伝わる振動を低減するようになっている。Conventionally, as this type of vibration prevention device, for example, the one shown in No. 5- is known. This device has a compressor 19
A mounting bolt 17 is erected on the floor plate 16" supporting the floor plate 16", and a lower rubber disc 31. The two-part rubber disc 33 of the spring 32° is sequentially fitted onto the outer circumference of the compressor 19, and the legs 20 are inserted through the mounting holes 20a of the legs 20, which are provided at equal intervals on the outer periphery of the lower surface of the compressor 19. A nut 21 is screwed onto the tip of a bolt 17, and the compressor 19 is supported by a spring 32 compressed by the nut 2I via upper and lower rubber discs 33,31. Alternatively, as shown on the right side of the figure, the mounting bolts 17 on the floor plate 16 are inserted through the mounting holes 20a of the cylindrical vibration-absorbing rubber body 34 and the leg portions 20, and the nuts 21 are screwed in the same manner. The compressor 19 is supported by a vibration absorbing rubber body 34. The spring 32 or the vibration-absorbing rubber body 34 absorbs vibrations caused by the operation of the compressor 19, thereby reducing vibrations transmitted to the floorboard 16.

, 33 and the spring 32 or the vibration-absorbing rubber body 34 to absorb the vibrations of the compressor 19. Therefore, the vibrations of the compressor 19 are absorbed by so-called passive members such as the spring 32 or the vibration-absorbing rubber body 34. If the passive member is designed to be compatible with vibrations, it will not be able to fully absorb high frequency vibrations. As a result, high-frequency vibrations are transmitted to the floor plate 16, and repeated stress is applied to pipes and the like attached to the compressor I9, resulting in damage to the equipment and, as a result, a drawback that it becomes inoperable. Therefore, an object of the present invention is to provide a new support means consisting of a permanent magnet and a coil between the bottom of a vibrating body such as a compressor and the floor, and to synchronize the movement of the support means with the vibration of the vibrating body, thereby vibrating the floor. To provide a vibration prevention device that does not transmit vibration and cause no damage to attached equipment of a vibrating body.

伝わる振動が低減ずろ。The vibrating body during vibration is mainly supported by the interaction between the energized coil of the magnetic cylinder and the permanent magnet, and is hardly supported by the spring. The current applied to the coil is controlled in synchronization with the displacement of the vibrating body. In other words, the vibrating body is supported indirectly by the electromagnet of the immovable main coil, which is fixed on the floor, rather than by elastic rubber or springs that are fixed on the floor as in the past. Therefore, the vibration transmitted from the vibrating body to the floor will be reduced.

