Detailed Implementation

[0027] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0028] One specific embodiment of the present invention discloses a drilling-type human odor sensing device, such as... Figure 1 As shown, it includes a walking unit 1, a drilling unit 2, a connecting unit 3, and a gas extraction unit 4.

[0029] The walking unit 1 and the drilling unit 2 are connected by the connecting unit 3; the gas extraction unit 4 is located at the lower end of the drilling unit 2 and is used to collect and transport formation gas.

[0030] To address the issue of disconnect between drilling and gas extraction processes in traditional equipment, which affects the accuracy of gas detection and the efficiency of rescue operations, this embodiment connects the gas extraction unit 4 with the drilling unit 2. During or after drilling operations, gas samples escaping from the formation are collected. Formation gas collection can be completed simultaneously during drilling, achieving integrated drilling and gas extraction operations. This shortens the time required for rescue and detection operations and meets the timeliness requirements of emergency rescue. Furthermore, the gas extraction unit 4 is lowered synchronously with the drilling unit 2, enabling precise collection of formation gas at a specified depth, improving the specificity and accuracy of gas sample detection.

[0031] The walking unit 1 is the foundation for the movement and load-bearing of the entire machine, providing a stable mobile platform and working environment for drilling, gas production, and gas analysis operations.

[0032] Specifically, such as Figure 1 As shown, the walking unit 1 includes a driver's cab 11 and a chassis 12. The chassis 12 adopts a tracked walking structure to adapt to complex terrain environments. The driver's cab 11 is located on the upper part of the chassis 12.

[0033] Furthermore, the walking unit 1 also includes shock absorbers 13. In this embodiment, the driver's cab 11 is fixed to the chassis 12 by the evenly distributed shock absorbers 13. The shock absorbers 13 buffer the transmission of vibration to the driver's cab 11, improve the operator's work comfort, achieve dual protection of the human-machine working space, and improve the adaptability of the equipment to field operations.

[0034] Furthermore, the walking unit 1 also includes a bulldozer blade 14, which is installed at the front end of the walking chassis 12 and is hydraulically driven to achieve lifting and leveling actions. It is mainly used for cleaning the work site, leveling the ground, and pushing materials.

[0035] Drilling unit 2 is used for downward drilling, such as Figure 2 As shown, it includes a guide assembly 21, a transmission assembly 22, and a drilling assembly 23.

[0036] like Figure 3 As shown, the guide assembly 21 includes a mast 211 and a carriage 212. The mast 211 is the main vertical support frame of the drilling unit 2, providing linear guidance and support for the carriage 212, drill string 231, etc. The carriage 212 is mounted on the mast 211 and can slide up and down along the mast 211, carrying the drilling assembly 23 to realize the feeding and lifting actions of the drill string 231.

[0037] The transmission assembly 22 includes a pressure cylinder 221, a wire rope 222, and a pulley 223. The pressure cylinder 221 is located on one side of the mast 211 and provides drilling pressure through the extension and retraction of its piston rod, working in conjunction with the wire rope 222 to achieve precise feeding of the drill string 231. The pulley 223 is located at the top of the mast 211 and is used to steer and support the wire rope 222. One end of the wire rope 222 is connected to the slide 212, and the other end passes around the pulley 223 at the top of the mast 211 and connects to the drill string 231. Working in conjunction with the pressure cylinder 221, it transmits the cylinder's power to the slide 212, enabling pressurized drilling and rapid lifting of the drill string 231.

[0038] This embodiment adopts a composite transmission structure of "pressure cylinder 221 + pressure wire rope 222 + pulley 223". Through the extension and retraction of the cylinder and the force transmission of the wire rope 222 and pulley 223, the drilling component 23 is driven to move up and down precisely, so as to realize the controllable adjustment of the drilling depth. The feeding and lifting action of the drilling component 23 is more stable and can be dynamically adjusted according to the hardness of the formation, reducing the risk of overload damage to the drill bit 231 during hard rock drilling.

[0039] The drilling assembly 23 includes a drill string 231, a hydraulic motor 232, and a motor reducer 233.

[0040] The drilling tool 231 includes a drill rod 2311, a auger rod 2312, and a drill bit 2313.

[0041] To address the issue of low purity in the gas source and the resulting media contamination affecting detection accuracy, this embodiment abandons traditional mud drilling and pneumatic drilling methods, instead employing a spiral drill bit 2313 and a spiral drill rod 2312. The spiral drill bit 2313 has a spiral structure, directly breaking up the formation while simultaneously using spiral blades to transport and discharge drill cuttings upwards, achieving efficient self-discharge of cuttings. This reduces media contamination or interference from impurities in the gas return channel, improving the purity and continuity of formation gas collection.

