Description

Technical Field

[0001] The present invention relates to the field of energy, and more particularly to a power supply and a power supply system. Background Art

[0002] In actual industrial production, a large number of monitoring devices, such as sensors, monitoring instruments, and control equipment, are deployed. With the development of wireless communication technology, more and more devices use wireless communication to transmit signals, making the deployment of monitoring equipment more flexible and convenient. However, most existing monitoring equipment is still powered by batteries. Due to the limited power of the battery, the battery needs to be replaced regularly, which results in high maintenance costs in terms of manpower and time.

[0003] However, during the operation of industrial equipment, various heat sources or cold source media usually flow in the pipeline. Many applicants have proposed a power generation method that uses thermoelectric power generation technology to convert thermal energy into electrical energy to power various types of equipment. For example, the power supply unit proposed in patent publication number CN106549475A includes a semiconductor thermoelectric power generation module and a supercapacitor that can store and transmit electrical energy. However, its applicability is poor and the installation and fixing method still needs to be designed in combination with the actual usage scenario, which is not convenient for large-scale use. For example, the self-service point wireless temperature measurement sensor proposed in patent publication number CN215984916U fixes the thermal conductive base to the pipeline with a metal strap, and then uses the thermoelectric energy collector to output electrical energy to power the sensor. This solution is easy to install, but the thermal conductive base needs to be designed and manufactured to adapt to the curvature of the outer wall of the pipeline for installation, which is not adaptable. In addition, the thermal conductive base and the pipeline fitting surface are prone to incomplete contact or gaps, resulting in poor heat conduction effect, affecting power generation efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a power supply and a power supply system to address the deficiencies of the existing technology, so as to solve the technical problems of the existing temperature difference power generation method, such as poor adaptability, low power generation efficiency and inability to provide continuous and reliable power supply.

[0005] The power supply and power supply system described in the present invention include a connector, a heat dissipation structure and a thermoelectric power generation structure. The heat dissipation structure is detachably mounted on the outside of the connector. A thermoelectric power generation structure is provided between the heat dissipation structure and the connector. The connector includes a heat conducting portion. The thermoelectric power generation structure and the heat conducting portion are in contact with each other. The thermoelectric power generation structure and the heat dissipation structure are in contact with each other. One end of the connector is connected to a heat / cold source pipe via a clamping structure. The other end of the connector is provided with a mounting seat. The electrical equipment is placed on the mounting seat, and the electrical equipment is electrically connected to the thermoelectric power generation structure.

[0006] As a further improvement, the connecting member further includes a connecting portion, one end of which is fixedly connected to the heat conducting portion, and a through hole penetrating the connecting portion and the heat conducting portion is provided on the connecting portion and the heat conducting portion.

[0007] Furthermore, a mounting portion is fixedly mounted at the connection between the connecting portion and the heat conducting portion, and the mounting portion is a hexagonal nut.

[0008] Furthermore, the clamping structure includes a first connecting tube, a first base plate, a first slider, a second slider and two first fixed blocks, the first connecting tube is rotatably installed in the middle of the first base plate, the first fixing blocks are fixedly installed at both ends of the first base plate, the first fixing block is provided with a first threaded hole, the first threaded hole is screwed with a first tightening bolt, the first slider and the second slider are slidably installed on the first base plate, the bottom of the first slider is provided with a first clamping block, the bottom of the second slider is provided with a second clamping block, one end of the first connecting tube is threadedly connected to the connecting piece, and the other end of the first connecting tube is connected to the heat / cold source pipe.

[0009] Furthermore, the first clamping block is provided with an arc-shaped first clamping portion, the second clamping block is provided with a second clamping portion matching the first clamping portion, and a buffer block is provided on the side of the first slider close to the first tightening bolt and the side of the second slider close to the first tightening bolt.

[0010] Furthermore, the mounting base includes a second connecting tube and a second base plate, the second connecting tube is fixedly installed on the bottom of the second base plate, a detection hole connected to the second connecting tube is provided on the second base plate, second fixing blocks are fixedly installed on both sides of the second base plate, a second threaded hole is provided on the second fixing block, a second tightening bolt is screwed into the second threaded hole, two third sliders are slidably installed on the second base plate, electrical equipment is placed between the two third sliders, and buffer blocks are fixedly installed on both sides of the two third sliders.

