Description

Technical Field

[0001] This invention belongs to the field of marine engineering disaster prevention and mitigation, specifically relating to a wave force sensor and monitoring system based on a triboelectric nanogenerator. Background Art

[0002] With the intensification of global warming and the increasing frequency of extreme marine dynamic disasters, the damage caused by disastrous waves is severe, making the need for safety monitoring of marine engineering structures increasingly urgent. However, existing wave force monitoring sensors have problems. For example, piezoresistive sensors require long-term power supply, and fiber optic sensors are too expensive in terms of manufacturing and installation. In addition, the wired transmission technology currently used in marine engineering is difficult to obtain real-time information on the dynamic response changes of marine engineering structures, and cannot effectively assess their catastrophic processes in a timely manner. Therefore, it is necessary to develop self-powered, low-cost, and easy-to-install wave force sensors and wireless monitoring systems.

[0003] Triboelectric nanogenerators, based on the triboelectric effect and electrostatic induction effect, can effectively convert environmental energy into electrical energy and have attracted much attention in recent years in fields such as energy harvesting and self-powered sensing. Triboelectric nanogenerators generate electrical signals by coupling the triboelectric effect and electrostatic induction effect in four operating modes: vertical contact separation, horizontal sliding, single electrode, and independent layer. A wide range of materials are available for fabrication, and diverse structural designs are possible, meeting the requirements of environmental friendliness, strong environmental adaptability, and low cost. The development of wireless transmission technology also provides technical support for this invention, as long-distance, real-time data transmission is crucial for the dynamic monitoring of marine structures. Lora, as a relatively mature wireless transmission technology, has become an ideal choice for various application scenarios due to its advantages such as long-distance transmission, low power consumption, strong anti-interference, and easy installation.

[0004] This invention aims to develop an underwater wave force sensor and wireless monitoring system based on a triboelectric nanogenerator. It features easy maintenance, convenient installation, environmental friendliness, and low cost. It can transmit key wave data wirelessly over long distances in real time and provide timely early warnings, effectively improving the disaster prevention and mitigation capabilities of marine engineering. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, this invention proposes a wave force sensor and monitoring system based on a triboelectric nanogenerator to achieve long-term dynamic monitoring of wave forces acting on marine engineering structures.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wave force sensor based on a triboelectric nanogenerator, the force sensor comprising:

[0007] The force-electric conversion and fixed support layer consists of a hollow cylinder and a multi-layer hexagonal enclosure structure. The multi-layer hexagonal enclosure structure is arranged in a concentric ring at the bottom center of the hollow cylinder, and a first electrode is set on the wall surface, on which a dielectric layer is set.

[0008] The force-sensing layer consists of a circular disc, a paper-cut structure, and a multi-layered hexagonal enclosure structure. The multi-layered hexagonal enclosure structure is concentrically arranged in a ring in the middle part of the circular disc, and a second electrode is provided on the wall surface. The paper-cut structure is a hexagonal cutout arranged in a concentric ring on the circular disc and on the outside of the multi-layered hexagonal enclosure structure. The circular disc is fixedly connected to the top annular surface of the side wall of the hollow cylinder. Under the action of wave force, the multi-layered hexagonal enclosure structure cooperates with the multi-layered hexagonal enclosure structure to form a sliding triboelectric nanogenerator, realizing the conversion of force to electricity.

[0009] Furthermore, the force sensor also includes a waterproof layer with a concentric annular corrugated structure, which is fixedly connected to the circular piece of the force sensing layer through a hexagonal platform. The waterproof layer not only serves a waterproof function, but it can also undergo greater deformation, has higher sensitivity, effectively senses and transmits changes in external pressure, and does not affect the mechanical properties of the sensing layer.

[0010] Furthermore, the paper-cut structure has axially symmetric and centrally symmetric hexagonal cuts. Starting from the complete hexagon at the center, concentric ring-shaped hexagons are arranged from the inside out. A connecting key of a certain width is set at the midpoint of the hexagonal side of the innermost layer and the first layer outwards, and the remaining parts are hollowed out to form cuts. A connecting key of a certain width is set at the vertex of the hexagonal side of the first layer outwards and the second layer outwards, and the remaining parts are hollowed out to form cuts. A connecting key of a certain width is set at the midpoint of the hexagonal side of the second layer outwards and the third layer outwards, and the remaining parts are hollowed out to form cuts, and so on. The paper-cut structure can buckle in response to the release of internal stress when subjected to external force, and deform in three-dimensional space. It rebounds on its own after the external force disappears.

