Technical Field

The invention relates to a liquid metal magnetofluid wind driven generator, and belongs to the technical field of wind driven generators.

Background

At present, common wind driven generators are mainly 2MW wind driven generators, and with the development of situations, wind driven generators with higher power are increasingly popular in the market.

The 2MW wind driven generator has the failure rate of over 20% according to statistics because the speed changer is unreliable, and if a model with higher power is adopted, the failure rate is higher. Therefore, the hydraulic transmission is thought to replace a gear speed change mechanism, but the flow resistance of the hydraulic transmission is large, the power of the hydraulic transmission is difficult to reach thousands of KW according to data, and the power exceeding thousands of KW is difficult to reach, so that a unit without large power still exists up to now.

In order to overcome the problems, the direct-drive high-power wind power generation testing machine is also available in various places, the diameter of a rotor of a 10MW wind power generation machine reaches 10 meters surprisingly, the weight of the machine also reaches hundreds of tons, and therefore, the manufacturing difficulty is huge, and the development of a high-power wind power generator is greatly restricted due to the extremely low rotating speed (only about 10 revolutions per minute) and low efficiency.

Disclosure of Invention

The purpose of the invention is: the wind driven generator is high in power, high in efficiency, simple in structure and small in size.

The purpose of the invention is realized as follows: the wind machine drives the low-speed large-discharge liquid metal magnetofluid pump which takes the liquid metal magnetofluid as a working medium to work, and the high-pressure liquid metal magnetofluid flows through the liquid metal magnetofluid generator again to generate electricity.

The liquid metal magnetofluid pump is a pressure input type inner curve manufactured by stainless steel and is a liquid metal magnetofluid pump with radial plungers.

The liquid metal magnetohydrodynamic generator is an anti-creeping gear motor type liquid metal magnetohydrodynamic generator.

The liquid metal magnetic fluid is a potassium-sodium alloy magnetic fluid.

The invention is characterized in that: high power, high efficiency, low cost and simple structure.
