The invention discloses a tidal current energy power generation blade surface pressure testing device. The tidal current energy power generation blade surface pressure testing device comprises a flow deflector, a water sealing shell, a machine core, a shaft head and a pressure sensor. A hollow transmission shaft of the machine core is fixed to an installation plate in the water sealing shell through a thrust bearing, the front end of the hollow transmission shaft is connected with a shaft shell key of the shaft head at the front end of the water sealing shell, a blade can be installed on the cylindrical lateral face of the shaft shell, the pressure sensor is attached to the blade, and a signal line penetrates through a cavity of the hollow transmission shaft to enter the interior of the water sealing shell. An electric conduction sliding ring is fixed to the hollow transmission shaft in a sleeving and buckling mode to rotate along with the hollow transmission shaft, is connected with a signal line of the pressure sensor to be used for transmitting pressure measurement signals in the rotating process, and a signal cable of the electric conduction sliding ring is led out from the back end of the water sealing shell to be connected with a water data collection system outside the testing device. The testing device can be fixed to a trailer on a water channel for traction or fixed to the interior of a water channel with the flow creating function; data of pressure on the surface of the blade driven by tide are measured, and analysis of measurement of the pressure on the surface of the blade in different wing models, different numbers and different lead angle combinations in various flow velocity states is achieved.
Description
technical field [0001] The invention relates to a tidal current energy generating test device, in particular to a tidal current energy generating vane surface pressure testing device. Background technique [0002] Tidal energy refers to the kinetic energy of seawater flow in ocean tidal movement. Compared with wave energy, the change of tidal energy should be stable and regular. my country's coastal waters are rich in tidal current energy resources, and the research and development of tidal current energy generation devices is of great significance to the development and utilization of marine renewable energy. The research and development of tidal current energy generation devices in my country has entered the stage of engineering prototype development. Blades are the key components of tidal current energy generation devices. The research and development of high-capacity blades has a major impact on tidal current energy generation. [0003] However, there is currently no co...