[0011] Furthermore, both the force sensing layer and the force-to-electric conversion and fixed support layer have multi-layer hexagonal enclosure structures. Each multi-layer hexagonal enclosure structure is arranged in a concentric ring, with enclosures of the same height and number of layers, each layer having a consistent wall thickness and a consistent spacing between layers. When a multi-layer hexagonal enclosure slides into another multi-layer hexagonal enclosure, there is a certain distance between adjacent enclosures, and the wall thickness of each layer of the multi-layer hexagonal enclosure is less than that of each layer of the multi-layer hexagonal enclosure. The multi-layer hexagonal enclosure structure allows relative sliding between the force-to-electric conversion and fixed support layers when the force sensing layer deforms, forming a triboelectric nanogenerator based on the principle of sliding friction, thus realizing the force-to-electric conversion.

[0012] Furthermore, strong magnetic circular micro-magnets are arranged at 60° intervals on the bottom surface of the hollow cylindrical wall of the force-electric conversion and fixed support layer and the outermost wall of the multi-layer hexagonal enclosure structure, with the center as the reference, so that the force sensor can be firmly attached to the surface of the marine engineering structure made of magnetic material.

[0013] Furthermore, the force sensors are distributed in a linear array along the seabed direction while also being distributed in a circular array around the marine engineering structure during application.

[0014] Furthermore, when periodic waves act on the marine engineering structure, the wave force borne by the marine engineering structure changes, and the force sensing layer undergoes a process of tensile deformation and recovery deformation. During this process, the dielectric layer on the force sensing layer and the first electrode on the fixed support layer slide relative to each other, resulting in charge transfer and generating a voltage signal. The magnitude of the force is then inverted based on the force-electric response relationship.

[0015] On the other hand, the present invention also provides a wave force monitoring system based on a triboelectric nanogenerator, which includes a data acquisition module composed of a force sensor array, a data transmission module, and a data processing and early warning module.

[0016] The data acquisition module consists of sensor arrays that are linearly distributed along the bottom of the water and circumferentially distributed along the circumference of the structure, respectively.

[0017] The data transmission module is connected to the data acquisition module via a wired cable, and transmits the acquired voltage signal to the data processing and early warning module on the terminal server.

[0018] The data processing and early warning module processes the data sent by the data transmission module, determines the structural bearing status, and issues an early warning when the preset threshold is triggered multiple times consecutively.

[0019] Furthermore, the data transmission module consists of a wireless transmission chip, a low-power wireless transmission module, a switch, and a power supply device;

[0020] When powered by the power supply device and the switch is turned on, the low-power wireless transmission chip modulates and demodulates the signal through the communication protocol. The voltage signal collected by the data acquisition module is then wirelessly and in real time transmitted to the data processing and early warning module by the low-power wireless transmission module for analysis and timely warning.

[0021] Furthermore, the data processing and early warning module presets a threshold based on the relationship between voltage signal and force, and issues an early warning when the collected signal exceeds a certain threshold and is triggered multiple times.

[0022] The beneficial effects of this invention are as follows: Compared with existing wave force monitoring sensors, this invention utilizes a triboelectric nanogenerator to efficiently convert the periodic wave force experienced by marine engineering structures into electrical signals, achieving self-powered operation without the need for additional batteries or power supplies. The design of the force sensing layer gives it high tensile strength and resistance to large deformations. Combined with the structural design of the force-to-electric conversion and fixed support layers, this ensures accurate and sensitive response of the sensor when subjected to external forces, enabling precise monitoring of wave forces. The use of low-cost silicone rubber and PLA materials reduces costs. Strong magnetic micromagnets are arranged to adhere to ferromagnetic marine engineering structures, making installation simple and convenient. This invention utilizes LoRa wireless communication technology in the data transmission module to achieve long-distance, real-time data transmission, ensuring long-term dynamic monitoring of wave forces on marine engineering structures. The data processing and early warning module can process and analyze the collected data in real time. Once the wave force exceeds a preset safety threshold, an early warning signal will be issued immediately, providing timely feedback and intervention for the safe operation of marine engineering structures. This system, through real-time monitoring and early warning mechanisms, can effectively prevent damage or accidents to marine engineering structures caused by abnormal wave forces, and has important practical application value in the field of marine engineering disaster prevention and mitigation.

