Summary of the Invention

Problems to be Solved by the Invention

[0004] It is difficult to identify the location where water leakage occurs, such as on the ceiling of the station building or the underground passage of the station. Therefore, there is a need to install water leakage treatment devices such as curing sheets for a long time. In addition, water leakage is not always eliminated by repair, and even if the water leakage stops once, it is not uncommon for the water leakage to occur again after a while, resulting in an intermittent water leakage phenomenon.

[0005] Therefore, when an operator checks the water leakage location, even if it is confirmed that the water leakage has disappeared, there is a possibility that the water leakage has temporarily stopped. Therefore, the curing sheet is not immediately removed, and the water leakage treatment device is installed for a while and observed continuously. As a result, the installation of the curing sheet and the like over a long period of time is required, and it becomes even more difficult to determine when to end the installation.

[0006] Therefore, it is required to be able to easily confirm the elimination of water leakage and the like after installing devices such as a curing sheet. [Means for solving the problem]

[0007] One embodiment of the present invention is a leak detection device that can be configured as a complete leak treatment device, together with a liquid receiving sheet (e.g., a protective sheet) that can be freely installed on a ceiling or wall, and a tubular member (such as a flexible hose or pipe) whose end is connected to the discharge port of the liquid receiving sheet. The leak detection device is configured to be detachably connected to the tubular member and can be incorporated into the complete leak treatment device as needed.

[0008] The liquid receiving sheet and tubular members can be installed in a manner that suits the location of the leak, for example, by attaching and securing them to the ceiling or wall with tape. The leak detection device can be placed in a visible location depending on the installation of these components.

[0009] The leak detection device of the present invention comprises an inlet into which liquid flows, a bag capable of storing the liquid flowing in from the inlet, and an outlet for discharging the stored liquid (hereinafter referred to as stored liquid). For example, the inlet can be connected to a sheet-side tubular member, and the bag is configured to store the liquid that flows in rather than simply discharging it.

[0010] The bag is constructed in such a way that the stored liquid is visible. There are various ways to construct the bag to make the stored liquid visible. For example, the bag can be made transparent or semi-transparent so that leaks can be seen. The bag can also be made from various materials. For example, it can be made from a material (such as polyvinyl chloride) that can change shape depending on the amount and depth of the stored liquid. The shape of the bag is arbitrary; for example, it can be made into a horizontally elongated rectangle or a rectangular prism based on a square shape. The bag can be configured so that the whole or part is exposed, or it can be enclosed in a case or covered with a material that allows the stored water to be seen, as long as the stored liquid is visible.

[0011] The bag can be configured to store incoming liquids such as leaked water, while also allowing them to be discharged from the outlet depending on the passage of time or the amount of leakage. For example, the bag can be configured so that when the stored liquid exceeds a predetermined amount, the stored liquid is discharged from the outlet. With the sheet-side tubular member connected to the inlet, a storage space can be formed inside the bag to prevent the stored liquid from flowing downward from the outlet when it is below a predetermined amount.

[0012] The bag can be configured with an inlet and an outlet at the top and bottom of the bag, respectively. The bag only needs to be airtight to prevent the stored liquid from leaking out from anywhere other than the outlet. The end of a tubular member such as a flexible hose or pipe (hereinafter referred to as the discharge-side tubular member) that can be connected to the outlet, or the outlet itself, can be configured to be located at a predetermined height above the bottom of the bag. For example, the position (height) of the end of the discharge-side tubular member that is inserted into the internal space of the bag can be determined according to the volume of stored liquid. For example, the outlet can be located away from the position opposite the inlet.

[0013] The bag can be equipped with a zipper (fastener) that opens and closes to allow the stored liquid to be discharged. For example, the zipper can be installed between the inlet and outlet of the bag. If the bag is rectangular, the zipper can be installed along the side. The zipper can be configured in various ways; for example, it can be a tight-fitting type of wire zipper in which the convex part fits into the concave part.

[0014] The bag can be equipped with markings to indicate the level of liquid storage. The markings can be in various forms; for example, multiple lines can be arranged vertically (in the depth direction) along the liquid surface.

[0015] A set of leak treatment equipment according to one aspect of the present invention comprises the above-mentioned leak storage detection device, a liquid receiving sheet that can be installed according to the location of the leak, a sheet-side tubular member that connects the inlet of the leak detection device to the outlet of the liquid receiving sheet, and an outlet-side tubular member that connects to the outlet of the leak detection device.

[0016] A method for installing a set of liquid leakage treatment devices, which is an aspect of the present invention, includes installing a liquid receiving sheet according to the liquid leakage location, connecting one end of a sheet-side tubular member to the discharge port of the liquid receiving sheet, and connecting the liquid leakage detection device to the other end of the sheet-side tubular member.

