Detailed Description
The patent relates to an installation device and a construction method of an auxiliary anode in an impressed current cathodic protection system. As shown in fig. 1, in the concrete pouring stage of the gate plate guide groove, a customized glass fiber reinforced plastic shell 5 is pre-embedded in the concrete matrix 1, and then an auxiliary anode of the cathode protection system is installed in the glass fiber reinforced plastic shell 5. A rain-proof cabin 2 is built on a concrete matrix 1, and a host computer display 3 and a power system 4 are arranged in the rain-proof cabin 2. The glass fiber reinforced plastic shell 5 is hollow and three-dimensional L-shaped, as shown in figure 3, one surface of the glass fiber reinforced plastic shell is provided with a hanging box guide rail 12, and the bottom of the glass fiber reinforced plastic shell is provided with a sewage outlet 10. The auxiliary anode 9 is arranged in the auxiliary anode installation hanging box 8, the auxiliary anode installation hanging box 8 is arranged on a hanging box guide rail 12, and then is connected with the power system 4 through the power supply transmission cable 6. A grating plate 7 is arranged on the side, facing seawater, of the opening of the glass fiber reinforced plastic shell 5, the grating plate 7 is made of glass fiber reinforced plastic materials and is fixedly arranged on the concrete matrix 1, the grating plate 7 covers all openings on the lower portion of the glass fiber reinforced plastic shell 5, and only a sewage discharge outlet 10 is reserved, as shown in figure 2.
