Description

Technical Field

[0001] This utility model relates to the field of fire protection technology, and in particular to a portable fire location detector. Background Technology

[0002] Among various disasters and accidents, fires occur frequently and cause great harm, seriously threatening people's lives and property and social stability. Fire rescue environments are complex, with high temperatures, dense smoke, and explosion risks coexisting. Building structures become less stable under the influence of fire and may collapse at any time, posing a significant threat to the lives of rescue personnel.

[0003] Currently, fire monitoring typically involves using fixed fire information detection devices (such as smoke detectors, heat detectors, and flame detectors) to monitor fire characteristic parameters in the environment in real time. When the detected data exceeds a preset threshold, the device automatically triggers an alarm signal, links the fire alarm controller, and activates equipment such as audible and visual alarms and emergency broadcasts. At the same time, it can transmit fire information to the fire control center or remote monitoring platform to achieve early warning and rapid response to fires, providing critical time for personnel evacuation and fire fighting and rescue.

[0004] However, the aforementioned fire information detection devices have low flexibility and cannot detect fire information in areas not covered by fixed sensors. For example, in mine fires, not only are there high temperatures and toxic and harmful gases, but the fire wind pressure may also cause airflow turbulence, expanding the scope of the fire's impact and increasing the difficulty of rescue. In building fires, problems such as the unknown location of trapped personnel and blocked fire lanes also seriously hinder rescue operations. Utility Model Content

Detailed Implementation

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0043] Although the present invention can be readily embodied in various forms, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0044] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0045] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0046] Currently, fixed fire information detection devices have two main problems when conducting comprehensive fire detection: First, the fixed installation location of fixed fire information detection devices results in a severe lack of flexibility. If the internal layout of the building changes or complex, concealed spaces appear, fixed fire information detection devices will struggle to cover the entire area, easily creating blind spots and delaying the collection of critical fire data, thus affecting the timing of emergency rescue. Second, the limited functionality of traditional detection equipment makes it difficult for fixed instruments to achieve multi-dimensional and systematic comprehensive monitoring when multiple fire characteristic parameters occur simultaneously.

[0047] Head-mounted fire detectors are portable devices that integrate functions such as camera, information sensing, and trajectory reconstruction. However, head-mounted fire detectors suffer from ergonomic design flaws (heavy weight, poor breathability), insufficient environmental adaptability (limited impact resistance), and high operation and maintenance costs.

[0048] This utility model provides a portable fire location detector that can solve some or all of the above-mentioned technical problems.

[0049] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , Figure 1 This is a schematic diagram of the structure of a portable fire location detector 10 provided in an embodiment of this utility model. Figure 2 yes Figure 1 The portable fire location detector 10 shown is a structural schematic diagram from another perspective. Figure 3 yes Figure 2 The diagram shown is a cross-sectional view of the portable fire location detector 10 along the A1-A2 position. Figure 4 yes Figure 1 The diagram shows an exploded structure of a portable fire locator 10. The portable fire locator 10 may include: a housing 11, a battery assembly 12, a control assembly 13, a satellite locator (not shown in the figure), and a sensor assembly 14.

[0050] The device housing 11 has a receiving chamber and a first opening k1 and a second opening k2 disposed opposite to each other. Both the first opening k1 and the second opening k2 communicate with the receiving chamber, and a flue gas flow channel is formed between the first opening k1 and the second opening k2. It is understood that this flue gas flow channel can be a portion of the space within the receiving chamber located between the first opening k1 and the second opening k2. Flue gas from the environment can enter the receiving chamber through the first opening k1, flow through the flue gas flow channel, and then exit the receiving chamber through the second opening k2. The material of the device housing 11 can include metal or plastic.

[0051] Battery assembly 12, control assembly 13, satellite locator, and sensor assembly 14 are all installed in the housing chamber and are electrically connected to control assembly 13. The satellite locator is a smart terminal device that achieves real-time location tracking by receiving signals from a global navigation satellite system. For example, the satellite locator may include the Global Positioning System (GPS) and the BeiDou Navigation Satellite System (BDS), such as a NEO-M8N module. The satellite locator can transmit the detected location information to control assembly 13 in real time. Sensor assembly 14 can be used to detect fire characteristic parameters in the environment in real time and send the detected data to control assembly 13. Control assembly 13 can analyze the detection data acquired by the sensors. When the detection data exceeds a preset threshold, control assembly 13 can transmit fire information and current location information to the fire control center or remote monitoring platform.

