Description

Technical Field

[0001] This invention belongs to the field of power generation technology, and in particular relates to a distributed water power supply device based on friction-permanent magnet composite power generation. Background Technology

[0002] The development and utilization of distributed clean energy has become an important way to solve energy shortages and environmental pollution problems in remote areas, islands, and oceans. For example, the application of distributed energy systems in remote areas can reduce reliance on expensive diesel generators, lower energy costs, and utilize renewable energy sources such as wind and solar power as power generation sources, eliminating fuel transportation costs and generating no pollution, thus offering good environmental and economic benefits. Furthermore, distributed energy systems can achieve local power supply, reduce power transmission losses, improve power supply efficiency, and lower transmission costs, thereby improving the reliability of energy supply in remote areas.

[0003] Currently, while traditional renewable energy technologies such as solar, wind, and hydropower have been widely applied, they still have significant inherent limitations. Solar power generation is highly dependent on sunlight conditions and is greatly affected by day-night cycles and weather changes, making it difficult to achieve stable output around the clock. Wind power generation has a high start-up threshold requirement for wind speed; its power generation capacity decreases significantly or even ceases to operate in low wind speed or calm wind environments. Traditional electromagnetic generators (EMGs) have poor response capabilities to low-frequency, random, and irregular mechanical energy, resulting in low energy conversion efficiency. They are also unable to effectively capture and utilize the weak mechanical vibration energy or wave energy commonly found in the environment, leading to low overall energy harvesting and utilization rates. Summary of the Invention

[0004] In view of this, the present invention aims to provide a floating distributed energy supply device based on friction-permanent magnet composite power generation, which significantly improves the environmental adaptability and power supply reliability of the distributed energy supply system through the composite power generation structure.

[0005] To achieve the above objectives, the technical solution created by this invention is implemented as follows: This invention provides a floating distributed energy supply device based on friction-permanent magnet composite power generation, comprising: a wind power generation unit and a hydropower generation unit. The wind power generation unit includes: multiple wind cups, an upper drive shaft, internal electrodes, an electrode mounting frame, a magnet mounting frame, and multiple magnets. The hydropower generation unit includes: multiple conical cups, a lower drive shaft, an annular cover, external electrodes, and multiple power generation coils. Multiple wind cups are radially connected to the upper drive shaft, and the wind cups drive the upper drive shaft to rotate via wind power. An electrode mounting frame and a magnet mounting frame are connected to the upper drive shaft. Multiple internal electrodes are evenly distributed circumferentially on the electrode mounting frame, and multiple magnets are evenly distributed circumferentially on the magnet mounting frame. Multiple conical cups are radially connected to the lower drive shaft, and the conical cups drive the lower drive shaft to rotate via water power. An annular cover is connected to the lower drive shaft, and multiple external electrodes and multiple power generation coils are arranged on the inner wall of the annular cover. Multiple internal electrodes are covered with PTFE film, and multiple external electrodes are covered with PVC film; The magnetic poles of multiple magnets are arranged alternately to form a magnetic field; The upper and lower drive shafts rotate in opposite directions; During the relative rotation of the upper and lower drive shafts, the PTFE film and PVC film undergo periodic friction and separation motion to achieve triboelectric power generation; multiple power generation coils cut the magnetic field lines in the magnetic field to achieve permanent magnet power generation.

[0006] Preferably, it also includes an energy storage unit, which is connected to the lower drive shaft. The energy storage unit is used to store the electrical energy generated by the wind power generation unit and the hydropower generation unit.

[0007] Preferably, the energy storage unit includes: a rectifier, a supercapacitor, a voltage regulator chip, and a step-down converter. The alternating current generated by triboelectric power generation is processed by the rectifier into direct current, and the direct current is regulated by the voltage regulator chip to become a preset voltage direct current. The alternating current generated by permanent magnet power generation is processed by the rectifier into direct current, and the direct current is converted into a preset voltage direct current by the step-down converter. The supercapacitor is used to store the preset voltage direct current.

[0008] Preferably, the wind cup is made of ABS or carbon fiber composite material with a hydrophobic coating sprayed on the surface.

[0009] Preferably, the conical cup is made of aluminum alloy. The conical cup utilizes the difference in water pressure on both sides to drive the lower transmission shaft to rotate.

[0010] Preferably, the upper drive shaft is provided with a first unidirectional thrust device, and the lower drive shaft is provided with a second unidirectional thrust device. The first and second unidirectional thrust devices are used to make the upper and lower drive shafts rotate in one direction and in opposite directions.

[0011] Preferably, the upper drive shaft is made of stainless steel tube or carbon fiber tube.

