Description

The present invention relates to an on-demand simple water supply system.

In recent years, along with the declining population and the aging of water pipes, there has been a problem of rising water costs not only in depopulated areas but also in provincial cities. In addition, the water supply system that is normally used is almost non-functional during disasters such as earthquakes and floods, so there is a problem that water for domestic use tends to be short in disaster areas. In addition, the current water supply environment in Japan is limited to two systems, namely, water supply and simple water supply.

For example, in Japanese Patent No. 3177815 (Patent Document 1), it is possible to take in river surface water in a limited site, it is compact, has good pumping efficiency, and is safe, workable, economical, etc. A superior river surface water intake system is described. However, Patent Document 1 does not relate to utilization of water after pumping.

In addition, Japanese Patent Application Laid-Open No. 2018-190301 (Patent Document 2) describes a tap water delivery system and a tap water delivery method, and can communicate with water trucks as an alternative to piped water supply to water facilities. The operation management server connected to receives at least one data of the water level meter, the water flow meter, and the water residual chlorine meter installed in the distribution reservoir or the water receiving tank, and from the received data, the residual of the water distribution reservoir or the water receiving tank It predicts the amount of water and notifies the water tanker of the scheduled water supply amount and water supply time according to the prediction. According to this, it is described that a specified amount of tap water loaded from a water purification plant or the like is delivered to a specified location at a specified time with appropriate residual chlorine.

The technology described in Patent Literature 2 requires the use of water trucks and is not suitable for long-term operation in depopulated areas or disaster areas.

Hereinafter, the present invention will be described using embodiments, but the present invention is not limited to the embodiments described later. FIG. 1 shows an exemplary simple water supply system of this embodiment. The simple water supply system has a conduit 160 for supplying water, for example, the conduit 160 can use a highly recyclable and replaceable one, and is formed of a plastic material such as vinyl chloride, and along the utility pole 104, Each is fixed to the utility pole 104 at the same position as the electric wire on the top of the utility pole. When installing a new utility pole 104, it is desirable to replace one of several utility poles with a dedicated multi-purpose pole (Utility Pole). In addition, it is preferable that the pole-mounted transformer for electric power and the simple water supply system for ordinary times are not installed on the same utility pole to reduce the weight burden. In Japan, where the electrification rate is almost 100%, utility pole water supply can significantly reduce costs compared to digging up the ground and laying water pipes.

A branch valve and a drain valve 106 are installed on each utility pole 104 to receive domestic water sent from a conduit 160 and supply the domestic water to each user's home 100 . In the present embodiment, domestic water includes drinking water and refers to water that can be used for face washing, bathing, washing, toileting, and the like. In most parts of Japan, it is easy to obtain raw water, and our Japan is a rare and grateful country in the world. Domestic water can be supplied from, for example, a well 140, a water storage tank in an apartment, a water storage tank 109 in an emergency stockpile warehouse, a lake 110, a river 120, a water supply boat 130, and other water sources. If it is empty, it can be fed through a simple clarifier as appropriate.

When a user sends a request for domestic water from a mobile terminal 170 such as a smart phone to a management center that manages a simple water supply system, domestic water is pumped up from the nearest water source and sent to the user's home through a conduit 160. , the branch valve closest to the user's home is opened, and water is accumulated in the water tank 103 arranged at the user's home. Accumulated domestic water is pumped out by a pressurizing pump 107 that pressurizes and adjusts the supply water pipeline provided in the water tank 103, and is supplied to the user from the faucet 101 at the water pressure.

In addition, a drain valve 106 arranged corresponding to the branch valve or separately from the branch valve is installed to drain domestic water remaining without being supplied to the user from the inside of the conduit 160 and through the utility pole 104. Used to channel excess domestic water to the ground. A system that allows for a small amount of controlled waste water to keep costs down. Since most of them are not buried pipelines, underground hollowing due to water leakage is unlikely to occur. Normally, almost no water remains in the pipeline, but if domestic water remains, compressed air may be used to drain the remaining water. For example, the conduit 160 is formed of a rigid PVC pipe, and can be arranged so as to be inclined in one direction with a shift of about half the diameter of the adjacent conduit 160 connecting between the utility poles 104 . If the drainage function of the pipeline is thorough, the freezing of the water pipe can be avoided.

According to this arrangement, after domestic water is supplied, the domestic water remaining in the conduit 160 flows to the utility pole 104 side, and flows down the utility pole 104 from the drain valve 106 installed on the utility pole 104 to the ground. Therefore, in the present embodiment, unused water is prevented from remaining in the conduit 160 for a long period of time, and domestic water can be supplied on demand at all times.

