[0006] [Figure 1] FIG. 1 is a diagram showing a configuration of an apparatus according to an embodiment. [Figure 2] 10A and 10B are diagrams showing the state of a balloon and a waterstop according to an embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0007] The following describes embodiments of the present invention with reference to the drawings. However, the present invention is not limited to the following embodiments unless it is contrary to the spirit of the present invention. Furthermore, the description of the effects is only one aspect of the effects of the embodiments of the present invention, and is not limited to those described here. In the drawings described below, the same or corresponding components are assigned the same reference numerals, and redundant description will be omitted.

[0008] <Device> FIG. 1 is a diagram showing the configuration of an apparatus according to an embodiment, showing the entire apparatus as viewed from the front. The apparatus 10 includes one or more balloons 1, a pump 2, and a waterstop 3. The apparatus 10 may also include a float switch 4, a lamp 5, and piping 6. The float switch 4 is installed in a rainwater catch basin 7. In FIG. 1, the waterstop is vertical to a horizontal plane.

[0009] The balloon 1 is not particularly limited as long as it expands when fluid is introduced and contracts when the fluid is removed. When the balloon 1 expands, it pushes up the waterstop 3 installed above the balloon 1. The number of balloons 1 may be one or more. The shape of the balloon 1 is not particularly limited, but examples include those that become spherical, ellipsoid, or rectangular parallelepiped when inflated. The material of the balloon 1 is not particularly limited, and various materials such as rubber, vapor-deposited film, and polyethylene film are examples. However, a material strong enough to prevent the balloon 1 from bursting due to the weight of the waterstop 3 when the device 10 is activated is preferred. The size of the balloon 1 is not particularly limited, but it must be large enough to ensure that the waterstop 3 is perpendicular to the horizontal plane when the device 10 is activated. Therefore, it is preferable to use a balloon 1 that can expand to a radius of at least 80 to 120 mm, for example, a balloon 1 that can expand to a radius of at least 100 mm. When the device 10 is not activated, the balloon 1 is deflated, so it does not take up any extra space. The method for removing the fluid from the balloon 1 is not particularly limited, and examples thereof include a method in which the pipe 6 connected to the pump 2 is branched and a valve is connected to the tip of the branched pipe 6 to release the fluid when the device 10 is stopped, a method in which a solenoid valve that automatically opens when the power is cut is provided in the balloon 1 to release the fluid outside the balloon 1 when the device 10 is stopped, and a method in which the pump 2 is operated in the reverse direction to suck the fluid back out of the balloon 1. The type of valve is not particularly limited, and examples thereof include various valves such as a ball valve for resin pipes, a gate valve, and a globe valve.

[0010] The fluid sent to the balloon 1 is not particularly limited as long as it is a gas or a liquid. The gas is not particularly limited, and examples thereof include oxygen, nitrogen, carbon dioxide, and air, which is a mixture of various gases. The liquid is not particularly limited, and examples thereof include water.

[0011] The pump 2 is not particularly limited as long as it can send fluid to the balloon 1, but it is preferable to use an electric pump or a blower pump in order to automate the device 10. The pump 2 sends a predetermined amount of fluid to the balloon 1. The predetermined amount is not particularly limited, but it is preferable that the amount is such that the balloon 1 is sufficiently inflated so that the waterstop 3 is perpendicular to the horizontal plane, and that the balloon 1 does not burst due to the fluid sent to the pump 2. The pump 2 is connected to the balloon 1 by piping 6. When multiple balloons 1 are installed, the pump 2 may be configured to be connected to each balloon 1 by piping 6, or the balloons 1 may be connected to each other by piping 6 so that a single pump 2 can send fluid to all of the balloons 1.

[0012] The waterstop 3 is not particularly limited as long as it can prevent water from the road surface from flowing into areas lower than the road surface when the waterstop 3 transitions to a vertical position relative to the horizontal plane during operation of the device 10. The material of the waterstop 3 is not particularly limited, and various materials such as acrylic, stainless steel, and aluminum can be used. However, since it is necessary to prevent water from the road surface from flowing into areas lower than the road surface during operation of the device 10, a material strong enough to withstand the pressure of water from the road surface is preferable. The waterstop 3 may be a single plate or a plate-like structure formed by connecting multiple plates, depending on the size of the area to be watertight. Figure 2(a) shows the state of the balloon 1 and the waterstop 3 when the device 10 is not operated. The waterstop 3 is installed above the balloon 1. When the device 10 is not operated, it is horizontal and can be considered the same as the road surface, allowing vehicles and other vehicles to pass over the waterstop 3. 2(b) is a diagram showing the state of the balloon 1 and the waterstop 3 when the device 10 is activated. The waterstop 3 is equipped with a hinge (not shown), and when the device 10 is activated, as the balloon 1 expands, it transitions from a horizontal state to a state perpendicular to the horizontal plane, being pushed up by the expanding balloon 1. For example, if a parking lot or the like is located down a slope from the road surface, the waterstop along the boundary between the road surface and the slope will be perpendicular to the horizontal plane, blocking water on the road surface side and preventing water from entering the parking lot or the like.

