[0029] like Figure 1-5 As shown, an embodiment of the present application provides a multi-dimensional wireless monitoring device for an offshore floating wind turbine, which mainly includes a housing 1, a double-helix monitoring sensor 3, and a data monitoring system 4. The housing 1 is fixedly mounted on an offshore floating wind turbine platform 2, and includes a closed wall surface and an installation cavity 11 formed by the wall surface. The double-helix monitoring sensor 3 is located within the installation cavity 11, and one end of the double-helix monitoring sensor 3 along the axial direction is fixed to the wall surface of the housing 1. The double-helix monitoring sensor 3 is a multi-layer double-helix structure 31, and the double-helix structures 31 of adjacent layers can separate and contact each other. The double-helix structure 31 includes a conductive layer 311 and a dielectric layer 312 arranged along the thickness direction. The data monitoring system 4 is located within the installation cavity 11, and the signal input end of the data monitoring system 4 is electrically connected to the double-helix monitoring sensor 3, and the signal output end of the data monitoring system 4 is connected to the server data.

[0030] The multi-dimensional wireless monitoring device for offshore floating wind turbines in this embodiment includes a double-helix monitoring sensor 3, a data monitoring system 4 and a shell 1. The double-helix monitoring sensor 3 uses the TENG contact-separation electrification principle to convert the kinetic potential energy of the offshore floating wind turbine platform 2 into a continuous electrical signal. The data monitoring system 4 processes and stores the collected voltage signals in real time and transmits the collected signals to a remote end for visual analysis of the monitoring results. When the voltage signal is higher than the set voltage threshold, an early warning is issued. The entire monitoring device has high monitoring sensitivity and low cost, and can perform more accurate monitoring of marine engineering structures.

[0031] like Figure 1-2As shown, in a specific embodiment, the material of the conductive layer 311 is carbon black polylactic acid, and the material of the dielectric layer 312 is thermoplastic polyurethane elastomer. In the present embodiment, each layer of the double helix monitoring sensor 3 is composed of carbon black polylactic acid (PLA-CB) and thermoplastic polyurethane elastomer (TPU), which serve as the conductive layer 311 and the dielectric layer 312 respectively. The double helix structure 31 of the multi-layer structure is based on the friction nano-power generation technology. The multi-layer structure increases the contact area between the layers to reduce the pitch, amplifies the structural deformation, and thus can better amplify the electrical signal. In addition, the double helix monitoring sensor 3 can be formed by 3D printing. The materials of the dual nozzles of the 3D printer are carbon black polylactic acid (PLA-CB) and thermoplastic polyurethane elastomer (TPU), and are printed in an integrated manner at the same time. Due to the 3D printing technology, the structure can be printed out effectively, conveniently and quickly, and the cost is also lower.

[0032] In the above embodiment, the double-helix monitoring sensor 3 is based on friction nano-power generation technology and is designed as a multi-layer double-helix structure 31. It can more accurately monitor the tiny deformation and vibration of the offshore floating wind turbine platform 2, and convert it into electric current and transmit it to the data monitoring system 4. The data monitoring system 4 can perform data processing and analysis in real time and send the monitoring data to the server. The data monitoring system 4 has a preset voltage threshold during operation. When it is determined that the offshore floating wind turbine platform 2 shakes beyond the threshold, further measures are taken to ensure the safety of the offshore floating wind turbine structure.

[0033] like Figure 4-5 As shown, in a specific embodiment, when the offshore floating wind turbine platform 2 is displaced and / or vibrates, the adjacent double helix structures 31 of the double helix monitoring sensor 3 separate and contact multiple times, charge transfer occurs to generate electrical signals, and the data monitoring system 4 receives the generated electrical signals and performs analysis, early warning and wireless data transmission.

[0034] Wireless sensing technology encompasses data acquisition, wireless transmission, data processing, and early warning technologies. Wireless transmission requires no wiring, making deployment more flexible and significantly reducing overall costs. As an emerging wireless transmission method, narrowband IoT offers significant advantages in power consumption, bandwidth, and distance, and has become a research hotspot in the wireless transmission field.

[0035] Specifically, the multi-dimensional wireless monitoring device for offshore floating wind turbines can be placed horizontally on the offshore floating wind turbine platform 2. When impacted by waves or when the wind turbine is displaced, contact-separation occurs between adjacent layers of the double helix structure 31 based on the TENG contact-separation electrification principle, thereby generating an electrical signal. Taking the figure as an example, when the double helix structure 31 of the double helix monitoring sensor 3 moves to the left, since its right end is fixed, it will produce contact due to inertia. When the double helix structure 31 moves to the right end, it will produce separation. This cycle repeats, causing it to continuously produce contact and separation, charge transfer occurs, and current is generated. Moreover, it is an active sensor that does not require external power supply, converting the kinetic potential energy of the offshore floating wind turbine into electrical energy, thereby continuously generating electrical signals.

[0036] like Figure 1 As shown, in a specific embodiment, any two double helix structures 31 of adjacent layers are electrically connected to the data monitoring system 4 through wires; a guide tube 12 is provided on the wall of the shell 1, and the length direction of the guide tube 12 extends along the axial direction of the double helix monitoring sensor 3 and is sleeved in the cavity of the double helix monitoring sensor 3, and the side wall of the guide tube 12 is provided with a through hole for the wire to pass through.

[0037] Specifically, the shell 1 is a hollow cylindrical structure. A guide tube 12 with a hollow tubular structure is connected to the center of one end face of the shell 1. The diameter of the guide tube 12 is smaller than the inner diameter of the double-helix monitoring sensor 3, and the length is smaller than the axial length of the shell 1. A small circular hole (through hole) is opened on the side of the guide tube 12 to facilitate the passage of the wire. Fixing the double-helix monitoring sensor 3 and the data monitoring system 4 on the inner side of the end wall of the shell 1 can effectively improve the space utilization rate. One end of the two wires is respectively connected to the two adjacent layers of the double-helix monitoring sensor 3, and then the two wires pass through the through hole from the guide tube 12 and are connected to the data monitoring system 4.

[0038] like Figure 1 As shown, in a specific embodiment, the shell 1 is an acrylic tube shell, and a waterproof cover 13 with a sealing strip is provided at one end of the shell 1. The waterproof cover 13 can open and close the installation cavity 11. The waterproof cover 13 with the sealing strip can effectively ensure the waterproof performance of the acrylic tube shell.

[0039] like Figure 3 As shown, in one specific embodiment, data monitoring system 4 includes a data acquisition chip 41 and a signal processing and warning module 42. Data acquisition chip 41 is used to collect signals, while signal processing and warning module 42 is capable of receiving collected data in real time and issuing warnings and data transmission. Specifically, data acquisition chip 41 transmits the voltage signals collected by data acquisition chip 41 wirelessly and in real time to signal processing and warning module 42 for analysis and warning via narrowband Internet of Things wireless communication.

[0040] like Figure 4-5 As shown, the signal processing and early warning module 42 receives the collected signal from the data acquisition chip 41 in real time. The size of the collected signal is positively correlated with the vibration of the offshore floating wind turbine platform 2. When the collected voltage signal exceeds the early warning voltage threshold, it can be determined that the offshore floating wind turbine is in a dangerous state, and certain measures can be taken to ensure the structural safety of the offshore floating wind turbine.

[0041] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
