[0020] To enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit disclosure. The described embodiments are some, but not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0021] like Figures 1 to 6 As shown, an embodiment of the present invention provides a furnace temperature field visualization detection device that eliminates the need for boiler wall openings, including an explosion-proof box 1, a detection component 2, and an adjustment component 3; The detection component 2 includes a temperature-measuring flame detection probe 209 and a display screen 211. The temperature-measuring flame detection probe 209 and the display screen 211 are respectively located on opposite sides of the explosion-proof box 1. The display screen 211 is used to display the detection results of the temperature-measuring flame detection probe. The adjustment component 3 is driven and connected to the temperature-measuring flame detection probe 209. The adjustment component 3 is used to adjust the extension and retraction length of the temperature-measuring flame detection probe 209.

[0022] The furnace temperature field visualization detection device without boiler wall openings according to this invention includes an explosion-proof enclosure 1, a detection component 2, and an adjustment component 3. The temperature-measuring flame detection probe 209 of the detection component 2 and the display screen 211 are respectively connected to the side walls of opposite sides of the explosion-proof enclosure 1. The adjustment component 3 and the temperature-measuring flame detection probe 209 are located on the same side wall of the explosion-proof enclosure 1. The adjustment component 3 is driven and connected to the temperature-measuring flame detection probe 209. By driving the temperature-measuring flame detection probe 209 to extend and retract, the temperature-measuring flame detection probe 209 can be inserted into the boiler furnace, and its depth within the furnace can be adjusted to measure the temperature at different locations within the furnace. The display screen 211 displays the temperature data detected by the temperature-measuring flame detection probe 209 at different locations within the furnace, allowing operators to obtain real-time information on changes in the temperature field within the furnace and adjust boiler parameters accordingly. The detection device of the present invention extends the temperature-measuring flame detection probe 209 into the existing process hole of the boiler furnace, without the need to open new holes in the boiler furnace wall, thus avoiding problems such as wall structure damage and furnace air leakage caused by opening holes in the boiler.

[0023] like Figure 2As shown, in some embodiments of the present invention, the detection component 2 further includes a temperature field processing unit 201, an image visualization unit 202, a fire detection intelligent analysis unit 203, and a signal conditioning unit 204 disposed within the explosion-proof enclosure 1; the temperature-measuring flame detection probe 209 is electrically connected to the signal conditioning unit 204, the signal conditioning unit 204 is electrically connected to the fire detection intelligent analysis unit 203, the fire detection intelligent analysis unit 203 is electrically connected to the temperature field processing unit 201, the temperature field processing unit 201 is electrically connected to the image visualization unit 202, and the image visualization unit 202 is electrically connected to the display screen 211. Specifically, after the temperature-measuring flame detection probe 209 collects the raw signal from the furnace, the signal conditioning unit 204 first performs preprocessing such as amplification, filtering, and analog-to-digital conversion to form a processable digital signal. Then, the intelligent flame detection analysis unit 203 uses a preset algorithm to identify flame characteristics and calculate the temperature value at each point. The preset algorithm may be spectral analysis or a neural network model. Next, the temperature field processing unit 201 reconstructs the temperature field distribution of the entire cross-section based on multi-point or scan data through algorithms such as interpolation fitting. The image visualization unit 202 converts the discrete temperature data into a pseudo-color thermogram or isotherm map. Finally, the intuitive temperature field visualization image is displayed in real time on the display screen 211, which facilitates the staff to observe the furnace operating conditions in real time and perform corresponding control operations. In this embodiment, each unit adopts an independent modular layout, which not only reserves sufficient installation space and component arrangement positions inside the explosion-proof box 1, but also significantly improves the operating efficiency and working stability of each unit.

[0024] In some embodiments of the present invention, the detection assembly 2 further includes a wedge plate 205, a flange 206, and a blocking ring 207. The wedge plate 205 is fixedly connected to one side of the explosion-proof box 1, and the wedge plate 205 is connected to the flange 206. The inner ring of the flange 206 is fixedly connected to the outer ring of the blocking ring 207. The temperature-measuring flame detection probe 209 is slidably inserted through the blocking ring 207. Specifically, the wedge plate 205 is fixedly connected to the side wall of one side of the explosion-proof box 1, and the flange 206 is fixed to one side of the explosion-proof box 1 by the wedge plate 205. The flange 206 and the wedge plate 205 provide support for the temperature-measuring flame detection probe 209, allowing the temperature-measuring flame detection probe 209 to be slidably connected to one side of the explosion-proof box 1, so that the temperature-measuring flame detection probe 209 can extend and retract within the furnace.

