The supporting mechanism includes a lower clamp 21, two arc-shaped rails 4 and four supporting arms 23.

[0031] The lower clamp 21 is sleeved on the pole 1, and four support arms 23 are arranged around the two sides of the lower clamp 21. Two fixing sleeves 22 are fixedly installed on the two sides of the lower clamp 21 respectively. One end of the support arm 23 is inserted into the fixing sleeve 22. The support arm 23 and the fixing sleeve 22 are connected by a bolt 24. By removing the bolt 24, the support arm 23 can be disassembled.

[0032] The cross-section of the arc track 4 is C-shaped. The two arc tracks 4 are located on the lower side of the support arm 23. A docking block 42 is fixedly installed on the inner side of the end of the arc track 4. The two opposite docking blocks 42 are connected by bolts 43, so that the opposite ends of the two arc tracks 4 can be detachably connected, and the two arc tracks 4 form a closed annular track.

[0033] The arc track 4 is detachably mounted on the support arm 23 through a positioning assembly. In this embodiment, there are four groups of positioning assemblies, and the four groups of positioning assemblies are respectively arranged corresponding to the four support arms 23 .

[0034] The positioning assembly includes a connecting plate 81, a positioning pin 82 and two fixed ear plates 83. The fixed ear plate 83 is installed at the bottom of the support arm 23. The connecting plate 81 is fixedly connected to the inner side of the arc track 4, and a positioning ear plate 84 is installed on its upper surface. The positioning pin 82 crosses the positioning ear plate 84 and the two fixed ear plates 83. One end of the positioning pin 82 is fixedly connected to an iron sheet 86. A spring 87 is sleeved on the positioning pin 82. The two ends of the spring 87 are respectively fixedly connected to the iron sheet 86 and the fixed ear plate 83. Relying on the elastic force of the spring 87, the positioning pin 82 moves outward and disengages from the positioning ear plate 84.

[0035] A small electromagnet 85 is provided corresponding to the iron sheet 86, and the small electromagnet 85 is installed at the bottom of the support arm 23. By providing the small electromagnet 85, when the positioning ear plate 84 slowly rises with the arc track 4, it gradually rises to between the two fixed ear plates 83, and the small electromagnet 85 is energized to generate suction, thereby adsorbing the iron sheet 86, so that the positioning pin 82 crosses the positioning ear plate 84 and the two fixed ear plates 83, so that the arc track 4 will not fall, so as to ensure the stability of the arc track 4 during use.

[0036] N groups of monitoring units are arranged around the circular track. The monitoring units include a U-shaped seat 62 and a drive motor 61 installed on the top of the U-shaped seat 62. The U-shaped seat 62 is sleeved on the arc track 4, and a monitor 7, an alarm and a light warning lamp are fixedly installed at the bottom.

[0037] A driving wheel 63 is mounted on the output shaft of the driving motor 61, and the driving wheel 63 is arranged in the arc track 4. By controlling the operation of the driving motor 61, the driving motor 61 drives the driving wheel 63 to rotate, and then drives the U-shaped seat 62 and the monitor 7 to move along the arc track 4, and adjusts the monitoring area of ​​the monitor 7, so that the monitor 7 can monitor the construction area in real time at a high altitude, which can effectively prevent irregular and unsafe working behaviors such as personnel deviation from the trajectory, mistaken entry into dangerous areas, and tools left behind on site. When personnel mistakenly enter the construction area or dangerous area, an audible and visual alarm signal is issued to remind personnel to pay attention to safety.

[0038] A plurality of balls 64 are respectively installed on the top and bottom of the inner wall of the U-shaped seat 62. The balls 64 are arranged in the arc-shaped slide groove 41 provided in the arc-shaped track 4. By arranging the balls 64 and the arc-shaped slide groove 41, the U-shaped seat 62 is supported and restricted to ensure the stability of the U-shaped seat 62 during the sliding process and prevent the U-shaped seat 62 from leaving the arc-shaped track 4.

[0039] The control system includes a power module, a control panel, a data processing module and a warning signal issuing unit. The power module is electrically connected to the control panel. The control panel has a built-in control module. The control module is respectively connected to the small electromagnet 85, the drive motor 61, the monitor 7 and the data processing module. The monitor 7 monitors the construction area or key areas in real time. After abnormal movement of personnel is detected, the control module transmits the information to the data processing module. The data processing module analyzes, processes and stores the information and determines whether there is a risk.

[0040] The data processing module is connected to the early warning signal issuing unit, and the early warning signal issuing unit is respectively connected to the alarm and the light warning light. When there is a risk, the data processing module transmits the information to the early warning signal issuing unit, and then the early warning signal issuing unit controls the operation of the alarm and the light warning light respectively, and sends out sound and light alarm signals to remind personnel to pay attention to safety.

[0041] When used specifically, the present invention is a warning device for preventing misentry for a substation. First, the lower clamp 21 is installed at a suitable height of the pole 1, and then the support arm 23 is inserted into the fixing sleeve 22 and connected and fixed by bolts 24, and then the remaining support arms 23 are installed one by one; After the four support arms 23 are installed, the two arc tracks 4 are assembled on the ground, and then the arc track 4 is slowly lifted by a crane. When the positioning ear plate 84 slowly rises with the arc track 4, it gradually rises to between the two fixed ear plates 83. The small electromagnet 85 is energized by the control panel to generate suction to adsorb the iron sheet 86, so that the positioning pin 82 crosses the positioning ear plate 84 and the two fixed ear plates 83, so that the arc track 4 will not fall, and then the various electrical equipment are powered on and debugged, and the device is installed on the pole 1 near the construction area or key area; The operation control panel controls the operation of the drive motor 61, so that the drive motor 61 drives the rotation of the drive wheel 63, and then drives the U-shaped seat 62 and the monitor 7 to move along the arc track 4, and adjusts the monitoring area of ​​the monitor 7, so that the monitor 7 can monitor the construction area in real time at high altitude. After abnormal movement of personnel is found, it is transmitted to the data processing module through the control module. The data processing module analyzes, processes and stores it, and determines whether there is a risk. When there is a risk, the data processing module transmits the information to the early warning signal issuing unit, and then the early warning signal issuing unit controls the operation of the alarm and the light warning light respectively, and sends out sound and light alarm signals to remind personnel to pay attention to safety.
