Description

Automatic Watering System for Rooftop Greenery {Water supply system for green roof}

The present invention relates to a roofing watering system for roofing, and more particularly, a rooftop for storing rainwater that cannot be used to flow into sewage in advance and automatically spraying it on the roofing soil when water content is insufficient in the soil. It relates to an automatic watering system for recording.

The roof garden has great potential in that it can create as much green space as the building occupies. The planar elements that make up a city include buildings, roads, and public notices. Among them, more than half of the buildings, less than 25% of the roads, and other public notices such as parks and rivers.

If you can record all of the rooftops of the city, it will be healthy, colored in green except for roads.

The roof garden has great significance in terms of environment. Directly, it is possible to alleviate urban heat islands, make effective use of rainwater, purify the air according to the growth of plants, and improve the landscape. Etc. can be mentioned. The use of roof gardens is becoming more diverse and important, and it is also an important tool for increasing the value of buildings and improving the company's image.

In order to create a roof garden, much consideration should be given to the planting base. Planting bases include drainage, soil, vegetation, boundary between components, landscaping installation, watering and maintenance.

Drainage is an important component of rooftop landscaping as well as waterproofing. Because it greatly affects the growth of plants and the safety of the structure, it should be designed considering the characteristics of the region and plants. To this end, it is required to secure the slope and the size and quantity of drains, and to secure the drainage channels. In particular, a drainage system is needed to prepare for heavy rains during the rainy season.

Soil can be divided into a drainage soil layer for drainage and a growing soil layer that supplies nutrients to trees. In addition to the weight reduction of soil materials, breathability, moisture retention, stability, and workability should be considered. In general, a shallow soil deepening rooftop recording system is composed of artificial light soil, and in the case of a deep soil deep soil type, a soil layer is formed. And when the top of the soil layer is composed of lightweight soil, it is easy to fly or weather, so lay natural volcanic rocks.

Vegetation trees should be planted in consideration of the growth and development characteristics of each plant. In addition, the roofing plants must be basically dry, cold and moisture resistant and adaptable to strong solar radiation and wind. Because of this, ground cover plants and herbaceous plants are used a lot. Avoid ornamental arboreals.

Neglecting the boundary between the components when recording the rooftop may cause decisive defects due to drainage of the entire rooftop during heavy rains. Therefore, in order to prevent waste of reconstruction to compensate for this, it is necessary to secure each boundary in advance.

When installing landscaping facilities, it is necessary to examine in advance whether the fixing method is not likely to damage the rooftop floor. If possible, the anchoring method should be avoided, and a design to prevent breakage of the waterproof layer by a method such as assembly or fitting is necessary. In addition, arranging facilities and connecting lights such as tree seeing in connection with the main line is also an important factor to consider in the rooftop landscape.

Finally, irrigation varies with area and vegetation. In particular, the roof garden should not neglect watering. Rooftops are always exposed to solar radiation, and moisture easily evaporates, so care must be taken in irrigation and subsequent maintenance to keep vegetation healthy.

Typically, rainwater (water) penetrates into the soil constituting the roof garden and is used by plants, or a large amount of water is drained through drains and discarded. This rainwater is no longer utilized and flows into rivers or groundwater.

In addition, watering facilities generally used for roof gardens are mainly used for general water, which is expensive. Therefore, there is a need for a method of optimizing the effort and cost required for maintenance by replacing the normal constant by using the rainwater that is naturally left unattended and using it as watering for the roof garden.

The present invention has been made to solve the problems of the prior art as described above, the purpose of which is to store the rainwater that can not be used to flow into the sewage in advance, when the water content in the soil is insufficient for the rooftop greening soil It is to provide an automatic watering system for roofing greenery that can be sprayed on.

1 is an overall system configuration of an automatic watering system for rooftop recording according to the present invention.

When rainwater (water) reaches the rainwater inlet of the tank 5 along the drain 1, foreign matter is filtered by the filter 2 installed in the inlet, and only rainwater flows into the tank 5.

In the tank 5, a submersible pump 7 in which the motor 6 is mounted is installed at the lower part, and the motor is connected to the external power supply 12. Preferably, when the external power supply unit 12 is configured as a solar cell that converts sunlight into a current, energy required for rooftop recording can be greatly reduced.

In the tank 5, a water level measurement sensor 14 is provided. The water level measurement sensor 14 measures the water level 13 in the tank 5 and generates a signal for controlling the flow control valve 4 to supply a constant from the general water source 3 when the water level is below a certain level.

The soil moisture measurement sensor 11 measures the water content in the rooftop soil 1 and generates a control signal for driving the motor 6 to operate the underwater pump 7 when the water content is insufficient.

As a control signal is generated, the rainwater stored in the tank 5 is sprayed on the soil through the water sprayer 9 via the discharge pipe 8. At this time, the sprinkler 9 may be a sprinkler or a drip irrigation pipe.

Referring to the operation of the configuration according to the present invention in more detail below.

The soil moisture measurement sensor 11 measures the amount of water present in the planting layer (top) of the soil 10. In FIG. 1, the lower end of the soil 1 means a drainage layer.

When the measurement sensor 11 recognizes that the soil planting layer lacks moisture, the sensor 11 sends a control signal to the motor 6 to drive water to drive the motor. When the motor is operated, the water in the tank is sprinkled out through the drain pipe 8 by the submersible pump 7 connected to the motor.

The tank 5 is always supplemented with a certain amount of water, which can be maintained by the incoming rainwater and the supplementary general constant. That is, when water in the soil is insufficient in the period of large amounts of solar radiation such as summer, when the water level 13 in the tank is lowered, the water level measurement sensor 14 detects this and is connected to the general water source 3. Automatically open the flow control valve (4).

The flow control valve 4 may be a ball valve or a diaphragm type, which is controlled to open and close by an actuator operated by the water level measurement sensor 14 provided at the top. Here, the flow control valve is used to include not only a valve for controlling the flow rate but also a valve operated only on / off.

When the constant water level reaches a certain level due to the inflow of general water, the water level measurement sensor 14 closes the flow control valve 4 to block the inflow of water.

All of this is done automatically and the necessary power can be supplied from the power stored in the external solar cell.

Furthermore, the automatic roofing watering system for roofing according to the present invention may be provided with a container for storing seeds on one side of the tank so that not only as a watering device but also seeding of seeds at the time of seeding together with watering.

Preferably, such a container may be controlled so that the seed is opened downward at the time of spraying the water so that the seed may fall into the water in the tank by gravity.
