Description

Technical Field

[0001] The present invention relates to the technical fields of floating platforms and friction nano-power generation, and in particular to a floating energy dissipation and vibration suppression device and a self-excited friction nano-power generation platform associated therewith. Background Art

[0002] With the development of ocean energy, offshore floating platforms such as offshore drilling platforms, drilling barges, and floating wind turbines are being vigorously developed. Wave energy is an inexhaustible renewable clean energy source with good energy quality, wide distribution, and large reserves. Harvesting wave energy can power offshore floating platforms, converting the mechanical energy contained in the waves into electrical energy to meet the daily electricity needs of offshore floating platforms. However, existing offshore floating platforms and offshore islands and reefs are often impacted by large waves and ocean current loads during the installation, construction, operation, and daily life. The complex offshore marine environment can cause great damage to the stability of floating platforms. The ports and coastal infrastructure of offshore islands and reefs are constantly impacted by waves. Therefore, the daily electricity consumption of offshore islands and reefs is restricted by the transmission distance and power generation method, and a series of electricity problems such as power outages and voltage instability often occur.

[0003] Floating breakwaters are a better solution for breaking waves, but current floating breakwaters still lack effective protection against ocean currents. Moreover, after existing protection solutions convert wave energy into mechanical energy, they lack a way to further convert and utilize the mechanical energy. This is a huge waste of ocean wave energy and once again exposes the shortcomings of existing technical solutions, which are relatively single in function.

[0004] Currently, there is a lack of a high-performance integrated device that can simultaneously provide a safe construction, operation and living environment for "ocean islands" and a low-cost and stable source of daily electricity, thereby simultaneously solving the harsh environment problems of offshore floating platforms, the safety problems of offshore island and reef foundation structures, and their daily electricity problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a floating energy dissipation and vibration suppression device and a self-excited friction nano-power generation platform combined with it, in response to the current wave and current protection problems and power supply problems in offshore areas. The device can not only reduce the impact of wave and current loads, but also generate sufficient roll to drive the friction nano-power generation device to generate electricity, thereby realizing the conversion of ocean energy from wave energy to mechanical energy and then to electrical energy, and making full use of ocean energy.

[0006] The technical solution adopted by the present invention to solve the above technical problems is:

[0007] A floating energy dissipation and vibration suppression device comprises an upper box-type floating breakwater and a lower energy dissipation and vibration suppression structure. The outer periphery of the energy dissipation and vibration suppression structure is formed of a rigid frame by a high-strength and high-rigidity exoskeleton, and the interior is filled with lightweight, high-strength porous material to form a loose porous structure (the lower energy dissipation and vibration suppression structure as a whole is a rigid outer shell wrapping a loose porous internal structure); the box-type floating breakwater and the high-strength and high-rigidity exoskeleton are fixedly connected by high-strength steel plates, the floating energy dissipation and vibration suppression device is connected to a seabed anchoring structure by a cable, the cable is semi-rigidly connected to a cable clamp, the cable clamp comprises a cable clamp fixing plate, a node plate and high-strength bolts, two cable clamp fixing plates are provided, the two cable clamp fixing plates are fixedly connected to the node plate, and the cable clamp is arranged between the two cable clamp fixing plates and anchored by the high-strength bolts.

[0008] A self-excited friction nano-power generation platform combined with the above-mentioned floating energy dissipation and vibration suppression device includes the above-mentioned floating energy dissipation and vibration suppression device and a friction nano-power generation device arranged inside the box-type floating breakwater. The friction nano-power generation device includes multiple groups of power generation elements, each group of power generation elements is arranged in parallel and rigidly connected to the high-strength and high-rigidity shell of the box-type floating breakwater; at the same time, the wires of each group of power generation elements are connected to external leads, and the external leads extend out of the high-strength and high-rigidity shell. The friction nano-power generation device is coupled through electrostatic induction and friction electrification of the power generation elements, thereby converting mechanical energy in the waves into electrical energy (which is integrated and transmitted to electrical equipment through the external leads).

