The power generation main shaft 31 and the rotating shaft of the generator 5 are connected together by a flexible transmission mechanism 6. In this way, when the driving unit 4 drives the power generation slide 3 to move, the flexible deformation of the flexible transmission mechanism 6 makes the rotating shaft of the generator 5 always connected with the power generation main shaft 31, so that the generator 5 can be independently installed on the power generation base 2 without moving synchronously with the power generation slide 3, thereby enhancing the stability of the use of the generator 5 and the power output cable of the generator 5, so that the generator 5 can stably provide power to the new energy power supply system and ensure the energy-saving effect of the elevator.

[0031] In this embodiment, the new energy power supply system includes a photovoltaic power supply device 801, a power switching circuit system, a mains, a power supply output controller, a first storage battery and a second storage battery; the power switching circuit system includes a first power switching switch, a second power switching switch and a third power switching switch connected and controlled by the power supply output controller, wherein the connection end of the first power switching switch is connected to the photovoltaic power supply device 801, the rectifier and voltage stabilizing device 700, the first storage battery and the second storage battery, and the first power switching switch is used to control the photovoltaic power supply device 801 and the generator 5 to supply power to the first storage battery and the second storage battery respectively.

The drive gear 43 is sleeved and fixed on the drive main shaft 42 and rotates synchronously with the drive main shaft 42. A linkage rack 33 meshing with the drive gear 43 is provided on the power generation slide 3.

[0033] In this embodiment, an input gear 44 is fixedly installed on the drive main shaft 42, and an output gear 45 meshing with the input gear 44 is fixedly installed on the main shaft of the drive motor 41, so that the output gear 45 can drive the rotation of the drive main shaft 42, and at the same time, the drive gear 43 can drive the linkage rack 33 to move left and right, thereby realizing the left and right movement of the power generation slide 3.

[0034] In this embodiment, a proximity limit module 21 and a far-away limit module 22 are provided on the power generation base 2. Among them, the proximity limit module 21 is used to limit the maximum stroke when the power generation slide 3 moves towards the flywheel 1, and the far-away limit module 22 is used to limit the stroke when the power generation slide 3 moves away from the flywheel 1. Further, the proximity limit module 21 includes a proximity limit seat 211 provided on the power generation base 2 and a pressure sensor 212 provided on the proximity limit seat 211. The pressure sensor 212 is electrically connected to the power generation controller 600. When the power generation slide 3 presses against the pressure monitoring end of the pressure sensor 212, the detection data of the pressure sensor 212 is fed back to the power generation controller 600. If it exceeds the preset pressure value, the power generation controller 600 controls the drive motor 41 to stop, so that the power generation slide 3 stays at the current position, and the flywheel 1 and the pressure wheel 32 are kept in contact connection, thereby avoiding excessive extrusion of the flywheel 1 by the pressure wheel 32.

[0035] Furthermore, the far-away limit module 22 includes a separation position detection switch 221 installed on the power generation base 2. The power generation controller 600 is electrically connected to the separation position detection switch 221. When it is necessary to control the separation of the pressure wheel 32 from the flywheel 1, the power generation controller 600 controls the drive motor 41 to drive the power generation slide 3 to move away from the flywheel 1 until the separation position detection switch 221 detects the power generation slide 3, and then the power generation controller 600 stops the drive motor 41, so that the power generation slide 3 stays at the current position.

[0036] In this embodiment, the upper part of the power generation base 2 is provided with two mounting wheel frames 23 arranged front and back, and the two mounting wheel frames 23 are connected to a transmission shaft, and the transmission shaft is rotatably mounted on the mounting wheel frame 23 through a first bearing seat; the flywheel 1 is fixed on the transmission shaft and located between the two mounting wheel frames 23, and the transmission shaft is connected to the shaft of the traction main machine 300 through a coupling, so that the flywheel 1 can be driven to rotate synchronously when the traction main machine 300 rotates. In addition, the pressure wheel 32 includes a pressure wheel body and a rubber layer provided on the outer peripheral surface of the pressure wheel body, and the surface of the rubber layer can be provided with anti-skid grooves, so that the rubber layer and the anti-skid grooves can be better fitted on the outer peripheral surface of the flywheel 1, so that the pressure wheel 32 can be effectively driven to rotate by the flywheel 1. The anti-skid grooves are not shown in the drawings.