[0012] Preferably, the lower drive shaft is made of aluminum alloy tubing.

[0013] Preferably, the magnet mounting bracket is an aluminum metal disc, and the magnet is an NdFeB magnet.

[0014] Preferably, the electrode mounting bracket includes four hollow support members, each hollow support member including four closed surfaces and an outer end opening, with the upper and lower surfaces having a fan-shaped structure.

[0015] Compared with the prior art, the present invention can achieve the following beneficial effects: The existing distributed energy supply devices mostly rely on a single energy source and cannot work properly when the energy fluctuates or is interrupted; traditional electromagnetic generators have low power generation efficiency under low frequency, random, and weak mechanical energy input conditions, and triboelectric generators have limited output power under high frequency conditions. This invention employs a structural design that combines wind and hydropower generation, with wind and hydropower units arranged in a nested configuration. This design allows the device to adapt to real-time changes in wind speed and water flow, achieving stable all-weather power supply in complex and variable outdoor aquatic environments, significantly improving the reliability of energy supply. The invention also features unidirectional rotating upper and lower drive shafts with opposite directions of rotation, enabling the PTFE and PVC films in the triboelectric power generation system to generate greater relative speed and frequency under the drive of the drive shafts. This design not only increases the output power of triboelectric power generation but also enhances the relative cutting speed between the magnet and coil in the permanent magnet power generation structure. The AC power generated by the wind and hydropower units of this invention, at different frequencies, is rectified by a rectifier and then collected in a capacitor in the energy storage unit for storage. A step-down converter then outputs stable DC power, which can directly provide a stable power supply for wind speed sensors, water flow sensors, temperature sensors, and IoT wireless transmission modules. This design is suitable for applications in remote areas, hydrological monitoring stations, and floating platforms where there is no power grid coverage or power supply is difficult.

[0022] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 In one embodiment of the present invention, a distributed water power supply device based on friction-permanent magnet composite power generation is provided, comprising: a wind power generation unit and a water power generation unit. The wind power generation unit includes: multiple wind cups, an upper drive shaft, internal electrodes, an electrode mounting frame, a magnet mounting frame, and multiple magnets. The water power generation unit includes: multiple conical cups, a lower drive shaft, an annular cover, external electrodes, and multiple power generation coils. Multiple wind cups are radially connected to the upper drive shaft, and the wind cups drive the upper drive shaft to rotate via wind power. An electrode mounting frame and a magnet mounting frame are connected to the upper drive shaft. Multiple internal electrodes are evenly distributed circumferentially on the electrode mounting frame, and multiple magnets are evenly distributed circumferentially on the magnet mounting frame. Multiple conical cups are radially connected to the lower drive shaft, and the conical cups drive the lower drive shaft to rotate via water power. An annular cover is connected to the lower drive shaft, and multiple external electrodes and multiple power generation coils are arranged on the inner wall of the annular cover. Multiple internal electrodes are covered with PTFE film, and multiple external electrodes are covered with PVC film; The magnetic poles of multiple magnets are arranged alternately to form a magnetic field; The upper and lower drive shafts rotate in opposite directions; During the relative rotation of the upper and lower drive shafts, the PTFE film and PVC film undergo periodic friction and separation motion to achieve triboelectric power generation; multiple power generation coils cut the magnetic field lines in the magnetic field to achieve permanent magnet power generation.

[0024] The floating distributed energy supply device based on triboelectric-permanent magnet composite power generation provided in this invention includes: a wind power generation unit, a hydropower generation unit, and an energy storage unit, wherein the wind power generation unit and the hydropower generation unit adopt an upper and lower nested structure design.

[0025] Please see Figure 5 The wind power generation unit includes: a wind energy utilization module, a permanent magnet power generation module, and a wind-powered triboelectric nano-power generation internal electrode module.

[0026] The wind energy utilization module includes: six semi-circular lightweight wind cups 1, an upper drive shaft 5, and a rotating shaft 2. The wind cups 1 are made of lightweight, weather-resistant ABS or carbon fiber composite material, and the surface is coated with a hydrophobic coating to prevent icing and corrosion. Each wind cup 1 is connected to a rotating shaft 2, which is radially and evenly fixed to the top of the upper drive shaft 5. The wind cups 1 are driven by wind energy to rotate the upper drive shaft 5. The wind cups 1 can rotate under light wind conditions with wind speeds of 1.5 m / s or higher. The design of the wind cups 1 allows for startup at lower wind speeds, thereby improving the efficiency of wind energy utilization.

