Description

Technical Field

[0002] With the increase in the capacity of steam turbine units, the safety monitoring and protection of steam turbines have become an important part of the operation of steam turbines. At the same time, higher requirements are put forward for the accuracy and reliability of the actions of various safety devices of steam turbines. The safety detection system of steam turbines monitors the rotational speed, bearing vibration, axial displacement, differential expansion between high and low pressure cylinders, cover vibration, eccentricity, and absolute expansion of the steam turbine in real time. When a certain parameter exceeds the limit, the TSI (Safety Monitoring and Protection System) timely issues an alarm or trip signal to protect the safe operation of the steam turbine equipment. The most important part in the TSI monitoring system is the TSI probe.

[0003] After installing the TSI probe, it is necessary to calibrate the TSI probe to ensure that the angle and height of the TSI probe are in appropriate positions, so as to ensure that the TSI probe can accurately perform the monitoring work. In the related art, when performing the calibration work, the inclination angle of the TSI probe is generally measured manually. This calibration method requires manual calibration work multiple times, which makes the entire calibration process time-consuming and reduces the calibration efficiency. Therefore, a calibration device for steam turbine TSI probes is needed to solve the above problems. Summary of the Invention

[0030] Advantageous effects: Through the cooperation of the motor and the electric push rod, the height and angle of the contact plate can be accurately adjusted to ensure that the probe is calibrated to a preset angle, improving the accuracy of measurement or operation. By controlling the motor and the electric push rod through switches, the adjustment process is simplified, the complexity and error of manual operation are reduced, and the efficiency is improved. Combining the dual adjustment functions of height and angle can meet various calibration requirements and is applicable to probe calibration in different scenarios. By observing the angle degree in real time through the angle indicator plate, it is convenient to quickly adjust and reach the preset value, improving the intuitiveness and controllability of the operation.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0046] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "connected" should be understood in a broad sense.

[0047] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0048] With the continuous increase in the capacity of steam turbine units, the turbine safety monitoring and protection system (TSI) plays an increasingly important role in ensuring the safe operation of equipment. The TSI system ensures the operation of the unit within a safe range by real-time monitoring of key parameters of the steam turbine, such as rotational speed, bearing vibration, axial displacement, differential expansion between high and low pressure cylinders, cover vibration, eccentricity, absolute expansion, etc. When a certain parameter exceeds the set limit, the TSI system will promptly issue an alarm or trip signal to prevent equipment damage or accidents.

[0049] In the TSI system, the installation and calibration of the probe are key steps to ensure the accuracy and reliability of the monitoring data. The TSI probe is used to measure parameters such as vibration and displacement of various key parts of the steam turbine. Its installation angle and height must be precise to ensure the accuracy of the monitoring data. Traditional calibration methods usually rely on manual operation. Technicians need to manually measure the tilt angle and installation height of the probe using measuring tools and make multiple adjustments and calibrations. This method is not only time-consuming but also easily affected by human errors, resulting in low calibration efficiency and even potentially affecting the accuracy of the monitoring data.

[0050] The present invention provides a probe calibration device and method to solve the problem of poor accuracy in manual operation of probe calibration.

[0051] The following combines Figures 1 to 5 , to describe the embodiments of the present invention.

[0052] According to an embodiment of the present invention, on the one hand, a probe calibration device is provided, including: a base 1; a height component 2 disposed on the base 1, the height component 2 including a moving frame 27, the moving frame 27 being adapted to approach or move away from the base 1 along a first direction; a contact plate 4 adapted to contact at least one side surface of the probe, the contact plate 4 and the moving frame 27 being hingedly connected; an angle component 3 respectively connected to the contact plate 4 and the moving frame 27, the angle component 3 being adapted to adjust the angle between the contact plate 4 and the plane where the moving frame 27 is located; a protractor mechanism 5 disposed at the rotational connection between the contact plate 4 and the moving frame 27, adapted to measure the included angle between the contact plate 4 and the moving frame 27; the first direction is not parallel to the plane where the base 1 is located.

The settings of the height component 2 and the angle component 3 are beneficial to calibrating the probe from two aspects of height and angle, improving the calibration accuracy, and at the same time making the structure simple and the installation convenient. The protractor mechanism 5 can improve the calibration accuracy and calibrate the probe by measuring the angle of the contact plate 4 relative to the plane where the moving frame 27 is located. The protractor mechanism 5 is disposed at the rotational connection between the contact plate 4 and the moving frame 27, making the structure simple and the angle intuitive. The first direction is not parallel to the plane where the base 1 is located.

