[0002] A fire is a catastrophic combustion phenomenon that is out of control in time or space. While using fire, people constantly summarize the patterns of fire occurrences and try to minimize fires and their harm to humans. When a fire occurs, people need to escape safely and quickly. Generally, alarm devices are installed indoors in public places to alert the fire department in time. However, current alarm devices cannot transmit fire scene information to the outside during a fire, and cannot provide effective information for firefighters to deploy before entering the fire scene. Even if the alarm device is equipped with a camera, if it is not used for a long time, the camera may be covered by dust, which will affect the shooting effect during a fire. It also cannot work normally under high temperature. Summary of the Invention

[0019] Please refer to Figures 1-4. This utility model provides the following technical solution: It includes an alarm body 1, a base 11, and a mounting plate 12. Several lamps 13 are arranged on the outside of the alarm body 1. A connecting cavity 2 is opened in the inner cavity of the base 11, and several shooting components 3 are arranged on the outside of the base 11. A control component 21 and a control sensor 22 are arranged in the inner cavity of the connecting cavity 2. A protective shell 31 is arranged on one side of the shooting component 3. Several drivers 32 are installed at the bottom of the mounting plate 12. A transmission component is arranged between the driver 32 and the protective shell 31. The driver 32 drives the protective shell 31 to rotate and connect with one side of the base 11 through the transmission component.

[0020] In this implementation scheme: the main structure of the alarm is composed of an alarm body 1, a base 11, and a mounting plate 12. Several lights 13 are installed on the outside of the alarm body 1. In this invention, the lights 13 are colored lights, which quickly locate the alarm upon arrival at the fire scene and then determine the ignition point. A connecting cavity 2 is provided inside the base 11, and several camera components 3 are installed on the outside of the base 11. By setting up the camera components 3, after the alarm is activated, the camera components 3 are activated simultaneously to capture images of the surrounding environment of the fire scene and transmit them to the monitoring equipment, allowing firefighters to understand the internal situation before arriving at the fire scene. A control component 2 is installed inside the connecting cavity 2. The control sensor 22 and control component 21 together form a drive assembly for the protective housing 31. A protective housing 31 is provided on one side of the imaging component 3. Under normal circumstances, the protective housing 31 protects the imaging component 3, preventing dust from covering its surface and affecting the clarity of the images captured in the event of a fire. Several drivers 32 are installed at the bottom of the mounting plate 12. A transmission assembly is provided between the drivers 32 and the protective housing 31. The drivers 32 drive the protective housing 31 to rotate and connect it to one side of the base 11 via the transmission assembly. The drivers 32 and the transmission assembly together form a drive assembly for the protective housing 31. Under normal circumstances, the protective housing 31 covers... Outside the imaging component 3, when a fire occurs, the alarm body 1 receives signals from sensors, such as smoke detectors or heat detectors, which are distributed throughout the monitoring area and electrically connected to the control component 21 in this invention. When the alarm body 1 starts working, the control component 21 and the control sensor 22 simultaneously activate the lamp 13 and the driver 32. The lamp 13 emits a relatively conspicuous colored light, and the driver 32 drives the pulley 33 at its output end to start rotating. This pulley 33 drives the pulley 33 mounted on one end of the protective housing 31 to rotate via the belt 331, thereby driving the protective housing 31 to rotate through the driver 32, causing the protective housing 31 covering the outside of the imaging component 3 to rotate. The imaging component 3 is exposed to the outside. At the same time, the imaging component 3 is activated through the control component 21 and the control sensor 22 to capture images of the situation inside the fire scene and transmit them to the external monitoring equipment in real time. This allows firefighters to have some understanding of the situation before entering the fire scene. Thus, this new device can capture images of the situation inside the fire scene at the same time as the alarm is triggered, assisting firefighters in understanding the fire scene situation in advance and providing effective information for rescue. The light fixture 13 can quickly locate the new device when entering the fire scene and use the location of the new device as a reference to quickly locate the ignition point. Under normal circumstances, the imaging component 3 should be protected to prevent dust from covering its surface and affecting the clarity of its images during a fire.

[0021] The transmission assembly includes two pulleys 33 disposed at the output end of the driver 32 and on one side of the protective housing 31. A belt 331 is disposed between the two pulleys 33, and the two pulleys 33 are connected by the belt 331. The two pulleys 33 and the protective housing 31 form a transmission assembly that drives the protective housing 31 in the event of a fire, thereby disarming the camera assembly 3.

[0022] The lamp 13, the shooting component 3 and the driver 32 are all electrically connected to the control sensor 22, and the control component 21 and the control sensor 22 are connected by wires; the lamp 13, the shooting component 3 and the driver 32 are controlled by the control sensor 22 and the control component 21 so that they start working in the event of a fire.

[0023] The base 11 is fixedly connected to the mounting plate 12. The mounting plate 12 has a wiring groove in its inner cavity, which is connected to the inner cavity of the connecting cavity 2. The base 11 and the mounting plate 12 are used to install the alarm body 1. The wiring groove facilitates the installation of the connecting wires of various components inside the connecting cavity 2.

[0024] The mounting plate 12 has several connecting parts 121 arranged at equal intervals around its four edges. The connecting parts 121 are integrated with the mounting plate 12. The mounting plate 12 is easy to install by providing several connecting parts 121.

[0025] The base 11 has a protective layer 23 embedded inside, and the connecting cavity 2 is opened inside the protective layer 23. By setting the protective layer 23, the components inside the connecting cavity 2 are protected when the temperature is high after a fire, so that the control component 21 and the control sensor 22 can work normally in a high-temperature environment.

[0026] Several shooting components 3 are installed at equal intervals on one side of the base 11. The base 11 is set as a frustum-shaped structure, and several belt connecting grooves 34 matching the shooting components 3 are opened on the outer side of the base 11. The opening of several belt connecting grooves 34 on the outer side of the base 11 facilitates the installation of several shooting components 3.

[0027] The working principle and usage process of this utility model are as follows: Under normal circumstances, the protective housing 31 covers the outside of the imaging component 3. When a fire occurs, the alarm body 1 receives signals from sensors, which can be smoke detectors or temperature sensors, all distributed throughout the monitoring area. These sensors are electrically connected to the control component 21 in this utility model. When the alarm body 1 starts working, the control component 21 and the control sensor 22 simultaneously activate the lamp 13 and the driver 32. The lamp 13 emits a relatively conspicuous colored light, and the driver 32 drives the pulley 33 at its output end to start rotating. This pulley 33 drives the pulley 33 installed at one end of the protective housing 31 to rotate through the belt 331, thereby driving the protective housing 31 to rotate through the driver 32. This causes the protective housing 31 covering the outside of the imaging component 3 to rotate, exposing the imaging component 3 to the outside. At the same time, the imaging component 3 starts working through the control component 21 and the control sensor 22 to capture images of the situation inside the fire scene and transmit them in real time to the external monitoring equipment. This allows firefighters to have some understanding of the situation inside the fire scene before entering, assisting them in understanding the internal conditions of the fire.