[0025] like Figure 2 , Figure 3As shown, in some embodiments of the present invention, the detection component 2 further includes a protective sleeve 208, which is sleeved on the temperature-measuring flame detection probe 209. The protective sleeve 208 passes through the blocking ring 207, and the outer wall of the protective sleeve 208 is slidably connected to the inner ring wall of the blocking ring 207. Specifically, the protective sleeve 208 is sleeved on the temperature-measuring flame detection probe 209, and the protective sleeve 208 and the temperature-measuring flame detection probe 209 will not move relative to each other. The protective sleeve 208 is slidably connected to the blocking ring 207, that is, the temperature-measuring flame detection probe 209 is slidably connected to the blocking ring 207 through the protective sleeve 208, so that the temperature-measuring flame detection probe 209 can move relative to the blocking ring 207. The device utilizes the existing openings in the furnace to install temperature-measuring flame detection probes 209, eliminating the need for additional openings in the boiler wall. The adjustment component 3 precisely controls the probe insertion depth, and the probes collect furnace temperature field signals in real time. These signals are then analyzed and processed step by step by each unit within the enclosure. The blocking ring 207 prevents smoke and flame from escaping, and the protective sleeve 208 protects the probe from high temperatures. Finally, the visualized temperature field image is transmitted in real time to the display screen 211, facilitating real-time monitoring of the furnace conditions and timely adjustments by the staff.

[0026] Furthermore, the blocking ring 207 is made of high-temperature and corrosion-resistant material. The blocking ring 207 can prevent the smoke and heat inside the furnace from escaping outward, ensuring smooth sliding between the temperature-measuring flame detection probe 209 and the protective sleeve 208, and effectively reducing heat loss from the furnace. The protective sleeve 208 is also made of high-temperature and corrosion-resistant material, which can isolate the smoke and heat inside the furnace and prevent the high temperature and smoke inside the furnace from damaging the detection end of the temperature-measuring flame detection probe 209.

[0027] like Figure 4 As shown, in some embodiments of the present invention, the detection component 2 further includes a connecting block 210, which is fixedly connected to the side wall of the explosion-proof box 1 on the side opposite to the temperature-measuring flame detection probe 209. The display screen 211 is fixedly connected to the connecting block 210. Specifically, the connecting block 210 and the wedge plate 205 are respectively disposed on opposite sides of the explosion-proof box 1. The connecting block 210 and the wedge plate 205 provide installation support for the display screen 211 and the flange 206 respectively, ensuring that the temperature-measuring flame detection probe 209 and the display screen 211 do not interfere with each other. In this embodiment, the fixing block is disposed on the left side of the explosion-proof box 1, and the wedge plate 205 is disposed on the right side of the explosion-proof box 1. There are two fixing blocks, which are arranged at intervals along the height direction of the explosion-proof box 1. The two fixing blocks are respectively connected to the side wall of the display screen 211. The reliability of the connection between the display screen 211 and the explosion-proof box 1 can be improved by using two spaced-apart fixing blocks.

[0028] like Figure 5 , Figure 6As shown, in some embodiments of the present invention, the adjusting assembly 3 includes at least one fixed plate 308, at least one multi-stage electric push rod 304, a first connecting plate 303, and a fixed ring 301. The fixed plate 308 is connected to the side wall of one side of the explosion-proof box 1. The fixed plate 308 is fixedly connected to the fixed end of the multi-stage electric push rod 304 and arranged in a one-to-one correspondence. The movable end of the multi-stage electric push rod 304 is fixedly connected to the first connecting plate 303. The outer ring of the fixed ring 301 is fixedly connected to the first connecting plate 303, and the inner ring of the fixed ring 301 is fixedly connected to the temperature-measuring flame detection probe 209. Specifically, the fixing plate 308 and the wedge plate 205 are located on the same side of the explosion-proof box 1. The fixing plate 308 provides support for the multi-stage electric push rod 304. When it is necessary to adjust the depth of the temperature-measuring flame detection probe 209 in the furnace, the movable end of the multi-stage electric push rod 304 pushes the first connecting plate 303 and the fixed ring 301 connected to the first connecting plate 303 to extend and retract together, so that the first connecting plate 303 drives the temperature-measuring flame detection probe 209 fixedly connected to it to move to different positions in the furnace and measure the temperature field at different positions in the furnace. The design of the multi-stage electric push rod 304 can not only push the first connecting plate 303 to exert a stable and strong thrust, but also maximize the extension and retraction in a limited space.

[0029] Furthermore, a protective tube 305 is fitted on the outer circumference of each multi-stage electric push rod 304. The protective tube 305 can extend and retract with the multi-stage electric push rod 304, so that the protective tube 305 protects the multi-stage electric push rod 304 in real time.

[0030] In some embodiments of the present invention, the first connecting plate 303 includes two opposing connecting plate bodies, each having a semi-circular through groove. The two connecting plate bodies are connected and form a through hole extending through the thickness of the hole. The outer ring of the fixing ring 301 is fixedly installed in the through hole. Specifically, the two connecting plate bodies are connected to form the first connecting plate 303, and the two connecting plate bodies form a through hole for installing the fixing ring 301, so as to facilitate the installation and removal of the fixing ring 301.

