[0003] However, when measuring the inner diameter of a pressure vessel, it is usually necessary to rely on a detection instrument. However, there are some problems with existing detection instruments during use. When a pressure vessel is in use, its inner wall is prone to deformation due to the pressure of the stored substance. Unfortunately, existing detection instruments cannot monitor this deformation. Therefore, users cannot timely know the deformation situation of the pressure vessel, and thus cannot timely perform necessary maintenance, which may lead to uneven stress on the inner wall of the pressure vessel and ultimately cause damage. Therefore, the present invention provides an on-line inner diameter detector for a pressure vessel to solve the above-mentioned problems. Summary of the Invention

Specific embodiments

[0030] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Please refer to Figure 1, in the embodiment of the present invention, an on-line inner diameter detector for a pressure vessel includes a pressure vessel body 100. A bearing seat 103 for support is installed at the bottom of the pressure vessel body 100. A feed inlet 101 communicating with the pressure vessel body 100 is installed on one side of the top of the pressure vessel body 100. A plurality of linearly arranged discharge outlets 104 communicating with the pressure vessel body 100 are installed at the bottom of the pressure vessel body 100. A tank door panel 102 for opening and closing is provided at the middle position of the outer wall of the pressure vessel body 100. Valves for controlling opening and closing are installed on both the feed inlet 101 and the discharge outlets 104. When feeding and discharging are required, feeding and discharging can be carried out by opening and closing the valves of the feed inlet 101 and the discharge outlets 104 to store the material, and the inside of the pressure vessel body 100 can be cleaned by opening and closing the tank door panel 102; Refer to Figure 2 , a measuring component for measuring the inner diameter of the pressure vessel body 100 is installed on the inner wall of the pressure vessel body 100. The measuring component includes a detection plate 200 installed on one side of the inner wall of the pressure vessel body 100 and a measuring rope 300 linearly arranged and installed in the detection plate 200 and circumferentially fixed on the inner wall of the pressure vessel body 100. Installation blocks 201 are installed at both ends of the outer walls on both sides of the detection plate 200. The installation blocks 201 are fixedly connected to the inner wall of the pressure vessel body 100 by bolts. When the detection plate 200 needs to be fixed, the installation blocks 201 can be fixed on the inner wall of the pressure vessel body 100 by bolts, and then the detection plate 200 can be installed in the inner wall of the pressure vessel body 100. A plurality of linearly arranged protective films 301 are fixedly connected to the outer wall of the detection plate 200. The protective films 301 are made of flexible materials and are fixedly connected to the inner wall of the pressure vessel body 100. The measuring rope 300 is wrapped inside the protective films 301 and is circumferentially fixed on the inner wall of the pressure vessel body 100. Thus, the inner wall of the pressure vessel body 100 can be measured according to the length of the measuring rope 300. The design of the protective films 301 can protect the measuring rope 300 from being eroded by the substances stored in the pressure vessel body 100. Moreover, the protective films 301 can be extruded by the pressure of the substances stored in the pressure vessel body 100, and the extrusion of the protective films 301 on the measuring rope 300 can improve the tightness of the fit between the measuring rope 300 and the inner wall of the pressure vessel body 100; Refer to Figure 3-4, connection components for plugging and fixing are installed at both ends of the measuring rope 300. A plurality of linearly arranged chambers are provided at both ends of the detection plate 200. The chambers on the side of the detection plate 200 close to the inner wall of the pressure vessel body 100 are installation chambers 203 for cooperating with the installation of the connection components, and the chambers on the other side of the detection plate 200 are adjustment chambers 204 for adjustment. Installation components for cooperating with the fixing of the connection components are installed at both ends of the inner wall of the installation chamber 203 on the detection plate 200. One of the installation components is slidably connected to the inner wall of the other installation component.

The current on the capacitance component is monitored through the receiving module, processed through the processing module, and the signal is transmitted to the user's mobile phone through the communication module.

