The crankshaft includes multiple crankshaft body segments, main journal segments, and connecting rod journal segments. The multiple crankshaft body segments are arranged at intervals along the length of the crankshaft, and any two adjacent crankshaft body segments are connected by a main journal segment or a connecting rod journal segment. The drive unit comprises several groups, each group including a lever and a connecting rod. The lever uses the fixed frame as a fulcrum, with one end being a free end and the other end rotatably connected to the connecting rod. The connecting rod is also rotatably connected to one of the connecting rod journal segments. The generator is connected to one of the crankshaft body segments, and the rotation of the crankshaft drives the generator to generate electricity.

[0005] The lever-driven power generation device of this utility model drives the connecting rod journal section to reciprocate through the free end of the driving lever, which in turn drives the crankshaft to rotate. When the crankshaft rotates, the crankshaft body section drives the generator to rotate, and the generator can generate electricity. By setting several sets of lever devices, different power generation needs can be met. In case of emergency when no energy is available, the lever devices can also be driven manually.

[0006] As a preferred embodiment, the crankshaft further includes a balance block that rotates with the crankshaft. By including the balance block, the inertial forces during crankshaft rotation can be balanced, improving the stability of the crankshaft during operation.

[0007] As a preferred embodiment, the drive unit has 3 to 20 sets. With 3 or more sets of drive units, when the crankshaft rotates to different positions, there is a lever in a suitable drive position, ensuring a continuous power input to the crankshaft.

[0008] As a preferred embodiment, the generator includes a rotor, and the crankshaft body section is drive-connected to the rotor.

[0009] As a preferred embodiment, the system also includes a transmission device, which is connected to the crankshaft body section and to the rotor.

[0011] As a preferred embodiment, the transmission device further includes a second transmission device, which includes a second driving wheel, a second driven wheel, and a second transmission shaft. The two ends of the second transmission shaft are rotatably connected to the fixed frame, and the second driving wheel and the second driven wheel are fixed to the second transmission shaft. The first driving wheel is drivingly connected to the second driven wheel, and the second driving wheel is drivingly connected to the rotor.

[0012] As a preferred embodiment, the transmission ratio between the crankshaft body section and the first driven wheel is 3 to 10, the transmission ratio between the first driving wheel and the first driven wheel is 3 to 10, the transmission ratio between the first driving wheel and the second driven wheel is 3 to 10, and the transmission ratio between the second driving wheel and the second driven wheel is 3 to 10. By increasing the transmission ratio, the output speed is increased.

[0013] As a preferred embodiment, the fixing frame includes a support rod with several support seats. The lever is fixed to the support seats and uses the support seats as fulcrums. Fixing the lever to the fixing frame prevents slippage when the lever is driven. Attached Figure Description

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] like Figures 1-2 As shown, the lever power generation device of this utility model includes a fixed frame 1, a crankshaft 2, a drive device, a first speed change device, a second speed change device, a generator 6, and a belt 7.

[0022] The fixed frame 1 includes a support rod 11, which has three support seats 12. The two ends of the crankshaft 2 are rotatably connected to the fixed frame 1. The crankshaft 2 includes multiple crankshaft body sections 21, main journal sections 22, connecting rod journal sections 23, and a balance block 24. The multiple crankshaft body sections 21 are arranged at intervals along the length of the crankshaft 2. A main journal section 22 or a connecting rod journal section 23 is connected between any two adjacent crankshaft body sections 21. The balance block 24 can rotate with the crankshaft 2. There are three sets of drive devices. Each set of drive devices includes a lever 31 and a connecting rod 32. The lever 31 is fixed to the support seat 12 and uses the support seat 12 as a fulcrum. One end is a free end, and the other end is rotatably connected to the connecting rod 32. The connecting rod 32 is also rotatably connected to one of the connecting rod journal sections 23.

[0023] The first transmission device includes a first drive shaft 41, a first driven wheel 42, and a first driving wheel 43. Both ends of the first drive shaft 41 are rotatably connected to a fixed frame 1. The first driven wheel 42 and the first driving wheel 43 are fixed to the first drive shaft 41. The first driven wheel 42 is connected to one of the crankshaft body sections 21 via gear transmission. The transmission ratio between the crankshaft body section 21 and the first driven wheel 42 is 3, and the transmission ratio between the first driving wheel 43 and the first driven wheel 42 is 5. The second transmission device includes a second drive shaft 51 and a second driven wheel. The second driven wheel 52 and the second driving wheel 53 are respectively rotatably connected to the fixed frame 1 at both ends of the second drive shaft 51. The second driven wheel 52 and the second driving wheel 53 are respectively fixed to the second drive shaft 51. The second driven wheel 52 is connected to the first driving wheel 43 via a belt 7. The transmission ratio between the first driving wheel 43 and the second driven wheel 52 is 5:5. The transmission ratio between the second driving wheel 53 and the second driven wheel 52 is also 5:5. The generator 6 includes a rotor 61, which is fixed to the fixed frame 1. The rotor 61 is connected to the second driving wheel 53 via a belt 7. In other embodiments, transmission can also be achieved through chains, gears, etc.

[0024] When the free end of one of the levers 31 is driven, the lever 31 uses the support seat 12 as a fulcrum and drives the crankshaft 2 to rotate through the connecting rod 32. When the crankshaft 2 rotates, on the one hand, it drives the first driven wheel 42 to rotate, and the speed is increased through the first and second speed change devices, which drives the rotor 61 of the generator 6 to rotate and output current; on the other hand, it drives the free ends of the other levers 31 to enter the appropriate driving position. In this embodiment, three sets of levers 31 are set. When the crankshaft 2 rotates to different positions, the free ends of the levers 31 are in the appropriate driving position, so that the crankshaft 2 has a continuous power input. In addition, when the crankshaft 2 rotates, it also drives the balance block 24 to rotate, which balances the inertial force when the crankshaft 2 rotates and improves the stability of the crankshaft 2 during operation.

[0025] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. For those skilled in the art, various modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
