[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0023] Please see Figures 1 to 3 A wind turbine generator tower platform cover plate includes a tower body 9 and a tower platform body 5. The tower platform body 5 is fixedly connected to the inner side of the tower body 9. A vertical groove 10 is provided through the top of the tower platform body 5. An opening 11 is provided through the side of the tower platform body 5 near the vertical groove 10. The opening 11 is connected to the vertical groove 10. The opening 11 facilitates workers to pass through and climb. Two vertical rods 3 are fixedly connected to the inner side of the vertical groove 10.

[0024] Multiple climbing poles 4 are fixedly connected between the two vertical poles 3 to facilitate climbing. A sealing cover 2 is set above the opening 11. A horizontal groove 1 is set on the top of the tower platform body 5. A driving component is set inside the horizontal groove 1. A connecting component is set on one side of the sealing cover 2. Two fixing blocks 7 are symmetrically fixedly connected to the top of the tower platform body 5. A sliding groove 12 is opened on the opposite side of the two fixing blocks 7. A slider 6 is slidably connected inside the two sliding grooves 12. One side of the two sliders 6 is fixedly connected to one side of the sealing cover 2. By sliding the sliders 6 inside the sliding grooves 12, the movement stability of the sealing cover 2 is improved.

[0025] like Figure 1 and Figure 3 As shown, the drive assembly includes a screw 8, one end of which is rotatably connected to the inside of the transverse groove 1. A motor is fixedly connected to the inside of the transverse groove 1, and the output end of the motor is fixedly connected to one end of the screw 8. A drive block 14 is threadedly connected to the outside of the screw 8. The outside of the drive block 14 is slidably connected to the inside of the transverse groove 1. The drive assembly facilitates the opening and closing of the sealing cover 2.

[0026] like Figure 1 and Figure 4As shown, the connecting assembly includes a connecting plate 19. One side of the connecting plate 19 is fixedly connected to one side of the sealing cover 2. A rod 18 is slidably connected through the connecting plate 19. A lifting plate 15 is fixedly connected to the top of the rod 18. A limiting plate 17 is sleeved on the outside of the rod 18 and is located below the connecting plate 19. A spring 16 is sleeved on the outside of the rod 18. The connecting assembly facilitates the connection and fixation between the sealing cover 2 and the driving block 14. The two ends of the spring 16 are fixedly connected to the top of the connecting plate 19 and the bottom of the lifting plate 15, respectively. The top of the driving block 14 is provided with an insertion hole 13. The bottom end of the rod 18 is installed inside the insertion hole 13. The limiting plate 17 is installed on the top of the driving block 14 and fits against it, which facilitates the connection between the sealing cover 2 and the driving block 14.

[0027] In use, when workers climb the climbing pole 4, the motor (which can be controlled wirelessly) is activated, driving the screw 8 to rotate. The rotating screw 8 moves the drive block 14, which in turn moves the sealing cover 2, opening the passage 11 and facilitating continued climbing. After the worker completes the climb, protection is needed. The motor is activated to reverse the screw 8, moving the drive block 14 in the opposite direction and closing the passage 11. This allows workers to work on the tower while preventing accidental falls from the through-frame. In case of a power outage, the lifting plate 15 compresses the spring 16, separating the bottom of the rod 18 from the insertion hole 13. This separates the sealing cover 2 from the drive block 14, allowing the slider 6 to slide within the groove 12 and open the sealing cover 2, preventing workers from being trapped and ensuring their normal work.
