During the day, the colored warning sign 11 is located in the front, and at night, the warning sign 4 is flipped by the driving component, so that the LED warning sign 30 of the warning sign 4 is flipped to the front, and at the same time, the rotating cylinder 34 is flipped from the bottom end of the warning sign 4 to At the top, when the rotating cylinder 34 is located at the bottom of the warning sign 4, the rotating cylinder 34 inside it blocks the installation port 40 under the action of the counterweight plate 38, effectively preventing the mosquito repellent liquid therein from evaporating during the day. When the rotating cylinder 34 flips from the bottom of the warning sign 4 to the top, the rotating cylinder 34 is rotated by the action of the counterweight plate 38, and moves to the end along the positioning groove 36 through the positioning bar 37 and is locked. At this time, the opening groove 39 coincides with the installation port 40, and the mosquito repellent liquid therein flows from the opening groove 39 and the installation port 40 to the cotton strip 32 under the action of gravity, and is volatilized through the cotton strip 32, thereby achieving the effect of repelling mosquitoes at night. A heating plate 35 is provided at the bottom of the warning sign 4, and the heating plate 35 is in contact with the cotton strip 32, and the volatilization effect of the mosquito repellent absorbed by the cotton strip 32 is improved by the heating plate 35.

[0046] In the present invention, the cleaning component 1 includes a rotating frame 24, which is rotatably connected to the end of the rotating frame 10. The end of the rotating frame 10 is sleeved with a torsion spring 23, and the two ends of the torsion spring 23 are respectively fixed to the rotating frame 10 and the rotating frame 24. The top of the rotating frame 24 is fixed with a telescopic square tube 21 by bolts, and the top of the telescopic square tube 21 is fixed with a scraper 20 by bolts, and the scraper 20 can contact the sound hole 13 opened by the speaker 12.

The second scraper 20 is fixed to the rotating frame 24 and the scraper 20. When the rotating frame 10 flips clockwise, the rotating frame 24 is driven to rotate by the torsion spring 23. The rotating frame 24 rotates, driving the scraper 20 on the telescopic square tube 21 to move along the outer surface of the speaker 12. Under the joint action of the tension spring 22 and the telescopic square tube 21, the scraper 20 can always be in contact with the outer surface of the speaker 12 and clean the sound-transmitting hole 13 opened therein.

After the rotating rod 25 rotates in the opposite direction to reset, the scraping strip 17 is driven to move outward and reset through the reset elastic rope 18.

[0048] The present invention is divided into the following steps when used:

[0049] S1: First, the sensing device 7 detects whether there is a human body approaching within a preset distance range. The control unit 43 receives the signal from the sensing device 7 and determines whether the human body is approaching within the preset safety distance based on the signal. Then, the warning output unit 9 sends a warning signal when the control unit 43 determines that a human body is approaching within the safety distance. The all-round visual coverage formed by the camera 14 further improves the monitoring effect.

[0050] S2: The colored warning signs 11 for daytime and the LED warning signs 30 for nighttime are respectively provided on both sides of the warning sign 4, so as to give full play to the visual warning effect while saving energy. In addition, a video of an electric shock accident is played on two display screens 16 provided on the installation sign 5 in a loop, thereby providing a danger warning.

[0051] S3: A communication module is provided for transmitting the warning signal to a remote monitoring center or a mobile device of a manager. At the same time, the control unit 43 is provided with a timing function for automatically shutting down the warning output unit 9 when no one approaches continuously to save power. The control unit 43 can also be connected to the power equipment and set a timer so that if the human body does not leave for a certain period of time, the control unit 43 automatically disconnects the power supply of the power equipment to prevent possible safety risks.

[0052] S4: When switching between the color warning sign 11 for daytime and the LED warning sign 30 for nighttime, the rotation of the rotating frame 10 and the rotating rod 25 is achieved by starting the dual-axis synchronous motor 31;

[0053] S5: As the rotating frame 10 flips clockwise, the rotating frame 24 is driven to rotate along with it by the torsion spring 23. The rotating frame 24 rotates, driving the second scraper 20 on the telescopic square tube 21 to move along the outer surface of the speaker 12. Under the combined action of the tension spring 22 and the telescopic square tube 21, the second scraper 20 can always be in contact with the outer surface of the speaker 12 and clean the sound transmission hole 13. The torsion spring 23 ensures that the second scraper 20 is out of position when it moves to the bottom end of the speaker 12.

[0054] S6: The rotating rod 25 rotates to rotate the lever 26. When the lever 26 rotates, the elastic pull rope 19 pulls the two scraping strips 17 to move inward along the polishing rod 27 and clean the display screen 16.

[0055] S7: At the same time, during the day, the colored warning sign 11 is located in the front, and at night, the warning sign 4 is driven to flip through the driving component, so that the LED warning sign 30 of the warning sign 4 flips to the front, and at the same time, the rotating cylinder 34 flips from the bottom end of the warning sign 4 to the top end. When the rotating cylinder 34 is located at the bottom end of the warning sign 4, the rotating cylinder 34 inside it blocks the mounting port 40 under the action of the counterweight plate 38, effectively preventing the mosquito repellent liquid therein from evaporating during the day. When the rotating cylinder 34 flips from the bottom end of the warning sign 4 to the top end, the rotating cylinder 34 is rotated by the action of the counterweight plate 38, and moves to the end along the positioning groove 36 through the positioning bar 37 and is locked. At this time, the opening groove 39 coincides with the mounting port 40, and the mosquito repellent liquid therein flows from the opening groove 39 and the mounting port 40 to the cotton strip 32 under the action of gravity, and evaporates through the cotton strip 32, thereby achieving the effect of repelling mosquitoes at night and effectively improving the service life of the warning device.