Effects of the Invention

[0017] According to the present invention, after installing devices such as a curing sheet, it is possible to easily confirm the elimination of water leakage and the like.

Modes for Carrying Out the Invention

[0019] Hereinafter, a set of water leakage treatment devices according to the present embodiment will be described with reference to the drawings.

[0020] A set of water leakage treatment devices is a set of devices that temporarily guide water leakage to a drainage ditch or a bucket when rain leakage occurs on the ceiling C or the wall surface M in a station building or an underground passage. It includes a water leakage detection device 10, a curing sheet 100, and pipes 120 and 130. The curing sheet 100 is composed of, for example, a flexible sheet made of synthetic resin and can be attached to the ceiling C. A connection pipe 110 for discharging water leakage is provided at the central portion of the curing sheet 100.

[0021] The pipe 120 can be connected to the connection pipe 110 provided on the curing sheet 100, and the water leakage received by the curing sheet 100 flows out into the pipe 120 through the discharge port 110N of the curing sheet 100. The pipes 120 and 130 are composed of flexible pipes made of, for example, vinyl chloride here, and can be attached and fixed to the ceiling C or the wall surface M with tape or the like.

[0022] The water leakage detection device 10 is disposed between the pipes 120 and 130, temporarily stores the water leakage flowing into the pipe 120, and discharges the stored water leakage to the pipe 130. The pipe 240 is also made of a flexible material like the pipe 120, can be attached to the wall surface M and fixed.

[0023] When the operator finds the water leakage point, the operator transports and installs the set of water leakage treatment devices to the water leakage site. Specifically, the curing sheet 100 is attached to the ceiling C or the wall surface M with tape or the like so as to cover the water leakage point. Also, one end 120A of the pipe 120 is connected to the connecting pipe 110 of the curing sheet 100, and the other end 120B of the pipe 120 is connected to the water leakage detection device 10. Further, one end 130A of the pipe 130 is connected to the water leakage detection device 10, and the other end 130B is disposed in a bucket or a drainage ditch or the like.

[0024] FIG. 2 is a plan view of the water leakage detection device 10 as viewed from the front side. FIG. 3 is a side view of the water leakage detection device 10.

[0025] The water leakage detection device 10 includes a bag body 40 capable of storing water leakage. The bag body 40 is made of a flexible material and has a three-dimensional shape with a depth (depth, width). On the other hand, in a state where no water leakage flows in, it has a deflated shape. Here, the bag body 40 uses vinyl chloride as the material. The bag body 40 has a shape in which a rectangular parallelepiped shape is recessed from both side surfaces in a state where no water leakage is contained, and it is deformed when force is applied by hand.

[0026] The shape of the bag body 40 changes according to the amount of water leakage stored in the internal space S. As the storage amount increases, it changes from a deflated shape to a rectangular parallelepiped shape. In FIGS. 2 and 3, the shape when the internal space S of the bag body 40 is filled with liquid is shown.

[0027] The bag body 40 is provided with an inlet 20 at the top 40U and an outlet 30 at the bottom 40B. The end 120B of the pipe 120 is inserted into the inlet 20A of the inlet 20, thereby spatially connecting the pipe 120, the leak detection device 10, and the internal space S of the bag body 40.

[0028] The outlet portion 30 of the leak detection device 10 is located on the side of the inlet portion 20 (upper side) than the bottom portion 40B of the internal space S of the bag body 40, and is formed to straddle the recess 40K formed near the corner of the bottom portion 40B of the bag body 40 and the internal space S. While the outlet portion 20 is located along the central line (see symbol C) of the bag body 40, the location of the outlet portion 30 is off-center from the central line C, i.e., from the position opposite the inlet portion 20. The inlet portion 20 and the outlet portion 30 are made of the same material as the bag body 40.

[0029] The end 130A of the pipe 130 is screwed into a male thread formed on the inner surface 30N of the tubular outlet section 30 and fixed so as to protrude upward from the outlet section 30 (see Figure 1). In the bag body 40, the end 130A of the pipe 130 is fixed at a predetermined height h from the bottom 40B of the bag body 40.

[0030] A fastener 42 is provided on the surface side of the bag body 40, running along the lateral direction (longitudinal direction) of the bag body 40. The fastener 42 can be opened and closed to allow the stored leaked water to be discharged, and when closed, it seals the internal space S to prevent the stored water from leaking out. In this case, the fastener 42 is made of an adhesive hook-and-loop fastener with convex and concave ridges that fit together, and is integrally formed with the bag body 40.

[0031] The exposed bag 40 is colorless and transparent, allowing the stored water to be visually inspected. Furthermore, a scale 50 indicating the amount of stored water is provided on the surface of the bag 40. Here, the scale is marked or printed between the fastener 42 of the bag 40 and the bottom 40B of the bag 40, at predetermined intervals in the depth direction (vertical direction).

