Abstract

A rainwater extraction device having a simple structure and being difficult to catch dust is obtained.
An insole 5 is provided so that rainwater can be stored in a cylindrical body 2 that is cut in the middle of a vertical rod 1. The insole has a shape that gradually narrows downward (conical shape), and a circular hole 6 is formed at the center thereof. In order to open and close this hole, the valve body 7 is provided on the lower side of the insole. The valve body is a sphere and is suspended by a coil spring 11 from a pin 10 passed to the upper part of the cylinder, and is usually pulled up by the force of the spring to close the hole 6.

Description

  The present invention relates to an apparatus for taking out rainwater flowing in a vertical fence and using it for watering plants.

  Conventionally, various rainwater extraction devices are known, and a typical one is one in which a rainwater drain is inserted into a vertical gutter and rainwater is taken out of the vertical gutter (for example, patent publication). 2002-167922). Such a structure has a simple structure, but has a drawback that dust such as leaves flowing in with rainwater is easily caught.

  An object of the present invention is to obtain a rainwater extraction device that has a simple structure and is difficult to catch dust.

  The rainwater take-out device of the present invention is provided with an insole having a hole at the center in a cylindrical body attached in the middle of a vertical shaft. Furthermore, a valve body that moves up and down under the insole to open and close the hole, an elastic member that urges the valve body upward, and a discharge port that discharges rainwater accumulated in the cylindrical body are provided. .

  In this device, the hole in the bottom of the bottom is normally closed with a valve body.When rain starts, rainwater accumulates in the cylinder, and when the liquid level gradually rises to the level of the discharge port, Rainwater begins to flow out. When rain becomes stronger and the flow rate of rainwater flowing into the cylinder exceeds the flow rate coming out of the discharge port, the liquid level rises, and when it reaches a certain level, the valve body is energized by the water pressure applied to the valve body. The elastic body is stretched, the valve is opened, and a part of the rainwater that flows in from the upper part flows through the hole to the lower vertical shaft, and the liquid level does not rise any more.

  Garbage such as leaves flows into the cylinder along with rainwater, but when the valve opens, the garbage is discharged down through the hole. In this apparatus, since the dust is discharged directly below, it is not caught on the way. In particular, in this case, the insole has a mortar shape (Claim 2), so that dust is not caught on the insole and is smoothly discharged.

  If the elastic member is constituted by a tension coil spring and the upper end of the spring is supported by a pin extending between the walls of the cylindrical body (Claim 3), the structure is simple and the operation is reliable.

  This rainwater take-out device is incorporated in the cylindrical body 2, and is cut out in the middle of the vertical gutter 1 and then used by inserting the cylindrical body 2. The cylinder 2 is made of plastic, has a length of about 250 mm, and an outer diameter of 60 mm, similar to a vertical gutter. Both end portions of the cylindrical body are formed to be thin and can be inserted into a vertical gutter. Further, circumferential grooves are cut at both ends, and an O-ring 3 is fitted therein to seal between the vertical rod and the cylinder.

  An insole 5 is provided so that rainwater can be stored in the cylinder 2. The insole has a mortar shape that gradually narrows downward, with a circular hole 6 in the center (lowermost part). In order to open and close this hole, the valve body 7 is provided on the lower side of the insole. The valve body is a plastic hollow sphere having a diameter larger than that of the hole 6 (the lower side of the sphere may be cut out as shown in FIG. 1), and a coil spring from a pin 10 passed to the upper part of the cylinder 2 The valve body 7 is usually pulled up by the force of a spring to close the hole 6. The coil spring is preferably made of stainless steel so as not to rust. The strength of the coil spring is adjusted by the length of the string 12. If a chain is used instead of the string 12, the length can be easily adjusted.

  Reference numeral 13 denotes a rainwater discharge port, which is provided at a position slightly higher than the valve. A hose connector 14 is provided on the side of the cylinder so as to be continuous with the discharge port 13.

  As for the operation of this device, when it starts to rain, the rainwater that has fallen on the roof flows from the eaves through the vertical rod 1 into the cylinder 2. Since the hole 6 in the inner bottom 5 is closed by the valve body 7, rainwater accumulates in the cylinder, and the liquid level gradually rises. As shown by the solid line in FIG. 1, when the liquid level reaches the discharge port 13, rainwater flows out from the hose 15 connected to the connector 14. During light rain, the liquid level hardly fluctuates, and rainwater flows out from the hose in this way. When the rain becomes stronger, the liquid level rises and the flow rate flowing out from the discharge port 13 also increases. When the rain leg becomes strong and the liquid level rises to a level indicated by a chain line, the coil spring 11 is extended by the water pressure applied to the valve body 7, and the valve 7 opens as indicated by the chain line, and the rainwater flowing in from above is shown. The part flows through the hole 6 to the lower vertical gutter 1 and the liquid level does not rise any further.

  Garbage, such as leaves, flows into the cylinder along with rainwater, but when the valve is opened, the garbage is discharged down through the hole 6. In particular, in this case, the insole has a mortar shape so that dust is not caught on the insole and is smoothly discharged.

  When the rain stops, the liquid level goes down to just below the discharge port 13, but there is no water outlet after that, so there is a risk that rainwater will remain and the valve will freeze in the winter. In order to prevent this, it is preferable to provide a small notch 6a around the hole 6 as shown in FIG. 2 so that the remaining water flows down from the notch even when the valve is closed.

  In this device, rainwater flows out from the discharge port while it continues to rain, so that it can be stored in a water bottle or the like and used for watering or watering plants. In particular, if it is installed in a place where there is no water supply, such as the 2nd floor veranda of a house, it can be used conveniently for watering plants.
