This application mounts a visual inspection mechanism on a ring. Through the meshing of an external gear ring and a first gear, a first servo motor drives the visual inspection mechanism to perform a circumferential visual inspection operation around the ignition point.

Description

Technical Field

[0001] This application relates to the field of flame visual inspection technology, and in particular to a flame morphology visual inspection device and method. Background Technology

[0002] With the improvement of industrial automation and the enhancement of fire safety awareness, visual detection and analysis of flame patterns have broad application prospects in many fields. By detecting and analyzing the flame pattern at the ignition point, we can understand important characteristics such as the flame ignition, development stage and combustion state. Accurate detection and analysis can provide key basis for early fire warning, combustion efficiency optimization and accident cause tracing.

[0003] Most existing flame morphology visual detection devices rely on a single camera or a fixed-position visual sensor for detection. They can only capture and analyze the flame morphology at the ignition point from a single perspective. This single-position detection method results in a serious lack of detection information and cannot fully present the three-dimensional morphology, dynamic changes, and interaction characteristics of the flame with the surrounding environment in space. Single-view detection is prone to missing key information such as the lateral spread of the flame and the characteristics of bottom combustion, resulting in incomplete flame morphology visual detection and analysis results and also easily affecting the accuracy of its detection structure.

[0004] To address these issues, a flame shape visual detection device is proposed to solve some of the problems existing in the prior art. Summary of the Invention

[0005] The purpose of this application is to improve the diversity of viewing angles during flame pattern visual inspection, thereby improving the accuracy and comprehensiveness of the inspection results. Compared with the prior art, it provides a flame pattern visual inspection device, including a frame, a fireproof ring plate fixed inside the frame, and a circular ring rotatably sleeved on the upper outer side of the fireproof ring plate. An external toothed ring is fixed around the outer side of the circular ring. A shell is fixed on the frame, and a first servo motor is fixed inside the shell. A first gear meshing with the external toothed ring is fixed on the drive shaft of the first servo motor. A visual inspection mechanism is installed on the circular ring, and the visual inspection mechanism includes a vertical cylinder mounted vertically on the circular ring. A protective shell is fixed at the top of the vertical cylinder. A first annular glass is fixed inside the protective shell, and a second annular glass is sleeved outside the first annular glass. A vertically arranged detector body is rotatably installed inside the vertical cylinder, and the upper end of the detector body extends into the first annular glass. A visual probe located inside the first annular glass is fixed on the detector body. A second servo motor is fixed at the bottom of the circular ring, and the drive shaft of the second servo motor is connected to the bottom end of the detector body.

[0006] Furthermore, the height of the second annular glass is set to four times the height of the first annular glass. Protective plates symmetrically arranged on the upper and lower sides of the first and second annular glass are fixed inside the protective shell, and the protective plates are set in a funnel shape. The first and second annular glass, together with the protective plates, form a chamber. A water pump and a liquid storage tank are fixed inside the outer shell.

[0007] Furthermore, the vertical cylinder is provided with a water supply channel and a water return channel that communicate with the chamber. An inner ring frame is fixed on the ring and is coaxially arranged therewith. An outer ring frame is fixed on the outer shell and is slidably sleeved on the outside of the inner ring frame. A first annular channel and a second annular channel are sequentially opened on the mating surfaces of the inner ring frame and the outer ring frame. The outlet of the water pump is connected to the inside of the first annular channel from one side of the outer ring frame.

[0008] Furthermore, airflow channels are provided around the upper and lower end walls of the protective shell, and nozzles communicating with the airflow channels are provided at the upper and lower edges of the protective shell. An air pump is fixed inside the shell, and a third annular channel is provided on the mating surface of the inner and outer ring frames.

[0009] Furthermore, the vertical cylinder is rotatably connected to the circular ring, a second gear is fixed on the vertical cylinder, and an internal gear ring coaxially arranged with the fireproof ring plate is fixed on the outer shell. The second gear meshes with the inner side of the internal gear ring, and a high-temperature resistant brush adapted to the second annular glass is fixed on the inner ring frame.

