Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of temperature measurement, in particular to an auxiliary calibration platform for a temperature transmitter. Background Art
[0002] Transformer temperature monitoring uses a thermal resistor temperature transmitter, which converts the temperature signal into a 4-20mA DC current, which is then sent to a secondary instrument or other data acquisition system for temperature display. The use of a temperature transmitter is crucial for monitoring transformer temperature, so before commissioning, it is important to ensure that the transmitter and display meet quality requirements. A calibration bench is often used to assist in the calibration process. By connecting the calibrated temperature transmitter to a standard temperature source and measurement system, and comparing the transmitter output with the standard value, the system can determine whether it is operating within the allowable error range.
[0003] Traditional temperature transmitter calibration benches can typically only operate on one temperature transmitter at a time. When a temperature transmitter is calibrated and the test target needs to be replaced, the system often requires a long downtime to remove and install the new temperature transmitter. This not only seriously affects the efficiency of the calibration work, but can also cause delays in the entire production or experimental process due to long downtime. In addition, the sockets of existing calibration benches often lack effective dust protection measures. Dust can easily enter the sockets, which can cause problems such as poor contact and unstable signal transmission, thereby affecting the accuracy of the calibration results. Long-term accumulation of dust can also damage the sockets and related electrical components, increasing the maintenance cost and difficulty of the equipment.
[0004] Therefore, it is necessary to provide a temperature transmitter auxiliary calibration platform to solve the above technical problems. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings and implementation examples.
[0021] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of a temperature transmitter auxiliary calibration platform provided by the present invention; Figure 2 for Figure 1 The schematic diagram of the top view of the temperature transmitter auxiliary calibration bench shown; Figure 3 for Figure 2 The internal structure diagram of the fixed card block shown; Figure 4 for Figure 1 Schematic diagram of the connection between the sliding connection block and the connection plate shown; Figure 5 for Figure 1 The schematic diagram of the structure of the dustproof frame shown. A temperature transmitter auxiliary calibration table includes: a calibration table 1, a sliding groove 2 is provided on the top of the calibration table 1, a sliding connection block 3 is slidably connected inside the sliding groove 2, a connecting plate 4 is fixedly connected to the top of the calibration table 1, a controller 5 is installed on the back of the connecting plate 4, a fixing frame 6 is fixedly connected to the top of the calibration table 1 on both sides of the sliding groove 2, a fixing card slot 7 is provided on the fixing frame 6, a fixing card hole 8 is provided inside the fixing card slot 7, a fixing card block 9 is fixedly connected to both sides of the sliding connection block 3, two synchronization plates 10 are slidably connected inside the fixed card block 9, a synchronization slide rail 11 is fixedly connected inside the fixed card block 9, and a pressing block is fixedly connected to the synchronization plate 10. 12. A fixed clamping rod 13 is fixedly connected to the synchronization plate 10, a synchronization spring 14 is fixedly connected between the two synchronization plates 10, a contact groove 15 is provided on the connection plate 4, a spring 17 is fixedly connected to the sliding connection block 3, a contact protrusion 16 is fixedly connected to the spring 17, and a plurality of plug holes 23 are provided on the sliding connection block 3. The traditional calibration table needs to be shut down for a long time when the detection target is replaced. While the present patent calibrates one temperature transmitter, it can clamp and prepare for electrical plugging of another temperature transmitter, which greatly reduces the idle time of the equipment and can complete more calibration work in the same time, thereby speeding up the production progress and improving the overall production efficiency.
[0022] A dustproof frame 18 is provided on the sliding connection block 3, and the dustproof frame 18 includes a dustproof frame 19. A dustproof plate 20 is slidably connected to the dustproof frame 19, and an inclined plate 21 is fixedly connected to the dustproof plate 20. A plug-in slot 22 is provided on the dustproof frame 19. When the connecting wire plug is plugged into the plug hole 23, the dustproof plate 20 blocks the plug hole 23 and pushes the plug forward. Due to the inclined plate 21, the dustproof plate 20 moves up to facilitate the plug to be inserted into the plug hole 23. When the verification is completed and the device is no longer used, the dustproof plate 20 will fall again due to gravity to ensure that dust does not enter the plug hole 23.
