Embodiment Construction
[0032] The present invention proposes a test device for studying the influence of wind and waves on wind turbines, which includes a seat with adjustable inclination angle, a transparent box on the seat, a wind turbine model, a wave pump 2, a blower assembly and an image test assembly.
[0033] The seat body includes a horizontally placed fixed seat 13 and a rotating installation groove 14 on the fixed seat 13; one end of the rotating installation groove 14 is connected to the fixed seat 13 through a horizontal rotating shaft; the opposite end of the rotating installation groove 14 is connected to The fixing base 13 is connected by a rigid support bar 15. When in use, the rotating mounting slot 14 is rotated to a specified angle along the horizontal axis, and a rigid support bar 15 of appropriate length is selected to rivet the opposite end of the rotating mounting slot 14 and the fixing seat 13 to form a stable triangular structure support frame.
[0034] The transparent box 1 is f...

The invention provides a testing apparatus for researching influence of wind and waves to a wind generation set. The testing apparatus comprises an inclination angle adjustable base, a transparent boxlocated on the base, a wind generation set model, a wave making pump, an air blower assembly and an image testing assembly. Transparent soil and water on the transparent soil are paved at the bottomof the transparent box; a basic foundation of the wind generation set model is buried and fixed in the transparent soil; the wave making pump is located in water to make an artificial water flow; theair blower assembly applies a wind pressure to water rand the wind generation set model; the image testing assembly is placed out of the side wall of the transparent box to photograph dynamic evolution of the transparent soil. The angle of the transparent box is adjustable, so that a test on angle of an underwater side slope can be simulated. By setting different frequencies of the air blower, different wind loads are simulated; the wind direction is set by means of rotating a bracket; various wave loads are simulated by means of the wave making pump; and the structures simulate complicated and changeable conditions of sea wind and waves precisely, so that the experimental reliability is high.
Description
Technical field [0001] The invention relates to the technical field of ocean engineering, and specifically relates to a test device and a test method for studying the influence of wind and waves on wind turbines. Background technique [0002] Wind power has become one of the most mature technologies, the most large-scale development conditions and commercial development prospects in the field of renewable energy. Offshore wind farms have the advantages of high wind speed, low turbulence, low wind shear, and high output. The development of wind power generation is of great significance for solving the energy crisis, mitigating climate change, and adjusting the energy structure. [0003] Although offshore wind farms have many advantages, compared with onshore wind farms, the service environment of offshore wind farms is more severe and complicated. At this stage, common types of offshore wind power foundations at home and abroad include suction foundations, single-pile foundations, ...