[0054] Further, an anti-slip pad 11 is provided on one side of the base 1 away from the height component 2. The anti-slip pad 11 increases the friction between the base 1 and the contact surface, effectively preventing the device from sliding or shifting, and improving the overall stability.

[0055] As a form of implementation, the first direction is perpendicular to the plane where the base 1 is located. The base 1 is horizontally placed on the workbench. A storage battery 14 is provided on the surface of the workbench for providing power to the device, and a first switch 12 and a second switch 13 are also provided for controlling the height component 2 and the angle component 3.

[0056] In some embodiments, in combination with Figure 1As shown, the height component 2 further includes a hollow rod 25 and a sliding rod 26. The hollow rod 25 and the sliding rod 26 are inserted and slidably engaged with each other in the first direction to form a sliding rod mechanism. One end of the sliding rod mechanism is connected to the base 1, and the other end is connected to the moving frame 27.

[0057] The sliding rod mechanism formed by the insertion and sliding engagement of the hollow rod 25 and the sliding rod 26 in the height component 2 has a simple structure, which is convenient for installation and disassembly. At the same time, it reduces the maintenance cost. The sliding rod mechanism allows sliding in the first direction, can flexibly adjust the height according to needs, and adapts to different application requirements. One end of the sliding rod mechanism is connected to the base 1, and the other end is connected to the moving frame 27, ensuring the stability of the overall structure and preventing shaking or tilting.

[0058] Furthermore, the sliding rod structures are respectively arranged at the four corners of the quadrilateral base 1 to maintain the stable movement of the moving frame 27 along the first direction. The moving frame 27 is connected to the sliding rod mechanism, and the connection points are respectively located at the four corners of the quadrilateral moving frame 27.

[0059] As an implementation form, the sliding rod mechanism can be set as a hydraulic rod, which can provide power for the height component 2 while maintaining stable movement.

[0060] In some embodiments, as Figure 1 shown, the angle component 3 further includes: a first hinge seat 33, which is slidably connected to the support rod 28; a second hinge seat 37, which is fixedly connected to the contact plate 4; and a connecting rod 34, the two ends of which are respectively hinged to the first hinge seat 33 and the second hinge seat 37.

[0061] The first hinge seat 33 is slidably connected to the support rod 28, the second hinge seat 37 is fixedly connected to the contact plate 4, and the two ends of the connecting rod 34 are respectively hinged to the two hinge seats, making the angle adjustment more flexible and capable of meeting different angle requirements. The hinge design of the hinge seats and the connecting rod 34 ensures the stability of the structure, can remain firm after adjusting the angle, and avoids loosening or deviation. The structures of the hinge seats and the connecting rod 34 are simple, convenient for installation and disassembly, and also convenient for daily maintenance and repair.

[0062] In some embodiments, as Figure 1 shown, the protractor mechanism 5 includes: a through hole 36, which is opened at the rotation connection axis of the moving frame 27 and the contact plate 4; and a rotating shaft 53, which is inserted through the through hole 36, and the rotating shaft 53 is fixedly connected to the contact plate 4.

[0063] The through hole 36 is opened at the axis where the moving frame 27 is rotatably connected to the contact plate 4. The rotating shaft 53 passes through the through hole 36 and is fixedly connected to the contact plate 4, ensuring the stability of the rotation of the contact plate 4 around the axis, realizing accurate angle measurement, being convenient for installation, and reducing the installation and maintenance costs. The rotating shaft 53 is fixedly connected to the contact plate 4, ensuring that the contact plate 4 will not shift or shake during rotation, improving the stability and reliability of measurement. Through the cooperation of the rotating shaft 53 and the through hole 36, the contact plate 4 can quickly and accurately rotate to the target angle, improving the efficiency of angle measurement.

[0064] Further, one end of the contact plate 4 and the moving frame 27 are rotatably connected through the through hole 36 and the rotating shaft 53. The second hinge seat 37 is arranged on the side of the contact plate 4 away from the through hole 36. By the displacement of the first hinge seat 33 along the support rod 28, the connecting rod 34 and the second hinge seat 37 hinged to the connecting rod 34 are driven, so that the contact plate 4 rotates around the through hole 36.

[0065] In some embodiments, as shown in Figure 3 the angle measuring mechanism 5 further includes: an angle indicating plate 51, arranged at at least one opening end of the through hole 36, and the center of the outer arc of the angle indicating plate 51 intersects with the axis line of the through hole 36; a pointer 52, arranged at at least one end of the rotating shaft 53, and the length direction of the pointer 52 is not parallel to the axis of the rotating shaft 53.