[0009] According to the above scheme, the power generation element includes a lightweight insulating skeleton of the power generation element, a capacitive nanocomposite material, a rigid connecting central axis, a magnet, a skeleton coil, a conductor, a counterweight, a rectifier bridge, a metal coating, and a silk material. The arc portion of the lightweight insulating skeleton of the power generation element is tightly connected to the high-strength and high-rigidity shell; the capacitive nanocomposite material is tightly bonded to the lightweight insulating skeleton of the power generation element and the counterweight; the conductor is bonded to the capacitive nanocomposite material and, after being connected to the rectifier circuit, is led to an external lead; the counterweight and the portion of the lightweight insulating skeleton of the power generation element bonded with the silk material and wound with the skeleton coil are all connected to the rigid connecting central axis, which is connected to the counterweight and the lightweight insulating skeleton of the power generation element via a bearing; the magnet is bonded to the middle of the inner side of the semicircular portion of the lightweight insulating skeleton of the power generation element (to ensure that the magnetic flux lines can be cut to the maximum extent possible by the coil); and the metal coating is evenly adhered to the outer side of the semicircular portion of the lightweight insulating skeleton of the power generation element (to ensure that the silk material can rub against the metal coating to the maximum extent possible).

[0010] According to the above scheme, the power generation element includes two parts: a friction nano-power generation unit and an electromagnetic induction power generation unit. The movement direction of the power generation element is consistent with the roll direction of the overall structure of the power generation platform (to ensure that the mechanical energy converted from wave energy can be used more efficiently).

[0011] According to the above scheme, the empty part where the box-type floating breakwater and the energy dissipation and vibration suppression structure are rigidly connected is also rigidly connected to the buoyancy adjustable device, which is used to adjust the buoyancy-to-weight ratio and includes at least two sections of buoys with circular cross-sections. The two sections of buoys are arranged at the lower part of the box-type floating breakwater along the entire length of both sides of the energy dissipation and vibration suppression structure.

[0012] According to the above scheme, each section of the buoy is equipped with a gyroscope, a water level monitor, an air inlet pipe and a water supply and drainage pipe. The gyroscope is used to provide accurate level, speed and acceleration signals; the water level monitor is used to monitor the water level signal. The data measured by the gyroscope and the sensor data monitored by the water level monitor are transmitted to the computer. After computer calculation and processing, control instructions are issued to control the water inlet and air outlet of the buoy's air inlet pipe and water supply and drainage pipe (to ensure the balance of the structure).

[0013] According to the above solution, in the upper box-type floating breakwater, the wave-facing area of the high-strength and high-rigidity shell is as large as possible.

[0014] According to the above solution, the height of the lower energy dissipation and vibration suppression structure is designed to be as low as possible.

[0015] According to the above scheme, the self-excited friction nano-power generation platform is constructed as a power generation platform unit, and several power generation platform units are connected by steel cables and the above-mentioned cable clamps to form a power generation platform group. The power generation platform units are distributed at a fixed distance on the strong side of wave load and ocean current load.

[0016] According to the above scheme, for sea areas with high and strong waves and dense ocean currents, multiple power generation platform units are arranged on the side with strong wave loads and ocean current loads; as the wave energy contained in the waves and ocean currents decreases, the distance between the arranged power generation platform units gradually decreases as the distance from the wave loads and ocean current loads increases.

[0017] Compared with the existing floating tunnel anchored floating breakwater power generation method, the present invention has the following beneficial effects:

[0018] 1. The floating energy dissipation and vibration suppression device can simultaneously reduce the motion response of the floating platform under the action of wave and ocean current loads, and reduce the impact of waves on the foundation structures on offshore islands and reefs. Compared with the current mainstream floating breakwaters, it has great advantages in terms of simple structure, low raw material price, easy disassembly and assembly, and good effect in breaking waves and turbulent ocean currents.

