Description

[Technical Field]

[0001] The present invention relates to a water supply system for use in disaster areas and areas with heavy snowfall. [Background technology]

[0002] The Noto Peninsula earthquake that occurred on January 1, 2024, left many people affected, but even though recovery efforts are progressing, water supply has not been restored even after four weeks. For example, in Honjo City, relief supplies have arrived, but there is not enough water. A similar water shortage situation is also occurring in Nanao City. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Utility Model Registration No. 3244578 [Patent Document 2] Patent Publication No. 2023-050533 Summary of the Invention [Problem to be solved by the invention]

[0004] During heavy snowfall or disasters, roads are cut off and delivery vehicles cannot reach affected areas, and even if they are able to be accessed, many relief supplies arrive, but water is not available because of burst water pipes and fallen trees, meaning that fresh water for bathing, washing, flushing toilets, etc. cannot be supplied to disaster victims. The problem is that not enough fresh water is reaching the disaster-stricken areas. However, this invention has solved that problem.

[0005] The raw water can be fresh water from distant mountain springs, ponds, lakes, rivers, seas, groundwater, or stored water. There are several methods for water purification, including evaporative cooling, filtering (reverse osmosis membranes, ultrafiltration membranes, etc.), and settling. Although evaporative cooling and filtering are well-known methods for use in disasters, they cannot be sent to remote disaster areas. Furthermore, known fresh water purifiers or tanked fresh water supplies are not designed to transport water over long distances like water pipes, so disaster victims must travel to the fresh water purifier or tank. In this way, when disaster victims or areas are isolated (roads are impassable), they have no access to fresh water at all, and even if they are not isolated, they have to go to great lengths to get water. In other words, there are no simple water pipes in the disaster area. [Means for solving the problem]

[0006] The present invention is characterized in that fresh water is laid from the fresh water supply device onto roads, rivers, and rubble by floating a hose from the ground surface and pulling it to the disaster area. The specific configuration is: This fresh water supply device can be used in disasters such as heavy snowfall or earthquakes, and is characterized by comprising an extendable hose, a device at the tip of the hose for pulling out the hose, a device for changing the direction of the hose, and a device for floating the entire hose, a hose reel at the other end of the hose, a device for winding and extending the hose around the hose reel, a device for drawing water from mountain spring water, ponds, lakes, rivers, seas, groundwater, or stored water and turning the water into fresh water connected to the tip of the hose, and a power source for driving the device for turning the water into fresh water, and the hose can be equipped with a device for lifting the hose from the ground surface, and can be pulled out from the reel while being lifted. [Effects of the Invention]

[0007] It can also provide fresh water even when the area is isolated (roads are impassable). [Brief explanation of the drawings]

[Figure 3] FIG. 4 is a side view showing a second embodiment of the present invention.

[0009] Known water supplies for disasters involve transportation using large tanks or supplying purified water on-site using water purifiers. Transporting large tanks requires the use of large trucks that can withstand the heavy weight of water, making it difficult to pass through damaged areas with rubble, fallen trees, and muddy roads. Even portable types are difficult to move across roads that have been severed and collapsed by earthquakes and to supply water to affected municipalities. The basic mechanism of the fresh water generator used in this invention is known: water pumped up by a pump is passed through a filter, and if necessary, through known filters such as activated carbon filters, ion exchange resins, and membrane filters (ultrafiltration using UF membranes or reverse osmosis using RO membranes), and then sterilized with ultraviolet light, and finally tested for residuals before being supplied for drinking. For example, if the supply capacity is about 2 tons / hour, the device would weigh about 100 kg, and when batteries and other necessary equipment are added, it would not be easy for a person to carry it. However, in cases where roads are cut off, the present invention requires a hose to be extended to supply fresh water further. The present invention solves this problem in one fell swoop by providing a fresh water supply device for use in times of disaster such as heavy snowfall or earthquake. This invention is called Dr. Nakamatsu Mizutsukuru, also known as Dr. Nakamatsu. "Do" means any disaster, "K" means clear, "Ta" means immediate, "Na" means heal, "Ka" means recovery, "Ma" means fresh water, and "Tsu" means produce. This is the name of this invention. It is a water supply device. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0010] [First embodiment of the present invention] 1 and 2 show a first embodiment of the present invention, which is composed of a hose floating device 3, a hose pull-out device 4 at the end of the hose, a hose direction control device 5, a fresh water supply device (with an inspection unit) 6, a power source energy 7 such as a battery for driving the device, a water intake pump 8 from a river or the like 2, an extension hose reel 9, and a hose 10.

