Next, the tank 10 is installed so that the edge of the tank closer to the rain gutter 41 is closer than the length of the guide gutter.

Then, the lid 14 is rotated around the axis of the tank 10 so that the distance between the vertical gutter 41 and the rainwater supply port 15 corresponds to the length of the rainwater guide gutter 35. In this way, the guide gutter is fixed to the vertical gutter 41 and the rainwater supply port 15 by fitting it with an appropriate means, for example.

Next, one end of the hose is connected to the overflow pipe 17, and the lower end thereof faces the drainage mass or drainage groove. A water supply tap 18 is connected with a hose from the tap of the water supply as required.

When rainwater is supplied into the tank 10 through the rainwater guide trough 35, the water level in the tank 10 rises, and when it reaches the position of the overflow pipe 17, further rainwater overflows into the tank 10. No more water collects. The overflowed water is discharged to drainage mass, sewage, etc. through a continuous hose. When the rainwater is insufficient, tap water is supplied from the tap water supply port 18. When the water level reaches the required water level due to the supply of tap water, the float valve 19 stops the supply of tap water. The water level at which the float valve 19 closes is just below the overflow pipe.

In the embodiment including the device according to claim 4, since the tank 10, the lid 14 and the like are made of the above-mentioned materials, the tank 10 and the lid 14 are sufficiently resistant to wind and rain and changes in climate, and the discharge faucet 22, Since the valve 25 of the drain pipe 24 is also an engineering plastic molded product, its connection can be completely welded or adhered to the tank body, and there is no water leakage, and it can be attached to any of the joined rain member pipes. Comfortable and durable for long-term use.

Embodiment 1 The embodiment shown in FIGS. 1 and 2 is an embodiment including the invention described in all claims. The side wall 12 of the tank 10 is formed by a large-diameter cylinder made of polyvinyl chloride, which is an example of hard engineering plastic, and is for small household use. For example, the size is 50 cm in diameter and 70 cm in height. The bottom plate 11 and the side wall 12 had a thickness of 5 mm. The lid 14 is also made of the same material as the tank 10, and the rainwater supply port 15 has a diameter of 70.5 cm. As the crank-shaped rainwater guide gutter 35, the one having a circular cross-sectional shape and excluding the corner round connecting pipe 38 in FIG. 2 was used. Further, the frame 30 is formed by welding a steel material, and the tank 10 can be placed thereon. The water level pipe 23 and the drain pipe 24 provided were used.

Operation and Effect of Embodiment 1 The operation is the same as the operation of the invention described in each of the above claims. The difference is that since the water level pipe 23 is provided, the water level in the tank 10 can be known from the outside. Therefore, if the amount of stored water is insufficient, tap water is replenished. If mud or the like accumulates in the tank 10 after a long period of use, the valve 25 of the drain pipe 24 is opened to drain the mud from the tank and, if necessary, rinse with tap water.

Second Embodiment The only difference from the first embodiment is that the corner round connecting pipe 38 is connected to the upper end of the rainwater guide gutter 35. The upper half portion of the connecting pipe 38 is in the shape of a rectangular tube 38a, and is used by being fitted with a rectangular rain gutter 41. Since the lower half of the connecting pipe 38 is in the shape of a cylinder 38b, the rainwater guide trough 35 can be rotated in any direction at the joint portion of the elbow connecting pipe 37 and the rounded corner connecting pipe 38 with respect to the rain gutter 41. . Therefore, when the device of the present invention is installed, if the tank 10 and the gantry 30 are installed in accordance with the dimensions between the rain gutter 41 and the rainwater supply port 15, the tank 10 and the gantry 30 can be oriented in any direction. However, even if the stem 14 is rotated with respect to the tank 10, the rainwater guide gutter 35 can be installed without being twisted.

In the present invention, since the tank 10 and the lid 14 are both circular, the lid 14 is rotated with respect to the tank 10 so that the vertical rain gutter 41 and the rainwater supply port 15 to be installed are provided. The distance can be changed freely, and the length of the rainwater guide gutter 35 can be matched exactly.

At this time, since the upper end of the rainwater guide gutter 35 is a vertical gutter 41, and the lower end of the rainwater guide gutter 35 and the connection part of the rainwater supply port 15 are both rotatable about the axis line, the rainwater can be rotated. The guide gutter 35 can be easily installed without being twisted.

This device collects rainwater spring water, etc., and is used not only as water for trees, flowers and agriculture, but also for fire prevention in an emergency, and if the tank is kept clean, drinking water in an emergency is required. Even when used as a tank, it is within the scope of this invention.

If it is made large, it can also be used as a rainwater tank for office buildings, factories, etc., and it can also be connected to the drainage gutters of elevated roads or elevated railways. It can be used as a tank for watering.