[0066] The combination of the angle indicating plate 51 and the pointer 52 can intuitively display the rotation angle of the contact plate 4, facilitating the operator to quickly read the measurement result. The center of the outer arc of the angle indicating plate 51 intersects with the axis line of the through hole 36, ensuring the accuracy of the angle scale. Combined with the non-parallel setting of the pointer 52, high-precision angle measurement can be realized. The length direction of the pointer 52 is not parallel to the axis of the rotating shaft 53, so that the pointer 52 can clearly point to the scale on the angle indicating plate 51, improving the practicability of the mechanism.

[0067] Further, the length direction of the pointer 52 is perpendicular to the axis of the rotating shaft 53, which can make the pointer 52 point to clearly show the angle reading.

[0068] In some embodiments, as shown in Figure 2 the height component 2 includes a lead screw 22 arranged along the first direction, and the angle component 3 includes a nut 32. The lead screw 22 is in mating connection with the nut 32. The mating connection of the lead screw 22 and the nut 32 can realize precise adjustment in the height direction. By rotating the lead screw 22, the position of the moving frame 27 or the contact plate 4 can be precisely controlled to meet the high-precision requirements. The thread fit of the lead screw 22 and the nut 32 has a certain self-locking property, and can automatically maintain the position after being adjusted to the target height without an additional locking device. The cooperation of the lead screw 22 and the nut 32 can quickly and accurately realize height adjustment, improving the working efficiency.

[0069] Further, the height component 2 further includes: a moving seat 35, the moving seat 35 is connected to the nut 32; a support rod 28, one end of the support rod 28 abuts against the moving frame 27, and the other end is connected to the moving seat 35. The moving seat 35 is connected to the nut 32, facilitating height adjustment to meet different requirements. One end of the support rod 28 abuts against the moving frame 27, and the other end is connected to the moving seat 35, ensuring the structural stability.

[0070] Further, the height component 2 is driven by a motor 21, and the motor 21 is respectively connected to the base 1 and the lead screw 22; the angle component 3 is driven by an electric push rod 31, the electric push rod 31 extends along a first direction, and the electric push rod 31 is respectively connected to the first hinge seat 33 and the moving seat 35. The moving seat 35 is fixedly connected to the nut 32.

[0071] The motor 21 drives the height component 2, and the electric push rod 31 drives the angle component 3 to achieve automatic adjustment of the height and angle, improving the operation convenience. The motor 21 is connected to the base 1 and the lead screw 22, the electric push rod 31 is connected to the first hinge seat 33 and the moving seat 35, and the moving seat 35 is fixed to the nut 32, making the overall structure stable and reliable.

[0072] Specifically, the electric push rod 31 is disposed on the moving seat 35 along the first direction and acts on the first hinge seat 33 to displace the first hinge seat 33 along the first direction, thereby realizing the rotation of the contact plate 4.

[0073] According to an embodiment of the present invention, on the other hand, a probe calibration method is further provided, including the above-mentioned probe calibration device, and further including: starting the motor 21 by controlling the first switch 12, the lead screw 22 and the nut 32 drive the angle component 3 to rise, so that the contact plate 4 rises until the bottom end of the probe abuts against the contact plate 4; starting the electric push rod 31 by controlling the second switch 13, so that the contact plate 4 rotates around the axis of the rotating shaft 53 until the contact plate 4 fits against the outer surface of the probe; observing the degree of the angle indicating plate, and adjusting the rotation and lifting of the contact plate 4 multiple times through the electric push rod 31 and the motor 21, so as to adjust the angle degree to a preset degree, thereby calibrating the probe to an appropriate angle.

[0074] Through the cooperation of the motor 21 and the electric push rod 31, the height and angle of the contact plate 4 can be precisely adjusted to ensure that the probe is calibrated to the preset angle, improving the accuracy of measurement or operation. By controlling the motor 21 and the electric push rod 31 with a switch, the adjustment process is simplified, reducing the complexity and error of manual operation and enhancing the efficiency. Combining the dual adjustment functions of height and angle can meet various calibration requirements and is applicable to probe calibration in different scenarios. By observing the angle degree in real time through the angle indicator board, it is convenient to quickly adjust and reach the preset value, enhancing the intuitiveness and controllability of the operation. The automatic adjustment of the motor 21 and the electric push rod 31 reduces manual intervention, lowers the operation difficulty, and at the same time improves the efficiency and consistency of calibration. This method provides steps for manual operation, making the operation process-based and standardized.
