After the power line 3 is penetrated into the sliding frame 12, the fixing frame 1 is made to descend through the weight of the alarm device, the limiting ball part 121 can be separated from the embedded circular groove 181 through the gravity, meanwhile, the elastic force of the spring is released, the sliding frame 12 is made to slide upwards quickly, the sliding frame 12 and the opening 101 of the fixing frame 1 are closed in a staggered opening and closing mode during sliding, and the power line 3 is prevented from falling from the sliding frame 12.

in use, the alarm device is raised slightly above the power line 3 by the long pole support hook 11, with the opening 101 aligned with the power line 3 and the power line 3 passing through the passageway, as in the condition of fig. 1. Then the long rod loosens the hook 11, the alarm device makes the top of the sliding frame 12 contact with the power line 3 due to the action of gravity, and at the moment, the fixed frame 1 moves downwards due to the action of gravity to make the two openings 101 dislocate to frame the power line 3, so that the power line is prevented from falling out. And because the mount 1 moves down (namely the carriage 12 moves up relative to the mount 1), the top surface of the carriage 12 can be pressed against the extrusion plate 15, the holding plate 16 rotates towards the center to clamp the power line 3, the limiting ball 121 can be separated from the embedded circular groove 181 when the mount 1 moves down, the spring elastic force recovers to accelerate the moving up speed of the carriage 12 and apply pressure to the extrusion plate 15, the holding plate 16 is assisted to drive to rotate to clamp the power line 3, and the alarm device is hung on the power line 3 and is not easy to slide on the power line 3.

After the microwave mobile detection sensor V1 is hung, whether a moving object exists in a set range is detected in real time, when the microwave mobile detection sensor V1 detects that the moving object exists in the set range, a high level signal is output, the first triode Q1 is enabled to pass through, so that the P3.3 end of the MCU chip U1 is interrupted, the MCU chip U1 receives feedback, the P1.1 end outputs a low level to enable the positive electrode of the high decibel loudspeaker T1 to sound, meanwhile, the P1.2 end, the P1.4 end and the P1.8 end output low levels, the first alarm lamp LED1, the second alarm lamp LED2 and the third alarm lamp LED3 flicker, and alarm is given out in a sound and light alarm mode.

When needing to take off, only need catch on couple 11 with the stock and mention upwards, break through alarm device's weight, carriage 12 receives the action of gravity to make stripper plate 15 external force disappear, embraces splint 16 and rotates gradually this moment and relieve power line 3 to initial position. And the sliding frame 12 moves downwards relative to the fixed plate under the action of gravity, the limiting ball piece 121 can be inserted into the embedded circular groove 181 during the downward movement of the sliding frame 12, so that the sliding frame 12 and the fixed frame 1 are reset, and finally the two openings 101 are aligned to open the passage, so that the alarm device can be conveniently taken down.

In summary, the power line false-collision prevention alarm device provided by the invention enables the clamping mechanism to act through the sliding driving mechanism, so that the alarm device is suspended on the power line, and outputs an alarm signal when the induction alarm module detects that a moving object (such as a crane, an engineering vehicle and a large truck) is in a preset range, so as to prompt that the moving object cannot approach the power line.

The invention can clamp the power line by only hanging the alarm device on the power line by using the long rod, can detect whether a crane or an engineering vehicle leans against the uniform power line after hanging, and can alarm timely and reliably by sound and light alarm in abnormal conditions.
