Description

Technical Field

[0001] The utility model belongs to the technical field of offshore wind power pile foundation experiments, in particular to a three-way disturbance test device for an offshore wind power pile foundation. Background Art

[0002] At present, in the construction process of offshore wind power generation, due to the relatively soft soil under some oceans, it will flow when disturbed by water flow and washed by ocean currents, resulting in scour pits around the pile foundations of offshore wind turbines, endangering the stability of wind power generation equipment. Therefore, before the construction of offshore wind power generation, it is necessary to use a three-way disturbance test device for offshore wind turbine pile foundations to conduct experiments.

[0003] The three-way disturbance test device for offshore wind power pile foundation in the prior art is composed of a simulation box, a water pump, a pile foundation sand table and other structural components. The water pump sprays flowing water to form a water flow inside the simulation box. The displacement, deformation or damage of the rock and soil body is observed through the water flow scouring experiment. However, it has no water nozzle adjustment function, and the water spray direction is fixed. It cannot simulate the actual ocean current conditions at the offshore wind power construction site, which reduces the accuracy of the experiment and is not conducive to people's use. In order to solve the above problems, we propose a three-way disturbance test device for offshore wind power pile foundation. Utility Model Content
