Abstract

The invention discloses a permanent magnet semi-direct-drive type tidal power generation device. The permanent magnet semi-direct-drive type tidal power generation device comprises a blade system, a transmission system, a power generation system, an alternating current system, a control system and a support system. The permanent magnet semi-direct-drive type tidal power generation device disclosed by the invention has the beneficial effects that the device can utilize tidal current energy for power generation and is safe and environment-friendly; the semi-direct-drive combination of a simple transmission device and a permanent magnet motor is adopted so as to be suitable for low water speed and low rotational speed, high in energy transformation ratio and good in power generation benefit; the underwater structure of the system is simple, the service life is long, the maintenance is simple and convenient, and the maintenance cost is low; the semi-direct-drive structure avoids the use of the low-speed permanent magnet motor, the blade system eliminates a yawing and pitch control system, the process requirements are low, and the technical implementation is easier than the direct drive type; and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a power generation device, in particular to a device for generating power by utilizing ocean tidal current energy. Background technique [0002] With the rapid development of society and economy, human beings are facing serious problems such as resource scarcity, energy shortage, climate change and environmental degradation. All countries in the world today are seeking scientific ways to solve resource and environmental problems, and are moving towards an environmentally friendly and sustainable development model. Among them, the large-scale development and utilization of "marine renewable green new energy" including tidal current energy has become a current research hotspot. . Oceans account for more than 70% of the earth's surface area. my country is adjacent to the Northwest Pacific Ocean, has a long and tortuous coastline of more than 18,000 kilometers, and has about 3 million square kilometers of sea areas under national ...