[0010] Furthermore, a first ring box and a second ring box are fixed on the ring and rotatably sleeved on the outside of the vertical cylinder. A first through hole is opened on the end wall of the vertical cylinder, connecting the water supply channel and the first ring box, and a second through hole is opened, connecting the water return channel and the second ring box. The first ring box is connected to the inside of the first annular channel from the inner ring frame side, and the second ring box is connected to the inside of the second annular channel from the inner ring frame side. A third ring box is fixed on the first ring box and rotatably sleeved on the outside of the vertical cylinder. An outer sleeve is fixed on the outside of the vertical cylinder and rotatably connected to the third ring box. The outer sleeve is connected to the inner wall of the airflow channel. The third ring box is connected to the inside of the third annular channel from the inner ring frame side, and the air pump is connected to the inside of the third annular channel from the outer ring frame side.

[0011] Furthermore, there are multiple liquid storage tanks, each containing a different color of coolant. Two pipe switching mechanisms are fixed inside the outer casing. One pipe switching mechanism connects the multiple liquid storage tanks to the water pump inlet, while the other pipe switching mechanism connects the second annular channel and the multiple liquid storage tanks from one side of the outer ring frame.

[0012] Furthermore, the tube switching mechanism includes a circular box fixed inside the outer shell, and a plurality of first connecting tubes arranged in a ring are fixedly connected to the cylindrical surface of the circular box. A cylinder adapted to its internal size is rotatable inside the circular box, and a third through hole is opened on the cylindrical surface of the cylinder. A third servo motor for driving the cylinder to rotate is fixed on the outside of the circular box, and a second connecting tube communicating with the inside of the cylinder is provided on the side of the circular box away from the third servo motor.

[0013] Furthermore, a third connecting pipe is fixed on the cylindrical surface of the round box and disposed between two adjacent first connecting pipes.

[0014] Furthermore, a visual detection method for flame shape includes the following steps:

[0015] S1. Drive the detector body to rotate by the second servo motor, adjust the orientation of the vision probe, so that the vision probe points through the first and second annular glass to the ignition point inside the fireproof ring plate, and visually collects the flame pattern of the ignition point.

[0016] S2. The first servo motor drives the ring to rotate continuously, so that the vision probe moves around the ignition point. Simultaneously, the rotation of the second servo motor drives the orientation of the vision probe to be continuously adjusted so that the vision probe always visually captures the flame shape of the ignition point during the circling motion.

[0017] S3. During the visual inspection process, the water pump is powered on and started. In conjunction with the pipe switching mechanism, the coolant stored in different liquid storage tanks is delivered to the chamber between the first and second annular glass according to the requirements. The visual probe completes the physical filter operation during visual inspection through the coolant of different colors in the chamber, and performs visual inspection of the flame shape under different filters.

[0018] Compared to existing technologies, the advantages of this application are:

[0019] (1) This application installs the visual inspection mechanism on a ring. By means of the meshing of the external gear ring and the first gear, the first servo motor can drive the visual inspection mechanism to perform a circumferential visual inspection operation around the ignition point. At the same time, by rotating the detector body inside the vertical cylinder and fixing a second servo motor at the bottom of the ring to drive the detector body to rotate, the device can drive the detector body to rotate and adjust the visual probe when the visual inspection mechanism is running around, so that the visual probe always faces the ignition point to perform visual inspection of the flame shape. With the cooperation of both, it can not only effectively improve the comprehensiveness of the visual inspection of the flame shape, but also effectively improve the accuracy and stability of the inspection process.

[0020] (2) By protecting the visual probe with a first and second annular glass on the outside and forming a chamber with symmetrically arranged protective plates, and by circulating coolant into the chamber with the help of a water pump and a liquid storage tank, the visual probe can be prevented from working in an overheated environment. This allows the visual detection mechanism to be closer to the ignition point for detection, which in turn improves the accuracy of the device in detecting the flame shape at the ignition point. At the same time, by setting up multiple liquid storage tanks to store coolant of different colors and setting up a pipe switching mechanism to switch the coolant delivery, the color of the coolant flowing through the chamber can be continuously adjusted during the operation of the device. This achieves a filter for the image captured by the visual probe at the physical level. Visual detection of the flame shape under different filters can effectively improve the comprehensiveness of the detection, which in turn improves the accuracy of the detection.

[0021] (3) By opening the nozzles connected to the airflow channel at the upper and lower edges of the protective shell and using an air pump to deliver airflow, a high-speed airflow layer can be formed on the outer surface of the second annular glass, reducing the probability of dust and impurities adhering to the outer surface of the second annular glass. At the same time, by rotating the vertical cylinder on the ring and fixing a second gear on the vertical cylinder that meshes with the inner gear ring, the ring can drive the vertical cylinder to rotate relative to the high-temperature resistant brush fixed on the inner ring frame during the rotation of the visual inspection mechanism. The high-temperature resistant brush wipes the outer surface of the second annular glass. With the help of the wiping of the high-temperature resistant brush and the air curtain formed by the jet airflow in the nozzle, the cleanliness of the outer surface of the second annular glass can be effectively guaranteed.

