Description

Technical Field

[0001] This invention relates to the field of boiler scale detection technology, and in particular to a boiler scale detection method and apparatus based on multimodal images. Background Technology

[0002] Boilers are core equipment in thermal power generation, chemical industry, and heating, and the formation of scale on their inner walls can severely affect operational efficiency. Simultaneously, scale buildup can cause uneven heating, leading to localized high-temperature creep on the boiler wall and even safety accidents such as tube rupture. Therefore, regular and accurate detection of scale on the boiler's inner walls is crucial for ensuring the safe and efficient operation of boilers. Current scale detection methods largely rely on manual inspections or single-image detection equipment. Manual inspections are inefficient, have many blind spots, and cannot quantify scale thickness and composition. While single-image detection devices are equipped with image sensors, they can only image using visible light, making it difficult to identify thin layers of scale or scale similar in color to the boiler wall, resulting in limited detection accuracy. Furthermore, residual dust and impurities inside the boiler can interfere with the image sensor's imaging quality, leading to detection errors. Traditional devices also lack the ability to simultaneously detect boiler sealing issues, failing to promptly identify abnormal environmental conditions caused by leaks, thus failing to meet the demand for "comprehensive, accurate, and efficient" boiler scale detection.

[0003] To address the above problems, this invention proposes a method and apparatus for detecting boiler scale based on multimodal images. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing scale detection methods that rely heavily on manual inspections or single-image detection devices. While single-image detection devices are equipped with image sensors, their detection accuracy is limited. Furthermore, residual dust and impurities inside the boiler can interfere with the imaging quality of the image sensor, leading to detection errors. In addition, traditional devices lack the ability to simultaneously detect the boiler's sealing performance, making it impossible to detect abnormal detection environments caused by leaks in a timely manner. Therefore, this invention proposes a boiler scale detection method and device based on multimodal images.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A boiler scale detection device based on multimodal images includes a detection mechanism disposed in the boiler body; The detection mechanism includes a sealing adjustment assembly, the lower end of which is provided with an installation cavity. A vacuum device and a gas supply assembly are provided in the installation cavity. Two sealing airbags are respectively connected to both ends of the gas supply assembly, and the two sealing airbags are installed on the periphery of the installation cavity. A drive assembly is provided on the mounting cavity, and multiple active adjustment components and passive adjustment components are arranged around the drive assembly. An adjustment detection component is provided on one side of the active adjustment component.

[0006] Preferably, the sealing adjustment assembly includes a mounting base, which is installed above the furnace body, and a telescopic structure is mounted on the mounting base, with the lower end of the telescopic structure fixedly connected to the mounting cavity.

[0007] Preferably, the drive assembly includes a gear ring and two rotating rings, both of which are rotatably mounted on the mounting cavity via bearings, and multiple mounting brackets are fixedly connected to the two rotating rings.

[0008] Preferably, the gear ring is rotatably mounted on a bearing connected to a swivel ring, the gear ring meshes with a drive structure, and the drive structure is mounted on a mounting cavity.

[0009] Preferably, the passive adjustment component includes a telescopic frame, with both ends of the telescopic frame hinged to two guide rails respectively. One guide rail is fixedly connected to a mounting frame, and a slider is slidably connected to the guide rail. The slider is hinged to the other two ends of the two telescopic frames, and a spring is fixedly connected between the slider and the side wall of the guide rail.

[0010] Preferably, the active adjustment component includes two shaft disks, on which a first gear is fixedly connected. The upper and lower first gears respectively mesh with two gear rings, which are rotatably mounted on the mounting frame via bearings. The shaft discs are rotatably mounted on the mounting frame via bearings. One end of each of the two shaft discs is fixedly connected to the output shaft of one of the two motors. The motors are mounted on the mounting frame. The same rope is wound around the two shaft discs, and the rope passes through both ends of the two guide rails and around the guide wheel to form a U-shaped structure.

[0011] Preferably, the adjustment and detection component includes an outer frame, which is fixedly connected to a guide rail. The guide wheel is rotatably connected to the outer frame, and a slide rod is fixedly connected to the outer frame. A sliding sleeve is slidably connected to the slide rod, and one end of the sliding sleeve is mounted on a rope.

