[0002] A wind turbine generally consists of wind turbine blades, an electrical control cabinet, a gearbox and support columns. The kinetic energy of the wind is converted into mechanical energy of the wind turbine blades, which drives the gearbox in the electrical control cabinet to rotate, and then generates electricity after the gearbox increases the speed.
[0003] Existing wind turbines typically feature stoppers at the blades to prevent them from falling. When the wind is light, the blades rotate slowly, and the stoppers still come into contact with them, causing accelerated wear. In stronger winds, the stoppers alone are ineffective, requiring additional braking devices to slow the fan blades. Adding external braking devices to work with the stoppers requires additional mounting locations, making installation inconvenient. Summary of the Invention

DETAILED DESCRIPTION
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention, so as to have a further understanding of the concept of the present invention, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.
[0024] like Figures 1-8 As shown, a wind-resistant and fall-proof wind power generation device includes a support column 1, an electric control cabinet 2 and a gearbox 3, including wind turbine blades 4, a circular mounting block 5, a limit assembly 6 and a brake assembly 7; The wind turbine blades 4 are arranged at equal intervals along the circumference of the circular mounting block 5; The circular mounting block 5 is mounted on the bearing of the gearbox 3. A mounting groove 51 is defined in the circular mounting block 5. The mounting groove 51 is L-shaped and includes a radial groove and an axial groove. A through hole 52 is defined on the surface of the circular mounting block 5 so that air can enter the mounting groove 51 through the through hole 52. The limiting assembly 6 is arranged in the radial groove and passes through the side wall of the circular mounting block 5. The wind blows the limiting assembly 6 upward along the radial groove and presses against the bearing of the gearbox 3; The brake assembly 7 is arranged at the end of the axial groove and passes through the side wall of the circular mounting block 5. The wind blows the brake assembly 7 to move rightward along the axial groove and presses against the side wall of the electric control cabinet 2 to brake.
[0025] When using this device, the support column 1, the electrical control cabinet 2, the gearbox 3 and the wind turbine blade 4 are installed to carry out normal wind power generation operations; the circular mounting block 5 is arranged on the bearing of the gearbox 3. When the wind is small, the brake assembly 7 and the limit assembly 6 are respectively in the axial groove and the radial groove, and do not contact other components and will not be damaged; when the wind is strong, the wind enters the mounting groove 51 through the through hole 52 of the circular mounting block 5; the wind blows the limit assembly 6 upward in the radial groove, and the limit assembly 6 is pressed against the bearing of the gearbox 3 for limiting, thereby improving the fixation of the device; the wind blows the brake assembly 7 to move to the right in the axial groove, and presses against the side wall of the electrical control cabinet 2 for braking, which reduces the rotation speed of the wind turbine blade 4 when the wind is strong and improves the stability of the device; when not in use, the limit assembly 6 and the brake assembly 7 are also arranged in the mounting groove 51, which will not affect the normal operation of the device.
[0026] like Figure 2As shown in the figure, as a preferred embodiment, the circular mounting block 5 is provided with multiple mounting slots 51 and through-holes 52 matching the mounting slots 51; the number of limit assemblies 6 and brake assemblies 7 matches the number of mounting slots 51. In this embodiment, the multiple mounting slots 51 and through-holes 52 provided on the circular mounting block 5 increase the air intake channel. Each limit assembly 6 and brake assembly 7 can be used independently, or multiple limit assemblies 6 and brake assemblies 7 can work together to enhance the limiting and braking effects.
[0027] like Figure 3-Figure 5 As shown, as a preferred embodiment, the limit assembly 6 includes a movable block 61, a push rod 62, a constraint rod 63 and a first constraint cylinder 64; the push rod 62 is vertically arranged in the radial groove, and the movable block 61 is arranged on the upper part of the push rod 62; the left part of the movable block 61 passes through the side wall of the circular mounting block 5, and is vertically arranged to press against the bearing of the gearbox 3, and the right part of the movable block 61 is provided with a vertical mounting hole 65, the top of the constraint rod 63 is connected to the top of the radial groove, and the lower end is connected to the mounting hole 65, and the first constraint cylinder 64 is sleeved on the outer wall of the constraint rod 63, one end presses against the top of the radial groove, and the other end presses against the upper part of the movable block 61; the wind blows the push rod 62 upward, driving the left part of the movable block 61 to press against the bearing of the gearbox 3 for fixation. In this embodiment, when the limiting assembly 6 is required to operate, the wind blows the bottom of the push rod 62, driving the push rod 62 to move upward. The movable block 61 is installed on the top of the push rod 62 and moves upward with the push rod 62. The left end of the movable block 61 passes through the radial groove and is limited by pressing against the bearing of the gearbox 3 to prevent the circular mounting block 5 from separating from the gearbox 3, thereby achieving stability of the wind turbine blade 4. A mounting hole 65 is provided on the right side of the movable block 61. During the upward movement of the movable block 61, the top right side of the movable block 61 squeezes the first constraint cylinder 64, and the first constraint cylinder 64 is squeezed and contracted along the constraint rod 63. When the wind force is weak, the first constraint cylinder 64 recovers its deformation and drives the movable block 61 downward. The left side of the movable block 61 also moves downward to reset, and does not contact the bearing of the gearbox 3, thereby preventing wear.