[0011] Furthermore, the heat dissipation structure includes two bases and multiple fins, both of the bases are U-shaped, and multiple fins are fixedly mounted on the bases, and the fins are evenly distributed on the bases. The outer surface of the heat-conducting part is provided with multiple third threaded holes, and the base is provided with multiple through holes matching the third threaded holes. One of the bases is installed on one side of the heat-conducting part by bolts, and the other base is installed on the other side of the heat-conducting part by bolts, and the heat-conducting part fits the two bases.

[0012] Furthermore, the thermoelectric power generation structure includes a conductive layer, a first coating is provided on the side of the conductive layer facing the connector, and a second coating is provided on the side of the conductive layer facing the heat dissipation structure. The first coating is in contact with the heat-conducting part, and the second coating is in contact with the heat dissipation structure. A heat-conducting block is provided between the second coating and the heat dissipation structure, and the conductive layer is electrically connected to the electrical equipment through a wire.

[0013] A power supply system includes a battery and a power management circuit, the battery being electrically connected to the power management circuit, which is in turn electrically connected to one of the aforementioned power supplies. A connector in the power supply captures heat or cold from a heat / cold source pipe, which transfers the heat or cold to a thermoelectric power generation structure and a heat dissipation structure. The heat dissipation structure in the power supply transfers the heat or cold of the fluid to an external ambient medium, thereby creating a temperature difference across the thermoelectric power generation structure. This temperature difference causes a conductive layer of the thermoelectric power generation structure to generate electrical energy, which is then input into an electrical device.

[0014] The electrical equipment and the thermoelectric power generation structure are both electrically connected to the power management circuit to obtain the electrical energy required by the electrical equipment, the electrical energy generated by the thermoelectric power generation structure and the remaining power of the battery. The electrical energy adjustment strategy is triggered according to the electrical energy required by the electrical equipment, the electrical energy generated by the thermoelectric power generation structure and the remaining power of the battery to determine the working mode of the power management circuit.

[0015] As a further improvement, the power adjustment strategy is that when the power generated by the thermoelectric power generation structure is greater than the power required by the electrical equipment, the power generated by the thermoelectric power generation structure is used to power the electrical equipment; when the power required by the electrical equipment is met, the remaining power of the thermoelectric power generation structure is used to charge the battery;

[0016] When the electric energy generated by the thermoelectric power generation structure is less than the electric energy required by the electrical equipment, the battery supplies power to the electrical equipment and the electric energy generated by the thermoelectric power generation structure charges the battery. When the remaining power of the battery is greater than a preset power threshold, the electric energy generated by the thermoelectric power generation structure does not charge the battery.

[0017] Beneficial effects

[0018] The advantages of the present invention are:

[0019] 1. The present invention uses the through-holes in the connector to allow the heat conducting part to directly contact the heat source or cold source fluid, making the temperature of the heat conducting part closer to the temperature of the heat source or cold source, thereby forming a larger temperature difference at both ends of the thermoelectric power generation structure, thereby improving energy utilization efficiency and having a stronger power supply guarantee capability.

[0020] 2. The present invention provides a conductive layer, a first coating is provided on a side of the conductive layer facing the connector, and a second coating is provided on a side of the conductive layer facing the heat dissipation structure. The first coating is in contact with the heat-conducting portion, and the second coating is in contact with the heat-dissipating structure. By adopting coating technology, an insulating thermally conductive coating is sprayed on the surface of the heat-conducting portion and the heat-conducting block. Since the coating has a thinner thickness, the thermal resistance of the thermoelectric power generation structure is reduced, thereby increasing the temperature difference between the two ends of the conductive layer and improving the power generation capacity. Moreover, through spraying and welding processes, the entire thermoelectric power generation structure and the connector are made into a modular whole, which is convenient for subsequent production and assembly and easier to ensure product performance.

[0021] 3. The present invention has a mounting portion fixedly mounted at the connection between the connecting portion and the heat conducting portion, which facilitates the installation and fixation of the connecting piece with the heat / cold source equipment and the electrical equipment, and is easy to use.

[0022] 4. The power supply of the present invention can also flexibly set the number of temperature difference power generation structures according to the required power of the electrical equipment, and can further consider connecting the connectors of multiple power supplies in series through an end-to-end connection method, thereby improving the total power generation capacity and being able to adapt to the required power of most electrical equipment. The overall solution is more flexible and has a wider range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] See Figures 1-8 A power supply and power supply system of the present invention includes a connector 10, a heat dissipation structure 30 and a thermoelectric power generation structure 20.