[0011] The hose reel, hose reel extension mechanism 9, fresh water supply device 6, power supply battery or generator 7, and water intake pump 8 are mounted as a unit on a vehicle 11 so as to be mobile. This vehicle 11 is set up in a location in the disaster area where there is a means of transportation for moving vehicles. Then, the hose 10 is extended from there to an isolated area where roads are cut off. The devices provided on the vehicle 11 are shown in FIGS. 1 and 2, but the arrangement is not limited to this and any arrangement may be used.

[0012] The hose 10 with the reel extension mechanism 9 is laid in an area where vehicles cannot pass, so it is long enough to reach the disaster area. This hose may be wound around multiple reels 9 and may be divided into sections. As it carries fresh water, a soft, light material and pipe thickness that will not split or leak is preferable. Materials include fluororesin such as tetrafluoroethylene, PP, vinyl, cloth, PE, PFA, and resin. The type to be used depends on the amount of purified fresh water and the length to be transported. Considering the weight and length, hoses with a pipe diameter of 1 / 4 inch to 100 mm diameter are preferable, but there is no need to be limited to this. The reel extension function 9 may be provided with a function to automatically rotate and feed out the hose as the hose is extended. The hose lifting (floating) device installed at the end of the hose and midway along the hose, and the hose pull-out device or hose direction control device installed at the end of the hose utilize the ducted fan and ground effect invented by the present inventor in Patent Application No. 2023-220206 (called a ducted fan (Ukuruma)). Double or single contra-rotating propellers are installed inside the duct to float the hose, and a small propeller duct is installed on the side of the duct, making it movable. Using this floating device 12, the hose 10 is floated and pulled 4, and its direction is controlled 5 so that the hose heads towards the disaster site as its destination.

[0013] The hose lifting device 3 floats and moves over the ground surface, such as rubble, rivers, collapsed roads, fallen trees, collapsed houses, snowy roads, etc. For example, the present inventor invented Patent Application No. 2023-220206, which combines two ducted fan (U-shaped) floating devices 12 and allows the hose to be held in the center 125, making it possible to lift and position the hose to a predetermined position. This ducted fan (U-shaped) is battery-powered or engine-powered, and rotates the propeller 122 to lift it up.

[0014] The hose is lifted and extended from uneven ground by the hose lifting device 3 using multiple ducted fans (wheels) and the hose extension function 4 at the end of the hose. Although the hose is suspended above the ground by the lifting device 3, if there is an obstacle to hose extension, the hose can be safely moved to the left or right without being affected by rubble on the ground by changing the propulsion force of the wheel on the left and right of the hose direction control 5 installed at the end of the hose. The hose pull-out device 4 and the hose direction control device 5 can be a combined device.

[0015] The hose pull-out device 4 at the hose tip 102 is photographed from the air by a drone to determine the direction and height of the hose (not shown), the hose is lifted above the ground, and a reel guides and feeds the hose. This hose pull-out device 4 can be pulled out manually, but it is also possible to use devices 4, 5 in which two of the ducted fans (U-shaped fans) 12 are connected to the hose tip 102 facing horizontally, and another ducted fan 12 is provided below that for lifting. The hose is fed out by the hose pull-out device 4 and the hose floating device 3 at the tip of the hose.

[0016] Then, the extended hose end can be connected to a reel on which a new hose is wound, and the new hose can be extended (not shown). This allows the hose to be connected and extended, and a long-distance water pipe can be secured. Multiple reels can also be used.

[0017] When a human worker is required to connect the reels, the worker can connect the reel and hose by riding in an aircraft such as a helicopter or the U-shaped vehicle invented by the inventor, and the worker can connect the reel and hose securely at the reel's hand. Because the U-shaped vehicle can move by floating slightly above the ground, it is possible to connect and extend hoses in places where vehicles cannot pass, such as in dense forests, near fallen trees, or in rivers.

