[0012] [Significance of the technology described in this disclosure] The technology described in this disclosure (hereinafter referred to as "the Technology") is based on a completely new principle of "accelerating water flow by artificial means to rapidly drain water in urban floods (urban inundation) and other similar situations." The Technology is not only a technological breakthrough in disaster prevention equipment, but also has the potential to give rise to entirely new industrial forms based on the concept of "accelerating water flow." In recent years, major cities around the world have been frequently hit by extreme weather and / or inland flooding, so the Technology is expected to become widespread as an emergency drainage system and / or disaster prevention equipment that will be standard equipment for governments in various countries. Furthermore, the Technology will have a huge industrial ripple effect throughout all processes, including manufacturing, maintenance, and transportation, and is expected to create a large number of jobs. Moreover, the Technology has social value in that it can form a new manufacturing industry in Japan and contribute to international disaster prevention by exporting products overseas.

[0013] [Embodiment 1] <Configuration of Water Flow Acceleration System 1> Hereinafter, one embodiment of the present disclosure will be described in detail. Figure 1 shows the appearance of the water flow acceleration system 1 according to this embodiment and a method of using the water flow acceleration system 1. The water flow acceleration system 1 is a system that accelerates and drains water flow in a body of water. Here, "accelerating water flow" may mean increasing the speed along the direction of water flow if there is already water flow in the body of water, or increasing the speed in a direction other than the direction of water flow. It may also mean generating water flow (in other words, increasing the speed of water flow from 0) if there is no water flow in the body of water. The body of water may be a city flooded by heavy rain, or a river or waterway. The body of water may also be a lake connected to a river and / or waterway.

[0014] As shown in FIG. 1, the water flow acceleration system 1 includes three water flow acceleration devices 10. Further, as will be described later, the water flow acceleration device 10 includes one propulsion unit 100. The water flow acceleration system 1 may include any number of water flow acceleration devices 10, the water flow acceleration device 10a described later, the water flow acceleration device 10b described later, the water flow acceleration device 10c described later, or the water flow acceleration device 10d described later, as long as it includes two or more propulsion units 100 as a whole.

[0015] FIG. 2 is a view showing the appearance of the water flow acceleration device 10 according to the present embodiment. As shown in FIG. 2, the water flow acceleration device 10 includes one propulsion unit 100 and an excavator 200.

[0016] (Configuration of Propulsion Unit 100) The propulsion unit 100 is a device used for the propulsion of a ship. The propulsion unit 100 is coupled to the tip of the arm 210 of the excavator 200 described later. The propulsion unit 100 includes a screw 110 and a rotation mechanism 120. The propulsion unit 100 rotates the screw 110 and pushes the water in contact with it in one direction, thereby generating a mechanical thrust as a reaction and propelling the ship in the direction opposite to the direction in which the water is pushed. Therefore, when the propulsion unit 100 is fixed to the water area, it can rotate the screw 110 with a force of the same magnitude as the mechanical thrust and push the water in contact with it in one direction. In other words, when the propulsion unit 100 is fixed to the water area, it can accelerate the water flow in the water area by the mechanical thrust. Hereinafter, the angle (elevation angle or depression angle) at which the rotation axis of the screw 110 intersects the horizontal plane is referred to as the vertical angle of the propulsion unit 100.

[0017] The rotation mechanism 120 is a member that rotatably connects the part where the propulsion unit 100 is coupled to other members (hereinafter referred to as the "coupling part") and the main body of the propulsion unit 100 including the screw 110 (hereinafter referred to as the "propulsion unit main body"). The rotation mechanism 120 may be integrated with either the coupling part or the propulsion unit main body. The propulsion unit 100 can adjust the direction of the rotation axis of the screw 110 (hereinafter referred to as the "horizontal angle of the propulsion unit 100") by the rotation mechanism 120. According to this configuration, the water flow acceleration system 1 can not only accelerate the water flow in one direction but also accelerate the water flow in another direction. For example, the water flow acceleration system 1 can accelerate the water flow downstream of the river or accelerate the water flow upstream of the river (i.e., generate a countercurrent against the water flow). In other words, the water flow acceleration system 1 can control the water flow in both directions.

