Abstract

[PROBLEMS] A large number of people are trapped or laid down in a collapsed house during a huge earthquake and are waiting for rescue. Eventually, when electricity was restored, there was no choice but to watch fires go up and down, fire trucks couldn't come, and they would burn and die. In order to prevent this terrible energizing fire, the government strongly recommends the installation of a seismic breaker. There was a risk of exposure. SOLUTION: Although it is a simple type, a sphere is dropped with a full-scale function and seismic intensity of 5 or higher, the spring timer set in advance is released, and after 3 minutes, the string is pulled and the breaker is dropped. Deformation knob that can be set and returned easily and helps to reduce the size, breaker cap integrated with the string stopper, stop in a bright place after operation, and time extension is possible, so there is no need to set seismic intensity. No work required, simple installation and restoration by one person. [Selection] Figure 1

Description

  Various seismic breakers are being sold as effective for energizing fires in the event of a huge earthquake. The fear of energized fires will be described later. In the event of a huge earthquake, fire trucks will not be able to come, but will still burn. Currently sold are full-fledged built-in distribution boards of 50,000 yen or more, types added to distribution boards that require construction costs, simple types of 3000-4500 yen, 10,000 yen With the above, there is also a partial outlet type effect. Considering the fear of fire spread, dissemination is an absolute requirement, and it is difficult to disseminate it unless it is a simple type price range. However, the simple type has a big shake at night (with a seismic intensity of 5 or more), and the whole house is scattered, suddenly it becomes dark, and there is even the possibility of risking life. Therefore, I was keenly aware of the need for a simple type to drop the breaker after 3 minutes, the same as a full-fledged one.

In the Yomiuri Shimbun on March 10, 2015, an article stating “Prompt installation of a seismic breaker to prevent electric fires in the event of a major earthquake” was published. It is a content to request. Every other media is urging the installation of a seismic breaker with similar articles and television.
In addition to electrical fires caused by large earthquakes, most of the electrical fires that fire when a power failure is restored after a power failure has been restored and the home appliances used have been crushed can be prevented by installing a seismic breaker. The government is planning to encourage this installation. Many houses collapsed due to a huge earthquake, many people were underlayed or confined, electricity restored after a while, fires occurred from various places, fire trucks could not come, no matter how crying I can only watch them die. This is the fear of energizing fire. By the way, 60% of the causes of fires are said to be energized fires in both the Great Hanshin Earthquake and the Great East Japan Earthquake. Even if it is ideal to turn off all the power with a breaker, it is cheap, safe, easy to install even for amateurs, and no products recommended for everyone are currently available.

  The simple type that is on the market scatters in the room when the seismic intensity is over 5 and panics if suddenly it becomes dark, taking out valuables and evacuation equipment, and hindering evacuation with elderly children and sick people There is a risk, and I think that it is a problem that it is being released even though all the governments including the fire department recognize this. Nonetheless, the type with a time lag is similar to the distribution board built in in advance, and it is said that it is difficult except for the new construction, and there is a type that requires additional construction costs and adds to the distribution board. Even if a complete seismic breaker is installed only in a new house with a low probability of collapse, it does not prevent the ugly fire. Furthermore, it is necessary to determine the seismic intensity corresponding to the simple type, but it is impossible for the general public to decide it, even if it is not understood even by an expert unless a huge earthquake actually occurs. There is a possibility that it is too dark and not necessary, but it becomes dark, or it is too strong and does not work when necessary.

  In general fires, many fire trucks come and extinguish the fire, so there is little concern about fire spread. However, there are many fires in a huge earthquake, and the roads are blocked and cannot be relied on at all. Once a fire breaks out, it burns, but no matter how much you protect your home with a perfect seismic breaker, it doesn't make sense to install it unless you consider a flaming fire. For that purpose, it is ideal to set up town units and regional units if possible, but it is essential to spread at least in the target area, and it is strongly desired to install in houses that have not been earthquake-resistant before the new construction. For this purpose, there is a need for products that are equipped with the same functions as the full-fledged type, do not require construction costs, and do not need to determine the corresponding seismic intensity at the same price range as the simple type.

