Description

Technical Field

[0001] This invention relates to a detection device for a fire scene, and more particularly to a device for detecting underground fires. Background Technology

[0002] When an underground fire occurs, there is currently no specialized equipment for detecting underground fires. The detection of underground fires mainly relies on the experience of rescuers or professionals to determine whether a fire has occurred underground. This method is very inaccurate. Due to inaccurate measurements, underground fires and explosions may occur without prior knowledge, causing not only personal injury and property damage, but also unpredictable damage to underground public spaces. Summary of the Invention

[0003] This invention provides a device for detecting underground fires. It can accurately measure underground fires and has a simple structure and is easy to operate, thus ensuring the safety of underground facilities.

[0004] This invention employs the following technical solution: a device for underground fire detection, comprising an operating rod and a detection head. An operating handle is mounted on the upper end of the operating rod, and the lower end of the operating rod is rotatably connected to the detection head. The operating rod is placed at an angle. The detection head includes a horizontally arranged heat-insulating measuring disk, within which an infrared temperature detection sensor and a hazardous gas detection sensor are installed. The temperature signal receiving end of the infrared temperature detection sensor is close to the ground of the measured area. The signal from the infrared temperature detection sensor is used to collect and detect the temperature signal of the underground environment to determine whether an underground fire has occurred. The hazardous gas detection sensor is used to detect gases released from the underground environment to determine whether harmful gases are being released due to combustion. The gas signal receiving end of the hazardous gas detection sensor is close to the ground of the measured area. The signal output terminals of the infrared temperature detection sensor and the hazardous gas detection sensor in the measurement area are connected to the signal input port of the microcontroller. The signal input port of the microcontroller is connected to the input terminal of the display on the upper part of the operating lever. When measurement is required, the position of the heat insulation measuring plate is flipped and adjusted so that the heat insulation measuring plate is close to the ground of the measurement area. The infrared temperature detection sensor and the hazardous gas detection sensor are also close to the ground of the measurement area. At this time, if the ground temperature is too high, there will also be harmful gases emitted after combustion. The infrared temperature detection sensor and the hazardous gas detection sensor respectively send the temperature signal and the hazardous gas signal to the microcontroller for signal processing. Then, the processed signals are sent to the display for display of the temperature signal and the hazardous gas signal, thereby determining whether there is a fire underground and the fire situation.

[0005] Furthermore, a power supply is installed in the middle of the operating lever of the present invention, and the power supply terminals of the infrared temperature detection sensor and the hazardous gas detection sensor, the power supply terminal of the microcontroller and the power supply terminal of the display are all connected to the power supply.

[0006] Furthermore, the power source for this invention is a rechargeable lithium battery.

[0007] Furthermore, the lower end of the operating lever of the present invention is rotatably connected to the side of the heat insulation measuring plate via a hinge. The heat insulation measuring plate is configured as a circular plate with an open top. The heat insulation measuring plate is made of carbon fiber. The infrared temperature detection sensor and the hazardous gas detection sensor are placed inside the heat insulation measuring plate. A removable carbon fiber protective cover is installed at the opening at the top of the heat insulation measuring plate.

[0008] Furthermore, the display of the present invention is connected to the operating lever via a mounting bracket. The mounting bracket is configured as an L-shaped support frame, which is vertically mounted on the operating lever. The display is mounted on the side of the L-shaped support frame and points towards the operating handle.

[0009] Furthermore, the operating handle of the present invention is configured as a rod, with one end of the operating handle bent upward to form an arc transition with the upper end of the operating rod. This arc transition is the grip area during operation. The other end of the operating handle is vertically mounted with an arm bracket, which is configured as a semi-circular frame with an upward opening.

[0010] Furthermore, the hazardous gas detection sensor of the present invention includes a carbon monoxide detection sensor and a sulfur dioxide detection sensor.

[0011] Furthermore, the operating lever of the present invention is a telescopic operating lever.

[0012] This invention offers the following advantages: By employing the above technical solution, this invention can utilize infrared temperature detection sensors and hazardous gas detection sensors to measure temperature and detect hazardous gases in areas suspected of having underground fires. Not only are the measurements accurate, allowing for the determination of whether an underground fire has occurred based on the measured temperature and gas levels, but the invention also features a simple structure and convenient operation, requiring no complex procedures. Professional personnel can use this assessment to provide early warnings and take preventative and control measures, thereby ensuring the safety of underground public facilities. This invention uses a combination of infrared temperature detection sensors and hazardous gas detection sensors for measurement, further improving measurement accuracy and providing double protection. While excessively high temperatures do not necessarily indicate a fire, the presence of excessively high temperatures and the emission of harmful gases such as carbon monoxide and sulfur dioxide greatly increases the likelihood of a fire. The lower end of the operating lever of this invention is rotatably connected to the side of the heat-insulating measuring plate via a hinge. This allows for convenient and accurate adjustment of the heat-insulating measuring plate's position, ensuring it is in the optimal measuring location. Furthermore, the heat-insulating measuring plate is made of carbon fiber, and the infrared temperature detection sensor and hazardous gas detection sensor are housed within it. A removable carbon fiber protective cover is installed at the opening at the top of the heat-insulating measuring plate. This provides protection against damage to the two detection sensors even at high temperatures, thanks to the carbon fiber plate and protective cover. The display of this invention is connected to the operating lever via a mounting bracket. The mounting bracket is an L-shaped support, vertically mounted on the operating lever. The display is mounted on the side of the L-shaped support, pointing towards the operating lever. This not only ensures a secure installation of the display but also facilitates observation of the screen by the testing personnel. The operating handle of this invention is bent upwards at one end to form an arc transition with the upper end of the operating rod. This arc transition is the grip area during operation. The other end of the operating handle is vertically mounted with an arm support. The arm support is set as a semi-circular frame with the opening facing upwards. This not only allows the measuring personnel to perform measurements in a better posture, but also improves the comfort of the testing personnel during use. Attached Figure Description