[0042] The spiral extension rod 2312 is used to extend the length of the drill pipe 2311 to accommodate different drilling depths.

[0043] The hydraulic motor 232 is mounted on the slide 212 and is used to drive the auger drill rod 2311 to rotate. The upper end of the drill rod 2311 is connected to the output end of the motor reducer 233, and the lower end is connected to the auger drill bit 2313, transmitting rotational power and axial pressure to the formation. Drill cuttings are transported upward to the ground by the rotation of the auger blades of the auger drill rod 2311, completing self-discharge of cuttings.

[0044] Furthermore, the drilling unit 2 also includes a duct reel 24, a conductive ventilation slip ring 25, a hose reel, and a sheath 26. The duct reel 24 is installed at the top of the mast 211 and is used to retract and extend the air supply hose to provide compressed air or other media for drilling operations, ensuring the needs of slag removal, cooling the drill bit 2313, etc.

[0045] The conductive venting slip ring 25 is coaxially arranged with the gas hose reel 24 and is used for continuous transmission of electrical signals and gas medium during rotation. The sheath 26 is wrapped around the lower end of the drill pipe 2311 at the connection with the gas production unit 4, protecting the drill string 231 and the gas production interface, preventing the intrusion of formation debris, mud, etc., and ensuring unobstructed gas production channels.

[0046] In use, drilling unit 2 is based on mast 211. The slide 212 is driven to move up and down along mast 211 by pressurizing cylinder 221 and pressurizing wire rope 222, providing axial pressure to motor reducer 233 and drill rod 2311. Motor reducer 233 drives drill rod 2311 to rotate, driving auger bit 2313 to break the formation. Gas hose reel 24 and conductive ventilation slip ring 25 synchronously supply medium and signal. Sheath 26 protects the interface and connects to gas production unit 4, finally completing the downward drilling operation.

[0047] like Figure 4As shown, the connecting unit 3 connects the traveling unit 1 and the drilling unit 2, and includes a connecting rod 31, a first connecting cylinder 32, and a second connecting cylinder 33. The two ends of the connecting rod 31 are respectively hinged to the drilling unit 2 and the traveling unit 1, the two ends of the first connecting cylinder 32 are respectively hinged to the drilling unit 2 and the connecting rod 31, and the two ends of the second connecting cylinder 33 are respectively hinged to the connecting rod 31 and the traveling unit 1.

[0048] For example, a connecting seat 34 is provided on the slide 212, and an adapter seat 35 is provided on the chassis 12. One end of the first connecting cylinder 32 is hinged to the connecting seat 34, and the other end is hinged to the connecting rod 31; one end of the second connecting cylinder 33 is hinged to the adapter seat 35, and the other end is hinged to the connecting rod 31. When the drill string 231 drills downward, the angle of the drill string 231 is adjusted by the connecting rod 31 and the first connecting cylinder 32 and the second connecting cylinder 33 to improve drilling accuracy.

[0049] like Figure 3 As shown, in order to achieve simultaneous drilling and gas extraction, solve the problem of disconnect between traditional drilling and gas extraction, and improve the timeliness and accuracy of gas extraction, the gas extraction unit 4 is located at the lower end of the drilling unit 2 and integrated into the drill bit 2313. During or after drilling operations, the gas extraction unit 4 is used to collect, filter, temporarily store, and transport gas samples escaping from the formation, realizing integrated drilling and gas extraction operations.

[0050] To address the issue of low purity in the collected gas, containing solid particles that affect the accuracy of detection, such as... Figure 5 As shown, the gas extraction unit 4 in this embodiment includes a composite filter element 42 and a composite drill bit 41. The composite drill bit 41 is located at the bottom of the unit and adopts a conical tip design, directly participating in formation fracturing operations. The gas extraction chamber of the composite drill bit 41 is equipped with a high-permeability steel ball die-cast filter element, which allows gas and water to pass through while effectively isolating solid impurities such as mud, reducing blockage of the gas extraction channel. The composite filter element 42 is located above the composite drill bit 41, forming a double-layer filtration structure with the steel ball die-cast filter element, further filtering drill cuttings, mud, and other impurities, reducing the entry of solid particles into the gas extraction channel, improving the purity of gas extraction, and ensuring smooth pipeline flow.

[0051] Furthermore, the gas extraction unit 4 also includes a composite cavity 43 and an integrated airbag 44.