[0036] The embodiments will be described clearly and completely with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments in this application without creative effort are within the scope of protection of this application.

[0037] Example 1:

[0038] This invention provides a flame shape visual detection device; please refer to [link / reference]. Figures 1-12As shown, the system includes a frame 1, within which a fireproof ring plate 101 is fixed. A circular ring 102 is rotatably sleeved on the upper outer side of the fireproof ring plate 101. An external toothed ring 103 is fixed around the outer side of the circular ring 102. A housing 104 is fixed to the frame 1, and a first servo motor 105 is fixed inside the housing 104. A first gear 106, meshing with the external toothed ring 103, is fixed to the drive shaft of the first servo motor 105. A vision inspection mechanism is mounted on the circular ring 102, and the vision inspection mechanism includes a vertical cylinder 2 vertically mounted on the circular ring 102, with the top of the vertical cylinder 2... A protective shell 201 is fixed, and a first annular glass 202 is fixed inside the protective shell 201. A second annular glass 203 is sleeved outside the first annular glass 202. A vertically arranged detector body 205 is rotatably installed inside the vertical cylinder 2, and the upper end of the detector body 205 extends into the first annular glass 202. A vision probe 206 located inside the first annular glass 202 is fixed on the detector body 205. A second servo motor 207 is fixed at the bottom of the ring 102, and the drive shaft of the second servo motor 207 is connected to the bottom end of the detector body 205.

[0039] During operation, the ignition point of the flame to be detected is set at any position within the fireproof ring plate 101. Once the flame ignites, the vision probe 206 mounted on the detector body 205 faces the ignition point and captures images of the flame pattern, thus achieving visual detection of the flame pattern. During detection, the second servo motor 207 is powered on and starts, driving the detector body 205, connected to its drive shaft, to rotate. This rotation of the detector body 205 ensures that the vision probe 206 faces the direction of the ignition point. In this state, the visual probe 206 is closest to the flame at the ignition point. Then, the first servo motor 105 is powered on and starts, driving the first gear 106 fixed on its drive shaft to rotate. Through the meshing of the first gear 106 and the external gear ring 103, the ring 102 is driven to rotate around the fireproof ring plate 101. During the rotation of the ring 102, the visual inspection mechanism installed on it can be driven to move around the ignition point, thereby enabling the visual probe 206 to rotate around the ignition point and perform visual inspection of the flame shape of the ignition point in an all-round surround pattern.

[0040] During the visual detection of the flame pattern around the ignition point, as the visual probe 206 moves around the fireproof ring plate 101, data analysis is performed through visual acquisition. The actual distance between the visual probe 206 and the ignition point, as well as the straight-line angle between the visual probe 206 and the ignition point, are calculated in real time. Then, the second servo motor 207 is started to adjust the orientation of the visual probe 206 on the detector body 205 in real time, so that the visual probe 206 always shines directly on the flame at the ignition point, and performs more accurate visual acquisition and detection of the flame at the ignition point.

[0041] During operation, the device mounts the visual inspection mechanism on the ring 102. Through the meshing of the external gear ring 103 and the first gear 106, the first servo motor 105 drives the visual inspection mechanism to perform a circumferential visual inspection operation around the ignition point. Simultaneously, by rotatably mounting the detector body 205 inside the vertical cylinder 2, and fixing a second servo motor 207 at the bottom of the ring 102 to drive the rotation of the detector body 205, the device can drive the detector body 205 to rotate and adjust the visual probe 206 as the visual inspection mechanism rotates. This ensures that the visual probe 206 always faces the ignition point to perform visual inspection of the flame shape. With this combination, not only can the comprehensiveness of the visual inspection of the flame shape be effectively improved, but also the accuracy and stability of the inspection process can be effectively enhanced.

