The initial distance between the fixed contact and the movable contact is 5-10 mm.
Two ends of the salt bridge are respectively and fixedly connected with the anode tank and the cathode tank.
The working principle of the invention is as follows: when the welding position of the ash conveying pipeline and the medium pipeline is leaked, the flue gas enters the anode groove and the cathode groove from the damaged welding position, the copper sulfate powder and the zinc sulfate powder are dissolved by steam water in the flue gas, the salt bridge, the zinc column and the copper column form a battery, the zinc column is subjected to oxidation reaction, the copper column is subjected to reduction reaction, and the electromagnetic valve is electrified and opened; therefore, compressed gas in the air bag is blown out through the air blowing pipeline and pushes the fan blades to rotate, and the fan blades drive the rotating shaft and the gear to rotate; the gear further drives the rack and the sliding plate to move, and the sliding plate moves to enable the moving contact and the fixed contact to be in mutual contact so as to enable the electric heating wire to be electrified and heated; the electric heating wire enables the tin bar to melt the natural flow channel welding seam to carry out leakage repairing on the welding seam; meanwhile, the alarm lamp is automatically turned on after the positive electrode and the negative electrode of the battery are switched on, so that an operator is reminded of leakage, and the operator overhauls the leakage position and replaces the new battery after the machine is stopped, so that the next leakage is prevented.
The invention has the following beneficial effects: 1. the automatic leakage repairing of the welding seam is realized, and manual inspection is not needed for finding, so that automatic processing is performed at the initial stage of leakage occurrence, and loss caused by leakage is greatly reduced; the processing efficiency is improved; 2. the alarm lamp is automatically lighted after the leakage happens, and the operator is prompted to replace parts so as to prevent the leakage from happening next time.
