The vertical plates 3 are provided at both ends of the top of the base plate 1. The extension plate 4 is connected to the inner side of the top of the vertical plate 3. The upper arc block 5 is fixed to the bottom of the extension plate 4 by a second connecting bolt 10. The lower end of the upper arc block 5 is provided with a lower arc block 6;

[0024] A servo motor 11 is provided at the top of the base plate 1 near the center through a fixed seat, and a screw rod 12 is connected to the power output end of the servo motor 11. A bearing 22 is provided on the outer periphery of the top of the screw rod 12, and the top of the bearing 22 is connected to the bottom of the lower arc block 6. A wire block 13 is sleeved on the outside of the screw rod 12, and a limiting guide rail 14 is provided on the inner side of the two groups of vertical plates 3. The two ends of the wire block 13 are respectively located in the corresponding limiting guide rails 14, and the first connecting plate 18 and the second connecting plate 19 are respectively provided at the connection between the upper arc block 5 and the lower arc block 6. Guide rods 20 are provided on both sides of the bottom of the first connecting plate 18, and guide grooves 21 are opened on both sides of the top of the second connecting plate 19, and the guide rods 20 pass through the corresponding guide grooves 21.

[0025] During use, the servo motor 11 can conveniently drive the screw 12 to rotate when working. When the screw 12 rotates, it drives the wire block 13 to rise and fall along the limiting guide rail 14, thereby driving the bearing 22 and the lower arc block 6 to rise and fall. The input shaft end of the wind turbine is located between the upper arc block 5 and the lower arc block 6. When the upper arc block 5 is close to the lower arc block 6, the brake pad 8 is used to brake the input shaft of the generator. The guiding effect of the limiting guide rail 14 on the wire block 13 and the guiding effect of the guide groove 21 on the guide rod 20 can effectively improve the stability of the lower arc block 6 during movement. The braking mechanism has a simple structure and the braking mechanism has a guiding structure when moving. It has good stability when in contact with the rotating shaft of the wind turbine and has a better braking effect.

[0026] For example, Figure 1 and Figure 3 As shown, the utility model also includes that a brake pad 8 is provided on the inner wall of the lower arc block 6, and an arc-shaped connecting block 9 is provided on one side of the brake pad 8, and the arc-shaped connecting block 9 is connected and fixed to one side of the lower arc block 6 by a first connecting bolt 7.

[0027] When in use, the arc-shaped connecting block 9 is conveniently connected to one side of the lower arc-shaped block 6 through the first connecting bolt 7 , thereby fixing the brake pad 8 on the inner side of the lower arc-shaped block 6 .

[0028] For example, Figure 1-3 As shown, the present invention further includes that a PLC controller 16 is mounted on one side of the mounting plate 17 through a fixing groove, and the output end of the PLC controller 16 is electrically connected to the input end of the servo motor 11 through a wire.

[0029] When in use, personnel can control the PLC controller 16 to conveniently control the operation of the servo motor 11 .

[0030] For example, Figure 1-3 As shown, the present invention further includes a reinforcing plate 15 provided at the corner where the bottom end of the vertical plate 3 is connected to the top of the bottom plate 1 .

[0031] During use, the reinforcing plate 15 can effectively improve the overall strength of the vertical plate 3 and the bottom plate 1 after they are connected.

[0035] During use, the brake pad 8 made of polyetheretherketone material has good wear resistance and high temperature resistance and a long service life.

[0036] When the utility model is in use, the brake pad 8 made of polyetheretherketone material has good wear resistance and high temperature resistance and a long service life. The external bolt passes through the mounting hole 2, which is convenient for fixing and installing the brake mechanism. The reinforcing plate 15 can effectively improve the overall strength of the vertical plate 3 and the bottom plate 1 after connection. The personnel can control the operation of the servo motor 11 by controlling the PLC controller 16.

[0037] When working, the servo motor 11 can conveniently drive the screw rod 12 to rotate. When the screw rod 12 rotates, it drives the wire block 13 to rise and fall along the limiting guide rail 14, thereby driving the bearing 22 and the lower arc block 6 to rise and fall. The input shaft end of the wind turbine is located between the upper arc block 5 and the lower arc block 6. When the upper arc block 5 and the lower arc block 6 are close to each other, the brake pad 8 is used to brake the input shaft of the generator. The guiding effect of the limiting guide rail 14 on the wire block 13 and the guiding effect of the guide groove 21 on the guide rod 20 can effectively improve the stability of the lower arc block 6 during movement.
