It integrates main control, track, reflective target, electrical acquisition and software. The control system precisely controls the liquid level, and the measurement system precisely measures the liquid level. Combined with the software, it can achieve fully automatic detection until the generation of printed certificates.

[0003] In oil and gas processing and gathering and transportation systems, as the equipment runs for a long time, some liquid level regulators and ultrasonic level gauges may fail, such as failure to automatically adjust or large fluctuations in values, which may even cause tank danger.

[0028] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] When the liquid level meter needs to be inspected, the calibration mobile trolley 8 carrying the liquid level meter is placed on the guide rail assembly 3, and the driving device 4 is started to make it move in a circle and drive the pushing assembly 5 to move at the same time, so that when the pushing assembly 5 moves in the opposite direction of the reflective target 2, it pushes the front push rod 6 to move to push the telescopic pushing mechanism 7 to extend and retract in the same direction and then push the connecting member 9 to move. When the connecting member 9 is pushed and displaced, a thrust is generated on the mobile trolley 8 to move the mobile trolley 8 on the guide rail assembly 3. When the driving device 4 continues to operate after running for one circle, it drives the pushing assembly 5 to move in the opposite direction, so that the telescopic pushing assembly 5 contracts in the opposite direction, that is, drives the connecting member 9 to move in the opposite direction and then drives the mobile trolley 8 to move in the opposite direction again, so that the mobile trolley 8 can automatically perform continuous reciprocating motion on the guide rail assembly 3.

[0032] The utility model connects the driving device 4 with the pushing component 5, and through the cooperation of the pushing component 5 and the telescopic pushing mechanism 7, the driving device 4 can drive the pushing component 5 to perform reciprocating translational motion during operation, thereby pushing or pulling the telescopic pushing mechanism 7 to perform telescopic expansion and contraction, and then cooperates with the connecting piece 9 to drive the moving trolley 8 to perform linear motion together, so that it can continuously perform reciprocating motion in the horizontal direction, and then the moving trolley 8 for level meter detection can continuously reciprocate on the guide rail component 3 by itself, thereby improving its detection efficiency and making it have a continuous detection effect.

[0033] In one embodiment, for the above-mentioned guide rail assembly 3, the guide rail assembly 3 includes a guide rail body 301, and the top of the guide rail body 301 is respectively provided with a central slide groove 302 and a bidirectional slide groove 303, and the bidirectional slide groove 303 is symmetrically arranged on both sides of the central slide groove 302.

[0034] By respectively setting a central slide groove 302 and a bidirectional slide groove 303 on the inner side of the guide rail body 301, the movement trajectory of the pushing component 5 and the telescopic pushing mechanism 7 can be limited through the setting of the central slide groove 302, so that the telescopic pushing mechanism 7 can provide a linear motion limiting effect for the moving cart 8.

[0035] In one embodiment, for the above-mentioned driving device 4, the driving device 4 includes a driving motor 401, and a connecting plate 402 is fixedly installed on the output end of the driving motor 401. The top of the connecting plate 402 is fixedly connected with a guide column 403, and one end of the pushing component 5 is sleeved on the outside of the guide column 403.

[0036] When the driving motor 401 is started, it drives the connecting rotating plate 402 to rotate, and the guide column 403 at one end of the top thereof rotates along the inner wall of the pushing component 5, thereby driving the pushing component 5 to move horizontally, thereby providing displacement driving force for the pushing component 5.

[0037] In one embodiment, for the above-mentioned pushing component 5, the pushing component 5 includes an annular plate 501, the outer surface of the annular plate 501 is fixedly connected to a pushing plate 502, one end of the pushing plate 502 is fixedly connected to a second annular plate 503, the bottom of the pushing plate 502 is fixedly connected to a bottom slider 504, and the bottom slider 504 is slidably connected to the inside of the central slide groove 302.

[0038] The guide column 403 is located in the annular groove on the inner side of the annular plate 501. When the connecting plate 402 drives the guide column 403 to operate, the guide column 403 slides along the inner side of the annular plate 501 while operating, thereby limiting and driving the annular plate 501 to move. At the same time, the pushing plate 502 pushes the second annular plate 503 to move, thereby pushing the push rod 6 to move to push the telescopic pushing mechanism 7 to perform telescopic displacement. The guide column 403 rotates one circle and drives the annular plate 501 to move back and forth once. At the same time, the bottom slider 504 at the bottom of the annular plate 501 slides inside the central slide groove 302 to limit the displacement path of the annular plate 501.

[0039] By restricting the guide column 403 in the annular groove of the annular plate 501, the guide column 403 always moves along the inner side of the annular plate 501 during continuous operation, thereby being able to provide continuous displacement driving force for the annular plate 501, thereby indirectly providing continuous displacement driving force for the telescopic pushing mechanism 7 and the moving trolley 8, so that the moving trolley 8 can perform reciprocating motion to perform detection operations.

[0040] In one embodiment, for the above-mentioned telescopic pushing mechanism 7, the telescopic pushing mechanism 7 includes a connecting frame 701, the bottom of the connecting frame 701 is fixedly connected to a column 702, the column 702 is fixedly connected to the inside of the central slide groove 302, one end of the connecting frame 701 is rotatably installed with a telescopic frame 703, the telescopic frame 703, one end of the connecting member 9 is rotatably connected to the bottom end of the telescopic frame 703.

