[0034] See also Figure 3 The inner bracket 2 is a rectangular metal frame structure in a top view, and its thickness is the same as that of the outer shell 1, and its width is slightly smaller than that of the outer shell 1, so as to ensure that it can be smoothly installed inside the outer shell 1. There are four connecting holes C 23 on the left side plate 21 of the inner bracket and the right side plate 22 of the inner bracket for connecting the inner bracket 2 with the outer shell 1. There is an inner bracket rectangular hole 24 in the middle of the right side plate 22 of the inner bracket, and the size of the inner bracket rectangular hole 24 can ensure that the short side pressing piece 33 of the rotating pressing piece 3 can pass smoothly.

The connecting plate 35 is located between the short side pressing sheet 33 and the long side pressing sheet 34, and is used to strengthen the mechanical properties of the overall structure.

[0036] See also Figure 5 The rope clamping mechanism 4 is an L-shaped structure, consisting of a long plate 41 and a short plate 42. The top of the long plate 41 has a rope clamping mechanism through hole A43, which is used to achieve axial connection with the connecting hole B19 at the bottom of the housing 1. The bottom of the short plate 42 has a rope clamping mechanism through hole B44, whose diameter is larger than the diameter of the safety ball 7, which can ensure that the safety ball 7 passes smoothly.

When the safety ball 7 passes from the bottom to the top from the bottom of the rope clamping mechanism 4 driven by the traction rope 8, the hinge 52 can ensure that the safety ball 7 can smoothly lift the U-shaped baffle 51 and pass through.

[0038] See also Figure 7 The protective shell 6 is composed of a protective shell top plate 61, a protective shell front plate 62, a protective shell rear plate 63 and a protective shell side plate 64.

There is a protective shell rectangular hole A65 at the lower right corner of the protective shell front plate 62, and the remaining position is used for the installation of the hinge 52. There is a protective shell rectangular hole B66 at the upper right corner of the protective shell rear plate 63, which is used for the passage of the safety ball 7, the traction rope 8 and the safety rope 9. There is a pair of axial holes B67 at the top positions of the protective shell front plate 62 and the protective shell rear plate 63, which are used to realize axial connection with the connecting hole B19 of the outer shell 1.

[0039] See also Figure 8 The safety ball 7 is a spherical structure. The safety ball has a countersunk threaded hole 71 in the horizontal direction for installing a double rope connecting bolt 72. The safety ball has a keyway hole 73 running through it in the vertical direction.

[0040] The working principle of the present invention is:

[0041] See also Figure 1 When deploying the climbing protection device, the traction rope 8 is passed through the through hole B 44 on the short plate of the rope clamping mechanism and the rectangular hole B 66 of the protective shell on the rear plate of the protective shell. The drone flies to the top of the iron tower by carrying the climbing protection device and the traction rope 8 through the lifting ring. As the drone rises, the middle position of the traction rope 8 is lifted, and the two ends of the traction rope 8 are vertical to the ground. The operator controls the drone so that the angle iron at the edge of the iron tower is located between the left side plate 12 and the right side plate 13 of the outer shell of the climbing protection device, and slowly lowers the height of the drone.

[0042] The drone drives the climbing protection device to descend. When the bent pressing piece 32 in the rotating pressing piece 3 first contacts the top of the angle iron, as the drone continues to descend, the bent pressing piece 32 encounters the resistance of the angle iron, and the movable short side pressing piece 33 and the long side pressing piece 34 of the rotating pressing piece 3 begin to rotate, and the short side pressing piece 33 passes through the inner bracket rectangular hole 24 and the outer shell rectangular hole 15 in sequence. The drone continues to descend. When the proximal end of the bent pressing piece 32 rotates to nearly horizontal, the short side pressing piece 33 completely enters the interior of the inner bracket 2, and the long side pressing piece 34 rotates to contact the bottom surface of the angle iron and maintains a horizontal state. The drone continues to descend, and the inner bracket 2 stops moving downward under the support of the angle iron. The outer shell 1 continues to descend under the constraint of the sliding groove 14. The top of the inner bracket 2 coincides with the lower surface of the outer shell top plate 11, realizing the automatic locking of the climbing protection device and the angle steel at the top of the tower.

[0043] When the climbing protection device is automatically locked, one end of the safety rope 9 is passed through the lower half of the safety ball key slot hole 73 and fixed to the connecting bolt 72; one end of the traction rope 8 is passed through the safety ball key slot hole.
