The fixed hoop is fixed to the movable end of the second rotating arm, one end of the movable hoop is hinged to one end of the fixed hoop, and the other end of the movable hoop is locked with the fixed hoop by a first butterfly bolt.

[0008] In the above embodiment, a limiting device is also installed on the climbing rope, and the limiting device is used to limit the climbing height of the hoisting machine on the climbing rope.

[0009] In the above embodiment, the hook includes a hook body, a connecting rod, a pull rope and a locking plate, the connecting rod is provided with an axially arranged slideway, a slider is slidably installed in the slideway, a through hole connected to the slideway is provided at the top of the connecting rod, a linkage rod matching the size of the through hole is fixed at the bottom of the hanging ring, the linkage rod is slidably installed in the through hole and fixed to the slider, the connecting rod is vertically arranged, a hook body is fixed on one side of the connecting rod, the hook body and the connecting rod are enclosed to form a hanging hole with an opening facing downwards and matching the size of the hanging point.

[0011] In the above embodiment, the Y-shaped limit rod includes a vertically arranged straight rod and an obliquely arranged guide rod, the bottom of the guide rod is fixed on the straight rod, and an angle is provided between the guide rod and the straight rod to form a Y-shaped structure with an opening facing upward, and the bottom of the straight rod is vertically inserted on the telescopic end of the telescopic arm.

[0012] The present invention also includes a method for high-altitude operation without power outage in a distribution network using the above-mentioned high-altitude operation monitoring device without power outage in a distribution network, including the following specific steps:

[0013] S1. Connect the drone's hanging system to the lifting ring, use the drone to lift the lifting ring to the height of the hanging point, and then hang the hook under the lifting ring on the distribution network line. The climbing rope under the hook hangs down naturally, and the length of the climbing rope matches the distance from the hanging point to the ground.

[0014] S2. Install the monitoring equipment on the pan / tilt of the high-altitude hovering device and fix the Y-shaped limit rod on the balance rod;

[0015] S3, connecting the electric lifting device to the climbing rope, and fixing the balancing rod on the two-axis rotating arm of the electric lifting device;

[0016] S4. Control the electric lifting device to move upward along the climbing rope through the remote control, and at the same time control the two-axis rotating arm through the remote control to ensure that the balance bar is in a vertical state. When the electric lifting device reaches the position of the upper limit device on the climbing rope, the electric lifting device automatically stops, so that the mounting point is placed in the Y-shaped limit rod to limit the balance bar. At this time, the deployment of the monitoring equipment is completed, and the global monitoring of the maintenance operation begins;

[0017] S5. After the operation is completed, the electric lifting device is controlled to descend and the high-altitude hovering device and monitoring equipment are removed;

[0018] S6. Use the drone to remove the hook from the mounting point to complete the operation.

[0019] In the above embodiment, in step S1, the specific hanging steps of the hook are as follows: the drone lifts the lifting ring upward, the lifting ring drives the linkage rod to drive the slider to move upward in the slideway, the slider drives the pull rope to move, and the pull rope drives the free end of the locking plate to rotate upward around the hinge axis to open the opening of the hanging area; when the drone hangs the hook on the hanging point, the drone is separated from the lifting ring. At this time, the lifting ring, the linkage rod and the slider move downward under the action of gravity. At this time, the locking plate is not restricted by the pull rope. The free end of the locking plate rotates downward around the hinge axis under the action of gravity and falls back into the slot of the hook body. At this time, the locking plate closes the opening of the hanging area.

[0020] With the above structure, the present invention has the following advantages:

[0021] 1. This device consists of a high-altitude hovering device, monitoring equipment, and a climbing system. The design of the climbing system and the electric lifting device can quickly and safely lift and fix the high-altitude hovering device and the monitoring equipment to the high-altitude working position, solving the problem of setting up the monitoring device.

[0022] 2. The device is equipped with a self-locking hook, which cooperates with the drone to operate. When the drone lifts the lifting ring, the hook opening opens. After the drone is separated from the lifting ring, the hook opening is closed, so that when the hook is hung on the hanging point, it is prevented from being detached from the hanging point, ensuring safety during operation and reducing the risk of accidents.

[0023] 3. The electric lifting device of the present application is provided with a two-axis rotating arm, which is connected to the balance bar through the two-axis rotating arm to adjust the angle of the balance bar, thereby ensuring the verticality of the balance bar. At the same time, in conjunction with the pan-tilt head, the monitoring equipment can adjust the monitoring angle according to actual conditions to adapt to different operating requirements.

[0024] 4. The present invention also includes a method for high-altitude operations without power outages in the distribution network, which utilizes drone technology in conjunction with the climbing system of the present application to achieve unmanned and safe fixing of monitoring equipment to a set mounting point, so that the monitoring equipment is located at a commanding height of the line, thereby achieving monitoring of high-altitude operations.

[0025] In summary, the present invention can safely and conveniently deploy monitoring equipment to the set mounting point, so that the monitoring equipment is located at the commanding height of the line, and the monitoring of high-altitude operations can be realized, which can help operators develop good safety habits and reduce or even eliminate violations. The present invention combines modern technologies such as monitoring equipment monitoring and remote control to comprehensively improve the safety of maintenance operations and the operating ability of personnel, thereby ensuring the effective implementation of the "four no harm" principle in actual operations.

[0036] like Figure 5As shown, the hook 12 is a self-locking hook, and the hook 12 includes a hook body 121, a connecting rod 122, a pull rope 124 and a locking plate 125. The connecting rod 122 is provided with a slideway arranged along the axial direction, and a slider is slidably installed in the slideway. The top of the connecting rod 122 is provided with a through hole connected to the slideway, and the bottom of the ring 11 is fixed with a linkage rod matching the size of the through hole, which is slidably installed in the through hole and fixed to the slider. The connecting rod 122 is arranged vertically. A hook body 121 is fixed to one side of the connecting rod 122, and the hook body 121 and the connecting rod 122 enclose a mounting area with an opening facing downward and matching the size of the mounting point. The connecting rod 122 is provided with a long strip groove connected to the slideway on the side facing the hook body 121, and the long strip groove matches the size of the locking plate 125.

Specifically, the balance pole 21 is fixed to the hoist 144 by a first clamp 143.

[0038] like Figure 3As shown, a guide device 23 is also installed on the balance pole 21.
