Description

Technical Field

[0001] The present application relates to the field of firefighting and rescue helmets, and in particular to an infrared thermal imaging firefighting and rescue intelligent helmet device. Background Art

[0002] The Fire and Rescue Smart Helmet is a helmet equipped with advanced technology, designed to improve the safety and work efficiency of firefighters and rescue workers in emergency situations. It combines multiple intelligent functions. Infrared thermal imaging is a technology that uses infrared technology to detect thermal radiation emitted by objects and generate images. By observing the thermal imaging camera, it can help identify the source of fire, temperature changes and the location of trapped people in low-visibility environments (such as thick smoke or darkness).

[0003] When the existing fire rescue smart helmets are equipped with infrared thermal imagers, due to the heavy smoke in the fire environment, the firefighters' internal vision clarity is poor. Although the infrared thermal imager can detect trapped people, it is inconvenient for firefighters to observe the distance between themselves and the trapped people, which may have a certain impact on the firefighters' judgment of the rescue plan and the rescue time, which in turn affects the safety of firefighters when rescuing trapped people and reduces the overall use efficiency of the fire rescue smart helmets.

[0004] In response to the above-mentioned related technologies, the inventor believes that the fire rescue smart helmet equipped with an infrared thermal imager has the defect of being inconvenient to observe the distance between the firefighters and the trapped people. Therefore, an infrared thermal imaging fire rescue smart helmet device is proposed to solve the above problem. Utility Model Content

[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses an infrared thermal imaging fire rescue smart helmet device. Figure 1-4 , an infrared thermal imaging fire rescue smart helmet device, including an AR protective lens 2 rotatably installed in the middle of the front end of the smart fire helmet 1, a mounting bracket 3 is installed on the upper surface of the smart fire helmet 1 near the front, and an infrared thermal imager 4 is installed on one end of the mounting bracket 3 through a damping bearing, a fixed bracket 5 is fixedly installed on one side of the outer surface of the smart fire helmet 1, and a limit card 6 is symmetrically and movably installed on one end of the fixed bracket 5, and a laser rangefinder 10 is installed between the two limit cards 6. An arc groove is opened on one side edge of the limit card 6, and both sides of the laser rangefinder 10 are located inside the arc groove. The limit card 6 and the laser rangefinder 10 are embedded with each other, and a laser emitter 11 is provided on the edge of one end of the laser rangefinder 10, and the middle of the other end of the laser rangefinder 10 extends to the top of the inner wall of the smart fire helmet 1 and is fixedly connected with a connecting line 12, and the edge of one end of the connecting line 12 is placed inside the smart fire helmet 1 and a data processing module 13 is installed. The smart fire helmet 1 is also provided with a display mechanism inside for displaying the detection distance of the laser rangefinder 10.

[0021] By installing the laser rangefinder 10 on the smart fire helmet 1, connecting one end of the laser rangefinder 10 to the connecting line 12, and using the laser emitter 11 to cooperate with the infrared thermal imager 4 to measure the distance, the measured distance is transmitted to the data processing module 13 through the connecting line 12 for processing, and the distance is digitally displayed on the transparent display screen 15, which demonstrates the effect of the laser rangefinder 10 in measuring the distance between firefighters and trapped people.

[0022] Reference Figure 4 The display mechanism includes a support frame 14, which is symmetrically rotatably installed on the inner wall of the smart fire helmet 1 near the middle of the front end surface through a damping bearing. A transparent display screen 15 is installed between the two support frames 14. One end of the transparent display screen 15 is electrically connected to the data processing module 13. A groove is opened in the middle of one side of the support frame 14, and both side edges of the transparent display screen 15 are located in the groove, and the transparent display screen 15 and the groove are engaged with each other.

[0023] When in use, the transparent display screen 15 is taken out of the smart fire helmet 1 by rotating the support frame 14, so that the transparent display screen 15 is placed in front of the person's face. By displaying the measured distance on the transparent display screen 15, the firefighters can observe the transparent display screen 15 in the fire scene to judge the distance between themselves and the trapped persons, which reflects the display effect of the transparent display screen 15 on distance.

[0024] Reference Figure 1 and Figure 3 A fixing groove 7 is symmetrically opened on the edge of one end of the fixing bracket 5, and tension springs 8 are installed on both sides of the inner wall of the fixing groove 7. One end of the limit clamp 6 extends to the inside of the fixing groove 7 and is welded with a fixing protrusion 9. One side of the tension spring 8 abuts against the outer surface of the fixing protrusion 9.

[0025] By pulling the two limit clips 6 apart from each other, the fixed protrusion 9 moves along the inside of the fixing groove 7 to drive the tension spring 8 to compress, and the laser rangefinder 10 is placed on the outer surface of the smart fire helmet 1 between the two limit clips 6, so that the tension spring 8 drives the limit clips 6 to approach each other, and then the two limit clips 6 clamp and fix the laser rangefinder 10, reflecting the installation and fixing effect of the laser rangefinder 10 between the two limit clips 6.

[0026] The implementation principle of the infrared thermal imaging fire rescue smart helmet device of the present application embodiment is as follows: by pulling the two limit clamps 6 apart from each other, the fixed protrusion 9 moves along the inside of the fixed groove 7 to drive the tension spring 8 to compress, and the laser rangefinder 10 is placed on the outer surface of the smart fire helmet 1 between the two limit clamps 6, so that the tension spring 8 drives the limit clamps 6 to move closer to each other, and then the two limit clamps 6 clamp and fix the laser rangefinder 10, so that one end of the laser rangefinder 10 is connected to the connecting line 12, the infrared thermal imager 4 is rotated to be placed at the operator's eyes for observation, and the support frame 14 is rotated to place the transparent display screen 15 in front of the human face, so that the laser emitter 11 is equipped with a laser rangefinder. The infrared thermal imager 4 is combined with the laser rangefinder 10 to measure the distance, and the measured distance is transmitted to the data processing module 13 through the connecting line 12 for processing, and the distance is digitally displayed on the transparent display screen 15, so that people can observe the transparent display screen 15 to judge the distance to the trapped person. The input ends of the power supply of the infrared thermal imager 4, the laser rangefinder 10, the data processing module 13 and the transparent display screen 15 are all electrically connected to the output end of the external power supply. Compared with the existing technology, this solution has the effect of facilitating the observation of the distance between the trapped person and the firefighter, improving the overall use efficiency of the smart fire helmet 1, and solving the problem that the fire scene environment is smoky and it is inconvenient for firefighters to observe the position of the trapped person.