[0052] The battery assembly 12, control assembly 13, and sensor assembly 14 are stacked sequentially along the direction closest to the smoke flow duct. That is, the battery assembly 12 and sensor assembly 14 can be located on opposite sides of the control assembly 13, with the sensor assembly 14 positioned on the side of the control assembly 13 closest to the smoke flow duct. This allows the sensor assembly 14 to be closer to the smoke flow duct, enabling faster and more accurate detection of fire characteristic parameters in the environment. Furthermore, this design allows for a more compact internal structure of the portable fire location detector 10, reducing its overall size.

[0053] The portable fire location detector 10 in this embodiment of the invention can be made of lightweight materials and has a compact internal structure and small overall size, making it easy for rescue personnel to carry and having minimal impact on their movements, thus enhancing its flexibility. Furthermore, the portable fire location detector 10 can simultaneously acquire location information and fire detection information, and promptly feed the acquired information back to the fire control center or remote monitoring platform, providing comprehensive and reliable detection information for fire rescue operations, thereby improving the reliability and rescue efficiency of the portable fire location detector 10.

[0054] In summary, this utility model embodiment provides a portable fire location detector 10 comprising a housing 11, a battery assembly 12, a control assembly 13, a satellite locator, and a sensor assembly 14. The housing 11 has a first opening k1 and a second opening k2 arranged opposite to each other, and a smoke flow channel located between the first opening k1 and the second opening. The battery assembly 12, the satellite locator, and the sensor assembly 14 are all electrically connected to the control assembly 13, and the battery assembly 12, the control assembly 13, and the sensor assembly 14 are stacked sequentially along the direction close to the smoke flow channel. The portable fire location detector 10 can simultaneously acquire location information and fire detection information, and promptly feed the acquired information back to the fire control center or remote monitoring platform, improving the reliability and rescue efficiency of the portable fire location detector 10. Furthermore, the portable fire location detector 10 in this utility model embodiment has a compact internal structure and a small overall size, making it easy for rescue personnel to carry and having minimal impact on their movements, thus making the portable fire location detector 10 highly flexible.

[0055] Furthermore, since the sensor assembly 14 is located on the side of the control assembly 13 closer to the smoke flow channel, the sensor assembly 14 can be closer to the smoke flow channel, thereby enabling faster and more accurate detection of fire characteristic parameters in the environment.

[0056] Please refer to Figure 3 and Figure 5 , Figure 5 This is a schematic diagram of the structure of a sensor assembly 14 provided in an embodiment of the present invention. In an optional embodiment, the sensor assembly 14 may include a sensor circuit board 141 and a smoke sensor 142, a humidity sensor 143 and a temperature sensor 144 mounted on the sensor circuit board 141.

[0057] The sensor circuit board 141 is fixedly connected to the control component 13; the smoke sensor 142, humidity sensor 143 and temperature sensor 144 are installed on the side of the sensor circuit board 141 near the flue gas flow channel, and at least a portion of the smoke sensor 142, at least a portion of the humidity sensor 143 and at least a portion of the temperature sensor 144 are located in the flue gas flow channel.

[0058] The smoke sensor 142 detects the concentration of airborne particles using photoelectric or ionization principles for fire early warning, sending a signal to the control component 13 when the smoke concentration exceeds a threshold. The humidity sensor 143 measures the ambient moisture content based on changes in capacitance or resistance. The temperature sensor 144 can monitor changes in ambient heat using thermocouples, thermistors, or infrared technology. The smoke sensor 142, humidity sensor 143, and temperature sensor 144 can be integrated via a sensor circuit board 141 and electrically connected to the control component 13 to construct a multi-dimensional environmental monitoring element. The sensor component 14 can transmit data via an I2C interface and an ADC interface.

The display component 15 may be mounted on the device housing 11 and is electrically connected to the control component 13. Thus, the control component 13 can transmit fire information and current location information to the display component 15 for display, enabling rescue personnel to promptly understand their safety situation and make safe and efficient decisions. For example, the display component 15 may include a 4.3-inch touchscreen.

[0060] In an optional embodiment, the portable fire location detector 10 may further include an inertial navigator (not shown); the inertial navigator is located outside the device housing 11 and is wirelessly connected to the control component 13. The inertial navigator is an autonomous navigation device that does not rely on external signals. By measuring the acceleration and angular velocity of the carrier's motion, it calculates the position, attitude, and velocity information in real time through integration. The inertial navigator can be fixed to the ankle of the rescuer. Thus, by fusing the positioning information from the satellite locator and the inertial navigator, the firefighter's movement trajectory can be recorded in real time, facilitating accurate location of rescuers in complex fire scenes.
