Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is installed in a vibrating part such as a train, an automobile, a ship, and a factory power, and vibrates a magnet or a coil through a spring to cut out magnetic flux by vibrating motion to efficiently extract electromotive force. It relates to the device.

[0002]

[Prior Art]

 It is well known by the law of electromagnetic induction that an electromotive force is generated when a conductor cuts a magnetic flux. A generator uses this law to make a static magnetic field or a static conductor correspond to a rotating conductor or magnetic field by moisture or steam force, and uses an electromotive force generated by the conductor cutting off a magnetic flux. Whereas the conventional generator has a structure in which the conductor cuts the magnetic flux by the rotary motion, the power generator of the present invention tries to extract the electromotive force by cutting the magnetic flux by the vibration motion.

[0003] Conventionally, JP-A-49-132505 discloses an inductor adapted to be directly driven by a power stroke in an operating cycle of an internal combustion engine, and an inductor adapted to counteract the power stroke and continue the inductor. An internal combustion engine type power plant is disclosed which comprises a spring structure for generating electricity by vibrating at a frequency of mechanical resonance during a power stroke. Further, in Japanese Patent Laid-Open No. 55-32484, an engine piston is provided at one end of the connecting rod, and an urging force for urging the piston in the compression direction is applied to the connecting rod. The urging force gives a reciprocating motion to the connecting rod, and the permanent magnets attached to the connecting rod are used as the magnetic poles of the generator to increase / decrease the magnetic flux that cuts the armature coil periodically, thereby generating electromotive force in the coil. There is disclosed a power generation device that is induced.

Further, Japanese Laid-Open Patent Publication No. 57-75559 discloses an electric generator in which the tilt of a pendulum caused by a wave is transmitted to a vertically movable mechanism by the lever principle to move a magnet up and down between coils to cut a magnetic field. Is listed. In Japanese Utility Model Laid-Open No. 58-67980, a cylindrical rolling element having a plurality of permanent magnets fitted on its outer periphery is rolled and reciprocated between coils by tilting due to waves, thereby generating electric power. A wave power generator is described. Japanese Patent Application Laid-Open No. 55-160967 describes a power generator in which a drifting floating body is caused to move up and down by a wave, and a coil is moved up and down between magnets to generate power.

[Problems to be solved by the device]

 However, the power generators described in JP-A-49-132505 and JP-A-55-32484 are both installed on the piston of the engine, and the piston back and forth movement and the accompanying spring cause Resonant motion changes the magnetic field. Therefore, the energy required to be taken out as electric energy is the energy of the fuel, and there is the disadvantage that it is necessary to supply the fuel as much as the energy taken out as electricity. Ground vehicles such as trains, automobiles, and bicycles always experience energy loss due to vibration. This is not only an energy loss, but also a source of noise pollution. These energy losses are estimated to be enormous, and their recovery is extremely meaningful.

Further, all of the power generation devices described in Japanese Patent Laid-Open No. 57-75559, Japanese Utility Model Laid-Open No. 58-67980, and Japanese Patent Laid-Open No. 55-160967 disclose energy called waves existing in nature. The present invention is intended to be effectively used and is different from the present invention. A spring is used in the devices described in these publications, but this spring serves as a member for pressing a member and a cushion for the member, and transmits vibration as in the present invention. Not a thing.

As is generally well known, the electromotive force is proportional to the number of turns of the winding, the speed at which the winding moves to cut the magnetic field, and the strength of the magnetic field. However, in any of the cases, the power generators described in these publications cannot efficiently collect energy.

The present invention has been made in view of the above points. Energy of artificial or accidental intermittent or continuous vibration is efficiently converted directly into electric energy and stored. It is an object of the present invention to provide a power generation device that can be effectively used for the above purpose.

