[0026] A plurality of fixed frames 4 are fixed on the guardrail 3 at equal intervals, and a support plate 5 is connected to the fixed frame 4 through a rotating shaft. The support plate 5 is provided with two symmetrically distributed slide grooves 13, and a fixed plate 14 is fixed to the bottom of the support plate 5. Two symmetrically distributed guide rods 15 are passed through the fixed plate 14, and a U-shaped frame 17 is fixed to one end of the two guide rods 15, and a movable plate 16 is fixed to the other end. The outer walls of the two guide rods 15 are sleeved with return springs 20, and the return springs 20 are located between the fixed plate 14 and the movable plate 16. A movable rod 12 is fixed to the top of the movable plate 16 and inside the two slide grooves 13. A mounting plate 18 is fixed to the top of the two movable rods 12. A pull rod 19 is connected to the mounting plate 18 through a rotating shaft, and the movable rod 12 has the freedom to move along the length of the slide groove 13. When in use, first, when the maintenance personnel climb upwards, the maintenance personnel can pull the pull rod 19 and use the rotating shaft to flip the support plate 5, and at the same time, the pull rod 19 can also be moved by The pivot shaft rotates on the mounting plate 18, thereby driving the moving rod 12 to move inside the slide groove 13. Since the moving rod 12 is fixedly connected to the moving plate 16, the movement of the moving rod 12 will drive the moving plate 16 and the guide rod 15 to move. In this process, the return spring 20 will be compressed to provide elastic support for the movement of the moving plate 16. Subsequently, the U-shaped frame 17 is hung on the guardrail 3 to fix the support plate 5. When the maintenance personnel climb up a certain distance each time, they can pull the pull rod 19 and flip the support plate 5 to fix it, thereby reducing the climber's fear and further reducing the risk of climbing. When the maintenance personnel climb down, they can pull the pull rod 19 upward and then release the pull rod 19. At this time, the return spring 20 will return to its original state, pushing the moving plate 16 and the U-shaped frame 17 back to the initial position. In this process, the support plate 5 will be flipped by the pivot shaft, which is convenient for the maintenance personnel to climb down, thereby improving the convenience and safety during use.

[0027] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6, a plurality of first connecting rods 6 are passed through the position of the top surface of the support plate 5 away from the slide groove 13, and a plurality of second connecting rods 10 are passed through the position of the top surface of the support plate 5 close to the slide groove 13. A first protective plate 7 is fixed to the top of the plurality of first connecting rods 6, and a nut is installed at the bottom through a thread. One side of the first protective plate 7 is connected to the second protective plate 9 through a hinge. The top ends of the plurality of second connecting rods 10 are fixed with a top plate 11, and a nut is installed at the bottom through a thread. The outer wall of the first connecting rod 6 is provided with a buffer spring 8, and the buffer spring 8 is located between the first protective plate 7 and the support plate 5. The outer wall of the second connecting rod 10 is provided with a buffer spring 8, and the buffer spring 8 is located between the top plate 11 and the support plate 5; when in use, the second protective plate 9 can be flipped over by the hinge so that it is located above the top plate 11, so that the first protective plate 7 and the second protective plate 9 can be buffered by the buffer spring 8, thereby improving the protective effect of the first protective plate 7 and the second protective plate 9.

[0028] Reference Figure 3 and Figure 5 The top of the top plate 11 and the bottom of the second protective plate 9 are both provided with anti-slip grooves to increase the anti-slip performance and improve the safety of work.

[0029] Reference Figure 3 The outer wall of the pull rod 19 is provided with anti-slip grooves, which makes it convenient for maintenance personnel to pull the pull rod 19.

[0030] Reference Figure 2 Anti-skid stripes are arranged on both sides of the straight ladder 2 to improve the anti-skid performance of the workers during the climbing process and increase work safety.

[0031] Reference Figure 2 The guardrail 3 is made of high-strength material; it can withstand greater impact force and effectively prevent workers from accidentally falling.

[0032] Reference Figure 3 The first protective plate 7 and the second protective plate 9 are made of lightweight materials; they can provide sufficient protection, reduce the weight of the entire device, and facilitate the installation and flipping of the support plate 5.

[0033] The implementation principle of a safety protection device for wind power generation installation in an embodiment of the present application is as follows: when in use, first, when the maintenance personnel climb upward, they can pull the pull rod 19 and use the rotating shaft to flip the support plate 5. At the same time, the pull rod 19 can also be rotated on the mounting plate 18 through the rotating shaft, thereby driving the moving rod 12 to move inside the slide groove 13. Since the moving rod 12 is fixedly connected to the moving plate 16, the movement of the moving rod 12 will drive the moving plate 16 and the guide rod 15 to move. In this process, the return spring 20 will be compressed to provide elastic support for the movement of the moving plate 16. Then the U-shaped frame 17 is hung on the guardrail 3 to fix the support plate 5. After the maintenance personnel climb up a certain distance, they can fix it by pulling the pull rod 19 and flipping the support plate 5, thereby reducing the climber's fear and further reducing the danger of climbing.

[0034] When the maintenance personnel climb down, they can pull the pull rod 19 upwards and then release the pull rod 19. At this time, the reset spring 20 will return to its original state, pushing the movable plate 16 and the U-shaped frame 17 back to the initial position. In this process, the support plate 5 will be flipped using the rotating shaft, thereby facilitating the maintenance personnel to climb down and improving the convenience and safety of use.
