<F> Configuration of Water Receiving Unit (FIG. 1) The water receiving unit 3 stores water sent from the water intake tank 14 via the water supply unit 2 and supplies the water to the construction site 4 that requires water supply. It is a device to send out. The water receiving section 3 includes a water receiving tank 31, a water supply pump 32, and a water supply pipe 33. Receiving tank 3
1 uses a steel box having a volume capable of storing a required amount of water. The water supply pump 32 uses a known device that sends out water in the water receiving tank. As the water supply pipe 33, known pipes suitable for sending water stored in the water receiving tank 31 to a water supply place are used.

<G> Installation of Water Supply System (FIG. 1) First, the water intake unit 1 is installed upstream of a predetermined river. The intake pump 11 is installed in the river. Next, the water receiving section 3 is installed on the downstream side of the river. A water supply pipe 33 is installed between the water receiving section 3 and the construction site 4. Then, a water supply pipe 21 is installed between the water intake unit 1 and the water reception unit 3 as the water supply unit 2. A water supply pipe 33 is installed between the water receiving section 3 and the construction site 4. Here, a part of the water supply pipe 21 is installed at a high position. (FIG. 1) Thereafter, the air suction tool 22 is attached to the water supply pipe 21. The air suction tool 22 is provided at a portion of the water supply pipe 21 installed at a position higher than the other part, with the suction part 221 facing upward so as to be orthogonal to the upper part of the water supply pipe 21, and A screw is screwed into a female screw hole provided in the water supply pipe 21 and attached. (FIG. 3) The attachment of the air suction tool 22 is not limited to the screw method, and may be a known method such as welding, as long as the air suction tool 22 is attached so that air does not leak from the attachment portion. As a result, it is possible to stop the outflow of water in the water supply pipe 21 due to the siphon phenomenon after the water supply apparatus is stopped by sucking air from the attachment portion into the water supply pipe 21.
Furthermore, a full-water sensor and a drought sensor may be attached to the water intake tank 14 and the water receiving tank 31 in some cases. This full water sensor is attached to a portion corresponding to a predetermined water level at which water supply is to be stopped. The drought sensor is attached to a portion corresponding to a predetermined water level at which water storage is required. One end of the water supply pipe is connected to a water supply pump, and the other end is installed at a construction site where water is supplied. Finally, the water supply device is activated to supply water to the construction site 4.

<H> Control of Water Supply Unit The control of the water supply unit is performed by the water intake tank 1 and the water receiving tank 3 of the water receiving unit 3.
1 is performed based on the water storage amount. The control of the water supply device is performed by a known control method using a computer or the like.

<Re> Content of control at the time of water intake When the water level drops to the location of the water shortage sensor in the water intake tank 14 of the water intake unit 1, the water intake pump 11 is operated to pump water from a predetermined river, and through the water intake pipe 12. Control is performed so that water is supplied to the water intake tank 14. On the other hand, the intake tank 1
When the water level rises to the full-water sensor installation position of 4, the intake pump 11 is stopped, and control is performed so that the pumping of water from the river and the supply of water are not performed.

<Nu> Content of control at the time of drought When the water level drops to the installation position of the drought sensor in the water receiving tank 31 of the water receiving part 3 by supplying water to the construction site 4, when the stop valve 223 is closed. At the same time, the water supply pump 15 of the water intake unit 1 is controlled to operate. As a result, the suction of air into the water supply pipe 21 is stopped, and water is supplied from the water intake unit 1 to the water receiving unit 3 to be stored.

<R> Content of control when water is full On the other hand, when water is received up to the installation position of the full water sensor in the water receiving tank 31, the water supply pump 15 of the water intake unit 1 stops and the stop valve 223 of the air suction tool 22 is simultaneously operated. Control to open. Then, air is sucked into the water supply pipe 21. As a result, the siphon phenomenon is eliminated by the decrease in the water pressure and the weight of the valve plate, and the water in the water supply pipe 21 stops.

[0024]

According to the water supply apparatus of the present invention, the following effects can be obtained from the above description. <B> Air can be sucked into a water supply pipe installed at a position higher than other parts of the water supply pipe. As a result,
The outflow of water in the water supply pipe after the water supply device stops due to the siphon phenomenon can be stopped. <B> Water can be stored in the water intake tank after passing the water through the suspended matter removing device. As a result, it is possible to prevent a floating substance such as a tree leaf from being mixed into the water supply device.
