Description

  The present invention relates to a rainwater management system.

  Most of the installed rainwater storage tanks are for use in small households and business establishments for the purpose of saving water, apart from large-scale items such as public facilities. The mainstream, the purpose of preventing flood damage was not considered. In addition, the installation of water tanks in urban areas had to be made into small water tanks that could be buried in the basement or placed in passages that are not usually used behind the building when installing due to problems of securing space. . Moreover, each of these water tanks is managed independently and used separately, and the range that can contribute to disaster prevention during heavy rain is limited only to the amount of rainfall until each water tank becomes full during initial rain. It was.

  The functions of recreational ponds and adjustment ponds created as measures to prevent water disasters take in river water as the river level rises, so even if you create recreational ponds and adjustment ponds with a large amount of water storage, the risk of flooding really increases. Actually, the range of water storage capacity that can control the amount of water flowing into the river at that time is very small. In case of heavy rain, the risk of flooding and levee breaching became very high, and there was no choice but to wait for the rain to stop by loading sandbags at dangerous places.

  Recent local heavy rains, which are considered to be the effects of global warming and urbanization, have caused flooding of small and medium-sized rivers (6) in urban areas. The main measures for preventing water disasters were construction of a reservoir and regulating pond, widening the width of the river, lowering the riverbed, and raising the height of the bank to increase the amount of water that the river can flow. However, such construction work in urban areas is not easily solved due to problems such as securing land and large construction funds. Water disasters in urban areas are mainly caused by breakage and flooding of small and medium-sized rivers (6) that are in close contact with life flowing in the area, and when a large amount of rain falls, rainwater enters the ground. Since it can not permeate and flows into these small and medium rivers in a short time through drainage channels (7) etc., it easily overflows beyond the control limit of the river and causes great damage. However, the total amount of overflowing rainwater is not so large and is short in time.It is a characteristic of urban flooding. There was a problem such as whether to control.

The rainwater management system of the present invention has been devised to solve the above problems.
The rainwater management system according to claim 1 is a water tank (2) that is installed and used individually for the purpose of effective use of rainwater in each household and business establishment (1), without changing the original purpose of use. Systematize them to work in tandem, divide them into specific areas according to each drainage route of the river, and use a communication line (4) such as a mobile phone that is common from the monitoring center (9) that manages each river The automatic open / close valve (5) that opens and closes with the power of the household power supply or battery installed in the area and connected to the drain pipe of each water tank by sending a dedicated signal allocated for each area It is characterized by being able to prevent disasters caused by rainwater by remotely operating all at once and managing the discharge and storage of the stored water (3) in each water tank (2) quickly and repeatedly.

  The rainwater management system according to claim 2 is the rainwater management system according to claim 1, wherein a water supply / drainage hole (11) is provided at the bottom of each water tank (2) installed on the same flat ground, and each connected from there Connect the pipes and connect the water supply side to the building gutter (12) to store rainwater. From the monitoring center (9) near the drainage groove (7) at the end of the drainage side, connect a communication line (4) such as a mobile phone. An automatic open / close valve (5) that operates by remote command operation is provided, and the water storage (3) of a plurality of connected water storage tanks (2) can be repeatedly controlled for water discharge and storage by operating only one automatic open / close valve. It is characterized by things.

  The rainwater management system according to claim 3 is the rainwater management system according to claim 1 or 2, wherein the water tank (2) is connected in a three-dimensional manner with multiple layers, and the rainwater that has entered the uppermost water tank is The lowermost water tank is sequentially filled with water from the lowermost water tank and the end of the connecting pipe (10) extending from the water supply / drainage hole (11) at the bottom of each water tank so as not to overflow. A water tap (15) with a ball tap is provided in accordance with the upper part of the stored water surface in (2) to control the water supply in each stage of the water tank (2), and the lowermost stored water (3) is used. In the case of reduction, it is constructed in three dimensions because it has the same structure as a large single water tank because it has a structure that supplies water to the lower stage in order from the stored water (3) of the uppermost water tank (2). (2) Retained water (3) of all connected water storage tanks with one automatic opening and closing valve 5) to operate, characterized in that it can be repeated only in the management of drainage and retention.

The present invention has the following effects (a) The rainwater management system of the present invention is a water tank (2) that has been installed and used individually for the purpose of effective use of rainwater in each home and business establishment (1). ) Storage water (3) can be remotely operated for each specific area using the communication line (4), etc., and the automatic opening / closing valve (5) of each door can be remotely controlled. It is possible to store and discharge water into the water storage tank of the area that flows into the river instantaneously according to the rainfall situation and rainfall forecast and the river water level situation by the batch operation of (9), By adjusting the amount of rainwater flowing in, it is possible to prevent disasters caused by rainwater.
(B) The rainwater management system according to the present invention is configured by connecting small water tanks (2) using an empty space even in an area where urban buildings are densely packed. Used for watering gardens, flushing toilets, and washing cars, etc., and in the event of a water disaster, under the control of the management center (9), the automatic open / close valve (5) is remotely operated to prevent disasters caused by rainwater. In addition, the water tank (2) can be connected by using a water tank that can be piped like a bamboo stem, and the number of water tanks (2) can be increased by a single automatic open / close valve (5). It is possible to control the inflow of a large amount of rainwater into rivers in each area by being able to arrange and pipe three-dimensionally in an overcrowded urban space.
(C) Since the rainwater management system of the present invention can instantly operate all the automatic open / close valves (5) in each area by remote control from the management center (9), In the same way, it is different from simply storing the rainwater from the initial stage to reducing the amount of water flowing into the river, and operating the automatic open / close valve (5) after it becomes a risk of flooding. Rainwater can be stored and the amount of rain that flows into the river instantly can be reduced. It is also possible to prepare for the next inundation risk by operating each automatic opening and closing valve (5) when the river flow has a margin and discharging the rainwater stored in the water tank in the area. In this way, there is a strong and weak wave in how to get down even in a heavy rain, and it is possible to control the amount of rain multiple times the water storage tank storage in the area by repeating the water storage and discharge according to this wave, and rainwater disasters Prevention becomes possible.

