[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention basically comprises a water storage container, a starting siphon, a pipe-shaped member, a high water channel resistance portion, and a main siphon for discharging accumulated water in a space to be drained. It is an automatic drainage device.

[0009] In the above, the water storage container is a container for storing water from the outside such as rainwater, and is constituted by one container, and the upper part thereof is covered with a lid. Usually, at least a part of the lid needs to have a water-permeable hole for guiding rainwater or the like. In addition, the water storage container, when the water stored in it is allowed to flow out into the pipe-shaped member, coupled with the function of the high water channel resistance portion,
Since it is necessary to raise the water level at least temporarily to exceed the highest part (turning part) of the main siphon, its bottom needs to be positioned above the highest part of the main siphon. There is.

[0010] The water storage container may be covered with a cosmetic covering material that allows passage of rainwater or the like. Depending on the equipment surrounding the drainage target space to which the automatic drainage device of the present invention is applied, it may be better not to expose the water storage container and the like, and in such a case, as described above, the water storage container is It is meaningful to cover with a coating material for use. The cosmetic covering material can be configured in various forms depending on the properties of the target facility.

The water storage container does not have to be constituted by one container. For example, a rainwater receiving container that can receive external water such as rainwater,
It may be constituted by an airtight container communicating with the water supply so as to receive the water supply and having the starting siphon.

With this configuration, it is preferable that the facilities surrounding the space to be drained have a positional relationship in which it is difficult to obtain rainwater or the like, or that the water storage container is exposed to the vicinity as described above. In such a case, the rainwater receiving container is arranged in a place where rainwater or the like is easily obtained or a place where there is no problem in appearance even if it is installed, and the rainwater or the like is received with the rainwater and the like, It can be guided to a closed container.

It is suitable to provide a filter for preventing passage of foreign matter at the rainwater receiving port of the water storage container, that is, at the water-permeable hole formed in the lid for guiding rainwater or the like. This is particularly significant for protection of the high channel resistance section.

[0014] The starting siphon is a means for rapidly discharging the stored water that has reached a required amount in the water storage container. That is, when the starting siphon receives rainwater or the like in the water storage container and the amount of the stored water flows out of the stored water into the pipe-shaped member, at least one time in combination with the function of the high water channel resistance portion. Specifically, when the water level reaches an amount that can raise the water level beyond the highest part of the main siphon, this works to allow the stored water to flow out into the pipe-shaped member at once. The amount of water storage is the required amount.

[0015] The outflow of the stored water by the starting siphon does not start unless the level of the stored water in the water storage vessel exceeds the highest part (turning part) of the starting siphon and the inside thereof is filled with water. Therefore, it is necessary to set the capacity of the water storage container or the height of the highest part of the starting siphon so that the required amount can be secured when the water level is reached.

The pipe-shaped member is an elongated member for guiding the stored water flowing out of the starting siphon into the pipe-shaped member, and has an outflow end of the main siphon disposed therein. Since the outflow end of the main siphon is disposed therein, the lower part of the pipe-shaped member must naturally extend below the bottom of the space to be drained. Further, as described above, since the pipe-shaped member may be filled with water flowing out of the starting siphon until it exceeds the highest part of the main siphon, the upper part thereof is provided with the main siphon. The siphon must be extended to a height higher than the highest part of the siphon.

The high water channel resistance portion is inserted between a lower end of the pipe-shaped member and a discharge destination, and at least when the stored water rapidly flows into the pipe-shaped member through the starting siphon. By the time the outflow ends, the water level in the pipe-shaped member is made to exceed the highest part of the main siphon so that a high water resistance can be formed that can delay the discharge of the outflow water to the discharge destination. It is what was constituted.

[0018] Specifically, the high water channel resistance portion can be constituted by filling felt, glass fiber, or the like into the corresponding portion. In the case of such a configuration, the high channel resistance of the high channel resistance section always maintains the high channel resistance which does not fluctuate. As described above, the water in the water storage tank flows out of the starting siphon, and the water level in the pipe-shaped member rises to the highest part of the main siphon or more due to the high water channel resistance function, and the water in the main siphon is filled with water. Is satisfied, one important condition for starting drainage of accumulated water in the drainage target space is achieved.

As described above, when the water level in the pipe-shaped member rises, the water in the pipe-shaped member temporarily flows back into the space to be drained. Water is gradually drained from the high water channel resistance part, the water level gradually decreases, and reaches a level lower than the level of accumulated water in the space to be drained. Is satisfied, and the water is gradually drained similarly as the water level in the pipe-shaped member decreases.

Although the drainage is forced to be slow by the high water channel resistance portion, it is not particularly inconvenient unless the drainage speed is particularly required. Also, it may be used for applications where drainage speed is not required.

