[0002] Fire alarm devices are an indispensable safety device in buildings. When a fire occurs, the circuit may catch fire and the power may be cut off. Therefore, fire alarm devices need to be equipped with independent power supplies. Existing fire alarm devices generally use built-in batteries, but batteries are prone to spontaneous combustion during the charging and discharging process. Under the high temperature of a fire, batteries are more likely to spontaneously combust. The spontaneous combustion of batteries will not only further aggravate the fire, but also affect the normal operation of the fire alarm device. Utility Model Content

[0005] The power supply structure includes solar photovoltaic and storage battery, both of which are fixed on the roof, the solar photovoltaic is electrically connected to the storage battery, and the storage battery is electrically connected to the alarm structure through a cable;

[0006] The alarm structure includes a shell, a temperature sensor, a first buzzer, a light alarm, a smoke sensor, a second buzzer and a controller. The shell is connected to the building wall. The temperature sensor, the first buzzer, the light alarm, the smoke sensor and the second buzzer are arranged outside the shell. The temperature sensor, the first buzzer, the light alarm, the smoke sensor and the second buzzer are respectively connected to the controller signal. The controller is arranged inside the shell.

[0007] As a preferred solution, a connecting plate extends from the connection between the shell and the building wall, the connecting plate is provided with a through slot, a bolt is arranged in the through slot, and the bolt is threadedly connected to the building wall.

[0008] As a preferred solution, the signal output ends of the temperature sensor and the smoke sensor are signal-connected to the signal input end of the controller, the controller is a single-chip microcomputer, and the signal output end of the controller is signal-connected to the signal input ends of the light alarm, the first buzzer and the second buzzer.

[0009] As a preferred solution, the light alarm is provided with a reflector, which is connected to the inside of the shell and is arranged on the back side of the light source. A filter cover is also arranged on the outside of the light source.

[0010] The beneficial effects achieved by the utility model are:

[0011] The utility model uses solar photovoltaic power generation and stores it in a battery, which then supplies power to the alarm structure, that is, a self-powered structure is adopted, which can avoid the alarm device from not working properly due to power outages caused by fire; in addition, the battery is arranged outside the building, which can reduce the possibility of fire caused by spontaneous combustion of the battery.

[0012] The utility model is provided with a first buzzer and a second buzzer. When a fire occurs, the smoke sensor senses the smoke concentration. When the smoke concentration exceeds a preset value, the first buzzer alarms. If the temperature sensor does not detect an obvious temperature rise at this time, the alarm stops. If the temperature sensor detects a continuous high temperature, the second buzzer and the first buzzer alarm at the same time, thereby improving the accuracy of the alarm and increasing the alarm volume.

[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0020] like Figure 1-Figure 3As shown, the utility model discloses a novel self-powered building fire alarm device, including a power supply structure 1 and an alarm structure 2, wherein the power supply structure 1 is used to supply power to the alarm structure 2. The power supply structure 1 is arranged outside the building, and the power supply structure 1 includes a solar photovoltaic 11 and a battery 12, wherein the solar photovoltaic 11 is arranged facing the sun, and as an implementation mode, the solar photovoltaic 11 and the battery 12 are both fixedly arranged on the roof, and the solar photovoltaic 11 and the battery 12 are electrically connected, and the electric energy converted by the solar photovoltaic 11 is stored in the battery 12, and the battery 12 is electrically connected to the alarm structure 2 through a cable 3, thereby supplying power to the alarm structure 2.

[0021] The alarm structure 2 includes a housing 21, a temperature sensor 22, a first buzzer 23, a light alarm 24, a smoke sensor 25, a second buzzer 26 and a controller 27. The housing 21 is used to connect with the building wall. Four connecting plates 211 extend from one side of the housing 21 connected with the wall. These connecting plates 211 are all provided with through slots 212, and bolts 213 are inserted into the through slots 212. When in use, the bolts 213 are screwed into the embedded nuts in the wall to complete the threaded connection of the housing 21 with the building wall.

[0022] like Figure 3 As shown, the temperature sensor 22, the first buzzer 23, the light alarm 24, the smoke sensor 25, and the second buzzer 26 are all connected to the housing 21, and the temperature sensor 22, the first buzzer 23, the light alarm 24, the smoke sensor 25, and the second buzzer 26 are all fixedly arranged outside the housing 21; Figure 2 As shown, the controller 27 is arranged inside the housing 21. The signal input end of the controller 27 is signal-connected to the signal output end of the temperature sensor 22, and the signal input end of the controller 27 is also signal-connected to the signal input end of the smoke sensor 25; the signal output end of the controller 27 is signal-connected to the signal input end of the first buzzer 23, the signal input end of the light alarm 24, and the signal input end of the second buzzer 26.
