Detailed Description

The drawings in the embodiments of the present invention will be combined; the technical scheme in the embodiment of the utility model is clearly and completely described; obviously; the described embodiments are only some of the embodiments of the present invention; rather than all embodiments. Based on the embodiment of the utility model; all other embodiments obtained by a person skilled in the art without making any inventive step; all belong to the protection scope of the utility model.

Referring to fig. 1-3, an alarm device for a protective screening of construction engineering comprises a housing 1, wherein one end of a fixed rod 2 is fixedly connected to the inner wall of the housing 1, a spring 3 is sleeved on the outer surface of the fixed rod 2, one end of the spring 3 is fixedly connected with the inside of the housing 1, the other end of the spring is connected with the side surface of a partition plate 4, one end of a rope 5 is connected to the opposite side surface, an alarm 6 is further arranged inside the housing 1, the upper surface of the spring 3 is connected with one end of a plurality of connecting rods 7, and the other end of each connecting.

The lower end of the spring 3 is respectively connected with a first switch 9 and a second switch 10 through two vertical rods, and the first switch 9 and the second switch 10 are electrically connected with the alarm 6.

The lower end of the spring 3 is respectively connected with a third switch 11 and a fourth switch 12 through two Z-shaped rods, and the third switch 11 and the fourth switch 12 are electrically connected with the alarm 6.

The alarm 6 comprises a motor rotating shaft 13, a sleeve shaft 14 is sleeved outside the motor rotating shaft 13, a tight spring 15 is connected between the motor rotating shaft 13 and the sleeve shaft 14, one end of a plurality of rotating rods 16 is connected outside the sleeve shaft 14, the other end of each rotating rod 16 is connected with a rotating disc 17, the rotating disc is connected with one end of a plurality of rotating springs 18, and the other end of each rotating spring 18 is connected with an alarm ball 19.

The working principle is as follows:

as shown in fig. 2, the alarm device of the utility model is arranged on or in the protective column, the other end of the rope is connected with the other protective column, and when the rope is damaged by a person or is stretched or broken under the action of a heavy object or a human force, an alarm is triggered;

firstly, after the rope is stretched, at the moment, as shown in fig. 1, the spring is stretched, at the moment, the third switch and the fourth switch are in contact and are electrically communicated with the motor, the rotating shaft of the motor starts to rotate, and the clockwork spring is always in a tight state when the rotating shaft of the motor rotates;

secondly, the rope is broken, the spring is instantly shortened at the moment, on one hand, the knocking ball sequentially knocks the shell of the alarm to trigger alarm, then the first switch is contacted with the second switch to trigger the rotation of the motor rotating shaft, when the spring contracts, the partition plate impacts the clamping device to enable the alarm rope to leave the clamping device under the action of the clockwork spring, at the moment, the rotation of the motor rotating shaft is opposite to the rotation direction of the above technology, in the rotating process, the clockwork spring releases tight force to instantly drive the sleeve shaft to rotate, and further, the rotating disc is driven to rotate, each alarming ball on the rotating disc impacts the inner wall of the alarm to trigger alarm, and in the impacting process, as the total length of the rotating rod and the rotating spring is larger than the radius of the inner diameter of the alarm, the spring bends to drive the rotating disc to rotate after.

The above; is only a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; according to the technical scheme of the utility model and the improvement conception, equivalent substitution or change is carried out; are all covered by the protection scope of the utility model.
