Description

Technical Field

[0001] The present invention relates to the technical field of gas detection equipment, in particular to a portable gas detection device for emergency rescue. Background Art

[0002] When conducting emergency operations, equipment maintenance, construction, or hot work in the presence of hazardous gases or substances, or in small or medium-sized confined spaces or complex environments, it is often necessary to test and monitor the air composition in the environment to prevent the risk of poor ventilation, the introduction of flammable and explosive materials, toxic and hazardous substances, and hypoxia, thereby ensuring the health and safety of personnel entering the environment. When conducting gas detection in an area, if a fixed gas detection device is not installed in the detection space, a mobile detection method is often used to enhance the safety and convenience of the gas detection process. For example, a drone or remote-controlled robot carrying a gas detection device is used to perform detection at multiple locations in the space. The detection results are then transmitted to an external control platform via wireless transmission. Based on the detection results, the staff can then take appropriate safety measures to ensure the safety of the rescue personnel. For example, if toxic or hazardous gases are present in the space, the rescue personnel must wear protective equipment such as gas masks. If there is a risk of gas explosion in the space, the rescue personnel must wear protective equipment such as explosion-proof clothing. This minimizes the safety risks faced by the rescue personnel during the emergency rescue process and ensures their safety.

[0003] In actual operation, gas leakage and diffusion take a certain amount of time. Therefore, in order to further protect the lives of rescue personnel, it is usually necessary to monitor the gas environment in the environment in real time during the rescue process after preliminary gas detection. However, only using mobile gas detection equipment to detect the gas environment in the space is limited by the movement speed of the mobile equipment and the detection interval at the same location. It is easy to cause the gas detection results to deviate from the actual leakage and diffusion of dangerous gases, resulting in external commanders being unable to accurately judge the safety hazards in the space, and thus the rescue personnel being unable to take corresponding response measures in time.

[0004] That is to say, the existing technology has the problem of poor gas detection accuracy during emergency rescue. Summary of the Invention

[0005] The main purpose of the present invention is to provide a portable gas detection device for emergency rescue, so as to solve the problem of poor gas detection accuracy during emergency rescue in the prior art.

[0010] Furthermore, the unfolding portion further includes a plurality of air outlet channels, which are arranged in the unfolding legs, the air outlet channels are arranged in a one-to-one correspondence with the support legs, and one end of the air outlet channel is connected to the support leg.

[0011] Furthermore, the detection body also includes multiple sealing plates. When the detection mechanism is in the retracted state, the sealing plates are located between the detection body and the unfolded legs. The sealing plates are arranged in a one-to-one correspondence with the air outlet channels, and the other end of the air outlet channels extends to the sealing plates.

[0012] Furthermore, the sealing plate is made of elastic material, and the supporting leg includes: a supporting shell having a telescopic space; a telescopic bag, which is arranged in the telescopic space and is connected to the air outlet channel.

[0013] Furthermore, the rotation axis is located in the middle of the detection body, and the support assembly includes two expansion parts symmetrically arranged along the height direction, and the expansion legs are in an arc shape bent toward the detection body.

[0014] Furthermore, the limit assembly includes two limit rods arranged in parallel, which are telescopically arranged in the extension direction, and the ends of the limit rods are located on the rotation path of the unfolding legs.

After the mobile device drives the portable gas detection device for emergency rescue to the next detection position, the separation mechanism pushes the next detection mechanism. During the movement of the mobile device, all detection mechanisms are scattered at their respective detection positions, thereby meeting the needs of real-time detection of gas environments at multiple different locations, improving the accuracy of gas analysis, and ensuring the safety of rescue workers.

DETAILED DESCRIPTION

[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0034] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0035] The main purpose of the present invention is to provide a portable gas detection device for emergency rescue, so as to solve the problem of poor gas detection accuracy during emergency rescue in the prior art.