[0034] like Figure 3 As shown, the connector 10 further includes a connecting portion 11, one end of which is fixedly connected to a heat conducting portion 12. A through hole 13 is formed in the connecting portion 11 and the heat conducting portion 12, penetrating the connecting portion 11 and the heat conducting portion 12. Through the through hole 13 in the connector, the heat conducting portion 12 is directly in contact with the heat source or heat sink fluid, making the temperature of the heat conducting portion 12 closer to that of the heat source or heat sink, thereby forming a larger temperature difference between the two ends of the thermoelectric power generation structure 20, improving energy utilization efficiency, and providing stronger power supply guarantee capabilities.

The first clamping portion 69 and the second clamping portion 610 facilitate clamping of the heat / cold source pipe 1 and strengthen the connection between the connector 10 and the heat / cold source pipe 1. The buffer blocks 5 are provided to reduce wear between the bolt and the slider, thereby increasing the slider's service life.

[0039] like Figure 7As shown, the mounting base 70 includes a second connecting tube 71 and a second base plate 72. The second connecting tube 71 is fixedly mounted on the bottom of the second base plate 72.

The second connecting tube 71 is threadedly connected to the heat conducting portion 12. The mounting base 70 is provided to achieve a stable installation between the electrical device 2 and the connector 10.

[0040] like Figure 5 As shown, the heat dissipation structure 30 includes two bases 3 and a plurality of fins 4. Both bases 3 are U-shaped. A plurality of fins 4 are fixedly mounted on the base 8. The fins 4 are evenly distributed on the base 3. A plurality of third threaded holes are provided on the outer surface of the heat conducting part 12.

The heat conducting part 12 fits the two bases 3.

[0041] The thermoelectric power generation structure 20 includes a conductive layer 22. The conductive layer 22 has a first coating 21 on the side facing the connector 10, and a second coating 23 on the side facing the heat dissipation structure 30.

A heat conduction block 50 is provided between the second coating 23 and the heat dissipation structure 30. The heat conduction block 50 is used to accelerate heat transfer.

[0042] The conductive layer includes a plurality of P-type semiconductors, N-type semiconductors and conductive sheets, and the P-type semiconductors and the N-type semiconductors are alternately electrically connected to the conductive sheets.

[0043] The present invention provides three power supply embodiments in different scenarios.

[0044] Example 1:

[0045] This embodiment provides a power supply such as Figure 1-2 As shown, the power supply of this embodiment includes a connector 10, a thermoelectric power generation structure 20, and a heat dissipation structure 30. The connector 10 and heat dissipation structure 30 are made of a highly thermally conductive metal material. The heat dissipation structure 30 is secured to the connector 10 using screws 40. In addition to screws, other fixing methods such as binding, welding, and magnetic attraction can also be used, and this embodiment does not limit this.

[0046] like Figure 3As shown, the connector 10 includes: a connecting portion 11 and a heat conducting portion 12, and the connecting portion 11 is provided at both ends of the connector 10, and is connected to the heat / cold source device and the electrical equipment respectively. The heat / cold source device of the present application can be an industrial pipeline with a hot / cold medium flowing, or a storage tank / box containing a hot / cold medium, or even a device with a hot / cold temperature (which can be connected to the device table, because the connector is made of metal, it can also conduct heat to the heat conducting portion through the connecting portion), and other devices with a heat source and a cold source, and the above does not represent a specific limitation. The electrical equipment of the present application can be a sensor for monitoring parameters such as the temperature / pressure of the pipeline fluid, or an instrument for monitoring pipelines and equipment, or a device for controlling pipelines and equipment, and the above does not represent a specific limitation.

