[0020] A load adaptation device for lever hydroelectric power generation, as Figures 1 - 5 shown, comprising an installation frame 1. A through hole is provided in the middle of the installation frame 1. A driving motor 2 is installed on the left side of the rear part of the installation frame 1. Both the left and right sides of the front part of the installation frame 1 are connected with bearings 4. A rotating member 3 is installed between the bearings 4. The rotating member 3 includes a rotating rod and a driving wheel. A rotating rod is connected between the bearings 4, and a driving wheel is connected to the rotating rod. A driving wheel is also connected to the output shaft of the driving motor 2. Anti-slip lines are provided on the surfaces of the driving wheels. Electric push rods 5 are connected to both the left and right sides of the middle part of the installation frame 1. An installation frame 6 is connected between the telescopic ends of the electric push rods 5. The installation frame 6 is slidably connected to the installation frame 1. A rotating wheel 7 is rotatably connected to the installation frame 6. An installation sleeve 8 is installed on the left side of the rotating rod. The installation sleeve 8 is connected to a lever device. The right side of the rotating rod is connected to a generator. A number of clamping members 10 are rotatably connected to the installation sleeve 8. Elastic members 11 are connected between the clamping members 10 and the installation sleeve 8. Sliding seats 14 are connected to both the front and rear sides of the lower part of the installation frame 1. The sliding seats 14 are slidably connected to fixed sliding grooves 12. Installation holes are provided on both the left and right sides of the front part of the fixed sliding grooves 12. A lead screw 13 is rotatably connected to the fixed sliding grooves 12. A wrench for facilitating the rotation of the lead screw 13 is provided at the front end of the lead screw 13. The lead screw 13 and the sliding seats 14 are both threadedly connected.
[0021] It should be noted that lever hydroelectric power generation is an innovative hydroelectric power generation technology that uses the lever principle and the gravity of water to generate electricity. Based on the original method that mainly relies on the water level drop to generate kinetic energy to drive the water turbine, it can also generate electricity effectively under low water level conditions. However, when the water level is low, the lever device may rotate slowly, affecting the power generation efficiency. Prolonged idling may damage the generator and affect its service life. First, turn the screw rod 13 with a wrench to drive the sliding seat 14 to move, so as to adjust the sliding seat 14 to a suitable position. Then connect the lever device to the rotating sleeve 9, and install the generator on the right side of the rotating rod. When the water level is high, it drives the rotating sleeve 9 to rotate. The card slot on the rotating sleeve 9 is engaged with the engaging part, thereby driving the mounting sleeve 8, the rotating rod, and the driving wheel to rotate successively, so as to drive the generator to generate electricity. When the low water level affects the rotation speed of the lever device, turn on the electric push rod 5. The telescopic end of the electric push rod 5 drives the mounting bracket 6 to move downward, so that the rotating wheel 7 contacts the driving wheel. Then turn on the driving motor 2. The output shaft of the driving motor 2 rotates to drive the adjacent driving wheel to rotate, and then drives the rotating wheel 7 and the other driving wheel to rotate successively, so as to drive the rotating rod to rotate. The rotation of the rotating rod causes the mounting sleeve 8 and the clamping member 10 to rotate successively. Since there is a card slot on the rotating sleeve 9, in the initial state, the card slot is engaged with the clamping member 10. As the mounting sleeve 8 rotates, the clamping member 10 will rotate in the same direction. Since the lever device stops operating and the rotating sleeve 9 is connected to the lever device, the rotating sleeve 9 is in a relatively stationary state. When the clamping member 10 disengages from the card slot, the smooth inner wall of the rotating sleeve 9 will squeeze the clamping member 10 to rotate downward, thereby compressing the elastic member 11, so as to achieve the idling of the rotating sleeve 9, so as to achieve the effect of assisting the normal rotation of the rotating rod when the rotation speed is low at low water level, thereby ensuring the stable rotation speed of the generator and the continuous and stable output of power generation efficiency.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
