Description

Technical Field

[0001] The present invention relates to the field of geological disaster rescue technology, and in particular to a deep gas detection personnel search and rescue device for efficiently searching for buried personnel after geological disasters such as earthquakes, landslides, mud-rock flows, and collapses. Background Art

[0002] After a geological disaster such as an earthquake occurs, buried people are usually in a state where they cannot do exercises such as turning over or raising their arms. Since the buried environment is very airtight, the buried people will seriously lack oxygen after a certain period of time and cannot maintain normal breathing, and then enter a coma. At the same time, the buried people cannot obtain food and water, and the lack of water for more than three consecutive days will make the health of the buried people extremely worse. Under the above-mentioned harsh living conditions, the survival rate of the buried people during 72 hours will show a decreasing trend as time goes by. On the first day (i.e. within 24 hours), the survival rate of the rescued people is about 90%, on the second day, the survival rate is about 50%-60%, and on the third day, the survival rate is about 20%-30%. However, if oxygen can be continuously supplied to the space under the nose of a certain buried person during this period, and water and fluid food can be directly supplied to the mouth of the buried person, then the survival rate of the buried person can undoubtedly be greatly improved. However, existing geological disaster rescue equipment lacks the ability to accurately locate the mouth and nose of a buried person, continuously provide oxygen to the area near the nose, or directly replenish water and fluids to the mouth.

[0017] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 1 It is a front view of a schematic structural diagram of a deep gas detection and rescue device according to the present invention;

[0019] Figure 2 A side view of the gas composition analysis device portion of the deep gas detection and rescue device of the present invention;

[0021] Trained dogs can use smell to find survivors buried under the rubble of buildings. This is because human body odor will overflow through the air flow channels within the building ruins, that is, human body odor must flow out through the air flow channels that exist in the collapsed building rubble. This also means that by following this air flow channel that can overflow the odor, the buried people can be found.

[0022] When a building collapses and a person is buried under the rubble, simply knowing that there are living people underneath is far from enough, because the buried person's head may be in a very small, poorly ventilated space. Under the condition of lack of oxygen, the buried person will soon become comatose or die due to lack of oxygen. Therefore, being able to quickly provide oxygen to the space where the buried person's head is located is of great significance to whether the buried person can be rescued smoothly. However, various existing life-saving equipment can usually only be used to find and determine whether there are living buried people in the ruins, or rescue workers have learned that there are living buried people under a certain building through the buried person's cries for help. Even in this case, because the rescue workers do not know the path to insert the oxygen supply pipe into the space where the buried person's head is located, it is still difficult for outside rescue workers to effectively provide oxygen to the buried person using existing technology, and to provide the buried person with drinking water, food, and medical treatment when necessary. The present invention can solve this technical problem that cannot be solved by existing technology.

[0023] The deep gas detection and rescue device of the present invention is as follows: Figure 1 、 Figure 2 and Figure 3 As shown, it includes a gas hose 1 and a liquid infusion hose 2 arranged in parallel, and the front end of the gas hose 1 or the liquid infusion hose 2 is provided with a lighting lamp 14, a wired intercom and a camera. The gas outlet of the gas hose 1 is located behind the liquid outlet of the liquid infusion hose 2. A plurality of odor collection hoses 3 are arranged in parallel on the outer wall of the gas hose 1 and / or the liquid infusion hose 2. The air inlets of the plurality of odor collection hoses 3 are arranged spaced apart from front to back along the outer wall of the gas hose 1 and / or the liquid infusion hose 2, and the air outlet of each odor collection hose 3 is respectively communicated with the air inlet of the gas composition analysis device 4;

[0024] The liquid inlet of the liquid infusion hose 2 is communicated with the liquid outlet of the drinking water delivery pipe 6 and the liquid outlet of the nutrient solution delivery pipe 7, respectively. The drinking water delivery pipe 6 and the nutrient solution delivery pipe 7 are respectively connected in series with a hydraulic pump 8 and an electric shut-off valve 9. The liquid inlet of the drinking water delivery pipe 6 is communicated with a drinking water storage tank 10, and the liquid inlet of the nutrient solution delivery pipe 7 is communicated with a nutrient solution storage tank 11.

[0025] The gas delivery hose 1 is connected in series with a ventilation pump 12 and an electric valve, and the air inlet of the gas delivery hose 1 is connected to the oxygen storage tank 13 and / or the outside atmosphere.

