Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a rainwater storage device for collecting and utilizing rainwater.

(Prior Art) Conventionally, in mountain huts, remote islands, and other areas without water supply facilities, rainwater, snow, and other rainwater have been collected and stored for use. The purpose of using these rain waters is drinking water, and the rain water is used after it has passed through a filter tank.

(Problems to be solved by the invention) However, the above-mentioned rainwater utilization facilities have the following problems.

Because rainwater is used to obtain drinking water, large-capacity tanks cannot be installed because if the collected rainwater rots, it becomes unfit for drinking. Therefore, for example, even if you want to use rainwater for watering plants, flushing toilets, etc. in order to save water in a land with a water supply system, there is a problem that conventional rainwater utilization facilities are too small to cope with the problem. Yes, the solution is an issue.

Therefore, an object of the present invention is to provide a rain water storage device that allows rain water to be used for purposes other than drinking at home.

(Means for Solving the Problems) In order to solve the above problems, the present invention has the following configuration.

That is, it can be buried underground, and when buried, part or all of the top surface opens to the ground surface, a lid is detachably attached to the opening, and collected rain water is introduced. A removal tank is connected to a water pipe and has an outlet in the middle of the wall in order to temporarily store the introduced rainwater. It is connected to a plurality of filter plates for causing the flow to meander in the vertical direction to precipitate dirt, and is connected to the above-mentioned removal tank for inflow and storage of rain water, and a mud pool is provided on a part of the bottom surface, which is one level lower than the other bottom surface. a water distribution tank, a drain pipe connected to the water distribution tank and formed such that the tip of the water distribution tank faces downward, and for guiding water to a drainage channel etc. when the water exceeds a certain amount; The tank is characterized by being provided with a water distribution pipe for sending water in the water distribution tank to a destination outside the water distribution tank, and a pump connected to the water distribution pipe.

(effect) The operation will be explained with reference to the drawings.

The collected rain water passes through the water conduit 18 and enters the removal tank 10, where the flow is meandered vertically by the filter plates 20a and 20b, so that the dust 46 is removed.
etc. are removed by precipitation. The water once accumulates in the removal tank 10 and then passes through the outlet 22 to the water distribution tank 24.
It accumulates in Water in the water distribution tank 24 is pressurized by a pump 34 and sent to a destination through a water distribution pipe 36.

Furthermore, the drain pipe 32 prevents the water level in the water distribution tank 24 from exceeding a certain level. The mud in the water distribution tank 24 accumulates in a mud basin 28. Further, since the tip of the drain pipe 32 is directed downward, when the drain pipe 32 is below the water surface 52, odor can be prevented from escaping outside the tank. When cleaning, both the removal tank 10 and the water distribution tank 24 can be cleaned through the openings 14 and 26.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the configuration will be explained.

In FIG. 1, reference numeral 10 denotes a removal tank, which is buried underground and has an open top surface that opens into the ground surface 12 as a manhole 14. An inlet 16 is opened in the wall of the removal tank 10, and a water conduit 18 is passed therethrough. This water pipe 18 is connected to a rain gutter (not shown) provided around the roof (not shown), and the rain and snow collected by the gutter are guided to the removal tank 10. . The tip of the water conduit 18 is bent downward. A plurality of filter plates 20a, 20b made of plastic or metal plates are arranged at the bottom of the removal tank 10, and both end surfaces of the filter plates 20a, 20b are connected to the removal tank 1.
Connected to the 0 wall. Figure 2 shows the removal tank 10.
shows a front view. As shown in FIG. 2, the lower surface of the filter plate 20a is connected to the inner bottom surface of the removal tank 10, the lower surface of the filter plate 20b is separated from the inner bottom surface of the removal tank 10, and the upper surface of the filter plate 20b is connected to the inner bottom surface of the removal tank 10. It is located at a higher position than the top surface of the plate 20a.

Therefore, as shown in FIG. 2, the water that has entered the removal tank 10 through the water conduit 18 meanders in the vertical direction as indicated by arrow A.

Note that 22 is an outlet through which water in the removal tank 10 flows out from the removal tank 10 to a water distribution tank to be described later.