[0037] In this embodiment, at least two generator wheel frames 34 arranged from front to back are provided on the power generation slide 3, the power generation main shaft 31 is installed on the power generation wheel frame 34 through the power generation bearing, and the flexible transmission mechanism 6 includes a first transmission wheel 61 fixedly installed on the power generation main shaft 31, a second transmission wheel 62 fixedly installed on the rotating shaft of the generator 5, and a transmission belt 63 sleeved on the first transmission wheel 61 and the second transmission wheel 62, wherein the first transmission wheel 61 and the second transmission wheel 62 are both pulleys, and the transmission belt 63 is a transmission belt. When the pressure wheel 32 is driven to rotate by the flywheel 1, the power generation main shaft 31 drives the first transmission wheel 61 to rotate, and the transmission belt 63 drives the second transmission wheel 62 to rotate, so that the rotating shaft of the generator 5 rotates synchronously to achieve power generation. In addition, the diameter of the first transmission wheel 61 is larger than the diameter of the second transmission wheel 62, so that it can play a role in speed increase, increase the speed of the rotating shaft of the generator 5, and increase the power generation.

[0038] In this embodiment, a tensioning mechanism 35 for tensioning the transmission belt 63 is provided on the power generation base 2, and the tensioning mechanism 35 includes a tensioning base 351, a tensioning swing arm 352, a tensioning wheel 353 and a tensioning spring 354. The tensioning base 351 is installed on the power generation base 2, one end of the tensioning swing arm 352 is hingedly installed on the tensioning base 351 using a tensioning shaft, and the tensioning wheel 353 is rotatably installed on the other end of the tensioning swing arm 352. One end of the tensioning spring 354 is fixed to the middle part of the tensioning swing arm 352, and the other end is fixed to the tensioning base 351. The tensioning wheel 353 is pressed against the transmission belt 63 based on the elastic force of the tensioning spring 354, thereby achieving the purpose of tensioning the transmission belt 63.

[0039] As a preferred embodiment, the power generation device 500 further includes an emergency braking module 7 for cooperating with the flywheel 1 to stop the traction main engine 300. The emergency braking module 7 includes two braking sliders 71 slidably and guidingly mounted on the power generation base 2 and a braking main shaft 72 rotatably mounted on the power generation base 2. The two braking sliders 71 are respectively located on the front and rear sides of the flywheel 1, and a braking block 711 that can contact and separate from the flywheel 1 as it slides is mounted on each braking slider 71; a braking drive seat 73 that rotates synchronously with the braking main shaft 72 is mounted on the braking main shaft 72. The braking drive seat 73 is connected with a braking linkage mechanism 74 for driving the two braking sliders 71 to act synchronously. The braking drive seat 73 can connect and drive the braking linkage mechanism 74 to act when the braking main shaft 72 rotates, so that the action output end of the braking linkage mechanism 74 connects and drives the two braking sliders 71 to act.

[0040] Furthermore, a sector gear 46 is fixedly sleeved on the driving main shaft 42, and a braking gear 76 for cooperating with the sector gear 46 is fixedly sleeved on the braking main shaft 72; the away limiting module 22 further includes an away limiting seat 222 provided on the power generation base 2. A limiting tooth block 36 that can move left and right relative to it is slidably mounted at one end of the linkage rack 33 close to the flywheel 1. A tooth block spring 37 is provided between the limiting tooth block 36 and the linkage rack 33. The limiting tooth block 36 is used to replace the linkage rack 33 to cooperate with the driving gear 43 when the power generation slider 3 is blocked by the away limiting seat 222. Specifically: rack convex blocks are provided on both the front and rear sides of the linkage rack 33, rack screw holes are provided on the rack convex blocks, tooth block protrusions corresponding to the two rack convex blocks are provided on the limiting tooth block 36, tooth block through holes corresponding to the rack screw holes are provided on the tooth block protrusions, the screw section of a rack bolt 38 passes through the tooth block through hole and is threadedly engaged in the rack screw hole. A tooth block spring 37 is sleeved on the screw section of each rack bolt 38, and both ends of the tooth block spring 37 respectively abut against the rack convex block and the tooth block protrusion.