[0012] Preferably, a toothed plate is fixedly connected to the sliding sleeve, the toothed plate meshes with the shaft teeth, the shaft teeth are rotatably mounted on the outer frame via bearings, and a detection probe is fixedly connected to the shaft teeth.

[0013] Preferably, the gas delivery assembly includes a fan device, one end of which extends upward through the mounting cavity, and the other end of which is connected to a delivery pipe. Both ends of the delivery pipe are equipped with solenoid valves, and both ends of the delivery pipe extend through the mounting cavity and are respectively connected to two sealing airbags. Multiple ropes are provided between the upper and lower walls of the sealing airbags. The upper end of the vacuum device extends upward through the mounting cavity, and the lower end of the vacuum device extends out of the mounting cavity and is located between two sealed air bladders. A pressure sensor is installed on the vacuum device.

[0014] A detection method for boiler scale detection devices based on multimodal images includes the following steps: S1. During testing, the testing mechanism is installed on the furnace body. The sealing airbag is then lowered through the telescopic structure to the bottom of the furnace body's inner cavity, leaving a space. At this time, the upper solenoid valve is opened, and the upper sealing airbag is inflated by the blower, which expands the sealing airbag to achieve the sealing effect. Then, the vacuum equipment evacuates the space below the upper sealing airbag, and the pressure sensor equipped with the vacuum equipment effectively detects the airtightness. S2. After sealing, two motors switch between forward and reverse rotation, and multiple shaft discs rotate under the transmission of the first gear and gear ring. The two shaft discs switch between winding and unwinding the rope, causing the sliding sleeve to drive the toothed plate to move. The toothed plate and shaft teeth drive each other, allowing the angle of the detection probe to be adjusted. After the detection probe is adjusted up and down, the top and bottom cavities of the furnace body can be detected. When the detection probe is in a horizontal state, it can be used to detect the side walls of the furnace body. At the same time, when the two motors rotate forward synchronously, they drive the shaft discs to wind up the rope, causing the telescopic frame to retract. The slider drives the spring to deform, thus smoothly adjusting the position of the detection probe for detection. At the same time, the motors rotate in reverse synchronously, causing the spring to drive the telescopic frame to unfold, allowing the detection probe to expand outward for further detection. S3. During the detection process, the drive structure drives the gear ring to rotate, the gear ring drives the rotating ring to rotate, and the rotating ring drives the passive adjustment component and the active adjustment component to move, so that the detection probe rotates to perform the detection operation. S4. When it is necessary to adjust the position upwards for the next round of testing, the air in the upper sealing airbag is discharged by the blower, and then the telescopic structure is adjusted upwards by a certain position. Then, the two solenoid valves are opened simultaneously, and the vacuum equipment is used to evacuate the sealed space between the two sealing airbags. The testing operation is carried out again. The furnace body is tested section by section by adjusting the position upwards in this way.

[0015] Compared with the prior art, the present invention provides a method and apparatus for boiler scale detection based on multimodal images, which has the following beneficial effects: 1. This boiler scale detection method and device based on multimodal images can adjust the angle of the detection probe by linking the active adjustment component with the detection component, thereby adapting to the diverse angle detection needs of the boiler body and ensuring the comprehensiveness and accuracy of the detection operation. In addition, the active adjustment component can also link with the passive adjustment component to realize the free adjustment of the position of the detection probe, thereby achieving all-round, blind-angle detection coverage of the inner wall of the boiler. At the same time, the detection probe is a detection module with different functions and is equipped with a multi-band image sensor, thereby realizing high-precision detection of the inner wall of the boiler.

[0016] 2. The boiler scale detection method and device based on multimodal images can adjust the vertical position of the detection probe through a telescopic structure, thereby achieving the purpose of segmented detection of the boiler body. The gas supply component can inflate the sealing airbag to ensure the sealing of each segment space. In addition, it can cooperate with the vacuum equipment to achieve vacuuming operation, and then use the pressure sensor to achieve zoned detection of sealing, thereby quickly identifying the leak point.

