[0013] (III) Beneficial Effects
[0014] Compared with the prior art, this utility model provides a wind power compensation device based on flexible energy storage technology, which has the following beneficial effects:
[0015] 1. In this utility model, by setting up a connecting mechanism and a first motor, the output end of the wind turbine can be connected to the first motor. When the wind turbine generates excessive electrical energy, the excess electrical energy can drive the first motor to work, realizing the conversion of electrical energy into mechanical energy. At the same time, considering the problems of the first motor speed being too fast and insufficient torque, a gearbox is used to increase the torque to ensure stable energy input to the vortex spring.
[0016] 2. In this utility model, through the installation mechanism, after the mounting block is inserted into the mounting cover, the handle can be used to tighten the internal hex bolt, thereby driving the bidirectional screw and the first bevel gear to rotate.

Then, through the threaded engagement between the bidirectional screw and the positioning block, one end of the positioning block is driven to extend into the first positioning groove. Thus, the positioning of the mounting block and the mounting cover is achieved through the engagement of the positioning block and the first positioning groove, thereby enabling the connection and fixation of the adjacent first support rod and second support rod.
[0017] 3. In this utility model, by setting up an energy storage mechanism, the operation of the first motor can drive the first support rod to rotate through the transmission of the first gear and the second gear, so that the spiral spring undergoes elastic deformation when subjected to working torque, storing elastic potential energy, thereby facilitating the storage of excess electrical energy.
[0018] 4. In this utility model, by setting up a power generation mechanism, when energy needs to be released, the electromagnetic clutch is engaged, causing the vortex spring to release its elastic potential energy, thereby driving the first generator to rotate and generate electricity. Simultaneously, considering that the DC power generated by the generator cannot be directly connected to the grid, a converter can be used to convert the DC power into AC power and adjust the voltage and frequency to national standards for grid connection, thus facilitating the maintenance of power system stability.

[0027] Please see Figures 1-6 A wind power compensation device based on flexible energy storage technology includes a support frame 1 and a first motor 2. The first motor 2 is mounted on the support frame 1. The device also includes a support housing 3, an energy storage mechanism, a power generation mechanism, and a connecting mechanism. Multiple support housings 3 are provided on one side of the support frame 1. The energy storage mechanism is located inside the support housing 3 and is used to store electricity. The power generation mechanism is located on one side of the multiple support housings 3 and is used to release the stored electricity. The connecting mechanism is located between the first motor 2 and the energy storage mechanism and is used to transmit the mechanical energy output by the first motor 2 to the energy storage mechanism.
[0028] Reference Figures 1-6 The energy storage mechanism includes a first support rod 4 and a second support rod 5, a support plate 6, a spiral spring 7, and an installation mechanism. The first support rod 4 and the second support rod 5 are rotatably and through the two opposite side walls of the support housing 3. The support plate 6 is fixedly installed at one end of the first support rod 4 near the support housing 3. The spiral spring 7 is installed inside the support housing 3, and its two ends are fixedly connected to the adjacent support plate 6. The installation mechanism is installed between the two adjacent support housings 3 for installing and fixing the adjacent first support rod 4 and second support rod 5. Specifically, the operation of the first motor 2 can drive the first support rod 4 to rotate through the transmission of the first gear 17 and the second gear 18, so that the spiral spring 7 undergoes elastic deformation when subjected to working torque, storing elastic potential energy, thereby facilitating the storage of excess electrical energy.
[0029] Reference Figures 3-6The installation mechanism includes a mounting cover 8, a mounting block 9, and a positioning mechanism. The mounting cover 8 is fixedly mounted on a second support rod 5 near the adjacent support housing 3. The mounting block 9 is fixedly mounted on a first support rod 4 near the adjacent support housing 3. The mounting block 9 extends into the adjacent mounting cover 8 and is slidably connected to the inner wall of the mounting cover 8. The positioning mechanism is mounted on the mounting cover 8 and is used to position the mounting block 9 and the mounting cover 8. The positioning mechanism includes a first positioning groove 10, a second positioning groove 11, a positioning block 12, a bidirectional screw 13, a first cavity, a second bevel gear 15, and an internal hexagon bolt 16. The side wall of the mounting block 9 has an annular first positioning groove 10. The inner wall of the mounting cover 8 has multiple second positioning grooves 11. An L-shaped positioning block 12 is slidably mounted in the second positioning groove 11. The bidirectional screw 13 is rotatably mounted in the second positioning groove 11 and passes through the positioning block 12 through a threaded engagement. The first cavity is opened inside the mounting cover 8. One end of the mounting block 9 extends into the first cavity and is fixedly mounted with a first bevel gear 14. A second bevel gear 15 is rotatably mounted on the side wall of the first cavity and meshes with the first bevel gear 14. An internal hex bolt 16 is rotatably mounted on the side wall of the mounting cover 8 and is fixedly connected to a nearby double-ended screw 13. Specifically, after the mounting block 9 is inserted into the mounting cover 8, the handle can be used to turn the internal hex bolt 16, thereby driving the double-ended screw 13 and the first bevel gear 14 to rotate. At the same time, the meshing of the first bevel gear 14 and the second bevel gear 15 drives multiple double-ended screws 13 to rotate synchronously. Then, through the threaded engagement of the double-ended screw 13 and the positioning block 12, one end of the positioning block 12 is driven to extend into the first positioning groove 10. The engagement of the positioning block 12 and the first positioning groove 10 achieves the positioning between the mounting block 9 and the mounting cover 8, thereby achieving the connection and fixation of the nearby first support rod 4 and second support rod 5.
