Description

Technical Field

[0001] This utility model relates to the field of infrared thermal imaging detection, and in particular to an infrared thermal imager. Background Technology

[0002] In the field of water supply pipeline inspection, infrared thermal imagers are widely used to investigate pipeline leaks, blockages, or abnormal heating points due to their non-contact and high-efficiency detection characteristics. Currently, the inspection of water supply pipelines typically requires fixing the infrared thermal imaging equipment to the outside of the pipeline using a clamping device to image and analyze the temperature distribution on the pipeline surface.

[0003] However, current testing equipment generally has the following shortcomings when clamping pipes:

[0004] Fixed clamping limits the imaging angle:

[0005] Existing clamping devices are mostly rigid fixed structures, which can only fix the thermal imaging equipment at a specific position or angle of the pipe. They cannot rotate the pipe or thermal imaging component while clamped, resulting in the acquisition of image data from only one direction or a limited angle of the pipe during the inspection process. If a comprehensive inspection of the circumferential surface of the pipe is required, the clamping position must be adjusted multiple times or the pipe must be manually rotated, which is cumbersome and inefficient. Based on this, we propose an infrared thermal imager. Utility Model Content

[0006] To address the technical problem of limited imaging angle caused by fixed clamping in existing technologies, this invention provides an infrared thermal imager.

[0007] This utility model is achieved using the following technical solution: An infrared thermal imager includes a support leg, with a support column fixedly connected to the top of the support leg. The support leg serves as the basic support structure for the device, stably placing the entire device on the ground or a testing platform. A motor is installed inside the support column, and the output end of the motor is connected to a rotating shaft. A placement plate is fixedly connected to the top of the rotating shaft, and a turntable is rotatably connected to the surface of the placement plate. One end of the support column is fixedly connected to a bracket on the outward side; the other end of the bracket is fixedly connected to a suspension. The bracket has an "L"-shaped structure, with its horizontal end fixedly connected to the support column and its vertical end fixedly connected to one end of the suspension.

[0008] A mounting post is fixedly connected to the bottom of the suspension. The bottom end of the mounting post overlaps with a ring frame. A guide ring groove is provided on the ring frame. A slider is connected to the bottom end of the mounting post, and the slider slidably engages within the guide ring groove. A support assembly is mounted on the ring frame, and an infrared thermal imaging component is mounted on the support assembly.

[0009] The bottom of the support column is fixedly connected to the support leg, and the top is driven by a built-in motor to rotate the shaft and the mounting plate. When the motor starts, the shaft rotates around the central axis of the support column. The shaft drives the mounting plate and the outer fixed support frame, annular frame, and infrared thermal imaging components to rotate horizontally synchronously. Under the action of the rotating disk, the pipeline does not rotate synchronously. The slider connected to the bottom of the mounting column then rotates in a ring within the guide annular groove, realizing the rotation of the water supply pipeline detection direction and enabling the infrared imager to perform a circumferential scan of the pipeline surface, thus solving the problem of fixed detection angle in traditional equipment.

[0010] The support assembly includes a support frame fixedly connected inside the annular frame, a shelf fixedly connected to the inner end of the support frame, and an infrared thermal imaging component fixedly installed on the outer side of the shelf.

[0011] The infrared thermal imaging assembly includes a base, one end of which is fixedly connected to the inner surface of an annular frame, and the other end of which is fixedly connected to a shelf. A guide rail is fixedly connected above the base, a slider is slidably connected to the guide rail, a fixed seat is fixedly connected above the slider, one end of a mounting shaft is rotatably connected inside the fixed seat, and an infrared imager is fixedly connected to the other end of the mounting shaft.

[0012] The infrared thermal imaging component moves circumferentially around the pipeline. Combined with the horizontal sliding of the slider and the angle adjustment of the mounting axis, it can perform a comprehensive, blind-spot-free scan of the pipeline surface from all angles, including critical areas such as joints, elbows, and welds. This allows the equipment to adapt to pipeline inspection needs in different installation environments, eliminating the need for frequent manual adjustments to the pipeline position and significantly improving inspection efficiency and comprehensiveness. Ensuring full circumferential coverage of the pipeline surface, the data processing module ultimately generates a complete infrared thermal image of the pipeline, enabling precise location of leaks, blockages, or abnormal temperature distributions.

[0013] As a further optimization of this utility model, an electric push rod is fixedly installed at the top of the suspension, and an arc-shaped clamp is connected to the output end of the electric push rod. When the electric push rod extends or retracts, it pushes the arc-shaped clamp to slide forward, thereby clamping and fixing the surface of the water supply pipe.

[0014] As a further optimization of this utility model, the guide rail on the base is set in the horizontal direction, and the slider can slide on the guide rail, driving the fixed seat and the mounting shaft to move horizontally, so as to realize the fine adjustment of the position of the infrared imager in the horizontal direction.