[0017] 3. This boiler scale detection method and device based on multimodal images expands the sealing airbag through the gas supply component, thereby maintaining the sealing of each section and enabling the vacuum equipment to perform vacuuming operations. Vacuuming removes impurities, and the clean detection area allows each detection probe to capture more realistic scale characteristics, avoiding mismatch of multimodal data caused by impurities and improving the reliability of detection results. Furthermore, the drive component and active adjustment component, in conjunction with the passive adjustment component and the adjustment detection component, can achieve multi-directional adjustment of the detection probe to achieve the purpose of multimodal detection. This enables precise analysis of the scale distribution, thickness, and composition on the inner wall of the boiler, while the sealing detection monitors the sealing status in real time. The two are carried out simultaneously, which not only improves the detection efficiency but also ensures the comprehensiveness and accuracy of the detection results. Attached Figure Description

[0022] Example 1: Refer to Figures 1-2 , Figures 4-7 and Figures 9-10 A sampling device for fly ash from a boiler in a thermal power plant includes a separation mechanism 100 and a sampling mechanism 200 mounted on the separation mechanism 100. The sampling mechanism 200 includes a mounting frame 201, on which a fixed frame 202 is fixedly connected. A drying device 204 is installed above the fixed frame 202. The drying device 204 can dry the fly ash sample to facilitate subsequent testing. A sample transfer assembly 203 is provided on the fixed frame 202. The sample transfer assembly 203 includes a turntable 2034 and a first drive structure 2031. The first drive structure 2031 is mounted on the fixed frame 202 and meshes with a first gear 2032. The first gear 2032 and the turntable 2034 are rotatably mounted via bearings. On the support shaft 2033, the first gear 2032 is connected to the turntable 2034 through the bearing. The rotation of the first gear 2032 can drive the turntable 2034 to rotate through the bearing, thereby causing the sampling chambers 2035 to alternately switch positions, so as to continuously sample. The support shaft 2033 is fixedly connected to the fixed frame 202. The sampling chambers 2035 are fixedly connected to the outer side of the turntable 2034. The two ends of the sampling chambers 2035 overlap with the fixed frame 202. The sampling chambers 2035 are alternately aligned with the discharge port of the cyclone separator 103, the drying equipment 204, the drive component 207 and the outer shell 2055 through rotation. The sample transfer assembly 203 is equipped with multiple flow-disrupting components 206. Each flow-disrupting component 206 includes a sealing cavity 2061 and second bevel teeth 2067. After entering the sampling cavity 2035, the sealing cavity 2061 overlaps with the inner cavity of the sampling cavity 2035, maintaining a seal between the sealing cavity 2061 and the inner cavity of the sampling cavity 2035, thereby preventing the fly ash sample from falling downwards. A scraper frame 2062 overlaps above the sealing cavity 2061. After entering the sampling cavity 2035, the scraper frame 2062 adheres to the inner wall of the sampling cavity 2035. The scraper frame 2062 not only adheres to the inner wall of the sampling cavity 2035 but also overlaps with the sealing cavity. Contact 2061 allows the scraper frame 2062 to move smoothly and clean the surfaces of the sampling chamber 2035 and the sealing chamber 2061, preventing sample residue. The scraper frame 2062 is fixedly connected to the top of the column tooth 2063. The clamping structure 2076 is used to clamp the column tooth 2063. The column tooth 2063 and the second bevel tooth 2067 are rotatably connected to the sealing chamber 2061 through bearings. A first bevel tooth 2064 is fixedly connected to the column tooth 2063. The first bevel tooth 2064 and the second bevel tooth 2067 mesh with the bevel tooth shaft 2065. Through the transmission of the first bevel tooth 2064 and the bevel tooth shaft 2065, the bevel tooth shaft 2065 also engages with... The second bevel gear 2067 drives the sealing cavity 2061 and the scraper frame 2062 to move in opposite directions, facilitating sample removal from the surface of the sealing cavity 2061. The bevel gear shaft 2065 is rotatably mounted on the fixing member 2066 via bearings. The fixing member 2066 is fixedly connected in the sealing cavity 2061. A grinding assembly 205 is provided below the fixing frame 202. The grinding assembly 205 includes a second drive structure 2051 and a grinding shell 2053. The second drive structure 2051 is mounted on the fixing frame 202 and meshes with the gear ring 2052. Through the second drive structure 2051 and the first... The drive structure 2031 consists of a motor and gears, which drive the gear ring 2052 to rotate. The gear ring 2052 can drive the grinding shell 2053 to rotate, so that the grinding shell 2053 and the grinding head 2054 can smoothly perform fine processing on the sample, which is convenient for subsequent testing operations. The gear ring 2052 is installed on the grinding shell 2053. The grinding shell 2053 is rotatably installed on the outer shell 2055 through bearings. The outer shell 2055 is fixedly connected to the fixing frame 202. The grinding head 2054 is set inside the grinding shell 2053. The grinding head 2054 is fixedly connected to the outer shell 2055 through a fixing rod. A detection component 208 is disposed below the grinding assembly 205. Both the interior of the grinding assembly 205 and the lower part of the fixing frame 202 are equipped with drive components 207. The drive components 207 drive the turbulence component 206. The drive component 207 includes a fixing plate 2074, with two electric push rods 2071 fixedly connected to the lower part of the fixing plate 2074. Two electric push rods 2071 are installed in the grinding head 2054, and the other two electric push rods 2071 are mounted below the fixing frame 202 via a support frame. Ball bearings 2077 are mounted on the electric push rods 2071, and the two ball bearings 2077 are slidably connected in the spiral groove 2073. During the up-and-down movement of the connecting shaft 2072, the ball bearings 2077 pass through the spiral groove 2073. The arc surface of 73 can cooperate with the ball bearing 2077 to realize the rotation of the connecting shaft 2072. The spiral groove 2073 is opened on the connecting shaft 2072. One of the connecting shafts 2072 slides in the grinding head 2054. The connecting shaft 2072 is rotatably mounted on the fixed plate 2074 through the bearing. The connecting shaft 2072 can rotate stably through the bearing, thereby making the positioning cavity 2075 rotate stably. The top end of the connecting shaft 2072 is fixedly connected to the positioning cavity 2075. Two clamping structures 2076 are provided in the positioning cavity 2075. The clamping structure 2076 is composed of an electric cylinder and a clamping component, so that the electric cylinder can control the clamping component to clamp the column tooth 2063, realizing the stable connection between the drive component 207 and the turbulence component 206.