[0031] In some embodiments of the present invention, the adjusting assembly 3 includes two fixed plates 308 and two multi-stage electric push rods 304. The two fixed plates 308 are fixedly spaced on one side of the explosion-proof box 1. Each fixed plate 308 is connected to the fixed end of the corresponding multi-stage electric push rod 304. The movable ends of the two multi-stage electric push rods 304 are respectively connected to the first connecting plate 303, and a portion of the temperature-measuring flame detection probe 209 is located between the two multi-stage electric push rods 304. Specifically, the two fixed plates 308 are spaced apart along the height direction of the explosion-proof box 1. Each fixed plate 308 is fixedly connected to the fixed end of a multi-stage electric push rod 304, and the movable end of each multi-stage electric push rod 304 is fixedly connected to the two connecting plates of the first connecting plate 303, so that the first connecting plate 303 is subjected to more uniform force. The two multi-stage electric push rods 304 are respectively located above and below the temperature-measuring flame detection probe 209, and each multi-stage electric push rod 304 is spaced apart from the temperature-measuring flame detection probe 209. The two sets of multi-stage electric push rods 304 maintain the same moving speed and operating frequency, enabling them to synchronously drive the first connecting plate 303 to move smoothly.

[0032] In some embodiments of the present invention, the adjusting component 3 further includes a protective ring 302; the outer ring of the protective ring 302 is fixedly connected to the inner ring of the fixed ring 301, and the inner ring of the protective ring 302 is fixedly connected to the temperature-measuring flame detection probe 209. Specifically, the protective ring 302 can protect the connection between the temperature-measuring flame detection probe 209 and the connecting wire, and the protective ring 302 has a wire-passing hole inside to facilitate the routing of the probe connecting wire.

[0033] In some embodiments of the present invention, the adjusting assembly 3 further includes a second connecting plate 306 and a slide rod 307; the slide rod 307 is connected to the outer wall of the explosion-proof box 1 and extends along the extension and retraction direction of the multi-stage electric push rod 304; the second connecting plate 306 is provided with a sliding groove adapted to the slide rod 307, and the second connecting plate 306 is fixedly connected to the first connecting plate 303. Specifically, the extension direction of the slide rod 307 is the same as the extension and retraction direction of the multi-stage electric push rod 304. When the first connecting plate 303 undergoes displacement, the second connecting plate 306 fixed on the first connecting plate 303 and the slide rod 307 cooperate to guide each other, ensuring that the first connecting plate 303 does not shift position during movement.

[0034] Furthermore, the guide structure consisting of the first connecting plate 303 and the slide bar 307 is in two sets. The two sets of guide structures are connected to the side wall of the explosion-proof box 1 at intervals along the height direction of the explosion-proof box 1. The second connecting plates 306 of the two sets of guide structures are respectively connected to the first connecting plate 303 to provide dual guidance for the movement of the first connecting plate 303 and ensure that the movement of the first connecting plate 303 is more stable.

[0035] Working principle of this invention: When the depth of the temperature-measuring flame detection probe 209 and the protective sleeve 208 within the furnace needs to be adjusted, two multi-stage electric push rods 304 are driven to move the first connecting plate 303 and the fixed ring 301 respectively. Guided by the second connecting plate 306 and the slide rod 307, the first connecting plate 303 drives the temperature-measuring flame detection probe 209 through the existing process holes in the furnace and into the furnace, where it extends and retracts to meet the requirements of detecting the temperature field at different locations within the furnace. The temperature-measuring flame detection probe 209 undergoes preprocessing such as amplification, filtering, and analog-to-digital conversion through the signal conditioning unit 204 to form a processable digital signal. The flame detection intelligent analysis unit 203 analyzes the data signal and calculates the temperature value at each point. The temperature field processing unit 201 reconstructs the temperature field distribution from the temperature values ​​at each point. The image visualization unit converts the temperature field distribution data into a visual image and transmits it to the display screen 211 for display, allowing operators to observe the furnace conditions in real time and perform corresponding control operations.

[0036] The furnace temperature field visualization detection device without boiler wall openings according to the embodiments of the present invention also has the following beneficial effects: 1. The explosion-proof enclosure integrates temperature field processing, image visualization, intelligent flame detection analysis and signal conditioning units, and forms an electrical linkage with the temperature-measuring flame detection probe. It can quickly complete furnace temperature acquisition, data analysis and image visualization output. The wedge plate, flange and blocking ring, together with the protective sleeve, form a sliding protective structure to ensure smooth probe extension and adjustment while preventing high-temperature flue gas from leaking out. The display screen is firmly installed through the connecting block, which makes it convenient for operators to view and adjust parameters in real time. It is suitable for the high temperature and harsh working conditions of boilers and significantly improves the accuracy and reliability of furnace temperature field detection. 2. A reliable connection with the temperature-measuring flame detection probe is achieved through a fixed ring. The protective tube can provide effective heat insulation protection for the internal multi-stage electric push rods. The multi-stage electric push rods, together with the slide rod, the first connecting plate and the second connecting plate, form a sliding guide structure, which can smoothly drive the probe to make fine adjustments to its position. At the same time, the overall structural design allows for installation without opening holes in the boiler wall, avoiding problems such as damage to the wall structure and heat loss due to furnace air leakage caused by opening holes in the boiler.

[0037] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of the present invention, and the present invention is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also considered to be within the scope of protection of the present invention.
