Seabed gas leakage detection simulation device

Abstract

The invention relates to the field of seabed observation, in particular to a seabed gas leakage detection simulation device. It includes a shell, a shooting mechanism, a multi-beam echo detection mechanism, a bubble generator and a gas distribution mechanism. The shell includes a front wall, a side wall and a rear wall. Watertight fixed connection, the bottom of the front wall, side wall and rear wall are all watertight and fixedly connected with the bottom plate, the middle part of the front wall is provided with an inner recess, the outer side of the inner recess is provided with a shooting mechanism, and the outer side of the front wall is provided with In the multi-beam echo detection mechanism, a bubble generator is arranged on the bottom plate, and the bubble generator is connected with the gas distribution mechanism. It realizes the simulation of the escape process of different gases on the seabed, and can simulate different bubble numbers and bubble velocities. The utility model has the advantages of simple structure, convenient use and low cost.

Description

technical field [0001] The invention relates to the field of seabed observation, in particular to a seabed gas leakage detection simulation device. Background technique [0002] The amount of methane leaked from seabed cold seep natural gas into ocean water and the atmosphere is very alarming. Since methane is a greenhouse gas, such a huge amount of methane release is an important factor affecting global climate change. Due to the great impact of gas release from submarine cold seeps on the global environment, research on natural gas seepage from submarine cold seeps continues to advance. At present, in-situ flow online measurement devices have appeared in China, but the measurement environment of in-situ measurement has high requirements, and there are many restrictions on the materials and power consumption of the equipment, the actual value that can be generated is small, and the working performance and stability need to be improved. , and limited by existing technical c...