[0036] like Figures 1 to 7 As shown, the portable gas detection device for emergency rescue includes a storage mechanism 10, multiple detection mechanisms 20, and a separation mechanism 30. The storage mechanism 10 has an end plate 11, and one side of the end plate 11 has a connection port 12, which is used to connect a mobile device, and the other side of the end plate 11 has a clamping assembly 13; the multiple detection mechanisms 20 can be movably arranged on the clamping assembly 13 along the extension direction of the clamping assembly 13, and the detection mechanism 20 has a storage state set on the storage mechanism 10 and a deployment state separated from the storage mechanism 10. The detection mechanism 20 can switch between the storage state and the deployment state, and different detection mechanisms 20 are used to detect the gas environment at different positions in the rescue space; the separation mechanism 30 is set on the end plate 11, and when the multiple detection mechanisms are in the storage state, at least a part of the separation mechanism 30 can push the detection mechanism closest to the separation mechanism 30 among the multiple detection mechanisms 20, so as to switch the detection mechanism farthest from the separation mechanism 30 among the multiple detection mechanisms 20 from the storage state to the deployment state.

[0037] By storing multiple detection mechanisms 20 on the storage mechanism 10, the mobile device can drive the portable gas detection device for emergency rescue to move to different positions, and the detection mechanisms 20 can be scattered at different positions to perform real-time gas detection at different positions in the rescue space, ensuring accurate feedback on the leakage and diffusion of dangerous gases. By setting the detection mechanism 20 to be able to switch between the storage state and the expanded state, when multiple detection mechanisms 20 are stored, it will not take up too much space and is convenient to carry. After reaching the detection position, the separation mechanism 30 pushes the detection mechanism 20 to separate from the storage mechanism 10 and switch to the expanded state, thereby uniformly detecting the air at the detection position and improving the accuracy of the detection results. Since multiple detection mechanisms 20 are arranged on the storage mechanism 10, after reaching the detection position, during the pushing process of the separation mechanism 30, all the detection mechanisms 20 on the storage mechanism 10 will move until the detection mechanism farthest from the separation mechanism 30 breaks away from the storage mechanism 10 and falls off at the detection position, and the separation mechanism 30 stops pushing. After the mobile device drives the portable gas detection device for emergency rescue to the next detection position, the separation mechanism 30 pushes the next detection mechanism. During the movement of the mobile device, all detection mechanisms 20 are scattered at their respective detection positions, thereby meeting the needs of real-time detection of gas environments at multiple different locations, improving the accuracy of gas analysis, and ensuring the safety of rescue workers.

[0038] like Figure 2 and Figure 3 As shown, the detection mechanism 20 includes a detection body 21, two sets of support assemblies 22, and two sets of limit assemblies 23. The detection body 21 includes a gas detector; the two sets of support assemblies 22 are symmetrically arranged on both sides of the detection body 21, and the support assemblies 22 are rotatably connected to the detection body 21; the two sets of limit assemblies 23 are symmetrically arranged at the top and bottom of the detection body 21, and the limit assemblies 23 have a limit space. At least a portion of the limit assemblies 23 is located on the rotation path of the support assemblies 22. When the detection mechanism 20 switches between the stored state and the deployed state, the position of the support assemblies 22 switches between inside and outside the limit space. The detection body 21 can be used to detect the gas environment and analyze the gas composition, concentration, etc. of the gas environment. By symmetrically arranging the support components 22 on both sides of the detection body 21, the support components 22 can be used to stably support and protect the detection body 21, reducing the chance of damage when the detection body 21 falls. Moreover, after falling to the ground, the detection body 21 can still be supported and supported, so that the detection body 21 is at a certain distance from the ground, ensuring the normal operation of gas detection. Two sets of limit components 23 are arranged at the top and bottom of the detection body 21. When the detection mechanism 20 is in the storage state, it can ensure that the support component 22 is confined within the storage space, reducing the occupied volume. When the detection mechanism 20 falls off, the limit component 23 fails to limit the support component 22, thereby allowing the support component 22 to unfold.

