Novel water tunnel experiment system for simulating real marine environment

Abstract

The invention discloses a novel water tunnel experiment system for simulating a real marine environment. A guide rail is paved on a closed space foundation, a high-pressure water storage tank and a water storage cabin are built in, and the high-pressure water storage tank is connected with a high-pressure water pump station; an elbow pipeline, a stable pipeline, a shrinkage pipeline, a test pipeline and a diffusion pipeline are connected between a water outlet of the high-pressure water storage tank and a water inlet of the water storage cabin, a reflux pipeline is connected between the waterinlet of the high-pressure water storage tank and the water outlet of the water storage cabin, and the reflux pipeline is provided with a salinity adjustment subsystem; a moving device is arranged atthe bottom of the test pipeline, high-pressure valves and telescopic devices are arranged at both ends, motors are arranged on outer walls of the both ends, telescopic shafts of the motors are connected with the high-pressure valves at the located ends, and a cantilever guide rail is arranged in the test pipeline; and the test pipeline and the water storage cabin are provided with unloading drainage devices. The novel water tunnel experiment system disclosed by the invention simulates the real deep sea environment in terms of pressure, temperature, salinity and ocean current as much as possible, and can complete the key technical index test of deep sea equipment accurately, efficiently and reliably.

Description

technical field [0001] The invention belongs to the field of mechanical design, and more specifically relates to a novel water tunnel experiment system for simulating a real marine environment. Background technique [0002] With the continuous in-depth exploration and exploitation of marine resources and energy, marine equipment, especially deep-sea equipment, has become the focus of equipment manufacturing industries around the world. The deep sea environment is a harsh environment with low temperature, high pressure and strong corrosiveness, which puts forward strict and demanding requirements for the equipment in it. If the equipment wants to survive, experiment and work in the deep sea environment stably, continuously and reliably, the following five conditions must be met: first, the equipment has good sealing performance; second, the equipment has sufficient strength and rigidity; third, the equipment has good corrosion resistance. The fourth is that the equipment car...

However, these two types of equipment have high test costs and long test cycles. The performance of a certain aspect of the equipment is tested separately, and the coupling relationship between different performances is ignored. At the same time, the influence of salinity on the test is also ignored, so that the test cannot completely simulate the real test. deep sea environment
