Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0031] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0032] Example 1

[0033] Reference Figure 1-Figure 2 , provides an overall structural schematic diagram of an energy harvester structure based on low-frequency vibration of an iron tower, an energy harvester structure based on low-frequency vibration of an iron tower includes a structural component 100, including a vibration displacement amplifier 101 and a vibration energy harvester 102, the vibration displacement amplifier 101 is a support for the entire device, the vibration energy harvester 102 is arranged on the upper side of the vibration displacement amplifier 101, a cleaning component 200, including an adjusting component 201, a moving component 202 and a cleaning component 203, the adjusting component 201 is arranged on both sides of the vibration displacement amplifier 101, the moving component 202 is arranged on the side of the adjusting component 201, and the cleaning component 203 is arranged on the side of the moving component 202, a cutting component 300, including a lifting component 301 arranged on the upper side of the adjusting component 201, an extruding component 302 arranged in the cleaning component 203 and a collecting component 303 arranged on the upper side of the vibration displacement amplifier 101.

[0034] Specifically, the vibration displacement amplifier 101 includes a base 101a, a bottom plate spring 101b arranged above the base 101a, and a mounting frame 101c arranged above the bottom plate spring 101b. Four bottom plate springs 101b are provided and distributed above the base 101a. The two ends of the bottom plate spring 101b are respectively in contact with the upper surface of the base 101a and the lower surface of the mounting frame 101c. The vibration displacement amplifier 101 also includes a mounting plate 101d arranged above the mounting frame 101c, a guide rail 101e arranged on one side of the mounting plate 101d, a metal roller 101f rollingly arranged above the guide rail 101e, and a buffer spring 101g sleeved on the outside of the guide rail 101e.

[0035] Furthermore, the vibration energy harvesting component 102 includes a cantilever beam 102a disposed in the mounting frame 101c, a magnet 102b disposed above the cantilever arm, and a piezoelectric piece 102c disposed at the end of the cantilever arm.

[0036] The vibration energy harvester 102 works on the principle of vibration power generation. After the energy harvester is installed, under vibration excitation, the bottom plate spring 101b first senses the external excitation and vibrates, starting to amplify the vibration displacement. After the device deflects, the metal roller 101f begins to roll, and the magnet 102b at the end of the piezoelectric cantilever beam 102a below is attracted and deforms significantly. After the metal roller 101f rolls over, the piezoelectric cantilever beam 102a naturally falls and vibrates freely. The piezoelectric plate 102c attached to the end of the piezoelectric cantilever beam 102a undergoes mechanical deformation, generating electrical energy. When the metal roller 101f is about to hit the mounting plate 101d, the spring of the mounting plate 101d will act as a buffer and utilize the impact energy. After the spring of the mounting plate 101d is released, it pushes the metal roller 101f to perform the next energy harvesting. Throughout the entire process, there is always a beam in the distributed piezoelectric cantilever beam 102a group that vibrates to harvest energy, realizing energy harvesting throughout the process and ensuring efficient energy utilization.

[0037] Operation process: After the device is installed at the tower installation location, the vibration of the tower is transmitted to the base spring 101b. The base spring 101b vibrates after sensing external excitation and begins to amplify the vibration displacement. After the device is deflected, the metal roller 101f begins to roll, and the magnet 102b at the end of the piezoelectric cantilever beam 102a below is attracted and deforms greatly. When the metal roller 101f rolls over, the piezoelectric cantilever beam 102a naturally falls and vibrates freely. The piezoelectric piece 102c attached to the end of the piezoelectric cantilever beam 102a undergoes mechanical deformation to generate electrical energy. When the metal roller 101f is about to hit the mounting plate 101d, the buffer spring 101g will play a buffering role and utilize the impact energy. After the buffer spring 101g is released, it pushes the metal roller 101f to extract energy next time.

