Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention significantly reduces man-hours and costs for artificial maintenance by using natural energy (wind power, sunlight, rainwater) and enables suitable plant growth. A planting system with a hybrid irrigation device.

[0002]

2. Description of the Related Art In recent years, when building a building of a certain size or larger in Tokyo, greening of the roof has become obligatory. In addition, some municipalities subsidize the costs for securing plantation space within the residential area. However, in order to maintain and manage the rooftop planting of the building, a water supply device for irrigation, a power supply device for operating and controlling the device, a facility for draining excess rainwater, etc. are required separately. Further, these devices function by supplying power from the outside.

[0003]

In a general rooftop planting apparatus, an existing drainage mechanism is used for draining excess rainwater, and the water source of the irrigation equipment is the water supply to the building. The power supply is the power supplied to the building.
Compared with planting on the ground, rooftop planting requires additional costs such as electricity and water for maintenance. Therefore, when planting on the rooftop, it is necessary to introduce an irrigation system that does not require the labor and cost of maintenance similar to the planting on the ground surface.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above circumstances, and includes a planting device, a rainwater storage device, an irrigation pump, a wind power generation mechanism, and / or a wind power generation device, which is disposed on the roof or outer wall of a building. It consists of a power supply device equipped with a solar power generation mechanism,
The rainwater that has fallen mainly on the rooftop and its surroundings or the planting device is guided to the rainwater storage device, and wind and sunlight are converted into electric power by the power supply mechanism and supplied to the irrigation pump, which is then supplied to the irrigation pump. TECHNICAL FIELD The present invention relates to a planting system with a hybrid irrigation device, which is characterized by irrigating water collected in a rainwater storage device to plants of a planting device. Further, it is desirable that the power supply device includes a power storage control device. Further, it is desirable that the power supply device can set an optimum wind power generation mechanism and / or solar power generation mechanism according to the sunshine, wind environment, and space on the roof. Further, the rainwater storage device may be provided with a mechanism for suppressing the pollution of rainwater, the generation of pests, etc., and the power may be supplied to the mechanism from the power supply device. In addition, drainage generated from the cooling equipment may be guided to the rainwater storage device.

The planting system of the present invention can be applied to various buildings, and is not limited to the specifications of the roof or outer wall surface of a particular building. For example, it can be installed on flat roofs such as those seen on the rooftops of various buildings and condominiums, general houses, and pitched roofs of factories. In addition, it is possible to introduce an optimal planting system according to the sunshine on the rooftop, the wind environment, and the space at the installation site.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION As described above, the planting system of the present invention comprises a power supply device including a planting device, a rainwater storage device, a watering pump, a wind power generation mechanism and / or a solar power generation mechanism.

The planting device is composed of soil, plants, and a frame for holding the soil. The soil structure and the plants are not limited in any way, and some plants such as sedum do not need soil. It can be selected appropriately. Further, it is desirable that the frame holding the soil be provided with a heat insulating layer that does not transfer solar heat to the rooftop surface. In particular, it is extremely preferable that the heat insulating layer is made of a water impermeable material because it also serves as a waterproof layer.
In addition, a root preventive sheet, a planting base mat, and the like already known as this type of planting device can be appropriately used. Furthermore, the surface of the heat-insulating layer (preferably the waterproof heat-insulating layer) may be provided with a recess having an appropriate shape or the like to serve as a discharging means for promptly discharging the rainwater that has fallen to the surface layer. By providing such a discharging means, an excessive amount of water does not stay, so that a desirable environment for growing plants is provided. Further, since the concave portion as the drainage means also functions as the ventilation layer, it contributes to the improvement of the heat insulating property. Further, it is extremely preferable for the growth of plants (sedum) which require almost no water because the wet condition is avoided. Also,
On the surface of the heat insulating layer (preferably waterproof heat insulating layer), a concave portion having an appropriate shape may be formed, and a part of rainwater that permeates from the surface layer may be stored in the concave portion to serve as a water retaining means. This water retaining means is extremely preferable for the growth of most plants except the sedum species, especially in the season when the rainfall is scarce.

Under the planting device, that is, below the heat insulating layer (preferably the waterproof heat insulating layer), even if rain water penetrates from the joint (joint portion) of the heat insulating material, the rain water will be on the waterproof layer on the rooftop surface. It is desirable to lay a waterproof material (exterior material) that prevents contact between the two. In addition, it is desirable to collect rainwater in one direction with a slope, especially on flat roofs.

The rainwater storage device collects and stores an excessive amount of rainwater received by the planting device, and the soil and sand contained in the collected water settles during storage, so that it is clean. Water can also be delivered to the irrigation pump.

The wind power generator used as the power supply device is a system for rotating a generator by a wind turbine, and the wind turbine may be a vertical axis wind turbine, a horizontal axis wind turbine, or the like.

The solar power generation mechanism used as a power supply device is a system composed of a solar cell array, a power conditioner, a storage battery, a wiring and a connection box for connecting these, a watt hour meter, and the like. It may be selected depending on the system type, the independent type, the load type, and the like. Further, the solar battery cell may be selected from single crystal, polycrystal, amorphous and the like.

Further, this power supply device is used for the rooftop sunshine and
Optimal wind power generation mechanism and / according to the wind environment and space
Alternatively, if the solar power generation mechanism can be set, efficient power generation can be performed. As such a mechanism, any known mechanism may be adopted. For example, in the case of a wind power generation mechanism, a mechanism in which the wind turbine can be varied in the direction in which it receives the strongest wind power, and in the case of a solar power generation mechanism Corresponds to a mechanism that can change the angle to receive the strongest sunlight.

Further, when the rainwater storage device is provided with a mechanism for suppressing the pollution of rainwater, the generation of pests, etc., and the power is supplied from the power supply device to the mechanism, the rainwater is purified and the generation of mosquitoes is suppressed. The generation of unpleasant odor can also be suppressed.
As such a mechanism, any known mechanism may be adopted, but for example, a configuration in which a septic tank is provided in the middle of a path for circulating water by a pump or the like is equivalent.

If the wastewater generated from the cooling equipment is guided to the rainwater storage device, the water for daily use is prioritized in the summer and the like, for example, in the extreme heat when the amount of rainfall is insufficient and water supply is restricted. Since it is indispensable to operate the cooling equipment, it is possible to secure the amount of water that prevents plant depletion by guiding the wastewater generated from the cooling equipment to the rainwater storage device and making effective use thereof.
