Shallow submerged floating horizontal axis ocean current power generation system with shroud

Abstract

The invention provides a shallowly-submerged floating type horizontal axis current power generation system with a flow guide cover or flow guide covers and belongs to the ocean current energy development technical field. The shallowly-submerged floating type horizontal axis current power generation system is of an array structure which is formed by one or more than one current power generation device; every current power generation device comprises a power generation mechanism and a floating body mechanism, wherein the power generation mechanism is arranged inside a flow direction adaptive flow guide mechanism and the floating body mechanism is connected with the flow direction adaptive flow guide mechanism; every floating body mechanism comprises a floating ball and a wing-shaped floating body which are arranged at the top of the bottom of the corresponding flow direction adaptive flow guide mechanism respectively; every flow direction adaptive flow guide mechanism comprises the glow guide cover, turbine blades and a streamlined cabin, wherein the flow guide cover faces the direction of the ocean current and the turbine blades and the streamlined cabin are arranged in the flow guide cover in turn. According to the shallowly-submerged floating type horizontal axis current power generation system with the flow guide cover or covers, the power generation can be driven by the kinetic energy of the ocean current, the shallowly-submerged floating type horizontal axis current power generation system is suitable for the stable ocean current and sea condition, the energy conversion rate is high, and one to three megawatts every hour of power can be generated after the shallowly-submerged floating type horizontal axis current power generation system is placed in the two to three meters every second of flow rate of ocean and the appropriate blade diameter is designed.

Description

technical field [0001] The invention relates to a device for developing ocean current energy, which is specifically driven by water flow to rotate turbine blades and convert mechanical energy into electrical energy. It has the advantages of low starting flow velocity, self-deflection with the incoming flow direction to obtain the maximum flow velocity, and self-balancing in any water depth. specialty. Background technique [0002] Since the sea current generator was proposed in the 1970s, it has been a hot research issue of domestic and foreign scholars and industrial circles. After years of hard work, some progress has been made. An energy acquisition method with large-scale development potential in the future. The horizontal-axis ocean current power generation turbine is a device for absorbing and converting ocean current energy. Because it can learn from wind turbines and ship propellers theoretically and technically, it has a relatively good production and manufacturing...

Problems solved by technology

However, the defect and deficiency of this technology is that the gravity of each blade of the impeller is not balanced, and the action of gravity will consume part of the work when the water flow pushes the blades to rotate, and the energy absorption efficiency of this method is limited.
