Technical Field

[0001] This utility model relates to a tubular flow meter, and more particularly to a tubular flow meter calibration device. Background Technology

[0002] The primary function of a tubular flowmeter calibration device is to ensure the accuracy and reliability of the flowmeter's measurements. Over long-term use, the measurement accuracy of a tubular flowmeter may decrease due to wear, corrosion, scaling, and other factors. The calibration device calibrates the flowmeter by providing fluid with a known, accurate flow rate, correcting measurement errors and enabling it to accurately measure fluid flow under different operating conditions, thus providing accurate flow data for industrial production.

[0003] Existing tubular flow meter calibration devices require measuring the pipe diameter using a π ruler before use. This reading is prone to errors, and the measurement operation is relatively complex and time-consuming, resulting in low calibration efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a tubular flow meter calibration device that can automatically fix itself to the surface of the tubular flow meter and directly measure the diameter of the pipe, thereby improving calibration efficiency and making it convenient to carry and move.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A tubular flowmeter calibration device is provided, comprising a calibration device body, the calibration device body including a calibrator, the surface of the calibrator being provided with a display, a first groove being formed on the right side surface of the calibrator, a control component being provided inside the calibrator, a connecting mechanism being installed on the lower surface of the calibrator, the connecting mechanism including a connecting plate, the upper surface of the connecting plate being fixedly connected to the lower surface of the calibrator, a rotating mechanism being installed on the surface of the connecting plate, the rotating mechanism including a first rotating rod, the surface of the first rotating rod being movably connected to the surface of the first groove, a fixing mechanism and a data acquisition mechanism being installed on the surface of the first rotating rod, the fixing mechanism being located above the data acquisition mechanism, the data acquisition mechanism including a second electric telescopic rod, the main body end of the second electric telescopic rod being fixedly connected to the right side surface of the first rotating rod, and a pressure plate being fixedly connected to the telescopic end of the second electric telescopic rod.

[0006] Optionally, the fixing mechanism includes a first electric telescopic rod, the main body end of which is fixedly connected to the right side surface of the first rotating rod, and the first electric telescopic rod is located above the second electric telescopic rod.

[0007] Optionally, a connecting block is fixedly connected to the telescopic end of the first electric telescopic rod, a second rotating shaft is fixedly connected to the surface of the connecting block, a second rotating rod is movably connected to the surface of the second rotating shaft, and an elastic membrane is fixedly connected to the surface of the second rotating rod.

[0008] Optionally, a first rotating shaft is fixedly connected to the surface of the connecting plate, the surface of the first rotating shaft is movably connected to the inner wall of the first rotating rod, and a protrusion is fixedly connected to the surface of the first rotating rod.

[0009] Optionally, the inner wall of the connecting plate is provided with a third groove and a fourth groove, the third groove being located above the fourth groove and the protrusion being located inside the fourth groove.

[0010] Optionally, the calibrator has a second groove on its surface, and the inner wall of the second groove is fixedly connected to the surface of the display.

[0011] Optionally, the lower surface of the calibrator is provided with a connecting groove, the inside of the connecting groove is provided with a sliding groove, and a limiting mechanism is installed inside the sliding groove. The limiting mechanism includes a slider, the surface of the slider is movably connected to the inner wall of the sliding groove, an elastic plate is fixedly connected to the surface of the slider, and a push block is fixedly connected to the lower surface of the elastic plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention comprises a second electric telescopic rod, a pressure plate, and a first rotating rod. In use, the tubular flowmeter to be tested is placed between the two first rotating rods, ensuring the upper surface of the pipe within the flowmeter is in contact with the lower surface of the calibration device body. The first electric telescopic rod is then activated, causing the elastic membrane on the connecting block fixed to its telescopic end to contact the pipe surface. Four fixing mechanisms are used to secure the calibration device body to the surface of the tubular flowmeter. The second electric telescopic rod is then activated, causing the pressure plate fixed to its telescopic end to contact the tubular flowmeter surface. The control components inside the calibration device body collect data and calculate the diameter of the tubular flowmeter. This data is then transmitted to a display for calibration. This invention automatically fixes itself to the surface of the tubular flowmeter and directly measures the pipe diameter, improving calibration efficiency.

[0014] This utility model is equipped with a first electric telescopic rod, a protrusion, and an elastic plate. In use, when it is necessary to move this utility model, simply activate the first electric telescopic rod to retract it, and then turn the first rotating rod that is movably connected to the connecting plate. This causes the protrusion fixed on the surface of the first rotating rod to disengage from the fourth groove, allowing the rotating mechanism to be retracted into the connecting groove on the main body of the calibration device. When not under force, the elastic plate is in an unfolded state, with its upper surface fitting against the lower surface of the first rotating rod, preventing the first rotating rod from falling out of the connecting groove due to shaking. This facilitates the storage of the rotating mechanism and makes it easy to carry and move. Attached Figure Description