[0027] The upper drive shaft 5 is made of stainless steel or carbon fiber tubing. A permanent magnet generator module and a wind-driven triboelectric nano-power generation internal electrode module are rigidly connected to the upper drive shaft 5. The permanent magnet generator module is located above the wind-driven triboelectric nano-power generation internal electrode module. Please refer to [link / reference]. Figure 3 The permanent magnet generator module includes six magnets 10 and a magnet mounting frame 14. The magnet mounting frame 14 is an aluminum metal disk, and the magnets 10 are NdFeB permanent magnets, which are respectively embedded in the outer edge of the aluminum metal disk. The six magnets 10 are evenly distributed around the magnet mounting frame 14, and the magnetic poles of adjacent magnets 10 are arranged alternately (i.e., N pole and S pole alternate), forming a spatial alternating magnetic field. A 0.3mm thick silicon steel sheet is fixedly connected to the back of each magnet 10 with epoxy glue. The silicon steel sheet is used for magnetic isolation. When the magnet 10 rotates on the upper drive shaft 5, an alternating magnetic field is formed in the 0.2mm axial air gap.

[0028] Please see Figure 4The internal electrode module for wind-powered triboelectric nano-power generation is located below the permanent magnet module for permanent magnet power generation. The internal electrode module for wind-powered triboelectric nano-power generation includes an electrode mounting frame 12 and an internal electrode 15. The electrode mounting frame 12 includes four hollow support members. Each hollow support member includes four closed surfaces and an outer end opening. The upper and lower surfaces are fan-shaped structures. The outer end opening is covered with copper foil tape as the internal electrode 15. The surface of the internal electrode 15 is covered with a PTFE film.

[0029] The hydropower generation unit includes: a hydropower utilization module, a permanent magnet power generation coil module, and a hydro-friction nano-power generation external electrode module.

[0030] The water energy utilization module includes: six conical cups 9, a lower drive shaft 8, and a rotating shaft 2. The conical cups 9 are made of lightweight aluminum alloy. Each conical cup 9 is connected to the rotating shaft 2. The rotating shaft 2 is radially and evenly connected to the bottom end of the lower drive shaft 8. The conical cups 9 drive the lower drive shaft 8 to rotate via water energy. When the device is placed in water flow, when the water flow velocity reaches 0.02m / s or higher, the water pressure difference on both sides of the conical cups 9 will cause the conical cups to rotate clockwise, opposite to the rotation direction of the wind energy utilization module.

[0031] Please see Figure 3 The lower drive shaft 8 is made of aluminum alloy tubing, and an annular cover 6 is rigidly connected to it. A permanent magnet power generation coil module and a hydrodynamic friction nano-power generation external electrode module are mounted on the inner wall of the annular cover 6. The permanent magnet power generation coil module is positioned opposite the permanent magnet power generation magnet module, and the hydrodynamic friction nano-power generation external electrode module is positioned opposite the wind-driven friction nano-power generation internal electrode module. The permanent magnet power generation coil module includes three power generation coils 11, each wound with 0.2mm diameter oxygen-free copper wire and held in place by two 0.8mm thick epoxy fiberglass boards on both sides. Each power generation coil 11 has 120 turns. The three power generation coils 11 are connected in a star configuration to form three phase windings with a 120° phase difference. The three phase windings are evenly arranged circumferentially along the inner wall of the annular cover 6. Each power generation coil 11 is vacuum impregnated and epoxy potted, and its surface is coated with a three-proof varnish for waterproof and insulating protection.

[0032] The external electrode module for hydrodynamic triboelectric nanogenerators has a ring-shaped structure, including a triboelectric nanogenerator ring connected to the ring cover 6 and an external electrode 13. Copper foil is circumferentially attached to the inner wall of the triboelectric nanogenerator ring as the external electrode 13, and a PVC film is attached to the surface of the external electrode 13.

[0033] Please see Figure 2A fixed cover 7 is provided on the outside of the annular cover 6. The fixed cover 7 is a closed structure used to protect the internal power generation device. A first one-way thrust device 4 is provided below the wind cup 1. The first one-way thrust device 4 is connected to the fixed cover 7 and the upper drive shaft 5. The first one-way thrust device 4 is used to limit the clockwise rotation of the upper drive shaft 5 and to lock the upper drive shaft 5 under windless conditions. A second one-way thrust device 16 is provided below the conical cup 9. The second one-way thrust device 16 is connected to the fixed cover 7 and the lower drive shaft 8. The second one-way thrust device 16 is used to limit the counterclockwise rotation of the lower drive shaft.

