Embodiment Construction

[0012] The present invention will be further described below with reference to the drawings and embodiments.

[0013] The hydrodynamic performance test device of the vertical axis tidal energy water turbine blade of the present invention includes a rotating shaft 1, a sliding sleeve 2, a handle 3, a fixed shaft 4, a sliding rail A5, a pin B6, a mounting hole 7, a variable deflection angle mechanism 8, a bracket 9, and an adjustment Bolt 10, lower holding block 11, upper holding block 12, blade 13, filler 14, blade shaft 15, slide rail a16 and pin b17. The shaft 1 is matched by a cylindrical sliding sleeve 2 and a cylindrical fixed shaft 4 The sliding sleeve 2 and the fixed shaft 4 are made of magnesium-aluminum alloy material, which not only meets the need for strength, but also greatly reduces the energy consumption of the unit. Between the sliding sleeve 2 and the fixed shaft 4, there is a slide rail A5, and the shaft 1 The shaft length can be adjusted to facilitate the test of...

Abstract

A hydrodynamic performance test device for blades of a vertical axis tidal energy hydroturbine comprises a rotating shaft, a sliding sleeve, pull handles, a fixed shaft, a sliding rail A, a pin B, mounting holes, variable-deflection-angle mechanisms, supports, adjusting bolts, a lower embracing blocks, upper embracing blocks, blades, fillers, blade rotating shafts, sliding rails a and pins b. The rotating shaft is formed by matching of the sliding sleeve and the fixed shaft, the sliding rail A is arranged between the sliding sleeve and the fixed shaft, the sliding sleeve is provided with the pull handles, the pin B and the mounting holes, the variable-deflection-angle mechanisms are mounted around the sliding sleeve through the supports, the sliding rails a and the pins b are arranged on the supports, each upper embracing block is connected with the corresponding lower embracing block with the bottom provided with one blade rotating shaft through the bolts to be fixed on the corresponding support, each blade is formed through the fillers by means of solidification and then fixed in a rectangular groove between each upper embracing block and the corresponding lower embracing block, and the adjusting bolts are arranged at two bottom ends of each blade to adjust dimensions of blade swing limit angles. Therefore, the device solves the problem that an existing test device is incapable of analyzing influencing factors and the like of electricity generation performance of the hydroturbine in detail independently.

Description

Technical field [0001] The invention relates to a vertical-axis tidal current energy water turbine blade hydrodynamic performance test device, which belongs to the field of tidal current power generation test tools. Background technique [0002] With the development of the world economy, non-renewable energy consumption and society's dependence on energy. In the past ten years, governments have turned their attention to ocean tidal current, which has huge reserves of renewable energy, and have increased the research and development of tidal current power plants and their key technologies. Compared with conventional energy, tidal current energy has the advantages of large energy reserves, good predictability, relatively small environmental impact and no pollution. As the most important tidal energy conversion device, hydraulic turbines convert fluid kinetic energy into mechanical energy. However, traditional paddle and Francis turbines reduce the energy utilization rate due to th...
