[0037] To facilitate understanding of the present invention, a general structure of an energy harvesting device and its application are described herein by way of example.

[0038] Figure 1 This is a schematic diagram of the internal structure of the energy harvesting device according to an embodiment of the present invention. Figure 2 This is a schematic diagram of the external structure of the energy harvesting device according to an embodiment of the present invention.

[0039] like Figure 1 and Figure 2 As shown, this embodiment of the invention provides an energy harvesting device, including a housing 1, a solar panel 2, an inner electrode plate 3, an outer electrode plate 4, a power management circuit board 5, and a wireless sensing circuit board 6. The solar panel 2 is disposed outside the housing 1, and the inner electrode plate 3, the outer electrode plate 4, the power management circuit board 5, and the wireless sensing circuit board 6 are respectively connected inside the housing 1. The solar panel 2 is connected to the power management circuit board 5, and the inner electrode plate 3 and the outer electrode plate 4 are arranged opposite to each other and respectively connected to the power management circuit board 5. The wireless sensing circuit board 6 is connected to the power management circuit board 5, and the power management circuit board 5 is used to collect the electrical energy of the solar panel 2 and the electric field energy between the inner electrode plate 3 and the outer panel to provide a stable power supply for the wireless sensing circuit board 6 to monitor the output of the cable.

[0040] The energy harvesting device provided in this embodiment of the invention has a solar panel installed on the outside of the housing, and an inner electrode plate, an outer electrode plate, a power management circuit board, and a wireless sensing circuit board installed inside the housing. The inner electrode plate and the outer electrode plate are respectively connected to the power management circuit board through wires, so that an electric field energy is formed between the inner electrode plate and the outer electrode plate. The power management circuit board can simultaneously harvest the electrical energy and electric field energy of the solar panel, providing a stable operating power supply for the wireless sensing circuit board to monitor its monitoring cables and wires. Furthermore, the outer electrode plate and the solar panel are combined to form an equipotential body, avoiding the risk of breakdown between the two. This enables multiple ways of harvesting electrical energy, effectively ensuring the continuous operation of the wireless sensing circuit board, improving the application range of the energy harvesting device, and ensuring safety and reliability.

[0041] Figure 1 As shown, the energy harvesting device further includes an inner electrode plate baffle 7, which is disposed opposite to the inner electrode plate 3 and located behind the inner electrode plate 3. The inner electrode plate baffle 7 is used to isolate the inner electrode plate 3 from the cable and wire.

[0042] The energy harvesting device provided by this invention needs to be directly fitted onto the cable during use. An inner electrode plate baffle 7 is set to isolate the cable from the inner electrode plate 3, preventing the inner electrode plate 3 from directly contacting the cable and thus providing a certain degree of insulation.

[0043] like Figure 1 As shown, one end of the inner plate 3 is connected to the negative input terminal of the power management circuit board 5 through a first wire, and one end of the outer plate 4 is connected to the positive input terminal of the power management circuit board 5 through a second wire, so that the electric field energy formed between the inner plate 3 and the outer plate 4 can be transmitted to the power management circuit board 5.

[0044] After the energy harvesting device is installed, one end of the inner plate 3 is connected to the negative input terminal of the power management circuit board 5 through the first wire, and one end of the outer plate 4 is connected to the positive input terminal of the power management circuit board 5 through the second wire, forming an equipotential body. Under the action of the distributed capacitance C1 formed by the inner plate 3 and the outer plate 4 and the capacitance C2 formed by the outer plate 4 and the ground, an induced voltage will be generated on the outer plate 4. Therefore, the electric field energy between the inner plate 3 and the outer plate 4 can be harvested.

[0045] like Figure 1As shown, the power management circuit board 5 also includes an energy storage module, an electric field energy processing module, a solar energy processing module, a voltage regulator module, and an energy output module. The energy storage module is used to store the electrical energy input to the power management circuit board 5. The electric field energy processing module and the solar energy processing module are used to boost, rectify, and convert the electrical energy output from the solar panel 2 and the electric field energy output from the inner electrode plate 3 and the outer electrode plate 4, respectively. The voltage regulator module is used to regulate and divide the electrical energy processed by the electric field energy processing module and the solar energy processing module. The energy output module is used to transmit the regulated and divided electrical energy from the voltage regulator module to the wireless sensor circuit board 6.

