Abstract

PROBLEM TO BE SOLVED: To utilize water left in a receiving tank effectively at the time of a disaster by sensing the quakes of an earthquake by a quake detector installed to a building structure and stopping the supply of water through a pump or a feed valve by a controller. SOLUTION: When an earthquake is generated, a quake detector 20 senses quakes, a signal is transmitted to a controller 23 through an electric circuit 24 from the quake detector 20 when the quakes exceed predetermined quake intensity, and the operation of a pump 10 is stopped. Each faucet 7 is closed manually, and the low-pressure water supply operation of the pump 10 is started by the controller 23. When a flow meter 21 senses a flow rate at that time, leakage at any place in a distributing pipe 12 is considered because all of the faucets 7 are closed. The pump 10 is stopped at that time, and the place of leakage is repaired temporarily. Accordingly, leakage from the place of damage and a secondary disaster with the leakage can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building structure having a water leakage prevention / water saving system for preventing water leakage from a water supply facility and saving water in the building structure.

[0002]

2. Description of the Related Art In general, a water supply system in a building structure is configured such that in the case of a low-rise building structure on the first and second floors, water is distributed by water pressure from a water supply main pipe. In the case of a building structure having a higher floor than that, the water pressure from a water pump or an elevated water tank provided for each building structure is used.

FIGS. 5 (a) and 5 (b) schematically show an outline of a water supply facility in a building having a high floor. In the figure, reference numeral 1 denotes a building structure, and 2 denotes a water receiving tank provided in the building structure 1. The receiving tank 2 is provided with an emergency water supply port 3 and an emergency water sampling port 4,
Water is supplied from the water supply main pipe 5 through a water distribution pipe 6 in which a flexible joint 6a is interposed. Reference numeral 7 denotes a water tap installed on each floor. Reference numeral 8 denotes a private power generator installed in the building structure 1, which plays a role of driving the pump 10 through the electric wiring 9 when the power is stopped.

[0004] The water supplied from the water supply main pipe 5 is temporarily stored in the water receiving tank 2 and supplied to the water faucet 7. As a water supply method in this case, FIG. In the example described above, a pressurized water supply method using a pump 10 is used, and in the example shown in FIG. 2B, a gravity type water supply method using an elevated water tank 11 is used. That is, in (a), the water stored in the water receiving tank 2 passes through the water distribution pipe 12, is pressurized by the pump 10 interposed therebetween, and is supplied to the water tap 7. In (b), the water in the water receiving tank 2 is pumped to the elevated water tank 11 through the valve 13 by the pump 10 provided in the middle of the water distribution pipe 12, and from there, the water supply valve 14 and the water distribution valve 14 are actuated by gravity. The water is supplied to the water tap 7 through the water pipe 15.

[0005]

When a building having a water supply system as described above is damaged by a disaster such as an earthquake or the like, the building is stored in the building when the lifeline is shut down due to damage to pipes and the like. There is a concern that precious water will be wasted and secondary disasters due to water leakage will occur. However, conventionally, there has not been provided a system for ensuring the safety of water supply equipment in a building structure in the event of a disaster. Therefore, in fact, various damages have been caused by the damage of the water distribution pipe due to the earthquake.

[0006] When a water pipe in a building structure is damaged by an earthquake, the water supply in an urban area is usually damaged at the same time. In such a case, it is considered that the supply of water from the outside by the water supply to the building structure is simultaneously stopped. In the event of a disaster, the power supply is usually restored before the water supply is restored, and the building structures of a certain size or more are often provided with a private power generator. As a result, electricity is supplied to the water pump before the water supply is restored, causing not only leakage, but also water, which is valuable in the event of a disaster, is dissipated despite being stored in the receiving tank. In some cases, such a problem may occur. In addition, even if stored water remains in the receiving tank, it is needless to say that this water should be used as conservatively as possible during a disaster.

[0007] In view of the above circumstances, in a building structure having a water leakage prevention / water saving system of the present invention, at the time of a disaster, water leakage due to breakage of water distribution pipes and secondary disasters are prevented and water is saved. It is an object of the present invention to provide a building structure having a water leakage prevention / water saving system that can effectively use water left in a water receiving tank.

[0008]

Means for Solving the Problems In a building structure having a water leakage prevention / water saving system according to the present invention, the following means are employed in order to solve the above problems. That is, the building structure having the water leakage prevention / water saving system according to claim 1 is a building structure having a piping facility for supplying water, and a swing detector for sensing a shaking caused by an earthquake, and the piping facility. And a control device that controls supply or stop of water through the pump or the water supply valve based on an output of the swing detector.