[0041] Under normal conditions (when the elevator brake is in normal use), the fan gear 46 and the brake gear 76 remain separated; when the power generation controller 600 learns from the elevator control device 400 that the original elevator brake of the elevator has failed, the power generation controller 600 controls the drive motor 41 to drive the power generation slide 3 to move in a direction away from the flywheel 1. During this process, the power generation slide 3 will not stop working even if the drive motor 41 is detected by the separation position detection switch 221, until the power generation slide 3 is pressed against the away limit seat 222, and the power generation slide 3 is restricted by the away limit seat 222 and cannot continue to move. At this time, the driving gear 43 continuously separates and meshes with the convex teeth of the limiting tooth block 36 during the rotation process. Each time the engagement occurs, the limiting tooth block 36 moves along the rack bolt 38 toward the driving gear 43 and compresses the tooth block spring 37. When the convex teeth of the limiting tooth block 36 are separated from the convex teeth of the driving gear 43, the tooth block spring 37 expands to reset the limiting tooth block 36 and re-engage with the next convex teeth of the driving gear 43. This action is repeated continuously, so that the power generation slide 3 is no longer driven to move away from the flywheel 1 during this process, thereby preventing the driving gear 43 from limiting the rotation of the driving spindle 42. Then, after the power generation controller 600 learns from the elevator control device 400 that the elevator car 100 is level, the power generation controller 600 controls the drive motor 41 to work, so that the fan gear 46 is driven by the drive main shaft 42 to rotate and mesh with the brake gear 76. As the drive main shaft 42 continues to rotate, the fan gear 46 drives the brake main shaft 72 to rotate synchronously, so that the brake drive seat 73 controls the action output end of the brake linkage mechanism 74 to link the two brake slides 71 to move, so that the two brake blocks 711 are respectively clamped on the front and rear sides of the flywheel 1, thereby realizing temporary braking of the elevator, allowing the elevator car 100 to stay at the nearest floor station, and the power generation controller 600 feeds back the temporary braking signal to the elevator control device 400, and the elevator control device 400 opens the car door and the floor door, so that passengers can walk out of the elevator by themselves, thereby reducing the probability of passengers being trapped in the elevator.

[0042] In this embodiment, the brake linkage mechanism 74 includes a brake secondary shaft 741, a brake execution swing arm 742 and a brake execution module, wherein the brake secondary shaft 741 can be rotatably mounted on the power generation base 2; the action input end of the brake execution module is transmission-connected to the brake drive seat 73, and the action output end is connected to the brake secondary shaft 741, so that the brake main shaft 72 can drive the brake secondary shaft 741 to rotate; the brake execution swing arm 742 is fixedly mounted on the brake secondary shaft 741, and swings with the rotation of the brake secondary shaft 741, and two brake linkage rods are provided on the brake execution swing arm 742, and the two brake linkage rods are respectively connected to the two brake slides 71, so as to control the movement of the brake slide 71 when the brake execution swing arm 742 swings.

[0043] In this embodiment, the braking execution module includes a braking linkage seat 744, a first execution connecting rod 745, a second execution connecting rod 746, and an execution adjusting rod 747. The braking linkage seat 744 is sleeved and fixed on the braking countershaft 741. One end of the first execution connecting rod 745 is hinged to the braking linkage seat 744, and a first adjusting nut 7451 is provided at the other end. One end of the second execution connecting rod 746 is hinged to the braking drive seat 73, and a second adjusting nut 7461 is provided at the other end. The thread rotation direction of the thread hole of the first adjusting nut 7451 is opposite to that of the second adjusting nut 7461. Both ends of the execution adjusting rod 747 are respectively provided with a first adjusting screw rod with one end thread-fitted in the thread hole of the first adjusting nut 7451 and a second adjusting screw rod with one end thread-fitted in the thread hole of the second adjusting nut 7461. By rotating the execution adjusting rod 747, the distance between the first execution connecting rod 745 and the second execution connecting rod 746 can be adjusted, so as to facilitate the debugging and control between the braking linkage seat 744 and the braking drive seat 73 and meet their linkage requirements.

