Abstract

The invention provides a multi-cylinder serial crankshaft type flow power generating device based on the galloping effect to overcome the defects that an existing vortex-induced vibration power generating device is small in amplitude, low in output power and the like. The large amplitude of vibrators is motivated through rough belts, a crankshaft structure of a multi-cylinder internal combustion engine is used for reference, and the high-energy output density and large-scale power generating technology of a vibrator group is achieved. The whole device set mainly comprises the cylinder vibrators with the rough belts, shaft sleeves, connecting rods, crankshafts, a power generator, connectors, springs and the like. The two ends of each vibrator with the rough belt are connected to the corresponding shaft sleeve through the corresponding connectors, and the moving consistency of the vibrators under the same connecting rod is guaranteed. The reciprocated linear movement of multiple columns of vibrators of different phases is converted into the one-way rotation movement of the same crankshaft through a crankshaft transmission mechanism. One end of each crankshaft is connected with the power generator, and mechanical energy is converted into electric energy. According to the device, the centralized collecting of vibration energy of the vibrator group is achieved, the device can be widely applied to collection of river and ocean current energy, and high practicability and economic efficiency are achieved.

Description

technical field [0001] The invention relates to a new energy power generation device using fluid flow to generate power, in particular to a device for collecting electric energy by utilizing the galloping phenomenon of a cylindrical vibrator group equipped with a rough belt in a lake current or an ocean current. Background technique [0002] At present, energy issues have become a hot spot in the world. The use of traditional fossil energy has led to increasingly serious environmental pollution, and most of the traditional fossil energy is non-renewable energy. The development and utilization of renewable new energy has been highly valued by various countries and has become an important direction for the development of the energy field today. For renewable energy available in the environment, flow energy in the form of wind energy, water currents, and ocean currents is a ubiquitous renewable resource. Among many new energy types, ocean current energy is a clean and renewabl...
