The burner test system of the present invention realizes accurate detection of the actual processing size of the burner, effectively improves the factory qualification rate of the burner, reduces production losses, improves the stability and reliability of the quartz glass preparation process, and provides a guarantee for the standardized production of synthetic quartz glass and the acceptance assessment of the burner. In this specific embodiment, water is used as the test liquid, which is convenient for observation and saves test costs. In practical applications, other types of test liquids can also be used, but care should be taken to avoid corrosion of the burner 2 to be tested and other parts of the system.

[0048] The cabinet 1 includes a support frame and a plate connected to the support frame, and the plate forms the top wall, side wall and bottom plate of the cabinet 1. A drain is provided on the bottom plate of the cabinet 1 to facilitate the discharge of the test liquid.

After adjusting the angle, the locking element is used to lock it to ensure the structural stability of the burner 2 to be tested during the test and to ensure the test accuracy.

[0050] In other specific embodiments that can be realized by the present invention, the support rod 15 is threadedly connected to the clamping hoop 16 to facilitate adjustment of the angle between the two. In practical applications, the clamping hoop 16 can be set as a split structure to facilitate operation and fixation of the burner 2 to be tested, and the clamping hoop 16 and the support rod 15 are detachably connected to facilitate selection of clamping hoops 16 of different specifications according to different test requirements, thereby improving the flexibility and adaptability of the fixing rotating mechanism 3.

[0051] In addition, in order to provide effective protection for the burner 2 to be tested, a flexible protective layer is provided on the side of the clamping hoop 16 that contacts the burner 2 to be tested. The flexible protective layer can be made of an elastic material to ensure stable clamping of the burner 2 to be tested while preventing the clamping hoop 16 from causing damage to the burner 2 to be tested, thereby ensuring the quality of the burner.

[0052] More specifically, the pressurizing mechanism 6 includes a test pipeline, one end of which is connected to an external test liquid source, and the other end of the test pipeline passes through the cabinet 1 and is connected to the wick tube of the burner 2 to be tested. The test pipeline can also adopt a segmented structure to meet the connectivity requirements. A control valve 18 is provided on the test pipeline, and the control valve 18 is provided on the cabinet 1. The control valve 18 can adjust the test liquid pressure in the test pipeline to meet different test requirements and ensure the working reliability of the burner test system.

The number of test pipelines can be adjusted according to the type of burner 2 to be tested to meet the testing requirements of different types of burners.

[0054] In this specific embodiment, the measuring platform 5 is connected to the inner wall of the cabinet 1 by sliding using the lifting module 4, thereby improving the convenience of adjusting the position of the measuring platform 5. The lifting module 4 includes a mounting bracket 13, which is slidably connected to the inner wall of the cabinet 1, and the sliding direction of the mounting bracket 13 is parallel to the vertical direction, so as to adjust the distance between the burner 2 to be tested and the measuring platform 5; the measuring platform 5 is slidably connected to the mounting bracket 13, and the relative sliding direction between the measuring platform 5 and the mounting bracket 13 is parallel to the horizontal direction, so that the measuring scale 14 can be directly opposite to the burner 2 to be tested; the mounting bracket 13 reciprocates in the vertical direction relative to the cabinet 1 to adjust the vertical position of the measuring platform 5, and the measuring platform 5 slides relative to the mounting bracket 13 to adjust the horizontal position of the measuring platform 5, so that the distance between the measuring platform 5 and the burner 2 to be tested meets the test requirements, and at the same time, the nozzle of the burner 2 to be tested is directly opposite to the measuring scale 14. In order to improve the structural stability of the lifting module 4, locking elements 11 are provided between the mounting bracket 13 and the cabinet 1, and between the measuring platform 5 and the mounting. After the position is adjusted, the mounting bracket 13 and the measuring platform 5 are locked to facilitate observation by the test personnel.

[0055] It is also necessary to explain here that during the test, the distance between the measuring platform 5 and the burner 2 to be tested, as well as the pressure of the test liquid, can be determined according to different types of burners 2 to be tested. Reasonable setting of test parameters and evaluation of the burner 2 to be tested based on the test structure are common practices of those skilled in the art and will not be repeated here.

[0056] In order to improve the position adjustment accuracy of the lifting module 4, the lifting module 4 also includes a lifting rail 9, which is connected to the inner wall of the cabinet 1, and has a lifting slot. The mounting bracket 13 has a lifting slider matched with the lifting slot, and the lifting slider is slidably arranged in the lifting slot to improve the reciprocating sliding accuracy of the mounting bracket 13; in practical applications, the lifting slider and the lifting slot can be selected as a dovetail structure, while ensuring the reciprocating motion accuracy, to prevent the lifting slider from coming out, and improve the movement safety of the lifting module 4. Correspondingly, the mounting bracket 13 also has an adjustment hole 17, and the bottom of the measuring platform 5 has an adjustment column 12 that matches the adjustment hole 17, and the adjustment column 12 can slide through the adjustment hole 17. In this specific embodiment, the adjustment hole 17 is a long hole parallel to the left and right direction of the cabinet 1, which is convenient for adjusting the left and right position of the measuring platform 5; in practical applications, the direction of the adjustment hole 17 can also be set according to actual adjustment requirements. The locking element 11 can fix the relative position of the lifting rail 9 and the adjustment column 12 and the mounting bracket 13.

[0057] In order to facilitate monitoring the position of the measuring platform 5, a scale is provided on the lifting rail 9. In the process of adjusting the measuring platform 5, it is also convenient for the tester to easily obtain the distance between the burner nozzle and the measuring platform 5, thereby improving the testing convenience of the system. In this specific embodiment, the mounting bracket 13 is an L-shaped structure with a stable structure. A level bubble 10 for assisting leveling is also provided on the mounting bracket 13, which is conducive to further improving the position adjustment accuracy of the measuring platform 5.

[0058] Among them, there are two groups of lifting modules 4, and the two groups of lifting modules 4 are symmetrically arranged with the center line of the measuring platform 5 as the axis, which improves the force uniformity of the measuring platform 5, thereby ensuring the structural stability of the measuring platform 5 during the test, which is conducive to improving the test accuracy.

[0059] In this specific embodiment, the image acquisition element 7 is a camera, which is detachably connected to the cabinet 1 for easy disassembly and maintenance. The image acquisition element 7 can communicate with the PC and the external image processing module 8 to export the captured image for analysis.

[0074] After acquiring the burner nozzle wick tube image, the image is processed as follows:

[0075] The image is edge filtered and grayscale processed. The cv.pyrMeanShiftFiltering image processing algorithm is used for edge filtering to effectively remove noise and smooth the image of the burner nozzle wick tube, while retaining the edge and detail information of the image.

[0076] Based on machine learning, using the Hough gradient method of OpenCV, the center and radius of the circle are detected through the accumulator, the size of the circular structure such as the wick tube and the external lampshade in the image is identified, and the actual length corresponding to each pixel is calculated according to the scale to obtain the radius of each identified wick tube;
