Description

Technical Field

[0001] The utility model relates to the technical field of underground pipe gallery fire monitoring, and more specifically to an online monitoring and early warning device for urban underground comprehensive pipe gallery fire. Background Art

[0002] As an important part of modern urban infrastructure, urban underground utility corridors are centrally arranged with various engineering pipelines such as electricity, communications, gas, heating, water supply and drainage, and are the key "lifeline" to ensure the normal operation of the city. With the rapid development of urban construction, the number and scale of underground utility corridors are constantly expanding, and the requirements for the safety and reliability of utility corridors are becoming higher and higher. Due to the presence of a large number of flammable and explosive substances in underground utility corridors, such as power cables and gas pipelines, once a fire occurs, the consequences will be disastrous. Fire will not only cause huge losses to the facilities in the utility corridor, but may also pose a serious threat to the surrounding environment and personnel safety.

[0003] Traditional fire monitoring methods, such as smoke alarms and temperature sensors, can prevent fires to a certain extent, but they have disadvantages such as limited monitoring range and slow response speed. For the special environment of underground utility corridors, traditional fire monitoring methods are often difficult to meet the needs.

[0004] With the continuous development of technologies such as the Internet of Things, big data, and cloud computing, intelligent monitoring technology has gradually become an important means in the field of fire prevention and monitoring. Intelligent monitoring technology has functions such as real-time monitoring, data analysis, and remote control, and can achieve all-round, efficient, and accurate fire monitoring and early warning for underground utility tunnels.

[0005] Therefore, how to overcome the defects of fixed monitoring range, slow response speed, and inability to accurately locate the fire source in the existing technology of pipeline corridor fire monitoring, and improve the fire prevention and monitoring level of underground comprehensive pipeline corridors, is an urgent problem that technical personnel in this field need to solve.

[0034] Furthermore, a second cross bar 7 is welded to the longitudinal bar 3, and the other end of the second cross bar 7 is connected to the driven wheel 8 through a rotating shaft. The second cross bar 7 and the driven wheel 8 are also provided in four groups, corresponding to the number of longitudinal bars 3. The driven wheel 8 is in contact with the lower surface of the track 1 to increase the stability of the mobile unit. The rotating shaft is movably connected to the driven wheel 8 and the second cross bar 7. In order to enable the mobile unit to move stably on the track 1, the upper surface and lower surface of the track 1, as well as the periphery of the driving wheel 6 and the driven wheel 8, are all set to a regular serrated structure embedded in each other.

[0035] The monitoring unit includes a shell 14 and an infrared temperature sensor 9 , a temperature sensor 10 , and a smoke sensor 11 mounted on the shell 14 . The shell 14 is welded to the lower end of the longitudinal rod 3 .

[0036] In the specific implementation process, one temperature sensor 10 and one smoke sensor 11 are provided and arranged directly below the housing 14, while two or four infrared temperature sensors 9 are preferably provided. When four infrared temperature sensors 9 are provided, two of the infrared temperature sensors 9 are oriented toward the pipeline directions on both sides, and the other two infrared temperature sensors 9 are oriented toward the front and rear directions of the pipe gallery. When two infrared temperature sensors 9 are provided, the two infrared temperature sensors 9 are oriented toward the front and rear directions of the pipe gallery.

[0043] When the device of the utility model is working, the infrared temperature sensor 9, temperature sensor 10, smoke sensor 11 and fiber-optic temperature detector in the monitoring unit begin to collect data such as the current position temperature, smoke and temperature in different directions in the tunnel, and transmit them to the control main board in real time for analysis and processing to determine the suspected direction of the fire source. The control main board controls the forward and reverse motor 5 to work, so that the mobile unit moves in the direction of higher temperature to further confirm whether a fire has occurred and determine the location of the fire source. Once the fire source is confirmed or the preset alarm threshold is reached, the control main board will start the alarm unit and send out an audible and visual alarm through the speaker 12 and the alarm light 13. At the same time, the GPS positioning device determines the location of the device, and transmits the location, temperature and other information to the remote terminal through the signal transmission unit to notify relevant staff to carry out fire prevention or rescue.
