Description

  The present invention relates to a water leakage treatment apparatus that receives liquid that has dripped from a pipe that supplies liquid that drops from the ceiling of a factory building or liquid material that is used in a factory or the like.

  Conventionally, in order to protect articles placed in the room from liquid dripping from the ceiling structure, a waterproof plate ("drain pan" in the present invention) is suspended directly under the ceiling structure and received by this waterproof plate. There has been proposed a method in which a water droplet is dropped and collected on a gutter for a beam provided on the beam, and further, this water drop is collected by flowing it to a surrounding gutter provided on a column for drainage (see, for example, Patent Document 1). .

  Moreover, as a general example, as shown in FIG. 16, the drain pan 1 which processed the both ends of sheet metal into the L shape is provided in the lower part of the piping which supplies the liquid material and various solutions in a building.

  In the state shown in the figure, the liquid leaking from the pipe 2 (not shown) is received by the drain pan 1, so that it is possible to prevent the leaked liquid from being applied to the article arranged at the lower part of the pipe 2.

Further, conventionally, there has been known a method in which a strip-shaped water leakage sensor is attached to the pipe itself to detect the water leakage in the pipe in real time (for example, see Patent Document 2).
JP 59-98943 A JP 11-6781 A

  However, the above conventional techniques have the following problems.

  That is, when a small amount of liquid drops or leaks, the liquid spreads on the drain pan because of the surface tension of the liquid because the drain pan that receives the liquid is flat.

  In other words, it will stay in place, and in some cases, it may even evaporate as it is.

  Therefore, for example, when the cracks in the concrete shown in the prior art and the damage to the piping are relatively minor, the amount of liquid that leaks is small, so it is not possible to secure the amount of liquid necessary to flow out on the drain pan. As a result, there was a problem that liquid leakage could not be found at an early stage.

  In addition, since the above-described sheet metal is made in a special order for each project in a building such as a factory, for example, when the equipment layout in the building is changed, the equipment layout is changed to that equipment layout. It was to be recreated accordingly.

  As a result, if you try to change the layout freely, you will not be able to use the drain pan that was used in the past, and conversely, if you stick to the use of the drain pan that has been used in the past, there will be restrictions on the layout change that was originally intended. Had the problem of becoming.

  In addition, when priority was given to changing the layout, which was the original purpose, the drain pan that had been used in the past was no longer needed and was discarded, while the cost and time required to make a new drain pan were required. .

  Furthermore, in the technique described in Patent Document 2, it is necessary to provide a water leakage sensor in each pipe, and water leakage sensors corresponding to the number of pipes to be installed are required.

  In addition, when the pipe length is long, it is difficult to specify where the water leak has occurred, and even if a leak or water leak is noticed, it takes time to repair the leak.

  Therefore, the present invention solves such a problem, and by constituting the drain pan with a corrugated plate made of a transparent or translucent transparent material, it is possible to flexibly cope with a layout change, and for ceilings and piping. The present invention provides a water leakage treatment device that enables early detection when a problem occurs.

  In order to achieve the above object, the present invention comprises a drain pan made of a corrugated plate in which a crest and a trough are continuously coupled via an inclined portion, and a support that supports the drain pan at a predetermined position. Is formed of a transparent or translucent transparent material.

  By adopting this configuration, even if a small amount of liquid leaks from cracks or damage in the ceiling or piping, the liquid that has fallen on the drain pan slides on the slope and gathers in the valleys, making it easier to form large drops. Is.

  Moreover, when the flow path is constructed using a plurality of drain pans, even if the layout is changed in the installed facility, the water leakage treatment device can be easily recombined or rearranged.

  According to the water leakage treatment apparatus of the present invention, even with a small amount of liquid leaking from the ceiling or piping, it becomes easy to form a large droplet by the liquid sliding on the inclined portion, and it is easy to construct a flow flowing on the drain pan.

