Experimental device suitable for coupling motion of ice and ocean structure in normal-temperature water pool

Abstract

The invention discloses an ice and ocean structure coupling motion experimental device suitable for a normal-temperature pool, an ocean platform model is moored at the bottom of the pool, model ice is arranged in the pool, and the device is installed above the pool. Comprising a fixing support used for installing the device above a pool, a space adjusting mechanism used for adjusting the relative position between model ice, a lifting mechanism used for longitudinally adjusting the position of the model ice and limiting the horizontal displacement of the model ice, and an extension mechanism used for being matched with the lifting mechanism to adjust the position of the model ice. According to experimental research requirements, the relative position between the simulated floating ice area and the mooring floating platform can be accurately controlled, the floating ice concentration and the spatial distribution form of the floating ice in the floating ice area can be flexibly adjusted, meanwhile, the model floating ice with the equivalent mechanical property can be used for a normal-temperature pool, a water tank and the like. Ice making and pool temperature adjustment are not needed, and compared with a low-temperature ice pool experiment, the experiment cost can be greatly reduced.

Description

technical field [0001] The invention relates to a water pool experiment device for simulating floating ice and marine structures, in particular to an ice-sea structure coupling motion experiment device which can be used in normal temperature water pools and can accurately control the position of floating ice during the simulation process. Background technique [0002] The development of traditional offshore oil and gas resources is mainly concentrated in areas such as the Gulf of Mexico, the Persian Gulf, the South China Sea, the Gulf of Guinea in West Africa, and deep water in Brazil. As the core equipment for drilling and production of offshore oil and gas resources, offshore platforms mainly bear wind, waves, currents and other loads in these areas. , the relevant load evaluation methods can basically meet the design requirements of engineering equipment. However, with the increasing human demand for oil and gas resources and the stable or declining production of traditio...

Problems solved by technology

However, it is difficult for this device to realize the coupled movement experiment of small-scale sea ice and marine structures in the wave field, and it is impossible to accurately control the relative positions between sea ice units and the sea ice array and the ocean platform during the experiment, and it is difficult to freeze ice accurately. Satisfy the mechanical equivalence of real polar sea ice, such as bending stiffness, etc., and the temperature of the pool needs to be controlled during the simulation process, which makes the experimental simulation difficult and has a large gap with the real environment, so the simulation results are not accurate enough
