Description

Earthquake-proof plate electronics {The Panel controlling quake-proof plate automatically}

In the event of an earthquake, even if the building itself is sound, even if the building itself is sound, the objects inside the building may fall, internal pick-ups or devices collide with each other, or they may be damaged or fail to function properly. have.

Recently, medical-related facilities, semiconductor-related facilities, computer centers of financial institutions, disaster prevention command centers, and telecommunications companies are lacking in earthquake-proof design of buildings themselves, and internal appliances or devices accommodated within them are not suitable for earthquakes. The most important thing is to be able to maintain its original function even in the event of a disaster.

For example, in high value-added facilities such as semiconductor factories, production management, such as pressure management, cleanliness, temperature control, and humidity control, and the blueprint, an important intellectual property, are controlled and controlled in the central computer room. The building itself is usually earthquake-resistant. However, in the event of an earthquake, even if the damage of the seismic design of the building itself is slight, the large computer or other expensive inspection equipment in the central computer room housed inside it will be damaged due to the earthquake response and damage or damage. Problems often arise that can cause damage or malfunction.

Therefore, aside from the seismic design of the building itself, there is a need for a device that protects expensive equipment or objects contained therein from vibrations generated by an earthquake or the like.

When an earthquake occurs, the shock of the sudden fluctuations causes an earthquake-causing wave. At this time, the wave that causes the earthquake is called seismic waves. There are three types of seismic waves: P waves, S waves, and L waves.

The speed of P wave is 5 ~ 8km / s and it is a longitudinal wave, so it can pass through solid, liquid, and gas, and the land moves up and down while P wave passes. In addition, since the amplitude is smaller than the S wave, the degree of damage is also smaller than that of the S wave.

The speed of S wave is about 4km / s, which is slower than P wave. Since the S wave is a transverse wave, the media particles oscillate at right angles to the direction of propagation, so the ground shakes from side to side while the S wave passes. In addition, the damage is large because of the large amplitude. S-waves propagate only in solids and not in liquids and gases.

L waves are surface waves that propagate along the surface of a solid and are transmitted along the earth's surface without passing through the earth. In general, L waves are slower than P and S waves, and have a larger wavelength and amplitude.

When seismic waves propagate, the faster P waves arrive first, and the slower S waves arrive later. In this case, the initial weak vibration in which only the P wave reaches and the S wave does not reach is called initial fine motion.

When the S wave arrives after the initial slow motion, the seismic waves recorded on the seismograph suddenly increase in amplitude. This time is called main vibration.

Seismograph is commercially available in various forms, and it is a device that records and detects earthquakes.

Acceleration sensor is classified into 1, 2, and 3 axis acceleration sensors and is classified according to how many axes the vibration direction is detected. Means.

The present invention aims to provide a means for effectively damping vibrations such as earthquakes, in order to protect expensive equipment contained therein from conduction or impact even if vibrations (shakes) of buildings occur due to an earthquake or the like.

Various prior arts exist to solve the above problems. However, the present invention not only solves the above problems basically but also has the novelty of further solving the following differentiated technical problems.

1. In general, the equipment is firmly fixed on the floor to ensure stability, but only when an earthquake occurs, it is separated from the floor and responds to seismic isolation.

2. Seismic plate responds to earthquake only when receiving earthquake detection or earthquake occurrence information.

3. Prevent malfunctions of living vibration.

1. Even if the building vibrates (shakes) due to an earthquake, it not only protects the expensive equipment contained therein from conduction or impact, but also the equipment is usually firmly fixed to the floor and stable, but only when an earthquake occurs. Separated from and responded to isolation.

When an external force is applied to the equipment due to carelessness rather than an earthquake, the equipment may move (shake) .In this case, if the cable is not sufficiently connected, the cable may be disconnected or burned. Occurred in the device.

Therefore, it is usually firmly fixed on the floor, but only when an earthquake occurs or more than a certain impact, it is isolated.

In addition, there is a device having its own vibration of the equipment, in the case of such equipment should be firmly fixed to the floor to reduce noise and vibration.

In particular, emergency generators with high vibrations, transformers and uninterruptible power supplies that generate their own vibrations and noises must be firmly fixed to the floor. Existing products can be applied to bearings, rollers, and springs that have a low coefficient of friction when vibration impacts occur. This causes a problem that the amplitude is amplified.

As a main feature of the present invention, it is firmly fixed to the floor in normal times, and has a feature that the coefficient of friction between the upper plate and the lower plate becomes small only when a large impact or an earthquake occurs.