[0052] To address the issues of interference between gas storage and the working environment of the gasbag during gas extraction, susceptibility to contamination of the gas extraction channel, and low gas transmission efficiency, this embodiment incorporates a composite cavity 43 comprising a first cavity 431 and a second cavity 432. The first cavity 431 serves as a gas storage and transmission cavity, connecting the integrated gasbag 44 to the external gas extraction pipeline, and is used for temporary storage of the extracted formation gas. The second cavity 432 is the mounting cavity for the integrated gasbag 44, providing a sealed working environment for the integrated gasbag 44, and simultaneously accommodating the counterweight and piping components of the gasbag 444.

[0053] To solve the problem of inaccurate control of gas delivery, such as Figure 6 As shown, in this embodiment, the integrated airbag 44 includes an inhalation tube 441, an inhalation tube 442, a steel wire 443, and an airbag 444.

[0054] One end of the suction pipe 441 is connected to the first cavity 431, and the other end is connected to the airbag 444, used to draw formation gas into the airbag 444 for storage; the blowing pipe 442 is connected to the airbag 444, and can inject gas into the airbag 444 or expel the collected gas, realizing the inflation and deflation control of the airbag 444. The blowing pipe 442 includes an inlet pipe and a gas outlet pipe. The inlet pipe introduces air and blows up the airtight bulb of the airbag 444 to isolate formation gas from surface gas and avoid gas mixing affecting detection accuracy; the gas outlet pipe takes gas and connects to the gas analysis unit 5 to transport the collected formation gas to the analysis unit for analysis.

[0055] To address the limitations of traditional rigid gas extraction containers in deep holes and irregular formations, and their susceptibility to jamming and damage during drilling vibrations, the airbag 444 is an elastically sealed cavity that can flexibly expand and contract according to the formation space. This expansion and contraction facilitates gas intake and exhaust, adapting to the gas extraction environment of irregular formations and enabling the temporary storage and transport of formation gas. After gas extraction is completed, the air intake pipe is deflated, the airbag 444 tightens, and quickly resets, allowing drilling to continue for deeper exploration and gas extraction. The motor in drilling unit 2 inflates the airbag 444.

[0056] Furthermore, to address the issue of gas production components shifting or becoming entangled due to ground vibrations and drill rod swaying during drilling, which can cause blockages in the middle of the gas path, the integrated airbag 44 also includes an upper counterweight 445 and a lower counterweight 446. The upper counterweight 445 and the lower counterweight 446 are respectively fixed to the upper and lower ends of the steel wire 443. The steel wire 443 passes through the center of the airbag 444, with the upper end connected to the lifting mechanism of the drill bit 231 and the lower end connected to the lower counterweight 446. Gravity keeps the airbag 444 in a vertical position, preventing it from shifting or becoming entangled inside the cavity, ensuring unobstructed gas flow, and guaranteeing stable operation of the airbag 444 during drilling.

[0057] Compared with the prior art, this embodiment adopts a partitioned composite cavity 43. The first cavity 431 temporarily stores the gas, and the second cavity 432 is used to install the airbag 444. The expansion and contraction of the elastic airbag 444 realizes the collection, temporary storage and transportation of the formation gas. In conjunction with the air intake pipe blowing up the airtight ball to isolate the surface gas, the gas sampling pipe delivers the sample in a directional manner, avoids gas mixing and improves the detection accuracy.

[0058] To address the issues of easy contamination of the gas extraction channel and low gas transmission efficiency affecting detection efficiency, the gas extraction unit 4 further includes an integrated core tube 45. The integrated core tube 45 is located inside the drill bit 2313, and the suction pipe 441, blowing pipe 442, steel wire 443, and air bag 444 are all housed within it. On one hand, the integrated core tube 45 can be lowered synchronously with the drill rod 2311, enabling simultaneous drilling and gas extraction without the need for separate tripping of the drill string 231, thus improving rescue efficiency. On the other hand, the integrated core tube 45 forms a gas transmission channel inside the drill rod 2311. The integrated core tube 45 is lowered synchronously with the drill pipe 2311. During drilling, the collected formation gas can be directly transmitted upward through the integrated core tube 45, reducing the contamination of the gas by drill cuttings and soil when it is transmitted outside the drill pipe 2311, thus improving the purity of the gas sample. At the same time, the built-in design allows the integrated core tube 45 to be protected by the drill pipe 2311, reducing the scraping and damage to the integrated core tube 45 by the borehole wall rocks and debris during drilling, and shortening the gas transmission path, reducing gas loss and mixing, allowing the collected gas to be quickly transmitted to the subsequent analysis unit, thus improving detection efficiency.

[0059] It should be noted that the integrated core tube 45 and the airbag 444 are made of polyurethane material to avoid reaction with gas and ensure the authenticity and reliability of the test data.

