Embodiment Construction

[0069]In the early days of wind power generation, there was a so-called diffuser augmented wind turbine (DAWT for short), which could be used to increase power generation. The applicant used this diffusion-gained impeller design concept in the flume test section, and used the figure 1 As an illustration. figure 1 Schematic diagram of the impeller placement for the existing diffusion gain test section of the flume. Please refer to figure 1 , figure 1 The impeller 50 of the diffusion gain includes an impeller 52 and a shroud 54 . The applicant placed the impeller of this diffusion gain in the test section of the flume, and took the test section of the flume as the artificial boundary B. Compared with placing the diffusion-enhancing impeller in the open sea, it was found that under the same inflow and operating conditions, the torque generated by the diffusion-enhancing impeller 50 placed in the tank test section was much greater than that of the diffusion-enhancing impeller ...

Abstract

An ocean current power generating apparatus using a dual-duct is provided. The ocean current power generating apparatus with dual-duct includes at least one power generating unit. The power generating unit includes a turbine (110, 710), an inner duct (120, 420, 720) and an outer duct (130, 430). The turbine has a shaft box (112, 412, 712). The turbine is located inside the inner duct. An outer diameter (D3) of an inflow side of the inner duct is less than an outer diameter (D4) of an outflow side of the inner duct. The outflow side of the inner duct is located inside the outer duct. An outer diameter (D1) of an inflow side of the outer duct is less than an outer diameter (D2) of an outflow side of the outer duct.

Description

technical field [0001] The present invention relates to an ocean current power generation device, and in particular to an ocean current power generation device with a unidirectional double-layer guide cover controlled by a boundary layer. Background technique [0002] Since petroleum, coal and other energy sources are non-renewable, the use of renewable natural energy is the trend of human life and the development of science and technology. Especially, the ocean currents are widely distributed and have huge energy, so the utilization of ocean current energy has high value. [0003] The existing ocean current power generation device utilizes fluid flow to make the fluid pass through the impeller to drive the generator to rotate and generate electricity. However, this kind of ocean current power generation device still needs sufficient flow velocity and flow to generate electricity effectively. In addition, the generating power of the ocean current power generation device is ...
