Description

Technical Field

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

[0002] A fire refers to a disaster caused by combustion that gets out of control in terms of time or space. Among various disasters, fire is one of the most frequent and common disasters threatening public safety and social development. Nowadays, fires occur frequently. In order to strengthen fire prevention and control work, reduce the impact of disasters, and minimize the number of affected people, fire monitoring and alarm warning devices are often used for prediction and warning, enabling people to escape from the fire scene in time and reducing losses.

[0003] For example, a fire detection device for buildings that is convenient to disassemble disclosed in Chinese Patent CN202122055220.2. It can be seen that in this utility model, a sliding device and a clamping device are arranged on the whole device. A second groove is opened at the upper end of the stabilizing frame, and a bearing groove is opened on the lower frame wall of the stabilizing frame for placing the main body of the fire detection device. A skateboard with a T-shaped structure is slidably installed in two sliding grooves on the mounting plate, enhancing the sliding stability of the stabilizing frame. However, it does not solve the problem that most current early warning monitoring and alarms adopt methods such as setting up smoke benchmarks, but these methods cannot achieve timely monitoring and alarm. When the smoke volume exceeds the limit, an alarm cannot be given in time to complete the early warning work. Content of the Utility Model

Detailed implementation mode

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] A fire warning device, such as Figure 1-2 shown, includes a guide rod 2. The top and bottom ends of the guide rod 2 are respectively connected with support plates 6 by threads, and a fastening bolt 7 is connected to the outer wall of one side of the support plate 6 by threads. Guide rails 4 are respectively welded to the outer walls of both sides of the guide rod 2. A detection component is slidably connected to the guide rails 4. A contact terminal is arranged at the top of the detection component, and a connector 5 is connected to the top circumference of the guide rod 2 by threads. The connector 5 is adapted to the contact terminal. An alarm 8 is fixed to the top outer wall of the support plate 6 by bolts, and the alarm 8 is electrically connected to the connector 5;

[0023] The overall device is fixed to the designated measurement position of the operation through the support plate 6. When the contact terminal contacts the connector 5 at the top of the guide rod 2, the alarm 8 is triggered to open, and the alarm 8 makes a sound to start alarming, thus overcoming the problem of monitoring and alarming by the traditional method of using a benchmark and warning, promoting the safety of warning, and ensuring the timeliness of early warning.

[0024] Such as Figure 1-3 shown, the detection component includes a moving cylinder 1, a hemispherical cavity 3, a sliding disk 9, a chute 10, a guide ring 11, a turntable 12, an annular groove 13, a touch sensor 14 and a guide ball 15. The sliding disk 9 is slidably connected to the guide rails 4 through the chute 10. The guide ring 11 is arranged on the circumference of the sliding disk 9. The circumference of the guide ring 11 is rotatably connected to the turntable 12 through the annular groove 13. The moving cylinder 1 is fixed to the outer walls on both sides of the circumference of the turntable 12 by bolts. The hemispherical cavity 3 is connected to the end of the moving cylinder 1 by threads. The guide ball 15 is arranged in the hemispherical cavity 3. The touch sensor 14 is arranged on both inner sides of the hemispherical cavity 3. The annular groove 13 and the guide ring 11 form a sliding fit. The touch sensor 14 is connected to the flash lamp module in the alarm 8 through a signal line;

[0025] The turntable 12 on one side of the moving cylinder 1 rotates left and right under the push of the wave. When the moving cylinder 1 rotates around the turntable 12, the guide ball 15 in the hemispherical cavity 3 at its end shakes inside it and hits the touch sensor 14 in the hemispherical cavity 3. At this time, the touch sensor 14 will transmit the collision frequency information to the controller in the alarm 8 through the signal line. At this time, after the flash lamp module in the alarm 8 receives the information, its flashing frequency increases, and different early warning schemes are adopted, improving the practicability.

[0026] Working principle: The overall device is fixed at the designated early warning position of the operation through the support plate 6, and the moving cylinder 1 starts to move, completing left and right rotational swinging. When the moving cylinder 1 rotates around the turntable 12, the guide ball 15 inside its end hemispherical cavity 3 shakes inside it and impacts the touch sensor 14 inside the hemispherical cavity 3. At this time, the touch sensor 14 transmits the collision frequency information to the controller inside the alarm 8 through the signal line. At this time, after the flashing module inside the alarm 8 receives the information, its flashing frequency increases, and the personnel located in the distance can give an early warning according to the flashing frequency of the alarm 8.

[0027] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