  In addition, since transparent or translucent transparent materials are used, the drain pan can be seen from below the drain pan, and the state of the top of the drain pan such as the ceiling and pipes can be visually confirmed, so that the location of the fault and the situation can be grasped. This makes it easier to arrange the necessary actions for repair.

  In addition, since it is possible to easily cope with the layout change of the installed facility, it is possible to minimize the drain pan to be discarded without restricting the layout design.

Embodiments of the present invention
A drain pan made of a corrugated plate in which a mountain part and a valley part are continuously coupled via an inclined part,
And a support for supporting the drain pan at a predetermined position, and the drain pan is formed of a transparent or translucent transparent material.

  By adopting this configuration, slight damage occurs to the ceiling and piping, and even in the early stage where a small amount of liquid leakage occurs, the liquid that has dropped on the inclined part gathers at the bottom of the inclined part to form a large drop, It means that the liquid can flow easily.

  Moreover, since a transparent or translucent transparent material is used, it is possible to check the state of the ceiling and piping through the drain pan.

  As a result, it is possible to prompt the worker near the damaged part to notice the occurrence of an abnormality.

  In another embodiment of the present invention, one end of an inclined portion formed in a plane is joined to form a substantially V-shaped portion, and a drain pan in which a plurality of substantially V-shaped portions are joined together, And a support for supporting the drain pan, and the drain pan is formed of a transparent or translucent transparent material.

  By adopting this configuration, it is easy to make a large drop at the bottom of the substantially V-shaped portion by sliding down the inclined portion even with a small amount of liquid that has dropped.

  Furthermore, in another embodiment of the present invention, a crest or trough formed in a plane between the substantially V-shaped portions adjacent to the drain pan or between the inclined portions constituting the substantially V-shaped portion. At least one of these is provided.

  With this configuration, by providing a flat surface in the horizontal direction, the visibility is particularly improved when the opposite side of the drain pan is viewed through the drain pan.

  In particular, when a flat surface is provided in the valley portion, a narrow portion is not formed between the inclined portion and the inclined portion, and it is possible to suppress the occurrence of clogging that hinders the flow path of the leaked liquid.

  Furthermore, in addition to the above-described embodiment, the embodiment of the present invention is provided with a water leakage sensor that detects water leakage in at least one of the valleys.

  In other words, when water leakage generated on the ceiling or piping falls on the drain pan, the liquid slides down on the inclined portion provided on the drain pan, forming a large drop.

  As a result, because the large droplets that have become easy to flow through the valleys due to the above-described configuration, liquid leakage detection by the water leakage sensor is facilitated, and it is easy to find that a defect has occurred in the ceiling or piping.

  In another embodiment of the present invention, a water leak sensor is provided at a predetermined interval on a drain pan to be laid, and the presence or absence of water leak is detected at a predetermined interval.

  By adopting this configuration, it is possible to monitor whether or not water leakage has occurred in units of blocks at predetermined intervals regardless of the length of the pipe to be laid.

  As a result, if the leak sensor detects a leak, it can detect where in the pipe it occurred in blocks, so that no matter how long the pipe is, the fault location can be narrowed down to a predetermined range. This makes it possible to easily identify a failure factor such as a crack.

  Therefore, repair work such as repair and replacement can be carried out promptly.

  Next, another embodiment of the present invention is provided with a gutter for collecting water leaked on the drain pan at one end side end of the drain pan installed so that one end is horizontally lower than the other end. A water leakage sensor is provided in

  By adopting this configuration, when water leaks, drops flow into the bottle, so that a leak sensor can be provided in the bottle to detect the occurrence of water leak.

  That is, even if a plurality of pipes are installed, since the occurrence of water leakage can be detected by providing at least one water leakage sensor on the ridge, the installation of the water leakage sensor and its peripheral devices can be reduced.

  Next, in another embodiment of the present invention, adjacent drain pan connections are overlapped so that the upstream side is higher than the downstream side so that the liquid leaked from the pipe flows from upstream to downstream. Is.

