outer shape. The fixing plate 44 is fixed to the folding end face 412 by rivets. The fixing plate 44 connects the folding unit 41 and provides a certain strength to the body part 4.To prevent damage to the entire device from severe sea conditions, the O-ring 24 is placed at the contact point between the origami end face 412 and the fixing plate 44. This O-ring 24 prevents seawater from seeping into the body part 4, ensuring the airtightness of the entire device. The triboelectric nanogenerator 45 is attached according to the schematic diagram of the attachment area. The triboelectric nanogenerator 45 consists of a triboelectric dielectric layer 451, a positive triboelectric layer 452, and a negative triboelectric layer 453, arranged in parallel. The triboelectric dielectric layer 451 is tightly attached to the inner side of the outer origami structure 411 and the outer side of the inner origami structure 413. The positive triboelectric layer 452 is tightly attached to the triboelectric dielectric layer 451, and the negative triboelectric layer 453 is tightly attached to the triboelectric dielectric layer 451. The positive triboelectric layer 452 is also tightly attached to the triboelectric dielectric layer 451. Layer 453 is sequentially distributed on the two surfaces of the "mountain / valley" on the inner side of the outer origami structure 411 and the outer side of the inner origami structure. Both ends of the serpent power generation device are sealed. The inner origami structure 413 is filled with water and fixed below the seawater surface. Waves crash against one end of the device, causing it to be compressed and forming an "expansion wave," i.e., an internal pressure wave. The expansion wave propagates inside the inner origami structure 413, while the wave that caused the expansion wave flows at the same speed outside the outer origami structure 411. This creates increasing compression on the body part 4, which is composed of multiple origami units 41 connected in series, causing the expansion wave to grow larger. Under the action of the expansion wave, the body part 4 will swing, and the origami structure will periodically fold and unfold. The vertical contact-separation mode triboelectric nanogenerator 45 installed inside it generates electricity when the two triboelectric layers come into contact and generates electrostatic induction when they separate. Under the periodic force of the waves, the two triboelectric layers continuously contact and separate, thus generating electrical energy. The generated electricity will be stored in the battery 34 through the circuit.

Various modifications and variations can be made to this utility model by those skilled in the art.
