[0034] In order to make the purpose, technical solutions and advantages of this specification more clear, this specification is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0035] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of this specification should be understood by people with ordinary skills in the field to which the present disclosure belongs.

"Connect" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0036] As described in the background technology section, there is a possibility of sudden accidents when a high-speed train travels in a low-vacuum pipeline, such as vehicle failure, suspension system failure, train collision, pipeline depressurization, fire, etc. When an accident occurs in a high-speed train, it will inevitably affect the environment inside the pipeline and release a large amount of harmful gases or high-temperature gases. However, there is no heat convection or it is weak in the pipeline, and the heat of the high-temperature toxic flue gas is difficult to dissipate. If the discharge of a large amount of toxic gases or high-temperature air cannot be removed in time, it is likely to pose a threat to the safety of the pipeline.

[0037] In view of the above-mentioned actual situation, one or more embodiments of the present specification propose a pipeline gas treatment device which senses the position of harmful gas through a harmful gas sensing component, isolates it through a separation wall, and opens the air intake in the corresponding direction through the gas treatment component to perform targeted gas treatment, thereby quickly treating the harmful gas in the closed pipeline, accelerating the control and elimination of the harmful gas, and thus ensuring the safety of people or materials.

[0038] like Figure 1 , Figure 2 , Figure 3 FIG. 1 is a schematic diagram of a pipeline gas processing device provided in one or more embodiments of the present specification, which is applied to at least one segmented pipeline 100 and includes:

[0039] At least two harmful gas sensing components 110 are evenly arranged on the top of the segmented pipeline 100;

[0040] A separation wall 120 is provided at the connection between the segmented pipelines 100;

[0041] The gas processing component 130 is arranged on the outer side of the top center of the segmented pipeline 100, and is provided with at least one air intake port 131 on the side facing the segmented pipeline 100. The gas processing component 130 is configured to be able to extend into the segmented pipeline 100, and after extending into the segmented pipeline, it can open the air intake port 131 in the corresponding direction according to the feedback of the harmful gas sensing component 110 to process the gas in the segmented pipeline 100.

[0042] Among them, segmented pipelines are generally used for track settings of subways, high-speed trains, etc. The tracks of subways and high-speed trains are laid in tunnels spliced ​​by multiple segmented pipelines. When an accident occurs to a moving train or an accident occurs in the pipeline due to unspecified factors, it is likely to be accompanied by the generation of a large amount of harmful gas or high-temperature gas. Therefore, the harmful gas sensing component set on the top of the segmented pipeline will sense the generation of harmful gas at the first time. Here, multiple harmful gas sensing components can be set on the top of the pipeline, evenly distributed at various places on the top of the pipeline, so that the harmful gas sensing component can accurately detect within the coverage range.

[0043] Afterwards, the location of the accident pipeline can be determined through the feedback of the harmful gas sensing component, so that the isolation wall located at the connection between the two ends of the accident pipeline and other segmented pipelines can be opened, and then the accident pipeline can be isolated by the isolation wall to prevent the spread of harmful gases. Here, the isolation wall itself can be a folding isolation wall, which is separated by unfolding, or it can be a solid isolation wall, which is separated by translational movement. Under normal conditions, the isolation wall is hidden in the segmented pipeline so as not to affect the operation of the train in the segmented pipeline.

[0044] Afterwards, the gas processing component can generally be set on the outside of the segmented pipeline under normal conditions, and will not affect the operation of the train in the segmented pipeline. When the harmful gas sensing component senses harmful gas, the gas processing component will extend into the segmented pipeline. Since the gas processing component is set at the center of the top of the segmented pipeline, the evenly distributed harmful gas sensing components have a directional concept relative to the gas processing component. After the gas processing component is extended, the air intake port in the corresponding direction can be opened according to the feedback of the harmful gas sensing component. If multiple harmful gas sensing components provide feedback, multiple air intake ports can be opened to extract gas from the pipeline. In some application scenarios, if the disaster occurs just below the gas processing component, the gas processing component can also be provided with a sensing unit and an air intake port facing the bottom of the segmented pipeline on the side facing the bottom of the segmented pipeline. If the sensing unit senses harmful gas, the air intake port is directly opened for inhalation. At the same time, in some application scenarios, such as underground or in specific scenarios, the inhaled gas cannot be discharged immediately, so a purification unit and a cooling unit can be integrated into the gas processing component to purify and cool the inhaled gas immediately, thereby eliminating the hazards of these gases.

[0045] From the above description, it can be seen that a pipeline gas processing device provided by one or more embodiments of this specification is applied to at least one segmented pipeline, including: at least two harmful gas sensing components, evenly arranged on the top of the segmented pipeline; a partition wall, arranged at the connection between the segmented pipelines; a gas processing component, arranged on the outer side of the center of the top of the segmented pipeline, and at least one air intake port is arranged on the side facing the segmented pipeline, and is configured to be able to extend into the segmented pipeline, and after extending into the segmented pipeline, it can open the air intake port in the corresponding direction according to the feedback of the harmful gas sensing component to process the gas in the segmented pipeline. One or more embodiments of this specification sense the direction of the harmful gas through the harmful gas sensing component, isolate it through the partition wall, and open the air intake port in the corresponding direction through the gas processing component to carry out targeted gas processing, so that the harmful gas in the closed pipeline can be quickly processed, the control and elimination of the harmful gas can be accelerated, and the safety of people or materials can be ensured.