  Specifically, one end of the drain pan to be laid is placed horizontally below the other end so that the liquid flowing on the drain pan group flows from upstream to downstream, and the other end of the downstream drain pan and one end of the upstream drain pan Are arranged to overlap each other.

  By connecting the drain pan in this manner, when the leaked liquid flows from the upstream to the downstream, the liquid does not flow into the gap of the connecting portion, so the liquid leaks from the connecting portion. There is nothing.

  That is, by arranging in this way, the liquid leakage from the part does not occur even if no special device is applied to the connection part between the drain pans.

  In addition, it is possible to install a water leakage treatment device corresponding to various layouts by rearranging the drain pan of a predetermined length.

  Furthermore, in another embodiment of the present invention, adjacent drain pans are laid so as to have a predetermined angle in the horizontal direction, and the end of the upstream drain pan is disposed above a predetermined trough of the downstream drain pan. It is.

  By installing in this way, when water leaks, drops flow into a predetermined valley, and therefore, if a water leakage sensor is provided in this predetermined valley, the occurrence of water leakage can be detected.

  That is, even if a plurality of pipes are installed, since the occurrence of water leakage can be detected by providing at least one water leakage sensor in a predetermined valley, the installation of the water leakage sensor and its peripheral devices can be reduced. .

  Embodiments of the present invention will be described below with reference to the drawings.

Example 1
FIG. 1 is a perspective assembly view when a corrugated plate in which substantially V-shaped portions are continuously connected is used, and FIG. 2 is a plan view when the corrugated plate is used.

  As shown in the figure, first, a support comprising a drain pan base 6 (6a to 6c) on which a drain pan 5 (5a to 5c) is placed and a hanging metal fitting 7 (7a to 7c) for a required layout (not shown). A tool 8 is provided at a predetermined position.

  Drain pan 5a, drain pan 5b,... Are installed on the suspended supports 8a to 8c so as to connect the respective supports.

  At this time, one end of the drain pan 5a at the most downstream side is provided with a ridge 9 for receiving the flowing liquid, and the other end is provided with a slight inclination so as to be above the one end in the horizontal direction. .

  Similarly to the drain pan 5a, the drain pan 5b provided adjacent to the upstream side of the drain pan 5a is also arranged such that one end corresponding to the downstream side is horizontally lower than the other end on the upstream side. At this time, if a predetermined amount (for example, 10 cm) of overlap between the drain pan 5a and the drain pan 5b is secured, a natural flow from the drain pan 5b to the drain pan 5a without flowing back from the drain pan 5a to the drain pan 5b when the liquid flows. Can be formed.

  Similarly, the drain pan 5c... Is sequentially connected in the same manner, and a water leakage treatment device according to a necessary layout is provided.

The plan view is shown in FIG.
The arrows in the figure indicate the liquid flow generated on the drain pan.

  That is, a flow is formed in order of 10a, 10b, 10c, and 10d from the upstream side.

  The liquid flows 10a to 10d flow into the trough 9, and are connected from the drain port 11 of the trough 9 to the water leakage detection means 14 provided in the nearby column 13 through the water distribution pipe 12.

In the figure, 15a and 15b are overlaps of the drain pans.
By sufficiently securing the overlaps 15a and 15b, it is possible to prevent the flowing liquid from flowing backward without taking any special measures.

  In actual construction, workability is improved when the L-shaped guide 16 as shown in FIG. 3 is provided on the supports 8a and 8b.

  It is assumed that a layout change has occurred in the facility thus installed.

  In response to the change in the layout, as shown in FIG. 4, supporters are installed as in 8a to 8e. And drain pan 5a-5d is arrange | positioned in order from the downstream on each support tool 8a-8e.

  In this way, it is possible to immediately respond to the layout change.

  As shown in FIG. 3, after the hanging bracket 7 of the support tool 8 is hooked on the hanging bracket locking tool 17, the hanging bracket locking tool 17 may be fixed to the ceiling of the building. It may be locked to a pipe (not shown).

