Description

  The present invention relates to a transfer type watering device, and more particularly to a mobile type watering device using a system that uses rainwater.

  In recent years, there has been a movement to actively reuse rainwater against the backdrop of growing environmental awareness. In areas where precipitation is low, it is desirable to use rainwater effectively. There are various methods of using general rainwater. For example, rainwater is stored in a tank and used for growing plants or for washing toilets. In some cases, rainwater is used to sprinkle trees and lawns in the home garden.

  By the way, when using rainwater, the degree of cleanness required differs depending on the intended use. For example, in the case of water that is directly touched by humans or used for washing dishes, advanced cleaning treatment is required. On the other hand, if the water is used for washing toilets or growing trees, high cleanliness is not required, and rainwater can be used as it is.

  However, in the watering system using rainwater, since the rainwater storage tank is fixed, the watering range is limited. In the case of a general rainwater utilization device, the cleanliness is determined in advance according to the intended use. For this reason, there was no idea of using differently clean water in one system.

  Accordingly, an object of the present invention is to provide a movable watering device that uses rainwater. Another object is to provide a rainwater utilization device that can supply water with different cleanliness depending on the application.

  According to an embodiment of the present invention, a mobile watering device is provided, and the mobile watering device discharges water stored in the watering tank to the surrounding environment. A nozzle for watering, a watering pump for sending water stored in the watering tank to the nozzle, a moving mechanism for moving the watering tank, the nozzle, and the watering pump, and power for the watering pump and the moving mechanism And a power source that provides power.

  According to one embodiment, in the mobile watering device, the power source is a solar cell panel, and the solar cell panel powers at least one of the moving mechanism and the watering pump.

  According to one embodiment, in the mobile sprinkler, the nozzle is configured to spray water in a mist.

  According to one embodiment, in the mobile watering device, the watering tank is configured to store rainwater.

  According to an embodiment of the present invention, a rainwater utilization system is provided, which includes a first tank for storing rainwater, a first piping system for feeding rainwater in the first tank, and a first tank. A two-piping system, a filter provided in the second piping system for cleaning rainwater, and a mobile watering device according to any embodiment of the present disclosure. Fluid connection is made by the piping system.

FIG. 2 is a diagram for explaining the flow of water in the second piping system. FIG. 2 (A) shows a state in which rainwater is supplied from the first tank, and FIG. FIG. 2 (C) is a diagram showing a state in which rainwater is supplied from the first tank and purified water is supplied to the use of the second piping system. is there. FIG. 3 is a schematic view showing a configuration of a mobile watering device according to an embodiment of the present invention.

  Hereinafter, a mobile watering device using a rainwater utilization system according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is an overall schematic diagram of a rainwater utilization system 1 according to an embodiment of the present invention. As shown in FIG. 1, in this embodiment, the 1st tank 3 for storing rainwater, the 1st piping system 11 and the 2nd piping system 31 for sending the rainwater of this 1st tank 3, and the 1st A filter 37 for cleaning rainwater is provided in the two piping system 31.

[First tank]
The first tank 3 is for directly storing rainwater that has fallen on the roof of the house H or the like. For this reason, a gutter (not shown) installed on the roof is drawn into the first tank 3. The first tank 3 can be made of various materials such as metal and polyethylene. The capacity of the first tank 3 is determined based on the rainfall characteristics of the area where it is installed. That is, it is not necessary to provide the first tank 3 having a large capacity in an area where it frequently rains. This is because rainwater is frequently replenished. On the other hand, in a region where it does not rain frequently, it is better to provide the first tank 3 having a large capacity. This is because it is necessary to store a large amount of rainwater when it rains.

  The first tank 3 of the present embodiment is fixedly installed together with the house H. However, it may be mobile. In the case of the mobile type, it is desirable that the connection with the gutter can be easily released. Further, the first tank 3 may be provided with a predetermined closing valve (not shown). This closing valve is for closing a rain gutter that introduces rain water when the rain water in the first tank 3 is full. The closing valve is connected to a float (not shown) in the first tank 3, and the closing valve closes the gutter when the float rises.

[First piping system]
The 1st piping system 11 is piping which sends the rainwater of the 1st tank 3 directly for various uses. Specific uses include toilet washing, car washing, watering plants, and use in a mobile watering device described below. These are applications where high cleanliness is not required for water. Needless to say, the present invention can be used for applications other than the above as long as it does not require high cleanliness.