[0042] Please see Figure 7 As shown, the height of the second annular glass 203 is set to four times the height of the first annular glass 202. Protective plates 204, symmetrically arranged on the upper and lower sides of the first annular glass 202 and the second annular glass 203, are fixed inside the protective shell 201. The protective plates 204 are funnel-shaped. The first annular glass 202 and the second annular glass 203, together with the protective plates 204, form a chamber. A water pump 3 and a liquid storage tank 301 are fixed inside the outer shell 104. During operation, the first annular glass 202 and the second annular glass 203, installed inside the protective shell 201 and fitted onto the outside of the vision probe 206, can provide stable protection for the vision probe 206. The two protective plates 204, symmetrically fixed on the upper and lower sides of the first annular glass 202 and the second annular glass 203, can guide the shooting angle of the vision probe 206 in acquiring flame patterns, which helps reduce the impact on the acquisition of flame patterns by the vision probe 206 and improves the anti-interference capability of flame pattern visual detection to a certain extent.

[0043] Furthermore, during the detection process, the water pump 3 is powered on and started. Through the pumping of the water pump 3, the coolant stored in the storage tank 301 can be transported to the cavity formed by the first annular glass 202, the second annular glass 203 and the protective plate 204. After the coolant flows in the cavity, it will carry away the heat that invades the vision probe 206 from the outside. Each storage tank 301 is equipped with a heat exchanger. The heat absorbed by the coolant is released to the outside at the heat exchanger. In this cycle, the vision probe 206 can be prevented from working in an overheated environment. The above-mentioned structural settings allow the vision detection mechanism to be closer to the ignition point for detection operations, which in turn helps to improve the accuracy of the device in detecting the flame pattern of the ignition point.

[0044] Please see Figure 7 and Figure 10As shown, the vertical cylinder 2 is provided with a water supply channel 302 and a water return channel 303 that communicate with the chamber. An inner ring frame 304 is fixed on the ring 102 and is coaxially arranged therewith. An outer ring frame 305 is fixed on the outer shell 104 and is slidably sleeved on the outside of the inner ring frame 304. A first annular channel 306 and a second annular channel 307 are sequentially opened on the mating surfaces of the inner ring frame 304 and the outer ring frame 305. The outlet of the water pump 3 is connected to the inside of the first annular channel 306 from one side of the outer ring frame 305.

[0045] During operation, as the device drives the coolant to circulate between the storage tank 301 and the chamber, the coolant in the storage tank 301, under the delivery of the water pump 3, enters the first annular channel 306 through the outer ring frame 305, then connects to the water supply channel 302 through the inner ring frame 304, enters the chamber, and then enters the second annular channel 307 through the return water channel 303 from the inner ring frame 304. It then flows back to the storage tank 301 through the outer ring frame 305. By fixing the inner ring frame 304 to the ring 102 and the outer ring frame 305 to the outer shell 104, and by surrounding the mating surfaces of the inner ring frame 304 and the outer ring frame 305 with the relative rotation of the inner ring frame 304 and the outer ring frame 305, the visual inspection mechanism does not interfere with the circulation of the coolant during its rotation around the fireproof ring plate 101, thus ensuring the stability of the device during operation.

[0046] Please see Figure 2 , Figure 7 and Figure 8As shown, airflow channels 4 are arranged around the upper and lower end walls of the protective shell 201. Spray holes 401 communicating with the airflow channels 4 are located at the upper and lower edges of the protective shell 201. An air pump 402 is fixed inside the outer shell 104. A third annular channel 403 is also provided on the mating surface of the inner ring frame 304 and the outer ring frame 305. During operation, the air pump 402 is powered on and starts, pumping airflow from the outer ring frame 305 side to the third annular channel 403, and then from the inner ring frame 304 side to the airflow channels 4. The airflow is then ejected through the spray holes 401 located at the upper and lower edges of the protective shell 201, exiting through the second annular glass 203. A high-speed airflow layer is formed on the surface. The presence of the airflow layer reduces the probability of dust and impurities adhering to the outer surface of the second annular glass 203, which helps to ensure the cleanliness of the outer surface of the second annular glass 203. It can effectively avoid interference with the visual detection of the vision probe 206 due to stains on the outer surface of the second annular glass 203. Furthermore, during the airflow transportation process, by opening the third annular channel 403 on the mating surface of the relatively rotating inner ring frame 304 and outer ring frame 305, the airflow transfer can be carried out by means of the third annular channel 403, which can avoid the impact of the circumferential movement of the vision detection mechanism on the airflow transportation, thus helping to ensure the stability of the device during operation.