  Moreover, it is also possible to arrange as shown in the figure by providing a fixture (not shown) directly on the ceiling of the building and connecting to this fixture.

The details of the drain pan used in the water leakage treatment apparatus that can be laid in this way will be described.
FIG. 5 shows a cross-sectional view of a drain pan in which substantially V-shaped portions are connected.

As shown in the figure, the substantially V-shaped portion 21 is continuously joined to form the drain pan 20.
The drain pan 20 is disposed on the drain pan base 6 via an L-shaped guide 16 and is fixed at a predetermined position by a hanging metal fitting 7.

  A pipe 22 (22a, 22b) is provided above the drain pan 20, and a liquid according to various purposes flows through the pipe.

  Now, assume that the pipe 22a is damaged in the pipe 22 and a small amount of liquid leakage occurs.

  The leaked liquid 23a falls on the inclined portion 20a of the drain pan 20 (23b), slides on the inclined portion 20a, and moves to the valley portion 20b.

  The liquid that has moved to the valley 20b is accumulated and becomes larger (23c), and flows out on the drain pan 20 when it exceeds a predetermined amount.

  The subsequent flow is as described above.

  In such a drain pan 20, when the angle A of the substantially V-shaped portion 21 is made more acute, the shape becomes a steep V-shape, and when liquid leakage occurs from the pipe 22a, the liquid 23b that is the droplet is discharged. The effect that it becomes easy to collect can be expected.

  As a result, it is possible to collect the amount of liquid 23c that flows out more quickly.

  On the other hand, if the angle A of the substantially V-shaped portion 21 is made to be obtuse from a right angle, when an operator (not shown) passes through the vicinity, when the pipes 22a and 22b are viewed through the drain pan 20, Since the plane of the inclined portion 20a is nearly horizontal, visibility is improved.

  As a result, when a crack or damage occurs in the ceiling or piping, it can be expected to find the damaged part more quickly.

  As the material of the drain pan 20, polycarbonate is optimal from the viewpoints of workability at the time of laying, easy availability of materials, etc. while ensuring visibility. Other materials such as vinyl chloride and acrylic are preferred.

  As described above, when the drain pan 1 is configured by sheet metal as in the past, it was not found that the pipes 22a and 22b were damaged unless the liquid 23c leaked to the leak detector 14 reached. .

  However, when the drain pan 20 is formed of a transparent or translucent permeable material as in the present invention, for example, the liquid 23c can be confirmed by direct viewing of an operator (not shown) passing by. In addition, in an environment where sufficient light can be secured from the upper part, it is possible to expect to be noticed by the shadow created by the liquid 23c.

  That is, by using a transparent or translucent transparent material for the drain pan 20, damage or cracks on the pipes or ceiling, etc., for example, streaks on the pipe surface, signs of cracks appear, or When the pipe surface is covered with a heat insulating material or the like, it is possible to confirm the occurrence of an abnormality at the stage where the surface is blotted.

  As a result, the pipe can be repaired before a large amount of liquid leaks, and damage can be minimized.

(Example 2)
Next, an embodiment when a water leakage sensor is provided will be described.

  FIG. 6 shows a cross-sectional view when a water leak sensor is used, and FIG. 7 shows a perspective view when another water leak sensor is used.

  In FIG. 6, 30 is a water leak sensor, and 31 is a detector that performs arithmetic processing to notify the administrator of water leak detection information detected by the water leak sensor 30.

  As shown in the figure, the water leakage sensors 30 are respectively arranged in the main valleys 20b below the pipes 22a and 22b.

  In this state, for example, it is assumed that a failure such as a crack occurs in the pipe 22a and water leakage occurs.

  The leaked liquid 23a falls on the drain pan 20, slides down on the inclined part 20a (23b) and collects in the valley part 20b, and forms a liquid 23c which is a large droplet.

  Since the water leakage sensor 30 is provided on the valley 20b through which the liquid 23c that has become easy to flow flows, the occurrence of water leakage can be detected promptly.