[0018] The propulsion unit 100 may be modularly designed. As an example, the propulsion unit 100 may further include a power device and may be designed to be able to realize the above functions independently. According to this configuration, each of the propulsion units 100 can operate independently. In addition, since the propulsion unit 100 can be quickly replaced, added, or removed and can be easily transported, the water flow acceleration system 1 can respond emergently to drainage in a disaster site where heavy rain has occurred and / or in an area remote from the location where the propulsion unit 100 is stored.

[0019] Furthermore, the propulsion unit 100 may be adapted to power supply by power from at least any one of a power line, a generator, and a storage battery. In other words, the propulsion unit 100 may be adapted to power supply by power from an external power device. Here, the generator and the storage battery may be power devices provided in the main body 240 of the excavator 200 described later. According to this configuration, the water flow acceleration system 1 can operate stably even when power is cut off due to heavy rain or in a remote area where it is difficult to secure power.

[0020] Furthermore, if the propulsion unit 100 is compatible with power supply from a generator, the generator may be at least one of a gasoline engine or a diesel engine that also functions as a generator. With this configuration, stable operation is possible using portable petroleum fuel even when there is a power outage due to heavy rain, in remote areas where it is difficult to secure a power source, or in cold regions where low temperatures make it easy for batteries to discharge.

[0021] (Configuration of excavator 200) The excavator 200 is a heavy machine primarily used for excavating the ground. The excavator 200 comprises an arm 210, a mobile device 220, a slewing mechanism 230, and a main body 240.

[0022] The arm 210 is a device extending from the main body 240. The arm 210 supports a component (hereinafter referred to as the "end component") that is connected to the tip of the arm 210. Here, the end component may be a propulsion unit 100, or an attachment for a conventional excavator (such as a bucket), and a propulsion unit 100 fixed to the attachment. Furthermore, the propulsion unit 100 may be detachably connected to the tip of the arm 210, or detachably fixed to the attachment. In this embodiment, the "shaft of the end component" refers to the rotation axis of the screw 110 of the propulsion unit 100 of the end component.

[0023] The mobile device 220 is connected to the underside of the main body 240 via a swivel mechanism 230. The mobile device 220 transports the main body 240.

[0024] The swivel mechanism 230 is a device that rotatably connects the main body 240 to the moving device 220.

[0025] The main body 240 is a component for controlling the operation of the propulsion unit 100 and other devices provided by the excavator 200. The main body 240 can start or stop the propulsion unit 100. The main body 240 can also move the arm 210 to adjust the position in space, including the height of the tip component, and the angle at which the axis of the tip component intersects the horizontal plane (i.e., the vertical angle of the propulsion unit 100). The main body 240 can also operate the moving device 220 to move the water flow accelerator 10 itself. Furthermore, the main body 240 can operate the slewing mechanism 230 to change the orientation of the main body 240 itself relative to the moving device 220, thereby changing the direction of the axis of the tip component (i.e., the horizontal angle of the propulsion unit 100). Furthermore, even if the propulsion unit 100 does not have a rotation mechanism 120 and the excavator 200 does not have a slewing mechanism 230, the main body 240 can operate the moving device 220 to change the orientation of the water flow accelerator 10 itself and change the direction of the axis of the tip component (i.e., the horizontal angle of the propulsion unit 100).

[0026] The main unit 240 may have a space for accommodating workers, and may perform the above control according to input from workers accommodating in that space. Alternatively, the main unit 240 may perform the above control according to instructions indicated by signals received from the remote control device 30, which will be described later.

[0027] Furthermore, the main body 240 may be equipped with a power unit for supplying power to the propulsion unit 100 and other devices provided by the excavator 200. The power unit may be at least one of a gasoline engine, a diesel engine, and a battery. Here, if the power unit is at least one of a gasoline engine and a diesel engine, the power unit may supply power as electricity. In other words, at least one of a gasoline engine and a diesel engine may also function as a generator.

