The latch is released, the catch ring 41 is rotatably fixed to the support bracket 47 fixed to the drain 10.

As will be apparent to those skilled in the art, the weight of the weight 60 has a weight more than enough to be caught in the state shown in Figure 1 by lifting the empty reservoir 20 as shown in Figure 6, buoy 30 The water should not interfere with the conduction of the cold reservoir 20 to the extent that it is lifted. That is, the buoy 30 should not be heavier than the weight of the cold reservoir 20 so that the water is lifted.

≪ Example 1 >

In the embodiment of FIG. 2, the main distribution tank 11 has 19 drain holes 15a at the same height and has one guide hole 16a having the same area and the same height as the drain hole 15a. Only 1/20 of them are sent to the sub-distribution tank 12.

The first sub distribution tank 12a has four drain holes 15b formed at the same height and formed on both sides and lower than the drain holes 15a of the main distribution tank 11, and has the same area and the same height as the drain holes 15b. Since it has one induction hole 16b having, only one fifth of the incoming water is sent to the second sub distribution tank 12.

The second sub distribution tank 12b has four drain holes 15c at the same height, formed on both sides and lower than the drain holes 15b of the first sub distribution tank 12a, and has the same area as the drain hole 15c. Since one guide hole 16c has the same height, only one fifth of the incoming water is sent to the reservoir 20.

Therefore, only 1 / (20 * 5 * 5) = 1/500 of the water flowing into the feed pipe is sent to the reservoir 20 and the remaining 499/500 goes directly to the water tank.

When the capacity of the reservoir 20 became 2 L, the buoy 30 was supposed to release the catch 40. The one-way rotation power transmission unit 110 has a shape in which power is transmitted to the operating plate 115 when the second driving shaft 81 rotates clockwise as shown in FIG. 4.

Example 1 Action

If 24 tonnes of water (2000 liters, roughly equivalent to the usage of a rural village in the mountains) are sent to the water tank for 24 hours a day, 15 million of them are sent to the reservoir 20.

The buoy 30 of the reservoir 20 raises the upper end of the connecting rod 32a when 2 L of water is filled in the reservoir 20, and accordingly, the lower end of the connecting rod 32a is lowered and the operating lever 32 accordingly. The top of the rises and lifts the extension rod 44 connected to the catch ring (41). The catch of the catching ring 41 is released and the gripping state of the catching bar 23 is released so that the reservoir 20 rotates counterclockwise (based on FIG. 1) by gravity.

Therefore, while the reservoir 20 is in the state as shown in FIG. 6 in the state of FIG. 1, the connection line 50 rotates the pulley 72 in a counterclockwise direction (reference to FIG. 1), and drives the first drive shaft 71. The gear 73 rotates in the same direction (counterclockwise direction), and the first driven gear 82 rotates clockwise.

One-way rotational power transmission unit 110 of the form as shown in Figure 4 rotates the third drive shaft 91 of the operating plate 115 and the tube-driven pump 250 by the clockwise rotational force of the second drive shaft 81 to the chemicals. Drop into water tank (1).

When water in the reservoir 20 is completely poured into the water tank 1 in the state in which the reservoir 20 is completely inverted, the weight 60 pulls the connecting line 50 so that the reservoir 20 is caught as shown in FIG. 1. Return As will be apparent to those skilled in the art, the weight of the weight 60 has a weight more than enough to be caught in the state shown in Figure 1 by lifting the empty reservoir 20 as shown in Figure 6, buoy 30 The water should not interfere with the conduction of the cold reservoir 20 to the extent that it is lifted. That is, the buoy 30 should not be heavier than the weight of the cold reservoir 20 so that the water is lifted.

In this way, the device of Example 1 is to supply the disinfectant to the water tank 1 twice a day.