[0019] 2. The self-excited triboelectric nanogenerator platform, combined with a novel floating energy dissipation and vibration suppression device, boasts a rational structure and diverse functions. It simultaneously suppresses the vibration of turbulent wave flow and generates electricity by converting mechanical energy from wave energy into electrical energy. Its superstructure possesses excellent wave-breaking capabilities, while its substructure can disrupt turbulent ocean currents, unlike other similar offshore structures. The floating energy dissipation and vibration suppression device not only reduces the impact of wave and current loads, but also drives the rigidly connected self-excited triboelectric nanogenerator device to move through its motion response under the action of ocean wave and current loads, converting the resulting mechanical energy into electrical energy. This enables the conversion of ocean energy from wave energy to mechanical energy and then to electrical energy, thus fully utilizing ocean energy.

[0020] 3. The power generation element of this invention consists of a triboelectric nano-power generation unit and an electromagnetic induction power generation unit. With minimal motion response from the power generation platform, it can generate high power output, resulting in extremely strong power generation capabilities, stable power generation, and high conversion efficiency, enabling a continuous supply of high-quality, clean energy. Furthermore, compared to other existing offshore structures that simultaneously break waves and generate electricity, the overall structure is compact, with the power generation element rigidly connected to the interior of the structure. This avoids the risk of seawater erosion associated with other similar solutions due to the exposed and complex power generation components.

[0021] 4. The introduction of buoys with flexible adjustable buoyancy-to-weight ratio allows the buoyancy-to-weight ratio of the entire structure to be changed arbitrarily within a wide range according to actual conditions, thereby effectively controlling the overall dynamic response of the structure within a reasonable range;

[0022] 5. The power generation platform of the present invention is deployed at the construction site of an offshore floating platform or on the side of an offshore island subject to strong wave and current loads. The superstructure and substructure are fixedly connected by high-strength steel plates, and the cable-to-structure connection interface uses a quick-release connection structure in the form of a cable clamp, which facilitates assembly and disassembly for reuse. The overall structural rigidity is high. At the same time, the power generation elements are embedded in the superstructure, making them less susceptible to damage and corrosion by seawater, making the power generation platform more practical.

[0023] 6. Due to the better wave-breaking ability, new turbulence effect, higher power generation efficiency and better structural design of the present invention, the power generation platform has a wider applicability and stronger functionality. It can be deployed in sea waves and strong ocean currents where similar offshore structures could not be deployed in the past, and can be constructed at sea for a longer time.

DETAILED DESCRIPTION

[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] Reference Figures 1 to 4The floating energy dissipation and vibration suppression device of the present invention comprises an upper box-type floating breakwater and a lower energy dissipation and vibration suppression structure. The outer portion of the box-type floating breakwater adopts a high-strength and high-rigidity shell 17 with a rectangular cross-section. The outer portion of the energy dissipation and vibration suppression structure is formed of a rigid frame by a high-strength and high-rigidity outer skeleton 21, and the interior is filled with a lightweight and high-strength porous material 22 to form a loose porous structure. The high-strength and high-rigidity shell 17 of the box-type floating breakwater and the high-strength and high-rigidity outer skeleton 21 of the energy dissipation and vibration suppression structure are fixedly connected by a high-strength steel plate. Figure 4 As shown; the floating energy dissipation and vibration suppression device is connected to the seabed anchoring structure via a cable 23, the cable 23 is semi-rigidly connected to the cable clamp 24, and the structure and the cable 23 are connected by the cable clamp 24 to achieve force transmission between the two, as shown Figures 10 to 12 As shown, the cable clamp 24 includes a cable clamp fixing plate 241, a node plate 242 and a high-strength bolt 243. Two cable clamp fixing plates 241 are provided, and the two cable clamp fixing plates 241 are fixedly connected to the node plate 242. The cable 23 is clamped between the two cable clamp fixing plates 241 and anchored by the high-strength bolt 243. The cable clamp fixing plate 241 is connected to the cable 23 to provide sufficient friction so that the cable 23 maintains a fixed angle, ensuring the characteristics of semi-rigid constraint.

[0039] The self-excited friction nano-power generation platform combined with the floating energy dissipation and vibration suppression device described in the present invention is arranged at the construction site of the offshore floating platform and on the side with strong wave and ocean current loads of the offshore island. It includes the above-mentioned floating energy dissipation and vibration suppression device and also includes a friction nano-power generation device arranged inside the box-type floating breakwater.