[0028] The excavator 200 may be a commercially available excavator (a so-called "backhoe") used at construction sites, etc. Alternatively, the excavator 200 may be a heavy machine primarily used for purposes other than excavating the ground (such as a crane or pile driver), as long as it is equipped with at least an arm 210, a moving device 220, and a main body 240, or it may be a heavy machine developed and manufactured for the water flow acceleration system 1.

[0029] Furthermore, the excavator 200 is preferably a tracked vehicle. In other words, the mobile device 220 is equipped with tracks. Tracked vehicles are suitable for traveling on uneven terrain. Therefore, the water flow accelerator 10 can enter even if the area around a river, waterway, or lake is complex. Thus, the water flow accelerator system 1 can expand its deployable area. Also, tracked vehicles have a larger contact area with the ground compared to wheeled vehicles. Therefore, the water flow accelerator 10 can maintain its posture even when the water flow in the water body drained by the water flow accelerator system 1 is large. In addition, tracked vehicles can perform pivot turns by moving their left and right tracks in opposite directions. Therefore, the main body 240 can change the orientation of the water flow accelerator 10 itself without moving, even if the excavator 200 is not equipped with a turning mechanism 230.

[0030] <Modified form of the water flow accelerator 10> Figure 3 shows the external appearance of a modified water flow accelerator 10a, which is a modified version of the water flow accelerator 10. As shown in Figure 3, the water flow accelerator 10a is equipped with a propulsion unit 100a and an excavator 200. Also as shown in Figure 3, the propulsion unit 100a is equipped with a screw 110a and a rotating mechanism 120. Although the propulsion unit 100a has a different shape from the propulsion unit 100, it has the same function as the propulsion unit 100.

[0031] Figure 4 shows the external appearance of a water flow accelerator 10b, which is another modification of the water flow accelerator 10. As shown in Figure 4, the water flow accelerator 10b comprises two propulsion units 100 and an excavator 200. The number of propulsion units 100 in the water flow accelerator 10b may be three or more.

[0032] <How to use the water flow acceleration system 1> Returning to Figure 1, we will now explain how to use the water flow acceleration system 1. As an example, we will explain how to use the water flow acceleration system 1 for river drainage. As shown in Figure 1, the water flow acceleration system 1 is deployed along the riverbank. Specifically, the three water flow acceleration devices 10 of the water flow acceleration system 1 are arranged along the riverbank, and the propulsion unit bodies of each propulsion unit 100 are submerged in the river.

[0033] Each water flow accelerator 10 adjusts the horizontal angle and vertical angle of the propulsion unit 100 to predetermined values. In this embodiment, the predetermined value of the horizontal angle of the propulsion unit 100 is the same as the direction of the water flow. The predetermined value of the vertical angle of the propulsion unit 100 is the same as the slope of the water surface.

[0034] Furthermore, each water flow accelerator 10 moves its arm 210 to adjust the depth of the propulsion unit body of the propulsion unit 100 from the water surface to a predetermined value, and also adjusts the position of the propulsion unit body of the propulsion unit 100 so that the rotation axis of the screw 110 is on the same straight line.

[0035] (Effects of Water Flow Acceleration System 1) By adjusting the horizontal angle, vertical angle, and position of the propulsion unit 100, including the depth of the propulsion unit body from the water surface, the water flow acceleration system 1 can align the rotation axes of each screw 110 on a straight line that is in the same direction as the water flow and parallel to the water surface. This allows the water flow accelerated by one propulsion unit 100 to be further accelerated by another propulsion unit 100. In other words, the water flow acceleration system 1 can improve drainage efficiency by aligning the rotation axes of each screw 110 on a straight line and accelerating the water flow in a relay manner.

[0036] Furthermore, the time required to manufacture the water flow acceleration system 1 is shorter than the time required to construct drainage devices or systems such as spillways and / or pumps for preventing or controlling urban or river flooding. Also, the cost of manufacturing the water flow acceleration system 1 is lower than the cost of constructing the aforementioned drainage devices or systems. Moreover, the water flow acceleration system 1 can be deployed and used for drainage in an emergency.

[0037] The adjustment of the propulsion unit 100 described above can be performed by the configuration of the water flow acceleration system 1, regardless of the deployment location. Therefore, this adjustment is possible even if the deployment location of the water flow acceleration system 1 is not flat. Thus, the water flow acceleration system 1 can efficiently drain rivers even when deployed on riverbanks, which are often uneven and undulating, as shown in Figure 1. For this reason, the water flow acceleration system 1 is suitable for river drainage applications.

[0038] The above describes, as an example, how to use the water flow acceleration system 1 for river drainage. The water flow acceleration system 1 may also be used for draining urban areas flooded by heavy rain. In this case, the water flow acceleration system 1 is deployed around the area. The water flow acceleration system 1 can be deployed by selecting flat areas within the city and distributing the water flow acceleration devices 10 to those locations. Furthermore, even if the water flow acceleration system 1 is deployed in an uneven area, it can still efficiently drain the area as described above. Therefore, the water flow acceleration system 1 is also suitable for urban drainage applications.

[0039] As described above, the water flow acceleration system 1 is a water flow acceleration system suitable for drainage applications in cities or rivers, and is characterized by comprising two or more propulsion units 100, each of which accelerates the water flow by mechanical thrust. With this configuration, the water flow acceleration system 1 can improve the drainage efficiency of water bodies such as flooded cities, rivers, and waterways in a short period of time and at low cost, and reduce the risk of flooding.

[0040] Furthermore, as described above, the water flow acceleration system 1 is characterized in that each propulsion unit 100 is coupled to an excavator 200. With this configuration, the drainage efficiency can be further improved by aligning the position and / or angle, including the height, of each propulsion unit 100, depending on the configuration of the excavator 200.

[0041] Furthermore, one or more of the propulsion units 100 may be operated in conjunction with urban or river drainage infrastructure. The drainage infrastructure may be at least one of a pumping station, a weir, and a sluice gate. The water flow acceleration system 1 may select the water area to be drained and determine the direction in which to accelerate the water flow based on information including the drainage capacity of the drainage infrastructure and the current amount of drainage. The water flow acceleration system 1 may receive signals indicating this information via wired and / or wireless means. With this configuration, the water flow acceleration system 1 can cooperate with the drainage infrastructure and further improve drainage efficiency.

[0042] Furthermore, the water flow acceleration system 1 may increase or decrease the number of propulsion units 100 depending on parameters relating to the city or river. These parameters may be, for example, at least one of the following: the area of ​​the flooded city or district within the city, the length of the river, and the strength of the water flow (e.g., the speed of the water flow). The water flow acceleration system 1 may increase the number of propulsion units 100 if the area of ​​the flooded city or district within the city is large, the river is long, or the water flow is strong. Conversely, the water flow acceleration system 1 may decrease the number of propulsion units 100 if the area of ​​the flooded city or district within the city is small, the river is short, or the water flow is weak. With this configuration, the water flow acceleration system 1 can flexibly increase or decrease the number of propulsion units 100. In addition, when a user of the water flow acceleration system 1 (hereinafter simply referred to as "user") uses the water flow acceleration system 1 in multiple water bodies, they can appropriately distribute the propulsion units 100 to each water flow acceleration system 1. Therefore, when a user drains water over a wide area spanning multiple bodies of water, they can adjust the drainage of each body (drainage adjustment) and manage floods over the wide area, such as preventing or controlling them (flood management).

[0043] The number of propulsion units 100 may be increased or decreased by adding or removing propulsion units 100 if the propulsion units 100 are modularly designed. Alternatively, the number of propulsion units 100 may be increased or decreased by adding or removing water flow accelerators 10 if the water flow accelerators 10 are modularly designed (for example, if the water flow accelerators 10 are equipped with a power unit).

