Floating body type dual-impeller tidal current energy power generating device

Abstract

The invention discloses a floating body type dual-impeller tidal current energy power generating device, comprising a floating body (1), impellers (2), a speeder (3) and a power generator (4); the impeller shafts of the two impellers are horizontally arranged; the two impellers (2) are arranged at two sides of the floating body (1) respectively, and are connected with the input end of the speeder (3); the out put end of the speeder (3) is connected with a power shaft of the power generator (4); and a mooring system is arranged at the front end of the floating body (1) provided with a water injecting chamber (1.1). The horizontally arranged impeller shafts have the flow guiding function and part of the impellers is arranged above the water, so the tidal current energy power generating device is high in automatic power generating efficiency for water, and convenient to mount and maintain.

Description

technical field [0001] The invention relates to an energy capture device, more specifically to a floating body type double impeller tidal current energy generating device. Background technique [0002] Tidal current energy is a clean and non-polluting renewable new energy with abundant reserves. With the continuous depletion of fossil energy and the continuous improvement of environmental protection requirements, countries all over the world pay more and more attention to the development and utilization of tidal current energy, and use various forms of energy harvesting devices to carry out The technology of tidal current power generation has been continuously broken through. [0003] Various known tidal current energy power stations can be divided into floating type, pile foundation type and seabed type according to the form of power generation platform. The structure of the floating power station is relatively simple, the manufacturing technical requirements for the float...

AI Technical Summary

Problems solved by technology

However, the outstanding problems of the existing floating tidal current power generation devices are: (1) In the case of low water flow velocity, the speed of the impeller is limited, so the power generation efficiency is not high; (2) the current floating power generation devices are generally single The impeller, the impeller shaft is arranged vertically, generally using S-shaped or H-shaped blades, and all the blades are located underwater

Under the action of water flow, some of the blades are impacted to make them rotate, but the other part of the blades are affected by the water flow and hinder their rotation, so the overall efficiency is not very high