[0032] By placing such a leak detection device 10 between the pipes 120 and 130, it is possible to confirm whether or not a leak occurred previously after the installation of the leak treatment equipment set.

[0033] In cases of water leaks in underground train stations, it is difficult to pinpoint the source of the leak and to verify the effectiveness of repairs. Therefore, in some cases, leak treatment equipment is left in place for extended periods (e.g., several months to several years). Furthermore, leaks do not always occur continuously; they can be intermittent and irregular. On the other hand, it is virtually impossible for workers to constantly monitor the leak situation.

[0034] As described above, the leak detection device 10 can store leaked water in the internal space S until the amount of stored water exceeds a certain amount, that is, until it reaches the end 130A of the pipe 130 that has been inserted into the outlet 30 and reached the internal space S of the bag body 40. In other words, by installing the leak detection device 10 with the inlet 20 on the upper side and the outlet 30 on the lower side, a storage space is formed between the end 130A of the pipe 130 and the bottom 40B of the bag body 40. In Figure 1, the stored water is indicated by the symbol W.

[0035] Because the outlet section 30 is offset from the position opposite the inlet section 20, it is possible to prevent leaked water from flowing out directly from the outlet section 30. In addition, because the outlet section 30 is connected and fixed to the pipe 130 by a screwdriver, the outlet section 30 and the pipe 130 are in close contact, and the position of the end 130A of the pipe 130 can be adjusted, that is, the height h from the bottom 40B of the bag body 40 can be adjusted.

[0036] As mentioned above, the water storage detection device 10 is transparent, allowing the stored water to be visually identified. Even if water leaks intermittently and irregularly, workers can confirm that the leak has not yet been resolved by checking the stored water.

[0037] Furthermore, the worker can check the degree of leakage water accumulation using the 50 mark on the scale. By quantitatively measuring the amount of leakage water accumulated using the 50 mark as a reference each time the check is performed, it is possible to determine whether the leak has stopped (no water accumulation detected, no change in leakage amount, etc.) or whether the leak has not been resolved (water accumulation detected, increase in leakage amount).

[0038] For example, in a situation where an existing leak repair system whose installation date cannot be confirmed is in place, installing the leak detection device 10 together with the pipes 120 and 130 allows for confirmation of whether or not the leak has been resolved, and makes it possible to remove the protective sheet that has been in place for a long period of time.

[0039] On the other hand, when the amount of stored leak water exceeds a certain level, the stored water flows out from the outlet section 30, preventing the internal space S of the leak detection device 10 from being filled with leak water and suppressing the leakage of stored water. Therefore, the leak detection device 10 can control the flow of leak water like a dam.

[0040] Furthermore, by opening and closing the zipper 42, the accumulated leaked water can be drained without removing the leak detection device 10. This allows for the draining of leaked water mixed with rust stains and other contaminants.

[0041] The bag body 40 is airtight to prevent the stored leaked water from leaking out, and because the bag body 40 is made of a flexible material, the installation height and orientation (tilt) can be determined according to the installation location of the leak treatment equipment set. In particular, because the pipes 120 and 130 are flexible components, the worker can position the leak detection device 10 at the desired location according to the leak location, so the orientation of the bag body 40 does not necessarily maintain a horizontal orientation and may be tilted. However, due to the flexible structure of the bag body 40, which allows for the storage of a certain amount of stored water, the leak detection function can be performed regardless of the installation location and position (orientation).

[0042] The characteristics of the shape and material of the bag body 40 are not limited to those described above. Regarding the connection configuration between the outlet section 30 and the piping 130, the outlet section 30 may be connected with the outlet section 30 on the upper side and the end 130A of the piping 130 on the lower side. Furthermore, the bag body 40 can be constructed as a separate unit from the inlet section 20 and the outlet section.

[0043] The bag 40 can also be made semi-transparent. It should be made of a permeable material that allows the stored water to be seen. For example, it could be made of a colored, permeable material that obscures rust stains. Furthermore, only a portion of it could be made transparent. Any configuration that allows the stored water to be seen is acceptable.

[0044] In the above-described bag 40, the stored water is configured to flow out naturally due to gravity once it exceeds a certain amount. However, it may also be configured to be partitioned to prevent the stored water from flowing out, and to allow the water to flow out of the bag 40 when a certain level of pressure is applied.

[0045] The above-described water leak detection device 10 can be applied to ceilings, walls, and other parts of buildings other than train stations and underground passages. For example, it can be applied to hospitals, office buildings, factories, agricultural equipment such as greenhouses, and transport containers. Furthermore, it can be used in situations where liquids other than water leak out. [Explanation of Symbols]