[0044] The above describes how to use the water flow acceleration system 1 to prevent or control floods. The water flow acceleration system 1 may also be used as a drainage tool to meet temporary drainage needs. Temporary drainage includes blocking and draining flooded roads, draining rivers under bridges for bridge construction, and draining groundwater generated during tunnel construction. With this configuration, the water flow acceleration system 1 can respond to emergencies in addition to drainage regulation and flood management.

[0045] Furthermore, the above has described a water flow acceleration system 1 comprising two or more propulsion units 100 in total, and a method of using the water flow acceleration system 1. However, when draining a small body of water (for example, a small river or waterway), drainage is possible without accelerating the water flow in a relay manner. Therefore, a water flow acceleration system comprising one or more propulsion units 100 or propulsion units 100a in total (for example, a water flow acceleration system comprising one water flow accelerating device 10, a water flow accelerating device 10a, or a water flow accelerating device 10b) can be used as a tool for draining a small body of water. In other words, a water flow accelerating device 10, a water flow accelerating device 10a, or a water flow accelerating device 10b can be used individually as a tool for draining a small body of water. Therefore, according to the above configuration, the water flow accelerator 10, water flow accelerator 10a, or water flow accelerator 10b can improve the drainage efficiency of small bodies of water and reduce the risk of flooding in a short period of time and at low cost. Furthermore, because the water flow accelerator 10, water flow accelerator 10a, or water flow accelerator 10b requires little area for placement, they can be used even in bodies of water where there is limited space for placement.

[0046] [Embodiment 2] Other embodiments of this disclosure are described below. For the sake of convenience, components having the same function as those described in the above embodiments are denoted by the same reference numerals, and their descriptions are not repeated.

[0047] Figure 5 shows the external appearance of the water flow acceleration system 2 according to this embodiment. As shown in Figure 5, the water flow acceleration system 2 includes three water flow acceleration devices 10, which are the same configuration as those of the water flow acceleration system 1, as well as an environmental monitoring device 20 and a remote control device 30. The water flow acceleration system 2 may have any number of water flow acceleration devices 10, water flow acceleration devices 10a, or water flow acceleration devices 10b, as long as it comprises two or more propulsion units 100 as a whole.

[0048] The environmental monitoring device 20 is installed in or near the water body to be discharged, collects environmental information, and transmits a signal indicating the environmental information to the remote control device 30. The environmental monitoring device 20 may be at least one of a water level sensor, a rain gauge, and a flow meter.

[0049] The remote control device 30 is installed at a location away from the water body to be drained and controls the operation of the water flow accelerator 10. Specifically, the remote control device 30 automatically or manually transmits signals indicating operation instructions to each of the water flow accelerators 10 via wired and / or wireless means.

[0050] The operation instruction may be an instruction to start the operation of the propulsion unit 100, or an instruction to stop the operation of the propulsion unit 100. Alternatively, the operation instruction may be an instruction to adjust at least one of the following: the position of the propulsion unit body, the vertical angle of the propulsion unit 100, or the horizontal angle of the propulsion unit 100. Furthermore, the operation instruction may be an instruction to move the water flow accelerator 10 itself.

[0051] Furthermore, the operation instructions may be determined automatically or by the user based on environmental information indicated by signals received from the environmental monitoring device 20. For example, if the environmental information indicates at least one of the following: water level in a body of water exceeding a threshold, rainfall exceeding a threshold, or flow velocity in a body of water below a threshold, the operation instruction may be determined to start the operation of the propulsion unit 100. Alternatively, if the environmental information indicates at least one of the following: water level below a threshold, rainfall below a threshold, or flow velocity in a body of water exceeding a threshold, the operation instruction may be determined to terminate the operation of the propulsion unit 100.

[0052] The main body 240 of the excavator 200 of each water flow accelerator 10 controls the operation of the propulsion unit 100 and other devices of the excavator 200 based on instructions indicated by signals received from the remote control device 30, as described in Embodiment 1. For example, if the instruction is to start the operation of the propulsion unit 100, the main body 240 starts the propulsion unit 100. If the instruction is to stop the operation of the propulsion unit 100, the main body 240 stops the propulsion unit 100.

