[0002] The core application of voltage and current in gas pipeline is a technology called "cathodic protection". Its only purpose is to prevent buried metal pipeline from being corroded (rusty). Basic principle: metal will have an electrochemical reaction (similar to a huge battery) in the soil, causing the metal to lose electrons (become ions), that is, be corroded. Cathodic protection applies an external current to force the pipeline to become a "cathode" (the side that gains electrons) in the circuit, thereby inhibiting the process of losing electrons and being corroded. The voltage detection of gas pipeline is through the test pile along the line, using reference electrode and high resistance multimeter to measure the potential of the pipeline to the soil, so as to evaluate whether the cathodic protection system is effective.

[0003] The existing multimeter is generally an independent body. When in use, the common operation mode is that the worker holds or fixes it in the required position.

[0030] It should be noted that: through the setting of the support assembly 2, in the subsequent use process, the staff can first place the support plate 21 on the arm, then wind the bandage 212, and make it adhere between the felt strips 211 through the magic tape, so as to realize the fixation of the support plate 21 and the arm, then the support frame 22 can be installed on the support plate 21 through the adsorption of the magnetic disc 221 and the chuck 24, so as to realize the support wearing of the high internal resistance multimeter 1 in the support frame 22, and thus in the use process, the staff does not need to manually hold or additionally fix the high internal resistance multimeter 1, so that the use flexibility and portability of the device can be improved.

[0031] In the embodiment of the utility model, please refer to Figures 1 to 6 One end of the support plate 21 is provided with a slot 213, the other end of the support plate 21 is provided with a plug hole 214, the inner wall of the slot 213 is in abutment with the outer wall of the detection pen in the high internal resistance multimeter 1, and the connector in the detection pen is inserted into the plug hole 214.

[0032] It should be noted that: through the setting of the slot 213, in the time interval process, when the detection pen needs to be placed, it can be inserted into the slot 213, and the end of the detection pen is shielded by the support plate 21, so that the probability of damage of the detection pen due to collision during use can be reduced.

[0033] Meanwhile, after completing the use of the device, the connector of the detection pen can be pulled out of the high internal resistance multimeter 1 and inserted into the plug hole 214, so that the protection of the connector can be realized.

[0034] In the embodiment of the utility model, please refer to Figures 1 to 6The top of the support plate 21 is provided with a fixedly connected mounting rack 23, one side of the mounting rack 23 is provided with a rotationally connected rotating rod 231, the other side of the mounting rack 23 is provided with a fixedly connected guide rod 232, the symmetrical link rods 233 are movably arranged between the rotating rod 231 and the guide rod 232, the inner wall of one end of the link rod 233 abuts against and is slidably connected with the outer wall of the guide rod 232, the inner wall of the other end of the link rod 233 is threadedly connected with the outer wall of the rotating rod 231, the thread directions of the thread structures on the two sides of the outer wall of the rotating rod 231 are opposite, the two link rods 233 are both provided with a fixedly connected blocking ring 234, and the top of the chuck 24 is fixedly provided with a blocking strip 241 for blocking the movement track of the blocking ring 234.

[0035] It should be noted that: since the thread directions of the thread structures for connecting the rotating rod 231 with the link rod 233 are opposite, the link rod 233 can be relatively or oppositely driven when the rotating rod 231 rotates, so that the link rod 233 can smoothly drive the blocking ring 234 to limit or release the limiting of the magnetic disc 221, and after the magnetic disc 221 is limited, the support frame 22 can be driven by the staff as needed in the later use, so that the internal high-resistance multimeter 1 is rotated, the angle of the high-resistance multimeter 1 can be adjusted, and therefore the flexibility of the staff operation can be further improved.

[0036] Meanwhile, the rotating rod 231 can be externally sleeved with a screw rod protection sleeve for protection, so that the probability of blockage of the rotating rod 231 to the driving of the link rod 233 due to the scattering of external dust particles and other substances on the thread in the later use can be reduced, and stable driving of the link rod 233 can be realized.

[0037] In the embodiment, when the blocking ring 234 is driven in the direction of the center of the chuck 24, the protruding blocking strip 241 can block and position the movement track of the blocking ring 234, so that the blocking ring 234 can be smoothly moved to the required position, the outer wall of the magnetic disc 221 located in the chuck 24 can be accurately shielded and limited, and the influence caused by the deviation of the position of the blocking ring 234 when the blocking ring 234 is driven can be reduced.

[0040] The working principle of the gas pipeline voltage detection device is as follows:

[0041] When using the device, the staff can first place the support plate 21 on the arm, then fix the support plate 21 and the arm by adhering between the binding band 212 and the felt strip 211, after fixing the support plate 21, the support frame 22 can be taken out, and the magnetic disc 221 at the bottom of the support frame 22 is placed in the chuck 24, at this time the magnetic disc 221 can be mutually adhered with the chuck 24 through the magnetic block;

[0042] Then the rotating rod 231 can be controlled to rotate, the rotating rotating rod 231 can drive the two side linkage rods 233 to move relative to each other through the thread structure with opposite thread directions on the two sides of the outer wall, the relative movement of the linkage rod 233 can drive the blocking ring 234 to move synchronously, until the blocking ring 234 moves above the side wall of the magnetic disc 221, the vertical limiting of the magnetic disc 221 can be realized, so that the phenomenon of the magnetic disc 221 falling out of the chuck 24 in the later use can be reduced, the stability of the connection between the chuck 24 and the magnetic disc 221 is improved, and the wearing of the high internal resistance multimeter 1 can be realized;

[0043] At this time, the staff can take out the test pen in the high internal resistance multimeter 1 from the slot 213, and insert the connecting line into the interface of the high internal resistance multimeter 1, then the test pen can be used to detect the voltage of the gas pipeline as needed, during the detection, the staff can move the support frame 22 as needed, so that the support frame 22 can rotate in the chuck 24 through the magnetic disc 221, the angle of the high internal resistance multimeter 1 in it can be adjusted, so that the staff can adjust the high internal resistance multimeter 1 to a comfortable angle for their own use;

[0044] And in the use process, the staff needs to perform additional hand operation, when the test pen is put down, the test pen can be inserted into the slot 213, so that the storage of the test pen can be realized, compared with directly placing the test pen on the ground, the probability of damage of the test head in the test pen due to wear can be reduced;

[0045] At the same time, in the use process, the air bag 3 protruding from the four corners of the support frame 22 can also absorb and buffer the force generated when the device bumps with the outside, so that the probability of damage caused by bumping in the later use process can be reduced.