[0023] In this embodiment: the first drive structure 2031 drives the first gear 2032 to rotate, causing the turntable 2034 to drive the sampling chamber 2035 to rotate. Each sampling chamber 2035 cycles through each other, sequentially transferring the collected fly ash to the drying device 204 for drying. During drying, the electric push rod 2071 pushes the fixing plate 2074 upward, the positioning cavity 2075 engages with the column tooth 2063, and is clamped and fixed by the clamping structure 2076. Then, the electric push rod 2071 moves up and down, causing the spiral groove 2035 to rotate. 73 works in conjunction with the ball bearing rod 2077 to rotate the connecting shaft 2072. The connecting shaft 2072 drives the scraper frame 2062 to agitate the fly ash flow, facilitating rapid drying of the fly ash and preventing clumping. After drying, the fly ash is transferred to the grinding component 205 and fed through the drive component 207 in conjunction with the turbulence component 206, preventing sample residue. Then, the grinding component 205 performs fine grinding to ensure uniform fly ash properties, which is convenient for sealed collection and provides high-quality samples for subsequent laboratory fine testing and biomass energy product testing services.

[0024] Example 2: Refer to Figures 1-3 and Figure 8A sampling device for fly ash from a boiler in a thermal power plant includes a separation mechanism 100. The separation mechanism 100 includes a pipe 101, a mounting frame 201 mounted on the pipe 101, a sampling head 104 installed in the pipe 101, and the sampling head 104 connected to a cyclone separator 103. The fly ash can be separated by the cyclone separator 103, and the separated gas is discharged back into the pipe 101 by a fan 102. The outlet of the cyclone separator 103 is mounted on the mounting frame 202, and the fan 102 is connected above the cyclone separator 103. One end of the fan 102 extends into the pipe 101. The detection assembly 208 includes a collection chamber 2081, which is connected to the bottom of the grinding shell 2053 via a bearing. A sealing cover 2086 is provided below the collection chamber 2081. Samples can be collected through the collection chamber 2081, and the sample can be smoothly discharged by opening the sealing cover 2086, facilitating subsequent collection or detection of the sample. Sampling sections 2087 are provided on both sides of the collection chamber 2081. A detection device 2082 is installed above one sampling section 2087, and an adjusting cylinder 2083 is installed in the other sampling section 2087. One end of the adjusting cylinder 2083 is fixedly connected to a sampling plate 2084. The position of the sampling plate 2084 is adjusted by adjusting the adjusting cylinder 2083, thereby facilitating online sampling operations. A sample outlet 2085 is provided on one side of the sampling plate 2084, which ensures that the sample can smoothly enter the bottom of the collection chamber 2081.