[0060] Once the drill string 231 reaches the designated depth in the formation, the integrated core tube 45 is lowered to the bottom of the drill pipe 2311, and gas samples are collected simultaneously during the drilling process. During drilling, the gas bladder 444 is inflated and moves downward synchronously with the drill pipe 2311, ensuring the coordination between the gas collection and drilling actions.

[0061] In use, the gas extraction unit 4 is lowered into the formation simultaneously with the drilling unit 2. After the composite drill bit 41 breaks the formation, the formation gas is filtered by the composite filter element 42 and enters the first cavity 431. Then, it is sucked into the air bag 444 through the suction pipe 441 for temporary storage. When gas needs to be delivered, the air bag 444 is pressurized through the blowing pipe 442 to discharge the collected gas to the gas analysis unit 5. The steel wire 443 works in conjunction with the upper counterweight 445 and the lower counterweight 446 to keep the air bag 444 stable during drilling vibration and cavity movement, realizing the integrated gas extraction function of "drilling-filtering-collection-temporary storage-delivery".

[0062] Furthermore, a gas analysis unit 5 is also included. The gas analysis unit 5 is used for gas composition analysis and total gas content detection. The gas analysis unit 5 is electrically connected to the drilling unit 2. As one possible embodiment, a flexible hose connection is used, which can be routed down into the drill pipe 2311.

[0063] Specifically, such as Figure 7 As shown, the gas analysis unit 5 includes a component analysis instrument 51, a total characteristic analysis instrument 52, a headspace pretreatment device 53, and a gas cylinder.

[0064] The total characteristic analyzer 52 performs rapid screening for total sulfur, nitrogen, and carbon, with a detection time ≤10s. The component analyzer 51 uses gas chromatography for precise screening, with a detection time ≤90s. The total characteristic analyzer 52 covers characteristic gaseous markers of living humans / animals, quickly determining the possibility of living humans / animals / corpses in the buried ambient air by measuring total sulfur, total nitrogen, and total carbon in the sample gas. The component analyzer 51 measures the living environment in real time. After the total characteristic analyzer 52 detects characteristic markers of living humans / animals / corpses, the component analyzer 51 is activated for precise screening. The gas cylinder serves as the gas source, providing the detector with the necessary hydrogen and air. During this process, a pressure reducing valve is installed at the gas cylinder to reduce the output pressure of the high-pressure cylinder from 10-15MPa to the low pressure required by the chromatograph (0.2-0.5MPa). The inert gas is controlled into a stable gas flow through the carrier gas system, and the thrust generated by its physical flow moves the vaporized sample at the injection port forward. Hydrogen is a combustible gas, air is a combustion-supporting gas, and they react with the carrier gas (sample gas). After combustion, the chemical bonds break, causing the organic matter to ionize and generate positive and negative charges. The detection system applies pressure to form an electric field to capture these charges, and the recording system converts them into a chromatogram through an electrometer and signal amplifier. The properties and content of the gas are then displayed in computer software.

[0065] If the soil contains water, use headspace pretreatment equipment 53 for drying pretreatment.

[0066] In this embodiment, the gas analysis unit 5 includes a total characteristic analyzer 52 and a component analyzer 51, forming a dual gas analysis system of "rapid screening + precise detection" to achieve multi-dimensional formation gas detection and provide data support for the safety of rescue operations.

[0067] Furthermore, it also includes shock absorbers 13 and fixed brackets. The component analysis instrument 51, the characteristic total analysis instrument 52, and the headspace pretreatment equipment 53 are installed in the driver's cab 11 through the shock absorber brackets, providing a dedicated mounting base for the gas analysis unit 5, reducing the interference of the whole machine vibration on the gas analysis instrument, and ensuring the detection accuracy and equipment stability.

[0068] Furthermore, it also includes an air conditioning system, which is connected to the gas analysis unit 5 through pipelines. The air conditioning system can precisely regulate the temperature of the environment in which the gas analysis unit 5 is located, providing a stable and suitable working temperature environment for the gas analysis instrument and avoiding the impact of temperature fluctuations on the test results.

[0069] Furthermore, a display unit 6 is included, used to establish a three-dimensional gas concentration field based on gas data and to visualize it. The display unit 6 includes a depth sensor and an inertial navigation unit. The depth sensor is mounted at the end of the gas hose reel, rotates with the gas hose to detect depth, and receives detection data from the gas analysis unit 5. The inertial navigation unit displays the drilling rig's geographical location and the terrain distribution of the monitoring area, and is integrated into the display platform of the operator's cab 11.
