It is the core component of a wind power station, and the wind power generation equipment has a large number of component structures, and different parts have different functions. The wind power speed increaser is a core component in the transmission system of the wind turbine generator, and mainly functions to convert the low-speed and high-torque mechanical energy captured by the wind wheel into high-speed and low-torque mechanical energy required by the generator, so as to drive the generator to generate electricity efficiently.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-9 The present invention provides a technical solution: a high-speed shaft locking device for a wind power speed increaser in a wind power generation device, comprising a mounting base 3, an adjusting motor 2 fixedly mounted on the side wall of the mounting base 3, a bidirectional stud 11 fixedly mounted on one end of the output shaft of the adjusting motor 2, two locking brackets 1 movably mounted on the mounting base 3, and sliders 10 fixedly mounted on the bottom surface of the two locking brackets 1, the bidirectional stud 11 being threadedly connected to the threaded holes provided inside the two sliders 10, the sliders 10 being slidably mounted in the sliding grooves 5 provided inside the mounting base 3, and shaft holes 4 being provided on the inner side of the two locking brackets 1; The auxiliary locking assembly 7 and the step-by-step locking mechanism 8 are used for step-by-step locking of the high-speed shaft of the speed increaser, and the auxiliary locking assembly 7 is used for auxiliary locking of the high-speed shaft of the speed increaser. Multiple side shells 6 are fixedly installed on one side outer wall of the locking frame 1. The auxiliary locking assembly 7 is located inside the side shell 6. Several mounting grooves 13 are provided on the inner surface of the shaft hole 4. The step-by-step locking mechanism 8 is located inside the mounting grooves 13. The step-by-step locking mechanism 8 includes a mounting plate 82, which is movably mounted inside the mounting groove 13 via a connecting spring 81. A compression cone 83 is fixedly mounted on one outer wall of the mounting plate 82, and a spring telescopic shaft 88 is fixedly mounted on the other outer wall of the mounting plate 82. A locking piece 86 is fixedly mounted at one end of the spring telescopic shaft 88, and side plates 84 are fixedly mounted at both ends of the locking piece 86. The side plates 84 are slidably connected to the mounting groove 13.

[0031] Furthermore: When locking the high-speed shaft of the speed increaser, the drive motor 74 is directly driven to open, driving the drive gear 72 to rotate. The rotating drive gear 72 continuously pushes the push rod 9 to move. When the push rod 9 moves, the conical head 14 at one end can squeeze one side of the extrusion cone 83 of the step-by-step locking mechanism 8. As the push rod 9 moves, the extrusion cone 83 can be gradually pressed down, causing the locking plate 86 to move down until it contacts the high-speed rotating shaft, thus slowing it down. When the push rod 9 moves to its maximum position, each set of step-by-step locking mechanisms 8 is squeezed out simultaneously. Multiple sets of step-by-step locking mechanisms 8 achieve deceleration and locking of the high-speed shaft. During the locking process, since each set of step-by-step locking mechanisms 8 is equipped with a spring telescopic shaft 88, the locking plate 86 can adaptively adjust according to the surface of the shaft, so that each set of step-by-step locking mechanisms 8 can make good contact with the shaft for deceleration and locking.

[0032] This design replaces the traditional independent locking mechanism with multiple sets of progressively locking mechanisms 8. It can lock not only stationary shafts but also high-speed rotating shafts. Moreover, the locking structure adopts a split design, gradually decelerating and locking the shaft during the locking process, preventing rapid wear of the overall structure and making the deceleration and locking of the shaft more stable and less prone to damage. At the same time, the locking structure works independently and can adaptively adjust according to the flatness of the shaft's exterior without affecting the operation of other locking structures, greatly improving the practical application effect of the device.

[0033] Please see Figures 8-9A side groove 85 is provided on one side of the side plate 84. An expansion component 87 is movably installed on the inner side of the side groove 85. The expansion component 87 includes a primary expansion plate 876. The primary expansion plate 876 is rotatably installed inside the side groove 85 via a second side shaft 878. A second torsion spring 873 is provided on the outside of the second side shaft 878. One end of the second torsion spring 873 is fixedly connected to the inner wall of the side groove 85. One end of the primary expansion plate 876 is provided with a cut surface, and a plurality of locking protrusions 875 are provided on the cut surface. A plate groove 874 is provided on one side of the primary expansion plate 876. A secondary expansion plate 872 is movably installed on the inner side of the plate groove 874 via a first side shaft 877. A first torsion spring 871 is provided on the outside of the first side shaft 877. One end of the first torsion spring 871 is fixedly connected to the inner wall of the plate groove 874.

[0034] Furthermore, when the step-by-step locking mechanism 8 moves down to lock the shaft, after the outer side of the first-stage expansion plate 876 is no longer blocked, it can deflect outward under the action of the second torsion spring 873. At the same time, the second-stage expansion plate 872 can also deflect outward synchronously under the action of the first torsion spring 871. At this time, the first-stage expansion plate 876, the second-stage expansion plate 872 and the locking plate 86 form an expanded structure, which further increases the contact area with the shaft and further improves the deceleration and locking effect on the shaft. When the push rod 9 is driven to reset, each set of step-by-step locking mechanisms 8 can be retracted and reset under the action of its connecting spring 81. At this time, the expansion component 87 can also be automatically retracted into the side groove 85.

