In use, first, the insertion plate 5 to which the PH test paper is fixed is inserted into the inside of the side wall of the drum 41 at the time of rain. Then, the spring 42 is wound by inserting a wrench into the wrench insertion hole 71 a. The magnitude of the force can be selected according to the magnitude of the rainwater. The larger the rainwater, the more the number of turns of the rotation column 71, and the smaller the rainwater, the fewer the number of turns of the rotation column 71. Specifically, after a wrench is inserted into the wrench insertion hole 71a, the wrench is turned to rotate the rotation post 71, and the gear 72 rotates the engaged drum 41, so that the connected spiral spring 42 is contracted and tightened.