[0023] A clamping constant temperature bath 24 is provided on the top of the calibration table 1. A clamping baffle 25 is fixedly connected to the left side of the clamping constant temperature bath 24 on the top of the calibration table 1. The temperature transmitter is clamped in the clamping constant temperature bath 24. A heating wire is provided in the bath to provide a standard temperature source by changing the medium temperature. The clamping baffle 25 prevents the temperature transmitter from leaving the constant temperature clamping bath 24 due to excessive clamping.
[0024] Two clamping cylinders 26 are installed on the top of the calibration table 1. A telescopic rod 27 is slidably connected to the left side of the clamping cylinder 26. A fixed telescopic block 28 is fixedly connected to the telescopic rod 27. A movable telescopic block 29 is slidably connected inside the fixed telescopic block 28. A clamping plate 30 is fixedly connected to the movable telescopic block 29. A buffer pad 31 is provided on the clamping plate 30. When the clamping cylinder 26 is started, the telescopic rod 27 is extended. A spring buffer is provided between the fixed telescopic block 28 and the movable telescopic block 29 to avoid damage to the temperature transmitter due to excessive pressure.
[0025] Two control buttons 32 are provided on the top of the calibration table 1. A display screen 33 is installed on the calibration table 1. The controller 5 is electrically connected to the display screen 33 and the control button 32. Pressing the control button 32 can start the clamping cylinder 26 through the electrical connection. The controller 5 is also electrically connected to the measurement system. After the measurement system measures the data, the data will be transmitted to the display screen 33 through the controller 5, which is convenient for the calibration personnel to observe the test data and then calibrate the temperature transmitter.
[0026] The bottom of the calibration table 1 is fixedly connected to a lifting frame 34, on which a tool cabinet 35 is arranged. The bottom of the lifting frame 34 is fixedly connected to a base 36, and a tool cabinet 35 is arranged inside the lifting frame 34 for convenient storage of calibration tools and maintenance tools.
[0027] The working principle of the temperature transmitter auxiliary calibration station provided by this utility model is as follows:
[0028] When calibrating a temperature transmitter, a data line is required to connect the temperature transmitter to the measurement system. Since a traditional calibration device can usually only operate one temperature transmitter at a time, when the calibration of a temperature transmitter is completed and the detection target needs to be replaced, it is often necessary to stop the machine for a long time to disassemble and install a new temperature transmitter. The sliding connection block 3 of the device can slide. When calibrating a temperature transmitter, another temperature transmitter can be connected in advance. The connection line of the other temperature transmitter is plugged into the other two plug holes 23 of the sliding connection block 3. When the controller 5 completes a temperature calibration, the temperature transmitter can be connected to the other temperature transmitter in advance. After the detection and calibration of the transmitter, manually pinch the pressing block 12, and then retract the fixed card rod 13 from the fixed card hole 8 through the synchronization plate 10, and then slide the sliding connection block 3 inside the sliding groove 2. The other fixed card block 9 on the sliding connection block 3 is stuck in the other fixed card slot 7, and the fixed card rod 13 extends into the fixed card hole 8 for restriction. The contact protrusion 16 on the back of the sliding connection block 3 will also retract due to the spring 17 when sliding, until the other contact protrusion 16 on the sliding connection block 3 contacts the contact groove 15, completing the change of the calibration target. The whole process is simple and fast, without excessive downtime, ensuring the efficiency of detection and calibration.
[0029] Compared with related technologies, the temperature transmitter auxiliary calibration platform provided by the present invention has the following beneficial effects:
[0030] Traditional calibration stations require extended downtime when changing test targets. However, this patented system allows one temperature transmitter to be calibrated while another is being clamped and electrically connected. This significantly reduces equipment idle time and allows more calibrations to be completed within the same timeframe, accelerating production and improving overall efficiency. Furthermore, because the connection location of the socket 23 is dustproof, problems such as poor contact and unstable signal transmission caused by dust intrusion are reduced. This means that the service life of the socket 23 and related electrical components is extended, reducing the need for frequent component replacement due to dust damage.
