Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to an alarm device for fire fighting detection. Background Art

[0002] Firefighting is to eliminate hidden dangers and prevent disasters. It is a general term for preventing and solving man-made, natural and accidental disasters encountered by people in the process of life, work and study. Of course, the meaning of firefighting in people's early understanding is: fire, mainly including the rescue of personnel at the fire scene, the rescue of important facilities and equipment, cultural relics, the safety protection and rescue of important property, and extinguishing fires.

[0003] Among the equipment used for fire detection, smoke alarms are mostly used for detection, and fire extinguishing operations are carried out through temperature-sensing sprinklers. However, in some places with high floor heights, hidden fires, that is, the early stages of flames, will only produce more smoke and cannot increase the top temperature, which can easily cause the spraying equipment to fail to start. At the same time, due to the high floor heights and inconvenient maintenance, dust can easily cause false alarms or insufficient sensitivity of the smoke alarm. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an alarm device for fire detection suitable for the top of a high building in view of the deficiencies raised in the above-mentioned background technology.

[0006] Furthermore, the top and bottom of the control box are respectively connected with an upper fixed connecting plate and a lower fixed connecting plate, which facilitates the fixed connection setting of the control box and the detection box.

[0007] Furthermore, a hot air channel is provided in the heater, and a hot air fan and an electric heating network are connected in the hot air channel to facilitate the hot air blowing operation.

[0008] Furthermore, the control box is connected with a backup battery and a single-chip microcomputer controller to facilitate power supply and control of electrical components in the device.

[0009] Furthermore, a buzzer and an alarm light are connected to the outside of the detection box to facilitate auxiliary alarm operations.

[0010] The advantages of the fire detection alarm device of the utility model compared with the prior art are: the utility model can perform pre-detection and accurate detection through dual smoke alarms, thereby ensuring the accuracy of the smoke alarm, and at the same time, by blowing out hot air to heat the sprinkler head, some hidden fires can be quickly extinguished.

[0014] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0015] Combined with Figure 1-2 A fire detection alarm device comprises a control box 1, a detection box 2 and a high-pressure water pipe 5. The control box 1 is connected with a backup battery 20 and a single-chip controller 21. The detection box 2 is connected with a buzzer 22 and an alarm light 23 on the outside. The top and bottom of the control box 1 are respectively connected with an upper fixed connecting plate 3 and a lower fixed connecting plate 4. The control box 1 can be connected to the top plate or the connecting piece by bolts, which facilitates the connection operation between the control box 1 and the detection box 2. The bottom of the detection box 2 is connected with a first smoke alarm 6, which is exposed for daily pre-detection.

[0016] A precise detection channel 7 is provided in the middle of the detection box 2, and an air inlet 8 and an air outlet 9 are respectively provided at both ends of the precise detection channel 7. The air inlet 8 and the air outlet 9 are both connected with an electrically controlled valve 10 electrically connected to the first smoke alarm 6. A second smoke alarm 11 and an exhaust fan 12 are connected in the precise detection channel 7. The second smoke alarm 11 and the exhaust fan 12 are arranged in series with the electrically controlled valve 10. When the first smoke alarm 6 pre-detects an abnormality, in order to ensure precise detection, precise detection operations can be performed by starting the electrically controlled valve 10, the exhaust fan 12 and the second smoke alarm 11.

[0017] The high-pressure water pipe 5 extends to the bottom of the detection box 2 and is connected with a spray head 13. The bottom of the spray head 13 includes a heat-sensitive glass ball 14 and a spray plate 15. The bottom of the detection box 2 is connected with a heater 16 aimed at the heat-sensitive glass ball 14. When the second smoke alarm 11 detects, the heater 16 is started to heat and break the heat-sensitive glass ball 14, so that the water in the high-pressure water pipe 5 is sprayed out. The heater 16 is provided with a hot air channel 17. The hot air channel 17 is connected with a hot fan 18 and an electric heating network 19. The heater 16 starts the hot fan 18 and the electric heating network 19 to quickly blow out high-temperature gas.