[Means for Solving the Problems]

 In order to achieve the above object, as shown in the drawings, the power generator of the present invention includes a plurality of magnets 3 and 4, a plurality of coils 2 sandwiched by the magnets, and a magnet and a coil. It is composed of a spring 10 for vibrating and a device body 1 for accommodating the magnet, the coil and the spring, and the coil 2 or the magnets 3, 4 are arranged so that the external vibration is transmitted from the spring 10 to cut the magnetic flux at a right angle. It is characterized in that it is fixed to No. 1 and a magnet or coil is vibrated via a spring 10. In the present invention, the coil group may be fixed to the apparatus body to vibrate the magnet group, or the magnet group may be fixed to the apparatus body to vibrate the coil group.

The present invention completely recovers the energy released as a loss. When trying to do something for a certain purpose, it is necessary to inject energy from the outside (so-called external force is applied), but all the injected energy does not change to a goal-achieving job. A considerable amount of energy is always released as loss in this process. It is usually emitted as vibration, heat or light. "Energy released completely as loss" here refers to the injected excess energy released in the above-mentioned purposeful action. It does not refer to natural energy such as waves and winds that are scattered in nature.

The configuration of the present invention will be described below with reference to the drawings. Each of the drawings shows an example in which the coil group is fixed to the apparatus body and the magnet group is vibrated. That is, a plurality of coils are fixed at regular intervals in the main body of the apparatus, a magnet is movably arranged in the gap between the coils, and the magnet and the coil are relatively vibrated between one end of the magnet and the main body of the apparatus. It shows a power generator equipped with a spring to allow it. FIG. 1 schematically shows an example of the power generator of the present invention, and FIG. 2 shows the counter magnet plate and the coil in FIG. A plurality of (4 in FIG. 1) coils 2 are fixed in the apparatus main body 1 at regular intervals on the side wall of the apparatus main body, and in the gap between these coils, two upper and lower plate magnets 3 and 4, as shown in FIG. Is fixed so as to reverse the direction of the magnetic flux via a spacer 5 (hereinafter, referred to as a magnet plate 6) so as to be movable. That is, the coil 2 is arranged so as to simultaneously cut the opposite magnetic fluxes of the upper and lower magnets at right angles, and the pair of magnet plates 6 and the coil 2 are arranged so as to have a slight gap. Then, the lower end of the anti-magnet plate 6 is fixed to the flat plate 8 through the fixing member 7, and the coil 2 is fixed to the apparatus main body wall to be integrated. When the spring 10 is inserted between the flat plate 8 at the center where the anti-magnet plate 6 is fixed and the bottom wall of the main body of the apparatus, and the main body 1 of the apparatus is placed in an external environment where it vibrates intermittently as shown in FIG. The energy is absorbed by the spring 10 and causes the pair of magnet plates to vibrate relative to the coil group at the natural frequency of the spring 10 as shown in FIG.

FIG. 3 shows a connection diagram of a power storage device provided with the full-wave rectifier 11. In FIG. 3, reference numeral 12 is a smoothing capacitor, 13a, 13b and 13c are reverse current stopping diodes, 14a, 14b and 14c are current matching devices, and 15a, 15b and 15c are chargers. Before passing through the rectifying / smoothing portion, the series of irregular damping vibration waveforms is as shown in FIG. 6 at the point OO ′ after passing through the rectifying / smoothing portion, and has a pulsating flow with a considerably strong peak value. Become. As a method of storing such a pulsating current, for example, as shown in the power storage device section of FIG. 3, several charging groups are provided, and a low voltage and large current type, a high voltage and small current type are suitable. By arranging them, it is possible to effectively use the generated electric energy. The electromotive force thus generated in the coil is connected to the coil in series or in parallel and taken out to the terminal.

In the embodiment of the present invention described later, a plate-shaped ferrite magnet is used, but by using a magnet having a higher magnetic flux density, it is possible to expect a larger electromotive force to be generated. Also, by using a thin plate-shaped magnet, and by using a large number, it is possible to insert a larger number of coils into the gap, thereby increasing electromotive force. The coil is inserted between the pair of magnet plates, and it is required to be thin in order to prevent an increase in magnetic resistance. On the other hand, if the number of turns is increased, the electromotive force can be increased, but it becomes difficult to take out the current because the internal resistance is increased, and if the wire diameter is increased, the resistance is reduced, but the number of turns is limited. It is impossible to expect sufficient electromotive force.

