Abstract

PROBLEM TO BE SOLVED: To promote active use of water resources economically. SOLUTION: This water tank comprises a first damping water tank 3-1, storing first water receiving a first operation pressure P1 and a second damping water tank 3-2 storing second water receiving the second operation pressure P2. The first water is not mixed to the second water during normal time when at least earthquake or fire does not occur, or the first water is not always mixed to the second water. In the event of fire occurrence, the second water is discharged from the damping water tank 3-2 by the second operation pressure P2 acting to the water surface of the second damping water tank 3-2. As the second water, drinking water is considered as good application. During normal time, two water tanks become independent, and two kind of water volumes are adequately divided particularly, the first water (this water is used only for damping during normal time) has a smaller volume and thus economical. The discharged water power is a pressure of a gas in bomb and is always normal and has an active power without depending on the state of electrical system at the time of earthquake occurrence.

A multifunctional elevated water tank according to the present invention comprises a first vibration damping water tank (3-1) for storing first water and a second vibration damping water tank (3-2) for storing second water. It is configured. The first water does not mix with the second water in non-emergency, and the second water in emergency.
Water is discharged from the second damping water tank (3-2). By separating the first water and the second water, the water used as vibration damping water in an emergency can be effectively used with proper distribution. The first pressure acts on the first water and the second pressure acts on the second water. Such pressure is atmospheric pressure, or
It is a pressure that is actively controlled by calculation. The first pressure is a first design pressure for synchronizing the vibration of the first water with the vibration of the building in an emergency such as an earthquake, and the second pressure is
It is a second design pressure that tunes the vibration of the second water to the same vibration of the building during the emergency. The gas layer of the first damping water tank (3-1) is so arranged that the first pressure matches the second pressure.
It communicates with or separates from the gas layer of the second damping water tank (3-2).

A pressure control valve or valves (8) are preferably added. The pressure control valve (8) can reduce the gas pressure in the cylinder (1) to adjust it to the first design pressure. The pressure control valve (8) is preferably composed of a first pressure control valve and a second pressure control valve (not shown). The first pressure control valve (8) reduces the gas pressure in the cylinder (1) and adjusts it to the first design pressure, and the second pressure control valve reduces the gas pressure in the cylinder (1). Adjust to the second design pressure. By such independent adjustment, optimum parameters can be set for the vibration system regarding the individual water tanks having different water amounts or water levels. The first water is water used only for damping, and the second water is preferably water for daily use.

The surface of the first damping water can be adjusted. The surface of the second damping water can be adjusted independently of the surface of the second damping water. Third damping water tank for storing the third water (3-

The water tank is divided into two during normal times, and the two types of water are appropriately distributed, and the first water (particularly, water that is used only for vibration suppression during normal times) is small and economical. is there.
The drainage force is the pressure of the gas in the cylinder, and is normally active regardless of the state of the electrical system at the time of the earthquake. It is not prohibited to have an electric pump that maintains the pressure inside the cylinder at a constant high pressure during normal times. The second operating pressure may be atmospheric pressure, which has a damping effect.

It is important that a pressure gas cylinder (1) for enclosing the damping gas is added. In this case, the first

BEST MODE FOR CARRYING OUT THE INVENTION Corresponding to the drawings, in an embodiment of a multifunctional elevated water tank according to the present invention, an air cylinder is provided together with a multifunctional elevated water tank. As shown in FIG. 1, the air cylinder 1 is connected to the multifunctional elevated water tank 3 via a main pipe 2. The air cylinder 1 is preferably provided as a high pressure air-tight container that does not necessarily require a compressor. The air cylinder 1 may cause a decrease in internal air pressure for many years.

Pressure switch 4 attached to the air cylinder 1.
Normally monitors the air pressure in the air cylinder 1. The pressure switch 4 converts a decrease in the air pressure in the air cylinder 1 below a specified pressure into a pressure drop monitoring signal 5, and a remote installed by a multi-function elevated water tank manager via various lines / nets 20. The pressure drop monitoring signal 5 is transmitted / reported to the monitoring electronic device 7 of the monitoring center 6 as pressure drop information. Upon receiving the pressure drop monitoring signal 5, the monitoring center 6 causes the supervisor in charge to have the new air cylinder 1 and immediately replaces the old air cylinder 1 with the new air cylinder 1 for replacement. It is important to constantly monitor the air pressure of the air cylinder 1 and the open / closed states of the open / close valves arranged everywhere in preparation for an emergency.