[0038] Example 2

[0039] Reference Figure 2-Figure 7 This embodiment is different from the first embodiment in that: the adjusting member 201 includes a mounting frame 201a arranged on both sides of the mounting frame 101c and a groove 201b opened above the mounting frame 201a, the adjusting member 201 also includes a screw rod 201c threadedly arranged on the lower side of the mounting frame 201a and a lifting plate 201d slidably arranged in the mounting frame 201a, the screw rod 201c extends into the mounting frame 201a and is threadedly connected thereto, and one end of the screw rod 201c extending into the mounting frame 201a is rotatably connected to the lifting plate 201d. Through this arrangement, the screw 201c can be rotated when necessary to drive the lifting plate 201d to move it up and down for adjustment.

[0040] Specifically, the moving part 202 includes a sliding block 202a slidably arranged on the upper side of the lifting plate 201d, a mounting block 202b arranged above the sliding block 202a, and a card slot 202c opened above the mounting block 202b. The moving part 202 also includes a connecting rod 202d arranged on one side of the metal roller 101f and a card rod 202e arranged on one side of the connecting rod 202d. One end of the connecting rod 202d extends into the card rod 202e and is hinged to the card rod 202e, and one end of the card rod 202e extends into the card slot 202c and is slidably connected to the card rod. Through this arrangement, when the screw 201c can be rotated to drive the lifting plate 201d to move upward, the card rod 202e is inserted into the card slot 202c and is snap-fixed, so that the metal roller 101f drives the sliding block 202a to slide left and right when it rotates.

[0041] Furthermore, the cleaning part 203 includes a placement block 203a arranged on one side of the mounting block 202b and a placement groove 203b opened on the lower surface of the placement block 203a. A sticky tape is placed in the placement groove 203b. The set sticky tape can be used to magnetically levitate and remove iron filings and the like on the upper surface of the magnet 102b when in contact with the magnet 102b. At the same time, the sticky tape is stacked layer by layer in the placement block 203a, and a protective film will be adhered to the sticky surface of the sticky tape to protect the tape when not in use.

[0042] The lifting member 301 includes a threaded rod 301a rotatably arranged on the inner wall of the installation frame 201a, a gear 301b sleeved on the outer surface of the threaded rod 301a, and a tooth block 301c arranged on one side of the sliding block 202a, the tooth block 301c is meshed with the gear 301b, the lifting member 301 also includes a lifting block 301d threadedly arranged on the outer surface of the threaded rod 301a and a cutting knife 301e arranged on the upper side of the lifting block 301d, the upper surface of the installation frame 201a is provided with a notch matched with the lifting block 301d, the screw 201c is threadedly connected to the lifting block 301d. When the screw 201c rotates, the lifting block 301d is driven to move up and down. In this way, when the moving block moves left and right, the tooth block 301c engages with the gear 301b, driving the gear 301b to rotate, thereby driving the screw 201c to rotate and raising the cutting knife 301e. After the cutting knife 301e is raised, its height is just enough to cut off the bottom layer of sticky tape placed in the placement block 203a, thereby cutting the layer of tape that is adhered to the iron filings.

[0043] The rest of the structure is the same as that of Example 1.

[0044] Operation process: When the cleaning component 200 is not in use, the placement block 203a is located on one side above the mounting frame 101c, which will not affect the vibration energy extraction of the cantilever beam 102a. When the magnetic block needs to be cleaned, first tear off the protective film on the sticky surface of the tape, then rotate the screw 201c to drive the lifting plate 201d to move upward, thereby driving the sliding block 202a and the mounting block 202b to move upward, so that the clamping rods 202e set on both sides of the metal roller 101f are inserted into the clamping groove 202c opened above the mounting block 202b. According to the vibration energy extraction, the metal roller 101f rolls to drive the sliding block 202a and the mounting block 202b to slide left and right. At this time, the sticky surface of the tape will contact the upper surface of the magnet 102b. When sliding left and right, the iron filings and the like on the upper surface of the magnet 102b are adsorbed and cleaned. At the same time, when the sliding block 202a slides to the other side for the first time, the tooth block 301c is used to drive the gear 301b to rotate, thereby driving the threaded rod 301a to rotate forward, and then the cutting knife 301e is raised. During the return process, the cutting knife 301e is in a raised state and will cut the sticky tape with the iron filings attached. Then the tooth block 301c will drive the gear 301b to rotate in the opposite direction, thereby driving the threaded rod 301a to rotate in the opposite direction and lowering the cutting knife 301e. Finally, after the device returns to the initial position, the screw rod 201c is rotated in the opposite direction to lower the entire device and continue the vibration energy extraction process.