[0017] exist Figure 1 and Figure 2 This invention provides a device for detecting underground fires, comprising an operating lever 1 and a detection head 2. An operating handle 3 is mounted on the upper end of the operating lever 1, and the lower end of the operating lever 1 is rotatably connected to the detection head 2. The operating lever 1 is placed at an angle. The detection head 2 includes a horizontally arranged heat-insulating measuring disk 4, within which an infrared temperature detection sensor 5 and a hazardous gas detection sensor are installed. The temperature signal receiving end of the infrared temperature detection sensor 5 is close to the ground of the measured area. The signal from the infrared temperature detection sensor 5 is used to collect and detect the temperature signal of the underground environment to determine the underground fire source. To determine whether a fire has occurred underground, the hazardous gas detection sensor 6 is used to detect gases released from the underground environment, thereby determining whether harmful gases are being released due to combustion. The gas signal receiving end of the hazardous gas detection sensor 6 is close to the ground of the measured area. The signal output ends of both the infrared temperature detection sensor 5 and the hazardous gas detection sensor 6 are connected to the signal input port of the microcontroller 7. The signal input port of the microcontroller 7 is connected to the input end of the display 8 located on the upper part of the operating lever. In this embodiment, a power supply 9 is installed in the middle of the operating lever 1. The optimized solution is that the power supply 9 is a rechargeable lithium battery. The power terminals of the detection sensor 5 and the hazardous gas detection sensor 6, the power terminal of the microcontroller 7, and the power terminal of the display 8 are all connected to the power supply 9. In this embodiment, the lower end of the operating lever is rotatably connected to the side of the heat-insulating measuring disk 4 via a hinge. The heat-insulating measuring disk 4 is a circular disk with an open top and is made of carbon fiber. The infrared temperature detection sensor 5 and the hazardous gas detection sensor 6 are placed inside the heat-insulating measuring disk 4. A removable carbon fiber protective cover 13 is installed at the opening at the top of the heat-insulating measuring disk 4. In this embodiment, the display 8 is connected to the operating lever 1 via a mounting bracket 10. The operating lever 1 is mounted on an L-shaped support frame, which is vertically mounted on the operating lever 1. The display 8 is mounted on the side of the L-shaped support frame and points towards the operating handle 3. In this embodiment, the operating handle 3 is rod-shaped. One end of the operating handle 3 is bent upward to form an arc transition 11 with the upper end of the operating lever 1. This arc transition 11 is the grip area during operation. The other end of the operating handle 3 is vertically mounted with an arm bracket 12. The arm bracket 12 is a semi-circular frame with an upward opening. In this embodiment, the hazardous gas detection sensor 6 includes a carbon monoxide detection sensor and a sulfur dioxide detection sensor. In this embodiment, the operating lever 1 is a telescopic operating lever.

[0018] The process of using this invention is as follows: When the surface temperature is too high, it is necessary to measure the area with excessively high temperature using this invention. When measurement is required, firstly, the position of the heat insulation measuring plate 4 is flipped and adjusted so that the heat insulation measuring plate 4 is close to the ground of the area to be measured, so that the infrared temperature detection sensor 5 and the hazardous gas detection sensor 6 inside the heat insulation measuring plate 4 are also close to the ground of the area to be measured for measurement. After the infrared temperature detection sensor 5 and the hazardous gas detection sensor 6 detect the area with excessively high temperature, they send the detected temperature signal and hazardous gas signal to the microcontroller 7 for signal processing, and then send the processed signal to the display 8 to display the temperature signal and hazardous gas signal. At this time, when the underground temperature displayed on the display 8 reaches 100℃-150℃, and carbon monoxide and sulfur dioxide are emitted, it can be indicated that an underground fire has occurred in the area, reminding professionals to take measures to control and extinguish the underground fire.

[0019] Not limited to this, any variations or substitutions conceived without inventive effort should be included within the scope of protection of this invention. Therefore, the scope of protection of this invention should be determined by the scope defined in the claims.