[0026] When the deep gas detection and rescue device of the present invention is used, the gas supply hose 1, the liquid infusion hose 2 and the multiple odor collection hoses 3 that are bound together can be inserted into the gaps between the various objects in the ruins of the building, or the outermost obstruction can be opened by drilling first, and then the gas composition in the gap or borehole can be detected. If it is found that the concentration of carbon dioxide gas, the concentration of volatile fatty acids, the concentration of amino acids, and the concentration of lactic acid therein are higher than the environmental values, the gas supply hose 1, the liquid infusion hose 2 and the multiple odor collection hoses 3 can be further inserted into the gap, and the concentration of carbon dioxide gas, the concentration of volatile fatty acids, and the concentration of amino acids flowing out of each odor collection hose 3 can be continuously measured during the insertion process. If it is found that the concentration of carbon dioxide gas, volatile fatty acid, amino acid and lactic acid collected by the odor collection hose 3 at the front end is unchanged or increases, the gas supply hose 1, the liquid infusion hose 2 and the multiple odor collection hoses 3 can be inserted inward. If it is found that the concentration of carbon dioxide gas, volatile fatty acid, amino acid and lactic acid collected by the odor collection hose 3 at the front end is reduced or disappears and cannot be measured, the gas supply hose 1, the liquid infusion hose 2 and the multiple odor collection hoses 3 need to be appropriately retracted outward for a certain distance, and then with the help of the gas supply hose 1 or the liquid infusion hose 2, the lighting lamp 14 and the camera at the front end are changed to insert the gas hose 1, the liquid infusion hose 2 and the multiple odor collection hoses 3, so as to continuously measure the concentration of various gases, and then move forward along the gap where the concentration of carbon dioxide gas, volatile fatty acids, amino acids and lactic acid are larger, and then measure and move forward again, and the position of the trapped person's nose can be found along the curved gap, and then the intercom at the front end of the gas hose 1 or the liquid infusion hose 2 is turned on to inquire about the status of the trapped person, and at the same time, with the help of the lighting lamp 14 and the camera, the end of the liquid infusion hose 2 is sent into the mouth of the trapped person, and the ventilation pump 12 is started at the same time. The tube 1 delivers outside air or oxygen stored in the oxygen storage tank 13 to the space near the nose of the trapped person for oxygen supplementation, and through the infusion hose 2, the drinking water delivery pipe 6 and the nutrient solution delivery pipe 7 are started as needed. The hydraulic pump 8 is connected in series, and the water stored in the drinking water storage tank 10 is directly delivered to the mouth of the trapped person through the drinking water delivery pipe 6, or the nutrient solution stored in the nutrient solution storage tank 11 is directly delivered to the mouth of the trapped person through the nutrient solution delivery pipe 7. This can prevent the buried person from becoming unconscious or dying due to lack of oxygen, and prevent the buried person from becoming unconscious or dying due to lack of water or nutritious food, so that the buried person can hold on for a longer time and be rescued.

[0027] As a further improvement of the present invention, the distance between the air outlet of the above-mentioned gas delivery hose 1 and the liquid outlet of the liquid infusion hose 2 is greater than 50 mm, the number of the odor collection hoses 3 is 6-24, and the distance between the air inlets of adjacent odor collection hoses 3 is 30 mm-100 mm.

[0028] As a further improvement of the present invention, each of the above-mentioned odor collection hoses 3 is respectively connected in series with an air filter, the aperture of the air supply hose 1 is larger than the aperture of the liquid infusion hose 2, and the aperture of the liquid infusion hose 2 is larger than the aperture of the odor collection hose 3.

[0029] As a further improvement of the present invention, the gas composition analysis device 4 includes an XYZ three-axis mobile platform 21, a Z-axis slider 22 of the XYZ three-axis mobile platform 21 is mounted with an injector 23, a needle 24 of the injector 23 is arranged vertically downward, and a plurality of vacuum cylinders 25 are arranged in parallel in the vertical direction on the workbench of the XYZ three-axis mobile platform 21;

[0030] The XYZ three-axis mobile platform 21, also known as an XYZ high-precision mobile platform or a three-coordinate high-precision mobile platform, is a platform capable of precise movement in the X, Y, and Z directions. The XYZ platform primarily consists of an X-axis moving section, a Y-axis moving section, and a Z-axis moving section. The couplings for each axis can be connected to a servo motor for automatic adjustment, or directly connected to a rotating disk for manual adjustment.

