Description
Technical Field
[0001] The present invention belongs to the technical field of wind energy collection and measurement devices, and in particular relates to an adaptive wind energy collection and power supply device based on pipeline monitoring. Background Art
[0002] Pipeline monitoring refers to the technology of real-time or regular detection and evaluation of the operating status of various pipeline fluids (such as flow rate, temperature, pressure and other parameters) to ensure the safe operation of pipelines, prevent accidents and improve maintenance efficiency.
[0003] In the prior art, the monitoring units installed on the pipeline involve a series of sensors, and each sensor requires continuous power supply. However, when it comes to pipeline monitoring in remote areas, the power supply method usually adopts the installation of independent batteries, photovoltaic power generation, and the establishment of independent wind power generation. However, the battery-powered mode requires manual regular replacement of batteries, which is time-consuming and labor-intensive. Photovoltaic power generation requires regular maintenance, and over time, dust and debris will cause the power generation to decrease; therefore, wind power generation is relatively speaking the best choice for pipeline monitoring in remote areas. Independently installed wind turbines can cover multiple monitoring units at the same time. However, wind power generation requires independent wind turbines, which not only require wiring and regular maintenance, but also require a large installation space, high installation costs, and when the wind is weak, the wind turbine cannot rotate to generate electricity, poor adaptability, and poor practicality.

[0019] Please also refer to Figures 1 to 6 The adaptive wind energy harvesting and power supply device based on pipeline monitoring provided by the present invention will now be described. The adaptive wind energy harvesting and power supply device based on pipeline monitoring includes a connecting base 10, a rotating shaft 20, a rotor 30, a first power generation module 40, and a second power generation module 50. The connecting base 10 is mounted on a fluid pipeline. The connecting base 10 has a connecting cavity. The rotating shaft 20 is rotatably mounted on the connecting base 10, with one end of the rotating shaft 20 extending from the connecting base 10 and connected to a wind cup or fan blade. The rotor 30 is located in the connecting cavity and coaxially fixedly connected to the rotating shaft 20. The rotor 30 has a first magnetic portion and a second magnetic portion that can move outward under centrifugal force when the rotor 30 rotates. The first power generation module 40 is located in the connecting cavity and is provided with a first coil 41 corresponding to the first magnetic portion. The second power generation module 50 is located in the connecting cavity and has multiple second power generation portions arranged around the rotor 30. Each second power generation portion is configured to generate a concave-convex change and generate electricity when it corresponds to the outward-moving second magnetic portion.
[0020] When the wind is weak, the shaft 20 drives the rotor 30 to rotate, causing the first magnetic portion to interact with the first coil 41 of the first power generation module 40 to generate electricity. When the wind is strong, the shaft 20 drives the rotor 30 to rotate, causing the first magnetic portion to interact with the first coil 41 of the first power generation module 40 to generate electricity, while also causing the second magnetic portion to interact with the second power generation portion of the second power generation module 50 to generate electricity.
[0021] Compared with the prior art, the adaptive wind energy collection and power supply device based on pipeline monitoring provided in this embodiment realizes an integrated design of the device and the pipeline by providing a connection base 10 installed on the fluid pipeline, eliminating the need for an additional large installation space and reducing the installation cost. The wind cup or fan blade is used to drive the rotating shaft 20 to rotate, converting wind energy into mechanical energy to provide power for power generation. The device can automatically adjust the power generation mode according to the wind force. When the wind force is small, power is generated only through the interaction between the first magnetic part and the first coil 41 of the first power generation module 40, ensuring power generation efficiency at low wind speeds. When the wind force is strong, the second magnetic part moves outward under the action of centrifugal force and interacts with the second power generation part of the second power generation module 50 to generate power, increasing the power generation power and improving the utilization efficiency of wind energy. This allows the device to provide stable power supply under different wind conditions, and has good adaptability and practicality.
[0022] The adaptive wind energy collection and power supply device based on pipeline monitoring also includes a battery, which can store the electricity converted by wind energy collection and supply the electricity to the detection unit.
[0023] In some embodiments, the first power generation module 40 may be configured as follows: Figure 2 、 Figure 3 、 Figure 4 The structure shown. Figure 2 、 Figure 3 、 Figure 4 There are two first power generation modules 40, which are arranged on both sides of the rotor 30 along the vertical direction of the first power generation module 40. Each first power generation module 40 includes a fixed disk 42, and the axis of the fixed disk 42 is arranged collinearly with the axis of the rotating shaft 20.
[0024] Each fixed disk 42 is provided with a plurality of first coils 41 , and the first coils 41 are arranged in a ring-shaped manner around the axis of the rotating shaft 20 .
