Unpowered independent deep-water operation pontoon inflating device and method

Abstract

The invention relates to a deep-water operation pontoon inflating device and a deep-water operation pontoon inflating method, and aims to provide an unpowered independent deep-water operation pontoon inflating device and an unpowered independent deep-water operation pontoon inflating method. The device comprises a pontoon, a sodium borohydride container and a tubular reactor, wherein a water outlet is reserved at the bottom of the pontoon; the upper part of the tubular reactor is connected to the upper end of the pontoon through a pipeline; the bottom of the tubular reactor is connected to the bottom of the sodium borohydride container through the pipeline; a water inlet is reserved on the upper part of the sodium borohydride container; a mechanical timing pressure open valve and a one-way valve are arranged on the pipeline of the water inlet; sodium borohydride powder is filled in the sodium borohydride container; and a porous catalyst with a three-dimensional structure is filled into the tubular reactor. The device does not need an air compressor pump; and the suspension depth of the pontoon is determined according to a set pressure of the pressure open valve, so that the suspension depth can be controlled accurately to realize timing recovery. The device and the method have a broad application prospect in the aspects such as marine scientific research, sea-bottom survey, submarine cable detection and the like.

Description

technical field [0001] The invention relates to a buoy inflation device and method for deep water operation, more specifically, the invention relates to a device and method for independently performing buoy inflation without power by using sodium borohydride hydrolysis to produce hydrogen. Background technique [0002] Marine underwater operations usually use buoys to build working platforms. The buoys are usually closed structures. The buoys can be suspended underwater by filling high-pressure gas into the buoys. However, the high pressure in the deep sea puts high demands on the compressive strength of the buoy materials. The pressure difference inside and outside the buoy can easily cause deformation and damage to the buoy, resulting in failure of the buoy. In order to solve these problems, the invention patent (CN101850835A) proposes a method for inflating steel buoys in water for deep water operations. An opening is opened at the bottom of the buoy to communicate the in...
