Description

Technical Field

[0001] The present invention relates to the field of transmitter preparation, and in particular to a transmitter preparation detection system and a detection method. Background Art

[0002] Transmitters operate based on the principle of negative feedback and primarily consist of a measuring section, an amplifier, and a feedback section. Common transmitters include standard pressure transmitters, differential pressure transmitters, single / double flange transmitters, and insert flange transmitters. In addition to measuring pressure, pressure transmitters can also measure liquid level within equipment, making pre-shipment pressure testing of pressure transmitters particularly important.

[0003] In the prior art, when performing pressure detection on a pressure transmitter, the detection end of the pressure transmitter is usually installed on the pressure detection position by threaded engagement, and then the connecting component on the power supply device is connected to the corresponding interface on the upper end of the pressure transmitter. The pressure transmitter is then detected by cooperating with the pressure detection device connected to the detection position and the power supply device.

[0004] However, in the process of using the above-mentioned existing technology to detect pressure on the pressure transmitter, there are still the following shortcomings:

[0005] 1. The process of installing the pressure transmitter at the detection position and the process of removing the pressure transmitter from the detection position both require rotating the pressure transmitter, which is cumbersome and reduces the efficiency of pressure detection of the pressure transmitter.

[0006] 2. The specifications of the interface connected to the pressure transmitter on the existing pressure detection position are fixed, so only pressure transmitters of one specification can be detected. However, the interface of the pressure transmitter detection end has different diameter specifications, so the applicability of the pressure detection position with a fixed interface diameter specification is low.

[0050] The following will be described in detail in combination with the accompanying drawings Figures 1-15 The embodiments of the present application are described in detail, but the present application can be implemented in various different ways limited and covered by the claims.

[0051] The embodiment of the present application discloses a transmitter preparation detection system and detection method, which is mainly applied to the process of detecting the transmitter. In terms of technical effect, the transmitter can be quickly connected with the pressure testing device, and the transmitter can be quickly removed, thereby improving the efficiency of detecting the transmitter. Especially in the process of connecting the transmitter, it can also be applied to different diameter transmitters, thereby improving the applicability of the present application.

[0052] Embodiment one:

[0053] Refer toFigures 1 to 4 As shown in the figure, the transmitter preparation detection system comprises a power supply device 1 for electrical connection with the transmitter, a pressure detection device 2 for providing pressure for the transmitter, and a connecting device 3 for quick connection of the detection end of the transmitter, and the connecting device 3 is connected with the pressure detection device 2; when pressure detection of the transmitter is needed, the detection end of the transmitter is first connected with the connecting device 3; so that the detection end of the transmitter can be indirectly connected with the pressure detection device 2.

[0054] Then the power supply device 1 is connected with the corresponding port of the transmitter, and then the pressure detection of the transmitter can be carried out by cooperation of the pressure detection device 2 and the power supply device 1; the connecting device 3 can quickly connect the transmitter ports of different diameters, and after the pressure detection of the transmitter is completed, the transmitter can also be quickly detached from the connecting device 3, which on the one hand improves the efficiency of the pressure detection of the transmitter, and on the other hand improves the applicability of the application.

[0055] Referring to Figures 4 to 8 As shown in the figure, the connecting device 3 in the application; specifically, the connecting device 3 comprises a mounting main plate 30, a plurality of support legs 31 in annular distribution are uniformly arranged at the lower end of the mounting main plate 30, the support legs 31 can support the mounting main plate 30, so that the lower end of the mounting main plate 30 has some space for mounting parts; a connecting through slot 301 is formed in the middle of the mounting main plate 30, a connecting sleeve 32 in cylindrical structure and of elastic material is arranged at the upper end of the connecting through slot 301, a test through slot 302 is formed in the middle of the connecting sleeve 32, a connecting pipe 33 passing through the connecting through slot 301 is arranged at the lower end of the test through slot 302, the connecting pipe 33 is connected with the pressure detection device 2, the fluid for detection in the pressure detection device 2 can enter into the detection end of the transmitter through the connecting pipe 33 and the connecting sleeve 32, so that the transmitter can be detected by the pressure detection device 2.