[0047] Specifically, taking the monitoring sensor for measuring the fluid parameters in the heat / cold source pipeline 1 as an example, this is a common scenario in industrial production, such as Figure 4 As shown, the heat / cold source device is the heat / cold source pipe 1 to be monitored. A heat-carrying fluid flows in the heat / cold source pipe 1. The heat / cold source pipe 1 is provided with a branch pipe for mounting a sensor. The electrical device 2 is a sensor. The lower end of the sensor is provided with a probe. In actual industrial scenarios, internal and external threads are usually provided at the connection between the branch pipe and the probe, which cooperate with each other to fix the sensor on the heat / cold source pipe 1, thereby monitoring the temperature, pressure and other parameters of the fluid in the heat / cold source pipe 1 through the sensor. In this embodiment, the power supply of the present application can be connected to the heat / cold source pipe 1 through a clamping structure 70, and the sensor 3 is mounted on the mounting base 60. Specifically, the connecting portion 11 at one end of the connecting member 10 is connected to the interface of the branch pipe on the heat / cold source pipe 1; the connecting portion 11 at the other end of the connecting member 10 is connected to the probe of the sensor, usually by threaded connection, but also by welding, clamping, etc., which are not specifically limited in this embodiment. In this embodiment, to further save space and material, the connecting portion 11 and the heat conducting portion 12 are an integrated structure.

[0048] In this embodiment, a hollow through-hole 13 is provided inside the connector 10. The through-hole 13 allows the heat / cold source medium to flow through, and the probe rod of the sensor 3, or other equipment and components to pass through. In the through-hole 13, the fluid can transfer its own heat or cold to the heat-conducting part 12, so that the temperature of the heat-conducting part 12 is close to the temperature of the fluid.

[0049] like Figure 3As shown, the outer surface of the heat conducting portion 12 is provided with a plurality of threaded holes. The heat conducting portion is in contact with one end of the thermoelectric power generation structure 20, and the heat sink 30 is in contact with the other end of the thermoelectric power generation structure 20. Screws 40 pass through the heat sink 30 and are screwed into the threaded holes on the outer surface of the heat conducting portion 12, thereby fixing the connector, the thermoelectric power generation structure 20, and the heat sink together. The screws 40 do not contact the thermoelectric power generation structure 20. The heat conducting portion 12 is also used to transfer heat or cold from the fluid in the through hole to the external environment medium through the thermoelectric power generation structure 20 and the heat dissipation structure 30, thereby forming a temperature difference between the two ends of the thermoelectric power generation structure 20, so that the thermoelectric power generation structure 20 generates electricity. In this embodiment, the heat conducting portion and the connection portion at the upper end of the connector are integrated, and the outer surface of the heat conducting portion is flat to facilitate the installation of the thermoelectric power generation structure 20 and the heat dissipation structure 30.

[0050] Furthermore, in order to facilitate the installation and fixation of the entire power supply device with the heat / cold source equipment and the electrical equipment, a location for installation can be provided on the connector, such as Figure 3 As shown, the connector in this embodiment is provided with a mounting portion 14, which is a hexagonal nut structure. The mounting portion can be clamped with a hexagonal wrench to tighten the connector to the interface of the heat / cold source device and the interface of the electrical device respectively.

[0051] In this embodiment, one end of the thermoelectric power generation structure 20 is in direct or indirect contact with the surface of the heat conducting portion 12, while the other end of the thermoelectric power generation structure 20 is in direct or indirect contact with the heat dissipation structure 30. The heat conducting portion 12 transfers heat or cold from the fluid medium to one end of the thermoelectric power generation structure 20. The heat or cold is then transferred to the external environment through the thermoelectric power generation structure 20 and the heat dissipation structure 30, creating a temperature difference across the thermoelectric power generation structure 20 and generating electricity.

[0052] Specifically, the thermoelectric power generation structure 20 has insulating layers at both ends and a semiconductor layer in the middle. In this embodiment, the insulating layer is a high-temperature-resistant, insulating, and thermally conductive ceramic block, and the semiconductor layer is an array of multiple bulk P / N-type semiconductors. The P-type and N-type semiconductors are alternately electrically connected via conductive sheets in a π-shaped configuration. The electrodes of the P-type and N-type semiconductors at the ends are electrically connected to wires, respectively. The P-type and N-type semiconductors can be made of bismuth telluride or lead telluride-based materials. To further improve thermoelectric conversion efficiency, the bismuth telluride or lead telluride-based materials can be doped with appropriate amounts of metals such as silver, indium, or chromium.

