[0002] A chemical plant is a factory engaged in the chemical industry. With the rapid development of China's economy, the prices of China's chemical products are also rising. The chemical industry can be divided into three categories: petrochemicals, basic chemicals, and chemical fibers. Most chemical plants have a large number of pipelines, which are large in size. The pipelines can be used to transport flammable gases. In order to prevent flammable gas leaks and avoid danger, chemical plants will have specialized technicians to regularly inspect the pipelines to prevent large-scale leakage of flammable gases.

[0003] However, manual inspection of pipelines for flammable gas leaks may result in missed detections when gas leaks occur, and flammable gas leaks cannot be discovered immediately, resulting in low safety. Existing gas detection devices are relatively fixed in position and are often installed at pipeline connections, making it difficult to inspect the entire pipeline, thus affecting the inspection effect. For example, a chemical safety gas detection device disclosed in the patent document with authorization announcement number CN214306558U3 also has this problem.

[0004] Therefore, it is necessary to provide a new chemical safety gas detection device to solve the above technical problems. Utility Model Content

[0015] 1. The upper and lower fixing rings are combined and sleeved on the outside of the chemical gas pipeline to ensure that the device is firmly fixed on the pipeline, and the setting of the electric telescopic rod gives the device the ability to adjust in the vertical direction, so that it can adapt to pipelines of different diameters, improving the versatility of the device. The combined design of the box, the rotating shaft and the moving wheel enables the device to move freely on the chemical gas pipeline.

The cooperation of the fixing bolts and nuts can make the installation and disassembly of the device simple and quick. When installing, you only need to pass the fixing bolts through the fixing plate and tighten the nuts; when disassembling, you only need to loosen the nuts and remove the fixing bolts, which greatly improves the convenience of maintenance. Gas leakage can be reduced by closing the electric valve. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] It is worth noting that the circuits, electronic components and modules involved in the present invention are all existing technologies and can be fully implemented by those skilled in the art. Needless to say, the content protected by the present invention does not involve improvements to software and methods.

[0033] The working principle of the chemical safety gas detection device provided by the utility model is as follows:

[0034] This solution also includes an electric control cabinet, which is installed on the equipment. When in use, each electrical device can be started and operated through the electric control cabinet. The power connection method of each electrical device is an existing mature technology and is well known to people in this field, so it will not be described in detail here.

[0035] When in use, first, the upper fixing ring 2 and the lower fixing ring 3 are combined and sleeved outside the chemical gas pipeline 1, and the upper fixing ring 2 and the lower fixing ring 3 are fixed with fixing bolts, and the electric telescopic rod 4 is turned on. The output rod of the electric telescopic rod 4 is extended to make the moving wheel 7 contact the outer wall of the chemical gas pipeline 1, and the upper protective shell 12 and the lower protective shell 13 are combined and sleeved outside the upper fixing ring 2 and the lower fixing ring 3, and then the first cover plate 16 and the second cover plate 17 are respectively pasted on the upper protective shell 12 and the lower protective shell 13, so as to protect the detection environment. When a more comprehensive detection of the chemical gas pipeline 1 is required, the motor 8 is turned on. With the cooperation of the two bevel gears 9, the motor 8 drives the rotating shaft 6 to rotate, thereby driving the moving wheel 7 to rotate. At this time, the device moves, and the gas detector 15 is used to detect the chemical gas concentration in the internal space of the upper protective shell 12 and the lower protective shell 13. When the concentration is high, an alarm is issued to remind the staff to deal with it in time. At the same time, when the gas concentration is high, the fan 18 is turned on. The fan 18 can extract the chemical gas to prevent the chemical gas concentration from being too high and causing danger.

[0036] Compared with related technologies, the chemical safety gas detection device provided by the present invention has the following beneficial effects:

[0037] The utility model provides a gas detection device for chemical safety. The upper fixing ring 2 and the lower fixing ring 3 are combined and sleeved on the outside of the chemical gas pipeline 1 to ensure that the device is firmly fixed on the pipeline. The setting of the electric telescopic rod 4 gives the device the ability to adjust in the vertical direction, so that it can adapt to pipelines of different diameters, improving the versatility of the device. The combined design of the box 5, the rotating shaft 6 and the moving wheel 7 enables the device to move freely on the chemical gas pipeline 1. When it is necessary to detect different positions of the pipeline, it is only necessary to adjust the position of the device through the driving component and then use the moving wheel 7 to roll on the outer wall of the pipeline to achieve comprehensive detection coverage. The cover effectively avoids the phenomenon of missed detection. The power transmission between the output shaft of the motor 8 and the rotating shaft 6 is realized by the bevel gear 9, which makes the device structure more compact and improves the transmission efficiency. The rotation of the rotating shaft 6 is driven by the motor 8 to drive the moving wheel 7 to rotate, so that the device can be moved on the chemical gas pipeline 1 by itself. There is no need to manually move the device to detect gas leakage, which is more labor-saving. The upper protective shell 12 and the lower protective shell 13 are bonded together by waterproof glue to form a closed protective space, which protects the key components of the device and prevents the leaked chemical gas from escaping directly. 3, respectively, pasting the first cover plate 16 and the second cover plate 17 on the upper and lower protective shells 12 and 13 can further enhance the protection effect. The gas detector 15 can monitor the concentration of combustible gas inside the device in real time, so that the staff can find potential leakage risks in time, which provides an important basis for taking safety measures in time. The combustible gas detected can be discharged from the outside of the device in time through the exhaust component to prevent the accumulation of combustible gas inside the device, thereby reducing the risk of dangerous events such as explosion or fire. The cooperation of the limit block 11 and the limit plate 14 can ensure that the upper protective shell 12 and the lower protective shell 13 can be fixed to the upper fixing ring 2 and the lower fixing ring 3. Maintaining the correct position without offset or rotation helps to improve the overall stability and reliability of the device. Through the suction effect of the fan 18 and the air inlet pipe 19, the flammable gas inside the device can be quickly discharged through the air inlet pipe 19, avoiding the accumulation of gas inside the device, thereby reducing potential safety risks. The installation and disassembly of the device can be simple and quick through the combination of fixing bolts and nuts. When installing, only the fixing bolts need to be passed through the fixing plate and the nuts need to be tightened; when disassembling, only the nuts need to be loosened and the fixing bolts need to be removed, which greatly improves the convenience of maintenance. Gas leakage can be reduced by closing the electric valve 20.
