Description

Technical Field

[0001] This utility model relates to the field of alarm device technology, and more specifically, it relates to a high-risk dust alarm device. Background Technology

[0002] Excessive dust in the air can easily breed bacteria and viruses, which is extremely detrimental to health and can also cause great harm to skin health. Dust pollution directly threatens people's lives, especially since being in a dust-polluted environment can cause various cardiovascular and respiratory diseases. Dust pollution has the greatest impact on the elderly and children. Currently, monitoring and warning devices for detecting the dust content in the air are usually installed in some areas with high dust pollution.

[0003] Dust alarm devices are a common type of dust content monitoring and warning equipment. When a dust alarm detects that the dust content exceeds the standard, it will sound an alarm to remind people passing by. At the same time, the dust alarm is equipped with a display screen to observe the detected dust in real time. However, in order to better detect dust content, dust alarm devices are usually fixed in a high place. In order to ensure the accuracy of dust detection, the detection device of the dust alarm needs to be cleaned regularly and the dust alarm device itself needs to be maintained. Fixing the dust alarm device in a high place makes cleaning and maintenance very inconvenient.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] In one possible embodiment, please refer to Figure 1 As shown, a high-risk dust alarm device includes a mounting base 1 and an alarm device body 2. The alarm device body 2 is equipped with a display screen 3 and a detection device 4. The detection device 4 is located at the lower end of the alarm device body 2 and is used to detect the dust content in the air. The display screen 3 can display the dust content detected by the alarm device body 2 for easy observation by passers-by. The mounting base 1 is fixedly connected to the wall. A lifting platform 5 is slidably installed in the mounting base 1. The alarm device body 2 is engaged with the mounting base 1. By detaching the alarm device body 2 and the lifting platform 5, it is easy to disassemble and install the alarm device body 2, and to clean and maintain it. The mounting base 1 is equipped with a lifting mechanism for raising and lowering the lifting platform 5. Therefore, when it is necessary to disassemble the alarm device body 2, it is only necessary to lower the lifting platform 5 by the lifting mechanism, without the need to climb a ladder, making the installation and disassembly of the alarm device body 2 more convenient and safe.

[0021] For further details, please refer to Figure 1 As shown, the lifting mechanism includes a drive motor 20 installed in the mounting base 1 and a screw 21 fixedly connected to the output end of the drive motor 20. The mounting base 1 is provided with a square groove 22 that slides with the lifting platform 5. The square groove 22 can limit the axial movement of the lifting platform 5. The lifting platform 5 is threadedly engaged with the screw 21. The drive motor 20 drives the screw 21 to rotate, which in turn drives the lifting platform 5, which is threadedly connected to the screw 21, to slide up and down in the square groove 22. This facilitates the maintenance and replacement of the alarm device body 2 that is attached to the lifting platform 5.

[0022] For further details, please refer to Figure 2 , Figure 3 and Figure 4 As shown, the lifting platform 5 is provided with a locking hole 6, and a limiting member 7 is provided inside the locking hole 6 to slide with the locking hole 6. The limiting member 7 includes an adjusting block 11 that slides with the lifting platform 5 and a limiting block 12 that is fixedly connected to the adjusting block 11. The alarm device body 2 is provided with a locking block 8 that slides with the locking hole 6. The locking block 8 includes a connecting block 9 and an abutting block 10 that is fixedly connected to the connecting block 9. The upper surface of the abutting block 10 abuts against the lower surface of the limiting block 12. The contact between the locking block 8 and the limiting member 7 ensures the stability of the alarm device body 2 and the lifting platform 5 during installation. The locking block 10 is provided with a guide surface 13. The lifting platform 5 is provided with an adjustment groove 14 that slides with the limiting member 7. A sliding groove 15 that communicates with the adjustment groove 14 is provided on one side of the lifting platform 5. An adjustment plate 16 that extends out of the sliding groove 15 and slides with the sliding groove 15 is fixedly connected to one end of the adjustment block 11. A spring 17 is fixedly connected between the adjustment plate 16 and the sliding groove 15.

[0023] For details, please refer to Figure 2 , Figure 3 and Figure 4 As shown, when the alarm device body 2 needs to be installed, by aligning and engaging the locking block 8 of the alarm device body 2 with the locking hole 6 on the lifting platform 5, the abutting block 10 of the locking block 8 will abut against the limiting block 12 of the limiting member 7. Under the action of the guide surface 13, the limiting member 7 will slide into the adjusting groove 14. When the abutting block 10 is fully engaged in the locking hole 6, the limiting member 7, having lost the force of the abutting block 10, will rebound under the action of the spring 17, causing the lower surface of the limiting block 12 to contact the upper surface of the abutting block 10. The surfaces abut against each other, thereby limiting the alarm device body 2 on the lifting platform 5. When it is necessary to remove the alarm device body 2 from the lifting platform 5, force is applied to the adjusting plate 16. The movement of the adjusting plate 16 causes the limiting member 7 to slide into the adjusting groove 14, so that the limiting member 7 loses its force on the locking block 8. This allows the locking block 8 to disengage from the locking hole 6, releasing the force on the adjusting plate 16. The limiting member 7 will rebound under the action of the spring 17 and slide back into the locking hole 6.

[0024] For further details, please refer to Figure 2 and Figure 4 As shown, the lifting platform 5 is equipped with a stop block 18 that engages with the slide groove 15. The stop block 18 and the lifting platform 5 are connected by a pull rope 19. When the alarm device body 2 is inserted into the lifting platform 5, the stop block 18 is inserted into the slide groove 15, thereby abutting against the adjusting plate 16, limiting the adjustment plate 16, preventing the adjusting plate 16 from shifting, and ensuring the stability of the installation of the alarm device body 2 and the lifting platform 5.

[0025] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
