Abstract

PROBLEM TO BE SOLVED: To enable immediate countermeasures by sensing and warning a degree and a direction of a quake when a spherical ball placed on a bottom part of an inverse conical shape enters an outer fence due to the inertia of the quake or reacts and pops up. SOLUTION: A triangular element 4 forming an inverse conical shape 33 is hinged and supported by an adjustment plate 7 to a coupling ring 5. An inclined face of the conical shape is changed by an adjustment screw 8. A spherical ball 6 placed at a central part of the adjustment plate 7 rolls up along the inclined face of the conical shape 33 subsequent to a quake, going beyond an inner cylindrical part 2 when the quake is not smaller than a predetermined degree and coming in pressed touch with a rim conductive plate 9 in the outer circumference of an outer cylindrical part 3. The ball is also in touch with a hinge part into a state 6b. The conductive plate 9 is connected with the ring 5 via the ball 6, whereby conductive wires 31, 30 are electrically connected with each other. On the other hand, the ball 6 popping up due to an up-down quake presses up a contact plate 12, whereby a contact bar 13 is connected with a spring contact 16 and conductive wires 29, 28 are electrically connected. In this manner, the ball 6 works as a switch, a relay through its movement over a predetermined range, so that a battery 27, a buzzer 23 and a lamp 24 are connected to warn.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is based on the fact that meteorological stations measure information on earthquake occurrence with various kinds of sophisticated instruments, and the information is released comprehensively through government agencies and the news media. Accordingly, the present invention relates to a device for knowing approximate information immediately after occurrence with a simple device and enabling an emergency response, since a response after the information is too late.

[0002]

2. Description of the Related Art Conventionally, a meteorological observatory measures various types of sophisticated instruments to measure seismic intensity. Mainly to report the epicenter, etc.
For general household use, the system only detects vibration and issues an alarm.

[0003]

[Problems to be Solved by the Invention] At present, it is common for ordinary households to feel the occurrence of an earthquake by the vibration of their bodies and objects, and then to be informed of the seismic intensity and the epicenter in subsequent reports, and the Due to the presence of a house, it responds to sudden vibrations and wavy earthquakes. There is a tendency for equipment to collapse, so it is necessary to judge urgent precautionary measures and evacuation directions. In addition, it is necessary to wake up immediately when sleeping and to respond, and in the event of a power outage, lighting is also required.

[0004] It is an object of the present invention to provide a warning of an earthquake by voice or lamp light according to the degree and direction of the seismic intensity of the earthquake, and to promptly respond by notifying the approximate direction of the seismic wave. .

[0005]

In order to achieve the above-mentioned object, a simplified earthquake alarm according to the present invention is provided with a spherical ball at the bottom of an inverted conical (polygonal pyramid) shape, and a spherical ball formed by vibration. The degree of seismic intensity using the fact that the ball rolls up on a conical (polygonal cone) inclined surface due to inertia, enters the outer hull, and jumps up by reaction. It detects the tendency of an earthquake and gives an alarm so that an immediate response can be taken.

The magnitude of an earthquake is the width of the earthquake. Shock speed. It is determined based on various factors such as acceleration, and it is widely known that weather stations, etc., publish data based on data measured by various precision instruments. In general, ordinary households need to take immediate action at the time of the occurrence of an earthquake.

In the present invention, although each element of the earthquake is not accurately sensed, it utilizes the inertial force of a spherical ball, and is horizontally placed on the bottom of an inverted cone (polygonal cone). Depending on the degree of the vibration, the retained spherical ball falls over the inclined surface and falls to the outer shell. The switch is pressed by the contact pressure of the spherical ball, or the spherical ball itself is made conductive to establish electrical connection between the electrical contacts. Is connected to generate a buzzer or bell sound, or to turn on a lamp. In the case of vertical movement, the spherical ball is pushed up by the recoil, and the contact provided at the top is pushed up to make the above-mentioned contact. So alert. I try to signal.

In addition, the contour of the inverted conical shape (polygonal pyramid) is divided into a plurality of sections, and once the spherical ball enters one section of the contour, it cannot be moved to another section by the partition wall. In this case, the direction of movement of the spherical ball from its original position, that is, the position before the vibration is known.

From the above, it is possible to know the moving direction of the spherical ball and to estimate the direction of the vibration wave by comparing the direction pointer magnet with the direction pointer magnet, and to detect the vertical vibration if the upper contact is pushed up. As a result, it is possible to quickly respond to the next anticipated quake.

The inverted conical (polygonal pyramid) surface is composed of a combination of a plurality of slightly triangular pieces, and is a kind of polygonal pyramid, and each side portion corresponding to the bottom surface of the polygonal pyramid has a hinge shape. The angle can be changed freely around the connecting ring, and the apex of each triangular piece forming the inverted conical (polygonal pyramid) surface is the upper and lower It is supported by a movable adjustment panel surface, and the inclination angle of each triangular surface can be adjusted by raising and lowering the adjustment panel, so the inertial force when the spherical ball falls over the inclined surface and falls on the outer surface can be adjusted. Therefore, it is only necessary to set a predetermined inclination angle at which an alarm is required.

In the case of vertical vibration, the contact provided on the upper part is pushed up by the vertical movement of the spherical ball and connected to the facing contact to issue an alarm, so that the position of the upper end of the spherical ball and the contact are provided. The position of the contact board that has been adjusted can be adjusted, and an alarm is issued at a predetermined interval.

Since the inverted conical (polygonal cone) portion and the spherical ball must be set horizontally, a level is attached to the frame base holding each portion, and the frame base The top and bottom of the level screw provided at the end is adjusted horizontally according to the level.

[0013] Further, the periphery and the upper surface of the outer wall are covered with a transparent cover so that the spherical ball does not jump out of the outer wall due to vibration.
In addition to making the internal situation visible, a sign indicating the direction is added so that the moving direction of the spherical ball can be understood, so that it can be aligned with the pointer of the direction pointer magnet provided on the frame base. For example, the direction sign and the direction match.
