[0002] The safety of overhead power lines is particularly important. After construction, some overhead power lines lack anti-touch devices, which causes other construction vehicles to touch the overhead lines and damage the lines. Therefore, it is necessary to set up an anti-touch device. For example, an anti-touch device for overhead power lines with a publication number of CN216412322U includes a line body, a movable clamping plate, a telescopic clamping spring, a fixed sleeve, a fixed bolt, a support connection frame and an anti-touch reminder device. The anti-touch reminder device includes a rotating motor, a motor reducer, a rotating transmission shaft, a rotating connection plate, a speaker fixing frame, a speaker reminder, a solar lamp reminder, an induction trigger and an alarm reminder. It effectively solves the current problems of lack of protection and reminder devices under overhead power lines and the inconvenience of connecting, fixing and disassembling the reminder device to the line, and realizes the purpose of the anti-touch device for overhead power lines to conveniently remind users to prevent accidental touching of the line and conveniently connect, fix and disassemble the reminder device to the line. It is a very practical anti-touch device for overhead power lines. However, the anti-touch device for overhead power lines still has the following disadvantages in actual use:

[0003] During the use of the anti-touch device, the height of the anti-touch structure is fixed, and the anti-touch device cannot be adjusted accordingly according to the installation site and status of the overhead line. Therefore, the protection effect on the overhead line is poor. In view of the above problems, it is urgently necessary to carry out innovative design based on the original anti-touch device.

[0008] Preferably, a connecting ring is fixed to the other end of the suspension rope, and the interior of the connecting ring passes through the height limiting rod. When the length of the suspension rope changes, it can drive the connecting ring to rise and fall, thereby adjusting the height of the height limiting rod.

[0009] Preferably, the connecting rope slides through the through slot, and the height of the through slot is equal to the lifting height of the fixing cylinder, and when the height of the height limiting rod is adjusted, the connecting rope can be driven to slide in the through slot.

[0010] Preferably, the fixed tube slides in close contact with the support frame, and the edge of the movable plate is slidably connected to the inner wall of the fixed tube. The fixed tube can slide on the support frame and synchronously adjust the height with the height limiting rod.

[0011] Preferably, the lifting mechanism includes a fixed block fixed to the end of the movable plate, and one of the fixed blocks and the slide rail form a sliding structure, and the slide rail is arranged on the back of the support frame.

[0012] Preferably, a movable rod is slidably penetrated inside the other fixed block, and the movable rod and the limiting hole are snap-fitted and connected, and the limiting holes are evenly spaced on the front of the support frame. The fixed cylinder can also maintain stability after lifting by snapping between the movable rod and the limiting hole.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the anti-touch device for overhead power lines can adjust the height of the anti-touch device according to the installation site and state of the overhead lines, meet the protection of different needs, and thus improve the protection effect. The specific contents are as follows:

[0014] 1. When the suspension rope is extended, the connecting ring is driven down, so that the height of the height limit rod can be lowered. When the height limit rod is lowered, the fixed tube is driven to drop synchronously to keep the same height. During the descent process, the connecting rope can be driven to slide in the through groove, which will not affect the height adjustment. After the adjusting rod reels the suspension rope, the height limit rod will be raised to meet the restrictions of different heights.

[0015] 2. When the height limit pole is touched, its position will change, either horizontally or upwardly, which can pull the connecting rope and drive the movable plate to slide in the fixed tube. Then the movable plate can press the alarm to sound an alarm, thereby alerting the construction personnel;

[0016] Furthermore, when the height of the height limit rod is adjusted, the movable rod can be pulled to slide in the fixed block and separate from the limiting hole, and then the fixed cylinder can be pushed to rise and fall. The fixed cylinder slides on the slide rail through another fixed block to ensure stability during the lifting process. After the adjustment is completed, the movable rod is pushed to engage with the corresponding limiting hole to ensure the stability of the fixed cylinder position after the lifting stops.

[0027] During use, the height of the existing anti-touch device is fixed, and the anti-touch device cannot be adjusted according to the installation site and state of the overhead line. Therefore, the protection effect of the overhead line is poor. Figure 1-Figure 2 As shown, the adjustment mechanism includes a suspension rope 6 wound around the adjustment rod 5, and one end of the suspension rope 6 is fixedly connected to the adjustment rod 5, and the adjustment rod 5 and the support plate 4 form a rotating structure through a damping member; the other end of the suspension rope 6 is fixed with a connecting ring 7, and the interior of the connecting ring 7 passes through the limited height rod 8; when the height of the anti-touch device needs to be adjusted, the adjustment rod 5 can be rotated.
