However, there are still some people with poor safety awareness who will try to climb the power tower.

[0003] In order to deal with this challenge, the industry generally adopts measures such as setting up fences, installing video monitoring systems, and installing alarm devices to improve the safety level of the tower area; in addition, a more common method is to install spikes at the bottom of the tower or to coat with smooth paint to increase the climbing difficulty.

[0004] Setting up fences can effectively isolate external interference, but the occupied area is large, the construction difficulty is high, and the long-term maintenance cost is also not low; installing a video monitoring system can monitor the site in real time and timely detect abnormalities, but is easily affected by environmental factors, has low recognition rate at night, and has huge investment; installing an alarm device can issue a warning when detecting that someone tries to approach, which has a certain deterrent effect, but has a high false alarm rate, and lacks a follow-up disposal mechanism once the alarm is triggered; installing spikes at the bottom of the tower or coating with smooth paint can delay the climbing speed to a certain extent, but it is still feasible for professional climbers.

[0038] Reference Figure 2 The linkage group 2221 is provided with two groups along the width direction of the auxiliary ladder 221, one end of the linkage group 2221 is fixedly connected with the tower body 1, the other end of the linkage group 2221 is fixedly connected with the auxiliary ladder 221, the rectangular linkage mechanism 222 further comprises a transmission shaft 2223, both ends of the transmission shaft 2223 are fixedly connected with the two groups of linkage groups 2221, and the two groups of linkage groups 2221 are synchronously folded and unfolded through the transmission shaft 2223.

[0039] With reference to Figure 2 The linkage 2221 includes a first rocker 22211, the driving device 2222 is a stepper motor, the first rocker 22211 is fixedly connected with an output shaft of the stepper motor, the linkage 2221 further includes a fixed rod 22212, the fixed rod 22212 is fixedly connected with the sub-ladder 221, the linkage 2221 further includes a second rocker 22213, the second rocker 22213 supports the fixed rod 22212 to move together with the first rocker 22211, and the fixed rod 22212 drives the sub-ladder 221 to move up / down.

[0044] With reference to Figure 1The card swiping device 2225 is arranged on one side of the stepping motor, and the card swiping device 2225 and the stepping motor are connected to the PLC controller. The identity information is pre-stored in the PLC controller. When the worker needs to climb the tower body 1 for maintenance, the identity card can be inserted into the card swiping device 2225 to identify the identity information of the worker through the card swiping device 2225. The card swiping device 2225 transmits the identity information of the worker to the PLC controller in real time. The PLC controller compares the received identity information with the pre-stored identity information in the PLC controller. If the received identity information is consistent with the pre-stored identity information in the PLC controller, the stepping motor is controlled to start to drive the auxiliary ladder 221 to rotate between the first climbing main ladder 21 and the second climbing main ladder 23 to connect the first climbing main ladder 21 and the second climbing main ladder 23. The worker can directly climb to the top of the tower through the second climbing main ladder 23, the auxiliary ladder 221 and the first climbing main ladder 21 to maintain the cable on the tower body 1.

The encoder can detect the rotation amount of the output shaft of the stepping motor in real time. When the PLC controller controls the stepping motor to start, the encoder detects the rotation amount of the output shaft of the stepping motor and transmits the detected data to the PLC controller in real time. The PLC controller controls the stepping motor to stop after receiving the rotation of the output shaft of the stepping motor. The rotation amount of the stepping motor is accurately controlled to ensure that the auxiliary ladder 221 can accurately rotate between the first climbing main ladder 21 and the second climbing main ladder 23, or rotate from between the first climbing main ladder 21 and the second climbing main ladder 23 to the side of the second climbing main ladder 23 to change the state of the auxiliary ladder 221.
