In order to ensure the normal operation of equipment, industrial workers need to climb the tower for high altitude operation during maintenance or repair, and power construction personnel often need to carry out power construction repair. During the maintenance process, the construction personnel need to carry out high altitude operation, so the operating personnel face a high risk of falling. Once a falling accident occurs, it will seriously threaten the life safety of the operating personnel. The anti-falling device is designed for high altitude operation and has multiple protection mechanisms. It can quickly start and play a role when the operating personnel falls, providing reliable protection for the operating personnel.

[0034] The electromagnet 10 is installed at the bottom of the unmanned aerial vehicle. The magnetic plate 7 is attracted by the electromagnet 10. The unmanned aerial vehicle is started. The magnetic plate 7 and the movable rod 6 are lifted by the electromagnet 10. The locking block 13 moves into the accommodating groove. The locking block 13 and the vertical column 1 are limited to drive the whole device to rise to the top of the power tower (or other positions of the power tower). In order to facilitate understanding, the top of the power tower is taken as an example for use description. At this time, the support two 4 is subjected to gravity, and the opening thereof faces downward. The unmanned aerial vehicle is operated to hang the opening of the support two 4 on the power tower. Then the whole device is moved downward. The support two 4 is limited by the power tower and rotates along the axis of the rotating shaft 5 to form a relatively closed rectangular structure with the support one 2. After the hanging is completed, the electromagnet 10 is turned off to realize the separation of the device and the unmanned aerial vehicle. The magnetic plate 7 is lowered by gravity after the separation, so that the locking block 13 moves into the avoiding groove 14 to lock the movable rod 6 and prevent shaking.

[0035] The support one 2, the support two 4, the magnetic plate 7 and the electromagnet 10 are arranged. The device and the power tower can be connected by the unmanned aerial vehicle under the magnetic attraction of the magnetic plate 7 and the electromagnet 10. The operation personnel do not need to climb to connect, so that the operation convenience and the operation safety are improved.

[0038] After the movable rod 6 and the locking block 13 are inserted into the avoiding groove 14, the spring 15 is elastically deformed under the force. Then the movable rod 6 is rotated to move the locking block 13 into the arc-shaped locking groove 12. The spring 15 pushes the locking block 13 to make the contact between the arc-shaped locking groove 12 and the locking block 13 more closely.

[0039] The arc-shaped locking groove 12 can lock the locking block 13 to lock the support two 4 and the movable rod 6. The safety of the device is further improved.

[0040] AsFigure 2 As shown, the outer wall of the electromagnet 10 is provided with a spline 9, and the top of the magnetic plate 7 is provided with a key groove 8 matched with the spline 9.

[0041] Insert the spline 9 on the electromagnet 10 into the key groove 8, turn on the electromagnet 10, and make the magnetic plate 7 and the electromagnet 10 attract each other. Push the magnetic plate 7 and the movable rod 6 downward by using the electromagnet 10, and move the locking block 13 into the avoiding groove 14 along with the movable rod 6. Then, operate the unmanned aerial vehicle to rotate it, drive the magnetic plate 7 and the movable rod 6 to rotate by using the electromagnet 10, and rotate the locking block 13 into the arc-shaped locking groove 12 along with the movable rod 6, so as to complete the locking of the bracket two 4 and the movable rod 6. When it is needed to be unlocked, reverse the above steps.
