Description

Technical Field

[0001] The utility model relates to the technical field of fire alarms, and in particular to a fire alarm based on cloud services. Background Art

[0002] A fire alarm is a device used to detect fires and sound alarms. It senses the smoke, heat or other flame characteristics generated by the fire and promptly sends out sound and light alarm signals to remind people to take fire prevention measures to avoid the spread of fire. It is an important part of fire safety.

[0003] A fire alarm is a device used to detect fires and sound an alarm. Its working principle mainly includes the following aspects: fire detection, signal transmission, signal processing, alarm triggering, etc. The fire alarm is equipped with fire detectors such as smoke sensors, temperature sensors, etc. These sensors can monitor the surrounding environment in real time and detect signs of fire. Signal transmission is the transmission of the signal to the alarm host via wired or wireless means. When the alarm host receives the fire signal, it will process it, such as confirming the type of fire, the location of the fire, etc. When the host confirms the fire, it will activate the alarm device, such as sending out sound and light alarm signals, to remind people to take escape measures in time. Through these links, the fire alarm can detect fires in time, remind people to take measures, and assist in controlling the spread of fire to ensure personal and property safety.

[0004] However, the host of a general fire alarm is usually installed indoors. If a fire occurs, it is difficult to transmit the fire situation to the outside world, and it is also difficult to call the fire alarm in the first time. At the same time, the fire alarm is generally installed at a high place in the room. When a fire occurs, the flame may cause a big fire due to the combustion of objects. The fire alarm on the top may be damaged due to the burning of the flame and the high temperature, increasing the subsequent maintenance cost. In view of this, a fire alarm based on cloud service is provided to overcome the above defects. Utility Model Content

The magnetic strips on the front side of the rotating plate and the magnetic strips on the rear side of the rotating plate are magnetically fixed to each other. When the rotating plate wraps the alarm, the magnetic strips on the top of the rotating plate are magnetically attracted to fix the rotating plates to each other to prevent flames or external wind from separating the two rotating plates.

A magnetic strip 12 is welded at the edge of the extension plate 11. A fixing plate 13 is welded at the tops of the front and rear sides of the bottom plate 9. The fixing plate 13 The inner end surface is fixed with a liquid nitrogen transmitter 14 by bolts, a liquid nitrogen bottle 15 is arranged at the outer input end of the liquid nitrogen transmitter 14, an insulating layer 18 is fixed to the top of the fixing block 17 by glue, the inner side of the insulating layer 18 is coated with an electric wire 20, a second metal sheet 19 is welded to the bottom of the insulating layer 18, an edge of the rotating plate 10 is in contact with an edge of the fixing plate 13, an output end of the electric wire 20 is in contact with the second metal sheet 19, and a bottom of the second metal sheet 19 is in magnetic contact with a top of the first metal sheet 16, so that when the electric wire 20 is powered off, the magnetism between the first metal sheet 16 and the second metal sheet 19 disappears, allowing the rotating plate 10 to cover the outer side of the alarm body 1, thereby reducing the damage to the alarm body 1 caused by the flame and reducing the maintenance cost.

[0022] As a further implementation scheme of the above technical scheme: the power supply module 2 supplies power to the sensor module 3, the data processing unit 4, the remote control unit 5, the remote receiving unit 6 and the alarm module 7 inside the alarm body 1, the sensor module 3 is a smoke sensor, the sensor module 3 is electrically connected to the data processing unit, the data processing unit 4 is electrically connected to the remote control unit 5, the remote control unit 5 is electrically connected to the cloud service terminal 8, the cloud service terminal 8 is electrically connected to the remote receiving unit 6, and the remote receiving unit 6 is electrically connected to the alarm module 7. The fire situation detected by the sensor module 3 inside the alarm body 1 can be transmitted to the cloud service terminal 8 through the remote control unit 5, so that the terminal operator can select the corresponding processing method according to the fire situation and record the fire situation in the cloud service storage.

[0023] As a further implementation scheme of the above technical scheme: the rotating plate 10 is divided into a left rotating plate 10 and a right rotating plate 10, the top extension plate 11 of the rotating plate 10 on the left side of the bottom plate 9 is fixed to the front side of the top of the rotating plate 10, and the top extension plate 11 of the rotating plate 10 on the right side of the bottom plate 9 is fixed to the right side of the top of the rotating plate 10, the areas of the extension plates 11 on the front and rear sides of the top of the rotating plate 10 are the same, and the front and rear lengths of the extension plates 11 on the front and rear sides of the top of the rotating plate 10 are both half of the front and rear lengths of the rotating plate 10, so that the two rotating plates 10 rotate downward by gravity to wrap the alarm body 1.

The magnetic strip 12 on the front side of the rotating plate 10 and the magnetic strip 12 on the rear side of the rotating plate 10 are magnetically fixed to each other. When the rotating plate 10 wraps the alarm, the magnetic strip 12 at the top of the rotating plate 10 is magnetically attracted to fix the rotating plates 10 to each other to prevent the flame or external wind from separating the two rotating plates 10.

Through the principle of forming magnetism when metal is electrified, before a fire occurs, the second metal sheet 19 magnetically attracts the first metal sheet 16, exposing the alarm body 1 to the outside. When a fire occurs, the wire 20 is powered off, and the magnetism of the second metal sheet 19 and the first metal sheet 16 disappears, allowing the rotating plate 10 to naturally rotate downward and cover the outside of the alarm body 1.

The sensor module 3 monitors the surrounding environment in real time. When the sensor module 3 detects the smoke concentration, it transmits it to the data processing unit 4. When the data processing unit 4 detects that the smoke concentration is high, the data processing unit 4 sends the data to the cloud service terminal 8 through the remote control unit 5. The cloud service terminal 8 then sends the command to the remote receiving unit 6. The remote receiving unit 6 starts the alarm module 7 to let the alarm body 1 sound an alarm. When the fire is large, the cloud service terminal 8 sends a signal to the remote receiving unit 6 to the second The metal sheet 19 issues a power-off command. At this time, the fixed block 17 fixed on the ceiling and the wire 20 inside the insulating layer 18 are powered off, and the magnetism between the second metal sheet 19 and the first metal sheet 16 disappears. The rotating plates 10 at the top of the left and right sides of the bottom plate 9 rotate downward until the two extension plates 11 on the top of the rotating plate 10 are engaged with each other, and the magnetic strips 12 on the edges of the extension plates 11 are magnetically attracted to each other to fix the extension plates 11. Then, the liquid nitrogen emitters 14 located on the inner sides of the fixed plates 13 on the front and rear sides of the bottom plate 9 spray the liquid nitrogen in the outer liquid nitrogen bottle 15 on the edge of the alarm body 1, thereby quickly reducing the temperature of the space inside the rotating plate 10 and the fixed plate 13 caused by the fire, and reducing the damage rate of the alarm body 1 in the fire.