[0039] like Figure 2 As shown, the support assembly 22 includes at least one unfolding portion, the detection body 21 has at least two rotating shafts 214, the unfolding portion is sleeved on the rotating shaft 214, the unfolding portion includes two unfolding legs 221 and a connecting member 222, the unfolding legs 221 are rotatably connected to the detection body 21, and the unfolding legs 221 and the rotating shaft 214 are arranged in a one-to-one correspondence; the connecting member 222 is connected between the two unfolding legs 221, and the connecting member 222 is located at one end of the unfolding leg 221 close to the rotating shaft 214, and the length of the connecting member 222 is adjustable to drive the unfolding leg 221 to rotate. By setting the unfolding legs 221 to rotate on the rotating shaft 214, and setting a length-adjustable connecting piece 222 between the two unfolding legs 221, the two unfolding legs 221 can rotate in different directions when unfolded. The unfolding legs 221 are used to protect the detection body 21, reducing the chance of damage to the detection body 21 when it falls. Moreover, after it falls to the ground, the detection body 21 can also be supported and held, so that there is a certain distance between the detection body 21 and the ground, ensuring the normal progress of gas detection.

[0040] like Figure 2 As shown, the deployment portion further includes a plurality of support legs 223, one end of each of which is fixed to the deployment leg 221, and the other end of each of which can extend away from the detection body 21. This further improves the stability of the support and also increases the distance between the detection body 21 and the ground, thereby improving the accuracy of gas detection.

[0041] like Figure 5 and Figure 6 As shown, the deployment portion further includes a plurality of air outlet channels 224, which are disposed within the deployment legs 221. The air outlet channels 224 are disposed one-to-one with the support legs 223, and one end of the air outlet channel 224 is connected to the support legs 223. The air outlet channels 224 are connected to the support legs 223, allowing gas to be drawn in or out through the air outlet channels 224 during the process of extending or contracting the support legs 223.

[0042] like Figure 5 and Figure 6 As shown, the detection body 21 further includes a plurality of sealing plates 212. When the detection mechanism 20 is in the stowed state, the sealing plates 212 are located between the detection body 21 and the deployment legs 221. The sealing plates 212 are arranged in a one-to-one correspondence with the air outlet channels 224, and the other ends of the air outlet channels 224 extend to the sealing plates 212. In the stowed state, the sealing plates 212 block the other ends of the air outlet channels 224, preventing air from being drawn into the support legs 223 and preventing them from being deployed, thereby minimizing the space occupied by the support legs 223.

[0043] like Figure 5 and Figure 6As shown, sealing plate 212 is made of elastic material, and support leg 223 includes a support shell 225 and a bellows 226. Support shell 225 has a telescopic space; bellows 226 is disposed within the telescopic space and communicates with air outlet channel 224. The telescopic action of bellows 226 draws gas into or out of support leg 223, allowing support leg 223 to extend or fold. Combined with the elastic structure of sealing plate 212, this restricts the inflow and outflow of gas, thereby limiting the movement of support leg 223.

[0044] like Figure 3 As shown, the rotation axis 214 is located in the middle of the detection body 21. The support assembly 22 includes two expansion portions symmetrically arranged along the height direction, and the expansion legs 221 are arc-shaped and curved toward the detection body. This allows multiple support legs 223 to be evenly distributed on the detection body 21, forming an incomplete spherical shape. This not only protects and supports the detection body 21, reducing the chance of damage if the detection body 21 falls, but also supports and supports the detection body 21 after it falls to the ground, so that the detection body 21 is at a certain distance from the ground, ensuring normal gas detection.

[0045] like Figure 2 and Figure 3 As shown, the limiting assembly 23 includes two parallel limiting rods 231, which are telescopically arranged in the extension direction. The ends of the limiting rods 231 are located on the rotation path of the unfolding legs 221. The two limiting rods 231 are arranged at intervals to form a limiting space. When the detection mechanism 20 is in the retracted state, the unfolding legs 221 abut against the limiting rods 231.

