Voice acousto-optic device for reminding people to approach danger in engineering machinery

Abstract

The invention provides a voice acousto-optic device for reminding pedestrians to approach danger for engineering machinery, and belongs to the technical field of engineering machinery, the voice acousto-optic device for reminding pedestrians to approach danger for engineering machinery comprises a protective shell and an acousto-optic alarm, the acousto-optic alarm is located in the protective shell, and the acousto-optic alarm is electrically connected with an external power supply. The top end of the protective shell is slidably connected with two protective cover plates, one side end of the protective shell is fixedly connected with an object sensor, the object sensor is electrically connected with the audible and visual alarm, a lifting mechanism is arranged between the audible and visual alarm and the protective shell, and the lifting mechanism is used for controlling the position of the audible and visual alarm; the invention discloses a voice acousto-optic device, and aims to solve the problems that most voice acousto-optic devices in the prior art are usually exposed outside, are easy to damage and are easy to be contaminated by more dust after long-time use, and the use effect of the voice acousto-optic devices is affected.
