Description

Technical Field

[0001] This utility model relates to the field of safety alarm device technology, and in particular to an acoustic, optical and electrical safety alarm device for construction sites. Background Technology

[0002] Most work sites are located in hazardous areas, some even on driveways. To prevent accidents, temporary traffic control and warning devices are usually set up around the work site. However, existing temporary traffic control and warning devices can only provide silent visual warnings, which are effective in alerting workers but cannot promptly alert them when danger occurs, leading to safety accidents.

[0003] Therefore, how to design a simple, inexpensive, and effective sound, light, and electrical safety alarm device for construction sites is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] This utility model provides an acoustic, optical, and electronic safety alarm device for construction sites, which solves the technical problem that existing temporary warning devices have limited warning effects and cannot remind workers.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a sound, light, and electricity safety alarm device for construction sites, comprising: a housing, a microphone, multiple radars, and a controller.

[0006] The lower front of the housing is provided with multiple sound holes and the upper front is fixed with multiple first flashing lights at intervals; the microphone is fixed inside the housing and its sound output end is arranged opposite to the multiple sound holes; multiple radars are fixed at intervals on the upper part of the housing to detect the approach distance of vehicles in the surrounding area of ​​the housing; the controller is electrically connected to the multiple first flashing lights, the microphone and the multiple radars respectively.

[0007] The beneficial effects of this utility model are: it improves the structure of traditional temporary warning devices, firstly using radar to detect vehicles approaching in the surrounding area of ​​the construction site, and then using a microphone and multiple first flashing lights to provide sound and light reminders. When a vehicle approaches at close range, sound and light can remind the vehicle and on-site workers, avoid accidents, and improve on-site work safety.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, multiple of the first flashing lights are arranged in a "slow" shape.

[0010] The further beneficial effect of adopting the above is that arranging multiple first flashing lights in a "slow" shape can effectively remind vehicles approaching the work site (vehicles within 10 meters of the work site) to reduce their speed and avoid accidents.

[0011] Furthermore, it also includes a plurality of second flashing lights, which are located between a plurality of first flashing lights and a plurality of sound outlets and are fixed at intervals on the front side of the housing; the controller is electrically connected to the plurality of second flashing lights respectively.

[0012] The further beneficial effect of adopting the above is that by using multiple second flashing lights in conjunction with multiple first flashing lights, it is possible to effectively remind vehicles approaching the work site (vehicles 3 to 5 meters away from the work site) to reduce their speed and avoid accidents.

[0013] Furthermore, it also includes a constantly flashing orange alarm light, which is fixed to the outside of the housing via a conduit; the controller is electrically connected to the constantly flashing orange alarm light.

[0014] The additional beneficial effect of adopting the above is that adding a constantly flashing orange-red alarm light can enhance the light warning effect.

[0015] Furthermore, it also includes a loudspeaker, which is located outside the housing; the controller is electrically connected to the loudspeaker.

[0016] The further beneficial effect of adopting the above is that by using a loudspeaker electrically connected to the controller, it can automatically warn vehicles approaching the work site (vehicles within 10 meters of the work site) to reduce their speed and avoid accidents.

[0017] Furthermore, it also includes multiple pads, which are fixed at intervals to the bottom end of the housing.

[0018] Furthermore, multiple radars are respectively arranged on the front and opposite sides of the housing.

[0019] The further beneficial effect of adopting the above is that by distributing multiple radars on the front and opposite sides of the housing, the surrounding area of ​​the work site can be detected more effectively. Attached Figure Description
