The invention provides an inspection well cover achieving water drainage easily, and belongs to the field of inspection well covers. The problem that an existing inspection well cover needs to be overall opened for water drainage is solved. The inspection well cover achieving water drainage easily comprises an inspection well cover body and a cast iron seat matched with the inspection well cover body. The cast iron seat is provided with an annular seat ring. A plurality of supporting rods are connected between the circumference of the inspection well cover body and the inner circumference of the seat ring. One ends of the supporting rods are hinged to the inspection well cover body through first rotary shafts, and the other ends of the supporting rods are hinged to the seat ring through second rotary shafts. Containing grooves are formed in the seat ring, sliding grooves are formed in the walls of the containing grooves, and the two ends of the second rotary shafts are arranged on the sliding grooves. When the inspection well cover body is arranged on the cast iron seat in a matched manner, the second rotary shafts slide along the sliding grooves so that the supporting rods can be arranged in the containing grooves, the inspection well cover body is flush with the upper surface of the seat ring at this moment, one ends of the supporting rods can rotate along the first rotary shafts, the other ends of the supporting rods rotate along the second rotary shafts, the second rotary shafts slide in the sliding grooves, and the inspection well cover body is lifted. During water drainage and flood discharge, the inspection well cover body is lifted through the supporting rods, and a clearance between the inspection well cover body and the cast iron seat can be used for water drainage.