[0035] Through this design, when the step-by-step locking mechanism 8 locks the shaft, the extension component 87 on it can automatically expand, increasing the contact area and contact point with the shaft, further improving the deceleration and locking effect on the shaft, and further improving the application effect of the structure.

[0036] Please see Figure 7 The auxiliary locking assembly 7 includes a drive motor 74, which is fixedly installed in the cavity of the side shell 6. One end of the output shaft of the drive motor 74 is fixedly mounted with a mounting shaft 73. One end of the mounting shaft 73 is externally mounted with a bushing 75, which has frictional resistance with the mounting shaft 73. One end of the bushing 75 is fixedly mounted with a locking cam 71. A drive gear 72 is fixedly mounted on the outside of the mounting shaft 73. The locking frame 1 has an internal mounting channel, in which a push rod 9 is movably mounted. One end of the push rod 9 is fixedly mounted with a conical head 14, which is located on one side of the extrusion cone head 83. The drive gear 72 and the external meshing groove of the push rod 9 are meshed and connected. A plurality of movable grooves 12 are provided on one side of the outer wall of the locking frame 1, which are located on one side of the locking cam 71.

[0037] Furthermore, when the drive gear 72 starts to rotate, the locking cam 71 can also rotate synchronously. When the locking cam 71 rotates to contact the shaft, it stops rotating. At this time, since the bushing 75 and the mounting shaft 73 are movably connected, the mounting shaft 73 can continue to rotate, driving the push rod 9 to move. At this time, one end of each rotating locking cam 71 can contact the outside of the shaft and apply pressure to the shaft, realizing auxiliary deceleration and locking of the shaft. The overall locking frame 1 is designed as a split type. When it is necessary to repair the speed increaser shaft, the external adjustment motor 2 can be directly turned on to drive the bidirectional stud 11 to rotate. The bidirectional stud 11 can drive the two sliders 10 on it to move away from each other. At this time, the two locking frames 1 are driven away from each other, and the two locking frames 1 can be completely opened to facilitate the repair of the shaft.

[0038] This design allows the auxiliary locking components to work in sync with the step-by-step locking mechanism, further improving the locking effect of the device. It also enables the locking frame to be quickly separated when needed, facilitating subsequent maintenance.

[0039] Working principle: When locking the high-speed shaft of the speed increaser, the drive motor 74 is directly driven to open, driving the drive gear 72 to rotate. The rotating drive gear 72 continuously pushes the push rod 9 to move. When the push rod 9 moves, the conical head 14 at one end can squeeze one side of the extrusion cone 83 of the step-by-step locking mechanism 8. As the push rod 9 moves, the extrusion cone 83 can be gradually pressed down, causing the locking plate 86 to move down until it contacts the high-speed rotating shaft and decelerates it. When the push rod 9 moves to the maximum position, each group of step-by-step locking mechanisms 8 is squeezed out at the same time. Multiple groups of step-by-step locking mechanisms 8 achieve deceleration and locking of the high-speed shaft. During the locking process, since each group of step-by-step locking mechanisms 8 is equipped with an elastic telescopic shaft 88, the locking plate 86 can adaptively adjust according to the surface of the shaft, so that each group of step-by-step locking mechanisms 8 can make good contact with the shaft to decelerate and lock. When the step-by-step locking mechanism 8 moves down to lock the shaft, after the outer side of the first-stage expansion plate 876 is no longer blocked, it can deflect outward under the action of the second torsion spring 873. At the same time, the second-stage expansion plate 872 can also deflect outward synchronously under the action of the first torsion spring 871. At this time, the first-stage expansion plate 876, the second-stage expansion plate 872 and the locking plate 86 form an expanded structure, which further increases the contact area with the shaft and further improves the deceleration and locking effect on the shaft. When the push rod 9 is driven to reset, each set of step-by-step locking mechanisms 8 can be retracted and reset under the action of its connecting spring 81. At this time, the expansion component 87 can also be automatically retracted into the side groove 85. When the drive gear 72 starts to rotate, the locking cam 71 can also rotate synchronously. When the locking cam 71 rotates to contact the shaft, it stops rotating. At this time, since the bushing 75 and the mounting shaft 73 are movably connected, the mounting shaft 73 can continue to rotate, driving the push rod 9 to move. At this time, one end of each rotating locking cam 71 can contact the outside of the shaft and apply pressure to the shaft to achieve auxiliary deceleration and locking of the shaft. The overall locking frame 1 is designed as a split type. When it is necessary to repair the speed increaser shaft, the external adjustment motor 2 can be directly turned on to drive the bidirectional stud 11 to rotate. The bidirectional stud 11 can drive the two sliders 10 on it to move away from each other. At this time, the two locking frames 1 are driven away from each other, and the two locking frames 1 can be completely opened to facilitate the repair of the shaft.
