Description

The present invention relates to a sprinkler facility that uses tap water as a water source.

As a conventional sprinkler equipment for water connection, there is one that configures a sprinkler equipment by connecting a pipe provided with a sprinkler head to a water pipe (for example, see Patent Document 1).

Furthermore, in the above sprinkler equipment, if a fire occurs when water is supplied to the bathtub, etc., a sufficient amount of water may not be sprayed from the sprinkler head. Has been invented (see, for example, Patent Document 2).

Japanese Utility Model Publication No. 48-46500 Japanese Patent No. 2906070 (page 2-3, Fig. 1)

The above-mentioned sprinkler equipment has a shortage of tap water released from the sprinkler head when the sprinkler head is activated in the event of a fire in areas where the supply pressure of tap water is low, such as high altitudes, or areas that are drought in the summer. As a result, the fire extinguishing ability of the sprinkler head may not function sufficiently.

Therefore, in the present invention, in view of the above problems, a water supply connection that can supply water to a water supply sprinkler facility connected to a water supply facility having a low water supply capacity, to a pipe in which a sprinkler head is separately installed from a water source in the event of a fire. The purpose is to provide a sprinkler facility.

In order to achieve the above object, the invention according to claim 1 is a sprinkler facility in which a sprinkler head is installed in a fire extinguishing pipe branched from a water pipe, and water is supplied to the fire extinguishing pipe from the outside. It is a sprinkler facility for water connection that is provided with a possible water supply device.

Invention of Claim 2 is the water supply sprinkler installation of Claim 1 whose water supply apparatus which can supply water to the fire extinguishing pipe from the exterior is a water supply port connected to the fire extinguishing pipe.

The invention according to claim 3 is the water sprinkler facility for water supply according to claim 1, wherein the water supply device capable of supplying water to the fire extinguishing pipe from the outside is a water storage tank connected to the fire extinguishing pipe.

In the invention according to claim 4, the water supply device capable of supplying water to the fire extinguishing pipe from the outside has a water supply port connected to the fire extinguishing pipe and capable of feeding water from the outside to the fire extinguishing pipe. The water sprinkler system for water supply connection according to claim 1, wherein the water channel between the mouth and the fire extinguishing pipe is blocked and water can be passed to the fire extinguishing pipe only when water is sent from the water supply port.

  Even if the amount of water supplied from the water supply is insufficient due to the sprinkler equipment of the present invention installed in buildings in areas with low tap water supply pressure such as high altitudes or areas that are drought in the summer, water is supplied from the outside. Since it can be received, a sufficient amount of water is sprayed from the sprinkler head into the room, and the fire can be suppressed and extinguished.

In water-deficient areas, it is possible to secure a sufficient amount of water for fire extinguishing by supplying water stored in the water storage tank to the fire extinguishing pipe.

The best mode for carrying out the present invention is shown in Example 1. The second embodiment is a form in which the first embodiment is applied.

Embodiment 1 of the present invention will be described below with reference to FIGS. FIG. 1 is a system diagram of the sprinkler facility of the first embodiment, and FIG. 2 is a cross-sectional view of a switching device that switches a water channel between a water supply port and a water pipe.

In the sprinkler facility of FIG. 1, a water pipe 1 is branched into a fire extinguishing pipe 2 and a water tap pipe 3. The fire extinguishing pipe 2 is always filled with water, and a check valve is installed near the branch of the water faucet pipe 3 and the water pipe 1 so that the water in the fire extinguishing pipe 2 does not flow backward. Has been.

A sprinkler head 4 is provided in the middle of the fire extinguishing pipe 2, and a water tap for a toilet tank is provided at the end.

The fire extinguishing pipe 2 is provided with a water supply port 5 capable of supplying water to the fire extinguishing pipe 2 from the outside. The water supply port 5 is connected to the fire extinguishing pipe 2 by a water supply pipe 6. A switching device 7 is provided on the water supply pipe 6 so that water does not flow from the fire-extinguishing pipe 2 side to the water supply port 5.

The switching device 7 shown in FIG. 2 has a plurality of connection ports, and is provided with a water channel switching member 8 for switching the water channel of each connection port, and is slidably installed in the switching device 7. Yes. The connection port is provided with a connection port A connected to the water pipe 1 side, a connection port B connected to the side where the sprinkler head is provided, and a connection port C connected to the water supply port 5.

The water channel switching member 8 inside the switching device 7 has two water channels, and the straight water channel on the right side in the figure is used to allow the connection port A and the connection port B to pass through. The bent water channel on the left side is used for passing the connection port C and the connection port B through.

The water channel switching member 8 is urged toward the water supply port 5 by the projectile 22 and the water channel of the water channel switching member 8 is in a state in which the connection port A and the connection port B can pass water during normal times. C is in an interrupted state.

When a fire occurs and the sprinkler head 4 is activated, water in the fire extinguishing pipe 2 is released from the sprinkler head 4 and water is sprayed into the room. When a fire engine arrives due to a fire report, the water supply port 5 and the fire hose are connected and water is supplied from the fire engine, so that the pressurized water flows into the connection port C, and the pressure of the water is a bullet. Since the urging force of 9 is exceeded, the projectile 9 is compressed and the water channel switching member 8 moves to the projectile 9 side.

Then, the water channel on the left side in the water channel switching member 8 is allowed to pass through the connection port B and the connection port C so that water can be supplied from the water supply port 5 to the fire-extinguishing pipe 2. It is sprayed to suppress and extinguish fires.

A second embodiment will be described with reference to FIG. FIG. 3 is a system diagram of the sprinkler facility of the second embodiment.

In the second embodiment, the difference from the first embodiment is that a water storage tank 10 is provided at a high place instead of the water supply port 5, and the water in the water storage tank 10 can be discharged from the sprinkler head 4. is there.

The water in the water storage tank 10 may store rainwater or supply tap water. The water storage tank 10 is connected by a fire extinguishing pipe 2 and a water supply pipe 11, and a control valve 12 is installed on the water supply pipe 11.

The control valve 12 is closed during normal times. When the sprinkler head 4 is actuated in the event of a fire and the water flow detector 13 installed on the fire extinguishing pipe 2 is actuated, the control valve 12 is opened and the water in the water storage tank 10 is sent to the fire extinguishing pipe 2. .

As an application of the second embodiment, a fire detector may be provided in the vicinity of the sprinkler head 4 in place of the flowing water detector 13, and the control valve 12 may be opened when the fire detector is activated.

It is also possible to combine the sprinkler facilities shown in the above embodiments.

Moreover, in Example 2, it is possible not only to receive water supply from the water tank only at the time of a fire, but also to use the water in the water tank even when using the toilet by keeping the control valve 12 open at all times. is there.