[0040] like Figure 2 As shown, the triboelectric nano-power generation device comprises multiple groups of generating elements 18 and external leads 19. Each group of generating elements 18 is arranged in parallel and rigidly connected to a high-strength, high-rigidity housing 17 (ensuring high voltage and high current while allowing for easy replacement without relative movement). External leads 19 are connected to the wires of each group of generating elements and extend out of the high-strength, high-rigidity housing 17. The generating elements comprise a triboelectric nano-power generation unit and an electromagnetic induction power generation unit. The movement direction of the generating elements 18 aligns with the overall roll direction of the structure, ensuring that the mechanical energy converted from wave energy can be efficiently utilized. The triboelectric nano-power generation device converts the mechanical energy in the waves into electrical energy through the electrostatic induction and triboelectric charging of the generating elements, which are then integrated and transmitted to the power-consuming device via external leads 19.

[0041] The vacant space between the box-type floating breakwater and the energy dissipation and vibration suppression structure is also rigidly connected to an adjustable buoyancy device for adjusting the buoyancy-to-weight ratio. This allows the structure to generate a significant degree of roll and a reasonable frequency under the excitation of wave and current loads, allowing the mechanical energy converted from wave energy to be converted into electrical energy with maximum efficiency, achieving maximum utilization efficiency of the triboelectric nanogenerator. The adjustable buoyancy device includes at least two buoys 20, which are arranged at the bottom of the box-type floating breakwater along the entire length of both sides of the lower energy dissipation and vibration suppression structure. The cross-section of the buoys 20 is circular. Under wave loads, if the area of the elliptical and circular cross-sections is the same, the circular cross-section of the buoys 20 has a larger wave-facing area than the elliptical cross-section, which can increase the dynamic response of the structure.

[0042] The upper box-shaped floating breakwater primarily bears wave loads, serving two purposes: breaking waves and ensuring a sufficiently large wave-facing area to fully convert wave energy into mechanical energy. This energy is then converted into electrical energy by an internal self-excited triboelectric nanogenerator. The lower energy dissipation and vibration suppression structure primarily serves to withstand current loads and disrupt currents.

[0043] like Figure 3 As shown, the lower energy dissipation and vibration suppression structure is constructed around a high-strength, high-rigidity exoframe 21, forming a rigid frame with high rigidity. The interior is filled with a lightweight, high-strength porous material 22, forming a loose, porous structure. The entire lower structure is a rigid shell encasing a loose, porous interior, while the outer rigid frame protects the porous material from being dispersed by ocean currents. The high-strength, high-rigidity exoframe 21 is constructed from composite materials, such as FRP, that are lightweight, have strong material bonding, exhibit excellent corrosion resistance in marine environments, and possess the strength and rigidity required for practical engineering applications. This reduces the overall mass of the rigid frame while ensuring corrosion resistance.

[0044] like Figures 5 to 8As shown, the power generation element 18 of the friction nano power generation device includes a light insulating skeleton 1 of the power generation element, a capacitive nano composite material 2, a rigid connection center shaft 3, a magnet 4, a skeleton coil 5, a wire 6, a counterweight 7, a rectifier circuit (including a rectifier bridge 1 8, a rectifier bridge 2 9, and a rectifier bridge 3 10), a metal coating 11, and a silk material 12. The arc portion of the light insulating skeleton 1 of the power generation element and the high-strength and high-rigidity shell 17 are tightly connected as a whole; the capacitive nano composite material 2 and the light insulating skeleton 1 of the power generation element and the counterweight 7 are tightly bonded to ensure that the capacitive nano composite material 2 reaches the maximum expansion and contraction, thereby producing the best power generation effect; the wire 6 is bonded to the capacitive nano composite material 2, and the wire After being connected to the rectifier circuit, it is led out to the external lead 19, which can transmit the electric energy converted by the friction nano-power generation device to the electrical equipment; the counterweight 7 and the part of the lightweight insulating skeleton 1 of the power generation element bonded with the silk material 12 and the wound skeleton coil 5 are all connected to the rigid connection center axis 3, and the rigid connection center axis 3 is connected to the counterweight 7 and the lightweight insulating skeleton 1 of the power generation element through the bearing; the magnet 4 is bonded to the middle of the inner side of the semicircular part of the lightweight insulating skeleton 1 of the power generation element to ensure that the magnetic flux lines can be cut by the coil to the maximum extent; the metal coating 11 is evenly pasted on the outer side of the semicircular part of the lightweight insulating skeleton 1 of the power generation element to ensure that the silk material 12 can rub against the metal coating 11 to the maximum extent.

