Abstract

The invention discloses a multi-directional self-adaptive suspended type tidal current energy water turbine which comprises an upper balancing wing, a lower balancing wing, air guide sleeves, turbine blades, generators, connecting fixing rods and anchoring fastening rings, wherein the upper balancing ring and the lower balancing wing are installed on the upper portions and the lower portions of the air guide sleeves, the turbine blades are fixed to outer sides of rotors of the generators, the generators are fixed onto the air guide sleeves through the connecting fixing rods, and the anchoring fastening rings are installed on the outer sides of the air guide sleeves. The connecting fixing rods are three in number in a group and are uniformly arranged in a radial mode making the axis of each generator as a center, and the included angle between every two connecting fixing rods is 120 degrees. After the multi-directional self-adaptive suspended type tidal current energy water turbine is installed, a suspension system can do real-time fair current attitude regulation according to tidal current flow direction changes, the incoming flow direction is identical to the direction of the axis of each air guide sleeve, namely the incoming flow direction is vertical to the rotating plane of the blades, flow gathering effects are highly significant, and the fact that a tidal current energy power generation system has substantial generating efficiency under a low flowing speed can be guaranteed.

Description

[0001] The present invention is a divisional application with the application number 201110095866.1, the application date is April 18, 2011, and the invention name is "multidirectional self-adaptive suspension type tidal current energy turbine". technical field [0002] The invention relates to tidal energy power generation equipment, in particular to a multi-directional self-adaptive suspension type tidal energy water turbine suitable for sea areas where the ocean current velocity is not high and the incoming flow direction changes frequently. Background technique [0003] Tidal current energy is a renewable form of energy generated by the flow of sea water caused by tidal fluctuations. The utilization principle of tidal current energy is similar to that of wind power generation, and its power generation device is vividly compared to an "underwater windmill". Since the density of seawater is more than 800 times that of air, the more common sea current energy flow density of...
