[0002] The intelligent safety alarm for an aerial work vehicle, especially for the safety alarm, is an indispensable safety device in modern construction and operations, and can be used on cranes, hoists, and fire trucks;

[0003] When performing high-altitude operations on a building, a certain amount of construction waste will be generated. The falling of the construction waste will fall into the interior of the hanging basket, which may cause the hanging basket to shake. However, the existing safety alarms cannot timely detect whether there is a risk of falling objects nearby;

[0004] In order to overcome the above defects, reference can be made to a kind of alarm device that can sense high-altitude falling objects disclosed in the prior art (Chinese patent with the application number CN202420006633.2 and the publication date of August 16, 2024). When an object falls and impacts the force-receiving plate, the alarm will sound, which can timely detect whether there is a risk of falling objects nearby and timely remind the workers, so that the workers can stay away from the building during this period to ensure safety;

[0005] Although the prior art can overcome the above defects, there are still certain deficiencies in the working process. The safety alarm lacks a protection mechanism for it. When the aerial work vehicle is lifted, the safety alarm may be damaged.

[0031] The setting of the operation vehicle body 2 can drive the aerial work basket 1 to adjust its position. When the position of the aerial work basket 1 is adjusted to a certain position, in order to facilitate safety monitoring at this time, by starting the fixed motor 3, the output end of the fixed motor 3 drives the threaded rod 4 to rotate, so that the output end of the threaded rod 4 drives the connecting sleeve 5 connected by threads to move, and the connecting sleeve 5 drives the mounting plate 6 to move. The slider 7 fixed to the back of the mounting plate 6 slides inside the chute 8, so as to realize the adjustment of the position of the mounting plate 6. The mounting plate 6 will drive the alarm monitor 18 and the alarm speaker 19 to move, so as to monitor and process at different positions during aerial work. If a threat occurs, the alarm monitor 18 monitors and the alarm speaker 19 gives an alarm, which can facilitate the reminder of the safety of the operators at this time.

[0032] Embodiment 2: In order to protect the alarm monitor 18 and the alarm speaker 19, and to solve the problem that the safety alarm on the current market lacks a mechanism for protecting it, when the aerial work vehicle is lifted, it may cause damage to the safety alarm. Reference can be made to the attached Figure 1 - Attachment Figure 6 , a protection mechanism is provided inside the mounting plate 6. The protection mechanism is arranged on the left and right sides of the mounting plate 6, and the protection mechanism acts on the outside of the mounting plate 6 to protect the alarm monitor 18 and the alarm speaker 19 fixed on the surface of the mounting plate 6. The protection mechanism includes sliding plates 14 arranged on the left and right sides of the mounting plate 6. A connecting gear 10 is rotatably arranged at the back of the mounting plate 6. The front shaft end of the connecting gear 10 is rotatably arranged inside the mounting plate 6 and is fixed with a rotating gear 11. Connecting racks 12 are meshed and connected to the upper and lower ends of the rotating gear 11 respectively. One ends of the upper and lower groups of connecting racks 12 are respectively fixed to one side of the sliding plate 14.
