Embodiment 1
[0039] Example one, as Figure 1-Figure 7 As shown, the present invention provides a power-on protection device for the inner wall of a pipeline, including: a potentiostat 100, a reference electrode 200, a cathode line 300, a zero-cathode line 400 and a linear anode assembly 500; the potentiostat has a power output port, a detection port, cathode port and zero cathode port, the reference electrode 200 is connected with the detection port, the cathode line 300 is connected with the cathode port, and the zero cathode line 400 is connected with the zero cathode port;
[0040] The linear anode assembly 500 includes an anode cable 1 and a plurality of anode modules 2. The anode cable 1 is provided with a plurality of annular slits 11. The anode module 2 includes an inlaid conductive member 21, an anode tube 22 and an insulating tube 23. The inlaid conductive member 21 is arranged in the annular cutout 11 and is in contact and electrically connected with the core body 10 of the anod...
Embodiment 2
[0050] Embodiment 2, based on the above-mentioned embodiment of the energization protection device for the inner wall of the pipeline, its specific construction method includes:
[0051] Connect the cathode line and the zero cathode line to the pipeline to be protected, and insert the reference electrode into the pipeline to be protected; lay the anode cable on the inner wall of the pipeline to be protected, and fix the anode module on the inner wall of the pipeline to be protected superior.
[0052] Specifically, in actual construction, for buried pipelines, the cathode line and the zero-cathode line can be directly connected to the outer wall of the pipeline through the terminal, while the reference electrode is inserted into the pipeline through a hole seal. At the same time, it is also necessary to open a wiring hole on the pipe wall of the pipe, so as to allow the anode cable to pass through the wiring. The size of the wiring hole is larger than the size of the anode mod...
Embodiment 3
[0060] Embodiment 3, the present invention provides a processing method of a linear anode assembly, the linear anode assembly includes an anode cable and a plurality of anode modules, and the anode module includes an inlaid conductive member, an anode tube and an insulating tube; the specific processing method includes:
[0061] Step 1. On the whole anode cable, peel off the outer sheath of the anode cable at intervals to expose the core of the anode cable.
[0062] Step 2. Weld the inlaid conductive parts on the exposed core of the anode cable;
[0063] Step 3, sleeve the anode tube on the anode cable, so that the anode tube is sleeved on the outside of the inlaid conductive member, and by extruding the anode tube, the anode tube and the inlaid conductive member are in contact and conductively connected;
[0064] Step 4. Pour epoxy resin into both ends of the anode tube to complete waterproof sealing;
[0065] Step 5. An insulating tube is sleeved on the anode cable, so that...