[0018] According to the first embodiment, water can be supplied even to isolated areas that have been affected by a disaster, and by fixing the hose after it has been extended, the present invention can also be used as a waterworks pipe.

[0019] [Second embodiment of the present invention] A second embodiment of the present invention is shown in Fig. 3. This embodiment is characterized by the ease of transporting water by using the water supply pump, hose, and generator of a known fire engine 112.

[0020] A fresh water device 6 is connected to the front or rear of the pump of the fire engine 112, the hose is extended wherever possible with the fire engine hose, a hose lifting device 3 is provided below the fire engine hose or the hose 10 of the present invention, and the hose lifting device 3, a hose tip hose pull-out device 4, and a hose direction control device 5 are provided at the hose tip 102. The hose reel and reel extension / retraction mechanism 9 of the present invention, hose 10, suction pump 8, water supply pump, and the power source that drives them use the equipment of the fire engine 112. In addition, in order to balance the amount of water transported and the hose pressure, additional water storage tanks and pumps are installed before and after the fresh water device, at the end of the hose, and at the end of the fire engine hose, so that fresh water can be efficiently supplied to each area. If fresh water is not needed, the fresh water device is not needed. Fire engine hoses are made of flat-stitched fabric and come in sizes of 40-70mm in diameter, which can pose hygiene issues and make them difficult to transport due to their heavy weight (e.g., 5-7kg for 20m, exceeding 70kg when filled with water). Furthermore, fire engine pumps have a high discharge pressure (7-1kg / cm²). Therefore, water can be drawn up from a pond, river, etc. using the fire engine hose and stored in a water tank in a safe location. This water can then be used with a low-pressure pump to supply fresh water to disaster areas via hose 10 equipped with the present invention's fresh water supply device, hose floater 3, hose pull-out device 4, and hose direction control device 5.

[0021] According to the second embodiment of the present invention, fresh water or water is pressurized and pumped out by a fire engine, so that large amounts of fresh water can be transported over longer distances.

[0022] [Third embodiment of the present invention] FIG. 4 shows a third embodiment of the present invention, which is characterized in that the hose is installed in a figure-eight winding and can be extended 91 without tangling. When the hose is made of a material that will not collapse, it is preferable to use a figure-eight winding. That is, if the material is a flexible tube hose such as fluororesin such as tetrafluoroethylene, PP, vinyl, PE, PFA, resin, or cable such as electric wire, it can be wound in a figure-eight pattern. The work involves not unwinding the hose with a reel, but placing the hose wound in a figure-eight configuration before use as shown in Figure 4, and then attaching the hose lifting device 3, hose pulling-out device 4, and hose direction control device 5 to the hose in advance, and then extending the tip of the hose so that it is straight. By arranging the hose in a figure-eight shape, the hose can be extended and removed without tangling, saving time and energy as it can be extended with little pulling force.Furthermore, there is an effect that a mechanism for unwinding the reel is not required. Although FIG. 4 shows the hose loop wound in a figure-eight shape being fed out vertically, the hose may be arranged in any manner, and the loops may be stacked horizontally and locked together before being fed out. [Fourth embodiment of the present invention] FIG. 5 shows a fourth embodiment of the present invention, which is characterized in that the hose is installed in a single loop of a figure-eight winding, the loop being arranged vertically, and the hose can be extended 91 without tangling. The fourth embodiment is a modification of the arrangement method of the third embodiment. It is compactly made into one ring, making it easy to transport the hose.

[0023] Although the embodiments have been described above, the present invention also includes configurations that combine these embodiments and configurations that use means for floating and extending the hose at disaster sites. [Industrial Applicability]

[0024] In areas affected by disasters or heavy snowfall, water can be supplied without being obstructed by rubble, etc., and water for drinking, toilet use, laundry, bathing, etc. can be supplied, allowing people to live healthy and normal lives. This invention can therefore develop disaster relief projects and is useful industrially. [Explanation of symbols]
