Problems solved by technology

[0004] The pressure resistance performance test of deep-sea composite buoyancy materials basically relies on high-pressure vessels, but due to the airtightness and isolation limitations of high-pressure vessels, it is impossible to capture the destruction moment of buoyancy materials under high hydrostatic pressure in real time. The damage is also unknown, and the performance of the composite material can only be judged by opening the high-pressure vessel after decompression. Therefore, the traditional detection method has low practical efficiency due to the need to open and seal the high-pressure vessel repeatedly. Low precision, high cost, long cycle, low reliability, and difficult to capture the moment of destruction

Abstract

The invention discloses a hydrostatic pressure damage detection device and detection method for a full-sea-depth buoyancy material. The hydrostatic pressure damage detection device is characterized bycomprising a deep sea high-pressure environment simulator, a cover body, a buoyancy material and a strain detector. The deep sea high-pressure environment simulator is connected with an underwater strain detection system. The underwater strain detection system includes a balancing weight arranged on the lower end face of the buoyancy material, a high-precision force detection rod connected to thebuoyancy material, and a high-sensitivity strain gauge arranged on the high-precision force detection rod. The high-sensitivity strain gauge is conveyed to the position of a middle section of the high-precision force detection rod; the high-sensitivity strain gauge is connected with the strain detector arranged at the outer side of the deep sea high-pressure environment simulator; and the straindetector is in electric signal connection with a computer. According to the invention, accurate detection can be carried out once; a damage time point can be timely and accurately captured; and the massive detection work load of starting and sealing a high-voltage container multiple times is avoided, so that the operation flow is simplified.

Description

technical field [0001] The invention relates to the field of hydrostatic pressure detection of buoyancy materials, in particular to a hydrostatic pressure damage detection device and detection method for full-sea deep buoyancy materials. Background technique [0002] In recent years, with the continuous advancement of the national maritime power strategy, human exploration of the ocean has also continued to deepen, especially the deep waters below 6,000 meters have received extensive attention. Due to the special pressure of the marine environment in the deep sea area, human beings must use marine engineering equipment such as manned submersibles, unmanned submersibles and landers to carry out resource and environmental exploration. The successful diving and surfacing of marine engineering equipment must rely on the huge buoyancy provided by the low-density, high-strength composite floating body material underwater. At present, composite buoyancy materials have been widely ...