[0028] Reference Figure 1-7The following describes the tubular flowmeter calibration device provided in this embodiment of the present invention. The tubular flowmeter calibration device includes a calibration device body 1, which includes a calibrator 101. A display 104 is provided on the surface of the calibrator 101. A second groove 103 is formed on the surface of the calibrator 101. A control component 107 is provided inside the calibrator 101. A connecting mechanism 2 is mounted on the lower surface of the calibrator 101. The connecting mechanism 2 includes a connecting plate 201, the upper surface of which is fixedly connected to the lower surface of the calibrator 101. A rotating mechanism 3 is mounted on the surface of the connecting plate 201, including a first rotating rod 301. The surface of the first rotating rod 301 is movably connected to the surface of the first groove 102. A fixing mechanism 4 and a data acquisition mechanism 5 are mounted on the surface of the first rotating rod 301. The fixing mechanism 4 is located above the data acquisition mechanism 5. The data acquisition mechanism 5 includes a second electric telescopic rod 501, the main body end of which is fixedly connected to the right side surface of the first rotating rod 301. The telescopic end of the telescopic rod 501 is fixedly connected to a pressure plate 502. The tubular flow meter to be tested is placed between the two first rotating rods 301, so that the upper surface of the pipe in the tubular flow meter is in contact with the lower surface of the calibration device body 101. The first electric telescopic rod 401 is activated, so that the elastic membrane 405 on the connecting block 402 fixed at the telescopic end of the first electric telescopic rod 401 contacts the surface of the pipe. There are four fixing mechanisms 4, which fix the calibration device body 101 on the surface of the tubular flow meter. At this time, the second electric telescopic rod 501 is activated, and the pressure plate 502 fixed at the telescopic end of the second electric telescopic rod 501 contacts the surface of the tubular flow meter. After the control component 107 inside the calibration device body 101 collects data, the diameter of the tubular flow meter can be obtained by calculating the distance between the two first rotating rods 301 minus the extension distance of the second electric telescopic rod 501 and the thickness of the pressure plate 502. The data is transmitted to the display 104 for calibration.

[0029] The fixing mechanism 4 includes a first electric telescopic rod 401, the main body end of which is fixedly connected to the right side surface of the first rotating rod 301. The first electric telescopic rod 401 is located above the second electric telescopic rod 501. A connecting block 402 is fixedly connected to the telescopic end of the first electric telescopic rod 401. A second rotating shaft 404 is fixedly connected to the surface of the connecting block 402. A second rotating rod 403 is movably connected to the surface of the second rotating shaft 404. An elastic membrane 405 is fixedly connected to the surface of the second rotating rod 403. A connecting plate 201 is also included. A first rotating shaft 302 is fixedly connected to the surface of the calibrator 101. The surface of the first rotating shaft 302 is movably connected to the inner wall of the first rotating rod 301. A protrusion 303 is fixedly connected to the surface of the first rotating rod 301. A third groove 202 and a fourth groove 203 are formed on the inner wall of the connecting plate 201. The third groove 202 is located above the fourth groove 203. The protrusion 303 is located inside the fourth groove 203. The inner wall of the second groove 103 is fixedly connected to the surface of the display 104. The right side of the calibrator 101 is... The calibrator 101 has a first groove 102 on its surface and a connecting groove 105 on its lower surface. A sliding groove 106 is formed inside the connecting groove 105, and a limiting mechanism 6 is installed inside the sliding groove 106. The limiting mechanism 6 includes a slider 602, the surface of which is movably connected to the inner wall of the sliding groove 106. An elastic plate 601 is fixedly connected to the surface of the slider 602, and a push block 603 is fixedly connected to the lower surface of the elastic plate 601. When it is necessary to move this utility model, simply activate the first electric telescopic rod 401 to retract it, and then pull the lever. The first rotating rod 301, which is movably connected to the connecting plate 201, allows the protrusion 303 fixed on the surface of the first rotating rod 301 to disengage from the fourth groove 203, so that the rotating mechanism 3 can be stored in the connecting groove 105 opened on the main body 101 of the calibration device. When the elastic plate 601 is not under force, it is in an unfolded state. The upper surface of the elastic plate 601 is in contact with the lower surface of the first rotating rod 301, preventing the first rotating rod 301 from falling out of the connecting groove 105 due to shaking. This makes it convenient to store the rotating mechanism 3 and to carry and move it.

[0030] Working principle: The tubular flow meter to be tested is placed between the two first rotating rods 301, so that the upper surface of the pipe in the tubular flow meter is in contact with the lower surface of the calibration device body 101. The first electric telescopic rod 401 is activated, so that the elastic membrane 405 on the connecting block 402 fixed at the telescopic end of the first electric telescopic rod 401 contacts the surface of the pipe. There are four fixing mechanisms 4, which fix the calibration device body 101 to the surface of the tubular flow meter. At this time, the second electric telescopic rod 501 is activated, and the pressure plate 502 fixed at the telescopic end of the second electric telescopic rod 501 contacts the surface of the tubular flow meter. After the control component 107 inside the calibration device body 101 collects data, it calculates the distance between the two first rotating rods 301 minus the distance between the two electric telescopic rods 501. The diameter of the tubular flow meter can be determined by the extension distance and the thickness of the pressure plate 502. The data is input to the display 104 for calibration. When the present invention needs to be moved, simply activate the first electric telescopic rod 401 to retract it, and then turn the first rotating rod 301, which is movably connected to the connecting plate 201, so that the protrusion 303 fixed on the surface of the first rotating rod 301 disengages from the fourth groove 203. The rotating mechanism 3 can then be stored in the connecting groove 105 opened on the main body 101 of the calibration device. The elastic plate 601 is in an unfolded state when not under force. The upper surface of the elastic plate 601 is in contact with the lower surface of the first rotating rod 301 to prevent the first rotating rod 301 from falling out of the connecting groove 105 due to shaking. This makes it convenient to store the rotating mechanism 3 and to carry and move it.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