[0033] An adjustment component for adjusting the capacitance component is installed at the bottom of the second amplification component. Specifically, when the inner diameter of the pressure vessel body 100 deforms due to the extrusion of the internal substance, the measuring rope 300 fixed on the inner wall of the pressure vessel body 100 can change with the deformation of the pressure vessel body 100 at this time, and the installation component can be pulled to move through the connection component on it. The movement of the installation component is amplified by the first amplification component and the second amplification component, and the capacitance component is adjusted through the adjustment component. The current on it changes, and the signal can be received, processed, and transmitted to the user's mobile phone through the sensor body, and the user can know that the inner diameter of the pressure vessel body 100 has changed.

[0034] Refer to Figure 4-5, the connecting component includes a mounting plate 302, a sliding seat 310, a fixing rod 320 and a plugging block 330.

A measuring instrument body 304 for measuring the length of the measuring rope 300 is installed at the mounting plate 302 and the lining plate 303. The measuring instrument body 304 is electrically connected to the sensor body. Specifically, due to the design of the sliding seat 310 and the fixing rod 320, the plugging block 330 on one side of the fixing rod 320 can be fixed through the fixing rod 320, and the other plugging block 330 can move along with the extension rod 311 sliding in the sliding seat 310, and the measuring rope 300 passing through the mounting plate 302 is measured by the measuring instrument body 304.

[0035] More specifically, refer to Figure 3-4 , mounting grooves 202 are provided at both ends of the installation cavity 203 where the detection plate 200 is located. The mounting grooves 202 are adapted to the mounting plate 302, and an inner cavity adapted to the lining plate 303 is arranged on one side of the mounting groove 202 close to the installation cavity 203. Specifically, after the plugging block 330 is installed, at this time, the lining plate 303 on the mounting plate 302 is inserted into the inner cavity. At this time, the installation cavity 203 is sealed by squeezing the sealing ring, and the mounting plate 302 is installed on the inner wall of the mounting groove 202 through bolts.

Raised portions are fixedly connected to both outer walls of the limiting sliding block 333. The raised portions are slidably connected to the inner wall of the limiting sliding cavity. By sliding the limiting sliding block 333 and the raised portions thereon in the limiting sliding grooves 332 and the limiting sliding cavities, the movement of the plugging rod 334 can be limited. A plurality of circumferentially arranged first sliding holes are formed in the measuring rope 300. The plugging rod 334 is slidably connected to the inner wall of the first sliding hole.

The iron plate 338 is fixedly connected to the opposite wall surfaces of the sliding plate 335 and the limiting sliding block 333. The iron plate 338 is made of memory metal material. When the measuring rope 300 is fixed to the inner wall of the pressure vessel body 100, at this time the measuring rope 300 can be tightened. The measuring rope 300 can pull the pulling block 337 and drive the first sliding plate 336 to slide in the measuring rope 300. At this time, the sliding plate 335 and the pulling block 337 can be pulled to move upward. When the sliding plate 335 moves upward, the iron plate 338 can be extruded. When the iron plate 338 is extruded, it can deform and expand outward, and then drive the limiting sliding block 333 to slide in the limiting sliding groove 332. The limiting sliding block 333 can drive the plugging rod 334 to move synchronously and extend through the first sliding hole on the plugging block 330 to the outside. When the plugging block 330 is not tightened, it can be reset under the deformation of the iron plate 338 at this time.

[0037] Refer to Figure 7-8, the installation components include a fixing plate 400 and a socket 401. One of the fixing plates 400 is fixedly connected to the inner wall of the installation cavity 203 on the detection plate 200, and the other fixing plate 400 is slidably connected to the inner wall of the detection plate 200.

A plurality of socket cavities 404 arranged in a circular pattern are provided on the inner wall perpendicular to the axis of the socket groove 402. The socket rod 334 is adapted to the socket cavity 404. When fixation is required, at this time, the socket block 330 is inserted into the inner wall of the socket groove 402, and the tension of the measuring rope 300 drives the socket rod 334 to move out of the first sliding hole and be inserted and fixed on the inner wall of the socket cavity 404, so that the measuring rope 300 can be fixed.

[0038] Refer to Figure 8-9 , a plurality of sliding rods 410 arranged in a circular pattern are fixedly connected to the outer wall of one of the fixing plates 400.

