Description

Technical Field

[0001] This utility model relates to the field of early warning device technology, and in particular to an early warning device for hot work operations where personnel are absent. Background Technology

[0002] Hot work refers to operations such as welding, cutting, and heating that may cause a fire due to the generation of sparks, flames, or high temperatures. These operations are usually carried out in industrial, construction, and maintenance fields and are inherently dangerous. Therefore, strict safety measures must be taken, and necessary fire-fighting equipment, such as fire extinguishers and fire hydrants, must be provided at the work site and ensured to be readily available.

[0003] However, during hot work operations, it is necessary to assign dedicated personnel to monitor the site and promptly detect and handle emergencies. In actual operations, personnel may leave the site briefly, and the equipment may be left unpowered, which could easily lead to danger. Furthermore, some existing equipment used in hot work operations is not designed for use by people of different heights, and the height of the equipment cannot be adjusted in different scenarios, which reduces the effectiveness of the equipment in hot work operations. Therefore, it is necessary to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pre-warning device for hot work operations where personnel are not present.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hot work evacuation warning device includes a base, a support frame vertically fixed to the top of the base, a lifting plate vertically slidably connected to the surface of the support frame, a connection box and a control box fixedly connected to the surface of the lifting plate, the control box being located on top of the connection box, a sliding mechanism for the lifting plate on the surface of the base, a mounting plate horizontally fixedly connected inside the support frame, the mounting plate being located on top of the support frame, a human body sensing module mounted on the surface of the mounting plate, casters mounted at the four corners of the base, and two fire extinguishers placed on the top of the base. The device's ability to slide the lifting plate up and down allows it to be used by people of different heights and in different usage scenarios, thus improving its effectiveness. Furthermore, the real-time monitoring by the human body sensing module allows the device to provide a warning when someone leaves the area, thereby enhancing its safety.

The slider is fixedly connected to the surface of the lifting plate. A lead screw is rotatably connected inside the support frame, with its upper and lower ends rotatably connected to the surfaces of the two horizontal plates. The slider is slidably fitted onto the surface of the lead screw. The slider and lead screw cooperate to limit the vertical sliding of the alarm, thereby facilitating the adjustment of the height of multiple sockets and switches.

[0008] Furthermore, fixed blocks are fixedly connected to both ends of the support frame surface, and a rotating shaft is rotatably connected to the support frame surface. The rotating shaft is horizontally positioned, and its two ends are respectively rotatably fitted inside the two fixed blocks.

The two connecting plates 22 are fixedly connected to the surfaces of the two slide bars 23 and to both ends of the surface of the lifting plate 2. Two horizontal plates 14 are horizontally fixedly connected inside the support frame 11. A slider 21 is vertically slidably connected between the two horizontal plates 14 and fixedly connected to the surface of the lifting plate 2. A lead screw 43 is rotatably connected inside the support frame 11. The upper and lower ends of the lead screw 43 are rotatably connected to the surfaces of the two horizontal plates 14. The slider 21 is slidably fitted onto the surface of the lead screw 43. The slider 21 cooperates with the lead screw 43 to limit the vertical sliding of the alarm 3, thereby facilitating the adjustment of the height of the multiple sockets 25 and the switch 28.

[0021] Reference Figures 1-3 In a preferred embodiment, fixed blocks 15 are fixedly connected to both ends of the surface of the support frame 11. A rotating shaft 41 is rotatably connected to the surface of the support frame 11. The rotating shaft 41 is horizontally arranged, and its two ends are respectively rotatably sleeved inside the two fixed blocks 15. Turntables 4 are rotatably connected to both sides of the surface of the support frame 11. The two turntables 4 are respectively fixedly connected to the two ends of the rotating shaft 41. A worm gear 42 is rotatably connected to the surface of the support frame 11. The worm gear 42 is sleeved on the surface of the rotating shaft 41.

[0023] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In actual use, by setting the lifting plate 2 to slide up and down, the device can be used for people of different heights and in different usage scenarios, thereby improving the effectiveness of the device. At the same time, in conjunction with the real-time monitoring of the human body sensing module 31, the device can provide a warning when someone leaves, thereby improving the safety of the device. When in use, either of the two turntables 4 can be manually rotated to rotate the rotating shaft 41 and the worm gear 42. Under the connection of the worm wheel 44, the lead screw 43 will rotate, which will cause the slider 21 to slide up and down, and at the same time, the lifting plate 2 will slide up and down, thereby allowing the multiple sockets 25 on the surface of the connecting box 24 and the switches 28 and the pointers on the surface of the control box 26 to move. The height of the indicator light 29 is adjustable, making it more convenient to use and suitable for different groups of people. The human body sensor module 31 on the device can detect the personnel at the hot work site in real time. If no personnel are detected within 90 seconds, the human body sensor module 31 will send a signal to the controller, which will then drive the alarm 3 to respond, reminding the personnel to return to the site. If the personnel return within two minutes, the alarm will be deactivated after being detected by the human body sensor module 31. If the personnel still do not return after two minutes, the device will activate a secondary alarm, and the alarm 3 on the top of the device will be activated to remind nearby personnel. At the same time, the power supply to the hot work site will be cut off. After 10 seconds, the system will automatically call the relevant personnel to handle the situation via telephone, thereby improving the safety of the device.