  At this time, since the drain pan 20 is made of a permeable material, if the pipes 22a and 22b are seen through the drain pan 20, a defective portion can be easily identified.

  Furthermore, if the strip-shaped water leakage sensor 32 (32a, 32b, 32c) as shown in FIG. 7 is used, the presence or absence of water leakage can be monitored in units of blocks at predetermined intervals such as 5a to 5c. .

  That is, the drain pan is laid with an inclination so that water flows from the drain pan 5c toward the drain pan 5a.

  In this state, it is assumed that a signal notifying that water leakage has occurred is transmitted from the water leakage sensor 32b to the detector 31. On the other hand, from the water leakage sensor 32c, assuming that no signal indicating water leakage has occurred, it can be easily determined that water leakage has occurred in a block called the drain pan 5b.

  Then, if a pipe (not shown) is visually observed through the drain pan 5b made of a permeable material, it is possible to easily confirm what kind of trouble has occurred in which part.

  The above-mentioned water leakage monitoring in units of blocks is more effective when the piping is long than the prior art and can be realized with fewer water leakage sensors than before, so that the cost required for installation can be suppressed.

  In the above description, the band-shaped water leakage sensor is used. However, it goes without saying that the same effect can be obtained even if the water leakage sensor used in FIG. 6 is used.

  Moreover, as shown by 33 in the figure, if a water leakage sensor 33 is provided in the trough 9, even if a malfunction such as disconnection occurs in the water leakage sensors 32a to 32c provided on the drain pans 5a to 5c, The sensor 33 can detect the occurrence of water leakage in an auxiliary manner.

(Example 3)
Furthermore, another embodiment when a water leakage sensor is provided will be described.

  FIGS. 8 and 9 are plan views in the case where the end of the upstream drain pan is disposed above a predetermined valley of the downstream drain pan and a water leakage sensor is provided in the predetermined valley.

  In FIG. 8 and FIG. 9, the same reference numerals are given to those having the same functions as those described in the first and second embodiments, and the description thereof uses the first and second embodiments. In the figure, 30 is a water leakage sensor.

  As shown in the figure, the downstream end of the drain pan 5c is provided on a predetermined valley 20h of the drain pan 5b on the downstream side.

  By adopting this configuration, for example, water leaked from a pipe (not shown) disposed above the drain pan 5d forms a droplet 34, and passes through the liquid flows 10a to 10b and 10c to the drain pan. It is guided to the valley 20h of 5a and detected by the water leakage sensor 30 on the way to the trough 9.

  As shown in FIG. 9, the water leakage sensor may be arranged with only 33 instead of 30.

  In this way, by consolidating the liquid that has fallen on a certain drain pan into a predetermined valley of the drain pan on the downstream side, even when installing a plurality of pipes, the position where the leak sensor is installed is devised. This makes it possible to detect water leakage with a small number of water leakage sensors.

  As a result, the number of water leakage sensors can be reduced, and the number of man-hours required for the installation can be reduced, so that the construction period for constructing the facility can be shortened.

  Moreover, even after the facility is in operation, monitoring is easy because the number of leak sensors to be managed is small.

  Next, in FIG. 10, a gutter that collects the water that has flowed over the drain pan is provided at one end of the drain pan that is installed so that one end is horizontally below the other end, and a water leakage sensor is provided on this gutter. A plan view and a side view are shown.

  First, the scissors 9a and 9b shown in the figure will be described.

  These troughs 9a and 9b are provided with drains 35a and 35b, respectively, as drains to the downstream side, and the troughs 9a and 9b themselves are inclined so that the liquid gathers toward the drains 35a and 35b. If there is.

Now, as shown in the figure, it is assumed that water leaks from a pipe arranged above the drain pan 5b.
The liquid that has fallen on the drain pan 5b becomes droplets 34, which become liquid flows 10a and 10b, and flow into the basket 9a.

  The flowed-in liquid flows toward the drain outlet 35b according to the shape of the ridge 9a (10c). If a water leakage sensor 33a is provided in the vicinity of the drain port 35b, the occurrence of water leakage can be detected when a liquid flows into the tub 9a.