The magnetic poles on the opposite wall surfaces of the two magnets 422 are the same. When the insertion rod 334 is inserted into the insertion cavity 404, the elastic ring 420 can be driven to deform and fit on the outer wall of the insertion rod 334 by squeezing the elastic ring 420, so as to increase the friction force with the insertion rod 334 and improve the connection stability of the insertion rod 334. And when the insertion rod 334 shakes, at this time, the elastic ring 420 can be further squeezed to deform and enter the buffer cavity 421 to squeeze the magnets 422, driving the two magnets 422 to approach, and the stress of the squeeze can be buffered by the magnetic force, further improving the stability of the insertion rod 334.

When the fixing plate 400 moves, the second sliding plate 501 can be driven to slide in the second sliding groove, and the first piston plate 511 can be driven to move in the first water storage cavity 500 to push the aqueous solution through the first transmission rod 510. The aqueous solution can enter the second water storage cavity 502 to push the second piston plate 520, and then drive the gear bar 530 to move through the second transmission rod 521. And the inner diameter of the second water storage cavity 502 is smaller than that of the first water storage cavity 500. Therefore, when the fixing plate 400 moves, the moving distance of the gear bar 530 can be increased.

[0041] Refer to Figure 12, the second expansion component includes a gear ring 610, a first transmission gear 620, and a second transmission gear 630. A fixing block 600 is fixedly connected to the inner wall of the adjustment cavity 204 on the detection plate 200 at the bottom of the first water storage cavity 500. The gear ring 610 is rotatably connected to the outer wall of the fixing block 600. The gear ring 610 is in an annular structure, and gear grooves are provided on both the inner ring and the outer ring of the gear ring 610. The gear bar 530 meshes with the outer wall of the gear groove on the outer ring of the gear ring 610. The first transmission gear 620 is rotatably connected to the outer wall of the fixing block 600 and is located at both ends of the inner ring of the gear ring 610. The first transmission gear 620 meshes with the inner wall of the gear groove on the inner ring of the gear ring 610. The second transmission gear 630 is rotatably connected to the outer wall of the fixing block 600 at the axial position of the gear ring 610. The second transmission gear 630 meshes with the outer wall of the first transmission gear 620, and a transmission shaft 631 is fixedly connected to the axial position of the second transmission gear 630. A first bevel gear 632 is fixedly connected to the outer wall of the transmission shaft 631. When the gear bar 530 moves, it can drive the gear ring 610 meshing with it to rotate. The gear ring 610 can drive the first transmission gear 620 to rotate through the gear groove on the inner ring. The first transmission gear 620 can drive the second transmission gear 630 meshing with it to rotate. The second transmission gear 630 can drive the transmission shaft 631 and the first bevel gear 632 on it to rotate synchronously. And this transmission method can increase the number of rotations of the second transmission gear 630, and then further expand the movement of the fixing plate 400.

[0042] The capacitor component includes a packaging structure 800, a cathode plate 801, and an anode plate 802. The cathode plate 801 and the anode plate 802 are electrically connected to the sensor body through wires. 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 outer walls of the fixed end and 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 distance between the cathode plate 801 and the anode plate 802 is inversely proportional to the passing current. Then, the passing current can be adjusted by changing the distance between the cathode plate 801 and the anode plate 802.

[0043] Refer to Figure 12-13, the adjusting assembly includes an adjusting base 700 and an adjusting screw rod 710. The adjusting base 700 is fixedly connected to the top position of the anode plate 802. Third chutes are provided on both inner walls of the adjusting cavity 204.

When the first bevel gear 632 rotates, it can drive the second bevel gear 712 meshing with it to rotate, and then drive the adjusting base 700 threadedly connected thereto to slide in the adjusting cavity 204 through the third sliding plates 701, thereby pulling the anode plate 802 and increasing the distance between the anode plate 802 and the cathode plate 801.

