Description

Technical Field

[0001] This utility model relates to the technical field of safety warning equipment, specifically an automatic alarm device for safe distance of personnel in production areas. Background Technology

[0002] Currently, in some production areas, there are instances of continuously operating live equipment. During this process, workers occasionally exhibit negligence, complacency, and a lack of awareness regarding safety, habitually relying on conventional thinking to address problems. This leads to insufficient identification of potential hazards and sources of danger during operations, and a lack of awareness or even complete unawareness of potential disasters. Consequently, accidents such as accidentally entering live areas, climbing live poles, or touching live conductors occur, causing incalculable losses to personnel, the power grid, and equipment. Therefore, installing automatic safety distance alarm devices in work areas is particularly necessary.

[0003] Currently available automatic personnel safety distance alarm devices have some limitations in practical applications. Firstly, some devices cannot adjust the length of the warning tape according to the span of the safety zone boundary during installation, meaning they cannot adapt to areas of different sizes. Secondly, the height of these warning tapes is fixed, and users cannot adjust the height according to specific circumstances, which limits their applicability in different scenarios. Therefore, this utility model provides an automatic personnel safety distance alarm device for production areas to solve the aforementioned problems. Utility Model Content

[0025] In order for this device to monitor the safety distance boundary of different spans and to install and fix the warning tape 29 of different lengths, a bidirectional lead screw 3 is fixedly installed at the output end of the first motor 2. A threaded block 4 is installed on the surface thread of the bidirectional lead screw 3. In order to ensure that the threaded block 4 can move stably inside the base 1, a moving groove 5 is opened inside the base 1. The threaded block 4 is slidably installed inside the moving groove 5, and the threaded block 4 is fixedly connected to the movable seat 6.

[0026] In order to adjust the height of the warning strip 29 to meet the needs of different scenarios, the lifting assembly includes a threaded rod 15 rotatably installed inside the movable rod 14. A third bevel gear 16 is fixedly installed at the bottom end of the threaded rod 15. The surface of the threaded rod 15 is threadedly connected to the lifting rod 17. In order to ensure that the lifting rod 17 can be raised and lowered stably, a slider 18 is fixedly installed on the surface of the lifting rod 17. A groove 19 is opened inside the movable rod 14, and the slider 18 is slidably installed inside the groove 19.

[0027] The drive assembly includes a second motor 7 fixedly mounted on the surface of the movable seat 6. A first rotating shaft 8 is fixedly mounted on the output end of the second motor 7. A first bevel gear 9 is fixedly mounted on the surface of the first rotating shaft 8. A second rotating shaft 11 is slidably sleeved on the surface of the first rotating shaft 8. A second bevel gear 13 is fixedly mounted on the end of the second rotating shaft 11 away from the first bevel gear 9. Two sets of third bevel gears 16 are provided, and the two sets of third bevel gears 16 mesh with the first bevel gear 9 and the second bevel gear 13 respectively. In order to ensure that the second rotating shaft 11 rotates stably with the first rotating shaft 8, a limiting block 10 is fixedly mounted on the surface of the first rotating shaft 8. A limiting groove 12 is opened on the surface of the second rotating shaft 11, and the limiting block 10 and the limiting groove 12 are slidably connected.

[0028] The alarm triggering component includes a spring groove 22 inside the connecting frame 21. A spring 23 is fixedly installed inside the spring groove 22. A movable plate 24 is fixedly installed at one end of the spring 23. A trigger switch 25 is fixedly installed on the side wall of the spring groove 22 away from the movable plate 24. A connecting plate 26 is fixedly installed on the side of the movable plate 24 away from the spring 23. A warning strip 29 is fixedly connected to the surface of the connecting plate 26. An installation slot 27 is opened inside the connecting plate 26. Both ends of the warning strip 29 are fixedly installed with plugs 28. The plugs 28 are plugged into the installation slot 27. The audible and visual alarm 20 is electrically connected to the trigger switch 25 through a wire.

[0029] The working principle of this utility model is as follows: The device is placed at a safe distance from live equipment within the production area. The base 1 is fixedly installed using the mounting block 30 and mounting holes. The first motor 2 is started, and its output rotates, driving the bidirectional lead screw 3 to rotate, which in turn moves the threaded block 4 within the moving groove 5, causing the movable seat 6 to move. This, in turn, moves the movable rod 14. The distance between the two sets of connecting plates 26 is adjusted so that warning tapes 29 of different lengths can be installed in the mounting slot 27. After adjusting the distance between the movable rods 14 as needed, the insert block 28 is inserted into the mounting slot 27 to fix the warning tape 29 in place. The second motor 7 is started, and its output rotates, driving the first rotating shaft 8 to rotate, causing the first bevel gear 9 to rotate. The limiting block 10 and limiting groove 12 allow the second rotating shaft 11 to rotate with the first rotating shaft 8. This drives the second bevel gear 13 to rotate, and the third bevel gear 16 meshes with the first bevel gear 9 and the second bevel gear 13, causing both sets of third bevel gears 16 to rotate, which in turn drives the threaded rod 15 to rotate. The threaded rod 15 is threadedly connected to the lifting rod 17. As the threaded rod 15 rotates, the lifting rod 17 moves, which drives the connecting frame 21 to rise and fall, thereby adjusting the height of the warning tape 29 to meet the needs of different scenarios. After the height of the warning tape 29 is adjusted, if personnel in the production area enter the danger zone, they will hit the warning tape 29, which will pull on the warning tape 29, causing the connecting plate 26 to move. This causes the movable plate 24 to move towards the trigger switch 25 within the spring groove 22. The spring 23 is stretched, causing the movable plate 24 to continue moving and press against the trigger switch 25. At this time, the audible and visual alarm 20 will be activated, emitting an alarm sound and flashing lights to warn personnel in the area.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