Hereinafter, embodiments of the present invention will be described.
(A) FIG. 1 is a schematic diagram of the entire system of the present invention.
At present, it is possible to predict the flow of rain clouds and the amount of rainfall from images from meteorological satellites, etc., and it is also possible to see in real time video of dangerous locations in each river. Collecting this information comprehensively, the management center (9) that manages the rivers in each area responds to the risk of each river, and is a wireless and generally used communication line such as a mobile phone (4 ) And sending a unified dedicated number determined for each area, and operating all the automatic opening and closing valves (5) installed in that area at once, seems to be the most dangerous At that time, it is possible to suppress the discharge of rainfall in the entire area to the river and minimize the damage. The automatic opening / closing valve (5) is opened / closed by power from a household power source or a battery, and is operated by a signal instruction from the communication line (4). When the water tank (2) is cleaned and inspected, it can be manually opened and closed independently.
The division of each area is basically based on the drainage route.
(B) FIG. 2 is a view of a small water tank (2) installed in a general home and office (1) in an urban area with little open space.
A small water tank (2) can be connected by connecting pipes (10) like bamboo underground stems using a narrow empty space, and any number of these can be connected and increased on the same flat ground. The stored water (3) in the water storage tank (2) can be discharged or stored by operating one automatic opening / closing valve (5). The automatic opening / closing valve (5) is operated by receiving a signal transmitted from the storage management center (9) by the receiving device (8) of each house.
(C) FIG. 3 is a view of a small water tank (2) installed in three stages using a narrow space in an urban area or the like.
The water tanks (2) are connected in a three-dimensional manner with multiple layers, and the rainwater that enters the uppermost water tank is sequentially stored from the lower water tank to the full, and each stage so that it does not overflow. Automatic water supply control faucet with ball tap (15) with the end of the connecting pipe (10) extending from the water supply / drainage hole (11) at the bottom of the water storage tank aligned with the upper water storage surface of the lower water storage tank (2) In order to control the water supply to the water storage tank (2) of each stage and reduce the water storage using the lowermost storage water (3), the water storage (3) of the uppermost water storage tank (2) is sequentially installed. It has a structure that reduces and supplies water to the lower stage, and has the same function as a single large reservoir, so that (2) stored water (3) of all the three-dimensionally connected and connected reservoirs is placed in one place. Management of water discharge and storage can be repeated simply by operating the automatic opening / closing valve (5).

When operating the rainwater management system of the present invention, it is performed in the following manner.
(B) The administrative side with management rights to the area river designates the area that affects the occurrence of flood damage, divides the area as shown in A to Z of Fig. 1 according to each drainage route, and to the local residents and businesses Considering the subsidy system, etc., we will promote the installation of water storage tanks so that we can store and manage as much rainwater as possible, and build a rainwater management system by remote control using a communication line.
(B) Set the open / close valve of the water tank piping installed in each zone so that it operates with the same signal. In a narrow space in an urban area, as shown in FIG. 2, it is possible to store a large amount of rainwater as much as possible by installing a three-dimensional pipe as shown in FIG.
(C) Normally, the water stored in the water tank can be freely used as the right of the installer as before, but in the event of a disaster, the right to store and discharge water is transferred to the government and It can be stored and discharged as many times as desired by operating the valve until the danger is gone. At that time, it is inevitable that the water stored in the water storage tank will eventually become less than the state before the management right was transferred to the government.
(2) Consider a case where a large amount of rainfall is actually expected and actually rained, or a case where sudden urban concentrated rainfall occurs.
If rainfall is predicted in advance, open all the open / close valves in the area and leave it in the water discharge state to lower the water level in the water tank before the start of raining. When it becomes dangerous, the opening and closing valves of the area divided according to each drainage channel are closed according to the situation by remote control from the management center, and the outflow of rainwater to the river is suppressed. After that, when the rainfall stops and the river water level begins to drop, the opening and closing valves of each area once closed are opened again to release the stored water in each water tank and prepare for the next rainfall. Rain does not always fall in the same tone, and river levels in urban areas change in a short time according to the amount of rainfall. In order to respond to such disasters, it is necessary to freely control the amount of rainfall that flows instantaneously in these rivers. For this purpose, it is possible to do this by sending signals assigned to each area from the control center using the basic communication lines such as mobile phones. The ability to discharge and store the water stored in the water tank as many times as necessary within one low-pressure passing time means that it is possible to control rainwater that is many times larger than the installed water tank capacity.
This system is different from the water damage prevention countermeasure system that cannot fully function when it really wants to show the water storage capacity like a conventional reservoir or regulating pond.

  1 is an overall system diagram of the present invention.   It is the schematic which installed the small water tank in the general household and office of an urban area with few open spaces.   It is the figure which installed the small water tank piled up in three steps using the narrow space in an urban area.
