[0002] Chemical process, also known as chemical technology or chemical production technology, refers to the method and process of converting raw materials into products mainly through chemical reactions, including all measures to achieve this transformation. Chemical production technology is usually proposed for certain products or raw materials, such as the production of vinyl chloride, synthesis of methanol, production of sulfuric acid, coal gasification, etc.

[0003] When inspecting the chemical process pipeline, the chemical process gas in the air is only detected by a handheld detector, which can only detect the leakage range but cannot accurately know the leakage location, thereby failing to meet the use requirements. Therefore, it is necessary to propose a device for detecting chemical process gas leakage. Utility Model Content

[0006] Preferably, a threaded groove is provided on each of the two mounting blocks, a threaded hole is provided through the groove wall of each of the two mounting grooves, and two bolts are threadedly connected to the two threaded grooves and the two threaded holes.

[0007] Preferably, the fixing ring is arranged in a semi-ring shape, and the upper end of the fixing ring abuts against the inner wall of the installation frame.

[0008] Preferably, the lower end of the driving wheel passes through the driving groove and the annular groove and extends to the outside of the inner wall of the installation frame.

[0009] Preferably, the fixing ring and the top end of the mounting frame together form an annular block.

[0010] Compared with the prior art, the beneficial effect of the utility model is: when in use, the mounting block is placed on the pipeline, and then the fixing ring is installed on the mounting block and the pipeline is covered. At this time, the motor is started to drive the driving wheel to rotate, and the driving wheel drives the entire equipment to move on the pipeline by rolling on the pipeline. When the pipeline leaks, the chemical process gas will gather in the annular groove and the concentration will increase rapidly, so that the detector can quickly and accurately perform detection, making the overall detection simpler, more convenient and accurate.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-3 The utility model provides a technical solution: a device for detecting chemical process gas leakage, comprising a mounting frame 1, wherein two mounting grooves 2 are provided at the lower end of the mounting frame 1, a mounting block 3 is slidably connected in each of the two mounting grooves 2, a fixing ring 4 is fixedly connected to the two mounting blocks 3, an annular groove 5 is provided between the fixing ring 4 and the mounting frame 1, a driving groove 6 is provided on the upper end groove wall of the annular groove 5, a driving motor 7 is fixedly installed on the groove wall of the driving groove 6, a driving wheel 8 is fixedly connected to the output end of the driving motor 7 through a coupling, and two detectors 9 are fixedly installed on the groove wall of the annular groove 5.

[0017] Among them, a thread groove 10 is opened on each of the two mounting blocks 3, and a threaded hole 11 is opened through the groove wall of each of the two mounting grooves 2. Two bolts 12 are threadedly connected in the two thread grooves 10 and the two threaded holes 11. The bolts 12 are threadedly connected to the thread grooves 10 and the threaded holes 11, so as to fix the mounting block 1 and the fixing ring 4 and make it cover the outside of the pipe.

[0018] The fixing ring 4 is semi-circular in shape, and the upper end of the fixing ring 4 abuts against the inner wall of the mounting frame 1 . The fixing ring 4 and the top of the mounting frame 1 together form an annular block, so that it is convenient to cover the outside of the pipeline.

[0019] The lower end of the driving wheel 8 passes through the driving groove 6 and the annular groove 5 and extends to the outside of the inner wall of the installation frame 1 , so that the driving wheel 8 extends to the outside of the annular groove 5 and abuts against the outside of the pipe.

[0020] Specifically, when using the utility model, firstly, the mounting frame 1 is clamped on the pipeline, and then the mounting block 3 is inserted into the mounting groove 2 until the fixing ring 4 is against the top of the mounting frame 1. At this time, the bolt 12 can be threadedly connected with the threaded groove 10 and the threaded hole 11, so as to fix the mounting block 1 and the fixing ring 4 and make it cover the outside of the pipeline. At this time, the drive motor 7 can be started, and the drive motor 7 will drive the drive wheel 8 to rotate. The drive wheel 8 drives the entire device to move on the pipeline by rolling on the pipeline. When the pipeline leaks and the equipment passes by, the chemical process gas will enter the annular groove 5 and the concentration will rise rapidly in the narrow space.