[0047] Please see Figure 2 , Figure 7 and Figure 10 As shown, the vertical cylinder 2 is rotatably connected to the circular ring 102. A second gear 5 is fixed on the vertical cylinder 2. An internal gear ring 501, coaxially arranged with the fireproof ring plate 101, is fixed on the outer shell 104. The second gear 5 meshes with the inner side of the internal gear ring 501. A high-temperature resistant brush 502 adapted to the second annular glass 203 is fixed on the inner ring frame 304. When the device is running, during the process of the circular ring 102 driving the visual inspection mechanism to rotate, because the vertical cylinder 2 is rotatably mounted on the circular ring 102, and the second gear 5 meshing with the inner side of the internal gear ring 501 is fixed on the vertical cylinder 2, the circular ring 501 is affected by the fixed connection between the internal gear ring 501 and the outer shell 104, causing the circular ring 501 to rotate. During the rotation of the visual inspection mechanism, the vertical cylinder 2 drives the protective shell 201 to rotate relative to the high-temperature resistant brush 502 fixed on the inner ring frame 304. During the relative rotation, the high-temperature resistant brush 502 wipes the outer surface of the second annular glass 203. The high-temperature resistant brush 502 is located on the side of the protective shell 201 away from the fireproof ring plate 101, so it will not interfere with the visual acquisition of the visual probe 206. With the help of the wiping of the high-temperature resistant brush 502 and the air curtain formed by the jet airflow in the nozzle 401, the cleanliness of the outer surface of the second annular glass 203 can be effectively guaranteed.

[0048] Please see Figure 7As shown, a first ring box 6 and a second ring box 601 are fixed on the ring 102 and rotatably sleeved on the outside of the vertical cylinder 2. A first through hole 602 is opened on the end wall of the vertical cylinder 2, connecting the water supply channel 302 and the first ring box 6, and a second through hole 603 is opened between the return water channel 303 and the second ring box 601. The first ring box 6 is connected to the inside of the first annular channel 306 from the side of the inner ring frame 304. The second ring box 601 is connected to the inside of the second annular channel 307 from the side of the inner ring frame 304. A third ring box 604 is fixed on the first ring box 6 and rotatably sleeved on the outside of the vertical cylinder 2. An outer sleeve 605 is fixed on the outside of the vertical cylinder 2 and rotatably connected to the third ring box 604. The outer sleeve 605 is connected to the inner wall of the airflow channel 4. The third ring box 604 is connected to the inside of the third annular channel 403 from the side of the inner ring frame 304. The air pump 402 is connected to the inside of the third annular channel 403 from the side of the outer ring frame 305.

[0049] During operation, the vertical cylinder 2 rotates relative to the annular ring 102. To ensure the stability of the coolant and water flow, a first annular box 6, a second annular box 601, and a third annular box 604 are provided in cooperation. During coolant delivery, coolant is delivered from the inner annular frame 304 side to the first annular box 6 through the first annular channel 306, and then enters the water supply channel 302 through the first through hole 602. During coolant return, the coolant returning to the chamber enters the return water channel 303, then enters the second annular box 601 through the second through hole 603, and then enters the second annular channel 307 from the inner annular frame 304 side. Inside, during the airflow transport process, the airflow is transported from one side of the inner ring frame 304 to the third ring box 604 through the third annular channel 403, and then enters the outer sleeve 605. Finally, it is transported to the airflow channel 4 through the outer sleeve 605. Through the relative rotational connection between the first ring box 6, the second ring box 601 and the vertical cylinder 2, and the relative rotational connection between the third ring box 604 and the outer sleeve 605, combined with the relative rotation of the inner ring frame 304 and the outer ring frame 305, and the first annular channel 306, the second annular channel 307 and the third annular channel 403 that are opened around their contact positions, the stability of the coolant and airflow transport in the device can be effectively guaranteed.

[0050] Please see Figure 5 , Figure 10 and Figure 11As shown, multiple liquid storage tanks 301 are provided, and the colors of the coolant stored in the multiple liquid storage tanks 301 are different. Two pipe switching mechanisms are fixed inside the outer shell 104. One pipe switching mechanism is connected between the multiple liquid storage tanks 301 and the inlet of the water pump 3. The other pipe switching mechanism is connected from one side of the outer ring frame 305 between the second annular channel 307 and the multiple liquid storage tanks 301. The pipe switching mechanism includes a circular box 7 fixed inside the outer shell 104, and multiple first connecting pipes 701 are fixedly connected to the cylindrical surface of the circular box 7. A cylinder 702 adapted to its internal size is rotatably installed inside the circular box 7, and a third through hole 703 is opened on the cylindrical surface of the cylinder 702. A third servo motor 704 for driving the cylinder 702 to rotate is fixed on the outside of the circular box 7. A second connecting pipe 705 communicating with the inside of the cylinder 702 is provided on the side of the circular box 7 away from the third servo motor 704.

