String magnesium alloy (aluminum alloy) sacrificial anode

First, according to parameters such as seawater resistivity, pipe length, surface resistance, design life, sacrificial anode performance, etc., design the amount of anode material in each pipe, the number of pieces, and the distance in the pipe. The prepared magnesium alloy (aluminum alloy) anode blocks are successively welded into a string with flat steel. The distance between magnesium alloy (aluminum alloy) anode blocks is the length of the flat steel, which is equal to the designed magnesium alloy (aluminum alloy) anode distance. Coat the back of each magnesium alloy (aluminum alloy) anode block with three layers of epoxy asphalt paint to make the current distribution more even. Put the magnesium alloy (aluminum alloy) anode string into the protected pipe with the back close to the pipe wall, and weld the flat steel at both ends to the pipe mouth. A suspension type string sacrificial anode group suitable for use in a wind turbine barrel, which is characterized in that it comprises a string type sacrificial anode group, a suspension ring, a cable, a stainless steel steel cable and a block sacrificial anode body, and the string type sacrificial anode group It consists of a block-shaped sacrificial anode body directly casted and connected to a stainless steel cable, and the cable connecting the block-shaped sacrificial anode body is attached to the stainless steel cable; the top of the string-type sacrificial anode group is connected to the The upper part of the protective wind turbine barrel is connected with the crossbeam, and the series sacrificial anode group is connected with the protected wind turbine barrel through a cable to form a cathodic protection system. This simplifies the installation work of the string sacrificial anode, only needs to be hung inside the wind turbine barrel, and does not require land field installation operations and underwater installation operations, which shortens the installation time and saves construction costs.