[0031] The components of the three-coordinate precision mobile platform in the X, Y, and Z directions include their own transmission systems, guide systems, drive systems, digital displacement measurement systems based on capacitive sensors, and corresponding support components.

[0032] The XYZ three-axis mobile platform 21 is typically designed with its X-axis base plate fixed to a base, its Y-axis base plate fixed to the X-axis movable carriage, and its Z-axis base plate secured to the Y-axis carriage via angle irons. The measurement probe can be mounted on the two-axis carriage via a bracket. The up-and-down movement of the Z-axis carriage enables Z-axis movement of the needle 24 of the injector 23. All Z-axis components are mounted on the Y-axis carriage, allowing the Y-axis carriage to achieve Y-axis movement of the needle 24. Similarly, the XYZ three-axis mobile platform 21 can also achieve X-axis movement of the needle 24.

[0033] When the deep gas detection and rescue device of the present invention is in use, the gas chromatograph 28 can be used to measure the concentration of carbon dioxide gas, the concentration of volatile fatty acids, the concentration of amino acids, the concentration of lactic acid, the concentration of cadaverine, the concentration of putrescine, the concentration of hydrogen sulfide and the concentration of methane in the air near the search and rescue area, and record these basic data.

[0034] When in use, the Z-axis slider 22 of the XYZ three-axis moving platform 21 can move in three-dimensional space above each vacuum cylinder 25, and can allow the needle 24 of the sampler 23 to be aligned with a vacuum cylinder 25 whose gas needs to be extracted for component analysis.

[0035] A gas inlet 26 and an exhaust port are provided on the side wall of the upper portion of each vacuum cylinder 25. A rubber stopper 18 is provided on the top of each vacuum cylinder 25. A piston 19 is provided in each vacuum cylinder 25. A piston driving cylinder 20 is provided below each vacuum cylinder 25. Each piston driving cylinder 20 is arranged in a vertical direction. The piston rod of each piston driving cylinder 20 is respectively installed and connected to the corresponding piston 19 located above it.

[0036] The gas inlet 26 of each of the vacuum cylinders 25 is connected to the gas outlet of an odor collection hose 3. The gas inlet 26 of the vacuum cylinder 25 or the odor collection hose 3 is provided with an inlet check valve 30 that allows gas to enter the vacuum cylinder 25. The exhaust port on the upper part of each vacuum cylinder 25 is provided with an exhaust check valve 31 that allows gas to exit the vacuum cylinder 25.

[0037] The sample injector 23 can extract the gas in each vacuum cylinder 25 and send it to the sampling system 29 of the gas chromatograph 28. The sampling system 29 of the gas chromatograph 28 is installed on the workbench of the XYZ three-axis moving platform 21.

[0038] During use, the piston 19 provided in a certain vacuum cylinder 25 moves upward under the drive of the piston-driven cylinder 10 or the piston-driven oil cylinder or the linear drive motor, which compresses the gas located in the upper piston 19 in the vacuum cylinder 25, allowing the gas located in the upper piston 19 in the vacuum cylinder 25 to be discharged from the exhaust one-way valve 31 provided at the exhaust port, which allows the gas to be discharged from the vacuum cylinder 25. The piston 19 provided in a certain vacuum cylinder 25 moves downward under the drive of the piston-driven cylinder 10 or the piston-driven oil cylinder or the linear drive motor, which forms a negative pressure in the cavity of the upper piston 19 in the vacuum cylinder 25, thereby allowing the air in each odor collection hose 3 to enter through the air inlet one-way valve 30 at the gas inlet 26 of the vacuum cylinder 25. After multiple cycles of pumping and exhausting, most of the original air in each odor collection hose 3 can be replaced. At this time, the gas sucked into the vacuum cylinder 25 contains the gas collected by each odor collection hose 3 from the ruins of the collapsed building.

