以下に、本発明に係る雨水利用システムの具体的な構成を図面を参照しながら説明する。   Below, the concrete structure of the rainwater utilization system which concerns on this invention is demonstrated, referring drawings.

図１に示すように、本発明に係る雨水利用システム１では、建物２の屋根３の前端側に雨水を集水するための集水具４を配設している。   As shown in FIG. 1, in the rainwater utilization system 1 according to the present invention, a water collecting tool 4 for collecting rainwater is disposed on the front end side of a roof 3 of a building 2.

この集水具４は、屋根３の前端縁に雨樋５を取付け、雨樋５の左端に集水管６の始端部を連通連結しており、この集水管６の終端部を地中に埋設した貯留タンク７に連通連結している。   The water collecting tool 4 has a rain gutter 5 attached to the front edge of the roof 3, and the start end of the water collecting pipe 6 is connected to the left end of the rain gutter 5, and the terminal end of the water collecting pipe 6 is buried in the ground. The storage tank 7 is connected in communication.

また、雨水利用システム１では、建物２の屋根３の後端側に屋根３に向けて散水するための散水具８を配設している。   In the rainwater utilization system 1, a watering tool 8 for spraying water toward the roof 3 is disposed on the rear end side of the roof 3 of the building 2.

この散水具８は、屋根３の後端縁と右端にＬ字状の散水管９を配管しており、屋根３に設けた菜園10に向けて散水するための散水ノズル11を散水管９の先端部に形成するとともに、屋根３に向けて散水するための散水ノズル12を散水管９の中途部に形成し、さらには、屋根３に取付けた太陽発電パネル13に向けて散水するための散水ノズル14を散水管９の基端部に形成している。この散水具８は、散水管９の基端部に貯留タンク７をポンプ15を介して連通連結している。   The watering tool 8 has an L-shaped watering pipe 9 piped at the rear edge and right end of the roof 3, and a watering nozzle 11 for watering the vegetable garden 10 provided on the roof 3 is provided on the watering pipe 9. Sprinkling nozzles 12 are formed in the middle of the sprinkling pipe 9 and sprinkled toward the solar power generation panel 13 attached to the roof 3. A nozzle 14 is formed at the proximal end of the water spray tube 9. In the watering tool 8, a storage tank 7 is connected to a base end portion of a watering pipe 9 through a pump 15.

このように、雨水利用システム１では、建物２の屋根３に集水具４と散水具８とをそれぞれ配設するとともに、集水具４に貯留タンク７を接続し、貯留タンク７にポンプ15を接続し、ポンプ15に散水具８を接続している。   Thus, in the rainwater utilization system 1, the water collecting tool 4 and the watering tool 8 are respectively disposed on the roof 3 of the building 2, the storage tank 7 is connected to the water collecting tool 4, and the pump 15 is connected to the storage tank 7. The watering tool 8 is connected to the pump 15.

これにより、雨水利用システム１では、集水具４で雨水を集水し、その雨水を地中に埋設した貯留タンク７で冷却しながら貯留しておき、ポンプ15を駆動することによって、散水具８から屋根３及び屋根３に設けた菜園10や太陽発電パネル13に向けて散水するようにしている。   Thus, in the rainwater utilization system 1, the rainwater is collected by the water collecting tool 4, stored while being cooled by the storage tank 7 buried in the ground, and the pump 15 is driven, thereby the watering tool. Water is sprayed from 8 to the garden 3 and the solar power generation panel 13 provided on the roof 3 and the roof 3.

特に、上記雨水利用システム１では、集水具４の雨樋５と散水具８の散水ノズル12とを屋根３の前後端に対向させて配置して、散水具８の散水ノズル12から散水された雨水を集水具４の雨樋５で再び集水できるようにしており、これにより、雨水を循環して利用できるようにしている。   In particular, in the rainwater utilization system 1, the rain gutter 5 of the water collecting tool 4 and the watering nozzle 12 of the watering tool 8 are arranged facing the front and rear ends of the roof 3, and water is sprayed from the watering nozzle 12 of the watering tool 8. The rainwater can be collected again by the rain gutter 5 of the water collecting tool 4 so that the rainwater can be circulated and used.

また、雨水利用システム１では、屋根３に太陽発電パネル13を設置するとともに、太陽発電パネル13に蓄電池16を接続しており、この蓄電池16をコントローラ17を介してポンプ15に接続している。   In the rainwater utilization system 1, the solar power generation panel 13 is installed on the roof 3, and the storage battery 16 is connected to the solar power generation panel 13, and the storage battery 16 is connected to the pump 15 via the controller 17.

これにより、雨水利用システム１では、太陽発電パネル13で太陽光エネルギーを電気エネルギーに変換して蓄電池16に蓄電し、必要に応じてコントローラ17を介して蓄電池16からポンプ15に電気エネルギーを供給してポンプ15を駆動するようにしている。   Thereby, in the rainwater utilization system 1, solar energy is converted into electric energy by the solar power generation panel 13 and stored in the storage battery 16, and electric energy is supplied from the storage battery 16 to the pump 15 via the controller 17 as necessary. The pump 15 is driven.

さらに、雨水利用システム１では、屋根３の表面に温度センサー18を取付けるとともに、貯留タンク７の内部に温度センサー19を取付け、これらの温度センサー18,19をコントローラ17に接続している。   Further, in the rainwater utilization system 1, a temperature sensor 18 is attached to the surface of the roof 3, a temperature sensor 19 is attached to the inside of the storage tank 7, and these temperature sensors 18, 19 are connected to the controller 17.

