Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, specifically a portable audible and visual early warning alarm device. Background Technology

[0002] In the field of fire protection, audible and visual alarm devices are one of the important equipment to ensure fire safety. However, some existing audible and visual alarm devices have many shortcomings in practical applications and cannot meet the special needs of fire protection work.

[0003] First, some existing audible and visual warning alarm devices have limitations in their structural design. They are often not equipped with suitable supports, which is a significant drawback in firefighting scenarios. Taking fire rescue in open areas such as highways as an example, when a fire or other emergency occurs, these devices often need to be placed on the side of the road or other key locations for early warning. However, due to the lack of supports, their height and visibility are greatly limited, making them not conspicuous enough in complex on-site environments and unable to effectively attract the attention of passing vehicles and pedestrians. This may lead to delays in rescue operations or cause unnecessary dangers. For example, when conducting fire rescue on highways, passing vehicles travel at high speeds. If the alarm device is placed too low or not prominent, it may not be noticed by drivers in time, increasing the risk of traffic accidents and affecting the smooth progress of rescue work.

[0004] Secondly, the alarm functions of these devices are relatively simple, usually only having an alarm sound and lacking a brief voice prompt function. In fire-fighting work, different scenarios require different information transmission, and relying solely on alarm sounds is insufficient to accurately convey key information, such as brief and clear voice prompts at the fire scene. Existing devices cannot meet this requirement, which affects the on-site personnel's accurate judgment and response to dangerous situations, reducing the efficiency and safety of fire-fighting work.

[0005] In addition, existing audible and visual warning alarm devices are not perfect in terms of light source design. They lack an integrated design, and their light source may be composed of multiple scattered components. This not only makes installation and maintenance complicated, but also makes them prone to failure in fire-fighting operations. In fire scenes or other emergency situations, due to the influence of harsh environments such as smoke and dust, some components of non-integrated light sources may fail, resulting in incomplete or unstable light signals, affecting their effectiveness as warning signals. Moreover, the non-integrated light source design is not conducive to the concentration and optimization of light signals, making it difficult to adjust the intensity, color, and flashing mode of the light according to different fire scenarios. It cannot provide targeted visual warnings and cannot meet the complex and ever-changing warning needs of fire scenes.

[0006] Furthermore, existing audible and visual early warning alarm devices also have shortcomings in terms of integration, mobility, and adjustability. The connections between their various components are not compact enough, resulting in low integration and a large overall size that is inconvenient to operate. In firefighting operations, it is often necessary to quickly adjust the position of the devices according to changes in the spread of fire and rescue operations, but existing devices are not easy to move and deploy quickly, and are easily damaged during movement. At the same time, they lack flexibility in adjusting sound and light signals and cannot be adjusted in a timely manner according to on-site environmental conditions and rescue needs, thus limiting their applicability in firefighting work.

[0007] However, existing technologies have the following problems in practical use:

[0008] When the overall device is in use, the lighting control method is not flexible enough. It can generally only provide simple fixed light signals, such as a single color constant light or a simple flashing mode. It cannot provide diversified light signals according to different warning levels and environmental needs. The sound signal cannot be effectively transmitted to the required range, resulting in some areas not receiving effective alarm information, which affects the warning effect. The support and marking components are inadequate. They lack effective limit and branch structures. In outdoor or complex environments, they are prone to structural deformation or damage due to external forces such as wind and collisions, which affects the stability and service life of the device. Summary of the Invention

[0009] (a) Technical problems to be solved

[0010] To overcome the aforementioned shortcomings of the prior art, this utility model provides a portable audible and visual early warning alarm device, which solves the problems in the prior art:
