Floating auxiliary anode installing and fixing device

The invention belongs to the technical field of nuclear power maintenance, and in particular relates to a floating auxiliary anode installing and fixing device. According to the embodiment of the invention, the entire floating auxiliary anode installing and fixing device is placed at the bottom end of a water body through a base. As the horizontal position of an auxiliary anode is lower than the horizontal position of the bottom end of a float bowl and the float bowl can move up and down relative to a water inlet drum along with the change of the liquid level in the water inlet drum, the auxiliary anode can always be below the liquid surface of the water body under the condition of the change of the water level of the water body, thus, the protection range of the auxiliary anode is expanded, and the cathodic protection can effectively protect equipment under the condition of the change of the water level of the water body. 本发明属于核电维修技术领域，具体涉及一种浮动式辅助阳极安装固定装置。本公开实施例通过底座将整个浮动式辅助阳极安装固定装置安放在水体的底端。由于辅助阳极的水平位置低于浮筒底端的
