Description
Technical Field
The invention belongs to the technical field of offshore wind turbines, and relates to an offshore wind turbine foundation flushing experiment device with a rotatable base.
Background
Offshore wind power is an important development direction of clean energy. At present, china forms a complete offshore wind power technology industrial chain in the southeast coastal region, and the energy structure of surrounding cities is greatly optimized. However, as the service life of the offshore wind power foundation structure increases, the problem of local scouring of the foundation is gradually exposed, so that the bearing capacity of the foundation is reduced, the transverse stress is unbalanced, and the stability of the offshore wind power foundation is seriously affected. Once the offshore wind power foundation is destroyed, huge economic loss is brought, the tide characteristics of the southeast coastal area in China are closely related to the topography, most of the sea areas belong to strong tide areas, and the sea areas belong to regular half-day tide types, and the shallow water effect is obvious. Therefore, the tidal current effect has a larger influence on the local scouring of the offshore wind power foundation, and the different tidal current effect directions are key factors for researching the scouring characteristics of the offshore wind power foundation.
The current laboratory water tank can only give unidirectional reciprocating water flow or waves, different incoming flow directions can not be set for a single pile foundation structure, and the dredging characteristics of the offshore wind power foundation structure in different tide action directions can not be mechanically studied. Therefore, a need exists for a test device for a single-pile foundation rotating disc of offshore wind power, which can simulate different tide action directions, and further reveals a dredging mechanism of an offshore wind power foundation structure under the tide action, so that a comprehensive and objective analysis method for the local dredging characteristic of the offshore wind power foundation is formed, and the safety of the offshore wind power structure is ensured.

By adopting the structure, when the positioning shaft sleeve is used, the positioning shaft sleeve is pulled out outwards, the rotating shaft drives the rotating block to rotate, the rotating block drives the first bevel gear to rotate, the first bevel gear drives the second bevel gear to rotate, after the adjustment is finished, the positioning shaft sleeve is pushed inwards, the positioning clamping block is clamped at the outer side of the positioning gear, and the position of the rotating shaft is limited. Because the limiting effect of the locating shaft sleeve limiting clamp and the locating clamping block is achieved, at the moment, the direction of the rotating shaft can be adjusted by manually rotating the rotating shaft on the side face of the rotating block, so that the disc bottom plate is driven to rotate through the vertical bearing, the direction of the disc bottom plate is adjusted, the offshore wind power single pile foundation rotating disc test in different tide action directions is simulated, the problem that a laboratory water tank can only give unidirectional reciprocating water flow or wave, different incoming flow directions are difficult to set for a single pile foundation structure, and the problem that the flushing and silting characteristics of the offshore wind power foundation structure in different tide action directions cannot be mechanically studied is solved. Meanwhile, the positioning fixture block arranged in the groove is clamped on the outer side of the positioning gear in the using process, so that the rotating shaft can be locked, and the rotating shaft is fixed.