[0031] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] like Figure 1 As shown, this invention provides a wave force sensor and monitoring system based on a triboelectric nanogenerator. The sensor is an integrated structure including a waterproof layer 1, a force sensing layer 2, and a force-to-electric conversion and fixing support layer 3. The sensors are linearly arrayed along the seabed and circularly arrayed around a marine engineering structure (such as piles). The sensor array forms a data acquisition module 4. When the engineering structure is subjected to periodic waves, the wave force first acts on the waterproof layer 1. The waterproof layer 1 serves to waterproof and transmit force without affecting the force on the sensing layer 2. After sensing the change in wave force, the force sensing layer 2 undergoes downward deformation and rebound deformation, forming a sliding triboelectric nanogenerator with the lower force-to-electric conversion and fixing support layer 3, generating an electrical signal. The sensor array has built-in magnets and is magnetically fixed to the ferromagnetic material engineering structure. The waterproof layer 1, force sensing layer 2, and force-to-electric conversion and fixing support layer 3 are fixedly connected around their perimeter and sealed with epoxy resin for waterproofing. The sensor array is connected to the data transmission module 5 via a wired cable 7. It transmits the collected voltage signals to the data processing and early warning module 6 using LoRa wireless communication. The data processing and early warning module 6, located on a server terminal, processes and visualizes the voltage signals sent by the data transmission module 5 in real time. When the wave force value analyzed by the data processing and early warning module 6 continuously triggers a preset safety threshold multiple times, an early warning mechanism is automatically triggered, alerting operators to take appropriate safety measures via audible and visual signals or remote notification. The system continuously monitors wave force changes in marine engineering structures and periodically updates the data to ensure its continuity and accuracy. A user interface is provided, allowing operators to view historical data, real-time data, and early warning records, as well as configure and adjust system parameters.

[0033] Figure 2 The structure of the waterproof layer 1 is shown. It is made of silicone rubber with a Shore hardness of 30 and is manufactured using a molding process. It is designed as a circular diaphragm with concentric annular corrugations 101. The six hexagonal protrusions 102 on all four sides are fixedly connected to the force sensing layer 2. The function of the waterproof layer 1 is to prevent water from entering the sensor, transmit wave force, and not affect the force on the force sensing layer 2.

[0034] Figure 3 The structure of force-sensing layer 2 is shown. It is made of silicone rubber with a Shore hardness of 70 and manufactured using a molding process. The upper part is a circular sheet 201 of a certain thickness, with hexagonal cutouts around its perimeter, forming a paper-cut structure 202 for force-sensing layer 2, thereby improving its strain sensitivity and deformation resistance. A multi-layered hexagonal wall structure 203 is connected to the upper center, with copper foil attached to the wall surface as electrodes 204 and PTFE as the dielectric layer 205.

[0035] The paper-cutting structure 202 has axially symmetric and centrally symmetric hexagonal cuts. Starting from the complete hexagon at the center, concentric ring-shaped hexagons are arranged from the inside out. A connecting key of a certain width is set at the midpoint of the hexagonal side of the innermost layer and the first layer outside, and the remaining parts are hollowed out to form cuts. A connecting key of a certain width is set at the vertex of the hexagonal side of the first layer outside and the second layer outside, and the remaining parts are hollowed out to form cuts. A connecting key of a certain width is set at the midpoint of the hexagonal side of the second layer outside and the third layer outside, and the remaining parts are hollowed out to form cuts, and so on. By introducing cuts into the elastic material, the material properties are optimized, especially to improve the shortcomings of traditional elastic thin plates, such as small longitudinal deformation and easy fatigue. By introducing an axisymmetric and centrally symmetric paper-cutting structure, this structure possesses excellent deformation capabilities. When subjected to external forces, it can buckle due to the release of internal stress, resulting in significant deformation in three-dimensional space. After the external force disappears, it rebounds on its own. Therefore, this sensor has the ability to deform in response to changes in wave force, self-recover, and resist large deformations caused by loads.