The pressure control valve 8 is provided in the main pipe 2. The pressure control valve 8 mechanically (non-electrically) adjusts to the operating air pressure P in the multifunctional elevated water tank 3 which is the pressure on the downstream side.
In response, the operating air pressure P is maintained / maintained constant.
The instantaneous valve opening / closing operation of the pressure control valve 8 that maintains / maintains the operating air pressure P at a constant level is physically / mechanically automatic and non-electrical. Therefore, the pressure control valve 8 can surely perform the valve opening / closing operation regardless of the operation / non-operation of the electric system at the time of fire, earthquake, or water cutoff.

The normality of such a mechanical operation is regularly inspected by a supervisor in charge. The pressure control valve 8 is a known technique that operates with the downstream pressure as a mechanical feedback signal 9. When the pressure in the air layer 12 exceeds the specified pressure, the air in the air layer 12 can be discharged to the outside via the safety valve 13.

In the multifunctional elevated water tank 3, the lower layer is the water tank or the water layer 11, and the upper layer is the air tank or the air layer 12 at two places. The same pressure in the two separated air layers 12 suppresses the movement of both sides S of the water layer 11 during an earthquake. The air layer 12 is pneumatically equivalent to a spring. The movement period (frequency) of the water layer 11 is determined by the equation of motion described by the pressure P and the volume of the air layer of the water layer. The water vibration becomes equal to the worst-case frequency of the multifunctional elevated water tank 3 at the time of the earthquake and is synchronized, and the vibration of the multifunctional elevated water tank 3, which is the top part of the building structure, is damped by the reaction force of the vibrating water. can do.

The movement of water in the multi-function elevated water tank 3 is formulated by a so-called U-tube vibration model. The parameters of the vibration system whose equation of motion is formulated are the volume of the air layer and the spring constant of the air inside the air above the water surface. An air layer that is a part of the building structure as a reaction force due to the inertial force of the vibration that synchronizes with the frequency of the building structure at the time of the earthquake It acts on the wall and damps its vibration. The spring constant is described by the operating pressure P (pressure change caused by volume change) of the air chamber, which is one of the external forces appearing in the equation of motion.
The frequency can be adjusted by adjusting the operating pressure P. Such operating pressure P can be easily adjusted by mechanical adjustment such as displacement of the mechanical adjustment terminal of the pressure control valve 8 or change of its material.

The main pipe 2 is branched between the air cylinder 1 and the pressure control valve 8 and connected to the sub pipe 14. Sub piping 14
Is connected to the main pipe 2 at a downstream point 30 of the pressure control valve 8. The inside of the air cylinder 1 is communicatively connected to a downstream side point 30 through a cutoff valve 15 and a check valve 16 provided in a part of the main pipe 2 and the sub pipe 14. The check valve 16 is
It is arranged on the downstream side of the shutoff valve 15 in the middle of the auxiliary pipe 14. The check valve 16 has a mechanical check function and allows air (working fluid) to flow from the air cylinder 1 toward the downstream side point 30, but goes from the downstream side point 30 toward the air cylinder 1. Block the flow of air.

The shutoff valve 15 can be opened by an artificial operation command. The artificial command operation is a physical / mechanical external force (arm force) of a monitor in charge of the valve opening / closing handle of the shutoff valve 15, or an input signal manually input by the monitor during an earthquake, fire, or water cutoff. Is an emergency response artificial electrical signal 17 generated by the monitoring (service) center 6 based on The shut-off valve 15 can be opened by an emergency response artificial electric signal 17, and the shut-off valve 15 can be opened by an arm force of an observer or a person in charge of a fire of a building structure. The observer or the person in charge of the fire of the building structure visually confirmed that the shutoff valve 15 was opened by the emergency response artificial electric signal 17, and visually confirmed that the shutoff valve 15 was not opened. In that case, the opening operation of the shutoff valve 15 is forced by one's own force.
