Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

A rain gauge for measuring different time periods is characterized in that it includes a casing 7, a rain storage device located on the upper part of the casing, a turntable 1 inside the casing, a motor 12 for driving the turntable 1 to rotate, and the motor 12 through a wire 13 connected to the controller 14, the measuring cylinder 3 on the turntable 1; the rain storage device includes a rain storage device 6, a baffle 16 located at the bottom 4 of the water storage pipe 5, and a drain pipe 17 from top to bottom.

A rotating shaft 8 is arranged below the center of the turntable 1 , a gear 9 is arranged on the rotating shaft 8 , and the motor 12 is used to drive the gear 9 to rotate so as to drive the turntable 1 to rotate.

A bottom end of the rotating shaft 8 below the turntable 1 is provided with a base 10 , and the base 10 is fixed on the bottom of the housing 7 by a fixing device 11 . When the rotating disk 1 and the measuring cylinder 3 rotated, the housing 7, the rain holding device and the base 10 were all fixed.

A graduated cylinder base 2 is arranged on the turntable 1, and a graduated cylinder 3 is placed on the graduated cylinder base 2.
