Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rainwater basin with a filtering device.

[0002]

2. Description of the Related Art Generally, rainwater is often used by storing rainwater that has fallen on the roof of a building in a rainwater tank through a downspout (rain gutter). There are many methods to remove only a fixed amount of rainwater that has started to flow from the downspout, for the purpose of removing (such as leaves and leaves).

As an example of the method, there is a container for storing a certain amount of initial rainwater to be removed, and a float operating at the water level is provided inside the container. The upper part of the container provided with this float Is connected to a downspout through a connecting material provided with a strainer and a branch port, and rainwater from the roof flows into the downspout, after which coarse dust is removed by the strainer and flows into the container in which the float is placed, The float gradually rises according to the inflow amount, and when it reaches a certain amount, it blocks the inflow into the container and switches the flow path from the branch port provided in the connecting material to the storage tank. .

[0004]

By the way, the dust on the roof is dust, dust, leaves, etc., as well as feces of pigeons, sparrows, crows, etc., when they are carried or relayed for feeding or nesting. There is a wide variety of food scraps and containers such as plastic bags, styrene pieces, paper scraps, vinyl strings, wires, and twigs, and some of these may have masses that do not easily flow even with a little rain. To be

Also, bird droppings are present in a state of being burned on the roofing material under hot weather, and it is unlikely that the droppings will easily flow in a short time even if it rains. This is bird droppings attached to the roof of a car or the hood. However, it is a common experience, and it can be assumed that the shape and amount of the various dust particles scattered, not to mention leaves, during normal wind, rainstorms, and typhoons are higher than usual.

[0006] As described above, and the way rain is falling (the size of raindrops, the amount of rainfall per hour, etc.) and the condition of the roof (area, slope, etc.) are unspecified, so that dirt can be removed or dust can be removed. It is impossible to specify the amount of initial rainwater to be removed because it is impossible to predict the time and amount of rain to collect the species in the rain gutter.In addition, in the conventional technology, relatively large leaves such as leaves are filtered by a strainer. However, because of the strainer's shape and location, a large filtration area cannot be taken, and it is highly likely that the strainer will immediately become blocked.

Therefore, according to the present invention, the initial rainwater can be removed, and the filtration can be performed at all times without being affected by the type and shape of dust and the conditions during rainfall, and the load on the filtration device in the next step can be reduced. It is intended to provide a rainwater basin with a filtering device.

[0008]

In order to solve the above problems, the present invention provides a rainwater basin with a piping unit, one of which is connected to a downspout, and a removable filter bag.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below.
Detailed description will be given based on the drawings.

FIG. 1 is a plan view of a rainwater basin with a filtering device, and FIG.
Is a front view with a part in section, FIG. 3 is a plan view of the piping unit, FIG. 4 is the same front view, and FIG. 5 is a side view thereof. In these drawings, reference numeral 1 is a rainwater pit and reference numeral 2 is piping. unit,
Reference numerals 3, 4 and 5 are pipe connecting members, reference numeral 6 is a connecting member to the filter bag, reference numerals 7 and 8 are filtering bags, and rainwater is supplied from one connection port 10 of the pipe connecting member 3 connected to the downspout. The connection port 13 of the pipe connection member 5 that has flowed in and is provided in the rainwater basin 1.
More outflow.

In one embodiment according to the present invention, the pipe connecting member is widely marketed, and the pipe connecting member 3 is commonly called 90 ° Y and has three connecting ports, and other pipes. The connecting members 4 and 5 are commonly called 90 ° elbows and have two connecting ports, which are joined together through piping materials. The piping unit 2 combines the piping connecting members 3 and 4, The connection port 10 to the down gutter and the connection ports 11 and 12 in the opposite direction are formed in a positional relationship with a height difference h. The connection port 10 is connected to the down gutter so that one of the rainwater basins 1 can be connected. The side plate is passed through and fixed, and the connection port 13 of the pipe connection member 5 is a connection port for the rainwater utilization process, and the other opening is fixed to the bottom of the rainwater basin 1. This fixed position is a side surface. However, if rainwater remains in the rainwater basin 1 after the rain is over, it will rot. Since it may occur, it is desirable to fix it in a position where it will not remain.

Next, the filter bags 7 and 8 can be easily manufactured by sewing a commercially available filter cloth, so a detailed description thereof will be omitted. However, the connecting members 6 provided on the pipe connecting members 3 and 4 connect the connecting ports 11 and 8. The connection member 6 to be mounted and fixed on the connection member 12 is generally of various types such as a commercially available fastening member, a screw type, an insertion lock type, etc., so a detailed description thereof will be omitted. Is preferred.

With this structure, the rainwater flowing in from the connection port 10 through the downspout is first filtered by the filter bag 7 and sent from the connection port 13 to the next step. The filter bag 7 is the strainer described above. On the other hand, it has a surface area that is incomparable, and the possibility of clogging is extremely low, but even if it is occluded, it is arranged with a height difference h so that it will flow into the upper filtration bag 8, It is extremely unlikely that all the flow paths will be blocked even when there are many trees or during a typhoon.
By arranging 8 in two stages, it is possible to take measures to reduce the load on the advanced filtration device when the purpose of using rainwater requires advanced filtration.

The means is to make the mesh of the filter cloth of the filter bag 7 (lower side) as small as possible and also to remove extremely small dust. Of course, the smaller the mesh of the filter cloth is, the more the clogging phenomenon occurs. It is more likely to occur, but it takes a considerable amount of time and amount of water to be clogged due to the large filtration area, and it is considered to be pure rainwater when the flow path moves to the filtration bag 8 (upper stage). This means that in rainwater use that requires advanced filtration, it can be used to significantly reduce the load on the filtration device.

For example, at a certain technical university, rainwater is equipped with a rainwater storage tank of 100 tons or more for membrane filtration in order to be used not only for general water sprinkling and for toilets but also for experiments. However, the load on the filtration membrane in such a case can be reduced.

Although the present invention is configured as described above, the present invention is not limited to the above-described embodiments, and appropriate design changes, improvements, and applications may be made without departing from the scope of the present invention. The rainwater basin 1 is not limited to a square and may be circular, and the pipe connection members 3, 4, 5 and the like may be manufactured not limited to commercially available products, and the shape is not limited to a round shape and may be a rectangular shape. The combination of members is also not limited.

[0017]

According to the present invention, the piping unit 2 and the filtration bags 7 and 8 are arranged in the rainwater basin 1 and have a wide filtration area, so that the present invention is applicable not only to the initial stage but also to storms, typhoons and the like. It is possible to filter at all times, and by arranging the constituent members in the rainwater basin 1, there is no need to install obstacles on the walls of the building or on the ground.

Further, the piping unit 2 includes a piping connection member 3
4 is combined with each other and the height difference h is provided between the openings 11 and 12, so that a complicated flow path switching means is not required and two piping units are formed with the minimum number of members. By attaching and fixing the filter bags 7 and 8 to the, it has a large filtering ability.

As described above, the present invention can be manufactured at a very low cost because the number of constituent members is extremely small, mass-produced commercial products can be used, and the structure is also very simple. Since it can be washed and repeatedly used, there is no running cost. Even though it has such a simple structure, it is not limited to the initial filtration of rainwater, but it has the ability to support constant filtration and advanced filtration in the next step.
