Claims

[Scope of Claim for Utility Model Registration] 1. A suction pipe and a suction bell are connected to the lower part of the float, and a motor-driven impeller that sucks in and discharges liquid through the suction pipe and the suction bell is installed at the upper part of the suction pipe, In a floating aerator in which a deflector is attached above the float so as to form a discharge flow path between the float and the upper surface of the float, a groove penetrating inside and outside is formed in a part of the flange surface of the suction pipe. A floating aerator characterized in that a drawer seat corresponding to a shaped power cable storage section is provided, and the power cable is fixed by sandwiching the groove-shaped drawer seat between the flange surfaces of a motor support ring. . 2. A suction pipe and a suction bell are connected to the lower part of the float, and a motor-driven impeller that sucks in and discharges liquid through the suction pipe and the suction bell is installed at the upper part of the suction pipe. In a floating aerator in which a deflector is attached to form a discharge flow path between the upper surface of the float,
A floating aerator, characterized in that a fastening seat for a mooring rope for mooring and fixing the aerator main body to the periphery of an installation tank is provided integrally with the float in a submerged part of the lower surface of the float of the main body.
