[0049] The capacitor assembly includes a packaging structure 800, a cathode plate 801 and an anode plate 802. The cathode plate 801 and the anode plate 802 are connected to the sensor body through wires for electrical signals. The packaging structure 800 includes a fixed end and a telescopic end. The telescopic end is slidably connected to the inner wall of the fixed end. The telescopic end and the fixed end are filled with electrolyte. The cathode plate 801 and the anode plate 802 are respectively fixedly connected to the fixed end and the outer wall of the telescopic end of the packaging structure 800. When the telescopic end of the packaging structure 800 moves in the fixed end, the distance between the cathode plate 801 and the anode plate 802 can be adjusted. The spacing between the cathode plate 801 and the anode plate 802 is inversely proportional to the current passing through. The current passing through can be adjusted by changing the spacing between the cathode plate 801 and the anode plate 802.

[0050] See Figure 12-13The adjustment assembly includes an adjustment seat 700 and an adjustment screw 710. The adjustment seat 700 is fixedly connected to the top position of the anode plate 802. The inner walls on both sides of the adjustment cavity 204 are provided with a third slide groove. The two ends of the adjustment seat 700 are fixedly connected to the third slide plate 701.

When the first bevel gear 632 rotates, the second bevel gear 712 meshing therewith is driven to rotate, and then the adjusting seat 700 threadedly connected thereto is driven by the adjusting screw rod 710 to slide in the adjusting cavity 204 through the third slide 701, and then the anode plate 802 is pulled to increase the distance between the anode plate 802 and the cathode plate 801.

[0051] The working principle of the present invention is as follows: when it is necessary to measure the inner diameter of the pressure vessel body 100, the mounting block 201 on the detection plate 200 is fixed to the inner wall of the pressure vessel body 100 by bolts, and the plug-in block 330 on the side of the sliding seat 310 on the measuring rope 300 is inserted into the inner wall of the plug-in groove 402 on the movable fixed plate 400, the measuring rope 300 is pulled out from the sliding seat 310 and fixed to the inner wall of the pressure vessel body 100, and the protective film 301 is attached to the inner wall of the pressure vessel body 100 and wraps the measuring rope 300, and then the other end of the measuring rope 300 is inserted into the plug-in groove 402 on the fixable fixed plate 400 for fixing, and the inner diameter of the pressure vessel body 100 can be calculated according to the length of the pulled-out measuring rope 300 of the measuring instrument body 304 plus the length of the contact surface of the detection plate 200 with the pressure vessel body 100, and then the mounting plate 302 is installed in the mounting groove 202 by bolts and fixed for sealing;

[0052] When the measuring rope 300 is inserted into the insertion groove 402, the measuring rope 300 is fixed to the inner wall of the pressure vessel body 100 and is in a tensioned state. The measuring rope 300 can then pull the pull block 337 on the sliding plate 335 to squeeze and expand the iron plate 338, and the iron plate 338 can drive the limiting slider 333 and the insertion rod 334 to move and insert them into the insertion cavity 404 for fixation. When disassembly is required, the measuring rope 300 can be loosened to reset the iron plate 338, driving the insertion rod 334 to move out of the insertion cavity 404 and release the installation.

[0053] When the plug-in block 330 on the fixed rod 320 is inserted into the plug-in slot 402, and the plug-in rod 334 is inserted into the plug-in cavity 404, the locking block 412 can be squeezed to drive the locking block 412 to move back into the sliding rod 410, thereby releasing the fixation of the fixed plate 400 on the sliding rod 410, and the fixed plate 400 can slide along the sliding rod 410.

[0054] When the inner wall of the pressure vessel body 100 is deformed, the measuring rope 300 can be moved synchronously with the deformation of the pressure vessel body 100. The movement of the measuring rope 300 can drive the extension rod 311 to slide in the sliding seat 310 by pulling the measuring rope 300, and then drive the plug seat 401 and the fixed plate 400 to move. The movement of the fixed plate 400 can drive the first transmission rod 510 and the first piston plate 511 to slide in the first water storage chamber 500 through the second slide plate 501, and squeeze the aqueous solution to the second water storage chamber 502 to squeeze the second piston plate 520. The second piston plate 520 can drive the gear bar 530 to move through the second transmission rod 521, and the gear bar 530 can be driven by the movement The gear ring 610 rotates, and the gear ring 610 drives the second transmission gear 630 to rotate through the first transmission gear 620. The second transmission gear 630 drives the second bevel gear 712 on the meshing first bevel gear 632 to rotate through the transmission shaft 631 and the first bevel gear 632. Then, the adjusting screw 710 is rotated to drive the adjusting screw 710 threaded thereon to move, and then the packaging structure 800 is driven to expand and contract and the anode plate 802 is driven to move. The current passing through can be changed by changing the distance between the cathode plate 801 and the anode plate 802. The sensor body can process the change in current and transmit it to the user's mobile phone. The user can promptly know that the inner wall of the pressure vessel body 100 is deformed and perform maintenance.

[0055] When the present invention is used, the inner diameter of the pressure vessel body 100 can be calculated by setting the detection plate 200 and the measuring rope 300 through the length of the measuring rope 300 and the length of the side where the detection plate 200 is in contact with the pressure vessel body 100. The inner diameter is detected and transmitted to the user based on the change in current generated by the change in the distance between the cathode plate 801 and the anode plate 802. The user can know the deformation of the inner diameter of the pressure vessel body 100 in time and perform maintenance to avoid damage to the pressure vessel body 100 due to uneven force.

[0056] By setting up the first expansion component, the displacement transmitted from the fixed plate 400 to the gear bar 530 can be increased due to the difference in inner diameters of the first water storage chamber 500 and the second water storage chamber 502, thereby increasing the displacement of the anode plate 802, thereby avoiding the displacement being too small to cause the current change to be unclear, thereby affecting the sensitivity of the deformation monitoring of the pressure vessel body 100.

[0057] By setting up the second expansion component, the number of rotations of the second transmission gear 630 can be increased through the transmission of the first transmission gear 620 of the gear ring 610, which can further increase the displacement at the anode plate 802 and improve the sensitivity of deformation monitoring of the pressure vessel body 100.

[0058] By setting the sliding rod 410 and the locking block 412, the movement of the fixed plate 400 can be guided by the sliding of the sliding rod 410, and the sliding rod 410 can be pre-fixed by the locking block 412, and then the sliding fixed plate 400 can be pre-fixed, so as to avoid excessive tension in the measuring rope 300 during installation, which may cause the position of the fixed plate 400 to change and affect the accuracy of the measurement of the inner diameter of the pressure vessel body 100.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