[0056] An inner clamping ring groove 303 is formed at the lower end of the connecting sleeve 32 outside the test through slot 302, an insertion ring groove 304 for insertion of the transmitter is formed at the upper end of the connecting sleeve 32, an outer clamping unit 35 for clamping from the outside of the connecting pipe 33 is arranged at the upper end of the mounting main plate 30, and a control unit 36 is arranged at the outside of the outer clamping unit 35; after the detection end of the transmitter is inserted into the insertion ring groove 304, the outer clamping unit 35 can be driven by the control unit 36 to clamp the outside of the connecting sleeve 32, so that the connecting sleeve 32 can seal the outside of the detection end of the transmitter, and the transmitter can be indirectly connected with the pressure detection device 2.

[0057] Referring to Figure 9As shown, the outer clamping unit 35 for clamping and sealing the outer side of the connecting sleeve 32 in the application; specifically, the outer clamping unit 35 includes a limiting guide frame 350, a mounting block 351, a reset tension spring rod one 352, a clamping outer rod 353, and a driven push rod 354. The limiting guide frame 350 corresponding to the supporting leg 31 is annularly arranged on the upper end of the mounting main plate 30 and located outside the connecting slot 301. The opposite sides of the upper end of the mounting main plate 30 located away from the limiting guide frame 350 are each provided with a mounting block 351. The side of the mounting block 351 close to the limiting guide frame 350 is provided with a reset tension spring rod one 352. The opposite side of the reset tension spring rod one 352 is provided with a clamping outer rod 353 which passes through the corresponding limiting guide frame 350 and is provided with a driven push rod 354 driven by the control unit 36.

[0058] The reset tension spring rod one 352 can always provide the clamping outer rod 353 and the driven push rod 354 with a force away from the connecting sleeve 32. When the driven push rod 354 is driven by the control unit 36 to move towards the side close to the connecting sleeve 32, the clamping outer rod 353 can clamp the outer side of the connecting sleeve 32 under the action of the driven push rod 354, so that the connecting sleeve 32 can fix the detection end of the transmitter. When the driven push rod 354 is not pressed by the control unit 36, the reset tension spring rod one 352 will drive the clamping outer rod 353 and the driven push rod 354 to move away from the connecting sleeve 32. Then the transmitter can be taken out upwards, and the limiting guide frame 350 can limit and guide the movement track of the clamping outer rod 353.

[0059] Embodiment Two:

[0060] Continuing to refer to Figure 9 As shown, on the basis of embodiment one, it can be seen from the above disclosed technical solution that only the clamping outer rod 353 can clamp the connecting sleeve 32, and the area contacted by the clamping outer rod 353 and the connecting sleeve 32 is small, so the clamping effect is poor. Therefore, in order to improve the clamping effect of the clamping outer rod 353, an extension clamping unit 37 is arranged on the outer side of the clamping outer rod 353. Specifically, the extension clamping unit 37 includes an arc-shaped extension plate 370, an arc-shaped groove 371, a reset compression spring 372, and an extension abutting plate 373.

[0061] The arc-shaped extension plate 370 made of metal material and having elastic properties is sleeved on the outer side of the clamping outer rod 353. When the clamping outer rod 353 clamps the connecting sleeve 32, the arc-shaped extension plate 370 can increase the contact area with the connecting sleeve 32, thereby improving the clamping effect of the clamping outer rod 353 on the connecting sleeve 32. The elastic properties of the arc-shaped extension plate 370 make it applicable to transmitters with different diameters of detection ends.

[0062] Two sides of the arc-shaped extension plate 370 are symmetrically provided with arc-shaped grooves 371, and a return compression spring 372 is arranged in the arc-shaped groove 371 close to the clamping outer rod 353. An extension resisting plate 373 is arranged at the end of the return compression spring 372 away from the clamping outer rod 353 and is in sliding connection with the arc-shaped groove 371. The return compression spring 372 can always provide the extension resisting plate 373 with a force to move away from the arc-shaped groove 371. When the arc-shaped extension plate 370 clamps the connecting sleeve 32, the extension resisting plate 373 can extend outwardly from the arc-shaped groove 371 under the elastic action of the return compression spring 372. When two adjacent extension resisting plates 373 abut against each other, the arc-shaped extension plate 370 can more stably clamp the connecting sleeve 32, thereby improving the clamping effect of the arc-shaped extension plate 370.

[0063] Referring to Figure 10 and Figure 11 As shown in the figures, in order to further improve the clamping effect of the extension clamping unit 37 and to clamp the transmitter with a larger diameter detection end, a controlled auxiliary clamping unit 38 is arranged to clamp the two ends of the arc-shaped extension plate 370. Specifically, the auxiliary clamping unit 38 includes a limiting strip frame 380, a return tension spring rod two 381, an auxiliary clamping rod 382, an auxiliary clamping arc plate 383, a clamping rod 384 and a driven push block 385.

