Description

Technical Field

[0001] The utility model belongs to the technical field of fire engineering equipment, and in particular relates to a wireless fire alarm device for fire engineering. Background Art

[0002] Among various disasters, fire is one of the most frequent and common major disasters that threaten public safety and social development. It is crucial to detect fires in a timely manner and take effective measures to extinguish the initial fires and minimize the loss of life and property caused by fires. Fire alarms play an important role in fire prevention. When a fire occurs, they can promptly alert people around.

[0003] However, the fire alarms currently on the market have the following drawbacks in actual use:

[0004] 1. Existing fire alarm devices are mostly fixed to the walls of buildings by bolts or adhesives. When the alarm needs maintenance or replacement due to aging, failure, fire damage, etc. during use, the installation and disassembly process of the alarm is more troublesome, which often increases the installation and maintenance costs. In addition, multiple disassembly and assembly will damage the wall and affect the appearance.

[0005] 2. When a fire hazard is detected, an alarm will sound to alert people around. However, because people are in a panic, they will be looking for escape routes while calling the police. They may be unfamiliar with the terrain and delay reporting the specific location of the fire, which will delay the best rescue time. In addition, the fire data cannot be monitored in real time, and firefighters cannot understand the disaster situation in time to carry out rescue.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0030] like Figure 1-7 As shown, a wireless fire alarm device for fire protection engineering includes an alarm body 1 and a mounting base 4. The alarm body 1 is detachably connected to the mounting base 4, and the alarm body 1 is fixed to the wall through the mounting base 4. The alarm body 1 includes an alarm housing 2. A connecting rod 3 is provided on the top of the alarm housing 2. The alarm body 1 and the mounting base 4 are connected by the connecting rod 3. The number of connecting rods 3 is the same as the number of mounting bases 4. The specific number can be selected according to actual use, and can be one, two or more. A control module is provided in the alarm housing 2. The control module is electrically connected to a monitoring module, an alarm module, a communication module and a power supply module. In this embodiment, the control module, the monitoring module, the alarm module, the communication module and the power supply module are all prior art.

[0031] Specifically, the monitoring module includes a smoke sensor and a temperature sensor. When the detection values ​​of the smoke sensor and the temperature sensor are abnormal at the same time, it is determined that a fire has occurred. By setting two monitoring indicators, it is possible to avoid incorrect detection results due to excessive cooking smoke or dust, which would cause unnecessary waste of resources for the fire brigade. The alarm module includes a buzzer and a warning light. The smoke sensor, temperature sensor, buzzer and warning light are all connected to the power supply module.

[0032] The alarm devices are installed at intervals on the walls of rooms, corridors or shopping malls. Each alarm device has a fixed number. The monitoring module monitors in real time whether a fire has occurred. When the detection data of the smoke sensor and the temperature sensor exceed the preset values ​​at the same time, it is determined that a fire has occurred. The communication module then sends the alarm message to the property manager and the fire rescue bureau in real time in the form of text messages, mini-programs or phone calls, specifically including the location of the fire and the current values ​​detected by the smoke sensor and temperature sensor, so that firefighters can understand the disaster in time and then carry out rescue in time, minimizing the rescue time wasted due to calling the alarm and describing the location of the fire. While sending the alarm message, an alarm signal is sent through a buzzer and warning light to remind people to evacuate in time.

[0033] Furthermore, the control module is electrically connected to an indicator light board 20 and an emergency lighting lamp 21, and a safety passage direction mark is provided on the indicator light board 20. The indicator light board 20 is always on, and when a fire occurs, the brightness of the indicator light board 20 increases, and the emergency lighting lamp 21 is turned on at the same time.

[0034] The mounting base 4 includes a mounting shell 5 and a clamping mechanism. The top of the mounting shell 5 is connected to the wall. A chamber is formed in the mounting shell 5. A first opening is provided at the bottom of the mounting shell 5. The upper part of the clamping mechanism is located in the chamber. The clamping mechanism is detachably connected to the connecting rod 3.

[0035] Specifically, the clamping mechanism includes a fixed cylinder 6, the top of the fixed cylinder 6 is fixedly connected to the inner top wall of the mounting shell 5, the middle of the fixed cylinder 6 is fixedly connected to the first opening of the mounting shell 5, the bottom wall of the fixed cylinder 6 is provided with a second opening, and a clamping member 7 and an adjusting member 8 are provided in the fixed cylinder 6, and the lower part of the adjusting member 8 extends downward through the second opening.

[0036] The clamping member 7 includes an integrally formed connecting portion 9 and a reducing portion 10, the top of the connecting portion 9 is fixedly connected to the inner top wall of the fixed cylinder 6, the connecting portion 9 is used to connect the fixed cylinder 6, and the reducing portion 10 is used to clamp the connecting rod 3. The bottom of the reducing portion 10 is rotatably connected with the adjusting member 8, the upper portion of the adjusting member 8 is provided with a threaded portion 11, the threaded portion 11 is threadedly connected with the fixed cylinder 6 at the second opening, and the adjusting member 8 extends downward through the second opening and is provided with a screwing portion 12. By rotating the screwing portion 12, the threaded portion 11 and the bottom wall of the fixed cylinder 6 are relatively rotated, thereby changing the height of the adjusting member 8 and changing the relative position of the adjusting member 8 and the clamping member 7.