[0028] like Figure 4 As shown, as a preferred embodiment, the first constraint cylinder 64 is a first spring cylinder with a W-shaped cross section. In this embodiment, the first constraint cylinder 64 is set in the form of a first spring cylinder, and the elastic potential energy is better released by the spring to help the device reset.
[0029] like Figure 6As shown, as a preferred embodiment, the brake assembly 7 includes a push block 71, a second spring 72, a wear-resistant block 73 and a limiting rod 74; the push block 71 is arranged in the axial groove and is connected to the wear-resistant block 73 through the second spring 72, and the wear-resistant block 73 extends out of the circular mounting block 5 and presses against the side wall of the electric control cabinet 2; the push block 71 is circular and has a plurality of limiting through holes 75 along the circumference, the limiting rod 74 is horizontally arranged, one end is connected to the limiting through hole 75, and the other end is connected to the side wall of the axial groove, and a second constraint cylinder 76 is sleeved on the limiting rod 74, and the second constraint cylinder 76 is sleeved on the outer wall of the limiting rod 74, one end presses against the push block 71, and the other end presses against the side wall of the axial groove. In this embodiment, when brake assembly 7 is required to operate, wind pushes push block 71 rightward. Push block 71 then drives wear block 73 rightward via second spring 72. As wear block 73 continues its rightward movement, extending from its axial slot, its sidewall contacts the sidewall of electrical cabinet 2, increasing friction and applying braking and deceleration. Because push block 71 compresses second restraining cylinder 76 during its rightward movement, at lower wind speeds, second restraining cylinder 76 recovers its deformation and moves leftward, driving wear block 73 and push block 71 to reset. At this point, wear block 73 no longer contacts the sidewall of electrical cabinet 2, preventing wear.
[0030] like Figure 6 As shown, as a preferred embodiment, the second restraining cylinder 76 is a third spring cylinder with a W-shaped cross-section. This configuration allows for better release of elastic potential energy through the spring, assisting in the device's reset. In a preferred embodiment, multiple second restraining cylinders 76 can be provided, along with multiple limiting through-holes 75, to enhance the device's reset performance.
[0031] like Figure 7 and Figure 8 As shown, as a preferred embodiment, it also includes an adjustment component 8, which includes a motor 81 and an adjustment shaft 82; the motor 81 is arranged on the side wall of the circular mounting block 5, and the output shaft of the motor 81 passes through the circular mounting block 5 and extends into the mounting groove 51 to be connected to the adjustment shaft 82; the adjustment shaft 82 is hollow, and an air duct bin 83 is formed inside. The side wall of the adjusting shaft 82 is provided with three ventilation slots 84 at equal intervals along the circumferential direction, and the ventilation slots 84 are connected to the air duct bin 83, and the size matches the through hole 52; the adjusting shaft 82 is also provided with a first connecting slot 85, a second connecting slot 86 and a third connecting slot 87 on the inner side wall along the axial direction; the first connecting slot 85 is horizontally arranged, the left end is closed, the middle part is connected to the air duct bin 83, and the right end is connected to the brake component 7; the second connecting slot 86 is horizontally arranged, the left end is connected to the limit component 6, the middle part is connected to the air duct bin 83, and the right end is closed; the third connecting slot 87 is horizontally arranged, the left end is connected to the limit component 6, the middle part is connected to the air duct bin 83, and the right end is connected to the brake component 7.
[0032] In this embodiment, the opening size of the ventilation slot 84 matches the through hole 52, and the air inlet is adjusted by the adjustment component 8. An adjustment shaft 82 is set in the mounting slot 51, and the wind enters the air duct bin 83 from the through hole 52 and the ventilation slot 84 on the circular mounting block 5. When braking and anti-falling are required, but the wind force is not so strong, the motor rotates 81 to connect the first connecting slot 85 or the second connecting slot 86 to the air duct bin 83. When the first connecting slot 85 is ventilated, the blowing limit component 6 is pressed upward against the bearing of the gearbox 3 for limiting; when the second connecting slot 86 is ventilated, the blowing brake component 7 is pressed to the right against the side wall of the electric control cabinet 2 for braking. The two devices can also work in turn to avoid wear. When the wind is too strong, the motor 81 rotates to connect the third connecting groove 87 to the air duct bin 83. At this time, the limit assembly 6 and the brake assembly 7 work at the same time, which increases the limit braking effect. The operating device is adjusted by adjusting the adjustment assembly 8. The limit assembly 6 and the brake assembly 7 work in turn or at the same time, preventing excessive wear while ensuring safety.