[0039] The needle 24 of the above-mentioned injector 23 can be pushed by the Z-axis slider 22 of the XYZ three-axis moving platform 21 to move downward to pierce the rubber plug 18 provided on the top of a corresponding vacuum cylinder 25, and then the injector 23 extracts the gas inside the vacuum cylinder 25. After completing the extraction of the gas inside the vacuum cylinder 25, the Z-axis slider 2 of the XYZ three-axis moving platform 21 will move the injector 23 upward as a whole, that is, pull out the needle 24 of the injector 23 from the rubber plug 18 on the top of the corresponding vacuum cylinder 25, and then the Z-axis slider 22 of the XYZ three-axis moving platform 21 will move to the injection system of the gas chromatograph 28. At 29, the gas extracted by the sampler 23 is injected into the sampling system 29 of the gas chromatograph 28. The gas chromatograph 28 will immediately measure the concentration of carbon dioxide, volatile fatty acids, amino acids, lactic acid, cadaverine, putrescine, hydrogen sulfide, and methane in the gas. If the analysis finds that the concentration of carbon dioxide, volatile fatty acids, amino acids, and lactic acid in the gas sample is significantly higher than the normal values ​​in the environment previously collected, it indicates that there are living people or animals underground near the source of the gas sample. If the analysis finds that the concentration of cadaverine, putrescine, hydrogen sulfide, and methane in the gas sample is significantly higher than the normal values ​​in the environment, it indicates that there are human or animal remains underground near the borehole.

[0040] The deep gas detection and rescue device of the present invention can obtain the position of the person to be rescued by combining the concentration difference of one or several characteristic compounds in each gas sample and the corresponding tracheal placement position.

[0041] If the analysis finds that the concentration of carbon dioxide gas and / or the concentration of volatile fatty acids and / or the concentration of amino acids and / or the concentration of lactic acid in the gas sample has not increased significantly, and is not much different from the values ​​collected previously, then it indicates that there are no living humans or animals at that depth underground near the source of the gas sample; if the analysis finds that the concentration of cadaverine and / or putrescine and / or the concentration of hydrogen sulfide and / or methane in the gas sample has not increased significantly, and is not much different from the values ​​collected previously from the environment, then it indicates that there are no human or animal remains at that depth underground near the source of the gas sample.

[0042] As a further improvement of the present invention, the gas chromatograph 28 is used to measure the concentration of carbon dioxide gas, volatile fatty acid concentration, amino acid concentration, lactic acid concentration, cadaverine concentration, putrescine concentration, hydrogen sulfide concentration and methane concentration in the gas.

[0043] As a further improvement of the present invention, the gas chromatograph 28 is an online gas chromatograph.

[0044] As a further improvement of the present invention, the above-mentioned vacuum cylinders 25 are arranged in parallel in 2-4 rows along the horizontal direction on the workbench of the XYZ three-axis movable platform 21.

[0045] As a further improvement of the present invention, the number of the above-mentioned odor collection hoses 3 is 10-20, and each of the piston-driven cylinders 20 is connected to the pressure gas storage tank 33 of the air compressor through a solenoid valve 32.

[0046] Example 1

[0047] Assume that regular knocking sounds for help are heard from under a building that has collapsed due to an earthquake. After hearing these distress signals, the rescue workers outside can determine that there are survivors under the collapsed building who need to be rescued. However, it may take a long time from hearing these distress signals to actually rescuing the buried people. In order to prevent the buried people from suffering serious health problems due to lack of oxygen, water and food before this, the rescue workers outside can use five deep gas detection and rescue devices of the present invention to carry out rescue operations at the same time.