[0044] The working principle of the present invention is as follows: When the inner diameter of the pressure vessel body 100 needs to be measured, at this time, the mounting block 201 on the detection plate 200 is fixed to the inner wall of the pressure vessel body 100 by bolts. The insertion block 330 on one side of the sliding seat 310 on the measuring rope 300 is inserted into the inner wall of the insertion slot 402 on the moving fixing 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. Then the other end of the measuring rope 300 is inserted into the insertion slot 402 on the fixable fixing plate 400 for fixation. Then, according to the measuring instrument body 304, the length of the pulled-out measuring rope 300 plus the length of the joint surface of the detection plate 200 with the pressure vessel body 100 can be used to calculate the inner diameter of the pressure vessel body 100. Then, the mounting plate 302 is installed in the mounting slot 202 by bolts for fixation and sealing; When the measuring rope 300 is inserted into the insertion slot 402, at this time, the measuring rope 300 is fixed to the inner wall of the pressure vessel body 100 and is in a tensioned state. It can pull the pull block 337 on the sliding disk 335 through the measuring rope 300 to expand the iron plate 338, and drive the limit slider 333 and the insertion rod 334 to move and insert into the insertion cavity 404 for fixation through the iron plate 338, thus completing the fixation. When disassembly is required, just by relaxing the measuring rope 300, the reset of the iron plate 338 can be used to drive the insertion rod 334 to move out of the insertion cavity 404 to release the installation; When the insertion block 330 on the fixing rod 320 is inserted into the insertion slot 402, and at this time when the insertion rod 334 is inserted into the insertion cavity 404, the locking block 412 can be driven to move back into the sliding rod 410 by squeezing the locking block 412, and the fixing of the fixing plate 400 on the sliding rod 410 can be released, and the fixing plate 400 can slide through the sliding rod 410; When the inner wall of the pressure vessel body 100 deforms, at this time the measuring rope 300 can move synchronously with the deformation of the pressure vessel body 100. When the measuring rope 300 moves, the elongation rod 311 can be driven to slide in the sliding seat 310 by pulling the measuring rope 300, and then the insertion seat 401 and the fixing plate 400 can be driven to move. When the fixing plate 400 moves, the first transmission rod 510 and the first piston plate 511 can be driven to slide in the first water storage cavity 500 by the second sliding plate 501, and the aqueous solution can be squeezed to the second water storage cavity 502 to squeeze the second piston plate 520. The second piston plate 520 can drive the gear rack 530 to move through the second transmission rod 521. The gear rack 530 can drive the gear ring 610 to rotate by moving. 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 rod 710 rotates to drive the adjusting screw rod 710 connected to it by thread to move, and then drives the encapsulation structure 800 to expand and contract and drives the anode plate 802 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 be processed through the change of the current and transmitted to the user's mobile phone, and the user can timely know that the inner wall of the pressure vessel body 100 deforms and carry out maintenance.

[0045] When the present invention is in use, through the provided detection plate 200 and the measuring rope 300, the inner diameter of the pressure vessel body 100 can be calculated through the length of the measuring rope 300 and the length of the side of the detection plate 200 that fits the pressure vessel body 100. And the inner diameter is detected according to the change of the current generated by the change of the distance between the cathode plate 801 and the anode plate 802 and transmitted to the user. The user can timely know the deformation of the inner diameter of the pressure vessel body 100 and carry out maintenance to avoid damage to the pressure vessel body 100 caused by uneven force.

[0046] Through the provided first expansion component, the displacement amount conducted by the fixing plate 400 to the gear rack 530 can be increased through the different inner diameters of the first water storage cavity 500 and the second water storage cavity 502, and then the displacement amount at the anode plate 802 can be increased, avoiding the displacement being too small resulting in an unclear current change, and further affecting the sensitivity of the deformation monitoring of the pressure vessel body 100.

[0047] Through the provided 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, and then the displacement at the anode plate 802 can be further increased, improving the sensitivity of the deformation monitoring of the pressure vessel body 100.

[0048] Through the provided sliding rod 410 and locking block 412, the movement of the fixing 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 fixing plate 400 can be pre-fixed, avoiding the position change of the fixing plate 400 caused by excessive tension during the installation of the measuring rope 300, which affects the accuracy of the inner diameter measurement of the pressure vessel body 100.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