[0025] Two first power generation modules 40 are arranged on both sides of the rotor 30 in the vertical direction, which can make full use of the rotational energy of the rotor 30. The multiple first coils 41 arranged at annular intervals on each fixed disk 42 cooperate with the first magnetic part on the rotor 30 to form an efficient power generation structure. This symmetrical arrangement allows the first power generation modules 40 on both sides of the rotor 30 to generate electricity simultaneously during the rotation of the rotor 30, thereby improving the power generation efficiency. Moreover, the axis of the fixed disk 42 and the axis of the rotating shaft 20 arranged in a collinear manner ensure that the relative position of the rotor 30 and the first coil 41 is stable during rotation, reducing energy loss and further improving the power generation effect. By increasing the number of first power generation modules 40 and reasonably arranging the first coils 41, the above structure can generate more electricity under the same wind energy input, providing more reliable power support for the pipeline monitoring unit.
[0026] The number of first power generation modules 40 can be adjusted according to actual needs, for example, three or more power generation modules can be provided to further improve power generation efficiency. The arrangement of the first coils 41 on the fixed disk 42 can also be changed to a spiral or other irregular shape to optimize the magnetic field distribution and increase the induced electromotive force.
[0027] In some embodiments, the rotor 30 may be configured as follows: Figure 3 、 Figure 4 The structure shown. Figure 3 、 Figure 4 The rotor 30 includes a magnet disk 31 and a centrifugal cutting structure 32. Two magnet disks 31 are provided, spaced vertically between two fixed disks 42. Each magnet disk 31 is coaxially sleeved on the rotating shaft 20. Each magnet disk 31 is provided with a plurality of first magnets 311 annularly spaced along the rotation axis of the magnet disk 31. The first magnets 311 collectively constitute a first magnetic portion. The centrifugal cutting structure 32 is provided between the two magnet disks 31 and is provided with a plurality of centrifugal cutting portions. When the rotating shaft 20 rotates at a high speed, each centrifugal cutting portion drives the centrifugal cutting portion to move outward in the radial direction of the rotating shaft 20.
[0028] The magnetic poles of the first magnets 311 on the magnet disks 31 are staggered.
[0029] The first magnets 311 on the two magnet disks 31 are arranged in a one-to-one correspondence, and the magnetic poles of the two first magnets 311 spaced apart in the vertical direction attract each other.
[0030] The structural design of the rotor 30 has many advantages. The poles of the first magnets 311 on the two magnet disks 31 are staggered, and the poles of the two first magnets 311 spaced apart in the vertical direction attract each other. This design can form a stronger magnetic field. When the rotor 30 rotates, the changing magnetic field interacts with the first coil 41 to generate a larger induced electromotive force, thereby improving the power generation efficiency. The setting of the centrifugal cutting structure 32 makes it possible to generate additional power when the wind is strong. When the speed increases, the centrifugal cutting part moves radially outward, triggering the second power generation module 50 to work, and realizing adaptive switching of the power generation mode. This layered power generation structure enables the device to flexibly adjust the power generation strategy according to the wind force, while ensuring stable power generation at low wind speeds, making full use of the energy at high wind speeds, thereby improving the energy conversion efficiency and adaptability of the entire device.
[0031] The first magnets 311 on the magnet disk 31 can be made of different materials or shapes, such as neodymium iron boron magnets or arc magnets, to enhance the magnetic field strength.
[0032] In some embodiments, the centrifugal cutting structure 32 may be formed as follows: Figure 3 、 Figure 4 The structure shown. Figure 3 、 Figure 4 The centrifugal cutting structure 32 includes a rotating frame 321, a sliding rod 322, a spring 323 and a second magnet 324. The rotating frame 321 is coaxially sleeved on the rotating shaft 20 and is located between the two magnet disks 31. The rotating frame 321 rotates synchronously with the rotating shaft 20. The rotating frame 321 is provided with a plurality of extension rods, each of which is arranged in a ring-shaped interval along the rotation axis of the rotating frame 321. One end of each extension rod is fixed on the rotating frame 321, and the other end extends horizontally outward. A limit block is provided on the extended end of each extension rod. There are multiple sliding rods 322, each sliding rod 322 is correspondingly arranged with each limit block. One end of each sliding rod 322 is slidably set on the limit block along the extension direction of the extension rod, and the other end of each sliding rod 322 extends outward. A limit plate is provided on the sliding end of each sliding rod 322, and a connecting block is provided on the extended end of each sliding rod 322. There are multiple springs 323, each corresponding to a sliding rod 322. Each spring 323 is sleeved onto the corresponding sliding rod 322. One end of each spring 323 abuts the limit plate, and the other end abuts the limit block. Each spring 323 is used to ensure that the corresponding sliding rod 322 always has a tendency to move toward the rotating frame 321. There are multiple second magnets 324, each corresponding to a connecting block. Each second magnet 324 is a centrifugally cut portion and together constitutes the second magnetic portion.