A list of nearby users is assigned to the branch valve, and when a user sends a request for domestic water from an information terminal 170 such as a smart phone, tablet PC, flip phone, or desktop PC, the nearest water source is displayed. By operating the water pump arranged in the water supply, water is supplied to the conduit 160 for supplying domestic water to the user. In this case, domestic water is also sent to users registered in the same branch valve, but surplus domestic water is accumulated in the water tank 103 and is not wasted. In addition, during normal use, demand is generated every day, so the quality of the water in the water tank is sufficiently high to serve as drinking water.

Also, in the event of a disaster, for example, the water supply boat 130 is used as a water source, and a charging stand for EV, EV, FCV, or power supply vehicle is used as a power supply to operate the pump, branch valve, etc. of the simple water supply system of this embodiment. It can also function as an emergency water source. In addition, a drone helipad 105 can be installed on the utility pole 104 to enable direct supply of domestic water by a large drone. Drones can also fly several tens of drones in formation and fly from a base to a disaster area, for example, by group control.

FIG. 2 is a schematic diagram of a local city where the simple water supply system of this embodiment is installed. Local cities have a roadside station 200, a clinic 201, a city hall 202, a post office 203, a supermarket 204, an electric car store 205, and a utility pole 206 with mobile outlets. provided. In addition, each facility is equipped with a charging station for EVs that functions as a power supply for the simple water supply system of this embodiment. can be used as

The simple water supply system of this embodiment does not require a large investment in equipment other than the utility pole 104 and the conduit made of lightweight plastic material, and the existing system for charging the EV can be diverted as a power supply for operation. Therefore, it can be constructed at low cost and can be used as an agricultural water supply for plant factories that use purified water. In addition, this purified water can be supplied as raw water to facilities that produce hydrogen in areas with few populations. Manufacturing costs can be reduced by using a simple water supply system that normally requires less facility costs. In addition, in the event of a disaster, it is possible to store the necessary materials in a stockpile warehouse, etc., and effectively use the water sources and power sources such as EVs that can be used in the immediate vicinity of the disaster area to build a simple water supply system. It also functions as an emergency water source system.

In addition, in this embodiment, the conduit 160 can be extended along the ground without extending along the top of the utility pole 104, and the faucet 101 is directly attached to the tip of the conduit 160 instead of the water tank 103, Domestic water can be provided.

It should be noted that during a drought, there is no water at the water source, so the water supply facilities during normal times cannot be used much. If you install a simple water supply system for disasters, you can deliver the minimum amount of water for domestic use. It is also possible to send relief water from a region with abundant water to a drought-prone region.

In addition, AI will be used to derive multiple optimal water channels, calculate the location and supply capacity of water supply points, and prepare software that determines the optimal water supply route and newly required parts. Then, by organically connecting simple water supply systems in normal times at various places, domestic water is supplied to an intermediate water storage tank in a drought area for a fee. In the study of the water channel, it is possible to reduce the electric power used to drive the pump by adopting a design that utilizes the siphon structure and the capillary principle.

If water is constantly supplied by multiple water supply routes, the amount of water per hour is small, but it can cover the domestic water supply of a small city. Instead of using a thick water main, it is possible to use the intelligence of the normal simple water supply system to send water by using a capillary water pipe on the surface.

FIG. 3 illustrates an embodiment of a utility pole 104 that can be used with exemplary embodiments. A utility pole 104 shown in FIG. 3 has a conduit 160 installed at its top, and a helipad 105 for a drone is installed at the top thereof so that a large drone 302 can land in the event of a disaster. . In addition, a small wind power generator 300 and a solar panel 301 are installed on the platform forming the helipad 105, and a secondary battery 303 installed at an appropriate position on the utility pole 104 is charged with electric power for emergencies. are doing. The helipad 105 can be formed to be rotatable around the utility pole 104, and the rotation can be controlled so as to optimize the power generation efficiency of the wind power generation equipment 300 and the solar cell panel 301.

Note that the utility pole 104 shown in FIG. 3 converts the electric power of the EV charging outlet and the secondary battery 303 into commercial power, and is capable of operating electric appliances driven by commercial power. good. Unlike the continuation of the water supply business through privatization and regional expansion, which are mainly institutional reforms, this application is a proposal to continue the water supply business at a low cost using new technology. Private companies such as water majors will enter the concession system only in large cities where they can expect profits, and rural areas will not be saved.
