The laser radar 2 fixedly installed on the upper front side of the device body 1 performs real-time scanning of a 180° horizontal rectangular area of ​​30m*30m. When an obstacle or object intrusion is detected, an alarm signal is output. After the alarm is triggered, the strobe light 3 starts to flash, and the speaker 4 starts to alarm. The speaker 4 can be set with broadcast content and alarm sound, ensuring a good intrusion prevention and early warning effect of the construction area intrusion prevention and security monitoring device. An antenna 8 set on the right side of the device body 1 is used to enhance the alarm signal and link with a wireless alarm.

[0033] A level 9 is fixedly mounted on the upper front side of the equipment body 1, and an antenna 8 is fixedly mounted on the upper right side of the equipment body 1. A hook 7 is fixedly connected to the rear end of the equipment body 1, and a first clamping plate 5 is fixedly installed on the lower front side of the equipment body 1. A fixing rod 6 is movably connected to the outer side of the first clamping plate 5, and a second clamping plate 13 is movably connected to the outer side of the rear end of the fixing rod 6. The hook 7 fixedly installed at the rear end of the equipment body 1 facilitates the installation of the equipment body 1 on the highway guardrail. Furthermore, by placing the equipment body 1 on the bridge protrusion, the equipment... The machine body 1 drives the first clamping plate 5 to be installed on the outside of the bridge protrusion, and then the second clamping plate 13 is placed on the rear side of the first clamping plate 5. The fixing rod 6 is rotated to connect the fixing rod 6 to the outside of the first clamping plate 5, thereby connecting the fixing rod 6 to the outside of the second clamping plate 13. This allows the first clamping plate 5 and the second clamping plate 13 to be clamped on the outside of the bridge protrusion, making it convenient to install the machine body 1 on the bridge. The level 9 fixedly installed on the front side of the upper end of the machine body 1 facilitates leveling during the installation of the machine body 1.

The fixing rod 6 is connected to the second clamping plate 13 by a thread, and the fixing rod 6 is symmetrically distributed about the center line of the second clamping plate 13. Rotating the fixing rod 6 causes it to be threaded on the outside of the first clamping plate 5, and thus threaded on the outside of the second clamping plate 13. This allows the first clamping plate 5 and the second clamping plate 13 to be clamped on the outside of the bridge protrusion, facilitating the installation of the equipment body 1 on the bridge. The level 9, which is fixedly installed on the front side of the upper end of the equipment body 1, facilitates leveling during the installation of the equipment body 1.