[0044] In this embodiment, a braking base 24 is provided on the power generation base 2 in the installation space. A braking mounting seat 25 is mounted on the braking base 24. Two braking guide seats 251 arranged at intervals front and rear are mounted on the braking mounting seat 25.

The braking slide seat 71 is provided with an inclined guide groove, and the braking slide seat 71 is provided with a sliding guide portion that is guided and fitted in the inclined guide groove. The braking slide seat 71 moves closer to and away from the flywheel 1 in an inclined manner along the inclined guide groove.

[0045] In this embodiment, the braking mounting seat 25 is mounted on the braking base 24 with the height of the braking mounting bolts adjustable, so as to facilitate adjusting the height position of the braking slide seat 71 to adapt to the flywheel 1. Among them, the braking mounting seat 25 is provided with braking screw holes, and the braking base 24 is provided with braking long circular holes 241 extending from top to bottom in the length direction. The screw rod section of the braking mounting bolt passes through the braking long circular holes 241 and is thread-fitted in the braking screw holes, so that the height of the braking mounting seat 25 can be adjusted by the cooperation of the braking long circular holes 241 and the braking mounting bolts. Further, a braking support bolt 27 capable of lifting and moving is thread-mounted at the bottom of the braking base 24. The top of the screw rod section of the braking support bolt 27 supports the bottom of the braking mounting seat 25. After loosening the braking mounting bolts, the height position of the braking mounting seat 25 can be adjusted up and down by rotating the braking support bolt 27, so as to improve the convenience of mounting the braking mounting seat 25. At the same time, the braking support bolt 27 can also support the braking mounting seat 25 to ensure the mounting stability of the braking mounting seat 25. The braking mounting bolts are not shown in the drawings.

A pull hole is provided on the pull rod seat 758. One end of the tension spring 756 is hooked on the stop rotation mounting rod 753, and the other end is hooked in the pull hole. The tension spring 756 pulls the secondary shaft pull arm 752 by elastic force, so that the brake secondary shaft 741 drives the anti-rotation disk 751 to make the anti-rotation convex portion 7511 press against the anti-rotation limit block 26, thereby achieving the purpose of stopping the rotation of the brake secondary shaft 741 and avoiding abnormal braking caused by random rotation of the brake secondary shaft 741 when the sector gear 46 is separated from the brake gear 76.

[0049] In this embodiment, a rotation-stop detection groove 7512 is recessed on the outer peripheral surface of the rotation-stop disk 751. A rotation-stop monitoring switch 77 for cooperating with the rotation-stop detection groove 7512 to monitor whether the braking countershaft 741 rotates is installed on the power generation base 2. The rotation-stop monitoring switch 77 is electrically connected to the power generation controller 600. When the pressing monitoring end of the rotation-stop monitoring switch 77 is located in the rotation-stop detection groove 7512, it indicates that the braking countershaft 741 is effectively stopped from rotating. When the emergency braking module 7 is enabled, the braking main shaft 72 drives the braking countershaft 741 to synchronously drive the rotation-stop disk 751 to rotate. During the rotation of the rotation-stop disk 751, the pressing monitoring end of the rotation-stop monitoring switch 77 slides out of the rotation-stop detection groove 7512 and rolls on the outer peripheral surface of the rotation-stop disk 751. At this time, the rotation-stop monitoring switch 77 feeds back a monitoring signal to the power generation controller 600, so that the power generation controller 600 can understand the enabling state of the emergency braking module 7.

[0050] The above are only the preferred embodiments of the present invention. As long as the technical solutions that achieve the purpose of the present invention by basically the same means fall within the protection scope of the present invention.
