Abstract

PROBLEM TO BE SOLVED: To store induced electromotive forces generated in coils wound around super-magnetostriction elements by the running loads in a storing means, by providing the super-magnetostriction elements which are respectively positioned below rails and wound with the coils and the storing means which stores the induced electromotive forces generated in the coils. SOLUTION: Holes (a) are bored into a cross-tie 2 below rails 1 and super- magnetostriction elements 4 wound with coils 7 are respectively put in the holes 2 so that the upper ends of the elements 4 may come into contact with the rails 1. Then, one terminals 7a of the coils 7 are connected to the rails 1 and the other terminals 7b are connected to a common line and, further, to a battery. Therefore, when a train 01 runs on the rails 1, the elements 4 are compression-deformed downward by the load of the train 01 through the rails 1 and magnetic fields are generated along the axes of the coils 7 due to reverse magnetostriction effects. As a result, induced electromotive forces are generated in the coils 7 and stored in the battery for future use.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power generator using a railway, a monorail and the like.

[0002]

2. Description of the Related Art There is no prior art related to the present invention.

[0003]

Conventional thermal power generation using petroleum, coal, natural gas or the like as a fuel has a problem of generating harmful gases such as CO ₂ which is a cause of global warming. There is also concern about fuel depletion in the future.

[0004] Further, it is hard to say that the problem of safety in treating industrial waste such as spent fuel has been completely eliminated in conventional nuclear power generation.

[0005] Therefore, the development of a new and economical power generation system using energy, which is clean and free from energy depletion, such as wind and solar thermal energy, which has been neglected in the past, has been promoted.

It is an object of the present invention to provide a power generator along this line.

[0007]

The present invention employs the following means to solve the above-mentioned problems.

[0008] That is, as a power generating device, a giant magnetostrictive element wound with a coil disposed under a rail and a storage means for storing induced electromotive force generated in the coil are provided.

In the above description, when the train runs on the railroad rail, the giant magnetostrictive element is deformed by the load, and a magnetic field is generated along the coil axis by the inverse magnetostrictive effect. As a result, an induced electromotive force is generated in the coil. This electromotive force is stored in storage means. And used.

[0010] In this way, a power generator that can use the energy of a train that has been neglected in the past when the train passes without waste is obtained.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. 1 and 2, a hole a is provided in a sleeper 2 below a rail 1. Then, the giant magnetostrictive element 4 around which the coil 7 is wound is inserted so that the upper end thereof contacts the lower surface of the rail 1.

Each coil 7 has one terminal 7 as shown in FIG.
a is connected to the rail 1 and the other terminal 7b is connected to the common line 6. The common line 6 is connected to a rectifier circuit 8 and further connected to a storage battery 9. Further, these ground wires 5 are connected to the rail 1.

In the above, the train 01 on the railroad rail 1
Travels, the giant magnetostrictive element 4 is compressively deformed downward via the rail 1 by the load, and a magnetic field is generated along the coil axis by the inverse magnetostrictive effect. As a result, an induced electromotive force is generated in the coil 7 as shown in FIG. This electromotive force is rectified by the rectifier circuit 8 and stored in the storage battery 9. And used.

[0014] In this way, a power generation device that uses the energy when the train 01 passes, which has been neglected in the past, without waste is obtained. Therefore, electric energy can be obtained indefinitely as long as the train is running, regardless of the weather.

[0015]

As described above, the present invention uses a coiled giant magnetostrictive element and a storage means disposed under a rail. Then, the induced electromotive force generated in the coil on the giant magnetostrictive element due to the running load is stored in the storage means.

In this manner, the energy due to the traveling load, which has been neglected in the past, can be accumulated and used without waste.