[0051] During operation, in the pipe switching mechanism between numerous liquid storage tanks 301 and water pumps 3, numerous first connecting pipes 701 are connected to the contents of numerous liquid storage tanks 301, and second connecting pipes 705 are connected to the inlet of water pumps 3. In the pipe switching mechanism between the second annular channel 307 and numerous liquid storage tanks 301, numerous first connecting pipes 701 are connected to numerous liquid storage tanks 301, and second connecting pipes 705 are connected to the second annular channel 307 from one side of the outer ring frame 305. When visually inspecting the flame pattern, the operator, as needed, controls the third servo motor 704 to be energized and started. The third servo motor 704 drives the cylinder 702 to rotate within the circular box 7, adjusting the position of the third through hole 703. When the third through hole 703 aligns with the first connecting pipe 701, the first connecting pipe 701 is connected to the contents of the cylinder 702. In this state, if water pump 3 is in operation... When electrically started, the coolant in the corresponding storage tank 301 enters the cylinder 702 through the connection of the first connecting pipe 701 and the third through hole 703, and then enters the water pump 3 through the second connecting pipe 705. Subsequently, it enters the chamber along the coolant delivery pipeline, and then flows back to the corresponding storage tank 301 through another pipeline switching mechanism connecting the second annular channel 307 and the storage tank 301. Driven by the third servo motor 704 in the two pipeline switching mechanisms, the two cylinders 702 in the two pipeline switching mechanisms are driven to rotate synchronously and adjust the connection state between the third through hole 703 and the first connecting pipe 701. According to the requirements, the color of the coolant flowing through the chamber is continuously adjusted, and the filter of the image captured by the vision probe 206 is realized at the physical level. Visual detection of flame shape under different filters can effectively improve the comprehensiveness of detection, thereby helping to improve the accuracy of detection.

[0052] Please see Figure 5As shown, a third connecting pipe 706 is fixed on the cylindrical surface of the circular box 7, positioned between two adjacent first connecting pipes 701. During operation, the third connecting pipe 706 within the pipe switching mechanism between the liquid storage tank 301 and the water pump 3 is connected to the air outlet of the air pump 402. The third connecting pipe 706 within the pipe switching mechanism between the first connecting pipe 701 and the liquid storage tank 301 is in a closed state. When the pipe switching mechanism between the water pump 3 and the liquid storage tank 301 is activated, during the switching process of coolant delivery in the liquid storage tank 301 corresponding to the two adjacent first connecting pipes 701, it is necessary to... The airflow first passes through the third connecting pipe 706. At this time, the airflow output from the air pump 402 enters the cylinder 702 through the connection between the third connecting pipe 706 and the third through hole 703. Then, it blows the residual coolant in the pipeline back to the corresponding storage tank 301 along the coolant delivery pipeline. Then, the coolant of other colors circulates. By setting the third connecting pipe 706, the residual coolant in the pipeline is recovered first when switching between different colors of coolant, which can avoid the mixing and interference of different colors of coolant, and thus help ensure the stability of the device during operation.

[0053] During the use of the flame pattern visual inspection device, the detector body 205 is rotated by the second servo motor 207, adjusting the orientation of the visual probe 206 so that the visual probe 206 points through the first annular glass 202 and the second annular glass 203 to the ignition point inside the fireproof ring plate 101, visually acquiring the flame pattern of the ignition point. The first servo motor 105 drives the ring 102 to continuously rotate, causing the visual inspection mechanism to move around the ignition point. Simultaneously, the orientation of the visual probe 206 is continuously adjusted by the rotation drive of the second servo motor 207, so that the visual probe 206 always visually acquires the flame pattern of the ignition point during the circling movement. During the visual inspection, the water pump 3 is powered on and started, and in conjunction with the pipe switching mechanism, coolant stored in different liquid storage tanks 301 is delivered to the chamber between the first annular glass 202 and the second annular glass 203 as needed. The visual probe 206 completes the physical filter operation during visual inspection through the coolant of different colors in the chamber, visually inspecting the flame pattern under different filters.

[0054] The above are merely the best implementation methods adopted in this application in light of current practical needs, but the scope of protection of this application is not limited thereto.
