Anti-scouring negative pressure multi-barrel combined offshore wind turbine base combined with artificial fish reefs

Abstract

The invention discloses an anti-scouring negative pressure multi-barrel combined offshore wind turbine base combined with artificial fish reefs. The anti-scouring negative pressure multi-barrel combined offshore wind turbine is characterized in that annular connecting chambers are welded among negative pressure barrels, an integral annular structure is formed, annular top plates and transition sections are arranged at the upper parts of the negative pressure barrels, and guide pipe racks are connected to the upper parts of the transition sections; an arranged flow reducing net is composed of asteel pipe frame and a polythene net, the steel pipe frame and the annular connecting chambers are welded, and the steel pipe frame and the annular top plates are poured together; an anti-scouring net grid which is of a meshy structure formed through connecting nylon ropes and waste tyres is arranged, and an artificial fish reef group is uniformly pressed on the anti-scouring net grid; and negative pressure pumping openings are formed in the tops of the negative pressure barrels and the upper parts of the annular connecting chambers, and the negative pressure pumping openings penetrate through the annular top plates above, and are connected with negative pressure pumping equipment. The anti-scouring negative pressure multi-barrel combined offshore wind turbine base has the beneficial effects that compared with present offshore wind turbine bases, the anti-scouring negative pressure multi-barrel combined offshore wind turbine base has the advantages that construction cost of the offshore wind turbine base and artificial fish reefs is reduced, the anti-scouring capacity of the offshore wind turbine base is improved, adverse effects of offshore wind turbines on the marine environmentare reduced, and ecological benefits of an offshore wind plant are improved.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power generation foundation structures, and in particular relates to a negative pressure multi-barrel combined foundation with the function of multiplying fish and reefs and having the ability to resist erosion. Background technique [0002] In recent years, offshore wind power, as a green and clean renewable energy, has developed rapidly and has broad development prospects. Offshore wind power has significant advantages such as high annual average wind speed, low turbulence, no land occupation, high annual utilization hours, and close distance to power consumption centers. However, due to the complex offshore environment, compared with land-based wind turbines, offshore wind turbines are subject to the combined action of wind, wave and current, and the load conditions are more complicated, and seawater has obvious erosion and erosion effects on the foundation, so offshore wind power has hig...

Problems solved by technology

In order to achieve the joint development and positioning of the two, it is necessary to first solve the problem of turbid seawater caused by the scour of the fan foundation. The current fan foundation form and anti-scouring measures cannot solve the problem of sanding and sanding.