[0015] As a further optimization of this utility model, the mounting shaft is rotatably connected to the fixed seat through a bearing, and can rotate around its own axis to adjust the pitch or deflection angle of the infrared imager, so that it can be accurately aligned with different positions on the pipe surface to ensure the acquisition of clear infrared thermal imaging data.

[0016] As a further optimization of this utility model, the guide rail is set on the base in the horizontal direction, the slider can slide along the length of the guide rail, the fixed seat is provided with a rotating hole, and the mounting shaft is rotatably connected to the rotating hole through a damping bearing, so as to realize the rotation of the mounting shaft relative to the fixed seat, thereby adjusting the angle of the infrared imager.

[0017] As a further optimization of this utility model, the support frame includes two parallel support rods. One end of each support rod is fixedly connected to the inner surface of the annular frame, and the other end of each support rod is fixedly connected to the edge of the shelf. The shelf is used to place the water supply pipe to be tested.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model achieves 360° scanning of the pipe surface without blind spots by rotating the annular frame. Compared with the single-angle detection of traditional rigid clamping devices, this structure can automatically complete all-round imaging of the circumferential surface of the pipe, avoiding detection blind spots caused by incomplete angle coverage and significantly improving the comprehensiveness of detection.

[0020] 2. This utility model integrates a guide rail slider horizontal sliding mechanism and a mounting shaft rotation adjustment structure into the infrared thermal imaging component, enabling fine-tuning of the horizontal position and adjustment of the pitch angle of the infrared imager. By sliding the slider along the guide rail, the horizontal distance between the imager and the pipe surface can be precisely controlled; by rotating the mounting shaft around the fixed base, the imaging angle can be flexibly adjusted, ensuring clear imaging of any position on the pipe surface, which is especially suitable for precise detection in complex structures or narrow spaces.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example 1: Please refer to Figures 1-4 This embodiment proposes an infrared thermal imager, including a support leg 1, with a pillar 2 fixedly connected to the top of the support leg 1. The support leg 1 serves as the basic support structure of the device, stably placing the entire device on the ground or a detection platform.

[0029] A motor is installed inside the support column 2. The output end of the motor is connected to a rotating shaft 3. The top end of the rotating shaft 3 is fixedly connected to a shelf 15. A turntable 151 is rotatably connected to the surface of the shelf 15. One end of the support column 2 is fixedly extended outward to a connecting bracket 5. The other end of the connecting bracket 5 is fixedly connected to a suspension 6.

[0030] The technical solution that needs to be explained is that the connecting bracket 5 has an "L" shaped structure, the horizontal end of the connecting bracket 5 is fixedly connected to the column 2, and the vertical end of the connecting bracket 5 is fixedly connected to one end of the suspension 6.

[0031] The bottom end of the suspension 6 is fixedly connected to a mounting post 7, the bottom end of the mounting post 7 overlaps on the annular frame 8, the annular frame 8 is provided with a guide annular groove 9, and the bottom end of the mounting post 7 is connected to a slider, which is slidably connected inside the guide annular groove 9.

[0032] The specific technical solution involves a fixed connection between the bottom end of the support column 2 and the support leg 1, and a drive shaft 3 and a shelf 15 via a built-in motor at the top. When the motor starts, the shaft 3 rotates around the central axis of the support column 2. The shaft 3 drives the shelf 15 and other components such as the support frame 14, the annular frame 8, and the infrared thermal imaging component 13 to rotate horizontally synchronously. Under the action of the rotating disk 151, the pipeline does not rotate synchronously. The slider connected to the bottom end of the mounting column 7 then rotates in a ring within the guide annular groove 9, realizing the rotation of the water supply pipeline detection direction and enabling the infrared imager 136 to perform a circumferential scan of the pipeline surface, thus solving the problem of fixed detection angle in traditional equipment.

[0033] An electric push rod 11 is fixedly installed at the top of the suspension 6. The output end of the electric push rod 11 is connected to an arc-shaped clamp 12. A support assembly is installed on the ring frame 8. An infrared thermal imaging assembly 13 is installed on the support assembly. When the electric push rod 11 extends or retracts, it pushes the arc-shaped clamp 12 to slide forward, thereby clamping and fixing the surface of the water supply pipe.

[0034] The support assembly includes a support frame 14 fixedly connected inside the annular frame 8, a shelf 15 fixedly connected to the inner end of the support frame 14, and an infrared thermal imaging assembly 13 fixedly installed on the outer side of the shelf 15.

[0035] It should be noted that the support frame 14 includes two parallel support rods. One end of each support rod is fixedly connected to the inner surface of the annular frame 8, and the other end of each support rod is fixedly connected to the edge of the shelf 15. The shelf 15 is used to place the water supply pipe to be tested.

