It plays an important role in the development of the national economy and is one of the pillar industries in my country. Petrochemical industry refers to the processing industry that uses petroleum and natural gas as raw materials to produce petroleum products and petrochemical products. Petroleum products are also called oil products, mainly including various fuel oils (gasoline, kerosene, diesel, etc.) and lubricating oils as well as liquefied petroleum gas, petroleum coke, paraffin, asphalt, etc. In China, the patent announcement number CN217717673U discloses a safety inspection device for petrochemical industry, including an upper fixed ring, a lower fixed ring and a detector. The backs of the upper fixed ring and the lower fixed ring are rotatably connected by hinges. The inner walls of the fixed ring and the lower fixed ring are both provided with T-slots, and two arc blocks are slidably connected to the left and right sides of the T-slot, and a fixed box is arranged between the two arc blocks. The utility model is a safety inspection device for petrochemical industry, in which the upper fixed ring and the lower fixed ring are sleeved on the petroleum or chemical pipeline, and the driving component drives the moving wheel to rotate along the inner wall of the T-slot. Since the T-slot forms a circular ring shape, the fixed box drives the detector to perform circumferential detection along the outer surface of the pipeline, thereby avoiding the need to climb back and forth to the front and back sides of the petrochemical pipeline during inspection, and the need to bend down frequently when performing bottom inspection, which is not only inconvenient for inspection, but also has the problem of low inspection efficiency.

[0003] In the above technical solution, a safety inspection device for petrochemical industry requires workers to manually hold the handles tightly to fix the upper fixing ring and the lower fixing ring on the petrochemical pipeline in use, so as to perform a circumferential inspection on the pipeline. In addition, the inspectors need to observe the movement trajectory of the detector with their bodies sideways to facilitate timely discovery of abnormal locations of pipeline inspections, which increases the work intensity of the inspectors and causes excessive physical exhaustion.

[0004] Therefore, a petrochemical safety inspection device is proposed. Utility Model Content
