[0002] Hydropower is a renewable energy source that uses the kinetic energy of water to drive turbines, which in turn drive generators to generate electricity. Hydropower stations are typically built in locations with abundant water resources and fast-flowing currents, such as large rivers or waterfalls. Here, water is channeled through diversion channels into turbines, which are driven by the current and rotate. The rotating turbines are then connected to generators via transmissions, ultimately driving the generators and generating electricity.

[0003] After searching, the Chinese patent authorization number CN202121881197.6 discloses a safety brake control device for hydropower generation, which belongs to the field of hydropower generation technology. A safety brake control device for hydropower generation includes a brake pad, and also includes: a base for installation; a hydraulic cylinder fixedly connected to the bottom position of the base; a support plate and a brake seat, both slidably connected to the base; wherein the brake pad is fixedly connected to the upper end of the brake seat, the output end of the hydraulic cylinder is fixedly connected to the support plate, and the brake seat is located above the support plate; a plurality of support rods are arranged between the support plate and the brake seat; in the utility model, the brake seat is supported by the hydraulic cylinder, so that the brake pad at the upper end of the brake seat is pressed against the flywheel shaft to brake the flywheel, avoiding the need to manually pry the flywheel shaft with a wooden stick, thereby reducing the labor intensity of the staff and avoiding the situation where the staff may injure the waist when using the wooden stick to pry the flywheel shaft.

[0004] The above patents have the following deficiencies: in the above patents, the brake seat is directly supported and the braking effect is achieved by using the brake seat. However, during operation, it is difficult to adjust the angle of the brake seat. The flywheel shaft rotates at a relatively fast speed, and the supported brake seat will directly contact the flywheel shaft, which will pose certain safety hazards. Utility Model Content

[0005] The purpose of the present utility model is to provide a safety brake control device for hydropower generation, so as to solve the problem raised in the above background technology. In the above patent, the brake seat is directly supported and the brake effect is achieved by using the brake seat. However, during operation, it is difficult to adjust the angle of the brake seat. The flywheel shaft rotates at a fast speed, so the supported brake seat will directly contact the flywheel shaft, which will pose a certain safety hazard.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0034] See also Figure 1-2 As shown, this embodiment is a safety brake control device for hydropower generation, comprising:

[0035] The main body component includes a support frame 11 and a power generation disk 12;

[0036] The speed limiting component includes a transverse support rod 21, a hydraulic device 22, a transverse telescopic rod 23, a support block 24, a rubber brake pad 25, a motor 26, a turntable 27 and a rotating rod 28;

[0037] A hydraulic device 22 is provided at the left end of the top of the support frame 11. The middle of the right side of the outer wall of the hydraulic device 22 is connected to the transverse support rod 21. A transverse telescopic rod 23 is connected to the middle of the right side of the outer wall of the transverse support rod 21. The outer end of the transverse telescopic rod 23 is fixedly connected to the support block 24. A rubber brake pad 25 is installed on the outside of the support block 24.

[0038] A set of turntables 27 are symmetrically connected to the left end of the top of the support frame 11. The middle of the inner side of the turntable 27 is connected to the rotating rod 28. The hydraulic device 22 is connected to the outside of the rotating rod 28.

[0039] In this step, the motor 26 is operated, the turntable 27 rotates, and the rotating rod 28 on the inner wall rotates at the same time, so that the angle of the hydraulic device 22 can be adjusted. The angle of the rubber brake pad 25 is also adjusted at the same time. The rubber brake pad 25 is adjusted to an inclined angle so that the rubber brake pad 25 contacts the outer surface of the power generation disk 12. As friction is generated between the rubber brake pad 25 and the power generation disk 12, the wheel speed of the power generation disk 12 gradually decreases, and the rotating rod 28 rotates again, so that the rubber brake pad 25 is in a vertical state, thereby directly braking the power generation disk 12.

[0040] It also includes a fixing component, which includes a fixing block 31, a hole body 32, a fixing rod 33 and a limiting ring 34;

[0041] The front and rear ends of the support block 24 are provided with holes 32, and the left side of the outer wall of the rubber brake pad 25 is fixedly connected to the fixing block 31. The front and rear ends of the outer side of the fixing block 31 are connected to the fixing rod 33, and the fixing rod 33 is connected to the inside of the hole 32 by insertion.

[0042] The limiting ring 34 is separated from the fixing rod 33, and the rubber brake pad 25 is pulled out to the outside, so that the rubber brake pad 25 can be disassembled and replaced or maintained.

[0043] The outer surface of the fixed rod 33 is connected to the limiting ring 34, and the limiting ring 34 is attached to the left side of the outer wall of the support block 24;

[0044] When the fixed rod 33 is inserted into the hole 32 , the limiting ring 34 is simultaneously fixed to the outside of the fixed rod 33 to reinforce the inserted fixed rod 33 .

[0045] A support base 13 is welded to the bottom of the support frame 11, and a power generation disk 12 is connected to the middle of the inner wall of the support frame 11;

[0046] The support base 13 at the bottom can support the support frame 11 .

[0047] Working principle: first, the power generation disk 12 rotates normally to generate electricity;

[0048] Next, when the generator disk 12 needs to be braked, the motor 26 is turned on, the turntable 27 rotates, and the rotating rod 28 on the inner wall rotates at the same time, so that the angle of the hydraulic device 22 can be adjusted. The angle of the rubber brake pad 25 is also adjusted at the same time. The rubber brake pad 25 is adjusted to an inclined angle so that the rubber brake pad 25 contacts the outer surface of the generator disk 12. As friction is generated between the rubber brake pad 25 and the generator disk 12, the wheel speed of the generator disk 12 gradually decreases. The rotating rod 28 rotates again, making the rubber brake pad 25 vertical, thereby directly braking the generator disk 12.

[0049] As the use time of the rubber brake pad 25 continues to increase, the limiting ring 34 is separated from the fixing rod 33, and the rubber brake pad 25 is pulled outward, so that the rubber brake pad 25 can be disassembled and replaced or maintained.

[0052] As the angle of the transverse support rod 21 is adjusted, the universal ball 44 simultaneously rotates inside the universal ball 44, and rotates according to the angle adjusted by the transverse support rod 21, so that the clamping ring 45 is completely clamped at the bottom of the transverse support rod 21, supporting the transverse support rod 21 and improving stability during operation.

[0053] The outer surface of the vertical support rod 41 is connected to an internal threaded ring 46 , the middle of the internal threaded ring 46 is connected to a threaded rod 48 , and the outer end of the threaded rod 48 is rotatably connected to a handle 47 ;

[0054] According to the angle adjusted by the horizontal support rod 21 , the vertical telescopic rod 42 is telescopically adjusted inside the vertical support rod 41 , and then the threaded rod 48 is rotated so that the threaded rod 48 is clamped and fixed on the outside of the vertical telescopic rod 42 .

[0055] Working principle: After the angle adjustment of the horizontal support rod 21 is completed, the threaded rod 48 is rotated so that the threaded rod 48 is clamped on the outside of the vertical telescopic rod 42 to fix the adjusted height of the vertical telescopic rod 42;

[0056] The universal ball 44 simultaneously rotates inside the universal ball 44 and rotates according to the angle adjusted by the transverse support rod 21, so that the clamping ring 45 is completely clamped at the bottom of the transverse support rod 21, supporting the transverse support rod 21 and improving stability during operation.