[0048] During rescue operations, the gas supply hose 1, the liquid infusion hose 2 and the multiple odor collection hoses 3 of each deep gas detection and rescue device of the present invention can be inserted into the rubble gap at the scene. If the measurement shows that the carbon dioxide concentration in the rubble gap is greater than the carbon dioxide concentration in the surrounding environment, the gas supply hose 1, the liquid infusion hose 2 and the multiple odor collection hoses 3 are continued to be inserted inward. If the measurement shows that the carbon dioxide concentration in the rubble gap is equal to or less than the carbon dioxide concentration in the surrounding environment, the insertion position is immediately changed. If necessary, the outer layer of rubble that is blocking the sound of help can be drilled open with a drill rig according to the location of the sound of help, and then the gas supply hose 1, the liquid infusion hose 2 and the multiple odor collection hoses 3 are inserted inward and the carbon dioxide concentration inside is measured. If the measurement shows that the carbon dioxide concentration in the rubble gap is equal to or less than the carbon dioxide concentration in the surrounding environment, the insertion position is immediately changed. If necessary, the outer layer of rubble that is blocking the sound of help can be drilled open with a drill rig, and then the gas supply hose 1, the liquid infusion hose 2 and the multiple odor collection hoses 3 are inserted inward and the carbon dioxide concentration inside is measured. If the carbon dioxide concentration in the rubble gap is found to be equal to or less than the carbon dioxide concentration in the nearby environment, first pull out the gas hose 1, the liquid replenishment hose 2 and the multiple odor collection hoses 3, continue to use the drill to drill inward for a distance, and then reinsert the gas hose 1, the liquid replenishment hose 2 and the multiple odor collection hoses 3 and measure the carbon dioxide concentration inside. If the measurement finds that the carbon dioxide concentration inside is sharply increased relative to the carbon dioxide concentration in the environment, it indicates that the space here has been connected to the air that the buried people can breathe. At this time, you can use touch to continue to insert the gas hose 1, the liquid replenishment hose 2 and the multiple odor collection hoses 3, and continue to measure the carbon dioxide concentration inside according to the situation. Then you can continue to insert the gas hose 1, the liquid replenishment hose 2 and the multiple odor collection hoses 3 into the gap. Multiple odor collection hoses 3 are provided, and the concentration of carbon dioxide gas, volatile fatty acid concentration, amino acid concentration, and lactic acid concentration flowing out of each odor collection hose 3 are continuously measured during the insertion process. If it is found that the concentration of carbon dioxide gas, volatile fatty acid concentration, amino acid concentration, and lactic acid collected by the odor collection hose 3 at the front end is unchanged or the concentration increases, the gas supply hose 1, the liquid replenishment hose 2, and the multiple odor collection hoses 3 can be further inserted. If it is found that the concentration of carbon dioxide gas, volatile fatty acid concentration, amino acid concentration, and lactic acid collected by the odor collection hose 3 at the front end is reduced or disappears and cannot be measured, the gas supply hose 1, the liquid replenishment hose 2, and the multiple odor collection hoses 3 need to be inserted. The tube 3 is appropriately retracted outward for a certain distance, and then the insertion direction is changed with the help of the lighting lamp 14 and the camera provided at the front end of the gas hose 1 or the liquid infusion hose 2, and then the gas hose 1, the liquid infusion hose 2 and the multiple odor collection hoses 3 are inserted inward, and the concentrations of various gases are continuously measured. Then, the concentration of carbon dioxide gas, volatile fatty acid concentration, amino acid concentration, and lactic acid concentration are moved forward along the gap. After measuring and moving forward again, the nose of the trapped person can be found along the curved gap. Then, the intercom provided at the front end of the gas hose 1 or the liquid infusion hose 2 is turned on to inquire about the status of the trapped person. At the same time, the end of the liquid infusion hose 2 is sent into the mouth of the trapped person with the help of the lighting lamp 14 and the camera, and the ventilation pump 12 is started at the same time.The air hose 1 delivers outside air or oxygen stored in the oxygen storage tank 13 to the space near the trapped person's nose for oxygen supplementation. Furthermore, the drinking water delivery pipe 6 and the nutrient solution delivery pipe 7, each connected in series with a hydraulic pump 8, are activated as needed via the fluid delivery hose 2. Water stored in the drinking water storage tank 10 is delivered directly to the trapped person's mouth via the drinking water delivery pipe 6, or nutrient solution stored in the nutrient solution storage tank 11 is delivered directly to the trapped person's mouth via the nutrient solution delivery pipe 7. This prevents the buried person from falling into a coma or dying from lack of oxygen, water, or nutritious food, allowing the buried person to survive longer and be rescued.

[0049] If it is determined by touch that the gas supply hose 1, the liquid infusion hose 2 and the multiple odor collection hoses 3 at a certain location cannot be inserted further, but it can be determined that the air at the insertion position can be connected to the breathing air of the buried person, it can be judged according to the situation whether to start the ventilation pump 12 directly at this position to supply outside air or oxygen stored in the oxygen storage tank 13 through the gas supply hose 1 for oxygen supplementation, or to pull out the gas supply hose 1, the liquid infusion hose 2 and the multiple odor collection hoses 3 and reinsert them after changing their position.

[0050] Due to the obstruction of rubble, it is only necessary to use the lighting 14, wired intercom and camera after the insertion ends of the gas hose 1, the fluid infusion hose 2 and the multiple odor collection hoses 3 are close to the buried person. The use of the lighting 14, wired intercom and camera can help rescuers to directly deliver the outlet of the fluid infusion hose 2 into the mouth of the buried person, so as to facilitate the buried person who is unable to move to obtain drinking water and nutrient solution supplements.

[0051] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineers and technicians in this field should fall within the scope of protection determined by the claims of the present invention.