The high-water-path resistance section may be replaced with the above-described configuration,
The channel resistance can be configured to fluctuate. For example, normally, a high waterway resistance is maintained, but when the pipe-shaped member is filled with water through the starting siphon and its water level exceeds the highest part of the main siphon, the waterway rapidly increases. The low water resistance state is maintained until all the water in the pipe-shaped member and the space to be drained is drained, and when the drainage is completed, the state returns to the original high water resistance state. It is.

This can be realized, for example, by switching the resistance mechanism of the high water channel resistance portion using the weight or water pressure of the water when the water level exceeds the highest part of the main siphon. Can be.

With this configuration, a high-speed drainage speed can be obtained immediately after the start condition of the drainage operation for the main siphon is adjusted, so that a quick drainage operation can be performed.

The main siphon is a basic means for draining accumulated water generated in the space to be drained, the inflow end of which is opened at the bottom of the space to be drained, and the outflow end of which is connected to the outflow end. The opening is provided below the pipe-shaped member. The outflow end must be opened below the bottom of the space to be drained.

The draining operation of the main siphon is, as understood from the above, as described above,
Water flows into the pipe-shaped member, the water level of which rises above the highest part of the main siphon, and the main siphon is filled with water, so that it can be started.

It is appropriate to provide a filter for preventing foreign matter from passing through the inflow end of the main siphon. This is significant for the protection of the high water channel resistance portion, similarly to the filter for preventing the passage of foreign matter, which is provided at the rainwater receiving port of the water storage container. Since this filter is located in the space to be drained, if clogging occurs, manual maintenance may be troublesome. At this time, since the filter is backwashed, clogging does not usually occur.

Therefore, according to the automatic drainage device of the present invention, if water accumulates in the drainage target space for some reason, it may take some time to drain the water.
As will be described below, the water is reliably drained without any particular labor.

Since the water storage container is adapted to receive rainwater or the like, it flows into and is stored in rainy weather or the like. When the amount of the rainwater reaches a required amount, that is, when the water level in the water storage container exceeds the highest part of the starting siphon arranged therein, the inside of the starting siphon is filled with rainwater, and the draining operation is performed. To start.

When the starting siphon starts a draining operation, the water stored in the water storage container flows out at a stretch and flows down into a pipe-shaped member disposed thereunder. As described above, between the discharge destination and the high water channel resistance portion, the amount of outflow per unit time from here to the discharge destination is very small,
The water level in the pipe-like member will rise immediately. Thus, at the time when the outflow of the water in the water storage container is completed, the water level in the pipe-shaped member exceeds the highest part of the main siphon, and the inside of the main siphon is filled with the water flowing from the outflow end. Important conditions for discharging accumulated water in the space to be drained are achieved.

On the other hand, during this time, water is gradually drained from the high water channel resistance portion toward the discharge destination, and after the outflow of water from the starting siphon is completed, the water level in the pipe-shaped member is reduced. When the water level falls below the level of the accumulated water in the space to be drained, all the conditions for draining by the main siphon are adjusted, and the draining operation starts.

The drainage is performed in conjunction with a decrease in the water level in the pipe-shaped member, that is, at a drainage speed from the high water channel resistance portion. When the high water channel resistance portion is configured to always have a constant high water channel resistance, as described above, a slow draining operation is performed to drain water from the high water channel resistance portion. In a case where the waterway resistance is configured to be variable and the waterway resistance is reduced after the main siphon is filled with water, a quick drainage operation is performed.

As described above, according to the automatic drainage device of the present invention, if water accumulates in the space to be drained for some reason, rainwater or the like at the time of rain can be used to artificially generate water from the outside. The drainage can be performed without adding energy.

FIG. 4 is a partial sectional plan view showing another example, and FIG. 4 is a side view of FIG.

The automatic drainage device of this embodiment relates to an example in which the drainage device is installed in a burial chamber of a tomb. As shown in FIG. 1, a pipe-shaped member 2 is buried in an upright state adjacent to an ossuary room 1 of a tomb, and an outflow side of a main siphon 3 made of a smaller-diameter pipe material is placed inside the pipe-shaped member 2. And the inflow side is inserted and placed in the bone-filling chamber 1.

As shown in FIG. 1, the lower end of the pipe-shaped member 2 extends below the bottom of the bone filling chamber 1, and the lower end thereof communicates with a discharge destination 5 through a high water channel resistance portion 4. . The upper end of the pipe-shaped member 2 is
And extends slightly above the upper part of the container, and supports the water storage container 6.