[0046] After the power management circuit board 5 collects the electrical energy from the solar panel 2 and the electric field energy formed between the inner plate 3 and the outer plate 4, it stores the electrical energy through the power storage module. Since the voltage and power of the electrical energy output by the solar panel 2 and the electric field energy output by the inner plate 3 and the outer plate 4 do not meet the requirements of the working power supply of the wireless sensor circuit board 6, the electric field energy processing module and the solar energy processing module are used to boost, rectify, and convert the electrical energy output by the solar panel 2 and the electric field energy output by the inner plate 3 and the outer plate 4, respectively. Then, the voltage regulator module is used to regulate and divide the electrical energy of the electric field energy processing module and the solar energy processing module, and finally deliver a stable working power supply to the wireless sensor circuit board 6.

[0047] like Figure 1 As shown, the wireless sensing circuit board 6 includes a monitoring sensor and a wireless transmission node. The monitoring sensor is used to monitor the current signal of the cable and wire and transmit the monitoring data wirelessly through the wireless transmission node.

[0048] The wireless sensing circuit board 6 is used to monitor the current signal in the cable. Due to the limitations of the installation environment, it cannot be powered by an external power source. However, the power harvesting device provided in this embodiment of the invention can ensure that the wireless sensing circuit board 6 can work continuously and effectively monitor the cable.

[0049] like Figure 1 and Figure 2 As shown, the housing 1 includes a first housing 11 and a second housing 12, which form an openable and closable closed structure. Through holes 13 are provided at both ends along the length of the housing 1, and the through holes 13 are adapted to the cable wires. The first housing 11 is connected to the upper end of the second housing 12, and the solar panel 2 is connected to the outside of the first housing 11. The inner electrode plate 3, the outer electrode plate 4, the power management circuit board 5, and the wireless sensing circuit board 6 are all connected to the inside of the second housing 12.

[0050] To facilitate the installation and disassembly of the energy harvesting device and the cable, the housing 1 is designed as an openable closed structure. When the energy harvesting device is opened, the cable passes through the interior of the housing 1 and is located inside the through holes 13 on both sides. When closed, the housing 1 is a closed structure, which protects the inner electrode plate 3, the outer electrode plate 4, the power management circuit board 5 and the wireless sensing circuit board 6, and prevents dust and foreign objects from entering the interior of the housing 1.

[0051] The solar panel 2 is mounted on the first housing 11 to facilitate the collection of sunlight.

[0052] like Figure 1 and Figure 2 As shown, the opposite sides of the first housing 11 and the second housing 12 are connected by hinges 8 to form the openable closed structure; the cross-section of the first housing 11 is trapezoidal, and there are three solar panels 2, which are respectively connected to the upper end and the two sides of the trapezoidal shape.

[0053] The inner sidewalls of the first housing 11 and the second housing 12 are connected by hinges 8, which facilitates the opening and closing of the first housing 11 and the second housing 12. The first housing is set to have a trapezoidal cross-section, and solar panels 2 are provided on its upper end face and both sides, so that the first housing 1 can obtain solar energy at different light angles.

[0054] like Figure 1 As shown, the bottom edges of both ends of the first housing 11 are provided with a first opening 131, and the top edges of both ends of the second housing are provided with a second opening 132 corresponding to the first opening 131. The first opening 131 and the second opening 132 form the through hole 13.

[0055] To facilitate the installation of the energy harvesting device and the cable, a first opening 131 is provided on the lower edge of both ends of the first housing. The first opening 131 is semi-circular. A second opening 132 is provided on the upper edge of both ends of the second housing 132. The second opening 132 is the same semi-circular shape as the first opening 131. When the energy harvesting device is opened for installation, the cable is precisely inserted between the first opening 131 and the second opening 132, enabling live installation, which is convenient and quick.

[0056] like Figure 1 and Figure 2 As shown, the solar panel 2 is made of a light-sensitive material and is coated with a transparent, waterproof coating; the casing 1 is made of epoxy resin.

[0057] Solar panel 2 uses materials that are sensitive to low light, and still has a large power output on cloudy days. The surface of solar panel 2 is coated with a transparent and waterproof coating, which greatly reduces dirt and ensures long-term high-efficiency operation.

[0058] The housing 1 is made of epoxy resin material, which has good insulation and corrosion resistance, thus improving the application range of the energy harvesting device.

[0059] like Figure 1 As shown, the lower end of the first housing 11 and the upper end of the second housing 12 are provided with circumferential annular grooves 14, and rubber strips 141 are provided in the annular grooves 14.

[0060] When the first housing 11 and the second housing 12 are closed, the annular groove 14 and the rubber strip 141 can ensure that the end faces that come into contact with each other are in close contact, which has good sealing performance and ensures dustproof and waterproof performance.

[0061] Other embodiments of the invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. The invention is intended to cover any variations, uses, or adaptations that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