[0046] like Figure 7 As shown, both ends of the limiting rod 231 are provided with centrally symmetrical receiving grooves, and the bottoms of the receiving grooves are connected to telescopic springs and telescopic rods so that the length of the limiting rod 231 can be adjusted.

[0047] like Figure 7 As shown, the limiting rod 231 extends parallel to the top of the detection body 21. The detection mechanism 20 also includes two lifting components 24. The lifting components 24 connect the detection body 21 and the limiting rod 231. The lifting components 24 can drive the limiting rod 231 to rise and fall in the height direction.

[0048] like Figure 7As shown, the detection body 21 has a telescopic slot 213 arranged along the height direction, at least a part of the lifting assembly 24 is arranged in the telescopic slot 213, and the lifting assembly 24 includes a lifting spring 241 and a lifting rod 242. The extension direction of the lifting spring 241 is parallel to the extension direction of the telescopic slot 213, and one end of the lifting spring 241 is fixed to the bottom surface of the telescopic slot 213; one end of the lifting rod 242 is connected to the other end of the lifting spring 241, and the other end of the lifting rod 242 is connected to the limit rod 231.

[0049] like Figure 5 As shown, the detection mechanism 20 further includes a plurality of air guide tubes 25 , which are arranged to fit the contour of the detection mechanism 20 . The openings of the plurality of air guide tubes 25 face in different directions, and the air guide tubes 25 are used to introduce gas into the emergency space.

[0050] In emergency rescue operations, in order to reduce the impact of environmental factors on workers and ensure the safety of rescue workers, when the rescue site does not have equipment or systems for automatically detecting the air environment, rescue workers are usually required to detect the air environment in the environment. During the detection process, the application of mobile devices such as remote-controlled robots and drones can not only enhance the convenience and accuracy of automated detection, but also avoid the safety hazards of manual detection. At the same time, in the process of automated detection, in order to maintain continuous detection of the environment, a portable gas detection device for emergency rescue is installed on a robot or drone, and then when moving in the site, multiple detection mechanisms 20 are dispersed through a separation mechanism 30. In the rescue site, and when dispersed, the uniformity of the dispersion of the detection mechanism 20 should be taken into consideration. At the same time, for places where gas leakage and diffusion may occur, detection mechanisms 20 should also be placed around them. It should be noted that when the portable gas detection device for emergency rescue is moved by a mobile device, in order to facilitate the observation of the position, location, and surrounding environment of the mobile device, the mobile device can be simultaneously equipped with a GPS positioning system, a camera detection system, etc., and connected to the remote control platform together with the detection mechanism 20 and the separation mechanism 30. Specifically, during assembly, multiple detection mechanisms 20 are placed on the clamping assembly 13, and then the connection port 12 fixedly installed on the storage mechanism 10 is connected to the mobile device, and the connection is completed. When the interface 12 is selected, it can be clamped on the mobile device by using a spring clip, a clamp or other devices, or it can be permanently welded on the mobile device by welding or other methods. The mobile device is equipped with a GPS positioning system and moves in the emergency site according to a pre-planned route under the control of the remote control platform. During the movement, the detection body 21 automatically extracts the surrounding air and detects dangerous gases such as carbon monoxide contained in the air, and transmits the detection results to the remote control platform in real time for reference by outside personnel. When the mobile device moves to the pre-selected placement position of the detection mechanism 20, the outside personnel control the separation mechanism 30 through the remote control platform to push the detection mechanism 20 in the clamping component 13 It moves upward until it falls through the opening on the storage mechanism 10. The position of the detection mechanism 20 after falling is determined, and the gas in the ambient air is continuously detected. As the mobile device continues to move, the detection mechanism 20 is eventually dispersed in the rescue site. Outsiders make judgments based on the environmental factors in the rescue site until the rescue environment is met. The rescue personnel carry out rescue operations. During this process, multiple detection mechanisms 20 continuously monitor the gas environment, which is convenient for timely prediction and observation of possible safety hazards such as the diffusion of dangerous gases, excessive concentrations, and explosions, thereby improving the protection of the lives of the rescue personnel. After the rescue is over, the dispersed detection mechanisms 20 are recovered and the power is turned off, and they can be left for use again.