[0030] Reference Figure 1 and Figure 2 The connecting mechanism includes a first gear 17, a second gear 18, and a gearbox 19. The first gear 17 is rotatably mounted on the support frame 1 and is fixedly connected to the adjacent first support rod 4. The second gear 18 is rotatably mounted on the support frame 1, and the first gear 17 and the second gear 18 mesh. The gearbox 19 is mounted on the support frame 1, and the input end of the gearbox 19 is connected to the output end of the first motor 2. The output end of the gearbox 19 is fixedly connected to the second gear 18. Specifically, the output end of the wind turbine can be connected to the first motor 2. When the wind turbine generates excess electrical energy, the excess electrical energy can drive the first motor 2 to work, realizing the conversion of electrical energy into mechanical energy. At the same time, considering the problems of the first motor 2 rotating too fast and having insufficient torque, the gearbox 19 is used to increase the torque to ensure stable energy input to the vortex spring 7.
[0031] Reference Figure 1 and Figure 2 The power generation mechanism includes a mounting frame 20, a braking electromagnetic clutch 22, and a converter 23. The mounting frame 20 is located on one side of multiple support housings 3, and a first generator 21 is mounted on the mounting frame 20. The braking electromagnetic clutch 22 is mounted on a support housing 3 near the mounting frame 20, and its working end is fixedly connected to a nearby second support rod 5 and the input end of the first generator 21, respectively. The converter 23 is located on one side of the mounting frame 20 and is electrically connected to the first generator 21. Specifically, when energy needs to be released, the electromagnetic clutch is engaged, causing the vortex spring 7 to release its elastic potential energy, thereby driving the first generator 21 to rotate and generate electricity. Considering that the direct current generated by the generator cannot be directly connected to the grid, the converter 23 converts the direct current into alternating current and adjusts the voltage and frequency to national standards for grid connection, thus facilitating the maintenance of power system stability.
[0032] Working principle: During use, after the operator inserts the mounting block 9 into the mounting cover 8, they can use the handle to tighten the hex bolt 16, thereby driving the bidirectional screw 13 and the first bevel gear 14 to rotate. Simultaneously, the meshing of the first bevel gear 14 and the second bevel gear 15 drives multiple bidirectional screws 13 to rotate synchronously. The threaded engagement between the bidirectional screws 13 and the positioning block 12 causes one end of the positioning block 12 to extend into the first positioning groove 10. The engagement between the positioning block 12 and the first positioning groove 10 achieves positioning between the mounting block 9 and the mounting cover 8, thus connecting and fixing the adjacent first support rod 4 and second support rod 5. Afterwards, the operator connects the wind turbine's output end... Connected to the first motor 2, when the wind turbine generates excess electrical energy, the excess electrical energy can drive the first motor 2 to work, realizing the conversion of electrical energy into mechanical energy. At the same time, considering the problems of excessive speed and insufficient torque of the first motor 2, a gearbox 19 is used to increase the torque, ensuring a stable energy input to the vortex spring 7. The operation of the first motor 2, through the transmission of the first gear 17 and the second gear 18, can drive the first support rod 4 to rotate, so that the vortex spring 7 undergoes elastic deformation when subjected to working torque, storing elastic potential energy, thus facilitating the storage of excess electrical energy. When energy needs to be released, the operator engages the electromagnetic clutch, causing the vortex spring 7 to release its elastic potential energy, thereby driving the first generator 21 to rotate and generate electricity. At the same time, considering that the DC power generated by the generator cannot be directly connected to the grid, the converter 23 can convert the DC power into AC power and adjust the voltage and frequency to the national standard for grid connection, thus facilitating the maintenance of power system stability.