[0033] The magnetic poles of the second magnets 324 are arranged at staggered intervals.
[0034] A plurality of auxiliary coils are provided on the side wall of the connection base 10 , and the auxiliary coils are arranged at intervals along the axis of the rotating shaft 20 .
[0035] The setting of the spring 323 makes the sliding rod 322 always have a tendency to move toward the rotating frame 321. When the wind speed is low, the second magnet 324 is in the initial position and does not participate in power generation. When the wind speed increases and the centrifugal force overcomes the force of the spring 323, the second magnet 324 moves outward and cooperates with the second power generation module 50 to generate electricity. This design realizes the automatic switching of the power generation mode without the need for external control, thereby improving the reliability and stability of the device. The staggered setting of the magnetic poles of each second magnet 324 and the auxiliary coils on the side walls of the connection base 10 further enhance the power generation effect. The auxiliary coils can capture the stray magnetic field generated during the rotation of the rotor 30 and convert it into electrical energy, thereby improving the energy utilization rate. The design of the entire centrifugal cutting structure 32 is ingenious, and adaptive adjustment of the power generation mode is achieved through mechanical centrifugal force.
[0036] The position and number of the auxiliary coils can also be adjusted according to actual conditions, for example, by increasing the number of auxiliary coils or changing their distribution to improve the ability to capture stray magnetic fields.
[0037] In some embodiments, the second power generation module 50 may be configured as follows: Figure 3 、 Figure 4 The structure shown. Figure 3 、 Figure 4 The second power generation module 50 includes a sudden jump beam 51 and a third magnet 52. There are multiple sudden jump beams 51, each of which is arranged in a ring-shaped manner along the axis of the rotating shaft 20 in the connecting cavity. Each sudden jump beam 51 is arranged horizontally, and both ends of each sudden jump beam 51 are fixed to the inner wall surface of the connecting base 10. The middle section of each sudden jump beam 51 has two stable states, and each sudden jump beam 51 switches between the two stable states when each second magnet 324 rotates past. There are multiple third magnets 52, each third magnet 52 is arranged corresponding to each sudden jump beam 51, and each third magnet 52 is arranged on the corresponding sudden jump beam 51.
[0038] The magnetic poles of each third magnet 52 on each jump beam 51 are staggered.
[0039] The middle section of the sudden jump beam 51 has two stable states. When the second magnet 324 rotates past, the magnetic force causes the sudden jump beam 51 to switch quickly between the two stable states, resulting in concave and convex changes. During this mechanical deformation process, the relative position of the third magnet 52 and the surrounding magnetic field changes, thereby generating an induced current in the coil. The poles of each third magnet 52 on the sudden jump beam 51 are staggered, which further enhances the amplitude of the magnetic field change and improves the power generation efficiency. This bistable characteristic of the sudden jump beam 51 makes the power generation process have intermittent pulse characteristics, which can generate a large current in a relatively short time, and is suitable for charging energy storage equipment or powering monitoring units with a high tolerance for current fluctuations. This power generation method complements the first power generation module 40, so that the device can generate electricity efficiently under different wind speed conditions.
[0040] The snap beam 51 can be made of various materials or structures, such as a bistable beam made of a shape memory alloy or composite material. High-elasticity hardened manganese steel is generally suitable for bistable beams. The arrangement of the third magnet 52 can also be modified, for example, by using an electromagnetic coil instead of a permanent magnet, and adjusting the magnetic field strength and direction by controlling the current.
[0041] In some embodiments, the sudden jump beam 51 can be used as follows Figure 3 、 Figure 4 The structure shown. Figure 3 、 Figure 4 A copper electrode is provided on one side of each sudden jump beam 51 close to the inner wall of the connection base 10, an electron receiving electrode is provided on the inner wall of the connection base 10, and a piezoelectric sheet is provided on the two connecting ends of each sudden jump beam 51.
[0042] When the snap beam 51 undergoes a concave change, the copper electrode and the receiving electrode suddenly contact, and electrons are transferred from the surface of the copper electrode to the surface of the receiving electrode. The copper electrode is positively charged, and the receiving electrode is negatively charged. When the snap beam 51 undergoes a convex change, the two charged surfaces are forced to suddenly separate, creating a potential difference between the two sensing electrodes. Electrons flow from one electrode to the other through an external resistor, generating a current in the circuit. As the magnet disk rotates, the snap beam periodically snaps into and out of contact, and charge moves between the sensing electrodes through an external load, producing a continuous AC output. This structure can extract more electrical energy from the same mechanical motion, enhancing the device's energy harvesting capabilities.