[0025] In this embodiment: fly ash is separated by the separation mechanism 100. After separation, it can enter the detection component 208 for feeding. In the middle of the fly ash feeding section, a sampling plate 2084 is used to take a sample. After sampling, the sampling plate 2084 is pushed by the regulating cylinder 2083 to deliver the sample to the detection area. During the sample pushing process, the sample can be automatically flattened by the sampling section 2087, which facilitates the on-site online chemical composition analysis of the detection equipment 2082, realizes rapid online pre-detection, shortens the detection cycle, and allows for on-site pre-judgment, avoiding the delay in problem discovery. At the same time, it provides preliminary data guidance for subsequent biomass energy product testing services and avoids the invalid flow of unqualified samples.

[0026] Example 3: Reference Figures 1-2 and Figures 4-6A sampling device for fly ash from a boiler in a thermal power plant includes a separation mechanism 100, a sampling mechanism 200 on the separation mechanism 100, a mounting frame 201, a fixed frame 202 fixedly connected to the mounting frame 201, a drying device 204 mounted above the fixed frame 202, a sample transfer assembly 203 on the fixed frame 202, a plurality of turbulence-inducing components 206 in the sample transfer assembly 203, a grinding assembly 205 below the fixed frame 202, a detection assembly 208 below the grinding assembly 205, and a driving assembly 207 inside the grinding assembly 205 and below the fixed frame 202, the driving assembly 207 being used to drive the turbulence-inducing components 206 to work.

[0027] In this embodiment: fly ash is separated by the separation mechanism 100, and the samples are sequentially transferred to the drying zone by the sample transfer component 203. During drying, the drive component 207 works in conjunction with the turbulence component 206 to perform turbulence action, ensuring uniform drying and preventing agglomeration. The samples are then transferred to the grinding zone and guided downwards by the turbulence component 206 to prevent residue, ensuring the integrity and purity of the samples before grinding. Then, the grinding component 205 grinds the samples. The high-quality samples after drying and grinding can be used in conjunction with the detection component 208 to verify the accuracy of the on-site pre-detection results, providing accurate data support for biomass energy product testing services and avoiding detection deviations.

