Various materials and machinery will be used in the excavation process of the deep foundation pit and the construction site is relatively messy. Since the alarm equipment is exposed to the outside for a long time, it is easy to be damaged by collision with gravel, soil or building materials, which makes the alarm equipment unable to continue to be used and has a certain impact on the safety of surrounding personnel.

[0030] Reference Figure 2 and Figure 3As shown, in this embodiment: the adjustment structure 5 includes several fixed plates 501, and the several fixed plates 501 are fixedly connected to the alarm box body 1. The upper surface of the fixed plate 501 is fixedly connected with a connecting rod 502, and the arc surface of the connecting rod 502 is slidably connected with a positioning block 503. The arc surface of the connecting rod 502 is sleeved with a spring 504, and the two ends of the spring 504 are respectively fixedly connected to the fixed plate 501 and the positioning block 503. A sliding groove 505 is provided on the upper surface of the fixed plate 501, and a slider 506 is slidably connected to the inner wall of the sliding groove 505. The upper surface of the slider 506 is fixedly connected to a limiting block 507. A protective cover 508 is placed on the upper surface of the alarm box body 1, and fixed grooves 509 are provided all around the protective cover 508. The limiting block 507 and the fixed groove 509 are slidably connected. By setting the adjustment structure 5, the alarm light 4 can be protected to avoid gravel, soil and construction during construction. The material causes damage to the alarm light 4, so that it can maintain the function of the alarm device to the maximum extent and improve the safety during the construction process. One side of several positioning blocks 503 is fixedly connected to the limit frame 510, and the limit frame 510 is in contact with the alarm box body 1. The limit frame 510 can drive the positioning block 503 to move, thereby achieving the effect of convenient control of the positioning block 503. One side of the positioning block 503 is rotatably connected to a pulley 511, and the arc surface of the pulley 511 is slidably connected to the limit block 507. The pulley 511 can reduce the friction between the positioning block 503 and the limit block 507, so that the positioning block 503 can better push the limit block 507 to move. The inner wall of the slide groove 505 is fixedly connected to the limit rod 512, and the limit rod 512 and the slider 506 are slidably connected. The limit rod 512 can limit the slider 506, thereby avoiding the position offset of the slider 506 when it moves.

[0031] Reference Figure 4 and Figure 5As shown, in this embodiment: the adjustment structure 5 includes a positioning frame 601, the positioning frame 601 and the alarm box body 1 are fixedly connected, the inner wall of the positioning frame 601 is slidably connected to a connecting block 602, the lower surface of the connecting block 602 is fixedly connected to a first connecting frame 603, the lower surface of the first connecting frame 603 is fixedly connected to two fixed blocks 604, the two fixed blocks 604 are fixedly connected to a connecting rod 605 on one side close to each other, the arc surface of the connecting rod 605 is rotatably connected to a screw 606, the arc surface of the screw 606 is threadedly connected to a round block 607, the inner wall of the positioning frame 601 is slidably connected to an auxiliary block 608, the lower surface of the auxiliary block 608 is fixedly connected to a second connecting frame 609, the second connecting frame 609 The lower surface of the block 607 is fixedly connected with a groove, and the auxiliary structure 6 can be used to conveniently fix the plug to prevent the plug from detaching and causing the alarm device to fail to alarm in time, thereby ensuring that the alarm device is always in working condition at critical moments. The arc surface of the round block 607 is provided with anti-slip grooves 611, and the anti-slip grooves 611 are evenly distributed on the round block 607. The anti-slip grooves 611 can increase the friction of the round block 607 to prevent people from slipping when turning the round block 607. A soft pad 612 is fixedly connected to one side of the round block 607. The cross-section of the soft pad 612 is circular. The soft pad 612 can prevent the round block 607 from directly contacting the concave block 610, thereby preventing the concave block 610 from wearing.

[0032] Working principle: by setting the adjustment structure 5, first use the limit frame 510 to move the positioning block 503 on the connecting rod 502, so that the positioning block 503 drives the spring 504 to contract, and then move the protective cover 508 to cover the alarm light 4. At this time, release the limit frame 510. When the limit frame 510 is released, the spring 504 will drive the positioning block 503 to move upward, so that the positioning block 503 pushes the limiting block 507 to move. When the limiting block 507 moves, it also drives the slider 506 to move in the slide groove 505 of the fixed plate 501 until the limit block 507 is inserted into the fixed groove of the protective cover 508. 509, the protective cover 508 is fixed at this time, and then the start button of the alarm box body 1 is pressed again. When someone passes through the deep foundation pit, the alarm light 4 will flash and the speaker 2 will sound an alarm. Among them, the limit frame 510 can drive the positioning block 503 to move, thereby achieving the effect of convenient control of the positioning block 503. The pulley 511 can reduce the friction between the positioning block 503 and the limit block 507, so that the positioning block 503 can better push the limit block 507 to move. The limit rod 512 can limit the slider 506, thereby avoiding the position offset of the slider 506 when moving.

[0033] By setting the auxiliary structure 6, when the plug is connected to the socket 3, the first connecting frame 603 is moved first to drive the connecting block 602 to move in the positioning frame 601, and then the second connecting frame 609 is moved to drive the auxiliary block 608 to move in the positioning frame 601, so that the second connecting frame 609 and the first connecting frame 603 are fitted together, and the plug frame column is inserted. At this time, the screw 606 is rotated to make the screw 606 rotate on the connecting rod 605 of the fixing block 604, and the screw 606 is placed inside the concave block 610. Then, the round block 607 on the screw 606 is rotated with the help of the anti-slip groove 611 to fix it to the concave block 610. At this time, the first connecting frame 603 and the second connecting frame 609 are fixed. Among them, the anti-slip groove 611 can increase the friction of the round block 607 to prevent the person's hand from slipping when rotating the round block 607. The soft pad 612 can prevent the round block 607 from directly contacting the concave block 610, thereby preventing the concave block 610 from being worn.