そして、雨水利用システム１では、コントローラ17が温度センサー18,19を用いて屋根３の表面の屋根温度と貯留タンク７の内部の雨水温度とを検出し、屋根温度が雨水温度よりも所定温度以上高くなって屋根温度と雨水温度とが所定温度差以上となった場合には、コントローラ17が蓄電池16とポンプ15とを接続してポンプ15を駆動し、貯留タンク７に貯留された雨水を散水具８を用いて散水するようにしている。   In the rainwater utilization system 1, the controller 17 detects the roof temperature on the surface of the roof 3 and the rainwater temperature inside the storage tank 7 using the temperature sensors 18 and 19, and the roof temperature is equal to or higher than the rainwater temperature by a predetermined temperature. When the temperature rises and the roof temperature and rainwater temperature exceed a predetermined temperature difference, the controller 17 connects the storage battery 16 and the pump 15 to drive the pump 15 to spray the rainwater stored in the storage tank 7. Water is sprayed using the tool 8.

なお、雨水利用システム１では、屋根温度と雨水温度とが所定温度差以上となった場合に限られず、屋根温度が所定温度以上となった場合、雨水温度が所定温度以下となった場合、室内温度が所定温度以上となった場合、室内温度と雨水温度とが所定温度差以上となった場合などに散水するようにしてもよい。   Note that the rainwater utilization system 1 is not limited to the case where the roof temperature and the rainwater temperature are equal to or greater than the predetermined temperature, but when the roof temperature is equal to or higher than the predetermined temperature, the rainwater temperature is equal to or lower than the predetermined temperature, Water spraying may be performed when the temperature exceeds a predetermined temperature or when the room temperature and the rainwater temperature exceed a predetermined temperature difference.

また、雨水利用システム１では、建物２の内部や外部に消化設備を配設し、この消化設備をポンプ15に接続して、ポンプ15を駆動することによって消火設備から消化のための放水を行えるようにすることもできる。これにより、建物２の内外での火災に備えることができる。   In addition, in the rainwater utilization system 1, digestion equipment is arranged inside or outside the building 2, and this digestion equipment is connected to the pump 15, and the pump 15 is driven to discharge water for digestion from the fire extinguishing equipment. It can also be done. Thereby, it can prepare for the fire inside and outside the building 2.

以上に説明したように、上記構成の雨水利用システム１では、自然エネルギーだけを用いて雨水を冷却しながら貯留するとともに建物２の屋根３に向けて散水するようにしている。   As described above, in the rainwater utilization system 1 configured as described above, rainwater is stored while being cooled using only natural energy, and water is sprayed toward the roof 3 of the building 2.

そのため、上記雨水利用システム１では、散水によって建物２の屋根３や側壁などの外壁温度を低下させることができ、これにより、建物２の内部温度をも低下させることができ、冷房設備によるエネルギー消費を低減することができる。   Therefore, in the rainwater utilization system 1, the outer wall temperature of the roof 3 and the side walls of the building 2 can be lowered by watering, whereby the internal temperature of the building 2 can also be lowered, and the energy consumption by the cooling equipment Can be reduced.

しかも、上記雨水利用システム１では、集水具４と散水具８とを建物２の屋根３に配設しているために、散水具８で散水した雨水を集水具４で集水することができ、これにより、雨水を循環して利用することができ、夏場の少雨時期でも雨水利用システム１を稼動して建物２を冷却することができる。   Moreover, in the rainwater utilization system 1, since the water collecting tool 4 and the watering tool 8 are arranged on the roof 3 of the building 2, the rainwater sprayed by the watering tool 8 is collected by the water collecting tool 4. As a result, rainwater can be circulated and used, and the rainwater utilization system 1 can be operated and the building 2 can be cooled even in the rainy season of summer.

また、上記雨水利用システム１では、太陽発電パネル13を建物２の屋根３に配設するとともに、太陽発電パネル13の表面に向けて散水具８の散水ノズル14から雨水を散水するようにしているために、太陽発電パネル13の表面を散水具８から散水した雨水で洗浄することができるので、太陽発電パネル13の清掃作業を軽減することができるとともに、表面が汚れることに起因する太陽発電パネル13での発電効率の低下を防止することができる。   In the rainwater utilization system 1, the solar power generation panel 13 is disposed on the roof 3 of the building 2, and rainwater is sprinkled from the water spray nozzle 14 of the water sprinkler 8 toward the surface of the solar power generation panel 13. Therefore, since the surface of the solar power generation panel 13 can be washed with rain water sprayed from the water sprinkler 8, the cleaning operation of the solar power generation panel 13 can be reduced, and the solar power generation panel caused by the surface becoming dirty A reduction in power generation efficiency at 13 can be prevented.

さらに、上記雨水利用システム１では、建物２の屋根３と貯留タンク７に温度センサー18,19をそれぞれ配設し、両温度センサー18,19で検出された温度が所定温度差以上となった場合にポンプ15を駆動するようにしているために、限られた雨水をより一層有効利用して建物２を冷却することができる。   Further, in the rainwater utilization system 1, when the temperature sensors 18 and 19 are respectively disposed on the roof 3 and the storage tank 7 of the building 2 and the temperature detected by the temperature sensors 18 and 19 exceeds a predetermined temperature difference. Since the pump 15 is driven, the building 2 can be cooled by using the limited rainwater more effectively.