[0051] Example 1

[0052] like Figures 1 to 7 As shown, the portable gas detection device for emergency rescue includes multiple detection mechanisms 20 and a remote control platform. The multiple detection mechanisms 20 are detectors with built-in wireless communication modules. The multiple detection mechanisms 20 and the separation mechanism 30 are wirelessly connected to the remote control platform.

[0053] By setting up multiple detection mechanisms 20, when the mobile device is moving, the detection mechanisms 20 can be dispersed in the rescue space through the cooperation of the separation mechanism 30 and the remote control platform, thereby continuously monitoring the gas environment of the rescue space, providing data reference for outside personnel to evaluate the safety of the rescue space, thereby enhancing the life safety of the rescue personnel. At the same time, during the process of the detection mechanism 20 falling off, the setting of the support component 22 can ensure the safety of the detection body 21 when it is dispersed, and on the premise of ensuring the safety of the detection mechanism 20, it is convenient for the detection body 21 to detect the gas environment.

[0054] like Figure 2 As shown, the arrangement of multiple deployment legs 221 and support legs 223 results in a relatively large space occupied by the detection body 21, the deployment legs 221, and the support legs 223, making it inconvenient for rescue personnel to carry and store them. Therefore, in order to enhance the convenience of storage, on the one hand, the arrangement of the rotating shaft 214 allows the deployment legs 221 and the support legs 223, which are evenly distributed around the detection body 21, to rotate and fit around the detection body 21. On the other hand, the arrangement of the limiting rod 231 can limit the deployment legs 221 after storage, thereby shrinking the space occupied by the support assembly 22. Specifically, the two limiting rods 231 have a yielding arc edge on the side away from each other. The yielding arc edge is arranged at the end of the limiting rod 231, and the bending center of the yielding arc edge on one limiting rod is toward the other limiting rod. During the rotation of the deployment legs 221, the connecting parts 222 between the deployment legs 221 are compressed. At the same time, during the rotation of the deployment legs 221, the deployment legs 221 contact the arc edge of the limit rod 231. When the deployment legs 221 continue to rotate, the limit rod 231 is pushed to contract. Then, when the deployment legs 221 pass over the limit rod 231, the limit rod 231 is reset to limit the deployment legs 221, and finally the overall volume formed by the detection body 21, the deployment legs 221 and the support legs 223 is compressed, so that it is convenient to be stored on the storage mechanism 10.

[0055] like Figure 2As shown, the clamping assembly 13 has two sets of parallel and spaced clamping parts, and each set of clamping parts has two parallel and spaced clamping rods 131 and a clamping groove 132 formed therein. One end of the clamping rod 131 is connected to the end plate 11, and the other end of the clamping rod 131 extends perpendicularly to the end plate 11 in a direction away from the end plate 11. The two sets of clamping parts and the end plate 11 form a "C"-shaped structure with an opening. The clamping groove 132 corresponds to the lifting rod 242. When the detection body 21 is placed on the storage mechanism 10, the lifting rod 242 moves into the clamping groove 132, and the limiting rod 231 is located outside the clamping groove 132. At this time, the lifting spring 241 is in an extended state, and the limiting rod 231 is located on the rotation path of the unfolding leg 221.