  Then, the liquid that has flowed out onto the drain pan 5a through the drain port 35b flows into the basket 9 while constructing the liquid flows 10d to 10f.

  Thereafter, the liquid moves in the tub 9 toward the drain port 11 and is discharged from the drain port 11 to the outside.

  At this time, since the water leak sensor 33b provided in the ridge 9b is on the upstream side of the water leak occurrence location, no reaction is shown.

  That is, since the water leakage sensor 33b does not react and the water leakage sensor 33a reacts, it can be estimated that water leakage has occurred in the pipe portion above the drain pan 5b.

  That is, by using this embodiment, even when a large number of pipes are installed, it is possible to accurately detect in which block water leakage has occurred with a small number of water leakage sensors.

Example 4
Next, another embodiment in which the cross-sectional shape of the drain pan is changed will be described.

  FIG. 11 to FIG. 13 show an embodiment in which peaks or valleys constructed in a plane are provided between adjacent substantially V-shaped portions or inclined portions constituting the substantially V-shaped portion.

  First, the drain pan 25 shown in FIG. 11 is obtained by providing a flat surface on the crest 20 d of the adjacent substantially V-shaped portion 21.

  The feature of this embodiment is that, in addition to the ease of collecting the liquid 23c described in the first embodiment, a horizontal plane is provided at a position close to the pipes 22a and 22b.

  That is, when a problem occurs, a plane with little bending is in the vicinity of the pipes 22a and 22b, so that an operator can easily see the pipes 22a and 22b through the drain pan 25 and find a damaged part.

  Next, the drain pan 26 shown in FIG. 12 is provided with a plane between the valley portions of the adjacent substantially V-shaped portions 21.

  The feature of the present embodiment is that, in addition to the ease of collecting the liquid 23c described in the first embodiment, a narrow shape is not generated in the valley 20c between the substantially V-shaped portions 21.

  That is, when the drain pan 26 is arranged as shown in the drawing, the flat surface of the valley 20c becomes wide, and the valley 20c is not clogged even if dust or dust accumulates.

  Therefore, if the location of the pipes 22a and 22b is not frequently checked or a place where maintenance work is difficult, dust and dust are not trapped.

  As a result, the flow of the liquid 23c is not hindered, and a smooth flow of the liquid 23c can be ensured.

  Next, the drain pan 27 shown in FIG. 13 is provided with a flat surface at both ends of the inclined portion 20a, and has a U-shaped cross-section with one peak 20d and the other valley 20c.

  This configuration has both effects of the embodiments shown in FIGS. 11 and 12 described above.

  That is, since the plane that forms the peak portion 20d is disposed in the vicinity of the pipes 22a and 22b, when an operator (not shown) looks through the drain pan 27 from below, the pipes 22a and 22b are easy to see. If a sign such as a blur occurs, it is easy to find.

  In addition, since the valley 20c is configured as a flat surface, clogging of the valley 20c due to accumulation of dust and dust is less likely to occur.

  As shown in FIG. 14, it goes without saying that the same effect can be obtained even if the peaks and valleys connecting adjacent inclined portions 20a have shapes other than those described above.

(Example 5)
Furthermore, as another embodiment, a case of a drain pan with a round corrugated plate having a curved cross-sectional shape will be described.

  The drain pan 29 shown in FIG. 15 is obtained by joining the inclined portion 20e at the peak portion 20f and the valley portion 20g with a C-shaped curve.

  The feature of this embodiment is that it does not have a horizontal plane, so that even if the leaked liquid 23a falls on any position on the drain pan 29, the liquid collects in the valley 20g of the drain pan 29 (23c), Since a narrow portion does not occur in the portion 20g, clogging of the valley portion 20g due to accumulation of dust and dust is less likely to occur.

  The present invention can be expected to obtain an equivalent effect in a place where piping is laid, such as a factory or an underground passage.