[0046] In some application scenarios, such as Figure 2 and Figure 3 As shown, the gas processing assembly 130 further includes: a negative pressure air suction cooling body 132, an extension assembly 133, a guide rail 134 and a limit block 135;

[0047] The extension component 133 is disposed in the negative pressure air suction cooling body 132, is connected to the air intake port 131, and is configured to be able to perform an extension reciprocating motion so that the air intake port 131 can extend into the segmented pipeline 100;

[0048] The guide rail 134 is arranged on the negative pressure air suction cooling body 132;

[0049] The limit block 135 is disposed on the guide rail 134 and connected to the extension component 133. It is configured to be able to reciprocate on the guide rail 134 following the extension of the extension component 133, and to form structural interference with both ends of the guide rail 134 to limit the extension range of the extension component 133.

[0050] Among them, the negative pressure suction cooling body is used to absorb the gas in the segmented pipeline by establishing a negative pressure. Here, in some specific embodiments, in the pipeline of the high-speed train, although it is a high vacuum state under normal conditions, after a disaster occurs, the smoke and the like generated will fill the entire space so that the vacuum state in the pipeline is lost, and then the gas can be absorbed by the negative pressure suction method. At the same time, the small closed space established by the isolation wall will quickly reduce the air in the closed space after suction, so that the further expansion of most disasters can be controlled. Afterwards, the extension component can be a flexible foldable material, etc., which cooperates with the guide rail and the limit block to enable it to be freely extended and folded within a certain range. Of course, the limiting method of the extension component can also be realized by setting a baffle at the top of the segmented pipeline, and the baffle blocks the continued extension of the extension component to limit the distance of the air inlet. In addition, here, by extending the air inlet, the air inlet can be closer to the disaster occurrence point, which is more conducive to disaster control.

[0051] In some application scenarios, in order to deal with the situation where the disaster location is directly below the gas processing component. Figures 1 to 4 As shown, a harmful gas sensing unit 137 is provided on the side of the gas processing component 130 facing the bottom of the segmented pipeline 100, and the harmful gas sensing unit 137 is configured to open the air intake port 131 of the gas processing component 130 facing the bottom of the segmented pipeline 100 when harmful gas is detected.

[0052] The harmful gas sensing unit may include a sensing accessory for toxic gas and a sensing accessory for temperature, so as to simultaneously monitor the toxic gas and temperature directly below the gas processing component. In addition, a lighting lamp for illumination may be provided next to the air intake.

[0053] In some application scenarios, in order to process the gas immediately after it is inhaled, to prevent pollution and secondary disasters, etc. Figure 2 As shown, the gas processing assembly 130 further includes:

[0054] The purification component 136 is configured to purify the inhaled gas.

[0055] Among them, the purification component will mainly purify, filter or collect specific gases with greater hazards, and directly discharge or compress more conventional gases.

[0056] In some application scenarios, in order to provide clear early warning and escape warning, the gas processing assembly is provided with an alarm light and an alarm speaker.

[0057] When a disaster occurs, the gas processing component will flash the alarm light and sound the alarm speaker as soon as it receives feedback from the harmful gas sensing component, so as to warn the passengers in the train in the pipeline. The alarm light and the alarm speaker can be in any suitable form and can be located anywhere in the gas processing component as long as they can play the corresponding role.

[0058] In some application scenarios, in order to carry out targeted measurements of various disaster indicators such as toxic gases and temperature. Figure 1 As shown, the harmful gas sensing component 110 includes: a toxic gas sensing unit 111 and a temperature sensing unit 112 .

[0059] Among them, dedicated sensing devices can also be set up according to specific application scenarios to make the determination of disasters more accurate.

[0060] In some application scenarios, in order to enable passengers or escape devices carrying passengers or cargo to smoothly escape from the segmented pipeline in an accident. Figure 1 As shown, an escape door 121 may be provided on the isolation wall 120 .

[0061] Among them, the escape door can be opened and closed automatically or manually, and its material itself is similar to that of the isolation wall, which plays a fire-proof isolation effect.

[0062] In some application scenarios, in order to determine the length or range of the accident train, the isolation wall that needs to be opened is determined. Figure 1 As shown, the device further includes:

[0063] The train sensing component 140 is disposed on the side wall of the segmented pipe 100 and is configured to determine the position of the train in the segmented pipe 100, so as to determine the isolation wall 120 that needs to be activated.

[0064] Among them, due to the different lengths of trains, when they stop, they may not occupy only one segmented pipe, so the specific length of the train sensing component is needed to determine the number of segmented pipes occupied by the train, and then open the isolation walls in front and behind the train. The train sensing component can be an infrared sensing device, which determines the approximate length of the train or the approximate stopping range by determining whether there are obstacles blocking it.

[0065] In some application scenarios, lighting is provided to help passengers escape. Figure 1 As shown, the device further includes: an emergency light strip 150 arranged on the side wall of the segmented pipeline 100.

[0066] Based on the same inventive concept, one or more embodiments of this specification also provide a pipeline gas processing method, such as Figure 5As shown, including:

[0067] Step 501: When the harmful gas sensing component detects the presence of harmful gas in the segmented pipeline, the isolation wall is activated to isolate the segmented pipeline.

[0068] Step 502: After the isolation wall completes isolation, the air intake of the gas processing component is extended into the segmented pipeline.

[0069] Step 503: the gas processing component opens the air intake port in the corresponding direction according to the feedback from the harmful gas sensing component to process the gas in the segmented pipeline.

[0070] The method of the above embodiment is applied to the corresponding pipeline gas processing device in the above embodiment. The description of the specific contents of the above steps and the corresponding beneficial effects have been involved in the embodiment of the above pipeline gas processing device, so they will not be repeated in this embodiment.