[0056] like Figure 2 As shown, when the detection body 21 and the unfolding legs 221 and other structures are stored in the storage mechanism 10, the lifting rod 242 is aligned with the clamping groove 132. Since the clamping groove 132 and the lifting rod 242 are symmetrically arranged, when the detection body 21 is installed on the storage mechanism 10, the lifting spring 241 between the lifting rod 242 and the telescopic groove 213 is in an extended state. At this time, the limiting rod 231 fixed on the lifting rod 242 is located on the rotation path of the unfolding legs 221. The unfolding legs 221 are manually rotated to limit and fold the unfolding legs 221 and the support legs 223, resulting in multiple detection bodies. 21 is installed in the storage mechanism 10, and the separation mechanism 30 includes an electric telescopic rod 31. The output end of the electric telescopic rod 31 extends into the clamping assembly 13. When the electric telescopic rod 31 is started and pushes the detection body 21 to fall off, the restriction of the storage mechanism 10 is lost at this time, and the lifting spring 241 contracts, causing the lifting rod 242 and the limit rod 231 to move toward the detection body 21. As the limit rod 231 continues to move, the limit rod 231 falls off the rotation path of the deployment leg 221. Under the action of the connecting member 222, the deployment leg 221 is deflected, thereby causing the support assembly 22 to be deployed to support and protect the detection body 21.

[0057] like Figure 5 and Figure 6 As shown, the support leg 223 is made of a telescopic rod, and a telescopic bag 226 with a spring is installed in the support leg 223. The air outlet of the air outlet channel 224 extends to the side wall of the unfolding leg 221. A sealing plate 212 is fixedly installed on the detection body 21, and the sealing plate 212 is made of elastic rubber material on the side close to the unfolding leg 221.

[0058] like Figure 5 and Figure 6As shown, when the detection body 21 is placed on the storage mechanism 10, the legs 221 are manually folded and unfolded, and the supporting legs 223 are manually pressed to cause the supporting legs 223 to shrink. During this process, the volume of the telescopic bag 226 is reduced, and the air in the telescopic bag 226 is discharged outward through the air outlet channel 224. Since the other end of the air outlet channel 224 extends to the sealing plate 212 at this time, when the telescopic bag 226 releases air, the sealing plate 212 is deformed under the action of air pressure, causing gas to leak out. When the staff folds and releases the pressure on the supporting legs 223, the telescopic bag 226 has a tendency to increase under the action of the spring inside the telescopic bag 226. The increase of the telescopic bag 226 requires gas to enter. When negative pressure acts on the air outlet channel 2 When the air outlet of the air outlet channel 24 is opened, the sealing plate 212 is deformed toward the air outlet direction of the air outlet channel 224, blocking the air outlet of the air outlet channel 224, thereby making the support leg 223 unable to reset. When the electric telescopic rod pushes the detection body 21 to disengage, the limit rod 231 moves and the deployment leg 221 deflects, causing the air outlet of the air outlet channel 224 to separate from the sealing plate 212. At this time, the gas enters the telescopic bag 226. Under the action of the spring in the telescopic bag 226, the support leg 223 automatically extends, and then cooperates with the deployment leg 221 to support the detection body 21, so as to support and protect the detection body 21 and raise the height of the detection body 21 to avoid the influence of debris on the ground on the gas detection.

[0059] like Figure 5 As shown, multiple air ducts 25 are installed on the detection body 21. The air ducts 25 extend at multiple angles around the detection body 21. By installing and extending the air ducts 25 around the detection body 21, air is drawn from all sides of the detection body 21 during air extraction testing, thereby expanding the detection range and reducing detection errors.

[0060] like Figure 5 As shown, each of the deployment legs 221 is provided with a mounting slot 227, into which the air duct 25 extends, and then through the mounting slot 227 to the support leg 223. Extending the air duct 25 to the mounting slot 227 and the support leg 223, and utilizing the contraction and deflection of the deployment legs 221 and the support leg 223, reduces the space occupied when stored, enhancing storage convenience. When gas detection is being performed, the deflection and extension of the deployment legs 221 and the support leg 223 cause the air duct 25 to be more evenly dispersed, thereby enhancing the uniformity of air extraction from the space.