なお、本発明が図示の実施例に限られないのはいうまで
もない。Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments. FIG. 1 is a perspective view showing an embodiment of the vibration prevention device of the present invention.
While fixing bolts 17.17 upright on the floor plate 16 with nuts +8.18, the bolts 5 protruding from the movable part 4 of the magnetic cylinder l are attached to the legs 20 of the compressor 19 as a vibrating body. It is inserted into the hole 20a and fixed with a nut 2I. As shown in FIG. 2, the stationary part 2 of the magnetic cylinder 1 consists of a cylindrical main coil 6 fixed to a fixed base 3 and a sensor coil 7 with a small number of turns concentrically arranged on the lower surface of the main coil 6. The movable part 4 includes a main coil 6
A cylindrical permanent magnet 8 having approximately the same height is fitted inside the magnet so as to be able to move up and down, and a collar portion 9 is provided sequentially on two sides of the permanent magnet 8. Consists of rubber disk IO and Porto 5. And Figure 3 (a
), the compressor 1 is attached to the rubber disc 10J of the movable part 4.
Place the legs 20 of 9, and attach the brim 21 a (;
At the same time, springs 11 are installed between the lower surface of the permanent magnet 8 of the movable part 4 and the upper surface of the fixed base 3 of the stationary part 2, with both ends fixed to the lower and upper surfaces of the compressor I9.
A permanent magnet 8 integrated with the main coil 6 is supported at a position that corresponds to the main coil 6 when no current is applied. The spring 11 has a natural frequency of, for example, 1 to 2H2, and the frequency of the compressor I9 is, for example, 60Hz, which is much lower.
It hardly responds to the vibrations of the compressor. The sensor coil 7 is wound in the same direction as the main coil 6, and is connected to a power supply device 14 via a lead wire 12 and a connector +3 (see FIG. 1). The power supply device 14 amplifies the current signal induced in the sensor coil 7 by electromagnetic induction (Lenz's law) by a permanent magnet 8 that vibrates together with the compressor I9, and sends the amplified current to the connector +3 (see Fig. 1). ) and the lead wire 15 from the terminal end 6b (see FIG. 4(a)) of the main coil 6 to the starting end 6a.
It is designed to be supplied in the opposite direction. Therefore,
As shown in FIG. 4(a), for example, a permanent magnet 8 (having magnetic lines of force as shown in FIG. 4(b)) integrated with the compressor 19,
When the sensor coil 7 descends against the spring +1 as shown by the arrow, the south pole approaches and the magnetic flux of the sensor coil 7 decreases, and a current is induced in a direction that prevents this decrease, that is, in the direction of arrow B, according to Lenz's law. Then, the induced current flows into the power supply device 14.
The current is amplified and supplied to the main coil 6 in the opposite direction as shown by arrow C, and this current causes a force in the same direction as arrow A to act on the permanent magnet 8 from the main coil 6. On the contrary, permanent magnet 8
When , the main coil 6 similarly acts on the permanent magnet 8 in the upward direction. The operation of the vibration prevention device having the above configuration will be described next. When the compressor 19 is not operating and is not vibrating, the permanent magnet 8, which is integrally fixed to the leg 20 at the lower end of the compressor 19, is moved by the lower spring I+, as shown in FIG. 3(a). It is supported and stationary at a position corresponding to the main coil 6 on the floor plate +6J2. Therefore, no current signal due to electromagnetic induction of the vibrating permanent magnet is induced in the sensor coil 7, and the permanent magnet 8 and the compressor 19 remain stationary. Next, when the compressor 19 is operated and begins to vibrate downward at a frequency of about 60 Hz, the permanent magnet 8 that is integral with the leg 20 vibrates in a sine wave shape as shown by curve A in FIG. 3(b). ”Move down two times. At this time, if there were no surrounding main coil 6 and sensor coil 7, the sinusoidal vertical movement of the permanent magnet 8 would be caused by the spring 11, which has a much lower natural frequency and hardly responds. The force is transmitted to the floor plate 16 and acts on the floor plate I6 to raise and push down the floor surface in response to the -1 downward movement. However, in reality, a current is induced in the sensor coil 7 by electromagnetic induction (Lenz's law) caused by the permanent magnet 8 vibrating in a sinusoidal manner, and the induced current signal is amplified by the power supply device I4, as described above. is supplied to the main coil 6 so as to drive the permanent magnet 8 in the same direction as its vibration direction. Therefore, a force is applied to the permanent magnet 8 from the main coil 6 in synchronization with the downward movement of the permanent magnet 8, that is, a force as shown in curve B having the same waveform and approximately the same phase as the curve in FIG. 3(b) is applied to the compressor. 19
is mainly supported by this force, and the spring 11
can hardly be supported by the force of In other words, the compressor 19
is supported indirectly by the immovable main coil 6 fixed on the floor, rather than by the spring 32 and vibration absorbing rubber body 34 which are fixed to the floorboard 16'' and expand and contract as in the conventional case (see Fig. 5). . Therefore, the sensor coil 7. is attached to the floor plate 16 as shown by curve C in FIG. Power supply device 14. Only the vibration of a slight deviation due to the signal delay of the feedback system consisting of the main coil 6 is transmitted, and the floor plate 16
almost no longer vibrates. As described above, in the present invention including the above embodiments, the vertical movement of the permanent magnet 8, which vibrates integrally with the compressor 19, which is a vibrating body, is detected as a current signal by the sensor coil 7, and this detection signal is transmitted to the power supply device. 14 and supplies it to the main coil 6 fixed on the floor plate 16, and gives force from the main coil 6 to the permanent magnet 8 in synchronization with the vibration of the main coil 6 fixed on the floor plate 16. Since it is indirectly supported by electromagnetic force, the vibrations transmitted to the floorboard can be significantly reduced compared to conventional vibration-proofing means such as simple rubber or springs, and it has a remarkable effect as a new vibration-proofing means. It goes without saying that the present invention is not limited to the illustrated embodiment.

A supporting coil spring is arranged to control the current flowing through the coil of the magnetic cylinder in synchronization with the displacement of the vibrating body. By indirectly supporting the floor with force, it is possible to significantly reduce the vibrations that would otherwise be transmitted to the floor via elastic rubber and springs.