[0013] The piping 6 is not particularly limited as long as it connects the pump 2 and the balloon 1 and / or connects the balloons 1 to each other. The material of the piping 6 is not particularly limited, and examples thereof include various materials such as silicone rubber, nylon, and metal.

[0014] The float switch 4 is not particularly limited as long as it detects the water level in the rainwater manhole 7. The float switch 4 is installed inside the rainwater manhole 7. The float switch 4 detects the water level in the rainwater manhole 7, and turns on when the water level in the rainwater manhole 7 reaches a predetermined first water level, and turns off when the water level falls below a predetermined second water level. When the switch is turned on, the pump 2 is activated and fluid is pumped into the balloon 1. The predetermined first water level is not particularly limited, but is preferably 20 to 40 cm, for example, 30 cm, from the viewpoint of reliably detecting a rise in the water level. The balloon 1 may be configured to drain the fluid when the switch is turned off. The predetermined second water level is not particularly limited, but is preferably 10 to 30 cm, for example, 20 cm, from the viewpoint of reliably detecting a drop in the water level. The predetermined second water level may be a water level lower than the first water level. When the float switch 4 detects that the water level in the rainwater manhole 7 has fallen below the predetermined second water level, it also means that the float switch 4 is no longer able to detect water at the predetermined second water level in the rainwater manhole 7. The float switch 4 is preferably installed in the rainwater manhole 7 located within a predetermined distance from the pump 2, the balloon 1, or the waterstop 3 so that the water level in the rainwater manhole 7 can respond to conditions such as heavy rain at the location where the device 10 is installed. The predetermined distance is not particularly limited, but is preferably 1 to 100 m, and may be, for example, 10 m or 50 m.

[0015] There are no particular limitations on the type of rainwater pit 7, as long as it can collect liquid such as rain that enters through an opening (not shown). The bottom of the rainwater pit 7 may be installed at a position higher than the road surface, at the same height as the road surface, or at a position lower than the road surface.

[0016] There are no particular limitations on the lamp 5, as long as it lights up when the device 10 is operating or when the waterstop 3 is vertical to a horizontal plane. When the lamp 5 lights up, it can notify that the device 10 is operating.

[0017] The device 10 functions as follows. A case will be described in which heavy rain occurs and the water level in the storm water manhole 7 reaches a predetermined first level. When the float switch 4 detects that the water level in the storm water manhole 7 has reached the predetermined first level, the electric circuit (not shown) turns on, and the pump 2 and lamp 5 are activated. When the pump 2 starts, air is sent into the balloon 1 through the pipe 6, causing the deflated balloon 1 to expand. As the balloon 1 expands, the waterstop 3 installed above the balloon 1 is pushed up by the expanding balloon 1 via a hinge attached to the waterstop 3, gradually shifting from a horizontal position to a position perpendicular to the horizontal plane (see Figure 2(b)). The waterstop 3, which has shifted to a position perpendicular to the horizontal plane, prevents water from the road surface from flowing into areas lower than the road surface. When the heavy rain ends and float switch 4 detects that the water level in storm water manhole 7 has fallen below a predetermined second level, the electrical circuit turns off, pump 2 and lamp 5 stop, and air is released from balloon 1. As the air is released and balloon 1 deflates, waterstop 3 transitions from a vertical position relative to the horizontal surface to a horizontal position (see Figure 2(a)). In this way, float switch 4 detects the water level in storm water manhole 7 and switches the on / off state of the electrical circuit, automatically preventing water from the road surface from entering underground, etc., during heavy rain.

[0018] Although the present invention has been described above with reference to the embodiments, the present invention is not limited to the above embodiments and can be modified in various ways. For example, although each component has been specifically described in the above embodiments, not all of the components may be included, and other components may be included.