[0013]

[Action]

 When the spring 10 is inserted between the flat plate to which the magnets 3 and 4 are fixed and the bottom wall of the apparatus main body 1, and the apparatus main body 1 is placed at a place where it vibrates intermittently, the vibration energy is absorbed by the spring and the panel 10 is moved. The magnets 3 and 4 are vibrated relatively to the coil 2 via the power to generate electric power.

【Example】

 7 and 8 show an embodiment of the present invention. In this example, in order to reduce the resistance of the magnetic circuit, prismatic mild steel pieces 16 (8 pieces) are inserted at the four corners. These mild steel pieces 16 (8 pieces) are fixed in the center at the same time as the magnetic resistance is lowered, thereby increasing the weight of the integrated magnet plate group and also serving to absorb the vibration energy of the outside world. Specifically, for example, two 18.5 × 10 × 4 mm plate-shaped ferrite magnets 3a and 4a (maximum magnetic flux density of 3000 to 4000 gauss) are paired and bonded via a thermosetting resin plate (spacer 5a). The counter magnet plate 6a is made. This magnet plate 6a is arranged in a plurality of plates (16 in FIG. 7) at regular intervals (for example, 8 mm intervals) along the wall inside the device body 1 as shown in FIGS. 7 and 8, and the brass arms 17 are arranged. It is fixed to the central support plate 18 via the. Further, another pair of magnet plates 6a are bonded and arranged on the square columnar mild steel pieces 16 at the four corners. The four corners are also fixed to the central support plate 18 via a thick brass rod 20 and adjusted so that the intervals between all the magnet plates 6a are constant (8 mm in this example). .. On the other hand, as the coil 2, for example, an enameled copper wire having a diameter of 0.32 mm is wound 450 times and made to have a thickness of 45 mm.

The coil 2 thus formed in a thin plate shape is inserted between the pair of magnet plates 6a, and the coil 2 is fixed to the apparatus main body wall. The gap between the magnet plate 6a and the coil 2 was about 15 mm in this example. Four leaf springs 10a are inserted between the square mild steel pieces 16 at the four corners and the apparatus main body bottom wall so as to support the pair of magnet plates. The lower part of the square-shaped mild steel piece 16 and the leaf spring 10a, the leaf spring 10a and the bottom wall of the main body of the device are fixed, and the gap between the pair of magnet plates and the coil group can be kept constant against vibration of lateral swing. It must be designed as shown in Fig.8, and the two purposes of installing the leaf spring 10a as shown in Fig.8, transmitting the vibration with a guide in the center and maintaining the gap are satisfied at the same time. be able to. All individual coil terminals were connected in series as output terminals. This made it possible to construct a box-shaped vibration power generator with a side length of 136 mm and a height of 60 mm.

The vibration power generation device prototyped in the above example was installed in the trunk at the rear of the passenger car and fixed to the floor. The irregular wave from the output terminal was connected to the voltmeter and current meter with the rectifying and smoothing section in Fig. 3. As a result of the running power generation test, it showed an average of 3V and 15mA on a normal asphalt pavement at a speed of 60km / hr. It has been found that if this vibration power generator is used as one unit and a large number of units are connected in series or in parallel, the vibration energy lost as larger power can be recovered.

It consists of a device that operates externally and is made to vibrate a magnet or coil to transmit external vibration from a spring to cut a magnetic flux at a right angle. It has the excellent effect of being able to convert and recover body energy loss into electric energy. Not only that, it can also be installed in high-vibration parts such as ships and factory power to convert vibrations into electric energy and to mitigate the damage of vibrations to that extent.

Further, noise and vibration are reduced by the converted electric energy. There are many noise and vibration generators such as moving cars and trains, factories, highways, and iron bridges, and the device of the present invention can be installed at the location where the vibration and noise generator has the largest amplitude as necessary. By installing any number of them, and by installing the device of the present invention, which has been enlarged in size as necessary, the recovery of loss energy is performed with the reduction of vibration and noise.
