Load adjustable tidal current energy generating device

Abstract

The invention provides a load adjustable tidal current energy generating device. The device comprises a frame, at least four water turbines, at least four generating die sets and at least four load adjusting die sets, wherein the at least four water turbines are arranged in parallel in the frame; the axis of each water turbine is in the direction vertical to the level; the at least four generating die sets are respectively connected with the at least four turbines; the at least four load adjusting devices are arranged at the frame and positioned at the upstream of the at least four turbines in the water running direction; each load adjusting die set comprises at least one water guide plate, a rotating mechanism and a driver; when the water running speed exceeds the preset running speed, the drivers drive the rotating mechanisms to rotate the water guide plates until the water guide plates are opened; when the water running speed is less than or equal to the preset running speed, the drivers drive the rotating mechanisms to rotate the water guide plates until the water guide plates are closed. With the adoption of the device, the generating die sets can be effectively adjusted to ensure efficient and stable generating.

Description

technical field [0001] The invention relates to a tidal current energy generating device, in particular to an adjustable load tidal current energy generating device. Background technique [0002] Nowadays, energy is increasingly scarce, the greenhouse effect is becoming more and more serious, and energy needs to be low-carbon. Therefore, wind energy, ocean energy (including tidal energy, tidal current energy, wave energy, ocean current energy) and other clean energy are the development direction of future energy. But now these clean energy power generation equipment, in addition to the relatively mature utilization of wind energy, the utilization of ocean energy is still in its infancy, there is no general and mature equipment, the efficiency is low, and the equipment cannot be scaled up. [0003] Traditional ocean energy power generation devices generally only use one or two hydroelectric generators. However, only one or two hydroelectric generators are used. In order to i...

Problems solved by technology

However, once the water flow speed increases, the power generation module will not work, which greatly reduces the power generation efficiency and wastes ocean energy.

[0006] Therefore, the existing ocean energy power generation devices have problems such as unstable power generation, large fluctuations, and excessive investment to prevent commercialization.

Moreover, the electric energy generated by existing ocean energy power generation devices cannot be directly exported for use.
