Description

Technical Field

[0001] The utility model relates to the technical field of life rescue, in particular to a micro-vibration vital sign detection device. Background Art

[0002] The micro-vibration vital signs detection device is an advanced rescue equipment designed for finding trapped survivors in emergency situations such as natural disasters. This device uses special microelectronic processor technology to detect and identify tiny vibrations propagating in the air or solid media. These vibrations may come from the life activities of the trapped person, such as breathing, heartbeat, movement, or conscious distress signals, such as shouting, slapping, scratching or knocking. At disaster sites such as earthquakes and building collapses, there are often large amounts of rubble and concrete blocks. Traditional search and rescue methods are difficult to quickly locate survivors. The micro-vibration vital signs detection device can penetrate these obstacles and capture those weak signs of life that may be masked by other noises. Through efficient algorithms, the accuracy of detection is improved. This detection device plays a vital role in disaster relief. It not only improves rescue efficiency, but also significantly shortens rescue time and increases the chances of survival of the trapped. In rescue operations where every second counts, the micro-vibration vital signs detection device is an important tool for rescuers. It brings hope to life through the power of science and technology, and is a reflection of the continuous progress of modern rescue technology.

[0003] According to the search of China Utility Model Publication No.: CN207336770U, a miniature audio life detection device for earthquake disasters is disclosed. When searching for buried survivors or victims on site in disasters such as earthquakes, explosions, landslides, mine disasters or building collapses, the device of the utility model can be used to locate the specific location of the survivors or victims through multiple monitoring methods such as audio, video, and seismic waves. The device of the utility model can detect areas that cannot be reached by human power, and transmit the collected sound in a small space to the monitor or headphones at the back end for real-time display or monitoring, so that search and rescue personnel can understand the real situation in the small space, quickly find and locate survivors or victims, and buy more time for rescue work.

[0004] However, there are some issues that need to be considered when implementing the above technical solutions: first, the device is used at disaster relief sites where the on-site environment is relatively harsh. Dust entering the device will affect the stability of the electronic components inside the device, resulting in detection errors, and the working range of a single micro-vibration sensor probe is limited. Second, dust will adhere to the camera, affecting camera shooting, causing difficulty in operation, and prone to accidents. Utility Model Content

Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0025] Please refer to Figures 1-4 , an embodiment provided by the present utility model: a micro-vibration vital sign detection device, including a main body 1 and a detection mechanism 3. Traveling wheels 2 are provided on the outer side of the main body 1, a detection mechanism 3 is provided on one side of the traveling wheels 2, a heat insulation plate 301 is provided inside the main body 1, and a maintenance cover 302 is provided on the top of the main body 1.

[0026] Specifically, cameras 303 are provided on the left and right sides of the maintenance cover 302. The cameras 303 are fixedly connected to the main body 1. A sealing plate 304 is rotatably connected to one side of the cameras 303. The sealing plate 304 is in close fit with the cameras 303. Glass 305 is provided inside the sealing plate 304. At the disaster relief site, the working environment is relatively harsh, there will be more floating dust, which is likely to affect the operation of the cameras 303. The sealing plate 304 protects the cameras 303 to prevent dust from affecting the operation of the cameras 303. The cameras 303 can perform shooting work through the glass 305.

[0027] Specifically, the heat insulation plate 301 divides the interior of the main body 1 into two independent spaces. The space below the main body 1 is a sealed space. A signal processor 306 is connected to the bottom of the heat insulation plate 301. A battery 307 is provided below the signal processor 306. A refrigerator 308 is provided above the heat insulation plate 301. A heat conduction pipe 309 is connected to the outside of the refrigerator 308. The heat conduction pipes 309 are evenly distributed in the space below the main body 1. After the space below the main body 1 is sealed, it can prevent dust from entering and affecting the operation of the signal processor 306 and the battery 307, and heat dissipation cannot be carried out through air flow. The refrigerator 308 works to transport the coolant to the space below the main body 1 through the heat conduction pipes 309 for cooling, preventing the signal processor 306 and the battery 307 from generating heat and affecting the operation stability at high temperatures, resulting in detection errors.

[0028] Specifically, a filter box 310 is provided on the left side of the refrigerator 308. An air inlet 311 is opened on one side of the filter box 310. An air pump 312 is connected to the left side of the filter box 310. The air pump 312 works to draw air from the air inlet 311 into the filter box 310 for filtration, and then send it to the cleaning nozzle 313.

[0029] Specifically, a cleaning nozzle 313 is provided outside the camera 303. The cleaning nozzle 313 is fixedly connected to the main body 1. The cleaning nozzle 313 is connected to the air pump 312 through a pipeline. The cleaning nozzle 313 is provided with two nozzles. The cleaning nozzle 313 sprays gas to clean the glass 305, blows away the adsorbed dust, keeps the glass 305 clear, and avoids affecting the observation of the camera 303.

[0030] Specifically, a mounting frame 314 is sleeved inside the filter box 310. A filter screen 315 is provided on the inner side of the mounting frame 314. A buckle 316 is connected to the top of the mounting frame 314. The mounting frame 314 and the filter box 310 form a fixed structure through the buckle 316. Open the buckle 316, pull out the mounting frame 314, and replace the filter screen 315, which is convenient, fast, and saves rescue time.

[0031] Specifically, micro-vibration detectors 317 are provided on the front and rear sides of the maintenance cover 302. Multiple groups of micro-vibration detectors 317 are provided. The micro-vibration detectors 317 are electrically connected to the signal processor 306. Multiple micro-vibration detectors 317 can accurately locate the source of vibration and more accurately determine the position of the trapped person.

[0032] Working principle: First, the device moves through the traveling wheels 2, and the camera 303 takes pictures of the surrounding environment for easy operation. At the disaster relief site, the working environment is relatively harsh, and there will be a lot of floating dust, which is likely to affect the operation of the camera 303. The sealing plate 304 protects the camera 303 to prevent dust from affecting the operation of the camera 303. The camera 303 can take pictures through the glass 305. At the same time, multiple micro-vibration detectors 317 can accurately locate the source of vibration and more accurately determine the position of the trapped person. During operation, the refrigerator 308 works to transport the coolant through the heat conduction pipe 309 to the space below the main body 1 for cooling, preventing the signal processor 306 and the battery 307 from heating up and affecting the operation stability at high temperatures, resulting in detection errors. When the surface of the glass 305 is blocked by dust, the air pump 312 works to draw air from the air inlet 311 into the filter box 310 for filtration, and then send it to the cleaning nozzle 313. The cleaning nozzle 313 sprays gas to clean the glass 305, blows away the adsorbed dust, keeps the glass 305 clear, and avoids affecting the observation of the camera 303. After the filter screen 315 is blocked, open the buckle 316, pull out the mounting frame 314, and replace the filter screen 315, which is convenient, fast, and saves rescue time.