[0053] like Figure 2As shown, the power supply in this embodiment includes two thermoelectric power generation structures 20, and the two thermoelectric power generation structures 20 are connected in series. Specifically, the wire at the end of one thermoelectric power generation structure 20 (not shown in the figure) is electrically connected to the wire at the end of another thermoelectric power generation structure 20 (not shown in the figure). In other embodiments, other numbers of thermoelectric power generation structures 20, such as 1, 4, 8, etc., can also be used according to the actual required electrical energy; multiple thermoelectric power generation structures 20 can be electrically connected in series or in parallel, or in a mixed manner of series and parallel according to the required voltage and electrical energy, etc. This embodiment does not represent a specific limitation.

[0054] Furthermore, according to the power required by the electrical equipment, it is possible to connect the connectors of multiple power sources in series through an end-to-end connection method, and then connect all the thermoelectric power generation structures 20 together to improve the total power generation capacity.

[0055] In this embodiment, the heat dissipation structure 30 includes a base and fins. The base is flat and closely attached to the thermoelectric power generation structure 20. The fins are spread out in a divergent shape. The entire heat dissipation structure 30 is an integrally formed structure, preferably made of a high thermal conductivity metal material such as aluminum or copper. Specifically, Figure 1 As shown, two heat dissipation structures 30 surround the thermoelectric power generation structure 20 and the connector 10 to fully utilize the space around the connector to increase the heat dissipation area, thereby providing heat dissipation, and further making the temperature of the surface in contact with the thermoelectric power generation structure 20 and the heat dissipation structure 30 as close to the ambient temperature as possible, thereby making the temperature difference between the two end surfaces of the thermoelectric power generation structure 20 larger and generating more electrical energy.

[0056] Specifically, in order to further improve the heat conduction efficiency, thermal conductive glue is filled on the interfaces where the thermoelectric power generation structure 20 is bonded to the connector and the heat dissipation structure 30 .

[0057] Furthermore, between the connector and the heat dissipation structure 30, a heat-insulating material (not shown in the figure) is attached to the surface of the heat-conducting part that is not in contact with the thermoelectric power generation structure 20, so as to avoid direct dissipation of heat or cold from the heat-conducting part, thereby allowing more heat or cold to be transferred to the heat dissipation structure 30 through the thermoelectric power generation structure 20 to improve energy utilization.

[0058] Example 2:

[0059] This embodiment provides a power supply such as Figure 5 As shown, the power supply of this embodiment includes: a connector 10, a thermoelectric power generation structure 20, a heat conducting block 50 and a heat dissipation structure 30. Specifically, as Figure 5 As shown, the thermoelectric power generation structure 20 includes a first coating layer 21 , a conductive layer 22 , a conductive sheet (not shown in the figure) and a second coating layer 23 .

[0060] In this embodiment, the connector 10 is the same as that in Example 1, including a connecting portion 11 and a heat-conducting portion 12. The difference between this embodiment and Example 1 is that a first coating 21 is sprayed on the surface of the heat-conducting portion 12 in close contact with the thermoelectric power generation structure 20. The coating is usually thin and can be tightly attached to the surface of the heat-conducting portion. The first coating 21 is an insulating thermally conductive coating, preferably alumina, aluminum nitride, silicon, quartz, etc.

[0061] Similarly, a second coating 23 is sprayed on one surface of the heat conducting block 50. The second coating 23 is the same as the first coating 21, and is an insulating heat conducting coating that can also be tightly adhered to the surface of the heat conducting block. The heat conducting block 50 is made of a high thermal conductivity metal material.

[0062] In this embodiment, a conductive sheet is coated on the other side of the first coating 21 (the surface not in contact with the heat-conducting portion) according to the required arrangement of the P / N-type semiconductor 22, and one end of the P / N-type semiconductor 22 is welded to the conductive sheet in the required arrangement. Similarly, a conductive sheet is coated on the other side of the second coating 21 (the surface not in contact with the heat-conducting block) according to the required arrangement of the P / N-type semiconductor 22, and the other end of the P / N-type semiconductor 22 is welded to the conductive sheet in the required arrangement.

[0063] Specifically, after the spraying of the first coating and the second coating, and the welding of the P / N type semiconductor, the connector 10, the thermoelectric power generation structure 20 and the heat conductive block 50 are fixed together, that is, the entire thermoelectric power generation structure 20, the connector and the heat conductive block 50 are made into a modular whole, which is convenient for subsequent production and assembly, and also easier to ensure product performance.

