[0045] Secondly, when installing the protection assembly 5, place the lower protection cover 504 on the support rod 502, align the mounting holes on the lower protection cover 504 with the bolts 503 on the support rod 502, then cover the upper protection cover 505 on the lower protection cover 504, and also align the mounting holes of the upper protection cover 505 with the bolts 503; put the washers on the bolts 503, then tighten the nuts to fix the lower protection cover 504 and the upper protection cover 505 on the support rod 502; during the installation process, ensure that the semi-coupling 203 tightly abuts against the sealing sleeve 508 on the protection cover, and check whether the maintenance plate 507 is accurately inserted into the slot 515 and tightly abuts against the sealing strip 509; when it is necessary to maintain and replace the internal components through the maintenance window 506, pull the pull block 514 on the upper protection cover 505, pull the pull block 514 upward, and the pull block 514 drives the pull rod 511 to slide upward along the fixed sleeve 510, at this time the fourth spring 513 is compressed, continuously pull the pull rod 511 until the lower end of the pull rod 511 completely separates from the limiting hole 512 on the maintenance plate 507, and the fixing of the maintenance plate 507 is released, slide the maintenance plate 507 outward along the horizontal direction with the other hand, so that the maintenance plate 507 gradually separates from the slot 515 on the upper protection cover 505, after pulling the maintenance plate 507 to the appropriate position, the other pull rod 511 is clamped into the limiting hole 512 under the elastic force of the fourth spring 513, at this time the maintenance window 506 is completely exposed, which is convenient for maintaining and replacing the components wrapped in the upper protection cover 505 and the lower protection cover 504, and the maintenance plate 507 continuously presses the micro switch 516 to make it in the “closed” state, at this time the equipment control system recognizes as “non-maintenance state”, allowing the load machine 7 and the shaft generator body 8 to normally start and run, when opening the maintenance, it is necessary to slide the maintenance plate 507 outward to open the maintenance window 506, the maintenance plate 507 separates from the abutment with the micro switch 516, and the micro switch 516 is reset to the “open” state, the state signal is transmitted to the equipment control system, and the starting circuit of the load machine 7 and the shaft generator body 8 is forcibly cut off, even if the start button is mistakenly touched, the equipment cannot run, which fundamentally avoids the safety accidents of the maintenance personnel being rolled in when contacting the internal transmission parts (such as the semi-coupling 203 and the plum blossom elastic body 207);

[0046] Finally, during the operation of the device, the plum blossom elastic body 207 will be elastically deformed, and during the deformation process, it will exert pressure on the wear-resistant gasket 604, and the pressure is transmitted to the piezoelectric ceramic sheet 603, so that the piezoelectric ceramic sheet 603 generates a piezoelectric effect, converts mechanical energy into electrical energy, and the electrical energy generated by the piezoelectric ceramic sheet 603 is transmitted to the PCB board 607 in the mounting box 605 through the wire through the wire hole 606. The PCB board 607 rectifies and stabilizes the electrical energy, and then stores it in the lithium battery 608. When the electrical energy stored in the lithium battery 608 is needed, the lithium battery 608 can be connected with auxiliary power equipment (such as indicator lights, sensors, etc.) of the device through the output interface on the mounting box 605 to supply power for it, realize the recycling of energy, and reduce the overall energy consumption of the device.