[0045] Example 3

[0046] Reference Figure 4-Figure 8, this embodiment is different from the above embodiment in that: the lifting member 301 includes a threaded rod 301a rotatably set on the inner wall of the installation frame 201a, a gear 301b sleeved on the outer surface of the threaded rod 301a, and a tooth block 301c set on one side of the sliding block 202a, the tooth block 301c is meshed with the gear 301b, the lifting member 301 also includes a lifting block 301d threadedly set on the outer surface of the threaded rod 301a and a cutting knife 301e set on the upper side of the lifting block 301d, and the upper surface of the installation frame 201a is provided with a gear 301b that matches the lifting block 301d. The screw 201c is threadedly connected to the lifting block 301d through a slot provided. When the screw 201c rotates, the lifting block 301d is driven to move up and down. By this, when the moving block moves left and right, the tooth block 301c engages with the gear 301b, driving the gear 301b to rotate, thereby driving the screw 201c to rotate and raise the cutting knife 301e. After the cutting knife 301e is raised, its height is just enough to cut off the bottom layer of sticky tape placed in the placement block 203a, thereby cutting the layer of tape that is adhered to the iron filings.

[0047] Furthermore, the extrusion member 302 includes a compression spring 302a and a pressure plate 302b arranged in the placement block 203a, and the two ends of the compression spring 302a are respectively connected to the side wall of the pressure plate 302b and the inner wall of the placement block 203a. Through the arrangement of the compression spring 302a and the pressure plate 302b, the penultimate layer of the adhesive tape can be pressed to the bottom layer after the bottom layer of the adhesive tape is cut, so that it can contact the magnet 102b.

[0048] Specifically, the collecting member 303 includes a through slot 303a opened above the mounting frame 101c and an inclined plate 303b arranged in the through slot 303a. The through slot 303a and the cutting knife 301e are at the same horizontal position. The cut adhesive tape can be collected and processed through the set through slot 303a and inclined plate 303b.

[0049] The rest of the structure is the same as that of Example 2.

[0050] Operation process: Before use, stack the sticky tape layer by layer and place it in the placement block 203a. The vibration energy is obtained by the metal roller 101f rolling to drive the sliding block 202a and the mounting block 202b to slide left and right. At this time, the sticky surface of the tape will contact the upper surface of the magnet 102b. When sliding left and right, the iron filings on the upper surface of the magnet 102b are adsorbed and cleaned. At the same time, when the sliding block 202a slides to the other side for the first time, the tooth block 301c provided will drive the gear 301b to rotate, thereby driving the threaded rod 301a to rotate in the forward direction, and then the cutting knife 301e is raised. During the return process, the cutting knife 301e is in a raised state, which will remove the sticky tape adhering to the iron filings. The tape is cut, and then the tooth block 301c drives the gear 301b to rotate in the opposite direction, thereby driving the threaded rod 301a to rotate in the opposite direction, lowering the cutting knife 301e. Finally, after the device returns to the initial position, the screw rod 201c is rotated in the opposite direction to lower the device as a whole. At the same time, after the cutting knife 301e cuts the sticky tape, the sticky tape falls onto the inclined plate 303b in the through groove 303a and is directly collected and processed quickly. At the same time, the compression spring 302a and the pressure plate 302b can be set to press the second-to-last layer of sticky tape to the bottom layer after cutting the bottom layer of sticky tape, so that it can contact the magnet 102b, and so on, until all the sticky tapes are used up.