[0045] like Figure 9 As shown, each buoy 20 is equipped with a gyroscope 13, a water level monitor 14, an air intake pipe 15, and a water supply and drainage pipe 16. The gyroscope 13 provides accurate level, velocity, and acceleration signals. The water level monitor 14 monitors the water level and its range. When the water level exceeds this range, a computer calculates and controls the buoy 20 to change its buoyancy ratio. The air intake pipe 15 and water supply and drainage pipe 16 control the inflow and outflow of water. Data measured by the gyroscope 13 and the sensor data monitored by the water level monitor 14 are transmitted to the computer, which processes the data and issues control commands to control the buoys 20 with adjustable buoyancy to ensure structural balance. When the structure tilts to the left, the computer issues commands to allow water to enter and air to exit the left buoy 20, while allowing air to enter and air to exit the right buoy (through their respective air intake pipes 15 and water supply and drainage pipes 16), thereby achieving structural balance. When tilting to the right, the operating principle is similar.

[0046] As a preferred embodiment of the present invention, the self-excited triboelectric nano-power generation platform comprises a single power generation platform unit. Several power generation platform units are connected by steel cables to form a power generation platform group. The power generation platform units are spaced apart and located on the side with the strongest wave and current loads. The cable clamps connect the power generation platform units.

[0047] As a preferred embodiment of the above-mentioned preferred solution, in waters with high waves and strong currents, multiple rows of the aforementioned power generation platform units are arranged on the side with the stronger wave and current loads. As the wave energy contained in the waves and currents decreases, the distance between the arranged power generation platform units gradually decreases with increasing distance from the wave and current loads. While achieving the purpose of breaking waves and disrupting turbulent currents, it ensures that the floating triboelectric nano-power generation platform can fully withstand the wave and current loads, thereby converting wave energy into mechanical energy for the floating triboelectric nano-power generation platform with high efficiency.

[0048] As a preferred embodiment of the present invention, the wave-facing area of the superstructure is increased to allow the structure to withstand wave load excitation to a greater extent, ensuring that more wave energy acts on the structure. Figure 1 As shown, the dotted line represents the area that can be enlarged. This preferred solution starts from the amount of wave energy input, so that more wave energy is converted into mechanical energy of the structure, and more mechanical energy will be converted into more electrical energy.

[0049] As a preferred embodiment of the present invention, the height of the substructure is lowered, reducing its anti-roll effect on the overall structure. This preferred solution, inspired by the concept of anti-roll fins, reduces the anti-roll effect of the substructure on the overall structure, allowing wave energy to be more effectively expressed as roll. The triboelectric nanogenerator generates more electricity under greater roll. This preferred solution is suitable for waters with few currents, slow currents, or no currents.

[0050] As a preferred embodiment of the present invention, the wave-facing area of the superstructure is increased, allowing the structure to withstand wave load excitation to a greater extent, allowing more wave energy to act on the structure. At the same time, the height of the substructure is reduced, reducing the substructure's anti-roll effect on the overall structure, allowing more wave energy to manifest as structural roll. This preferred solution combines the advantages of the above two preferred solutions. This preferred solution is suitable for sea areas with small wave loads, few ocean currents, low ocean current velocities, or no ocean currents.

[0051] The present invention is not limited to the applications listed in the specification and implementation methods. For those skilled in the art, various corresponding changes and modifications can be made according to the present invention, and the corresponding changes and modifications all fall within the scope of protection of the claims of the present invention.
