[0001] The utility model relates to the technical field of alarm devices, in particular to an intelligent fire alarm device. Background Art

[0002] Fire refers to a catastrophic burning phenomenon that is out of control in time or space. With the increasing frequency of fires, fire prevention and alarm are particularly important. Therefore, automatic fire alarm devices are often used in some buildings.

[0003] After searching, the patent with the authorization announcement number CN220455922U proposes an intelligent fire alarm device, including a shell, an alarm mechanism, a protection mechanism and a driving mechanism. The side wall of the shell is provided with a mounting groove; the alarm mechanism is installed in the mounting groove, and the alarm mechanism is used to alarm when a fire occurs; the protection mechanism includes a lifting rod movably installed in the mounting groove and a protective cover connected to the lifting rod; the output end of the driving mechanism is connected to the lifting rod for driving the lifting rod to move up and down during operation. This intelligent fire alarm device replaces the traditional intelligent fire alarm device, avoiding the problem that the high temperature after a fire occurs damages the internal components of the alarm device, and thus the alarm cannot be continuously sounded. The following problems exist in this technical solution:

[0004] In the prior art, since the alarm mechanism is located inside the housing, and it is not convenient to extend outside the housing when monitoring a fire, the monitoring effect of the fire is affected, and there is a hidden danger that the fire cannot be monitored in time, which reduces the safety level;

[0005] In view of the above problems, the present utility model document proposes an intelligent fire alarm device. Utility Model Content

[0006] The utility model provides an intelligent fire alarm device, which solves the disadvantages in the prior art that the alarm mechanism is located inside the shell and is not convenient to extend outside the shell when monitoring the fire, which in turn affects the fire monitoring effect, has the hidden danger of not being able to monitor the fire in time, and reduces the safety level.

[0007] The utility model provides the following technical solutions:

[0008] An intelligent fire alarm device, comprising:

[0009] A fireproof box, wherein a mounting groove is provided inside the fireproof box, and fixing plates are fixedly provided on both sides of the fireproof box, and each fixing plate has two fixing holes on the top thereof;

[0010] A monitoring and alarm mechanism is arranged in the fireproof box for monitoring and alarming fire;

[0011] The telescopic protection mechanism is arranged in the fireproof box and is used for telescoping and protecting the monitoring alarm mechanism.

[0012] In a possible design, the monitoring alarm mechanism includes a mounting plate, which is slidably connected to the inside of a mounting groove, a buzzer alarm is fixedly mounted on the bottom side of the mounting plate, and a temperature sensor is arranged on the bottom side of the mounting plate.

[0013] In a possible design, a smoke sensor and a flame sensor are respectively fixedly mounted on the bottom side of the mounting plate.

[0014] In a possible design, the telescopic protection mechanism includes an electric push rod, which is fixedly mounted on the top side of the inner wall of the mounting groove, and the output end of the electric push rod is fixed to the top side of the mounting plate, and two telescopic rods are fixedly arranged between the top side of the mounting plate and the top side of the inner wall of the mounting groove.

[0015] In a possible design, connecting rods are fixedly provided on the bottom side of the mounting plate in pairs symmetrically, and fire protection nets for protecting the monitoring alarm mechanism are fixedly provided at the bottom ends of the four connecting rods.

[0016] In a possible design, connecting plates are fixedly installed on both sides of the fire protection net, and two slots for connecting the connecting plates are opened on the bottom side of the fireproof box. Two magnets are arranged on the top side of each connecting plate, and two iron blocks attracted by the magnets are arranged on the top side of the inner wall of each slot.

[0017] In the present application, when in use, first use the mounting bolts to penetrate the fixing holes on the fixing plate to stably fix the fireproof box in the area that needs to be monitored, thereby enhancing convenience. When the device is in working condition, the electric push rod runs to drive the mounting plate and the monitoring alarm mechanism to move downward until the monitoring alarm mechanism is completely separated from the mounting groove and extends out of the outside of the fireproof box. At this time, the monitoring alarm mechanism is exposed to the outside, which is conducive to the execution of fire monitoring tasks. The setting of the telescopic rod ensures the stability of the mounting plate during the movement and plays a certain guiding role. The monitoring alarm mechanism can be used to monitor the fire in real time. If a fire is detected, the electric push rod can drive the mounting plate and the monitoring alarm mechanism thereon to the fireproof box. Inside the fire box, the fire protection net is tightly covered under the mounting plate through the connection between the connecting plate and the card slot and the adsorption of the magnet and the iron block, which is beneficial to protect the monitoring alarm mechanism and prevent burning objects from hitting the monitoring alarm mechanism and causing damage to it when the fire is large. Therefore, when monitoring the fire, the monitoring alarm mechanism is convenient to extend outside the fireproof box to avoid affecting the monitoring effect of the fire and the hidden danger of not being able to monitor the fire in time, thereby improving the safety level. The adsorption and fixation of the magnet and the iron block can prevent the electric push rod from being powered off due to the fire, which causes the fire protection net to fall automatically, further strengthening the protection, so as to adapt to the protection of harsh scenes and improve the use effect.

[0018] While the monitoring alarm mechanism is exposed to the outside of the fireproof box, the temperature sensor on the bottom side of the mounting plate is used to monitor the ambient temperature in real time. When the temperature exceeds the preset safety threshold, the alarm will be triggered. The smoke sensor is used to detect the smoke concentration in the air. When the smoke concentration reaches or exceeds the set threshold, the alarm will also be triggered. The flame sensor is used to directly detect the flame. Once the flame is detected, the alarm will be triggered immediately. When the buzzer alarm receives an alarm signal from any sensor, it will emit a loud alarm to remind people to pay attention to the fire situation. Since the entire monitoring alarm mechanism is connected to the hardware microcontroller set up in the outside world, the alarm upper limit can be set using the buttons on the controller. Both temperature and smoke concentration can be used, and the microcontroller The data will be transmitted to the corresponding LCD screen, and the temperature and smoke concentration will be displayed through the LCD screen. The control circuit uses a single-chip microcomputer for data processing and control signal output. In the software part, the smoke concentration is the analog quantity collected by the smoke sensor, which is converted into a digital quantity by ADC. The temperature data is obtained by reading the first two bytes of the memory by the single-chip microcomputer and calculating. The flame signal is judged by whether the pin of the flame sensor connected to the single-chip microcomputer is at a low level. The LCD screen displays the temperature and smoke concentration by writing command functions and writing data functions. Furthermore, the device realizes the functions of collecting, processing, and displaying sensor data, can monitor the changes of parameters such as smoke, temperature, and flame in real time, and improves the use effect.

[0019] In the utility model, the intelligent fire alarm device can monitor the ambient temperature in real time and detect the smoke concentration in the air through the monitoring alarm mechanism, can directly detect the flame, and at the same time send out a loud alarm sound to remind people to pay attention to the fire situation;

[0020] In the utility model, the intelligent fire alarm device can drive the monitoring alarm mechanism to extend and be stored outside and inside the fireproof box through the telescopic protection mechanism, which is conducive to monitoring the fire situation. At the same time, the monitoring alarm mechanism can be protected to prevent burning objects from hitting the monitoring alarm mechanism and causing damage to it when the fire situation is large;

[0021] In the utility model, the monitoring alarm mechanism can be easily extended outside the fireproof box when monitoring the fire, so as to avoid affecting the monitoring effect of the fire and the hidden danger of not being able to monitor the fire in time, thereby improving the safety level. At the same time, it can prevent the electric push rod from being powered off due to the fire, causing the fire protection net to automatically fall, so as to adapt to harsh scene protection.