[0036] The infrared thermal imaging assembly 13 includes a base 131, one end of which is fixedly connected to the inner surface of the annular frame 8, and the other end is fixedly connected to the shelf 15.

[0037] A guide rail 134 is fixedly connected above the base 131. A slider 132 is slidably connected on the guide rail 134. A fixed seat 133 is fixedly connected above the slider 132. One end of a mounting shaft 135 is rotatably connected inside the fixed seat 133. An infrared imager 136 is fixedly connected to the other end of the mounting shaft 135.

[0038] In a further technical solution, the guide rail 134 is set horizontally on the base 131, the slider 132 can slide along the length of the guide rail 134, the fixed seat 133 is provided with a rotating hole, and the mounting shaft 135 is rotatably connected to the rotating hole through a damping bearing to realize the rotation of the mounting shaft 135 relative to the fixed seat 133, thereby adjusting the angle of the infrared imager 136.

[0039] In a further specific technical solution, the guide rail 134 on the base 131 is arranged horizontally, and the slider 132 can slide on the guide rail 134, driving the fixed base 133 and the mounting shaft 135 to move horizontally, thereby realizing the fine adjustment of the horizontal position of the infrared imager 136. The mounting shaft 135 is rotatably connected to the fixed base 133 through a damping bearing, and can rotate around its own axis, thereby adjusting the pitch or deflection angle of the infrared imager 136, so that it can be accurately aligned with different positions on the pipe surface, ensuring the acquisition of clear infrared thermal imaging data.

[0040] In summary, the infrared thermal imaging component 13 of this invention moves circumferentially around the pipeline, and in conjunction with the horizontal sliding of the slider 132 and the angle adjustment of the mounting shaft 135, it can perform a comprehensive scan of the pipeline surface from all angles, including key areas such as interfaces, elbows, and welds. This allows the equipment to adapt to pipeline inspection needs in different installation environments, eliminating the need for frequent manual adjustments to the pipeline position and significantly improving inspection efficiency and comprehensiveness. It ensures full circumferential coverage of the pipeline surface, and ultimately generates a complete infrared thermal image of the pipeline through the data processing module, enabling precise location of leaks, blockage areas, or abnormal temperature distributions.

[0041] The working principle of an infrared thermal imager according to this utility model is as follows:

[0042] Overall support and basic rotation adjustment

[0043] The water supply pipe is placed on the shelf 15. One end of the electric push rod 11 is fixed to the top of the suspension 6, and the other end is connected to the top of the arc-shaped clamp 12. When the electric push rod 11 extends or retracts, it pushes the arc-shaped clamp 12 to slide forward, thereby clamping and fixing the surface of the water supply pipe.

[0044] Support leg 1 serves as the basic support structure for the equipment, stabilizing the entire device on the ground or testing platform. The bottom of support column 2 is fixedly connected to support leg 1, and the top is driven by a built-in motor to rotate shaft 3 and mounting plate 15. When the motor starts, shaft 3 rotates around the central axis of support column 2. Shaft 3 drives mounting plate 15 and other components such as the externally fixed support frame 14, annular frame 8, and infrared thermal imaging component 13 to rotate horizontally synchronously. Under the action of arc-shaped clamp 12 and rotating disk 151, the pipeline does not rotate synchronously. The slider connected to the bottom of mounting column 7 then rotates in a ring within the guide annular groove 9, achieving rotation of the water supply pipeline detection direction. This enables the infrared imager 136 to perform a circumferential scan of the pipeline's surface, solving the problem of fixed detection angles in traditional equipment.

[0045] Precise positioning and angle adjustment of the infrared thermal imaging component:

[0046] The guide rail 134 on the base 131 is set horizontally, and the slider 132 can slide on the guide rail 134, driving the fixed base 133 and the mounting shaft 135 to move horizontally, so as to achieve fine adjustment of the horizontal position of the infrared imager 136. The mounting shaft 135 is rotatably connected to the fixed base 133 through a bearing, and can rotate around its own axis, thereby adjusting the pitch or deflection angle of the infrared imager 136, so that it can be accurately aligned with different positions on the pipe surface, ensuring the acquisition of clear infrared thermal imaging data.

[0047] The infrared thermal imaging component 13 moves circumferentially around the pipeline. Combined with the horizontal sliding of the slider 132 and the angle adjustment of the mounting shaft 135, it can perform a comprehensive, blind-spot-free scan of the pipeline surface from all angles, including key areas such as joints, elbows, and welds. This allows the equipment to adapt to pipeline inspection needs in different installation environments, eliminating the need for frequent manual adjustments to the pipeline position and significantly improving inspection efficiency and comprehensiveness. Ensuring full circumferential coverage of the pipeline surface, the data processing module ultimately generates a complete infrared thermal image of the pipeline, enabling precise location of leaks, blockages, or abnormal temperature distributions.