[0053] As described above, the water flow acceleration system 2 is characterized by comprising the configuration of the water flow acceleration system 1, an environmental monitoring device 20, and a remote control device 30. With this configuration, the user can control the starting and stopping of each propulsion unit 100 automatically or manually by remote control from a safe location, and the water flow acceleration system 2 realizes real-time drainage adjustment and flood management, as well as improved safety.

[0054] [Variation] Other embodiments of this disclosure are described below. For the sake of convenience, components having the same function as those described in the above embodiments are denoted by the same reference numerals, and their descriptions are not repeated.

[0055] In the water flow acceleration devices 10, 10a, and 10b according to the above embodiments, the propulsion unit 100 or propulsion unit 100a is fixed to an excavator 200 that can adjust at least one of the height of the propulsion unit body and the vertical angle of the propulsion unit according to the water level of the water body. Alternatively, the propulsion unit 100 or propulsion unit 100a may be installed on a columnar structure 40 (structure) or a floating structure 50 (structure) described later, which is fixed to the flowing water. In this case, the water flow acceleration device may have an adjustment mechanism for adjusting at least one of the height of the propulsion unit body and the vertical angle of the propulsion unit according to the water level of the water body. The water flow acceleration system 3 according to this modified example will be described below.

[0056] The water flow acceleration system 3 according to this modified example comprises at least one of the water flow acceleration device 10c and the water flow acceleration device 10d.

[0057] Figure 6 shows the external appearance of the water flow accelerator 10c. The water flow accelerator 10c comprises a propulsion unit 100 and an adjustment mechanism 301. The propulsion unit 100 is fixed to the columnar structure 40.

[0058] The columnar structure 40 is a columnar structure fixed to the bottom of a body of water. Examples of columnar structures 40 include bridge structures such as the piers of bridges spanning rivers, pillars that support riverbanks, and utility poles along urban roads.

[0059] The adjustment mechanism 301 consists of a height adjustment device 311 and a vertical angle adjustment device 321. The height adjustment device 311 is a device for adjusting the height of the propulsion unit body of the propulsion unit 100. For example, the height adjustment device 311 is a rail fixed to the side of the columnar structure 40 to which the propulsion unit 100 is connected. The vertical angle adjustment device 321 is a device for adjusting the vertical angle of the propulsion unit 100. For example, the vertical angle adjustment device 321 is a hinge provided at the joint of the propulsion unit 100.

[0060] Figure 7 shows the external appearance of the water flow accelerator 10d. The water flow accelerator 10d comprises one or more propulsion units 100 and an adjustment mechanism 302. The propulsion units 100 are fixed to the floating structure 50.

[0061] The floating structure 50 is a floating structure that remains suspended in the same location in the water. One example of the floating structure 50 is a floating platform such as a barge. The floating structure 50 may be fixed to the columnar structure 40 in order to remain suspended in the same location in the water.

[0062] The adjustment mechanism 302 consists of a height adjustment device 312 and a vertical angle adjustment device 322. The height adjustment device 312 is a device for adjusting the height of the propulsion unit body of the propulsion unit 100. For example, the height adjustment device 312 is a hinge provided on the part of the floating structure 50 that connects to the columnar structure 40. The vertical angle adjustment device 322 is a device for adjusting the vertical angle of each propulsion unit 100. For example, the vertical angle adjustment device 322 is a hinge provided on the connecting part of the propulsion unit 100.

[0063] As described above, the water flow acceleration system 3 is characterized in that each propulsion unit 100 is installed on a structure fixed to the flowing water and has an adjustment mechanism that adjusts at least one of its height and vertical angle according to the water level. With this configuration, the stability of the water flow acceleration system 3 is ensured, and the drainage efficiency can be further improved by aligning the height and / or angle of each propulsion unit 100.

[0064] Furthermore, as described above, the water flow acceleration system 3 is characterized in that the structure is a bridge structure, a floating platform, or a quay wall support. With this configuration, the water flow acceleration system 3 can flexibly adapt to different terrains (mountainous areas, river mouths, etc.).