The explanation will be given again with reference to FIG. A water distribution tank 24 has a larger capacity than the removal tank 10, is formed integrally with the removal tank 10, and is also buried underground. The water distribution tank 24 is connected to the removal tank 10 via an outlet 22. A part of the upper surface of the water distribution tank 24 also opens to the ground surface 12, and also serves as a manhole 26. 1 on the inner bottom of the water distribution tank 24
A mud puddle 28 formed in a low step is provided.
Further, a drain port 30 is opened in the wall surface, and a drain pipe 32 is passed through it. The drain pipe 32 is connected to a drain channel (not shown). In addition, the drain pipe 32
The end portion inside the water distribution tank 24 is also formed to be bent downward.

34 is a pump, and the submersible pump is a mud puddle 28
is installed inside. The pump 34 has a water pipe 36 for sending the water in the water tank 24 to the destination.
is connected. The water pipe 36 is the water tank 24
A faucet 40 is attached to reach the ground through an outlet 38 bored in the top surface.

Note that the manholes 14 and 26 are provided with covers 42 and 44 to prevent dirt and the like from entering.

Next, the function of this rainwater storage device will be explained with reference to FIGS. 1 and 2.

Rainwater collected by a gutter (not shown) is sent to the water conduit 18
It passes through and enters the removal tank 10, where it is temporarily stored. The flowing water passes through filter plates 20a and 20 as shown in FIG.
Due to the difference in the height position of b, it meanders in the vertical direction as shown by arrow A, and during this time, the dust 46 and the like accumulates at the bottom of the removal tank 10. The water from which the dust 46 has been removed enters the water distribution tank 24 from the outlet 22 and is stored therein. When using the water in the water distribution tank 24, when the pump 34 is driven, pressurized water is supplied into the water distribution pipe 36, and the water rises through the water distribution pipe 36 to the faucet 40. Therefore, by attaching a hose (not shown) to the faucet 40, water can be sent to the destination via the hose.

It is conceivable that the water level in the water distribution tank 24 rises during periods of heavy precipitation. Even at this time, the water level in the water distribution tank 24 does not rise above the position of the drain pipe 32 because the drain pipe 32 connected to a drainage channel (not shown) is arranged on the wall surface of the water distribution tank 24. Water in an amount exceeding the location of the drain pipe 32 is drained to the drainage channel via the drain pipe 32. Therefore, the water level in the water distribution tank 24 never exceeds a certain level. In addition, due to long-term use, mud and dirt 48 can also be found inside the water distribution tank 24.
This accumulates in the mud puddle 28. Therefore,
Cleaning becomes easier when cleaning the water distribution tank 24 as well. When cleaning the removal tank 10, for example, take out the pump 34 from the manhole 26 and clean the removal tank 10.
The manhole 14 may be opened and the pump 34 may be used to suck out the dirt 46 and the like in the removal tank 10 together with the water. At that time, the filter plates 20a, 20
It is convenient for cleaning if b is made removable.

If not used for a long period of time, the water in the removal tank 10 and the water distribution tank 24 may rot and produce an odor.
Since the tips of the water conduit pipe 18 and the drain pipe 32 are bent downward, the ends of both pipes 18 and 32 are at the water surface 50,
If the temperature is below 52, it is possible to prevent odor from coming out of the tank.

Various preferred embodiments of the present invention have been described above, but the present invention is not limited to the above-mentioned embodiments. For example, two or more removal tanks may be provided, and the The outlet can be installed on the wall of the water tank, the pump can be installed outside the tank, and the end of the water pipe can be connected to various devices, so it can be used for water sprinklers, flush toilets, etc. It goes without saying that many modifications can be made without departing from the spirit of the invention, such as for various uses such as fire prevention.

(Effects of the invention) By using the rain water storage device according to the invention, it becomes possible to realize a relatively large rain water storage means for household use other than drinking. A removal tank is provided,
Furthermore, a mud basin is provided in the water distribution tank, and openings are provided in both tanks to make cleaning easier.
Also, since a pump is installed, the water distribution amount and water distribution distance can be increased, allowing for a variety of uses. Further, by providing a drain pipe, it is possible to maintain a constant water level in the water distribution tank. Further, by oriented the tips of the water conduit pipe and the drain pipe downward, it is possible to prevent odor from escaping within the tank while the tips are below the water surface.