[0064] A plurality of limiting strip frames 380 staggered with the limiting guide frame 350 are arranged on the upper end of the mounting main plate 30, and the opposite side of the limiting strip frame 380 is located on the upper side of the connecting through groove 301. The opposite side of the limiting strip frame 380 on the mounting main plate 30 is also provided with a mounting block 351. The mounting block 351 is provided with a return tension spring rod two 381 close to the limiting strip frame 380. The opposite end of the return tension spring rod two 381 passes through the limiting strip frame 380 and is provided with an auxiliary clamping rod 382. The return tension spring rod two 381 can always provide the auxiliary clamping rod 382 with a force to move away from the connecting sleeve 32. When the auxiliary clamping rod 382 moves to the side close to the connecting sleeve 32 under the extrusion of the control unit 36, it can also clamp the outer side of the connecting sleeve 32. The limiting guide frame 350 can limit and guide the movement track of the auxiliary clamping rod 382.

[0065] The upper end of the auxiliary clamping rod 382 is sleeved with an auxiliary clamping arc plate 383 with elastic properties, which improves the clamping effect of the auxiliary clamping rod 382; the two sides of the auxiliary clamping arc plate 383 are symmetrically provided with clamping rod grooves, and clamping rods 384 are penetratingly arranged in the clamping rod grooves; the upper ends of the two clamping rods 384 located on the same auxiliary clamping arc plate 383 are jointly provided with a T-shaped structure driven push block 385 driven by the control unit 36; when the driven push block 385 is driven by the control unit 36 to move towards the side close to the connecting sleeve 32, it can drive the two ends of the auxiliary clamping arc plate 383 to clamp towards the side close to the connecting sleeve 32 through the clamping rods 384, and the force received by the clamping rods 384 further improves the clamping effect of the auxiliary clamping arc plate 383; the elastic properties of the auxiliary clamping arc plate 383 also make it applicable to upper transmitters with different diameters.

[0066] The upper end of the auxiliary clamping rod 382 is sleeved with an auxiliary clamping arc plate 383 with elastic properties, which improves the clamping effect of the auxiliary clamping rod 382; the two sides of the auxiliary clamping arc plate 383 are symmetrically provided with clamping rod grooves, and clamping rods 384 are penetratingly arranged in the clamping rod grooves; the upper ends of the two clamping rods 384 located on the same auxiliary clamping arc plate 383 are jointly provided with a T-shaped structure driven push block 385 driven by the control unit 36; when the driven push block 385 is driven by the control unit 36 to move towards the side close to the connecting sleeve 32, it can drive the two ends of the auxiliary clamping arc plate 383 to clamp towards the side close to the connecting sleeve 32 through the clamping rods 384, and the force received by the clamping rods 384 further improves the clamping effect of the auxiliary clamping arc plate 383; the elastic properties of the auxiliary clamping arc plate 383 also make it applicable to upper transmitters with different diameters.

[0067] Referring to Figure 12 and Figure 13 , that is, the control unit 36 in the present application for extruding the driven push block 385 and the driven push rod 354 from the outside to the inside; specifically, the control unit 36 comprises a lifting groove 360, a lifting rod 361, a sawtooth groove 362, a fixing assembly 39, a control sleeve ring 363 and an extension ring 364, the lifting groove 360 is provided on the supporting leg 31, the lifting rod 361 is penetratingly arranged in the lifting groove 360 through upward and downward sliding fit, the opposite sides of the lifting rod 361 are provided with sawtooth grooves 362, the supporting leg 31 is provided with a fixing assembly 39 for fixing the lifting rod 361 through the sawtooth grooves 362, the upper end of the lifting rod 361 penetrates through the installation main plate 30 and is in sliding fit with it, the control sleeve ring 363 is provided between the upper ends of the lifting rod 361, and the vertical section of the control sleeve ring 363 is similar to an "eight" shaped structure.

[0068] The upper end of the control sleeve ring 363 is provided with an extension ring 364 which is integrally formed with the control sleeve ring 363 and extends inwardly; when the control sleeve ring 363 and the lifting rod 361 are driven to move downward, the inner wall of the control sleeve ring 363 can extrude the driven push block 385 and the driven push rod 354, so as to move the side close to the connecting sleeve 32 and clamp it; the extension ring 364 can always be located above the driven push block 385 and the driven push rod 354, so as to avoid that when the control sleeve ring 363 is pressed downward, the driven push block 385 and the driven push rod 354 are separated from the inner wall of the control sleeve ring 363 and located on the upper side of the control sleeve ring 363; after the lifting adjustment of the control sleeve ring 363 is completed, the height of the control sleeve ring 363 can be quickly locked through the fixing assembly 39.

