Abstract

The invention discloses a vortex-induced vibration water flow energy power generation device and belongs to the technical field of renewable energy sources. The vortex-induced vibration water flow energy power generation device comprises a seabed base, a supporting frame, an energy capturing and transmitting device and a power generation device body. The whole device is fixed in a water flow basin through hook claws at the bottom of the seabed base, and water flow energy in incoming flow is captured and converted into available electric energy. Based on the principle of the classical vortex-induced vibration phenomenon in fluid mechanics, the device converts water flow energy into kinetic energy of a cylindrical vibrator, drives an electromagnetic generator to generate electricity through a connecting device, and can stably capture water flow energy in a low-speed drainage basin. In addition, the vortex-induced vibration water flow energy power generation device adopts symmetrical design, can drive two power generators at one time, improves the power generation efficiency, is simple in overall structure and convenient to maintain and manage, does not affect the ecological environment, and meets the standard of clean new energy.

Description

technical field [0001] The invention relates to a vortex-induced vibration water current energy generating device, which belongs to the field of clean new energy development. Background technique [0002] In recent years, with the gradual depletion of fossil energy, the development of new environmentally friendly and renewable energy has become a top priority. Among them, tidal current energy stands out from the crowd of green and sustainable energy with its characteristics of "sustainability, high energy density, and rich content", and has become a hot issue in the field of energy research. Compared with wind energy, the acquisition of water flow energy is more stable and does not need to deal with harmonic problems. At present, my country has a coastline of more than 5,000 kilometers and a wide variety of rivers and lakes, which means that it has a considerable amount of water flow energy reserves. Therefore, it has broad research prospects. [0003] At present, the mai...