[0028] Working principle: During fly ash pre-detection, the blower 102 operates to take samples through the sampling head 104, and the fly ash is separated by the cyclone separator 103. Excess gas can be discharged back into the pipeline 101 through the blower 102. The fly ash enters the sampling chamber 2035 through the discharge port of the cyclone separator 103. Then, the first drive structure 2031 and the first gear 2032 are controlled to drive the first gear 2032 to rotate. The first gear 2032 drives the turntable 2034 to rotate, and the turntable 2034 drives the sampling chamber 2035 to rotate. The sampling chamber 2035 is located in the drying zone, so that the drying equipment 204 dries the fly ash. During the drying process, the electric push rod 2071 pushes the fixed plate 2074 upward, causing the positioning cavity 2075 to align with the column teeth 2063. At this time, the column teeth 2063 are clamped and fixed by the clamping structure 2076. The electric push rod 2071 moves up and down, causing the connecting shaft 2072 to move up and down. At this time, the spiral groove 2073 and the ball rod 2077 cooperate to drive the connecting shaft 2072 to rotate. The connecting shaft 2072 drives the positioning cavity 2075 to rotate, causing the column teeth 2063 to drive the scraper frame 2062 to rotate. The scraper frame 2062 disturbs the fly ash flow to achieve uniform drying. After drying, the fixing of the column teeth 2063 is removed, and the sample is transferred to the grinding area. At this time, another drive component 207 is connected to the turbulence component 206 again and drives the turbulence component 206 to move downward, so that the sealing cavity 2061 enters the outer shell 2055 downward. Then the turbulence component 206 is driven to rotate. Since the scraper frame 2062 rotates independently, and the first bevel tooth 2064 is also driven by the bevel tooth shaft 2065, and the bevel tooth shaft 2065 is driven by the second bevel tooth 2067, the sealing cavity 2061 and the scraper frame 2062 move in opposite directions. The scraper frame 2062 can scrape off the residue on the inner wall of the sampling cavity 2035 and remove the residue on the sealing cavity 2061. After cleaning, the turbulence component 206 is reset upward to the sampling cavity 2035 and disconnected from the drive component 207, so that the sampling cavity 2035 can be used in cycles. The sample enters the grinding shell 2053, and the second driving structure 2051 drives the gear ring 2052 to rotate. The gear ring 2052 drives the grinding shell 2053 to rotate. The grinding shell 2053, together with the grinding roller, performs grinding on the sample. The ground sample enters the bottom of the collection chamber 2081 for collection. If subsequent testing is required, the sealing cover 2086 can be opened directly to take the sample. During on-site pre-testing, when the sample is discharged to the middle section, the adjusting cylinder 2083 controls the movement of the sampling plate 2084. The sampling plate 2084 enters the discharge position to pick up the sample, and then pushes the sampling plate 2084 into another sampling section 2087. The sample is smoothed by the edge of the sampling section 2087 so that the sample reaches the position of the testing equipment 2082 for testing.

10. The detection method of a boiler scale detection device based on multimodal images according to claim 9, characterized in that, Includes the following steps: S1. During the test, the testing mechanism (200) is installed on the furnace body (100), and the sealing airbag (204) is lowered to the bottom of the inner cavity of the furnace body (100) through the telescopic structure (2011), leaving a space. At this time, the upper solenoid valve (2063) is opened, and the upper sealing airbag (204) is inflated by the fan equipment (2061), so that the sealing airbag (204) can expand to achieve the sealing effect. Then the vacuum equipment (205) evacuates the space below the upper sealing airbag (204), and the pressure sensor equipped in the vacuum equipment (205) effectively detects the air tightness. S2. After sealing, the two motors (211) switch between forward and reverse motion, and under the transmission of the first gear (2093) and the gear ring (210), multiple shaft discs (2091) rotate. The two shaft discs (2091) switch between releasing and winding the rope (2092), causing the sliding sleeve (2033) to drive the toothed plate (2034) to move. The toothed plate (2034) and the shaft teeth (2035) are driven, allowing the angle of the detection probe (2036) to be adjusted. After the detection probe (2036) is adjusted up and down, the top cavity and bottom cavity of the furnace body (100) can be detected. When (2036) is in a horizontal state, it can perform the inspection of the side wall of the furnace body (100). At the same time, when the two motors (211) rotate forward synchronously, they drive the shaft disc (2091) to wind up the rope (2092), causing the telescopic frame (2071) to retract. The slider (2072) drives the spring (2073) to deform, thereby smoothly adjusting the position of the detection probe (2036) for inspection. At the same time, the motor (211) rotates in reverse synchronously, causing the spring (2073) to drive the telescopic frame (2071) to unfold, allowing the detection probe (2036) to expand outward for further inspection. S3. During the detection process, the gear ring (2082) is driven to rotate by the drive structure (2081), the gear ring (2082) drives the rotating ring (2083) to rotate, and the rotating ring (2083) drives the passive adjustment component (207) and the active adjustment component (209) to move, so that the detection probe (2036) rotates to perform the detection operation. S4. When it is necessary to adjust the position upwards for the next round of testing, the air in the upper sealing airbag (204) is discharged by the blower (2061), and then the telescopic structure (2011) is adjusted upwards by a certain position. Then the two solenoid valves (2063) are opened simultaneously, and the vacuum device (205) is used to evacuate the sealed space between the two sealing airbags (204) for testing. The furnace body (100) is tested section by section by adjusting the position upwards in sequence.
