The pump is configured to be driven when the temperature difference exceeds a predetermined temperature.

  Moreover, in this invention which concerns on Claim 4, in this invention which concerns on any one of the said Claims 1-3, the said storage tank is a storage battery from a generator, when the river water for the whole capacity | capacitance is stored. It was decided that the electric capacity to be stored was larger than the electric capacity discharged from the storage battery to the pump when the river water for the entire capacity was sprayed.

  And in this invention, there exists an effect described below.

  That is, according to the present invention, in the river water utilization system, a storage tank for cooling and storing the river water when the river level rises above the predetermined water level is connected to the river via the communication channel, and stored. A watering tool for spraying the cooled river water stored in the tank to the surface of the structure is connected to the storage tank via a pump, and the pump is connected to a generator interposed in the communication channel via a storage battery.

  Further, in the present invention, the capacity of the storage tank is the electric capacity stored in the storage battery from the generator when the river water for the entire capacity is stored, and from the storage battery when the river water for the entire capacity is sprayed. Since it is made larger than the electric capacity discharged to the pump, water can be sprayed only with the electric power stored when the river water is stored.

  Below, the specific structure of the river water utilization system which concerns on this invention is demonstrated, referring drawings.

  As shown in FIG. 1, in the river water utilization system 1 according to the present invention, a storage tank 3 is buried underground in the basin of the river 2, and the river 2 and the storage tank 3 flow at a predetermined height of the river 2. A communication channel 5 provided with an inlet 4 is connected in communication.

  Thereby, in the river water utilization system 1, the river water 6 is stored in the storage tank 3 from the river 2 when the water level of the river 2 rises above the predetermined water level.

  In the river water utilization system 1, a generator G is installed in the middle of the communication channel 5, and a storage battery 8 is connected to the generator G via a controller 7.

  Thus, in the river water utilization system 1, when the river water 6 flows from the river 2 into the storage tank 3 due to a rise in the water level of the river 2, the generator G is activated to generate power and store in the storage battery 8. I have to.

  Further, the river water utilization system 1 has a watering device 10 installed on a road 9 that is a structure, a storage tank 3 is connected to the watering device 10 via a communication pipe 11, and a pump P is provided in the middle of the communication pipe 11. The storage battery 8 is connected to the pump P via the controller 7.

  Thus, in the river water utilization system 1, the pump P is driven by the storage battery 8 so that water is sprayed from the watering tool 10 toward the surface of the road 9.

  Moreover, the river water utilization system 1 accommodates a cooler C inside the storage tank 3, and a storage battery 8 is connected to the cooler C via a controller 7.

  Thus, in the river water utilization system 1, the river water 6 stored in the storage tank 3 can be cooled by driving the cooler C with the storage battery 8.

  Furthermore, the river water utilization system 1 arranges the temperature sensor 12 on the surface of the road 9, arranges the temperature sensor 13 inside the storage tank 3, and connects these temperature sensors 12 and 13 to the controller 7. .

  Thereby, in the river water utilization system 1, the temperature sensors 12 and 13 can be used to measure the surface temperature of the road 9 and the water temperature of the river water 6 stored in the storage tank 3, respectively.

  In the river water utilization system 1 configured as described above, when the water level of the river 2 rises above a predetermined water level due to heavy rain, the river water 6 flows from the river 2 into the storage tank 3 via the communication channel 5, thereby The generator G is activated and the storage battery 8 is charged.

  Thereafter, in the river water utilization system 1, the controller 7 indicates that the river water 6 flowing through the communication channel 5 has decreased due to rain, and that the electromotive force generated by the generator G has dropped below a predetermined voltage. If detected, the controller 7 drives the cooler C with the storage battery 8 to cool the river water 6 stored in the storage tank 3.

  Thereafter, in the river water utilization system 1, the controller 7 detects the surface temperature of the road 9 and the water temperature of the river water 6 stored in the storage tank 3 with the temperature sensors 12 and 13, and the temperature sensors 12 and 13 detect them. When the temperature exceeds a predetermined temperature difference, the controller 7 drives the pump P with the storage battery 8 to spray the river water 6 stored and cooled in the storage tank 3 from the watering tool 10 toward the surface of the road 9. . Thereby, the surface of the road 9 which is a structure is cooled.

  The river water utilization system 1 is not limited to the case where the surface temperature of the structure and the water temperature of the river water 6 are equal to or greater than a predetermined temperature. When the surface temperature is equal to or higher than the predetermined temperature, the water temperature is the predetermined temperature. You may make it water the case when it becomes below.

  The river water utilization system 1 is not limited to the road 9 and may be sprayed to any structure such as a building, a house, or a pond, and can be sprinkled to a roadside green space or a rooftop garden. For this purpose, water can be sprayed, and further, the stored river water 6 may be purified and then sprayed.

Water may be sprayed by the pump P, and the remaining river water 6 may be discharged again from the drain of the storage tank 3 to the river 2.

  As described above, in the river water utilization system 1, the storage tank 3 for cooling and storing the river water 6 is stored via the communication channel 5 when the water level of the river 2 rises above the predetermined water level. A sprinkler 10 for sprinkling the cooled river water 6 stored in the storage tank 3 to the surface of the structure is connected to the storage tank 3 via the pump P and connected to the river 2, and connected to the communication channel 5. Since the pump P is connected to the installed generator G via the storage battery 8, the structure can be cooled using the river water 6 stored in the storage tank 3 during heavy rain, so natural energy can be reduced. The river water 6 can be used effectively for cooling the structure.

  In the river water utilization system 1, since the pump P is driven by the storage battery 8 when the electromotive force generated by the generator G becomes a predetermined voltage or less, the river water 6 is wasted in rainy weather. The structure can be cooled by effectively using the limited river water 6.

  Further, in the river water utilization system 1, temperature sensors 12 and 13 are disposed in the structure and the storage tank 3, respectively, and a pump is detected when the temperature detected by both the temperature sensors 12 and 13 exceeds a predetermined temperature difference. Since it is configured to drive P, the structure can be cooled by using the limited river water 6 more effectively.

  Further, in the river water utilization system 1, when the capacity of the storage tank 3 is the river water 6 for the entire capacity, the electric capacity stored in the storage battery 8 from the generator G is the river water for the entire capacity. When it is set to be larger than the electric capacity discharged from the storage battery 8 to the pump P when the water 6 is sprayed, the water can be sprayed only with the electric power stored when the river water 6 is stored. .