[0064] In this embodiment, the heat dissipation structure 30 is the same as that in the first embodiment. The heat dissipation structure 30 is screwed to the connector 10, thereby pressing the thermoelectric power generation structure 20 and the heat conductive block 50 together. In addition to screw fixing, other fixing methods such as binding, welding, and magnetic attraction can also be used, and this embodiment does not represent a specific limitation.

[0065] In this embodiment, the fluid in the through hole of the connector 10 contacts the heat conducting part, and the heat or cold of the fluid is transferred to the external environment medium through the thermoelectric power generation structure 20, the heat conducting block 50 and the heat dissipation structure 30 through the heat conducting part, so as to form a temperature difference at both ends of the thermoelectric power generation structure 20 and generate electrical energy.

[0066] Compared with the ceramic block used in the thermoelectric power generation structure 20 in the first embodiment, the coating used in this embodiment is thinner and has lower thermal resistance, thereby forming a larger temperature difference across the P / N type semiconductor 22 to generate more electricity.

[0067] Example 3:

[0068] like Figure 8As shown, this embodiment provides a power supply system, including a power supply, a battery 7, a power management circuit, a wireless communication unit 8 and a processor 9. The power supply can be the power supply in the first or second embodiment.

[0069] The power management circuit 6 is connected to the wires of the thermoelectric power generation structure 20 to collect the electric energy generated by the thermoelectric power generation structure 20 and boost the voltage thereof, and then supply power to the electric device or charge the battery 7 .

[0070] The battery 7, the wireless communication unit 8, and the processor 9 are all electrically connected to the power management circuit 6, and the power management circuit 6 is electrically connected to the power supply in the above-mentioned embodiment one or two. The thermoelectric power generation structure 20 and the power-consuming device 2 in the power supply are both electrically connected to the power management circuit 6 to obtain the electric energy required by the power-consuming device 2, the electric energy generated by the thermoelectric power generation structure 20, and the remaining power of the battery 7. The electric energy adjustment strategy is triggered according to the electric energy required by the power-consuming device 2, the electric energy generated by the thermoelectric power generation structure 20, and the remaining power of the battery 7 to determine the working mode of the power management circuit 6.

[0071] The power adjustment strategy is as follows: when the power generated by the thermoelectric power generation structure 20 exceeds the power required by the power consumer 2, the power generated by the thermoelectric power generation structure 20 is used to power the power consumer 2. When the power required by the power consumer 2 is met, the remaining power from the thermoelectric power generation structure 20 is used to charge the battery 7. When the power generated by the thermoelectric power generation structure 20 is less than the power required by the power consumer, the battery 7 is used to power the power consumer, and the power generated by the thermoelectric power generation structure 20 is used to charge the battery 7. When the remaining power of the battery 7 is greater than a preset power threshold, the power generated by the thermoelectric power generation structure 20 is not used to charge the battery 7. The circuit structure of the power management circuit 6 is conventional and is not improved in this embodiment.

[0072] The battery 7 is a rechargeable battery used to store the electrical energy generated by the thermoelectric power generation structure 20 or to supply power to the electrical device 2 .

[0073] The processor 9 is used to determine the working mode of the power management circuit 6 based on the required power of the electrical equipment, the power generated by the thermoelectric power generation structure 20 and the remaining power of the battery 7.

[0074] The wireless communication unit 8 includes a wireless communication circuit and an antenna, and can adopt 4G, 5G and other modes to send information such as the power generated by the power supply, battery 7, thermoelectric power generation structure 20 and the status of the electrical equipment 2 to the server for user use.

[0075] The heat / cold source pipe 1 transfers the heat or cold of the fluid from the clamping structure 60 to the connecting part 11. The heat of the connecting part 11 is transferred to the heat conducting part 12 through the through hole 13. The heat conducting part 12 transfers the heat or cold of the fluid in the through hole 13 to the thermoelectric power generation structure 20 and the heat dissipation structure 30. The heat dissipation structure 30 transfers the heat or cold of the fluid to the external environment medium to form a temperature difference at both ends of the thermoelectric power generation structure 20, so that the conductive layer 22 of the thermoelectric power generation structure 20 generates electrical energy, and the electrical energy generated by the conductive layer 22 is input into the electrical equipment 2.

[0076] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These modifications and improvements will not affect the effect of the implementation of the present invention and the practicality of the patent.
