Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flowmeter calibration, in particular to a calibration structure for an electromagnetic flowmeter. Background Art
[0002] Electromagnetic flowmeter is an instrument for measuring the flow of conductive fluids made using Faraday's law of electromagnetic induction. It can linearly transform the flow signal into the corresponding induced electromotive force. The flow of the conductive fluid can be determined by measuring the induced electromotive force. The electromagnetic flowmeter includes a sensor and a transmitter connected to the sensor. The sensor is used to measure the electromotive force induced by the conductive fluid when it passes through an external magnetic field due to cutting the magnetic lines of force, and the electromotive force signal is extracted and transmitted to the transmitter. The transmitter amplifies the tiny electromotive force signal measured and output by the sensor, and converts it into a standard voltage or current signal proportional to the flow of the measured fluid, and then outputs the processed signal to the display and / or remote client to display the measured fluid flow.
[0003] When the existing electromagnetic flowmeter calibration structure is used, the electromagnetic flowmeter is usually placed directly on the workbench for calibration. However, when the electromagnetic flowmeter is calibrated, the electromagnetic flowmeter is prone to shaking, which leads to reduced accuracy of the calibration result.

When a calibration device is needed to calibrate flowmeters of multiple different specifications, calibration equipment of different specifications needs to be prepared in advance, which reduces the scope of use of the equipment.

[0033] The implementation principle of this embodiment is:
[0034] The calibration structure of the electromagnetic flowmeter is provided with a support block 11. When using the device, the staff puts the flowmeter on the top of the support block 11, and then the staff starts the cylinder 3. The cylinder 3 can push the first telescopic rod 4 to extend and retract. The extension and retraction of the first telescopic rod 4 can drive the fixed frame 12 to move. Since a slider 29 is provided at the bottom of the fixed frame 12, the slider 29 can move inside the slide groove 2, so that the fixed frame 12 can move. The movement of the fixed frame 12 can drive the lifting plate 9 to move, and then drive the clamping mechanism 10 to move. When the clamping mechanism 10 enters the interior of the flowmeter, the staff starts the first motor 13. The first motor 13 starts to work and can drive the first threaded rod 14 to rotate. The first threaded rod 14 is rotated. The rotation of the threaded rod 14 can make the threaded sleeve 15 move up and down, and the up and down movement of the threaded sleeve 15 can drive the lifting plate 9 to move up and down. Since the lifting block 17 can slide on the outer surface of the auxiliary rod 16, the lifting plate 9 can be moved, and the movement of the lifting plate 9 can drive the clamping mechanism 10 to move. Since the sliding block 28 can move inside the sliding groove 8, the connecting block 21 can be moved up and down, and the clamping mechanism 10 can be moved, which can drive the flow meter to move. When it moves to the appropriate position, the staff turns off the first motor 13. At this time, the support block 11 can support the flow meter, so that the equipment can be suitable for flow meters of different specifications, thereby expanding the scope of use of the equipment.
[0035] Afterwards, the staff starts the second motor 19, and the second motor 19 starts working, which can drive the second threaded rod 20 to rotate. Due to the limiting effect of the sliding block 28 on the connecting block 21, the connecting block 21 can be prevented from rotating. Since a second telescopic rod 27 is provided on one side of the connecting block 21, the movable block 25 can be prevented from rotating, and the movable block 25 can be moved. The movement of the movable block 25 can drive one end of the second connecting rod 24 to move. Since the first connecting rod 22 is rotatably connected with the second connecting rod 24, the second connecting rod 24 can be rotated, and the clamping block 23 can be moved, and the clamping block 23 can be contacted with the inner wall of the flow meter, so that the flow meter can be fixed, thereby preventing the flow meter from moving during the calibration process, thereby improving the accuracy of the calibration result. Afterwards, the staff can calibrate the flow meter.
[0036] Compared with the prior art, the present invention has the following beneficial effects:
[0037] 1. The electromagnetic flowmeter calibration structure is provided with a clamping mechanism 10, and the second threaded rod 20 can be driven to rotate by the rotation of the second motor 19, so that the clamping block 23 can be moved, so that the clamping block 23 can contact the inner wall of the flowmeter, so that the calorimeter can be fixed, so as to improve the accuracy of the calibration result;
[0038] 2. The calibration structure for the electromagnetic flowmeter is provided with a lifting mechanism 5, which can drive the first threaded rod 14 to rotate through the first motor 13, so that the lifting plate 9 can move up and down, and the fixed frame 12 can be moved through the cylinder 3, so that the equipment can calibrate flow meters of different specifications, thereby expanding the scope of use of the equipment.
