Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an energy conversion device suitable for circulating a magnetic fluid in a closed circuit by using a power machine such as a water turbine as a power source and obtaining electric energy from a magnetic field applied to the magnetic fluid.

[0002]

[Prior art]

 Conventionally, in the field of electric power industry, a steam turbine, a gas turbine, a water turbine, etc. have been used as a prime mover, and a generator etc. have been used as an electric power generation unit to apply the rotational force from the prime mover to the generator, thereby rotating the rotor of the generator. Was used to obtain large capacity power. Therefore, both the prime mover and the generator tended to become extremely large.

[0003]

[Problems to be solved by the device]

 In the electric power industry, as the size of prime movers and generators becomes super-sized, there are many problems such as environmental problems in the installation area and transportation problems for machine parts, etc., and selection of an appropriate installation area is lacking.

Therefore, recently, due to the lack of proper installation areas, a large amount of small-capacity energy has been recovered rather than a super-sized one, and a so-called distributed type energy conversion device has been developed to effectively utilize unused energy. Is desired.

Based on such a background, the present invention aims to disclose an energy conversion device that effectively extracts electric energy by effectively utilizing unused energy.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, this invention circulates a magnetic fluid in a circulation circuit by receiving a rotational force from a power unit arranged in a fluid flow passage and converting fluid energy into a rotational force. A power storage unit is provided which has a power guide unit and an applying unit which is attached to the circulation circuit and applies a magnetic field to the magnetic fluid, and which stores a storage battery for storing electric energy generated from the magnetic fluid.

[0007]

[Action]

 In the above configuration, the rotational force obtained from the power unit is used as the power source of the power guide unit that circulates the magnetic fluid in the circulation circuit, and this rotational force rotates the power guide unit to circulate the magnetic fluid. During this period, a magnetic field is applied from the applying unit to generate electric energy.

[0008] Therefore, when converting mechanical energy into electric energy as in the conventional case, a generator is not required, and therefore, structural simplification and selection of an appropriate installation area are greatly expanded, and it is not used as a distributed type. Energy can be used effectively to obtain electric power.
