The normal water level of the steam drum is a necessary condition for ensuring the safe operation of the boiler and the steam turbine, if the monitoring and adjustment are not timely, the safe and stable operation of the unit is influenced, the deterioration of the quality of water vapor and even accidents are caused by overhigh and overlow water levels, the economical efficiency of the unit is influenced, and the safe operation of the unit is greatly threatened.
The steam drum water level electrode is in a high-temperature high-pressure environment and a severe environment surrounded by steam and water all the year round, and is very easy to be corroded and damaged, so that the steam drum water level electrode needs to be dismounted and maintained all the year round, and once the electrode is corroded seriously, great difficulty is brought to dismounting work. In the existing work of disassembling the water level electrode of the steam drum, a spanner is adopted to rotate a large nut on the electrode, and the electrode is pulled out from a measuring position by clamping the shell of the electrode base. This way of disassembly has two major drawbacks: firstly, the electrodes are arranged tightly, the tool is not unfolded, and other peripheral electrodes are easily damaged in the disassembling process; secondly, the force points are too concentrated, only the lead screw of the electrode at the minimum position is stressed, once the electrode is corroded seriously, the lead screw of the electrode or the screw thread of the detachable nut can be damaged, the nut and the electrode can not be taken out, even the electrode is twisted off, the electrode can not be taken out if the electrode is broken, a worker can only adopt the operation of fire, the electrode base is heated by fire welding, the electrode base is thermally expanded, the electrode residual part can be taken out, and if the electrode base can not be taken out, the electrode base needs to be cut off and then taken out. The work has the risks of personal injury and equipment damage, the work difficulty is high, and meanwhile, the work efficiency is very low.
Disclosure of Invention
The utility model aims to overcome the defects in the prior art and provide a rapid and safe electrode disassembling professional tool.
The technical scheme of the utility model is as follows: the utility model provides a specialized tool is dismantled to electrode, characteristics are, including mounting and connecting piece, are equipped with central cavity on the mounting, and the connecting piece passes through central cavity activity plug bush in the mounting, are equipped with horizontal guide slot in the mounting bottom, and the internal diameter of horizontal guide slot is greater than the internal diameter of central cavity, is equipped with inside electrode connection screw thread in the bottom of connecting piece, is equipped with the external screw thread at the upper end outer wall of connecting piece, is equipped with tensile nut corresponding to external screw thread department.
Furthermore, an inner groove is formed in the inner wall of the central cavity of the fixing piece, a protrusion is arranged on the outer wall of the bottom end of the connecting piece, and the protrusion corresponds to the inner groove.
The main problems in the disassembly work of the water level electrode of the steam drum are that the electrode is tightly arranged, so that a tool cannot be unfolded, the electrode is easily damaged when the electrode is disassembled and concentrated. Aiming at the problems, the innovative electrode disassembling tool specially designs a combined structure of the fixing piece and the connecting piece in a sleeved mode, so that workers can complete electrode disassembling work in a narrow space, the electrode disassembling tool is simple and convenient to operate, and the electrode is effectively protected in the operation process.
The technical scheme of the utility model has four characteristics: the electrode assembly is characterized in that internal threads at the bottom of the connecting piece can be tightly combined with external threads of an electrode, so that the stress area during disassembly is increased, and the electrode is protected; the protection shell of the electrode is embedded into the horizontal guide groove of the fixing piece, so that the functions of fixing the electrode and balancing the utilization force are achieved; thirdly, according to actual field measurement, the length of the fixing piece is set to be proper, an electrode dense area is avoided, operation is convenient, and other electrodes are protected from being damaged; and fourthly, the protrusion of the connecting piece is flexibly embedded with the inner groove of the fixing piece, and the nut is stretched by rotating to obtain a horizontal tensile force, so that the electrode is uniformly stressed and is safely pulled out of the measuring cylinder.
Compared with the prior art, the utility model has reasonable structural design, small volume, safe and simple operation and can greatly improve the working efficiency.
The present invention will be explained in detail below with reference to the drawings and examples.

FIG. 2-a cross-sectional view of FIG. 1.
FIG. 3 is a schematic view of the structure of the connector of the present invention.
FIG. 4-the working principle of the utility model refers to the figure.
The drawings illustrate:
the electrode comprises a fixing piece, 2 horizontal guide grooves, 3 central cavities, 4 connecting pieces, 5 stretching nuts, 6 bulges, 7 electrode connecting screw threads, 8 electrodes, 9 external threads, 10 inner grooves, 11 wrench grooves and 12 electrode bases.
Detailed Description
Referring to fig. 1 to 4, a special tool for disassembling an electrode is composed of a fixing member 1 and a connecting member 4; the center of the fixed part 1 is provided with a central cavity 3, two sides of the inner wall of the central cavity 3 are symmetrically provided with two inner grooves 10, the bottom end of the fixed part 1 is provided with a horizontal guide groove 2, the inner diameter of the horizontal guide groove 2 is larger than that of the central cavity 3, namely, the joint of the horizontal guide groove 2 and the central cavity 3 is step-shaped; the connecting piece 4 is movably inserted and sleeved in the fixing piece 1 through the central cavity 3, two bulges 6 are symmetrically arranged on two sides of the outer wall of the bottom end of the connecting piece 4, the two bulges 6 correspond to two inner grooves 10 on the inner wall of the central cavity 3 of the fixing piece 1, an inward electrode connecting screw thread 7 is arranged in the center of the bottom end of the connecting piece 4, an external thread 9 is arranged on the outer wall of the upper end of the connecting piece 4, and a stretching nut 5 is arranged at a position corresponding to the external thread 9; in addition, for the convenience of force application, a wrench groove 11 is also arranged on the outer wall of the fixing member 1.
