Multidirectional self-adaptive suspension type tidal energy hydraulic turbine

Abstract

The invention relates to a multidirectional self-adaptive suspension type tidal energy hydraulic turbine which comprises an upper balance wing, a lower balance wing, a flow-guide cover, a turbine blade, a power generator, a connecting and fixing rod and an anchor ring, wherein the upper balance wing and the lower balance wing are respectively installed above and below the flow-guide cover; the turbine blade is fixed at the outer side of a rotor of the power generator; the power generator is fixed on the flow-guide cover through the connecting and fixing rod; and the anchor ring is installed at the outer side of the flow guide cover. The flow guide cover has the self-suspension function and good anti-overturning stability. After the multidirectional self-adaptive suspension type tidal energy hydraulic turbine is installed, a suspension system can be subjected to real-time downstream gesture adjustment according to the tide flow direction change to ensure that the flow direction is consistent with an axis of the flow-guide cover, that is the flow direction is vertical to the rotation plane of the blade. The multidirectional self-adaptive suspension type tidal energy hydraulic turbine has very remarkable conflux effect and can ensure that a tidal energy power generation system has considerable power generation efficiency at the smaller velocity.

Description

technical field [0001] The invention relates to a tidal energy water turbine, in particular to a multidirectional self-adaptive suspension type tidal energy water turbine applicable to sea areas where the velocity of ocean currents is not high and the incoming flow direction changes frequently, and belongs to the field of marine energy equipment. Background technique [0002] 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 2m / s is equivalent to a wind speed of 18.8m / s with a wind speed of level 8. Moreover, the current is mainly caused by the gravitational effect of the moon, which is more regular than the wind energy c...
