Problems solved by technology

At present, among domestic scale model experimental devices similar to simulating dynamic cable motion under real sea conditions, there is no device that can simultaneously simulate ocean currents, waves, and floating body motion, and there is an urgent need for a device that can completely reproduce the real in-situ operating conditions of umbilical cables. Scaled model experimental device to study the hydrodynamic response characteristics of the overall line shape of the dynamic cable for offshore wind power in-situ operation, and then provide experimental method support for the line shape design of dynamic cables in my country

Abstract

The invention belongs to the technical field of marine flexible pipe cable experimental testing, and particularly relates to an overall linear hydrodynamic response experimental device for a marine wind power dynamic cable. Circulating flowing of water is achieved through the concentric-square-shaped structure of a water tank and a flow making mechanism, multiple marine dynamic cable in-place operation working conditions can be simulated by controlling a flow making device, a wave making device and a six-degree-of-freedom mechanism, a certain working condition can be experimentally simulated,the overall linear hydrodynamic response characteristics of a pipe cable under the complex condition of combining multiple working conditions can be experimentally simulated, and the overall linear hydrodynamic response characteristics of the ocean dynamic cable under the working condition of stable water flow can be tested and simulated.

Description

technical field [0001] The invention belongs to the technical field of experimental testing of marine flexible pipe cables, and in particular relates to an integral linear hydrodynamic response experimental device for marine wind power dynamic cables. Background technique [0002] With the growth of energy demand and the pursuit of renewable energy, offshore wind power has attracted more and more attention due to its stable energy and large scale. Submarine cables play an indispensable role in offshore wind power generation. In the power system, the electric energy output by the wind turbines is collected to the offshore substation through the cables laid on the seabed, and then connected to the onshore substation through the submarine cable and integrated into the power grid. In shallow waters, wind power equipment is generally fixed on the seabed, and the statically designed submarine cables can be used in shallow water environments; in deep waters, floating platforms are ...
