Description

Description: TECHNICAL FIELD The present invention relates to a rainwater utilization apparatus for storing rainwater in rainy weather and using the rainwater stored in fine weather for water utilization facilities such as a planting garden. .

(Prior art) Conventionally, for water supply and watering to facilities that use water such as fountains, ponds, artificial babbles, planting orchards, etc., it is common to use tap water directly by an automatic water supply device. It is.

(Problems to be Solved by the Invention) However, when tap water is used, running costs are increased, and in places where tap water is difficult to secure, installation of water use facilities must be difficult or small. In many cases, tap water supplied to ponds and planting gardens is discharged as it is, and there is room for reconsideration in terms of securing water resources and effectively using water.

An object of the present invention is to reduce the running cost in a water use facility from the viewpoint of water supply cost, and another object is to install a water use facility of a necessary scale even in a place where tap water is difficult to secure and in an area. Another object is to make efficient use of water resources.

(Means for Solving the Problems) The present invention relates to water collecting units 1 and 11 provided in the ground below a watering facility 3 such as a planting garden, and water from the water collecting units 7a and 7b. 7
b, a water supply facility 4 such as a hydrophilic facility, and a water supply driving means 5a for water storage of the storage tank and a watering device 5b provided in the watering facility are connected by a water supply pipe 5c. A sprinkling section 5 and a rain detector 6 electrically connected to the water supply driving means and installed in the sprinkling facility.

The water collecting part may be constituted by the water collecting pipe 1 having a large number of holes 1a, or may be formed as a water collecting groove 11 formed on the upper surface of the water impermeable part when there is an impermeable part 13 in the ground. .

From the viewpoint of collecting rainwater that overflows from the water use facility 4 in rainy weather and reusing it, pipe the overflow flow pipe 4a to the water use facility 4 and guide the overflow pipe to the storage tank. I want.

(Action) Rainwater that has penetrated into the ground is collected by the water collection pipes 1 and 11, on the one hand, through the storage tank 2 and by the watering unit 5 for watering to the watering facility 3, and on the other hand directly to the water utilization facility 4. Can be used for makeup water.

Since the water collecting section 1 is disposed under the watering facility 3 in the ground, rainwater collected from the watering facility 3 can be watered again to the watering facility.

Rainwater that overflows from the water use facility 4 can be collected in the storage tank 2 by the overflow 4a.

(Example) First, a first example will be described with reference to FIG.

The rainwater utilization device of the present invention includes a water collecting unit 1, a storage tank 2, a water spray facility 3, a water utilization facility 4, a water spray unit 5, and a rain detector 6.

The water collecting section 1 is composed of a water collecting pipe, and the water collecting pipe is horizontally arranged under the ground, or a slope is provided so that the outlet side is lowered so that rainwater can be easily collected (in the example shown in the horizontal state). In addition, piping is provided directly below the planting garden 3 which is a watering facility. A large number of holes 1a,... Are formed in the water collecting pipe 1 so as to collect rainwater that has penetrated into the ground. One end of the water collecting pipe 1 is protruded from the ground to the ground, and the pipe protruding end is a water pipe, which is branched into a first branch pipe 7a and a second branch pipe 7b, One branch pipe 7a leads to the pond 4 having a fountain, which is a hydrophilic facility on the ground, and the other branch pipe 7b leads to the underground storage tank 2. Each branch pipe 7a, 7
b is provided with automatic opening and closing valves 8 and 9, and the supply of water from the water collecting pipe 1 to the storage tank 2 and the pond 4 can be freely adjusted by opening and closing operations of the respective opening and closing valves. Solenoid valves, pinch valves and the like are used for the automatic opening and closing valves 8 and 9.

An overflow pipe 4a from the pond 4 is guided to the storage tank 2, and water that is no longer needed in the pond is not discharged as it is, but is stored in the storage tank 2 and is further used.

 2a is an overflow tube of the storage tank 2.

In the water sprinkling section 5, the water sprinkling section 5 includes a pump 5a as a water feeding driving means and a water sprinkling device 5b. The pump 5a is installed in the storage tank 2, and is connected to a watering device 5b provided on the planting garden 3 by a water supply pipe 5c. The timer 5 is connected to the pump 5a, and the pump is driven for a predetermined time by the timer.
Of water can be pumped to the watering device 5b, whereby water can be sprayed on the plant 3a through the nozzle of the watering device.

The rain detector 6 is installed at an appropriate position in the planting garden 3 on the ground, and is electrically connected to the pump 5a. When the rain detector 6 senses rainfall, the pump 5a can be driven for the set time of the timer 10.

 Next, the usage will be described.

 First, the case of rain will be described.

At this time, it is not necessary to sprinkle water on the planting garden 3 or supply water to the pond 4, so rainwater is exclusively stored. That is, the rain detector 6 senses rainfall and receives a signal from the rain detector to automatically open and close the valve.
8 and 9 are actuated, and one of the on-off valves 8 is "closed" and the other on-off valve 9 is "open", so that the rainwater of the collecting pipe is led to the storage tank 2, and the rainwater is stored in the storage tank. It is stored in the drainage pipe and in the ground around this drainage pipe, respectively. When the rainwater in the pond 4 overflows during rainfall, it is stored in the storage tank to be guided to the storage tank 2 through the overflow pipe 4a.

 Next, the fine weather will be explained.

At this time, since it is necessary to water the planting garden 3 and supply water to the pond 4, the stored rainwater is exclusively used. Therefore, one open / close valve 8 is opened and the other open / close valve 9 is closed.
As a result, rainwater that has penetrated into the ground gradually flows into the pond 4 through the water collecting pipe 1 to replenish the pond water that has been reduced due to evaporation or the like. After a certain period of time (for example, one day) has passed after the rain has finished falling, the stored rainwater is pumped from the storage tank 2 to the water sprinkling device 5b by the pump 5a, and water is sprinkled by the water sprinkling device.
Developing.

In the above example, instead of the timer 10, a moisture meter 12 is installed in the soil of the planting garden 3 as shown by a chain line in FIG. Rainwater may be supplied to the sprinkler 5b.

Another example of the water collecting section 1 is shown in FIGS. In this example, if there is an impermeable portion 13 such as concrete at a position below the planting garden 3 where the underground water collecting portion is to be provided, the water collecting groove 11 is provided on the upper surface thereof, and the water collecting groove is provided. A water supply pipe (only water supply pipe 7a is shown) is connected to the end of. Other configurations are substantially the same as those in the above example, and the same reference numerals are used for this purpose.

 The usage of this example is the same as that of the first example.

(Effects of the Invention) According to the present invention, it is expected that rainwater can be collected with a simple configuration and used repeatedly, so that rainwater can be used effectively and running costs in water use facilities can be reduced. From the point of view, enabling the installation of water use facilities of the required scale even in places where tap water is difficult to secure, and in the community, and furthermore, it can be expected that water will be recycled and used, increasing the efficiency of rainwater collection. And water resources can be secured.
