Description

[Detailed Description of the Invention] Technical Field The present invention relates to a disaster prevention system for underground spaces, more specifically, to effectively utilize underground spaces such as basements of high-rise JFU buildings, underground shopping malls, and subway premises to prevent disasters such as earthquakes. The present invention relates to a disaster prevention system for securing temporary space in the event of a disaster.

Predictions that a major earthquake will occur in the Tokai region in the near future have been reported with a high degree of accuracy, but countermeasures have been slow to make progress, and recently, there has been a rise in land prices. In response to this, the use of deep underground areas is being considered. In addition, underground areas of high-rise buildings, although not very deep,
Subway stations are located at considerable depths, and underground shopping arcades have also become booming recently. Therefore, the underground space is
It is structurally safer than above-ground structures against disasters such as earthquakes, and if this underground space can be used effectively in the event of a disaster, many lives can be saved from the disaster. However, in the event of a disaster, underground spaces are flooded with toxic air containing fire, smoke, and low carbon dioxide gas, which often causes many people to have difficulty breathing or even die. In the event of a disaster, the electrical system may fail, and underground areas in particular become pitch black, increasing fear and causing a state of panic in places where there are a large number of people.

The present invention was made in consideration of the above-mentioned actual situation.
In particular, in the event of a disaster, in addition to replenishing underground spaces with air at a pressure higher than the outside pressure to prevent fire, smoke, and other toxic air from flowing in, private power generation equipment can be effectively activated (normally, Kerosene, heavy oil gasoline, etc. are used to drive a private power generator, but this kerosene or gasoline requires a large amount of oxygen to burn, and unless sufficient oxygen is supplied, the private power generator will not operate. mosquito,
It uses the surrounding oxygen to release carbon monoxide.

On the contrary, it will end up costing people's lives.

Structure FIG. 1 is a block diagram for explaining one embodiment of the present invention. The figure shows an example where the invention is applied to the underground space of a high-rise building. The present invention is not limited to the above, but can be applied to all underground spaces such as subway station premises and underground shopping malls.

In Figure 1, 10 indicates the underground space of a high-rise building, and 1
1 is a spring water tank on the lowest underground floor, 12, 13, 14, etc. are underground parking rooms, and the underground space of the high-rise building is structured as shown in the figure. The spring water tank 11 is where spring water is taken out, but in reality, it is pumped up all the time, so normally there is almost no spring water, and normal people are prohibited from entering and exiting this spring water tank. It is only accessible on special occasions, but as mentioned above, there is almost no oil or water, and in fact, it is always empty.

21 is a compressed air (liquid air) cylinder installed in the spring water tank, 22 is a control box installed in a part of each underground parking lot, and 23 is a private power generation room installed on the upper floor of the basement as possible. be. In the event of an earthquake, there is a risk of buildings collapsing on the ground or a fire breaking out, causing chaos; underground, although there is no danger of the building collapsing, a fire may break out, or there may be fire, smoke, or other sources coming from outside. There is a risk of poisonous gas blowing in or a power outage.Currently, even if you escape underground, you may run out of oxygen, and the darkness around you increases your fear, which can lead to panic, especially if there are many people. There is a risk of falling into. Therefore, in the present invention.

By pressing the emergency button attached to each control box, the valve of the compressed air cylinder opens and blows out compressed air, and the air blown from the compressed cylinder is blown to the ground, thereby preventing external flames and smoke,
It also prevents other toxic air from blowing in, and at the same time maintains clean air inside the underground space.

Also, the exit can be found depending on the direction of air flow. By pressing the aforementioned emergency button, or by pressing another emergency button, the private power generator is activated to turn on the underground lights and provide power to operate the sewage treatment system. Preferably, the control boxes are installed in multiple locations, including each floor underground, a guard room above ground, etc., and when the emergency button of any one control box is pressed, compressed air is blown out. A control program has been set up to operate the private power generation system. Although the illustrated example shows an example in which multiple control boxes are provided, it is easy to understand that it is also possible to have only one control box and install only emergency buttons in multiple locations. .

Also, although Figure 1 shows a single large generator, it is also possible to prepare many generators that use small gasoline engines, and it is possible to prepare many generators that use small gasoline engines. Sometimes, if you drain the gasoline from a car in a parking lot and use it, there is no risk of an explosion, and this is a win-win solution.

Also, if you insert a pipe 24 etc. into the spring water tank, spring water will be sprayed out, but if you install a faucet etc. at the outlet end of this pipe,
Normally, the faucet is closed to prevent water from flowing, but in the event of a disaster, the faucet can be opened to gush out spring water and use it.This solves the problems of air, light, water, and filth. can.

Furthermore, the present applicant first focuses sunlight or artificial light using a lens or the like and introduces it into a light guide cable, transmits it to any desired location through the light guide cable, and at that location, the light guide We proposed the use of light emitted from cables for illumination and other uses, such as photosynthetic light sources in forced cultivation of plants, light sources for fish farming equipment, etc., and actually used it to grow plants in basements, etc., and for fish farming.
