Problems solved by technology

At the same time, there is a lack of suitable test benches in the existing technology to simulate the working stress under different conditions of flood impact, and most of them do not take into account that the actual flood water contains impurities such as sand and stones that move at nearly constant speed, and the simulation is not accurate.
In addition, in the simulation experiments of the prior art, the fluid being transported in the pipeline 7 is mostly neglected, and the simulation is not complete enough.

Abstract

The invention discloses a multi-span crossing river oil pipeline mechanical experiment device for internal and external flow, which comprises a support platform, a high-level water tank and an arc-shaped track are arranged on the support platform, a water pool is arranged on the right side of the support platform, and a high-level water tank is arranged on the support platform. There is a water outlet on the top, the left end of the track is located directly below the water outlet, the right end of the track is located in the inner cavity of the pool, a bracket is arranged in the pool, a pipe is installed on the bracket, and a strain gauge is provided on the pipe. The invention takes into account the sediment, stones contained in the flood and the movement of the fluid in the pipeline, and can carry out simulation tests on pipelines with different degrees of exposure and similar "multi-span beams".

Description

technical field [0001] The invention relates to the design of an oil pipeline, in particular to a mechanical experiment device for a multi-span oil pipeline crossing a river for internal and external flow. Background technique [0002] The oil pipeline is an important part of the national lifeline project and the main artery of the country's energy. Its safe operation has a great impact on the country's economic development. Due to the influence of various reasons, the existing pipeline design codes have deficiencies in the design of pipelines crossing rivers, and it is necessary to carry out systematic research on this issue, among which experimental research is an important aspect, and the experimental bench is the guarantee for carrying out experimental research . However, in the actual problem of large-scale crossing pipelines, the flow velocity of the flood and the degree of exposure of the pipeline are not constant, especially for the experimental testing of pipelines...
