欠点があつた。BACKGROUND ART Conventionally, a hydroponic cultivation method is known as an improved version of a hydroponic cultivation method. This method compensates for the lack of oxygen in the culture solution by blowing oxygen or air into the culture solution. Therefore, when performing hydroponic cultivation, it is possible to grow plants more effectively by applying water intermittently rather than continuously, and
It is known to be able to grow healthy plants. However, conventional hydroponic cultivation equipment has a complicated structure for intermittently supplying culture solution to plants, is expensive, and also suffers from vibrations etc. when performing hydroponic cultivation on a ship. There was a drawback that the culture solution overflowed.

3 is a water supply pipe; 4 is a drainage pipe; 5 1 to 5 4 are hydroponic cultivation tanks; 10 is an intermittent water supply device according to the present invention; The air pump 1 is arranged opposite to the discharge port 1a of the air pump 1. Therefore, the compressed air discharged from the air pump 1 is introduced into the water supply pipe 3, and is supplied from the water supply port end 3b of the water supply pipe 3 to the intermittent water supply device 10 according to the present invention.
This allows sufficient oxygen to be included in the culture solution. The intermittent water supply device 10 stores the culture solution supplied as described above, and when the culture solution reaches a predetermined amount, the predetermined amount of the culture solution stored as described later is passed through the drain pipe 4 to the lower part thereof. It is intermittently supplied to the installed hydroponic cultivation tank 51 .
5 1 to 5 4 are hydroponic cultivation tanks, which are arranged in a shelf (not shown) so as to be inclined as shown. Therefore, as described above, the upper hydroponic cultivation tank 5 1
The culture solution supplied to the tank sequentially flows to the lower hydroponic cultivation tanks 5 2 to 5 4 , and finally returns to the culture solution tank 2 from the discharge end 5 a, whereby each hydroponic cultivation tank 5 1 ~ 54 is intermittently supplied with culture solution.

が、本発明による間欠給水装置は、上記以外にも
種々応用可能であることは容易に理解できよう。 The intermittent water supply device 10 according to the present invention stores the liquid supplied from the water supply pipe 3 as described above. A floating member 1 disposed in the tank so as to face the opening 12
3, and a guide net member 14 for making the floating member 13 face the opening 12, and the drain pipe 4 forms a siphon together with the outlet end 4a, so that the closed tank 11 As the amount of water in the tank increases, the opening 12 is first closed by the floating member 13, and then, when more water is supplied, the tank 11
The water pressure inside increases, and the culture solution inside the tank 11 finally flows out through the drain pipe 4. Since this drain pipe 4 constitutes a siphon together with the drain port end 4a, when the level of the culture solution in the tank 11 drops to the level of the drain port end 4a, drainage stops. At this time, the floating member 13 is lowered and the opening 12 is open. Thereafter, the culture solution in the tank 11 increases, and the same operation as described above is repeated. At this time, the amount of culture solution discharged from the tank 11 is approximately proportional to the height (water head) of the siphon when the discharge starts, and the level when it stops is approximately at the end of the drain port. Since it is determined by the level of the outlet, the amount released per time is approximately the same, and the amount released per time can be changed by changing the level of the end of the drain port. In addition, although an example in which the intermittent water supply device according to the present invention is applied to a hydroponic cultivation device has been described above, it is easily understood that the intermittent water supply device according to the present invention can be applied in various ways other than the above. I can do it.
