Two second grooves 203b are provided on the inner side wall of the connecting seat 203a. A first spring 203c is fixedly connected to the lower wall of each of the two second grooves 203b, and a connecting block 203d is fixedly connected to one side of the first spring 203c; wherein, the connecting block 203d is slidably connected to the second groove 203b; the lifting assembly 204 includes a lifting seat 204a provided in the connecting seat 203a.

A second inclined surface 204d is provided on the side wall of the pushing block 204c. A limiting plate 204e is fixedly connected to the lower side of the lifting seat 204a. A connecting groove 204f is provided on the upper side of the card rail 102; wherein, the side wall of the lifting seat 204a is fixedly connected to the connecting block 203d.

[0040] Specifically, there are two first chutes 202a, and the two first chutes 202a are symmetrically arranged. The first sliding plate 202b is arranged in a U shape. The fixed block 202c serves to prevent the first sliding plate 202b from sliding out of the fixed card slot through the first chute 202a. There are two connecting assemblies 203 and two lifting assemblies 204, and the two connecting assemblies 203 and the two lifting assemblies 204 are both symmetrically arranged. The lower sides of the two lifting seats 204a are commonly fixedly connected to the limiting plate 204e. The connecting seat 203a is fixedly connected to the inner side wall of the fixed card seat 201a. The connecting seat 203a is arranged in a U shape. The two second grooves 203b are symmetrically arranged. The lifting seat 204a is slidably connected to the connecting seat 203a. The first inclined surface 204b is adapted to the second inclined surface 204d. The limiting plate 204e is slidably connected to the connecting groove 204f. When the first sliding plate 202b moves backward, the pushing block 204c will squeeze the lifting seat 204a, causing the lifting seat 204a to drive the limiting plate 204e to move downward under the action of the first inclined surface 204b and the second inclined surface 204d, so that the limiting plate 204e restricts the rivet 103.

[0041] Furthermore, the limiting assembly 205 includes a fixed slide 205a arranged on the inner side wall of the fixed clamping seat 201a, a slide column 205b is provided on the fixed slide 205a, the side wall of the slide column 205b is fixedly connected to the limiting plate 205c, and the side wall of the slide column 205b is provided with a sliding groove 205d; wherein the sliding groove 205d is slidably connected to the slide; the guiding assembly 206 includes a connecting plate 206a arranged on the side wall of the lifting seat 204a, the side wall of the connecting plate 206a is provided with a guide groove 206b, the inner side wall of the guide groove 206b is provided with a first arc surface 206c, the inner side wall of the guide groove 206b is provided with a second arc surface 206d, and the side wall of the limiting plate 205c is fixedly connected to a guide column 206e; wherein the guide column 206e is slidably connected to the guide groove 206b.

The connecting plate 206a is fixedly connected to the lifting seat 204a, the connecting plate 206a is L-shaped, and the guide groove 206b is an oblique groove, so that when the connecting plate 206a moves with the lifting seat 2 04a moves downward, the guide column 206e will move away from the lifting seat 204a under the action of the guide groove 206b, and when the guide column 206e contacts the second arc surface 206d, the limiting plate 205c limits the first bolt 201f. When the guide column 206e contacts the first arc surface 206c, the limiting plate 205c does not contact the first bolt 201f. At this time, the limiting plate 205c is not limited by the first bolt 201f, and at the same time will not affect the fixed connection between the fixed base 201a and the back plate 101 through the first bolt 201f.

[0043] When in use, in conjunction with the embodiment, after the fixed base 201a restricts the pitch PLC, it pushes the first slide plate 202b backward, and the pushing block 204c moves backward with the first slide plate 202b. When the pushing block 204c moves backward, it will squeeze the lifting seat 204a. The lifting seat 204a is squeezed and moves downward under the action of the first inclined surface 204b, the second inclined surface 204d, the connecting block 203d and the second groove 203b, so that the limiting plate 204e moves downward with the lifting seat 204a, so that the limiting plate 204e contacts the front side of the rivet 103, so that the limiting plate 204e limits the rivet 103, effectively preventing the rivet 103 from loosening, and when the lifting seat 204a moves downward, the connecting plate 206a will move with the lifting seat 204 a moves downward, at this time, the guide column 206e will drive the limit plate 205c to move in the direction of the second arc surface 206d under the action of the guide groove 206b. At the same time, the limit plate 205c will move away from the lifting seat 204a and contact the first bolt 201f as the guide column 206e moves under the action of the sliding column 205b, the sliding groove 205d and the fixed sliding seat 205a, thereby limiting the first bolt 201f and effectively preventing the first bolt 201f from loosening, further reducing the possibility of the variable pitch PLC body 104 falling, and further avoiding the falling variable pitch PLC body 104 from affecting the normal operation of the variable pitch system due to collision and damage with other equipment in the hub variable pitch control cabinet, thereby indirectly improving the reliability and operation efficiency of the wind turbine.

[0044] In summary, through the cooperation of the sliding assembly 202, the connecting assembly 203, the lifting assembly 204, the limiting assembly 205 and the guiding assembly 206, the rivet 103 and the first bolt 201f can be effectively limited to prevent the rivet 103 and the first bolt 201f from loosening, thereby further reducing the possibility of the variable pitch PLC body 104 falling.

[0050] When in use, in conjunction with Example 1 and Example 2, when the first slide plate 202b moves backward, the L-shaped plate 302e will move backward with the first slide plate 202b. At this time, the L-shaped plate 302e will squeeze the upper squeezing plate 302c, and the upper squeezing plate 302c will drive the rotating column 302b and the lower squeezing plate 302d to deflect counterclockwise with the rotating column 302b as the center, so that the lower squeezing plate 302d squeezes the movable plate 301c, so that the second anti-wear and flame-retardant belt 301d contacts the variable pitch PLC body 104, so as to restrict the variable pitch PLC body 104 between the movable plate 301c and the fixed bracket 201a, further restrict the variable pitch PLC body 104, play a role of reinforcement, further suppress the shaking of the variable pitch PLC body 104, and further reduce the falling of the variable pitch PLC body 104 The possibility of the pitch PLC body 104 falling and colliding with other equipment in the hub pitch control cabinet to be damaged and affect the normal operation of the pitch system, further indirectly improve the reliability and operation efficiency of the wind turbine, and then, the second bolt 303j is fixed to the protrusion 303i to fix the first slide plate 202b to the fixed bracket 201a, to avoid the displacement of the first slide plate 202b and affect the limiting reinforcement effect, and the reinforcement bracket 303c is connected to the second slot 303f through the first clamping block 303d. When the first clamping block 303d is inserted into the first slot 303e, the second clamping block 303g is connected to the first slot 303e, so that the reinforcement bracket 303c limits the second bolt 303j to prevent the second bolt 303j from loosening, and effectively prevents the displacement of the first slide plate 202b.

[0051] In summary, in combination with Example 1 and Example 2, and through the cooperation of the moving component 301, the extrusion component 302 and the reinforcement component 303, the variable pitch PLC body 104 can be further restricted, and the position of the first slide plate 202b can be fixed to prevent the first slide plate 202b from being displaced, thereby achieving the effect of further reducing the possibility of the variable pitch PLC body 104 falling.
