The rainwater collecting means 10 forms a supporting jaw 12 around the rainwater collecting tank 11, and forms the rainwater collecting body 13 in a hat-shaped shape and also forms a plurality of through holes 14. And, by forming a support piece 15 around the lower part, and supporting the support piece 15 to the support jaw 12 and coupled as a fastening element such as a bolt, a plurality of bars, the rainwater collector body ( 13) is shaped like a hat shade to improve the collection efficiency when it is raining with the wind, and when the wind is blowing, for example, dust, fallen leaves, wrapping paper is separated by slipping to prevent the blockage of the through hole (14). .

In addition to the above, the rainwater collecting means 12 may be formed of only the rainwater collecting tank 11 in a funnel type (see KR 10-2013-0112164 A and the like).

The foreign matter separation tank 20 is made of metal such as stainless steel, or reinforced thermosetting plastic (Sheet Molding Compound, SMC, impregnated and reinforced with glass fibers in a compound mixed with a filler, a catalyst, a release agent, and the like) It is made of a cross-section cylindrical or quadrangular, such as to the rainwater collecting means 10 is connected to the rainwater induction pipe 21.

When the rainwater induction pipe 21 is connected to the foreign matter separation tank 20, the discharge portion 22 is disposed close to the one side wall of the central portion of the foreign matter separation tank 20, the rainwater containing foreign matter is foreign matter separation tank By discharging to the wall side of (20) to allow the foreign matter to sink along the wall, the separation of the foreign matter is improved.

And when connecting the discharge portion 22 of the rain water induction pipe 21 toward the side wall of the foreign matter separation tank 20, the U-shaped similar shape (including the U-shaped rotated 90 °) to lower the discharge pressure By increasing the separation effect.

The automatic float valve 30 fixes the valve body 31 to the bottom of the foreign matter separation tank 20, forms a valve seat 32 on the valve body 31, and on the valve body 31 In addition to installing the support cylinder 33, the discharge grooves 34 are formed on both sides of the lower portion of the support cylinder 32. In addition, the valve 36 is formed in a rod shape, and a lower end thereof is formed into a taper having a shape in close contact with the valve seat 32 to be inserted into the support cylinder 33 while being lifted.

In addition, by supporting the center of the lever 37 with the pins 38 on both sidewalls of the foreign matter separation tank 20 or by installing a support on the bottom, the lever 37 is supported for the seesaw movement, and the lever 37 One side of the) supports the float 39 with a pin, the other side is connected to the rod 40 connected to the valve 36, when the float 39 is raised, the other side of the lever 37 is lowered to the valve As the 36 is guided to the support cylinder 33 and descends to be in close contact with the valve seat 32, the automatic float valve 30 is closed. When the float 39 is lowered, the other side of the lever 37 is raised to raise the valve. 36 is guided to the support cylinder 33 and raised to open the automatic float valve 30.

In addition, the valve 36 of the automatic float valve 30 has a discharge groove 34 formed in the support cylinder 33 installed in the valve body 31 when the valve 36 is in close contact with the valve seat 32. By forming a rainwater discharge path 41 exposed to the), when the automatic float valve 30 is closed to discharge a small amount of rainwater containing foreign matter collected in the bottom of the foreign matter separation tank 20.

As described above, when a small amount of rainwater including a foreign matter is discharged through the rainwater discharge passage 41, when the rain does not rain, the rainwater including the foreign matter is discharged and the float 39 descends as the surface of the foreign matter separation tank 20 descends. As the other side of the 37 is raised and the valve 36 is raised to open the valve 36 of the automatic float valve 30, all the rainwater in the foreign matter separation tank 20 is discharged to the outside to maintain the empty space state. .

The rainwater discharge passage 41 is installed to lower the float 39 to open the valve 36 of the automatic float valve 30 with no power or no power supply, but when the system of the present invention is operated, that is, the foreign matter separation tank Even when the clean rainwater from which the foreign matter is separated from the 20 is discharged to the reservoir 50 side, a small amount of the rainwater in the foreign matter separating tank 20 is discharged to the outside.

As described above, the system of the present invention forms a small cross-sectional area of the rainwater discharge path 41 in order to overcome the low rainwater collection efficiency because the rainwater is discharged to the outside during operation, but the rainwater collection efficiency is low. Likewise, even if the cross-sectional area of the rainwater discharge path 41 is made small, if only a decrease in the water surface for the lowering of the float 39 occurs, the function is sufficiently achieved.

In addition, the bottom of the reservoir 50 to be described later is formed to be inclined downward toward the valve body 31 so that the foreign matter is easily discharged when the rainwater containing foreign matter discharged to the outside.

When rainwater containing foreign matters is introduced into the foreign matter separation tank 20 as described above, the automatic float valve 30 is opened until the water level becomes full, so that the initial rainwater is drained, but the position of the float 39 is In other words, when the water level is high, the valve 36 is in close contact with the valve seat 32 and the automatic float valve 30 is closed, so that the clean rain water from which foreign matters are separated is stored in the water storage tank 10. Since the rainwater discharge passages 41 and 141 formed in the 36 or the valve seat 32 remain open, a small amount (small amount) of rainwater in the rainwater reservoir 20 is discharged to the outside, but the discharge amount thereof is discharged to the outside. Is significantly less than the amount of rain that normally falls, thus not affecting rainwater collection efficiency.

When the rainwater falling down as described above is supplied from the foreign matter reservoir 20 to store the clean rainwater from which the foreign matter is separated in the storage tank and continues to use for necessary purposes, the rain stops when the rainwater flows into the foreign matter separation tank 20, the foreign matter Rainwater stored in the separation tank 20 is discharged to the outside through the rainwater discharge path 41, 141 as the water level is lowered as the float 39 is lowered of the lever 37 As the opposite side of the float 39 rises, the valve 36 falls from the valve seat 32, and the automatic float valve 30 is opened, and the rainwater in the foreign matter separation tank 20 is discharged to the outside at once, and the foreign matter separation tank 20 is provided. I am in a state without rain at all.

When the empty space without rain water in the foreign matter separation tank 20 as described above is to clean the interior or repair the automatic float valve 30.

When there is no rain water in the foreign matter separation tank 20 as described above, the automatic float valve 30 is kept in an open state, the rain is collected in the rain water collecting means (10), 100 in the above state When the rainwater containing foreign matters flows into the foreign matter separating tank 20, when the water level rises and the water level rises, the valve 36 closes the valve seat 32 and repeats the above-described foreign matter separation and water storage.

The present invention separates the foreign matter contained in the rainwater and stores it in a water tank and uses it for necessary uses, and thus it is possible to continue using rainwater having good foreign matter separation and clean rain water as compared to removing conventional rainwater only, and also containing a small amount of rainwater containing foreign matter. Since the bay is disposed of, the rainwater collection efficiency is good.

In addition, the automatic float valve can be installed regardless of the installation place because it operates without power, power.
