Problems solved by technology

[0003] Existing applications in structural response and safety evaluation experiments under explosive loads often directly connect the experimental device to the experimental oil and gas pipeline, which causes the problem of coupling between the deformation of the experimental oil and gas pipeline and the deformation of the experimental device when the explosive load is applied , so that the impact of the blast load on the experimental oil and gas pipeline cannot be independently measured, and the impact of the blast load on the support cannot be alleviated

Abstract

The invention discloses a hinged buffer self-anchored buried oil and gas pipeline static explosion experiment device, and belongs to the technical field of oil and gas pipeline experiment equipment. The hinged buffer self-anchored buried oil and gas pipeline static explosion experiment device comprises channel steel provided with a plurality of mounting holes; a plurality of adjustable ground anchor mechanisms, wherein each adjustable ground anchor mechanism passes through different mounting holes to fix the channel steel on the experimental ground; two spherical hinge spring supports which are fixedly connected to the two ends of the channel steel correspondingly, wherein each spherical hinge spring support comprises a base body, a clamping ring and a plurality of springs; a plurality of pressure sensors which are uniformly distributed on the explosion-back surface of the outer wall of an experimental oil and gas pipeline; an acceleration sensor which is arranged on the explosion-back surface of the outer wall of the experimental oil and gas pipeline; and a data processor. According to the hinged buffer self-anchored buried oil and gas pipeline static explosion experimental device, soft contact between the experimental oil and gas pipeline and the seat body and the clamping ring is ensured, so that the independence of deformation of the experimental oil and gas pipeline is ensured, and the spherical hinge spring support ensures the non-coupling property of deformation of the experimental oil and gas pipeline.

Description

technical field [0001] The invention relates to the technical field of oil and gas pipeline experimental equipment, in particular to a hinged buffer self-anchored buried oil and gas pipeline static explosion experimental device. Background technique [0002] Oil and gas resources are important strategic materials of the country and also support the development of the national economy. As one of the five major transportation methods, pipeline transportation has the characteristics of low cost, high safety factor, and high transmission efficiency. Therefore, pipeline transportation is widely used in two-thirds of the world's oil and gas transportation. In recent years, accidental explosions have occurred frequently all over the world. Coupled with the impact of artificial blasting construction, explosive loads have become one of the main threats to buried oil and gas pipelines being damaged by third parties. The safety evaluation experiments of buried oil and gas pipelines und...