[0037] A first clamping cavity 13 and a second clamping cavity 14 are respectively provided at the center of the clamping member 7 and the adjusting member 8. The connecting rod 3 is vertically located in the first clamping cavity 13 and the second clamping cavity 14. A plurality of third openings 15 are provided on the circumferential surface of the reducing portion 10. The third openings 15 penetrate the side wall of the reducing portion 10 and are connected to the first clamping cavity 13. The plurality of third openings 15 divide the reducing portion 10 into a plurality of clamping arms 16. By bringing adjacent clamping arms 16 closer to or farther away from each other, the diameter of the first clamping cavity 13 is changed, thereby clamping or loosening the connecting rod 3. A first inclined surface 17 is provided on the bottom outer wall of the reducing portion 10, and a second inclined surface 18 is provided on the top inner wall of the adjusting member 8. The first inclined surface 17 and the second inclined surface 18 are slidably matched. When the adjusting member 8 moves upward, the second inclined surface 18 slides relative to the first inclined surface 17. Since the diameter of the second clamping cavity 14 is fixed, when the second inclined surface 18 moves upward, the clamping arms 16 are brought closer to each other, thereby reducing the diameter of the first clamping cavity 13.

[0038] Specifically, an annular groove 19 is provided on the inner wall of the lower portion of the fixing cylinder 6 , and the annular groove 19 cooperates with the threaded portion 11 , so that there is movement space when the threaded portion 11 moves upward.

[0039] Specifically, through holes are provided at the four corners of the top of the mounting shell 5, and fixing bolts 22 are passed through the through holes. The mounting base 4 is fixed to the wall by the fixing bolts 22. When the alarm body 1 needs to be removed, there is no need to remove the fixing bolts 22. Disassembly and assembly can be achieved by adjusting the clamping mechanism, which is convenient to use.

[0040] When the alarm body 1 and the mounting base 4 are connected, the connecting rod 3 is passed through the second clamping cavity 14 and the first clamping cavity 13 from bottom to top in sequence, and then the screwing part 12 is rotated to make the threaded part 11 and the fixed cylinder 6 rotate relative to each other, the adjusting member 8 moves upward, and the second inclined surface 18 squeezes the first inclined surface 17 to reduce the size of each third opening 15, and the adjacent clamping arms 16 approach each other, and the diameter of the first clamping cavity 13 is reduced, thereby clamping the connecting rod 3.

[0041] When the alarm body 1 and the mounting base 4 are separated, the screwing part 12 is rotated in the opposite direction to move the adjusting member 8 downward, the second inclined surface 18 and the first inclined surface 17 slide relative to each other, and the clamping member 7 and the adjusting member 8 move away from each other. At this time, each third opening 15 gradually increases in size, and the diameter of the first clamping cavity 13 increases, thereby loosening the connecting rod 3, and then the alarm body 1 can be removed from the mounting base 4.

[0042] The working principle of the utility model is: when the detection data of the smoke sensor and the temperature sensor exceed the preset values ​​at the same time, it is determined that a fire has occurred, and then the communication module sends the specific location of the fire to the property manager and the fire rescue bureau in real time in the form of text messages, small programs or telephone calls, and sends an alarm signal through a buzzer and a warning light. At the same time, the brightness of the indicator light 20 increases, and the emergency lighting 21 is turned on to remind people to evacuate in time. After the fire, it is necessary to check whether the alarm device is damaged in time to avoid affecting normal use. In addition, the alarm device also needs to be jacked up for inspection and maintenance on a daily basis to prevent failure to alarm when a fire occurs. When disassembling the alarm body 1, its connecting rod 3 can be separated by simply adjusting the clamping mechanism.

[0043] The wireless fire alarm device for fire protection engineering provided by the utility model can quickly disassemble and assemble the alarm body 1 by providing a detachable mounting base 4 and an alarm body 1, while avoiding multiple disassembly and assembly to damage the wall and affect the appearance. The clamping mechanism is provided to facilitate the disassembly and assembly process. The connecting rod 3 can be clamped or loosened by simply rotating the screw part 12, thereby reducing the manpower and time costs of the replacement or maintenance process. The monitoring module monitors in real time whether a fire has occurred, and the communication module sends the alarm message in real time to the property manager and the fire rescue bureau in the form of text messages, mini-programs or calls, so that the fire location and fire data can be grasped in time to avoid delaying the best rescue time.

[0044] The specific implementation methods of the utility model described above do not constitute a limitation on the protection scope of the utility model. Any other corresponding changes and modifications made according to the technical concept of the utility model should be included in the protection scope of the claims of the utility model.
