Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of boiler detection, in particular to a contact type boiler expansion online monitoring device and method thereof. BACKGROUND

[0002] The boiler will expand when in use, and the expansion amount should be within a certain range, otherwise there is a great safety hazard. The expansion amount of the boiler needs to be detected when in use.

[0003] For example, a boiler expansion indicator in Chinese patent CN222544682U includes an indicator box, a first distance sensor is arranged at the bottom of the indicator box, a second distance sensor is arranged at one side of the indicator box, a control panel is further arranged outside the indicator box, a connecting mechanism is installed at the top end of the indicator box, the connecting mechanism includes a connecting rod, the connecting rod is welded with the boiler, an adjusting frame is arranged at one end of the connecting rod, a sliding groove is arranged at one side of the adjusting frame, a sliding rod is sleeved in the sliding groove, a supporting rod is arranged outside the sliding groove, a telescopic rod is arranged at the bottom end of the supporting rod, a first positioning disc is arranged at the bottom end of the indicator box, and a second positioning disc is arranged at the top of the first positioning disc. The first distance sensor and the first positioning disc detect the height displacement during expansion, the second distance sensor and the second positioning disc detect the front and rear and left and right displacement during expansion, so as to judge the expansion of the boiler, and the intelligent sensing type expansion indication effect is achieved.

[0004] The above structure needs to ensure that the distance sensor and the corresponding positioning disc are in a direct opposite state to ensure the accuracy of the data. However, the boiler expands in three dimensions, and different expansion amounts in the three dimensions will cause the connecting rod to tilt. When tilted, the distance sensor cannot be directly opposite to the corresponding positioning disc. The distance sensor is in a tilted state compared to the corresponding positioning disc, and the measured data is not the shortest data, thereby causing a large detection error.

Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0039] The present application will be further described below in combination with the embodiments.

[0047] A calibration assembly 5 for accurate detection of the orthogonal detection assembly 8 is connected to the side wall of the horizontal adjusting assembly.

[0048] Before online boiler expansion monitoring, calibration component 5 performs accuracy testing on orthogonal detection component 8. If orthogonal detection component 8 passes the test, online expansion monitoring is performed; if it fails, online expansion monitoring is not performed. This avoids errors in the boiler expansion monitoring data due to inaccuracies in the detection accuracy of orthogonal detection component 8, ensuring that orthogonal detection component 8 meets the accuracy requirements before monitoring, thus guaranteeing the accuracy of the monitoring data. During online boiler expansion monitoring, boiler connecting plate 7 moves with the boiler expansion.

The orthogonal detection component 8 works with the Z-direction detection auxiliary plate 1, the Y-direction detection auxiliary plate 2, and the X-direction detection auxiliary plate 3 to monitor the current three-dimensional coordinate value of the orthogonal detection component 8. Then, the current three-dimensional coordinate value of the vertical automatic adjustment component is calculated based on the current three-dimensional coordinate value of the mounting base 82. The difference between the current three-dimensional coordinate value of the vertical automatic adjustment component and the initial three-dimensional coordinate value of the vertical automatic adjustment component is calculated. The difference is the expansion value of the boiler in the three-dimensional direction, which facilitates accurate and rapid monitoring of the boiler expansion value.

[0053] The Y-direction detection inductor 81, the Z-direction detection inductor 83 and the X-direction detection inductor 85 are all laser ranging sensors;

[0054] Before the boiler expansion on-line monitoring, the calibration assembly 5 is rotated to be opposite to the Y-direction detection inductor 81, the Z-direction detection inductor 83 and the X-direction detection inductor 85 of the orthogonal detection assembly 8, the Y-direction detection inductor 81, the Z-direction detection inductor 83 and the X-direction detection inductor 85 are started, the Y-direction detection inductor 81, the Z-direction detection inductor 83 and the X-direction detection inductor 85 monitor the distance value of the calibration assembly 5, and then the difference value is calculated with the initial distance value of the Y-direction detection inductor 81, the Z-direction detection inductor 83 and the X-direction detection inductor 85 to the calibration assembly 5, when the three groups of difference values are in conformity with the standard, the Y-direction detection inductor 81, the Z-direction detection inductor 83 and the X-direction detection inductor 85 are in the qualified state, then the orthogonal detection assembly 8 carries out the expansion on-line monitoring, when one group of difference values is not in conformity with the standard, the orthogonal detection assembly 8 is unqualified, the orthogonal detection assembly 8 does not carry out the expansion on-line monitoring, the data of the boiler expansion on-line monitoring is avoided to have errors due to the detection accuracy error of the orthogonal detection assembly 8, the orthogonal detection assembly 8 is ensured to be in the monitoring state under the condition of conforming to the detection accuracy requirement, and the monitoring data accuracy is ensured;

[0056] Calibration component 5 includes an L-shaped plate 51, a U-shaped plate 52, an electric push rod 53, a first rotating seat 54, a second rotating seat 55, and a third rotating seat 56.

The inner top end of the U-shaped plate 52 is connected to the second rotating seat. 55 is rotatably connected, and the second rotating seat 55 is fixedly connected to the end face of the connecting straight plate 67 away from the rotating motor 66. The second rotating seat 55 is located below the first rotating seat 54. The side wall of the U-shaped plate 52 is fixedly connected to the L-shaped plate 51. When the orthogonal detection component 8 performs monitoring, both the L-shaped plate 51 and the U-shaped plate 52 are set higher than the mounting base 82.

Under the action of the second rotating seat 55, the third rotating seat 56 drives the U-shaped plate 52 to rotate along the second rotating seat 55. The U-shaped plate 52 rotates downward until the U-shaped plate 52 is directly opposite the Y-direction detection sensor 81 and the Z-direction detection sensor 83, and the L-shaped plate 51 is directly opposite the X-direction detection sensor 85. The Y-direction detection sensor 81 and the Z-direction detection sensor 83 detect the distance values ​​from the Y-direction detection sensor 81 and the Z-direction detection sensor 83 to the U-shaped plate 52. The X-direction detection sensor 85 detects the distance value from the X-direction detection sensor 85 to the L-shaped plate 51, and then compares it with the Y-direction detection sensor 85. The initial distance values ​​from the detection sensors 81, Z-axis detection sensor 83, and X-axis detection sensor 85 to the calibration component 5 are used to calculate the error rate. When all three error rates meet the standard, the Y-axis detection sensors 81, Z-axis detection sensors 83, and X-axis detection sensors 85 are in a qualified state. Then, the orthogonal detection component 8 performs online expansion monitoring. When one error rate does not meet the standard, the orthogonal detection component 8 is in an unqualified state and does not perform online expansion monitoring. This avoids errors in the boiler expansion online monitoring data caused by errors in the detection accuracy of the orthogonal detection component 8, ensuring that the orthogonal detection component 8 enters the monitoring field under the condition of meeting the detection accuracy requirements, and ensuring the accuracy of the monitoring data.

[0059] When the Y-direction detection sensor 81, the Z-direction detection sensor 83 and the X-direction detection sensor 85 are all qualified, the electric push rod 53 of the calibration assembly 5 pushes the third rotating seat 56 to move downward, and the third rotating seat 56 drives the U-shaped plate 52 to rotate along the second rotating seat 55 under the action of the second rotating seat 55, and the U-shaped plate 52 rotates downward, and the L-shaped plate 51 and the U-shaped plate 52 are higher than the mounting seat 82, so as to avoid affecting the online monitoring of the boiler expansion by the Y-direction detection sensor 81, the Z-direction detection sensor 83 and the X-direction detection sensor 85.