[0069] With reference to the accompanying drawings Figure 12 and Figure 13 As shown in FIG. 3, FIG. 4 and FIG. 5, i.e. the fixing assembly 39 for fixing the height of the control collar 363; the fixing assembly 39 comprises pressing rods 390, pressing links 391, driven links 392, sawtooth blocks 393, locking tooth grooves 394, support blocks 395, upward pulling spring rods 396, gear rods 397 and limit gear 398, the L-shaped pressing rods 390 slide through the installation main plate 30 and are located on both sides of the support leg 31, the pressing links 391 are arranged between the upper ends of the pressing rods 390, when the pressing links 391 are pressed downward or pulled upward, all the pressing rods 390 can be moved downward or upward.

[0070] The driven links 392 are arranged between the lower ends of the adjacent two pressing rods 390 and are located inside the sawtooth groove 362, the sawtooth blocks 393 are also slidably arranged at the upper ends of the driven links 392, the locking tooth grooves 394 are arranged at the upper ends of the sawtooth blocks 393 and correspond to the sawtooth groove 362, when the pressing rods 390 move up and down, the driven links 392 and the sawtooth blocks 393 can be moved together; the support blocks 395 are symmetrically arranged on one side of the support leg 31 close to the sawtooth groove 362 and are located at the upper ends of the sawtooth blocks 393, and the support blocks 395 are located below the installation main plate 30, the upward pulling spring rods 396 are arranged at the lower ends of the support blocks 395 and are connected with the driven links 392, the upward pulling spring rods 396 can always provide upward force for the driven links 392, the sawtooth blocks 393, the pressing rods 390 and the pressing links 391.

[0071] The gear rods 397 are rotatably arranged between the support blocks 395 on the same support leg 31, and the limit gears 398 are arranged on the outer sides of the gear rods 397 and mesh with the corresponding sawtooth grooves 362; when the sawtooth blocks 393 are upwardly clamped with the limit gears 398 under the action of the upward pulling spring rods 396, the lifting rods 361 meshed with the limit gears 398 cannot move up and down, thereby fixing the lifting rods 361 and the control collar 363.

[0072] If the height of the control collar 363 needs to be adjusted, the pressing links 391 need to be pressed downward first, so that the pressing links 391 can drive the pressing rods 390, the driven links 392 and the sawtooth blocks 393 to move downward, so that the sawtooth blocks 393 no longer clamp the limit gears 398, and then the height of the control collar 363 can be adjusted, when the adjustment of the control collar 363 is completed, the pressing links 391 are no longer pressed downward, so that the driven links 392, the sawtooth blocks 393, the pressing rods 390 and the pressing links 391 can all move upward and reset, and the sawtooth blocks 393 which can slide automatically can better clamp the limit gears 398.

[0073] Example Three:

[0074] Referring to Figure 14 As shown in the embodiment two, on the basis of the above disclosed technical solutions, the outer clamping unit 35, the extension clamping unit 37 and the auxiliary clamping unit 38 can only clamp the detection end of the transmitter from the outside to the inside, but cannot clamp the detection end of the transmitter from the inside to the outside. Therefore, in order to further improve the clamping effect on the detection end of the transmitter, the inner clamping unit 34 is arranged through the connecting channel 301 at the lower end of the inner clamping ring groove 303. Specifically, the inner clamping unit 34 comprises a mounting middle block 340, a pressing spring rod 341, an inner clamping rod 342, a limiting rod 343, an anti-dropping plate 344, a ring-shaped frame 345, an adjusting assembly 310, a connecting inner plate 346 and a control inner ring 347.

[0075] The mounting middle block 340 is arranged in the limiting strip frame 380. The mounting middle block 340 is provided with the pressing spring rod 341 on the side close to the connecting pipe 33. The opposite end of the pressing spring rod 341 is provided with the inner clamping rod 342 located in the inner clamping ring groove 303. The pressing spring rod 341 can always provide the inner clamping rod 342 with a force for moving inward. The limiting strip frame 380 can limit and guide the movement track of the inner clamping rod 342. When the inner clamping rod 342 moves outward, the detection end of the transmitter can be clamped from the inside to the outside.