[0043] The materials used for the electron-earthing electrode (FEP film) and the electron-losing electrode (copper film) are chosen to have a significant difference in polarity between the electron-earthing and electron-losing electrodes. This allows for electrostatic induction and triboelectric effects, improving conductivity and energy conversion efficiency. The piezoelectric sheet can also be replaced with other piezoelectric materials or mounted in a different manner, such as a multilayer stack, to enhance the piezoelectric effect.
[0044] In some embodiments, the above-mentioned adaptive wind energy collection and power supply device based on pipeline monitoring can be used as follows: Figure 1 、 Figure 5 The structure shown. Figure 1 、 Figure 5 The adaptive wind energy harvesting and power supply device based on pipeline monitoring also includes an auxiliary power generation structure 60, which is disposed above the connection base 10. The auxiliary power generation structure 60 comprises an auxiliary cover 61, a fourth magnet 62, a positioning and limiting assembly 63, a cantilever beam 64, and a fifth magnet 65. The auxiliary cover 61 has an auxiliary cavity with an open bottom end. The auxiliary cover 61 snaps onto the top of the connection base 10 and is rotatably connected to the rotating shaft 20. A plurality of fourth magnets 62 are provided, each annularly spaced along the axis of the rotating shaft 20 and disposed on the top of the auxiliary cover 61. A plurality of positioning and limiting assemblies 63 are provided, each corresponding to a fourth magnet 62. Each positioning and limiting assembly 63 comprises two curved plates 631, one end of each of which is fixed to the auxiliary cover 61 and connected to each other. The other end of each curved plate 631 extends into the auxiliary cavity. The extended ends of the two corresponding curved plates 631 are open, forming a V-shaped cavity. Multiple cantilever beams 64 are provided, each corresponding to a positioning and limiting assembly 63. Each cantilever beam 64 is disposed within a corresponding V-shaped cavity. One end of each cantilever beam 64 is connected to the connection end of the curved plate 631, and the other end of each cantilever beam 64 extends outward. Each cantilever beam 64 is configured to swing horizontally with the rotation of the magnet disk 31. Multiple fifth magnets 65 are provided, each corresponding to a cantilever beam 64 and fixed to the extended end of the corresponding cantilever beam 64.
[0045] The magnetic poles of the fourth magnets 62 are arranged in the same direction.
[0046] The magnetic poles of the fifth magnets 65 are arranged in the same direction, and the magnetic poles of the fifth magnets 65 and the corresponding fourth magnets 62 are arranged in a repulsive direction.
[0047] When the magnet disk 31 on the rotor 30 rotates, the fifth magnet 65 swings with the cantilever beam 64, and the repulsive force between the fifth magnet 65 and the fourth magnet 62 causes the cantilever beam 64 to reciprocate in the V-shaped cavity. During this movement, the magnetic field between the fifth magnet 65 and the fourth magnet 62 changes, which may generate an induced current in the coil. The V-shaped cavity structure of the positioning limit assembly 63 limits and guides the swing of the cantilever beam 64, ensuring the stability and regularity of the movement. The magnetic pole direction setting of each fourth magnet 62 and the fifth magnet 65 ensures the consistency of the repulsive force, so that the cantilever beam 64 can swing as expected. The design of the auxiliary power generation structure 60 cleverly utilizes the indirect energy generated by the rotation of the rotor 30 and converts it into electrical energy, further improving the energy utilization efficiency of the entire device. In particular, when the wind is relatively weak, the auxiliary power generation structure 60 can provide additional power support, enhancing the adaptability of the device.
[0048] The structures of cantilever beam 64 and positioning and limiting assembly 63 can be simplified or improved, for example, by replacing the V-shaped cavity with an elastic support structure to reduce friction losses. The fourth and fifth magnets 62 and 65 can also be replaced by electromagnetic coils, allowing for more flexible power generation control by adjusting the magnetic field strength and direction through current control.
[0049] In some embodiments, the cantilever beam 64 may be formed as follows: Figure 5 The structure shown. Figure 5 Copper electrodes are provided on the two sidewall surfaces of each cantilever beam 64, and electron-generating electrodes are provided on the sidewall surfaces of the V-shaped cavity formed by each arc plate 631.