2. Seismic plate responds to earthquake only when receiving earthquake detection or earthquake occurrence information, and is normally fixed to the floor. Receive earthquake alarm generated in disaster situation room, or seismic wave of P wave is detected through acceleration sensor. Only when the seismic coefficient of the seismic plate is reduced, the seismic response is achieved.

3. Distinguish seismic vibrations from earthquakes to minimize malfunctions.

By effectively attenuating the vibration transmitted to expensive equipment or objects placed on the upper plate, it is possible to prevent the fall and impact of expensive equipment or objects even if an earthquake occurs. It is fixed to amplify the shock caused by the equipment's own vibration or shock (less friction coefficient), so that the shaking does not increase, and the friction coefficient between the lower plate and the upper plate becomes small only when an earthquake occurs or when a large shock is applied from the outside. Minimize vibration to the upper plate.

In addition, only when the seismic alarm is received from the disaster situation room or when the seismic wave of the P wave is detected through the seismograph, the friction coefficient of the seismic plate is reduced so that the seismic response only depends on the external environment. Maximized.

In addition, it effectively prevented malfunctions in the living vibration occurring around the equipment.

In the seismic plate for fixing or releasing the upper plate and the lower plate by the fixing means according to whether or not the earthquake occurs, when the seismic wave is generated, the fixing means between the upper plate and the lower plate is released, and when the seismic wave no longer occurs. The main control unit for controlling the fixing means for fixing again, characterized in that it corresponds to distinguishing the living vibration and seismic waves.

The fixing or releasing method by the fixing means between the upper plate and the lower plate may exist in various ways, but the fixing means is not limited in the present invention.

The main feature of the present invention is to distinguish between seismic waves and living vibrations, and to distinguish between vibrations of living and seismic waves, P-waves, and S-waves, thereby fixing / releasing the fixing means to respond to earthquake vibration according to the characteristics of vibration.

As an embodiment, an embodiment of fixing / releasing by fixing means is as follows.

In FIG. 3, after stacking the spring 7 and the supporting plate 8 in the lower plate 2, the ball 6 is placed and the upper plate 1 is covered with air through the air inlet 5 with a vacuum pump. Suction the to make the space 9 between the upper plate 1 and the lower plate 2 into a vacuum state, and then close the solenoid valve 4 to fix the upper plate 1 and the lower plate 2;

When the earthquake is detected by the earthquake sensor, the control unit composed of a microprocessor opens the solenoid valve 4 so that air is sucked into the space 9 between the upper plate 1 and the lower plate 2 to prevent vibration caused by the earthquake. It is possible to vary the seismic response according to the occurrence or absence of earthquakes by buffering the vibration between the upper plate 1 and the lower plate 2 by the spring 7 and the left and right oscillation balls 6. In the seismic design plate, characterized in that the fixing means' vacuum pump 'and' air intake ',' electromagnetic valve 'is fixed by the fixing means by means of the' vacuum pump to suck the air through the air inlet (5) After the space 9 between the upper plate 1 and the lower plate 2 is made in a vacuum state, the solenoid valve 4 is closed to fix the upper plate 1 and the lower plate 2.

That is, as shown in Fig. 4, the space between the upper plate and the lower plate is in a vacuum state, so that the vacuum port is firmly fixed (binding) by several horses, as in the case of Garyke's Magdeburg experiment.

The following describes the differentiation and response of domestic vibration and seismic waves.

The detection means uses a conventionally known seismic acceleration sensor which is variously present as shown in the photograph of FIG.

It is to analyze the amplitude signal of the vibration signal detected by the earthquake acceleration sensor to determine the type of living vibration and seismic wave. In the case of the living vibration, as shown in FIG. Are simultaneously generated and delivered to the equipment 10 at about the same time.

That is, when the above-mentioned vibration is transmitted to the equipment, the distance between the point of occurrence of the vibration and the equipment is so close that up and down vibration (P wave) and left and right vibration (S wave) are simultaneously transmitted to the equipment. Since the vibration is not large, the vibration is not transmitted to the equipment.

Living vibration is not much vibration, but because it is relatively close to the equipment (detection point) is to feel the vibration greatly.

However, in the case of seismic waves, the distance between the epicenter and the equipment (detection point) is long and the vibration is large, resulting in a difference in the transmission speed between the longitudinal wave (P wave) and the transverse wave (S wave).

In the case of seismic waves, the first longitudinal wave (P wave) is propagated on the basis of the above principle, and even if the vibration is not large, the seismic response is made corresponding to the coming wave (S wave). When and when the shear wave (S) is detected at the same time, if the vibration is greater than the reference value is seismic response irrespective of whether or not seismic waves, but below the reference value it characterized in that it does not correspond.

Hereinafter, the claims will be described in detail.