[First pump]
The 1st pump 13 is a pump provided in the 1st piping system 11, and pressurizes and feeds the rainwater of the 1st tank 3 for the above-mentioned use etc. By installing the first pump 13, it is possible to send rainwater regardless of the height difference between the first tank 3 and the location where rainwater is used. However, when the 1st tank 3 exists in a position higher than a rainwater utilization place, the 1st pump 13 does not need to be provided.

[Solar panel and battery]
A solar cell panel 41 is connected to the first pump 13. This is for driving the first pump 13 without using a commercial power source. By using the solar cell panel 41, it is possible to completely separate the power supply of the house H, and there is no need to make a special reconstruction or the like for the house H. Moreover, the battery 43 is connected to the solar cell panel 41, and it is possible to drive the first pump 13 even when the solar cell panel 41 does not generate power, such as on a cloudy day or at night. .

[Second piping system]
Next, the second piping system 31 will be described. The second piping system 31 is for cleaning rainwater with a filter 37 and for sending the cleaned water for various uses. Specific applications include, for example, tableware and container washing, washing machines, and pools. Of course, it can be used for other purposes. The second piping system 31 is provided on the downstream side of the first tank 3 and includes a four-way valve 33, a second pump 35, a filter 37, and a second tank 39. As shown in FIG. 1, the second piping system 31 of the present embodiment is in a loop form based on the four-way valve 33. And the water supply pipe 40 for various uses is connected to the downstream of the four-way valve 33.

[Four-way valve]
The four-way valve 33 is for switching a flow path from the first tank 3, a flow path to the second pump 35, a flow path from the second tank 39, and a flow path for various uses. The four-way valve 33 is controlled by a control unit (not shown). The four-way valve 33 can completely block the flow of water, and can arbitrarily communicate each flow path. However, the four-way valve 33 is not essential.

[Second pump]
The second pump 35 is for pressurizing and feeding water from the second piping system 31. The specific configuration is the same as that of the first pump 13. The second pump 35 is also connected to the solar cell panel 41 via the battery 43 described above. In addition, the solar cell panel 41 and the battery 43 may share the thing for the 1st pump 13, and may provide for the 2nd pump 35 uniquely. The second pump 35 is also used for circulating water in the loop. This point will be described later. The second pump 35 is not necessarily essential to the present invention.

[filter]
The filter 37 is for cleaning rainwater. The filter 37 is filled with sand, gravel stones, etc., and rainwater is cleaned by passing through the filter 37. By filling the filter 37 with finely crushed charcoal or the like, it is also possible to generate water with higher cleanliness. However, a filter using fine chemical fibers or the like may be used.

[Second tank]
The second tank 39 is for storing the water purified by the filter 37. By using the second tank 39, it is possible to use purified water even when it is not raining. However, the second tank 39 is not essential to the present invention.

[Channel switching]
FIG. 2 shows various flow path switching states. FIG. 2A shows a state in which rainwater is supplied from the first tank 3, and neither circulation in the loop nor water supply to the application is performed. This is a stage in which water is stored in the second tank 39. FIG. 2B shows a state where water is circulating in the loop. This is a stage in which the water in the second tank 39 is circulated and the cleanliness of the water is increased by the filter 37. However, when the filter 37 has a high performance, water having the required cleanliness may be obtained by passing the filter once. In this case, the circulation is not necessary. Further, FIG. 2C shows a state in which rainwater is introduced from the first tank 3 and at the same time purified water is sent to the application.

[Action]
Next, the operation of the rainwater utilization apparatus according to the present embodiment will be described again with reference to FIG. First, when it rains, rainwater collects from the roof of the house H to the rain gutter. This rainwater is introduced into the first tank 3 by rain gutters. The rainwater in the first tank 3 is used for applications where high cleanliness is not required by the action of the first pump 13. On the other hand, rainwater supplied from the first tank 3 to the second piping system 31 by the action of the second pump 35 is purified through the filter 37. The purified water is stored in the second tank 39. At this time, the water purified by the action of the four-way valve 33 circulates in the loop of the second piping system 31 or is sent for various purposes.