The inflow end of the main siphon 3 is shown in FIG.
As shown in FIG.
a is formed and opened laterally through the filter 7 in the recess 1a. In addition, the main siphon 3 rises its inflow side from the recess 1a along the side wall 1b of the bone filling chamber 1, and passes the middle part outward from a cutout 1c formed at the upper end of the side wall 1b. Then, it was extended horizontally to the pipe-shaped member 2 as it was, and entered into the lateral hole 2a opened on the peripheral side thereof, and the outflow side from the portion of the lateral hole 2a was suspended to the high water channel resistance portion 4. Things.

The outflow end of the main siphon 3 is located further below a recess 1 a formed in the bottom of the bone filling chamber 1. The lid 1d of the bone filling room 1 has a side wall 1b.
A notch is formed corresponding to the notch 1c formed at the upper end of the main siphon 3 so as to easily pass through the corresponding portion of the main siphon 3.

As shown in FIG. 1, the high-water channel resistance portion 4 has a plug-shaped member 4a inserted at the lower end of the pipe-shaped member 2.
And a felt material 4b filled between the periphery thereof and the inner periphery of the lower end of the pipe-shaped member 2. Water that may flow down into the pipe-shaped member 2 is formed of the felt material 4b. Through the discharge destination 5 slowly.

In the case of this embodiment, the discharge destination 5 is a portion filled with gravel or gravel formed around the high water resistance portion 4. It has such a capacity that the total amount of accumulated water in the bone filling room 1 and the amount of water flowing down for starting the main siphon into the pipe-shaped member 2 can be discharged therein. Be configured. The water that has flowed out to the discharge destination 5 will eventually penetrate into the ground from around it.

As shown in FIG. 1, an auxiliary pipe 6a penetrating the inside and outside of the water storage container 6 is arranged in an upright state at the bottom center, and the lower part of the auxiliary pipe 6a is connected to the upper end of the pipe-shaped member 2. , So that it is supported by the upper end thereof. The auxiliary pipe 6
a, a notch is formed in a part of the upper end thereof, the middle of the starting siphon 8 is locked in the notch, the inflow end is located near the bottom of the water storage container 6, and the outflow end is positioned. Near the lower end of the auxiliary pipe 6a (below the bottom of the water storage container 6)
It is located in.

The upper part of the water storage container 6 is covered with a lid 6b. The lid 6b is provided with a large number of water-permeable holes 6c, 6c,... Which penetrate the front and back, so that rainwater can flow down into the water storage container 6b through these holes in the event of rain or the like. . In addition, the volume of the portion surrounded by the inner periphery and the bottom of the water storage container 6 and the outer periphery of the auxiliary pipe 6 is such that when the water accumulated therein flows down into the pipe-shaped member 2, the water level becomes the main siphon. It was possible to exceed the highest part of No. 3.

In the figure, GL is a ground line,
1e is a foundation of the bone filling room 1 and constitutes the bottom thereof. In addition, this bottom part is opened in the ground at the central part of the bone filling room 1.

Therefore, according to the automatic drainage device of this embodiment, if water accumulates in the bone filling room 1 for some reason, the water in rainy weather is used for startup, and this water is
The drainage can be surely performed without any particular labor.

As described above, the bone filling chamber 1 has its bottom open in the ground, and water flowing through the ground may enter through the opening for various reasons. If water is formed, it is hardly discharged through the opening. However, the accumulated water thus generated is surely discharged by the automatic drainage device of this embodiment as described below.

As described above, this automatic drainage device operates by using water supplied by natural phenomena such as rainwater for startup. As described above, the water storage container 6
Have many water-permeable holes 6c, 6c,... Opened in the lid 6b, and in the case of rainy weather, rainwater flows down into the water storage container 6 through these holes and is stored. When the level of the rainwater in the water reservoir 6 exceeds the highest part of the starting siphon 8, the starting siphon 8
Is filled with rainwater, which starts a draining operation.

When the starting siphon 8 starts the draining operation, the water stored in the water storage container 6 flows out at once, flows down into the pipe-shaped member 2 disposed thereunder, and the water level therein rises immediately. As described above, between the lower end of the pipe-shaped member 2 and the discharge destination 5, the high channel resistance portion 4 is formed, and the amount of outflow per unit time from this to the discharge destination 5 is extremely small. This is because

Thus, the water level in the pipe-shaped member 2 rises rapidly, and at the time when the outflow of the water in the water storage container 6 is completed, the water level in the pipe-shaped member 2 reaches the highest point of the main siphon 3. The main siphon 3
The inside is filled with water flowing from the inside of the pipe-shaped member 2 through the outflow end, and preparations for draining the accumulated water in the bone filling chamber 1 are made.