[0050] Copper electrodes are provided on the two side walls of the cantilever beam 64, and electron-beam electrodes are provided on the side walls of the V-shaped cavity formed by the arc plate 631, utilizing the principle of frictional power generation. When the cantilever beam 64 swings in the V-shaped cavity, friction or relative motion occurs between the copper electrode and the electron-beam electrode, resulting in the transfer of electrostatic charge, thereby realizing the conversion of mechanical energy into electrical energy. This frictional power generation method has the advantages of simple structure and low cost, and can generate electrical energy during the slight swing of the cantilever beam 64. Combined with other power generation methods, the efficiency of the auxiliary power generation structure 60 is further improved. By providing power generation electrodes on both side walls of the cantilever beam 64, full use is made of the bidirectional swing of the cantilever beam 64, and the power generation opportunities are increased, so that the auxiliary power generation structure 60 can collect energy more effectively and provide a continuous and stable power supply for the pipeline monitoring unit.
[0051] The copper electrode and the electron-acquiring electrode can be made of other triboelectric materials, such as polytetrafluoroethylene and nylon, to improve triboelectric efficiency. The power generation structure can also be changed to a contact-separation or sliding triboelectric unit to adapt to different motion modes and power generation needs.
[0052] Based on the same inventive concept, an embodiment of the present invention further provides a detection pipeline 70, which includes a connecting pipeline 71, an adaptive wind energy collection and measurement device for pipeline monitoring, an impeller 72, and a guide plate 73. The connecting pipeline 71 is connected to the pipeline to be tested at both ends, and a connecting platform is provided on the connecting pipeline 71. The connecting pipeline 71 has a through detection cavity. The adaptive wind energy collection and measurement device for pipeline monitoring is provided on the connecting platform. The impeller 72 is provided in the detection cavity and is connected to a connecting shaft. The guide plate 73 is provided in the detection cavity and is used to guide the fluid passing through the detection cavity to one side of the impeller 72.
[0053] A one-way bearing is provided at the rotation connection between the rotating shaft 20 and the connection base 10 and the auxiliary cover 61 .
[0054] When wind speed is low, the cups or blades drive the shaft 20, which in turn rotates the rotor 30. At this point, the centrifugal force is low, and the second magnetic portion (second magnet 324) remains in its initial position under the action of the spring 323, out of contact with the second power generation portion of the second power generation module 50. The first magnetic portion (first magnet 311) on the rotor 30 rotates with the rotor 30, interacting with the first coil 41 of the first power generation module 40. This generates an induced current based on the principle of electromagnetic induction, thus achieving power generation. At this point, the device primarily generates electricity through the first power generation module 40, providing power to the pipeline monitoring unit.
[0055] As wind speed increases, the rotational speed of the rotating shaft 20 increases, increasing the centrifugal force. When the centrifugal force becomes greater than the elastic force of the spring 323, the second magnetic portion (second magnet 324) moves radially outward, approaching the second power generation section of the second power generation module 50. Under the magnetic force of the second magnet 324, the snap beam 51 in the second power generation section rapidly switches between two stable states, producing a concave-convex change. This mechanical deformation changes the relative position of the third magnet 52 with the surrounding magnetic field, generating an induced current in the coil. Simultaneously, electrostatic induction or triboelectric charging may occur between the copper electrode on the snap beam 51 and the receiving electrode on the inner wall of the connection base 10. The piezoelectric element at the connection end of the snap beam 51 also generates a piezoelectric effect due to deformation, all of which convert mechanical energy into electrical energy. At this point, the device generates electricity simultaneously through the first power generation module 40 and the second power generation module 50, significantly increasing the generated power to meet the power needs of the pipeline monitoring unit during strong winds.
[0056] Furthermore, the auxiliary power generation structure 60 is also operating throughout this process. As the magnet disk 31 on the rotor 30 rotates, it drives the fifth magnet 65 to swing along with the cantilever beam 64. The repulsive force between the fifth magnet 65 and the fourth magnet 62 causes the cantilever beam 64 to reciprocate within the V-shaped cavity. Friction or relative motion between the copper electrodes on the sidewalls of the cantilever beam 64 and the electron-receiving electrodes on the curved plate 631 generates electrostatic charge transfer, converting mechanical energy into electrical energy. The auxiliary power generation structure 60 provides additional power output for the device, further improving energy efficiency.
[0057] When the wind speed decreases, the centrifugal force decreases, and the second magnetic portion returns to its initial position under the action of spring 323. The second power generation module 50 stops operating, and the device once again generates electricity only through the first power generation module 40, returning to low wind speed operation. Through this adaptive method, the entire device automatically adjusts its power generation strategy according to wind speed, achieving efficient collection and utilization of wind energy and providing a stable and reliable power supply for the pipeline monitoring unit.
[0058] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