[0036] Both the force-sensing layer 2 and the force-electric conversion and fixed support layer 3 have multi-layer hexagonal enclosure structures. For a single multi-layer hexagonal enclosure structure, its characteristics are a concentric ring arrangement with enclosures of the same height and number of layers, each layer having a consistent wall thickness and consistent spacing. However, comparing the multi-layer hexagonal enclosure structure 203 of the force-sensing layer 2 and the multi-layer hexagonal enclosure structure 302 of the force-electric conversion and fixed support layer 3, in order for the force-sensing layer 2 to slide continuously and smoothly into and out of the force-electric conversion and fixed support layer 3 when subjected to external forces and undergoing longitudinal deformation, there should be a certain distance between adjacent enclosures when the multi-layer hexagonal enclosure 203 slides into the multi-layer hexagonal enclosure 302. Furthermore, the wall thickness of each layer in the multi-layer hexagonal enclosure 302 should be less than the wall thickness of each layer in the multi-layer hexagonal enclosure 203. Apart from this, the height and number of layers are identical for both. It is precisely because of its multi-layered hexagonal enclosure structure that the force-to-electric conversion layer 2 is allowed to slide relative to the fixed support layer 3 when it deforms, thus forming a triboelectric nanogenerator based on the principle of sliding friction, thereby realizing the force-to-electric conversion.

[0037] Figure 4 The diagram shows the structure of the force-to-electric conversion and fixed support layer 3, made of PLA material. The structure is a hollow cylinder 301 with an open top. At the bottom center of the hollow cylinder is a multi-layered hexagonal enclosure structure 302, with the same number of layers as the multi-layered hexagonal enclosure structure 203 of the force-sensing layer. Each enclosure layer is slightly narrower, allowing the force-sensing layer 2 to slide in and separate during downward pressure and rebound deformation. Copper foil is attached to the wall surface of the enclosure structure 302 as electrodes 303. In the first stage, the force-sensing layer 2 and the force-to-electric conversion and fixed support layer 3 are completely separated. Due to the difference in electronegativity, the electrodes 204 and dielectric layer 205 of the force-sensing layer 2 generate equal and opposite charges on their surfaces. Because PTFE has a higher electronegativity than copper foil, the surface of dielectric layer 205 carries a negative charge, while the surface of electrode 204 carries a positive charge. In the second stage, when the force-sensing layer 2 senses the wave action, it presses down, and the multi-layer hexagonal enclosure structure 203 slides into the multi-layer hexagonal enclosure structure 302 of the force-to-electric conversion and fixed support layer 3. During the relative sliding process, as free electrons in the external circuit flow from electrode 303 to electrode 204, positive charges are generated on the surface of electrode 303 to balance the potential difference. In the third stage, when the dielectric layer 205 is in complete contact with electrode 303, the charge is completely transferred. In the fourth stage, the force-sensing layer 2 rebounds, and the multi-layer hexagonal enclosure structure 203 and the multi-layer hexagonal enclosure structure 302 of the force-to-electric conversion and fixed support layer 3 slowly separate. The charge begins a round of reverse transfer, generating an opposite output signal. Therefore, as the force-sensing layer 2 periodically slides into the structure of the force-to-electric conversion and fixed support layer 3 under the periodic wave action, the sensor outputs a periodic alternating voltage signal. The bottom of the hollow cylinder 301 with an open top is equipped with a strong magnetic circular micro magnet 304 arranged at 60° intervals around the center to achieve adsorption and fixation of the sensor to the marine engineering structure, which facilitates installation.

[0038] Figure 5 The diagram shows the internal structure of the data transmission module 5, which basically includes a circuit board 501, a wireless transmission chip 502, a low-power wireless transmission module 503, a switch 504, a sensor multi-channel interface 505, and a power supply device 506. The sensor is connected to the sensor multi-channel interface 505 via a wired cable 7. Turning on the switch 504 activates the power supply device 506, which then powers the low-power circuitry. Data collected by the sensor is modulated and demodulated using the LoRa communication protocol at the wireless transmission chip 502, and then wirelessly and in real-time transmitted to the data processing and early warning module 6 by the low-power wireless transmission module 503. The circuit board 501 integrates various electronic components and integrated circuits.

[0039] Figure 6 The figure shows the force-displacement curves of the force sensing layer 2 in the physical object of this patent during static loading and unloading. The thickness of this object is 5mm, but the maximum deformation can reach 25mm, which shows that the force sensing layer 2 can resist large deformation with a deformation rate of 500%, and can return to the initial state after unloading. Figure 7 The image shows the voltage signals generated by the actual product of this patent when it is working in air and water, demonstrating that the structural design has the ability to work stably in air and water.
