Problems solved by technology

Compared with the horizontal axis impeller device, the most prominent advantage of the conventional vertical axis impeller device is that it is not affected by the change of the incoming flow direction and does not require a steering mechanism; Among them, the instantaneous load fluctuation amplitude of the impeller is large, which is not conducive to the reliability of the impeller operation and the stability of the power output

Abstract

The invention relates to a spiral blade based vertical axial tidal current energy impeller apparatus. The apparatus includes a main shaft and at least two wheel discs arranged in parallel on the mainshaft. The wheel disc is provided with a plurality of spoke mechanisms arranged equally spaced along the circumferential direction of the wheel discs. The spoke mechanisms include spoke wing-shaped plates and rectangular spoke plates and wing-shaped spoke plates respectively arranged on the inner ends and outer ends of the spoke wing-shaped plates, and also includes spiral blades which are staggered to connect the spoke mechanisms on the upper and lower wheel discs. The spiral blades are fixedly connected to the wing-shaped spoke plates in the spoke mechanisms. A plurality of equally spaced wing-shaped rectifier cells are fixedly connected to the spiral blades. The advantages of the apparatus are that the spiral blade based vertical axial tidal current energy impeller apparatus is simple in structure, reliable in operation, stable in electric energy output and convenient in installation and disassembly, and is suitable for engineering application.

Description

technical field [0001] The invention belongs to the field of hydraulic machinery and hydraulic engines, in particular to a vertical axis tidal current energy impeller device based on spiral blades. Background technique [0002] Tidal current energy is a renewable and clean energy that accompanies the ebb and flow of tides. my country's exploitable tidal current energy resources rank first in the world. [0003] In the process of tidal current energy conversion, the impeller device of tidal current generator is a key hydrodynamic component for the development and utilization of tidal current energy. It mainly consists of main shaft, blades and related connection and adjustment control mechanisms. According to the relationship between the incoming flow direction and the impeller rotation axis, the tidal current impeller devices can be divided into horizontal axis type and vertical axis type. The main axis of the horizontal axis tidal energy impeller device is parallel to the...
