[0037] Considering that coal mine safety has always been an important issue in the production process of the coal industry, gas is the number one killer of coal mine safety, and the proportion of gas accidents in outburst coal mines exceeds 60% of all gas accidents. The main measure for controlling gas in coal mines is extraction, that is, to extract gas from the coal mine in advance. During the gas extraction process, it is necessary to detect the pipeline gas in each extraction pipeline, specifically to detect the flow rate, negative pressure, etc. of the gas in multiple pipelines.

[0038] Currently, the pipeline gas in multiple pipelines is mainly detected manually. However, when detecting pipeline gas manually, the labor cost required is relatively high, the operation is relatively complex, the inspection frequency and accuracy are low, and it is difficult to overcome the problem of data falsification.

[0039] Based on this, an embodiment of the present application provides a multi-pipeline gas detection system, including: a pitot tube, a solenoid valve group, and a detection module; an external pipeline to be inspected is connected to the pitot tube, the pitot tube is connected to two inlets of the solenoid valve group through its two air inlets, and is connected to the detection module through two outlets of the solenoid valve group; the pitot tube is used to transfer the pipeline gas of the pipeline to be inspected to the two inlets of the solenoid valve group; the solenoid valve group is used to control the pipeline gas of the pipeline to be inspected corresponding to the solenoid valve group to be transferred to the detection module; the detection module is used to perform gas detection on the inflowing pipeline gas to obtain gas detection information of the pipeline gas.

[0040] Please refer to Figure 1 , Figure 1 which shows a schematic structural diagram of the multi-pipeline gas detection system described in the embodiment of the present application; specifically, as Figure 1 shown, the multi-pipeline gas detection system 100 includes: a pitot tube 1, a solenoid valve group 2, and a detection module 3.

Among them, the solenoid valve group 2 is a two-inlet and two-outlet solenoid valve group.

[0041] It should be noted that by using a two-inlet and two-outlet solenoid valve group, compared with a single-inlet and single-outlet solenoid valve group 2, the number of solenoid valves used is reduced, the volume of the detection system is reduced, the cost is lowered, and it is easier to maintain.

[0042] The pitot tube 1 is used to transfer the pipeline gas of the pipeline to be inspected to the two inlets of the solenoid valve group 2.

[0043] The solenoid valve group 2 is used to control the pipeline gas of the pipeline to be inspected corresponding to the solenoid valve group 2 to be transferred to the detection module 3; different solenoid valve groups 2 control different pipelines to be inspected. Among them, different solenoid valve groups 2 control different pipelines to be inspected, that is, one solenoid valve group 2 controls one pipeline to be inspected. For example, the 1st pipeline to be inspected corresponds to the 1st solenoid valve group 2, that is, the 1st pipeline to be inspected is controlled by the 1st solenoid valve group 2.

In the present application, the pipeline gas of the inspected pipeline is transferred to the solenoid valve group through the pitot tube, and the pipeline gas is controlled to be introduced into the detection module through the solenoid valve group for detection, realizing the systematic detection of the pipeline gas, reducing the labor cost, simplifying the detection operation, improving the inspection frequency and accuracy, and at the same time solving the problem of data fraud.

[0047] Further, as Figure 2 shown, the detection module 3 includes a flow rate module 31, a negative pressure module 32, and a concentration module 33; two outlets of the solenoid valve group 2 are connected to the flow rate module 31 and the negative pressure module 32.

[0048] Among them, the flow rate module 31 is used to detect the flow rate information of the pipeline gas.

[0049] The negative pressure module 32 is used to detect the negative pressure information of the pipeline gas.

[0050] Further, as Figure 2 shown, the detection module 3 further includes a concentration module 33; the negative pressure module 32 is connected to the concentration module 33.

[0051] The concentration module 33 is used to detect the composition and concentration of the pipeline gas.

[0052] Further, the detection module 3 further includes an air extraction pump; the air extraction pump is connected to the concentration module 33.

[0053] Among them, the air extraction pump is used to extract the pipeline gas from the negative pressure module 32 into the concentration module 33 to detect the composition and concentration of the pipeline gas in the concentration module 33.

[0054] Further, the multi-pipeline gas detection system further includes a gas compression pump; the gas compression pump is connected to the concentration module 33.

[0055] A compressor pump is used to input the gas in the surrounding environment into the solenoid valve group 2 to reduce the interference of external factors. Thus, the error of gas detection can be reduced.

[0056] Furthermore, the multi-pipeline gas detection system further includes a control module; the control module is respectively connected to the solenoid valve group 2, the detection module 3, and the compressor pump.

[0057] The control module is used to control the solenoid valve group 2, the detection module 3, and the compressor pump.

[0063] The display module is used to display according to the received display commands.

[0064] Furthermore, Figure 3 is the actual structure diagram of the multi-pipeline gas detection system. As Figure 3 shown, there are n pipelines to be inspected. Taking one of the pipelines to be inspected as an example, the pitot tube 1, two-in-two-out solenoid valve group, flow rate module, negative pressure module, concentration module, air extraction pump, compressor pump, startup control module, CPU control, and display module in the figure represent the pitot tube 1, solenoid valve group 2, flow rate module, negative pressure module, concentration module, air extraction pump, compressor pump, startup module, central processing unit, and display module of the present application. Through Figure 3 the connection of each device in, it can be used as the implementation of the multi-pipeline gas detection system of the present application.

[0065] For example, the central processing unit gives the command corresponding to the No. 1 solenoid valve group according to the process setting. At this time, the two passages of the solenoid valve group are opened, and the pipeline to be inspected is connected to the flow rate module and the negative pressure module to detect the flow rate information and negative pressure information. Then, the air extraction pump is started to extract air, and the pipeline gas is pumped to the concentration module to detect the gas and concentration. Next, the air pressure pump closes the No. 1 solenoid valve to end the detection of the No. 1 pipeline to be inspected, and then starts the No. 2, 3,..., n solenoid valves in turn to complete the detection of the No. 2, 3,..., n pipelines to be inspected, thus completing the gas detection of n pipelines to be inspected.

[0066] Those skilled in the art can clearly understand that for the convenience and conciseness of description, the devices described above can be implemented in other ways. The device embodiments described above are merely illustrative. For example, the division of the mechanisms is only a logical function division, and there can be other division methods in actual implementation.

[0067] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
