, And slowly lower the cylindrical body 2 to the water surface 17.

In the above case, the rope 8 having the stoppers 7 and 7a attached to its tip is put into the underwater 17a of a river with the stoppers 7 and 7a separated from the cylinder 2 by 1 meter or more. When the cylinder 2 is put into the underwater 17a of the river, the front opening 2a is thrown toward the upstream of the river, in front of the cylinder 2, that is, as shown by an arrow d.

Then, the river water sampling devices 1 to 1b of the present invention which are put into the river sink into the water by the action of the horizontal wings 4 and 4a fixed to the outer peripheral surface of the cylindrical body 2. That is, the pressure due to the flowing water of the river is applied to the upper surfaces 4f and 4g of the horizontal wings 4 and 4a, and the force moves the cylinder 2 vertically downward. The sinking degree of the river water sampling devices 1 to 1b differs depending on the magnitude of the pressure of the flowing water.

In order to sink the cylinder 2 deeper, the cylinder 2
It is necessary to increase the force applied to the upper surfaces of the horizontal wings 4 and 4a. For this purpose, the angle at which the river water sampling devices 1 to 1b of the present invention are thrown into the river is changed. If the throwing angle is large, the force applied to the horizontal wings 4 and 4a increases, so that the cylinder 2 can be sunk in a deep place.

When the river water sampling devices 1 to 1b of the present invention reach a predetermined position of the flowing water of the river, the ropes 8 and 8a are pulled to bring the plugs 7 and 7a into close contact with the rear opening 2b of the cylindrical body 2. As a result, the flowing water flowing through the hollow interior of the cylindrical body 2 is stopped, and can be stored inside the cylindrical body 2.
River water sampling device 1
River water can be collected at ~ 1b.