[0076] The lower end of the mounting main plate 30 is provided with the limiting rod 343 corresponding to the limiting strip frame 380. The lower end of the limiting rod 343 is provided with the anti-dropping plate 344. The ring-shaped frame 345 is slidably arranged between the limiting rods 343. The outer side of the ring-shaped frame 345 is provided with the adjusting assembly 310. The adjusting assembly 310 can drive the ring-shaped frame 345 to move up and down and can fix the position after moving. The inner side of the ring-shaped frame 345 is uniformly provided with the connecting inner plate 346 corresponding to the supporting leg 31. The connecting inner plates 346 are staggered with the inner clamping rods 342. The opposite sides of the connecting inner plates 346 are provided with the control inner ring 347.

[0077] The vertical section of the control inner ring 347 is also similar to the "eight" character-shaped structure. The upper end of the control inner ring 347 is located between the inner clamping rods 342. When the control inner ring 347 moves upward, it can drive all the inner clamping rods 342 to move outward together, so that the inner clamping rods 342 can clamp the detection end of the transmitter from the inside to the outside. When the control inner ring 347 moves upward, the inner clamping rods 342 will not abut against the connecting inner plates 346, so as not to interfere with the movement track of the control inner ring 347. When the control inner ring 347 is driven downward by the adjusting assembly 310, the inner clamping rods 342 will not clamp the detection end of the transmitter.

[0078] Referring to Figure 14 andFigure 15 The adjusting assembly 310 in the application is shown, and specifically, the adjusting assembly 310 comprises a connecting outer plate 311, a connecting ring 312, a T-shaped adjusting plate 313, a containing groove 314, a rotating ring plate 315, a limiting arc block 316 and a limiting tooth groove 317. The connecting outer plate 311 corresponding to the limiting rod 343 is arranged on the outer side of the annular frame 345, the connecting ring 312 is arranged between the opposite sides of the connecting outer plate 311, and the T-shaped adjusting plate 313 is uniformly arranged on the upper end of the connecting ring 312 and penetrates through the mounting main plate 30 and is in sliding fit with the mounting main plate 30. The connecting ring 312 can drive the connecting outer plate 311 and the T-shaped adjusting plate 313 to move up and down together for adjustment, and the T-shaped adjusting plate 313 can limit and guide the movement track of the connecting ring 312. When the connecting ring 312 moves up and down, the control inner ring 347 can also be indirectly driven to move.

[0079] The mounting main plate 30 is provided with the containing groove 314 on one side of the T-shaped adjusting plate 313, the mounting main plate 30 is in a circular structure, the rotating ring plate 315 is rotatably arranged on the outer side of the mounting main plate 30, the limiting arc block 316 is arranged in the containing groove 314 on the inner side of the rotating ring plate 315, and the limiting tooth groove 317 is arranged on the inner side of the limiting arc block 316 and the opposite side of the T-shaped adjusting plate 313. When the height adjustment of the control inner ring 347 is completed, rotating the rotating ring plate 315 can drive the limiting arc block 316 to move, and the limiting arc block 316 can make the limiting tooth groove 317 on the rotating process be engaged with the limiting tooth groove 317 on the T-shaped adjusting plate 313, so as to fix the position of the T-shaped adjusting plate 313 and indirectly fix the height of the control inner ring 347.

[0080] In addition, the application also provides a preparation detection method of the transmitter, which comprises the following steps: S1, inserting the detection end on the transmitter into the plug-in ring groove 304, then driving the outer clamping unit 35, the extending clamping unit 37 and the auxiliary clamping unit 38 to clamp the outer side of the connecting pipe 33 through the control unit 36, and clamping the inner wall of the detection end of the transmitter from inside to outside through the inner clamping unit 34, so that the transmitter can be indirectly connected with the pressure detection device 2.

[0081] S2, connecting the power supply device 1 with the corresponding port on the transmitter, and then detecting the pressure of the transmitter through the cooperation of the pressure detection device 2 and the power supply device 1.

[0082] S3, after the detection of the transmitter is completed, the outer clamping unit 35, the extending clamping unit 37 and the auxiliary clamping unit 38 are no longer clamped to the outer side of the detection end of the transmitter through the control unit 36, the inner clamping unit 34 is no longer clamped to the inner wall of the detection end of the transmitter, then the power supply device 1 is operated to be no longer electrically connected with the transmitter, and finally the transmitter is taken out.