[0041] The top rod 6 is located at the top of the connecting frame 701. When the second annular plate 503 pushes the top rod 6 to move, the top rod 6 drives the connecting frame 701 to extend and retract. At the same time, the column 702 at the bottom limits the initial end of the connecting frame 701, so that the other end of the connecting frame 701 pushes the telescopic frame 703 to extend and retract. At the same time, the telescopic frame 703 pushes the connecting piece 9 and the moving trolley 8 to move on the guide rail body 301.

[0042] By connecting the connecting piece 9 to the end of the telescopic frame 703, when the connecting frame 701 and the matching push rod 6 are telescoped and expanded, the telescopic frame 703 is driven to expand to push the moving trolley 8 to move in the far direction. When the annular plate 501 is driven to move toward the direction of the reflective target 2, the telescopic frame 703 is simultaneously driven to contract in the opposite direction to drive the connecting piece 9 and the moving trolley 8 to move in the opposite direction. In this way, the moving trolley 8 can be provided with a displacement driving force while limiting its displacement path on the guide rail body 301, so that it always moves in a straight line along the original path, so as to limit its displacement path and distance during detection, thereby improving the operating efficiency and continuity of the detection operation during the level meter detection process.

[0043] In one embodiment, for the above-mentioned connecting member 9, the connecting member 9 includes a connecting plate 901, one end of the connecting plate 901 is fixedly connected to a circular plate 902, the bottom of the circular plate 902 is fixedly connected to a guide sliding block 903, and the guide sliding block 903 is slidably connected to the inside of the central sliding groove 302.

[0044] By connecting the connecting plate 901 with the bottom of the moving trolley 8, when the telescopic frame 703 is expanded and retracted, the circular plate 902 is driven to move, and the connecting plate 901 drives the moving trolley 8 to move together. At the same time, the guide slider 903 at the bottom is driven to slide along the inside of the central slide groove 302, so as to limit the displacement path of the connecting plate 901 so that it and the telescopic frame 703 restrict each other and always move along the same horizontal line.

[0045] In one embodiment, for the above-mentioned moving cart 8 , guide wheels 11 are provided at the bottom of the moving cart 8 . There are several groups of guide wheels 11 , and the several groups of guide wheels 11 are all located inside the bidirectional slide groove 303 .

[0046] By setting multiple sets of guide wheels 11 at the bottom of the moving trolley 8, the guide wheels 11 can drive the moving trolley 8 to move along the direction of the two-way slide groove 303, so that the moving trolley 8 can always move along the center direction of the guide rail body 301 under various restrictions, so that it is more stable during displacement.

[0047] In one embodiment, for the above-mentioned buffer mechanism 10, the buffer mechanism 10 includes a fixed vertical rod 1011, the outer surface of the fixed vertical rod 1011 is fixedly connected to a spring column 1012, one end of the spring column 1012 is fixedly connected to a buffer seat 1013, the bottom of the buffer seat 1013 is fixedly connected to a bottom sliding column 1014, and the bottom sliding column 1014 is slidably connected to the inside of the central sliding groove 302.

[0048] By supporting the fixed vertical rod 1011 on the inner side of the central slide groove 302, when the moving cart 8 moves to a position close to the buffer seat 1013, its spring column 1012 is pushed back and drives the bottom slide column 1014 to slide inside the central slide groove 302. During the continuous compression of the spring column 1012, the moving cart 8 is gradually driven to move in the opposite direction to release the resistance to the buffer seat 1013, so that the spring column 1012 rebounds and resets. In this way, the moving cart 8 can have a buffering effect when it moves to the end, preventing it from shaking during the reciprocating motion and affecting the detection accuracy.

[0049] Through the above technical solution, 1. By connecting the driving device 4 with the pushing component 5, and through the cooperation of the pushing component 5 and the telescopic pushing mechanism 7, the driving device 4 can drive the pushing component 5 to perform a reciprocating translational motion during operation, thereby pushing or pulling the telescopic pushing mechanism 7 to perform a telescopic expansion and contraction action, and then cooperate with the connecting member 9 to drive the mobile trolley 8 to perform a linear motion together, so that it can continuously perform a horizontal reciprocating motion, and then the mobile trolley 8 for level meter detection can be automatically displaced back and forth on the guide rail component 3 continuously, thereby improving its detection efficiency and making it have a continuous detection effect; 2. By connecting the connecting member 9 with the telescopic pushing mechanism 7, the driving device 4 can drive the pushing component 5 to perform a reciprocating translational motion during operation, thereby pushing or pulling the telescopic pushing mechanism 7 to perform a telescopic expansion and contraction action, and then cooperate with the connecting member 9 to drive the mobile trolley 8 to perform a linear motion together, so that it can continuously perform a horizontal reciprocating motion, and then the mobile trolley 8 for level meter detection can be automatically displaced back and forth on the guide rail component 3 continuously, thereby improving its detection efficiency and making it have a continuous detection effect; The end of the retractable frame 703 is connected. When the connecting frame 701 and the matching push rod 6 are retracted and expanded, the retractable frame 703 is driven to expand to push the mobile cart 8 to move in the far direction. When the annular plate 501 is driven to move toward the direction of the reflective target 2, the retractable frame 703 is simultaneously driven to retract in the opposite direction to drive the connecting piece 9 and the mobile cart 8 to move in the opposite direction. In this way, the mobile cart 8 can be provided with a displacement driving force while limiting its displacement path on the guide rail body 301, so that it always moves in a straight line along the original path, so as to limit its displacement path and distance during detection, thereby improving the operating efficiency and continuity of the detection operation during the level meter detection process.