In a building structure having this water leakage prevention / water saving system, during an earthquake, a shaking detector provided in the building structure senses the shaking of the earthquake, and a control device interlocked with the shaking detector instantaneously operates. Turn off the water supply through the pump or water supply valve. This has the effect of preventing water leakage due to water pipe damage.

[0010] A building structure having the water leakage prevention / water saving system according to claim 2 is the building structure having the water leakage prevention / water saving system according to claim 1, and a control device for controlling water supply pressure; A flow meter for displaying a flow rate in the piping equipment is provided.

[0011] The building structure having this water leakage prevention and water saving system, with each water tap closed after a disaster,
By operating the control device, a water pressure is applied to the inside of the piping facility, and at the same time, a flow rate in the piping facility is inspected by a flow meter interposed in the piping facility, so that a leak point is formed in the piping facility. Determine if there is. Further, when the supply of water from the outside by the water supply is stopped during a disaster, the control device restricts the water supply pressure, so that the water remaining in the water receiving tank can be used while being saved. . At the same time, by monitoring the flow rate with the flow meter, the remaining water can be systematically used.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an embodiment of the present invention. In the drawing, the same reference numerals as those in FIG. 5A are used for structures or devices similar to those in the conventional example shown in FIG. It is attached. Further, reference numeral 20 denotes a shake detector, 21
Is a flow meter interposed in the water distribution pipe 12, 22 is a pressure sensor for measuring the water supply pressure in the water distribution pipe 12, and 23 is a control device for controlling the operation of the pump 10. The control device 23 is connected to the swing detector 20 by an electric circuit 24, controls the supply and stop of water through the pump 10 based on an output from the swing detector 20, and is also connected to the pressure sensor 22 in the same manner. It also has a role of controlling the water supply pressure in the water distribution pipe 12. Further, the control device 23 is similarly connected to the flow meter 21 so as to control the operation of the pump 10 while monitoring the flow rate in the water distribution pipe 12.

The configuration of the present embodiment has been described above. Next, the function and operation of the water leakage prevention / water saving system according to the present embodiment will be described with reference to the flowchart shown in FIG. The flowchart shown in FIG. 2 is roughly divided into three blocks based on the operation of the water leakage prevention / water saving system. First, in the first block B1, immediately after the occurrence of the earthquake, it is checked whether or not there is a water leakage point in the piping equipment installed in the building structure 1, and the water leakage is prevented. Next, in the second block B2, the water left in the water receiving tank 2 is saved and used until the public water supply (hereinafter referred to as city water) is restored. In the third block B3, before the city water is restored and normal water supply from the water supply main pipe 5 to the water faucet 7 is started, a re-check of the water leakage location is performed. Hereinafter, the content will be described for each block.

First, in block B1 (steps S1 to S6), when an earthquake occurs, the shake detector 2
0 senses the sway, and if the sway exceeds a predetermined sway intensity, a signal is sent from the sway detector 20 to the control device 23 via the electric line 24 and the pump 10
Is stopped (step S1). Next, the water tap 7 is manually closed (step S2), and then the low pressure water supply operation of the pump 10 is started by the control device 23 (step S3). At this time, if the flow meter 21 detects the flow rate, it is considered that there is water leakage somewhere in the water distribution pipe 12 because all the water taps 7 are closed. If the flow meter 21 does not sense the flow rate, it is assumed that there is no water leakage point. In this way, it is determined whether there is a leak point in the water distribution pipe 12 (step S4). If the flow meter 21 does not detect the flow rate, the process proceeds to the next step S7, and if the flow rate is detected, the pump 10 is stopped ( Step S
5) After the water leak point is repaired (Step S6), the process returns to Step S3, and the water leak point is checked again.

In block B1, first, step S
1, even if the water distribution pipe is damaged by an earthquake, it is possible to prevent water leakage from the damaged portion and secondary disasters associated therewith. Further, in the next step S2 to step S6, the water in the building structure 1 Procedures for finding leaks in the distribution pipes and performing emergency repairs are performed.

