Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

2. Description of the Related Art Conventionally, sprinkler equipment in Japan has been installed in buildings, factories, warehouses and the like having a certain scale according to the Fire Service Law.

[0002] Regardless of the provisions of the Fire Service Law, the simple sprinkler system according to the present invention is to be established as a facility that respects human life by being installed in ordinary houses, apartments, nursing homes, and nursery schools. .

[0003]

2. Description of the Related Art Conventionally, sprinkler facilities in Japan have been installed in accordance with the provisions of the Fire Service Law, but most of the facilities are provided with a water tank as a water source, water is supplied by a pressurized water supply device, and water is sprinkled from a sprinkler head. Put out the fire.

[0004] In the case of a high-rise building such as a building, a pipe is connected to an elevated water tank on the tower floor to obtain a water supply pressure by a head, or a connection water supply port is provided to help the fire brigade to extinguish a fire. .

[0005] However, since the cost of the fire extinguishing equipment as described above is expensive, it is rarely used for small-scale buildings such as ordinary houses, apartments, nursing homes, and nursery schools.

[0006] However, most of the burned-out people in Japan in the event of a fire are often found in the elderly and young children, and the present inventors are concerned about these situations and have filed an application for the present invention. It is determined.

[0007]

SUMMARY OF THE INVENTION According to the present invention, by setting a sprinkler system which exhibits an outstanding effect on fire extinguishing ability at a low price, it is possible to provide a situation which can be installed even in a small building. The purpose is to protect human life that cannot be changed.

[0008]

When installing a sprinkler system, a water tank for securing a water source, a pressurized water supply device for supplying fire-extinguishing water, and a control device for activating the pressurized water supply device are assumed to account for most of the costs. There is a plumbing system that sends pressurized water.

According to the present invention, the water storage tank and the pressurized water are required for fire hydrants and tap water installed outdoors, which are public facilities. Since the pressurized water supply device is not required, control equipment is not required and piping equipment for supplying the pressurized water is required. In addition, small-diameter piping equipment will be sufficient since multiple fires are not considered at the same time.

[0010] In consideration of a local area where public facilities are not provided, a facility using a submersible pump as a pressurized water supply device when groundwater is used as a water source is also defined as a consideration.

[0011]

Embodiment 1 An embodiment will be described with reference to FIG. FIG.
FIG. 4 is a flow chart of a sprinkler facility when pressurized water is obtained from an outdoor fire hydrant, in which a public outdoor fire hydrant main pipe I is branched and a sprinkler main valve K is set in advance.

When it is desired to install sprinkler equipment at an arbitrary location, a check valve R is installed, a sprinkler control valve L is installed, and then a sprinkler main pipe A1 is piped.
Set the drain valve G at the bottom of the sprinkler main pipe A1.

[0013] The check valve is a sprinkler main pipe A1 or A
2 is to prevent the water from flowing back to the public fire hydrant main pipe I, and the drain valve G is set for repairing the check valve R and responding to freezing.

The pipes of the sprinkler main pipe A2 are piped toward the respective guard zones Z, and the sprinkler main pipe A2, the main pipe B, and the branch pipe C are sequentially reduced in diameter. Since fire is not assumed, it does not conform to the pipe diameter based on the Fire Service Law.

The sprinkler piping in the caution zone Z is drawn out to the ceiling surface as a sprinkler branch pipe C when pulled into a necessary place, and when the sprinkler head X is attached, the sprinkler main valve K and the sprinkler control valve L are opened. It is made and water is passed.

When the water is passed, the pressurized water reaches the sprinkler head X, and the pressurized water is maintained in the pressurized state until the fire is confirmed. The sprinkler head X is a shoe valve, and when the temperature rises in the event of a fire, the shoes are melted at a temperature of 72 ° C., and pressurized water is released to spray water and extinguish the fire.

[0017]

Embodiment 2 An embodiment will be described with reference to FIG. FIG.
FIG. 4 is a flow chart of a sprinkler facility when pressurized water is obtained as tap water. The sprinkler control valve L and the check valve R are installed at an arbitrary point from the indoor water pipe E, and the sprinkler pipe is installed in an arbitrary room or place. Pull in.

The drawn-in sprinkler pipe is drawn out to the ceiling surface as a sprinkler branch pipe C, and when the sprinkler head X is attached, the sprinkler control valve L is opened to allow water to flow.

When water is supplied, the pressurized tap water reaches the sprinkler head X, and the pressurized water is maintained in the pressurized state until the fire is confirmed. At the time of a fire, the shoes melt at a temperature of 72 ° C. due to a rise in temperature at the time of the fire, and pressurized water is released to spray water and extinguish the fire.

When a water meter M1 circuit is provided as a dedicated sprinkler path, it goes without saying that a branch from the indoor water pipe E is not required.

[0021]

Embodiment 3 An embodiment will be described with reference to FIG. FIG.
FIG. 4 is a flow chart of a sprinkler facility when pressurized water is obtained from groundwater, taking into account local areas where public facilities are not provided.

In order to use groundwater as a water source, a submersible pump P is installed at the bottom of the well, and pipes for sending pressurized water are designated as sprinkler main pipes A1 and A2. B, the branch pipe C and the diameter gradually become smaller.

A sprinkler control valve L and a check valve R are installed on the sprinkler main pipe B in each of the guard zones Z, and a pressure switch S is set on the sprinkler main pipe B past the check valve R.

The sprinkler main pipe B is drawn into an arbitrary room or place as a sprinkler pipe, and when pulled in, is drawn out to the ceiling surface, and the sprinkler head X is attached.

When the sprinkler head X is attached, the submersible pump P is started manually, and pressurized water is supplied to the sprinkler main pipe A1 and the main pipe B, and the sprinkler control valve L is opened to pass water. The current state is maintained until the fire is confirmed in the pressurized state.

When water is supplied, the pressurized tap water reaches the sprinkler head X, and the pressurized water is maintained in the pressurized state until the fire is confirmed. At the time of a fire, pressurized water is released because the shoes melt at a temperature of 72 ° C. due to the temperature rise at the time of the fire.

When the pressurized water is released, the pressure of the sprinkler main pipe B naturally drops. When the pressure drops below the set pressure of the pressure switch S, a signal is sent through the control wiring T to reach the pump control panel Q. .

Accordingly, although the submersible pump P is started from the pump control panel Q via the pump starting wiring V, the pressure switch S senses the fluctuation of the water supply pressure, and the ON / OFF of the pressure switch S and the submersible pump P is performed. Work together.

[0029]

According to the present invention, most of the people burned to death in the event of a fire in Japan are often found in the elderly or young children, but in order to reduce the number of these victims, general sprinklers with high fire-extinguishing ability must be used. The present inventor considers that the proper installation is urgent.

As shown in the embodiment, when installing the sprinkler equipment, a water tank for securing a water source and a pressurized water supply device for supplying fire-extinguishing water, which account for most of the cost, are greatly reduced.

Further, simplification of the control equipment for activating the pressurized water supply device, and piping equipment for supplying the pressurized water,
Since multiple fires were not considered, the diameter of the piping could be reduced.

Therefore, since sprinkler equipment can be installed at a low price, the sprinkler equipment is also used in small-scale buildings, and equipment for protecting many lives can be widely provided to society.
