[0022] In this embodiment, an input gear 44 is fixedly installed on the driving main shaft 42, and an output gear 45 meshing with the input gear 44 is fixedly installed on the main shaft of the driving motor 41, so that the output gear 45 can drive the rotation of the driving main shaft 42, and also allow the driving gear 43 to drive the linkage rack 33 to move left and right, thereby realizing the left and right movement of the power generation slide 3.

[0023] In this embodiment, the power generation base 2 is provided with a close limit module 21 and a far limit module 22, wherein the close limit module 21 is used to limit the maximum stroke of the power generation slide 3 when it moves toward the flywheel 1, and the far limit module 22 is used to limit the stroke of the power generation slide 3 when it moves away from the flywheel 1. Further, the close limit module 21 includes a close limit seat 211 provided on the power generation base 2 and a pressure sensor 212 provided on the close limit seat 211, and the pressure sensor 212 is electrically connected to the power generation controller 600. When the power generation slide 3 is pressed 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 the pressure exceeds the preset pressure value, the power generation controller 600 controls the driving motor 41 to stop, so that the power generation slide 3 stays at the current position, so that the flywheel 1 and the pressure wheel 32 remain in contact and connected state, thereby preventing the pressure wheel 32 from excessively squeezing the flywheel 1.

[0024] Furthermore, the distance limit module 22 includes a separation position detection switch 221 installed on the power generation base 2, and the power generation controller 600 is electrically connected to the separation position detection switch 221. When it is necessary to control the pressure wheel 32 to separate from the flywheel 1, the power generation controller 600 controls the drive motor 41 to link 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. Then, the power generation controller 600 stops the drive motor 41 to make the power generation slide 3 stay at the current position.

[0025] 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.

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.

[0027] 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.

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.

[0028] As a preferred embodiment, the power generation device 500 also includes an emergency brake module 7 for cooperating with the flywheel 1 to stop the traction main engine 300. The emergency brake module 7 includes two brake slides 71 with sliding guides installed on the power generation base 2 and a brake main shaft 72 rotatably installed on the power generation base 2. The two brake slides 71 are respectively located on the front and rear sides of the flywheel 1. Each brake slide 71 is installed with a brake block 711 that can contact and separate from the flywheel 1 as it slides; the brake main shaft 72 is installed with a brake drive seat 73 that rotates synchronously with it, and the brake drive seat 73 is connected to a brake linkage mechanism 74 that drives the two brake slides 71 to move synchronously. The brake drive seat 73 can be connected to drive the brake linkage mechanism 74 to move when the brake main shaft 72 rotates, so that the action output end of the brake linkage mechanism 74 is connected to drive the two brake slides 71 to move.

[0029] Furthermore, the driving main shaft 42 is fixedly sleeved with a fan gear 46, and the brake main shaft 72 is fixedly sleeved with a brake gear 76 for cooperating with the fan gear 46; the distance limit module 22 also includes a distance limit seat 222 arranged on the power generation base 2, and the linkage rack 33 is slidably installed with a limit tooth block 36 that can move left and right relative to the flywheel 1. A tooth block spring 37 is provided between the limit tooth block 36 and the linkage rack 33. The limit tooth block 36 is used to replace the linkage rack 33 and cooperate with the driving gear 43 when the power generation slide 3 is blocked by the distance limit seat 222. Specifically: rack protrusions are provided on the front and rear sides of the linkage rack 33, and rack screw holes are provided on the rack protrusions. The limiting tooth block 36 is provided with two tooth block protrusions corresponding to the two rack protrusions respectively, and the tooth block protrusions are provided with tooth block through holes corresponding to the rack screw holes. The screw section of the 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 installed on the screw section of each rack bolt 38, and the two ends of the tooth block spring 37 are respectively abutted against the rack protrusion and the tooth block protrusion.

[0030] 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.

The tension spring 756 uses elastic force to pull the secondary shaft pulling arm 752, so that the brake secondary shaft 741 is linked with the anti-rotation plate 751 to make the anti-rotation protrusion 7511 press against the anti-rotation limit block 26, thereby achieving the purpose of stopping the brake secondary shaft 741 and avoiding abnormal braking caused by arbitrary rotation of the brake secondary shaft 741 when the fan gear 46 is separated from the brake gear 76.

[0038] In this embodiment, a stop detection groove 7512 is recessed on the outer circumference of the stop disk 751, and a stop monitoring switch 77 is installed on the power generation base 2 for cooperating with the stop detection groove 7512 to monitor whether the brake secondary shaft 741 rotates, and the stop monitoring switch 77 is electrically connected to the power generation controller 600. When the pressing monitoring end of the stop monitoring switch 77 is located in the stop detection groove 7512, it indicates that the brake secondary shaft 741 is effectively stopped. When the emergency brake module 7 is enabled, the brake main shaft 72 drives the brake secondary shaft 741 to rotate synchronously with the stop disk 751. During the rotation of the stop disk 751, the pressing monitoring end of the stop monitoring switch 77 slides out of the stop detection groove 7512 and rolls on the outer circumference of the stop disk 751. At this time, the 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 enabled state of the emergency brake module 7.

[0039] The above description is only a preferred embodiment of the present invention. Any technical solution that achieves the purpose of the present invention by substantially the same means belongs to the protection scope of the present invention.