[0034] Wind cup 1, driven by wind energy, rotates the upper drive shaft 5 counterclockwise. The upper drive shaft 5 then drives the permanent magnet generator module and the internal electrode module of the wind-powered friction nano-power generation to rotate counterclockwise synchronously. Conical cup 9, driven by water energy, rotates the lower drive shaft 8 clockwise. The lower drive shaft 8 then drives the permanent magnet generator coil module and the external electrode module of the water-powered friction nano-power generation to rotate clockwise synchronously.

[0035] The internal electrode module of wind-powered triboelectric nano-power generation and the external electrode module of water-powered triboelectric nano-power generation form a triboelectric and decoupled triboelectric nano-power generation structure. In the triboelectric nano-power generation structure, the PVC film attached to the surface of the external electrode 13 and the PTFE film attached to the surface of the internal electrode 15 make periodic contact and separation movements during the relative rotation of the upper drive shaft 5 and the lower drive shaft 8. When in contact, the charge transfer is caused by the triboelectric charging sequence (negative difference), making the PTFE film negatively charged and the PVC film positively charged. When separated, a potential difference is formed between the two materials, thereby driving electrons to flow back and forth through the external circuit to generate pulsed alternating current. This power generation process can maintain a stable milliwatt-level power output even under low speed conditions of the upper drive shaft 5 and the lower drive shaft 8.

[0036] The permanent magnet generator module and the permanent magnet generator coil module form a permanent magnet generator structure. In the permanent magnet generator structure, as the magnet 10 and the generator coil 11 rotate relative to each other on the upper drive shaft 5 and the lower drive shaft 8, the coil cuts the magnetic field lines in the magnetic field and generates an induced electromotive force according to Faraday's law of electromagnetic induction, thus generating three-phase alternating current.

[0037] Energy storage unit 3 is housed within an annular cover 6 and connected to the lower drive shaft 8. Energy storage unit 3 includes a rectifier, a supercapacitor, a voltage regulator chip, and a step-down converter. The pulsed AC power generated by the triboelectric nano-power generation structure is rectified into DC power by the rectifier, and then regulated by the voltage regulator chip to a preset voltage DC power. The three-phase AC power generated by the permanent magnet power generation structure is rectified into DC power by the rectifier, and then regulated by the step-down converter to a preset voltage DC power. The two processed preset voltage DC power supplies are connected to a common DC bus and ultimately connected to the supercapacitor for energy storage.

[0038] The electrical energy stored in the supercapacitor is output through a split conductor slide rail, which includes a stator slide rail assembly 17 and a mover slide rail assembly 18. The stator slide rail assembly 17 is integrated into the energy storage unit, and the mover slide rail assembly 18 is fixed inside the fixed cover 7. The stator slide rail assembly 17 and the mover slide rail assembly 18 form a sliding electrical contact to realize the transmission of electrical energy.

[0039] The upper drive shaft 5 and the lower drive shaft 8 rotate relative to each other, driving the friction nano-power generation structure and the permanent magnet power generation structure to rotate, thus achieving combined power generation. When the wind speed is high, the device generates electricity mainly using the wind power generation unit and secondarily using the hydropower generation unit; the increased wind speed helps to improve the overall power generation efficiency. When the wind speed is low, the device generates electricity mainly using the hydropower generation unit and secondarily using the wind power generation unit. When the wind speed is zero (no wind), the first unidirectional thrust device 4 in the wind power generation unit is locked, and the device generates electricity solely using the hydropower generation unit; the increased water flow speed helps to improve the power generation efficiency.

[0040] The fixed cover is installed on an H-shaped support frame (measuring bridge), spanning the water channel to form a coupled structure with windward and water-downward orientation. The pulsed AC power generated by the triboelectric nano-power generation structure is rectified into DC power by a rectifier, and then regulated by a voltage regulator chip to a preset voltage DC power. The three-phase AC power generated by the permanent magnet power generation structure is rectified into DC power by a rectifier, and then stepped down to a preset voltage DC power. The two processed preset voltage DC power supplies are connected to a common DC bus and then connected to a supercapacitor for energy storage. The energy stored in the supercapacitor is output through a split-type conductor slide rail, which includes a stator slide rail assembly 17 and a mover slide rail assembly 18. The stator slide rail assembly 17 is integrated into the energy storage unit, and the mover slide rail assembly 18 is fixed inside the fixed cover 7. The stator slide rail assembly 17 and the mover slide rail assembly 18 form a sliding electrical contact to achieve energy transmission. This power supply method can provide a stable power supply for sensors or related electronic modules for wind speed measurement, water flow velocity measurement, temperature measurement, humidity measurement, etc.
