Abstract

PURPOSE:To provide an irrigation apparatus for applying rainwater to plants and exhausting excess rainwater to a drain pipe by attaching an intake apparatus in the middle of a downspout, extending a water-spraying pipe from the intake apparatus to the plants and connecting an overflow pipe to the intake apparatus. CONSTITUTION:Rainwater flowing down from an eaves gutter through an upper side downspout 2a is received with a receiving pipe 5 of an intake apparatus 4 and applied to plants from a water-spraying hole 7a of a water-spraying pipe 7. In the case of a heavy rain, the water overflowed from the receiving pipe is guided through an overflow pipe 6 to a downstream side downspout 2b and discharged to a drain pipe 3. The water-spraying pipe is supported with a supporting post 9 to cover the plants under the eaves.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for extracting rainwater from a rain gutter to irrigate a planting under an eaves.

[0002]

2. Description of the Related Art Ground-planted plants can usually be grown only by rain and need not be watered. On the other hand, eaves,
Since planting under eaves, bay windows, etc. is not exposed to rain, it must be watered occasionally. However, watering is easy to forget, and people often forget to water and die under the eaves.

Conventionally, there has been an automatic irrigation system in which a water supply valve is opened by a timer to supply tap water to plants at a fixed time every day, but the system is complicated and many failures occur.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to automatically irrigate plants that are not directly exposed to rain with rainwater.

[0005]

[Means for Solving the Problems] An intake device is provided in the middle of a vertical gutter. The water intake device is composed of a receiving pipe that receives rainwater from the upstream downpipe and an overflow pipe that guides the water overflowing from the receiving pipe to the downstream downpipe when it rains heavily. Guide the sprinkler pipe from the bottom of the sagger to the planting.

[0006]

[Operation] When it rains, the rain that has fallen on the roof travels down the gutter and accumulates in the receiving cylinder. The accumulated water is poured from the sprinkling pipe into the planting. When the rain is heavy, rainwater begins to overflow from the stub, and the overflowing water flows through the overflow pipe into the downpipe.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In FIGS. 1 and 2, reference numeral 1 is an eaves trough attached to the eaves of a building, and reference numeral 2 is downward from the eaves trough along the outer wall of the building. An extending vertical gutter, reference numeral 3, is an underground drainage pipe to which the vertical gutter is connected.

A water intake device 4 is attached in the middle of the vertical gutter 2. As shown in FIG. 3, the water intake device 4 includes a receiving cylinder 5 and an overflow pipe 6. The receiving cylinder 5 is provided directly below the upstream vertical gutter 2a so as to be continuous therewith. The overflow pipe 6 branches laterally from the upper part of the receiving cylinder 5, then bends and extends downward, and the tip of the overflow pipe 6 bends again and is connected to the downstream side trough 2b. As shown by the chain line in FIG. 3, when the drainage pipe 3 can be provided directly below the overflow pipe 6, the number of bends can be small.

The sprinkling pipe 7 is guided horizontally from the bottom of the receiving cylinder 5. The sprinkling pipe can be guided not only in one direction but also in two directions as shown in FIG. The sprinkling pipe 7 is piped so as to cover the planting 8 under the eaves, and is supported by the columns 9. If the sprinkling pipe 7 is made of plastic bamboo together with the pillars 9, it will be a bamboo fence and will look good.

The water spray pipe is provided with water spray holes 7a at regular intervals. A cap (not shown) is attached to the tip of the sprinkling pipe so that it can be easily cleaned when the sprinkling hole is clogged.

In this irrigation system, when it rains, the rain on the roof gathers in the eaves gutter 1 and then flows to the vertical gutter 2a.
Further, it flows into the receiving cylinder 5 of the water intake device 4. The water that has entered the receiving pipe passes through the water sprinkling pipe 7, draws an arc from the water sprinkling hole 7a, and pours onto the planting 8.

When the amount of water flowing down the upstream downflow gutter 2a increases due to heavy rain, the water level in the receiving cylinder 5 rises, and eventually the overflow pipe 6 overflows, and the overflowing water flows downstream. It flows into the vertical gutter 2b and flows out through the drainage pipe 3.

FIG. 4 shows a water intake device 1 with a better appearance.
4 is an example. The overflow pipe 16 has a large diameter, and the receiving cylinder 1 is placed therein.
5, and a drain hole 17 is formed in the upper pipe wall of the receiving cylinder 15.
In the light rain, rainwater enters the receiving cylinder 15 from the upstream side gutter 2a and is sprayed from the water spray pipe. When it rains heavily, the water overflowing from the receiving pipe 15 passes through the drain hole 17, passes between the overflow pipe 16 and the receiving pipe 15, and flows out into the downstream side trough 2b.

[0014]

According to the irrigation system of claim 1, the water intake system is provided in the middle of the vertical gutter, and the sprinkler pipe is led from this water intake system to planting. Planting under eaves can be protected from water shortage. When the amount of rain is low, the entire rainwater that flows down the vertical gutter is used for irrigation, and when the rain becomes strong, the rest of the irrigation water is drained to the drainage pipe, so irrigation can be performed properly.

The apparatus according to the second aspect of the present invention has an overflow pipe branched from a receiving cylinder extending below the upstream side gutter, and has a simple structure and can be manufactured at low cost. In the irrigation system according to the third aspect, since the receiving pipe is housed in the overflow pipe, it has a good appearance and does not spoil the scenery.
