Modularized ocean energy power generation device

Abstract

The invention provides a modularized ocean energy power generation device. The modularized ocean energy power generation device comprises an outer framework, at least one inner framework and at least one hydraulic turbine generator module, wherein at least one inner framework can be separably arranged in the outer frame. At least one hydraulic turbine generator module is arranged in the inner framework. The modularized ocean energy power generation device is provided with at least one internal module, and the hydraulic turbine generator modules can form arrayed arrangement by regulating number of the internal modules. The inner framework and the outer framework can be separably arranged, so that the modularized assembly is realized, and the maintaining and mounting cost is greatly reduced.

Description

[0001] This application is a divisional application with an application date of March 4, 2014, an application number of 201410076524.9, and an invention title of "modular ocean energy power generation device". technical field [0002] The invention belongs to the field of ocean energy power generation, and in particular relates to a modular ocean energy power generation device. Background technique [0003] Ocean energy (including tidal current energy, wave energy, and ocean current energy) refers to the energy of seawater flow. As a renewable energy source, it has abundant reserves and wide distribution, and has excellent development prospects and value. The use of ocean energy is mainly to generate electricity, and its working principle is similar to that of wind power and conventional hydropower, that is, the mechanical energy of seawater is converted into electrical energy through an energy conversion device. Specifically, first seawater hits the water turbine, and the w...

Problems solved by technology

However, the maintenance and replacement of traditional ocean energy power generation devices are also carried out in the sea, which is difficult and costly

Even, due to the damage of some components, the entire ocean energy generating device is scrapped, which is one of the important reasons for the high cost of the ocean energy generating device, and it is also the direct reason why the existing ocean energy generating device cannot be operated on a large scale and commercially. reason

[0006] Horizontal axis hydro-generators in particular are more difficult and costly to repair since all their equipment, including the impeller and generator, is submerged

Therefore, even though the power generation efficiency of the horizontal-axis hydro-generator is higher than that of the vertical-axis hydro-generator, the horizontal-axis hydro-generator still cannot be commercialized

However, at present, technicians in the field of ocean energy generation have ignored the improvement of maintenance methods

[0007] In addition, in order to increase the power generation of traditional ocean energy power generation devices, the diameter of the impeller usually needs to be made very large, which will greatly reduce the speed of the impeller and increase the torque at the same time, resulting in increased friction between the central shaft and the gearbox. Rising costs for shafts and gearboxes

In addition, the scale of the entire power generation device will be limited, and the cost of the power generation device will remain high, which restricts the development of ocean energy power generation devices

[0008] However, at present, technicians in the field of ocean energy power generation have technical prejudices, and only focus on the research and development of how to enlarge the impeller part of the hydro-generator or improve the structure of the impeller blades to increase the power generation of a single hydro-generator

At present, no one in this field has studied how to increase the power generation and reduce the cost to be suitable for commercial use without changing the impeller.