Several types of products that prevent electrical fires are sold and are spread to some extent, but are far from widespread from the whole. If it does not spread, no matter how ideal the product is installed, there is a concern that it will burn out due to an energized fire from a fire that has not been installed. For the above reasons, there are also circumstances where governments are not actively encouraged. It was convinced that the product that can be spread is a product that the general citizens do not need to pay for construction work, and that it can be easily installed even by an amateur and can be purchased without difficulty.
When using batteries, there are concerns about battery problems, and there is a concern that they cannot be used in an emergency. Even if you want to use electricity, there is generally no power outlet where there is a distribution board. You have to pull a cord from another room. Therefore, when the required seismic intensity was felt, the spring was started by dropping the sphere into the hole, and the breaker was dropped 3 minutes later by pulling the string. However, if you just drop the sphere, there was no problem, but it is necessary to attach a string to pull it up at the time of resetting. In addition, another thin string to drop the breaker requires tension, but the breaker switch is easy to fall with a spring, so during installation work alone, another idea is needed to install and reset without pulling the breaker even a little It was. The most troublesome was the idea of making it small enough to be installed on various distribution boards. The larger the size, the more distribution boards that cannot be handled. It is meaningless if it cannot be installed on most distribution boards. Moreover, in families with sick people, elderly people, and small children, you can feel fear just by thinking about the darkness of a huge earthquake, but if you have this, you will have valuables and necessary items in a bright place, let the family in other rooms know, and prepare for evacuation. The possibility of becoming a state can be reduced. Further, as a drawback of the mainspring timer, there is a concern that the spring will be deteriorated when the mainspring is wound, and the time is inaccurate when the mainspring is loosened, and there is a concern that it may stop in the middle if it is considered.
In particular, the simple type seismic breaker needs to determine the corresponding seismic intensity at the time of installation, but even if it is not necessary, it operates in the dark and it does not operate when necessary because it has been decided so There is also the possibility of being wasted.

  In order to detect the vibration, it was considered that the metal ball (16) was most surely dropped by the vibration. In order to easily provide a time lag under the condition that batteries and electricity cannot be used, the mainspring timer (6) must be used. You can lock the spring while winding it, drop the metal ball to unlock it, pull the string at the set time (about 3 minutes), and drop the breaker. Since there is no need for a special power supply, there is no need for batteries or an AC adapter. However, it was impossible for the mainspring to notify the sound that it had been operating for 3 minutes, so as an option for those who thought it was necessary, a space for installing a button battery and a mini buzzer was secured as an option. Even if the batteries are deteriorated, the sound will be reduced or will not sound, and the operation will not be affected. The experiment was repeated to place the sphere on the pedestal (9) to deal with shaking in various directions, and to operate it by dropping it with vibration. If you just drop the sphere without restriction on the size, it would have been necessary to attach a string if you think about resetting, but there is also a space limitation, if the string is entangled or jammed or disturbed There were many cases where it did not fall due to being caught on the way. It must be operated 100% reliably. The reason is that the sphere rolls, and the attachment position of the string is always at the top, and if you slide it down, it won't get tangled. The hole (7) for dropping the sphere after trial and error was made large enough to fit the sphere, and the hanging string was a ball chain (14) with weight. However, if a ball chain stopper for suspending is provided directly above, the ball chain interferes with the falling of the sphere. Therefore, the suspending position is moved to the opposite side of the hole to be dropped, and the wall that receives the sphere with the weight of the ball chain ( 8) The ball chain hangs in a U-shape outside (Fig. 8 left), and it is clear that even if it is a short space, the ball chain can be entangled even in a small space or fall into the hole without being affected by the fall. It was. The ball chain then slides into the hole without difficulty. If this is the case, there is a need for a space for the ball chain to move, and the case must be enlarged accordingly. However, the knob (2) with the ball chain attached is enlarged to provide a cavity inside, so that the ball chain can move. The entire part has been reduced in size, especially the installation space. Furthermore, because I didn't want to disturb the movement of the ball chain on the sphere, an inverted L-shaped convex part (19) is provided on a part of the thin plastic cover that covers the sphere, and a keyhole-shaped notch is provided on the upper part. The ball chain can be easily attached to the sphere simply by inserting the ball chain connection, and it will not move freely. Since a space or wall (8) is provided for temporarily receiving the fall even in a direction different from the hole, the shake from any direction can be dealt with. The wound spring is locked, and a part (10) is provided that is pushed down when the dropped sphere is received to unlock the spring. The middle part of the mainspring 12-minute timer was used for about 3 minutes. In this case, it is usually held in a semi-relaxed state, and the last loose part is not used. The thin string (5) is not pulled halfway, but only the last part is pulled to drop the breaker (see Fig. 9), but the thin string between the main body and the breaker cap needs to be tensioned. At the same time, hold the strap (22) open, pull the cord with another hand (Figure 4 left), and there was no problem with resetting the same thing. It is difficult unless you loosen it. Therefore, the tension of the thin string is kept as it is, and the push spring (20) attached to the thin string is used and the cap is put on while pulling the string, and the workability at the time of resetting is greatly improved. This makes it easy to stop, extend the time, and reset in a bright place. There is no need to determine the corresponding seismic intensity, and if the seismic intensity of about 5 is high, there is a possibility that an energized fire may occur. It becomes correspondence close to the ideal that did not exist.

