In recent years, along with the rapid development of the offshore sea area abalone aquaculture industry, the offshore sea area does not have enough space to meet the increasing abalone aquaculture demand, and the abalone aquaculture platform can effectively alleviate this current situation as a steel structure device that can carry out abalone aquaculture in the deep and open sea area, therefore abalone aquaculture platform has huge development potential and market prospect.
As a steel structure device capable of culturing abalones in deep and open sea areas, the structure of the steel structure device needs to ensure the sealing performance of each watertight cabin, and the problems of water leakage, sinking and the like can be avoided when the steel structure device is operated on the sea. Therefore, leakage tests must be performed on each watertight compartment of the abalone culture platform before the platform is actually launched.
At present, for the leakage inspection of an abalone culture platform, the common method is that fresh water is filled into each cabin in the culture platform after the structural integrity of the culture platform is completed in the stage of building on a flat ground, and professional inspectors perform visual inspection on each exposed welding line of the culture platform outside the platform. The method is time-consuming, labor-consuming and low in efficiency, and simultaneously causes great waste of fresh water resources.
