Comprehensive stimulation system for realizing coupling effects of wave, current and wind in water tank

Abstract

The invention discloses a comprehensive stimulation system for realizing the coupling effects of wave, current and wind in a water tank, which comprises the water tank, a wave making machine for generating wave in the water tank, a wind making system and a current generation system. The current generation system comprises current generation pools arranged under both ends of the water tank, a hydrophobic gate which is arranged on the bottom surface of the water tank and is communicated with the water tank and the current generation pools, a current generation pipeline which is arranged outside the water tank and is connected with the current generation pools at both ends, and a water pump arranged on the current generation pipeline, wherein the current generation pipeline is provided with a water inlet and a water outlet. The wind making system comprises a fan cover which has a certain distance from the wave making machine and is arranged above the water tank; the fan cover extends to one end of the water tank which is far away from one side of the wave making machine; an airduct is arranged above the water tank at the tail end of the fan cover; the inside of the airduct is provided with a fan; and the fan cover, the airduct and the water tank are hermetically connected to form a wind tunnel. The comprehensive stimulation system can integrally and truly simulate hydrodynamic environments of harbors, seacoasts and offshore by comprehensively generating the wave, the tidal current and the wind in real time in the water tank.

Description

technical field [0001] The invention relates to the field of experimental research on ports, coasts and offshore engineering, in particular to a comprehensive simulation system for realizing the coupled effects of waves, currents and winds in a water tank. Background technique [0002] With the development of the national economy and the improvement of the technical level of port construction, port construction is developing in the direction of deep water and large-scale, and there are more and more open wharves. The construction of a port in a deep-water area will inevitably face the natural conditions of large waves and rapid currents. The dynamic environment of ports, coasts and offshore waters is mainly composed of three dynamic factors: waves (hereinafter referred to as "waves"), tidal currents (hereinafter referred to as "flows") and wind. These three factors are the main external loads borne by the buildings of the port engineering. Only by comprehensively considering...

Problems solved by technology

[0005] However, at present, in the physical simulation experiment system of ports, coasts and offshore engineering, there is only the coupling effect of wave and current, or only the coupling effect of wave and wind

These two situations can still meet the requirements for the analysis of relatively simple or single ocean dynamics on the impact of port engineering buildings, but for experimental research that needs to be more realistically close to the natural environment, there will be relatively large errors, and even the experiment cannot be carried out Research
