When the detection contact detects that the construction worker is electrocuted, the third drive motor 33 can be controlled to rotate to wind and store the connecting wire 28, so that the connecting wire 28 can pull the construction worker to move away from the electric shock point. At the same time, the alarm 22 sounds an alarm to ensure the safety of power construction.

[0032] The present invention can be explained by the following operation mode:

[0033] In the present invention, when the electric power construction site safety supervision and management alarm device is in use, the locking universal wheel 2 can move the device to the supervision point, the third drive motor 33 drives the second winding rod 27 to rotate to unwind the connecting wire 28, and the binding belt 30 is tied to the construction personnel through the combination of the fleece surface Velcro and the hook surface Velcro. The connecting wire 28 is in a loose state, which enables the construction personnel to perform construction at different positions. The U-shaped block 26 is pulled upward to unwind the connecting wire 25, so that the connecting wire 25 can be connected to the circuit at the construction site;

[0034] The camera 21 can monitor the safety of personnel in the construction site. The servo motor 18 is started to drive the double-headed screw 17 to rotate, and the two adjustment sliders 16 can be moved closer to or away from each other under the action of the thread engagement, and then the movable plate 19 can be moved up and down under the connection of the two connecting rods 20, so as to adjust the height of the camera 21 to meet different usage requirements;

[0035] The second driving motor is started to drive the suction fan blades 6 to rotate, so that the dust in the working space can be sucked into the dust reduction box 5 through the dust suction pipe 11. The cleaning brush 8 can rotate synchronously with the suction fan blades 6 to clean the filter screen to prevent dust from adhering to the filter screen and clogging it. The cleaned dust can fall into the dust storage box 10 through the drop opening formed between the partition plate 9 and the bracket 7 for collection;

[0036] If the camera 21 detects that the construction worker is abnormal, the alarm 22 can sound an alarm, and other construction workers can be reminded to go and check. If the detection contact detects that the construction worker is electrocuted, the third drive motor 33 can be controlled to rotate to wind and store the connecting wire 28, so that the connecting wire 28 can pull the construction worker to move away from the electric shock point. At the same time, the alarm 22 sounds an alarm, which is conducive to other construction workers to disconnect the circuit in time; if the connecting wire 25 and the short-circuit detector 23 detect a short circuit in the circuit, the alarm 22 can sound an alarm, so that other construction workers can disconnect the circuit in time, and then the camera 21, the contact detector and the short-circuit detector 23 cooperate to ensure the safety of power construction, and the alarm 22 can be set to issue different alarms, which is conducive to distinguishing the alarms issued by the camera 21, the contact detector and the short-circuit detector 23;

[0037] The baffle 31 is rotated so that it no longer blocks the dust storage box 10, and the dust storage box 10 can be pulled out for cleaning.