  To install, stick the main unit to the lower part of the distribution board so that it does not bend with double-sided tape, pick the upper knob, pull it up directly above the left front end of the hole where the knob was fitted, and slowly lower it at that position to make a sphere Rides naturally on the ball seat (Fig. 11). Since the sphere and the hole under the knob are close to each other, you can easily check whether you are on the ball seat. Furthermore, a part of the ball chain was colored (15), and if it was visible, it was used as a guide. Return the ball chain knob to its original position (if the knob is fitted, it will naturally shift from right above the sphere to the right rear) and confirm that the lever is locked down. Push the cord stopper (22) with your finger while holding the switch cap and hold down the switch on the breaker. Pull the tip of the cord with your other hand, and the cord will stretch naturally without any slack. Then it ends. Even if the string is diagonal, it works to some extent.

  However, many people feel resistance to turning off all power with a breaker. For this purpose, we propose a 3P corner outlet that uses six micro switches 3A in parallel instead of the mainspring timer, leaving the part that detects the shaking and dropping the metal ball. If the house simply tilts or collapses, the ball that was holding the switch will rise and the switch will be turned on again. Therefore, we added a function to lock the ball when the switch is turned off. In old houses, there are rare cases where it is not fixed firmly even if it is plugged into an outlet, and there is a concern that this will move, so in that case, it was solved by the proposal of temporarily fixing with double-sided tape. To reset, open the lid on the top, look in from the top, pick the ball chain, confirm that the sphere is on, and close the lid.

  It operates even if there is a power failure because it does not use electricity. No need for construction and easy installation at each location where string tension can be maintained. Even if a huge earthquake occurs at night and the whole house is scattered, even in families with sick and elderly children, it is possible to secure valuables and evacuation equipment with plenty of room in a bright place, and evacuate with family without worrying about panic. The breaker is automatically dropped 3 minutes after shaking with a seismic intensity of 5 or higher. If you don't think you need it, you can stop or reset it, and if you don't think you have enough time, you can extend it halfway, so you don't have to decide the seismic intensity. No matter how much it calls for spread, it is not recommended even for a house that you would like to install and get expensive. Because it is a price range that can be purchased without difficulty by lump-sum purchase at ordinary households or neighborhood associations, it can be spread at once and prevent fire spread in the event of a large earthquake. Furthermore, if you have resistance when dropping the breaker, there is also an outlet type.