On the other hand, during this time, the drainage is gradually performed from the high water channel resistance portion 4 toward the discharge destination 5, and after the outflow of the stored water from the starting siphon 8 is completed,
The water level in the pipe-shaped member 2 gradually decreases, and when this water level falls below the level of the accumulated water in the bone filling room 1 at that time, the draining operation by the main siphon 3 starts.

The drainage is performed slowly as the water level in the pipe-shaped member 2 decreases. Since the drainage speed from the high channel resistance part 4 is very low, the water level in the pipe-shaped member 2 decreases very slowly, and accordingly, the water from the bone filling room 1 through the main siphon 3 is reduced. The drainage rate must be very slow. However, although the drainage speed is very low, all of the accumulated water will eventually be drained. In the case of this embodiment, the drainage target is the bone filling room 1, and it does not matter if the drainage takes a little time.

The water discharged from the high channel resistance part 4 to the discharge destination 5 gradually penetrates into the ground.

As described above, according to the automatic drainage device of this embodiment, if water accumulates in the bone filling room 1 for some reason, artificial water is used from outside using rainwater during rainy weather. The drainage can be reliably performed without adding energy to the water.

By the way, instead of the lid 6b, the water storage container 6 is provided with a turtle-shaped decorative lid 16b as shown in FIG.
Can be coated. The decorative lid 16b has a large number of water-permeable holes 16c, 16c,... Penetrating the front and back, through which rainwater and the like can be guided into the water storage container 6. A filter 17 is interposed midway between the water-permeable holes 16c, 16c,... To prevent external dust and the like from entering the water storage container 6 together with water.

Therefore, when the decorative lid 16b is employed, the water storage container 6 is covered with the lid 16b, and it is possible to harmonize with the surrounding scenery. Also, rainwater or the like can be introduced into the water storage container 6 through the water-permeable holes 16c of the decorative lid 16b, so that there is no problem in that respect. Furthermore, since the filter 17 is interposed in the middle of the water-permeable holes 16c, there is no danger of dust entering the water storage container 6, and as a result, dust is carried in just before the high water path resistance portion 4. Thus, there is no possibility of causing a problem of completely losing the water permeability.

Instead of the water storage container 6, as shown in FIG. 3 and FIG. 4, a rain water receiving container 26a for receiving water from the outside such as rain water, and a closed container 26c for receiving the supply of the water through a pipe 26b. Means can be configured. In this case, the upper part of the rainwater receiving container 26a is formed as a mesh lid 26d, so that rainwater can be easily introduced into the net lid 26d. Further, in the closed container 26c, a starting siphon is provided in the same manner as that provided in the water storage container 6, and when the water level in the closed container 26c rises up to exceed the highest part of the starting siphon, The water therein is rapidly drained and this flows down into the pipe-shaped member 2. As shown in FIGS. 3 and 4, the water flowing down from the starting siphon is introduced into the pipe-shaped member 2 from above through piping 26e.

Therefore, in the case where the above-described configuration is employed instead of the water storage container 6, by extending the pipe 26b, the rainwater receiving container 26a can be disposed at any position. Therefore, when the bone filling room 1 is in a positional relationship where it is difficult to obtain rainwater or the like, or when it is not preferable that the water storage container 6 is exposed to the vicinity as described above, it is difficult to obtain the rainwater or the like. The rainwater receiving container 26a is disposed in a place where the rainwater is easily received or where there is no problem in appearance even if it is installed, and the rainwater or the like is received therewith. The inevitable closed container 26c
Can be led to.

[0056]

Therefore, according to the automatic drainage device of the present invention, if water accumulates in the drainage target space for some reason, water due to natural phenomena such as rainy weather is used for startup. Although it may take some time before drainage, it can be drained without any manpower.

According to the automatic drainage device of the second aspect of the present invention, the water storage container exposed to the outside is covered with a cosmetic covering material so as to be consistent with the external scenery surrounding the drainage target space to be applied. You can do it.

According to the automatic drainage device of the third aspect of the present invention, it is not preferable that the facilities surrounding the space to be drained have a positional relationship in which it is difficult to obtain rainwater or the like, or that the water storage container is exposed in the vicinity. In such a case, the rainwater receiving container is arranged in a place where rainwater or the like is easily obtained or a place where there is no problem in appearance even if it is installed, and the rainwater or the like is received by this, and the water is drained. It can be guided to the closed container which must be arranged close to the target space. Therefore, the problem of landscape and the problem of obtaining rainwater can be easily solved.

According to the automatic drainage device of the fourth aspect of the present invention, it is possible to obviate the possibility that dust or the like accumulates immediately before the high channel resistance portion and clogging occurs.