In the next block B2, the control device 2
The operation of the pump 10 is performed while restricting the water pressure by 3 (step S7). This is a procedure for preserving and using the precious water stored in the receiving tank at the time of disaster as much as possible. At this time, by monitoring the flow rate by the flow meter 21 at the same time, the remaining water is more systematically used. Can be used for

The water supply by the limited pressure shown in step S7 is performed until the city water is restored, and after the city water is restored, the restoration of the water supply facility of the building structure 1 is checked by the procedure shown in block B3. I do. First, with all the water taps 7 closed, the operation of the pump 10 is started at a normal water supply pressure (step S8), and based on whether or not the flow rate is sensed by the flow meter 21 at that time, the location of the leak point in the water distribution pipe 12 is determined. The presence or absence is determined (step S9), and when the flow meter 21 detects the flow rate, the pump 10 is stopped (step S10), and after repairing the leak location (step S11), the flow proceeds to step S8.
Return to and repeat the inspection for water leakage. When the flow rate is not detected by the flow meter 21, it is determined that the water leakage point does not exist, and the normal water supply is started on the assumption that the water supply facility in the building structure 1 has been restored (step 1).
2).

In block 3, before the city water is restored and the normal water supply is started, it can be checked again whether there is any part that leaks due to the water pressure during normal water supply. Thereby, it can be determined whether or not the water supply facility in the building structure 1 has been restored.

Although an example of the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment. For example, it is possible to adopt a gravity type water supply system for water supply equipment. Application to building structures is also effective. FIG.
Is an example in which the present invention is implemented in a building structure employing a gravity type water supply system, and the same devices and structures as those in FIGS. 1 and 5B are the same as those in FIGS. 1 and 5B. Are given. In FIG. 3, a flow meter 25 is interposed between the elevated water tank 11 and the water supply valve 14, and the valve 13, the water supply valve 14, and the flow meter 25 are connected to the control device 23 by an electric circuit 24. .

In this case, the procedure in which the water leakage prevention / water saving system operates is as shown in the flowchart of FIG. The first block B4 is a procedure for preventing water leakage of the water supply equipment in the building structure 1 immediately after the occurrence of the earthquake. First, in step S13, the pump 10 is stopped in response to the vibration of the earthquake detected by the vibration detector 20, The valve 13 and the water supply valve 14 are closed. In the next step S14, after the water tap 7 is closed, a leakage point in the water distribution pipe 12 is inspected in steps S14 to S17 in the same procedure as in steps S3 to S6 described above, and in steps S19 to S22. Inspection of a water leakage point in the water distribution pipe 15 is performed. If no leak is found in both inspections, the next block B5
Proceed to.

In block B5 (step S23), as in block B2, the water receiving tank 2 and the elevated water tank 1
In order to save the remaining water in the water supply system 1, water supply is performed by limiting pressure. In this example, a gravity-type water supply system is used. Control the water pressure inside.

This limited pressure water supply is performed until the city water is restored, and after the city water is restored, the leakage point of the water supply equipment is rechecked in the same manner as in the block B3 described above according to the procedure shown in the block B6. Do. That is, step S
The presence or absence of a leak point in the water distribution pipe 12 is checked according to the procedure as shown in steps S24 to S27, and the procedure as shown in steps S28 to S31 is performed.
A check is made to see if there is a water leakage point in the water distribution pipe 15.
In both procedures (steps S24 to S27 and steps S28 to S31),
If the flow rate is not detected, it is considered that the water supply system in the building structure 1 has been restored (step S3).
2) Start normal water supply.

In the above two embodiments, examples in which the present invention is applied to a relatively high-rise building structure having a water receiving tank are shown. In the case where the present invention is applied to a low-rise building structure on the first or second floor without a water receiving tank, a valve connected to a water supply main pipe may be closed by an output from a swing detector immediately after an earthquake. By doing so, water leakage when the water distribution pipe is damaged by the shaking of the earthquake is prevented. In addition, the water leak point checking function and the water saving function according to the present invention as described above can be used not only at the time of a disaster such as an earthquake but also at normal times for water leak point inspection and water saving.

[0024]

In a building structure provided with a water leakage prevention / water saving system of the present invention, a pump or a water supply valve is closed in conjunction with a swing detector during an earthquake,
The supply of water through these pumps or water supply valves is stopped, and as a result, water leakage and secondary disasters associated therewith can be prevented. In addition, these pumps and water supply valves are equipped with a control device to control the water supply pressure, and at the same time, the flow rate in the distribution pipe is monitored by a flow meter, so that emergency repair of piping equipment in the event of a disaster and water leakage during the restoration of the disaster can be achieved. In addition to being able to recheck the location, it is possible to save and use the water left in the receiving tank and the elevated water tank when the supply of external water is stopped due to the city water disaster.
Further, such a function of the present invention can be effectively utilized not only at the time of disaster but also at normal times.
