[0029] This utility model proposes a laser rangefinder alarm, which aims to automatically detect obstacles using a laser rangefinder and simultaneously trigger an alarm light to emit an audible and visual alarm, reminding construction workers to take immediate personal safety precautions, reduce personal injury, and avoid dangerous situations. It not only has high detection sensitivity but also issues alarms promptly, stably, and reliably.

[0030] Please see Figures 1 to 3 In one embodiment of this utility model, the laser rangefinder alarm 10 includes:

[0031] Warning cylinder 1;

[0032] A laser rangefinder 2, which is rotatably mounted on the warning cylinder 1;

[0033] Alarm light 3, the alarm light 3 is located on the side of the laser rangefinder 2 away from the warning cylinder 1;

[0034] The main control board is electrically connected to the laser rangefinder 2 and the alarm light 3.

[0035] The technical solution of this utility model involves installing a laser rangefinder 2 on the warning cylinder 1, and providing an alarm light 3 on the side of the laser rangefinder 2 away from the warning cylinder 1. Thus, when a vehicle enters the surrounding area of ​​the work environment, the target vehicle can be automatically detected by the laser rangefinder 2 from a distance, simultaneously triggering the alarm light 3. The alarm light 3 then emits an audible and visual alarm, reminding construction workers to take immediate safety precautions to reduce personal injury and avoid dangerous situations. It should be noted that the laser rangefinder 2 is rotatably connected to the warning cylinder 1, allowing for arbitrary adjustment of its angle to adapt to complex environments, enabling more accurate detection of obstacles, timely alarm issuance, and reduced personal injury to prevent dangerous situations.

[0036] It should be noted that the warning cylinder 1 is cone-shaped with a cross-section that gradually decreases in size from bottom to top, thereby lowering its center of gravity and improving stability. Specifically, when the warning cylinder 1 is placed on the ground, the end with the larger cross-section is placed on the ground, while the end with the smaller cross-section is used to support the laser rangefinder 2 and the alarm light 3. This makes the light emitted by the alarm light 3 more visible to pedestrians and drivers, thereby improving the warning effect. It is known that the warning cylinder 1 can be made of materials such as plastic or rubber to achieve the purpose of being lightweight and easy to carry, and no limitation is made here.

[0037] In one implementation, please refer to Figures 1 to 3The laser rangefinder 2 includes a housing 21, a laser ranging radar 22, and a transparent component 23. The housing 21 is rotatably mounted on the warning cylinder 1. The housing 21 forms a receiving cavity with a mounting opening 2121. The laser ranging radar 22 is installed in the receiving cavity and directly faces the mounting opening 2121. The transparent component 23 covers the mounting opening 2121. By installing the laser rangefinder 2 in the receiving cavity, it is prevented from being contaminated by the outside environment, thereby ensuring the normal detection of the laser rangefinder 2. At the same time, a mounting opening 212 is provided on one side of the housing 21. 1. The laser beam emitted by the laser rangefinder 2 acts on the obstacle through the mounting port 2121. At the same time, in order to prevent external contaminants from contaminating the laser rangefinder 2, a transparent part 23 is provided on the mounting port 2121. This not only seals the mounting port 2121, but also allows the laser beam emitted by the laser rangefinder 2 to pass smoothly through the housing 21 and act on the obstacle. In this way, not only can the laser beam of the laser rangefinder 2 pass smoothly through the housing 21 and be emitted to the outside, but the laser rangefinder 2 is also effectively protected from external contamination, thereby ensuring the normal detection of the laser rangefinder 2.

[0038] It should be further explained that the housing 21 includes a first outer shell 211 and a second outer shell 212. The first outer shell 211 forms a receiving cavity with an opening, and the second outer shell 212 covers the opening. The second outer shell 212 can be installed on the first outer shell 211 by screws or the like, and the mounting port 2121 is provided on the second outer shell 212. In this way, it is convenient to disassemble and assemble the second outer shell 212 to install and maintain the laser rangefinder 2 installed in the housing 21.

[0039] In one implementation, please refer to Figure 1 and Figure 3 The transparent component 23 is made of high-transparency glass, which allows the laser beam of the laser rangefinder 2 to pass smoothly through the housing 21 and be emitted to the outside, effectively protecting the laser rangefinder 2 from external contamination and ensuring its normal detection function. It should be noted that the transparent component 23 can be installed on the mounting opening 2121 by means of adhesive bonding or other methods.
